Engine efficiency and emissions depend on the fuel atomization dispersion. The dispersion heavily ambient pressure temperature. In this work, to study Diesel sprays in engine conditions, an electrically heated, constant-volume, pressurized vessel was designed manufactured. controlling electronics software were developed tested ensure safe precise operation. A commercial Bosch six-hole automotiv...

stachys lavandulifolia vahl is an herbaceous wild plant native to iran which is traditionally used in iranian folk medicine as a mild sedative tea for reducing anxiety and for treatment of gastrointestinal disorders. our previous study on ethyl acetate extract of s. lavandulifolia proved anti-anxiolytic activity and so the present study was designed to determine chemical components of this biol...

This article describes an accurate subPico flowmeter bifurcatedin to liquid and gas flowrates less than 1mol/s for both MEMS/NEMS and cryogenic technology applications. The MEMS/NEMS are described as either two Gauges (instrument), or quartz fluctuating forks, even if the liquid or gas flows through an element, as well as cryogenic technology consisting of arrays of e...

dispersive liquid-liquid microextraction method (dllme) combined with high-performance liquid chromatography-ultraviolet detection (hplc-uv) was used to determine thiamine (b1), nicotinamide (b3) and pyridoxine (b6) in sour cherry juice. this method was rapid, simple and sensitive. separation was accomplished using a c18 column. the optimum chromatographic conditions were found to be: mobile ph...

background and objectives: furfural (f) and hydroxymethyl furfural (hmf) are cyclic aldehydes, which are formed during the heat processing of foods. these chemical contaminants have received much attention due to their suspected health hazards and heat damage indicators. the aim of the present study was extraction and determination of f and hmf in baby-foods using dispersive liquid-liquid micro...
