title: Influence of tribological test on the global conversion of natural composites

description: Abstract The vinyl ester resins and natural composites have emerged as a suitable alternative in tribological application due to mechanical behavior, which relates to the conversion of the double bonds. During tribological test the permanent contact between polymeric sample and counterpart can increase the temperature affecting the crosslinking of the samples. These variations have direct implications in the curing rate and the global conversion. In this work, the FTIR evaluation is used to evaluate possible changes on the global conversion of vinyl ester and their composites reinforced with Musaceae fiber bundles and cured using two hardeners, after a specific tribological test. Increments around 15% on global conversion of styrene double bonds were observed for neat matrix and composites using both hardeners, suggesting that during tribology test some alterations on resin structure takes place. These results open alternatives to manipulate the curing conditions in order to control the tribological behavior.

title: Coding pulmonary sepsis and mortality statistics in Rio de Janeiro, RJ

description: ABSTRACT: Objectives: This study aimed to describe "pulmonary sepsis" reported as a cause of death, measure its association to pneumonia, and the significance of the coding rules in mortality statistics, including the diagnosis of pneumonia on death certificates (DC) with the mention of pulmonary sepsis in Rio de Janeiro, Brazil, in 2011. Methods: DC with mention of pulmonary sepsis was identified, regardless of the underlying cause of death. Medical records related to the certificates with reference to "pulmonary sepsis" were reviewed and physicians were interviewed to measure the association between pulmonary sepsis and pneumonia. A simulation was performed in the mortality data by inserting the International Classification of Diseases (ICD-10) code for pneumonia in the certificates with pulmonary sepsis. Results: "Pulmonary sepsis" constituted 30.9% of reported sepsis and pneumonia was not reported in 51.3% of these DC. Pneumonia was registered in 82.8% of the sample of the medical records. Among physicians interviewed, 93.3% declared pneumonia as the most common cause of "pulmonary sepsis." The simulation of the coding process resulted in a different underlying cause of death for 7.8% of the deaths with sepsis reported and 2.4% of all deaths, regardless the original cause. Conclusion: The conclusion is that "pulmonary sepsis" is frequently associated to pneumonia and that the addition of the ICD-10 code for pneumonia in DC could affect the mortality statistics, highlighting the need to improve mortality coding rules.

title: Acute Onset Neurological Disorders during Pregnancy: A Literature Review

description: Abstract Objectives To characterize the most common peripheral and central neurological disorders during pregnancy. Methods Original research and review of the literature on neurological complications during pregnancy. We searched for keywords related to the topic on different databases. Results Pregnancy involves physiological changes that can trigger peripheral neurological and/or central nervous system pathologies, which can sometimes be associated with hypertensive disorders. A definitive diagnosis of neurological disorders can be made according to the trimester of pregnancy and the clinical findings. Carpal tunnel syndrome and peripheral facial palsy are common peripheral neurological disorders, more frequent in the second half of pregnancy. Central nervous disorders are more complex and a precise diagnosis must be made in order to improve perinatal outcomes, provide correct management and treatment and to prevent acute and long-term complications. Conclusions It is possible to achieve a precise diagnosis,management and treatment of neurological disorders during pregnancy, but these require a multidisciplinary approach, crucial to improve perinatal outcomes.

title: Influence of Pellet Compaction Pressure on the Physical Properties of La0.7Ba0.3MnO3 Manganite

description: Perovskite manganite La0.7Ba0.3MnO3, synthesized by ionic coordination reaction method (ICR) was compacted into pellets under different compaction pressures (Pc) and sintered at a temperature of 1150°C for 10h under a flow of O2. X-ray diffraction (XRD) data reveal that the samples can present simultaneously two phases - a rhombohedral structure with space group R3c and an orthorhombic structure with space group Pnma. Scanning electron microscopy (SEM) images show that, for this sintering temperature, the particle size and shape can be modified depending on the compaction pressure (Pc). Magnetization measurements show that the saturation magnetization and Curie temperature increase with Pc. The enhancement of the ferromagnetic properties of perovskite manganites La0.7Ba0.3MnO3 as a function of the compaction pressure is explained by an increase in the rhombohedral/orthorhombic structure ratio caused by this effect.

