title: Multiband FSS Analysis and Synthesis Based on Parallel Non Coupled Metallic Strips Using WCIP Method

description: Abstract A novel parallel non coupled metallic strips frequency selective surface (FSS) is presented. The design is based on a filter composed of horizontal and vertical metallic strips. The structure has the advantage of simplicity and gives multi resonant frequencies easily controlled by a simple variation in the strips length. The proposed FSS rejects frequencies at 7GHz, 9.4GHz with bandwidths of 0.646GHz, 0.793GHz respectively when the structure is excited with an x polarized plane wave, and two frequencies at 9.1GHz and 11.2 GHz with bandwidth of 280.3MHz, 63MHz respectively when the structure is excited with a y polarized plane wave. To suppress frequencies ideal diode on reverse bias are inserted. The simulated results obtained using WCIP (Wave Concept Iterative Method) are compared to the COMSOL Multiphysics 4.3b software results, and measurements, a good agreement is observed. Then, an FSS synthesis approach based on non coupled parallel metallic strips is presented. It provides synthesized FSS with resonant frequencies ranging from 4.5GHz and 12.25 GHz for metallic strips lengths inversely varying from 5mm to 19mm. To validate the synthesis approach, measured resonant frequencies are used as desired resonant frequencies to determine the metallic strips lengths. As a result the metallic strips FSS dimensions are extracted. At this stage the WCIP method is used to characterize the synthesized FSS. Three FSSs are synthesized based on the fabricated FSS and good agreement between measurements and synthesized FSSs results is recorded.

title: Diversity of yeasts during fermentation of cocoa from two sites in the Brazilian Amazon

description: ABSTRACT The purpose of this study was to identify the yeasts involved in spontaneous fermentation of cocoa from the Brazilian Amazon region. The fermentation process was carried out experimentally with cocoa seeds from two sites (Medicilândia and Tucumã), State of Pará, northern Brazil, during a six-day period. Totals of 44 yeasts were isolated from Medicilândia and 29 from Tucumã. Molecular identification was carried out by sequencing the D1/D2 region fragment of the rRNA 26S gene, expanded with universal primers for the NL1GC and LS2 eukaryotes. Pichia manshurica and Saccharomyces cerevisiae were identified in Medicilândia and five yeast species (Pichia fermentans, P. kudriavzevii, P. manshurica, S. cerevisiae and Zygosaccharomyces bailii) were identified in Tucumã. The results showed that P. manshurica and S. cerevisiae may have potential for use as starter cultures in future studies to improve the quality of cocoa seeds fermented in the Brazilian Amazon region.

title: Sample transport validation: experience of a medium-sized laboratory

description: ABSTRACT INTRODUCTION: The adequacy of biological samples is a critical and important item in the clinical laboratory, so that reliable results can be obtained for patients. OBJECTIVE: To ensure integrity and stability of biological samples during the transport process. METHOD: Concurrent validation was carried out – in parallel with the production process and distribution of the product, from January to March 2017. The blood samples were packaged primarily in tube racks, and those of urine, feces and microbiological materials were packed in plastic bags. Materials were wrapped in a blanket of absorbent material to ensure temperature integrity and to avoid possible material losses. Thermal bags were the containers used to carry the samples. There were five transport routes, with two daily routes for each collection unit. A recommendation of the number of ice packs, predefined by the laboratory, was followed. RESULTS AND CONCLUSION: In the first month, the pre-established temperatures (blood: 10°C to 22°C/urine-feces: 2°C to 8°C) were not reached until arrival at the central laboratory, and the amount of ice in each bag was gradually increased, daily, until reaching the ideal temperature, in all collection units and the central. Transport routes were changed three times in the most distant units. Materials that arrived outside specifications were processed with restrictions, and results were evaluated by the professional responsible for the release. After these modifications, the temperature records of the biological materials were in accordance with the current legislation and the defined specifications, thus validating the process.

title: Fuzzy logic in automation for interpretation of adaptability and stability in plant breeding studies

description: ABSTRACT: The methods of Annicchiarico (1992) and Cruz et al. (1989) are widely used in phenotypic adaptability and stability analyses in plant breeding. In spite of the importance of these methodologies, their parameters are difficult to interpret. The aim of this research was to develop fuzzy controllers to automate the decision-making process employed by adaptability and stability studies following the methods adopted by Annicchiarico (1992) and Cruz et al. (1989) and check their efficiency using experimental data from common bean cultivars. Fuzzy controllers have been developed based on the Mamdani inference system proposed by these two methods of adaptability and stability studies. For the first fuzzy controller parameters were considered favorable environments and the recommendation index for unfavorable environments obtained by Annicchiarico's method (1992). For the second controller the parameters considered were the general mean (β0), coefficient of regression of unfavorable environments (β1) and coefficient of favorable environments (β1i + β2i) and the coefficient of determination of the method of Cruz et al. (1989). To check the performance of these drivers yield data from field trials on 18 common bean cultivars grown in 11 environments were used. The controllers were developed from established routines in the R software and, using the inference system based on the methods proposed by Annicchiarico (1992) and Cruz et al. (1989), classified the 18 genotypes appropriately in accordance with the criteria for each method. Thus, the methods used are effective, and are prescribed for decision-making automation in yield adaptability and stability studies pertaining to recommendation of cultivars.

