1.1 Biology is the science of life. Properties of Life. Biology is the science that studies living organisms and how they interact with one another and their environment
Cross-flow filtration (CFF) also known as tangential flow filtration is not of recent origin. It began with the development of reverse osmosis (RO) more than three decades ago. Industrial RO processes include desalting of sea water and brackish water, and recovery and purification of some fermentation products. The cross-flow membrane filtration technique was next applied to the concentration and fractionation ofmacromolecules commonly recognized

Abstract: Several 13-alkyl substituted analogs of berberine and palmatine were found to be highly active against two types of Staphylococcus aureus(SI and S2)of different origin. The most active 13-hexylberberine was 8 times more active(against SI)and the same order active(against
In the previous lectures we have described particle motion as it would be seen by an observer standing still at a fixed origin. This type of motion is called absolute motion. In many situations of practical interest, we find ourselves forced to describe the motion of bodies while we are simultaneously moving with respect to a more basic reference. There are many examples were such situations occur. The absolute motion of a passenger inside an aircraft is best
1. In Anthropology some insights have come from observing simpler societies and then applying what we learn to our own society a. There are some things in our society that we take for granted that are of very recent origin:
Notes LECTURE Biochemistry 9.17.04 ATP is both a unit of energy currency in a cell and a building block of RNA. Why? It is believed that early in evolution there were very few molecules around. Many key pathways are ancient, and trace their origin to the early stages of evolution of life on Earth. Incidentally, such pathways are usually highly conserved in modern organisms. This is probably because once
Like all other foods of plant or animal origin, milk contains several indigenous enzymes which are constituents of the milk as secreted. The principal constituents of milk (lactose, lipids and proteins) can be modified by exogenous enzymes, added to induce specific changes. Exogenous en- zymes may also be used to analyse for certain constituents in milk. In addition, milk and most dairy products
