Let $a, b, k,in K$ and $u, v in U(K)$. We show for any idempotent $ein K$, $(a 0|b 0)$ is e-clean iff $(a 0|u(vb + ka) 0)$ is e-clean and if $(a 0|b 0)$ is 0-clean, $(ua 0|u(vb + ka) 0)$ is too.

In this study, two hydrophilic polymers hydroxypropyl methyl cellulose and beta-cyclodextrin (?-CD) are used to synthesize highly responsive spongy polymeric matrices. Porous stimulus-responsive network was developed improve the solubility of acyclovir (ACV) at significant level. Grafting successfully carried out by free radical polymerization technique. Spongy matrices were characterized perce...

The importance of having a fast, accurate, and reusable track for detection has led to an increase investigation in the field biosensing. Optical biosensing using plasmonic nanoparticles, such as gold silver, introduces localized surface plasmon resonance (LSPR) sensors. LSPR biosensors are progressive their sensing precision limit. Also, possibility tune range by varying size shape particles m...

Pectin is an appealing material for biomedical applications because of its biocompatibility, bioactivity, biodegradability as well gelling and stabilizing properties. In this work, porous pectin cryogels, aerogels xerogels were prepared via freeze-drying, sc drying evaporative at 60 °C under low vacuum, respectively, starting from the same precursor, a hydrogel. The physico-chemical structural ...

let a; b; k 2 k and u ; v 2 u(k). we show for any idempotent e 2 k, ( a 0 b 0 ) is e-clean i ( a 0 u(vb + ka) 0 ) is e-clean and if ( a 0 b 0 ) is 0-clean, ( ua 0 u(vb + ka) 0 ) is too.

A new class of surfactants with glycerate headgroups, that form viscous lyotropic liquid crystalline phases in excess water, have been investigated for their potential to provide sustained release matrices for depot drug delivery. Oleyl glycerate and phytanyl glycerate were used as representative surfactants of this new class, and their behaviour compared with that of glyceryl monooleate (GMO)....

integrally skinned asymmetric membranes based on nanocompositepolyethersulfone were prepared by the phase separation process using the supercritical co2 as a nonsolvent for the polymer solution. in present study, the effects of temperature and nanoparticle on selectivity performance and permeability of gases has beeninvestigated. it is shown that the presence of silica nanoparticles not only di...

Various methods are available to formulate water soluble drugs into sustained release dosage forms by retarding the dissolution rate. One of the methods used to control drug release and thereby prolong therapeutic activity is to use hydrophilic and lipophilic polymers. In this study, the effects of various polymers such as hydroxypropyl methylcellulose (HPMC), ethylcellulose (EC) and sodium car...
