THE INFLUENCE OF TRAFFIC FLOW FACTORS ON AUTOMOBILE EXHAUST EMISSIONS
"... The influence of traffic flow factors on automobile exhaust emissions ..."
Emission of Carcinogenic Components with Automobile Exhausts
"... Different sampling methods for mutagenic polynuclear aromatic hydrocarbons (PAH) are described. These methods involve either direct sampling of raw exhausts which prior to filtering are cooled in a condenser, or filter sampling of exhausts diluted in a tunnel. The relevance of gas-phase PAHs of samp ..."

TREES IN URBAN STREET CANYONS AND THEIR IMPACT ON THE DISPERSION OF AUTOMOBILE EXHAUSTS
"... The aim of the present study is to clarify the influence of trees on the dispersion of automobile exhausts in urban street canyons. For this purpose, measurements have been performed with a small scale wind tunnel model of an idealized, isolated street canyon with model trees placed along the canyon ..."

POLLUTION MONITORING AND CONTROLLING CAUSED BY AUTOMOBILE EXHAUST GASES USING ZIGBEE TECHNOLOGY
"... Steganography is derived from the Greek word steganographic which means covered writing. It is the science of secret communication. The goal of steganography is to hide the existence of the message from unauthorized party. The modern secure image steganography presents a task of transferring the emb ..."

the embedded information to the destination without being detected byGases emitted from automobile exhausts have been monitored and controlled using a gas sensor arrays. The information from the sensor array has been transmitted to a remote location by ZigBee wireless technology. Quantitative and qualitative
AIR POLLUTION BY ROADSIDE DUST AND AUTOMOBILE EXHAUST AT BUSY ROAD-CROSSINGS OF LAHORE
"... Background: Lahore is one of the most polluted metropolis of Pakistan and only a few studies have been conducted in this country so far, for the assessment of pollution levels prevalent in relation to the ever increasing roadside automobile traffic. This study was carried out to assess the roadside ..."

Method for Determining H2S04 in Automobile Exhaust
"... A relatively simple procedure for measuring H2SO4 in auto exhaust will be presented. The system is compatible with the Federal constant volume sampler (CVS unit). The time required to get sufficient sample for titration is 15-30 min. Values on sulfates in exhaust with a catalyst car and a noncatalys ..."

INVESTIGATING THE EFFECTS OF WELDING ON THE CORROSION TENDENCY OF AUTOMOBILE EXHAUST PIPES IN ACID/SALT SOLUTIONS
"... This paper discusses the effect of welding on the corrosion tendency of mild steel and galvanized steel samples in acidic and salty conditions, low thermal fluctuations and prevailing atmospheric situations. Corrosion rates based on weight losses were determined with the tensile strength of welded a ..."

of the various corrosive conditions were also observed. This goes a long way to proffer recommendations on the maintenance and processing of automobile exhaust pipes, which are common engineering components with similar material makeup as those of samples used in the investigation and exposed to similar
Selective stopped-flow injection spectrophotometric determination of palladium(II) in hydrogenation and automobile exhaust gas converter catalysts
, 2000
"... Abstract A stopped-flow injection spectrophotometric method is reported for the determination of palladium(II), using 2,2 -dipyridyl-2-pyridylhydrazone (DPPH) as a colour forming reagent. The absorbance of the Pd(II)-DPPH complex was monitored at 540 nm, at pH≈0.3. The various chemical and physical ..."

cases the sampling rate was 30 injections per hour. The method is very selective because the strongly acidic medium used prevented the formation of complexes of the reagent with other ions. The method was successfully applied to the determination of palladium in hydrogenation and automobile exhaust gas
