...- Politeness formulas in Arabic:
When talking about politeness formulas in Arabic and in English and how they are different, it is crucial to take into account the distinction between propositional content of a formula and its illocutionary force potential. A good example showing the relationship between semantic content or propositional content and illocutionary force illustrates in using congratulations in English and “shukran” in Arabic which is equivalent to “thanks”. Sometimes illocutionary force is not completely predictable, but simply can be learnt by what people agree upon. For instance, there are three expressions in Arabic performing different forces according to the matter of conventions; \baraka-allahu-fik\ “God bless you” is used to perform the act of thanking, whereas \barakafik\ “blessing in yourself” has a different force, addressing the family members and the relatives of the deceased. \mabruuk\ “blesses” is another formula used for congratulations of marriage or success in examinations.
There are many other expressions used by Arabs in one of the earliest means of demonstrating politeness in a second language which are” greetings”. Greetings actually are the first task one should know when learning a new language. In Arabic greetings; for example, one would not restrict themselves to say \ahlan wa sahlan\ “hello” rather they would precede it by \marhaba\ “welcome” and they may...

...CYPOP2-5.3 Evaluate the benefits of different types of formula that are commonly available
Breast milk is a natural form of baby food which is perfect for a baby. But there are some people who for different reasons can’t breastfeed, or have chosen not to, formula milk is the next best thing.
Scientists and medical experts have spent years developing high-quality formula milks that will provide babies with the specific nutrition that they need.
There are many different types of formula feed and there are many different factors to take into account before choosing the right formula feed.
* Health
* Dietary needs
* Age
* Cost and preparation time of different formula milks.
There are three different types of formula:
* Cow’s milk-based formula
* Hydrolysed protein formula
* Soya-based formula
Most babies can have cow’s milk-based formula, however there are some who have a health or dietary reason why they can’t.
The different range of formula milks are described below.
(information obtained from the baby centre website)
Cow’s milk-based formula
Most baby formula milks are based on cow's milk, which is modified to resemble breastmilk as closely as possible. Manufacturers modify cow's milk for babies by adjusting carbohydrate,...

What should be optimal price for different classes of tickets at ‘Formula One India Racing Event’ for Retail Customers?
1. Introduction
Formula One is the highest class of single seated auto racing authorized by the Fédération Internationale de l'Automobile (FIA). The F1 season consists of a series of races, known as Grand’s Prix held on purpose-built circuits and public roads. The results of each race are combined to determine two annual World Championships, one for the drivers and one for the constructors. The sport is a massive television event and each race is watched by over 600 million people around world.
Europe is Formula One's traditional centre, where all of the teams are based, and where around half of the races take place. However, the sport's scope has expanded significantly in recent years and Formula one event are being organized in several Asian countries including China, Turkey, Singapore, South Korea. More recently, Indian Grand prix has been announced. The first Indian Grand Prix’s race will be held at the Jaypee International Race Circuit in Greater Noida on October 30, 2011. The 5.14 km...

...The Euler’s Formula
Euler’s formula and Identity: eix = cos(x) + i(sin(x))
The world of math today is one with endless possibilities. It expands into many different and interesting topics, often being incorporated into our everyday lives. Today, I will talk about one of these topics; the most mind-blowing and fascinating formula invented, called the “Euler’s formula”. This formula was created and introduced by mathematician Leonhard Euler. In essence, the formula establishes the deep relationship between trigonometric functions and the complex exponential function.
Euler’s formula: eix=cos(x)+isin(x); x being any real number
Wow -- we're relating an imaginary exponent to sine and cosine! What is even more interesting is that the formula has a special case: when π is substituted for x in the above equation, the result is an amazing identity called the Euler’s identity:
eix=cos(x)+isin(x)
eiπ=cos(π)+isin(π)
eiπ= -1+i(0)
eiπ= -1
Euler’s identity: eiπ= -1
This formula is known to be a “perfect mathematical beauty”. The physicist Richard Feynman called it "one of the most remarkable, almost astounding, formulas in all of mathematics." This is because these three basic arithmetic operations occur exactly once each: addition, multiplication, and exponentiation. The identity also links five fundamental mathematical...

...Breastfeeding vs. Formula
Deciding whether to breastfeed or provide formula milk is a major decision amongst new mothers. As simple as it may seem, the decision to breastfeed versus formula feed babies can be difficult and one of the most important decisions a mother can make. While there is nothing wrong with giving babies formula milk, breastfeeding should be the number one choice for mothers. As breast milk provides more nutrients, is naturally produced by mothers and is less expensive, breastfeeding is more beneficial than formula milk.
When examining the benefits of breastfeeding as opposed to formula milk, breast milk tops the list with the nutrients and antibodies it provides. As breast milk contains antibodies that formula milk does not, this provides extra protection for babies against diseases and viruses. The first milk a baby receives while breastfeeding is colostrum. Colostrum is rich in nutrients and the mother’s own disease-preventing antibodies which may protect the baby from certain viruses (Kutner, 2012). Thus, breastfeeding babies contribute to building babies’ immune systems. As the breast milk matures, “the cells, hormones, and antibodies [in breast milk]…protect babies from illness” (Womenshealth.gov, 2011). This combination is unique to breast milk and is not contained in formula milk. On the other hand, some...
