    Introduction In the design of engineering projects‚ one of the most important soil properties of interest to the soils engineer is permeability. To some degree‚ permeability will play a role in the design of almost any structure. For example‚ the durability of concrete is related to its permeability. In designs that make use of earthen materials (soils and rock‚ etc.) the permeability of these materials will usually be of great importance. Soils are permeable (water may flow through them) because they

    Bacteria Bacteria are microscopic organisms whose single cells have neither a membrane-enclosed nucleus nor other membrane-enclosed organelles like mitochondria and chloroplasts. Another group of microbes‚ the archaea‚ meet these criteria but are very different from the bacteria in other ways. In fact‚ there is considerable evidence that you are more closely related to the archaea than they are to the bacteria! Bacteria are living things that are neither plants nor animals‚ but belong to a group

    The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms‚ such as the unicellular bacteria and protozoa; others‚ such as nerve‚ liver‚ and muscle cells‚ are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas‚ which are 0.1 micrometer in diameter‚ to the egg yolks of ostriches‚ which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function‚ all cells

    Bacterial Energetics and Membranes Abstract The Mg2+/Ca2+ ATP synthase present in all bacterial membranes‚ particularly E. coli‚ couples ATP synthesis to the proton (H+) gradient produced by the ETC‚ a process known as oxidative phosphorylation. The gradient acts to power the ATPase‚ so that it may phosphorylate ADP to produce ATP. The reverse reaction of this process‚ or hydrolysis of ATP into ADP and Pi‚ may be used to observe ATPase activity when the resulting Pi is quantitatively measured

    Cell Respiration Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose‚ which has energy stored in its chemical bonds. You can think of glucose as a kind of cellular piece of coal: chock-full of energy‚ but useless when you want to power a stereo. Just as burning coal produces heat and energy in the form of electricity‚ the chemical processes of respiration convert the energy in glucose into usable form. Adenosine
