We are going to consider the forces exerted on a material. These can be external or internal. External forces come in two flavors: body forces(given per unit mass or volume) and surface forces(given per unit area). If we cut a body of material in equilibrium under a set of external forces along a plane as shown in fig. 1. and consider one side of it we draw two conclusions: 1 the equilibrium provided by the loads from the side taken out is provided by a set of forces that are distributed among the material particles adjacent to

Lead-in The news that a sheep in Scotland has been successfully cloned 1) got me wondering What good would it be to clone humans? What would I do with a clone of myself? Then 2) it hit me that I could have my clone go into work for me while went out hiking, biking, sking,etc.! really could be in two places at once

1. When you can measure what you are speaking about, and can express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowleage is of a meagre and unsatisfactory kind: It may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the stage of science.

Organisations looking to develop their business operations through the current volatile economic climates need to establish clear objectives as to how the various elements of the business need to perform to ensure continuing growth and viability. In order to achieve these objectives it is further imperative to have mechanisms in place to monitor performance and also to provide a process by which change can be implemented in those areas of activity which need strengthening. Total Quality

Quality is an essential feature that will lead the consumer to select or not any food product. With numerous food scares that have hit the food market in the UK and Europe (E. coli, BSE, genetically modified organisms-based products, dioxins in animal feed in Belgium)consumers have become much more aware

The detection and enumeration of microorganisms either in foods or on food contact surfaces forms an integral part of any quality control or quality assurance plan. Microbiological tests done on foods can be divided into two types:(a) quantitative or enumerative, in which a group of microorganisms in the sample are counted and the result is expressed as the number of the organisms present
