Children's Pastimes Today and Yesterday Outline Example | Topics and Well Written Essays - 500 words

Children's Pastimes Today and Yesterday - Outline Example The present paper has identified that in the olden times, the outdoor activities of children were far greater than they are today. Schools and educational institutions promoted scouting and recruited young scouts. This kept them busy with activities like camping and learning first aid techniques. Apart from these extracurricular accomplishments, the children also entertained themselves by playing outdoor games. These included football, hopscotch, and basketball. Board games and cards were other hobbies of these children who spent their time playing these games with their siblings and friends. Furthermore, life was not as fast-paced previously as it is today. Quality family time was a compulsion and children went to spend holidays with their family. Weekends at the beach or at the park were another favorite pastime. With the changing times and new innovations, the hobbies of children have altered. The internet and the computers have taken over the minds of the younger generation. Chil dren now prefer to play games on the computer or indulge in online gaming. Their other favorite pastime is watching television. Children nowadays spend up to 6 to 8 hours every day watching their favorite television programs. Indulgence in outdoor games has reduced and an inactive lifestyle has been adopted.

Dentistry - Annotated Bibliography Example People were determined as eligible on basis of their dental examination as well as history. Participants were also randomized into two groups into two arms in a design called parallel double blinded. Fifty eight partakers were randomized to study the DHA supplementation. Out of the 55 people who participated 27 of them had been randomly assigned to DHA. The rates of reaction for DHA +ASA were 79%. The data collected was managed using an electronic data capture platform and an analysis done using SAS 9.3. The 3 months randomized trial of using 2000 mg DHA with 81-mg ASA showed a significant improvement on periodontitis. The results clearly showed that DHA supplementation with low ASA dosage is effective in treating periodontitis. Additionally, it is safe and cheap. The article has different tables and graphs and statistics enhanced the validity and reliability of the results. The strengths of the study included verified adherence, consistency in outcomes and control procedures which w ere predominant throughout the study. On the other hand, the weaknesses included lack of proper limitation of measurement. The target audience in this study was medical experts and people suffering from periodontitis. The purpose of the study was to provide another option for treating periodontitis .The study will assist a lot of people in reducing their expenses in treating periodontitis which was previously treated using application of antibiotics and mechanical cleaning.

Security Essentials 1.5 Essay Example | Topics and Well Written Essays - 1000 words

Security Essentials 1.5 - Essay Example Contemporary society confronts security experts with distinct and frequently unprecedented security-associated concerns. The security sector was known as a growth sector even before 9/11 (Clifford, 2003). Affairs between civic law implementation agencies and private security experts in more recent years have been limited, even though it is purportedly transforming. History is full of cases where security purposes have been accomplished through the application of innovative minds, resourceful plans, and easily accessible solutions. Sectors evolve to meet these new social demands as society itself evolves. Exploration of artifacts offers evidence that shows attempts by the earliest communities to secure themselves from internal and external dangers. Particular communities discovered methods that were more dignified in an effort to assure security protection by building tools, starting agriculture, and settling in the long-term. These communities resided in regions with certain climates that presented particular security dangers as well as defenses (Clifford). Kangaroo justice was still a preferred option even after the establishment of formalized legislation in educated nations such as the United States. Historians commonly agree that tribal leaders or household members who represented the rest of the family determined security aims during eras that preceded recorded history and areas where legislations could not be implemented freely like the American Frontier. Archeological proof imply that civilizations dating as far back as five millennia BC designed and implemented laws to identify proper behavior. Ancient recorded attempts to build a series of criteria has been credited to the Sumerians as far back as five millennia BC. The Code of Hammurabi, 1750 BCE, is the later legal cannon that adopted Sumerian cannons, set up by King Hammurabi, and discovered in 1901. Draco’s Law applied to Athens in 621 BC and included punishments for numerous crimes that

Sardar Vallabhbhai Patel Essay Example for Free

