Dota 2 An Online Multiplayer Video Game - 1274 Words

In 2015, Dota 2, an online multiplayer video game, held a competition that consisted of over sixteen teams and 80 players from all over the globe. The action-packed event located in Seattle, Washington had a prize pool of over 18 million dollars. Since its conception in 1972 with the iconic game Pong, the video games have boomed into a 15-billion-dollar industry. Video games have now turned into an eSport, with thousands of athletes participating and even Call of Duty, a shooter game, hosted at X-Games. In addition to that, the United States now recognize eSports players as professional athletes, this means players can now have a visa under that title. Video games now have been tightly integrated into popular culture that second thoughts about video games have arisen. Video games have gained popularity mostly in teen and mature rated games. According to researched conducted by The Entertainment Software Association(ESA), the U.S. association representing video game publishing compani es, found that within the top 20 best-selling video games in 2015, half of which are rated teen or mature. With so many violent video games sold, a great deal of controversy has arisen, question the effects of video games in the most popular age group, young children. In 2012, a tragic school shooting occurred at Sandy Hook Elementary School in Newtown, Connecticut. The perpetrator, a 20-year-old Adam Lanza, shot 20 children and six staff members fatally.

Land That Contains Substances Environmental Sciences Essay Free Essays

Metallic elements have played an of import function in the development of adult male, gold and Cu, both native metals have been worked into desirable objects since 15000BC. ‘Advanced ‘ smelting techniques were developed by 4000BC, used to pull out Cu from ores and within a farther 1,000 old ages, other metals were being extracted, including Ag, lead, Sn and Zn. The development of the blast furnace centuries subsequently led to the big scale production of Fe and steel ( sgm. We will write a custom essay sample on Land That Contains Substances Environmental Sciences Essay or any similar topic only for you Order Now ac.uk 2002 ) . The last 100 old ages has seen Great Britain shaped by the ‘great ‘ industrial revolution and witnessed the development of a overplus of industries, notably, the steel, coal and chemical industries. Industrial ‘visionaries ‘ , focused on the development of industry had non planned a sustainable hereafter and the effects to the environment were overridden by enlargement. It is this deficiency of planning that has led to historical industrial procedures leting waste to be disposed of by merely tipping it onto the land, chemicals and natural stuffs were frequently spilt in situ ensuing in land taint ( sepa.org.uk 2012 ) . Contaminated land Land that contains substances in or under the land that are considered to be a possible jeopardy to human wellness or the Environment is considered to be ‘Contaminated ‘ ( environmental-protection.org.uk 2012 ) . Contamination can be categorised into assorted signifiers and can impact in different ways, depending upon legion factors including ; type, concentration and the nature of the substance ensuing in a huge array of impacts to both human wellness and the environment ( sepa.org.uk 2012 ) . A study undertaken by the British Geological Survey ( BGS ) in 2009, estimates that in England entirely, there are around 15,470 hectares of land that is classed as contaminated ( nerc.ac.uk 2009 ) . Contamination is assessed on a site – site footing, in a command to ease the deployment of the most efficient and operable technique. In order to find the best technique, inside informations of the contamination ( s ) contained within the dirt foremost necessitate to be assessed along with the type of land stuffs present at the surface and in the subsurface ( defra.gov.uk 2010 ) . Following initial probes, contaminations can be determined and classified into groups depending on their belongingss ( organic or inorganic ) ( Brown 2009 ) . Table 1: Contaminant categories used to find redress technique applied. Adapted from ( defra.gov 2010 ) . Organic Typical illustrations Halogenated volatile organic compounds ( VOCs ) 1-chlrobutane, methoxyflurane, pentafluoropropan-1ol Halogenated semivolatile organic compounds ( SVOCs ) Chlorophenol, Tetrachlorophenol, Chlordane Non-halongenated volatile organic compounds ( VOCs ) Benzene, Xylene, propanone, Carbon disulphide Non-halongenated semivolatile organic compounds ( SVOCs ) Polycyclic aromatic hydrocarbons ( PAH ) , phenol Organic Corrosives Acetic acid, aminobenzine Organic nitriles Organonitriles Polychlorinated biphenyls ( PCBs ) PCB ( Arochlor ) -1016 Pesticides / weedkillers 4, 4-DDT, Heptachlor Dioxins / Furans 2,3,7,8-tetrachlorodibenzo-p-dioxin, 2,3,7,8-tetrachlorodibenzofuran Inorganic Metallic elements Lead, Mercury, Chromium, Zinc Radionuclides Radioactive isotopes of U, radon Corrosives Hydrochloric acid, sulfuric acid Nitriles Metallic nitriles Asbestos Blue, brown, white Misc Explosives 2,4,6-trinitrotoluene ( TNT ) , hydrazine Table 1 is intended to supply a fundamental position of the categorization of contaminations, measuring the rightness of redress techniques is a complicated procedure in world, in world, several constituent contaminations will be contained within the mark site, each class of contamination would be assessed separately to measure the pertinence of a redress technique ( epa.gov 2012 ) . Redress of contaminated land Environmental hazards associated with contaminated land are typically remediated – a technique that seeks to take contaminations contained within the dirt ( ny.gov 