Oxygen and Trees Essay Example for Free

Oxygen and Trees Essay Trees alter the environment in which we live by moderating climate, improving air quality, conserving water, and harboring wildlife. Climate control is obtained by moderating the effects of sun, wind, and rain. Radiant energy from the sun is absorbed or deflected by leaves on deciduous trees in the summer and is only filtered by branches of deciduous trees in winter. We are cooler when we stand in the shade of trees and are not exposed to direct sunlight. In winter, we value the sun’s radiant energy. Therefore, we should plant only small or deciduous trees on the south side of homes. Wind speed and direction can be affected by trees. The more compact the foliage on the tree or group of trees, the greater the influence of the windbreak. The downward fall of rain, sleet, and hail is initially absorbed or deflected by trees, which provides some protection for people, pets, and buildings. Trees intercept water, store some of it, and reduce storm runoff and the possibility of flooding. Dew and frost are less common under trees because less radiant energy is released from the soil in those areas at night. Temperature in the vicinity of trees is cooler than that away from trees. The larger the tree, the greater the cooling. By using trees in the cities, we are able to moderate the heat-island effect caused by pavement and buildings in commercial areas. Air quality can be improved through the use of trees, shrubs, and turf. Leaves filter the air we breathe by removing dust and other particulates. Rain then washes the pollutants to the ground. Leaves absorb carbon dioxide from the air to form carbohydrates that are used in the plant’s structure and function. In this process, leaves also absorb other air pollutants—such as ozone, carbon monoxide, and sulfur dioxide—and give off oxygen. By planting trees and shrubs, we return to a more natural, less artificial environment. Birds and other wildlife are attracted to the area. The natural cycles of plant growth, reproduction, and decomposition are again present, both above and below ground. Natural harmony is restored to the urban environment.

