  • At the beginning of the 19th century the description of matter attained, what one would call today, a scientific basis. Dalton1 supported the atomic theory with experiments permitting the development of modern chemistry. The book “A New System of Chemical Philosophy,” describes this new approach. In Fig. 1.1, an excerpt is displayed. Chapters I and II give a summary of the contemporary understanding of nature by analyzing heat and mass, the two basic building-blocks of any material. Chapter I displays the theory of the caloric as it was generally...

  • Process control is an application area of chemical engineering - an identifiable specialty for the ChE. It combines chemical process knowledge (how physics, chemistry, and biology work in operating equipment) and an understanding of dynamic systems, a topic important to many fields of engineering. Thus study of process control allows chemical engineers to span their own field, as well as form a useful acquaintance with allied fields. Practitioners of process control find their skills useful in design, operation, and troubleshooting - major categories of chemical engineering practice....

  • Gas supplies and suction To check the correct function of the oxygen failure alarm involves disconnecting the oxygen pipeline on some machines, whilst on machines with a gas supply master switch, the alarm may be operated by turning the master switch off. As repeated disconnection of gas hoses may lead to premature failure of the Schrader socket and probe, these guidelines recommend that the regular pre-session check of equipment includes a ‘tug test’ to confirmcorrect insertion of each pipeline into the appropriate socket....

  • The reactions of the flavin semiquinone generated by laser-induced stepwise two-photon excitation of reduced flavin have been studied previously (El Hanine-Lmoumene C & Lindqvist L. (1997) Photochem Photobiol66, 591–595) using time-resolved spectroscopy. In the present work, we have used the same experimental procedure to study the flavin semiquinone in rat kidney long-chain hydroxy acid oxidase and in the flavodehydrogenase domain of flavocytochrome b2 FDH

  • Penicilliumantifungal protein (PAF) is a promising antimycotic without toxic effects on mammalian cells and therefore may represent a drug candi-date against the often lethalAspergillusinfections that occur in humans. The pathogenesis of PAF on sensitive fungi involves G-protein coupled sig-nalling followed by apoptosis.

  • The eukaryotic class 1 polypeptide chain release factor is a three-domain protein involved in the termination of translation, the final stage of poly-peptide biosynthesis. In attempts to understand the roles of the mid-dle domain of the eukaryotic class 1 polypeptide chain release factor in the transduction of the termination signal from the small to the large ribo-somal subunit and in peptidyl-tRNA hydrolysis, its high-resolution NMR structure has been obtained.

  • Perry’s has been an important source for chemical engineering information since 1934. The significant contributions of the editors who have guided preparation of the previous editions is acknowledged. These include John H. Perry (first to third editions), Robert H. Perry (fourth to sixth editions), Cecil H. Chilton (fourth and fifth editions), and Sidney D. Kirkpatrick (fourth edition). Ray Genereaux (DuPont) contributed to each of the first six editions, and Shelby Miller (Argonne National Lab) worked on the second through the seventh.

  • Few of us can any longer keep up with the flood of scientific literature, even in specialized subfields. Any attempt to do more and be broadly educated with respect to a large domain of science has the appearance of tilting at windmills. Yet the synthesis of ideas drawn from different subjects into new, powerful, general concepts is as valuable as ever, and the desire to remain educated persists in all scientists.

  • England’s fisheries in 1871, Congress created the U.S. Commission of Fish and Fisheries (Hobart 1995). The first appointed Commissioner, Spencer Baird, initiated marine ecological studies as one of his first priorities. According to Baird, our understanding of fish “... would not be complete without a thorough knowledge of their associates in the sea, especially of such as prey upon them or constitute their food....” He understood that the presence or absence of fish was related not only to removal by fishing, but also to the dynamics of physical and chemical oceanography.

  • Subduction is a major process that plays a first-order role in the dynamics of the Earth. The sinking of cold lithosphere into the mantle is thought by many authors to be the most important source of energy for plates driving forces. It also deeply modifies the thermal and chemical structure of the mantle, producing arc volcanism and is responsible for the release of most of the seismic energy on Earth. There has been considerable achievements done during the past decades regarding the complex interactions between the various processes acting in subduction zones.

  • Over the past several years, the automobile industry has been in a period of dramatic turbu- lence. There have been large movements in gasoline prices, taking retail prices to their highest real values ever (Energy Information Administration, Short Term Energy Outlook, January 2007). The Ford F150 pickup fell from its longstanding position as the highest selling car in the U.S. in favor of the Honda Civic (Automotive News, June 5, 2008), while GM lost its position to Toyota as the worldwide leader in new car sales (Barron's, January 21, 2009).
