Exergoeconomic and enviroeconomic evaluations of conventional solar still using PCM and electric heater powered by solar energy: an experimental study.

Solar stills are used in distant and arid areas to convert brackish or salty water into potable water fit for human use in a simple, affordable, and effective manner. Even when PCM materials are used, typical solar systems still have minimal production per day. In this study, experimental tests were carried out in order to increase the performance of a single-slope solar still combined with PCM material (paraffin wax) and a solar-powered electric heater.

International Spinal Cord Injury Biobank: A Biorepository and Resource for Translational Research.

Over the past few decades, tremendous advances have been made in our understanding of the biological changes underpinning the devastating impairment of traumatic spinal cord injury (SCI). Much of this scientific research has focused on animal models of SCI, and comparatively little has been done in human SCI, largely because biospecimens from human SCI patients are not readily available. This paucity of scientific enquiry in human SCI represents an important void in the spectrum of translational research, as biological differences between animal models and the human condition need to be considered in the pre-clinical development of therapeutic approaches.
