Coalescence of two kinds of pre-processed droplets is necessary to perform chemical and biological assays in droplet-based microfluidics. However, a robust technique to accomplish this does not exist. Here we present a microfluidic device to synchronize the reinjection of two different kinds of droplets and coalesce them, using hydrostatic pressure in conjunction with a conventional syringe pum...

Geothermal energy is a clean resource, which could significantly contribute to the reduction of greenhouse and other gas emissions by replacing fossil fuels for power generation. In many geothermal sites, resource contains substantial Non-Condensable Gases (NCGs: CO2 contaminants), whose can be limited developing plant schemes suitable complete reinjection. Organic Rankine or closed-loop cycles...

The uptake of indium-111 labelled neutrophils was examined in 30 patients with acute myocardial infarction by planar imaging and single photon emission computed tomography. The time from venepuncture to reinjection of the autologous labelled neutrophils was less than 2.5 hours and imaging was carried out 24 hours later. Twenty three patients had a positive uptake of neutrophils in the myocardiu...

Abstract Oil production is currently impossible without drilling wells, so millions of tons waste contaminated with oil, chlorides, and heavy metals are generated every year in Russia alone. This article presents the results a comparative life cycle assessment water-based drill cuttings management technologies applied Russia, including disposal, solidification, reinjection. Life was performed u...

The epinephrine store of the suprarenal glands remains unaltered in guinea pigs and rabbits which have been sensitized to ox serum, or subjected to varying degrees of anaphylactic shock by the reinjection of the foreign protein.

Abstract “Blue energy” could be produced by exploiting the large salinity gradient between geothermal fluids and freshwater through a SaltPower system. This study is an attempt to select most favorable chemicals avoid injectivity issues when diluted fluid resulting from system returned reservoir. Three synthetic chelating agents (oxalic acid, EDTA, EDDS) one natural (humic acid) were evaluated ...

A new concept, the multi level voltage/current reinjection is described in this paper. A voltage source converter is proposed, in which the multistep output voltage waveform is achieved by the reinjection of different DC voltage levels via the common neutral point of the converter bridges an 84-pulse voltage source converter (VSC), assembled by combining one twelve-pulse VSC, in conjunction wit...
