  • 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.

  • Any value that you'll run across as an engineer will either be unitless or, more commonly, will have specific types of units attached to it. In order to solve a problem effectively, all the types of units should be consistent with each other, or should be in the same system. A system of units defines each of the basic unit types with respect to some measurement that can be easily duplicated, so that for example 5 ft. is the same length in Australia as it is in the United States. There are five commonly-used base unit types or dimensions that one might encounter (shown with their...

  • Construction activities have significant potential to have adverse environmental impacts. During this phase, often a large transient workforce is employed, workforce numbers tend to peak and material and equipment movements tend to be large. Impacts are typically related to land disturbance caused by earth- works, air emissions from dust, noise from equipment and construction activities and heavy volumes of traf- fic on access roads. In many cases, specialized third party companies and consultants conduct mine construction activities.

  • Soils are aggregates of mineral particles, and together with air and/or water in the void spaces, they form three-phase systems. A large portion of the earth’s surface is covered by soils, and they are widely used as construction and foundation materials. Soil mechanics is the branch of engineering that deals with the engineering properties of soils and their behavior under stress.

  • Materials are evolving today faster than at any time in history. Industrial nations regard the development of new and improved materials as an “underpinning technology” – one which can stimulate innovation in all branches of engineering, making possible new designs for structures, appliances, engines, electrical and electronic devices, processing and energy conservation equipment, and much more.

  • The aim of the study was to investigate the crystallization kinetics and solidification behaviour of Fe60Co8Mo5Zr10W2B15 bulk glass forming alloy. The solidification behaviour in near-equilibrium and non-equilibrium cooling conditions was studied. The eutectic and peritectic reactions were found to exist in the solidification sequence of the alloy. The bulk metallic glass formation was achieved by using two methods: quenching from the liquid state and quenching from the semi-state.

  • The issue of the equilibrium level of credit in the economy is addressed in the liter- ature from di®erent perspectives. Several papers use theoretical models to analyze the equilibrium level of credit over business cycles by identifying phases of credit rationing or credit booms (Kiyotaki and Moore, 1997; Azariadis and Smith, 1998; Lorenzoni, 2008). In the similar spirit, DSGE models have been used recently to analyze the asymmetry in the behavior of borrowers and lenders in reaction to structural, and in particular ¯nancial shocks (Iacoviello, 2005; Gerali et al., 2010)....

  • The equilibrium of the pollutant between the groundwater and the solid phase of the soil is described by a Freundlich isotherm. This nonlinear sorption isotherm does not vary in time. Sorption takes place at the so-called "sorption sites" of the soil. Two classes of sorption sites are distinguished (Boesten, 1986; Brasseau, 1992b). The sorption sites of class 1 are continuously in equilibrium. The class 2 sorption sites are not continuously in equilibrium with the soil solution.

  • As life broadens with advancing culture, and people are able to appropriate to themselves more of the various forms of art, the artist himself attains to greater power, his abilities increase in direct ratio with the progress in culture made by the people and their ability to comprehend him. When one side or phase of an art comes to be received, new and more difficult problems are invariably presented, the elucidation of which can only be effected by a higher development of the faculties. There is never an approach to equilibrium between the artist and his public.

  • For bovine serum amine oxidase, two different mechanisms of substrate-induced inactivation have been proposed. One consists of a slow oxidation by H2O2of a conserved residue in the reduced enzyme after the fast turnover phase [Pietr-angeli, P., Nocera, S., Fattibene, P., Wang, X.T., Mondovı`, B. &Morpurgo, L. (2000)Biochem. Biophys. Res. Commun. 267, 174–178] and the other of the oxidation byH2O2of the dihydrobenzoxazole in equilibrium with the product Schiff base, during the catalytic cycle [Lee, Y., Shepard, E., Smith, J., Dooley, D.M. & Sayre, L.M. (2001)Biochemistry40, 822–829]. ...

  • 5A, 4A and 3A zeolites were successfully prepared using solid seeds at pilot scale. The adsorption properties of 5A, 4A and 3A zeolites were determined by adsorption isotherm method. The results showed that water adsorption capacity and rate of 5A and 4A zeolites were higher than those of 3A zeolite. Even at low vapor pressure of water of 4 mmHg, adsorption capacity of 5A, 4A and 3A zeolites also reached about 23%, 22% and 17%, respectively, and was much higher than that of silicagel (5%).
