It was reported previously that coenzyme A contained pantothenic acid bound in such a manner as to make it unavailable in microbiological tests (1). A liberation of p;alanine on acid hydrolysis indicated early the presence of pantothenic acid, which was confirmed by chick assay (2). While the chick assay for pantothenic acid and the p-alanine assay by the yeast growth test yielded equivalent am...

Uncoupling of photophosphorylation was shown in chloroplasts from spinach which were iso­ lated in media containing pyrophosphate and thereafter suspended in salt-free solutions. The effective concentration of pyrophosphate to uncouple was determined by the addition of pyrophos­ phate to free thylakoid systems and shown to be dependent on the presence of the completely dissociated species which...

Global interest in securing a supply chain for critical minerals, including rare earth elements, is increasing accordance with the intense promotion of energy transition and electric vehicle industry trend de-sinicization. Australia major resource-rich country 6th largest (RE) reserves world operating Mount Weld mine, highest REE grade mine world. Although beneficiation plant, which performs cr...

Introduction Most patients undergoing mechanical ventilation (MV) in critical care units are liberated from the ventilator within a median of 7 days. Unfortunately, some patients experience difficulty in liberation from MV during their ICU stays and require extended time on MV. It has been estimated that 40% of the patient’s duration on the ventilator is spent weaning.[1] Moreover, although pat...

An acceptorless dehydrogenation of heterocycles catalyzed by frustrated Lewis pairs (FLPs) was developed. Oxidation with concomitant liberation of molecular hydrogen proceeded in high to excellent yields for N-protected indolines as well as four other substrate classes. The mechanism of this unprecedented FLP-catalyzed reaction was investigated by mechanistic studies, characterization of reacti...

High-voltage electrical pulses (HVEP) technology was applied in grinding of a magnetite ore as a comminution pretreatment. The effect of HVEP pretreatment on grindability, liberation and separation performance of a magnetite ore was investigated by a systematic experimental study. The results showed that the pretreatment of high-voltage electrical pulses created some intergranular microcracks i...

objective(s): in this work, electrospun nanofibers were explored as drug delivery vehicles using tetracycline as a model drug.  nanocomposite fibers including chitosan (cs)/poly (ethylene oxide) (peo) and antibiotic were successfully prepared using electrospinning. cs blended with peo considering a weight ratio of (90/10), and then, nanofibrous samples were successfully electrospun from their a...

Depending upon the psychotherapist's orientation and the client's goals, meditation has beenused as a clinical intervention for selfregulation, self-exploration, and/or self-liberation. Most of meditation research to date, examining its self-regulation and self-exploration effects, has been based on an examination of short-term meditators (six to eight weeks, twenty to forty minutes a day). How...

This paper contends that there has been a definitive and negative change in the trajectory of so-called Islamic feminism. This change has been effected in large part in the West , as part of the growing discourse of Euro-Islam, European Islam, indigenization of Islam, etc., a discourse that comes not from governments (though it is mirrored, applauded and rewarded by governments in the region) b...
