introduction: standard semen analysis is routinly used to evaluate the male fertility, however some researchers belive that sperm functional test should also be used with standard semen analysis for more precise evaluation of male fertility. the aim of this study was to consider the relation between different nuclear maturity tests and in vitro fertilization, in order to select the nuclear matu...

Nuclear spectroscopy techniques are used to determine the elemental composition of planetary surfaces and atmospheres. Radiation, including gamma rays and neutrons, is produced steadily by cosmic ray bombardment of the surfaces and atmospheres of planetary bodies and by the decay of radionuclides within the solid surface. The leakage flux of gamma rays and neutrons contains information about th...

BACKGROUND Chemical, biological, radiological and nuclear terrorism poses considerable threat throughout the world. AIM To provide occupational physicians with an understanding of this threat and its main forms and what action can be taken to counter this threat. METHODS Presenters at a conference on chemical, biological, radiological and nuclear terrorism were asked to contribute their evi...

Nuclei prepared from MOPC-21 cells were treated with the nonionic detergents Triton X-100 or Nonidet P-40. Chemical analysis revealed that nearly 90% of the nuclear phospholipid was removed by detergent treatment. The membrane-denuded nuclei remained intact with preservation of nuclear pore complexes as demonstrated by electron microscopy. Ribonucleic acid transport from detergent-treated nucle...

Realistic surrogate nuclear debris is needed within the nuclear forensics community to test and validate post-detonation analysis techniques. Here we outline a novel process for producing bulk surface debris using a high temperature furnace. The material developed in this study is physically and chemically similar to trinitite (the melt glass produced by the first nuclear test). This synthetic ...

in this paper, we have tried to find a solution for quick transfer of nuclear wastes from pools of cool water to dry stores to reduce the environmental concerns and financial cost of burying atomic waste. therefore, the rate of heat transfer from atomic waste materials to the outer surface of the container should be increased. this can be achieved by covering the bottom of the pool space with c...

selecting within local pomegranate accessions is the main method used to identify new cultivars. total of 76 pomegranate accessions from hatay, turkey, were collected and their morpho-pomological and chemical characteristics were determined. the results showed that there was significant diversity among the accessions in terms of fruit quality parameters. several accessions were notable for thei...

The technetium-99m complex of the L,L-ethylenedicysteine diethylester (EC), of the brain imaging agent, was reported as a good choice for replacement of the renal nuclear medicines like OIH radiopharmaceutical. This present research work studies the structural, electronic and spectral properties of the EC compound and its complex with technetium-99m radionuclide from theoretical insight. All co...

Background: Breast cancer is known as the most widely recognized dangerous tumors; therefore, the most common reason for mortality among all instances of harmful neoplastic illness in females. This is because the lack of specific signs and symptoms at the early stage and at the aggressive nature. Currently, breast cancer treatment such as chemotherapy, surgery and radiotherapy has not been effe...

We study kinetic model of Nuclear Receptor Binding to Promoter Regions. This model is written as a system of ordinary differential equations. Model reduction techniques have been used to simplify chemical kinetics. In this case study, the technique of Pseudo-first order approximation is applied to simplify the reaction rates. CellDesigner has been used to draw the structures of chemical reactio...
