Metal fabrication is the building of metal structures by cutting‚ bending‚ and assembling processes: Cutting is done by sawing‚ shearing‚ or chiseling (all with manual and powered variants); torching with hand-held torches (such as oxy-fuel torches or plasma torches); and via numerical control (CNC) cutters (using a laser‚ mill bits‚ torch‚ or water jet). Bending is done by hammering (manual or powered) or via press brakes and similar tools. Modern metal fabricators utilize press brakes to either

Extraction of metals The History of Metals. Metals have been used by people for many thousands of years. Gold and silver‚ found as native metal‚ were used both as jewellery and as a status symbol - nothing new there. These metals were known in the Stone Age‚ but gold and silver are too soft to be used as tools. The first really useful metal to be discovered was bronze. This began the Bronze Age. Bronze was used extensively for tools and weapons in Asia and Africa from 4‚500 B.C. (6‚500 years

and various projects is to simply listen to music. Music is very popular to our specific age group‚ but is consuming different styles of music necessarily a healthy alternate to the stress?

Alkali Metals Introduction Alkali metals refer to six elements belonging to the Group IA of the long form of the Modern Periodic Table‚ viz. Lithium (Li)‚ Sodium (Na)‚ Potassium (K)‚ Rubidium (Rb)‚ Cesium (Cs) and Francium (Fr). Fr is a radioactive element. These elements are called so because they form strongly alkaline oxides and hydroxides. Electronic Configuration of Alkali Metals Each of the alkali metals has one electron in their outermost (valence) shell‚ which is just outside an inert

Transition Metals 1a) The d-orbitals of a free transition metal atom or ion are degenerate (all have the same energy.) However‚ when transition metals form coordination complexes‚ the d-orbitals of the metal interact with the electron cloud of the ligands in such a manner that the d-orbitals become non-degenerate (not all having the same energy.) The way in which the orbitals are split into different energy levels is dependent on the geometry of the complex. Crystal field theory can be used to predict

Foreign Studies Studies on the effects of retention follow this design: Researchers identify a group of students who have been retained in a grade. Then they find another group‚ matched in relevant characteristics to the retained group‚ which had instead been promoted to the next grade. Usually‚ the groups are matched on achievement test scores so that they wereequally low before the retention or promotion occured. Then‚ the achievement test scores of the two group are compared at the end of
