La phénoménologie psychiatrique contemporaine a pu lier altérations du soi minimal et troubles schizophréniques. En effet, des perturbations de cette composante du Self, qui serait le préalable de notre capacité à se ressentir comme agent de ses expériences et de les reconnaître comme siennes, expliqueraient les états particuliers de conscience rapportés par les patients schizophrènes. Si leur analyse doit être guidée par une lecture duale, laissant alterner hyper-réflexivité et troubles de l’intercorporéité, l’échelle descriptive offerte par l’EASE constitue un outil de prédilection au regard de l’investigation objective des altérations du Self Minimal. En favorisant la co-construction d’un langage pour décrire l’expérience du sujet, l’EASE permet de rendre compte des irrégularités du Self Minimal et revêt ainsi un enjeu diagnostique comme pronostique comme nous pourrons le voir. Deux modèles explicatifs dominent l’origine présumée de ces perturbations, attribuant respectivement ces modifications à des défaillances d’ordre métacognitif et à des processus précédant l’action – impliquant l’émission d’une copie d’efférence – troublés. L’altération du soi-minimal reste difficile à appréhender, mais nous souhaitons porter son analyse sous le prisme de deux œuvres de la culture populaire. Dans Cyberpunk 2077, le protagoniste expérimente l’insertion d’une personnalité dans sa psyché avec laquelle il devra cohabiter dans un but commun, présentant ainsi une altération du corps vécu. Dans Fight club, Tyler Durden expérimente la sensation parasitante d’être envahi par un corps étranger, dont il spatialise les faits au point de l’annihiler en se tirant une balle dans le crâne, et que l’on peut explorer sous le prisme du syndrome d’influence.

The interplay of exchange correlations and spin–orbit interaction (SOI) on the many-body spectrum of a copper phtalocyanine (CuPc) molecule and their signatures in transport are investigated. We first derive a minimal model Hamiltonian in a basis of frontier orbitals that is able to reproduce experimentally observed singlet–triplet splittings. In a second step SOI effects are included perturbatively. Major consequences of the SOI are the splitting of former degenerate levels and a magnetic anisotropy, which can be captured by an effective low-energy spin Hamiltonian. We show that scanning tunneling microscopy-based magnetoconductance measurements can yield clear signatures of both these SOI-induced effects.

With the emergence of mobile computing and communication, low power device design and implementation have got a significant role to play in VLSI circuit design. Conventional silicon (bulk CMOS) technology couldn‘t overcome the fundamental physical limitations belonging to sub-micro or nanometer region which leads to alternative device technology like Silicon-on-Insulator (SOI) technology. In a fully-depleted FDSOI structure the electrostatic coupling of channel with source/drain and substrate through the buried layer (BL) is reduced. This allows in turn to reduce the minimal channel length of transistors or to relax the requirements on Si film thickness. A generalized compact threshold voltage model for SOI-MOSFET is developed by solving 2-D Poisson‘s equation in the channel region and analytical expressions are also developed for the same. The performance of the device is evaluated after incorporating the short channel effects. It is observed that in SOI, presence of the oxide layer resists the short channel effects and reduces device anomalies such as substrate leakage by a great factor than bulk-MOS. The threshold voltage and current drive make SOI the ultimate candidate for low power application. Thus SOI-MOSFET technology could very well be the solution for further ultra scale integration of devices and improvised performance.

La cure psychanalytique témoigne que toute personne détient un « savoir » sur ce qui la constitue au plan psychique. En dehors de la cure analytique, en une ou quelques rencontres thérapeutiques en santé mentale, la personne qui consulte peut-elle accéder à un savoir « minimal » sur elle ? S’appuyer sur celui-ci pour orienter certains aspects de sa vie fait appel à une éthique de la responsabilité chez la personne qui consulte. Faire advenir ce savoir réclame de la part du clinicien une conception de l’humain qui prend en compte les dimensions subjectives de la personne.

This paper details the application of phosphorus monolayer doping of silicon on insulator substrates. There have been no previous publications dedicated to the topic of MLD on SOI, which allows for the impact of reduced substrate dimensions to be probed. The doping was done through functionalization of the substrates with chemically bound allyldiphenylphosphine dopant molecules. Following functionalization, the samples were capped and annealed to enable the diffusion of dopant atoms into the substrate and their activation. Electrical and material characterisation was carried out to determine the impact of MLD on surface quality and activation results produced by the process. MLD has proven to be highly applicable to SOI substrates producing doping levels in excess of 1 × 1019 cm−3 with minimal impact on surface quality. Hall effect data proved that reducing SOI dimensions from 66 to 13 nm lead to an increase in carrier concentration values due to the reduced volume available to the dopant for diffusion. Dopant trapping was found at both Si–SiO2 interfaces and will be problematic when attempting to reach doping levels achieved by rival techniques.

The growing demand for hybrid electric vehicles (HEVs) has increased the need for high-temperature electronics that can operate at the temperatures that exist under the hood of these vehicles. In many cases this requires the use of thermal management systems to allow for the use of components not designed to operate at the ambient temperatures found in the engine compartment of an HEV. These systems add weight and complexity, which can increase the overall cost and reduce the efficiency of the vehicle. The alternative is to develop circuits and systems capable of operating with reduced or no thermal management. To this end, the latest version of our high-temperature gate driver integrated circuit (IC) has been developed. Designed and implemented on a 0.8-micron bipolar-CMOS-DMOS (BCD) on silicon-on-insulator (SOI) process, this gate driver chip is intended to drive silicon carbide (SiC) and other wide-bandgap (WBG) power field-effect transistors (FETs) for DC-DC converters and traction drives in HEVs. To enable this, the gate driver IC, which includes on-chip voltage regulators and protection circuitry, has been designed to operate at and successfully tested up to 200°C ambient temperature. Successful operation of the circuit at this temperature with minimal or no heat sink, and without liquid cooling, will help to achieve higher power-to-volume as well as power-to-weight ratios for the power electronics modules in HEVs.

