Os autores realizaram determinações da taxa de hemoglobin em cerca de 3.000 operários da Fábrica Nacional de Motores. Administrativamente os operários e técnicos da referida Fábrica, estão divididos em diversas categorias de acordo com o salários e a função exercida. Os resultados foram os seguintes: Dentre os resultados, os operários salário mínimo, médio e mensalistas (menos de Cr$ 600,00 mensais), são significativamente diferentes, comparados com a curva normal de hemoglobina (profissões liberais). Além disso, mostraram êsses grupamentos uma alta percentagem de indivíduos com ligeira anemia (hemoglobina abaixo de 10, 00 g) o que se traduz por um desvio padrão elevado. Verificamos finalmente que uma alimentação, constituída de rações perfeitamente balanceadas em calorias, vitaminas e sais minerais, controlada por nutricionista, pelo prazo de um ano, não elevou as taxas de hemoglobina.
Three thousands hemoglobin determinations have been made in the National Motor Plant workers. According to their salaries these workers could be classified in different categories. Correlation between hemoglobin levels and economic status have been studied. As compared to our own observation of hemoglobin levels in normal men of high standards of living the results found have been of a significative difference, as showed in following chart: Workers with low and medium salaries showed a appreciable percentage of individuals slightly anemic (Hemoglobin below 10.00 grs per 100 ml blood) reflected in a higher standard deviation of the curves constructed from these data. It has been verified that food controled by a nutritionist for a period of a year were not able to correct the blood picture in individuals in which the hemoglobin level were below normal
The rough grind machine operation in metallic material produce a sub product with the followings components such as: metallic residue, small parts come from the resin grinds, diatomaceous earth material (filter material) and soluble oil in water for tools cooling. According [H U 1U H ] from ABNT, this sub product is toxic, not inert material, aggress the environment with pollution in the currency water and contaminate the ground when incorrectly go to the municipal solid waste. The final destination of this sub product, is the incineration, in the cements company, being the incorporated the sub product to the cement, during your production.With the qualitative result using the scanning electron microscopy (SEM), coupled to the dispersive energy spectroscopy (EDS), two experiments were made with objective to separate the magnetic material of the non-magnetic material, using a permanent magnet. We conclude that the magnetic material can be used by powder metallurgy process in production of pieces.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
