The unusual steep rise in the demand for LCD TVs in recent times evidently points to the growing faith in the LCD technology. However, the most puzzling question for many of us who are still unfamiliar with this new age techno-mania is : what is this techno -manic notion of the LCD and why is there so much frantic fervour for the numerous LCD technology-driven products in today’s market.

To begin with, the digitally-rich LCD technology functions smoothly by utilising the properties of polarised light. The reason behind the increasing dependence on this digital-mantra is its flawless performance. Hence, the LCD technology is increasingly being optimised in a vast number of electronic gadget items for instance, laptops and computer monitors and touchscreen devices like smart mobile phone handsets and digitally loaded gaming consoles.

In fact, a recently concluded survey interestingly enough, revealed the sharp shift in the choices and dispositions of today’s customers. The LCD TVs in India are increasingly being preferred by the customer’s as these are replacing their yesteryears’ favourite CRT television sets. A lot of factors such as:creation of a strong market base, a change in customer’s preferences, rise in the prospective customer’s income, healthy competition between rival firms, positively influencing market trends and favourably disposed government policies – have given the required push to the market of LCD TVs.

Just in case you are wishing to strike a deal for one of these high-class yet cheap LCD TVs in the Indian market then a few criteria should be borne in mind by all discerning customers such as the prospective users should critically study a product on the yardsticks of quality, functionality, performance, availability of substitute products in the market.

As a matter of fact, Samsung LCD TVs are currently in hot demand. Samsung, the giant company that deals in digitally- rich cheap LCD TV has recently launched a new series of LCD television sets to suit the requirements of their Indian clientèle. Some of these LCD TVs in Indian market include the Samsung LA26R71 (Bordeaux), Samsung LA32S8 (Sonoma Trenz) and the Samsung LA19R71(Bordeaux). These Samsung LCD TV come with the promise of offering world class entertainment at very affordable price. So, without having to worry about the expenses one can strike a “safe” deal for these sophisticatedly designed high-end home entrainment electronic gadgets.

Digital signage is now the new must-have marketing tool with its applications and uses having multiplied many-fold over the last few years with LCD and plasma screens now being seen in all manner of locations for all manner of uses.

One of the latest environments to be exploited for the purposes of digital advertising is the use of plasma and LCD screens outside.

Digital outdoor signage is one of the few niche areas left in the digital marketing industry but more and more companies have spotted the potential and are producing LCD TVs that can be situated outdoors.

The major challenge of outdoor digital signage is protecting the plasma or LCD display from the elements. Many manufacturers ensure their outdoor LCD or plasma is sealed to protect from the rain which is obviously highly important when it comes to outdoor signage. However, many of these outdoor LCD screens are manufactured for mild climates and little consideration is given to the varying extremes of temperature often found in Europe and North America.

Extreme heat in the summer can be extremely damaging to an LCD. Both the screen and the electronics of the LCD need to be protected from the sun. LCD screens are easily damaged by direct sunlight while without adequate cooling exposure to high temperatures will dramatically shorten an LCD or plasma’s lifespan.

Likewise protection from the cold is highly important as most LCD’s will simply not be able to cope in temperatures below zero.

However, many manufacturers are starting to identify these outdoor hazards and are producing LCD’s designed to operate in extreme temperatures. However, most of these outdoor digital signage solutions are targeted at a particular environment such as extreme cold or extreme heat. There are very few options available that can actually deal with the heat of summer and the freezing temperatures often endured in parts of America and Europe during the winter months.

Fortunately, for those of us that live in areas where both extremes of temperatures are often experienced throughout the year a smarter more practical solution is to use standard LCD displays and house them in an outdoor LCD enclosure. LCD enclosures (and plasma enclosures) are now manufactured by some industrial computer enclosure manufacturers who use their experience of housing computers and touch screens in industrial areas to build LCD enclosures that can cope with not just the rain but all extremes of temperature and weather.

These steel LCD enclosures are also built to withstand vandalism and theft allowing the outdoor digital signage to be left unattended with full peace of mind.

The human heart consists of four valves: the mitral valve, the tricuspid valve, the pulmonic valve and the aortic valve. These valves direct blood from and to the body throughout the heart. A defect, disease, damage or infection of the heart leads to the malfunction of any of the four valves. The severe malfunction of a heart valve gets in the way of the blood flow. It also causes fainting spells, heart palpitation and difficulty breathing. These physical conditions worsen and may threat life with death if the damaged valve is not replaced timely.

 

How The Surgery Takes Place

The surgeons first of all, cut through and separate the ribs and breastbone. Then the patient is placed on a cardiopulmonary bypass machine. This machine will carry out the functions of the lungs and heart during the execution of the surgery. Then, the surgeon cuts open the heart to locate the position of the damaged valve. They loosen the valve from the connecting tendons by slicing around the valve. The place of the damaged valve is filled up with a new valve.

 

Different types of valves

Replacement valves are of three types. One is made of animal tissue, especially the aortic valve of a pig. The second one is mechanically made of plastic and metal. The third one mainly includes the valves of human heart. This valve is removed from the body of an organ donor.

 

Normal Results

Majority of heart replacement cases turn up successfully. Only a few patients die on account of the surgery. The percentage of patients who die during or after the surgery is very low. Percentage of patients who are under 65 and who die on account of the surgery is less than 1. However, the quality of life is improved after the surgery in successful cases.

 

Double Valve Replacement – The Ross Procedure

“Double Valve Replacement?!” you may be thinking to yourself, “Why a double valve replacement if only your aortic valve was problematic?”

It’s a great question you raise. It seems very logical that only having one aortic valve replacement surgery would and should be necessary. So, why a double valve replacement ? Enter Dr. Donald Ross, the inventor of the Ross Procedure operation.
