Task D Orchid View Care Home Orchid View opened as a care home in West Sussex in 2009‚ providing care and nursing for up to 87 people who were elderly‚ frail‚ had nursing‚ or dementia care needs. The £3000-per month care home that was run by Southern Cross‚ closed in October 2011 following an investigation by the Care Quality Commission (CQC) that found it had failed to meet eight of its essential quality and safety standards. While it was open‚ Orchid view had a number of adult safeguarding alerts

1) Segementation(2*2 matrix) and Targeting Segmenting the Dominite market by end-use applications of cermaic tile and paint by large and small-to medium comapnies 2) Sales Organization changes: Dominite is currently trying to sell to both large and small companies. It is economical in the long run to sell to large customers directly and to small companies through a agents or distributors. In the future to sell and to service large customers Dominite should setup a key account program.

Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods Section 5220B‚ Section

Peter Debye and his Contributions to Chemistry Abstract Dutch physicist Peter Debye studied under Arnold Sommerfeld‚ and developed several approaches using induced dipole moments and x-ray diffraction to study molecular structures. In 1912 he exhibited the Debye equation for dipole moments‚ a method to determine bond angles and the degree of polarity of covalent bonds‚ which allows the spatial configuration of molecules to be deduced with far greater accuracy than had previously
