The principle of operation of the porous radiant burner (PRB) is based on porous medium combustion (PMC) in which the combustion of fuel and air mixture takes place inside a matrix of open cavities in the presence of an inert solid surface. Since the porous matrix has high thermal conductivity and high emissivity, the contributions of conduction and radiation in the PMC are significant. In the ...

OBJECTIVES We studied respiratory problems among vendors exposed to cooking fumes in an open-air hawker center. Exposure to cooking fumes from either the use of fossil fuels or liquefied petroleum gas (LPG) has been shown to be associated with adverse respiratory health effects. METHODS We conducted a cross-sectional study among 67 food vendors exposed to cooking fumes as well as 18 merchandi...

A previous study suggested the usefulness of pericardial fluid (PCF) and bone marrow aspirate (BMA) for the postmortem analysis of ethanol. The present study reviewed forensic autopsy cases (n = 2,983), which included 683 cases with the following positive toxicological findings, to reassess ethanol distribution and to investigate other gaseous and volatile substances in blood, PCF and BMA. Toxi...

OBJECTIVE The objective of this study was to compare the pulmonary functions in healthy non-smoking women who used either biomass or liquified petroleum gas (LPG) as their sole cooking fuel. The effects of passive smoking, ventilation, over crowding and cooking index were also taken into account. METHODOLOGY The study was conducted over a period of two years from January 1994. One hundred hea...

It is feared that the increasing population of vehicles in the world and the depletion of fossil-based fuel reserves could render transportation and other activities that rely on fossil fuels unsustainable in the long term. Concerns over environmental pollution issues, the high cost of fossil-based fuels and the increasing demand for fossil fuels has led to the search for environmentally friend...

Jenis gas LPG (Liquefied Petroleum Gas) ukuran 3 kg hanya diperuntukkan bagi masyarakat miskin dan pelaku UKM, tetapi jenis ini juga dinikmati oleh yang mampu industry. Hal terjadi karena tidak adanya sistem pengawasan terkomputerisasi mengenai pendistribusian dilakukan agen pangkalan. Penelitian bertujuan untuk mengembangkan informasi di PT.P(Persero) Gorontalo berbasis web. Metode pengembanga...

Abstract The current study examines the gas sensing properties of fabricated material Al 3+ modified ZnO. was by using co-precipitation technique. Here, sodium hydroxide used as precipitating to precipitate zinc convert it finally into insitu doping method adapted doped aluminum through ZnO lattice. characterized means several characterization techniques. X-ray diffraction (XRD) instrument util...
