There is accumulating evidence determine that the metabolism of some trace elements is altered in diabetes mellitus (DM) type II. The current study aimed to evaluate the effect of serum blood glucose fluctuation during (Random, Fasting and Postprandial 2hours state) on some trace elements such as Cadmium (Cd), Chromium (Cr), Manganese (Mn), Magnesium (Mg), Zinc (Zn), Copper (Cu), Sodium (Na), P...
This paper focuses on the development of capacitor voltage balancing methods in a flying capacitor multilevel inverter (FCMLI) fed induction motor drive. For improve the performance of flying capacitor multilevel inverter to implement a switching pattern selection scheme. This reduces capacitor voltage fluctuation without using voltage feedback and RLC Filter circuits connected in parallel with...
Poly(A)-containing mRNA was isolated from division synchronized populations of the ciliated protozoan, Tetrahymena pyriformis. The level of tubulin and actin mRNA at specific cell cycle stages was analyzed by hybridization to tubulin and actin cDNA probes and by gel analysis of their in vitro translation products. The pattern of fluctuation of tubulin mRNA levels was similar to that observed fo...
To evaluate the level of stress induced by clinical training, ambulatory electrocardiograms from 12 healthy female medical technology students were recorded and the spectral components of heart rate variability (HRV) were analyzed as an index of autonomic nervous function. The HF power reflecting parasympathetic tone was significantly decreased at awakening, compared with that before clinical t...
Functional magnetic resonance imaging (fMRI) has become a leading tool in the evaluation of the human brain function. In fMRI the activation induced blood oxygenation changes in the brain can be detected with an inherent blood oxygen level dependent (BOLD) contrast. Even small blood oxygen fluctuations in a resting brain can be depicted with the BOLD contrast. This thesis focuses on characteriz...
The authors propose specific temporal profiles that reflect certainty versus doubt about where a partner stands with respect to a dating relationship over time. Two multiwave longitudinal studies focused on within-participant changes in perceived partner commitment. Results from multilevel modeling indicate that individuals whose perceptions of partner commitment fluctuate over time were more l...
Short-interval water level measurements using automatic water level recorder in a deep well in an unconfined crystalline rock aquifer at the campus of NGRI, near Hyderabad shows a cyclic fluctuation in the water levels. The observed values clearly show the principal trend due to rainfall recharge. Spectral analysis was carried out to evaluate correlation of the cyclic fluctuation to the synthet...
A mutant strain of the green alga Chlamydomonas reinhardi, ac-20, is described in which both the rate of CO(2) fixation by whole cells and the rate of carboxylation of ribulose-1,5-diphosphate in cell-free extracts are reduced, particularly when sodium acetate is present in the growth medium. Of the enzymes of the reductive pentose phosphate cycle tested, only ribulose-1,5-diphosphate carboxyla...
هدف این مقاله، مطالعه رابطه بین اعلام میزان سهام شناور شرکتها با حجم معاملات، نوسانپذیری و بازده سهام شرکتهای پذیرفته شده در بورس اوراق بهادار تهران است. در این راستا، تعداد 188 شرکت پذیرفته شده در بورس اوراق بهادار تهران بررسی و جهت آزمون فرضیهها از دادههای تلفیقی با اثرات ثابت و نرم افزار Eviews 6 استفاده شده است. یافتههای تحقیق نشان میدهد که بین اعلام میزان سهام شناور شرکتها و حجم م...
