CspA is a major cold shock-inducible protein (70 aa), and its major role in the cold shock response was shown to be as an RNA chaperone destabilizing secondary structure of mRNAs at low temperature. Previously, we showed that the overexpression of mutant cspA containing premature non-sense codons at various positions led to stalled ribosomes on mutant cspA transcripts, ultimately leading to cel...

Sir,?I should be much obliged if you, or any of your I. M. S. readers in military employment, would kindly give information on the following points of dress for the Indian Medical Service. The dress regulations are out of print and it is almost impossible to obtain authoritative information regarding them 1. What badges are worn on tl}? collars of the blue serge coat and frockcoat? 2. Should th...

In Lactobacillus casei ATCC 393, the chromosomally encoded lactose operon, lacTEGF, encodes an antiterminator protein (LacT), lactose-specific phosphoenolpyruvate-dependent phosphotransferase system (PTS) elements (LacE and LacF), and a phospho-beta-galactosidase. lacT, lacE, and lacF mutant strains were constructed by double crossover. The lacT strain displayed constitutive termination at a ri...

New policies have been implemented at radio station WSND in response to the controversy arising from last September’s broadcast of the “ Radio Free Notre Dame ” program. WSND’s general manager Jim O’Brien worked with the ad m in is tra tio n to insure that a repeat of this incident could not occur. “ Things are working out well now and relations with the administration couldn’t be too much bett...

The behavior of stone groundwood / polypropylene injection-molded composites was evaluated with and without coupling agent. Stone groundwood (SGW) is a fibrous material commonly prepared in a high yield process and mainly used for papermaking applications. In this work, the use of SGW fibers was explored as a reinforcing element of polypropylene (PP) composites. The surface charge density of th...

The paper presents review of research work experimental investigation on polypropylene fibre reinforced concrete and concrete with artificial sand. Use of fiber reinforce polymer in civil engineering increase rapidly. Various type of fiber is used such as glass, carbon, steel, asbestos, polyester and polypropylene. The various experimental investigations for determination of properties of polyp...

the effect of impact modifier on creep behavior of wood flour- recycled polypropylene composites has been evaluated in this work. for this purpose, impact modifier (ethylene vinyl acetate) and recycled polypropylene were mixed with wood flour (50/50% w/w) as well as the impact modifier (0, 3%, 6% and 9%) by a counter-rotating twin-screw extruder to manufacture the wood flour- recycled polypropy...

Alpha-grass was studied as the reinforcement in a starch-based polymer matrix. Mater-bi®-Y was chosen as a matrix due to its Young’s modulus, in line with that of polypropylene. The test specimens were injection molded and tensile tested. The obtained results were compared to glass fiber reinforced polypropylene. The reinforcing fibers increased the Young’s modulus significantly, obtaining valu...