Sardar Vallabhbhai Patel Essay All throughout the history of our great nation, there have been many leaders who left their mark with their invaluable contribution. I could very proudly name many such leaders starting from our very own â€Å"Bapu†, or Chacha Nehru or Netaji Subhash Chandra Bose. But one such great leader whom I would like to talk about today was arguably the most powerful leader who followed the footsteps of Mahatma Gandhi and gave shape to form ONE robust union from numerous small big princely states. The robust union whom we call â€Å"INDIA† – our great nation. He was the architect to bring unite people from Kashmir to Kanyakumari and from Junagadh to Guwahati to form our great nation. Respected Teachers Friends, I am talking about none other than The Iron Man of India, who was called as â€Å"SARDAR† respectfully by everybody although his real name was Vallabhbhai Jhaverbhai Patel. He was born on 31 October 1875 in Nadiad, British India. He was a lawyer by profession before he joined the congress under the leadership of Mahatma Gandhi. He and Bapu were the best of friends. He fought relentlessly the freedom struggle with Mahatma Gandhi and made his presence felt during the non co-operative movement. He went on to become the president of Congress Party and led the freedom struggle aggressively under the guidance of mahatma Gandhi. Just before independence he stepped down from the post of president at the request of Mahatma Gandhi, although all state units of the Congress Party wanted him to continue. He was the strong leader who picked up the challenge of integrating all princely states and territories including difficult one like Hyderabad and Junagadh and form our great nation. He became the first Home Minister of Independent India and he is still considered to be the best Home Minister ever. Apart from his political victories he also empowered the poor milk f armers from Anand Region who were getting exploited at the hands of middleman cartels. He showed them the path to form a CO-Operative society which will buy, process and sell their milk at fair price which can bring prosperity to their life. That CO-Operative movement went on to become the biggest Indian Brand in the world for food products the Brand which we all know as AMUL The seeds of amul were sawn by our very own Sardar. After suffering a massive heart attack (his second), he died on 15 December 1950 at Birla House in Bombay. His death is a huge loss to the Indian Society.

Why is China Called the Sleeping Giant?

Why is China Called the Sleeping Giant? China is a huge nation that has been experiencing unprecedented growth over the past few decades an average annual GDP of well over 10 percent. While Chinas actual per capita income is still classified in the lower-middle category in global statistics, at about $3,200, it is still the third largest economy in the world after the United States and Japan with a nominal DFP of $4.3 trillion (Chinese Government, 2010). Contemporary China now participates in the global private sector. Her companies play a major role in the global economy, and companies in the developed world take Chinese manufacturing trends quite serious. Chinas view of her economy is Socialism with Chinese Characteristics, which is defined variantaely by scholars. Over 1/3 of the economy is state owned and controlled, and there is significant new foreign investment in the country. Key government industries are utilities, heavy industry and energy resources. China is the worlds largest producer of rice, and is among the top producers of cotton, corn, tobacco, soybeans, and peanuts. Industrially, it is also a world producer in cotton products, coal, crude oil, and its mineral resources are among the richest in the world, albeit only partially developed. All this developed has resulted in Chinas populace seeing a gradual improvement in their living standard, even in the rural areas, but it is the cities in which the most vital and burgeoning growth occurs. Like any developing country, though, China has growing pains. It remains more concerned with State economic development that per capita improvement. Chinas growth may not, in fact, remain sustainable unless there is a dramatic change in the infrastructure and a redevelopment of natural resources that matches the needs of the global environment (e.g. human rights, pollution control, trade imbalances, etc.). Even with the new face, china still has severe corruption issues in the government, huge environmental issues, and a rapidly aging population w ith limited capital resources to sustain an older, non-working, population (CIA Factbook, 2010; National Bureau of Statistics of China, 2010). One very telling example is the way China has merged the political with global economic independence, and its ability to negotiate environmental issues. For the past fifty years, the country has spent considerable resource modernizing, coalescing power, investing in other countries, and changing the way it utilizes its greatest resource its population. Indeed, much of Chinas current strategic and tactical foreign policy surrounds its rapid growth over the last several decades and the way it has extended itself in so many directions. China is still dependent upon Middle Eastern oil importing up to 8 million barrels a day. The vulnerability also extends past oil dependence into fears of an energy insecurity peak. The emerging trends in China are that its energy needs are going to continue to exponentially increase, while