Computer modeling is a method for solving the problems of analysis or synthesis of a complex system based on the use of its computer model. Simulation, as a component of computer modeling, allows you to construct most of the possible states of the analyzed system. In this way it allows to correct the processes of assembling machines in a minimum time and with minimal costs, to foresee possible risks and to avoid unreasonable decisions regarding the organization of processes, to reduce material costs. Simulation gives the best results for modeling uncertain or probabilistic systems. Simulation, as a component of computer modeling, gives the best results for modeling systems with uncertainty or with a probabilistic nature. Mathematically calculating all possible variants of the system’s behavior is a laborious task, and using average values in the calculations gives inaccurate results. For assembly production systems, simulation modeling is used to select the optimal production organization parameters. The aim of this work is to build a computer simulation model that allows you to evaluate the impact of production factors (number of employees, operating parameters and type of assembly process) on the assembly process and substantiate the effectiveness of the model. The current assembly process of the machine was considered for modeling. The assembly process includes: two streams of verification, synchronization of request from these two streams, and a machine collection stream. The vacated line starts servicing the application that entered the system earlier than others. Such a discipline is called “earlier entered - earlier served” (FIFO - First In - First Out).s from flows, and a machine assembly flow. An optimization experiment was carried out after the construction and verification of the simulation model. The maximum value of profit was chosen as the objective function. Iterations were performed during an optimization experiment. The optimal number of employees was selected for two inspection flows and a machine assembly stream in the assembly shop. The first experimental result showed the effectiveness of the request flow synchronization method. The following optimization experiment showed the relationship between the number of workers in certain threads of the assembly process and profit. The results of using agent-based models for simulation can be used to optimize assembly processes.

Célèbres par leur lutte contre l'intolérance, les philosophes du XVIIIe siècle n'ont cependant pas été les apôtres d'une tolérance inconditionnelle, conçue comme excellente en soi. Toute la difficulté tient, en effet, à l'existence de l'intolérable, laquelle rend indispensable l'analyse de ce qu'on doit ou ne doit pas tolérer. Voltaire fait de la tolérance un devoir minimal, destiné à être remplacé par la fraternité, cependant que Rousseau, dans sa fine analyse des mystifications engendrées par la prétendue tolérance, risque lui-même de passer pour intolérant. Dans le domaine de la religion, l'idéal de tolérance tend finalement à être dépassé vers la fin du siècle.

Introduction : les schizophrénies sont les pathologies les plus représentées dans la population hospitalisée au long cours en psychiatrie. L'objectif est d'analyser la chronicisation à l'hôpital au sein de cette population. Méthode : à partir de quatre cas cliniques issus de notre pratique clinique et d'entretiens semi-structurés avec treize patients schizophrènes, nous avons effectué une analyse clinique et psychopathologique centrée sur la compréhension phénoménologique de l'expérience de la première hospitalisation. Ce matériel verbal a fait l'objet d'une analyse à la fois qualitative et quantitative. Résultats : plusieurs facteurs tels que l'atteinte du soi minimal, de l'expérience de la temporalité, du lien aux proches, mais aussi l'expérience de la violence, participent à l'installation d'une chronicité chez ces patients. En revanche, l'hôpital semble rarement être investi comme un chez-soi. Associée à la passivité induite par la dynamique institutionnelle, l'altération majeure du soi minimal entrave l'appropriation de l'expérience chez ces patients. Discussion : la chronicité dans l'expérience schizophrénique est une réalité clinique irréductible. Cela suppose de considérer le temps existentiel et d'interroger sans cesse le cadre de soins. Le sujet étant limité dans son processus de territorialisation au moment même de l'évènement de son hospitalisation, nous relevons dans son discours un défaut de transpassibilité de celui-ci, signant sa difficulté d'appropriation et conduisant à l'incompréhension au sens évènemential de l'hospitalisation et de son issue. Conclusion : dans les schizophrénies les enjeux existentiels sont inhérents à l'expérience de l'hospitalisation. L'institution doit elle-même être soignée afin de préserver sa capacité de pensée et maintenir une dynamique ajustée à la prise en charge des patients souffrant de schizophrénieIntroduction : Among the long-term psychiatric hospitalized population, schizophrenia is the most frequent diagnosis. The objective is to analyze chronicity within this population of patients. Method : based on four clinical cases from our clinical practice and semi-structured interviews with thirteen schizophrenic patients, we performed a clinical and psychopathological analysis focused on the phenomenological understanding of the experience of first hospitalization. This verbal material underwent double analysis, both qualitative and quantitative rooted in statistics and n'vivo. Results : Several factors as the alteration of minimal self, the experience of temporality and the bonds with significant others participate, as well as the experience of violence, in establishing chronicity for these patients. On the other hand, the hospital seems to be invested as a home infrequently. Associated with the passivity induced by the institutional dynamics, the major alteration of minimal self hinders the appropriation of experience in these patients. Discussion : chronicity in the schizophrenic experience is an irreducible clinical reality. It involves considering existential time and constant screening of the setting. As the patient is limited in his territorialization process at the very moment of the event of his hospitalization, we identify in his speech a lack of transpassability that indicates a difficulty in appropriation leading to incomprehension of hospitalization and its outcome. Conclusion : in schizophrenia, the existential stakes are inherent to the experience of hospitalization. The institution itself must be questioned in order to preserve its capacity of thought and holding in order to maintain a dynamic specifically adjusted to the care of schizophrenic patients

