Athletes competing in ultra-endurance events are advised to meet energy requirements, to supply appropriate amounts of carbohydrates (CHO), and to be adequately hydrated before and during exercise. In practice, these recommendations may not be followed because of satiety, gastrointestinal discomfort, and fatigue. The purpose of the study was to assess energy balance, macronutrient intake and hydration status before and during a 1,230-km bike marathon. A group of 14 well-trained participants (VO2max: 63.2 ± 3.3 ml/kg/min) completed the marathon after 42:47 hr. Ad libitum food and fluid intake were monitored throughout the event. Energy expenditure (EE) was derived from power output and urine and blood markers were collected before the start, after 310, 618, and 921 km, after the finish, and 12 hr after the finish. Energy intake (EI; 19,749 ± 4,502 kcal) was lower than EE (25,303 ± 2,436 kcal) in 12 of 14 athletes. EI and CHO intake (average: 57.1 ± 17.7 g/hr) decreased significantly after km 618 (p < .05). Participants ingested on average 392 ± 85 ml/hr of fluid, but fluid intake decreased after km 618 (p < .05). Hydration appeared suboptimal before the start (urine specific gravity: 1.022 ± 0.010 g/ml) but did not change significantly throughout the event. The results show that participants failed to maintain in energy balance and that CHO and fluid intake dropped below recommended values during the second half of the bike marathon. Individual strategies to overcome satiety and fatigue may be necessary to improve eating and drinking behavior during prolonged ultra-endurance exercise.

The Personal Background Preparation Survey (PBPS) identifies students at risk for academic nonadvancement. Uniquely, the PBPS produces individualized reports making evidence-based risk-specific recommendations prescribing interventions targeting students’ empirically identified risk indicators. At a large southwestern health sciences community college, after baseline PBPS administration among 409 diverse first-semester-fall 2010 students, fall 2011 PBPS administration helped target PBPS-individualized interventions among 618 first-semester-fall 2011 students. Group-oriented Advanced Academic Training (AAT) workshops augmented PBPS-targeted individualized interventions among 1,183 additional first-semester students during fall 2012 and fall 2013. AAT participants practiced a daily self-testing retrieval regimen to reduce PBPS-identified cognitive processing, information-, and time-management risk indicators. Controlling PBPS risk level, underrepresented minority status, and gender as covariates, first-semester student nonadvancement rate decreased from baseline’s 42.3% and PBPS-individualized interventions’ 41.4% to 16.2% and 11.6% postAAT ( p < .001), respectively. AAT was designed to reduce primarily higher risk student nonadvancement; yet, retention gains did not differ significantly across risk levels, underrepresented minority students status, and gender.

We describe a new robotic assist device: the passive assist arm (PAS-Arm). PAS-Arms are intended for direct physical interaction with a human operator. PASArms are physically passive. The force to manipulate the arm end must be provided by the operator. Their purpose is not to enhance human strength, but to provide virtual guiding surfaces that constrain and guide the motion of the operator. PAS-Arms have three joints and a three dimensional workspace, but possess only two degrees of freedom due to the reduction of degrees of freedom created by a combination of Continuously Variable Transmissions (CVTs) and differential gears. In this paper, we first discuss the manipulability ellipsoid for the PAS-Arm. The major axis of the ellipsoid is the direction in which the arm end may be easily manipulated, and vice versa. We have developed an experimental system for the PAS-Arm. The CVTs of the experimental system may not adjust the transmission ratio to zero. Second, we describe an algorithm to address that problem. Finally, we present initial experiments that verify the PAS-Arm mechanism. The experimental results successfully produced virtual guiding surfaces.1 1.

AbstractPhenylketonuria (PKU) is an inherited metabolic disorder affecting phenylalanine metabolism. The Irish incidence is 1:4500. Currently, there are 500 patients under the care of the National Centre for Inherited Metabolic Disorders in Temple Street Children's University Hospital. Current practice is to admit PKU patients with phenylalanine (phe) levels that are consistently out of range despite an intensive multidisciplinary team input on an outpatient basis. The aim of this study was to evaluate changes in phe levels pre, during, and post admissions and to examine if there was a sustained impact post discharge. Fifty‐six patients were admitted between January 2003 and December 2013. Patients were all <18 years of age. Greater than 70% (n = 39) of the reasons for admission were due to multiple issues. Average admission time was 5 days. There was a significant decrease in median phe levels from prior to the admission to during the admission. However, there was a significant increase in median phe levels from during the admission (505 μmol/L) to both the 1‐6 months' and 7‐12 months' time points (618 and 651 μmol/L, respectively). The results highlight that while inpatient admissions can stabilize levels within the acute setting, this is not sustained long term. The ward environment does not accurately replicate home circumstances. This study highlighted that the reasons for admission are most often multifactorial, which is less likely to be resolved during a brief admission period.

Abstract Self-hardening moulding sands with water-glass hardened by liquid esters are applied in several foundry plants for making moulds for the production of heavy iron and steel castings. The main good point of this process is a low cost of sands. However, on account of a low susceptibility of this moulding sand for the matrix reclamation the fraction of sands originated from the reclamation is limited. The investigations presented in this work were aimed at the determination of the addition of the reclaimed material, obtained in the dry mechanical reclamation, on properties of the moulding sand with the Geopol 618 binder, which is water-glass modified by polymers and hardened by esters.

SUMMARYAlthough contamination of food can occur at any point from farm to table, restaurant food workers are a common source of foodborne illness. We describe the characteristics of restaurant-associated foodborne disease outbreaks and explore the role of food workers by analysing outbreaks associated with restaurants from 1998 to 2013 reported to the Centers for Disease Control and Prevention's Foodborne Disease Outbreak Surveillance System. We identified 9788 restaurant-associated outbreaks. The median annual number of outbreaks was 620 (interquartile range 618–629). In 3072 outbreaks with a single confirmed aetiology reported, norovirus caused the largest number of outbreaks (1425, 46%). Of outbreaks with a single food reported and a confirmed aetiology, fish (254 outbreaks, 34%) was most commonly implicated, and these outbreaks were commonly caused by scombroid toxin (219 outbreaks, 86% of fish outbreaks). Most outbreaks (79%) occurred at sit-down establishments. The most commonly reported contributing factors were those related to food handling and preparation practices in the restaurant (2955 outbreaks, 61%). Food workers contributed to 2415 (25%) outbreaks. Knowledge of the foods, aetiologies, and contributing factors that result in foodborne disease restaurant outbreaks can help guide efforts to prevent foodborne illness.

On the basis of the theoretical concept for the use of small gauge volumes to study near-surface residual stress fields with high spatial resolution [Meixner, Klaus & Genzel (2013).J. Appl. Cryst.46, 610–618], the experimental implementation of the approach is demonstrated. It is shown that specifically designed slit systems are required to avoid effects such as diffuse scattering at the slit blades and total external reflection, both giving rise to a reduced resolution. Starting from the characterization of the small gauge volume, practical guidance on how to control the alignment of the sample relative to the gauge volume for different geometrical conditions of energy-dispersive diffraction is given. The narrow-slit configuration as well as the formalism for data evaluation introduced in the first part of this series is applied to the analysis of a very steep in-plane residual stress gradient in a shot-peened Al2O3ceramic sample. The results are compared with those obtained by means of a conventional wide-slit setup using the classical universal plot method for residual stress analysis on the one hand, and with the simulations performed in the first part on the other hand.

As there is a dynamic relation between religious cultural heritage, tourism and local development, the European Union supports preservation of religious heritage through regional policy funds available in Poland under operational programmes. The aim of the research was to define and look into the main outcomes of this support, based on qualitative and quantitative data from SIMIK 2007–2013 and central teleinformation system (CTS) SL2014 for 2014–2020. Findings show that the 618 projects for the preservation of religious cultural heritage in Poland comprised a very small share of all investments under operational programmes. They were also a very small share of the total value of all projects and of EU funding co-financing them. However, comparing the financial perspective of 2007–2013 and 2014–2020, there is an increase in the number of these investments and in the number of projects that obtained the best relation of EU funding to their total value, i.e. 85%.

Organomineral fertilisers (OMFs) were produced by coating biosolids granules with urea and potash. Two OMF formulations with N : P2O5 : K2O compositions: 10 : 4 : 4 (OMF10) and 15 : 4 : 4 (OMF15) were developed for application in grassland and arable crops. Routine fertiliser analyses were conducted on four batches of OMF and biosolids granules and compared with a sample of urea to determine key physical and chemical properties of the materials which affect handling and spreading, soil behaviour, and fertiliser value. Bulk and particle densities were in the range of 608 to 618 kg m−3, and 1297 to 1357 kg m−3, respectively. Compression tests showed that OMF particles undergo deformation followed by multiple failures without disintegration of the granules when vertical load was applied. Static particle strength was between 1.18 and 4.33 N mm−2depending on the particle diameter. The use of a model for fertiliser particle distribution studies showed that OMF granules should be between 1.10 and 5.50 mm in diameter with about 80% of the particles in the range of 2.25 to 4.40 mm to enable application at 18 m tramline spacing. This research utilises novel technology to improve the fertiliser value of biosolids, reduce disposal costs, and deliver a range of environmental benefits associated with recycling.

