Foreign body multinucleated giant cells (FBGCs) and osteoclasts share several characteristics, like a common myeloid precursor cell, multinuclearity, expression of tartrate-resistant acid phosphatase (TRAcP) and dendritic cell-specific transmembrane protein (DC-STAMP). However, there is an important difference: osteoclasts form and reside in the vicinity of bone, while FBGCs form only under pat...

This study was designed to explore the relationship between deterioration of sea cucumbers and intestinal flora’s diversity change during preservation using 16S rRNA gene sequencing. We show that body wall cucumber develops white spots on day 4, epidermis dissolves 7. The distinctive OTUs remain relatively low four days storage but increase potential gut microbiota biomarkers are Psychrobacter-...

ibn sina characterizes sidiqin argument as an argument by means of which the existence of necessary being is proved just on the basis of reflecting on the nature of being. he claims that his versions of the argument satisfy the criterion, really. mulla sadra, however, argues first that ibn sina’s arguments are not, properly speaking, based on reflecting on the nature of being, and second that t...

In this study, synthesis of copper nanoparticles and effect of the reaction conditions on the particle size were investigated. The copper nanoparticles were synthesized and stabilized in a narrow temperature range in the presence of polyvinylpyrrolidone under nitrogen atmosphere. Reaction temperature and concentration ratio of the reducing agent to the precursor (R/P) as two main conditions i...

A gas kick simulation model for deep-water horizontal well with diesel-based drilling fluid is presented in this paper. This model is mainly based on the mass, momentum, and energy conservation equations. The unique aspect of this model is the fluid-gas coupling and the change of mud properties after the gas influx from the formation. The simulation results show that the gas in an annulus disso...

In conventional wire electrical discharge machining (WEDM), WC-Co machined pieces can stay for hours in the worktank. pH range of dielectric Co actively dissolves and thus corrosion occur affecting mechanical properties lifetime those pieces. This study demonstrates how applying cathodic polarization through implementation auxiliary electrodes work zone helps reducing in-depth propagation attac...

One of the important challenges in geological storage of CO2 is predicting, monitoring, and managing the risk of leakage from natural and artificial pathways such as fractures, faults, and abandoned wells. The risk of leakage arises from the buoyancy of free-phase mobile CO2 (gas or supercritical fluid). When CO2 dissolves into formation brine, or is trapped as residual phase, buoyancy forces a...
