The authority of the state to regulate the entry and residence of foreigners to it is characterized by a great deal of freedom, and it is limited only by the rules of international law that impose on states to respect the minimum standard in the treatment of foreigners, in order to achieve the optimum protection of human rights, regardless of the society in which they live, without consideration. Regarding his nationality or his country of origin, and whatever that may be, the foreigner has now become one of those addressed by the provisions of the law of the country in which he resides, and he enjoys the rights guaranteed by his human being, without regard to his country and nationality, in oth

Dictyostelium discoideum amoeba is a powerful system to study gene function through genetic and functional analysis. Paracaspase (Pcp) is a caspase-like protein that has recently identified in D. discoideum. Study paracaspase molecular function in Dictyostelium will provide insight into its cellular role in more complex organisms and the possibility to use it as a drug target against the parasitic amoeba. In this study, pcp was tagged with Green Fluorescent Protein (GFP) and over-expressed in the cell. The knockout version of pcp (pcp-) was also investigated. In the course of our examination, it was observed that cells overexpress Pcp was unable to complete the developmental process, leading us to examine its role in development. Those c

In this paper, some relations between the flows and the Enveloping Semi-group were studied. It allows to associate some properties on the topological compactification to any pointed flows. These relations enable us to study a number of the properties of the principles of flows corresponding with using algebric properties. Also in this paper proofs to some theorems of these relations are given.
