the objective of this study was to assess the potential of cadmium sulfide nanoparticles loaded onto activated carbon (cdsn-ac) for the removal of sunset yellow (sy) dye from aqueous solution. adsorption studies were conducted in a batch mode varying solution ph, contact time, initial dye concentration, cdsn-ac dose. in order to investigate the efficiency of sy adsorption on cdsn-ac, pseudo-fir...

The surface chemistry of a commercial AC (AC(0)) was selectively modified, without changing significantly its textural properties, by chemical oxidation with HNO(3) (AC(HNO3)) and O(2) (AC(O2)), and thermal treatments under H(2) (AC(H2)) or N(2) (AC(N2)) flow. The effect of modified AC on anaerobic chemical dye reduction was assayed with sulphide at different pH values 5, 7 and 9. Four dyes wer...

CONTEXT Oral activated charcoal (AC) for toxin absorption should be applied as soon as possible. Extra-hospital AC-application on site by medical laypersons with pre-emptive obtained AC may save time, but may be inferior to AC-application by medical professionals. OBJECTIVE 1) Availability and incidence of pre-emptive stockpiling of AC on site in the German region Bavaria 2) time saved by AC-...

In this study, Mesobuthus gibbosus and Mesobuthus eupeus eupeus venom samples were compared for lethality, in vivo effects and proteins. Neutralization capacity of monovalent Androctonus crassicauda antivenom (RSHA anti-Ac) was tested against the lethal effects of the venoms.Venom was obtained from mature scorpions by electrical stimulation of the telson. The lethality of the venom and potency ...

This paper presents novel concept of a multiple converter. It works in three modesAC-AC converter voltage regulator, AC-AC converter frequency changer and AC-DC converter. All three modes work simultaneously. AC-AC converter mode of operation alters low input frequency to high output frequency across the load. AC-DC converter mode of operates with variable amplitude across load. This concept is...

We discovered structurally novel human calcium-sensing receptor (CaSR) allosteric agonists and compared their pharmacology to phenylalkylamine calcimimetics. 1-Benzothiazol-2-yl-1-(2,4-dimethyl-phenyl)-ethanol (AC-265347) activated CaSR signaling in cellular proliferation and phosphatidylinositol (PI) hydrolysis assays with potencies of 30 and 10 nM, respectively. (S)-1-Benzothiazol-2-yl-1-(2,4...

A novel single-phase pulsewidth modulation (PWM) direct ac-ac converter based on two-level nondifferential dual-buck ac chopper legs with inverting and noninverting operations is first proposed in this article. It has the ability to resolve both voltage sag swell problems at same time when used as distributed flexible conditioner. Compared traditional converter, it much enhanced system reliabil...

We previously reported that acute agonist activation of G(i/o)-coupled receptors inhibits adenylate cyclase (AC) type VIII activity, whereas agonist withdrawal following chronic activation of these receptors induces AC-VIII superactivation. Three splice variants of AC-VIII have been identified, which are called AC-VIII-A, -B and -C (with AC-VIII-B missing the glycosylation domain and AC-VIII-C ...
