Applications of Radioactivity in Medicine

Applications of Radioactivity in Medicine Introduction A radioactive element is an element with an unstable nucleus, which radiates alpha, beta or gamma radiation and gets converted to a stable element. Both radioisotopes and enriched stable isotopes are essential to a wide variety of applications in medicine, where they are used in the diagnosis and treatment of illnesses. In addition, extensive applications of isotopes in biomedical research finds wide parallel uses in research chemistry, physics, biology and geosciences, with additional needs existing in the commercial sector. HISTORY Radioactivity arrived on the scene of the world in the 19th century, just when people thought they knew everything in science. With its discovery in 1896, radioactivity opened a box of many questions and revealed a new world, waiting to be explored in the microcosm of the atomic nucleus. Radioactivity also helped in answering the questions which were not yet known. This helped science in many fields. WHAT MAKES AN ELEMENT RADIOACTIVE? There are three kinds of particles inside an atom: that is protons, neutrons and electrons. The nucleus contains the above mentioned two particles i.e. protons and neutrons. The region beyond the nucleus contains electrons that balance out the charge of the protons. The number of protons is equal to the number of neutrons that is why the atomic weight is twice the atomic number. Since like charges repel each other which results a force that tries to push the electrons and protons apart. If the ratio of protons to the neutrons is not within certain limits then the proton can not be held firmly together which leads to the formation of an unstable nucleus. Making the isotopes of some elements radioactive. For example, carbon, the element found in all living things has a chemical symbol C. the normal form has an atomic weight of 12 and is written as carbon-12, but the radioactive version has two extra neutrons, so the symbol iscarbon-14. As we shall see, the radioactive form behaves chemically just like the non-radioactive form, although one shall never change into the other. There are three kinds of radioactivity each with different radiation type. RADIOACTIVITY Radioactivity is a very interesting phenomenon in nature. Classical Electromagnetism cannot explain radioactivity. Its a spontaneous and random phenomenon whereby nuclei of certain chemical elements like Uranium, radiate gamma rays, beta particles and alpha particles. By the emission of these particles and radiation, the unstable nucleus gets converted into a stable nucleus. This is called RADIOACTIVE DECAY. Radioactivity was accidentally discovered by HENRI BECQUEREL. Scientists like Madam Curie and her husband Pierre also worked hard to isolate other radioactive elements such as Polonium and Radium. Knowledge of radioactivity helped scientists to work out the structures of atoms. USES OF RADIOACTIVITY We could not do without radioactive materials in todays world, even if we wanted to. We rely on these radioactive elements every day to make us healthier, to help supply necessities like food and electricity, keep us safer, help us to protect our environment, add fun and convenience to our lives and help us learn more about our world. Radioisotopes have found a large number of applications. Some of them are as follows: Medical Diagnosis Generate Electricity Synthesis of new elements Preservation of food Smoke detectors and many more RADIOACTIVITY IN MEDICINE Ionizing radiations has many beneficial uses as they can be used for the diagnosis and for the curing of many diseases. Since infected cells can be killed by these radiations. Hence they are widely used in caner treatments. Radioactive isotopes are commonly used in medicine, which help the physicians to know more about the body structures. For the treatment of cancers radioisotopes are commonly used which require destruction of harmful cells causing these type of diseases. Although nuclear medicine started its clinical origin in the 1930 decade, the invention of gamma scintillation camera by an American engineer Hal Anger in the mid of 1950s, though, this invention brought an important turn back in medicine imaging Radioactive isotopes also allow excellent quality imaging of bones, heart, liver and many parts of our body. Gamma ray emitted tracers are used in large number of diagnostic procedures in nuclear medicine. These traces are formed due to the bonding of radioisotopes having short life period with chemical compounds that allow the targeting of a particular body regions or physiologic processes. Emitted gamma rays can be detected by gamma cameras and computer enhancement of the resulting images allows quick and relatively non-invasive assessments of trauma or physiological impairments. CANCER which is a process of rapid growth of cells gets damaged by radio isotopic radiations. Somehow, some cancerous growth of cells can be eliminated or restricted by the use of radioisotope radiations. The most common forms of external radiations therapy is use of the gamma radiations and X-rays. During the last half of the twentieth century the radioisotope Cobalt-60 was most commonly used source of radiation used in such treatments. Today thousands of hospitals all over the world use radioisotopes in medicine, and about 90% of the procedures are used for diagnosis. Technetium-99 is the most common isotope used in diagnosis, with some 30 million procedures in a year, accounting for 80% of all nuclear medicine procedures all over the world. ISOTOPS COMMONLY USED IN MEDICINE: There are about 20 radioactive isotopes used in medicine. Each isotope has its own use in this field. Some of them are: Chromium-51, cobalt 60, Erbium 169, Iodine-125, Iridium-192, Sodium-24, Xenon-133, Selenium-75, Strontium-89, Phosphorus-32 etc. Here is a list of isotopes with there half life period and uses: Chromium-51: Half life period 28 days Purpose: Used to label red blood cells and quantify gastro- intestinal protein loss. Cobalt-60: Half life period is 10.5 months Purpose: Formerly used for external beam radiotherapy. Erbium-169 Half life period is 9.4 days Purpose: Use for relieving arthritis pain in synovial joints. Iodine-125 Half life period is 60 days Purpose: Used in cancer Brach therapy (prostate and brain), also diagnostically