Water saver

They re the latest in high-tech faucetry hands-free water-savers, equipped with electronic-eye sensors that automatically detect hands and dispense preset amounts of water. They re also more likely to be contaminated with one of the most common and hazardous bacteria in hospitals compared to old-style fixtures with separate handles for hot and cold water, according to researchers at Johns Hopkins Hospital. 

So-called water savers are cooling-water exit-temperature controls. They have the advantage of rninimizing cooling-water flow rate for any given heat load. Their use also minimizes subcooling—and there are instances where this is desirable—but at the expense of variable condensate temperature. This can cause variable internal reflux unless it is compensated for (see Chapter 11, Section 2). This kind of control is often implemented as shown in Figure 3.7 pressure is controlled by manipulation of makeup and vent valves. 

One novel method for scale control is magnetic and electrostatic technology suggested by US Department of Energy [22]. This nonchemical technology is recommended for scale and hardness control as a reliable energy saver in certain applications that can be used as a replacement for most water-softening equipment. 

Polyolefins, other synthetic polymers, and water-soluble macromolecules have been investigated in highspeed SEC systems. High-speed SEC can be a major time saver in two-dimensional chromatography applications, which require about 10 hr analysis time for cross-fractionation. This can be reduced by a factor of 10, to about 1 hr, which makes it much more interesting for many laboratories. Details on these and additional highspeed applications can be found in Ref. [4].

Textile materials are materials for the daily use. Besides, textiles are also play a vital role in fashion shows. Technically, they are applied in variety of our life savers including safety belt, and the airbags in the cars, bulletproof vests protect against weapons, used as Implant material in medical applications. Recently, pol3mrethane (PU) foams that can be combined with Platilon thermoplastic pol5mrethane (TPU) films are used as excellent material for functional medical wound dressing which are not only help wounds to heal but also allow the wound to breathe by permeate the water-vapor [70, 71].
