What was the Standard-gauge railway's initial gauge?
- The initial gauge of was set to accommodate the existing gauge of hundreds of horse-drawn chaldron wagons that were already in use on the wagonways in the mines.
- How long did this standard last?
- The railway used this gauge for 15 years before a change was made to the 4 ft in gauge.
- Are there any other interesting aspects about this article?
- The historic Mount Washington Cog Railway, the world's first mountain-climbing rack railway, is still in operation in the 21st century, and has used the earlier 4 ft 8 in gauge since its inauguration in 1868. George Stephenson used the 4 ft in gauge (including a belated extra in (12.7 mm) of free movement to reduce binding on curves) for the Liverpool and Manchester Railway, authorised in 1826 and opened 30 September 1830.
- Did any other routes use that standard?
- The success of this project led to Stephenson and his son Robert being employed to engineer several other larger railway projects.
- Did any of his routes remain private?
- 

Thus the 4 ft gauge became widespread and dominant in Britain.

What is the Mekong Basin Disease Surveillance?
- Mekong Basin Disease Surveillance The Mekong Basin Disease Surveillance (MBDS) consortium is a self-organised and sub-regional co-operation spearheaded by health ministries from member countries to collaborate on infectious disease surveillance and control.
- What countries are members?
- The co-operation focuses on cross-border co-operation at selected sites and has matured through several phases of work.
- What is the program's ranking in the world?
- PRO/MBDS is a component of the outbreak reporting system ProMED-mail.
- When was the program started?
- The Ministries of Health of Cambodia, China, Laos, Myanmar, Thailand and Vietnam signed the Memorandum of Understanding (MOU) in 2001 in Kunming, China, with the Regional Coordinating office agreed to be located in the Ministry of Public Health (MOPH), Thailand. Dr.
- Who is the director of the program?
- 

Moe Ko Oo MBDS Coordinator, c /o Ministry of Public Health MBDS has applied epidemiology and GIS, initiated tabletop exercises (TTXs) on Pandemic Preparedness in country and regional levels in 2006 and 2007.

What are the different applications of Scanning transmission electron microscopy?
- However, at the time the results were inferior to those of transmission electron microscopy, and von Ardenne only spent two years working on the problem.
- Are there any other interesting aspects about this article?
- The microscope was destroyed in an air raid in 1944, and von Ardenne did not return to his work after World War II.
- Did anyone try to rebuild it?
- The technique was not developed further until the 1970s, when Albert Crewe at the University of Chicago developed the field emission gun and added a high quality objective lens to create a modern STEM.
- What did he do after that?
- He demonstrated the ability to image atoms using an annular dark field detector.
- Did he image any other things?
- Crewe and coworkers at the University of Chicago developed the cold field emission electron source and built a STEM able to visualize single heavy atoms on thin carbon substrates.
- What did this lead to?
- 



assistant: By the late 1980s and early 1990s, improvements in STEM technology allowed for samples to be imaged with better than 2 Å resolution, meaning that atomic structure could be imaged in some materials.