Calculating Blood Components of Cholesterol Research Design

Calculating Blood Components of Cholesterol Research Design Good health is absolutely important to a human being and to remain healthy people need to check their blood level parameters. Cholesterol is a very important constituent of over100 constituents in human blood. It is important to develop an instrument wherein blood parameters can be calculated which will be non-invasive, user friendly, portable and reliable. The thesis explains the designing and making of an instrumentation setup to calculate the blood constituents. It comprises of the study of samples made in the laboratory according to the various constituents present in whole blood in the RF range of 10MHz-4000MHz. The data is later fed to a regression analysis matrix which can be programmed in VLSI chips such as Altera FPGA in order to calculate the constituent concentration. This thesis is proposed to contain 6 chapters with proposed chapters as given below Chapter I (Introduction) This chapter includes the introduction to the thesis, health and diseases, overview of cholesterol, types of cholesterol, role of cholesterol in humans, the various diseases due to high cholesterol, the worldwide scenario, the testing of cholesterol blood test range of different constituents. Total mental, physical social wellness is a condition of health as well as the presence of infirmities or diseases.[1][2][3] Good health is often marred by diseases and illnesses which are sometimes incurable.[4][5] The most dreaded diseases include Cardio Vascular Diseases (CVD) and Strokes due to high Cholesterol. About 7,000,000 persons die of heart disorders annually in the world, of which 2,400,000 are Indians. Strokes are the next principal source of death at 6,200,000 of which 1,600,000 are Indians. Cholesterol is important for normal body functioning, which appears to be a fat-like material which is waxy in nature. It is used in making of hormones and for cellular functions. The Total Cholesterol (TC) in the blood consists of High Density Lipoprotein (HDL), Low Density Lipoprotein (LDL) triglycerides. The cholesterol obstructs the arteries when it amasses in the body resulting in the limitation of blood flow. It could be tested invasively by visiting a doctor extracting the blood using a needle syringe technique. Since this procedure is painful, it develops a fear among the patients could also be infection prone. Non-invasive methods are easier to use in one’s home. Instant report could be attained therefore non-invasive technique is gaining a lot of importance as the electronics industry now offers many smart sensors. Blood has many constituents and it depends on aspects such as age, diet, state of health and other particulars.[6][7][8] The chief blood components are Cholesterol, NaCl, Glucose, Urea, Lactate Alanine. There are quite a few number ways to compute blood cholesterol in humans, invasive non-invasive. They can be categorised into chemical tests and physical tests. The significant ones are based on Photo Acoustic Spectroscopy (PAS), Stimulated Emission spectroscopy, Thermal Emission Spectroscopy (TES), Optical absorption spectroscopy, Liquid Chromatography method, Chemical Method, Ultracentrifugation, Electrophoresis and Impedance measurement. The important techniques together with their working principles and the merits demerits are discussed below. Near Infrared Spectroscopy (NIRS): The principle of NIRS is that constituents absorb Infrared light at their characteristic wavelength. The absorption level is comparative to the constituents present. Hence the contents present can be predicted. It uses a physical rather than a chemical technique. It is rather sensitive to calibration errors, but probes for non-invasive measurement are not available. However, new spectroscopic methods are now available with IR optical fiber for guiding the light to the tissue. Chemical Method: In order to determine plasma cholesterol, the chemical procedure of Abell-Kendall is done which comprises of the Liebermann-Burchardt response after hydrolysis and eradication of cholesterol. Plasma cholesterol triglyceride content determinations are usually examined by computerized techniques at clinical research facilities. Default values for plasma TC are achieved using autoanalyzer frameworks to which either the Liebermann-Burchardt test or the ferric chloride–sulfuric acid technique could be applied. A fluorometric investigation is utilized to decide the triglyceride reference values. Basic plasma estimations of triglycerides and TC can be relied on for the analysis of the diverse lipoprotein issues. It is an invasive method and there is wastage of chemicals in testing. Chromatography: Chromatography techniques can be sorted out into 2 categories, i.e. Gas chromatography (GC) and Liquid Chromatography(LC). GC is a typical kind of chromatography utilized scientifically for dividing and analyzing constituents that can be vaporized without decay. GC is used to test the purity of a specific substance, or segregating the distinctive parts of a mixture. In High Performance Liquid Chromatography (HPLC), a mobile phase comprises of either polar or non polar solvents. The specimen is constrained by a fluid at a huge pressure through a section that is filled with a stationary phase for the most part made out of sporadically or roundly formed particles picked or derivatized to achieve specific sorts of separations. Chromatography has low uncertainty, high precision, high accuracy and good linearity but it is expensive and not portable. Impedance Measurement: An Impedance Plethysmograph framework is made up of a V-I converter and a sine generator. Passing current into a body section is done with the assistance of two current electrodes. The current path which produces the voltage signal is sensed with the assistance of an alternate pair of voltage electrodes.