Abstract:

The energy-loss effect of the projectile for direct inner-shell ionization cross sections by charged-particle impact has been examined. The relativistic and nonrelativistic calculations for K-shell ionization with and without the energy-loss effect are made in the plane-wave Born approximation and compared with the Brandt-Lapicki theory for the corrections of the relativistic and energy-loss effect. It is demonstrated that the Brandt-Lapicki method gives a good approximation to both relativistic and nonrelativistic cross sections, which implicitly take into account the energy-loss effect. Howe

Abstract:

The effect of propranolol (0.15 mg/kg body wt) on K+ fluxes was investigated in seven healthy males performing 8-min two-legged knee-extension exercise at two different powers. K+ concentration was measured in the femoral vein by a K(+)-selective electrode, and leg blood flow was measured by the dye-dilution technique. During control bouts, rates of change in femoral venous K+ concentration were 38 +/- 10 and 53 +/- 8 mumol.l–1.s-1 at onset of exercise (K+ efflux) and -14 +/- 3 and -34 +/- 3 mumol.l–1.s-1 at cessation of exercise (K+ reuptake) at low and high powers, respectively.

It has been suggested that increased K+ efflux during myocardial hypoxia and ischemia may result from efflux of intracellularly generated anions such as lactate and inorganic phosphate (Pi) as a mechanism of balancing transsarcolemmal charge movement. To investigate this hypothesis cellular K+ loss using 42K+ and K+-sensitive electrodes, intracellular potential, venous lactate and Pi, and tissue lactate and high-energy phosphates were measured in isolated arterially perfused rabbit interventricular septa during exposure to metabolic inhibitors, hypoxia, and ischemia.

Abstract:

The thioalkylating agent N-ethylmaleimide (NEM) causes ouabain-insensitive K loss from human red blood cells. This K loss is inhibited when intracellular Cl is replaced by another permeant anion or when loop diuretics are placed in the incubation medium after NEM exposure. In this report, we have tested the possibility that Cl replacement or loop diuretics not only influence the transport of K induced by NEM but also the interaction of NEM with its target sulfhydryl group. This possibility was examined by replacing intracellular Cl or exposing the cells to loop diuretics before NEM exposure, t

ABSTRACT Low intracellular K+ concentration ([K+]i) promotes apoptosis and blocking K+ loss prevents apoptosis, but the mechanism of action of low [K+]i remains unclear.

Low K+ concentration promotes NF-κB/DNA binding through direct effects on the interaction of NF-κB dimers with DNA.

Abstract:

Potassium (K+) is mainly absorbed by plants from the soil and is primarily transported within the plant through the xylem. Topping has been reported to cause efflux and loss of K+ in plants; however, its effect on the real-time flow rate and genotypes with varying K+ accumulation ability is still unknown. Therefore, we carried out a pot experiment containing sand culture using two tobacco cultivars EY1 (high K+ accumulating) and Y87 (low K+ accumulating). The results demonstrated the change of K+ flow direction from influx to efflux in the roots of both cultivars due to topping. The percentage

N-ethylmaleimide (NEM) treatment of steady-state Ehrlich cells induces a substantial net loss of cellular KCl and cell shrinkage. The majority of the initial K loss is Cl dependent.

The effect of NEM on H extrusion by cells in 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid (DIDS)-containing medium showed that only an insignificant part of the K loss could be attributed to an activation of a K-H exchange system. Consequently, NEM appears to activate a K-Cl cotransport, which causes cell shrin

Abstract:

Drop voltage and power loss at the distribution system of electricity power in the Kotamobagu Area are caused by several factors, a namely far distance of a place that is distributed by electricity power from the source, imbalance load, equipment age, the diameter of the conductor, a distance of powerhouse to the consumer is too far and connection point are caused for technical loss. If it keeps happening, it will decrease the reliability of the electric power system and the distributed quality of the electricity power as well as it can damage the equipment. Therefore, unbalanced loading shoul

