The use of a computer-controlled wedge system is an important segment of radiotherapy and increases the uniformity of dose in the target volume. The aim of this study is to verify the virtual wedge angles from the machine setup angles in Siemens’ ONCOR Linear accelerator (Linac) and compare it with published data of different linear accelerators as a function of beam energy and field sizes. This experiment was carried out on Siemens’ ONCOR impression linear accelerator. The doses at different depths were measured by using the CC13 ion chamber. During our work, the source to surface distance was kept 100 cm. The square field sizes on which we worked were 10, 15, and 20 cm<sup>2</sup>. The selected virtual wedge angles for our study are 15, 30, 45, and 60 degrees. This work was carried out for both photon energies 15 MV and 6 MV, tissue-equivalent water phantom IBA blue water phantom inside which all the observations were taken. The LDA99 detector for the virtual wedge profile was used. The wedge angle was calculated for the Siemen’s given formula. The variation in wedge angle from machine setup angle and published data as a function of beam energy and field sizes were analyzed. The variations increase with field size and wedge angle but decrease with beam energy. Variation is under 3% which is acceptable before treatment planning.</p> Nasir Ilyas, Salman Farrukh Copyright (c) 2020 Advanced Journal of Science and Engineering https://creativecommons.org/licenses/by-nc/4.0 http://www.ajscieng.com/index.php/ajse/article/view/ajse2014113 Thu, 22 Oct 2020 00:00:00 +0330 Heat Driven Spin Currents in DNA Chains http://www.ajscieng.com/index.php/ajse/article/view/ajse2014118 <p>Recent discoveries of phenomena involving the interaction of heat currents and spin currents have originated a vigorous field of spintronics, known as spincaloritronics. Meanwhile, creating the spin current via the applying the temperature gradient attracts much attention among the scientists. By using spin polarization, the spintronic phenomenon able to store and process the information, so transporting information is interested. On the other hand, widely known for storage of genetic information in biology, DNA has also been recognized as a useful building material, in the field of nanotechnology. Here, we study the spin-selectivity properties of DNA chains by assuming the Peyrard-Bishop-Holstein model. The temperature gradient applied using the temperature difference between two ends of chain via the Nose-Hoover thermostat. We suppose the generation of net spin currents by heat driving. The effect of external magnetic and electrical fields simultaneously with temperature gradient is studied. The obtained results show the appropriate range of affected factors for creating the spin current. Thus, one can design a most efficient device for spin transport.</p> Sohrab Behnia, Fatemeh Nemati, Samira Fathizadeh, Mostafa Salimi Copyright (c) 2020 Advanced Journal of Science and Engineering https://creativecommons.org/licenses/by-nc/4.0 http://www.ajscieng.com/index.php/ajse/article/view/ajse2014118 Thu, 22 Oct 2020 00:00:00 +0330 A Review on Eco-Friendly Synthesis of BiVO4 Nanoparticle and its Eclectic Applications http://www.ajscieng.com/index.php/ajse/article/view/ajse2014106 <p>The paper presents a review of green syntheses and selective applications of bismuth vanadate nanoparticles (BiVO<sub>4</sub> NPs). Generally, ample number of biomolecules exists in plant extracts and these are mainly accountable for the facile green synthesis of BiVO<sub>4</sub> NPs. Moreover, BiVO<sub>4</sub> NPs has been widely researched in chemistry, biotechnology, physics and biochemistry fields due to their interesting technological chemical, biological, ionic conductivity and ferro-elastic properties. It can also be used in diverse fields, such as sensors, photocatalysis, water splitting and antimicrobial activity. Till date, BiVO<sub>4</sub> NPs has been synthesized by various known physical and chemical approaches. The article mainly discusses the green synthesis of BiVO<sub>4</sub> NPs via plant extracts. Moreover, this article shows a detailed overview of the green synthesis, characterization and significant applications of BiVO<sub>4</sub> NPs.</p> Suresh Ghotekar, Khanderao Pagar, Shreyas Pansambal, H.C.
