3-2-3-1-Conventional Culture Method (Marks 1972): The infected lesions of the tuberculin positive reactors were collected and placed in to a sterile mortar containing sterile sand. The fat was removed and the suspected parts were cut into minute pieces. Then 2 ml of distilled water added to the mixture‚ homogenized and crushed well until the suspension was obtained. Then 2 ml of H2So4 acid 4% added to the mixture then incubated the mixture at 37 0C for 1/2 h. The mixture was diluted with

suspension of the powdered ore is made with water. To it‚ collectors and froth stabilizers are added. Collectors (e. g.‚ pine oils‚ fatty acids‚ xanthates‚ etc.) enhance non-wettability of the mineral particles and froth stabilizers (e. g.‚ cresols‚ aniline) stabilize the froth. The mineral particles become wet by oils while the gangue particles by water. A rotating paddle agitates the mixture and draws air in it. As a result‚ froth is formed which carries the mineral particles. The froth is light and

Benzene is a special case of conjugation that leads to an especially stable bonding arrangement. The benzene ring consists of six sp2 hybridized carbon atoms in a regular hexagon. Each carbon forms two σ-bonds with adjacent carbons‚ and a third σ-bond with a hydrogen atom. The 2p orbital on each atom is available for π-bonding. Interaction between the p orbitals on the six carbon atoms forms a conjugated system of π-electrons. Molecules with this bonding arrangement are called aromatic molecules

PBDEs were typically produced commercially at three different levels of bromination; nominally penta-‚ octa- and deca-BDE. The deca-PBDE formulation made up 83.3% of the 2001 PBDE global market demand‚ followed by penta- 11.1%‚ and octa- 5.6 %( LaA Guardia et al 2006). While PBDE’s are shown to be harmful in that they are bioaccumulative