if something is not done, there will not be the rate worker base to handle this segment of the market. And, to top it off, such rapid development coupled with global warming and pollution issues threatens to damage Chinas agricultural markets some areas must pollinate their trees and fields by hand (Shirk, 2007). Indeed, what seems to be happening with China is understandable the Developed World had their Industrial Revolutions and decades of pollution without control. Now the developing world is trying for rapid industrialization but has the added conundrum of restrictions, issues with global warming, pollution, and world opinion. Citing both qualitative and quantitative governmental data, authors Chung, Fryxell and Lo (2006) maintain that while China is overtly committed to promote programs that have environmental conservation as part of their template, the stark reality is that the country falls quite short of even its own basic standards. This revelation is based on the number of permits authorized for construction versus the number of ISO 14001-4 permits and requirements met (473-6). We must also take into consideration both the vastness of Chinas geography and the complexity of their bureaucracy. Governmental regulations are not always translated into actualities at the local level, largely due to enforcement and logistical issues, all politically based. Chinas Path Towards Modernization China did not experience an Industrial Revolution and modernization in the 17th, 18th and 19th centuries as did many European countries and even Japan, to some extent. Instead, throughout even the 19th century, China remained largely rural and controlled by a series of warlord governments. In fact, it was a series of civil wars, internal bureaucratic corruption, and imperialism that damaged the country and economy to the point that China was ripe for dramatic social and political change (China Country Profile, 2010). Once Japan had been defeated in 1945 another civil war erupted, this time between the Nationalists and the Communists. In 1949, the Communist regime, with the assistance of the Soviet Union, garnered victory and established The Peoples Republic of China on the mainland, with the Chinese Nationalist Party relegated to the island of Taiwan. Soviet influence was heavy, as it was in the conflict over the Korean peninsula in the early 1950s. Chinese leadership counted on Soviet aid for, even with a huge population they were in the midst of a serious economic decline. The Soviet political leadership had a vested interest in supporting the Maoist revolutionary group, not simply to export world communism, but to establish a communist state in Asia (Garver, 1988, 1-34). What followed were a series of rather disruptive socioeconomic movements designed to rapidly industrialize, collectivize, and change the landscape of China called The Great Leap Forward. Like the Soviet Union, peasant resistence and economic ineptitude resulted in an estimated 30-36 million deaths (Smil, 1999). Once the so-called old guard of the Communist Revolution died, though, it was time to rethink economic and political progress. By 1978 there was some relaxation of control, but the PRC still had iron-clad control over politics and society. Economic reforms were politicized and put into effect by Den Xiaoping decollectivization of the countryside, some political decentralization of control in the industrial sector and an amazing public pronouncement that the past few decades had been an appalling catastropheà ¢Ã¢â€š ¬Ã‚ ¦ the most severe setback to the socialist cause since 1949 (Poon, 2006). Politically, it was important to quickly develop the consumer and export sectors of the economy, and create and buttress an urban middle class, increase living standards, and deal with such issues as literacy, life expectancy, personal rights, and most especially, agricultural output. Knowing that things move slow politically and socially in China, we can now trace an important step in opening up China to the West both politically and economically. In 1972, while Mao was still alive but Deng controlling most of the upper echelons of political power, U.S. President Richard Nixon visited China, The results of the week long visit, most of it orchestrated by Henry Kissinger, were vast: a political agreement that there was only one China and an agreement to settle the Taiwanese situation; to open trade and commerce between China and the West; and to reduce tensions between the two countries. Nixon himself commented, This was the week that changed the world, as what we have said in that Communiquà © is not nearly as important as what we will do in the years ahead to build a bridge across 16,000 miles and 22 years of hostilities which have divided us in the past. And what we have said today is that we shall build that bridge (1972 in Review, 1973). The Way of the Sleeping Giant- Unlike the West, which had 150-200 years to accomplish the technological and social revolution of transforming from rural to urbanized-industrial economies, China has had less than 50 years. However, a combination of traditional Chinese Values, the Maoist push, and post-Maoist political expertise has positioned the country to become the next global superpower. Since 1949, there have been 3-4 major shifts in overall