using the lennard-jones (12-6) potential, a new equation of state is obtained that can predict properties of both gases and liquids relatively well. this equation of state is given as (z-a)v2=(a/v2)-b, where z is the compressibility factor, a and b are constants, and a is an adjustable parameter that depends on the temperature, volume and the nature of the fluid, and its expressions depends upo...

this paper presents the results of a numerical study on the removal process of fluid particles under the influence of mixed convection in a horizontal channel with an open cavity. the bottom wall of the cavity is heated at a constant temperature (th), while the top wall is maintained at a relatively low temperature (tc). fluid with a uniform velocity (uo) and temperature (tc) is introduced into...

Kick occurrence is a possible event during a drilling process. It is required to be handled immediately using a well control method to avoid blowout, financial losses and damages to the drilling crew. Several methods including driller, wait and weight, and concurrent are applicable in the drilling industry to control a well during a kick incident. In this study, typical well control methods wer...

background: despite a high prevalence of endometriosis, there still exist many challenges in diagnosing the disease. this study aims to evaluate non-invasive and practical diagnostic methods by measuring serum and peritoneal fluid ca 125 levels in patients with endometriosis. a secondary aim is to determine the correlation between these markers with the stage of disease as well as the relations...

The corrosion definition is not constrained to alloy and metals, but rather the term, corrosion, can likewise be stretched out to earthenware production and other nonmetallic materials. Corrosion can prompt to problems significant in furthest fields for man-factory [1]. Corrosion gets to be distinctly a standout amongst the most difficult points for researchers and the society for building. Fro...
