Mixed agricultural residue, inoculated with aerobic sulfide oxidizing microbial consortium, was used as biofilter media to study the removal efficiency (,R) of hydrogen sulfide (H2S). The effect of humidification and inlet H2S volume fraction on the performance of biofilter was also investigated. A 3.9 l bench scale biofilter was continuously operated to treat air containing H2S gas in the rang...

In order to determine the optimal conditions for humidification of inspired air through a tracbeostomy, tracheostomized dogs were allowed to breathe humidified air, the temperature of which was deliberately varied between 15C and 40°C. At 15°C, the air was saturated lower than 40% but was fully saturated at the other temperatures. Measurements of alveolar ventilation, functional residual capaci...

Humidification dehumidification desalination (HDH) is a promising technology for small-scale water production applications. There are several embodiments of this technology which have been investigated by researchers around the world. However, from a previous literature review [1], we have found no study which carried out a detailed thermodynamic analysis in order to improve and/or optimize the...

The scarcity of drinkable water supplies is becoming a serious and troubling challenge to long-term development. This issue emphasises the urgency implementing rapid desalination options. However, capital-intensive process that requires significant amount energy, since it now mostly powered by fossil fuels across globe, has potential leave carbon footprint. In this light, transitioning green en...

Abstract On Titan, methane is responsible for the complex prebiotic chemistry, global haze, most of cloud cover, and rainfall that models landscape. Its sources are located in liquid reservoirs at below surface, its sink photodissociation high altitude. Titan’s present past climates strongly depend on connection between surface atmosphere upper layers. Despite importance, very little informatio...