to evaluate the filtration rate of kidneys and to diagnose deep vein thrombosis in the leg. It is also widely used in radioimmunology- assays to show the presence of hormones in tiny quantities. Iodine-131 Half life period is 8 days Purpose: Widely used in treating thyroid cancer and in imaging the thyroid; also in diagnosis of abnormal liver function, renal (kidney) blood flow and urinary tract obstruction. A strong gamma emitter, but used for beta therapy. Iodine used for curing thyroid cancer Iridium-192 half life period is 74 days Purpose: Supplied in wire form for use as an internal radiotherapy source for cancer treatment (used then removed). Sodium-24 Half life period is 15 hours Purpose: For studies of electrolytes within the body. Xenon-133 Half life period is 5 days Purpose: Used for pulmonary (lung) ventilation studies. Phosphorus-32 Half life period is14 days Purpose: Used in the treatment of polycythemia Vera (excess red blood cells). Beta emitter. X-Rays are used to examine the internal parts of the body that is bones to see the fractures. Applications of X-Rays: Radiography: Radiography is used to diagnose the ailment and diseases of the internal and hidden parts of the body using x-rays. Fluoroscopy: Fluoroscopy is a type of medical imaging that shows a continuous x-ray image on a monitor. Digital Subtraction Angiography: Digital Subtraction Angiography (DSA) is used to image blood vessels. Computerized Axial Tomography: A computerized axial tomography scan is an x-ray procedure that combines many x-ray images with the aid of a computer to generate cross-sectional views and, if needed, three-dimensional images of the internal organs and structures of the body. Mammography: Mammography is a special type of x-ray that is used for the detailed images of breast. Radiation Therapy: Radiation therapy (also called radiotherapy), high-energy rays are used to damage cancer cells and stop them from growing and dividing. A specialist in radiation therapy is called a radiation oncologist. Uses of Radioactive Materials in Medical Research Used in Biomedical researches: The Radioactive isotopic materials are very essential in curing many dreadful diseases like AIDS, cancer and Alzheimers disease. In Pharmaceutical drug testing: The U.N. Food and Drug Administration require all new pharmaceutical drugs to be tested for safety and effectiveness. More than about 80 percent of those drugs are tested with radioactive materials. One of the most important tests is to determine if the pharmaceutical is going to the other parts of the body than the desired or intended target and what effect it can cause to the parts where it is not needed. By adding a radioactive tag to the pharmaceutical, researchers can pinpoint all the parts of the body and the concentration that accumulates non-targeted areas. From this they can determine if there is likelihood of adverse reactions in other parts of the body. Metabolic Research: Radionuclide is used extensively in metabolic studies and genetic engineering. Chemical Reaction Imaging: the latest single photon emission typography (SPET) on positron emission tomography (PET) enable scientists to watch colour images of chemical reactions in living tissue and, in particular, to trace opioid molecules- naturally occurring morphine-type drugs which eliminate pain within the brain. Side Effects of Radiation The form of the energies that are released from these elements in radiation therapy is often administered by machine. The machine aims those radiations at the cancer. Radioactive substances can also be kept inside the body of a person. These types of treatments can cause many side effects. These side effects may include: hair loss nausea vomiting swelling difficulty swallowing urinary and bladder changes The side effects caused due to the treatment of the patient can last long for a certain period of time. It may be a period of two months, six months or even a year. So the patient has to bear some pains after or during the curing of fatal diseases like cancer using radiation therapy. Radioactive Waste Disposal: An Environmental Perspective Any activities that produce or use radioactive materials generate radioactive wastes. Various processes in medicine, scientific result and in all other fields produce bi products that include radioactive wastes. Radioactive waste can be in gas, liquid or solid form, and its level of radioactivity can vary. The waste can remain radioactive for a few hours or several months or even hundred or thousands of years. Because it can be hazardous and can remain radioactive for so long, finding suitable disposal facilities for radioactive wastes is very difficult. Depending on the type of waste disposed, the disposal facility may need to contain radiations for a very long time. Proper disposal is essential to ensure protection of the health and safety of the public and quality of the air, soil and water supplies. Radioactivity waste disposal practices have changed substantially over the last twenty years. Evolving environmental protection considerations have provided the impetus to improve disposal technologies, and, in some cases, clean up facilities that are no longer in use. Designs for new disposal facilities and disposal methods must meet environmental protection and pollution prevention standards that are stricter than were foreseen at the beginning of the atomic age. CONCLUSION One hundred years ago, a group of scientists unknowingly ushered in the atomic age. Driven by curiosity, these men and women explored the nature and also the functioning of atom. Their work initiated the paths of research which changed our understanding of the building blocks of matter. There discoveries prepared the way for development of new methods and tools used to explore our origins, the functioning of our bodies both in sickness and health, and much more. How did our conceptions of atomic properties change? How has that change affected our lives and our knowledge of world? Radiation is a two edged sword: its usefulness in both medicine and anthropological and archaeological studies is undisputed, yet the same materials can be used for destruction. Human curiosity drove inquiring scientists to harness the power of an atom. Now humankind must accept the responsibility for the appropriate and beneficial uses of this very powerful tool.