Resumo: Este trabalho teve como objetivos: quantificar a taxa respiratória, a produção de etileno e a atividade enzimática de toletes de palmito Pupunha; determinar a temperatura adequada para a conservação da qualidade e avaliar sistemas de embalagem com atmosfera modificada. O primeiro experimento teve por objetivo quantificar a taxa respiratória e a produção de etileno em toletes de palmito Pupunha armazenados nas temperaturas de 1,5±1oC, 5±1oC, 10±1oC e 25±1oC e 85±5% de umidade relativa. As análises da concentração de oxigênio (O2), dióxido de carbono (CO2) e etileno (C2H4) foram feitas por cromatografia gasosa.Também foi determinada a perda de massa dos toletes armazenados nas quatro temperaturas. A atividade respiratória, a biossíntese de C2H4 e a perda de massa de toletes de palmito Pupunha são influenciadas pelas temperaturas de armazenamento. No segundo experimento foi feita a caracterização físico-química de toletes de palmito Pupunha do verão e do inverno. Os toletes foram armazenados a 10,0±1oC, 5,0±1oC e 1,5±1oC com umidade relativa de 85±5%. O rendimento de toletes por haste cortada foi 30% menor no inverno e seus valores de firmeza foram maiores que os do verão. A perda de massa foi maior nos toletes colhidos no verão. A condição climática não exerceu efeito sobre o pH e acidez dos toletes. No terceiro experimento os toletes foram embalados em PELBD e PVC esticáveis e em filme poliolefínico (CT301) e armazenados a 5oC. Verificou-se que a menor concentração de O2 no interior das embalagens com PVC não reduziu a concentração de C2H4 e também não afetou a atividade da peroxidase nos toletes de palmito Pupunha. A maior concentração de CO2 no interior das embalagens PVC não exerceu efeito inibidor sobre a ação do C2H4 nos toletes. Os toletes de palmito Pupunha embalados em PVC e armazenados a 5,0oC apresentaram-se microbiologicamente seguros para o consumo até o 15o dia pós-colheita, enquanto os acondicionados em PELBD e CT301 até o 6º dia. A baixa concentração de O2 no interior das embalagens de PVC reduziu o crescimento de microrganismos deteriorantes
Abstract: This study aimed to quantify the respiratory rate, ethylene production and enzymatic activity of Pupunha hearts of palm and to determine the temperature for preserving the product, and to evaluate modified atmosphere packaging systems for product conservation. The first test aimed to quantify the respiratory rate and ethylene production of Pupunha hearts of palm stored at 25.0oC, 10.0oC, 5.0oC and 1.5oC and 85 ± 5% RH. The analysis of the concentration of oxygen (O2), carbon dioxide (CO2) and ethylene (C2H4) were made by gas chromatography. The weight loss was also determined. The storage temperatures effected the respiratory rate and C2H4 concentration of Pupunha hearts of palm. In the second experiment, Pupunha hearts of palm were harvested during the summer and winter. The hearts of palm were stored at 10.0 ± 1oC, 5.0 ± 1oC and 1.5 ± 1oC at relative humidity of 85 ± 5%. The yield of the stems cut in the winter was 30% lower and the hearts of palms were tougher. Weight loss was higher for hearts of palm harvested in the summer. Tritatable acidity and pH were not affected by the harvesting season. In the third assay, Pupunha hearts of palm were packed with stretchable PVC and LDPE films and with a polyolefinic film (CT301) and stored at 5oC. The low O2 concentration in the PVC packagings did not affect C2H4 concentration and the peroxidase activity. Hearts of palm packed in PVC and stored at 5.0oC were microbiologically safe up to the 15th postharvest day, and those packed in LDPE and CT301 up to the 6th day. The low O2 concentration in the PVC packaging reduced microbial deterioration

Mestrado em FinançasEsta dissertação tem como objectivo analisar vários modelos de gestão de carteiras, tendo em consideração gestão activa e passiva e o seu impacto na escolha eficiente de uma carteira ótima composta por activos do índice bolsista Suiço - SMI. A minha escolha recaíu sobre a Suiça por várias razões. Em primeiro lugar, seria interessante perceber o comportamento de um mercado europeu que não utilizasse a moeda única. Outra das razões foi por este mercado incorpora algumas grandes empresas multinacionais, tais como a Nestlé e a Swatch. A análise histórica das carteiras teve em conta o modelo Markowitz (média-variância), modelo Mínima-Variância e o modelo Naïve (pesos iguais). O horizonte temporal utilizado neste estudo foi de 10 anos, considerando o período de Janeiro de 2004 a Dezembro de 2013. Os dados foram retirados da base de dados académica Datastream. Para calcular o peso a investir em cada ativo, foram utilizados os sistemas de ?janelas de dados? a 1 e 2 anos. Por fim, será possível observer se, para 12 meses, existem ou não diferenças significativas entre os modelos de gestão de carteiras estudados nesta dissertação. Será também possível analisar se, para rendibilidades e rácios de Sharpe mais elevados, a carteira ótima é a melhor opção.
This study aims to analyze various models of portfolio management, underlying the active and passive management and its impact on the efficient choice of an optimal portfolio composed by assets from Swiss shares index - SMI. I chose Swiss market for a couple of reasons. First of all, it would be interesting to analyze the behavior of an European market that doesn't belong to Euro. Another reason was the fact of this market have some big international companies such as Nestlé and Swatch. Historical portfolio analysis took into account the Markowitz model (mean-variance), the Minimum Variance model and the Naïve model (equal weights). The time horizon used in this dissertation was 10 years and considers the period between January, 2004 and December, 2013. The data were obtained from academic database Datastream. To compute the weight to invest in each asset, ?data window system' for 1 and 2 years will be used. To conclude, we will be able to see if, for 12 months, there are or not significant differences between the types of portfolio management treated throughout the dissertation. Further on, we may consider if for higher returns and Sharpe Ratio, the optimal portfolio is the best option.

