Background: Increasing the complexity in modern radiotherapy techniques have increased the delivery time lowering consequently the treatment efficacy. Through simulating the delivery time delay encountered in such techniques, its’ effect on two cancer cell lines and the compensating doses given to prevent such effect was investigated. Materials and Methods: F10B16 and 4T1 cancer cell line...
On the basis of the temperature range in which growth can occur, bacteria are usually divided into 3 groups, namely: thermophiles, mesophiles, and psychrophiles (sometimes called cryophiles or rhigophiles). Thermophiles have temperature optima (generally quite close to temperature maxima) 10 to 25 degrees above the temperature optima of mesophiles. Thermophiles and mesophiles are easily disting...
Internal polarizations field which take place in quantum structures of group-III nitrides have an important consequence on their optical properties. Optical properties of wurtzite AlGaN/GaN quantum well (QW) structures grown by MBE and MOCVD on c-plane sapphire substrates have been investigated by means of photoluminescence (PL) and time resolved photoluminescence (TRPL) at low-temperature. PL ...
deposite the different criticisms on contrastive analysis it has been proved that the results of it(when processed)can be usuful in a tefl environment,specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims. the consonants,vowels,stress and intonation of the twolanguages are described by the same model-ta...
Background and Objective: Studies have shown that estradiol and Portulaca oleracea extract have analgesic effects. The main aim of this study was to investigate the effect of co-administration of estradiol and Portulaca oleracea seed hydroalcoholic extract on pain induced by writhing test in female mice. Materials and Methods: In this experimental study, 78 female balb c mice were randomly d...

Silicon carbide (SiC) semiconductor is an ideal material for solid-state nuclear radiation detectors to be used in high-temperature, high-radiation environments. Such harsh environments are typically encountered reactor measurement locations as well high-level radioactive waste and/or “hot” dismantlingdecommissioning operations. In the present fleet of commercial reactors, temperatures excess 3...
Increasing nitrogen absorption efficiency reduces use of excessive application of N. The effect of rootzone temperature on nitrogen absorption needs clarification. The experiment was conducted to investigate low (15°C, RTZ1), high (35°C, RTZ2) and optimum (25°C, RTZ3) root zone temperatures and nitrogen 52.5 (ND1), 78.75 (ND2) and 105 (ND0) mg∙L-1 levels on cucumber (Cucumis sativus L.), cv. Su...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
