Amino acid starvation of "stringent RNA control" (RC(str)) strains of Escherichia coli (E. coli) results in the cessation of net protein and net RNA synthesis, whereas "relaxed RNA control" (RC(rel)) strains continue net RNA synthesis under the same conditions of amino acid starvation. This report tests further the hypothesis that net RNA synthesis is markedly reduced during amino acid starvati...

Cytotoxic ribonucleases with antitumor activity are mainly found in the oocytes and early embryos of frogs, and share sequence similarity with each other. They all belong to the RNase A superfamily but possess different cytotoxicities, base specificities and ribonucleolytic activities. RC-RNase 4, one of the five novel ribonucleases isolated from the oocytes of Rana catesbeiana, is a 106 amino ...

Carbon fiber reinforced polymer (CFRP) sheets are externally bonded to reinforced concrete (RC) members to provide additional strength such as flexural, shear, etc. It has been widely accepted that carbon fiber reinforced polymers (CFRPs) can be used effectively to strengthen reinforced concrete (RC) members. This paper is intended to study and use externally bonded CFRP strips to repair and st...

This paper describes a method of performance evaluation and remaining life prediction for an aged reinforced concrete (RC) T-girder bridge by J-BMS RC version via close visual inspection data, and also verifies the assessment results obtained as outputs from the Bridge Rating Expert System (RC-BREX) which is a subsystem of the J-BMS, to evaluate the effectiveness of the system. The Bridge Manag...

Region covariance (RC) descriptor is an effective and efficient feature for visual tracking. Current RC-based tracking algorithms use the whole RC matrix to track the target in video directly. However, there exist some issues for these whole RCbased algorithms. If some features are contaminated, the whole RC will become unreliable, which results in lost object-tracking. In addition, if some fea...

Despite the increasing numbers of Americans who die in nursing homes (NHs) and residential care/assisted living (RC/AL) facilities, and the importance of religious and spiritual needs as one approaches death, little is known about how these needs are met for dying individuals in long-term care (LTC) institutional settings. This study compared receipt of religious and spiritual help in four type...

We study the linearized stability of shear flow satisfying Navier slip boundary conditions. The Orr-Sommerfeld equation for the plane Poiseuille flow with Navier slip boundary conditions is solved numerically by the Chebyshev collocation method. Our numerical results show that slip at the boundary increases the critical Reynolds number Rc for instability. The dependence of the this critical Rey...

The temperature dependence of the magnetic viscosity coefficient (Sv), the activation volume (Vact) and the coercivity (Hc) were examined for CoCrTa/Cr and CoCrPtTa/Cr thin films in the temperature range from 200 to 423 K. This experiment shows that the medium noise measured for 150 kFCI is approximately proportional to kT/Sv (=Vact X Ms) at 298K. kT/Sv and the temperature variation of coercivi...
