Analytical chemistry laboratory manual for the student of chemical engineering department include the most important types of chemical glassware with their nomenclature, Chemical Safety in the Laboratory Conduct and describes the experimental procedures with a brief theoretical background and chemical equations.

Nothing is more important to an organization than the health and safety of its workers. The managerial effectiveness of any health and safety program is judged on the basis of how well it prevents injuries and ill health. Chemical Safety in the Laboratory provides a proven approach to implementing and maintaining an effective chemical safety program for laboratories in hospital, industrial, and educational settings.

The maxillary molars differ in design from any of the teeth previously described. These teeth assist the mandibular molars in performing the mastication (grinding the food), also they support the muscles of mastication. They are the largest and strongest maxillary teeth. They have large crowns with four well-formed cusps; two buccal cusps and two lingual cusps. Also, they have three roots; two buccal and one lingual, the lingual root is the largest. The outlines and curvatures of all the maxillary molars are nearly similar.

Registers of 8086 Microprocessor
• In the CPU, registers are used store information temporarily. The
information can be one or two bytes of data, or the address of data.
• In 8088/8086 general-purpose registers can be accessed as either16-bit or

The mandibular second premolar most commonly has three cusps but can have two as well. The three-cusp variety has one large cusp on the buccal with two smaller lingual cusps. The mesiolingual cusp is twice the size of the distolingual cusp. The three-cusp type, is UNIQUE since it is the only premolar that has three triangular ridges (one per cusp), and these ridges do NOT join to form a transverse ridge.......
