This radiation from the device interacts with food or water molecules as the positive and negative ends of these waves interact with the positive and negative ends of water and food molecules. The high-watt alternating current in microwave ovens interact with and bombard food molecules, which then rotate at rates of millions of times per second. This agitation of food and water molecules results in friction. The friction heats the food and damages its molecules, a process referred to as structural isomerism.

As the study stresses microwave oven is used for heating and cooking. A microwave oven has control and high-voltage sections.  The former section regulates the system’s power output. This section is composed of an electronic timer in addition to other protection and interlocking devices. As its name suggests, the high-voltage section is used to step up the output of the system to high voltage. This high voltage is changed into microwave energy. The working of the microwave oven starts when electricity from the socket outlets moves to the gadget’s power cables, fuses, protection circuits, which turns off the gadget in case of overheating. Under normal heating, the electric power goes through the timer and interlock circuits. With the oven door closed, electric path is established via the interlock switches. ...Download file to see next pagesRead More

Security System In Reference To Immigration

 When James Hollifield delivered this paper at the 1989 Annual Meeting of the American Political Science Association barely three months before the descend of the Berlin Wall he seemed to foretell the crisis situation which the member states of the European Union (at that time the European Community) and the United States would visage when coming to terms with the unprecedented international migration flows they experienced in the early 1990s. With the collapse of communism in Europe and the subsequent rise of irredentist and nationalist tendencies on a global scale, both Western Europe and the United States were faced with the challenge of sustained wide-scale migration flows into their territory throughout the early half of...

Has Government by States Given Way to Inter and Non-State Governance

The application of theories related to the state and its governance can be proved very helpful towards the creation of an effective and well-structured state. However, the phenomenon of a ‘subjective’ interpretation of the above theories is common especially when there are specific targets that need to be achieved by the interested parties (usual participants in a state’s political or social life). For this reason, it is necessary that specific rules and guidelines are followed when studying and interpreting the views of theorists regarding the position, the role and the power of the state.

Within the state, there are many ‘political’ and ‘social’ forces that try to impose their...

The Impact of Globalization on National HRM Systems

Two countries that demonstrate HRM practices that are at polar ends of the spectrum are Japan and the United States; however while globalization has produced some diffusion in practices, national systems remain substantially unchanged.

The phenomenon of globalization is inter-connectedness among the various nations of the world on the basis of economic ties. According to Thomas Friedman, globalization is the “inexorable integration of markets, nation-states, and technologies…..the spread of free-market capitalism to virtually every country in the world.” (Friedman, 2000, p 7-8). Mittelman also refers to globalization as a historical transformation - “a political response to the expansion of mark...

Methodological Approach in a Quantitative Research

...). The result of a qualitative research is depended on the analytical skills of the researcher. The researcher should possess a good observation skill in order to make proper analysis of the situation. As the name describes quantitative research deals with numbers or items that can be expressed in numbers. It gives information about the number of people involved in the topic of the research. “Quantitative research is all about quantifying the relationships between variables. Variables are the things you measure on your subjects, which can be humans, animals, or cells.” (Hopkins 1998). A quantitative research is usually made by making analysis of the data collected from the public through questionnaire or interview. Survey is always...

Provisions for Gas, Electricity, and Water Markets

The traditional regulation relied on the static concept of competition in which the perfectly competitive markets are in equilibrium and, when that equilibrium is disturbed, move to equilibrium. This traditional approach has been eschewed in most of the British privatised utilities. However, it has a crucial problem. It requires the would-be regulator to identify the outcome of a perfectly competitive market which is impossible therefore the approach has no firm anchor and leads on to arbitrary regulation (on opinions).

At the time of privatisation, the traditional approach was already in some disrepute and the founding fathers of British regulation were searching for another anchor and, in particular, a means of regul...

Investment Appraisal and Management Control

It is important that managers are aware of the consequences of every decision they take, be it, buying a computer for a small company or a vehicle for delivery of goods, or manufacturing plant for the company or a company by itself (Duncan Williamson, 2003)

While investing on any project, the company normally would have a choice. The management needs to have a good understanding of each of these proposals and should be able to weigh the benefits and drawbacks of each proposal. All the decisions require a detailed analysis to assess whether or not the investment is feasible for the company. The feasibility of the project depends not only on the financials of the company but also partly on non- financial factors (Bized...

Building Engineering Services and Analysis of Core Systems

Finally, we will conduct an in-depth analysis of the heating and insulation systems available in modern homes and propose a strategy to optimize the energy consumption and maximize customer comfort.

Building Service Engineers are usually mechanical or electrical engineers, who do not necessarily have a degree in Building Services Engineering. They start contributing to inputs before the building construction commences. Their assessment starts with researching the suitability of the building site for construction and also foreseeing the provisions to connect services to supply lines. Based on this analysis, they conduct discussions with the client, architects and structural engineers to concur on an installation design t...

Oil Prices by OPEC and Market Fundamentals

Market failure is defined as the inefficient allocation of resources by the market, the free market is considered to optimally prices and resources in the production of goods and services, and this is because the price and quantity produced are determined by market forces which include the demand and the supply. The control of prices by a firm or an organization in the market results in market failure, therefore OPEC leads to market failure due to its nature in the market.

OPEC was formed in 1960 by 5 oil-producing countries which include Venezuela, Saudi Arabia, Kuwait, Iran and Iraq, The aim of this organization was to unify petroleum-producing countries in order to realize fair and stable prices of oil .other oil-pro...

A Hydrograph of River Cynon and Design of an Open Channel

... hours at 03:00:00, no precipitation was recorded. During the same period, the hourly observation of the river stage generated an average height of 0.263 m or a theoretical discharge of 0.263 m(Bv). This theoretical discharge may also be expressed as 15.75 m3 per second. Figure 2: Elements of the River Cynon Hydrograph The average river discharge before the precipitation started is the baseflow of the River for this analysis. After about 8 hours of precipitation, with an average height of 0.5 mm of rainfall per hour, peak rainfall of 1.2 mm was recorded at 11:00:00 of October 13. After 10 hours, and an average precipitation of 0.56 mm per hour, a second rainfall peak, also at 1.2 m was recorded on 21:00:00 of October 13. From the first peak...

Critical Review of General Electric

... intense pressure from shareholders and stock analysts to produce the returns expected of it, a 4,000% increase in stock value over the 20-year reign of Jack Welch. General Electric today has clearly lost its footing, its firm grip on markets gradually eroded. It has ceased to be the financial juggernaut derived from its engineering expertise by venturing into so many un-related business areas that it has lost its core competencies in the process. Its much vaunted invincible market share has been torn to shreds by its lesser rivals. To better understand what is wrong with General Electric, it is best to re-examine its whole corporate strategy and structure in light of a changed economic environment. There is a debate going whether G.E...
