Understanding Data Loss and Data Recovery
Losing data is the worst thing that can happen to someone who is too attached to computers. It is not a question on "how attached" a person is, it is a question on how much a person earns out of his data. In other words, for beginner computer users, losing files is like losing common documents, but for developers, it means losing source files. Source files are projects developed with the use of certain complex application. Losing them is close to losing a career!
Data recovery is the solution to lost files. Data do not just disappear in one click but some of them are stored and could be recovered. The means of data recovery depends on the diagnostic and troubleshooting on how the functioning of the computer started.
It is not easy to determine problems in the computer for a novice, but for experts, events with PC sounds, speed change, temperature and booting problems are just some signs and symptoms of a lingering problems which could lead to data loss. Corrupt files occur when there is direct disturbance changing the data properties. When a project file can't be opened, it is possibly corrupt. Latest softwares have the capability to recover files in one execution.
Simple documents have high potential possibility of destruction. Complex applications involving vectors with larger project files, when corrupted, have the least chance of recovery. Examples of which are computer aided design applications, graphic arts editor, video editors and programming applications.
What are the kinds of flaws that trigger data loss?
Physical Defect Of Peripherals - hard disk damages show signs of file corruption before affecting the raw data. Upon knowing the sign of hard disk failure, it is important to make back-ups to avoid losing current and past data. Accidents and unavoidable circumstances can also cause peripheral damages in a PC, which can lead to data loss.
Overheating of the CPU can lead to chain reaction and shut of the computer. Constant crashing without proper shutting down procedure is one of the harshest of data destroyer. Usually the current file being worked on before the big crash happened is the one rendered useless afterwards.
Virus Attack - computer intruders will not give computers any benefit. Virus is always created to destroy data. By installing an effective anti-virus, this problem can be avoided or can be resolved easier than not having one. Careless downloading of any freebies in the Internet is harmful. It is important to understand how adwares can harm your local file in just one click. Virus propagators in the net are using advertising tools to gain access remotely to any private data.
On the onset of viral attack, do not do anything in the computer or leave it on any further. The more it is left functioning, the more the virus will spread and destroy the system. If you suspect your PC has been attacked, give it an instant cold boot. Do not use it unless the purpose is data recovery and diagnostics.
Accidental Format - A person could be too drunk booting the PC and accidentally executing the format command! Formatting is the greatest mortal sin one can execute to a disk rich with important data. It is the last resort when a disk has too many garbage needing a good overhaul. Formatting a disk is erasing the entire disk for good. Some good utilities have means to UNFORMAT and regain back the lost data in a formatted hard disk.

Molten Splash Protection for EAF Power Cables
The Problem
When a water cooled power cable is used in severe environments such as powering an EAF (electric arc furnace) in a steel mill, there is an enormous potential for heat, flames, ash or molten splash to damage the electrical cables (or series of cables) thus crippling the melting operation. This damage translates into unscheduled maintenance and lost production time. In some instances these costs have been estimated as high as $100,000 per hour, depending on the size of the operation and production schedules.
Water-cooled power cables provide a flexible source of power to permit movement of the electrode arms up and down, and to allow swinging the electrode arms and roof back and forth when charging the furnace. A low temperature rubber jacket allows cooling water to flow around the outside of the cable assembly.
Given the large diameter of the rubber jackets surrounding the power cables and proximity to the EAF, there is a significant landing area for sparks, molten metal splash, etc. In many applications the cables are left completely unprotected, exposed to severe high temperature environments. In other cases the rubber cooling water hose is wrapped with inexpensive fiberglass tape that offers minimal protection against possible hazards.
The danger is that molten metal splash caused by “wet charges”, flame impingement, or extreme heat will damage the power cables. This can cause a chain reaction of catastrophic events, including loss in water cooling resulting in overheating or shorting of the electrical power cables and halting the melting process.
The Solution
Wrapping a new or existing water cooled power cable assembly with a severe duty protective molten splash sleeve is the way to prevent damage from heat, flame, ash and large intermittent exposure to molten metal splash. A product manufactured and designed with 100% non-conductive materials specifically for safe non-arcing use in close proximity to AC or DC EAF’s will serve the purpose more successfully than ineffective fibreglass tape, or rubber jackets alone.
A thick silicone coating on a high temperature fiberglass substrate sheds large, random, but potentially hazardous amounts of 3000˚F molten metal splash by virtue of its hydrophobic, low surface energy, non-stick properties. Such a coating helps maintain the integrity of the water cooled power cable until the next scheduled maintenance period. Equipped with a hook and loop self gripping closure, the molten splash away sleeve is easily field installed (or removed for maintenance) without cable disconnection, but also ensures the closure doesn’t separate during severe bouncing and bumping of cables during furnace arc and cold starts.
Depending on the application, the cost to procure and install a high temperature jacketing system could be as low as $30 per foot. Relative to the enormous costs associated with unscheduled maintenance and lost production time, this capital investment could pay for itself several times over with the prevention of a single unscheduled maintenance event.

Can video conferencing reduce the rate of climate change?
Global warming has been a subject that most of us have grown up hearing about, it has been a concern for some for many years but it appears to have been thrust into the limelight in recent years. Many of the world’s politically sensitive governments and prominent scientists have all started to take notice of the extreme weather conditions that are starting to plague our planet, they are talking more seriously about solutions and action that needs to be taken NOW to ensure our world’s health.
CO2 production is at record levels; there is a large amount of resources that are wasted on a daily basis and now is the time to take action. It is very simple to think to ourselves that we, as individuals, cannot do anything about the collective polluting and the wasting of resources but of course we all know change is a gradual process brought about by individuals changing their behaviour. You and I make the difference, if we all started to think about how we effect the planet with our actions, global warming can be slowed and may even be reversed. If we assume that all is lost no-one will try to change, we have to take responsibility both in our business lives as well as our private lives. Eyenetwork offers a solution to the huge amount of unnecessary business miles that add to the huge CO2 output we generate. Every year thousands of air miles are spent attending business meetings abroad that could be more easily carried out using the high quality
video conferencing technology that is available from Eyenetwork.
Sophisticated equipment is available to enable anyone anywhere to organise and hold a business meeting, seminar or training session without leaving the office. Video conferencing and audio conferencing can be used for many different purposes:
• Giving evidence to Magistrates or Crown Court
• Casting for television production
• In house business presentations
• Global environmentally friendly conferencing
• Product training for employees and clients
• Sales representations and product launches
• Design and creative assessment, project liaison
• Business to business consultancy services
