This paper presents a solution methodology for H∞-feedback control design problem of Heparin controlled blood clotting network under the presence stochastic noise. The formulaic procedure to solve nonlinear partial differential equation, Hamilton-Jacobi-Isaacs equation with Successive Galrkin’s Approximation is sketched and validity proved. According Lyapunov’s theory, solutions PDEs, robust fe...

aims: job rotation is considered as one of the human resource development methods. this study was carried out to investigate the correlation between job rotation and visiting number of environmental health employees. materials & methods: this descriptive cross-sectional study was done on environmental health employees in three health centers of north, north west and east of tehran in 2011. 42 p...

abstract: knee joint has major role in lower extremity activities. emong different elements of knee joint complex, anterior cruciate ligament has becom more interested because of its alignment, structural complication, varied never receptors and frequently susceptibility to injury. afterinjury of this ligament knee extensor torque decreases. the aim of this research was that reduce of quadricep...

Earlier we identified adenosine monophosphate (AMP) N(1)-oxide as a unique compound of royal jelly (RJ) that induces neurite outgrowth (neuritegenesis) from cultured rat pheochromocytoma PC12 cells via the adenosine A(2A) receptor. Now, we found that AMP N(1)-oxide stimulated the phosphorylation of not only mitogen-activated protein kinase (MAPK) but also that of cAMP/calcium-response element-b...

The relationship between changes in the myocardial concentration of adenosine 3':5'-cyclic monophosphate (cyclic AMP) and cardiac contractility was studied in guinea pig and rat myocardium. When isolated perfused guinea pig hearts were perfused with 10"M papaverine, a potent inhibitor of cyclic AMP phosphodiesterase activity, myocardial cyclic AMP concentration increased significantly from 1.7 ...

We propose a new transport paradigm, called asynchronous multicast push (AMP) that leads to much more efficient use of network bandwidth, to higher throughput, and to reduced server load. AMP decouples request and delivery for frequently requested data and uses multicast delivery. We derive quantitatively by how much the server load and the network load is reduced by introducing an asynchronism...

Abstract. Despite the importance of soil organic matter (SOM) in global carbon cycle, there remain many open questions regarding its formation and preservation. The study individual compound classes that make up SOM, such as lipid biomarkers including n-alkanes, can provide insight into cycling bulk SOM. While studies biomarkers, particularly have increased number past few decades, only a limit...

Abstract. Nitrogen oxides, classified as NOx (nitric oxide (NO) + nitrogen dioxide (NO2)) and NOy (NOx+ NO3, N2O5 HNO3, HNO4+ HONO Peroxyacetyl nitrate (PAN) organic nitrates any oxidized N compound), are important trace gases in the troposphere, which play an role formation of ozone, particulate matter (PM), secondary aerosols (SOA). There remain many uncertainties origin fate atmospheric comp...

The function of 5’-nucleotidase in nucleoside uptake from AMP was investigated in human lymphocytes by comparing the transport in cells containing this enzyme (5’N+) with that in cells deficient in the activity (5’N-). The rate of adenosine and P, uptake from AMP was 3.9-fold greater in the 5’N+ then in the 5’N lymphoc$tes. There was no difference in transport between these cells when incubated...
