Foundries employ green sand molds, which contain coal, silica sand, clay, water, and core binders. This represents one of the largest non-combustion users of coal. When the coal experiences high temperature during the metal casting process, it undergoes pyrolysis reactions and can generate significant amounts of volatile organic compounds. Some of the compounds are released as hazardous air pol...

Anticancer agents, such as cisplatin, stimulate nausea, vomiting, and behaviors indicative of malaise. Rats and mice do not possess a vomiting response, and, therefore, in these species, the ingestion of kaolin clay (a pica response) has been used as an index of malaise. In the rat, cisplatin-induced kaolin intake is inhibited by antiemetic treatments. In addition, cisplatin activates vagal aff...

This study investigates the feasibility of recycling various waste paving blocks as raw materials for concrete. The rate in Korea remains around 11%. Therefore, three types blocks, i.e., recycled clay-, granite-, and concrete block, were used partial replacements sand a mixture at 10%, 20%, 30% replacement ratios. According to Korean standards pavers building bricks, compressive strength, flexu...

The soybean cyst nematode (SCN), Heterodera glycines Ichinohe, is a severe pest of soybean, Glycine max (L.) Merr., in the United States. Nematode reproduction and the seed yield losses caused by this nematode are influenced by soil texture (3,5,6). Todd and Pearson (5) recovered higher numbers of SCN females and cysts from a sandy loam soil than from silty loams. Soybean yield also has been ne...

Abstract The effects of different absorbent types on changes in benzo[ a ]pyrene (BaP) and volatiles sesame oil during filtration processes were investigated using gas chromatography–mass spectrometry analysis. BaP content was greatly reduced after powdered activated carbons (activated carbon made from peat: PP, coconut shell: PC, wood: PW) comparison to granular GC, GW). also considerably when...
