Drip fertigation has shown unquestionable benefits in recent decades compared to traditional farming fertilization practices. However, a fertilizer dissolved the irrigation water must be evenly distributed fertigated area. Irrigation system and characteristics operational management potentially affect uniformity of distribution. Advance time (AT), which is an intrinsic determinable characterist...

Inhibition of purified AMP-deaminase from chicken breast muscle by phosphate esters and inorganic phosphate has been investigated. When tested at a concentration of 3 mM, in the presence of 0.15 M potassium chloride, the order of effectiveness as inhibitors of deaminase activity was: 2,3diphosphoglyceric acid, 3-phosphoglyceric acid, 2-phosphoglyceric acid, 2-phosphoenolpyruvate, fructose 1,6di...

OBJECTIVES To examine the effect of intravesical administration of liposomes (LPs) on chemically induced bladder hyperactivity in the rat. It has been suggested that interstitial cystitis (IC) is associated with a dysfunctional or leaky epithelium. Thus, enhancement of epithelial barrier function might be useful in the treatment of IC. LPs are vesicles that are concentric phospholipid bilayers ...

Evolutionary structure searches predict two hitherto unknown phases of KCl that are the most stable in the pressure regime of 200-600 GPa. I41/amd-KCl, which has the lowest enthalpy between ∼200-350 GPa, can be thought of as being composed of two three-connected nets. This structure can be compared with that of the Cs-IV electride (Cs(+)e(-)): the potassium ions assume the positions of the cesi...

In vitro chemotactic responses of infective third-stage larvae (L3) of Brugia pahangi to NaCl, Na2HPO4, KCl, K2HPO4, MgCl2 and CaCl2 were assessed. Compared to deionized water as a control, 200 mm NaCl and 100 mm Na2HPO4 significantly attracted L3 (P < 0.01 and P < 0.01), whereas L3 were likely to avoid 200 mm KCl and 100 mm K2HPO4 (P < 0.05 and P < 0.05). L3 showed no significant tendency to a...

ABSTRACT Soil microorganisms are of paramount importance for crop yield. This study aimed to evaluate the effect potassium chloride doses associated with two bioactivation sources on soybean yield and soil microbial activity. The experimental design was randomized blocks, arranged in a 5 x 2 factorial scheme, four replications, being first factor (0, 30, 60, 90 120 kg ha-1 K2O), using as source...

We report our investigations into the self-assembly of sodium oleate (NaOA) in the presence of a binding salt (triethylammonium chloride, Et(3)NHCl) simple salt (potassium chloride, KCl). Both salts promote the growth of long, wormlike micelles in NaOA solutions, thereby increasing the fluid viscosity. The significant difference with the Et(3)NHCl salt is that it also modifies the phase behavio...

While water uptake of aerosols exerts considerable impacts on climate, the effects of aerosol composition and potential interactions between species on hygroscopicity of atmospheric particles have not been fully characterized. The water uptake behaviors of potassium chloride and its internal mixtures with water soluble organic compounds (WSOCs) related to biomass burning aerosols including oxal...

Potassium contractures were induced in lobster muscle bundles under conditions which produced varying KCl fluxes into the fibers. The presence or absence of chloride fluxes during depolarization by high concentrations of potassium, had no effect on the tensions developed. The curve relating tension to the membrane potential had a typical sigmoid shape with an apparent "threshold" for tension at...
