I am looking for competitive Liquid Radioactive Waste Treatment Facilities Suppliers. I know that the French are leaders, but are there any other companies from other countries that have commercial facilities for Liquid Waste Treatment?

I will start working on a totally new field for me. Nuclear. It's seismic related and that's where I step in. I am at ease with structural design and seismology but nuclear is new. Can anyone indicate me some good and trustworth sources of information: govern, industrial, etc. to start on...

AASHO T147-49. I am looking for this standard. It is unavaillable in my country. Does anyone know how and where I can obtain it from?

Hello everyone, I have been having some difficulty in finding the text of the standard: AASHO T147-49. Does anyone know where I can get it from or download it?

Maybe I wasn't very explicit. My problem is findind the regression line. I mean, a good regression line, because the ones that i tried weren't good aproximations. Maybe it's not possible to be accurate with standard Excel functions.

I recommend everyone a very good book that i bought: "A guide to Microsoft Excell for Scientists and Engineers" Bernard V Liengme. It is a real manual. Works on math issues rather than the basic stuff. You realise of some limitations of spread-sheets, but then again its a good sign, it...

I started to develop macros in EXCELL spreedsheets for particular aplications and soon realized that they are tricky. I learned that you must execute macros locating (the cursor) in the sheet it is supposed to start, otherwise you woul watch it perform the operation over the wrong selection, for...

I have 4 points in a graph and i can find a tendencie line but when i try to find a 4th degree regression line with the parameters m1,m2,m3,m4 and b it turns out to be a very bad aproximation. I am trying to find the right equation in order to find its maximum. Does anyone know what is the...

I am traveling to Canada for a 6-month work experience. Can anyone inform me about the classification of structural materials, their application and the main structural characteristics (yield stress of steel, compression stress resistance of concrete, and module of elasticity of both? Thank you...

Unlike regular and normal structures, especial structures demand a lot more from you, for not everything comes in codes and standards. Some things come with experience and are not scientifically tested. You have to make some adaptations and create your own models. It is not always possible to...

I think I can help you with some theoretical explanation: Torsion in beams is indeed a special situation. It does not represent a regular problem, for Polar inertia of cross sections of beams is very low- you can compare their values to the inertia of a same cross section about bending axes...

Does any know where I can find Canadian Regulations for structures (concrete, steel and others) or at least their designations and jurisdiction?

Thank you very much Imagineer. In case you need any information from the European Community go ahead.

I am a structural engineer from Portugal. I am looking for information on: 1. US and Canada most used units system besides the International System (S.I.); 2. Canadian regulations for construction: reinforced concrete and steel structures. Can someone indicate me where I can download a copy of...
