´´Lasers is a remarkably well written book that should become the standard introductory text on laser physics.´´ Optical & Quantum Electronic News Lasers is both a text and general reference book with an emphasis on basic laser principles and theory. It gives a complete, detailed and accurate treatment of laser physics, building only on classical models, without requiring a quantum mechanical background of the reader.
The idea of engineering has been present since prehistoric times when humans started shaping important creations like the lever, wheel and pulley. Every invention is described with the contemporary explanation of basic engineering principles of mechanics. The word engineering has been derived from the term engineer and dates back to around recently 1325 and the word engineer in those times meant or denoted to someone who was the constructor of engines. The term engine has actually become obsolete as it is now refers to a military machine or in a more detailed description it was a mechanical apparatus used in wars. The word engine comes from the Latin word ingenium which means intrinsic quality, particularly cerebral power, as in an ingenious creation. As time passed more structures like houses, buildings and bridges were invented, which required new engineering techniques. The term civil engineering was introduced to differentiate among those who were experts in building military machines and was called military engineering. The term engineering is extremely broad and comprises a variety of different types of engineering, each focusing on specific parts of technology, applied science and applications. 1.

Oil industries in Nigeria play vital roles that are of great value and strategic towards supporting the nation´s development. Occupational hazards are conditions that arise from occupational environment in relation to industrial activities. Presently, the oil industry demands increased production, quality control, high efficiency, control of costs etc. The process involved in production has become complex and capital intensive. To meet these needs, occupational Health, safety and Environment becomes significantly important and when neglected, the consequence can be very costly. Thus, this book presented detailed information on occupational hazards that exist among workers in the oil industry in Rivers State, Nigeria. In addition, this book covered the following: Physical, Mechanical, Biological, Chemical, Psychological and most common hazards, and Occupational hazard control methods among oil company workers in Nigeria.
In the present work, the target station of the accelerator-driven neutron source HBS is optimized in comprehensive parameter studies using the Monto-Carlo method. The dependence of the most important performance characteristics of such a system on the external parameters is investigated neglecting technical and mechanical limitations. In this way, qualitative and quantitative statements for all possible configurations and envisaged applications can be derived and should be considered in the detailed planning of such facilities. For this purpose, different scenarios are considered that place completely different requirements on the design of the target station. The central statements derived in this thesis can be transferred to any framework conditions, such as different accelerator energies, so that these results can be used in the development of other neutron sources, which together with the HBS form a European network and provide a prosperous community in neutron science.
Introducing Human Design, the revolutionary system that reveals the personality ´blueprint´ of who you were born to be. Using the precise details of your birth, it´s more accurate than astrology. And with a free CD you can map your own life chart, and those of your friends and family. You´ll never read your horoscope again. Forget your sign, what´s your design? Would you like to know how to make the best decisions and follow your correct path in life? Would you like to know how you best interact with people, both professionally and personally? Would you like to know who you really are? Human Design is an exciting new profiling system that answers all these questions by pinpointing your personality ´blueprint´. According to Human Design, we are each born with an inbuilt individuality as unique as our fingerprint - accessed simply from the date, time and location of our birth. Using this information, Human Design produces a ´life chart´, revealing a remarkably detailed and accurate picture of your personality blueprint, including your strengths and limitations, people you work best with, how you communicate - in short who you were designed to be from birth. Chetan Parkyn, an ex-mechanical engineer, is the most successful practitioner of Human Design in the world. Here he launches his first book and CD as an introductory guide to interpreting your Human Design chart and how to apply it to your life to release your true potential. Once you know which of the 5 personality types you are, from there you can discover your detailed personality blueprint including: - whether you are designed with creative or organisational energy - your style of decision-making and how it can maximise your opportunities -how you interact with people socially or fit into a team at work - are you designed to be a guider or a follower - how you emotionally and mentally respond to challenges and problem-solving The power of the Human Design system is surprising thousands of people around the world with its staggering accuracy and relevance, and asks the question: Are you living your Human Design?
