Abstract:
Sugarcane plant samples affected by the disease pokkah boeng were collected from the major sugarcane producing areas in Iran. Fifty isolates of Fusarium verticillioides were recovered from diseased sugarcanes. Results of pathogenicity tests revealed that all isolates were pathogenic to sugarcane. Four hundred and eighty-five nitrate non-utilising mutants were generated from F. verticillioides isolates. Media used for nit mutant generation included potato dextrose agar, minimal medium and Czapeck agar amended with 1.8%, 2%, 2.5%, and 3% potassium chlorate. Nit mutants were divided into three phenotypic (nit1, nit3, and nitM) classes based on their growth on different nitrogen sources in the culture media. Among the isolates tested, 280, 115 and 90 nit1, nit3, and nit M were generated, respectively. Nit mutants were used to force the heterokaryon formation to determine the distribution of VCGs and their relation to pathogenicity and geographic origin. Forty-eight VCGs of F. verticillioides were isolated from sugarcane. Forty-six of the VCGs were represented by a single isolate, whereas the remaining two comprised two isolates. None of the VCGs was common.

Abstract:
Evolution of galaxies is one of the most important topics in astronomy to understand how the universe has been evolving. In particular, galaxy groups are important because they are the observable equivalent of dark matter (DM) haloes, and thus offer a direct insight into the physics that has occurred in the DM haloes in the Universe up to the present day. Isolated galaxies are crucial for studying intrinsic and secular processes able to affect the structure, morphology, and dynamics of galaxies for obtaining clear relationships and correlations to be confronted with the model predictions. The main goal of this work is to characterize the GAMA G3Cv1 galaxy groups catalogue and the UNAM-KIAS catalogue of isolated galaxies by one of the most important statistical studies, the galaxy Luminosity Function (LF), that helps to constrain the models of formation and evolution of galaxies. LFs have been estimated for galaxies in groups and isolated galaxies. The LF for groups has been characterized by the physical properties of the groups (mass and velocity dispersion), the photometry (colour), the morphological type and eleven wavelengths from the far infra-red to the ultra violet. The LF estimated for the isolated galaxies is characterized by morphology and the colour in the five SDSS bands. The results obtained constrain more effectively the formation and evolution models of the universe than previous samples. The differences between both catalogues are presented in the conclusions. Additionally, the galaxy morphology is one of the no well understood problems in the galaxy evolution process to support the hierarchical model of formation of large objects. In this work, a classification based on the colour and concentration of light was considered. However, due to the low resolution of the images, the confidence of this classification was only ~60%.

Abstract:
The purpose of this study is to examine the meeting between children in cults and personnel in Swedish schools and Child Protective Services (CPS). Furthermore, the study investigates whether children in cults who are being mistreated receive the help and attention they need from school and the CPS. This study has a qualitative research approach. Five semi-structured interviews with former cult members and professionals who have worked with children in cults were conducted. The interviews were supplemented with a content analysis of two autobiographies written by former cult members. The theory chosen was the general systems theory with the aim to use it as a tool to further understand how cults work as a system and how it affects the children in them. The results show that children who live in cults can be exposed to physical and mental abuse. Furthermore, it is difficult for professionals to identify children that have experienced abuse, due to the cults view of and approach to people outside their own community. Lack of knowledge regarding how to recognize these children in cults that have experienced abuse and non-existent training in how to handle said cases is one reason for why many children have been overlooked.

