Principles of X-ray Diffraction Diffraction effects are observed when electromagnetic radiation impinges on periodic structures with geometrical variations on the length scale of the wavelength of the radiation. The interatomic distances in crystals and molecules amount to 0.15–0.4 nm which correspond in the electromagnetic spectrum with the wavelength of x-rays having photon energies between 3 and 8 keV. Accordingly‚ phenomena like constructive and destructive interference should become observable

Peer Practice/Reciprocal Learning Lesson The Reciprocal Learning Strategy is a “unique partnership that is forged between pairs of students working together to practice previously presented skills and information‚ to increase reading comprehension of information-rich texts‚ and to develop the thinking processes needed to become competent problem solvers” (Silver‚ Hanson‚ Strong‚ & Schwartz‚ 2003‚ p.200). "The purpose of reciprocal teaching is to facilitate a group effort between teacher and students

Jazz and World War II: Reciprocal Effects and Relationships Both Jazz music and World War II had a significant impact on each other. Jazz music boosted the morale of soldiers fighting abroad and also lifted the spirits of their loved ones back at home. Many jazz musicians were soldiers‚ and several others traveled overseas or across the country to entertain U.S. troops. Among these performers were Bing Crosby‚ Artie Shaw‚ and Benny Carter. Jazz music was not only evident in American culture‚ but

used to cut metals and woods. The term reciprocal refers to the up and down motion of the cutting blade. It is the Best Reciprocating Saw a peculiar motion helps to maintain accurate cutting line and finishing. Reciprocal Saws consume less energy compared to other saws. They are economical and durable. Many companies manufacture reciprocal saws.

Nice guys finish first‚ a chapter title in R. Dawkins ’ revolutionary popular science book the Selfish Gene. Although true altruism can not exist according to the classical theory of natural selection if such an evolutionary protagonist as RD has time for it‚ then there must be a good reason. In fact‚ we see much behaviour in nature that appears altruistic: alarm calling‚ guarding‚ defence and foraging by non-reproductives and grooming are just a few examples. Since work first began on altruistic

LINEWEAVER-BURK PLOT A graph of the double reciprocal equation is also called a Lineweaver-Burk‚ 1/Vo vs 1/[S]. The y intercept is 1/VMAX; the x-intercept is 1/ KM; and the slope is KM/VMAX. Lineweaver Burk graphs are particularly useful for analyzing how enzyme kinematics change in the presence of inhibitors‚ competitive‚ noncompetitive‚ or a mixture of the two. There are three reversible inhibitors: competitive
