Estudo do cálculo de cargas móveis e linhas de influência no dimensionamento de pontes e viadutos / Study of the calculation of moving loads and influence lines in the design of bridges and viaducts

O principal sistema  logístico brasileiro passa pelas nossas rodovias e ferrovias , mais da metade das cargas transportadas utilizam-se desses meios para  o  movimento dentro do ciclo de produção , venda e consumidor. O tamanho do nosso País exige que distancias imensas sejam vencidas  para que matéria prima e bens acabados possam chegar a seus destinos . Pontes e viadutos  tornam-se elementos  fundamentais para tornar esta realidade mais confortável e segura . O estudo presente busca somar forças no sentido de facilitar a compreensão de dois conceitos muitos importantes para a análise e projeto dessas obras de arte da engenharia moderna que são linhas de influência e trem-tipos, a ferramenta de software Ftools foi usada com suporte  de verificação de cálculos , fazendo uso da norma  NBR 7118:2013 e  livros técnicos de engenheiros que atuam diretamente na área dando base ao presente trabalho

High fat and high cab diet effects on intramyocellular lipids, endothelial function and insulin resistance in young metabolic healthy overweight women

Dietas ricas em gordura ou carboidrato têm sido difundidas e consumidas nas últimas décadas, entretanto pouco é conhecido sobre as consequências metabólicas destas em longo prazo. Neste estudo, foram analisados a quantidade de gordura intramiocelular (IMCL), a função endotelial, além da lipemia, glicemia, insulinemia e resistência à insulina após semanas de dieta rica em gordura ou carboidrato, perdendo ou mantendo peso. De 43 mulheres triadas com sobrepeso (25< BMI <29.9 Kg/m2), 22 foram randomizadas para duas diferentes sequências de dietas. O IMCL foi medido através de espectroscopia por ressonância magnética 1H e a função endotelial pela pletismografia. Após 4 semanas de dieta rica em carboidrato, mantendo peso, foi observado aumento no IMCL do músculo tibial anterior (2.06 ± 1.27 vs. 3.52 ± 1.92, p=0.04) e na insulinemia em jejum (11.55 ± 4.43 vs. 14.03 ± 5.23, p=0.04), enquanto a dieta rica em gordura, no mesmo período, ocasionou aumento no HDL-C (37.06 ± 8.42 vs. 42.5 ± 9.32, p=0.003) e redução nos níveis de triglicerídeos em jejum (102,83 ± 34,10 vs. 75,83 ± 20,91, p=0,02). A função endotelial, colesterol total, LDL-C e resistência à insulina não mudaram durante esta fase. A perda de peso (média de 5%, por 8 semanas), não promoveu modificações nos parâmetros metabólicos vistos com a dieta de manutenção de peso. A partir destes resultados, concluiu-se que a ingestão de dieta rica em carboidrato, por 4 semanas de manutenção de peso, aumenta a insulinemia em jejum e o IMCL do músculo tibial anterior, enquanto a dieta rica em gordura pelo mesmo período aumenta o HDL-C e reduz triglicerídeos em mulheres saudáveis com sobrepeso.High fat or high carbohydrate (cab) diet have been widely difunded and consumed during last decades; however it is not clear their metabolic effects in long term. In the present study we analyzed intramyocellular lipids (IMCL), endothelial function, plasma lipids, glucose, insulin and insulin resistance after high fat or high cab diet during weeks, maintaining or losing weight. 43 overweight women (25< BMI <29.9 Kg/m2) were screened, 22 of them were randomized to two different diet sequence. IMCL was measured by using 1H magnetic resonance spectroscopy and endothelial function by using plethysmography method. Tibialis anterior IMCL (2.06 ± 1.27 vs. 3.52 ± 1.92, p=0.04) and fasting insulinemia increased (11.55 ± 4.43 vs. 14.03 ± 5.23, p=0.04) after four weeks of high cab diet after maintenance phase, while fasting HDL-C increased (37.06 ± 8.42 vs. 42.5 ± 9.32, p=0.003) and triglycerides levels decreased (102.83 ± 34.10 vs. 75.83 ± 20.91, p=0.02) after maintenance phase of high fat diet. Endothelial function, total cholesterol, LDL-C and insulin resistance did not alter during maintenance phase. A weight loss of 5%, after eight weeks, did not promote changes in the metabolic parameters, as seen during maintenance phase. Based on these results, it was concluded that high cab diet, four weeks with no weight change, increases tibialis anterior IMCL and fasting insulinemia, while high fat diet during same period increases HDL-C and decreases triglycerides in a healthy overweight women population