Economic Networkingâ€Exploring Alternatives for Promoting Sustainable De

Economic Networking—Exploring Alternatives for Promoting Sustainable Development in Africa INTRODUCTION The history of European aid intervention in the African, Caribbean and Pacific (ACP) states has traditionally acted to reinforce the hierarchical distinction between the â€Å"developed† and the â€Å"developing† world. The series of Lome Conventions which granted preferential trade agreements between these groups of countries have proved ineffective in encouraging economic sustainability in the ACP states, and although the ACP includes most of the Least Developed Countries (LLDCs) in the world, the agreements have been criticized as being unfair in the global context. Under pressure to negotiate a new ACP-EU agreement that would be consistent with World Trade Organization (WTO) regulations, and improve on the limitations of the previous Lome Conventions, the Cotonou Convention was signed in 2000, after arduous negotiations. Despite this agreement, the future of ACP-EU relations is somewhat vague. Particularly with respect to Africa, this uncertainty leaves room for eva luation of the effectiveness of the past agreements and an objective analysis of the motives behind previous economic ties. Furthermore, by analyzing the problematic history of European aid to Africa, there emerges a basis for shifting away from the neo-colonialist relationships that characterized most of the past agreements, and exploring the benefits of creating alternative partnerships. Ultimately, the possibility of forming partnerships amongst individual ACP countries and between other developing countries is an overlooked idea that should be further explored.