The research analyzed the role of primary teachers in the early decades of the Republic, specifically those who have taught in the Vale do Paraíba between the years 1889 to 1920, characterized by the expansion of isolated schools period, the emergence of the first school groups and the appointment and circulation teachers of these educational institutions. We chose a selection of subjects that, somehow, gained prominence in the scope of the school inspection reports and documents prepared by the directors of the school groups and those produced by teachers in disciplinary proceedings and periodical press. The main objective was to evaluate how these professionals have articulated given the particularities related to these schools in their educational, cultural, social and political aspects models, in order to track which teachers developed these understandings of the state and his own profession, their reactions bureaucratic and pedagogical norms and their views of students. As theoretical and methodological tool we highlight the contributions of Jean-François Sirinelli with its concepts of route generation and sociability as a way to analyze the intellectual (teacher) as a political actor, and experience of E.P. Thompson, in order to understand the actions and conditioned representations of these teachers that allowed them context. Thus, it was possible to assess how the hierarchical relationships with the state, and their social integration, ultimately influence the performance and careers of these teachers
A pesquisa analisou a atuação de professores primários nas primeiras décadas da República, especificamente aqueles que lecionaram no Vale do Paraíba paulista entre os anos de 1889 a 1920, período caracterizado pela ampliação de escolas isoladas, o surgimento dos primeiros grupos escolares e a nomeação e circulação de docentes nestas instituições de ensino. Optou-se por uma seleção de sujeitos que, de alguma forma, ganharam destaque no escopo dos relatórios da inspeção escolar e nos documentos elaborados pelos diretores dos grupos escolares e naqueles produzidos pelos próprios professores em processos disciplinares e na imprensa periódica. O principal objetivo foi avaliar como estes profissionais se articularam diante das particularidades relacionadas a estes modelos escolares em seus aspectos pedagógico, cultural, social e político, de forma a rastrear quais compreensões que estes docentes elaboraram do Estado e de sua própria profissão, suas reações diante das normatizações burocráticas e pedagógicas e suas visões do alunado. Como ferramenta teórico-metodológica destacam-se as contribuições de Jean- François Sirinelli com seus conceitos de itinerário, geração e sociabilidade como forma de analisar o intelectual (professor) como ator político, e de experiência de E. P. Thompson, a fim de compreender as ações e representações condicionadas destes professores que o contexto lhes permitia. Com isso, foi possível avaliar de que maneira as relações hierárquicas com o Estado, além de sua inserção social, acabaram por influenciar na atuação e na carreira destes professores

Abstract:
Cryptococcus neoformans is an encapsulated yeast responsible for severe meningoencephalitis. The importance of epidemiological studies on cryptococcosis has increased since the beginning of the AIDS epidemic. C. neoformans exists in two varieties containing four serotypes, C. neoformans var. neoformans (serotypes A and D) and C. neoformans var. gattii (serotypes B and C). Locally C. neoformans var. neoformans has been associated with pigeon feces during those months having an average temperature of 64.2°F j(17.8°C) and above. Clinical and environmental isolates of C. neoformans obtained from regional hospitals and environmental samplings, respectively, have been grouped into their variety status utilizing canavanine-glycine-bromthymol blue agar. Polyclonal antisera against C. neoformans serotypes A, B, C and D were isolated from challenged rabbits. Serotyping C. neofromans isolates using the polyclonal antisera resulted in 57% (20 of 35) of the serotypes confirmed with a direct immunofluorescent assay utilizing a single monoclonal antibody (E1). Data from the immunofluorescence assay suggest all C. neoformans obtained from regional hospitals (26 of 26) and those isolated from the environment (9 of 9) belong to the A serotype group. These data have provided information leading to the origin of infection for cryptococcosis in our region, which may be beneficial to immunocompromised individuals.

