This paper has examined the phenomenon of convergence of per capita out put levels across the IC countries for the 1960-1998 periods. Three concepts of convergence, i.e., sigma beta and relative beta, have been used. The estimated beta values reveals only a very weak convergence (?=.0014) across IC for 1960-1998 period. But when a more homogeneous group of countries were selected, the results s...

background: the complicated concept of quality of life (qol) has been considered as an important criterion for health outcomes in chronic diseases, such as heart disease, in recent years. the aim of this study was to evaluate the qol of patients with angina pectoris after treatment with enhanced external counterpulsation (eecp). methods and materials: this quasi-experimental study was conducted...

purpose : to report the evaluation of the treatment response in choroidal hemangioma with application of enhanced depth imaging optical coherence tomography (edi-oct) technique case report : a 73-year-old woman with a circumscribed choroidal hemangioma in the posterior pole of her left eye underwent photodynamic therapy and intravitreal injection of bevacizumab. edi-oct obtained from the affect...

in this work, an environmentally friendly sample pre-treatment method, ultrasound assisted surfactant enhanced emulsification microextraction (uaseme) followed with spectrofluorimetry was performed for determination of oxadiazon residues in water samples. after the determination of the most suitable extraction solvent and its volume, other parameters such as type and concentration of surfactant...

in this paper, a simplified formulation for compositional reservoir simulator is presented. these types of simulators are used when inter-phase mass transfer depends on phase composition as well as pressure. the procedure for solving compositional model equations is completely described. for equilibrium calculation, property estimation peng robinson equation of state is used. this equation was ...

recently, a renewed interest arises in the application of nanotechnology for the upstream petroleum industry. in particular, adding nanoparticles to fluids may drastically benefit enhanced oil recovery and improve well drilling, by changing the properties of the fluid, rocks wettability alteration, advanced drag reduction, strengthening the sand consolidation, reducing the inter-facial tension and...

in this paper, several $delta$ and strong convergence theorems are established for the ishikawa iterations for nonexpansive mappings in the framework of cat(0) spaces. our results extend and improve the corresponding results

Intraseasonal oscillation (ISO) is the dominant variability during Indian summer monsoon (ISM). In this study, it found that ISOs accompanying intraseasonal rainfall are substantially enhanced over northeastern Arabian Sea (AS) in past three decades. The rise agrees with variation moisture loading. strengthening of wind convergence planetary boundary layer (PBL) triggers changes vertical veloci...

The main purpose of this paper is to establish different types of convergence theorems for fuzzy Henstock integrable functions, introduced by  Wu and Gong cite{wu:hiff}. In fact, we have proved fuzzy uniform convergence theorem, convergence theorem for fuzzy uniform Henstock integrable functions and fuzzy monotone convergence theorem. Finally, a necessary and sufficient condition under which th...