[9][10] The impedance is correlated to the amplitude of the signal. Impedance qualities measured at a series of frequencies or at a few distinct frequencies may aid in clarifying the differences in body composition more accurately than impedance estimation at a specific frequency.[11][12] Chapter II (Objectives Literature Review) Mas S. Mohktar et al recommended a method to estimate the cholesterol level in blood utilizing neural network bioimpedance techniques non-invasively. Bioelectrical Impedance Analysis (BIA) estimation was executed utilizing the bio impedance analyzer, Biodynamic Model 450. A current signal [13] E. Aristovich et al recommended a non-invasive impedance technique estimation of blood cholesterol by 3D finite field modelling. This process supports the variation of calculating impedance over a conducting medium since the concentration of particles is altered. To calculate impedance, the current is computed between 2 electrodes throughout the conducting media created by the electric field distribution. It is obtained by computing modelling 3D electric fields for known voltages connected between the electrodes utilizing Finite Element Method (FEM). The intricacy of FE models is accredited to particle distribution, the material geometrical parameters, and the size shape that can be of several orders of degrees lesser as when compared to the general problem domain under investigation. The paper prevails over the setback by implementing a useful particle aggregation technique in FE modelling exclusively influencing the accurateness of the field calculation. [14] J. Nystrà ¶m et al proposed to study a set of 34 men with various degrees of diabetic levels, including Multi Frequency (MF) BIA and skin changes by NIR. A fiber-optic probe to measure skin reflectance spectra was used on 4 sites. A joint multivariate analysis was carried out on the spectral range of 400-2500nm, using a lead sulphide detector (1100nm-2500nm) and a silicon detector (400nm-1100nm). NIR method can recognize skin conditions identified with diabetes. The 2 procedures combined together can offer a higher possibility for discrimination classification of skin condition with exact classification rising from 63% to 85%. [15] K. Cheng et al proposed to design a current source which includes a voltage controlled current source (VCCS), a microcontroller (uC) and a waveform generator (WG). The uC is made use of to program the WG to produce a sine voltage signal from 100 Hz 100 kHz. The VCCS based Howland current pump converts the signal to current. The total harmonic distortions of the o/p current are 0.25% at 1 kHz 0.40% at 100 kHz for the load resistance of 1 kà ¢Ã¢â‚¬Å¾Ã‚ ¦. The output currents phase difference varies from 0 ° to 19.6 ° over the above mentioned frequency range. The proposed multi-frequency BI measuring system provides an inexpensive solution for BI applications. During system testing, the output current signal is constant. Hiroshi Shiigi Hiroaki Matsumoto et al proposed a simple non-invasive technique to measure cholesterol by using a solvent to extract the skin component. A self-assembled monolayer (SAM) sensor and a HPLC were utilized to analyze the extracted solution. The SAM electrode having an excellent responsiveness sensitivity, attributed to its strong attraction towards hydrophobic cholesterol. Higher cholesterol was shown by the person with high cholesterol of the skin. The coefficient of correlation of non-invasive invasive method was 0.9408, hence this method could be used practically.[17] M.V. Malahov et al recommended to recognize hematological biochemical blood parameters that can be precisely estimated by means of BI technique. Samples of blood from 46 people were poured into four test tubes. Blood (2.5ml) was put in test tubes with Ethylenediaminetetraacetic acid for hematological investigation, next blood (3ml) was collected in tubes having heparin for BIA, later blood (2ml) was collected in tubes having sodium citrate for fibrinogen estimation and finally blood (4ml) was collected into unfilled tubes for biochemical serum examination. BIA analyzer à Ã‚ BC-01 Medass was utilized to perform BI spectroscopy of blood (1.5ml) from 5–500 kHz. Results show that the principle extracellular plasma particles: Na+ Cl concentrations are not related to extracellular fluid resistance of the blood. [18] Objectives The objective of the research is to design and develop an easy method to measure the level of cholesterol. The work envisages a development of an instrumentation using advanced microelectronics circuits, which is programmable and having interpretation mechanism to enable a common man to know his level of cholesterol. It is proposed to use multivariate system approach to enhance cholesterol signature in DSP domain. Chapter III (Methodology and Instrumentation) This chapter gives elaborate details on the preparation of samples, designing of cell, experimental setup and the instruments used. Human blood consists of many constituents; the major ones are Cholesterol (225mg/dL), Glucose (70-110mg/dL), Urea (10-20mg/dL), Lactate (10-15mg/dL) and Alanine (10-20mg/dL). Experiments are conducted with the above constituents. Samples are prepared using 14 mL distilled water, 1mL alcohol and the above constituents in varied concentrations. The average concentration is denoted as ‘1’, half the average is denoted as ‘0.5’ and approximately ‘0.75’ to ‘1.25’ is the actual range of blood components. The experiments are conducted with various concentrations as well, which are over the standard range for extreme cases, are denoted as 1.5, 1.75 2, 2.25 3. A cell was designed which was rectangular in shape having dimensions 12.5cms x 1cm x 2cms. The cell was used to measure RF response of various blood constituents. The cell was lined with a thin Cu foil and a copper wire was