Depleted uranium (DU), a waste product of uranium enrichment, has several civilian and military applications. It was used as armor-piercing ammunition in international military conflicts and was claimed to contribute to health problems, known as the Gulf War Syndrome and recently as the Balkan Syndrome. This led to renewed efforts to assess the environmental consequences and the health impact o...

Nuclear fuel cycle workers are exposed to a variety of hazardous materials. Uranium processing is one of the stages of the nuclear fuel cycle and, together with uranium underground mining, employs the largest number of workers, with much smaller groups of workers involved in uranium enrichment and reprocessing and reactor operation. To date, epidemiological studies of uranium underground miners...

Syntheses of the bimetallic uranium(III) and neptunium(III) complexes [(UI)(2)(L)], [(NpI)(2)(L)], and [{U(BH(4))}(2)(L)] of the Schiff-base pyrrole macrocycles L are described. In the absence of single-crystal structural data, fitting of the variable-temperature solid-state magnetic data allows the prediction of polymeric structures for these compounds in the solid state.

The application of hypofluorites (fluoroxy-compounds), especially tnfluoromethyl hypofluorite, in the synthesis of fluorinated steroids is described. Hypofluorites are powerful but selective fluorinating agents with unusual electrophilic character. They should find considerable application not only in the synthesis of fluorinated steroids, but for preparation of fluorinated compounds of many di...

abstract uranium is a radioactive heavy metal. development of nuclear industries and application of phosphate fertilizers contain uranium impurity resulted in soil contamination with uranium. a pot experiment had been conducted under controlled condition. the experiment carried out in completely randomized design with two factors, including two plants (soybean and sunflower) and six levels of u...

Uranium is one of the most studied actinoids, widely used in nuclear industry, and can accumulate drinking water, soil, plants, calcium-containing body tissues. The purpose work was to investigate presence uranium isotopes U-235 U-238 composition kidney stones patients with urolithiasis living Kharkiv region. content investigated samples obtained as a result minimally invasive surgical interven...

The linear perturbation group transformation (LPRG) is used to study the thermodynamics of the axial nextnearest-neighbor Ising model with four spin interactions (extended ANNNI) in a field. The LPRG for weakly interacting Ising chains is presented. The method is used to study finite field para-ferrimagnetic phase transitions observed in layered uranium compounds, UAs1−xSex , UPd2Si2 or UNi2Si2...

Depleted uranium (DU) is a radioactive heavy metal coming from the nuclear industry and used in numerous military applications. Uranium inhalation can lead to the development of fibrosis and neoplasia in the lungs. As little is known concerning the molecular processes leading to these pathological effects, some of the events in terms of genotoxicity and inflammation were investigated in rats ex...

To produce nuclear fuels, it is necessary to convert uranium′s ore into UO2-ceramic grade, using several quantities of kerosene, methanol, nitric acid, ammonia, and, in low level, tributyl phosphate (TBP). Thus, the effluent generated by industries one most toxic since contains high concentrations dangerous compounds. This paper explores biological parameters on real wastewater Monod model an O...

Uranium contamination is a worldwide problem. Preventing uranium contamination in the environment is quite challenging and requires a thorough understanding of the microbiological, ecological and biogeochemical features of the contaminated sites. Bioremediation of uranium is largely dependent on reducing its bioavailability in the environment. In situ bioremediation of uranium by microbial proc...
