1. PART 1 THE BASIC UNITS CÁC BÀI KHÓA CƠ BẢN UNIT 1: CHEMISTRY AND ITS BRANCHES Chemistry is the science of substances of their structure, their properties, and the reactions that change them into other substances. The study of chemistry may be divided into the following branches: General chemist[r]
Gas. A gas consists of individual chemical molecules dispersed in air, like oxygen, atnormal temperature and pressure. Some gases are flammable, explosive, and/or toxic. The presence of a gas may be difficult to detect if it has nocolor or odor, and does not[r]
This experiment was carried out to investigate the stabilizing influence organic amendments on soil reaction and micronutrient availability. Three different soil types (viz. acid, neutral and sodic soil) were considered for our experiment to represent soils of the whole country. Soils were incubated[r]
- When the butter has melted and is bubbling,add your eggs and move the pan around tospread them out evenly- When the omelette begins to cook and firmup, but still has a little raw egg on top,sprinkle over the Cheddar, if using (Isometimes grate mine directly on to theomelette)-[r]
Total recovery of fermentable sugar from lignocellulosic biomass has foremost problem for liquid biofuel production. Several pretreatment methods have been tried, however use of ionic liquids is one of promising method then others, but it also has less efficiency. Hence a method was developed for pr[r]
Big reserve of Ground water in the World: 0,6 % of total world fresh water compares with surface water only 0,02% Ground water has a small content of solid and organic matter, microorganism (coliforms and e coli) that more safely than surface water (river, lake, lagoon, rain).

Volcanic ejecta or lahar can serve as an inorganic support for the immobilization of invertase. Pampanga and Bicol lahar samples were pretreated by ignition at 550o C for 5 hrs followed by concentrated hydrochloric acid treatment, activated by reaction with aminopropyltriethoxysilane (APTS) and then[r]

Ultrafiltration membrane was used to treat the effluent from textile industries. Crossflow ultrafiltration using GN polymeric membrane was used to remove the dye from textile effluent. A synthetic textile effluent of Direct-15 dye was used. The study focused through the effect of feed concentration,[r]