Abstract Background The impact of 13-valent pneumococcal conjugate vaccine (PCV13) introduction on the occurrence of first and subsequent otitis media (OM) episodes in early childhood is unclear. We compared the risk of OM episodes among children age <2 years before and after PCV13 introduction, accounting for the dependence between OM episodes. Methods We identified consecutive annual (July–June) cohorts of Tennessee Medicaid–enrolled children (2006–2014) from birth through age 2 years. We identified OM episodes using coded diagnoses (we classified diagnoses <21 days apart as the same episode). We modeled adjusted hazard ratios (aHRs) for OM comparing 7-valent pneumococcal conjugate vaccine (PCV7)–era (2006–2010) and PCV13-era (2011–2014) birth cohorts, accounting for risk factors and dependence between first and subsequent episodes. Secondary analyses examined pressure equalization tube (PET) insertions and compared the risk of recurrent OM (≥3 episodes in 6 months or ≥4 episodes in 12 months) between PCV7- and PCV13-era birth cohorts. Results We observed 618 968 OM episodes and 24 875 PET insertions among 368 063 children. OM and PET insertion rates increased during the PCV7 years and declined after PCV13 introduction. OM and PET insertion risks were lower in the 2013–2014 cohort compared with the 2009–2010 cohort (aHRs [95% confidence interval], 0.92 [.91–.93] and 0.76 [.72–.80], respectively). PCV13 introduction was associated with declines in the risk of first, subsequent, and recurrent OM. Conclusions The transition from PCV7 to PCV13 was associated with a decline of OM among children aged <2 years due to a reduction in the risk of both the first and subsequent OM episodes.

O objetivo da análise estrutural é determinar os efeitos das ações em uma estrutura, com a finalidade de efetuar verificações de estados limites últimos e de serviço (NBR 6118:2003 Projeto de estruturas de concreto). A análise estrutural consiste numa das principais etapas do projeto estrutural de um edifício, pois compreende a escolha dos modelos teóricos, que devem representar adequadamente a estrutura real, e do tipo de análise, com relação ao comportamento dos materiais. Visa-se, com este trabalho, aproximar o meio técnico do acadêmico, e tornar mais acessível a parte da NBR 6118:2003 que trata da análise estrutural. Neste trabalho consideram-se os modelos estruturais mais utilizados, no cálculo de edifícios, e os principais conceitos relativos aos diferentes tipos de análise permitidos pela norma. Em seguida são realizados exemplos de elementos lineares, pelos diferentes tipos de análise, com ênfase na redistribuição de esforços, empregando-se análise linear com redistribuição ou análise plástica. Ressalta-se a importância da consideração de seção T nas vigas e os ajustes necessários quando da consideração de uma envoltória de carregamentos. Tem-se ainda um exemplo de um edifício de oito pavimentos, que visa demonstrar as diferenças nos esforços ou nos deslocamentos obtidos com modelos estruturais distintosThe structural analysis objective is to determine the actions effects in a structure, with the purpose of verifying the ultimate limit states and serviceability (brazilian code NBR 6118:2003 - Design of concrete structures). The structural analysis is one of the main parts of a building structural design, since it involves the choice of theoretical models that represent appropriately the real structure, and the type of analysis due to the materials behavior. This work intends to shorten the distance between design engineers and the academic world, providing a clearer vision of the NBR 6118:2003 structural analysis approach. This work considers the most common structural models used for buildings, and the theory concerning the different types of analysis permitted by the brazilian code. It presents simple examples of linear elements computed by different types of analysis, emphasizing the moment redistribution possibility, either with the linear analysis with redistribution or the plastic analysis. The importance of considering T-beam with moment redistribution is made clear, and lines of direction to consider alternate position of live loads are given. The last example presents an eight store building, and its differences relative to efforts and displacements, obtained by distinct structural models

El verdadero impacto del tratamiento antivírico en pacientes críticos no estaba establecido en el inicio de la pandemia por gripe A (H1N1) del 2009 debido a la falta de estudios aleatorizados en este tipo de pacientes. Por ello, las autoridades sanitarias establecieron un conjunto de directrices y estrategias encaminadas a optimizar y estandarizar la terapia antivírica en los pacientes críticos que incorporaban la evidencia y conocimientos disponibles hasta ese momento. Se debía administrar tratamiento antivírico lo antes posible a todas las personas que requieran hospitalización, que tuvieran una enfermedad progresiva grave o que cursara con complicaciones, y esto debía hacerse con independencia del estado de salud previo o de los antecedentes de vacunación. Oseltamivir a dosis altas (150 mg/12 h) y con duraciones de tratamiento superiores a 10 días debía administrarse a pacientes con neumonía, especialmente en obesos (IMC>30) argumentando la existencia de mayor volumen de distribución. También se aconsejaba esta dosificación a pacientes graves, sobre todo si requerían ventilación mecánica invasiva. Estas pautas fueron aplicadas según decisiones de cada centro y de cada prescriptor con lo que existió una brecha entre las recomendaciones emitidas y la práctica habitual que tuvo lugar, dando lugar a una falta de actitud terapéutica homogénea y por ello un bajo grado de adherencia a los protocolos terapéuticos que pudo condicionar el pronóstico del paciente.

Objetivos La evaluación y comparación del grado de adherencia a los protocolos de tratamiento emitidos por las autoridades sanitarias durante la pandemia de gripe A (H1N1) del 2009 y del periodo post pandémico del 2010-2011 es por tanto el objetivo principal de esta trabajo. A su vez, son también objetivos de este estudio la descripción y análisis de los factores asociados a mortalidad durante la pandemia de gripe A (H1N1) 2009 y el periodo postpandémico del 2010-11 y la repercusión económica de la no adherencia al tratamiento recomendado.
Material y métodos
Análisis secundario a un estudio prospectivo, observacional y multicéntrico de dos cohortes de pacientes adultos con casos confirmados de gripe A (H1N1) 2009 e ingresados en unidades de críticos (UCI) de 148 hospitales españoles.
Resultados
Fueron recopilados los resultados de 1058 pacientes con datos completos e ingresados en las UCI con infección confirmada de gripe A (H1N1) e insuficiencia respiratoria graves, 661 (62,5%) del periodo pandémico del 2009 y 397 (37,5%) del periodo postpandémico del 2010-11. Los pacientes que ingresaron en las UCI españolas durante estos dos periodos, recibieron tratamiento antivírico empírico en un 72% y no fueron observadas diferencias estadísticamente significativas entre ambos periodos. Para la pandemia de gripe A (H1N1) del 2009 la media de días que transcurrieron desde el inicio de los síntomas al inicio del tratamiento antivírico fue de 4,7 (2,9) días, durante el periodo post pandémico del 2010-11, este tiempo fue significativamente superior 5,7 (3,6) días. Tan sólo un 23,9 % de los pacientes del periodo pandémico y un 15,8 % de los pacientes del periodo post pandémico del 2010-11 recibieron el tratamiento antivírico precoz (≤ 48 h del inicio de la sintomatología), periodo recomendado en las guías de tratamiento. La adherencia global en el estudio se situó en el 41,6% no existiendo diferencias estadísticamente significativas entre ambos periodos.
Para el grupo de pacientes con criterios de mayor gravedad, existió una mayor adherencia a los protocolos de tratamiento durante el periodo de la pandemia del 2009 (54,4% vs. 36,4% p>0,001). Por el contrario para el grupo de pacientes, sin requerimientos de dosis y duración de

tratamiento elevadas, el grado de adherencia mejoró durante el 2010-11 (41,5% vs. 25,9% p=0,003).
El total de pacientes fallecidos durante los dos periodos fue de 263 (24,9%). La mortalidad fue significativamente mayor en los pacientes del brote estacional del 2010-11, 119 (30%) vs. 144 (21,8%) en la pandemia del 2009 (p<0.001).
El análisis multivariante confirmó que la enfermedad hematológica y la gravedad marcada por el APACHE II, fueron factores independientemente asociados a una peor evolución en ambos periodos evaluados. La adherencia al tratamiento fue un factor protector de muerte en ambos periodos y el tratamiento antivírico precoz lo fue también durante el periodo pandémico. El análisis económico de minimización de costes para el grupo de pacientes sin criterios de gravedad establece el coste global de la “No Adherencia” en 559.875 €. Esta cifra supone que un 21,58% de los costes globales sanitarios calculados durante la pandemia del 2009 y el periodo post pandémico podrían haber sido ahorrados mediante la adherencia a los protocolos. Por el contrario en el grupo de pacientes con criterios de gravedad, el análisis de coste efectividad establece el coste global de la “Adherencia” en 3.081.510 € y el coste-efectividad incremental en 71.190€. Conclusiones La adherencia al protocolo de tratamiento para los pacientes graves infectados por el virus de la gripe A (H1N1) fue globalmente baja aunque similar en ambos periodos evaluados. La falta de adherencia y el retraso en el inicio del tratamiento antivírico fueron variables asociadas a mortalidad en pacientes ingresados en UCI infectados por el virus de la gripe A (H1N1). Para el conjunto de pacientes sin criterios de gravedad, el no seguimiento del protocolo de tratamiento supuso un coste adicional del 21,58% en los costes globales sanitarios de ambos periodos. Para el grupo de pacientes mas graves, el coste-efectividad incremental de la adherencia al tratamiento por paciente se sitúa en 10.170 € por paciente

Previous issue date: 2017-12-15Esta dissertação trata do dimensionamento otimizado de pilares de concreto armado. Apresenta as formulações adotadas para o dimensionamento de seções retangulares, circulares, hexagonais e em U moderadamente esbeltas. Aborda, também, seções retangulares esbeltas em apenas uma das direções. Os cálculos são baseados na norma que define o procedimento para o projeto de estruturas de concreto, NBR 6118:2014. Assim, compreende concretos de resistência característica à compressão entre 20 e 90 MPa. O programa computacional desenvolvido foi implementado na plataforma Matlab, e utiliza o Método dos Pontos Interiores como algoritmo de otimização. Reúne exemplos que atestam a validade do programa computacional desenvolvido, bem como verificam as influências de determinadas características no dimensionamento. O estudo indica que o maior número de parâmetros liberados para a otimização permite uma redução considerável do custo total dos pilares. Palavras Chave: Dimensionamento. Pilares. Otimização. Concreto de alta resistência. Esbeltez.

