JAN. 3, 2013 - Myanmar celebrates today its Independence Day, which commemorates the country’s freedom in 1948. Usual celebrations include a seven-day fair at Kandawgyi Lake in Yangon.

Myanmar is endowed with rich natural resources. It has approximately 250 commercially useful kinds of trees. Mineral deposits include lead, zinc, tin, tungsten, coal, iron core, natural gas, and petroleum, as well as deposits of precious stones such as rubies and lapis lazuli. The government is opening up its economy, and has intensified its economic cooperation with its ASEAN neighbors as well as with China and Japan.

Several agreements have been signed between the Philippines and Myanmar. They include a Memorandum of Understanding on a package of Assistance for Human Resource Development for Myanmar, a Memorandum of Understanding on Visa Exemption for Holders of Diplomatic and Official Passports, an Agreement for the Promotion and Reciprocal Protection of Investments, and an Agreement on Cultural Cooperation.

On June 15, 2012, the second Joint Commission on Bilateral Cooperation (JCBC) between the Philippines and Myanmar was held. The JCBC serves as a venue to discuss areas of mutual interest at a ministerial level. The Foreign Affairs Ministers of the two countries met and discussed political cooperation, trade and investments, education, human rights, agriculture and forestry, tourism, culture and information.

At the 29th Chaos Communication Congress (29C3) in Hamburg, Berlin-based security researchers Karsten Nohl and dexter presented a custom-built workstation for "microprobing" semiconductor chips. Comparable in-depth analysis tools such as those for microcontrollers and similar small computer systems often cost several tens of thousands of pounds and have so far mostly only been available in specialised labs. This type of analysis involves examining a chip's individual conductor wires or memory cells with a microscope-like setup and a very thin probe. The "probing device" enables examiners to, for example, record data and command sequences by intercepting bus signals.

Dexter explained that the custom-built workstation consists of a fixed-position microscope that can cope with large working distances to what it is working on, a large magnetic work platform, and a micropositioning system. The micropositioner is a motor-driven stage that can be moved in increments of a few millimetres to a few centimetres. Hardened tungsten needles are required on the microscope's tip to create the electrical contact with the semiconductor material. According to Nohl, who runs Security Research Labs, the overall component cost is no more than €3,000 (approximately £2,440) and will, for the first time, allow interested amateurs to do "microprobing in their basement".

The presented workstation uses a movable stage and micropositioner to place the chip that is to be examined underneath the fixed-position microscope's lens barrel; a tungsten needle is used as a probe Zoom.

This is a setback for the LED movement, which thought it had cast tungsten lighting into history.

The EBU has warned that the post-production color correction costs required for video shot under LED lighting could outweigh the power savings compared with traditional tungsten lights. This is a setback for the LED movement, which thought it had cast tungsten lighting into history as a result of not just of the greatly reduced energy consumption but also other advantages, notably lower maintenance and heat production.

With LED technology, about 80 percent of the electrical energy is converted into light, compared with 20 percent or less for tungsten bulbs, which emit most of the rest as heat or infra red radiation. The issue, though, has been in matching LEDs to the well-known light profile of tungsten bulbs, which the industry had thought it had solved. In the U.K., the BBC has been experimenting with LED lighting for production for more than three decades, and has recently used it on the sets of popular shows such as the hospital drama "Casualty." The BBC says it has developed tests that assess the color rendition of low energy light sources, and has stated it wants to send a clear message to the broadcasting community and to its viewers about the leading role that LEDs play in sustainable low energy production helping meet targets for reduced carbon emissions.

There has been similar enthusiasm for studio LEDs elsewhere, and they have been used in the U.S. for filming popular prime-time reality TV competitions such as "Dancing with the Stars," "America's Got Talent" and "American Idol."

But now the EBU suggests it may be premature to embrace LEDs fully in the studio, even if they are now ready for the home. Problems that have been identified include inconsistencies between factory batches, insufficient brightness and inability to spotlight subjects, especially from a great distance. A further issue is that color LED lights are prone to color shifts and inconsistencies that can be especially evident when lighting people's faces.

The EBU is not suggesting broadcasters should avoid LEDs, but urges them to recognize that many new LED lights fail to perform as well as had been expected or promised. The EBU has come up with its own recommendation to help broadcasters assess how well their television lighting performs. Called R 137, and accompanied by a software-based analysis tool, this is designed to quantify how well a set of test colors is reproduced when illuminated under a given light and viewed through a standardized camera and TV system. The software compares the differences in colors produced by the light source under test with those rendered under standard lighting conditions. It assigns a value from 0 to 100 to each light tested, and that value gives an indication of how much color correction would be required to produce acceptable results with that light.

In addition to the value assigned to the light, the software also provides additional information that can be used to advise colorists on how much correction is needed. In cases where the value assigned to a light is less than 50, the results may still be unacceptable, even given a lot of correction.

