Your essay should: -explains how different type of waves are used to diagnose / cure different diseases. -discusses the effectiveness of science and its application in solving the problem or issue. -discusses and evaluates the implications of the use and application of science interacting with at least two of the following factors: moral, ethical, social, economic, political, cultural and environmental. You should also: -use sufficient scientific language correctly. -communicate scientific information effectively. -fully documents sources of information correctly, appropriate to the task The application of waves in medicine: Shock wave: Shock wave is one of the wave which is used in medicines. This wave was introduced 20 years ago. This application changed the treatment of Urologists. The formation of stony concretions in the bladder or urinary tract. Shock waves can treat kidney and urethral stones. Shock waves have also been used to treat fractures. The concept of orthopedic is that the shock wave reactivates healing, surrounding tissue and bones, by micro disruption which means disorder of vascular tissues to grow on local bases. It basically helps in healing and recovering tissues. Radio wave: We have learned about the understanding of radio waves by the experiments of Hertz. Radio waves are used to transfer the pattern of a patients heartbeat by a monitor to a patients home or to a nearby hospital. They are also used to convey the condition of a patient from an ambulance to a hospital so that they are ready for the tangents emergency. Radio waves are used in medicine when paramedics who is a person trained to do medical work are connected to the scene where they are to do for the upcoming patient. Electromagnetic wave: Electromagnetic waves are produced by the motion of electrically charged particles. These waves are also called electromagnetic radiation because they radiate from the electrically charged particles. They travel through empty space as well as through air and other substances. Electromagnetic waves at low frequencies are referred to as electromagnetic fields and those at very high frequencies are called electromagnetic radiations. Electromagnetic wave plays a big major role in daily life. Electromagnetic waves are used in communications, radio and television broadcasting, cellular networks and indoor wireless systems. From the results of innovations, the use of this field is very high as people prefer more of new technologies now a day. The increasing number of mobile phones users rise significant concerns due to its potential damage on people exposed by radionuclide waves. Since mobile phones are used in positions very close to the human body and require a large number of base station antennas, the public and the scientists have doubts on its damages on human body. Ultra sound: In sound waves, waves are send into bodies and are reflected back at the interface between tissues. The time taken by the waves to reflect and return tells the depth of the reflected area. The research for sound wave went across human life and had affected since the world war 2 when the research was being done during the war of sound negotiation and ranging. In sasss for gray scale images, in 1965 for real time imaging. And today used in medical imaging. Sound waves have two types of waves, specula which means reflection from large surface and scattered which means reflection from small surface. Ultra sound waves are used as medicines as it captures the internal organs and structures . Ultra sonic waves: The application of ultrasonic wave in medicine is that it used n x-rays and magnetic imaging. Among the various modern techniques for the imaging of internal organs, ultrasonic machines like x ray are very expensive including its treatment. Ultrasound is also used for treating Joint pains and for treating certain types of tumors for which the mentioned problems are heated. A very effective use of ultrasound deriving from its nature as a mechanical vibration is the elimination of kidney and bladder. One of the important advantages of ultrasound is that it is a mechanical vibration. It can also be used in places where x-ray is damaging. Ultrasound, on the other hand, gives good contrast between various types of soft tissue. All the included waves have advantages and are helpful in humans daily life. Some waves are also lawful in places where other medical machines are dangerous like ultrasonic waves instead of x-rays. Application of these waves also helps in economic development as more and more patients will do their surgery through these waves in medicine. Bibliography: Medical Physics Ultrasound. (n. D. ).

