A number of physicists have urged the development of a workable light-front (LF) Hamiltonian formulation of QCD [1]. Such a quantisation scheme would yield Lorentz-boost-invariant wavefunctions having a natural constituent structure, providing a power tool in the analysis of hadronic physics. The most obvious applications include inclusive and exclusive hard scattering, and weak and electromagn...

background: the horror of hiv/aids as a non-curable, grueling disease is a destructive issue for every country. drug use, shared needles and unsafe sex are closely linked to the transmission of hiv/aids. modification or changing unhealthy behavior through educational programs can lead to hiv prevention. the aim of this study was to evaluate the efficiency of theory-based education intervention ...

We investigate the gauged NJL–model in curved spacetime using the RG formulation and the equivalency with the gauge Higgs–Yukawa model in a modified 1/N c –expansion. The strong curvature induced chiral symmetry breaking is found in the non-perturbative RG approach (presumably equivalent to the ladder Schwinger–Dyson equations). Dynamically generated fermion mass is explicitly calculated and in...

This paper reviewed the secure characteristics of mobile devices that can use wireless networks almost anywhere and anytime by using one or more wireless network technologies. These technologies enable the use of infrastructured networks and ad-hoc networks. Further it describes the characteristics o f wireless ad-hoc networks and the environment for the different possible gateway implementatio...

In the existing system, the problem of TCP in MANET’s environment is packet losses induced by network congestion. In case if congestion occurs it leads to the loss of data. In the proposed system, Blue algorithm is used for avoiding packet loss in TCP with wireless network based on checking size of queue. If the size of queue is maximum, gateway directly forwards the packet to destination throu...

Addiction to cocaine is commonly preceded by experiences with legal or decriminalized drugs, such as alcohol, nicotine, and marijuana. The biological mechanisms by which these gateway drugs contribute to cocaine addiction are only beginning to be understood. We report that in the rat, prior alcohol consumption results in enhanced addiction-like behavior to cocaine, including continued cocaine u...

Journal compilation © 2006 Society for the Study of Addiction Addiction, 101 , 470–476 Deciding which of these causal pathways explains the relationships between cannabis and other illicit drug use will depend upon a convergence of evidence from a variety of sources, such as: animal studies of the plausibility of pharmacological mechanisms (e.g. [7]); studies of twins discor...
