  • There are few physical phenomena so generally studied which are as misunderstood as the phenomenon of flight. Over the years many books have been written about flight and aeronautics (the science of flight). Some books are written for training new aeronautical engineers, some for pilots, and some for aviation enthusiasts. Books written to train engineers often quickly delve into complicated mathematics, which is very useful for those who wish to make detailed calculations.

  • The classic text on helicopter aerodynamics, "Aerodynamics of the Helicopter" has been in continuous print for over fifty years. Clearly written and well illustrated, the book focuses on fundamental physical relationships without a highly complex mathematical development. The emphasis on fundamentals makes the book an ideal - indeed, necessary - first step towards more advanced study.

  • In section 2, there is an illustration of the source and types of industrial contaminants in many parts of the world. It is essential to understand the characteristic of industrial discharge in order to have an idea for ways to reduce or remove the contaminants for a sustainable tomorrow. It is required to understand the impacts of industrial waste to the environment (freshwater, seawater, land) in order to design highly efficient treatment and developing effective remedial methods.

  • It’s important to understand why some funds target operating in the green zone, and why other funds may intentionally operate in the yellow or red zones. The green zone calculus is simple: when a fund maintains fixed expenses that are lower than its fixed revenues, it operates with a margin of safety. In a green zone fund, both the fund and its investors have a reasonable cushion to ride out difficult periods of low or no performance, and the fund operates with less business risk. In other cases, a manager may wish to operate in the yellow or even red...

  • The term ―luxury‖ is routinely used in our everyday life to refer to products, services or a certain lifestyle, however, often without a clear understanding of the luxury concept as it takes on many different forms for different people and is dependent on the mood and experience of the consumer: ―Luxury is particularly slippery to define. A strong element of human involvement, very limited supply and the recognition of value by others are key components‖ (Cornell 2002, p. 47). The word luxury ―defines beauty; it is art applied to functional items.

  • Greenplum’s SG Streaming™ technology ensures parallelism by “scattering” data from all source systems across hundreds or thousands of parallel streams that simultaneously flow to all Greenplum Database nodes (Figure 11). Performance scales with the number of Greenplum Database nodes, and the technology supports both large batch and continuous near-real-time loading patterns with negligible impact on concurrent database operations.

  • Rigorously speaking the functional group is not the whole molecule but only that collection of atoms that provides a specific chemical function. For example, the chemical family of alcohols is characterized by the function of the hydroxyl (OH) group, and aldehydes, ketones are characterized by carbonyl groups (C=O). There are various combinations of hydroxyl groups in molecules along with carbonyl groups and these combinations can lead to hydroxyketones and aldehydes (the basis for sugars) as well as to carboxylic acids.

  • The field of astronomy and astrophysics has advanced significantly with the advent of orbiting observatories. The ability to observe unobstructed by Earth’s atmosphere has opened new spectral windows and provided clearer, deeper views of the universe. Working with powerful new ground-based tools, astronomers and astrophysicists have revolutionized our understanding of the universe and the physical laws that govern its existence.

  • Flight plan: • In this lesson we will review all the numerical data types offered by the MPLAB® C30 compiler. • We will learn how much memory the compiler allocates for the numerical variables and we will investigate the relative efficiency of the routines used to perform arithmetic operations by using the MPLAB • SIM Stopwatch as a basic profiling tool. This experience will help you choose the “right” numbers for your embedded-control application, understanding when and how to balance performance and memory resources, real-time constraints and complexity....

  • To provide appropriate health care to this group GPs and health professionals must be aware of the pre-migratory and ‘flight’ experiences. An understanding of the patients’ history is essential if an appropriate response is to be formulated. For example in the case of victims of torture, medical professionals need to develop the ability to recognise physical signs which would indicate that torture has occurred.