The Loyalty Card as Promotion Tool Essay Example | Topics and Well Written Essays - 6250 words - 1

The Loyalty Card as Promotion Tool - Essay Example Humby and Hunt (2004) are of the opinion that loyalty is more of an emotional concept thus resisting the definition in terms of behavior. This, therefore, champions that loyalty is an emotional concept resulting from the trust. Others also define loyalty as emotional concept built on empathy (East 1997). Building on the idea and recognition that opinions and feelings are active, variables that include but not restricted to social, physical environments, as well as individual abilities, have been known to pre-empt action. On the contrary, this view can be seen as being loyal functionally in that customer tends to be loyal to a company only because of convenience (Barnes 2002). According to (Grisaffe 2001), loyalty does not rotate around behavior, for instance, other is the buyer who has developed the cognitive rule in that they only buy low priced products, because of this such customers will look loyal to that brand over a period of time. This will only be interrupted by the entrance of another brand which is priced lower than the previous. The customer will again change to become loyal to the new product in the market. From this, it is evident that customers are more loyal to their decision rules as opposed to the brands and thereby a proof that loyalty is more than behavior. Of several definitions, the characterization seemed most suitable when discussing the Tesco Clubcard. Suggestions that daily life of loyalty entails â€Å"emotional commitment† and â€Å"monogamy† where one choice overrides the rest has been brought forward (Humby and Hunt 2004, pg 9). To bring out the comparison, retail loyalty concentrates on achieving a bit of goodwill, a slight margin of liking, a rise in the shift in terms of buying tendency. Customer satisfaction can be described in simple terms as the measure of a customer’s expectation is met in totality or not.

The average gross margin for a single coffee shop in the country is

Substitution and Income Effect

Substitution and Income Effect Tendekai Mudariki The price of any given product will always change the customer’s choice of purchasing this can be in terms of quantity, quality or choosing the opportunity cost. In my essay I will be looking at how an increase in prices affect the substitution effect and the income effect and how customers react if the good has many close substitutions when there is an increase in price. Under the Substitution effect it suggest that the rise of the price in a good or decrease in income will leave the customers having to choose the alternative goods for example when the price of Coca-Cola drink raises this will lead to the rise of demand in Pepsi because Pepsi is the next best thing to a Coca-Cola. The substitution effect can also be used in reference in how workers can have a pick between leisure and wages, the more money on wages the less leisure time since wages will be more profitable than leisure. This effect tends to limit the customers buying demand behaviour that is limiting the choice of the consumer since they will not be able to purchase their choice of good.as shown below (in figure 1.1) The impact that a change in the price of a good has on the quantity demanded of a certain good, this will always lead to change in relative prices the rise of the price will make the quantity demanded to be less forcing some of the customers away to the next best thing tha t they can have. The income effect is the response of the quantity that is demanded to a change of real income or the price that is the rise of price in goods, (refer to figure 1.1) in the graph below shows the demand curve as it links up the relationship between the price of a certain item and the quantity that is demanded that is over a certain time. When the price falls there are two reasons why there will be more demand and this includes the substitution effect and income effect .the impact that a change in the price of a good has that effect on the quantity demanded of the good which then leads to the change of price of the good (substitution).the impact of a change in the quantity demanded of the good due to the change of their real income not being able to meet the quantity of goods that will satisfy them but still buy the good anyway but only have to make it lesser. The demand curve enlightens up the relationship between the price of the goods and the quantity demanded that is after a period of time. Considering both sides the substitution effect as shown on the diagram above from both sides of a price change that is going up and down. If we consider the both sides the higher the price an increase in price causes a decrease in the relative prices of substitute goods. Buyers tend to buy more of the other substitute goods and less of the good. The result is a decrease in thequantity demanded, and the lower the price then it leads to a decrease in price causing an increase in the relative prices of substitute goods. Buyers are inclined to buy less of the other substitute goods and more of this good. The result is an increase in the quantity demanded. As price falls, a person’s opportunity cost of purchasing the product falls as shown in the diagram above. A good with many close substitutes is likely to have an elastic demand .This is due to the price rise, buyers can actually choose to buy one of the close substitutes if there is a price increase of a good by shifting to one of the cheaper substitutes. However fewer substitutes’ choices will limit the options to shift. It is Important to distinguish between the income effect and the substitution effect of a price increase and the separation of the two is shown in figure 2 and it’s called the indifference theory. The price change can affect the way the buyers decisions in terms of buying staff this is called the income effect. Increases in price, while they dont affect the amount of your available budget, make you feel poorer than you were before, and by so you buy less of the product. Decrease in the price make you feel more superior and confident in terms of buying, and can the lead you of buying more of that good. When price increases, the demand for x changes because (1) good x is now more expensive relative to good y, and (2) the consumer’s purchasing power has gone down. Substitution Effect—the change in demand resulting from a change in the price ratio, leaving utility unchanged. Income Effect this is the change in demand resulting from the change in purchasing power (movement from the initial indifference curve to the final indifference curve), leaving the price ratio unchanged. The total effect = substitution effect + income effect. The substitution effect is always negative, due to diminishing MRS. The income effect is negative for normal goods(the substitution effect), and positive for inferior goods. A giffen good is an inferior good with the unique characteristic that an increase in price actually increases the quantity of the good that is demanded. This provides the unusual result of an upward sloping demand curve. This happens because of the interactions of the income and substitution effects. Depending on whether the good is inferior or normal, the income effect can be positive or negative as the price of a good increases. An inferior good means an increase in income causes a fall in demand.an inferior good has a negative PED. An example, of an inferior good is Tesco value bread. When your income rises you buy less Tesco value bread and more high quality, organic bread. Normal Good This means an increase in income causes an increase in demand. It has a positive PED. Note a normal good can be income elastic or income inelastic. The graph below shows the income effect and the substitution effect of a price increase for a normal good and inferior goods after a rise in price of a certain good. The Income Effect is the effect due to the change in real income. When the price goes up that means the consumer is not able to buy as many bundles that she could purchase before. In real terms this means that the customer now feels poorer. On the diagram 1.3 it shows the quantity of goods consumed for a normal good and it shows the figures A=14, B=4 and C=7 .from C to A it shows the substitution effect after subtrac ting 14 from 7 and from C to B after subtracting 7 from 4 it shows the income effect and the total effect is the total between the substitution and income effect as shown in the diagram (-7-3=-10). The same workings also applies to the inferior goods too. As shown in the diagrams when the price of the good goes up the quantity goes down Summing up my essay if a good is inferior, a drop in income (represented by a price increase) increases the quantity of the good that is demanded. The substitution effect is negative for any good that experiences a price increase. A giffen good faces an upward sloping demand curve because the income effect dominates the substitution effect, meaning that quantity demanded increases as price rises.

