Treatment of Manganese in West Boylston Drinking Water

This project focused on the treatment of manganese in West Boylston Drinking water using polyphosphate. Laboratory experiments were conducted using E-pure water with added manganese, iron, and phosphate. West Boylston raw water was also tested with the addition of the polyphosphate chemical. Results for the experiments conducted under the current time frame showed that the polyphosphate was not working. A new hypothesis was developed as to why this was so. Other ions may be competing for the polyphosphate and the reactions times may need to be much longer to see the results of oxidation. Future work is needed

Water Conservation in Windhoek Schools

The goal of this project was to provide the Windhoek, Namibia Department of Infrastructure, Water and Technical Services with a set of recommendations that would help to reduce water consumption within the City's schools. Through our research we found the following sources of inefficiency: faulty infrastructure, vandalism, insufficient maintenance, inefficient use, and lack of water awareness and conservation education. Our recommendations include infrastructure improvements, maintenance expansion, vandalism prevention methods, water saving devices, and educational programs for both learners and administrators

The Ambivalent Role of Religion for Sustainable Development: A Review of the Empirical Evidence

Until recently, academia has largely neglected the impact of religion on sustainable development. However, empirical studies have shown that religion remains important in many societies and that its importance has been increasing since the beginning of the new millennium. This paper reviews the empirical quantitative literature on the effect of religion on development from the last decade. We start by disaggregating the concepts of religion and sustainable development into four religious and three developmental dimensions and proposing a framework to identify causal mechanisms. Numerous mechanisms are possible, and this complexity explains why only a few uncontested findings exist. Religion is ambivalent vis-à-vis development: although religious dimensions exert a positive influence on physical and mental health as well as on general well-being, scholars have found a negative relationship between religious dimensions and both income and gender equality. Studies agree that the dominance of one religious group together with parallel ethnic and religious cleavages increases the risk of conflict, while studies on the pro-peace effects of religious factors are largely missing. Methodological challenges relate to the availability of fine-grained data, especially for non-Western countries, and the use of concepts and definitions. Most importantly, the study of religion and development requires methods that allow for causal inference

Oxygen targets and 6-month outcome after out of hospital cardiac arrest: a pre-planned sub-analysis of the targeted hypothermia versus targeted normothermia after Out-of-Hospital Cardiac Arrest (TTM2) trial

International audienceAbstract Background Optimal oxygen targets in patients resuscitated after cardiac arrest are uncertain. The primary aim of this study was to describe the values of partial pressure of oxygen values (PaO 2 ) and the episodes of hypoxemia and hyperoxemia occurring within the first 72 h of mechanical ventilation in out of hospital cardiac arrest (OHCA) patients. The secondary aim was to evaluate the association of PaO 2 with patients’ outcome. Methods Preplanned secondary analysis of the targeted hypothermia versus targeted normothermia after OHCA (TTM2) trial. Arterial blood gases values were collected from randomization every 4 h for the first 32 h, and then, every 8 h until day 3. Hypoxemia was defined as PaO 2  300 mmHg. Mortality and poor neurological outcome (defined according to modified Rankin scale) were collected at 6 months. Results 1418 patients were included in the analysis. The mean age was 64 ± 14 years, and 292 patients (20.6%) were female. 24.9% of patients had at least one episode of hypoxemia, and 7.6% of patients had at least one episode of severe hyperoxemia. Both hypoxemia and hyperoxemia were independently associated with 6-month mortality, but not with poor neurological outcome. The best cutoff point associated with 6-month mortality for hypoxemia was 69 mmHg (Risk Ratio, RR = 1.009, 95% CI 0.93–1.09), and for hyperoxemia was 195 mmHg (RR = 1.006, 95% CI 0.95–1.06). The time exposure, i.e., the area under the curve (PaO 2 -AUC), for hyperoxemia was significantly associated with mortality ( p = 0.003). Conclusions In OHCA patients, both hypoxemia and hyperoxemia are associated with 6-months mortality, with an effect mediated by the timing exposure to high values of oxygen. Precise titration of oxygen levels should be considered in this group of patients. Trial registration : clinicaltrials.gov NCT02908308 , Registered September 20, 2016