Abstract:
In this study influences of vertical ground motion on seismically isolated bridges were investigated for seven different earthquake data. One assessment of bearing effect involves the calculation of vertical earthquake load on the seismically isolated bridges. This paper investigates the influence of vertical earthquake excitation on the response of briefly steel girder composite bridges (SCB) with and without seismic isolation through specifically selected earthquakes. In detail, the bridge is composed of 30m long three spans, concrete double piers at each axis supported by mat foundations with pile systems. At both end of the spans there exists concrete abutments to support superstructure of the bridge. SCBs which were seismically isolated with nine commonly preferred different lead&
#8208
rubber bearings (LRB) under each steel girder were analyzed. Then, the comparisons were made with a SCB without seismic isolation. Initially, a preliminary design was made and reasonable sections for the bridge have been obtained. As a result of this, the steel girder bridge sections were checked with AASHTO provisions and analytical model was updated accordingly. Earthquake records were thought as the main loading sources. Hence both cases were exposed to tri&
#8208
axial earthquake loads in order to understand the effects under such circumstances. Seven near fault earthquake data were selected by considering possession of directivity. Several runs using the chosen earthquakes were performed in order to be able to derive satisfactory comparisons between different types of isolators. Analytical calculations were conducted using well known structural analysis software (SAS) SAP2000. Nonlinear time history analysis was performed using the analytical model of the bridge with and without seismic isolation. Response data collected from SAS was used to determine the vertical load on the piers and middle span midspan moment on the steel girders due to the vertical and horizontal component of excitation. Comparisons dealing with the effects of horizontal only and horizontal plus vertical earthquake loads were introduced.

Full text
Abstract:
Simplified methods of analysis described in codes and specifications for seismically isolated structures are always used either directly in special cases or for checking the results of nonlinear response history analysis (RHA). Important predictions for seismically isolated structures by simplified methods are the maximum displacements and base shears of the isolation system. In this study, the maximum isolator displacements and base shears determined by nonlinear RHA are compared with those determined by the equivalent lateral force (ELF) procedure in order to assess the accuracy of the simplified method in the case of bi-directional excitations with near-field characteristics. However, although there are currently many methods for ground motion selection and scaling, little guidance is available to classify which method is more appropriate than the others in any applications. Features of this study are that the ground motions used in analysis are selected and scaled using contemporary concepts and that the ground excitation is considered biv directional. The variations in response of isolated structures due to application of ground motions uni-directionally and bi-directionally are also studied by employing a scaling procedure that is appropriate for the bi-directional analysis. The proposed new scaling methodology is an amplitude scaling method that is capable of preserving the horizontal orthogonal components and it is developed especially for dynamic analysis of isolated structures. Analyses are conducted for two different symmetric reinforced concrete isolated structure for two different soil conditions in structural analysis program SAP2000. Effect of asymmetry in superstructure on isolator displacement is also investigated with further analyses considering 5% mass eccentricity at each floor level. Furthermore, once the significance of the orthogonal horizontal component on the response of isolation system is shown, the biaxial interaction of hysteretic behavior of lead rubber bearings is implemented in OpenSees by developing a subroutine which was not readily available.

Abstract:
In group-structured populations in which some other assumptions are satisfied, kin and group selectionist methods provide formally equivalent conditions for change. However, this only shows an equivalence between two statistical methodologies, and this is compatible with there being a real, causal distinction between kin and group selection processes. This chapter pursues a Hamilton-inspired, population-centred approach to drawing that distinction, on which the differences between kin and group selection are differences of degree in the structural properties of populations. The relevant properties are K, the overall degree to which genealogical kin interact differentially, and G, the overall degree to which the population contains stable, internally integrated, and externally isolated social groups. A spatial metaphor (‘K-G space’) provides a useful framework for thinking about these differences.

Abstract:
The human propensity for religious behavior and, eventually, religious organization is the by-product of natural selection working on the neuroanatomy of low-sociality and non-group-forming hominins to become more social and group oriented as a necessary strategy for survival on the African savanna. Using cladistic analysis to determine the behavioral and organizational propensities of the last common ancestor to present-day great apes and humans’ hominin ancestors, while at the same time engaging in comparative neuroanatomy of extant great-ape and human brains, the neurological basis of religion is isolated. Religion emerged under early selection pressures to make hominins more social and able to form stable groups. From the combination of dramatically increased emotionality and cognitive functioning, the transition from Homo erectus to Homo sapiens approximately 300,000 year ago created the neurological platform for religious behaviors among early humans.

