A technique was developed to measure the total gaseous phosphorus content in biogas. The amount of air needed for a neutral to oxidising flame was mixed with the biogas. The gas mixture was burnt in a closed quartz burner and the combustion gasses were bubbled through a nitric acid solution. The phosphate content in the bubbling liquid was determined with sector field ICP-MS. The technique was ...

Environmental pollution consists of different types of pollutants in air, soil, and water. Due to the fact that plants can respond to environmental pollution, they can be used as bio-indicators for environmental monitoring. Air pollution in areas with oil and gas refineries nearby is an important problem. This study aims to survey the effects of gas refinery air pollutants on Conocarpus erectus...

Soo-Kwan Jang Choon-Sang Park Heung-Sik Tae (SID Member) Bhum Jae Shin (SID Member) Jeong Hyun Seo (SID Member) Eun-Young Jung Abstract — To investigate the influence of the gas condition, especially xenon (Xe) gas, on the wallvoltage variation in relation to the electric-field intensity during the address period, the wall voltages were measured under various Xe-gas content ranging from 11 to 2...

The chemical composition and in vitro gas production of some leguminous browse species were evaluated. Crude protein (CP) content was highest (P

In this paper, the modelling and control of the moisture content of the particles in a batch Fluidised bed dryer are studied. First, a lumped mechanistic model is developed to describe the heat and mass transfer between solid, gas and bubble phases and experimental validation shows that the model can be used to predict the particle moisture content and temperature profiles during the drying pro...

Hα+[NII] imaging observations of 369 late-type (spiral) galaxies in the Virgo cluster and in the Coma/A1367 supercluster are analyzed, covering 3 rich nearby clusters (A1367, Coma and Virgo) and nearly isolated galaxies in the Great-Wall. They constitute an optically selected sample (mp < 16.0) observed with ∼ 60% completeness. These observations provide us with the current (T < 10 7 yrs) star ...

The aim of this study was to determine possible differences between first cut and second cut forage of Birjand ecotype of Kochia scoparia for chemical composition and fermentability, and to evaluate the changes may be induced by N fertilization in chemical composition, fermentability, and utilizable crude protein (uCP) supply at the duodenum of dairy cows of Sabzevar ecotype of Kochia....

Zipeprol and dextromethorphan are abused together by young people in Korea to obtain a stronger hallucinogenic effect. Because large amounts of these drugs are taken for this reason, nine fatal poisonings due to zipeprol and dextromethorphan have been reported since 1993. In this paper, the concentration of drugs in the postmortem blood and gastric contents of these victims is examined. The det...

The paper presents the using of amperometric sensors in measurements of the oxygen content in the organic solutions such as beer. The resulted data compared with spectrophotometric data.
