We apply the two-sector production function developed by Ram (1986) to estimate the threshold regression model for Iran, concerning the effect of government size on economic growth. Three government size indicators are used to find out the different threshold points. The results show a non-linear relationship of the Armey curve in Iran, in which the threshold effects corresponding to total gove...

One may find out the application‎ ‎of mathematics in the areas of ecology‎, ‎biology‎, ‎environmental‎ ‎sciences etc‎. ‎Mathematics is particulary used in the problem of‎ ‎predator-prey known as lotka-Volterra predator-prey equations.‎ ‎Indeed‎, ‎differential equations is employed very much in many areas‎ ‎of other sciences‎. ‎However‎, ‎most of natural problems involve some‎ ‎unknown functions...

background: assessment of national children growth has shown that a high percent of country's children are afflicted to growth failure. community participation is one of the principles of phc emphasized by who that is necessary for develop­ment of health services. the objective of this study was to develop a model for mother's participation in order to improving growth and nutrition of children...

Software Reliability Model is categorized into two, one is static model and the other one is dynamic model. Dynamic models observe the temporary behavior of debugging process during testing phase. In Static Models, modeling and analysis of program logic is done on the same code. A Model which describes about error detection in software Reliability is called Software Reliability Growth Model. Th...

b a s e don folic acid biosynthetic pathway a mathematical model was made for bacterial growth to describe the synergistic effect between sulfamethoxazole and trimethoprim. The results obtained show a strong synergism at growth inhibiting concentrations of these two drugs. Two cyclic pathways included in the model are responsible for this synergism. The roles of these pathways in producing ...