philosophy within the elite; as globalism continues to develop, China wishes to be part of the global economic push with import/export and fiscal rewards, so small concessions have been made over the past decade to allow greater autonomy in business ownership and purchasing decisions. There is high political, economic, societal, and military cohesion since all are central controlled and there is no evidence of a lapse in the power base. Most recently, China has been under international pressure for its continued censorship program (television, motion pictures, and the Internet) (World Bank, 2010). This paradigm shift can best be understood by looking at a Chinese tradition dating back centuries. However, to understand modern China, we must also understand the basis for Chinese culture Confucianism. It was Confucianism, though, that dominated ancient Chinese history as a socio-religious philosophy. The trend towards philosophical underpinnings, too, was part of Ancient Chinas view of law, order, and state control. Confucianism is a Chinese ethical and philosophical system based on the teachings of Confucius. It is a system that focuses on social, moral, political, and philosophical through, and stresses the important of education and the actualization of the individual. In combination, individuals then are able to govern the state by morality and virtue, rather than extreme coercion or violence (Sprunger). Unlike many religions, Confucianism expects to be part of the political/legal process and governance is part of the expectations of service by the populace. A basic sense of duty, honor, and bureaucratic hierarchy is part of the philosophy, as was a general view that people were generally good, wanted to exist within an orderly society, and only needed structure to remind them of the way of being good: This legalistic tradition is actually more of a political mindset that has been part of the way of Chinese politics for centuries. If we look at basic Maoism, we see that there are indeed some similarities, albeit with a Marxist bias. Maoism of course emphasizes the revolutionary struggle of the masses against exploiters, or a Peoples War. However, Maoism departs from Marxism because it is based on reforming an agrarian economy as opposed to an urban, industrialized state. The new communist leaders abandoned most Maoist practices by 1978, calling the new China which is a combination of ancient legalism, Maoism, and socialism, as Socialism with Chinese characteristics (Chung-Yueh Hsu, 1990, 168-72). Thus, the character and flavor of Chinese politics is shaped by a number of rubrics, all of which now combine to produce a country that may appear contradictory, but is in fact completely within character. This is illuminated given an overview of Chinas recent national goals and issues as they relate to both internal political stability and growth, and Chinas emerging position within the overall geopolitical landscape of the 21st century. These goals are broken down into three major parts; political, social, and economic, all interrelated to a political culture based on the past and moving forward. Political Harness nationalism in moderate and appropriate ways to retain control over divergent and large population. Political/Military Increase military spending and size of military structure -eventual goal is to field the most sophisticated Army in the world Political Cannot provide enough of its own energy needs, must use geopolitics to ensure development continues Political/Vulnerability Avoid, at all costs, a hostile world in which China is boxed in by USA/Japan/India/South Korea and Australia. Ensure Russian neutrality or support. Social Continue to support large domestic market and rising foreign investment. Social Manage rapid aging issues (32 years median age in 2010 to 45 in 2040) they will have the social burden of a rich country and the income of a poor country. Economic Manage Chinas vulnerability in production of goods to West in line with current economic crisis (e.g. smaller than needed orders for Holidays, etc.) Economic Diversify industry and become more self-sufficient in high-tech and other needed technological and industrial segments Economic/Political Improve infrastructure to ensure safety of population (e.g. earthquake proof buildings, higher building standards, etc.) Economic China shows no sign of slowing, and its overall strategic objectives were clearly stated in the Three Step Development Strategy of 1978: Step 1 -To double the 1980 SNP and ensure that the people had enough food and clothing to meet basic needs (attained prior to 1989). Step 2 To quadruple the 1980 GNP by the end of the 20th century (attained by 1995) Step 3 To increase per-capita GNP to the level of the medium developed countries by 2050, at which time modernization goals will be met (Mengin, 2002; Dahlman and Aubert, 2001). The trend that emerges, then, is a new China with clear ties to the old. With the aggressive nature of China in the global environment, many scholars, in fact, believe it will be China that dominates the 21st century the power base shifting from West to East. With 20 percent of all humanity, and a civilization with thousands of years of history and tradition, the new China is clearly poised to be the next global super-power (Jacques, 2009).

