Pressure ulcers (PUs) are a serious global health challenge, affecting large section of the population and putting immense pressure on healthcare systems. Sensor-based diagnostic tools monitoring systems have emerged as potential non-invasive solution to reduce occurrence new cases PUs promise significant reduction in treatment expenditure time. In this endeavour, present manuscript reviews adv...

[1] Recent gullies on Mars are suspected to be the result of liquid‐water‐bearing flows. A formation from wet flows has been challenged by studies invoking granular (dry) flows. Our study focuses on the sinuous shapes observed for some of the recent Martian gullies. Sinuous gullies are found in locations and slopes (of 10°–15°) similar to straight gullies, and they are therefore related to the ...

Introduction: Lichen dominated cryptoendolithic communities from the Dry Valleys of Antarctica have been the subject of much research over recent years owing to their potential as analogues of Martian lifeforms. This is primarily owing to the stress tolerant nature of the microorganisms, remarkable adaptive achievements and the similarities between the Antarctic Dry Valley ecosystems and condit...

To the surprise of many, studies of molecular mechanisms of touch transduction and analyses of epithelial Na+ transport have converged to define a new class of ion channel subunits. Based on the names of the first two identified subfamilies, the Caenorhabditis elegans degenerins and the vertebrate epithelial amiloride-sensitive Na+ channel, this ion channel class is called the DEG/ENaC superfam...

Introduction: The SNC meteorites and the Pathfinder and MER Rover data represent our only information on individual rocks on the Martian surface, and therefore our only glimpse into Martian igneous processes. Because of this limitation, terrestrial analogues would provide a wealth of additional information. Analogies to terrestrial rocks have been made for the meteorites and Pathfinder rock but...

The number of courses delivered online or supported using learning management systems continues to rise; both in size and number, it is used by more students and employees to gain new knowledge, learn skills and earn degrees. (1) In contrast to traditional methods of teaching that leave little trail behind, online learning has the potential to generate huge amounts of data about the students an...