Several studies have demonstrated the economical feasibility of the utilization of highstrength concrete (HSC) in the lower columns of high- and medium-rise buildings. Several international codes have already updated their recommendations to deal with this relatively new material. In spite of the recent revision of the NBR 6118:2003, the Brazilian code has its range of applicability limited to 50 MPa concrete characteristic strengths. However, higherstrength concretes are being successfully used in Brazil and the nonexistence of design recommendations related to this material represents an impediment to the safe and economicalutilization of HSC. Due to its large application, type of failure, and importance to structural integrity, the safety evaluation of HSC columns is a very important issue. In the case of columns, several design parameters are uncertain (concrete compressive strength, cross-sectional dimensions, loads, etc.). As such, safety can be established in probabilistic terms only. In order to simplify the design process, the prescribed reliability levels are introduced in the design codes, in an implicit manner, through the partial safety factors in the limit states design format. As such, the main objectives of this research are: (i) evaluate the reliability levels implicit in NBR 6118:2003 and NBR 8681:2003 for the design of short columns subjected to axial loads and uniaxial bending; (ii) select target reliability levels; (iii) evaluate the influence of design parameters in the resulting reliability levels; (iv) recommend adjustments in the NBR 6118:2003 provisions in order to extend the range of application of this code up to 80 MPa characteristic strengths. The results obtained have shown that, for 50 MPa characteristic strengths, the NBR 6118:2003 provisions imply in reliability levels smaller than those obtained for 20 to 35 MPa columns. Also, the mere extrapolation of current recommendations for 65 or 80 MPa concretes would result in low reliability levels. Nevertheless, adjustments in the equivalent stress block, while other recommendations remain unchanged, would result in adequate reliability levels for all the concrete strengths investigated.Estudos realizados em diversos países demonstram a viabilidade econômica do uso do concreto de alta resistência (CAR) em pilares de pavimentos inferiores de construções altas, assim como nas de médio porte. Várias normas técnicas internacionais já se ajustaram a estanova realidade. No caso brasileiro, a despeito da recente revisão da NBR 6118:2003, esta norma tem os concretos de classe C50 como limite de aplicação. Entretanto, a utilização de concretos de resistência superiores a este limite já vem sendo feita com sucesso em territórionacional e a inexistência de documentos normativos que atendam a esta nova realidade representa um empecilho para a utilização segura e econômica deste material. Dada a sua crescente utilização, tipo de falha e importância para a integridade estrutural, a avaliação da segurança de pilares em concreto de alta resistência é assunto da maior relevância. No caso de pilares, vários parâmetros envolvidos no projeto estrutural são incertos (resistência à compressão do concreto, dimensões da seção transversal, cargas atuantes etc.). Desta maneira, a segurança estrutural pode ser definida apenas em termos probabilísticos. Visando a simplificação do processo de cálculo, as normas de projeto mantêmde forma implícita o nível de confiabilidade prescrito através dos fatores parciais utilizados no método dos estados limites. Desta maneira, os principais objetivos deste trabalho são: (i) avaliar os níveis deconfiabilidade implícitos na NBR 6118:2003 e NBR 8681:2003 para projeto de pilares curtos em concreto armado sob flexo-compressão normal; (ii) identificar os níveis de confiabilidade alvo a serem atingidos; (iii) avaliar a influência dos diversos parâmetros de projeto nos níveis de confiabilidade obtidos; (iv) recomendar ajustes na NBR 6118:2003 visando o projeto de pilares curtos em concreto com resistência característica de até 80 MPa de forma a se obter uma maior uniformização dos níveis de confiabilidade. Os resultados obtidos indicam que, para fck igual a 50 MPa, os critérios da NBR 6118:2003 implicam em pilares com níveis de confiabilidade inferiores àqueles em concretos com fck de 20 a 35 MPa. Foi observado também que a mera extrapolação das recomendações da NBR 6118:2003 para concretos com fck de 65 e 80 MPa resulta em índices de confiabilidade baixos. Contudo, ajustes no bloco de tensões, mantendo todas as outras recomendações da NBR 6118:2003, resultam em níveis adequados de confiabilidade para todas as faixas de resistência analisadas.

As demandas do mercado da construção civil têm exigido vãos cada vez maiores e ao mesmo tempo alturas cada vez menores das vigas. Isto tem levado muitos projetistas à adoção da solução do pavimento em laje lisa em concreto armado ou protendido. No entanto, a ausência das vigas torna possível a ruptura das lajes por puncionamento junto aos pilares. A norma NBR-6118:2014 prescreve as disposições para o projeto de lajes sob punção. O trabalho proposto teve como objetivo principal a análise da confiabilidade da ligação laje-pilar interno sob o efeito da punção em lajes que se apoiam diretamente sobre pilares de acordo com a NBR-6118:2014. Primeiramente, com o intuito de se entender melhor o fenômeno da punção, realizou-se uma breve revisão bibliográfica, identificando os principais parâmetros que influenciam na resistência da ligação, assim como os principais métodos de análise e trabalhos realizados na área. Em seguida, estudou-se o software de análise em elementos finitos ANSYS (Analysis Systems Incorporated), especificamente a ferramenta UPF (User Programmable Features), que foi utilizada para adoção de um modelo constitutivo para o concreto. Utilizando o software, foram modeladas lajes estudadas por outros autores, visando a validação do modelo numérico. Para o estudo da confiabilidade foi dimensionado um conjunto de lajes lisas seguindo as prescrições da NBR 6118:2014. A análise da confiabilidade foi realizada utilizando a ferramenta PDS (Probabilistic Design System), empregando o método de simulação numérica de Monte Carlo com amostragem por Latin Hypercube. Por fim, determinou-se o índice de confiabilidade em cada projeto e realizaram-se análises paramétricas com as variáveis adotadas no trabalho. Os resultados obtidos mostraram que as lajes lisas sem armadura de cisalhamento projetadas segundo a NBR 6118:2014 obtiveram, em sua maioria, índices de confiabilidade adequados. Porém, para as lajes lisas com armadura de cisalhamento, o índice de confiabilidade foi, em grande parte, menor que o índice de confiabilidade alvo adotado.The demands of the construction market have required increasingly large spans while diminishing of the beam heights. This has led many designers to adopt the pavement solucion of reinforced or prestressed concrete flat slab. However, the absence of the beams makes it possible to slabs failure by punching shear. The Standard NBR-6118: 2014 prescribes the requirements for the design of slabs under punching. The aim of this work was to analyze the reliability of the internal slab-column intersection under punching in slabs supported directly on columns according to NBR-6118: 2014. Firstly, in order to better understand the punching phenomenon, a brief bibliographic review was carried out, identifying the main parameters that influence the connection strength, as well as the main methods of analysis and published in the area. Then, the finite element analysis software ANSYS (Analysis Systems Incorporated), specifically the UPF (User Programmable Features) tool, was used to adopt a concrete constitutive model. Using the software, slabs studied by other authors were modeled, aiming at the validation of the numerical model. For the reliability study, a set of flat slabs was designed following the requirements of NBR 6118: 2014. The reliability analysis was performed using the PDS (Probabilistic Design System) tool, using the Monte Carlo numerical simulation method with Latin Hypercube sampling. Finally, the reliability index was determined in each project and parametric analyzes were performed with the variables adopted in the study. The results from this study show that the flat slabs without shear reinforcement designed according to NBR Standarts obtained appropriate reliability index. However, for the flat slabs with shear reinforcement, the reliability index, in most cases, did not achieve the target reliability index.

