Device Architecture for Visible and Near-Infrared Photodetectors Based on Two-Dimensional SnSe and MoS: A Review.

While band gap and absorption coefficients are intrinsic properties of a material and determine its spectral range, response time is mainly controlled by the architecture of the device and electron/hole mobility. Further, 2D-layered materials such as transition metal dichalogenides (TMDCs) possess inherent and intriguing properties such as a layer-dependent band gap and are envisaged as alternative materials to replace conventional silicon (Si) and indium gallium arsenide (InGaAs) infrared photodetectors. The most researched 2D material is graphene with a response time between 50 and 100 ps and a responsivity of <10 mA/W across all wavelengths.

Birth Intervals and Associated Factors among Women Attending Young Child Clinic in Yumbe Hospital, Uganda.

Introduction: Evidence suggests that both short and long birth intervals are associated with poor maternal and child health outcomes. However, current studies suggest that a number of births still occur at short intervals. The aim of this study was to document birth intervals and associated factors among women of reproductive age in rural Uganda.

Prevalence of diarrhoea and associated risk factors among children under five years old in Pader District, northern Uganda.

Background: Diarrhoea remains a major cause of morbidity and mortality in children under 5 years in sub-Saharan Africa. Of the three East African countries, Uganda has the worst mortality rate in children < 5 years, with 22% of these deaths attributed to diarrhoea. For proper planning and implementation of control, an understanding of the prevalence and determinants of the disease is crucial.

Spatio-Temporal Variation in the Concentration of Inhalable Particulate Matter (PM) in Uganda.

Long-term particulate matter (PM) measurements were conducted during the period January 2016 to September 2017 at three sites in Uganda (Mbarara, Kyebando, and Rubindi) representing a wide range of urbanization. Spatial, temporal and diurnal variations are assessed in this paper. Particulate matter (PM) samples were collected for 24-h periods on PTFE filters using a calibrated pump and analyzed gravimetrically to determine the average density.

Probiotic Enrichment and Reduction of Aflatoxins in a Traditional African Maize-Based Fermented Food.

Fermentation of food products can be used for the delivery of probiotic bacteria and means of food detoxification, provided that probiotics are able to grow, and toxins are reduced in raw materials with minimal effects on consumer acceptability. This study evaluated probiotic enrichment and detoxification of , a commonly consumed traditional fermented cereal beverage in Uganda, by the use of starter culture with the probiotic yoba 2012 and C106. Probiotic was produced by fermenting a suspension of ground maize grain at 30 °C for a period of 24 h, leading to a decrease of the pH value to ≤ 4.

Feasibility of A Novel On-Site Detection Method for Aflatoxin in Maize Flour from Markets and Selected Households in Kampala, Uganda.

In sub-Saharan Africa, there is a high demand for affordable and accessible methods for on-site detection of aflatoxins for appropriate food safety management. In this study, we validated an electrochemical immunosensor device by the on-site detection of 60 maize flour samples from six markets and 72 samples from households in Kampala. The immunosensor was successfully validated with a linear range from 0.

Family Members' Experiences With Bereavement in the Intensive Care Unit.

Background: Losing a loved one in the intensive care unit can be challenging for families. Providing bereavement support may assist in the grieving process.

Objective: To describe family members' experiences with bereavement after the death of a loved one in the intensive care unit.

Utilization of Solid Waste as a Substrate for Production of Oil from Oleaginous Microorganisms.

The overwhelming demand of oil and fats to meet the ever increasing needs for biofuel, cosmetics production, and other industrial purposes has enhanced a number of innovations in this industry. One such innovation is the use of microorganisms as alternative sources of oil and fats. Organic solid waste that is causing a big challenge of disposal worldwide is biodegradable and can be utilized as substrate for alternative oil production.

Challenges faced in rural hospitals: the experiences of nurse managers in Uganda.

Aim: The aim of this study was to understand nurse ward managers perceived challenges in the rural healthcare setting in Uganda.

Background: The health workforce, essential medicines and equipment and political unrest are the main factors affecting the international community in addressing the hefty disease burden in World Health Organization African regions. Nurse ward managers have an important role to play to mitigate these factors in health facilities in these regions through leadership, supervision and support for staff.

Nurse managers' experiences in continuous quality improvement in resource-poor healthcare settings.

Ensuring safe and quality care for patients in hospitals is an important part of a nurse manager's role. Continuous quality improvement has been identified as one approach that leads to the delivery of quality care services to patients and is widely used by nurse managers to improve patient care. Nurse managers' experiences in initiating continuous quality improvement activities in resource-poor healthcare settings remain largely unknown.