Health and social care management Essay

INTRODUCTION This essay the author will be able to evaluate current systems for managing finances Resources in health and social care settings. Therefore will evaluate how financial Decisions are made and the need to monitor budgets. This will then enable the author to Evaluate the impact of financial considerations on an individual using health and Social care services. Furthermore will provide a core understanding of the range of systems available, and How these are used in the planning and financial management of health and social Care budgets. The unit further will encourage understanding the importance of Monitoring budget expenditure and its influence on the provision of health and social Care services. LO.1 1.1PRINCIPLE OF COSTING AND BUSINES CONTROL SYTEMS Analysis of current situation against budget and forecast, classification and coding, job costing, Contract costing, actual cost ascertainment,allocation/apportionment COSTING DEFINITION: Costing it describe as According official terminology the technique and procedure of ascertaining cost. These valuation systems including main beliefs and system to determine the cost of goods or services. It also the  quantity of supply used in replacement of goods or services. The income used can be financed or money’s value, Semi Variable Semi Fixed Cost Cost: Cost is an amount that has to be paid or given up in order to get something Cost Unit: The unit cost is the cost incurred by a company to produce, store and sell one unit of a particular product. Unit costs include all fixed costs and all variable costs A cost center is part of an organization that does not produce direct profit and adds to the cost of Running a company. Examples of cost centers include Cost object: Cost object is often a product or department for which cost is accumulated or measured. For example, a product is the cost object for direct materials, direct labor and manufacturing overhead also the factory maintenance department is cost object for the cost of the maintenance employees and the maintenance supplies. Cost benefit analysis: Is A cost object is a tangible input for a product manufactured/service provided, like labor or material. For example a cloth manufacturing firm requires some Break even analysis: Classification of cost means, the grouping of costs according to their common characteristics. The important Cost behavior The way a specific cost reacts to changes in activity levels is called cost behavior. Costs may stay the same or may change proportionately Variable Cost / Product Cost: Variable costs are the Fixed and Variable cost A cost is fixed if, within a specified period of time, it does not change in response to changes in the level of activity. A variable cost is one that changes in response to changes in the level of activity, it changes in direct proportion to the volume of activity, that is, doubling the level of activity will double the total variable cost total cost over a period of time for the variable inputs. Any increase in the volume of production results in an increase in the variable cost and vice versa. For example, of variable costs is the cost of raw material. Semi-Variable Cost / Semi-Fixed cost: These costs are in part fixed and in part variable. For example: repair machine fees. Semi-variable cost includes both a fixed and a variable element. For example, a telephone bill contains a fixed standing charge and  a variable charge based on the number of units dialled. A semi-fixed cost or stepped cost is one where the cost remains constant for a range of activity; then when the activity increases still further the cost will take a step upward. Break-even Analysis is an expected component of most business plans, especially for start-up companies. It shows how much revenue you need to cover for both fixed and variable costs and cost benefit analysis are frequently used by health and social care organisation to monitor cost and make decision about expenditures. Cost data are very useful in budget preparation and forecasting for the financial year, the Providers use cost data to manage services and improve operational efficiency. Cost data are also used to support the development of pricing and currency design for reimbursement purposes A direct cost is especially noticeable to a set cost object. A cost object is a product, procedure, section, or action for which the health administration requirements to assess the cost, such as a medical test, a care appointment, or a health check process. Indirect costs cannot be traced to an agreed cost purpose not including resorting to some arbitrary method of assignment. Hand, is directly involved in producing revenues, and, if it is managed well, its revenues exceed its cost and it produces a profit. The six principles of costing are: Stakeholder engagement: Stakeholder engagement is the process by which an organisation involves people who may be affected by the decision it makes or can influence the implementation of its decision Materiality : is in accounting relates to the significance of transaction, balances and errors contained in financial statements. . Consistency For some costing purposes, a consistent approach is required across or within organizations. Data accuracy, Accurate costing relies on the quality of the underlying input data. Transparency Costing should be transparent and auditable Causality and objectivity Importance of costing: Costing help an organisation to manage is company to incur a cost with the  expectation of profit Example: A company may have a variety of distinct departments,division,or operating groups,each with separate responsibilities and each contributing to the overall success of the company.cost centers,for example,such as accounting,auditing,or inventory control,have costs,but does not contribute revenues. As a result, they do not produce profits. 1.2 The information needed to manage financial resources Is to understand the role of planning in the management of health and social care budgets also the importance of monitoring budget expenditure.

