title: MOISTURE SORPTION ISOTHERMS OF QUINOA SEEDS: THERMODYNAMIC ANALYSIS

description: ABSTRACT The present research aimed to study the water sorption behavior of quinoa seeds analyzing the hysteresis phenomenon and determining thermodynamic properties. Static gravimetric technique was used to obtain the equilibrium moisture content of quinoa seeds in different temperature conditions (15, 25, 35 e 50 °C) and relative humidity (between 11 and 96%). Equilibrium moisture content data were adjusted by eight mathematical models and the Modified Halsey model was the best one to describe the water sorption phenomena of quinoa seeds. Hygroscopic equilibrium moisture content of quinoa seeds is directly proportional to the water activity and decreases with increasing temperature. The hysteresis phenomena were observed throughout the range of water activity, showing more evident at low temperatures. Integral isosteric heat and differential entropy decreased with the increase of equilibrium moisture content. Gibbs free energy decreased with the increase of temperature and equilibrium moisture content. Compensation enthalpy-entropy theory was confirmed and the sorption mechanism is controlled by enthalpy.

title: Association between depressive syndrome and visual complaints among elderly caregivers

description: ABSTRACT Objectives To determine depressive syndrome in community-dwelling elderly caregivers; and to test the association between such syndrome and both visual complaints (VC) and aspects of care. Methods This is a cross-sectional study conducted with 332 elderly caregivers. Geriatric Depression Scale (GDS-15) was used to screen for depressive symptoms (cutoff &gt; 5 points). Logistic regression was performed to identify associations between depression and both VC and aspects related to care. Results Median age of the caregivers was 68 years. The majority was female (75.9%) and took care of a spouse (84.3%). The prevalence of depressive syndrome was 22.6%. The syndrome was associated with VC when it affected activities of daily living (OR = 2.4; 95% CI: 1.37-4.27) and caring for an individual with cognitive impairment (OR = 1.85; 95% CI: 1.05-3.26). Conclusions While measured aspects of care did not exert an influence on the incidence of depressive symptoms, VC associated to functional limitation and caring for elderly individuals with cognitive impairment was associated with such symptoms in the elderly caregivers.

title: STATITIONARY ENGINE PERFORMANCE USING MIXTURE OF SOYBEAN AND CASTOR BEAN BIODIESEL TO DIESEL OIL

description: ABSTRACT The use of alternative fuels in diesel engines has been the subject of research that seeks new fuels to expand the energy matrix. The aim of this study was to evaluate the performance of the stationary engine with the use of mixtures of biodiesel from soybean and castor bean added to diesel (S500) in two proportions (25% and 40%), evaluating the torque, effective power observed and specific consumption. The five biodiesel mixtures of soybean (S) and castor bean (C) analyzed were: S100C0, S75C25, S50C50, S25C75 and S0C100, which were added to the diesel in proportions B25 and B40, totaling ten treatments, plus the control with diesel S500 (B7). The stationary engine was subjected to the rotations of 3000, 2700, 2400, 2100, 1800 and 1500 rpm. The performance of the engine was similar for all biodiesel mixtures of soybean and castor bean, and commercial diesel (B7). The B40 S100C0 and B40 S75C25 provide better performance in terms of effective power observed and torque at 2700 rpm. The highest effective maximum power (3000 rpm) was obtained with the use of B7 diesel. In the lower rotations, it was possible to identify a similar performance result of the biodiesel mixtures with the B7, in addition to providing better torque and consumption performance compared to the commercial diesel.

title: Metabolizable Energy Levels for Meat-Type Quails at Starter Phase

description: ABSTRACT This experiment was conducted to evaluate the effects of dietary nitrogen-corrected apparent metabolizable energy (AMEn) levels on meat-type quail performance and carcass traits from 1 to 14d of age. A total of 1120 not sexed meat-type quails were randomly distributed to seven treatments, with eight replicates with 20 quails each. A basal corn and soybean meal-based diet was formulated to meet or exceed quail nutritional requirements, except for ME. Graded levels of soybean oil were added to the basal diet in replacement, to sand, to obtain dietary treatments (2,600; 2,700; 2,800; 2,900; 3,000; 3,100 and 3,200 KcalAMEn/kg diet). Data were analyzed as one-way ANOVA and optimum AMEn levels were estimated using polynomial regression model. Increasing in dietary AMEn levels elicited a linear decrease (p&lt;0.01) in feed intake and nutrient intake (AMEn, protein and lysine). Quail weight gain and final body weight exhibited a quadratic response (p&lt;0.03) to increased AMEn levels, being both optimized at 2820 KcalAMEn/kg diet. Graded AMEn levels elicited a linear increase (p&lt;0.01) in carcass dry matter and fat content, whereas moisture content was linearly decreased (p&lt;0.01). The protein content of the carcasses was not influenced (p&gt;0.05) by AMEn. Based on the results, the dietary AMEn level that warrants adequate performance and carcass traits of meat-type quails from 1 to 14d of age is 2,820 Kcal/kg diet.

title: Modelos Computacionais para Verificação de Identidades Polinomiais em Álgebras de Matrizes com entradas na Álgebra de Grassmann

description: ABSTRACT In this paper is presented a computational approach to deal with algebras that satisfy polynomial identities. More precisely, we used the Maple program to verify and identify polynomial identities of matrix algebras with entries in the Grassmann algebra E, especially the algebra M k,l (E), which Di Vincenzo and La Scala showed interesting results when k = l = 1, using the notion of weak polynomial identities. Some procedures were created in Maple to suit the product of the matrices according to the properties of E, this being a non-commutative algebra. In addition, we implemented some functions with shorter processing time in solving certain problems compared to similar Maple functions. It should be noted that we use the Maple version 18 on a computer with Intel @ Core i7 and 8GB of RAM memory. We conclude with a study of the conjecture given by Kemer at about the minimum degree of the standard polynomial for the algebra M n (E).