Resumo: No mundo atual é crescente a demanda dos consumidores por produtos frescos, devido a sua qualidade nutricional, além de oferecer benefícios para a saúde como, por exemplo, na prevenção de algumas doenças. Frente a esta demanda, o presente trabalho estudou o uso de coberturas comestíveis de fécula de mandioca na manutenção da qualidade dos frutos de morango (Fragaria ananassa Duch.). Os frutos de morango receberam tratamentos combinando o processamento mínimo com a utilização de cobertura comestível de fécula de mandioca, cuja finalidade foi prolongar a vida útil destes em temperaturas de refrigeração. Os frutos após o processamento foram mergulhados por 10 minutos em suspensão de 3% (p/v) de fécula de mandioca e submetidos à secagem naturalmente à temperatura ambiente e armazenados em temperaturas de 10 ?C e 15 ?C. Na primeira etapa, o objetivo foi avaliar as características da cobertura aplicada nos morangos (propriedades mecânicas: forças de ruptura e penetração, cor dos morangos, taxa de respiração e resistência ao vapor de agua) depois de 24 horas do tratamento. A aplicação da cobertura nos morangos não alterou significativamente as propriedades mecânicas (forças de ruptura e penetração), cor dos morangos, taxa de respiração e resistência ao vapor de água em comparação aos morangos sem coberturas. Na segunda etapa foi realizado o estudo da vida útil dos morangos com e sem cobertura, armazenados a temperaturas de 10 ?C e 15 ?C. Na perda de peso verificou-se diferença significativa ao longo do tempo de armazenamento diferença significativa, e no tempo fixo não se observou diferenças significativas entre os tratamentos, a taxa de respiração mostrou um incremento significativo em todos os tratamentos ao longo no tempo de armazenamento e para tempo fixo não presentaram diferenças significativo entre os tratamentos exceto no dia 1 se observou que o tratamento 15 ?C com cobertura diminui significativamente com respeito a 15 ?C sem cobertura. O teor de antocianinas apresentou uma diminuição significativa ao longo do tempo de armazenamento para os tratamentos 10 ?C sem cobertura e 15 C sem e com cobertura em ambas temperaturas são não significativo nos dia 5 e 8. As amostras 10 ?C com e sem cobertura e 15 ?C com e sem cobertura foram avaliadas sensorialmente os morangos com cobertura apresentaram notas acima do limite de aceitação (4,5), o fator que determinou o tempo de vida útil foi a contaminação microbiológica observada nas amostras. As amostras armazenadas a 10 ?C com e sem cobertura apresentaram 8 dias de vida útil e as amostras armazenadas 15 ?C com e sem cobertura apresentaram 5 dias de vida útil
Abstract: Nowadays there is a growing consumer demand for fresh products, due to their nutritional quality and the health benefits they provide, for example, in the prevention of some diseases. Faced with this demand, the present work analyzed the use of edible cassava starch coating for preserving the quality of strawberry fruits (Fragaria ananassa Duch.). Strawberries underwent treatment combining minimal processing with the use of edible cassava starch coating, aiming to extend the lifetime of these fruits at refrigerated temperatures. To this aim, after the processing stage, the fruits were immersed for 10 minutes in a 3% (w/v) cassava starch suspension; then they were naturally dried at room temperature and stored at temperatures of 10?C and 15?C. During the first stage, the objective was to evaluate the characteristics of the starch-based coating applied to strawberries ¿ that is, mechanical properties (compression and penetration strengths) strawberry color, respiration rate and water vapor resistance ¿ after a 24-hour treatment. The application of the coating on the strawberries did not significantly modify the mechanical properties (compression and penetration strengths), strawberry color, respiration rate and resistance to water vapor, when compared to uncoated strawberries. During the second stage we studied the lifetime of coated and uncoated strawberries stored at temperatures of 10?C and 15?C. In the weight loss treatments, we were able to verify significant differences during the storage time, and in the fixed time no significant differences were observed, the respiration rate showed significant increase in all treatments during storage time, and in the fixed time, no significant differences among treatments were seen, except for day 1, when it was observed that the coated fruits under treatment at 15 ?C showed a significant decrease with regard to the uncoated fruits treated at 15?C. The anthocyanin content showed significant decrease during storage time for uncoated fruits at 10?C and for coated and uncoated fruits at 15?C; at both temperatures there were no significant results on days 5th and 8th. Sensory analysis was performed on samples at coated and uncoated stored at 10?C and 15?C . Coated strawberries showed numbers above the acceptance limit (4.5). The factor that determined the lifetime was the microbiological contamination observed in the samples. Coated and uncoated samples stored at 10?C had an 8-day lifetime and the coated and uncoated samples stored at 15?C had a 5-day lifetime

