Hospital Physician January 2009 23 Hyponatremia represents an abnormal ratio of total body sodium to water and is commonly defined as a plasma sodium concentration less than 135 mEq/L (1 mEq/L = 1 mmol/L).1–7 Hyponatremia is the most common electrolyte abnormality in hospitalized patients, with mild hyponatremia (plasma sodium < 135 mEq/L) present in approximately 15% to 22% of patients, modera...

While a number of electrolytes play a role in the genesis of the transmembrane action potential (AP), the changes in the action potential most clearly related to arrhythmias are dependent to a large extent on K+. Potassium gradient is a major determinant of the magnitude of transmembrane resting potential (TRP), and secondarily the rate of rise (dV/dt) of phase 0, and consequently the speed of ...

Background. Prolonged obstructed labour is a major cause of maternal and perinatal morbidity and mortality especially in the developing countries of the world, where the incidence is high. These complications are partly attributed to the metabolic and electrolyte derangements that are often associated with this problem. It is, therefore, important to evaluate the metabolic and electrolyte chang...

A counter-electrode comprised of large-pore sized mesoporous carbon exhibits low charge transfer resistance in iodide/triiodide redox electrolyte, thus liquid and quasi-solid dye sensitized solar cells show 8.18% and 3.61% solar to electric energy conversion efficiency, respectively.

An analysis of the electronic properties of amorphous semiconductor–electrolyte junction is reported for thin (Dox < 20 nm) passive film grown on Nb in acidic electrolyte. It will be shown that the theory of amorphous semiconductor–electrolyte junction (a-SC/El) both in the low band-bending and high band-bending regime is able to explain the admittance data of a-Nb2O5/El interface in a large ra...

A STUDY of serum electrolyte bevels in the alcoholic was undertaken in view of the reports from Flink and his associates 1,2 of the frequent occurrence of low serum magnesium levels in the chronic alcoholic with delirium tremens, with the improvement of the tremor, handwriting, and hallucinations in these patients occurring with magnesium therapy. As other electrolyte changes were not documente...

Superconformal electrodeposition is explained based on a local growth velocity that increases with coverage of a catalytic species adsorbed on the copper-electrolyte interface. For dilute concentration of the catalyst precursor in the electrolyte, local coverage in fine features changes more due to interface area change than by accumulation from the electrolyte, yielding superconformal growth. ...

A byproduct of experience with the artificial kidney was the detection of reversible electrocardiographic "currents of injury" in patients with electrolyte imbalance. These changes occurred irrespective of anatomic alterations and resembled the changes of acute pericarditis or myocardial infarction. The electrolyte basis for the "current of injury" was established by the prompt abolition of the...

We report direct visualization of electrochemical lithiation and delithiation of Au anodes in a commercial LiPF6/EC/DEC electrolyte for lithium ion batteries using transmission electron microscopy (TEM). The inhomogeneous lithiation, lithium metal dendritic growth, electrolyte decomposition, and solid-electrolyte interface (SEI) formation are observed in situ. These results shed lights on strat...

in the presented research, heat transfer of a mobile electrolyte alkaline fuel cell (afc) (which the electrolyte has cooling role of system) has been considered. proper control volumes of system with specific qualification have been chosen. consequently, heat and mass transfer in control volumes have been assessed. considerations on them and contributed models lead to approve a double tube heat...
