In addition to the 'pure vowels' (ones where the tongue positioning is fairly static) shown above there is also the set of vowel diphthongs. These are effectively long vowels during which the tongue moves to produce a definite change of quality during the sound. In phonetic transcription we usually use a pair of linked symbols for each diphthong - one indicating the quality of the sound at the start of the vowel, and the other indicating its quality as it ends. Examples of diphthongs are found in words like 'boy', 'hear', 'may', 'my

For a given mass flow m ind thrust F, we would like to minimize the running power

The Poisson approximation to the binomial distribution The binomial distribution, like the Poisson, is that of a random variable taking only positive integral values. Since it involves factorials, the binomial distribution is not very convenient for numerical application

The question of growth is nothing new but new disguise for an age-old issue, one which has always intrigued and preoccupied economics: the present versus the future. -James Tobin If you have ever spoken with your grandparents about what their lives were like when they were young, most likely you learned an important lesson over about economics: material standards of have improved substantially over form time for most families in most countries

henols are compounds that have a hydroxyl group bonded directly to benzene or benzenoid ring. The parent compound of this group, C6H,OH, called simply phe- nol, is an important industrial chemical. Many of the properties of phenols are anal- ogous to those of alcohols, but this similarity is something of an oversimplification.Like arylamine

In this lecture we will look at some other common systems of coordinates. We will present polar coordinates in two dimensions and cylindrical and spherical coordinates in three dimensions. We shall see that these systems are particularly useful for certain classes of problems Like in the case of intrinsic coordinates presented in the previous lecture, the reference frame changes from point to point. However, for the coordinate systems to be presented below, the reference frame depends only on the position of the particle. This is in contrast with the intrinsic coordinates, where the reference frame is a function of the position, as well as the path

1. Lipids encompass a large and diverse group of organic compounds 1.1 Lipids are broadly defined as biological molecules that are soluble in organic solvents. 1.1.1 Lipids are usually extracted from biological materials by nonpolar solvents like ether, chloroform(氯仿), benzene(苯). 1.2 The biological functions of lipids are diverse. 1.2.1 Certain lipids(e.g., triacylglycerols(三脂酰甘油), commonly called fats) serve as efficient reserves for the storage of energy

1 Goodness of Fit Statistics We would like some measure of how well our regression model actually fits the data.* We have goodness of fit statistics to test this: i.e. how well the sample regression function (srf) fits the data. The most common goodness of fit statistic is known as R2. One
