Controlling Carbon Dioxide Emissions Although Carbon is a very scarce element –it is less than one percent of the total composition of elements on Earth-, it forms an essential component of organic matter. It is able to live in all of the different spheres of the earth (in different forms). We need carbon to survive, but in some ways it can be very harmful. Due to that fact, many people are trying to control the amount of carbon dioxide emissions. Many have tried finding out ways to…

The earliest automobiles were powered by steam; however, it was a very poor power source due to its price, weight, start-up times, and tendency to explode. The development of automobiles was limited until a better power source was established. In 1834 the first practical motor was developed by Moritz Jacobi (Doppelbauer). Even though this was a motor the motor wasn’t strong enough to drive an automobile. In 1884 a man named Thomas Parker built the first practical electric automobile (“World's…

Heating, ventilation, and air conditioning (HVAC) systems in commercial buildings are responsible for consuming more than 40 percent of the total energy usage. Keeping it running properly and at peak efficiency is one of the important steps in energy management. A good system maintenance is more than just controlling energy usage. Besides people comfort, today's buildings depend on HVAC systems for other important reasons too. For example, most telecommunication systems need specific…

6.1 Legal clauses The PSC provides an elaborate mechanism for the control and supervision of of the activities relating to the exploration, discovery, development and production of crude oil/natural gas and associated hydrocarbons from the relevant field. It distributes title over the crude oil/natural gas and associated hydrocarbons between the government and each of the consortium members. The various clauses are being described below under various sub heads. 6.1.1 Rights granted by PSC The…

the Waterfall or the Modular Incinerator, however the toxicity of the entire process is way too large to undergo on a large scale. In terms of the crops which can be used for biofuels, switchgrass is one of the best crops available for use inside a coal power plant as it has a very low amount of residue left over and it can be very easily…

Coal is a commodity, which has impacted the economy, environment as well as the human history in the 19th century. The production of coal started as early as the 18th century, in Britain, but in very little quantities. It produced these quantities because of the types of mining techniques practiced in that era, such as the bell pits and drift mines. The mine places were small, and the market for the coal was domestic. Industrial revolution occurred during the era of production of coal. It is the…

3.2. Phosphorus recovery in MEC When the pH of the cathode chamber reached 8, P started to precipitate as struvite. The reactor accomplished a peak precipitation efficiency of 94%. Recovery of P was in the cathode chamber, where the neutral solution was converted to alkaline by proton consumption. Previous studies reported similar results, like Cusick et al. (2014) and You et al. (2016), where high P removal was carried out by MEC (85%) and MFC (82%), respectively. Cathode pH was affected by…

The word crucible has three defintions. The first defintion is a pot which, because it can withstand great heat, is used to melt iron and other metals. The second definition is a severe test or hard trial. The third definiton is an adjective used to describe a very high grade of steel. In Arthur Miller’s play, The Crucible, John Proctor fits all three of the definitions of the word crucible. The first definition of the word crucible is a pot which, because it can withstand great heat, is used…

Froth Treatment: Oil Sands Bitumen Recovery Introduction This description will give you an understanding of the fundamentals behind the Bitumen Froth Treatment process, as performed at Naphthenic Froth Treatment (NFT) operating sites. Bitumen is the valuable hydrocarbon component of the ore formation which begins in the ground, and is extracted by the Mining department. Prior to entering the Froth Treatment facility, the Bitumen Froth is created by mixing the ore with hot water for…

transitioning from coal to oil as a primary source of fuel for industries in essentially already industrialized countries. In other words, the author primarily argues that the production, acquisition of energy and the emergence of democratic politics are inextricably linked. The author starts with a thought-provoking, but necessarily curious opening: “Fossil fuels helped create both the possibility of modern democracy and its limits” (1). I call this opening thought-provoking because it sort…