Previous issue date: 2011-07-04The vegetables are highly perishable and their post-harvest storage is relatively short. The increased lifetime in a day or more is very important for the marketing of vegetables. An alternative to reducing losses and better use the harvest is the minimal processing, it combines convenience and practicality to be a product ready for consumption. However, some problems hindering the extension of shelf life of products such as high respiratory rate and proliferation of microorganisms. The use of growth regulators like 1-methylcyclopropene (1-MCP), an antagonist of ethylene action, and the use of plastic films have been widely studied in association with the use of low temperatures. For this study three experiments were made in order to verify the efficiency of use of 1-MCP and promalina in reducing the senescence of broccoli inflorescences, evaluate the performance of minimally processed cabbage and packed in four kinds of packaging and efficiency of 1-MCP and storage in three packaging minimally processed lettuce. Inflorescences of broccoli cultivar Avenger were sanitized, treated with 2.5 ppm 1-MCP, 50 ppm promalina, combination of 50 ppm and 2.5 ppm promalina of 1-MCP and stored in polyethylene film bags of low density (LDPE) for storage at 5 ± 2 ° C cold room. Heads of cabbage cultivar Red Dynasty were minimally processed, sanitized and packed in polyethylene terephthalate (PET) with lid, polystyrene trays (EPS) of flexible film coated with polyvinyl chloride (PVC), LDPE film and polypropylene film (PP) punched, and stored at 5 ± 2 ° C cold room. Heads of lettuce cultivar Vanda were minimally processed, sanitized, treated with 1-MCP and stored in PET bottles with lids, trays EPS coated flexible film of PVC and LDPE film, and stored at 4 ± 2 º C in cold . Treatment with MCP-1 contributed to the longevity of broccoli inflorescences up to twenty-seven days at a temperature of 5 ± 2 º C. Treatment with the combination of promalina with 1-MCP were not favorable. Regardless of the type of packaging minimally processed cabbage should not exceed four days, because I had blackened appearance due to oxidation. The PET was efficient associated with 1-MCP providing better quality for up to twelve days.
As hortaliças possuem alta perecibilidade pós-colheita e seu armazenamento é relativamente curto. O aumento da vida útil em um ou mais dias é muito importante para a comercialização das hortaliças. Uma alternativa para a redução de perdas e melhor utilização da colheita é o processamento mínimo, pois alia conveniência e praticidade por ser um produto pronto para o consumo. Entretanto, alguns problemas dificultam a extensão da vida de prateleira desses produtos, tais como alta taxa respiratória e proliferação de microrganismos. O uso de fitorreguladores como o 1-metilciclopropeno (1-MCP), um antagonista de ação do etileno, e a utilização de filmes plásticos têm sido amplamente estudados em associação com o uso de baixas temperaturas. Para a realização deste estudo foram feitos três experimentos com o objetivo de verificar a eficiência do uso do 1-MCP e da promalina na redução da senescência de inflorescências de brócolis, avaliar o comportamento do repolho roxo minimamente processado e embalado em quatro tipos de embalagem e a eficiência do 1-MCP e de três embalagens no armazenamento de alface minimamente processada. Inflorescências de brócolis da cultivar Avenger foram sanitizadas, tratadas com 2,5 ppm de 1-MCP, 50 ppm de promalina, combinação de 50 ppm de promalina e 2,5 ppm de 1-MCP e acondicionados em sacos de filme de polietileno de baixa densidade (PEBD) para armazenamento a 5±2ºC em câmara fria. Cabeças de repolho roxo da cultivar Red Dynasty foram minimamente processadas, sanitizadas e acondicionadas em embalagens de tereftalato de polietileno (PET) com tampa, bandejas de poliestireno expandido (EPS) revestidas com filme flexível de policloreto de vinila (PVC), filme de PEBD e filme de polipropileno (PP) perfurado, e armazenadas a 5±2ºC em câmara fria. Cabeças de alface crespa da cultivar Vanda foram minimamente processadas, sanitizadas, tratadas com 1-MCP e acondicionadas em embalagens de PET com tampa, bandejas de EPS revestidas com filme flexível de PVC e filme de PEBD, e armazenadas a 4±2ºC em câmara fria. O tratamento com 1-MCP contribuiu na longevidade das inflorescências do brócolis por até vinte e sete dias à temperatura de 5±2ºC. Os tratamentos com promalina e a combinação deste com o 1-MCP não se mostraram favoráveis. Independente do tipo de embalagem o repolho roxo minimamente processado não deve ultrapassar quatro dias, pois já apresentava aparência escurecida devido à oxidação. A embalagem PET mostrou-se eficiente associada ao 1-MCP proporcionando melhor qualidade por até doze dias.

This study aimed to evaluate the use of modified atmosphere (MA) in the conservation of sweet cassava variety 'Pernambuana' minimally processed in plastic containers. In the first stage determined the chemical composition (macro and micronutrients), heavy metals, the cooking time (DTC), quality of cooking and cyanogenic compounds. Minimal processing was the subdivision into two areas, dirty areas: reception of raw materials, selection, classification and pre-wash. In the second step, the clean area: processing (peeling and cutting), rinse, sanitizing, spinning, packing, storage. We analyzed the gas concentration (O2 and CO2) inside the package by 70 pm. The experiment was conducted at temperature 10 °C and stored in polystyrene containers terephthalate (PET) without PVC (CONT), PET with PVC (AMCF), sealed polyethylene bags without vacuum (AMSV) and vacuum (AMCV) at 5 ± 0.2 º C, RH 43% for 20 days. Were performed physical and chemical analysis. The increase in browning (IE), staining of cuttings (L *, C *, H *). and enzyme activity were performed every four days until the 16th day. The microbiological analysis of fecal and total coliforms were performed on the day of processing, with eight and sixteen days. The variety 'Pernambucana‟ has got cooking time of 20 minutes, quality mass formed after cooking and low levels of cyanogenic compounds. It was observed that the pH, ascorbic acid, varied significantly during storage. There were statistical differences (P ≤ 0.05) for the values of reducing sugars, total soluble sugars during periods of storage. Packaging (AMSV and AMCV) had the highest values of L *, the lowest increment of darkening, a smaller reduction of ascorbic acid, however, had the highest pH values. The enzymes showed no statistical differences (P ≤ 0.05) for the activity of peroxidase and polyphenol in storage periods and between treatments. Considering the physico-chemical and microbial life of cassava was 12 days for treatments AMSVand AMCV and eight days for the treatment AMCF. According to the microbiological analysis of cassava breeding minimally processed showed an absence of coliform bacteria at 45 °C, however, treatment with AMCF, and AMSV AMCV showed total coliform counts considered high.