The shear strength of soils

The shear strength of soils Introduction The shear strength of soils is essential for any kind of stability analysis. Therefore, it is important to determine reliable values. For this purpose triaxial tests are most appropriate. Nevertheless, direct shear tests are mostly performed to determine the shear strength of soils. From the tests result a clearer picture of the soil strata, there will be Direct Shear Test where the data can be interpreted and correlated info soil parameters. The soil parameters will be designed accordingly to the characteristic of the soil at the site itself. This case study is about evaluating contamination for the specific site. It involves the interpretation and manipulation of data from the Shear test and chemical tests. The whole process will be determination of contamination and measure its effect on the soil and then propose some remediation practices and methods. Part (1) Soils Contaminants Soils are categorized according to the contaminants present (type and amount); Soils that contain contaminants below regulatory concern Soils that contain hazardous waste Non-hazardous 1. Hazardous Soil that contains hazardous waste must be managed as such when contamination is above the nonhazardous waste limits or is otherwise classified a hazardous waste. The only options for soils that contain a hazardous waste are on-site remediation or off-site management as a hazardous waste. 2. Non-Hazardous Contaminated soil is non-hazardous when both of the following criteria are met: a. The contaminant levels are above the most stringent soil cleanup criteria established by NJDEP. b. The waste is not classified as a hazardous waste. 3. Soils That Contain Contaminants Below Regulatory Concern Soils that contain contaminants at levels that are below the most stringent site cleanup levels established by NJDEP for a specific site are not of regulatory concern with the exception of sites in the Pinelands Area Brownfield sites come in all sizes and shapes The Brownfield Law created four different cleanup â€Å"tracks.† Cleanup levels at these tracks are based, in whole or in part, upon the sites future anticipated use. A site to be used for industrial purposes, for instance, would not have to be cleaned up as much as a site intended for commercial use. (See Appendix A for a description of each of the tracks). Clesn Up Site cleanups can be conducted by federal, state, or local government agencies and/or their contractors, by private parties responsible for the discharge of the hazardous substances, or by purchasers of land who did not cause the contamination but are willing to pay for and conduct the cleanup. Private parties can be directed by DEP to conduct cleanups or individuals can come to the department voluntarily and offer to do part of or all of a cleanup. Cleanups can be conducted to allow for any future use of the land: from residences, schools, and day care centers to commercial buildings, or new industrial uses. Cleanups can also be conducted to turn formerly contaminated sites into parkland for passive and/or active recreation. The level of cleanup required to protect human health and the environment is determined by the end use envisioned for the property. Obviously, cleanup to more stringent standards is required when people will be living on the property, or when sensitive populations such as children will be using the property for schools or recreation. Protectiveness can be obtained by either totally removing the contaminants of concern, or by treating them, or by limiting access to the substances by creating barriers to contact, such as with soil or other types of capping material. Certain cleanups can be conducted â€Å"at risk† by private individuals, with little oversight by the state. However, cleanups involving ground and surface waters must be conducted with DEPs oversight because the state is the trustee for those natural resources. Most parties conducting remediation will come to DEP for oversight if they desire a â€Å"No Further Action† (NFA) letter at the end of the process. That letter certifies that the states regulations have been met as of a specific date, as described specifically in the letter. With the NFA comes a â€Å"Covenant Not to Sue,† which defines those parties who are no longer liable to conduct additional cleanup at the site. Part (2) Direct Shear Test A. Shear Strength In the Mohr-Coulomb theory of failure, shear strength has two components: one for inherent strength due to bonds or attractive forces between particles, the other produced by frictional resistance to shearing movement The shear strength of cohesionless soils is limited to the frictional component. When the direct shear test is used to investigate a cohesionless soil, successive tests with increasing normal stress will establish a straight line that passes through the origin. The angle of inclination of the line with respect to the horizontal axis is the angle of internal friction. Values of the angle of internal friction are given in the following table. If the soil is dense when tested, initially higher values for the angle of internal friction