connected to 2 connectors which were placed on extreme ends of the cell. The external radiations were reduced by placing the cell in an iron box which was earthed. This forms the dielectric loss cell. The cell was then connected via RF cables to the tracking generator and signal analyzer. The entire setup was secured firmly avoid mechanical movements. Experiments were carried out using the slow sweep and the fast sweep. The experiment was conducted after an hour and 24 hours to verify the accurateness of the results. In comparison to the initial results, these were precise. The tracking generator used is Signal Hound USB-TG44A which ranges from 10 Hz 4400 MHz and the signal analyzer used is Signal Hound USB-SA44B which ranges from 1 Hz 4400 MHz. A separate power supply is not essential as it is fed from the USB cable. The tracking generator and signal analyzer are approximately 8† long, light in weight and could be used practically anywhere. Chapter IV (FPGA for Non-Invasive Cholesterol Measurement) Software and hardware components operating together to perform a definite application is called Embedded Systems. The hardware platform comprises of an i/p device, an o/p display, a microcontroller (uC) / microprocessor (uP), application software and an onboard memory. Designing embedded systems is getting more complicated nowadays due to the stiff restraints on power consumption, performance, size area usage. Hence, the software/hardware co-design procedure is utilized to plan embedded systems to decrease the measure of time used on debugging development. uPs whose behaviour architecture are completely described utilizing a subset of an Hardware Description Language (HDL) are called soft-core processors. They can be synthesized for any Field Programmable Gate Array (FPGA) or Application Specific Intergrated Circuit (ASIC) technology; hence they supply designers with much flexibility. A platform for combining multiple design functions into a package or a group of packages is provided by an FPGA device. Incorporation of functionality results in reduced power higher performances. Design combination can be accomplished by integrating soft or hard processor cores in an FPGA to execute processing functionality and required control. The capability to incorporate design functionality and system-level components can reduce schedule, cost and risk. Nios II Altera Organization Altera Organization is a top seller of FPGAs and Programmable Logic Devices (PLDs). They proffer the Cyclone, Stratix and Stratix II groups of FPGAs and are extensively utilized in DSP applications and design of embedded systems. Nios II Processor being a Reduced Instruction Set Computer (RISC) processor depicts Harvard memory architecture. The various features of this processor are single-instruction 3232 divide and multiply operations, instructions for 128-bit 64-bit multiplication, 32-bit Instruction Set Architecture (ISA) 32 general purpose registers. Chapter V (Multivariate Data Analysis) This chapter describes the multivariate data analysis, Partial Least Square Regression (PLSR), the different algorithms, i.e. Non-linear Iterative PArtial Least Square (NIPALS) and SIMple Partial Least Square (SIMPLS), the advantages and disadvantages of the algorithms, the ParLes software which is priority software developed for research applications, used for calculating unknown constituents. Nowadays several factors add to numerous problems which are multivariate. Multivariate analysis is a tool to obtain relationships and patterns amongst several variables concurrently. It can predict how an alteration in one variable affects other variables. It is very graphical which allows an analyst to observe the inner or unknown structure of big data sets and to visually recognize the factors which influence the outcome. PLSR is a bilinear form of technique where information in x data is assigned onto a small amount of latent variables known as PLSR components. The y data that are used in predicting the underlying variables to guarantee the first components are those that are most applicable for calculating the y variables. The relationship betweenxandydata is simplified as it is focussed on the minimum probable number of constituents. Chapter VI (Results Conclusions) This chapter includes the results and conclusions and the future direction of research. The multi-frequency BI spectrum was modelled through curve-fitting and multivariate statistical applications to extend parameters to predict body constituents like Cholesterol, Glucose, Salt, Urea, Alanine Lactate. The various components were mixed in different ways and some were used in the calibration file and the rest were treated as unknown. The spectra of cholesterol in different concentrations of 0.5, 1, 2 3 in the RF range of 10MHz to 4GHz was shown in Fig. 1. The cholesterol shows a good variation only in certain regions at specific frequencies (575 MHz, 995 MHz, 1145 MHz, 1285 MHz 2185 MHz) and one of them i.e. 575 MHz is shown in an expanded form in Fig. 2. The data obtained from the graph is then used in a calibration set to determine the unknown constituents presents in the blood. When the calibration set has more than 20 samples, it shows that it has less error. Since the spectra of every blood constituent are unique, the data of the spectra is fed to a ParLes software to get out unknown values of blood constituents. Table I gives the actual concentration of blood constituents in the experiment. Unknown concentration of cholesterol and known concentration of others were fed to a multivariate system. Table II shows the results of predicted values of cholesterol which are 43.75mg and 48.75mg whereas the actual values of cholesterol are 42.5mg and 51mg respectively. The results attained are within +/- 5% of the actual content in the sample are within the limits of the percentage error defined by WHO.

