The rates of synthesis of ribosomes, 5S RNA, and tRNA necessary to maintain the steady-state concentrations of these entities in liver cytoplasm of adult rats were determined. On the average, each liver cell in the adult rat synthesizes 650 ribosomes, 650 molecules of 5S RNA, and 11,000 molecules of tRNA each minute. The numbers of genes per liver cell for rRNA, 5S RNA, and tRNA were 330, 1660,...

The pyrolysis of hazelnut shell, polyethylene oxide and their blends were carried out catalytically at 500 and 650 oC. Potassium dichromate was chosen according to its oxidative characteristics and decomposition temperature (500 oC) where decomposition products are CrO3 and K2CrO4. As a main effect, a remarkable increase in gasification was observed using this catalyst for pure components and b...

Coxiella burnetii, the agent of Q fever in humans, has been associated with abortion in cattle. In this study 650 sera from cattle with abortion and 600 randomly-selected control sera were examined for antibodies to C. burnetii by ELISA. Two hundred and ninety-two (44.9%) out of 650 animals which experienced abortion were seropositive versus 132 (22%) out of 600 of the control group. A statisti...

The catalytic decomposition of N2O was investigated over Cu-Zn/ZnAl2O4 catalysts in the temperature range of 400–650 ◦C Catalytic samples have been prepared by wet impregnation method. Prepared catalysts were characterized using several techniques like BET surface area, X-ray diffraction (XRD), and Scanning electron microscopy (SEM). The Cu-Zn/ZnAl2O4 showed higher catalytic performance along w...

We report on results of a Time-of-Flight, TOF, counter prototype in beam tests at SLAC and Fermilab. Using two identical 64-pixel Photonis Microchannel Plate Photomultipliers, MCP-PMTs, to provide start and stop signals, each having a 1 cm-long quartz Cherenkov radiator, we have achieved a timing resolution of σSingle_detector ~14 ps. To be published in Nucl. Instr.& Methods ——— • Manuscript re...

Water-soluble metal working fluids are used for processing of aluminum alloy materials. This short article describes properties of new additives in water-soluble metal working fluids for aluminum alloy materials. Many half esters or diesters were prepared from the reactions of higher alcohols with acid anhydrides. Interestingly, diesters of PTMG (tetrahydrofuran oligomer, MW = 650 and 1000) and...