Gun Control Laws Take Guns Away from Law-abiding Citizens Essay

Gun control is a very big issue in the United States today. Many people don't agree with the gun control laws that they have today. Gun control laws only take guns away from law-abiding citizens. Many people have their own reasons for owning a gun. Why would the government want to make it harder for people to own a gun? People that own guns are not very likely to be attacked by criminals. Owning a handgun is one of the best ways of protection. The second amendment states "the right to bear arms" does this grant everyone a right to own a gun? Gun control laws have not been proven to do anything for citizens. Gun control laws just make it harder for a good guy to own a gun. Gun control laws are not a good idea. Gun control only takes guns away from law- abiding citizens and it does nothing to stop criminals from buying illegal guns, who are unlikely to obey the law and register their guns (Long 45). In many cases the term gun control is improperly used. The definition of gun control is; government regulation of possession and use of firearms by private citizens (Zimring 23). The government is using it as way to take our right to bear arms. There are many reasons that people want to own a gun. One of the main reasons that people own a gun is protection. In a survey given about guns, " self defense" was the primary reason for owning a gun (Nisbet 114). Guns provide a great source of psychological reassurance even among citizens who are not especially concerned about the fear of crime of being victimized (Long 53). The right of self-defense and the right to use firearms for defense of self and family are the cornerstone of individual rights enumerated in the U.S. constitution (Nisbet 89). Why does the government ... ...r when they own a gun. The second amendment clearly states "the right to bear arms" doesn't let the government try to change that. Don't let gun control laws fool the public, because they have not been proven to reduce crime at all. So go out and buy a gun before that right is taken away. Eventually guns might just be a thing of the past. So practice your right to protect your country and vote against gun control any time that you can. Work Cited Page Long, Robert. Gun Control.

