Sub-bottom Profiling Equipment

3/1/2009 · Kategori: TEKNOLOJI

It is likely that you will find sub-bottom profiling equipment onboard most of the survey vessels involved in offshore investigations. Whereas the echo sounder is designed for top-layer investigations, with high-resolution and seismic equipment for deep penetration, subbottom profiling equipment covers the area in between and provides a glance into the first ten to hundreds of metres of the sea bottom. On top of this, the sub-bottom profiler is a thankful piece of equipment when it comes to enjoying onboard discussions between hydrographer and geophysicist regarding required penetration, frequency used versus data resolution, definition of the top of the seabed and features found.

 Although the principles of these analogue systems have not changed, we see further development towards refined design and specialised technology, whether in single-frequency or in chirp systems. A great number of these instruments provide data results in digital format. Data analysis and processing techniques give the opportunity to introduce bottom classification. Together with specialised geotechnical investigations, we leave the seabottom with fewer secrets every time these instruments are used out on the sea. The present survey covers types of systems, each

developed for their own specific purpose(s) and needs. Whether you need to know about the top of the seabed for accurate measurement of silt-layer thickness, or the location of boulders and

bedrock, or if you are more interested in finding shallow gas in the deeper sea-bottom layers - you will find the right tool in this product survey. Hydro international would like to thank all manufacturers who contributed to this Product Survey and responded to the questions about their products.

echnology in Multiphase Flow Metering

A range of world leading Tracerco technologies can be used to ensure your flow metering systems run at maximum efficiency.

These specialist services are used on-stream to calibrate one, two or three phase flows to confirm the accuracy of a variety of installed meters.

Areas of application include:

Technology in multiphase flow rate calibration

For many years two-phase and multi-phase flows have been common throughout the oil and gas industry. Until recently, such flows were measured by separating the flow into its constituent components in a test separator followed by conventional single phase metering techniques.

In the constant drive towards more efficient production, development has been focused away from traditional test separators towards more flexible lower cost multiphase metering. Along with these meters goes the need for periodic in-situ calibration. This has led to the development of the TRACERCO Diagnostics™ PhaseCal.

The principle of the measurement is based on the tracer dilution technique that Tracerco have been using for more than forty years. Tracerco can offer the service using either radioactive or non-radioactive tracers. In order to obtain the best quality information, each particular measurement will require subtle changes in the technique. Tracerco’s well trained staff can draw upon years of experience in this technology to ensure that the client gets the maximum amount of useful information from the tests.

Diamond

9/11/2008 · Kategori: TEKNOLOJI

For many years, the thought of finding diamonds in Canada was little more than a prospector’s dream. But that dream became a reality following the discovery, in the 1990s, of several world-class diamond-bearing deposits in Canada’s North.

Diamond exploration began in Canada as early as the 1960s, but major kimberlite discoveries were not made until the 1980s. In 1991, the first economic diamond deposit was discovered in the Lac de Gras area of the Northwest Territories. Canada became a diamond producer in October 1998 when the Ekati diamond mine opened about 300 kilometres northeast of Yellowknife. By April 1999, the mine had produced one million carats. By 2003, Canada had become the world’s third largest diamond producer on a value basis after Botswana and Russia.

Canadian Diamond Industry
Canada’s diamond industry has now become an industry worth in the range of $1.5–$2.0 billion with all indicators pointing to potential for future growth. Canadian diamond production in 2007 was about 17.0 million carats, compared to 13.2 million carats in 2006.

Diavik, Canada’s second diamond mine, began production in January 2003. During its projected 20-year life, average diamond production from this mine is expected at 8 million carats per year (Mct/y) and to peak at 11 million carats, representing about 6% of the world’s total supply. Ekati’s average production over its projected 20-year life is expected at 3-5 million carats a year, accounting for about 3% of world production by volume.

Snap Lake started production in early autumn 2007 and is expected to produce about 1.5 Mct/y in full production. It is located in the Northwest Territories about 220 kilometres northeast of Yellowknife, and is 100% owned by De Beers Canada. The deposit is unique in that the diamondiferous kimberlite is in the form of a dyke as opposed to the more common carrot-shaped pipe. The kimberlite to be mined over the project life is estimated at 18.3 Mt grading 1.46 ct/t.