will be measured, but with increasing amounts of strain, the angle will decline to the approximate ranges seen in the Table. SOIL TYPE ANGLE φ, DEGREES Sand and gravel mixture 33 36 Well-graded sand 32 35 Fine to medium sand 29 32 Silty sand 27 32 Silt (non-plastic) 26 30 The shear strength of a cohesive soil is more complicated than a cohesionless material. The differences are due to the role of pore water in a cohesive soil. Most cohesive soils in field conditions are at or near saturation because of their tendency to hold moisture and their low permeability. When load is applied to a soil of this type, the load is supported by an increase in the pore-water pressure until pore-water can drain into regions of lower pressure. At that point, soil particles are forced closer together and the strength increases, just like a cohesionless soil. Time is an important factor however, because it takes longer for water to move out of a low permeability material. Direct Shear Test: Results of the direct shear tests should be evaluated statistically. The statistical assessment in the shear box test includes the values of friction angle (Ï•) and cohesion (c), derived from the Mohr-Coulomb regression line, and the (original) measured values of peak shear strength. In previous publications only the derived parameters Ï• and c were taken into account. As the most important result the investigations have shown that it makes a remarkable difference whether the pair of variables Ï• and c or peak shear strength is considered. http://www.csus.edu/indiv/c/cornwell/engineering/9-20-06.pdf Direct Shear Box Test Procedure: 1. Bring the shear box together http://www.civil.mrt.ac.lk/docs/direct_shear_test 2. Compact the soil sample (which has reached the optimum moisture content) in the mould. 3. Place the sample into the shear box 4. Record the weight of the applied load and place the loading plate on top of the upper porous plate http://www.civil.mrt.ac.lk/docs/direct_shear_test 5. Remove the alignment screws to hold the shear box together. 6. Tighten the diagonally opposite screws to reduce the frictional force. 7. Reset the dial gauges. 7. Apply the normal load. 8. Start the motor to produce the desired constant rate of shearing 9. Take readings from the gauges, a) Proving ring. b) Horizontal displacement. c) Vertical displacement. 10. When the shear load starts to reduce or remains constant stop the test http://www.civil.mrt.ac.lk/docs/direct_shear_test A.

Part (3) Contamination Assessment PH Measurements: PH measurements were measured against TSS results, While no apparent correlation was found between pH and salinity; samples presenting higher pH generally had higher TSS concentrations, as indicated in the figure below. The addition of cement (and its effect on turbidity) appears to have had a noticeable effect on pH. In addition to the various testing that was performed as part of this study, two additional studies beyond the original scope were conducted: (a) an evaluation of the effect that organic content found within silt sediments would have on soil-cement hydration and strength gain, and (b) an assessment of whether the cement stabilization/solidification of contaminated sediments immobilizes organic and inorganic contaminants within the sediment. Part (4) Remediation. Chemical Fixation And Solidification Taking into consideration to select the best fit remediation method and conserve ecosystem and trying not to undergo major landscape disruption. One alternative to dredging and disposing of contaminated sediment is to solidify the sediment in-situ using CDSM, and cover the stabilized sediment with a cap. In this scenario, the mixing is a viable way to reduce the potential for highly contaminated sediments to be eroded over time by natural hydrologic events, vessel traffic or dredging. In situations where decisions regarding removal of sediment have not yet been made or if management alternatives (decontamination) are not yet fully developed, the CDSM technology can be used to stabilize sediment for later removal. Chemical fixation and Solidification, CFS, also commonly referred to as Solidification/Stabilization Treatment, S/S, is a widely used treatment for the management of a broad range of wastes, especially those classified as hazardous. The initial application of the technology in the United States dates back to the 1950s when it was fruitfully used to treat and dispose of radioactive waste. The USEPA considers S/S an established treatment technology, and has identified it as the best demonstrated available technology, BDAT, for 57 RCRA-listed wastes. It is anticipated that 30% of the CERCLA (Superfund) remediation sites include the use of S/S. There is an ample body of technical literature that documents the fundamentals for applying S/S, as well as the practical experience using the technology in a wide variety of wastes, contaminants and chemical matrices. The applicability of using S/S to immobilize the principal contaminants in the Passaic River sediments was evaluated. The following sections briefly summarize those findings. There are several additives mentioned in the literature as