O sistema de cultivo mínimo é caracterizado por um conjunto de operações mínimas de preparo de solo em que a maior parte dos resíduos florestais é mantida sobre o solo, a fim de garantir as demandas de produção e a sustentabilidade produtiva do sistema. Diante disto, os objetivos deste estudo foram: i) Avaliar a influência da remoção total ou parcial dos resíduos florestais e da fertilização mineral na fertilidade do solo e na produtividade de madeira; ii) Quantificar a biomassa e o estoque de nutrientes na parte aérea, em uma rotação de cultivo, sob manejo de resíduos florestais e omissões de nutrientes na fertilização mineral; iii) Quantificar a influência do manejo de resíduos florestais e da fertilização mineral na deposição, acúmulo, decomposição e qualidade nutricional da serapilheira; iv) Quantificar a exportação de nutrientes via colheita de madeira e outros componentes florestais; v) Avaliar o potencial de produtividade de madeira, com base no balanço nutricional, sob diferentes cenários de manejo florestal. Foi instalado um experimento com diferentes manejos de resíduos florestais e fertilização. Os tratamentos foram divididos em dois grupos em que o primeiro consistiu em remoção total ou parcial dos resíduos florestais: copa (folhas e galhos), casca e serapilheira. O segundo grupo de tratamentos consistiu na omissão de nutrientes na fertilização mineral: N, P, K ou calagem. Durante a rotação de oito anos foram monitoradas a fertilidade do solo, ciclagem biogeoquímica de nutrientes, crescimento e estado nutricional das árvores. Os diferentes manejos dos resíduos florestais e fertilização mineral apresentaram pouca influência na fertilidade do solo, pois, os níveis de nutrientes no solo estavam adequados, devido à aplicação de fertilizantes minerais no momento da instalação do experimento. A remoção total ou parcial dos resíduos florestais não influenciou a produtividade de madeira. Contudo, no tratamento em que o K foi omitido na fertilização, houve redução de 50% na produtividade de madeira. A omissão de P na fertilização não afetou a produtividade de madeira na rotação de cultivo avaliada, porém este foi o nutriente mais limitante quanto ao número potencial de futuras rotações. A remoção total ou parcial dos resíduos florestais não influenciou na ciclagem biogeoquímica de nutrientes, porém omissão de K via fertilização reduziu em 60% a deposição anual deste nutriente o que afetou sua a ciclagem biogeoquímica. Os resultados deste estudo mostram que embora os resíduos florestais exerçam funções fundamentais na qualidade química do solo e na nutrição mineral das árvores, a inadequada fertilização do solo pode diminuir expressivamente o potencial produtivo do sítio florestal.The minimal tillage system is characterized by practices of reduced soil management which retains most part of forest residues in the production site, aiming to supply the forest demand and the sustainability of the production system. The aims of this study are: i) Access the effect on soil fertility and site production of total and partial removal of harvest residues and mineral fertilization. ii) Quantify the biomass and nutrient rates in trees along one eucalypt rotation, under different residues management and mineral fertilization. iii) Quantify the effects of residues management and mineral fertilization on deposition, accumulation, decomposition and nutritional qualities of litter. iv) Quantify the nutrient exportation due to the harvest, considering steam and other parts. v) Access productivity potential according to the nutritional balance under different forest management cases. For this study an experimental site with different residues management and mineral fertilization was established. The treatments were separated in two groups. The first one included the treatments with total or partial removal of forest residues: canopy (leaves and stems), bark and litter. The second group of treatment included the omission of nutrients in mineral fertilizer: N, P, K or lime. During eight years rotation were monitored soil fertility, biogeochemical cycling of nutrients, growth and tree nutritional status. The different residues management and mineral fertilizations has showed minor effects on soil fertility once the nutrient rates on soil were suitable due to the mineral fertilization applied for site preparation. However, when the fertilization was carried out without K, reduction of 50% in growth was observed. The omission of P in fertilization did not affect the wood productivity during the forest rotation, but P was the most limiting nutrient for the potential number of future rotations. The biochemical nutrient cycling was not affected by total or partial removal of forestry residues. Annual deposition of K was 60% reduced when the nutrient was not applied by fertilization, which affected the nutrient cycling. The results of this study demonstrated that despite the benefits of forest residues retention on chemical proprieties of soils, the inadequate fertilization reduces expressively the productive potential of the site.

AbstractThis paper has identified a minimal configuration of a DNN architecture and hyperparameter settings to effectively estimate SOC of EV battery cells. The results from the experimental work has shown that a minimal configuration of hidden layers and neurons can reduce the computational cost and resources required without compromising the performance. This is further supported by the number of epochs taken to train the best DNN SOC estimations model. Hence, demonstrating that, the risk of overfitting estimation models to training datasets, can also be subsided. This is further supported by the generalisation capability of the best model demonstrated through the decrease in error metrics values from test phase to those in validation phase.

AbstractInspired by sum-of-infeasibilities methods in convex optimization, we propose a novel procedure for analyzing verification queries on neural networks with piecewise-linear activation functions. Given a convex relaxation which over-approximates the non-convex activation functions, we encode the violations of activation functions as a cost function and optimize it with respect to the convex relaxation. The cost function, referred to as the Sum-of-Infeasibilities (SoI), is designed so that its minimum is zero and achieved only if all the activation functions are satisfied. We propose a stochastic procedure, , to efficiently minimize the SoI. An extension to a canonical case-analysis-based complete search procedure can be achieved by replacing the convex procedure executed at each search state with . Extending the complete search with achieves multiple simultaneous goals: 1) it guides the search towards a counter-example; 2) it enables more informed branching decisions; and 3) it creates additional opportunities for bound derivation. An extensive evaluation across different benchmarks and solvers demonstrates the benefit of the proposed techniques. In particular, we demonstrate that SoI significantly improves the performance of an existing complete search procedure. Moreover, the SoI-based implementation outperforms other state-of-the-art complete verifiers. We also show that our technique can efficiently improve upon the perturbation bound derived by a recent adversarial attack algorithm.

