The Visible to Infrared SASE Amplifier (VISA) FEL is designed to obtain high gain at a radiation wavelength of 800 nm. The FEL uses the high brightness electron beam of the Accelerator Test Facility (ATF), with energy of 72MeV. VISA uses a novel, 4m long, strong focusing undulator with a gap of 6mm and a period of 1.8 cm. To obtain large gain the beam and undulator axis have to be aligned to be...
Frequency domain channel propagation measurements in the 800-1000 MHz band have been performed with ground-lying antennas. The range of path-loss exponent and shadowing variance for indoor and outdoor environment were determined. The range of these values roughly agree with those measured for higher elevation antennas. Frequency selectivity of the RF channel was also characterized by means of d...
The deuteron sepctra from {n,d) reactions at 800 MeV near 0' are characterized by a high energy quasielastic scattering peak, and at lower momentum, a quasifree scattering peak. The ratio of the quasifree to quasielastic cross sections is approximately 10:1.Both cross sections exhibit an A '" mass dependence over the range of target nuclei studied. Comparisons are made with corresponding proton...
LLE Review, Volume 126 59 Introduction The transition of an insulator to a metal (metallization) at high compression is generally the result of pressure-induced closure of the band gap.1–4 Lithium fluoride’s (LiF’s) largeband-gap and ionic crystalline structure produces its uniquely high ultraviolet transmissivity. Two rare-gas solids, He and Ne, have anomalously high metallization pressures be...
OBJECTIVE Sinemet, a combination drug containing carbidopa and levodopa is considered the gold standard therapy for the treatment of Parkinson's disease (PD). When approved by the Food and Drug Administration (FDA) in 1988, a maximum daily dosage limit of 800 mg (eight tablets) of the 25/100 carbidopa/levodopa formulation was introduced. Overall, the FDA approval was a historic success; however...
The activity of chymosin, plasmin, and Lactococcus lactis enzymes (cell envelope proteinase, intracellular peptidases, and glycolytic enzymes) were determined after 5-min exposures to pressures up to 800 MPa. Plasmin was unaffected by any pressure treatment. Chymosin activity was unaffected up to 400 MPa and decreased at 500 to 800 MPa. Fifty percent of control chymosin activity remained after ...
در این تحقیق، تغییرات ریزساختار سوپر آلیاژ in792 در اثر تغییر سرعت سرد کردن از دمای انحلال جزیی و تاثیر آن بر خواص کششی و خواص خزشی این آلیاژ بررسی شده است. کنترل متغیرهای عملیات حرارتی در حین فرآوری سوپر آلیاژهای پایه نیکل منجر به حصول زیرساختار و خواص مکانیکی بهینه سوپر آلیاژ می گردد. سرعت سرد کردن از دمای انحلال نیز به عنوان یکی از این متغیرها می تواند چنین اثری داشته باشد. به منظور بررسی تا...
The Beckman Coulter UniCel® DxH 800 is a hematology analyzer incorporating new electronic and mechanical design with advanced algorithm technology to perform CBC, white blood cell (WBC) differential, nucleated red blood cell (NRBC), and reticulocyte analysis. Evaluation of this instrument was performed in our 800-bed tertiary care hospital and specifically centered upon the correlation of WBC, ...
The study was couducted to investigate the effects of gamma irradiation and CO₂ on flavonoid content and leaf gas exchange in C.asiatica. For flavonoid determination, the design was a split split plot based on Randomized Complete Block Design (RCBD). For other parameters, the designs were split plots. Statistical tests revealed significant differences in flavonoid contents of Centella asiatica ...
Tree sparrows (Passer montanus) are widely distributed in all seasons in many countries. In this study, a survey and relevant experiments on avian influenza (AI) in tree sparrows were conducted. The results suggested that the receptor for avian influenza viruses (AIVs), SAα2,3Gal, is abundant in the respiratory tract of tree sparrows, and most of the tree sparrows infected experimentally with t...
