  • Natural gas is a vital component of the world's supply of energy and an important source of many bulk chemicals and speciality chemicals. It is one of the cleanest, safest, and most useful of all energy sources, and helps to meet the world’s rising demand for cleaner energy into the future. However, exploring, producing and bringing gas to the user or converting gas into desired chemicals is a systematical engineering project, and every step requires thorough understanding of gas and the surrounding environment.

  • Clinical Manifestations Intestinal Disorders Food Poisoning C. perfringens, primarily type A, is the second or third most common cause of food poisoning in the United States (Chap. 122). The responsible toxin is thought to be a cytotoxin produced by 75% of strains isolated from cases of foodborne disease. The cytotoxin binds to a receptor on the small-bowel brush border and induces a calcium ion–dependent alteration in permeability. The associated loss of ions alters intracellular metabolism, resulting in cell death.

  • VACUUM DISTILLATION TOWER In order to further distill the residuum from the atmospheric tower at higher temperatures, reduced pressure is required to prevent thermal cracking. The process takes place in one vacuum distillation tower. The principles of vacuum distillation resemble those of fractional distillation and, except that larger-diameter columns are used to maintain comparable vapor velocities at the reduced pressures, the equipment is also similar.

  • Global warming is the rising average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's average surface temperature has increased by about 0.8 °C, with about two thirds of the increase occurring since 1980. Warming of the climate system is unequivocal, and scientists are more than 90% certain that most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and the burning of fossil fuels.

  • Oil and gas are the most important non-renewable sources of energy. Exploring, producing and managing these resources in compliance with HSE standards are challenging tasks. New technologies, workflows and procedures have to be implemented.This book deals with some of these themes and describes some of the advanced technologies related to the oil and gas industry from HSE to field management issues. Some new technologies for geo-modeling, transient well testing and digital rock physics are also introduced. There are many more technical topics to be addressed in future books.

  • The confluence of market demand for greatly improved compact power sources for portable electronics with the rapidly expanding capability of micromachining technology has made feasible the development of gas turbines in the millimeter-size range. With airfoil spans measured in 100’s of microns rather than meters, these “microengines” have about 1 millionth the air flow of large gas turbines and thus should produce about 1 millionth the power, 10-100 W.

  • The discovery of Shigella as the etiologic agent of dysentery—a clinical syndrome of fever, intestinal cramps, and frequent passage of small, bloody, mucopurulent stools—is attributed to the Japanese microbiologist Kiyoshi Shiga, who isolated the Shiga bacillus (now known as Shigella dysenteriae type 1) from patients' stools in 1897 during a large and devastating dysentery epidemic. Shigella cannot be distinguished from Escherichia coli by DNA hybridization and remains a separate species only on historical and clinical grounds.

  • Turkeys should be finished and ready for processing at 12 to 24 weeks of age for old varieties and 12 to 18 weeks of age for newer, heavier varieties. Hens are usually processed at younger ages than toms. Turkey broilers or fryer-roasters are usually animals of the same strain used to produce heavier carcasses

  • 7 Health care For good productivity and profitability, you should keep your chickens as healthy as possible. Sick chickens do not produce, and profits will be lost if you have to buy medicines or if your chickens die. Prevention is better than cure, so try to provide good housing, nutrition and health care for your chickens, and observe them daily for any abnormalities and disease symptoms.

  • This framework sets out the general principles behind producing high quality performance information – that is information used to measure an organisation’s progress towards its objectives. It looks at what sort of information is worth collecting as performance information, and the principles behind pulling together a set of performance measures. It has been put together jointly by the National Audit Office, Audit Commission, Cabinet Office, Office for National Statistics and HM Treasury, reflecting common thinking of these organisations.

  • The industry is still improving technologically. It is far more mature than in 1993, and new developments appear poised to bring costs down further and to reduce the environmental impact of producing ethanol. In this report, we examine various production technologies, beginning with input improve- ments and then discussing process improvements, environmental technolo- gies, and technologies involving coproducts. Finally, we look at niche markets and briefly examine cellulosic conversion.

  • Probably the first commercial to make use of the newly invented principle of abstract composition was Walther Ruttmann’s ‘Der Sieger’, produced by Julius Pinschewer in 1922 for Excelsior tyres, where he adopted many ideas and motifs already present in his 1921 abstract work Opus 1. ‘Der Sieger’ was shot in black and white, coloured by combining toning with hand-colouring (cf Brinckmann, 1997: 263).

  • Measurement of efficiency started with Farrell (1957) who, following Debreu (1951) and Koopmas (1951), proposed a division of efficiency into two components: technical efficiency, which represents a firm’s ability to produce a maximum level of output from a given level of inputs, and allocative efficiency, which is the ability of a firm to use inputs in optimal proportions, given their respective prices and available technology. The combination of these two measures yields the level of economic efficiency.

  • Earlier automobile engine development produced a much larger range of engines than is in common use today. Engines have ranged from 1- to 16-cylinder designs with corresponding differences in overall size, weight, piston displacement, and cylinder bores. Four cylinders and power ratings from 19 to 120 hp (14 to 90 kW) were followed in a majority of the models. Several three-cylinder, two-stroke-cycle models were built while most engines had straight or in-line cylinders. There were several V-type models and horizontally opposed two- and four-cylinder makes too.
