wettability alteration is an important method for increasing oil recovery from oil-wet carbonatereservoirs. chemical agents like surfactants are known as wettability modifiers in carbonate systems.oil can be recovered from initially oil-wet carbonate reservoirs by wettability alteration from oil-wetto water-wet condition with adding dilute surfactant and electrolyte solutions. this paper invest...

Abstract Introduction The influence of animal strain on psoriasis model development by imiquimod (IMQ) has been studied in Balb/c and Swiss mice. Materials Methods Female mice either were challenged with 5% IMQ (62.5 mg back skin, 10 right ear). They observed for the severity disease using Psoriasis area index (PASI), splenomegaly, histopathological alterations. To validate model, well-establis...

One of the most important characteristics of annular arrays is their superior focal capabilities. In order to achieve the desired focussing, each of the elements is fired in different times. The delay times used for beam focussing are called focal laws. The focal laws are automatically calculated from the inspection software. In order to make sure that the focal laws are calculated correctly fr...

Modern production of structural parts in the aeronautic industry is characterized by mechanically optimized structures that can be complicated to inspect due to complex geometries and/or complex materials. Developing NDT procedures is thus more challenging and could become costly without tools to help NDT design and performance predictions. Simulation is a major asset to help engineers to evalu...

Traditional online wheel-set ultrasonic inspection method and inspection technology can not meet the new requirement of High Power Locomotive wheel-set online. In this article, features of locomotive wheel and defect distribution are analyzed, and a more strictly online inspection requirement is put forward. Based on which, an optimized multi arrangement of phased array and conventional ultraso...

ABSTRACT Vitiligo is a dermatological disease affecting both animals and humans. It characterized by depigmented macules of varying shape size, originated from melanocyte destruction. Even though there are some theories tackling causation, etiopathology not yet certain. Moreover, lesion areas can either increase or diminish over time, therefore, available treatment alternatives tend to prove in...

efforts to enhance oil recovery through wettability alteration by nanoparticles have been attracted inrecent years. however, many basic questions have been ambiguous up until now. nanoparticlespenetrate into pore volume of porous media, stick on the core surface, and by creating homogeneouswater-wet area, cause to alter wettability. this work introduces the new concept of adding znonanoparticle...

The aim of the current research was to investigate the effect of aluminum exposure on humoral immunity (immunoglobulin G and immunoglobulin M serum levels), function enzymes, and histological alterations in the liver of rats. Materials & Methods: Sixteen albino male rats at fifteen weeks were grouped into four groups, and administered with aluminum chloride at 35g/Kg of body weight for 8, 12 ...
