Lipids active in biological systems demonstrate a broad range of behavior in water, from hydrocarbons which are insoluble, to molecules such as bile salts that possess potent detergent properties and interact with water rather dynamically. The purpose of this paper is to describe some of the physical properties of lipids with respect to their inter— action with aqueous systems, and to classify ...

The modification experiment of Inner Mongolia Baiyinhua lignite by hot air at 200 ℃ for 1 h was carried out. Thestructural changes before and after thermal were analyzed infrared spectrum. Theresults show that the moisture oxygen content in are greatly reduced modification, carboncontent calorific value also increased to varying degrees. In process variousoxygen-containing functional groups dif...

Aromatic essential oils play a significant role in pharmaceuticals, food additives, cosmetics, and perfumery. Essential mostly comprise aliphatic hydrocarbons, monoterpenoids, sesquiterpenoids diterpenes. Plant extracts complex mixture of terpenes, terpenoids, phenol-derived aromatic components. Terpenes are class hydrocarbons with numerous health benefits. These biological functions oil compon...

H ighly trained search-and-rescue (SAR) dogs are indispensable members of urban SAR teams responding to a variety of natural and man-made disasters. A large-scale disaster could result in the release and mixing of dozens or even hundreds of chemical agents. Therefore, urban disaster sites should be considered potentially contaminated with many dangerous chemicals and substances. In a previous r...

Possible enhancement of biodegradation of petroleum hydrocarbons in agricultural soil after tank truck accident (~5000 mg/kg dry soil initial concentration) by bioaugmentation of diesel degrading Pseudomonas fluorescens strain and addition of abiotic additives (humates, zeolite) was studied in a 9-month pot experiment. The biodegradation process was followed by means of analytical parameters (h...