The Brazilian code NBR 6118/2003 introduces significant changes in the criteria for the shear strength of reinforced concrete (RC) beams. Two design models are presented and in one of them allowance is given to the designer to vary the inclination of the compressive struts ¦È between 30º and 45º In this scenario, the objective of this work is to evaluate these shear design procedures with respect to experimental results of RC beams, with and without stirrups built with normal (fc < 50MPa) and high-performance (fc > 50MPa). The effects of the transversal and longitudinal reinforcement rates, beam effective depth and concrete compressive concrete strength are investigated in the comparative study. EUROCODE 2/2003 and ACI 318/2005 shear design criteria arealso analyzed. The data basis of experimental results is composed of 522 beams from which 311 have transversal reinforcement. The comparative analysis strongly suggests the revision of NBR 6118 design equation for the concrete contribution in the shear strength of RC beams. The effects of longitudinal reinforcement rate and beam effectivedepth must be explicitly included in the formulation. The overall comparative analysis indicates that NBR 6118 design criteria (model II with ¦È equals to 30º) provides the best correlation with respect to test results in terms of safety, precision and economy of beams with stirrups and concrete compressive strength up to 50 MPa. Poor correlationof these design criteria was, however, obtained for beams with effective depth greater than 60 cm and longitudinal reinforcement rate below 2%.Keywords: reinforced concrete beams, shear, design codes.A nova NBR 6118/2003, Projetos de Estruturas de Concreto - Procedimento, traz mudancas significativas em seus criterios de dimensionamento ao cisalhamento em vigas de concreto armado. Dois modelos de calculo sao apresentados sendo que um deles permite a variacao da inclinacao das bielas de concreto entre 30º e 45º. Dentro deste cenario, o objetivo desta dissertacao e avaliar estes criterios por meio da comparacao com resultados experimentais encontrados na literatura de vigas, com e sem armadura transversal e executadas com concreto convencional (fc < 50MPa) e de alto desempenho (fc > 50MPa). Os parametros incluidos na analise sao as taxas de armadura transversal e longitudinal de flexao, a resistencia do concreto e a altura util das vigas.Os criterios do ACI 318/2005 e do EUROCODE 2/2003 sao tambem analisados. Para o estudo comparativo com relacao a resultados experimentais foi criado um banco de dados composto de 522 vigas, das quais 311 possuem armadura transversal. A analise comparativa indica que a formulacao da NBR 6118 para a parcela da forca cortante absorvida pelos mecanismos complementares ao de trelica deve ser reformulada incluindo de forma explicita os efeitos da altura util da viga e da taxa de armadura longitudinal de flexao. No geral, a melhor correlacao, em termos de seguranca, precisao e economia, foi obtida, entre todas as normas analisadas, com o modelo II da NBR6118 e inclinacao ¥è igual a 30º para vigas armadas transversalmente e fabricadas com concreto de resistencia a compressao de ate 50MPa. Entretanto, esses criterios da NBR 6118 apresentaram desempenho inferior com relacao a seguranca no caso de vigas com altura util maior que 60 cm ou com taxa de armadura longitudinal de flexao menor que2%.

Partindo do pressuposto de que a formação continuada de professores desenvolvida no contexto da prática tem a finalidade de propor reflexões e orientar a prática docente, a presente dissertação investiga a utilização do tempo da Hora de Trabalho Pedagógico Coletivo (HTPC) por uma escola da rede municipal de Limeira e, em decorrência das constatações da pesquisa, propõe um programa para a melhoria da gestão desse momento. A partir de uma abordagem qualitativa, este estudo de caso foi desenvolvido por meio da análise documental e da realização de entrevistas. Os dados documentais foram coletados do Plano Gestor e dos registros das pautas da HTPC da escola, da Lei Complementar nº 613/2011 e da Lei Federal nº 11.738/2008. As informações sobre os participantes da pesquisa foram obtidas por meio de entrevistas, na modalidade semiestruturada, e de questionários. Objetivou-se com a aplicação desses instrumentos, obter a versão legal e captar a opinião dos profissionais sobre a LC nº 613/2011, assim como investigar quais são as atividades desenvolvidas na HTPC. Foram realizadas entrevistas com a diretora e com a coordenadora da escola, bem como com o coordenador do sindicato dos professores do ensino oficial do estado de São Paulo. O acesso aos professores da escola, por sua vez, deu-se a partir da aplicação de questionário. A pesquisa apontou que a implementação da LC nº 613/2011, na rede municipal de Limeira, não foi acompanhada de ações que subsidiassem o trabalho desenvolvido pela equipe gestora da escola, de forma que esta não está preparada para o desenvolvimento da formação do professor. Uma das consequências verificadas foi o fato de o uso do espaço da HTPC mostrar-se tomado por demandas administrativas e burocráticas. Além disso, observou-se que os horários nos quais os encontros acontecem são inadequados ao trabalho coletivo. Conclusivamente, este estudo mostra que, ter assegurado, em lei, tempo para o desenvolvimento do trabalho pedagógico e formação docente não significa que essas ações aconteçam. Dessa forma, como desdobramento da pesquisa, foi elaborado um plano de ação educacional com algumas indicações que podem contribuir para o desenvolvimento de uma formação de professores centrada na escola: a reorganização do tempo da HTPC, a formação do professor crítico reflexivo, o compartilhamento de decisões por meio de uma gestão democrática participativa e o desenvolvimento de um trabalho coletivo.
Based on the assumption that the continued training of teachers developed in the context of the practice has the purpose of propose reflections and guide the teaching practice, this dissertation investigates the use of the time of the Time for Pedagogic Collective Work (TPCW) by a municipal public school of the city of Limeira and, as a consequence of the research observations, proposes a program to the improvement of the management of this moment. From a qualitative approach, this case study was developed through the documental analysis and interviews. The documental data were collected from the Manager Plan and from the register of the agendas of the TPCW of the school, from the Supplementary Law nº 613/2011 and from the Federal Law nº 11.738/2008. The interviews were applied in two ways: the semi-structured and the questionnaire. The aim of the application of these instruments is obtain the legal version and capture the opinion of the professionals about the Supplementary Law nº 613/2011, as well as investigate what are the activities undertaken in the TPCW. It was conducted interviews with the director and the coordinator of the school, as well as with the coordinator of the school teachers' union of the official education of São Paulo State. The access to the teachers in the school, in its turn, occurred from the questionnaire application. The research showed that the implementation of the Supplementary Law nº 613/2011, municipal public schools of the city of Limeira, was not accompanied by actions that subsidize the work developed by the management team of the school, so that it is not prepared for the development of the teacher training. One of the consequences checked was that the use of space of the TPCW reveal itself taken by administrative and bureaucratic demands. Furthermore, It is noted that the times in which the meetings take place are inadequate to the collective work. Conclusively, this study shows that have secured, by the law, time for the development of the pedagogical work and teacher training does not mean that these actions happen. Thus, as extension of the research, was prepared an educational action plan with indications which may contribute to the development of a training of teachers focused on the school: the time reorganization of the TPCW, the teacher training critical reflective, the sharing of decisions through a democratic participative management and the development of a collective work.

Conciliar la maternidad y el trabajo, y avanzar en la equidad de género, son temas de creciente interés global que están generando políticas innovadoras, sin embargo, apenas conocemos su impacto. Internacionalmente, las políticas de protección a la maternidad han sido escasamente evaluadas, tanto en su efectividad como –más aún- en su equidad. Chile promulgó la Ley 20.545 sobre Protección a la Maternidad en 2011 con el objetivo de aumentar el acceso y la equidad en la protección a la maternidad de las mujeres que trabajan remuneradamente. Esta tesis desarrolla una evaluación empírica original y una propuesta metodológica innovadora que evalúa los resultados de esta importante política pública, en un país con profundas desigualdades sociales. Los principales resultados de este análisis muestran que ha habido un avance en el acceso a la protección de la maternidad, pero no hubo una mejora en la equidad en los distintos grupos de mujeres trabajadoras. Para lograr un avance sustancial en la equidad de acceso a la protección a la maternidad, deberán realizarse nuevas políticas que reduzcan los requisitos para incluir a una mayor cantidad de trabajadoras con empleo informal.Reconciling maternity and work-life balance, and advancing gender equity, are topics of growing global interest, that are generating innovative policies, however, we barely know their impact. Internationally, maternal protection policies have been poorly evaluated, both in terms of their effectiveness and - moreover - their equity. Chile enacted Law 20,545 on Maternity Protection in 2011, with the objective of increasing access and equity in maternity protection for women who work for pay. This thesis develops an original empirical evaluation and an innovative methodological proposal that evaluates the results of this important public policy, in a country with profound social inequalities. Main results of this analysis show that there has been progress in access to care, but not in equity of benefits to every working woman. To achieve substantial advance in equitable access to maternity protection, new policies should be made that reduce requirements to access maternity protection benefits to include more women with informal employment.

AbstractRainfall infiltration in unsaturated soil slopes is a classic issue in geotechnical engineering (Conte and Troncone in Géotechnique 62:87–91, 2012; Morbidelli et al. in J Hydrol 557:878–886, 2018). Factors influencing the soil slope stability due to rainwater infiltration comprise the rainfall characteristics, the saturated permeability coefficient, the geometry of the slope, and the boundary and initial soil moisture conditions (Ali et al. in Comput Geotech 61:341–354, 2014; Wu et al. in Hydro-mechanical analysis of rainfall-induced landslides.

