INTRODUCTION Treatment of severe hemorrhagic shock due to acute blood loss from traumatic injuries in a Jehovah's witness (JW) trauma patient is very challenging since hemostatic blood product resuscitation is limited by refusal of the transfusion of allogeneic blood products. CASE PRESENTATION We describe a multifaceted approach to the clinical care of a severely anemic JW trauma patient inc...

In this work it is analyzed the performance of an iron waste material as oxygen carrier for a chemical-looping combustion (CLC) system. CLC is a novel combustion technology with the benefit of inherent CO2 separation that can be used as a source of energy for the methane steam reforming process (SR). The tail gas from the PSA unit is used as fuel in the CLC system. The oxygen carrier behaviour ...

Oxygen Transfer in Oxide Heterostructures In article number 2101867, Zachary Corey, Quanxi Jia, Aiping Chen, and co-workers demonstrate that the growth of an oxide layer a suitable condition can lead to oxygen transfer from substrate film during growth. Such forms conductive surface contributes observed high carrier mobility.

Metals like Fe, Ca, Mn present in sewage sludge ash have been deposited on high surface -alumina with high mechanical resistance used as bed materials during sewage sludge fluidized bed combustion to produce low-cost CLC oxygen carriers. The produced oxygen carriers have been characterized using ICP-MS, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and surface area (BET) analysis....

The Mn-oxide/Nb:SrTiO3 photoelectrode for oxygen evolution reaction was investigated by in situ Mn K-edge XAFS spectroscopy under UV irradiation. The oxidization of the Mn oxide was observed via photoexcited carrier transfer, which results in the positive potential shift of the Mn oxide cocatalyst toward oxygen evolution reaction.

INTRODUCTION As air travel has become more commonplace in today's society, so too has air travel by oxygen-using individuals. Because there is little oversight or standardization of in-flight oxygen by the Federal Aviation Administration, individual airlines' policies and practices may vary greatly. On the premise that such variation may cause confusion by prospective air travelers, we undertoo...

To analyze the effects of nitrifying bacterial community structure on partial nitrification (PN) characteristics in a PN-immobilized carrier municipal wastewater under low-temperature shock, two carriers with different communities were investigated. The E1-immobilized contained high abundance ammonia-oxidizing bacteria (AOB; 38.59%), and E2-immobilized had low AOB 4.78%. results experiments dis...

ABSTRAOT Toadfish, Opsanus tau, L., were maintained in sea water equilibrated with gas mixtures containing a fixed proportion of oxygen and varying proportions of carbon monoxide. The swim-bladder was emptied by puncture, and, after an interval of 24 or 48 hours, the newly secreted gases were withdrawn and analyzed. Both carbon monoxide and oxygen are accumulated in the swim-bladder at tensions...
