Acknowledgement / Funding Declaration We wish to acknowledge the support of the ARRA Framework Programs for Global Health Signature Innovations Initiative (R24 TW008798-01). We would also like to express our gratitude to the University of Virginia and University of Venda students and the community members who assisted in the data collection which informed(More)
The persistent poor access to safe drinking water in low-income regions necessitates the development of low-cost alternatives to available yet expensive water treatment technologies. To address this need, this research investigates the development of a biofilter using the seeds of Moringa oleifera (MO), an indigenous tree in many low-income countries. The(More)
Depression is a major and costly global health burden that affects millions of people. The current diagnostic screen for depression relies on subjective structured interviews, but there is growing interest in exploring objective methods that involve depression biomarkers. In the current paper we perform a systematic review of recent articles on depression(More)
Although the Region of Waterloo implements a waste recycling program as part of its compliance with the 2004 Ontario Waste Diversion Goal a large fraction of its municipal solid waste ends up in the landfill. Landfill waste disposal adversely impacts the environment through the release of air pollutants and greenhouse gases to the atmosphere, and through(More)
Diarrhea, the second leading cause of child morbidity and mortality, can have detrimental effects in the physical and cognitive development of children in developing countries. Health interventions (e.g., increased access to health services and safe water) designed to address this problem are difficult to implement in resource-limited settings. In this(More)
The objective of this article is to discuss a needed paradigm shift in disaster risk analysis to emphasize the role of the workforce in managing the recovery of interdependent infrastructure and economic systems. Much of the work that has been done on disaster risk analysis has focused primarily on preparedness and recovery strategies for disrupted(More)
Nitrates, phosphates, and many other anionic chemical species are among the most problematic and widespread contaminants in water sources. Currently, technologies for removing them in water involve biological and physico-chemical processes. In this study, we test the extent to which the cationic protein from Moringa Oleifera (MO) seeds can effectively(More)
The release into the environment of antimicrobial compounds from both human and agricultural sources is a growing global concern. The Grand River watershed, the largest mixed-use watershed in southern Ontario, receives runoff from intensive animal production as well as municipal wastewater effluents from a rapidly increasing human population. A survey of(More)
Illicit drug use is a perennial societal problem that has serious ramifications on the health and socioeconomic well-being of a society. Its identification and estimation in communities is difficult because of the privacy laws and doctor-patient confidentiality agreements, which may limit the availability of reports and data. Various analytical strategies(More)
The failure to remove tetracycline (TC) in most conventional wastewater treatment systems results in the discharge and accumulation of TC in the environment, which in turn, increases the potential for developing TC-resistance in naturally occurring microorganisms. Thus, there is a need to explore other processes that can enhance TC degradation during(More)
