A new thermo-regulator

DYNAMIC SIMULATION OF A HIGH PRESSURE REGULATOR

In this paper, the dynamic simulation for a high pressure regulator is performed to obtain the regulator behavior. To analyze the regulator performance, the equation of motion for inner parts, the continuity equation for diverse chambers and the equation for mass flow rate were derived. Because of nonlinearity and coupling, these equations are solved using numerical methods and the results are ...

A New Ozone Concentration Regulator

Laboratory design of an ozone concentration regulator which is build on the theory of continuity equation for gas flow in parallel pipes in conjunction with the ozone elimination potentials of an ozone destructor is presented. At an initial oxygen flow rate of 33.33 cms, ozone concentration was generated and varied between 429.30 parts per million (ppm) to 3826.60 ppm. Similarly at an initial o...

Concerted Actions of a Thermo-labile Regulator and a Unique Intergenic RNA Thermosensor Control Yersinia Virulence

Expression of all Yersinia pathogenicity factors encoded on the virulence plasmid, including the yop effector and the ysc type III secretion genes, is controlled by the transcriptional activator LcrF in response to temperature. Here, we show that a protein- and RNA-dependent hierarchy of thermosensors induce LcrF synthesis at body temperature. Thermally regulated transcription of lcrF is modest...

New complement regulator exposed.

Homozygous deletion of a 84-kb genomic fragment in human chromosome 1 that encompasses the CFHR1 and CFHR3 genes represents a risk factor for hemolytic uremic syndrome (HUS) but has a protective effect in age-related macular degeneration (AMD). Here we identify CFHR1 as a novel inhibitor of the complement pathway that blocks C5 convertase activity and interferes with C5b surface deposition and ...
