growing process of industrialization in different societies, excessive expansion of industries and factories and increase transport industries, push human toward unstable development. among these problem, massive volume of pollutions is also added to the atmosphere. air pollution in industrial societies and cities is more intensive. global warming is one of the major problems of 21 century. co2...
1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
[Purpose] This study was conducted to investigate the effects of the push-up plus while using a balance ball, a sling, and a sling with a pulley in a creeping position on an unstable floor. [Subjects and Methods] The subjects were divided into three groups of 15 members each who performed the different three type methods of push-up plus (with scapulae protruding) in a random order while in a cr...
We describe a number of pitfalls that may occur with the push to rapidly expand access to antiretroviral therapy in sub-Saharan Africa. These include undesirable opportunity costs, the fragmentation of health systems, worsening health care inequities, and poor and unsustained treatment outcomes. On the other hand, AIDS "treatment activism" provides an opportunity to catalyze comprehensive healt...

we consider the semilinear elliptic boundary value problem = ∈∂ω− δ = ∈ωu x xu x f u x x( ) 0;( ) λ ( ( ));where λ > 0 is a parameter, ω is a bounded region in rn with a smooth boundary, and f is asmooth function. we prove, under some additional conditions, the existence of a positive solution for λlarge. we prove that our solution u for λ large is such that = →∞∈ω|| u ||: sup| u(x) |xas λ ...
10kV linked SVG module power supply from their own h-bridge power, supply is unstable. To solve this problem, this paper proposes a new way to take power, using a combination of full-bridge push-pull circuit with isolation transformer to solve the logical drive power between the power module and the SVG device self-consistent problem. The paper detailed analysis of the working principle and cha...
