This research aimed to obtain the petrophysical parameters of capillary pressure a sandstonefrom 3D modelling high-resolution rock images. By integrating number 2D slice results, plot capillarypressure vs water saturation was built. When performing digital simulations using 512 x pixels, theeffect on resulting image clearly seen interactive thresholding. The obtained porosity 29.5%while permeab...

there are two methods for identifying formation interface in oil wells: core analysis, which is a precise approach but costly and time consuming, and well logs analysis, which petrophysists perform, which is subjective and not completely reliable. in this paper, a novel coupled method was proposed to detect the formation interfaces using gr logs. second approximation level (a2) of gr log gained...

An efficient C0 continuous two dimensional (2D) finite element (FE) model is developed based on a refined higher order shear deformation theory (RHSDT) for the static analysis of soft core sandwich plate having imperfections at the layer interfaces. In this (RHSDT) theory, the in-plane displacement field for the face sheets and the core is obtained by superposing a globally varying cubic displa...

in the contact metamorphic aureole of the next to the granodiorite intrusive body in the hassan-abaad village of yazd, high frequency garnet in different metamorphic zones is notable, which some contain garnet crystal with obvious zoning. obtained data from core to rim of garnet by sem point analysis, show that garnet crystals belong to grandite series, and sharp variation of al and fe from cen...

The present study attempts to investigate the relationship between spatial configuration changes of Qom and the central core in the last half century. The main objective of this study is to review the Spatial form of Qom, and analyze the effect of changes in Urban configuration on the central core of the city and the main axes of urban activities during 1946 to 2011 and ultimately, Forecast the...

The mature core protein of the Hepatitis C virus (HCVC173) carrying pelB as a signal peptide (PelB::core) was overexpressed in Escherichia coli as 18% and 23.3% of the host’s total protein, in flask and fermentor cultivation, respectively. A final specific yield of 25 ± 1 mg HCVC173/g dry cell weight and an overallproductivity of 51±1 mg HCVC173/l/h were obtained in the stirred-tank ferme...

Buckling restrained braced frames (BRBFs) for seismic load resistance have been widely used in recent years. One of the key requirements for a buckling restrained brace is to sustain large plastic deformations under severe ground motions. The core of a buckling restrained brace is prone to fatigue fracture under cyclic loading. The earthquake induced fracture type of the core plate in a bucklin...