title: Use of vitamin D and infection in patients with chronic kidney disease

description: ABSTRACT Objective: To evaluate the effectiveness of vitamin D supplementation as protection factor against infection of patients with chronic kidney disease on conservative treatment. Method: Retrospective cohort study carried out between 2013 and 2016 in the Conservative Treatment Outpatient Clinics (Ambulatório de Tratamento Conservador) of the Hypertension and Kidney Hospital (Hospital do Rim e Hipertensão) of the Universidade Federal de São Paulo. Data on sociodemographic factors, comorbidity, infection episodes and use or nonuse of vitamin D supplementation for at least 6 months were collected from medical records. The primary outcomes considered in both groups were: presence or absence of infection anywhere on the body (bloodstream, urinary, respiratory and surgical sites). Results: A total of 263 patients were included and those who received (n=43) vitamin D had 59% less chance of developing infections (OR=0.41; 95%CI; 0.15-0.99), when compared to those who did not receive. Conclusion: Vitamin D supplementation was a protective factor against infections of all causes.

title: Comparison of different household food security assessment methods in the rural area of a Brazilian city

description: Abstract Aim:To evaluate and compare household food security situations in the rural area of a Brazilian city by three different methods: Availability of food energy at home, nutritional status and Perception of food insecurity. Methods: Cross-sectional study of 79 families living in 19 rural communities in a small city in Minas Gerais, Brazil, including a total of 272 residents. Families were selected by drawing lots, respecting the proportionality of families per community. The inclusion criteria included living in rural areas, inhabiting a selected household, and using food products available for consumption, by purchase and production. During family visits, nutritional status was analyzed by anthropometry, the perception of food insecurity by Food Insecurity Scale (EBIA) and availability of food energy at household for 30 days. Results: Of the 79 families of family farmers, 12.7% were considered to be unsafe for availability of food energy at household, 24.0% due to the presence of low weight at the household and 49.5% by EBIA. There was a low correlation among the methods, with differences between them (Kendall W 0.162 p &lt;0.001). Food insecurity was associated to the presence of at least one individual aged less than 18 years old in the household. Food security classified according to EBIA was associated with an increase in the number of people living in the household, the production of vegetables and fruits. Conclusions: No single indicator can cover several dimensions of food security. Food Security involves a broad and multifaceted approach; therefore, its thorough evaluation requires different classification methods.

title: Variation in temephos resistance in field populations of Aedes aegypti (Diptera: Culicidae) in the State of Sergipe, Northeast Brazil

description: Abstract INTRODUCTION The organophosphate temephos was first used in Brazil in the 1960s for the control of Aedes aegypti. Because of its extensive and longstanding use worldwide, selection for mosquito populations resistant to the chemical has been observed not only in different regions of Brazil but also in several parts of the world. The objective of this study was to evaluate the susceptibility of Ae. aegypti to the organophosphate temephos, a larvicide used in vector control activities in Sergipe/Northeast Brazil. METHODS This study included mosquito populations from seven municipalities of Sergipe and was carried out from October 2010 to August 2011. Qualitative bioassays of diagnostic dose and dose responses were performed. The resistance ratio was calculated based on lethal concentrations for mosquitoes of the susceptible Rockefeller strain. RESULTS: All populations were classified as resistant to temephos. The resistance ratio ranged from 22.2 to 297.9, the lowest being seen in Aracaju, a coastal area of the state, and the highest in Pinhão, a semi-arid region, 96.6km from Aracaju. CONCLUSIONS: High levels of temephos resistance were observed in the Ae. aegypti populations of Sergipe. The variation between regions indicates that there have been different regimes of insecticide use and also points to the potential of small cities to generate and spread insecticide resistance.

title: Interactional strategies used by university students of Italian as a foreign language (IFL) at basic or advanced levels during symmetric conversations

description: ABSTRACT This paper discusses the development of interactional competence in the light of conversational studies. More specifically, the focus will be on the use of discourse markers in semi-guided conversations with learners of Italian as a foreign language (FL). The study has been carried out with university students enrolled in the first and last year of the Undergraduate Course in Italian at the University of São Paulo in Brazil. The heavy presence of agreement discourse markers combined with the sporadic use of competitive interruptions and metatextual discourse markers indicate that the students are not predisposed to a culture of discussion. This result was found both at beginner and advanced levels. Despite some difficulties in managing communication, expressed through hesitation, vertical constructions and requests for help, the informants do not withdraw from the task at hand and do everything they can to maintain the conversation flow. The variety of discourse markers in learners’ interlanguage is essentially the same at both levels, except for agreement discourse markers, which are more varied at the advanced level, and phatic expressions, which are used exclusively at the beginner level. These data lead us to assume that higher levels of competence do not necessarily result in the use of a wider range of discourse markers. Other factors are likely to have influenced learners’ interlanguage, such as the type of input learners were exposed to, as well as their engagement in tasks which required them to notice specific language forms. From a pedagogical point of view, it emerges that suitable observation and production activities should be used from the beginner levels, as these tasks help raising learners’ consciousness about those conversational mechanisms which regulate discussions among native speakers.
