As students come from increasingly diverse backgrounds, researchers have called for greater understanding of the relationships between students and their families/home communities to foster college success. Our systematic integrative literature review demonstrates that there is limited information in science,...

Bipolar disorder (BD) is a common disorder with high reoccurrence rate in general population. It is critical to have objective biomarkers to identify BD patients at an individual level. Neurocognitive signatures including affective Go/No-go task and Cambridge Gambling task...

Using standard and institutional mentorship models to implement SLMTA in Kenya.

BACKGROUND: Kenya is home to several high-performing internationally-accredited research laboratories, whilst most public sector laboratories have historically lacked functioning quality management systems. In 2010, Kenya enrolled an initial eight regional and four national laboratories into the Strengthening Laboratory Management...

Psychiatric advance directives, a possible way to overcome coercion and promote empowerment.

Frontiers in public health

PMID: 24809041
Front Public Health. 2014 Apr 29;2:37. doi: 10.3389/fpubh.2014.00037. eCollection 2014.

Psychiatric advance directives (ADs) allow an individual to state their preferences for future treatment at times when they may be unable to make considered decisions. There are differences in their form and legal value and the process associated with...

Antimicrob Resist Infect Control. 2014 Jul 15;3:22. doi: 10.1186/2047-2994-3-22. eCollection 2014.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is an important nosocomial pathogen but little is known about its circulation in hospitals in developing countries. We aimed to describe carriage of S.aureus amongst inpatients in a mid-sized Kenyan government hospital.METHODS: We determined...

We report observations of the first low-to-high ( L-H) confinement mode transitions in the National Spherical Torus Experiment. The H-mode energy confinement time increased over reference discharges transiently by 100-200%, as high as approximately 100 ms. This confinement time...

Enhanced energy confinement and performance in a low-recycling tokamak.

Physical review letters

Majeski R, Doerner R, Gray T, Kaita R, Maingi R, Mansfield D, Spaleta J, Soukhanovskii V, Timberlake J, Zakharov L.
PMID: 17026238
Phys Rev Lett. 2006 Aug 18;97(7):075002. doi: 10.1103/PhysRevLett.97.075002. Epub 2006 Aug 17.

Extensive lithium wall coatings and liquid lithium plasma-limiting surfaces reduce recycling, with dramatic improvements in Ohmic plasma discharges in the Current Drive Experiment-Upgrade. Global energy confinement times increase by up to 6 times. These results exceed confinement scalings such...

High speed infrared camera diagnostic for heat flux measurement in NSTX.

The Review of scientific instruments

The application of nonaxisymmetric magnetic fields is shown to destabilize edge-localized modes (ELMs) during otherwise ELM-free periods of discharges in the National Spherical Torus Experiment (NSTX). Profile analysis shows the applied fields increased the temperature and pressure gradients, decreasing...
