In the above article [1] , inequality in (12) should be \begin{equation*} \text {gcd}(\delta _{1},\delta _{2},\ldots,\delta _{N},2\pi) < 2\pi /(K+1)\end{equation*} </di...
Aims—To investigate the relation between changes in splanchnic arterial haemodynamics and renal arterial haemodynamics in controls and patients with cirrhosis. Methods—Superior mesenteric artery pulsatility index (SMA-PI) and renal artery pulsatility index (R-PI) were measured using Doppler ultrasonography in 24 controls and 36 patients with cirrhosis. These measurements were repeated 30 minute...
We have demonstrated a triangular assembly driven by 12 charged hydrogen bonds and pi-pi interactions. This assembly is stable even in polar solvents because of its charged hydrogen-bond nature. Helical arrangement of the complex is confirmed by its crystal structure. A solution structure is assigned to the D(3) isomer corresponding to the solid-state structure by temperature-dependent (1)H NMR...
Forty-two, one-day-old specific pathogen-free (SPF) chickens were randomly divided into two groups. On 21st day of study, experimental group was infected intraocularly with 1×106 EID50 of H9N2 and intratracheally with 1× 1010 CFU of Ornithobacterium rhinotracheale (ORT). Control group was inoculated with sterile PBS intraocularly. The samples from various tissues were collected on days 2, 4, 6,...
The susceptibility of membrane lipids to peroxidation (peroxidation index [PI]) increases with the double bond content of fatty acids and is inversely correlated to longevity in mammals, birds, and bivalve molluscs. In molluscs, membrane polyunsaturated fatty acids content can be affected by temperature, nutrition, and the individual's age. In this study, we evaluated how these three parameters...

Listeria monocytogenes induces the suppurative gastritis in some mice strains. In this study, characteristics of the gastritis caused by L. monocytogenes infection in mice were examined with time course of infection. Mice were administered intragastrically with 1.8 x 10(8) CFU of L. monocytogenes. Each three mice were sacrificed by cervical dislocation at 1, 3, 5, 7, 10, 14, 17, 21, and 28 days...
In this study, silicon nitride (SiNx) thin films were deposited on polyimide (PI) substrates as barrier layers by a plasma enhanced chemical vapor deposition (PECVD) system. The gallium-doped zinc oxide (GZO) thin films were deposited on PI and SiNx/PI substrates at room temperature (RT), 100 and 200 °C by radio frequency (RF) magnetron sputtering. The thicknesses of the GZO and SiNx thin films...

مدلسازی پیلهایسوختی شده است. اما بسیاری از این روشها به طور عملی و آزمایشگاهی بررسی نشده است و هنوز کمبود مطالعات موشکافانه روی پارامترها و روابط مربوط به متغیرهای عملکرد مشاهده می شود. از سوی دیگر، تنها مدلها و روشهای کمی به طور مخصوص به طراحی کنترلکننده پرداختهاست. مدلی که در این جا استفاده شدهاست، یک مدل به منظور تسهیل شبیهسازی سیستم قدرت همراه با پیلسوختی است و تنها نیاز به چند متغیر ا...
