This textbook includes four chapters. The first chapter which entitles Introduction to English for Science and Technology reviews the scientific English from the viewpoints of: basic definitions, the purpose of using it as a communication language, its importance, how technology is used for learning English, and differentiation between science and technology.The second chapter which entitles Glossary of Mechanical Engineering discusses include the following items: Introduction to Mechanical Engineering, Types or Sub-disciplines of Mechanical Engineering, and Mechanical Engineering...

The textbook presents a brief outline of the basic engineering in performance test of diesel engine using ethanol-diesel fuel blends. The study has been taken from the point of view of introduction, literature review, experimental work, conclusions and recommendations. Ethanol is an alternative energy source. It is alcohol made by fermenting corn other similar biomass material. Ethanol in its liquid form, called, ethyl alcohol, can be used as a fuel when blends with diesel, or gasoline or in its original state. It can also be used as a raw material in various industrial processes. Ethanol is...

The diploma in mechanical and production engineering has been developed as a cooperative venture between Leeds Polytechnic of U.K. and the Mechanical Engineering College Atbara of Sudan, under the auspices of the British Council. The Mechanical Engineering College Atbara has offered a 3-year course in mechanical engineering since 1971. This current course is a logical development of the previous course, and maintains as its overall objective, the education of technician engineers to a level of practical and academic competence compatible with that of Western Europe and satisfying the...

La corrosion est un processus naturel qui transforme un métal raffiné en une forme plus stable chimiquement, comme un oxyde, un hydroxyde ou un sulfure. C'est la destruction progressive des matériaux (généralement un métal) par réaction chimique et/ou électrochimique avec leur environnement. L'ingénierie de la corrosion est le domaine consacré au contrôle et à la prévention de la corrosion.Dans les environnements aqueux, les métaux peuvent être exposés non seulement à une corrosion uniforme, mais aussi à divers types de corrosion locale, notamment la corrosion par piqûre,...

This study aimed at increasing ships' power and performance by protecting its hull from corrosion and bio-fouling which cause reduction of the vessels power. The study is based on four assumptions. First, the vessels hulls should be protected from corrosion to increase their power and performance. Second, vessels hulls corrosion can instantly be controlled using Impressed Current Cathodic Protection 'ICCP'. Third, coating has a great effect on protecting vessels hulls and increasing their performance. Finally, there are many factors that contribute on ships' hull corrosion. The data were...

Engineering is the profession in which knowledge of the mathematical and natural sciences gained by study, experience, and practice is applied with judgement to develop ways to utilize, economically, the materials and forces of nature for the benefit of mankind.Mechanical engineering is one of the most diverse and versatile engineering fields. Mechanical engineering is the study of objects and systems in motion and static states. As such, the field of mechanical engineering touches virtually every aspect of modern life, including the human body which is a highly complex machine.The role of a...
