In a series of communications (1) we have reported experiments which show that antirachitic properties can be imparted to various inert fluids by means of ultra-violet irradiations. In the first report, presented in June, it was recorded that this held true for vegetable oils, such as cottonseed oil. Subsequent to irradiation 0.1 cc. of this oil was sufficient to protect young rats which had be...

several common approaches are used for disinfection of water in this section, but using the approaches (e.g. chlorination) are accompanied with hazardous by-products and also lead to notable changes in odor and flavor of water. gamma irradiation as an emerging method has been encouraged currently by fao/who for water, wastewater and food treatment. coliform bacteria belong to common contaminant...

The aim is to develop irradiated nanodiamonds (INDs) as a molecularly targeted contrast agent for high-resolution and phenotype-specific detection of breast cancer with photoacoustic (PA) imaging. The surface of acid treated radiation-damaged nanodiamonds was grafted with PEG to improve its stability and circulation time in blood, followed by conjugation to an anti-HER2 peptide with a final nan...

Abstract In this paper, we present the results of inter-comparison studies on identification irradiated food carried out by leading European laboratories from 1991 to 2018. 1990s, Federal Institute for Health Protection Consumers and Veterinary Medicine in Germany played role organization inter-laboratory tests subject. At beginning century, Spanish Agency Food Safety Nutrition National Centre ...

[1] We have studied the effects of 4 keV He ion irradiation on olivine while measuring, in situ, changes in the near-infrared (NIR) reflectance and in the chemical composition of the surface. The observed changes in reflectance are reddening and the attenuation of the Fe-3d absorption bands in the NIR. Spectral reddening of irradiated olivine powder (<45 mm) correlates with the amount of metall...

The trade and acceptance of foods treated with ionizing radiation, gamma radiation or x-rays, require appropriate means of control. A foolproof test to detect whether or not food has been irradiated, and eventually to quantify the amount of radiation, is vital to verify the labelling and enforce legislation. Such an assay also provides the information for avoiding repeated irradiations which ar...

volatile compounds generated from two types of polymeric laminated films, irradiated by gamma radiation at 8, 10 and 15 kgy, were investigated. activated carbon was used as a dry food simulant to trace the migrating compounds by gas chromatography/mass spectroscopy (gc/ms). the resulting data showed that the polyethylene terephthalate (pet)/polyethylene terephthalate (pet)/linear low density po...

Chlorpyrifos is an organophosphate insecticide, used to control foliage and soil-borne insect pests on a variety of food and feed crops. In the natural environment, Chlorpyrifos can be degraded  through  several  possible  processes,  including  photodegradation, biodegradation,  and hydrolysis.  In  the  present  work  the  photodegradation  and  environmental  fate  of  Chlorpyrifos  in aqueo...

Although the United States food supply is generally considered one of the safest in the world, foodborne illnesses remain a concern. Each year, millions of Americans become ill and as many as 5000 die from foodborne infections. The United States Department of Agriculture estimates that medical treatment and productivity losses associated with foodborne illnesses cost as much as $37 billion annu...