Packaging for the new product Essay -- Design and Technology

Packaging for the new product Packaging is vital, as goods need to be transported to the consumer in a safe, hygienic and protected condition. For instance putting tin foil round a kitkat, nestle product, keeps the bar fresh and prevents deterioration, instant coffee tends to be sold in jars to prevent spillage and because glass is a strong material, Nescafe Espresso roast is sold with ‘click lock closure’, which makes the jar easy to open. Additional packaging may be needed to assist retailers store the products easily and safety on the shelves. Packaging is essential to inform the customer about the contents, ingredients, weight, care instructions, etc. Some of which are legal requirements. Good packaging is an important part of the product. The basic function of packaging has always been to protect and contain a product. In a competitive market, branding and packaging are important and have become an integral part of the product. We instantly recognise products by the size, shape and colour of packaging. Packaging may be used by the manufactures to promote the goods, as the colour, design or lettering may make the product more attractive and noticeable to certain consumer on the shelf. Packaging is not just a safety attribute, different features are added to packaging to attract different segments, for example a children’s crisp might have colourful cartoons, entries to competitions or even a mini game on back of the packet. These types of product...

The Assault: Part 1: Search For Victory :: essays research papers

I am a normal kid, well sort of. Everyone has those different things about them, for example: I fly planes, fence, and can perform geometry in my head. I am also a good shot with almost any type of gun. I am one of the best strategists in my school. Troon High School, the high school of Troon a town just north of Corpus Christi, Texas is one of the only schools in the state to have a fencing team. We have been the highest rated one in the state only the year I have been here. I am the second best, the best being another 9th grader, Drew Davis. Now, it's time to get to the story.I blocked a downward slash, then gave a weak thrust, mostly to give myself time to regain my balance. He moved back about two paces, I had gained ground. He still had one advantage over me, height. He always won using attacks from above. This match had been going on for about ten minutes, a very long time. The next thing he did surprised me, jumping high in the air; his foot came up and kicked my sword out of my hand. He thrust at me, but missed due to a backward flip on my part. As soon as I landed, I tried to kick his sword away, but his blade found the sensor above my heart. "Match over," the new scoring system announced, "Drew Davis wins over Justin Mills.""I'm still better than you, for all of your intelligence," he taunted at me.He always was trying to provoke a fight with me. Next was the self-defense class that our school was making required after what happened in Colorado. I guess they wanted students to be able to repel any future shootings. I personally think that teaching everyone to fight just gives them a weapon of their own. I hurried to class, yet was still late. "Remember," the teacher was saying, "if your opponent is armed, go for the hand. Never let the gun or knife aim at you. The best thing to do is kick the hand with the weapon."The teacher then proceeded to demonstrate the exact technique Drew used to disarm me in my last fencing match. It was almost the time to go to lunch when I heard Drew's voice come over the school intercom. "All students and staff, the school is now taken over.

Macbeth :: essays research papers

Through the chronicles of history there have always been heroes. Men and women that stand up and take charge and are moral leaders of countries. Joan of Arc, Napoleon, Genghis Khan and Churchill are only a few examples of people that are remember eternally for what they have done. There are also other leaders that people would like to forget because they are moral cowards killing their subject and causing evil. Stalin, Fidel Castro, and the Character of Macbeth are all examples of this. Macbeth is a moral coward. During the play Macbeth often shows that he is morale coward. For instance, when he is planning Duncan’s murder. Likewise he also shows cowardice by killing Banquo. Lastly he shows how spineless he is when he orders Macduffs family to be murdered. A coward is an individual that is easily scared or has difficulty performing functions because of possible reprocutions. Macbeth shows notable cowardice when planning the murder of Duncan. Macbeth leans from one side to the other because he is fearful of the reprocutions. Macbeth says, “ If {we} should fail';. This shows that he is fearful and too cowardly to act. Lady Macbeth also states, “Are thou afeard to be the same in thine own act';. Again showing how cowardly Macbeth is because he will not act. Likewise Macbeth is a coward because he murders Duncan in the middle of the night and does not give a formal challenge. Instead he pretends to be his friend then kills Duncan while he is sleeping. This is what a coward would do. Likewise Macbeth also shows cowardice by killing Banquo. This shows cowardice on Macbeth’s part because his only true reason for killing him is that he is afraid of Banquo’s royalty of nature. Banquo poses no real threat to Macbeth’s throne and is visibly loyal to him. Still Macbeth fears Banquo because he is a good guy and is very respected. Macbeth is spineless because he even believes that his friend is after him and is a danger to his throne. Macbeth says “our fears in Banquo stick deep, and in his royalty of nature reigns that which would be feared';. Macbeth is pusillanimous to the point that he even believes that his friend posses the greatest opposition for him as king. As well as this Macbeth is also a coward because he himself does not kill Banquo.