potential enhancers of the PCB immobilization. These depend on the particular conditions of the application: 1. Organically modified clays 2. Activated carbon 3. Ferric hydroxide 4. Rubber particulate A well-documented case where S/S was used for the immobilization of PCBs in contaminated soils is provided in the Yellow Water Road Dump in Duval County, Florida. Where In that case, a superfund site that started remedial action in 1984 was removed from the NPL in 1999. During the remedial activities, 4472 cubic yards of PCB contaminated soils were excavated and treated with S/S and placed back within the former operations area of the site. A groundwater monitoring program was established, and monitoring wells were installed to evaluate the future need for contingent pump-and-treat remedy. The site was monitored as part of the EPA five-year review program. In September 2000, the five-year-review report established that the selected remedy remained protective of human health and the environment. Site inspections and groundwater monitoring continue to ensure long-term protectiveness. Out-Of-State Recycling For recycling soils out-of-state, a written determination from NJDEP is required as to the non-applicability of the solid waste management regulations set forth in N.J.A.C. 7:26-1 et seq. For sites without a Site Remediation Program lead (i.e., Industrial Site Recovery Act, Bureau of Underground Storage Tanks, Bureau of Field Operations) and for the recycling of soil as a solid process waste, contact the Bureau of Resource Recovery and Technical Programs (609/984-6985). Sites with a Site Remediation Program lead must send this information in lieu of a Soil Reuse Proposal to the assigned case manager for an approval. The following are the standard requirements pursuant to (N.J.A.C. 7:26-1) for approval to send soils out-of-state: a. A letter, sent to the Bureau of Resource Recovery and Technical Programs from the generator of soil, certifying that the soil in question has been analyzed or is known in accordance with N.J.A.C. 7:26G-5.1 not to contain a hazardous waste. This also must include any necessary test results documenting that the soil contains constituents and hazardous waste characteristics below their regulatory levels. b. A letter sent to the Solid and Hazardous Waste Division from the receiving a facility stating that they agree to accept the specified amount of soil, indicating intention and method to beneficially use or reuse the soil and the time frame for such activity from the date of receipt at the facility. In addition, a copy of this information must be sent directly to the solid waste coordinator of the county of the soils origin. c. A letter sent to the Solid and Hazardous Waste Division from the proper regulatory agency of the receiving state or a copy of a current facility permit verifying that facility is operating in accordance with applicable rules and regulations and can accept the soils for the declared use/reuse. d. Once the soil is delivered to the identified use/reuse facility, a letter from the facility or a bill of lading stating the date and amount of soil received must be sent to Solid and Hazardous Waste Division and the solid waste coordinator of the county of the soils origin. Operational Landfill Cover Operating landfills that are permitted to accept ID 27 waste may use non-hazardous soil for daily landfill cover with approval from the Bureau of Landfill and Recycling Management. Fine grained soils which may create erosion problems or are easily windblown are prohibited for use as daily cover. Brownfield sites are found in both urban and rural settings and the present challenges that make the cleanup and redevelopment of these sites unique as compared with other real estate projects. Brownfield sites deal with four key issues, including: Environmental Liability Developers, land owners, and prospective associated with the propertys history can be successfully addressed. Financial Barriers Private financial institutions or investors may be reluctant to provide loans for sites impacted by real or perceived environmental contamination. Cleanup Activities Redeveloping a brownfield site may take longer than that of a typical real estate development if remediation is warranted. Feasible Reuse A viable plan for putting the site back into productive use based upon the localitys goals and well researched information are critical to successful redevelopment. Despite these challenges significant opportunities exist for brownfield redevelopment which can economically revitalize an area and improve the quality of life for communities. Brownfield redevelopment is also an ideal time to integrate a number of sustainability features that can result in improved storm water management, reduced air emissions and energy consumption, and preserve the history and culture of our communities. The purpose of this guide is to provide a starting point for information about brownfield redevelopment planning, regulatory considerations and resources available from the federal Environmental Protection Agency (EPA) and the Iowa Departments of Economic Development and Natural Resources. 6.

