Análise e simulação de modelos matemáticos para a estimativa da geração de gases em bioprocessos de decomposição anaeróbia de resíduos sólidos em aterros sanitários

Brazil faces a complex problem in respect to municipal solid waste, having been in recent years an increase of its generation without the country there be adequate for proper disposal thereof. In many states , the percentage of waste destined improperly , ie , in dumps , landfills, send- outs , among others , is greater than that disposed in landfills , which would be the most correct way to be made. It can be argued that this discrepancy is due to the high cost of implementation and operation of the landfill, and the same need large areas with physical characteristics that suit their operations . When there is a provision in properly constructed landfills , municipal solid waste grounded generate gases with high potential energy through biochemical reactions during the anaerobic decomposition of organic material stored . Such gases can be used for power generation within the landfill or other economic means . To estimate the gas generation will be sufficient for such economic compensation , there are mathematical models that make estimating the amount of gas produced . These models calculate the energy capacity and generation , using parameters obtained based on the characteristics of solid waste , climate of the region where they are grounded and grounding time . Such models have been raised and studied so that it was possible to perform simulations that demonstrate the behavior of biogas generation related to the external conditions of the landfill that interfere with biological reactions within. The results show differences between the values obtained , it shows that the preparation of the models found and used in the simulations were allocated amounts for different parameters that determine this difference in the estimate . Therefore, to rule, the models have difficulty understanding this because there is no clarity in the formulation of the equations , and the definition of variables and parameters would require a detailed study to...

Uma proposta de intervenção com atividade física individualizada na deficiência intelectual: um estudo de caso

The practice of regular physical activity has been considered a protective factor against the degenerative processes of the body, acting as a promoter of health, especially for risk groups such as obese and resistant groups exercise adherence as among the intellectually disabled (ID) . This study involved the administration of a training protocol and the physical parameters of longitudinal health in a subject about 43 years, intellectually deficient, hypertensive, obese and with a strong predisposition to develop diabetes and heart disease. The main objective of long-term program was to reduce body weight and normalize blood pressure (BP) after the student's physical activity and preferentially interfere with BP values at rest (ie before the daily schedule). The other objective was to improve general physical fitness. The protocol involved four meetings per week lasting one hour, in addition to participation in the program PROEFA (twice a week with sessions of one hour each), totaling 57 sessions spread over five months. The evaluation protocol included in each session the following tests: blood pressure measurements and heart rate, and amount of physical activity recorded via pedometer. Tests applied before and after the training included: anthropometric assessment, agility test, flexibility test, test drive through vertical and horizontal jumps and endurance to the test bench. The mass (kg) and BMI corresponded to the initial values of 127.7 kg and 42.05 kg m-2, and 5 months after 113.2 kg and 37.48 kg m-2, respectively. The waist-hip ratio was close to 1 after the intervention and this value corresponded to 0.98. For the test of agility (shuttle run) was not found improvement in performance. To test the values of the horizontal jump in pre-test were 52 cm and 56 cm post-test, vertical jump has been improved and...(Complete abstract click electronic access below)

A abordagem do voseo em materiais didáticos brasileiros de ensino do espanhol como língua estrangeira

This work discusses the importance of the language varieties in the Spanish language to the process of teaching and learning Spanish as a foreign language (ELE), focusing on the approach, ie, how to deal with the phenomenon voseo in Brazilian textbooks. It presents a brief historical overview on the arising of this language and its implementation in Latin America. From an educational approach that values a good development of communicative competence, it’s driven to a presentation of the Spanish schoolbooks selected by PNLD for the year 2012, as well as an observation of activities that demonstrate the phenomenon called voseo, in other words, the use of the variety of the pronoun vos instead of tú for the treatment of the second person. Given the vast range of Spanish courses as a foreign language for high school students, and the growing interest of young people in learning a second language, this study addresses the importance of developing the communicative competence of a foreign language

Efeito do pacing e do exercício prévio na performance aeróbia

The aim of this study was to analyze the influence of prior exercise on different intensity distribution strategies (pacing). The study included five male individuals, apparently healthy, aged between 18 and 25 years, and without regular practice of physical activities. The subjects were tested on different days following the protocols on a cycle ergometer: 1) a progressive ramp test, 2) three constant load tests in the intensities of 85%, 90% and 95% IVO2max to exhaustion, and 3) six tests with and without holding a prior exercise intensity of 70%  with different strategies for Even-intensity pace, ES (401 ± 70 W), which consists of an exercise at a pace and / or constant intensity from beginning to end; where intensity is initially increased to 10% less than the ES progressively increase to reach 10% above the intensity of ES, and; Fast-start; FS, where there is a reversal in the way of distributing intensity, ie the initial intensity is 10% higher than the value of ES decreased progressively to 10% below that ES. All these tests were performed in random order. The tlim with previous exercise was significantly shorter than without previous exercise at FS condition (p < 0.05). The VO2final obtained at ES condition was similar with (3243 ± 599 ml.min-1) and without (3252 ± 384 ml.min-1) previous aerobic exercise (p > 0.05). However, the VO2final obtained at FS condition was higher with (3291 ± 218 ml.min-1) than without (3097 ± 207 ml.min-1) previous aerobic exercise (p < 0.05). The heart rate was higher at ES condition with than without previous aerobic exercise (p < 0.05). There was no significant difference in this variable for FS condition with and without previous aerobic exercise (p > 0.05). It can be concluded that the results the previous exercise (70%) achieved lasting 6 minutes followed by 6 minutes of recovery appears to influence / commit ting the conditions during the pacing for this population
