The contractile state of smooth muscle (SM) reflects the ratio of activities of myosin light-chain kinase (MLCK) and myosin light chain phosphatase (MLCP), which determines the extent of regulatory light chain (RLC) phosphorylation and actin-activated myosin II activity and can be changed by modulating the activities of the calcium-calmodulin–dependent MLCK or of MLCP. Agonists through G protei...

This article examined the impact of cutting speed and feed rate on process cross with a saw chain. Three speeds three rates were chosen, their energy intensity was evaluated. The measurements performed an experimental device, which it is possible to set rpm (cutting speed) into section using frequency converters. influences resulting efficiency, at (vc) 5.02 m × s-1 power (P) 485 W. With increa...

This paper proposes a conceptual and measurement framework to quantitatively assess the disaster resilience of communities. The concept of resilience suggests a much broader framework than simply reducing monetary losses. Resilience can be conceptualized along four interrelated dimensions: technical, organizational, social, and economic. Evaluating community resilience and the degree to which m...

Amyloid deposits are a characteristic feature of the senile plaques identified in the brains of aged primates, individuals with Down's syndrome, and cases of Alzheimer's disease. The beta-amyloid protein (A beta), the principal component of amyloid, is a 4 kDa peptide derived from larger amyloid precursor protein(s) (APP). Four mRNAs, generated by alternative splicing of pre-mRNA derived from a...
