The 1960s was an era that changed America in so many ways. While many of the changes were in Civil Rights and in humanity in general‚ another change would come in the form of science and even the way we look at body armor and self protection in general. 1967 was the year in which a the world would have been introduced to Kevlar. Kevlar Not only influenced our military it also has changed the face of everyday American products. Discovered in 1965 an American chemist with the name of Stephanie Kwolek

spectroscopy which is defined as a combination of imaging and spectroscopy[2]. The modality of the imaging system will be a hyper cube with 2D spatial information and spectral information[14]. The materials in the scene are identified using spectral information. The location in the scene is identified using spatial information. In addition to image information‚ the classification and identification information is provided in Hyperspectral imaging systems[4]. It is useful for various industrial and

X rays from a copper X-ray tube (λ = 154) were diffracted at an angle of 14.22 degrees by a crystal of silicon. Assuming firstorder diffraction (n= 1 in the Bragg equation)‚ What is the interlunar spacing of silicon? nλ = 2d sin θ 1(154) = 2d sin 14.22 154 = 2d (0.245) 2d = 626.92 d = 313.46 2.

candy such as rock candy‚ fudge and glass candy. Despite only using boiled water and sugar‚ the type of candy formed is dependent on the presence of sugar crystal formation and its size. At a molecular level‚ sucrose molecules form a small crystal that is orderly arranged in three dimensions.These molecules are attracted and held together by intermolecular forces. However‚ when water is added to the granulated sugar‚ the sucrose molecules begin to dissociate from one another due to the attraction of

chewy (fudge)‚ gritty (cotton candy)‚ or hard (glass candy). You can make fudge by continuously stirring the sugar syrup after a period of cooling‚ so when the sugar crystals form‚ they stay very small and do not grow that to be big. You can make cotton candy or glass by cooling the syrup quickly to keep the crystals from forming. The main difference between the types are whether sugar crystals are allowed to form and if they do what their size is. The text is structured as an article and Tom Husband

Lab Report 3: Electrical Properties of Ceramic Materials Lab III: Physical Properties of Materials By Will Paxton 3/5/07 Abstract The electrical properties of 5 different samples were studied. Characterization of these samples was through the dielectric properties‚ as this is a very important step. The capacitance was measured for each sample incrementally while heating them up to 135ºC. In a second part to the experiment‚ piezoelectric samples were studied‚ and their piezoelectric coefficient
