This work reviews the development of computational fluid dynamics （CFD） modeling for hydrogen separation, with a focus on high temperature membranes to address industrial requirements in terms of membrane systems as contactors, or in membrane reactor arrange- ments. CFD modeling of membrane,.s attracts interesting challenges as the membrane provides a discontinuity of flow, and therefore cannot be solved by the Navier-Stokes equations. To address this problem, tile concept of source has been introduced to understand gas flows on both sides or domains （feed and permeate） of the membrane. This is an important solution, as the gas flow and concentrations in the permeate domain are intrinsically affected by the gas flow and concentrations in the feed domain and vice-versa. In turn, the source term will depend on the membrane used, as different membrane materials comply with different transport mechanisms, in addition to varying gas selectiv- ity and fluxes. This work also addresses concentration polarization, a common effect in membrane systems, though its significance is dependent upon the performance of the membrane coupled with the operating conditions. Finally, CFD modeling is shifting from simplified single gas simulation to industrial gas mixtures, when the mathematical treatment becomes more complex.

A new series of quinoxalinophenazine derivatives were synthesized in good yields by the reaction of 2,3-dibromonaphthalene-1,4-dione with different aryl-1,2-diamines in DMF as solvent at 120-130℃ or under reflux conditions. 3,12-dimethylbenzo[a]quinoxalino[2,3-c] phenazine with bidentate character reacts with mercury（II） bromide to give suitable crystals. All products were confirmed by IR, ^1H and ^13C NMR, and the metal complex by single-crystal X-ray method. The crystal（C24H16Br2HgN4, Mr = 720.82） belongs to the triclinic system, space group P1 with a = 10.186（6）, b = 10.421（6）, c = 11.470（7） A, α = 98.670（7）, β = 95.069（7）, γ = 109.831（7）°, V = 1119.4（12） A3, Z = 2, Dc = 2.139 Mg/m^3, μ = 10.46 mm^-1, F（000） = 676, R = 0.043 and wR = 0.115 for 3982 observed reflections with I 〉 2σ（I）.

Background: The use of traditional and complementary medicine (T&CM) is increasing in both developed and developing countries. The school of Persian medicine (PM) in Iran is a comprehensive medical school that is rich in history and has its own special principles, elements, philosophy, and diagnostic and treatment options. Many complementary therapy modalities are also popular and in demand among patients and physicians. The aim of this paper is to provide logic for the policymakers in Iranian medical education to make changes in medical education curricula, particularly on integrating T&CM. Methods: We reviewed the global experience in teaching T&CM to medical students, and highlighting the strengths of PM, described why it is necessary to integrate T&CM into general medicine curricula in Iran. Results: PM is a traditional system of medicine that dates back about 7000 years. Although there are few studies about the safety and effectiveness of PM, research into it has recently been accelerated. There is a suitable opportunity for integrating T&CM with conventional medicine. Physicians should be familiar with T&CM to avoid any contraindications, interactions, and unwanted effects. Conclusion: Traditional medicine is part of Iran's heritage and. thus, needs special attention. Familiarization of physicians with T&CM can help them choose the best treatment options for their patients. To integrate T&CM into the medical education curricula of Iran, a two-credit course has been proposed for implementation across the country.

Semnan province is one of the vast provinces of the country that has a variety of topographical and clamatorial conditions. This province plays a key role in industrial, agricultural and animal husbandry activities. The study of its climate potential with respect to its natural limitations like lack of water resources, soil types, droughts and desertification problems has been considered as a necessity in the province annual planning. In this study, the climatic regionalization of the province is done through using empirical and quantitative methods on climatic data of meteorological stations of the area in statistical period of 1982-2005. Methods of Koppen empirical, De Martonne, Emberger and Dr Karimi have divided the province into 3, 2, 4 and 6 climactic types, respectively. Using principle components and the cluster analysis on 14 climatic elements of 21 stations, 5 climatic types have been specified for the province. Based on this method, temperature, its Diurnal Temperature Range (DTR), precipitation and its type, and humidity contribute a great deal to the climate of the Semnan Province. The main results of this identification of 5 climatic types include hot & dry, dry & hot semi-dry, dry & cold semi-dry, mountainous, and Caspian climate.