2012 ) . Redress techniques are typically capable to an array of regulative demands – Part 2A of the Environmental Protection Act 1990 that is based on the likeliness of important injury to human wellness and important pollution of the H2O environment ( northdevon.gov.uk 2012 ) . Appropriate redress The appropriate redress solution should be implemented to ensue in the land being ‘suitable for usage ‘ . Remediation should render the land no longer contaminated and the effects of any important injury, or pollution of controlled Waterss that has occurred has been remedied, the suitably selected redress technique can in many state of affairss see the degree of taint reduced to such a degree that any considered important hazard is minimum, this does non nevertheless connote that all contaminations are removed wholly, in some state of affairss the contaminations are at such low degrees that they pose no hazard or that they are for good contained unmoved ( environment-agency.gov.uk 2004 ) . Remediation engineerings available Historically, the redress of contaminated land can be expensive and relies to a great extent upon procedures that are basically really proficient ( defra.gov.uk 2010 ) . Many of these procedures have involved heavy technology solutions, although considered to be really effectual, and in many instances, the merely feasible option, they have high environmental, societal and economic impacts ( clu-in.org 2012 ) . Categorization of dirt redress engineerings Soil redress engineerings can be categorised into four distinguishable wide categories ( Table 1 ) harmonizing to the cardinal rules involved in the remotion / containment of contamination ( s ) which can be farther sub-divided into unmoved and ex-situ techniques ( ehu.es 2012 ) . In situ clean-ups require no digging of contaminated stuff, in situ techniques are frequently preferable because of their lower application cost ; nevertheless, the general consensus is that these techniques take longer to make the preferable position and are more hard to supervise because of non-uniformity in intervention because of discrepancies in dirt stuffs ( DETR 1998 ) . Ex situ attacks ( digging of a contaminated country ) and handling it on site ( antique situ, on-site ) or transporting it to a distant site for ‘cleaning ‘ ( ex situ, off-site ) is by and large considered to be the more expensive option given the logistics of the operation, nevertheless, ex-situ techniques present the advantage of taking the bulk of taint forestalling farther spread ( iastate.edu 2012 ) . Table 1: Overview of both in situ and ex situ redress engineerings available, adapted from: ( defra.gov. 2010 ) . In-situ Technology Biological Physical Chemical Thermal Chemical oxidization and decrease i Electro – redress i i Enhanced bioremediation utilizing redox amendments i Blushing i i i Phytoremediation i Air Sparging i Biosparging i Stabilization and hardening i i Thermal Treatment i Venting i i Vitrification i i i Ex situ Biopiles i Slurry stage bioreactors i Chemical oxidization and decrease i Soil lavation and separation procedures i i Stabilization and hardening i i Thermal desorption i Incineration i Ex situ dirt vapour extraction i i Vitrification i i i Water and gas / vapour intervention i i i Biological redress engineerings Bioremediation uses micro-organisms ( barm, fungi or bacteriums ) to degrade organic contaminations ; bioremediation can be carried out both unmoved and ex-situ. The contaminations act as a nutrient beginning for the micro-organisms that break them down. Aerobic processes require a beginning of O, chase awaying C dioxide COa‚‚ and H2O H2O ( clu-in.org 2012 ) ( Figure 1 ) Figure 1: Conventional diagram of aerophilic biodegradation in dirt ( tamu.edu 2008 ) . Ex situ techniques include slurry-phase bioremediation, a procedure of keeping contact between micro-organisms and contaminations by adding H2O to contaminated dirts to organize ‘slurry ‘ ( iastate.edu 2012 ) . Other bioremediation techniques include ; Bioventing Injection of H peroxide ( H202 ) Solid stage bioremediation Landfarming Dirt biopiles Composting ( clu-in.org 2012 ) . Bioremediation is an economical procedure for a wide scope of applications of organic wastes. Many of the procedures can be handled in situ avoiding the demand to transport risky stuffs from site ( sa.gov.au 2005 ) . Physico – Chemical interventions Physical methods of dirt renewal are those that do non alter the physic-chemical belongingss of the pollutants accumulated in the dirt to be cleaned ( cieh.org 2007 ) . Physical redress techniques include simplified procedures such as dirt extraction and storage of contaminated dirts along with more complicated and technological techniques ( defra.gov.uk 2010 ) . In the physical procedures, the stage transportation of pollutants is induced. In the chemical processes, the chemical construction of the pollutants is changed by agencies of chemical reactions to bring forth less toxic or better dissociable compounds from the solid matrix ( unido.org 2012 ) . Physical redress techniques offer a cost effectual solution that can be concluded comparatively rapidly, and devour really small technology or energy resources ( eugris.info 2012 ) . Physical applications can be engaged both unmoved and ex-situ, and have the advantage that a wide spectrum of pollutants can be removed from the contaminated site and that they can be widely administered ( little, local sites ) ( unido.org 2012 ) . Physical-chemical interventions include ; Dirt Blushing Dirt lavation ( Figure 2 ) . Fracturing hypertext transfer protocol: //renewcanada.net/wp-content/uploads/2010/03/swallowtail2.png Figure 2: Dirt rinsing technique ( renewcanada.net 2010 ) Thermal interventions It is by and large considered that thermic procedures are the most dearly-won, nevertheless, a speedy redress clip is offered as compensation ( unido.org 2012 ) . Thermal redress involves the debut of hydrocarbon contaminated dirts into a het vas and retaining those dirts until they reach a unvarying temperature. Contaminants are heated by the thermic procedure, heat is applied to increase the volatility, to fire, break up, destruct or run the contamination. The hazard of let go ofing dioxins into the ambiance is an of import consideration and hence, runing temperatures are limited to 800A °F ( purdue.edu 2006 ) . Factors that influence the timescale of effectivity are the type and sums of contaminations present that scope from site to site, the physical size of the site and dirt stuff nowadays ( clu-in-org 2012 ) . Thermal techniques can be applied both unmoved and ex-situ, the rule advantage of unmoved techniques is that dirt can be treated without the demand to take and transport cut downing operating costs, nevertheless, unmoved techniques by and large take longer to de-contaminate a site and cost nest eggs are negligible. Ex-situ techniques involve the digging and remotion of contaminated dirts where they are exposed to high temperatures in intervention cells ; the cells contain contaminated media during the application. Although ex-situ techniques offer a decreased intervention clip, increased logistical deductions offset intervention costs ( clu-in-org 2012 ) . Thermal techniques typically include ; Hot gas taint Vitrification Injection of hot air Thermal Conduction Additional techniques are shown in tabular array? hypertext transfer protocol: //www.emis.vito.be/sites/default/files/data_sheets/migrated/schema % 20thermische % 20reiniging.PNG Figure 3: Diagram of thermic cleaning ( vito.be 2012 ) . 2.0 A critical appraisal of the effectivity of dirt redress techniques and the protection of groundwater 2.1 The Groundwater system â€Å" The largest available reservoir of fresh H2O † ( Environment-agency.gov.uk 2012 ) Water that is continually traveling through the environment is known as the H2O rhythm, nevertheless, most of the rain that falls will be soaked up by dirt, through the procedure of infiltration, H2O will soak farther down into the land and finally into underlying stones, this is known as groundwater ( groundwateruk.org 2012 ) . 2.2 The importance of groundwater 70 % of the planetary capacity of fresh water is groundwater, 30 % of this sum is found within rivers, lakes and watercourses, many of these rivers and lakes etc. are fed straight by groundwater, it can non be underestimated how much groundwater plays an of import function within the human civilization, groundwater is the line of life afforded to planetary wetland sites and a major helper to industry in a planetary context ( environment-agency.gov.uk 1999 ) . Whilst groundwater is by and large of good biological quality, it is invariably threated by contaminations, pollutants that seep through the surface and into the groundwater system, pollution occurs from diffuse beginnings when a pollutant is spread onto the land in the signifier of an applied agricultural pesticide for illustration and besides from point beginning pollution, where a chemical spillage has occurred for illustration. Some pollutants inputs will of course degrade or will be filtered out as the H2O flows through permeable stones, but on many occasions, the pollutants are relentless types and have to be subjected to typically dearly-won redress procedures ( groundwateruk.org 2012 ) . Figure 4: ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ( mfe.gov.nz 2007 ) . 3.0 Are dirt redress engineerings effectual at protecting groundwater? The mobility and destiny of contaminations that enter dirt are determined by a figure of factors ( postpone? ) , in order for a comprehensive and realistic site hazard appraisal to be carried out, consideration should be given to the nature and prevalent conditions in the dirts, including ; geology, hydrogeology, hydrology, contaminant geochemistry, geotechnics, ecotoxicology and microbiology, one time these have been decently addressed, a predicted behavior theoretical account of the contamination can be produced to help in the choice of the most efficient and cost effectual redress technique ( eugris.info 2012 ) . Relevant dirt and groundwater belongingss may include: Relevant contaminant Physico-chemical belongingss may include: Soil profile Contaminant concentration Dirt texture ( comparative proportions of sand, loam and clay ) Chemical speciation e.g. the valency or oxidization province of a metal Presence of mineral components such as clays, carbonates, phosphates, oxides and organic affair ( expressed as the fraction of organic C foc ) Solubility in H2O ( or other dissolver if a non-aqueous free stage liquid is present ) Moisture content Sorption ( soil-water divider coefficient Kd and organic carbon-water divider coefficient Koc ) Particle size distribution Octanol-water divider coefficient ( kow ) Bulk dry denseness Vapour force per unit area Porosity ( air-filled and water-filled ) Henry ‘s Law invariable Sorption capacity of the dirt Biodegradation pH and redox possible Nature of metabolites Microbial populations Vegetable consumption ( dirt to works concentration ) Elevation of H2O tabular array Weathering possible Groundwater flow way Diffusion coefficient in air Hydraulic gradient Diffusion coefficient in H2O Hydraulic conduction Viscosity ( gases and bluess ) Hydraulic dispersivity Viscosity ( non-aqueous stage liquids ) Table? : Factors act uponing the destiny and mobility rate of contaminations in dirt, adapted from ( eugris.info 2012 ) .
