Electrical Installations Electrical apparatus and wiring systems are to be constructed and installed in accordance with the requirements of this Section. Standard Distribution System The following are recognized as standard systems of distribution. Distribution systems differing from these will be specially considered. • Two-wire direct current • Three-wire direct current • Two-wire single-phase alternating current • Three-wire three-phase alternating current • Four-wire three-phase

for a powerful motivational paper. The problem was the research. Either the sources were outdated and came from skeptical websites‚ or the evidence proving global cooling was disproved by the same source in a later paragraph. For example‚ the website SkepticalScience quotes scientist Matt Vooro and others for predicting imminent cooling due to data that suggests the leveling off of warmer temperatures yet dismisses their claims after evaluating that their field was not climate science and that an

warmth receptors send a message to the hypothalamus that there is an increase in body temperature. The thermostat centre in the anterior hypothalamus activates the cooling mechanism through nerve impulses (effectors) which are sent to the required region. Therefore cooling responses will begin to re-establish homeostasis. One of these cooling responses to re-establish homeostasis is vasodilation. Vasodilation occurs when the blood vessels expand (i.e. get wider / dilate) which causes an increase in blood

With each eruption‚ volcanoes have the potential to eject large amounts of ash‚ gases‚ and sulfuric aerosols into the upper troposphere and stratosphere (Allen‚ 2015). Volcanism helped form Earth’s ancient climate and influences climate change in today’s world (Kasting‚ 1993). A recent example of a volcano influencing climate include the 1982 El Chichon eruption in Mexico‚ which is regarded as the largest volcanic disaster in modern Mexican history (Mass‚ 1989). Ancient examples of climate-changing

Discussion The AHU and air distribution layout design for Block H is determined form cooling load calculation. There are several parameters and assumptions taken into account during the calculation. One of the assumption made is that the building has just been refurbish so air infiltration is minimize. The calculation part consists of the external load‚ internal load‚ total cooling load‚ duct sizing‚ piping sizing and AHU specifications. Since it will be used for commercial building‚ the system
