Effects of wiping copper-alloyed stainless steel surfaces with disinfectants to remove protein surface contaminants and re-establish their antibacterial activities were quantitatively studied. Disinfectants used were sodium hypochlorite aqueous solutions and ethyl alcohol aqueous solutions. Wiping with NaOCl aqueous solutions effectively removed protein surface contaminants. Ethyl alcohol aqueo...

AIM Identification of women with moderate alcohol abuse during pregnancy is difficult. We correlated self-reported alcohol consumption during pregnancy and patient characteristics with objective alcohol indicators measured in fetal meconium. METHODS A total of 557 women singleton births and available psychological tests, obstetric data and meconium samples were included in statistical analysi...

Vegetable oils and fats in comparison with diesel fuel have high viscosity, by transesterification method the viscosity of oil can be decreased. Transesterification of triglyceride with alcohol is one of the methods for production of biodiesel. In this study sunflower oil, methanol and ethanol, with molar ratio of (1:3, 1:4, 1:6, 1:8) and temperature (40, 50, 60 º C) were dependent parameters e...

Introduction m a n y a c c e p t e d chemical methods for blood alcohol involve the oxidation of alcohol after a separation step1’ 2 and the subsequent determination of the excess of oxidant. On the other hand, enzymatic procedures1-4 are based on the conversion of diphosphopyridine nucleotide (DPN) to its reduced form (DPNH), catalysed by alcohol dehydrogenase (ADH) in the presence of ethyl-al...

The '80 h Ethyl Glucuronide (EtG) test' has become an idiom of the alcohol testing community, a review of the literature shows this window of detection applies only to extreme cases. EtG testing is becoming more common as a method to test for alcohol consumption in individuals who have been ordered to abstain from alcohol consumption. We tested 19 subjects using commercially available EtG kits....

In this paper, we present results of dielectric and shear-mechanical studies for amine (2-ethyl-1-hexylamine) and thiol (2-ethyl-1-hexanethiol) derivatives of the monohydroxy alcohol, 2-ethyl-1-hexanol. The amine and thiol can form hydrogen bonds weaker in strength than those of the alcohol. The combination of dielectric and shear-mechanical data enables us to reveal the presence of a relaxatio...

Determination of relative volatilities flavour compounds in hydro-alcoholic solutions is usually performed by time-consuming and costly standard methods such as the Gillespie dynamic recirculation method. This study tested a quick easy method with simple distillation apparatus for measuring empirical volatilities. A total 17 representative apple pear brandies were selected investigated their al...

1.1 The direct determination of ethanol itself in hair is not possible due to its volatility and its potential absorption from external sources. Instead, the minor ethanol metabolites ethyl glucuronide (EtG) and/or fatty acid ethyl esters (FAEEs) can be measured in hair as direct markers of alcohol consumption. 1.2 In this consensus FAEEs are defined as: ethyl myristate, ethyl palmitate, ethyl ...
