background: the earlier atomic bomb explosion in hiroshima and nagasaki, and three worth mentioning nuclear accidents - detonation at fukushima daiichi nuclear plant, chernobyl nuclear fallout and an accident at three mile island nuclear power plant have made us more worried about the secure exploitation of nuclear energy. the central focus of this paper is to review radiation-mediated health e...

A nozzle conŽ guration for the production of an intense and collimated supersonic cluster beam is presented and characterized by numerical modeling. A simple lens added to a cylindrical nozzle exploits aerodynamic focusing effects. The effect of the focalizing nozzle is an enrichment of the core of the jet with clusters of an arbitrary size interval depending on carrier gas pressure and tempera...

the main objective of this article is to examine the u.s. nuclear war plans, which have led to the transformation of the grand strategy of the united states since 1945, and they have also a significant impact on the nuclear programs of the nuclear – weapon states (nws), defense policies of nato and international security. research questions include: what are the similarities and differences in ...

in the framework of non-proliferation treaty (npt) it has been enumerated three objectives as follow: 1) peaceful use of nuclear energy; 2) non-proliferation of nuclear weapons and 3) nuclear disarmament. the writers in this article have studied and analyzed multilateral aspects of the right of peaceful use of nuclear energy, and interpretation of some npt articles (1, 2 and 4).in the conclusio...

Somatic cell nuclear transfer (SCNT or cloning) returns a differentiated cell to a totipotent status; a process termed nuclear reprogramming. Reproductive cloning has potential applications in both agriculture and biomedicine, but is limited by low efficiency. To understand the deficiencies of nuclear reprogramming, our research has focused on both candidate genes and global gene expression pat...

In this paper, we propose a dynamic lightpath con guration method for WDM ring network. With this method, lightpaths are established according to the congestion state of node and are released after some holding time. The performance of the proposed method is evaluated in light and heavy tra c cases. In the light tra c case, a single node in WDM ring network is modeled as a multiple queueing sys...

Background and objective: Clear Cell Renal Cell Carcinoma (CCRCC) is the most common adult renal neoplasm. Staging and grading of RCC are important predictors of survival. Fuhrman nuclear grading is widely used for CCRCC, the subjective nature of which has prompted more objective methods to evaluate nuclear features. Furthermore, Ki-67, a reliable marker of cellular pr...

bangladesh is one of the smaller states in asia. but it has a long and rich history of nuclear medicine for over sixty years. the progress in science and technology is always challenging in a developing country. in 1958, work for the first nuclear medicine facility was commenced in dhaka in a tin-shed known as ‘radioisotope centre’ and was officially inaugurated in 1962. since the late 50s of t...