This procedure is likely to be only required for a temporary period while the LED lighting industry continues to improve and refine its products. LED lighting will indeed be ready for prime-time production, but as so often with emerging technologies, not quite as soon as everybody hoped or manufactures led us to believe.

2013 is here and this is my our year. Well, maybe not year, but in two months, I will be taking that walk down the aisle, looking my honey in the eye as I say:

“I Do.”

Those two words are what every little girl dreams of saying to and hearing from her Prince Charming, as she stands in front of her family and friends on one of the biggest days of her life. However, the road to the alter isn’t always one of bliss; a lot of planning goes into making the wedding day a special one, planning that can be stressful and lead to lots of headaches (but only if you let it!).

Working with the right vendors will help to alleviate that stress and make the planning process much easier. As I near the big day, I will share some of the great vendors I’ve had the pleasure of working with, who have helped make planning for my wedding an exciting event! Check back for updates as we near the big day!

Ring Engstrom Jewelers: The Bling

Tungsten rods with evaporated crystals, partially oxidized with colorful tarnish. Purity 99.98 %, as well as a high pure (99.999 % = 5N) 1 cm3 tungsten cube for comparison.

This element  tungsten, which has the chemical symbol W and the atomic number 74. The name is derived from Swedish and translates as "heavy stone", in recognition of one of this metal's more obvious qualities.

Pure tungsten is silver-coloured, very hard, and has an extremely high melting point (3422 °C / 6192 °F) -- the highest for any metal and second only to carbon (3550°C / 6422°F). Tungsten is quite rare on Earth and occurs in the wild only in a number of minerals.

By now, I suppose that you are wondering where the chemical symbol, W, came from. Although this element is known as tungsten in many English and French speaking countries, a number of European countries know it as wolfram, a word derived from German, which translates roughly as "wolf's froth" or "cream" -- a reference to the large amounts of tin consumed by tungsten extraction.

Recycling, reusing and reducing are all ways in which Europeans are assisting in efforts to reduce greenhouse gas (GHG) emissions. It is a far cry from the days when we threw everything away without thought. Now we know it is the simple solutions that are making the difference. One example is lighting, which accounts for 14 % of electricity consumption in the EU. As a result, incandescent bulbs are being phased out in Europe and replaced with new energy-efficient and eco-friendly lighting technologies.

The EU has committed to cutting its GHG emissions by at least 20 % by 2020 and to improving energy efficiency also by 20 %. As part of this effort, the European Commission launched its Green Paper on 'Lighting the Future - Accelerating the deployment of innovative lighting technologies'. This in turn is raising awareness of the benefits of light-emitting diode (LED).

This Green Paper is part of the Digital Agenda under the Europe 2020 strategy for smart, sustainable and inclusive growth. It sets out the key issues to be addressed in a European strategy aimed at accelerating the deployment of high-quality solid state lighting (SSL) for general lighting. Its main objective is to help Europe achieve its key energy efficiency, industrial and innovation policy objectives.

Few tools are as invaluable to a chef as the right knife. And, to ensure that the tool keeps its cutting edge, a knife sharpener is equally important. Sharpeners come in both manual and electric models.

An electric knife sharper is better for knives used to cut bones or frozen foods, where a razor edge isn't needed. A manual sharpener will give a precise cutting edge for foods such as meats and tomatoes. Some models offer both manual and electric sharpening.

An ideal knife sharpener starts with a hard, abrasive surface - such as diamond, tungsten carbide or high-alumina ceramic - then uses steel or other ceramics for polishing. Sharpeners made of diamond or tungsten carbide tend to be more expensive; they sharpen quickly but pose a danger to some metals. Among manual models, butcher's steel and ceramic sticks are good for everyday use. For precision in a manual model, look for one made with diamond, tungsten carbide or whetstone. Stone sharpeners, safe for most knives, wear out over time.

Ferro-Tungsten

Ferro-tungsten is a master alloy for the production of tungsten-containing steels.  The raw materials for ferro-tungsten production are rich ore or ore concentrates of wolframite or scheelite.  Also artificial scheelite or soft scrap can be used.  The tungsten trioxide in these compounds can be reduced either carbothermically in electric arc furnaces or metallothermically by silicon and/or aluminum.  Also a mixed carbothermic-silicothermic production is in use.

Commercial ferro-tungsten contains between 75 and 85% W.  It has a steel grey appearance and a fine-grained structure consisting of FeW and Fe2W.  It is supplied in 80–100 mm lumps.

Melting Base

Melting Base is another master alloy in tungsten steel production. It can have various compositions according to the tungsten scrap material in use. The tungsten content varies depending on type between 10 and 38% besides iron and sometimes 5.5% Mo and also 5 to 10% Co.

Different types of scrap materials are mixed to meet the required composition. Reductive melting is done in electric arc furnaces and the melt is finally granulated by casting on a rotating disc and quenching in water (size <10 mm).
