A thermostatted dynamical model with five degrees of freedom is used to test the fluctuation relation of Evans and Searles (Omega-FR) and that of Gallavotti and Cohen (Lambda-FR). In the absence of an external driving field, the model generates a time-independent ergodic equilibrium state with two conjugate pairs of Lyapunov exponents. Each conjugate pair sums to zero. The fluctuation relations...
Using the heterotopically transplanted rat urinary bladder, we have shown that normal rat urine has a potent tumor-enhancing effect on bladder carcinogenesis. In an attempt to isolate tumor-enhancing factor(s), urine was fractionated by Bio-Gel P-100 column chromatography and each eluate fraction was examined for inducibility of ornithine decarboxylase (ODC) in a target rat bladder carcinoma ce...
سابقه و هدف: یکی از ناهنجاری های شایع در بیماران ارتودنسی ناهنجاری cl ii/i است. برای اصلاح آن از انواع دستگاه های فانکشنال استفاده می گردد. بنابراین، با توجه به تناقضات موجود در مورد اثر دستگاه پلن شیبدار بر تغییرات دنتواسکلتال، مطالعه حاضر با هدف مقایسه تاثیر این دستگاه با دستگاه modified fr ii (mf) بر روی بیماران cl ii/i مراجعه کننده به یک کلینیک خصوصی از سال 78 تا 82 انجام گرفت.مواد و روشها:...
We compare three 3CR samples of 11 FR 1 galaxies, 17 FR 2 galaxies and 18 lobe-dominated quasars contained in the ISO Data Archive. In contrast to the powerful FR 2 galaxies with edge-brightened lobes, the low radio power FR 1 galaxies in our sample do not exhibit any high MIR or FIR dust luminosity, which is typical for a buried, intrinsically more luminous AGN. This consolidates the fact alre...
BACKGROUND As the most abundant renewable resources, lignocellulosic materials are ideal candidates as alternative feedstock for bioethanol production. Cassava residues (CR) are byproducts of the cassava starch industry which can be mixed with lignocellulosic materials for ethanol production. The presence of lignin in lignocellulosic substrates can inhibit saccharification by reducing the cellu...
AIMS Tumor-specific targeted imaging is rapidly evolving in cancer diagnosis. The folate receptor alpha (FR-α) has already been identified as a suitable target for cancer therapy and imaging. FR-α is present on ~40% of human cancers. FR-β is known to be expressed on several hematologic malignancies and on activated macrophages, but little is known about FR-β expression in solid tumors. Addition...
Cardiac structures, function, and myocardial contractility are affected by food restriction (FR). There are few experiments associating undernutrition with hypertension. The aim of the present study was to analyze the effects of FR on the cardiac response to hypertension in a genetic model of hypertension, the spontaneously hypertensive rat (SHR). Five-month-old SHR were fed a control or a calo...