The Victor project, Ontario's first diamond mine, began development in January 2006 and came into production in spring 2008. The Victor pipe has mineable reserves estimated at 27.4 Mt averaging 0.23 ct/t. While this ore grade is low, the value of the diamonds extracted, at about $440 per carat, is one of the highest in the world.At full capacity, the mine is expected to produce about 600 000 ct/y over a 12-year open-pit mine life.

Together with these mines, advanced mining projects (such as Gahcho Kué in the Northwest Territories, Foxtrot in Quebec, and Fort-à-la-Corne and Star in Saskatchewan) and the numerous advanced exploration projects across Canada ensure prosperous times to come for the economy of many Canadian regions.

Cutting and Polishing
Canada has a small diamond-manufacturing industry. In 2007, there were six diamond manufacturers operating across Canada located in Yellowknife (N.W.T.), Vancouver (British Columbia), and Matane (Quebec). These cutting and polishing factories employ about 150 workers. The largest of these facilities has an output of up to 1200 carats a month.

Employment
The Canadian diamond mining industry employs about 2650 people in mine operations and more than 1500 on-site workers through contractors in support industries such as maintenance, catering, transport, etc. Aboriginal persons generally comprise 30-40% of the work forces at the mines.

Kimberley Process for Rough Diamonds
The Kimberley Process was initiated by South Africa in May 2000 to develop an international certification scheme for rough diamonds to help prevent conflict diamonds from entering legitimate markets. Conflict diamonds originate in areas controlled by rebel groups and are often used to fund military action that targets governments.

Canada was a key player in the development of this initiative and since its inception on January 1, 2003, has been a leader in the implementation of the process to control the conflict diamond trade internationally. Canada passed legislation to control the import, export and transit of rough diamonds in Canada. By participating in the Kimberley Process, Canada is doing its part to halt the devastating impact that trade in conflict diamonds is having on peace, security and sustainable development in affected countries.

Diamonds and Sustainable Development
Canada’s diamond industry is part of a minerals and metals industry that is one of the world’s largest producers and exporters. This highly productive and technologically advanced industry provides a source of stable, high income for northern, remote, and Aboriginal communities.

Canadian mining companies are also leading the way in integrating sustainable development into their activities in Canada and abroad. The Canadian mining industry was the first in the world to develop and adopt a national environmental policy. On the international front, some of Canada’s major mining companies are involved in projects ranging from delivering health, water, and electricity services to reintegrating workers into their communities.

Natural Resources Canada advances the Government of Canada’s commitment to the sustainable development of our natural resources – contributing to their economic importance and to a strong society and communities through knowledge, innovation, technology, and international leadership.

By integrating our economic, social, and environmental goals, we can ensure our quality of life and build the Canada we want, for ourselves and for future generations.

Laptop

Laptop (notebook, dizüstü bilgisayar) alırken dikkat edilmesi gerekenler!

Sorularının yanıtları

Merhabalar. Bu konu notebook bilgisayar alan kişiler için gerçekten önemli. Peki nelere dikkat etmeliyiz.

