However, as soon as occupants are introduced into the building, there is now a requirement for access from one compartment into another, so an opening must be introduced [] . As any such aperture has the potential to allow the passage of fire and its by-products to circumvent the fire resistant compartment; i.e. a door, passage for a pipe, etc (see diagram), this defeats the objective of compartmentation unless suitable protection is provided, i.e. a fire door, shutter, etc. The...
There will be a progressive scarcity of the fossil fuel products if immediate and innovative measures are not taken for its sustainable use. There is also a need to develop sustainable and renewable alternatives. In fact, bioenergy derived from sources such as starch from corns, sugar from cane, and oils from plants will play an essential role in reaching targets to replace petroleum-based transportation fuels as a cost-effective and environmentally sustainable alternative and in reducing...
World energy crisis and biomass energy. As everyone have been told the energy crisis is coming, because the most of resources people are used now is nonrenewable."If oil production remains constant until it's gone, there is enough to last 42 years. Oil wells produce less as they become depleted which will make it impossible to keep production constant. Similarly, there is enough natural gas to last 61 years and there is enough coal to last 133 years."(The Global Energy Crisis, 2009) ...
This paper is based on the study of Environmental and Water industry in India. The objective behind this study is to analyze the industry, while understanding its key features, strategic advantage and the future of this industry. Environment and water are the key necessities of any country and as India experiences heavy pollution, it needs a rapid development. Firstly, Environment and water industry is analyzed using porter 5 forces framework which helps in locating competitive forces, and then...
Weather affects everybody. Consequently it is of interest not only to residents of an area, but also to visitors. The following information is designed only as a general survey; one to give residents more knowledge of their environment and tourists an idea of what can be expected. Melbourne enjoys a temperate climate with warm-hot summers; spring and autumn are balmy and mild, the winters cool. Melbourne is seldom unbearably cold or unbearably hot, temperature extremes when they do occur see...
Climate changes represent one of the biggest dangers the planet is facing. If the temperature Earth increases by more than 2C above pre-industrial levels, it is likely that climate changes will become irreversible, term consequences could be immeasurable on a long period of time. Low areas on Earth, including large parts of many European countries could eventually disappear under the growing sea level. In addition, many parts of the world fresh water sources would not be sufficient to cover the...
In This paper, the accuracy performance of training, validation and prediction of monthly water quality parameters is discussed when utilizing Adaptive Neuro-Fuzzy Inference System (ANFIS). This model analyze historical data were generated through continuous monitoring stations of water quality parameters (dependent variables) of Johor River in order to imitate their secondary attribute (independent variables). Nevertheless, the data arising from monitoring stations and experiment may be...
Flooding can be defined generally as a momentary condition of incomplete or absolute inundation of areas resulting from the overflow of tidal or inland waters by the increasing runoff of surface waters from any source (Australian Government Geoscience Australia. (2010). What is a flood?). It is often caused by heavy rainfall when natural watercourses such as rivers and lakes are unable to cope with the excess capacity of water (Australian Government Geoscience Australia. (2010). What causes...
By far the greatest sources of marine pollution are those that are land-based. For both pollution mitigation purposes and the conservation of marine biodiversity it is critical that international efforts to address land based sources of marine pollution are accelerated. In answer to this pressing need and as a result of Agenda 21, the Global Program of Action for the Protection of the Marine Environment from Land-Based Activities (GPA) was adopted by over 100 governments, including Australia,...
Reverse Osmosis (RO) is the finest water purification technology in the world. !t involves the passage of water from the section containing lower concentration of ionic substances to a higher concentration section when the two are separated by a semi-permeable membrane. In RO, sufficient pressure is applied to force the water to flow through the membrane in a reverse direction. Thus, pure water is produced by screening out dissolved salts and other contaminants. It can improve the color, taste...