Abstract Climate change and soil fertility decline are threatening food security in southern Africa and efforts have been made to adapt current cropping systems to the needs of smallholder farmers. Conservation Agriculture (CA) based on minimum soil disturbance, crop residue retention and crop diversification has been proposed as a strategy to address the challenges smallholder farmers face. Here we analyse the potential contributions of CA towards adaptation to the effects of climate change by summarizing data on infiltration, soil moisture dynamics and crop productivity under heat and drought stress. The data were taken in the main from CIMMYT's on-farm and on-station trial network. Data show that CA systems maintain 0.7-7.9 times higher water infiltration than the conventional tilled system depending on soil type, which increases soil moisture during the cropping season by 11%-31% between CA treatments and the conventional control treatment. This leads to greater adaptive capacity of CA systems during in-season dry spells and under heat stress. A supporting regional maize productivity assessment, analysing the results of numerous on-farm and on-station experiments, showed that CA systems will outperform conventional tillage practices (CP), especially on light-textured soils, under heat and drought stress. With higher rainfall and low heat stress, this relation was more positive towards CP and on clay soil there was no benefit of practising CA when rainfall was high. The long dry season and limited biomass production of CA systems in southern Africa require complementary good agricultural practices to increase other soil quality parameters (e.g. increased soil carbon) to maintain higher productivity and sustainability over time. This can be addressed by combinations of improved stress-tolerant seed, targeted fertilization, inclusion of tree-based components or green manure cover crops in the farming system, scale-appropriate mechanization and improved weed control strategies.

MEMS diaphragms utilizing an embedded cantilever array to sense pressure were investigated in an effort to detect blast-induced loads that potentially cause mild traumatic brain injury (mTBI). Overhanging cantilever beams of varying length sequentially contacted convexly deformed diaphragms during pressure loading to enable binned binary threshold pressure sensing. Diaphragms and overhanging cantilever beam arrays photolithographically defined using double-layer SOI-DRIE processes were designed to minimize footprint and maximize sensing resolution while avoiding diaphragm fracture. Analytic models based on classical plate theory were correlated with a FEA model to guide design decisions by predicting deflection behavior of circular diaphragms under uniformly distributed pressure loads. Fabricated sensors experimentally tested under static conditions revealed good agreement with modeling, and indicated such a sensor may be well-suited for integration into a future wearable device capable of sensing potentially mTBI-causing blasts using minimal power.

This report presents detailed histograms of data from the Regulated Substances Library (RSL) developed by the Illinois Department of Transportation (IDOT). RSL data are provided for state and IDOT region, IDOT district, and county spatial subsets to examine the spatial variability and its relationship to thresholds defining natural background concentrations. The RSL is comprised of surficial soil chemistry data obtained from rights-of-way (ROW) subsurface soil sampling conducted for routine preliminary site investigations. A selection of 22 inorganic soil analytes are examined in this report: Al, Sb, As, Ba, Be, Cd, Ca, Cr, Co, Cu, Fe, Pb, Mg, Mn, Hg, Ni, K, Se, Na, Tl, V, and Zn. RSL database summary statistics, mean, median, minimum, maximum, 5th percentile, and 95th percentile, are determined for Illinois counties and for recognized environmental concern, non-recognized environmental concern, and de minimis site contamination classifications.

This report presents a statistical analysis of the Regulated Substances Library (RSL) developed by the Illinois Department of Transportation. The RSL is comprised of surficial soil chemistry data obtained from rights-of-way subsurface soil sampling conducted for routine preliminary site investigations. The 3.7-million-record RSL database is compared with four independent studies of inorganic soil constituents of naturally occurring soils in Illinois. A selection of 22 inorganic soil analytes are examined in this study: Al, Sb, As, Ba, Be, Cd, Ca, Cr, Co, Cu, Fe, Pb, Mg, Mn, Hg, Ni, K, Se, Na, Tl, V, and Zn. RSL database summary statistics, mean, median, minimum, maximum, 5th percentile, and 95th percentile, are determined for Illinois counties and for recognized environmental concern, non-recognized environmental concern, and de minimis site contamination classifications. The RSL database at a 95% confidence level is compared with current and proposed thresholds for defining naturally occurring soil concentrations for the selected analytes. The revised thresholds proposed by Cahill in 2017 are predominantly larger than the current standards found in the Tiered Approach to Corrective Action Objectives rules and are in better agreement with observed distributions of soil concentrations for both naturally occurring and RSL soils. A notable exception is antimony (Sb), for which Cahill proposed a reduced threshold similar in magnitude to the median for many Illinois Department of Transportation districts.

The Manhattan Engineer District previously used the 191-acre Niagara Falls Storage Site (NFSS) in Niagara County, New York, to store radioactive residues and wastes from uranium (U) ore processing. At present, management practices will determine whether enhanced evapotranspiration rates produced by hybridized shrub willow cuttings planted in 2016 will affect groundwater hydrology. Two shrub willow varieties were planted in an approximately one-half acre area to examine growth performance along a U impacted sanitary sewer line. Additionally, control plots will compare the effectiveness of shrub willows to unplanted areas. Observations of the planted area after 18 months showed success of shrub willow growth with increasing biomass. Chemical analysis from tree tissue samples of the field study showed no significant uptake of U or thorium (Th) to date. A greenhouse study conducted in parallel to the field study tested the willows under controlled greenhouse conditions and evaluated their ability to grow and accumulate contaminants under controlled conditions. Results from the greenhouse study demonstrated that U accumulation was minimal. Thus, this study demonstrates that the shrub willows are not accumulators of U or Th, an advantageous characteristic that implies stabilized contaminants in the soil and no translocation of U into the aboveground biomass.

Soil water wettability or water repellency is a phenomenon that can affect infiltration and, ultimately, runoff. Thus, there is a need to develop a model that can quantitatively capture the influence of water repellency on infiltration in a physically meaningful way and within the framework of existing infiltration theory. The analytical model developed in this study relates soil sorptivity (an infiltration parameter) with contact angle (a direct measure of water repellency) for variably saturated media. The model was validated with laboratory experiments using a silica sand of known properties treated to produce controlled degrees of water repellency. The measured contact angle and sorptivity values closely matched the model‐predicted values. Further, the relationship between the frequently used water drop penetration time test (used to assess water repellency) and sorptivity was illustrated. Finally, the direct impact of water repellency on saturated hydraulic conductivity was investigated due to its role in infiltration equations and to shed light on inconsistent field observations. It was found that water repellency had minimal effect on the saturated hydraulic conductivity of structureless sand. A quantitative model for infiltration incorporating the effect of water repellency is particularly important for post‐fire hydrologic modeling of burned areas exhibiting water repellent soils.