AbstractThis chapter explores how asylum caseworkers are socialised on the job and thereby acquire an institutional habitus. Decision-makers are disciplined, incentivised, compelled, but also “ideationally conditioned” (Gill in Transactions of the Institute of British Geographers 34 (2): 215–233, 2009) to think, act and feel in certain ways. The chapter argues that how organisational socialisation works can only be understood by taking three factors into account: what belonging to the office and to different “communities of interpretation” (Affolter, Miaz, and Poertner in Asylum Determination in Europe: Ethnographic Perspectives. Palgrave Macmillan, Cham, pp. 263–284, 2019; Wenger in Knowing in Organizations: A Practice-Based Approach. M.E. Sharp, Armonk, pp. 76–99, 2003) within the office means; how decision-makers acquire, and are taught, the necessary Dienstwissen (Weber in Economy and Society. University of California Press, Berkeley, 2013 [1978]) for carrying out their tasks; and the accountability decision-makers feel towards other actors: peers and superiors, but also politicians, the media and “the public”. Together these aspects of organisational socialisation shape what decision-makers come to perceive as “normal” and “appropriate” practices. Through becoming members of the office, they develop a “socialised subjectivity” (Bourdieu and Wacquant in An Invitation to Reflexive Sociology. Polity Press, Cambridge, pp. 61–215, 1992) which, in turn, shapes their everyday decision-making practices.

AbstractInfiltration into soil slopes is a fundamental concern in civil engineering. Rainfall infiltration leads to changes in pore-water pressure and reduces matric suction in soils, making it one of the main triggers of slope failure (Ali et al. in Comput Geotech 61:341–354, 2014; Wu et al. in Hydro-mechanical analysis of rainfall-induced landslides. Springer, 2020). Slope instabilities caused by water infiltration are called rainfall-induced landslides (Xu and Zhang in Landslides 7:149–156, 2010; Wu et al. in Hydro-mechanical analysis of rainfall-induced landslides. Springer, 2020).

AbstractIn 2014 the Island of El Hierro (Canary Islands) was declared a Geopark of the Unesco network, thus becoming the first UNESCO geopark of the Canary Islands. The geological history of the Island of El Hierro can be understood through the visit of 61 geosites, which are representative of the growth and destruction of an oceanic Island in an intraplate environment. The geological heritage represented by these geosites has as foremost exponents those related to the formation of mega-landslides and the formation of extensive fields of pahoehoe lava-flows related to the historical or prehistoric fissure volcanism concerning the activity of its three rifts. This chapter describes the methodology used in establishing the geosite inventory carried out in 2019, as well as the description of the established geosites.

AbstractKorean people share a cultural emotion called jeong (정 情), which generally means intimacy or love. The Korean word jeong literally means “emotions” or “feelings” but also refers to complicated but intimate feelings that are influenced by various Korean philosophical traditions. Buddhism offers the crucial foundation of the Korean concept jeong with the notion of hanmaum (한마음), an indigenous Korean words for “one mind (or heart-mind) (ilsim 일심 一心).” Hanmaum supports the idea of interconnectedness among people; jeong is deeply rooted in this notion. This chapter explores it in the thought of Wonhyo (元曉; 617–686) and Daehaeng (1927–2012).

AbstractThis chapter builds on an assessment of infringement proceedings in the EU rule of law crisis that we previously published in the Common Market Law Review. We offer a close reading of two recent prominent infringement cases by the European Commission against Poland (cases C-619/18 and C-192/18). Noteworthy advancements in EU law made with them are in particular a clarification on the parallel use of Articles 7 TEU and 258 TFEU, the use of both interim relief and an expedited procedure prior to the judgment, and, as regards the merits, further substance for the functioning of Articles 19 TEU and 47 of the EU Charter of Fundamental Rights regarding the operationalisation of the rule of law in EU law. We offer a critical assessment of the Court’s findings and contextualise in light of two Commission communications on the rule of law published in 2019.

AbstractMore than 617 million children and adolescents lack the basic reading and mathematics skills required to live healthy and productive lives. Malawi ranks particularly poorly, with an average pupil to teacher ratio of 77:1 and a 50% dropout rate among primary school children. Established in 2013, the Unlocking Talent initiative uses e-Learning technology to help overcome educational challenges. It equips touch-screen tablets with customisable software that delivers lessons through multisensory experiences (e.g. pictures, sound, video and animation). Throughout Malawi, small groups of students in public primary schools have accessed these tablets during weekly sessions on-site. This case study describes a series of evaluations of this e-Learning technology in Malawi, conducted in tandem with experiments in other countries (including the United Kingdom, Brazil, South Africa, Tanzania, Kenya and Ethiopia). Following a pilot evaluation to assess the feasibility of e-Learning in raising learning outcomes, multiple large-scale randomised control trials were conducted. Learning gains hold across multiple cohorts of children and across different countries, generating more than a 3-month advantage in basic mathematics and more than a 4-month advantage in basic reading on average. The intervention also bridges gender gaps in mathematics skills attainment in Malawi.

AbstractThis chapter complements previous chapters by applying the concept of ‘sisu’ to the enactment of persistence and success of mature FiF women in higher education. Sisu is a Finnish term which describes the inner fortitude activated in moments of hardship especially when nothing more is ‘left in the tank’, likened to the ‘second wind’ that keeps us moving forward in spite of the odds (Lahti, Embodied fortitude: An introduction to the Finnish construct of sisu. International Journal of Wellbeing, 9(1), 61–82. 2019). Sisu captures the inner strengths and capabilities these women drew upon when challenges arose which enabled them to continue to move forward. The chapter draws on the data collected from Study C and discusses how sisu provides a lens through which to understand the determined persistence of these women, as a deeply personal, collective and complex experience.

AbstractAlthough there is a growing academic interest in xenophobia in South America (Chan & Strabucchi, Asian Ethnicity 22(2):374–394, 2020; Tijoux-Merino, Convergencia: Revista de Ciencias Sociales 20(61):83–104, 2013; Guizardi & Mardones, Estudios Fronterizos 21:1–24, 2020), research is incipient on Peru due, in part, to the recent changes in migration trends. Moreover, in the case of Peru, scholars have not explored how xenophobia and racism intersect and connect. Addressing this gap, this chapter examines xenophobia in Peru against the Venezuelan community from an institutional and social perspective, addressing how both perspectives are relational and self-sustaining in a context of racialization. We use a mixed methodology that combines literature and political-normative analysis with quantitative data analysis. We examine how the institutional xenophobia against Venezuelan migration in the country, expressed through legislation as well as informal and formal practices of exclusion, have portrayed migrants as invaders. We also argue that the structural and complex racialization that operates in the country is also nourished by a special hatred against the foreigner who threatens the fragile sense of nationhood in Peru. Thus, we observe the emergence of a feeling of Venezuelanphobia as a hatred towards everything that has to do with ‘the Venezuelan.’

ZusammenfassungDieses Kapitel widmet sich der Frage, wie familiale bzw. elterliche Ressourcen mit dem Unterstützungshandeln der Eltern sowie mit schulbezogenen Orientierungen und fachlichen Leistungen des Kindes zusammenhängen – jenen Größen, die sich beim Übertritt in die Sekundarstufe I im Sinne primärer Herkunftseffekte (vgl. Boudon, 1974) nebst den elterlichen Aspirationen als wichtigste Kriterien für die Entscheide der Akteure erwiesen haben (z. B. Ditton & Krüsken, 2006). Hierfür wird zuerst der kulturtheoretische Ansatz von Pierre Bourdieu (1984, 1996a) ins Zentrum gerückt, der u. a. postuliert, dass neben den ökonomischen auch die sozialen Handlungspotentiale der Familie, vor allem aber deren kulturelle Ressourcen – namentlich die bildungsbezogenen Praktiken – prädiktierten, wie erfolgreich sich das Kind in den Anforderungsstrukturen der Schule behaupten könne. Nach der Erörterung diesbezüglicher Befunde der empirischen Bildungsforschung und ausgehend vom Bourdieu’schen Konstrukt des Habitus richtet sich dann die Aufmerksamkeit auf die psychologischen Ressourcen der Eltern in Form bildungsbezogener Überzeugungen: Mit Hilfe des «Modells motivations- und leistungsbezogener Sozialisation im Elternhaus» von Eccles und Kolleg*innen (Simpkins et al., 2015a, S. 617; Wigfield, Eccles, et al., 2015, S. 22) wird der Einfluss solcher generalisierten Überzeugungen der Eltern im Zusammenspiel mit strukturellen Merkmalen der Familie auf das schulbezogene Motivierungshandeln herausgearbeitet. Das Kapitel schließt mit einer Übersicht über sozialstrukturelle Merkmale der Fallfamilien sowie über ausgewählte bildungsbezogene Überzeugungen der 20 beteiligten Elternteile.