  1. Masaüstü bilgisayar kullanırken kare ekranlara alışmışızdır. Mesela 17 inç ekranlar en yaygınıdır. Laptop firmaları ise genel olarak 15.4 inç wide ekran denilen monitör vermekteler. Şahsi fikrim laptop alırken 17 inç alın. Hem sayfalar daha güzel görünür, hem ekran yenileme sıklığı daha yükseğe çekilebilir, hem de minicik minicik yazılardan kurtulabilir, 1024×768 ekran çözünürlüğünü düzgün olarak kullanabilirsiniz… Örnek: 17.1″ WUXGA+ TFT 1920 x 1200 Yüksek Çözünürlüklü Parlak Ekran
  2. Artık bütün laptop satıcıları işletim sistemi olarak lisanslı windows vista(basic, home edition, business, ultimate) serilerinden vermekteler. Windows vista görsellik olarak aşmış boyutta. Peki görsellik ve arka planda çalışan onlarca program işlemciden yemek ramden ekran kartından yemek demek. Windows vista görünürde donanım canavarıdır. Windows vista kullanıcıları bilgisayarlarının iyi olduğu halde yavaş çalıştığına dikkat çekmekteler. Bu sorunları aşmak için kesinlikle; ekran kartı paylaşımsız notebook almaya ve mümkün ise 512mb almaya dikkat edin. Örnek: 512 MB DDR-3 nVIDIA GF8800M GTX DX10. (Direct-x 10 desteklidir) Aero performansını en üst düzeyde kullanabilirsiniz. Ayrıca işlemlerin de yavaş olduğu farkedeceksiniz. Bu durumlarla da karşılaşmamak için mümkün mertebe 2gb ve üzeri ram olan ve minimum 4gb ddr2 destekli laptop almaya gayret edin. Örnek: 4 GB DDR II 667 Mhz KINGSTON. Yani üzerinde min. 2gb ddr ram ve yarın birgün yükseltmek istediğinizde 4gb destekli olmalı. Tüm işlemlerin seri şekilde olabilmesi için günümüzün gelişmiş işlemcilerini kullanan laptopları tercih etmek gerekli. Mesela core 2 duo t7300 t7500 t7700 mobil işlemciler gibi. Örnek: Intel Centrino Duo Intel Core 2 duo işlemci T9500, Intel 965PM chipset. Sonuç olarak şimdiyi ve ileriyi düşünmeli. Yüksek ram ve yüksek çift çekirdek işlemci seçilmeli.
  3. Markaya o kadar da takılmamalı fakat teknik destek verebilecek firmalar tercih edilmeli. Birçok firmada laptopu aldığınızda cd vermiyor bunları da göz önünde bulundurun.
  4. Laptopta belki de en önemli konulardan birisi de batarya ömrüdür. Normal şartlarda 3-4 saatten az giden bataryası olan laptopları tercih etmeyin.
  5. Harddisk konusuna gelince yukarıdaki donanıma sahip bir laptopta standart olarak 5400 rpm li 250 veya 160 gb sata II disk beraberinde gelir. Normal olarak iyidir hızlı çalışır vs. Fakat ileriyi düşünmek ve daha iyi performans için mümkünse 7200 rpm ve 250 gb üzeri disk alabilirsiniz. Örnek: 200 GB 7200 RPM SATA 16MB Cache. Çünkü ek bir hdd yeri olmayabilir veya laptopunuz yarın birgün dolabilir veya yavaşlıktan şikayet edebilirsiniz.
  6. 4965 a/g/n protokolü desteki wifi kartı olmasına dikkat edin. Daha hızlı ve daha geniş kablosuz ağ için iyi bir seçim olacaktır. Örnek: Intel 4965 802.11 a/g.
  7. Üzerinde kart okuyucu olmasına, (hafıza kartı okuyucusu (SD, MMC, MS, MS, Pro, XD) firewire çıkışı olmasına ve tv ekranlarına yansıtmak isterseniz tv çıkışı olmasına dikkat edin. Örnek: 7-in-1 Card Reader.
  8. Her zaman hem internette hem de fotoğraf çekme amaçlı kullanabileceğiniz minumum 2megapiksel kamerası üzerinde entegre olmalıdır. Web kamerası için tak çıkart uğraşmamak için laptop alırken üzerinde webcamı olup olmadığı ve kaç megapiksel olduğunu öğrenin.
  9. Genel olarak bunlar. Fakat birçoğunuz diyeceksiniz ki bu özelliklere sahip bir dizüstü bilgisayar 2000 - 2.500 YTL den aşağı olmaz. Doğru fakat 1.000 ytl zaten veriyorsunuz 1000 ytl verip devamlı sıkıntı yaşayacağınıza, off bune yavaşlık diyeceğinize, paranızı biriktirin veya taksitle mutlaka bu özelliklere sahip laptop (notebook) alın derim. Pişman olmayacaksınız...