The 1950s and the 1960s - 900 Words

The 1950s and the 1960s had many similarities, though they had many differences as well. Their similarities and differences include: the politics, the economy, the society, and the culture of both decades. In the 1950s, North Korea moved into South Korea and began a civil war between the two parallel countries. The reason for this dispute was the border lines as well as guerrilla fighting in the South, which created a greater tension on the issue. The reason why the U.S entered the Korean War was so that the Soviet Union would not gain another nation and, in turn, more power. Like the 50s, our country was also at war with another country in the 60s. This time, the U.S was at war with Vietnam.

Although Eisenhower was not a take charge kind of president, the country achieved a heightened level of prosperity. Economically, the 1950s were a pretty successful era. People had been saving their money through WW2 and they were ready to start buying houses, cars, etc. There was much inflation in the during the war, but it had quickly diminished as the years progressed. One of the issues that Eisenhower tried to address was to balance the federal budget of the nation. This was very difficult, especially since the families of the 50s were buying more and spending less with the use of credit cards. However, in the 1960s, prosperity was becoming too far out of reach. The Cold War and the Korean War were very costly in military spending. It had taken its toll on the economy. Even with more people buying, the economy was growing at a very slow rate. There were also millions of Americans who were still living in poverty, and the economy had gone into recession quite a few times in the 60s. Then, the stock market fell dramatically, the worst it had been since the Depression. Kennedy addressed this by making tax cuts for larger business, which helped the economy develop and grow more prosperous in the years to come.

Prior to this select time period America were fighting in the Cold War and many black soldiers battled in the name of ‘freedom’. This was ironic as these black soldiers were fighting for something that they didn’t even have back home. Often Black soldiers talked about the ‘Double V Campaign’;

Building Envelope - 9025 Words

Introduction The Building Envelope is the area that separates conditioned space from unconditioned space or the outdoors. A building envelope includes all elements of a building that enclose conditioned space. Building envelope components separate conditioned spaces from unconditioned spaces or from outside air. For example, walls and doors between living areas are part of the building envelope; walls separating a garage from the living areas are not. Besides that, floors of conditioned basements and foundation are technically part of the building envelope. Roof and ceiling also can consider as building envelope. You can think of the building envelope as the boundary separating the inside from the outside and through which heat is†¦show more content†¦The piles are then interconnected with a rigid system of strip-raft to ensure uniform settlement profile and distribution of loads. The stability of this foundation is able use to resist seismic matter. And, this foundation has been used in Georgia country and proved that this foundation is strong enough to resist seismic matter. Traditionally, piles are the common way to issue the bearing capacity and excessive differential settlement. Piles are often installed until to the desired stratum that able to support the entire loads from the piles. But, piled foundation on soft ground is not an ideal way because reduction of pile capacity is predicted to happen with time due to negative skin friction and associated voids formation and settlement problems under the ground floor slab due to long-term settlement. A simple way to explain that is a big raft or slab is constructed as a foundation. When raft foundation has become a â€Å"bowl† shape, this means that defection of the building is occurred. The defection on any part of the structural members will cause the unstable of the overall system and thus will lead to collapse, the worst case. Sometimes, geotechnical engineering is also involved in design of the foundation as the information from the borehole investigation is crucial. The pile for the use in piled raft foundation can change due to the superstructure above the ground. The pile types can be barratte or bored piles and etc. There areShow MoreRelatedWhy Building A Building Envelope Design Is Important At All The Levels Of Construction1381 Words   |  6 Pagesfor better and more sophisticated envelope buildings will continue to be important at all the levels of construction.

