This paper presents a complete dynamic analysis of roller and vane of a rotary compressor widely used for air-conditioners. An approach and a set of equations are developed estimating the type of motion at vane tip and roller interface and calculating the frictional force in accordance with the motion type. The forces on roller caused by relative motion between roller and cylinder wall are anal...

In this study, a site-specific immunoconjugate, designated CYT-356, of the prostate-reactive monoclonal antibody 7E11-C5 was characterized by immunohistological methods for reactivity with normal and neoplastic human tissues. In addition, CYT-356 labeled with 111In was assessed by in vivo imaging and pharmacokinetic studies for localization to human tumor xenografts in nude mice. The native ant...

Ammonia (NH3)-oxidizing bacteria (AOB) derive total energy for life from the multi-electron oxidation of NH3 to nitrite (NO2 ). One obligate intermediate of this metabolism is hydroxylamine (NH2OH), which can be oxidized to the potent greenhouse agent nitrous oxide (N2O) by the AOB enzyme cytochrome (cyt) P460. We have now spectroscopically characterized a 6-coordinate (6c) {FeNO} intermediate ...

Roller skis are used by cross-country skiers, biathletes and ski-orienteers for their snow-free training and in roller ski competitions. Additionally, much of the current sports research into the physiology and biomechanics of crosscountry skiing is conducted indoors on treadmills using roller skis. For elite athletes, the differences in performance are quite small, thus emphasising the importa...

Many RNA viruses express part of their genomic information by read-through over internal termination codons. We have recently characterized tobacco cytoplasmic (cyt) and chloroplast (chl) tRNACmCATrp and tRNAGCACys as natural suppressor tRNAs that are able to read the leaky UGA codon in RNA-1 of tobacco rattle virus, albeit with different efficiencies. Here we have identified a third natural UG...

The aim of this project is to develop methods for scaling up roller compaction process from lab scale to pilot scale, to determine the effect of processing parameters of roller compactors at both lab scale (instrumented roller compactor at University of Birmingham, micro-pactor at Pfizer) and pilot scale (mini-pactor from Gerteis) on the attributes of dry-granulated formulations, including the ...

Abscisic acid (ABA) induces production of reactive oxygen species (ROS) and nitric oxide (NO), elevation of the cytosolic free calcium ion concentration ([Ca(2+)](cyt)) and cytosolic pH (pH(cyt)), and activation of S-type anion channels in guard cells, causing stomatal closure. To investigate whether Arabidopsis Two pore channel 1 (AtTPC1) that encodes the slow vacuolar (SV) channel is involved...
