Major differences between Site Mixed Slurry (SMS) and Site Mixed Emulsion (SME) Explosives 1. SME is in fact a plant made product (emulsion matrix) which need only to be sensitized by entrapment of gas bubbles either by‚ chemical gassing or addition of substantial quantity of porous ammonium nitrate (AN) prills‚ to form explosive. 2. SMS is truly a Site Mixed Slurry explosive in the sense that all intermediate ingredients (nearly five) are brought to field in a specially designed Pump

ACID / BASE BUFFER SYSTEMS Abstract A buffer solution is a solution that contains both an acid and a salt containing the conjugate base / acid in sufficient concentrations so as to maintain a relatively constant pH when either acid or base is added. In this experiment a selection of buffer solutions (Bicarbonate/carbonic acid)‚ Lake water and distilled water were obtained to compare their buffering behaviours when mixed both with an acid and a base. The results showed buffering capacities for

The ultimate recommendation is to add an extremity MRI scanner to the facility to relieve some of the usage of the main MRI machine. Providing this relief benefits in many aspects. The addition will provide an opportunity to expand the sports medicine and orthopedics department. A premier department that is recognized as elite‚ but this is just one aspect of improvement. Other improvements include the inpatient length of stay. The inpatient

importance of education for employability‚ focusing on the development of not only skills but also practical experience. Then‚ in order to enhance competitive advantage for graduate employment‚ students need to develop employability skills in addition to the acquisition of subject-specific knowledge. Higher Education Institutes (HEIs) need to identify ways of incorporate this requirement. This paper will review the existing research findings‚ studies and practices of employability skills
