In glassy isopentane at 77 K, 1-phenyl-4-(4-pyridyl)-cis-1,cis-3-butadiene (cc-PPyB) and 1-phenyl-4-(4-pyridyl)-cis-1,trans-3-butadiene (ct-PPyB) can undergo simultaneous two-bond photoisomerization. Under the same conditions, 1-phenyl-4-(4-pyridyl)-trans-1,cis-3-butadiene (tc-PPyB) gives tt-PPyB, the ultimate photoproduct in all cases.
We present an analytic method to efficiently calculate the torque constant and cogging torque of a hybrid stepping motor. The feature of the proposed method is its computational efficiency in that it is a useful tool for the motor design which is aimed at reducing the level of cogging torque or increasing the torque constant. This method is verified by comparing with the 3D finite element metho...
BACKGROUND Lower extremity torque steadiness has been shown to be an independent predictor of functional performance in older women. Hip muscle function is crucial for many types of activities of daily living, yet existing studies investigating torque steadiness for lower extremities are limited to assessing steadiness at the knee and ankle. OBJECTIVE The purpose of this study was to compare ...
For the past century, public health officials have relied on fecal coliforms to identify and track bacterial contamination. However, several issues arise when using coliforms as indicators for viral pathogen risk. First, there is a lack of association between fecal coliforms and human enteric viruses in the environment. Second, there are differences in the fate of coliforms compared to viral pa...
چکید ه سابقه و هدف TTV برای نخستین بار در سال 1997 در خون بیماران ژاپنی با سطوح بالای آلانین ترانسفراز( ALT ) که عاری از دیگر ویروس‌های عامل هپاتیت بودند، کشف شد. به منظور تعیین فراوانی آلودگی به TTV و نقش آن در آسیب‌های کبدی، نمونه‌های سرمی افراد به ظاهر سالم و افراد آلوده به ویروس‌های HBV و HCV از سازمان انتقال خون شهر تبریز تهیه گردید و مورد آزمایش قرار گرفت. مواد وروش‌ها مطالعه ان...
We conducted an unbiased metagenomics survey using plasma from patients with chronic hepatitis B, chronic hepatitis C, autoimmune hepatitis (AIH), non-alcoholic steatohepatitis (NASH), and patients without liver disease (control). RNA and DNA libraries were sequenced from plasma filtrates enriched in viral particles to catalog virus populations. Hepatitis viruses were readily detected at high c...
Cardiovascular diseases (CVDs) are the leading cause of death worldwide. An expanding body of evidence supports the role of human microbiome in the establishment of CVDs and, this has gained much attention recently. This work was aimed to study the circulating human microbiome in CVD patients and healthy subjects. The levels of circulating cell free DNA (circDNA) was higher in CVD patients (n =...
