Petro physics, rock physics and multi-attribute analysis have been employed in an integrated approach to delineate porosity variation across Tamag Field of Niger Delta Basin. Gamma and resistivity logs were employed to identify sand bodies and correlated across the field. Petro physical analysis was undertaken. Rock physics modelling and multi-attribute analysis were carried out. Two hydrocarbo...

Multi Criteria Decision Making (MCDM) is an advanced field of Operation Research; recently MCDM methods are efficient and common tools for performance evaluation in many areas such as finance and economy. The aim of this study is to show one of applications of mathematics in real word. This study with considering value based measures and accounting based measures simultaneously, provided a hybr...

Renal artery stenosis is a common cause of secondary hypertension with a rising incidence due to systemic atherosclerosis in an aging population. Patients with renovascular disease complicated by refractory hypertension, acute pulmonary edema, or progressive renal dysfunction benefit from aggressive medical therapy and may be considered for renal revascularization. Atherosclerotic renal artery ...

At the time when employees nowdays represent an important resource in achieving business success, there is an increasing focus on the process of recruitment and selection of personnel, because every company seeks to fill a vacant position with the best candidates, ie. those who best meet the requirements of the job. Therefore, this paper will propose an MCDM approach to the recruitment and sele...

In 1997, 248 urban university students in central Massachusetts rated responsibility for addiction using the Attributions of Responsibility for Addiction Scale (ARAS), developed for this study with university-based financial support. The vignette-based factorial design varied sex of drug user and type of addictive substance. Factor analysis yielded two subscales: internal and external responsib...

a key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. so, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. the x-ray diffraction patterns indicated that exfoliated ty...
