Summary Improving the rate and extent of faecal decomposition in basic forms sanitation such as pit latrines would benefit around 1.7 billion users worldwide, but to do so requires a major advance our understanding biology these systems. As critical first step, bacterial diversity composition was studied 30 T anzania V ietnam using pyrosequencing 16S rRNA genes, correlated with number intrinsic environmental factors pH , temperature, organic matter content/composition geographical factors....
The proportion of elderly people in big cities developing countries, including Vietnam, is rapidly increasing during the age rampant urbanization. This being followed by a sustained rise illnesses, especially mental health issues. objective this study was to analyze association between depression and factors associated with among elderly. In cross-sectional study, 299 living Hanoi, were approached for data collection. Self-reported 66.9% (32.8% mild, 30.4% moderate, 3.7% severe cases)....
Abstract The occurrence of pesticides in drinking water sources is concern for production companies as well the end users. However, it still unclear which are removed, and to what extent, widely used treatment methods such coagulation–flocculation. Pesticides possibly interact with colloidal particles by adsorption on flocs during In this study, removal four (aldrin, dieldrin, atrazine, bentazon) was observed jar test experiments distilled surface (Dijle river, Belgium), using aluminium...
Dewatering of faecal sludge (FS) is indispensable for adequate FS management. However, comprehensive knowledge lacking on dewatering performance. This study compared the performance from different countries and onsite sanitation technologies, to assess influential characteristics dewatering, compare with wastewater sludge. We collected 73 samples septic tanks, lined pit latrines, unlined latrines johkasou tanks in Uganda, Vietnam Japan, 18 Switzerland. Capillary suction time (CST) total...
Progress toward Sustainable Development Goals for global access to safe sanitation is lagging significantly. In this Feature, we propose that misleading terminology leads errors of categorization and hinders progress service provision in urban areas. Binary classifications such as "offsite/onsite" "sewered/nonsewered" do not capture the need "transport treatment" or complexity should be discarded. "Fecal sludge management" used only development context low- middle-income countries, implying...
OBJECTIVE. The objective of this study was to determine whether the installation equipment for diaper-changing, hand-washing, and food preparation that is specifically designed reduce transmission infectious agents would result in a decrease rate diarrheal illness among children their teachers child care centers. METHODS. Twenty-three pairs centers were matched on size star-rated license level. One member each pair randomly assigned an intervention group other control group. Intervention...
Economic evidence on sanitation supports decisions resource allocation and selection of efficient affordable interventions. This study presents the economic efficiency (costs versus benefits) interventions to better manage human excreta, from 47 field sites, covering six countries Southeast Asia (Cambodia, China, Indonesia, Lao PDR, Philippines Vietnam). Costs were estimated in each location, while benefits (improved health, avoided water pollution, reduced access time, recovery) using...
To meet the Millennium Development Goal for sanitation around 440,000 people will have to be provided with adequate every day during 2001–2015, and corresponding figure WHO/UNICEF target of “sanitation all” by 2025 is 480,000 per 2001–2025. The provision services such huge numbers necessitates action on an unprecedented scale. This made even more difficult general lack knowledge part professionals intended beneficiaries about which arrangement most appropriate under circumstances. A...
The importance of faecal sludge management is gaining recognition. However, methods are still lacking to reasonably estimate the quantities and qualities (Q&Q) that need be managed, which makes planning for implementing solutions quite difficult. objective this study was collect analyse Q&Q at a citywide scale, evaluate whether "SPA-DET" data (=> spatially analysable - demographic, environmental technical) could then used as predictors sludge. 60 field samples questionnaires from Hanoi 180...
Previous research on multimodal entity linking (MEL) has primarily employed contrastive learning as the primary objective. However, using rest of batch negative samples without careful consideration, these studies risk leveraging easy features and potentially overlook essential details that make entities unique. In this work, we propose JD-CCL (Jaccard Distance-based Conditional Contrastive Learning), a novel approach designed to enhance ability match models. leverages meta-information...
Sanitation service chains (SSC) in many cities low- and middle-income countries are complex comprise poorly managed on-site centralized technologies that emit greenhouse gases (GHG). In this study, we aimed to estimate the impact of GHG mitigation measures along SSCs account for interdependencies SSC components with respect emissions. Using an Hanoi, employed a mass balance approach, empirical emission equations, carbon footprint estimation model emissions by component at baseline four...
Background The well-known active chlorine compound chloramine T (CAT) with broad-spectrum antimicrobial activity is in common therapeutic use for leg ulcers purulent coatings; however, this treatment painful. tolerability of the less aggressive N-chlorotaurine (NCT), an endogenous also produced vivo by stimulated human granulocytes, could be superior. Objectives To assess and efficacy NCT cleaning coatings chronic comparison CAT. Methods In a double-blind, randomized phase IIb clinical study...
This paper represents a personalized context - aware mobile learning architecture for supporting student to learn English as foreign language in order prepare TOEFL test. It provides adaptive content different learners based on awareness. In our model, the includes location, time, manner well learner's knowledge. Through suggested topics test questions, will be supported meeting their demands Besides, this also describes CAMLES system prototype that allows learner materials anytime anywhere...
To evaluate granular activated carbon (GAC) adsorption using low-cost–high-performance materials for removal of pesticides and organic matter in potable water production, a pilot-scale upgrade the conventional treatment process was studied Cam Giang Water Treatment Plant, Hai Duong Province, Vietnam. The pilot system designed to test various schemes consisting series processes, such as coagulation/flocculation, horizontal sedimentation, rapid sand filtration, adsorption, three types GAC...
Abstract In many areas of the world, rainwater has been collected and consumed by people. Our research aims to assess use impact operation maintenance activities system on drinking water quality in rural where there is no access a public system. Through questionnaire, direct visits, interviews sampling at surveyed households (HHs), it was found that 100 98% HHs used for cooking, respectively. Nearly, 80% them were aware necessity frequent reservoir cleaning as well first-flush removal....
The postharvest maintenance quality of fruits is significant for industrial applications. present study was conducted to evaluate parameters and bioactive components seedless lime (Citrus latifolia) fruit during cold storage. Lime were packed in perforated polyethylene bags, which then put into a expanded polystyrene box, stored cool chamber, at 10°C. Quality including skin color, weight loss, total soluble solids (TSS), juice percentage, technological index, titratable acidity (TTA),...
Abstract For many decades in Vietnam, rainwater harvesting has been widely used as a nature-based solution rural areas, aiming at good-quality drinking water with low cost and little energy. Recently, for attracted much attention from the Vietnam government. Furthermore, despite its efforts, outcomes are not expected due to local barriers. This paper reviewed demonstration projects some specific areas of identification technical, economic, social barriers, further suggesting possible...
