in the present study, the microstructure and mechanical properties of the dissimilar welding betweenastm a335 low alloy steel and er309l austenitic stainless steel were investigated using the gastungsten arc welding process. the welding of dissimilar materials between astm a335 low alloy steeland er309l austenitic stainless steel was found to have a significant effect on the microstructure when...

cementing is an essential part of every drilling operation. protection of the wellbore from formation fluid invasion is one of the primary tasks of a cement job. failure in this task results in catastrophic events, such as blow outs. hence, in order to save the well and avoid risky and operationally difficult remedial cementing, slurry must be optimized to be resistant against gas migration phe...

background and objectives: the addition of plasticizers (mainly phthalates and adipates) makes plastic flexible and popular for packaging, storing and preserving food, water, and so on. the most widely used plasticizer in food contact applications is di-ethylhexyl phthalate (dehp) though being suspected to have carcinogenic and estrogenic properties. the aim of this study is application of magn...

In the context of virtual machines live migration, two strategies called “pre-copy” and “post-copy” have already been presented; but each of these strategies works well only in some circumstances. In this paper, we have a brief presentation of QAVNS and then introduce a new approach which is based on the concept of "informational object", assigning QAVNS-scheme-revision number, and observing th...

Introduction: Essure® device malposition is a rare, but clinically significant complication, for which management is idiosyncratic. This case report describes an unusual example of Essure® migration in order to clarify reasonable management options. Case Presentation: A 50-year old G4P2022 underwent hysteroscopi...

Objective(s): The study aimed to investigate the effects of resveratrol on colorectal cancer HCT116 cells, including cell viability, apoptosis, and migration, and the partial mechanisms focused on hedgehog/gli-1 signaling pathways. Materials and Methods: We chose the appropriate time and concentration of recombinant human Sonic hedgehog (Shh) stimulation by cell viability. The proportion of cel...

Forced migration has become a world-wide phenomenon in the past century, affecting increasing numbers of countries and people. It entails important challenges from a global health perspective. Leppold et al have critically discussed the Japanese interpretation of global responsibility for health in the context of forced migration. This commentary complements their analysis by outlining three pr...

Network society is an ever-changing robust system expanding new nods as long as they can communicate. Videos, as a source of information and communication, are one of the most strategic nods in this architecture. The present study is a scholarly attempt in investigating the effects of videos on facilitating the process of migration for the Iranian students. To this end, our case studies partici...
