Convergence of diffusion with concentrating capacity

Journal of Mathematical Analysis and Applications, 1989
AbstractThe diffusion of electric charge on a thin-film dielectric is described by an initial-boundary-value problem for a parabolic partial differential equation on a planar region. Consider the situation where conductivity on a given subregion increases to large values and the corresponding limiting problem has the total capacitance of that subregion

Capacity of discrete molecular diffusion channels [PDF]

2011 IEEE International Symposium on Information Theory Proceedings, 2011
In diffusion-based molecular communications, messages can be conveyed via the variation in the concentration of molecules in the medium. In this paper, we intend to analyze the achievable capacity in transmission of information from one node to another in a diffusion channel. We observe that because of the molecular diffusion in the medium, the channel

Are there sex differences in the capillary blood volume and diffusing capacity response to exercise?

Journal of applied physiology, 2017
Previous work suggests that women may exhibit a greater respiratory limitation in exercise compared with height-matched men. Diffusion capacity (DlCO) increases with incremental exercise, and the smaller lungs of women may limit membrane diffusing ...

The inspiratory capacity/total lung capacity ratio as a predictor of survival in an emphysematous phenotype of chronic obstructive pulmonary disease. [PDF]

, 2015
BackgroundForced expiratory volume in 1 second (FEV1) grades severity of COPD and predicts survival. We hypothesize that the inspiratory capacity/total lung capacity (IC/TLC) ratio, a sensitive measure of static lung hyperinflation, may have a ...

HIV infection is an independent risk factor for decreased 6-minute walk test distance. [PDF]

, 2019
BackgroundAmbulatory function predicts morbidity and mortality and may be influenced by cardiopulmonary dysfunction. Persons living with HIV (PLWH) suffer from a high prevalence of cardiac and pulmonary comorbidities that may contribute to higher risk of

The effect of aging and cardiorespiratory fitness on the lung diffusing capacity response to exercise in healthy humans.

Journal of applied physiology, 2017
Aging is associated with deterioration in the structure and function of the pulmonary circulation. We characterized the lung diffusing capacity for carbon monoxide (DLCO), alveolar-capillary membrane conductance (DmCO), and pulmonary-capillary blood ...

Amiodarone-Induced Pulmonary Toxicity - A Frequently Missed Complication. [PDF]

, 2016
IntroductionAmiodarone is often used in the suppression of tachyarrhythmias. One of the more serious adverse effects includes amiodarone pulmonary toxicity (APT).

Priming by Chemokines Restricts Lateral Mobility of the Adhesion Receptor LFA-1 and Restores Adhesion to ICAM-1 Nano-Aggregates on Human Mature Dendritic Cells [PDF]

, 2014
LFA-1 is a leukocyte specific β2 integrin that plays a major role in regulating adhesion and migration of different immune cells. Recent data suggest that LFA-1 on mature dendritic cells (mDCs) may function as a chemokine-inducible anchor during homing ...

Innovation in Plant-Greenhouse Interactions and Crop Management [PDF]

, 2008
(Semi)-closed greenhouses allow for better control of climate conditions compared to conventional greenhouses. To make the high investments for such greenhouses economically feasible, substantial yield increases are necessary.

Quantitative CT analysis in patients with pulmonary emphysema: is lung function influenced by concomitant unspecific pulmonary fibrosis? [PDF]

, 2019
Purpose: Quantitative analysis of CT scans has proven to be a reproducible technique, which might help to understand the pathophysiology of chronic obstructive pulmonary disease (COPD) and combined pulmonary fibrosis and emphysema.