This study is a major part of the dissertation research. It is focused on the development of shooting skills in young biathletes in a three-year training period. Specifically, the long-term development of the percentage success rate of prone and standing shooting in both training and races is described in study. It mentions marginally shooting skills such as the postural stability, the stability of aiming and triggering. The first part of our research, completed in 2017, brought findings that the relationship between exercise intensity and the biathlete’s postural stability exists, but following part of it, finalized in 2018, did not demonstrate the dependence of exercise intensity on the aiming stability and triggering. Initially, the study involved 23 young biathletes (13 girls, 10 boys). Whole research was completed by 19 biathletes (11 girls: age 17.8±0.64 years; 8 boys: age 17.4±0.72 years) after three years. The results of our current study are based on the records of shooting on metal targets that were created during each biathlon shooting training and all biathlon races of the participants in the three-year period. Only shooting with previous physical load was involved into results, shooting at rest was not included in the study. The results show the improvement of the percentage success rate in both prone and standing shooting in the three-year training period in both girl and boy groups and in both training and races (total percentage success rate = the average of the training and races percentage success rate – girls in prone: 2016/2017: 71.3%, 2017/2018: 75.5%, 2018/2019: 80.0%; girls in standing: 2016/2017: 61.8%, 2017/2018: 67.7%, 2018/2019: 73.4%; boys in prone: 2016/2017: 72.0%, 2017/2018: 72.9%, 2018/2019: 75.3%; boys in standing: 2016/2017: 57.6%, 2017/2018: 63.5%, 2018/2019: 67.7%). Girls are better shooters than boys in this research group. In general, the gradual improvement of percentage success rate in time is expected to occur in young biathletes that are in the intensive training process, but our study brings unique data of concretely values at this age of athletes that has not been known yet. The obtained data could be used by biathlon trainers to compare the current level of shooting skills at a given age of their young athletes. At the same time, a normative standard of biathlon shooting skills in a given age could be created in the case of gathering more data. That is one of the goals of the Czech Biathlon Union.

Calcium silicate hydrate (CSH) is a main component of cement-based material required for constructing the geological repository. As in many countries, since the repository in Japan is constructed below water table, we must consider the interaction of radionuclide with cement materials altered around the repository after the backfill. Using fluorescence emission spectra, so far, the authors have investigated the interaction of Eu(III) (as a chemical analog of Am(III)) with CSH gels formed with no dried process, considering a condition saturated with groundwater. However, in such fluorescence emission behaviors, a deexcitation process of OH vibrators of light water and a quenching effect caused by Eu-Eu energy transfer between Eu atoms incorporated in the CSH gel must be considered. This study examined the fluorescence emission behavior of Eu(III) sorbed on CSH gels formed with no dried process, by using La(III) (non-fluorescent ions) as a diluent of Eu(III). Furthermore, the CSH samples were synthesized with CaO, SiO2, and heavy water (D2O) as a solvent in order to avoid the obvious deexcitation process of OH vibrators of light water. This study prepared CSH samples with the Ca/Si ratio set to 1.6, 1.0, and 0.5. A 1 mM solution of a given combination of Eu(III) and La(III) (Eu(III) content: 100%, 67%, 50% or 33%) was added into CSH gel sample. The contact time-period of the CSH gel with the Eu(III)/La(III) solution was set to 60 days. In the results, the peak around 618 nm was split into two peaks of 613 nm and 622 nm in the cases of Ca/Si = 1.0 and 1.6. Then, the peak of 613 nm decreased with increment of Eu(III)/La(III) ratio. This means that the relative intensity of 613 nm is useful to quantify the amount of Eu(III) incorporated in CSH gel. Besides, the intensity peak of 584 nm decayed with increment of Eu/La ratio, suggesting a quenching effect due to Eu-Eu energy transfer. However, the decay behavior of the fluorescence emission did not depend on the Eu/La concentration ratio. That is, such a quenching effect is neglectable. Additionally, the low Ca/Si ratio samples underwent slow attenuation of fluorescence and showed profiles similar to those of high Ca/Si ratio samples. Therefore, low Ca/Si ratio samples also include the reaction forming a complex on the surface of CSH gel with Eu(III). In other words, even if Ca/Si ratio is lower than 1.0, CSH gels would retard the migration of radionuclides released from the repository.

AbstractThe urgency for developing a circular economy is growing, and more and more companies and organisations are concerned with the importance of adapting their business to fit a changing economy. However, many analyses on the circular economy are still rather abstract and there is a lack of understanding about what circularity would mean for specific industries. This insufficient insight especially seems to be apparent in the building and construction sector. Besides, the building and construction sector is responsible for a major part of energy use and emissions. To tackle the issue of insufficient insight into the business consequences of circular devlopments, further research is necessary. Therefore, we propose to collaborate on a research project that aims to provide a more detailed level of analysis. The goal is to identify drivers and barriers to make better use of materials in the building and construction sector. This further research would benefit from an international collaboration between universities of applied sciences and industry from different European countries. An additional benefit of the applied orientation would be the relevance for professional education programmes. References CBS, PBL & Wageningen UR. (2017).

Introdução: Para prevenir as infecções sexualmente transmissíveis (IST), a Organização Mundial da Saúde (OMS) destaca a importância da educação sexual. Nesse contexto, as campanhas representam canais poderosos para promover conhecimento à população. Objetivo: Descrever as campanhas de prevenção ao HIV, às IST e às hepatites virais implementadas pelo Ministério da Saúde (MS) do Brasil no período de 1998 a 2020, enfatizando as mídias utilizadas. Métodos: Trata-se de uma pesquisa de caráter descritivo e documental, realizada em parceria entre a Universidade de Brasília (UnB) e a Universidade Católica de Brasília (UCB). Os dados foram coletados no site do Departamento de Condições Crônicas e Infecções Sexualmente Transmissíveis (DCCI). Para cada campanha, os seguintes itens foram avaliados: (1) ano de publicação; (2) nome da campanha; (3) tema central; (4) público-alvo; (5) tipos de mídias utilizadas; e (6) outras informações relevantes. Resultados: O MS produziu 82 campanhas, das quais algumas abordaram mais de um tema. Foram feitas 61 campanhas sobre HIV/AIDS, sendo 18% para a população prioritária e 12% para a população-chave. Não houve campanhas em 2020. Para as demais IST, foram produzidas 23 campanhas no período. Os anos sem campanhas foram 1998, 2003–2007, 2011 e 2020. Para hepatites virais, houve apenas 12 campanhas, nos anos de 2009–2011, 2013, 2015, 2017 e 2020. Foram utilizadas mídias eletrônicas (TV, rádio e cinema) e impressas (fôlder, cartaz, outdoor, cartilha, manual e adesivos), sendo o cartaz o mais utilizado em todo o período de análise. Conclusão: As campanhas reforçaram principalmente a importância quanto ao uso do preservativo. Em 2020, durante o isolamento em razão da COVID-19, o consumo de mídia e informação aumentou, porém o MS não lançou campanhas sobre HIV/AIDS e as demais IST. Por fim, percebe-se que, para atingir os jovens em maior quantidade, o MS deve focar nas mídias digitais.

Reciprocating compressors are extensively used on high pressure and critical applications in all industries. These equipment needs through review of design of various components for a failsafe design. API-618 specifies various details about construction of various components, but due to OEM design by compressor vendor, proper review is not done or due to cost economic of equipment these are not given importance. There are many examples when accident took place when these issues were ignored or correct assembly procedure for assembly of components is not followed and there were mistakes in design of piping system. In this paper, some of such cases are discussed and improvements are suggested for preventing any safety incidents. The issues described are designs of unloaders and venting system, unloader and vent piping, cylinder tap off connections, end clearance pocket unloaders, distance piece and crank case venting system, purge system for motors. One of the risks with valve unloaders is the contamination of the instrument air with flammable gas specially on high pressure application. The instrument air may get contaminated with hydrocarbon if unloader leaking from stem and leak off gas tubing which is connected to flare may get interchanged with the instrument air connection. The same mistake if not noticed & compressor started, it may lead to the incident where compressor can show showed a strange vibration pattern, and instrument air header may get contaminated with hydrocarbon gases. Another issue is crank case pressurisation due to improper venting system which can lead to pressurisation of crank case, failure of oil seals leading to flywheel end bearing failures. Further checking for finding reasons of crank case pressurisation, it is observed that excessive rod packing leaks results from incorrect leveling of compressor, distance and cylinders. Motor purge system is one of the essential requirements for starting large reciprocating compressors; mistake in design/fabrication of vent system may create unsafe condition leading to explosion in motor. All issues have been discussed in paper and various solutions and fail safe design have been suggested to improve safety and reliability. The studies also indicates that proper start up procedure and follow up of correct checklists during overhauling and start up can eliminate/ identify such mistakes.

In the Hohlenstein-Stadel Cave in 1939 excavators uncovered nearly 200 mammoth ivory fragments, which were refitted as a therianthrope figurine with the head and torso of a cave lion but with the legs of a human being. It was thus named the Lion Man. During recent excavations in the Stadel Cave between 2008 and 2013, a stratigraphic sequence was discovered that extended from the Middle Palaeolithic to the Aurignacian. It became clear that the location of the Lion Man during the excavations of 1939 corresponded to layer Au of the recent 2008-2013 excavations part of the excavation back dirt from 1939 was also uncovered. Here, 575 fragments of mammoth ivory were found that partially belonged to the Lion Man figurine that was carved from a complete tusk. In 2012/2013 the Lion Man was therefore newly restored. The figure was completed to the greatest possible extent. It became apparent that the Lion Man represents a male. We also obtained new perpectives on the position and the sinistral ornamentation of the figurine. The snout, the back and the right side were refitted and the Lion Man also gained volume due to the refitted pieces. New insight underlines the intentional deposition of the formerly complete figurine during the Aurignacian. Wehrberger, K. (Ed.) (2013). The Return of the Lion Man. History Myth Magic.

