(Universidade Federal de São Carlos, 2012-04-25) Pogetti, Lívia Silveira; Teixeira, Luis Augusto; https://lattes.cnpq.br/3456193961124925; https://lattes.cnpq.br/1009401301199185
This study aimed to evaluate the effect of visual occlusion of the preferred arm on its frequency of use and kinematics in spontaneous reaching of static objects in 5-month-old infants. Participated in this study 30 infants, with half of them submitted to visual occlusion of the preferred arm and the other half having full vision while reaching a toy. A possible cumulative effect of visual occlusion was assessed through increasing periods in which the preferred arm was not visible by the infant. Analysis of manual preference indicated that occlusion of the preferred arm led to increased use of the contralateral arm for reaching, an effect more evident in infants showing weak manual preference. No effect of cumulative occlusion was detected, with similar indices of manual preference across the periods of occlusion. Results from kinematic analysis revealed straighter movements to the target when visually oriented. These results suggest that visual information can modulate manual preference and guide reaching control.
Genética aplicada à ecologia de estradas: um estudo na estrada municipal Guilherme Scatena (São Carlos, SP) e potencial impacto na biodiversidade local
(Universidade Federal de São Carlos, 2012-04-25) Rodriguez Castro, Karen Giselle; Galetti Júnior, Pedro Manoel; https://lattes.cnpq.br/7398754661670478; https://lattes.cnpq.br/0505422022027092
Roads generate a large ecological impact to wildlife by raising barriers among ranges of species originally continuous and for causing road-kills. After road-killing, a morphological identification becomes impossible for the loss of diagnostic features, especially in the case of small vertebrates. Use of molecular tools for identification is an alternative that has shown successful results, especially when looking towards the species level. We identified samples from animals road-killed, collected on Guilherme Scatena road, through the use of DNA barcode markers, contributing to the local biodiversity knowledge. Another objective was to know the places that have a higher incidence of road kill and the type of landscape coverage in them. During 20 weeks we collected 123 vertebrates: six mammals (5% of total), 30 birds (24%), 38 amphibians (30%) and 49 reptiles (40%), which meant an average of 0.051 animals/Km road-killed. Through morphological characteristics and molecular (mitochondrial genes cox1 and 16S) we identified 111 samples until species status. Analyses among taxonomic classes showed significant differences, confirming that the effects of roads on biodiversity are taxon-specific. We found 19 different types of landscape around the road, being the most common farm buildings and pasture, showing the strong anthropic pressure on environments of this region. The results shown in this study are intended to be an important basis for planning future actions that provide the best management of this area rich in endemic biodiversity of the Brazilian cerrado, as well as mitigation measures to lessen the impact caused by the road.
Avaliação das inter-relações entre função cardiopulmonar e mediadores inflamatórios no diabetes mellitus
(Universidade Federal de São Carlos, 2012-04-25) Francisco, Cristina de Oliveira; Leal, Ângela Merice de Oliveira; https://lattes.cnpq.br/7202663545989206; https://lattes.cnpq.br/7665896448082766
Diabetes Mellitus (DM) is associated with many complications, including impairment of cardiorespiratory fitness and pulmonary function. Increasing evidences has suggested that comorbidities and systemic inflammation may be involved. The objective of this study was to evaluate cardiorespiratory function in rest and exercise in adults with DM and to verify the relationship between inflammation. Nineteen men with diabetes (51,16 years ± 5,92) and nineteen control subjects (48,79 years ± 7,47) were studied. All individuals were subjected to incremental cardiopulmonary exercise test in cycle ergometer, spirometry, intracellular cytokine lymphocyte profile, lipid and c-reactive protein (CRP) plasma concentration. In the exercise test, maximal overload (W), peak heart rate (HRpeak), oxygen consumption at peak (VO2peak) and at anaerobic threshold (VO2AT), respiratory exchange ratio (RER) were significantly lower in patients with DM than in control subjects. Control subjects and individuals with DM were not different in age, blood pressure, lipid and CRP plasma concentration and intracellular cytokine lymphocites production of TNF-α, IFN-γ, IL-4, IL-10 e IL-17. No significant differences were noted in pulmonary function variables, but abnormalities in these data were predictors to DM. In conclusion, the results confirm impairment of the cardiopulmonary fitness in subjects with DM. The inflammation associated with DM might be influenced by other factors absent in our sample. In addition, the data suggest spirometric abnormalities as predictive to diabetes mellitus.
Inovações na produção de hidrolisados de soja: modelagem e análise econômica de processo
(Universidade Federal de São Carlos, 2012-04-25) Pretto, Cristine De; Costa, Caliane Bastos Borba; https://lattes.cnpq.br/1602653870311562; https://lattes.cnpq.br/6766872282137948
Soybean and its derivatives have the desired properties for food either for humans or various animals because of its high protein content, which is associated to a good balance of amino acids. However, when the protein is hydrolyzed into smaller peptides, the nutritional value can increase further. A product with high nutritional value added but which does not present economic viability is not interesting for the industry. To analyze such viability, there are softwares that simulate and analyze a process plant. Thus, this study is two-fold: the mathematical modeling of the hydrolysis process and a preliminary analysis of economic viability. Concerning the modeling, two models were fitted: one that relates time with the degree of enzymatic hydrolysis of proteins of concentrated soybean meal and another that relates the degree of hydrolysis with the molecular weight distribution of the pseudocomponents. The analysis of economic viability was conducted using software SuperPro Designer. For this purpose, a degree of hydrolysis and its molecular weight distribution was chosen, and then, an industrial plant was modeled and simulated in a preliminary project level. For the kinetic model, hydrolysis was conducted in laboratorial scale, using a pHstat and an enzyme called Novo-Pro D. The product was analyzed by liquid chromatography. The data were analyzed and the ones obtained in the best conditions were used to fit the model. The best conditions were 55oC, pH 9, 90% humidity, 0,5% m(enz/sub). The kinetic fitting was well described by the Michaelis-Menten with competitive inhibition and neural network described with high fidelity the relation between the concentration of the pseudocomponents and the degree of hydrolysis. Regarding the analysis of the preliminary project of an industrial plant for the production of hydrolyzed protein of concentrated soybean meal, the plant was economic viable, but the project is in a very preliminary stage, due to a lot of unknown data so they were estimated increasing the uncertainty of results.
A Escola de Sargento das Armas: um estudo sociopolítico sobre a formação de praças do exército
(Universidade Federal de São Carlos, 2012-04-25) Atassio, Aline Prado; Villa, Marco Antonio; https://lattes.cnpq.br/7695077592581355
This research aims at finding out about the perspectives of the future sergents of the Armed Force, graduated by the Escola de Sargento das Armas (EsSa). There are few studies about sergents within the Brazilian Social Science, therefore the importance of this research. Among the general focus of this research are the sergent history, their academic education within time and the quotidian os EsSa studentes. The study presents statistics that aims at showing the students´ social origin and interviews that present thestudents´ history and their longing about their career. We have used several scientific methods to conclude this theses, such as bibliographical research, semi-directed interviews, statistics and field research. The result has showed that most of the sergents are from low class families, from the south and south-west parts of Brazil, with age rate between 19 and 25 years-old, without militares parents and high-scholl graduated. However, they don´t show either greater oportunities of advance in theis studies neither possibilities of garantee a career outside the Arm. This confirms the theses that the Arm is used, historically, as a mean of social scaling form those that are in the lower part of Brazilian social pyramid.
