In this work, existing and modified activity coefficient models are examined in order to assess their capabilities to describe the properties of aqueous solution droplets relevant in the atmosphere. Five different water-organicelectrolyte activity coefficient models were first selected from the literature. Only one of these models included organics and electrolytes which are common in atmospher...

BACKGROUND Two main theoretical models have been used to assess the impact of psychosocial work factors on blood pressure (BP): the demand-control model (DC) and the effort-reward imbalance (ERI) model. Little is known about their independent and combined effect. OBJECTIVE To examine the independent and combined effect of the DC and ERI models on ambulatory BP (ABP). METHOD Data were collec...

in this work we have applied the dense system equation of state (dseos) to electrolyte solutions. we have found that this equation of state can predict the density of electrolyte solutions very accurately. it has been tested for different electrolytes solutions at different temperatures and compositions. a hypothetical binary model has been applied to find the dependencies of parameters of this...

Because myocyte depolarization and repolarization depend on intra- and extracellular shifts in ion gradients, abnormal serum electrolyte levels can have profound effects on cardiac conduction and the electrocardiogram (EKG). Changes in extracellular potassium, calcium, and magnesium levels can change myocyte membrane potential gradients and alter the cardiac action potential. These changes can ...

It is shown using the mean field theory of Miklavic Marcelja that it should be possible for osmotic pressure due to the counterions associated with the two polyelectrolyte polymer brush coated surfaces (in the absence of excess salt) to support a reasonable load (i.e., about 105Pa)with the brushes held sufficiently far apart to prevent entanglement of polymers belonging to the two brushes, thus...

Title of Document: RELIABILITY EVALUATION OF LIQUID AND POLYMER ALUMINUM ELECTROLYTIC CAPACITORS 45BAnshul Shrivastava, Doctor of Philosophy (Ph.D.), 2014 Directed By: Professor Michael Pecht, Department of Mechanical Engineering Liquid aluminum electrolytic capacitors are known for their reliability problems. They are considered as the weakest link in the power electronics system. The liquid e...

The electrolyte is an indispensable component in all electrochemical energy storage and conversion devices with batteries being a prime example. While most research efforts have been pursued on the materials side, the progress for the electrolyte is slow due to the decomposition of salts and solvents at low potentials, not to mention their complicated interactions with the electrode materials. ...