Abstract:
The effects of alkyl group size on nitric oxide and soot emissions in small esters was investigated using a multi-element diffusion burner (a Hencken burner) and pool fires at atmospheric pressure. The esters were chosen to examine chemical structure characteristics, e.g. carboxylic acid length, while holding other parameters constant (molecular weight, and C:H:O ratio), to determine the effects of various structural parameters on the particulate matter and NO emissions. The esters were chosen to vary alkyl chain length from one to four carbons in both their alcohol and carboxylic acid groups with the largest ester chosen containing 5 carbons in total. Increasing the carbon content increased the relative sooting tendencies of the esters. Within the isomer pairs considered, the sooting tendency was higher for compounds with longer alcohol groups compared to longer carboxylic groups. Although the NO results were convolved with temperature and structural effects are not isolated, the NO emissions were significantly affected by the addition of the esters to a baseline methane flame.

Abstract:
The base isolation, a kind of passive control technology, has been proved as a very efficient way to ensure the safety of a structure during severe earthquakes both from theoretical study and experimental effort. In general, the base isolation can be classified into two groups, which are sliding type and elastomeric type isolator. In this study, a new base isolator called as Multiple Friction Pendulum System (MFPS) has been proposed. The lubricant material, articulated slider and doubled concave sliding interfaces of MFPS are quite different from that proposed by V. Zayas in 1987. In this study, the MFPS isolator has been equipped beneath each column of a three-story structure at the National Center for Research on Earthquake Engineering to demonstrate its seismic resistance capability. The experimental results from shaking table tests of the 1940 El Centro, 1995 Kobe and 1999 Chi-Chi earthquake show that the proposed isolator can reduce the undesirable seismic response of the structure by lengthening the fundamental period of the structure during earthquakes. The experimental results indicate that the acceleration response of each floor can be lessened significantly as compared with those of the bare structure, and that the stress responses of structural components are limited in the certain range during severe earthquakes. Furthermore, the residual displacements of base isolators are negligible. Therefore, it is shown evidently that the proposed isolator can always bring the base-isolated structure to its initial position after an earthquake. Based on the previous observations, the proposed isolator can be adopted as an effective tool for upgrading the seismic resistibility of a structure. A finite element formulation for the MFPS is also proposed to simulate its mechanical behavior during earthquakes.

Abstract:
Disc degeneration is a multifactor phenomenon. It has been found that intervertebral disc (IVD) cells respond to such factors as pH, osmotic pressure, genetic factors, and mechanical loading (Guilak, 1999). During daily activities the human intervertebral disc is exposed to oscillatory hydrostatic loads that produce pressures >2MPa in vivo (Nachemson, 1964 and 1979). It is known that dynamic loads with critical frequencies close to that of the in vivo human spine resonant frequency (4–5 Hz) have a destructive effect on disc tissue properties (Pope, 1993). Whether this destructive effect is purely mechanical, due to loading magnification, or biological, affecting cell metabolism, is unknown. Previous work (Merryman, 2002) showed that there was no significant effect upon monolayer IVD cells loaded at 15Hz, while lower frequencies (1 and 8Hz) altered collagen synthesis compared to control. To address this issue, we developed a mechanically active culture system capable of delivering a wide range of loading frequencies and amplitudes of hydrostatic pressure to cultures of disc cells. Nucleus pulposus cells of pig discs were isolated and suspended in alginate beads. Alginate cultures were divided into 6 groups; five groups were exposed to cyclic pressures of frequencies 1, 3, 5, 8, and 10Hz with the same amplitude of 1MPa, and group 6 was the control group (no loading). Cultures of different groups were loaded for 3 days (30 minutes daily) in a hydraulic chamber filled with culture media. The effect of loading frequency on collagen metabolism among different groups was compared by measuring incorporated [3H]-proline into collagen for medium and total extracts. The results indicated a poor synthesis rate and more degradation near the 5Hz frequency.

