Background: Nurses are the largest group of medical caregivers in the world. Having highly capable nurses in a healthcare system is directly associated with more favorable outcomes for patients. The rapid development of new medical procedures and equipment necessitates constantly developing new skills and competencies. Thus one of the effective means towards their efficient tra...

Oligopeptidase B (OpdB, E.C. 3.4.21.83) is a proteolytic enzyme that belongs to the prolyl oligopeptidase family (POP) of serine proteases [10, 24]. Initially discovered in E. coli, this enzyme was found in several gram-negative bacteria, spirochetes, [6, 24], and protozoa [5, 14], but not in higher eukaryotes, with the exception of some plants [6]. Although the physiological role of OpdB has n...

introduction climate change is a change in the statistical distribution of weather patterns when it lasts for an extended period of time. climate change may refer to a change in average weather conditions, or in the time variation of weather around long-term average conditions. climate change is caused by factors such as biotic processes, variations in solar radiation received by earth, plate t...

A new process for the production of nanostructured materials, hypersonic plasma particle deposition (HPPD), is experimentally investigated. In HPPD, vapor phase precursors are injected into a flowing plasma generated by a DC arc. The plasma undergoes a supersonic expansion into a deposition chamber, with the pressure dropping across the nozzle from &500 Torr to &2 Torr. Ultrafine particles nucl...