Background: Chronic migraine is a neurological disorder described as refractory to preventive treatments. Based on the PREEMPT study, the National Institute for Health and Clinical Excellence (NICE) and the FDA approved, in 2010, the use of Botulinum Toxin type A (BoNT/A) to treat refractory chronic migraine. Objectives: To review the effectiveness of the use of BoNT/A in the treatment of refractory migraine. Methods: Bibliographic review based on PubMed database, using the descriptors “migraine” and “botulinum toxin”. Clinical trials, meta-analyzes and randomized controlled tests, from the last five years, were defined as inclusion criteria. Results: Sanz et al., (2016) infiltrated BoNT/A in 69 patients - mean age 43 years old, 88.4% women, mean infiltration rate was 2,0. The reduction of headache days and pain intensity was 48.5% and 20.5%, respectively, both statistically significant (p <0.006). Ion et al., (2018) intervened 61 patients - mean age 50 years old, 87% women, mean infiltration of 3.5. 73% showed a reduction greater than 50% for the frequency of migraine episodes, 48% for headache days and 48% for drug use. Dodick et al., (2019) applied BoNT/A in 688 patients - 696 received placebo. The severity and frequency of pain showed a statistically significant reduction (p < 0.001) after the first week of treatment in relation to the control group. Conclusions: The use of BoNT/A to treat refractory chronic migraine proves to be effective, although there is need for studies with larger samples to ensure its effectiveness.

This document details trends in remittances to Latin America and the Caribbean in 2011, paying particular attention to the effects of recent economic growth. Over the course of 2011, remittance flows to Latin American and Caribbean (LAC) showed signs of a solid recovery, reaching growth rates close to those recorded before the start of the global economic crisis. Since the last quarter of 2008, the increases in unemployment rates in traditional sending countries like the United States, Spain, and Japan, and the ensuing drops in incomes among LAC migrants had caused an unprecedented decline in the volume of remittances sent to the region. In 2010, remittances to LAC showed signs of stabilization, finishing on a positive growth trend that resulted in an annual volume that was slightly higher than the previous year. In 2011, the countries in the region received a total of US$ 61 billion in remittances, which represents an increase of 6% over the previous year.

Rocky Mountain National Park (RMNP) developed the Elk and Vegetation Management Plan (EVMP) to address well-documented declines in the ecological condition of aspen stands and riparian communities from high levels of elk herbivory. The EVMP aims to reduce the impacts of elk on vegetation and restore the natural range of variability in the elk population and affected plant communities, including preventing the loss of aspen clones within high elk-use areas, restoring montane riparian willow cover and height within suitable habitat, and reducing of levels of elk grazing on herbaceous vegetation. The EVMP described a range of management actions including reductions in the size of the elk herd and the installation of fencing to reduce herbivory levels and facilitate recovery in degraded communities. The EVMP established a monitoring protocol in focal communities to assess progress towards these vegetation goals and facilitate adaptive management. RMNP has collected data quantifying biomass offtake in upland herbaceous and riparian communities, willow height and cover, and aspen stand structure and regeneration periodically since implementation of the plan began in 2008. This report summarizes the results of analyses of EVMP data collected from 2008–2018, the last year comprehensive measurements were made. The EVMP was developed with a focus on the primary elk winter range in the upper montane zone on the east side of RMNP. The plan distinguishes core elk winter range, where elk concentrate during winter, and noncore winter range areas that typically have less elk use. Data were also collected in the Kawuneeche Valley in the headwaters of the Colorado River on the west side of the park, an area supporting extensive wet meadows and areas once dominated by willow. Data were also collected to investigate the effects of wildland fires that burned through the winter range in 2012 to determine the potential for using fire as a management tool to achieve EVMP goals. The overwintering elk population in the park has declined, from its peak of 1,500 animals in 2001, and over the course of EVMP implementation, from 614 animals in 2009 to 124 animals in 2019. Declines in the overwintering elk population may be best explained by increased cow elk harvest outside of the park, and, most notably, by a change in seasonal migration patterns and habitat use that have elk moving to lower elevation wintering areas following the fall rut. In sites in aspen communities, stand structure was changed little or declined across sampling periods in unfenced plots with continued patterns of little regeneration and recruitment and steady progression toward stands dominated by large-diameter trees. However, there was a progression towards taller sapling heights inside fenced plots and recruitment of small diameter tree-sized stems. Fencing had large and positive effects on aspen stand structure, with different patterns observed in fenced and unfenced core winter range and noncore winter range. Increased recruitment was observed across the winter range but occurred mainly inside fenced plots. Aspen stem counts varied between time periods and in relation to wildfire, with fenced and burned plots on the core winter range having higher stem counts by 2018 than unfenced and unburned plots. Willow height and cover increased over time in sampled sites, but positive trends were generally restricted to sites in fenced areas. Willow height also increased on noncore (all unfenced) winter range sites. Willow in unfenced core winter range sites had only minor increase in height from baseline (2008 for most sites) to 2018, but willow in fenced plots had greater height increases over the same time period. Noncore winter range willow sites had modest height increases over the 10-yr period. Mean willow cover increased nearly 5-fold compared to baseline conditions within the core winter range fenced areas and roughly 1.5-fold in noncore winter range. Willow cover was greater in unfenced than fenced plots at baseline, but the pattern was reversed in 2013 and 2018. The highest cover occurred in 2018 in fenced core winter range plots (mean = 70.8%) and unfenced noncore winter range plots (mean = 68.6%). Mean cover increased from 14.6% at baseline to 25.3% in 2013 and 70.8% in 2018 in fenced core winter range plots. Mean willow cover changed little in unfenced core winter range plots between baseline and 2018, although the range of cover values increased over time, and willow cover increases were modest in the noncore winter range. Fencing reduced or eliminated browsing from plots located inside fences, but offtake varied widely among unfenced plots. Patterns of willow browse intensity differed management subgroups (e.g., core and noncore winter range), and generally showed a downward trend between baseline and 2018 measurements. Herbaceous offtake in upland communities was measured in the first sample period (baseline–2013) to assess levels of grazing on herbaceous vegetation, however it was determined that the associated EVMP objectives had been achieved so measurements were discontinued after 2013. Continued monitoring of upland shrubs indicated no shift from herbaceous dominated to shrub dominated communities after 2013. Noncore upland plots had higher shrub cover than core winter range plots across all time periods, but most differences between year and core/noncore had low probability of effect. Cover for individual species varied over time and winter range plots. Moose presence has increased in winter range aspen and willow sites over the past decade, while beaver presence at our monitoring sites has decreased. Results indicate that RMNP is making progress toward the vegetation objectives set out in the EVMP, however positive trends were most pronounced in plots protected from ungulate herbivory through fencing. Aspen recruitment was greatest in fenced plots. Likewise, trajectories of willow height and cover were positive in fenced winter range plots. Results demonstrate that fencing is an effective means of improving condition in aspen and willow habitats. Changes outside the fences were slower and less pronounced than inside the fences, however, the positive (if small) increases in willow height and cover and aspen regeneration as well as decreases in upland herbaceous offtake, indicate that decreased wintering elk populations are also contributing to improvement of habitat conditions on the elk winter range. In the Kawuneeche Valley, which has not traditionally been heavily used by overwintering elk but does experience summer elk and moose use, poor and declining habitat condition were recorded in unfenced willow and aspen sites.

Introducción: la prevalencia de defectos congénitos en el mundo oscila entre 2 y 3 %, ocupando una posición importante dentro de las causas de carga de la enfermedad a nivel mundial. La vigilancia de los defectos congénitos es un componente esencial para orientar acciones que permitan prevenir y controlar este tipo de eventos de alta mortalidad y complicaciones. El objetivo del estudio fue caracterizar el comportamiento de los defectos congénitos en Colombia durante el 2019. Materiales y métodos: estudio de tipo descriptivo transversal. La población correspondió a los casos de defectos congénitos detectados al nacimiento o hasta un año de vida notificados al Sistema de Vigilancia epidemiológica nacional (Sivigila). El plan de análisis se realizó mediante estadística descriptiva. Resultados: se notificaron 7 610 casos de defectos congénitos mayores, con una prevalencia de 120,1 casos por cada 10 000 nacidos vivos (NV). Según la edad materna, a partir de los 30 años la prevalencia incrementa y alcanza su mayor valor en mujeres de 45 y más años con 357,5 por 10 000 NV . Las malformaciones congénitas que se notificaron con mayor frecuencia fueron las malformaciones del sistema osteomuscular, principalmente polidactilia, gastrosquisis y talipes equinovarus Conclusión: se encontró la prevalencia nacional dentro de las estimaciones realizadas a nivel mundial. Según la edad materna, diversos estudios han demostrado la relación entre edad materna aumentada y riesgo de defectos congénitos cromosómicos. La polidactilia presenta una prevalencia por encima de los reportes latinoamericanos del ECLAMC, respaldando la hipótesis de la presencia de un comportamiento inusual en el país para este tipo de defecto.