title: He who ignores the past is doomed to repeat it: distortions of postgraduate evaluation in Brazil based on Capes’ history

description: Abstract This paper aims to highlight some distortions in the Capes evaluation system, particularly in the area of Administration, Accounting and Tourism, starting from the history of Capes in Brazil. Through this analysis, it was possible to conclude that the change in the assignment of grades from 1 to 5 to 1 to 7 in the 1990s was not followed by a change in the Capes evaluation system, which still uses scores from 1 to 5 to evaluate the programs in each of their requirements. Such distortion becomes incompatible with an evaluation system that is summative and classificatory. As a consequence, productivity is confused with productivism, methodological rigor for the evaluation of programs is jeopardized, and the educational character of a formative evaluation is abandoned.

title: Artemisia Annua as Phytogenic Feed Additive in the Diet of Broilers (14-35 Days) Reared under Heat Stress (32 ºC)

description: ABSTRACT The 21 days feeding trial was conducted on 90, Cobb 500 broilers (aged 14 days), assigned to 3 groups (C, E1 and E2) housed in an experimental hall at 32° C constant temperature and 23 h light regimen. During the growth period (14-35 days), the conventional diet (C) had corn and soybean meal as basic ingredients. Unlike the conventional diet formulation (C), the diet formulations for the experimental groups also included 0.005% Artemisia annua oil (E1) and 0.005% Artemisia annua oil plus 1% Artemisia annua powder (E2). Six broilers per group were slaughtered at 35 days of age in order to measure the weight of the carcass and internal organs of broilers, and samples of intestinal and caecal content were collected for bacteriological assessment (Enterobacteriaceae, E. coli, staphylococci, Lactobacilli, Salmonella spp.).The following parameters were monitored during the experimental period: bodyweight (g); average daily feed intake (g feed/broiler/day); average daily weight gain (g/broiler/day); feed conversion ratio (g feed/g gain). Under heat stress (32 ºC), E2 broilers (mixture of A. annua oil and powder) had a significantly (p&lt;0.05) higher average of daily feed intake than the broilers receiving the C diet or the diet supplemented just with A. annua oil (E1). Both samples of intestinal and caecal content, showed the lowest count (p&lt;0.05) of Enterobacteriaceae, E. coli and staphylococcus colony forming units in E2 broilers. Diet with A. annua oil and powder provided proper conditions for lactic acid bacteria proliferation in the intestine and caecum of heat stressed broilers.

title: Executive Function Performance Test: transcultural adaptation, evaluation of psychometric properties in Brazil

description: ABSTRACT Executive dysfunction occurs in 18.5% to 39% of patients who present with cognitive impairment. Occupational therapy aims to facilitate independence and autonomy, hence improving quality of life. The Executive Function Performance Test – Brazilian version (EFPT-BR) has been developed to assess the need for assistance in performing four basic daily tasks. Objectives: The aims of this research were: (1) to offer cross-cultural adaptation in patients with stroke; (2) to assess the psychometric properties of the Brazilian version of the EFPT-BR in patients with stroke; (3) to assess the relationship between scores on the EFPT-BR in patients with stroke, and demographic variables, stroke location, symptoms of anxiety and depression. Methods: The transcultural adaptation and validation were performed based on standard procedures, and psychometric properties were assessed in 86 Brazilian patients who suffered a stroke. Results: The test has shown a good internal consistency (Cronbach's alpha: 0.819). The ICC for intra-rater reliability was 0.435 and for the inter-rater was 0.732. Significant correlations between scores in the EFPT-BR and executive measures (verbal fluency test, clock drawing test, digit span – forwards and backwards, zoo map test and Six Elements Test) were observed. Conclusion: The EFPT-BR is a valid and reliable tool for occupational therapists to assess executive dysfunction in daily routine tasks in patients with stroke in Brazil.

title: BsmI polymorphism in the vitamin D receptor gene is associated with 25-hydroxy vitamin D levels in individuals with cognitive decline

description: ABSTRACT Elderly people are at a high risk of developing vitamin D (VitD) deficiency due to both decreased intake and cutaneous synthesis. Most of the biological actions of VitD are mediated by the vitamin D receptor (VDR), which is present in neurons and glial cells of the hippocampus, and in the cortex and subcortical nuclei, essential areas for cognition. It is known that VDR gene polymorphisms may decrease the VDR affinity for VitD. Objective: The present study aimed to investigate the influence of VitD levels on cognitive decline in patients with dementia due to Alzheimer's disease (AD, n = 32) and mild cognitive impairment (MCI, n = 15) compared to cognitively healthy elderly (n = 24). We also evaluated the association of VDR gene polymorphisms with cognitive disturbance. Methods: Four polymorphisms on the VDR gene were studied, namely, BsmI, ApaI, FokI and TaqI, by polymerase chain reaction-restriction fragment length polymorphism. Serum levels of 25-hydroxy vitamin D (25(OH)D) were determined by high performance liquid chromatography. Results: No significant difference in 25(OH)D levels or genotypic/allelic frequencies was observed between the groups. Deficiency of 25(OH)D was more frequently observed in women. The AA/AG genotypes of the BsmI polymorphism was associated with sufficient 25(OH)D levels, while the GG genotype of this same polymorphism was associated to insufficient levels in the cognitively-impaired group (individuals with AD or MCI). Conclusions: The data obtained do not confirm the relationship between reductions of VitD levels, polymorphisms in the VDR gene, and altered cognitive function in this sample. However, the data indicate that BsmI polymorphism in the VDR gene is associated with the VitD levels in individuals with cognitive decline.