Abstract:

ABSTRACTSulfur loss from the surface of MoS2(0001) is observed following the adsorption of methanol on MoS2 at 86 K and subsequent annealing of MoS2 near 300 K. This sulfur loss, at the MoS2 surface, leads to suppression of inverse photoemission features characteristic of the unoccupied states associated with MoS2. This sulfur loss is counteracted by further annealing to 350 K, as is evident in the temperature dependent sulfur to molybdenum integrated X-ray photoemission intensity ratios near 300 to 350 K. Upon further annealing to 350 K, inverse photoemission additionally indicates a reestabl

Abstract:

Elastic properties are important mechanical properties which are dependent on the structure, and the coupling of ferroelasticity with ferroelectricity and ferromagnetism is vital for the development of multiferroic metal–organic frameworks (MOFs). The elastic properties and energy loss related to the disorder–order ferroelectric transition in [NH4][Mg(HCOO)3] and [(CH3)2NH2][Mg(HCOO)3] were investigated using differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). The DSC curves of [NH4][Mg(HCOO)3] and [(CH3)2NH2][Mg(HCOO)3] exhibited anomalies near 256 K and 264 K, resp

Physiol Rev 83: 1269-1324, 2003; 10.1152/physrev.00011.2003.—In skeletal muscle, excitation may cause loss of K+, increased extracellular K+ ([K+]o), intracellular Na+ ([Na+]i), and depolarization. Since these events interfere with excitability, the processes of excitation can be self-limiting. During work, therefore, the impending loss of excitability has to be counterbalanced by prompt restoration of Na+-K+ gradients. Since this is the major function of the Na+-K+ pumps, it is crucial that their activity and capacity

Abstract:

N-ethylmaleimide (NEM) is a sulfhydryl-reacting agent known to stimulate chloride-dependent K transport in a variety of red cells. In high K sheep red cells, NEM-induced K movements are greater in magnitude in young cells compared with old cells. We hypothesized that human red cells might respond to NEM like high K sheep red cells. To test this idea, cells of various age were exposed to 0.5 mM NEM. We found that, after a 4-h incubation, young cells lost 50% of cell K, compared with 10% K loss in older cells. K loss in all fractions was inhibited by chloride replacement or furosemide.

Abstract:

Using a computer-controlled inverted torsion pendulum at frequencies near 1 Hz, we determined the mechanical losses in a uniaxially fiber-reinforced composite. The composite comprised glass fibers in an epoxy-resin matrix. We studied three fiber contents: 0,41, and 49 vol.%. Three mechanical-loss peaks appeared: above 300 K, near 200 K, and near 130 K. They correspond closely to α, β, and γ peaks found previously in many polymers. We failed to see a mechanical-loss peak for either the glass or the glass-resin interface. Between 300 and 4 K, the torsion modulus increased in the resin by a facto

Abstract Context.—Conventional cytologic evaluation of bile duct brushings for neoplasia has high specificity but relatively low sensitivity. Objective.—The aim of this pilot study was to examine whether K-ras mutations and loss of heterozygosity for multiple microsatellite markers in bile duct brushings would contribute to the detection of malignancy in cases initially reported as “negative” or “atypical.” Design.—Bile duct brushing specimens with a negative or an atypical cytologic result (9 cases) had a benign result on the surgical pathology specimen, and 9 additional negative or atypical

Abstract. Scenario-based climate change modelling for equilibrium conditions was applied to a Regional Model of permafrost probability for the southern Yukon and northwestern British Columbia. Under a −1 K cooling scenario, permafrost area expands from 58% (present day) of the 490 000 km2 to 76%, whereas warming scenarios of +1 K, +2 K and +5 K decrease the terrain underlain by permafrost to 38%, 24% and 9% respectively. The morphology of permafrost gain/loss under these scenarios is controlled by the Surface Lapse Rate (SLR), which varies across the region below and above treeline. The SLR is
