Abstract. Atmospheric mercury speciation is of paramount importance for understanding the behavior once it emitted into atmosphere as gaseous elemental (GEM), oxidized (GOM) and particulate-bound (PBM). GOM PBM can also be formed in atmosphere; their sampling most problematic step atmospheric speciation. with traps composed KCl sorbent materials trapping solutions are commonly used methods, alt...

The long-term corrosion behavior of three FeCrAl(Si) alloys has been investigated in two environments (K2CO3 and KCl+H2O) at 600 °C. FeCrAl alloy experienced breakaway oxidation both but displayed a higher rate KCl+H2O. FeCrAlSi retained the primary protection presence K2CO3 underwent considerably reduced rates, suggested to be an effect prevention internal formation non-continuous corundum-typ...

Na soja a fertilidade do solo é considerado um dos principais fatores responsáveis pela queda de produtividade grãos. Devido isso o presente trabalho teve como objetivo avaliar uso diferentes fertilizantes nos componentes produção e grãos cultivados no cerrado. O experimento foi conduzido na safra 2016-2017. delineamento utilizado blocos casualizados esquema em faixas com cinco repetições. trat...

The effect of various concentrations of CaCl2 and KCl on egg white proteins during isoelectric precipitation of ovomucin was investigated in this study. At low concentrations of CaCl2 (<50 mM), lysozyme was the major contaminant in the precipitated ovomucin, whereas ovalbumin was the predominant one at high concentrations (>or=100 mM). At 50 mM CaCl2 concentration, the concentrations of both ly...

The consumption of sodium in excessive amount may lead to heart disease, which is the first leading cause of death in the United States. Process cheese is one of the high salt containing milk products. The objective of this study was to evaluate and compare the effects of potassium chloride (KCl) and potassium based emulsifying salts as a salt (NaCl) replacer on the chemical and microbiological...

OBJECTIVE This study was performed to determine effects of different curing salts on the quality of salamis and to assess feasibility of using NaCl-alternative salts. METHODS Various types of curing salts (KCl or MgCl2) as well as NaCl (sun-dried or refined) were incorporated for processing of salamis. The proximate composition, fatty acids, nucleotide-related compounds, and free amino acids ...

Dahl showed that feeding KCl prevents the rise in blood pressure caused by a high NaCl diet in salt-sensitive Dahl "S" rats. Such S rats when normotensive on a low NaCl diet have a 2 to 3 times greater pressor response than Dahl "R" rats to intracerebroventricular hypertonic saline (600 mOsm/liter) or angiotensin II (AII) (500 ng). Does dietary KCl prevent NaCl hypertension in S rats partly by ...

The influence of KCl concentration on the contraction kinetics of skinned frog muscle fibers at 5-7 degrees C was studied at various calcium levels. The magnitude of the calcium-activated force decreased continuously as the KCl concentration of the bathing solution was increased from 0 to 280 mM. The shortening velocity at a given relative load was unaffected by the level of calcium activation ...

In cultured neurons dissociated from the spinal cord of fetal mouse, high concentrations of KCl (47 mM) increased choline acetyltransferase (CAT) activity up to 5.5-fold but suppressed acetylcholinesterase (AChE) activity to less than half the level of control cells. Veratridine (3 microM) also increased CAT activity 1.6-fold and suppressed AChE activity to the same level as that induced by hig...
