zno and zno:mn nanocrystals synthesized via reverse micelle method. the size, band gap, urbach energy, optical constants and penetration depth of nanocrystals were calculated by uv-vis spectroscopy data. the surface morphology was studied with the use of scanning electron microscope (sem). moreover the samples exposed to gama ray source of 60co and their thermoluminescence properties were also ...
Abstract. A model of the radionuclide accumulation in fish taking into account contribution different tissues and allometry is presented. The basic assumptions are as follows. (i) organism represented by several compartments which radionuclides homogeneously distributed. (ii) correspond to three groups organs or tissues: muscle, bones (kidney, liver, gonads, etc.) differing metabolic function. ...
Postoperative radiotherapy (PRT) is widely advocated for patients with squamous cell carcinomas of the head and neck that are considered to be at high risk of recurrence after surgical resection. The aims of this study were to evaluate the treatment outcomes of PRT for patients with laryngeal carcinoma and to identify the value of several prognostic factors. We reviewed the records of 256 patie...
Our institution delivers TBI using a modified Theratron 780 60Co unit. Due to limitations of our treatment planning system in calculating dose for this treatment, we have developed a fast Monte Carlo code to calculate dose distributions within the patient. The algorithm is written in C and uses voxel density information from CT images to calculate dose in heterogeneous media. To test the algori...
background: the specific antibody response against newcastle disease virus (ndv) in the blood serum of chickens hatched from eggs exposed to low dose gamma-radiation was studied. materials and methods: two groups of eggs of commercial meat chicken lines were irradiated with the dose of 0.30 gy 60co gamma-rays before incubation and on the 19th day of incubation, respectively. the same number of ...
The paper represents the results of testing effect neutron and gamma radiation radioactive 60Co on electrical filters. Neutron was chosen because its conductivity. analysis standard structure electric filter found that can affect value capacitance as most important component filter. presented are a contribution to wider research resistance elements for coordination insulation at low-voltage lev...
