Basic sanitation and hygiene can prevent roughly a million deaths a year. This study examines the rapid prototyping of a pilot school-based handwashing, safe water, and sanitation program in Chennai, India. Our content analysis identified challenges in the classroom (Localization; Curriculum...

This paper aims at assessing the return on investment and carbon mitigation potentials of five investment alternatives for the Cuban cement industry in a long-term horizon appraisal (15 years). Anticipated growing demand for cement, constrained supply and an urgent need for optimisation of...

There is a paucity of studies on natural gas-based energy production in Small Island Developing States (SIDS) even though technological improvements today are likely to make the application of natural gas more and more feasible. The development of natural gas in some of the regions of the...

In this study we report on the protocols adopted and the findings from a pilot study in northern Ghana involving 40 respondents wearing accelerometry devices for a week. We show how integrating energy expenditure data from wearable accelerometry devices with data on activity and time-use can...

Background: Maternal mortality remains a major health challenge facing developing countries, with pre-eclampsia accounting for up to 17% of maternal deaths. Diagnosis requires skilled health providers and devices that are appropriate for low-resource settings. This study presents the first...
