−Purified terephthalic acid (PTA) is critical to the development of the polyester industry. PTA production consists of p-xylene oxidation reaction and crude terephthalic acid (CTA) hydropurification. The hydropurification process is necessary to eliminate 4-carboxybenzaldehyde (4-CBA), which is a harmful byproduct of the oxidation reaction process. Based on the dynamic model of the hydropurific...
Cancer/testis antigens (CTAs) are a kind of antigens that their expression mostly is restricted in testis and female’s genital organs. Tumor cells often express antigens whose expression is normally limited to germ cells. CTAs are composed of a vast gene family of closely related members and are commonly classified into two groups: the CT-X antigens that are encoded by the X chromosome and the ...
BACKGROUND Primary to validate a commercial semi-automated computed tomography angiography (CTA) -software for vulnerable plaque detection compared to histology of carotid endarterectomy (CEA) specimens and secondary validating calcifications scores by in vivo CTA with ex vivo non-contrast enhanced computed tomography (NCCT). METHODS From January 2014 to October 2016 53 patients were included...
زمینه و هدف: ماهیت کار در اتاق های کنترل به گونه ای است که جزء کارهای پیچیده و با بار شناختی بالا تلقی شده و پیشگیری از وقوع خطاهای انسانی در این مشاغل ضروری به نظر می رسد. تحلیل شناختی وظایف اولین و مهمترین اقدام در جهت طراحی برنامه های پیشگرانه بوده و این مطالعه با هدف تعیین نیازهای شناختی وظایف، کمی سازی آنها و مقایسه سطوح نیازمندی های شناختی در گروه های شغلی در اتاق های کنترل یک صنعت پتروشی...
The melting of zigzag, armchair and chiral single walled boron nitride nanotubes (SWBNs) investigated using molecular dynamics (MD) simulation based on Tersoff-like many body potential. The MD simulation has been employed in the constant pressure, constant temperature (NPT) ensemble. The temperature and pressure of the system were controlled by Nose-Hoover thermostat and Berendsen barostat, res...
In this research, turbulent MHD convection of liquid metal with constant and variable properties is investigated numerically. The finite volume method is applied to model the fluid flow and natural convection heat transfer in a square cavity. The fluid flow and heat transfer were simulated and compared for two cases constant and variable properties. It is observed that for the case variable pro...
