EC1403 MICROWAVE ENGINEERING UNIT-1 - BASIC MICROWAVE COMPONENTS INTRODUCTION TO F MICROWAVE ENGINEERING Modern electromagnetic theory was formulated in 1873 by James Clerk Maxwell solely from mathematical considerations. Maxwell’s formulation was cast in its modern form by Oliver Heaviside‚ during the period 1885 to 1887.Heinrich Hertz‚ a German professor of physics understood the theory published by Maxwell‚ carried out a set of experiments during 1887-1891 that completely

2-diphenyl-1‚2- ethanediol Discussion and Conclusion One can ascertain from the H NMR the stereoselectivity taking place in the reaction. Since there is not coupling of the Hc’s on product B‚ one can assume that they are in a similar environment‚ thus deducing that they are on the same side‚ forming a meso molecule. The doublet of doublet formed by coupling of the methyl groups shows that they are in different environments too‚ strongly implying that the phenyl groups are likely both on one side‚ supporting

carboxylic acid‚ a salt of the organic acid and base is obtained. To overcome this‚ the carboxylic acid first needs to be "activated". This is usually done by converting the acid into a more reactive derivative (i.e. anhydride‚ acid halide) or by using a coupling agent. In some cases‚ high temperatures (>200 °C) can overcome salt formation by driving off water‚ without the need for "activation" of the carboxyl group. The downside to this simple reation is that the compounds may decompose at these elevated

PERTH COLLEGE UHI 12 INSTRUMENTATION OF A WIND TUNNEL PROJECT BEng(Hons) Gaurab Ghosal ABSTRACT The wind tunnel being built in Scone airport is a closed loop wind tunnel. On completion this will provide a much needed facility for education purpose as it can be used by engineering students for aerodynamic evaluations. To conduct these evaluation proper evaluating tools needs to be setup. In this section the possible instruments that can be setup in this wind tunnel has been evaluated with

2003‚ the Cameron situation returned to normal‚ although there was a need to invest in a new plant to separate the line of production of flexible couplings. As Cameron was not financially prepared to make that commitment‚ the options were either to wait a year to generate more profits and financial stability‚ or license production of the flexible coupling. In the spring of 2004‚ Alex signed a five-year agreement with licensing Supplies Ltd. McTaggart. McTaggart had to pay $ 100‚000 in fees in advance

Synesthesia is a neurological condition in which at least two senses are intertwined. Normally‚ a sensory input is perceived and handled by one modality of the brain. In synesthesia‚ it was presumed that a sensory input in one modality directly elicits an additional sensory activation in another sensory modality. The original perceived sensation is called the inducer and the additional perception is called the concurrent. So‚ for example‚ someone with synesthesia may see a certain letter of the

pipes or tubes in which fluids enter. It consists of two streams one for hot water and the other for cold water. The heat exchanger also consists of a control valve which is used to regulate the volume and mass. It also consists of cooling water couplings which are used to switch the cooling water direction from counter current to concurrent and vice versa. Introduction A heat exchanger is used in many different applications in a wide range of fields. The importance of a heat exchanger is to transfer
