Redox reactions (Redox terminology‚ galvanic cells‚ standard electrode potentials‚ strength of oxidizing/reducing agents‚ corrosion and protection against it) Oxidation is defined as the loss of electrons and reduction is defined as the gain of electrons. Oxidizing agents‚ such as oxygen are defined as substances which accept electrons; reducing agents are substances which donate electrons. Redox reactions are: a) The reactions of metals with non-metals 2Na+Cl2→2Na+Cl- b) The reactions

natural or original alignment is displaced. Therefore to repair the break‚ the fragmented bone must be aligned to ‘reduce’ the fracture; hence the term reduction. However‚ the type of fracture determines the type of reduction procedure needed. There are two forms of reduction available to patient. The two kinds of reduction are; • Closed reduction of a fracture is the treatment where the bone fragment is aligned through manual manipulation. This treatment uses splints or cast to aid in the immobilization

official poverty line has declined very slowly and unevenly in the past four decades‚ and poverty reduction has been much slower than in neighboring countries such as the People’s Republic of China (PRC)‚ Indonesia‚ hailand‚ and Viet Nam. he growth of the economy has been characterized by boom and bust cycles and current episodes of moderate economic expansion have had limited impact on poverty reduction. Other reasons for the relatively moderate poverty decline include the high rate of inequality across

LEVELLING Aim: to learn the basic levelling principles‚ theory and applications and to be able to book and reduce levelling data. Levelling refers to height measurements for representing the relative difference in height (altitude) between various points on the earth’s surface. Basic equipment (a) A device which gives a truly horizontal level (the Level). (b) A suitably graduated staff for reading vertical heights (the Levelling Staff). Types of levels (a) Tilting – adjustment of level bubble

scrap and/or DRI materials. In recent times‚ EAF steelmaking technology has evolved closer to oxygen steelmaking as more chemical energy is introduced into the process. Direct-reduced iron (DRI)‚ also called sponge iron‚ is produced from direct reduction of iron ore (in the form of lumps‚ pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture‚ the majority of which is hydrogen (H2) and carbon monoxide (CO) which act

Emissions trading allows countries that have emission units to spare – emissions permitted to them but not “used” – to sell this excess capacity to countries that are over their targets. Thus‚ a new commodity was created in the form of emission reductions. Since carbon dioxide is the principle green house gas‚ people speak simply of trading in carbon. Carbon is now tracked and traded like any other commodity. This is known as the “carbon market” (Emissions Trading‚ 2012). The

Supply reduction; demand reduction and harm reduction is a simple concept for a difficult issue facing society. Supply reduction aims to disrupt production and distribution of illicit drugs‚ which health care professionals and policy is not part of‚ this is a role for law enforcement and not for health care workers. Demand reduction is reducing demand for taking or starting to take harmful
