The current study has been performed with the purpose of investigating hot papers of Middle-East countries in database of Essential Science Indicators (ESI). Number of hot papers of each country was identified and the result showed that among 19 countries located in middle-east region only 9 of them have hot papers, and Turkey has been assigned the first rank in this region regarding the number...

[1] Hydrographic transects suggest an eastward flow with a subsurface core along the entire southern boundary of the Caribbean Sea. The transport of the coastal limb of the Panama-Colombia Gyre (PCG), known as the Panama-Colombia Countercurrent, decreases toward the east (from 6 Sv off Panama), as water is lost into the recirculation of the PCG. Off Panama, the flow is strongest at the surface,...

Recently many researches have studied technological innovation capabilities (TICs) and their impacts on firm’s competitive performance in the field of manufacturing industries. This paper pursued Yam et al. (2004) framework to study the relevance of TICs and firm's competitive performance in a mainly-service-based industry in Iran (ICT). Empirical data were collected through a questionnaire from...

translation studies have become an accepted academic subject and books, journals and doctoral dissertations appear faster than one can read them all (bassnet and lefevere, 1990). but this field also brought with itself so many other issues which needed to be investigated more, in the heart of which, issues like ideology, ethics, culture, bilingualism and multilingualism. it is reported that ove...

One of the most important problems in research and applied fields of production management is a suitable scheduling for different operations. So, there are many approaches for job workshop or job non-workshop scheduling problems. Since job workshop scheduling problems (JSP) belong to NP-Hard class, some metaheuristics methods such as Tabu Search, Simulated Annealing, Genetic Algorithm and Parti...

The Ruedenberg type formula relating the total molecular energy to the sum of orbital energies is examined by using SCC-MO and ab initio D Z M O eigenvalues. Comparison with rigorous ab initio D Z energy expectation values indicates that Ruedenberg 's formula in its original form can not provide semiquantitative information on molecular energetics. Much more promissing in this respect is the el...

The lifetime of the b Pu(v51) state in N2 has been determined experimentally using a laser-based pump–probe scheme and an exceptionally long lifetime of 2.61 ns was found. Semiempirical close-coupling calculations of the radiative lifetime, which include Rydberg–valence interactions in the singlet manifold, are consistent with this large value, giving a value of 3.61 ns and suggesting a prediss...

به طور کلی در فرآیندهای مارکوف ارگودیک دو بعدی یافتن فرم بسته توزیع ایستا، تنها برای حالات خیلی خاص امکان پذیر است. با توجه به این مشکل و نیز با توجه به اهمیت توزیع ایستا، بررسی و مطالعه رفتار مجانبی توزیع ایستای این فرآیندها مورد توجه قرار گرفته است. زنجیر قدم زدن تصادفی دو بعدی که در برخی متون به آن، فرآیند qbd دو طرفه نیز می گویند، یکی از این فرآیندها است. یک فرآیند qbd زمان گسسته یک زنجیر م...

The rotational barrier about the C S bond in fluorocarbonylsulfenyl chloride [FC(0)SC1] is investigated using the C N D O method. The results confirm the existence of planar eis and trans conformers and the higher stability of the latter, as suggested by previous vibrational results. The valence force constants in FC(0)SC1 were also calculated and the values obtained compare favourably with res...

Although initially originated as a totally empirical relationship to explain the volume of trade between two partners, gravity equation has been the focus of several theoretic models that try to explain it. Specialization models are of great importance in providing a solid theoretic ground for gravity equation in bilateral trade. Some research papers try to improve specialization models by addi...