Research Portfolio To Understand Issues †MyAssignmenthelp.com

Question: Discuss about the Research Portfolio To Understand Issues. Answer: Introduction: An attempt has been made to research on the institutional management and various key points regarding the same have been discussed in this research portfolio. Certain case studies have also included in the research portfolio to understand all the issues and risks regarding the same. It was assumed that all the skills that are needed to run an institution should be carried out by the staff of the institution (Weinstein Wild, 2016). Certain research propagations have been adopted by thelaw universities of United States regarding certain research topics and it has been presumed by the authority that the student must know the basic research skills or has the power to adapt the skills through their courses. However, it was observed that the students have the laxity regarding the research skills and that leads all thelaw universities to start up program relating to the development of research skills to decrease the potential risks regarding the research skills (McNeil, Frey Embrechts, 20 15). With this intention, many of thelaw schools have added a training program regarding the issue and the training materials have assisted the students to understand the base of the referencing workshops and research workshops as a whole. A similar model has been followed up in our institution and at the present time, I am able to differentiate between the relevancy of journals, books, articles and legal cases. During the training course, it has been taught to us that in case of any legal research, the sources are generally based on the Articles, books, journals and certain government websites. Certain techniques are to be followed to write down a project report. Before getting into the main topic, it is important to understand the objective of the research portfolio. Through this type of portfolio, a number of projects are to be done. It has been taught to us that a legal research is based on summaries of statutes and cases. The legal researches are also getting its sources from the forum postings, blogs and news papers. It has been observed that referencing sometimes cause great dilemma regarding the research proposal and it must be encountered with great effort and care (Chance Brooks, 2015). However, I did not face any kind of dilemma regarding the same and I try my best to follow up the rules regarding the same. Reflection and Comment on case study: In this research portfolio, we are going to discuss certain aspects of the case study based on thelaw and impacts of the price fixing system. It has been stated that certain strategies are taken or adopted to deal with the problem. However, before getting into the periphery of the main subject, it is important to do certain background study that will help us to understand the main objective of the case and that may help to encounter the price fixing problems (Sadgrove, 2016). It is to be understood the definition and character of a case study and it is also to be realising the importance of it. A case study helps the researchers to understand the scope of the relevant subject and help to make the decision in such situation that may be cropped up in future. In the present situation, I have chosen price fixing problems that affects the airlines business in recent times and it is required to counter the same to avoid the detrimental consequence, it has been observed through the study is that many international cargo and airlines companies are involved in the price fixing problems. It has also been observed that many international airlines companies are enlisted in this case and suspected to commit fraud by way of fixing prices (Homsombat, Lei Fu, 2014). It has been observed that certain institutions have pointed out the facts that the airlines companies are intervened the public policies and the level of surcharges are also violate the provisions of the consumers protection laws. An initiative has been made by me to define the relevant points like the price fixing or the airlines industries. Certain allegations are made against the airlines companies like Lufthansa Cargo and Qantas airlines regarding fuel and security surcharges. The pro blem in my case is based on the airlines problems in the provinces of Australia. A commission is being responsible for the inspection regarding the same namely Australian Competition Consumer Commission. The Act that deals with the following problem is Competition Act 1998 and it has been alleged that the airline companies had adopted certain policies to increase the surcharges with an intention to create illegal competitive activities. The whole racket was involved other countries like New Zealand, Indonesia and Singapore airlines. Reflection and Comment on other case study: In the other case study, an attempt has been made to understand various legal grounds relating to bullying in the workplaces and certain educational institutions. In this case, certain definitions have been made to ease the topic to understand the outcome of the same. Bullying means certain gestures or words to make someone feel bad and the main objective of such act is to humiliating others. It is a form of abuse that can be seen in workplaces and other educational institutions (Eller Moreira, 2014). The word trolling is a part of bullying that forms by way of publishing posts and memes with an intention to humiliating others. In recent days, it has been observed that the amount of humiliation through bullying has increased in a tremendous way and in this case law, an attempt has been made to point out the scopes and types of bullying so as to prevent the detrimental outcome. In