This study aims to evaluate the influence of start-up on polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) concentration in the stack flue gas of incinerators and its contributing PCDD/F emission. The PCDD/F emission of the first sample among three consecutive stack flue gas samples of five intermittent incinerators, which sampled at a stable combustion condition aft...

the aim of this study was to determine the inhibitory effects of feed ingredients on protease activities of argyrosomus regius larvae using in vitro techniques. a. regius larvae fed on a commercial feeding procedure were sampled thirteen times, during the sampling period (from 3 to 32 days after hatching (dah)). the differences observed in protease activities of meagre larvae during the samplin...

the effect of intracerebroventricular injections of prostaglandins e2 and f2a was studied on the rectal temperature of sheep. pge2 but not pgf2a at the same dose of 50mg elevated the 1h post-injection of rectal temperature. pge2 but not pgf2a at the same dose of 100mg increased 3.5 and 2h post-injection of rectal temperature, respectively. elavation of rectal temperature following pge2 and pgf2...

Hydrogen, as a suitable and clean energy carrier, has been long considered primary fuel or in combination with other conventional fuels such gasoline diesel. Since the density of hydrogen is very low, port fuel-injection configuration, engine’s volumetric efficiency reduces due to replacement by intake air. Therefore, direct in-cylinder injection (injection after valve closes) can be solution f...

The martensitic transformation and the solidification structures of Mn49.3Ni43.7Sn7.0 alloy ribbons prepared by melt-spinning were investigated by means of scanning electron microscopy, X-ray diffraction and differential scanning calorimetry. In those experiments special attention was given to melt spinning processing parameters such as the linear surface speed of the copper wheel rotating, the...

Pilot-fueling and nozzle-injection pressure are significant injection parameters, they have impacts on modern vehicles for enhancing the engine output, in addition to meeting rigorous tailpipe-exhaust emission standards. In this current work, influence of pilot-fueling nozzle-opening (NOP) performance tailpipe outcomes from a compression-ignition (CI) at higher varying load conditions was inves...

This study aims to evaluate the use of oxidation reduction potential (ORP) to regulate the injection of a small amount of oxygen into an anaerobic digester for reducing H2S concentration in biogas. The results confirm that micro-oxygen injection can be effective for controlling H2S formation during anaerobic digestion without disturbing the performance of the digester. Biogas production, compos...

Effects of 2-buten-4-olide (2-B4O), an endogenous satiety substance, on levels of plasma glucose, corticosterone, and catecholamines were examined in fed, conscious, and unrestrained rats. A vascular indwelling catheter was inserted into the right atrium of the animal from the jugular vein 1 wk before the experiment. Injection of 2-B4O and blood sampling were performed through the catheter in a...

Needle projection was measured from where the needle protruded from the plastic casing to the proximal edge of the needle lumen. Fluid jet velocity through the EAI at 21 C was determined by calculating the [distance moved by the plunger]/[injection time] [plunger cross-sectional area]/[needle lumen area]. Injection time is from start to finish of the plunger movement. n 1⁄4 3. *Mann-Whitney U t...
