Magnetohydrodynamic mixing was evaluated as an alternative to conventional high shear (HSM) in the preparation of carbomer hydrogels containing 1.22 wt% Carbopol® 980 NF. Neutralization dispersion (pH = 2.74) with triethanolamine (TEA) enabled adjust pH mixture and tune viscosity hydrogel. Using HSM, this approach limited 0.2 TEA 3.83) gel became too viscous recirculation flow dropped from 12 0...

We consider a PH/PH/1 queue in which a threshold policy determines the stage of the system. The arrival and service processes follow a Phase-Type (PH) distribution depending on the stage of the system. Each stage has both a lower and an upper threshold at which the stage of the system changes, and a new stage is chosen according to a prescribed distribution. The PH/PH/1 multi-threshold queue is...

background: induced abortion is not only a serious threat for women’s health, but also a controversial topic for its ethical and moral problems. we aimed to evaluate the relationship between neutralization techniques and attempting to commit abortion in married women with unintended pregnancy. methods: after in-depth interviews with some women who had attempted abortion, neutralization themes w...

sizing of paperboard has a distinctive position in packaging grade paperboard material. optimization of sizing by alum-rosin at neutral ph in 4 layered paperboard (330 g/m2) wereevaluated in this study to find the optimum ratio of alum- rosin loading in the process. fixed amount of 1% cationic dispersed rosin together with alum as a fixing agent at 5 different levels of 1, 1.5, 2, 3, and 4% (ba...

Every day, the amount of data generated by industrial applications based on Internet Things (IoT) grows. However, acquired as a result failures and communication disconnections in IoT devices might be noisy, inaccurate, incomplete. These issues have become crucial for production, quality, processing, analysis. The datasets used scope this study were collected real-time from water neutralizer sy...

Prothymosin alpha has previously been shown to be unfolded at neutral pH, thus belonging to a growing family of "natively unfolded" proteins. The structural properties and conformational stability of recombinant human prothymosin alpha were characterized at neutral and acidic pH by gel filtration, SAXS, circular dichroism, ANS fluorescence, (1)H NMR, and resistance to urea-induced unfolding. In...

CD4 functions as the cell-surface receptor for human immunodeficiency virus (HIV); however, the mechanism of virus entry into susceptible cells is unknown. To explore this question we used a human T lymphoblastic cell line (VB) expressing high levels of surface CD4. Neutralization of endosomal compartments (pH greater than 6.4) with lysosomotropic agents did not effectively inhibit HIV nucleoca...