case of educational institutions, bullying are observed through cyber bullying and trolling and fatefully the cyber cafes are becoming the epidemic centre for all this bullying. It has been observed from many reports that the almost 40% children in Australia are victimised by this in school session. Almost in every year, many people are died by this bullying and trolling in Australia. Reflection and Comments on legal risk, rules, and management Therefore, from the above mentioned cases, it has been observed that the subject matter of the cases is serious in nature and harmful to the society as a whole. There are certain legal risks present in case where the interest of the society is attached in it. Certain legal management are to be followed to overcome the public liability and foreseeable harm in this case. In case of the former case study, the price fixing policies taken by the airlines companies are affecting the international relationship and certain laws were enacted to counter the offence in a systematic way (Peppard Ward, 2016). The illegality regarding the price fixing has been mentioned under section 48 of the Competition Law and the Consumer Law as the policy has affected the consumers as well. Australian Competition Consumers Commission has imposed with the power to take action against the alleged airlines companies. Section 48 of the said Act restricted the companies or corporations to be engaged into such pr actice. Legal actions has also been taken against New Zealand airways as the company was alleged to make an agreement with other air companies to fix up the fuel surcharge and the court impose injunctive relief and pecuniary penalties on the company. Allegations have also been made against certain leading companies like Qantas airlines and Lufthansa cargo and each of these companies have to face serious fine regarding the same. In the other case, there are also certain legal risks present that can be pointed out in a systematic manner and in this case, similar attempt has been made. Keeping in mind the detrimental effect of the bullying in workplaces and other educational institutions, the Australian government has stated the process as crime. In this case also, certain Acts were enacted to consider the following situations. One of such Act is OHS Act. The acts regarding bullying are treated as a discriminatory act that is harmful for the interest of a person and the society as well (Barkan, Bintliff Whisner, 2015). Therefore, it becomes necessary to prevent these crimes and legal actions are being made by the government in relevant cases (Grant, 2016). The government of Queensland has taken certain policies to curb this social crime and an attempt has been made to find out the symptoms of this crime. The government has tried to promote the awareness programs by adopting certain anti-bullying policies. Att empts have also been made to reduce the harassment and eradicate the process from the society. Impacts of the cases: There are certain impacts of these crimes have been made on the respective industries and society as well. It is a well known fact that many classes of people are involved in the airlines business and they continue their livelihood on the profession (Whyte Lohmann, 2015). However, they have to face serious problems if the airlines companies are fixed and maintained the prices regarding the fuel or security surcharges. Consumers are also affected by this process when the prices are being fixed by the companies in case of transporting certain materials by freight. It affects the supply chain tremendously and the price of the goods is being increased in this process. On the other hand, the bullying process impacts on the society and as per many reports, the victims of this offence had committed suicide. Therefore, it can be stated that the implications of this offence had made a serious question in the workplaces and the future of the same and that should be optimised with great care and skills by the concerned governments. Difficulties faced in enforcing laws: In Australia, the governmental structure is federal in nature and the policy taken by the governments are varying from one province to another. Therefore, it becomes difficult to bind the airlines companies within one statutory limitation (Gall, Gall Borg, 2014). The companies are engaging themselves in international base and it has created serious problem regarding the implementations of law. It is true that the Australian Competition Consumer Commissions are effectively taking policies regarding the same and the Federal courts are also imposing penalties on the alleged companies but the quantity of the penalties are based on the levels of co-operation and dilemma has to be faced when the cases are withdrawn regarding the enactment of different laws (Herr Anderson, 2014). I have learned certain important lessons regarding the subject matters of both the case laws and the legal management involves in this process. I have come through the policies of the government regarding the same and it has been observed by me that the implications and the dilemmas regarding the problem and the detrimental effect of the policies as well.

This book is an important creation to denote the price fixing system by the airlines companies and the effect of the same in the portion of the society. The book is also useful for the case study as it addresses how the Australian Law has enacted certain grounds to deal with the problem and through this book, an outcome regarding the problem can be possible. The book also addresses issues such as impact of the fixing policies on the society, problems regarding the same, and legal steps to deals with the problem. Carlton, Dennis W., Robert H.