Under Track 1, a remedial program â€Å"shall achieve a cleanup level that will allow the site to be used for any purpose without restriction and without reliance on the long-term employment of institutional or engineering controls.† ECL 27-1415(4). With respect to soil remediation, the statute directs that Track 1 cleanups â€Å"shall achieve† the generic SCOs designed to allow for unrestricted future use of the property. Id. A developer who remediates a site to Track 1 standards receives a greater tax credit than is available for remediation under the other three tracks. Under Track 2, a remedial program â€Å"may include restrictions on the use of the site or reliance on the long-term employment of engineering and/or institutional controls.† ECL 27-1415(4). With respect to soil remediation, however, the statute directs that a Track 2 cleanup â€Å"shall achieve† the generic SCOs appropriate for the future use of the property â€Å"without the use of institutional or engineering controls to reach such objectives.† Id. Under Track 3, the developer does not need to achieve the generic SCOs, but instead â€Å"may use site specific data to determine† soil remediation objectives. ECL 27- 1415(4). Those sitespecific objectives must â€Å"conform with the criteria used to develop† the generic SCOs. Id. Like the generic SCOs, soil remediation objectives developed by the applicant pursuant to Track 3 â€Å"shall not exceed an excess cancer risk of one in one million for carcinogenic end points and a hazard index of one for non-cancer end points,† except where rural soil background contamination exceeds that risk level. ECL 27-1415(6)(b). A Track 4 remedial program â€Å"shall achieve a cleanup level that will be protective for the sites current, intended or reasonably anticipated residential, commercial, or industrial use with restrictions and with reliance on the long-term employment of institutional or engineering controls to achieve such level.† ECL 27-1415(4). The statute instructs that â€Å"[f]or Track 4, exposed surface soils shall not exceed the generic contaminant-specific [SCOs] developed for unrestricted, commercial, or industrial use pursuant to this subdivision which conforms with the sites current intended, or reasonably anticipated future use.† ECL 27-1415(6)(d). The statute defines â€Å"exposed surface soils† as â€Å"two feet for sites used for residential use and one foot for

Causes Of The Pelopenesian War Essay -- essays research papers

The Causes of the Peloponessian War   Ã‚  Ã‚  Ã‚  Ã‚  Ancient Greece during the 4th century B.C. was home to the city-states of Sparta and Athens. These two communities were the superpowers of the region during that time. The peloponnesian war between these two states evolved out of a string of events that would lead to years of conflict.   Ã‚  Ã‚  Ã‚  Ã‚  When looking for a single cause of the peloponnesian war none can be found. Over time many events contributed to the eventual war between Sparta and Athens. I believe the peloponnesian war evolved because of Athenian support for Spartan enemies, Spartan alarm at a rise in Athenian power, and the drastic differences between the two cultures.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  In 435 B.C., Corcyra, a Corinthian colony declared itself independent of Corinth. Corinth responded by sending a fleet to reduce the rebelling island city. In fear Corcyra appealed to Athens for help and swayed by the Corcyrain diplomats, the Athenians sent military aid. A battle took place, in which the navies of Corcyra and Athens fought against those of Corinth. Sparta, who was allied with Corinth and relied upon it as a source of income, saw the Athenian support of the Corcyrain rebels as an act of aggression against the peloponnesian league (Sparta and her allies). The alliance made between Athens and Corcyra was also viewed as a violation of the peace treaty of 445 B.C. between the peloponnesian league and the Athenian league. Athens ignored all Spartan protest about its involvement in the Corcyrain campaign. Further feud was created between Sparta and Athens in 432 B.C. in Potidaea. Potidaea was a city that was tributary to Athens but Co rinthian in blood. Tired of paying tribute to Athens the citizens of Potidaea attempted to expel the Athenian power. Athens’ soldiers besieged the city and once again Athenians were battling Corinthians. Corinth, aiding the people of Potidaea faced an embargo by Athens. Enraged by this act Sparta appealed the Athenians to end the embargo, but was ignored. Sparta conviened the peloponnesian council and Greece moved one step closer to the peloponnesian war. It could be argued that Sparta and Athens were already preparing for war with each other and that the support of their allies’ wars against each other was not a direct cause of the war but si... ...led to a natural distrust between the two cultures. Pericles, the Athenian ruler before and during the Peloponessian war once compared the â€Å"living force of Athenian freedom with the dead hand of Spartan tyranny†. Thucydides once quoted a Spartan describing the Athenians; â€Å" The Athenians are addicted to innovation, and their designs are characterized by swiftness alike in conception and execution; you have a genius for keeping what you have got, accompanies by a total want of invention, and when forced to act you never go far enough. Again they are adventurous beyond their power, and daring beyond their judgement †¦Ã¢â‚¬  These two quotes show a clear dislike between the two peoples. The two superpowers, so different in culture could not avoid conflict, conflict that eventually resulted in the peloponnesian war.   Ã‚  Ã‚  Ã‚  Ã‚  The roots of the peloponessian war can be traced back to many specific instances but on the most part three main elements caused its rise; Sparta’s anger at Athenian aid to Spartan enemies, Spartan fear of Athenian power, and the hostility and mistrust caused by the radical differences between the two societies. The peloponnesian war was inevitable.
