H ion was generated through two processes within a volume Csfree source. The density of molecule hydrogen gas will impact on the electron temperature within the primary discharge chamber that will influence the population of vibrational excited H2. Within the extraction region, the interaction between molecule hydrogen and H ion will is cause the dissociation of negative ion. To better understa...

The monitoring of intestinal oxygen saturation by means of a pulse oximeter is routinely applied in human medicine during surgery of the gastrointestinal tract to evaluate the disturbance of perfusion and assess tissue viability. To some extent, this technique has been applied in veterinary medicine. The purpose of this study was to test the technique in cattle and to describe the influence of ...

Power–to–gas technology gives the possibility to store excess power from renewable energy sources by converting electrical into gas such as eg. hydrogen. There is however a problem with accessibility of sites where pure hydrogen can be stored. Hence, idea blending methane and use underground mine excavations increase storage capacity, apart salt caverns. However, has strong capability diffuse t...

Here we demonstrate a novel concept of liquid-in-gas droplet microfluidics by using gas flow as the continuous phase for the production of liquid droplets. Within a specially configured co-flow microfluidic tubing device, a flow of liquid phase has been continuously dispersed into another outer stream of gas phase, producing discrete and monodisperse microdroplets. This process is robust and we...

A method for routine preparation of a solution of 133 Xe gas in saline from commercially available m Xe gas ampoules is described and evaluated. At room temperature and atmospheric pressure, about 25% of the mxe gas dissolves in saline. Xenon-133 binds to the syringe wall or may escape into the air when stored in sealed plastic syringes. Preparation immediately prior to use, short-term storage ...

The forward pick area of a distribution center is a cache of conveniently located products from which order pickers can quickly draw, but which must be replenished from bulk or reserve storage. The quantities stored forward determine the amount of work required to sustain the forward pick area. Two stocking strategies that are commonly used in industry are analyzed and compared with the optimal...

The supersonic wind tunnel facility SBR-50 at the University of Notre Dame was built in 2015 for experimental research related to shock wave (SW) interactions with obstacles and boundary layers (BL) as well combustion a plasma-based flow control. Currently, provides following range parameters test section area nozzle exit 76.2 × mm: Mach number M=2 4, total pressure p0= 1–4 bar, stagnation temp...

During forced vital capacity maneuvers in subjects with expiratory flow limitation, lung volume decreases during expiration both by air flowing out of the lung (i.e., exhaled volume) and by compression of gas within the thorax. As a result, a flow-volume loop generated by using exhaled volume is not representative of the actual flow-volume relationship. We present a novel method to take into ac...

Annular gas-liquid two phase flow is widely encountered in the nuclear industry. Various combinations of techniques have been employed in annular gas-liquid two phase flows to measure the flow parameters (e.g. liquid film thickness, gas volume fraction and the phase flow rates). One of the most useful techniques which has proven attractive for many multiphase flow applications is the electrical...
