Biphasic systems formed by mixing of two polymers or a polymer and a salt in water can be used for separation of cells, membranes, viruses, proteins, nucleic acids, and other biomolecules. The partitioning between the two phases is dependent on the surface properties and conformation of the materials, and also on the composition of the two-phase system. The mechanism of partitioning is, however, c

The use of computer-assisted instruction in medical education has increased steadily in the last decade with the availability of personal computers. Many computer-assisted instruction programs train the user to handle various forms of disease or injury. Our intent was to provide medical students with more experience in managing ophthalmological emergencies, and we therefore designed a computerized

The eFundi learning management system as communication and relationship building instrument. Learning management systems (LMSs) are used by universities to support learning and teaching. Two-way communication and strong relationships can contribute to successful learning, however, LMSs are not generally viewed as an instrument to facilitate just that in an e-learning environment. The perceptions o

Background The coverage of prevention and treatment strategies for ischemic heart disease and stroke is very low in Ethiopia. In view of Ethiopia’s meager healthcare budget, it is important to identify the most cost-effective interventions for further scale-up. This paper’s objective is to assess cost-effectiveness of prevention and treatment of ischemic heart disease (IHD) and stroke in an Ethiop

People with physical disabilities (PD) suffer from consequences due to lack of physical activity and consequently, are at increased risk of chronic diseases. We aimed to evaluate the ability of a motorised assistive device for dynamic standing with weight-bearing in addition to standard state-of-the-art therapy to improve clinical outcome in a meta-analysis of available studies. A total of 11 stud

The biologically active pancreatic hormone peptide islet amyloid polypeptide (IAPP) regulates brain functions such as appetite and cognition. It also plays a role in clearance of amyloid beta (Aβ), a peptide implicated in the dementia disorder Alzheimer’s disease (AD). If IAPP becomes modified, it loses its biological activity and starts to aggregate. Such aggregations have been found in the AD br

New software vulnerabilities are published daily.Prioritizing vulnerabilities according to their relevance to the collection of software an organization uses is a costly and slow process.While recommender systems were earlier proposed to address this issue, they ignore the security of the vulnerability prioritization data.As a result, a malicious operator or a third party adversary can collect vul

The past few years have witnessed dramatic growth in the number of wirelessly connected devices, which will continue to increase in the future. Following this trend, the capacity of the wireless networks has been enhanced to provide high-quality service to tens of billions of devices. At the same time, in response to the network enhancement, each device unashamedly requests more and more throughpu
