ARCHITECTURE |
|
Architecture (from Latin, architectura and ultimately from Greek, αρχιτεκτων, "a master builder", from αρχι- "chief, leader" and τεκτων, "builder, carpenter")[1] is the art and science of designing buildings and structures. A wider definition would include within its scope the design of the total built environment, from the macrolevel of town planning, urban design, and landscape architecture to the microlevel of creating furniture. Architectural design usually must address both feasibility and cost for the builder, and function and aesthetics for the user.

COOLING TOWERS |
|
Cooling towers are structures for cooling water or other working medium to near-ambient temperature. The primary use of large, industrial cooling towers is to lower the temperature of the cooling water used in power plants, petroleum refineries, petrochemical plants, natural gas processing plants and other industrial facilities. It is desirable to cool the water rather than simply discharging it because the cooling water is typically demineralized and it is cheaper to cool it rather than getting more demineralized water. Furthermore, discharging large amounts of hot water may raise the temperature of the receiving river or lake to an unacceptable level for the local ecosystem. A cooling tower serves to dissipate the heat into the atmosphere instead and wind and air diffusion spreads the heat over a much larger area than hot water can distribute heat in a body of water.

PHOTOGRAPHY |
|
Photography is the process of making pictures by means of the action of light. It involves recording light patterns, as reflected from objects, onto a sensitive medium through a timed exposure. The process is done through mechanical, chemical or digital devices commonly known as cameras.
The word comes from the Greek words φως phos ("light"), and γραφις graphis ("stylus", "paintbrush") or γραφη graphê, together meaning "drawing with light" or "representation by means of lines" or "drawing." Traditionally, the product of photography has been called a photograph. The term photo is a convenient abbreviation. Many people also call them pictures. In digital photography, the term image has begun to replace photograph. This term is neither more nor less correct than photograph, either in film or digital photography. (The term image is traditional in geometric optics.)
