Workflow technologies have become a major vehicle for easy and efficient development of scientific applications. A critical challenge in integrating workflow technologies with state-of-the-art resource provisioning technologies is to determine the right amount of resources required for the execution of workflows. This paper introduces an approximation algorithm named BTS (Balanced Time Scheduli...
Unique physicochemical properties of carbon nanomaterials (CNMs) have opened a new era for therapeutics and diagnosis (known as theranostics) of various diseases. This exponential increase in application makes them important for toxicology studies. The present study was aimed at exploring the toxic potential of one of the CNMs, that is, bucky tubes (BTs), in human lung adenocarcinoma (A549) cel...
As demand for wireless broadband grows, so does the importance of cellular base station (BTS) performance. The low noise amplifier (LNA) on the antenna tower is a key element in establishing BTS performance, affecting both the base station’s area of coverage and its tolerance of other nearby transmitters. Integrated LNAs with active bias regulators, such as Avago Technology’s MGA-63x family, pr...
با توجه به رشد سریع تکنولوژی تلفن همراه جهت افزایش تعداد متقاضیان این تکنولوژی ، لازم است که باند فرکانس این سیستم از 900 mhz به 1800 mhz انتقال یابد. استفاده از روش های دایورسیتی جهت بهبود کیفیت سیگنال دریافتی الزامی خواهد بود. صرفنظر از تکنیک های مختلفی دایورسیتی ، دریافت دو سیگنال مختلف توسط آنتن بخشی از این روش می باشد. استفاده از دو آنتن مجزا که در صفحه افقی در فاصله متناسب از یکدیگر قرار ...
این مقاله به امکانسنجی استفاده از واحد فتوولتائیک در صنعت مخابرات برای تأمین برق مصرفی BTSها میپردازد.شرکت مخابرات برای افزایش دامنه پوشش تلفن همراه نیازمند نصب BTS در مناطق مختلف است و تأمین برق مصرفی BTS، در مناطق دور از شبکه برق از مشکلات پیش رو در توسعه شبکه مخابراتی است. دراین مقاله ابتدا راههای تأمین انرژی مورد نیاز BTS معرفی شده، سپس اقلیم آب و هوایی یک منطقه خاص در نظر گرفته شده و ب...
BACKGROUND Canine epileptoid cramping syndrome (CECS) is a paroxysmal movement disorder of Border Terriers (BTs). These dogs might respond to a gluten-free diet. OBJECTIVES The objective of this study was to examine the clinical and serological effect of a gluten-free diet in BTs with CECS. ANIMALS Six client-owned BTs with clinically confirmed CECS. METHODS Dogs were prospectively recrui...
Because the major processes involved in muscle contraction require rapid utilization of ATP, measurement of ATP utilization can provide important insights into the mechanisms of contraction. It is necessary, however, to differentiate between the contribution made by cross-bridges and that of the sarcoplasmic reticulum (SR) Ca2+ pumps. Specific and potent SR Ca2+ pump blockers have been used in ...
Results from the Bac-T-Screen (BTS) of fresh urine specimens were compared with the BTS results obtained when the same urine specimens had been held at room temperature for 24 h. Of the 246 specimens studied, 43 were initially BTS positive, 11 were false-negative, and 39 had greater than or equal to 10(5) CFU/ml. After 24 h at room temperature an additional 60 specimens had greater than or equa...
