Band-shifting and DNase I footprinting analyses detected a specific DNA binding protein extracted from oviduct nuclei that binds to the ovalbumin gene 5' sequence between -1094 and -1125. This "-1100" fragment, when inserted upstream of the SV40 or ovalbumin promoters fused to a chloramphenicol acetyltransferase reporter gene, enhances chloramphenicol acetyltransferase activity 5-10-fold follow...

Multi-point forming (MPF) is an advanced and flexible method to form sheet metal workpieces. Although there are studies investigating different aspects of this method, the on effects pin diameter contact MPF insufficient. In study, pins with diameters 10, 12, 14 mm were used investigate damage factor, effective stress distribution, required loads three forms aluminum 1100 parts in finite elemen...

This paper describes a microparticle delivery device that generates a plasma jet through laser ablation of a thin metal foil and uses the jet to accomplish particle delivery into soft living targets for transferring biological agents. Pure gold microparticles of 1 µm size were coated with a plasmid DNA, pIG121Hm, and were deposited as a thin layer on one surface of an aluminum foil. The laser (...

Purpose.Influence of preheating temperature and sodium silicate solute content in sand-sodium-silicate mixtures structured by SMS-process on their destruction work under knock loading action has been established. Methodology. Quartz sand brand 1K2O202, water, with specific gravity 1.42…1.44 g/cm3 modulus 2.8… 3.0 have used this work. Mixtures structuring realized microwave furnace frequency 2.4...

Welding is a suitable and better process to manufacture complex objects for aerospace, naval, automotive structures. Service conditions complexity in load acting force the manufactures make joints between dissimilar materials. Thus, there need efficient welding techniques form sound an understanding of imperfections their effects. In this study attempt has been made joining feasibility aluminum...

The formation of intermetallic compounds (IMC) at the Al/Fe interface determined mechanical property steel-aluminum welded joint. To understand interfacial microstructure evolution and relate diffusion mechanism atoms cross interface, effect welding parameters on IMC was studied, molecular dynamics method (MD) used to simulate process Al Fe atoms. Four temperatures (950 K, 1000 1050 1100 K) wer...

PURPOSE To assess whether a fluoride dose response could be detected with a relatively small sample size in a short duration using a novel randomized, double-blind study design. METHODS Subjects (N = 644, with approximately 215 per group) with a mean age of 10.4 years old (9-12 years old) used a placebo dentifrice, an 1100 ppm F dentifrice or a 2800 ppm F dentifrice for the first 9 months of ...
