Gas stoves are now very common in all houses including urban and remote areas. The main power source for gas stoves are either LPG or biogas. Biogas is more cost effective compared to LPG. In both cases chemical energy stored in the fuel is converted into heat energy and this heat energy is used for cooking purpose. Explosive range of LPG is 1.8%-9.5% volume of gas in air. Biogas mainly contain...

For years, microGC analysis has been useful as a powerful tool for the fast and reliable analyses of natural gas and other gaseous matrices; but, it is yet to prove its capabilities for liquid samples. In this paper, we present a unique gasifying system for volatile liquid sample introduction in a microGC. The system has been tested with a wide range of different samples: liquefied gases (ethan...

BACKGROUND There is evidence that household air pollution is associated with poor health in China, and that this form of air pollution may even be more of a health concern in China than the much-publicized outdoor air pollution. However, there is little empirical evidence on the relationship between household air pollution and health in China based on nationally representative and longitudinal ...

BACKGROUND Household air pollution exposure is a major health risk, but validated interventions remain elusive. METHODS/DESIGN The Ghana Randomized Air Pollution and Health Study (GRAPHS) is a cluster-randomized trial that evaluates the efficacy of clean fuels (liquefied petroleum gas, or LPG) and efficient biomass cookstoves in the Brong-Ahafo region of central Ghana. We recruit pregnant wom...

Rising petroleum prices, an increasing threat to the environment from exhaust emissions, global warming and the threat of supply instabilities has led to the choice of inedible Mahua oil (MO) as one of the main alternative fuels to diesel oil in India. In the present work, MO was converted into biodiesel by transesterification using methanol and sodium hydroxide. The cost of Mahua oil biodiesel...

, we wish to notify the readers on the hazards caused by instant gas geysers. Two such cases presented to us last winter. Two young patients a 19 years old female admitted on 6th of February 2014, and 21 years old male admitted on 19th January, 2014 while taking a bath were found unconscious in the bathroom and presented to the emergency. These bathrooms were fitted with instant gas geysers wit...

The industrial production of dimethyl ether (DME) is now about 10,000 ton/year in Japan, and DME has been mainly used as an aerosol propellant. Recently, DME can be directly synthesized from water gas, carbon monoxide and hydrogen, by use of a new type catalyst dispersed in fluids. So, a large amount of DME will be supplied in future. Considering the molecular structure, the physical properties...

Abstract - One technology that is currently often used by humans the internet of things (IoT). With IoT technology, can easily overcome problems need, one which overcoming problem threat fire occurs due to gas leaks. To prevent these potential threats and dangerous risks, awareness needed. Humans need information in form timely warnings about leaks are as prevention risks threaten home security...

Berdasarkan dari kegiatan masyarakat ternyata plastik jenis LDPE (Low Density Polyethylene) ini paling banyak dijumpai di lingkungan bahkan sering menjadi sebagai sumber pencemar karena dapat mengganggu keseimbangan ekosistem. Biasanya terdapat pada kantong (kresek), sampah, tas belanja hingga bungkus makanan. Alat bekerja sederhana yaitu dimasukkan tungku pembakaran untuk mendapatkan proses pe...
