The administration of cobalt to rats caused a marked increase in the oxidative degradation of heme (hematin, iron protoporphyrin-IX) BY HEPATIC MICROSOMAL ENZYMES. The onset of this enzyme stimulation was very rapid, beginning within 2 hours after injection of the metal and reaching its maximum in 16 to 24 hours. During the rapid phase of stimulation, i.e. the first 2 to 4 hours, when heme oxid...

BACKGROUND Although stress is known to be a common occupational health issue in the veterinary profession, few studies have investigated its broad domains or the internal validity of the survey instrument used for assessment. METHODS We analysed data from over 500 veterinarians in Queensland, Australia, who were surveyed during 2006-07. RESULTS The most common causes of stress were reported...

The increased production of coconut has by the shell produced, even though this lignin content 33.30% so it potential to be converted into charcoal through pyrolysis process. Pyrolysis is a thermal decomposition process that occurs without air or with little convert biomass charcoal. Coconut can used for coal co-firing in developing new and renewable energy. This study aimed obtain best tempera...

This paper investigates trends and changes in the structural composition of women’s weekly market hours in former West-Germany using aggregate time-series data from German micro census from 1957 until 2001. Aggregate weekly hours per working-age woman are decomposed into hours worked per employee – the intensive margin of adjustment – and into labor force participation – the extensive margin. T...

In its classic form, the objection is that backward time travel entails the occurrence of impossible things, such as auto-infanticide—and hence is itself impossible. David Lewis has rebutted the classic version of the objection: auto-infanticide is prevented by coincidences, such as time travellers sli...
