Context:In this review, we discuss empirical and stoichiometric models, which have been developed recently in SSF processes and the influence of environmental conditions on the variables of these models. Additionally, new studies on modeling of product formation are also mentioned. <span style="color: windowtext...

orography plays a substantial role in the formation and evolution of many atmospheric phenomena. observations indicate that two mountain ranges to the southwest of the red sea and west of iran (zagross mountain range) play a crucial role in the formation, evolution and activities of synoptic weather systems over iran. observations also, indicate that there are considerable differences between t...

the “driving force - pressure - state - impact – response” modeling framework isadopted to consider the formation mechanisms of environmental risks and the requirements ofecological environment protection. moreover, a systematical index system and evaluation model forthe measurement of the coastal ecological security level is put forward in this paper to assess thestate of coastal ecological en...

ZnO/activated carbon nanocomposites (ZnO/ACns) were synthesized by applying two different solid-state and precipitation methods. Precipitation method was initiated with zinc chloride and sodium hydroxide as starting materials in the presence of activated carbon. The synthesized sample was calcined at 250 °C for 1 h. The preparation of nanocomposite by solid-state method was accomplished by heat...

state divisions are one of the most effective tools for political space organizing. the background of dividing the territory of the country into smaller units in iran may be historically traced back to the formation of the first territorial state by achaemenids. the role and function of state divisions, its relationship to national survival, facilitation of exerting the government’s will, a bal...

in 1930s, the idea of providing general welfare and welfare state appeared in industrial countries due to the belief in the ability of left forces in solving misfortunes that people entangled in; because of financial crisis in industrialized societies, expanded poverty, starvation and epidemic diseases which led millions of people to the hopelessness. welfare states achieved outstanding success...
