Gear in Draw-works. Draw-works is the machine on the rig consisting of a large-diameter steel spool‚ brakes‚ a power source and assorted auxiliary devices. The primary function of the draw works is to reel out and reel in the drilling line‚ a large diameter wire rope‚ in a controlled fashion. The drilling line is reeled over the crown block and traveling block to gain mechanical advantage in a "block and tackle" or "pulley" fashion. This reeling out and in of the drilling line causes the traveling

In fact where she lives is very mysterious and smelly too. This is because her home is underneath the surface of the earth

smallest entities which resemble the properties of an element and cannot be broken down into smaller parts. Molecules are formed when two or more atoms are combined. This formation can happen in a variety of ways. When two oxygen atoms join O2 is formed‚ and when three oxygen atoms join O3 or ozone is formed. Both of these have different properties. Different atoms can also combine to form molecules. Hydrogen combines with sulfur to form H2S and hydrogen and oxygen also combine to form H2O. Dmitri

Campbell’s Biology‚ 9e (Reece et al.) Chapter 5 The Structure and Function of Large Biological Molecules In Chapter 5‚ the principles of chemistry covered in earlier chapters are applied to the understanding of biological polymers and lipid membranes. The emphasis is on properly linking monomers and their polymers‚ and on the structural and functional diversity of the different polymer types. Particular attention is given to protein structure‚ because this is central to understanding subsequent

community decides to legalise some form of gambling‚ they decide in favour of the benefits over the costs. The benefits usually consist of increased revenue to government and increased control over criminal activity associated with illegal gambling (p.1). It is contradicted from Islamic perspective.

Biological Molecules Introduction: Without carbon‚ nitrogen‚ hydrogen‚ sulfur‚ oxygen and phosphorus‚ life wouldn’t exist. These are the most abundant elements in living organisms. These elements are held together by covalent bonds‚ ionic bonds‚ hydrogen bonds‚ and disulfide bonds. Covalent bonds are especially strong‚ thus‚ are present in monomers‚ the building blocks of life. These monomers combine to make polymers‚ which is a long chain of monomers strung together. Biological molecules can be