Abstract:
The article focuses on the «Intellectual Dark Web», an informal group of scholars, publicists, and activists who openly opposed the identity politics, political correctness, and the dominance of leftist ideas in American intellectual life. The author examines the reasons for the emergence of this group, names the main representatives and finds that the existence of «dark intellectuals» is the evidence of important problems in US public discourse. The term «Intellectual Dark Web» was coined by businessman Eric Weinstein to describe those who openly opposed restrictions on freedom of speech by the state or certain groups on the grounds of avoiding discrimination and hate speech. Extensive discussion of the phenomenon of «dark intellectuals» began after the publication of Barry Weiss’s article «Meet the renegades from the «Intellectual Dark Web» in The New York Times in 2018. The author writes of «dark intellectuals» as an informal group of «rebellious thinkers, academic apostates, and media personalities» who felt isolated from traditional channels of communication and therefore built their own alternative platforms to discuss awkward topics that were often taboo in the mainstream media. One of the most prominent members of this group, Canadian clinical psychologist Jordan Peterson, publicly opposed the C-16 Act in September 2016, which the Canadian government aimed to implement initiatives that would prevent discrimination against transgender people. Peterson called it a direct interference with the right to freedom of speech and the introduction of state censorship. Other members of the group had a similar experience that their views were not accepted in the scientific or media sphere. The existence of the «Intellectual Dark Web» indicates the problem of political polarization and the reduction of the ability to find a compromise in the American intellectual sphere and in American society as a whole.

Automated-Entry Patient-Generated Health Data for Chronic Conditions: The Evidence on Health Outcomes.

Abstract:
Background. Automated-entry consumer devices that collect and transmit patient-generated health data (PGHD) are being evaluated as potential tools to aid in the management of chronic diseases. The need exists to evaluate the evidence regarding consumer PGHD technologies, particularly for devices that have not gone through Food and Drug Administration evaluation. Purpose. To summarize the research related to automated-entry consumer health technologies that provide PGHD for the prevention or management of 11 chronic diseases. Methods. The project scope was determined through discussions with Key Informants. We searched MEDLINE and EMBASE (via EMBASE.com), In-Process MEDLINE and PubMed unique content (via PubMed.gov), and the Cochrane Database of Systematic Reviews for systematic reviews or controlled trials. We also searched ClinicalTrials.gov for ongoing studies. We assessed risk of bias and extracted data on health outcomes, surrogate outcomes, usability, sustainability, cost-effectiveness outcomes (quantifying the tradeoffs between health effects and cost), process outcomes, and other characteristics related to PGHD technologies. For isolated effects on health outcomes, we classified the results in one of four categories: (1) likely no effect, (2) unclear, (3) possible positive effect, or (4) likely positive effect. When we categorized the data as “unclear” based solely on health outcomes, we then examined and classified surrogate outcomes for that particular clinical condition. Findings. We identified 114 unique studies that met inclusion criteria. The largest number of studies addressed patients with hypertension (51 studies) and obesity (43 studies). Eighty-four trials used a single PGHD device, 23 used 2 PGHD devices, and the other 7 used 3 or more PGHD devices. Pedometers, blood pressure (BP) monitors, and scales were commonly used in the same studies. Overall, we found a “possible positive effect” of PGHD interventions on health outcomes for coronary artery disease, heart failure, and asthma. For obesity, we rated the health outcomes as unclear, and the surrogate outcomes (body mass index/weight) as likely no effect. For hypertension, we rated the health outcomes as unclear, and the surrogate outcomes (systolic BP/diastolic BP) as possible positive effect. For cardiac arrhythmias or conduction abnormalities we rated the health outcomes as unclear and the surrogate outcome (time to arrhythmia detection) as likely positive effect. The findings were “unclear” regarding PGHD interventions for diabetes prevention, sleep apnea, stroke, Parkinson’s disease, and chronic obstructive pulmonary disease. Most studies did not report harms related to PGHD interventions; the relatively few harms reported were minor and transient, with event rates usually comparable to harms in the control groups. Few studies reported cost-effectiveness analyses, and only for PGHD interventions for hypertension, coronary artery disease, and chronic obstructive pulmonary disease; the findings were variable across different chronic conditions and devices. Patient adherence to PGHD interventions was highly variable across studies, but patient acceptance/satisfaction and usability was generally fair to good. However, device engineers independently evaluated consumer wearable and handheld BP monitors and considered the user experience to be poor, while their assessment of smartphone-based electrocardiogram monitors found the user experience to be good. Student volunteers involved in device usability testing of the Weight Watchers Online app found it well-designed and relatively easy to use. Implications. Multiple randomized controlled trials (RCTs) have evaluated some PGHD technologies (e.g., pedometers, scales, BP monitors), particularly for obesity and hypertension, but health outcomes were generally underreported. We found evidence suggesting a possible positive effect of PGHD interventions on health outcomes for four chronic conditions. Lack of reporting of health outcomes and insufficient statistical power to assess these outcomes were the main reasons for “unclear” ratings. The majority of studies on PGHD technologies still focus on non-health-related outcomes. Future RCTs should focus on measurement of health outcomes. Furthermore, future RCTs should be designed to isolate the effect of the PGHD intervention from other components in a multicomponent intervention.

