Chemical and biological warfare (CBW) agents pose unavoidable threat, both to soldiers and civilians.Exposure to such deadly agents amidst the CBW agents contaminated environment can be avoided bytaking proper protective measures. Respiratory protection i... see more

Several studies have proven the efficiency of gasification as a thermal process in terms of material decomposition and chemical energy. Synthetic gas (syngas) is a gasification product that can be used as an energy source. However, it needs to undergo tre... see more

Purifying processes on gas or liquid streams are often required to treat such large volumes of fluid. Particles in air suspension will range downwards from 100 ?m. Down to 20 ?m they will be visible to naked eye, while on down to 0,1...0,2 ?m they can be ... see more

The purpose of the study was to analyze the deposits in injectors with fuel mixture of 87 octane with percentages of anhydrous ethanol at 5 %, and 87 octane gasoline. The experimental phase was carried out in two ignition engine vehicles at a test he... see more

In this work, performance improvements are described for a low-power consumption non-dispersive infrared (NDIR) methane (CH4) gas sensor using customised optical thin film bandpass filters (BPFs) centered at 3300 nm. BPFs shape the spectral characteristic... see more

 Resumen Introducción: Las partículas en suspensión PM2.5 son capaces de penetrar profundamente en el pulmón y se componen de mezclas químicas complejas, incluyendo mutágenos y carcinógenos como los hidrocarburos aromáticos policíclicos (HAPs); la in... see more

Methanethiol is an important odorant from pig houses, but it can be difficult to measure due to low concentrations, high volatility and becauseit easily reacts to form dimethyl disulphide. A method was developedfor sampling and measuring methanethiol with... see more

Nowadays, the gold technique in gastric evaluations still is scintigraphy in spite of ionization radiation dose per patient undergoing this procedure. Gastro images with ultrasound technique are controversial, because the stomach is a hollow cavity filled... see more

An annular denuder/filter-pack sampling technique has been employed to get an insight of the formaldehyde partitioning between gas phase and particles (PM2.5) in México City using short time sampling periods. Formaldehyde was tra... see more