The Browns Hole quadrangle is in Weber and Cache Counties of northern Utah and covers the eastern part of Ogden Valley, a rapidly developing area of the Wasatch Range. The Middle and South Forks of the Ogden River bisect the quadrangle and are important watersheds and recreational areas to the communities of Ogden Valley and the Wasatch Front. The towns of Huntsville and Eden are just west of the quadrangle, unincorporated communities with year-round residents are present throughout the quadrangle, and numerous summer-cabin communities are present in the eastern part of the quadrangle. A portion of Powder Mountain ski resort, which draws year-round visitation and recreation, is present in the northwest corner of the quadrangle. The quadrangle contains the Willard thrust, a major thrust fault with approximately 30 mi (50 km) of eastward displacement that was active during the Cretaceous-Eocene Sevier orogeny (Yonkee and others, 2019). In the quadrangle, the Willard thrust places Neoproterozoic through Ordovician strata in the hanging wall over a fault-bounded lozenge of Cambrian strata and footwall Jurassic and Triassic strata (see cross section on Plate 2). Neoproterozoic strata comprise a succession of mostly clastic rocks deposited during rifting of western North America and breakup of the supercontinent Rodinia (Yonkee and others, 2014). These rocks include the Cryogenian-age Perry Canyon and Maple Canyon Formations, and the Ediacaran-age Kelley Canyon Formation, Papoose Creek Formation, Caddy Canyon Quartzite, Inkom Formation, Mutual Formation, and Browns Hole Formation. The Browns Hole Formation is a sequence of interbedded volcaniclastic rock and basalt lava flows that provides the only radiometric age control in the quadrangle. Provow and others (2021) reported a ~610 Ma detrital apatite U-Pb age from volcaniclastic sandstone at the base of the formation, Crittenden and Wallace (1973) reported a 580 ± 14 Ma K-Ar hornblende age for a volcanic clast, and Verdel (2009) reported a 609 ± 25 Ma U-Pb apatite age for a basalt flow near the top of the formation. Cambrian strata in the hanging wall include a thick basal clastic sequence (Geertsen Canyon Quartzite) overlain by a thick sequence of interbedded limestone, shale, and dolomite (Langston, Ute, and Blacksmith Formations). Hanging wall rocks are deformed by Willard thrust-related structures, including the Browns Hole anticline, Maple Canyon thrust, and numerous smaller folds and minor faults. Footwall rocks of the Willard thrust include highly deformed Cambrian strata within a fault-bounded lozenge exposed in the southern part of the quadrangle, and Jurassic and Triassic rocks exposed just south of the quadrangle. The Paleocene-Eocene Wasatch Formation unconformably overlies older rocks and was deposited over considerable paleotopography developed during late stages of the Sevier orogeny. The southwest part of the quadrangle is cut by a southwest-dipping normal fault system that bounds the east side of Ogden Valley. This fault is interpreted to have experienced an early phase of slip during local late Eocene to Oligocene collapse of the Sevier belt and deposition of volcanic and volcaniclastic rocks (Norwood Tuff) exposed west of the quadrangle (Sorensen and Crittenden, 1979), and a younger phase of slip during Neogene Basin and Range extension (Zoback, 1983). Lacustrine deposits and shorelines of Pleistocene-age Lake Bonneville are present in the southwest corner of the quadrangle near the mouth of the South Fork of the Ogden River and record the highstand of Lake Bonneville (Oviatt, 2015). Pleistocene glacial deposits, present in the northwest corner of the map, are likely related to the Pinedale glaciation, commonly expressed by two moraine building episodes in the Wasatch Range (Quirk and others, 2020). Numerous incised alluvial deposits and geomorphic surfaces are present along major drainages and record pre- and post-Lake Bonneville aggradational and degradational alluvial and colluvial sequences. Mass-movement deposits, including historically active landslides, are present throughout the quadrangle. Crittenden (1972) mapped the Browns Hole quadrangle at 1:24,000 scale, which provided an excellent foundation for the general stratigraphy and structure, but the 1972 map lacked important details of unconsolidated surficial units. As part of 1:62,500 scale mapping of the Ogden 30'x60' quadrangle, Coogan and King (2016) updated stratigraphic nomenclature, revised some contacts, and added more details for surficial units. For this map, we utilized new techniques for data acquisition and analysis to delineate surficial deposits, bedrock contacts, and faults more accurately and precisely. Mapping and field data collection were largely done in 2021–2022 using a combination of GPS-enabled tablets equipped with georectified aerial imagery (U.S. Department of Agriculture [USDA] National Agriculture Imagery Program [NAIP], 2009), orthoimagery (Utah Geospatial Resource Center [UGRC] State Geographic Information Database, 2018b, 2018c; 2021a, 2021b), and lidar data (UGRC State Geographic Information Database, 2006; 2011; 2013–2014; 2018a), previously published geologic maps, topographic maps, and applications for digital attitude collection. We also used hand-held GPS units, Brunton compasses, and field notebooks to collect geologic data. Field data were transferred to a Geographic Information System (GIS), where the map was compiled and completed.

The objective of the PRCI MATR-3-11 Composite Repair Load Transfer Study was to evaluate the effect of internal pipe pressure during installation of composite reinforcement systems. Historically, there has been little work evaluating the effect of internal pressure during installation, even though almost all composite installations on transmission pipelines are performed with internal pressure present in the pipe. The focus of this work was specifically limited to reinforcement of pipelines containing simulated corrosion anomalies. Five composite repair technologies from four composite manufacturers were evaluated in this study including: � Western Specialties Ultra-Wrap (E-glass/epoxy) � Western Specialties Composi-Sleeve (steel sleeve with E-glass overwrap) � Citadel (carbon fiber/epoxy) � Furmanite (carbon fiber/epoxy) � NRI Steel Wrap (high-modulus carbon fiber/epoxy) This study used full-scale testing to analyze the load transfer between the composite repair and pipe with internal pressure present during installation and whether this condition impacts the reinforcement provided by the composite repair system. The anomaly configuration evaluated in this study was a machined corrosion defect simulating 50% wall loss in 12.75-inch x 0.375-inch, Grade X42 pipe material. For safety, internal pressure during installation was limited to 50% SMYS (1,236 psig) for the corrosion samples. The composite repairs for the corrosion defects were installed at internal pressure levels of 0 psig, 25% SMYS (618 psig), and 50% SMYS (1,236 psig). Following repair installation, the reinforced full-scale samples were burst tested or pressure cycled to failure to evaluate the repair's performance. Results indicated that, in general, internal pressure during installation did not significantly impact the ability of the composite systems to reinforce the corrosion anomalies evaluated in this study when installed at or below 50% SMYS. Installation pressures up to 50% SMYS had no noticeable effect on the burst pressure of the corroded sample composite repairs, and the burst pressure of all repairs were equivalent to pressure levels for an unreinforced, undamaged pipe. Also, all repairs failed at approximately the same average burst pressure, regardless of installation pressure. Furthermore, installation pressures up to 50% SMYS had little or no noticeable effect on the fatigue life of reinforced corrosion samples; all sample repairs reached the target runout of 250,000 cycles. Observations from the burst testing suggested that loads from the corroded region were not transferred to the composite repair until the corroded region began to yield, regardless of the pressure at which the composite was installed (applicable for installation pressures at or below 50% SMYS and a corrosion depth of 50%). The results and findings of this study provide valuable information to the pipeline industry for addressing an issue of significant interest for many years, and one not previously addressed in a comprehensive manner via full-scale testing. An important observation from this study is that the performance of composite repairs made on corrosion defects does not appear to be appreciably reduced when internal pressures up to 50% SMYS are present during installation.

A full-scale burst test program was devised and agreed with the PRCI Materials Technical Committee Ad Hoc group. The work was undertaken over a two year period, 2003 and 2004. Due to budget constraints, only one pipe diameter and material was chosen for the test program. This was 24� (610 mm) outside diameter (OD) by 7.9 mm wall thickness, welded ERW steel linepipe of material API 5L grade B/X42. The criterion that defects separated by a distance of 6t or less will interact is over conservative. New rules for interaction, derived using non-linear finite element analyses and validated using full scale burst testing, have been derived for closely spaced metal loss interacting defects in pipelines. New, robust interaction rules for assessing corrosion metal loss defects in pipelines have been formulated for use by the pipeline industry.

This paper presents a new data fusion multiscale observation product (MOP) for flood emergencies. The MOP was created by integrating multiple sources of contributed open-source data with traditional spaceborne remote sensing imagery to provide a sequence of high spatial and temporal resolution flood inundation maps. The study focuses on the 2015 Memorial Day floods that caused up to US$61 million of damage. The Hydraulic Engineering Center River Analysis System (HEC-RAS) model was used to simulate water surfaces for the northern part of the Trinity River in Dallas, using reservoir surcharge releases and topographic data provided by the US Army Corps of Engineers. A measure of fit assessment is performed on the MOP flood maps with the HEC-RAS simulated flood inundation output to quantify spatial differences. Estimating possible flood inundation using individual datasets that vary spatially and temporally allow an understanding of how much each observational dataset contributes to the overall water estimation. Results show that water surfaces estimated by MOP are comparable with the simulated output for the duration of the flood event. Additionally, contributed data, such as Civil Air Patrol, although they may be geographically sparse, become an important data source when fused with other observation data.