Abstract:
For meat and meat products, secondary processes are those that relate to the downstream of the primary chilling of carcasses. Secondary processes include maturation chilling, deboning, portioning, mincing and other operations such as thermal processing (cooking) that create fresh meat, meat preparations and ready-to-eat meat products. This review systematically identified and summarised information relating to antimicrobial resistance (AMR) during the manufacture of secondary processed meatand meat products (SPMMP). Systematic searching of eight literature databases was undertaken and the resultantpapers were appraised for relevance to AMR and SPMMP. Consideration was made that the appraisal scores, undertaken by different reviewers, were consistent. Appraisal reduced the 11,000 initially identified documents to 74, which indicated that literature relating to AMR and SPMMP was not plentiful. A wide range of laboratory methods and breakpoint values (i.e. the concentration of antimicrobial used to assess sensitivity, tolerance or resistance) were used for the isolation of AMR bacteria.The identified papers provided evidence that AMR bacteria could be routinely isolated from SPMMP. There was no evidence that either confirmed or refuted that genetic materials capable of increasing AMR in non-AMR bacteria were present unprotected (i.e. outside of a cell or a capsid) in SPMMP. Statistical analyses were not straightforward because different authors used different laboratory methodologies.However, analyses using antibiotic organised into broadly-related groups indicated that Enterobacteriaceaeresistant to third generation cephalosporins might be an area of upcoming concern in SPMMP. The effective treatment of patients infected with Enterobacteriaceaeresistant to cephalosporins are a known clinical issue. No AMR associations with geography were observed and most of the publications identified tended to be from Europe and the far east.AMR Listeria monocytogenes and lactic acid bacteria could be tolerant to cleaning and disinfection in secondary processing environments. The basis of the tolerance could be genetic (e.g. efflux pumps) or environmental (e.g. biofilm growth). Persistent, plant resident, AMR L. monocytogenes were shown by one study to be the source of final product contamination. 4 AMR genes can be present in bacterial cultures used for the manufacture of fermented SPMMP. Furthermore, there was broad evidence that AMR loci could be transferred during meat fermentation, with refrigeration temperatures curtailing transfer rates. Given the potential for AMR transfer, it may be prudent to advise food business operators (FBOs) to use fermentation starter cultures that are AMR-free or not contained within easily mobilisable genetic elements. Thermal processing was seen to be the only secondary processing stage that served as a critical control point for numbers of AMR bacteria. There were significant linkages between some AMR genes in Salmonella. Quaternary ammonium compound (QAC) resistance genes were associated with copper, tetracycline and sulphonamide resistance by virtue of co-location on the same plasmid. No evidence was found that either supported or refuted that there was any association between AMR genes and genes that encoded an altered stress response or enhanced the survival of AMR bacteria exposed to harmful environmental conditions.
