Landscaping
It is an art which deals with conscious arrangement or
organization of outdoor space for human satisfaction and
enjoyment.
Some of its major goals include :-
Organizing and developing the site for maximum use and pleasure.
Creating a visual relationship between the house and the site.
Reducing landscape maintenance to a practical level.
Dealing with health and stress management, energy conservation,
noise
control, erosion control, pollution control.Page 3

Solidstate lasers can produce lightin red and blue parts of the visiblespectrum, generating laserlight in all colours except green. Butrecent research work suggests thatthis ‘green gap’ could be plugged.New techniques for growing laserdiodes could soon make brilliant fullspectrumdisplays a reality.Plugging the green gap in the redgreen-blue triad needed for full-colourlaser projection and display wouldhelp speed the introduction of laserprojectors for televisions and movie theatres, which will display much richercolour ....etc

Thermal Barrier Coatings

Heat engines are based on considering various factors such as durability, performance and efficiency with the objective of minimizing the life cycle cost. For example, the turbine inlet temperature of a gas turbine having advanced air cooling and improved component materials is about 1500oC. Metallic coatings were introduced to sustain these high temperatures. The trend for the most efficient gas turbines is to exploit more recent advances in material and cooling technology ....etc

ABSTRACT

The concept of insulating cooled heat engine components such as gas turbine blades and diesel engine valves from hot working fluids with a ceramic thermal barrier coating is by no means new. A practical system, however, has only been identified in the past few years. Thermal barrier coating (TBC) are applied to metallic components to reduce metal temperature, reduce life cycle cost, increase the environmental resistance and in some cases reduce noxious exhaust emissions. The selection of TBC involves many consider ....etc
