  • Physics is as well as basic science because the physical laws governing all other natural sciences. This means that the natural sciences as biology, chemistry, geography ... study only specific parts of nature and must comply with the laws of physics. For example, the chemistry of these substances are governed by the physical laws of quantum mechanics, thermodynamics and electromagnetism.

  • The Physical Chemistry In Brief offers a digest of all major formulas, terms and definitions needed for an understanding of the subject. They are illustrated by schematic figures, simple worked-out examples, and a short accompanying text. The concept of the book makes it different from common university or physical chemistry textbooks. In terms of contents, the Physical Chemistry In Brief embraces the fundamental course in physical chemistry as taught at the Institute of Chemical Technology, Prague, i.e.

  • Metal foams are a new, as yet imperfectly characterized, class of materials with low densities and novel physical, mechanical, thermal, electrical and acoustic properties. They offer potential for lightweight structures, for energy absorption, and for thermal management; and some of them, at least, are cheap. The current understanding of their production, properties and uses in assembled in this Design Guide.

  • In Section 1.5 of the textbook, Zak introduces the Lagrangian L = K − U , which is the difference between the kinetic and potential energy of the system. He then proceeds to obtain the Lagrange equations of motion in Cartesian coordinates for a point mass subject to conservative forces, namely, d dt ∂L ∂ xi ˙ − ∂L = 0 i = 1, 2, 3. ∂xi (1)

  • The technique now known as MS has its roots in atomic physics at the beginning of the twentieth century, when it was originally applied by physicists toward answering questions on the nature of atoms. Throughout much of the 1800s, the prevailing wisdom held that atoms were indivisible, that all atoms of a given element had the same mass, and that the masses of all elements were multiples of the mass of hydrogen [7–9].

  • We present the appearance of some new interaction in the MSSM with CP violation. We give analytic formulae and perform an evaluation of the effects of these new interactions on some processes concerning the productions and decays of squarks. We find that these effects are typically of $-3.5 \% $ to $+3 \% $ depending on each process.

  • We present explicit formulas representations of the real diamond Lie algebra obtained from the normal polarization on K-orbits. From this we have list irreducible unitary representations of the real diamond Lie group that is coincide with the representations via Fedosov deformation quantisation. Here the computations are more simple for use star-product.

  • In this article, we report on the preparation of CdSe quantum dots (QDs) by sol-gel method and their optical properties. The average size of QDs is also estimated by using various ways, such as the Scherer’s formula, The Effros-Brus-Kayanuma’s theoretical expression, TEM etc. The TEM images of samples show that the mean sizes of QDs are 4 nm. The mean sizes of QDs are smaller than that of other methods and arranging from 2 to 3.6 nm.

  • This paper considers the exponential stability and stability radius of time-invarying dynamic equations with respect to linear dynamic perturbations on time scales. A formula for the stability radius is given. Keywords and phrases: time scales, exponential function, linear dynamic equation, exponentially stable, stability radius

  • This paper deals with a formula of stability radii for an linear difference equation (LDEs for short) with the coefficients varying in time under structured parameter perturbations. It is shown that the lp− real and complex stability radii of these systems coincide and they are given by a formula of input-output operator. The result is considered as an discrete version of a previous result for time-varying ordinary differential equations [1]. Keywords: Robust stability, Linear difference equation, Input-output operator, Stability radius ...

  • The inspiration for Building Systems for Interior Designers came when I tried to teach interior design students about all the ways buildings support our activities and physical needs—without an adequate textbook. I needed an approach that supported the special concerns of the interior designer, while connecting those issues to the work of the rest of the building design team.

  • Simple Physics Simple Physics In the quest for more expressive animation, you will find that adding physics to animations, games, and similar projects can really elevate them to another level of user enjoyment. The visual appearance and, in interactive scenarios, even the user experience of a project are sometimes dramatically enhanced by surprisingly small code additions. We’re going to be discussing some basic physics principles in this section, but it’s more important for you to understand their effects than to focus minutely on the math and science behind them.

  • This book evolved from the first term of a two-term course on the physics of charged particle acceleration that I taught at the University of New Mexico and at Los Alamos National Laboratory. The first term covered conventional accelerators in the single particle limit. The second term covered collective effects in charged particle beams, including high current transport and instabilities. The material was selected to make the course accessible to graduate students in physics and electrical engineering with no previous background in accelerator theory.
