This review article describes the ultrasonographic findings of the liver, spleen, urinary tract and greater omentum that were previously obtained in studies of healthy female Saanen goats. Real-time B-mode ultrasonography and a linear or convex 5.0 to 7.5 MHz transducer are used to scan standing goats from both sides. The urinary bladder and urethra are also examined transrectally. The liver is...
شکست کاتالیستی سیال (fcc)، فرایندی برای تبدیل برش های سنگین نفت به محصولات با ارزش می باشد. در تحقیق حاضر، شبیه سازی cfd هیدرودینامیک و انتقال حرارت راکتور استوانه ای بالارونده سه فازی (گاز- مایع- جامد) فرایند fcc با در نظر گرفتن تبخیر قطرات مایع انجام شده است. به دلیل عدم تقارن ورودی، بخار، ذرات کاتالیست و قطرات خوراک اتمایز شده به صورت سه بعدی مدل سازی شده است. برای مدل سازی فاز گاز و ذرات کا...
in this paper, we have examined abrupt changes in volatility of tepix index in tehran stock exchange during august 23, 2010 to june 12, 2014. applying the iterated cumulative sum of squares (icss) algorithm proposed by inclan and tiao (1994) and the modified version of this algorithm consisting kappa 1 and kappa 2 test statistics developed by sansó et al. (2004), we have specified that the dete...
Over the past decade, cyber security community has witnessed a trend in which advanced adversaries – such as nation-state actors and cybercriminal groups are increasingly shifting their exploitation efforts from IT systems to OT Industrial Control Systems (ICSs). This stems fact that compromise of an ICS can have far greater consequences than traditional system potentially resulting not only fi...
BACKGROUND The International Carotid Stenting Study (ICSS) of stenting and endarterectomy for symptomatic carotid stenosis found a higher incidence of stroke within 30 days of stenting compared with endarterectomy. We aimed to compare the rate of ischaemic brain injury detectable on MRI between the two groups. METHODS Patients with recently symptomatic carotid artery stenosis enrolled in ICSS...
Over 100 years ago, George Bernard Shaw, speaking through his protagonists, weapons manufacturer Andrew Undershaft and Undershaft’s daughter Salvation Army Major Barbara, explored the uneasy relationship that existed, and exists still, between ill-gotten gains and the public good. Now, a century later, a similar uneasy relationship exists. But this time it is not cannons versus religion, but to...
Information and communication systems (ICSs) must comply with increasingly stringent requirements to ensure the reliability speed of information transmission, noise immunity, security. This paper reports methods synthesize discrete complex cryptographic signals, underlying construction which are random (pseudo-random) processes; for synthesizing characteristic signals whose is based on using na...
COPD is projected to be the third-leading cause of death by the year 2020. Pharmacotherapy for COPD is palliative at best, having no impact on slowing the progression of the disease. The introduction of newer therapies such as long-acting forms of bronchodilator and anticholinergic agents, together with the inclusion of inhaled corticosteroids (ICSs) in the recent Global Initiative for COPD the...
OBJECTIVE Inadequate asthma control may affect asthma resource use and treatment charges, consequently contributing to the growing economic burden of asthma. The study objective was to determine the impact of medication adherence and asthma control on resource use and charges in mild asthmatic patients treated with inhaled corticosteroids (ICSs). RESEARCH DESIGN AND METHODS A claims database ...
Asthma management guidelines emphasize the importance of effective treatment to achieve and maintain control of asthma. However, despite widely available and effective treatments, achieving control of asthma is still an unmet need for many patients. Adding a second bronchodilator with a different mechanism of action for the treatment of uncontrolled asthma can be a suitable therapeutic approach...
