  • To get around this restriction, many diesels incorporate an air pump in the form of an exhaust-driven turbocharger or a mechanical supercharger. Forced induction can double power outputs without violating the smoke limit. And, as far as turbochargers are concerned, the supercharge effect is free. That is, the energy that drives the turbo would otherwise be wasted out the exhaust pipe as heat and exhaust-gas velocity. The absence of an air restriction and an ignition system that operates as a function of engine architecture can wrest control of the engine from the operator.

  • Diesel engines, also known as CI engines, possess a wide field of applications as energy converters because of their higher efficiency. However, diesel engines are a major source of NOX and particulate matter (PM) emissions. Because of its importance, five chapters in this book have been devoted to the formulation and control of these pollutants. The world is currently experiencing an oil crisis. Gaseous fuels like natural gas, pure hydrogen gas, biomass-based and coke-based syngas can be considered as alternative fuels for diesel engines.

  • ‘Eco-procurement’ is already a key concept for operators, manufacturers and policy- makers, not least because railway rolling stock is often used for 30 years or more. Adherence to strict environmental performance specifi cations, including energy effi ciency, noise, diesel-exhaust emissions and recycling, must be considered when rail suppliers submit tenders.

  • The air pollution accumulating in the interior of automobiles consists almost exclusively of gaso- line and diesel exhaust. This toxic soup of gases, aerosols, and microscopic particles includes ben- zene (a known carcinogen), carbon monoxide (which interferes with the blood’s ability to trans- port oxygen), particulate matter (which studies have associated with increased death rates), and a host of other hazardous chemicals.

  • Changing or improving technology. Technologi cal improvements to vehicles are limited by local capacity to absorb the technology, which includes both turnover rates and capabilities for servicing and maintenance, and by the availability of fuel appropriate for the technology. Consequently, vehicle technology strategies need to be developed in response to particular local circumstances and in concert with fuel strategies.

  • Telch and Telch (1986) randomized 41 cancer patients with different diagnoses and stages of disease to a coping skills instruction group, an emotional support group or a no-treatment control group. The coping skills group showed consistent improvement in affective state, cognitive distress, communications, coping with medical procedures, and satisfaction related to work, social activities, physical appearance, sexual inti- macy, physical and social activities.

  • The diagnosis of breast cancer, the most common type of cancer amongAmerican women, elicits greater distress than any other diagnosis, regardless of prognosis (National Cancer Institute [NCI], 1997; Stechlin & Beach, 1966; Vinokur, Threatt, Caplan, & Zimmerman, 1989). The aim of this article is to shed more light on the relationship between quality of life and aspects of the psychosocial experience for women with breast cancer.

  • In a study of potential bone marrow transplant recipients, patients reported an improved outlook on life, enhanced relationships, and greater satisfaction with religious concerns (Andrykowski et al., 1993). The authors note that cancer should not be viewed as a homo- geneously negative event, but as a “psychosocial transition, i.e. an event with significant negative implications that can nevertheless cause individuals to restructure their attitudes, values, and behaviors, and thus can serve to trigger positive psychosocial change” (p. 274).

  • In recent years, legislative and market requirements have driven the need to reduce fuel consumption while meeting increasingly stringent exhaust emissions. This trend has dictated increasing complexity in automotive engines and new approaches to engine design. A key research objective for the automotive engineering community has been the potential combination of gasoline-engine specific power with diesel-like engine efficiency in a cost-competitive, production-feasible power train.

  • Particulate emissions from road transport arise as direct emissions from vehicle exhausts, tyre and brake wear and resuspension of road dust. In urban areas, emissions from road transport are thought to be the major source of PM10. In general, diesel engine vehicles emit a greater mass of fine particulate matter, per vehicle, than petrol engines. Diesel emissions are mainly composed of soot particles, volatile hydrocarbons and some sulphate from the fuel sulphur.

  • The literature indicates that the strongest concerns for women with early-stage breast cancer are those relating directly to cancer as a health and life threat, the most salient being the possibility of recurrence (Spencer et al., 1999). The experience of breast cancer often forces women to confront fear and uncertainty, and most overwhelming, the idea of their own mortality. These issues bring up many existential questions, for example “What is important in my life?” and “What meaning does my life have?”...

  • A greater understanding of inequalities is also crucial to recognizing the limits of what promoting positive mental health can achieve. Positive mental health does confer considerable protection and advantage, but it does so predominantly among those with equal levels of resources. In other words, among poor children, those with higher levels of emotional wellbeing have better educational outcomes than their equally poor peers. However, richer children generally do better still, regardless of emotional or cognitive capability.
