The Cover Feature shows that 1-butene molecules can penetrate into a dense crystalline solid and drive the transformation of planar trinuclear fluorinated copper(I) pyrazolate complexes toward boat-shaped, dinuclear copper-butene adducts. chemistry these with is also examined in solution, comparison analogous adducts formed ethene propene provided.

BACKGROUND Copper is essential as a trace element for metabolic processes. Exposure to copper in industries develops toxicity among the workers. Previous findings on adverse effects of copper on male reproductive function in adult albino rats led to investigate the effects of this metal on reproductive function of maturing male rats in the present experiment. METHODOLOGY To study these effect...

Holmberg and Laurell (1948) gave the name " caeruloplasmin " to a blue copper globulin complex which they had isolated from both pig and human blood (1947). It was obtained by ammonium sulphate precipitation and was found to be active as an oxidase against p-phenylenediamine. Tlhey considered it to be an a globulin with a molecular weight of about 150,000. Other workers (Scheinberg and Gitlin, ...

The search for a sensitive histochemical method for revealing tissue copper has been the object of many workers in the past. In spite of multiple methods available, the occurrence in clinical practice of negative histochemical stains, even in cases with high copper levels demonstrated by quantitative methods is very high.This study was aimed at verifying the role of technical variations in the ...

UNLABELLED BACKGROUND The metals bioavailability in soils is commonly assessed by chemical extractions; however a generally accepted method is not yet established. In this study, the effectiveness of Diffusive Gradients in Thin-films (DGT) technique and single extractions in the assessment of metals bioaccumulation in vegetables, and the influence of soil parameters on phytoavailability were...

BACKGROUND The nuclear weapons industry has long been known as a source of beryllium exposure. METHODS A total of 1,004 former workers from a nuclear weapons assembly site in the Midwest were screened for sensitization to beryllium (BeS). The screenings were part of the Department of Energy (DOE) Former Worker Program established in 1996. RESULTS Twenty-three (2.3%) workers were found sensi...

A group of 39 storage battery workers was evaluated in terms of pertinent biochemical parameters with regard to duration and degree of occupational exposure to lead. Twenty-two of the group had recognized toxic blood lead levels of greater than 60 mcg/100 ml, but fully 31 exceeded the Center for Disease Control's upper limit of normal for erythrocyte protoporphyrin. Other abnormal values found ...

conclusions general fatigue and its subscales had a significant relationship with workplace physical trauma among miners. workplace physical trauma can be reduced by managing fatigue with different programs, including decreasing the workload, scheduling rest breaks at the facilities, and possibly providing welfare and entertainment opportunities for the workers. background fatigue may lead to o...

There is dearth of researches pertaining to prevalence of mental morbidity in Industrial setups, particularly in our country.They are important as psychological ill health of workers may adversely effect the productivity in developing country like India.Khetri Copper Complex in Rajasthan was selected for present study. Aims were to determine the period prevalence of mental morbidity among worke...
