UNLABELLED The World Health Organization's 2004 Global and Regional Burden of Disease Report estimates that acute respiratory infections from indoor air pollution (pollution from burning wood, animal dung, and other bio-fuels) kill a million children annually in developing countries, inflicting a particularly heavy toll on poor families in South Asia and Africa. This paper reports on an experim...

The sol-gel process is a wet-chemical technique (chemical solution deposition), which has been widely used in the fields of materials science, ceramic engineering, and especially in the preparation of photocatalysts. Volatile organic compounds (VOCs) are prevalent components of indoor air pollution. Among the approaches to remove VOCs from indoor air, photocatalytic oxidation (PCO) is regarded ...

The examination of water and other environmental sources for microbial pollution is a major public health undertaking. Currently, there are two accepted methods in use: the multiple-tube fermentation (MTF) and the membrane filtration (MF) tests. Both methods are designed to enumerate the secondary indicator group, total coliforms. Both tests suffer several inherent limitations, including a time...

The Geostationary Fourier Imaging Spectrometer (GeoFIS) is proposed as part of the European Geostationary Tropospheric Pollution Explorer (GeoTroPE) mission. For this mission, two instruments are considered: one covering the thermal infrared region (GeoFIS) and one covering the ultraviolet–visible and near-infrared regions (GeoSCIA). The geostationary orbit (GEO) provides indeed a unique opport...

Recent air pollution incidents in Chinese cities prompted this study, which makes use of air particulate monitoring information being submitted by volunteer-owned equipment to a public website. As an indicator of severe air pollution spikes, such as those seen in February 2014, the daily average readings for all monitoring locations were mapped and animated as a time series. Figure 1: China air...

This paper proposes an integrated ecological, economic and social model to assist sustainable rural development in villages in Bangladesh. In the model, renewable energy technologies (RETs) create income-generating activities for male landless and marginal farmers and for women from such households, while reducing environmental problems, like deforestation and indoor air pollution from cooking ...

BACKGROUND While any type of field-based research is challenging, building action-oriented, participatory research in resource-constrained settings can be even more so. OBJECTIVE In this article, we aim to examine and provide insights into some of the practical challenges that were faced during the course of a participatory project based in two non-notified slums in Bangalore, India, aiming t...

A knowledge-based system is presented that has been developed to be used as an advisor in the preliminary design stage of HVAC systems. It enables designers to configure and size HVAC equipment for different climatic conditions, in terms of building type, indoor requirements, outdoor and indoor air pollution. A new approach has been used in building the system, using a modified knowledge engine...

INDIAN PEDIATRICS 538 VOLUME 45__JULY 17, 2008 Pneumonia is now widely regarded as the dominant cause of child mortality in the developing world with over 150 million cases and almost 2.4 million deaths annually(1). Although there are remarkable advances in preventive strategies including nutrition interventions such as promotion of exclusive breastfeeding, environmental control such as reducti...
