Background: Peripheral arterial disease (PAD) is characterized by atherosclerotic blockages of the arteries supplying the lower extremities, which cause a progressive accumulation of ischemic injury to the skeletal muscles of the lower limbs. Despite revascularization treatment intervention some PAD patients require follow up secondary treatment due to a continued decline in limb function, ...

Predictive food microbiology currently first requires experimental data for growth on fresh produce and then fitting an empirical or semi-empirical model to the data, making extrapolation to other conditions (temperature, type of produce) difficult. Herein, we develop a mechanistic model for the growth of human pathogenic bacteria (Escherichia coli O157:H7 and Salmonella spp.) on spinach using ...

Gaseous exhaust of different industries contains dust particles of different chemical precipitates that are harmful for the environment. Electrostatic Precipitators are very often used in industries like power plant to filter their gaseous exhaust and to prevent the atmosphere to being polluted. Electrostatic Precipitators are very efficient in dust particle collection from the flue gas. ...

Hydrogen storage in a metal hydride bed, uses an intermetallic alloy that can absorb efficiently high amounts of hydrogen by chemical bonding resulting to metal hydrides. This alloy is capable of absorbing and desorbing hydrogen while maintaining its own structure. The heat, mass and momentum transfer in a metal-hydride reactor is mathematically described by energy, mass and momentum balance ...

Gallium nitride (GaN) and its related nitride alloys with special physical properties are in technical areas of high interest. The growing of gallium nitride boules on non-native sapphire or silicon carbide requires complicated mechanisms of defect reduction in the lattice structure. Thus the production of gallium nitride substrates is a challenge. Hydride Vapor Phase Epitaxy (HVPE) is a ...

The water storage reservoir at the WTP Noardburgum is used to even out demand and supply and ensure a stable drinking water production capacity. At the moment the rectangular reservoir has a single pipeline which serves as an inlet during the fill cycle and as an outlet during the draw cycle. This study aims to examine the current mixing characteristics of the reservoir and to investigate ...

In this paper describes an original method for indirect measurement of the vapor pressure and temperature in the keyhole in electron beam welding. This method is based on the determination of the concentration of chemical elements in the vapor above the welding zone. Taking into account these data model is built 2D diffusion processes with heat and mass transfer elements in the melt, which ...

This work concerns the performance of an oxidation catalyst used in a NOx storage and reduction system. The oxidation of NO is the main objective of this study, where the presence of CO and propene has also been taken into account. Experimental data has been determined on a monolithic oxidation catalyst mounted after a heavy duty diesel engine in a rig. The conversion of hydrocarbons is ...