title: VEGETATIVE STAGE OF STRAWBERRY DURATION DETERMINED BY THE CROP YEAR

description: ABSTRACT Over the years, strawberry growth has shown alterations in its phenology, involving mainly the beginning of flowering and fruiting. The aim of this study was to verify whether the growth years influence the duration of strawberry vegetative and reproductive stages in protected environment. The development of the Camarosa strawberry cultivar was observed between 2007 and 2014. The crops were settled in a greenhouse in the Horticulture Sector at the University of Passo Fundo, RS. Data like transplant date, in the beginning and end of the fruits harvest; temperature data (maximum, average and minimum) were recorded in the growth environment. These data were used for the thermal sum calculation (daily, accumulated). The data analyses were carried out in a descriptive manner, relating the temperature data with the phenological stage of each year. The accumulated thermal sum that is necessary to begin the harvest was variable throughout the years, where it was between 383 and 438 degrees days-1 for plants with interval between transplant and harvest of 73 days (2008 and 2009) at 816 degrees days-1, where the interval was 111 days (in 2014). In the first case, it accumulated 5.2 ºC/day, in 2008 and 6 ºC/day, in 2009. In the second case, it was 7.3 ºC/day, in 2014. Seedlings which were transplanted in the first fortnight of May began fruiting in the beginning of August and September. Seedlings transplanted in July 2011 and 2012 began fruiting in similar periods, that is, in the first and second fortnight of September. It was found that, because of the temperatures recorded in different periods of growth and transplant time, there is alteration mainly in the strawberry vegetative stage.

title: Effect of Feeding Transcarpathian Zeolite on Gastrointestinal Morphology and Function in Broiler Chickens

description: ABSTRACT Many kinds of feed additives can be used in chicken diets to stimulate intestinal morphological maturation and, consequently, intestinal function. The purpose of this study was to evaluate the effect of zeolite on broiler performance, gut morphology and gut digestive enzyme activity. The one-day old broiler chickens Ross 308 were assigned randomly into 3 groups with 30 birds per treatment. The 3 dietary treatments were: basal diet only (control group), basal diet + 2% zeolite, basal diet + 3% zeolite. Morphological and morphometric intestinal assessments were conducted using a light microscope. There was observed increase in villus height, villus perimeter, villus section area and crypt depth throughout duodenum and mid jejunum of the broilers fed zeolite. Supplementation especially with 2% zeolite was associated with greater villus heights, villus perimeter, villus section area and crypt depth in duodenum and ileum mucosa compared to the controls. The diet with 2% zeolite also contributed to significant increase proventriculus (pepsin) and pancreas (trypsin, lipase) activity compared to the controls The results suggest that dietary supplementation of zeolite increased feed consumption, intestinal morphology parameters and enzyme activity of gastrointestinal tract in broiler which improved growth performance.

title: Teacher Motivation Scale: development and validation

description: ABSTRACT This study’s main objective was to analyze psychometric evidence of validity and reliability of a Teachers Motivation Scale (EMD, Escala de Motivação Docente), in order to explore self-determined motivation exhibited by teachers. This scale was constructed in advance by the research group, and was developed based on the Self-Determination Theory (SDT), which approaches self-determined motivation as an intrinsic process, influenced by social context, taking into account basic psychological needs such as autonomy, competence and sense of belonging. After semantic and content analysis of all scale’s items and once a pilot test was performed, a preliminary version of the EMD scale was applied to 398 Brazilian faculty members. These exploratory results led to the refinement of the scale. The prototype version of this EMD is now composed of twenty-four Likert items and embraces five dimensions: Performance, Personal Development, Teaching Practice, Continued Education and Institutional Insertion. The factorial analysis showed good internal consistency, confirming the proposed structural model. Although preliminary, the current results provide consistent evidence for the validity of the EMD construct and seem promising for studies related to teachers’ motivational evaluation. It is recommended, however, that other validity studies which corroborate and amplify current findings be pursued.

title: Case Study in Jagua Bay at South of Cuba Using a Coupling WRF/CALMET

description: Abstract CALMET meteorological model was evaluated during a typical period of dry season in a coastal domain in the Jagua bay at the south of Cuba, for TERRAD parameter. Several resolutions and four different CALMET input datasets were used. The evaluation was focused in terms of model performance of wind and surface temperature issues. As input data, the WRF model results and meteorological measurements of different stations were combined. WRF model surface speed results has been significantly improved by CALMET model. A slightly improvement is obtained with resolution increasing. A high value of TERRAD of 80 km was obtained as the best fit for this parameter that matches with the domain size. The statistical results (both relative and absolute) were calculated on the stations that were not used as input data. Statistical relative values of wind speed were high, due to weak winds over the study period. However, the absolute ones were better. Significant improvement was also observed in wind speed and temperature for relative and absolute statistical values, when more stations as input data were provided.

title: BUILDING COLLABORATION? CO-LOCATION AND “DIS-LOCATION” IN A RAILWAY CONTROL POST

description: ABSTRACT This paper studies the design of co-located spaces and how organizational actors experience such spaces. The literature on co-location is ambiguous about how reduced physical distance increases collaboration. To address this problem, we draw on an ethnographic study of a co-located railway control center, housing the largest Dutch railway organizations under one roof. Although the intention of the co-location was to improve collaboration by bringing different organizations into closer proximity, our findings tell a different story. Railway employees developed several territorial practices (preserving existing boundaries, creating new boundaries, and the situational use of boundaries) through which they resisted the design of the control center, thereby changing the control center from co-located to “dis-located.” We argue that understanding the relationship between co-location and collaboration should not only focus on how such spaces are designed but, rather, account for how spaces where collaboration is demanded are experienced and used by employees.
