Total mercury (T-Hg) was determined in fish and wild animal meat consumed indigenous villages the Brazilian Amazon region, where there is no history of gold mining. The analyses were performed an atomic absorption spectrophotometer by generation cold vapour. Regardless dietary habit, 42.0% had levels T-Hg higher than values considered as safe for human health World Health Organisation. Exposure to due consumption compared animals. Carnivorous species showed a concentration T-Hg, both It...
The length-biased Birnbaum-Saunders distribution is both useful and practical for environmental sciences. In this paper, we initially derive some new properties the distribution, showing that one of its parameters mode it bimodal. We then introduce a regression model based on distribution. implement maximum likelihood method parameter estimation, approach interval estimation consider three types residuals. An elaborate Monte Carlo study carried out evaluating performance likelihood-based...
The data of water consumption a city is prerequisite for planning and management resources, since it provides the drafting basic sanitation.This work aims to calculate per capita treated domestic use in Ariquemes-RO.It has been found that 58.6 % households have monthly average during year maximum 15 cubic meters.The Estimativa do consumo de água tratada para uso doméstico por meio ferramentas estatísticas: estudo caso da cidade Ariquemes (RO)
RESUMO : De acordo com a Agencia Nacional de Vigilância Sanitaria- ANVISA, inumeras patologias estao associadas aos procedimentos manicure/pedicuro, comprometendo assim saude da populacao que procura por esses servicos e tambem do proprio profissional. Neste contexto, realizou-se uma pesquisa caracteristica participativa, atraves aplicacao de questionarios profissionais trabalham em saloes beleza municipio Ji-Parana, o objetivo conhecer avaliar os biosseguranca utilizados durante rotina...
Stochastic production frontier models are widely used in microeconometrics and, the last decades, have been proven to be versatile their range of applications. However, there few studies concerning endogeneity stochastic models. Here we present two with endogenous variables based on main distributions for technical inefficiency. We also derive analytic gradient vectors obtain best performance at a reasonable computational time cost. The methodology presented here is one and two-step maximum...
The global climate is dependent of ecological balance forests, especially tropical. heat flux in the soil an important factor studies energy representing main form exchange between and atmosphere. aim present work was to estimate using temperature measurements at two depth levels a tropical forest Western Amazon, order obtain coherent data for both use values filling failures database. Had been used on collected micrometeorological tower belonging towers network Large Scale...