Free trade areas (and customs unions) were established in a multilateral level since in Article XXIV of the GATT, and that is the legal minimum from which preferential trade agreements are now built. Some say CPTPP is part of a new generation of Free Trade Agreements because it goes deeper in the integration process. The CPTPP Agreement is a 584-page treaty, a very extensive legal instrument with 30 chapters, so when we talk about legal trends it refers to all 30 chapters at first. But it’s not the idea to explain every chapter in this text, not even just the dispute mechanisms, but the legal highlights that make the CPTPP an example of the new structure in international trade law. The CPTPP’s new chapters constitute the actual trade agenda and establish a minimum level of protection on topics not specially linked to trade, but which are now essential to talk about a new configuration of trade agreements, such as investments, intellectual property, e-commerce, among others

In this project we studied optimal use and adoption of sophisticated irrigation technologies. The stated objectives in the original proposal were to develop a conceptual framework for analyzing intra-season timing of water application rates with implications for crop and irrigation technology selection. We proposed to base the analysis on an intra-seasonal, dynamic, agro-economic model of plants' water demand, paying special attention to contamination of groundwater and soil in intensively cultivated areas that increasingly rely on water of lesser quality. The framework developed in the project integrates (i) a bio-physical model of water flow in the vadose zone and water uptake by plants and yield response with (ii) a dynamic management model to determine the optimal intra-season irrigation policy. It consists of a dynamic optimization model to determine irrigation rates at each point of time during the growing season and aggregation relating harvested yield with accumulated water input. The detailed dynamic approach provides a description of yield production processes at the plant’s level, and serves to determine intra-season irrigation decisions. Data derived from extensive field experiments were used to calibrate the model's parameters. We use the framework to establish the substitution between irrigation technology (capital) and water inputs; this is an important property of irrigation water productivity that has been overlooked in the literature. Another important feature investigated is the possibility to substitute fresh and saline water with a minimal productivity loss. The effects of soil properties and crop characteristics on optimal technology adoption have also been studied. We find that sandy soil, with low water holding capacity, is more conducive to adoption of sophisticated drip irrigation, as compared to heavier soils in which drainage losses are significantly smaller.

Review question / Objective: 1.- To systematize the available scientific evidence on rehabilitation models and rehabilitation registries systems, which allow for the assessment of people's functioning; 2.- To describe rehabilitation data registries systems used internationally and the "minimum data set" that relate to the functioning of persons. Eligibility criteria: - Population: Studies that have enrolled adult or paediatric patients, with any condition or pathology that could potentially result in low functioning or disability, related to impairments, activity limitation or restriction in participation, according to the International Classification of Functioning, Disability and Health (ICF) framework will be included. - Concept: Studies that submitted data from a rehabilitation registry, bank, or database containing a minimum data set will be included. These registries may include clinical and administrative information that can be used to improve the quality of care, monitor or answer research questions. - Context: Studies that have been conducted in a context of rehabilitation programs and assessment of function or disability, at any level of care, and that have directly or indirectly addressed aspects or variables that can account for functioning, capacity, or participation according to the ICF framework will be included. The inclusion of studies will not be limited by their methodological design, since they will be used to identify rehabilitation registries or databases, so primary studies (cohort studies, case-control studies, among others) and secondary studies (systematic reviews, exploratory reviews, among others) will be considered.

Distributed Acoustic Sensing (DAS) is a fiber optic sensing system that is used for vibration monitoring. At a minimum, DAS is composed of a fiber optic cable and an optic analyzer called an interrogator. The oil and gas industry has used DAS for over a decade to monitor infrastructure such as pipelines for leaks, and in recent years changes in DAS performance over time have been observed for DAS arrays that are buried in the ground. This dissertation investigates the effect that soil type, soil temperature, soil moisture, time in-situ, and vehicle loading have on DAS performance for fiber optic cables buried in soil. This was accomplished through a field testing program involving two newly installed DAS arrays. For the first installation, a new portion of DAS array was added to an existing DAS array installed a decade prior. The new portion of the DAS array was installed in four different soil types: native fill, sand, gravel, and an excavatable flowable fill. Soil moisture and temperature sensors were buried adjacent to the fiber optic cable to monitor seasonal environmental changes over time. Periodic impact testing was performed at set locations along the DAS array for over one year. A second, temporary DAS array was installed to test the effect of vehicle loading on DAS performance. Signal to Noise Ratio (SNR) of the DAS response was used for all the tests to evaluate the system performance. The results of the impact testing program indicated that the portions of the array in gravel performed more consistently over time. Changes in soil moisture or soil temperature did not appear to affect DAS performance. The results also indicated that time DAS performance does change somewhat over time. Performance variance increased in new portions of array in all material types through time. The SNR in portions of the DAS array in native silty sand material dropped slightly, while the SNR in portions of the array in sand fill and flowable fill material decreased significantly over time. This significant change in performance occurred while testing halted from March 2020 to August 2020 due to the Covid-19 pandemic. These significant changes in performance were observed in the new portion of test bed, while the performance of the prior installation remained consistent. It may be that, after some time in-situ, SNR in a DAS array will reach a steady state. Though it is unfortunate that testing was on pause while changes in DAS performance developed, the observed changes emphasize the potential of DAS to be used for infrastructure change-detection monitoring. In the temporary test bed, increasing vehicle loads were observed to increase DAS performance, although there was considerable variability in the measured SNR. The significant variation in DAS response is likely due to various industrial activities on-site and some disturbance to the array while on-boarding and off-boarding vehicles. The results of this experiment indicated that the presence of load on less than 10% of an array channel length may improve DAS performance. Overall, this dissertation provides guidance that can help inform the civil engineering community with respect to installation design recommendations related to DAS used for infrastructure monitoring.
