In vitro studies with the organic extracts of diesel particles have suggested that hydrocarbons such as PAH may play a role in an inflammatory response, but these have been limited by the possible artifacts introduced in the particle collection and processing. In this study, we avoid these artifacts and use an activated carbon denuder to remove hydrocarbons from the exhaust stream to investigat...

The aim of this work is to investigate the influence of NO/SO2 on the emissions of N2O from diesel engine. A direct-injection diesel engine (model NF-19SK YANMAR) one cylinder was employed to test the emission. This engine works on fourstroke cycle and was operated at 2200 rpm by 25, 50, and 75% engine load. The experiment by three level sulfur content of fuel by adding DBDS into MDO and experi...

A low cost, battery-operated, portable, real-time aerosol analyzer is not available for monitoring diesel particulate matter (DPM) concentrations in underground mines. This study summarizes a field evaluation conducted at an underground limestone mine to evaluate the potential of the TSI AM 510 portable photometer (equipped with a Dorr-Oliver cyclone and 1.0-mum impactor) to qualitatively track...

In order to meet environmental norms, Indian fuel policy aims at producing ultra low sulphur diesel (ULSD) in near future. A catalyst for meeting such requirements has been developed and kinetics of this catalytic process is being looked into. In the present investigations, effect of mass transfer on kinetics of ultra deep hydrodesulphurization (UDHDS) to produce ULSD has been studied to determ...

Abstract An integrated set of neutron diagnostics developed for the deuterium operation Large Helical Device (LHD) has been revealing behavior energetic ions in three-dimensional plasmas, together with energetic-particle diagnostics. In order to obtain deeper understanding physics related LHD, development plasma that can provide energy distribution is now being accelerated. Recent advances D-D ...

This study presents an experimental and analytical investigation on the effects of using methyl ester linseed oil (MELO)-diesel blend B10, B20, B30 with hydrogen injection 5%, 10%, 15% in a VCR (Variable Compression Ratio) diesel engine, operated compression ratios (CRs) 15, 16, 17, 18 DFM (duel fuel mode). also gives emphasis optimized emissions CO, CO2, NO, smoke, when engine was MELO-diesel ...

Objective Australian mental health care remains hospital centric and fragmented; it is riddled with gaps and does little to promote recovery. Reform must be built on better knowledge of the shape of existing services. Mental health atlases are an essential part of this knowledge base, enabling comparison with other regions and jurisdictions, but must be based on a rigorous classification of ser...

To determine the mechanism of STM decline following brain damage, patients with left hemisphere damage and aphasia (LHD+), patients with left hemisphere damage without aphasia (LHD-), and persons with right hemisphere dysfunction (RHD) were examined. An auditory-verbal memory task, as well as a series of visual memory tasks, consisting of designs, objects and pictures, were used. Patients with ...