Effects of Globalization on the Micro Level

Globalization was generally derived from the assumptions of neo-classical economics. In order for a country to achieve economic development, it must open its economy to trade liberalization. Trade liberalization serves as a redistribution mechanism of capital and goods. Poor and developing countries can export unlimited volume of goods and services to developed countries. Added to that, the capital inflows from developed countries would serve as a stimulant for capital build-up in the recipient country (developing countries). Because developed countries usually experience labor shortages, labor immigrants from developing countries would serve as the compensating medium. Here economists assume that the â€Å"income† derived from labor migration would then serve as capital outlay. While for many economists globalization is a positive force of development, certain practical issues were laid exposing the bad effects of globalization on the micro-level (individual and communal). There are generally two negative impacts of globalization on the micro-level. The first impact focuses on the condition of the labor force of developing countries (exposed to globalization). It is generally noted while globalization aims for wealth redistribution between developing and developed countries, inequality in terms of income and capital increased (Goldberg, R.K., and N. Pavcnik, 2006). Skilled workers from developing countries are paid less than unskilled workers from developed countries. In China, for example, after opening to globalization, several multi-national corporations (which are based in developed countries) transferred a significant portion of capital to the country. The reason can be derived from the cost of labor in the country. It is estimated that the cost of labor in China is one-eight (on the average) compared to labor cost in developed countries (Goldberg, R.K., and N. Pavcnik, 2006). Multi-national corporations found it rational to shift a significant portion of their capital to labor-rich China. The economic assumptions are clear. Labor surplus would drive the market to realign wages. The more workers, the less average labor price. The inverse relationship between the number of needed workers and labor price pushed these corporations to increase their capital inflow to China. Needless to say, because labor costs are below the market price of labor, these multi-national corporations can increase their profit level, generating new capital (to be transferred to the â€Å"mother† country). Added to that, it was found out that after 10 years of exposure to trade liberalization, China experienced vast disparities in terms of income of its own citizens. Urban workers, on the average, have generally higher incomes than rural workers. Needless to say, these urban workers are generally better off than their rural counterparts. Thus, the vast disparity of income between developed and developing countries is mirrored out in the labor price of urban and rural workers. It can be said that the macro-level effect of globalization resulted to internal income disparities. This owes much to the economic rationalizing of multi-national corporations regarding the â€Å"proper† handling of labor costs. Exposure to longer working hours and poor working conditions are also major impacts of globalization in the workplace. These impacts severely decreased the labor productivity of developing countries. Stallings (2007, pp. 6-7) noted that in Latin America, the opening of several countries to trade liberalization and privatization led to capital build-up in the short-run. Foreign direct investment and other capital inflows contributed to economic growth as well as sustainability of the industrial sector. The labor sector though suffered. The expected level of employment growth as well as improvement in labor productivity in many sectors of several Latin American countries was not met. In fact, some industries like the garment and textile industries suffered from stagnation and high-costs of operations. Several governments were forced to implement longer working hours and tax incentives to several multi-national companies. The general effect: labor productivity decreased by half. Strikes became a common sight in the streets of major Latin American cities. Companies owned by local residents were forced to close as a result of the policy. Multi-national corporations though can easily shift their capital base to countries undeterred by political and economic debacles. We come now to the second general effect of globalization on the micro-level. Globalization requires that all national currencies be on a floating status. This would allow the efficient transfer of capital from developed countries to developing countries. As such, many economists assume that this policy would generally improve the overall economic standing of developing countries in terms of capital outlay and technology acquisition. This is though not the case. Akar (2007) noted that floating currencies would essentially alter the predictability of the market. Inflation, or in many cases stagflation, are usually the main economic problems in developing countries. Because developing countries only own a small percentage of the world’s total monetary reserve, they can easily be affected by price changes in the world market (Kasapidis, R, 1999). Price changes can destroy the predictability of the markets of developing countries. Inflation can become highly unpredictable. Thus, this puts financial institutions on a very high-level of risk. This high risk can be translated to low-level investment schedule of firms. Nonetheless, the overall interest rate increases as a result of monetary downfalls. Increases in interest rate causes inflation and concomitantly, low economic output. On the individual level, as inflation progresses, the present volume of goods and service that can be bought by the value of money is less than the previous volume of goods and services bought. In a simple relationship, globalization requires that national currencies be on a floating status. For developing countries, putting its national currencies on a floating status increases the risks on financial institutions. These risks are translated to high inflation and low economic output. The end: the current purchasing power of a consumer’s income is devalued. Bibliography Akar, O. (2007). Globalization. Available from: [Accessed 24 October 2007]. Goldberg, P.K., & N. Pavcnik.
