Ultraviolet (UV) irradiation is a common disinfection option for water treatment in the developed world. There are few systems installed developing countries point-of-use treatment, but low-pressure mercury lamps currently used as UV source have number of sustainability issues including fragile envelope, lifetime approximately one year, and they contain mercury. light emitting diodes (LEDs) may offer solutions to many presented by current systems. LEDs small, efficient, long lifetimes, do...
The World Health Organization (WHO) and United Nations Children’s Fund (UNICEF), through the Joint Monitoring Programme (JMP), are responsible for global monitoring of Sustainable Development Goal (SDG) targets drinking water, sanitation hygiene (WASH). SDGs represent a fundamental shift in household WASH with new focus on service levels incorporation hygiene. This article reflects process establishing SDG baselines methods used to generate national, regional estimates indicators. JMP 2017...
Continued management of sanitation and hygiene services, post-intervention, is a global challenge, particularly in the school-setting. This situation threatens anticipated impacts school investments. To improve programming policies, increase effectiveness limited development resources, we seek to understand how why some schools have well-managed while others do not. Based on in-depth qualitative data from 16 case Meherpur, Bangladesh, employ fuzzy-set comparative analysis identify necessary...
Despite an increasing focus on school-based water, sanitation and hygiene (WASH) interventions in less-developed countries, we lack understanding of what combinations conditions are sufficient for their continued maintenance post-implementation. We use a novel method, qualitative comparative analysis, to determine pathways lead well-maintained school toilets, as indicator WASH services. Results from 15 case schools Belize reveal five sanitation, three poorly maintained Common the toilets...
Abstract The inclusion of water, sanitation and hygiene (WASH) in non-household settings the Sustainable Development Goals (SDGs) elicits need for data to track progress over time. This review focuses on schools health care facilities, seeks to: (1) assess availability SDG baseline ten case study countries; (2) evaluate extent which existing national allow monitoring against criteria; (3) identify opportunities improve quality monitoring. While none countries could provide all needed...
Bacteria identification can be a time-consuming process. Machine learning algorithms that use deep convolutional neural networks (CNNs) provide promising alternative. Here, we present based approach paired with Raman spectroscopy to rapidly and accurately detect the identity of bacteria class. We propose simple 4-layer CNN architecture 30-class isolate dataset for training testing. achieve an accuracy around 86% speeds close real-time. This optical/biological detection method is applications...
This is a proof-of-concept study for the development of field-deployable and low-cost PCR thermocycler (FLC-PCR) to perform Polymerase Chain Reaction (PCR) rapid detection environmental E. coli. Four efficient (77.1 W) peltier modules are used as central temperature control unit. One 250 W silicone heating pad lid. The PID (proportional-integral-derivative) algorithm thermocycles implemented by 8-bit, 16 MHz microcontroller (ATMEGA328P-PU). ybbW uidA genes from specific coli colonies were...
