Vanek’s tumor is a rare benign inflammatory fibroid polyp like localized lesions originating in the submucosa of the gastrointestinal tract. Intussusceptions due to inflammatory fibroid polyps are uncommon; moreover, ileo-ileal Intussusception presenting as subacute small bowel obstruction has rarely been reported. We report a 49-year-old man who came with complaints of indigestion, flatulence,...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
Systems Development:-Basic flaws in the current culture-Ideas for rectifying some of the problems It is nov 21 years since the term 'Software Engineering' vas coined. In this time relatively little progress seems to have been made in getting the development of computing systems under control. This paper identifies three basic flavs in computing systems development cUlture, it tries to identify ...
Faster and more accurate ranging can be achieved by combining the object detection technique based on deep learning with conventional visual ranging. However, changes in scene, uneven lighting, fuzzy boundaries other factors may result a non-fit phenomenon between bounding box object. The pixel spacing cause errors. To reduce spacing, increase degree of fit object, improve accuracy, an optimiza...
پنل های خورشییدی دارای مشیه ه جریان -ولتاژ غیر خطی بوده و تنها در یک نقطه کار خاص، حداکثر توان را تولید می کنند. این نقطه بهینه توان با تغییر دما و شیدت نور تغییر می کند. روش های مهتلفی برای ردیابی نقطه حداکثر توان به صورت free model و based model معرفی شده است. این تحقیق روش جدیدی جهت بهبود عملکرد ردیابی نقطه حداکثر توان پنل های خورشیدی جدا از شبکه ارائه می دهد و الگوریتم روش پیشینهادی از دو...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
G2A (from G2 accumulation) is a G-protein-coupled receptor (GPCR) that regulates the cell cycle, proliferation, oncogenesis, and immunity. G2A shares significant homology with three GPCRs including ovarian cancer GPCR (OGR1/GPR68), GPR4, and T cell death-associated gene 8 (TDAG8). Lysophosphatidylcholine (LPC) and sphingosylphosphorylcholine (SPC) were reported as ligands for G2A and GPR4 and f...
Keywords: Time reliability GPS Route choice Random utility I-394 HOT MnPass Mixed logit Bootstrap a b s t r a c t In the Minneapolis–St. Paul region (Twin Cities), the Minnesota Department of Transportation (MnDOT) converted the Interstate 394 High Occupancy Vehicle (HOV) lanes to High Occupancy Toll (HOT) lanes (or MnPASS Express Lanes). These lanes allow single occupancy vehicles (SOVs) to ac...