Bucket List Destination

Our trip to Italy We were planning a trip, but we were not sure where to go. Our options were to go to Europe or South America. After checking prices and the offers we decided it was better to go to Europe. But we concentrated the trip only to Italy, because it seemed to be the best option for its history and food. We left from PR on a Saturday morning, next stop was NY City. At the airport we got chill at some bar and get ready for a lot of hours in a flight.At the airplane, as usual, we where boring, watching a lot of movies, eating bad food, and desperate to get at our destination. Finally, at Venice! Once we got there we take a bus that leave us close to the hotel, but like good pertinacious, we don't read or look at the map to see where was the exact location of the hotel. We walked for almost 2 hours to see where was the hotel. After walking under the rain and freezing we decided to ask where was our hotel. It was close to the bus station, only 5 minutes walking!!!We do the che ck in and took a little nap. I was so tire because of the flight. Every day we wake up at 8:00 a. M. To enjoyed the breakfast and after that walked all day to see the different museums and places in Venice. After a few day eating pasta and drinking wine I was looking forward to our next place, Florence! At Florence we walked like the airwoman race, a lot of miles to get to our destiny. It was the first time I used a train, a really fast train! It was awesome! We enjoyed the view of the place, the wineries, the houses, everything was pretty.When we where at Florence it was Easter celebration, we saw all the Catholic rituals and it was amazing to see all the people getting together to celebrated that holiday, a lot of people celebrating the same. As usual, we walked a lot every day. In the last day at Florence we got a reservation at Ditto's Restaurant to taste a Bisect Florentine, it was a piece of meat almost raw, so bloody and red, I can't eat it, but the owner was very nice. The n ext day went to Rome, my favorite destination in the entire trip.We saw the culture, the famous places, the Coliseum, it was really awesome. When I finally saw the Coliseum I can't describe what I felt. A lot of history in front of my eyes, I can't compared that experience to anything before. During the entire trip I was really happy, I can't believe I went to Italy, one in the bucket list destination, I was happy as a child that goes to Disney Land for the first time. It was one of my best trips ever and I'm looking forward to go again to Europe. Bucket List Destination By shillelaghs

This paper will reflect on the definition of personality...

This paper will reflect on the definition of personality and some key definitions that define our behavior but not us as individuals. Understanding personality differences is a start of knowing how to adapt when other personalities are presented. In order to understand what personality is let start by defining personality. Personality is a combination of his or her interests, attitude behavior patterns and other traits that may continue throughout his or her life span. â€Å"The definition has two important components. First, each person’s of thinking, feeling, and behaving makes him or her distinctive. The second defining component is the notion that an individual’s personality is relatively consistent (Davis, Palladino, †¦show more content†¦For example our daughter usually dates someone exactly like her father and our son will date someone like their mother. The third personality theory is Cognitive- Behavioral Perspective focuses on patterns of thinking and behavior and how these patterns are reinforced and maintained by the person within his or her environment. It is a practical approach in which the main object is to define goals and techniques to reach the client. Last but not least the Humani stic Perspective that emphasizes on individuals control of their behavior. It focuses on conscious influences on behavior and on the aspects of human nature (p. 475). It looks at the person as a whole including the mind, body and soul. Perhaps the theories are unfamiliar but the nine different defense mechanisms possibility can help understand them. The nine defense mechanisms are; anxiety, denial, repression, projection, reaction formation, displacement, sublimation, compensation and regression. A person can have just one defense mechanisms are several and identifying them early can help the individual person and his or her surroundings. Denial has to be the most common defense mechanisms because most people don’t want to know the truth especially when it comes to their children.
