How can the Footprint foster sustainable human development? How do carbon emissions contribute to humanity’s Ecological Footprint? Footprint Basics - Overview Humanity needs what nature provides‚ but how do we know how much we’re using and how much we have to use? The Ecological Footprint has emerged as the world’s

Chemistry Assessment Coal is a combustible rock of organic origin composed mainly of carbon (50-98%)‚ hydrogen (3-13%) and oxygen with lesser amounts of nitrogen‚ sulphur and other elements. Some water is always present‚ as are grains of inorganic matter that form an incombustible residue known as ash. In New South Wales‚ black coal is mined near the eastern and western edges of the Sydney-Gunnedah Basin where the seams are relatively close to the surface. Mining along the western edge‚ where

Continuum Percolation study of carbon nano tube composites via Size distribution effects. A.Afaghi ;S.Asiaei ;M.Baniasadi Mechanical engineering department;University of Tehran. The three-dimensional continuum percolation problem of hard-core and soft-core (permeable) objects was an area of active research in the 1980s[1]. Among the considered geometrical objects a very important category is the case of permeable sticks with the form of capped cylinders [2]. Advancements in capabilities of

“Global pollution creates a “public bad” born by all – a negative externality with a wide impact” (M.Harris‚ 2002). Australia is considered to be the driest populated continent in the world and faces stern drought and water shortages. Reducing carbon emissions is challenging for Australia‚ although the Government realizes that meeting this challenge is important and commits to reducing the level of pollution caused by greenhouse gases in Australia‚ and voluntarily preparing for an altered climate

polluting the environment because greenery add oxygen to environment filters the air. Atmospheric pollution as a result of emission of carbon monoxide‚ Sulphur oxides and hydrocarbons has become a subject of growing concern and has led to increasing pressure for restrictions of burning of fossil fuels. It is estimated that currently more than 20 billion tons of carbon dioxide are being released in the atmosphere in this way every year. The discharge of these air pollutants is infecting and destroying

The Iron-Carbon Diagram There are two iron-carbon equilibrium diagrams: - stable iron-graphite Fe-Gr - metastable iron-cementite Fe-Fe3C The stable condition usually takes a very long time to develop. The metastable diagram is of more interest. Fe3C iron carbide called cementite because it is hard. Following phases exist on Fe-Fe3C diagram: - liquid solution of iron and carbon (L) - ferrite ( ) – an interstitial solid solution of carbon in Fe (bcc). At room temperature ferrite is ductile but

Adventures of Zircon and Carbon Zircon and Carbon were brothers from the Triangulum Galaxy. They are two twin aliens that stood 6’7 and were a stunning color of mint green. They traveled 2.7 light years to get to Earth for a special mission. The mission was currently unknown. They were rushed on to a spacecraft and only sent with coordinates and supplies to lead them along the way. The coordinates they had read “Latitude: -64.15164‚ Longitude: -10.58414‚ Distortion: 5.26.” The spacecraft finally
