<p>The Maldives is a remarkable tropical destination, loved by all who visit. Read about the amazing beauty of the Maldives holiday islands and how time may be running out for this paradise in the Indian Ocean.<br />r<br />rParadise Found<br />r<br />rWhen you step outside of the airport in Male you will be struck by the warmth of the air and the strength of the sun. You will likely want to take a cold drink in the shade of a nearby cafe as your transfer is organised and the bus is boarded. For those taking a seaplane transfer, the flight from Male to your island resort is the first treat of Maldives holidays, providing a special view of the country. From the air you can appreciate the way these sandy islets spring from the shallow sea, and see the shape of the atolls and reefs below the surface of the water.<br />r<br />rThe beaches here are miraculous. By wading out just a few metres into the water you can find fish swimming around your legs, so snorkelling here is a delight, too. It is usual for the Maldives resorts to stage feeding displays once a day. This gives you a chance to view the fish that live around the island as they scramble to gobble up what is dropped into the clear shallow water from the piers or wooden walkways.<br />r<br />rOne of the more outlandish fish you can see is the guitar fish, which is a species of ray. It has a square box head and body with a long slim tail so it resembles a guitar from above; however, from the side it is easily mistaken for a shark, having a similar silhouette. So a guitar fish may get your digital pulse oximeter racing if you see it while you are Scuba diving.<br />r<br />rWith clear, warm water and shallow sandy sea floors around the islands, Maldives holidays are excellent for learning to Scuba dive, and most Maldives resorts have their own diving schools. If you are PADI accredited, you can venture to the dive sites beyond the reef shelf. There you’ll find the deeper water where the coral reefs are festooned with colourful and vibrant sea life. You might see turtles, eels, small sharks, and a dazzling array of brightly decorated tropical fish.<br />r<br />rParadise Lost?<br />r<br />rThe waters that make Maldives holidays so special may soon bring an end to the luxurious lifestyle here. The Maldives is famously one of the many beautiful locations in the world that are under threat owing to climate change. Amazingly, the highest point in the country is only about six feet above sea level, so as the oceans rise because of global warming, the islands are vulnerable to flooding.<br />r<br />rPresident Maumoon Abdul Gayoom of the Maldives has talked about purchasing more land for his countrymen, worried that they will become refugees as the land is depleted in future decades. At the moment though, the country is a paradise, and the Maldives resorts are some of the finest in the world.<br />r<br />rTime may be running out to take Maldives holidays in the lowest country in the world, and this impermanence makes these island gems seem even more precious, with the knowledge that in a few decades they could be sunken treasure.</p><br /> rtime can expect to travel to the Maldives in the last country in the world, and this variability makes the stones of the island, more precious to say with confidence that within a few decades, they can be a treasure. </ P>

The LCD TV is an incredibly flexible device. The flat panel TV’s that have now all but replaced the bulky CRT monitors of yesteryear can be mounted against a wall and are ideal for digital signage and information purposes.

LCD and plasma screens have even been adopted in factory and industrial areas as they provide a far more convenient a solution for monitor and display needs than CRT monitors.

Although, LCDs are not designed for these types of areas as most flat panel TVs are built and manufactured for home use only.

Many factory elements such as dust from warehouses and packing locations to water used in wash down locations can easily permanently damage a modern LCD TV.

Enclosing the LCD is one solution to allowing their use in these sorts of areas but an LCD enclosure needs to take into account several issues.

Firstly, as with most electrical devices, airflow needs to pass through the LCD TV to keep the device cool. Normally speaking this is done by the use of filters but in a factory setting these filters will soon become clogged with dust.

An LCD enclosure gets around this by using appositive pressure system allowing air to flow through the enclosure and LCD whilst also keeping the dust out.

Another consideration with using LCD’s in factory settings, especially in food production areas, is the amount of water used. An LCD enclosure uses special shaped chambers known as plenum that allow airflow up through the enclosure but prevents any water, even from hose-down, penetrating the enclosure therefore providing waterproof protection for the LCD.

Temperatures can be another concern in factory settings especially in chillers or near furnaces where extreme temperatures on either end of the scale can cause a permanent failure of the LCD. An LCD enclosure ensures optimum operating temperatures at all time by utilising thermostatically controlled heaters and additional cooling systems allowing the LCD to operate in temperatures as low as – 30 degrees centigrade and as high as + 50.
