Can anyone let me know Chemical Composition for Corter Steel?
I Want to Fix this Oscilloscope but….
Hello
I have a somewhat old oscilloscope I bought for a 1$ and paid 20$ shipping on and I see it has a tube missing . In the picture you can see it is 6AX5 as labeled and included in the manual for the scope (here is a link to that Manual). I should first ask if any one can tell what tha
Multiphase Pump Application
How much sense will it make to specify a multiphase pump for crude oil with GOR of 20
and a paltry flow rate of 4000 Bbl/day?

Determining the Diameter of the Winding of IM
i would like to modify an induction motor from three phase to multiphase. that means i have to change to windings configuration since the amount of the current flows will also change too. Does anybody knows the relations between the amount of the current flows and the diameter of the windings? or
CO2 Emission
How to stipulate and calculate the CO2 emission from flaring system? Is there any engineering practice and simple formula for reference?
Thanks

Changing my world
After writing last week about a pretty major 5 year anniversary – the discovery on Dec 28th 2004 of what is now called Haumea – it seems funny to be writing once again about a 5 year anniversary. But that’s just the way that reality worked. Eight days after discovering Haumea, and just a few days into the new year of 2005, I was back in my office again. I wanted to be studying Haumea – or Santa, as we called it then – since I was certain that it had to be bigger than Pluto, but, sadly for me, we still didn’t have any new data on it. We only had those first three pictures and there was nothing new to learn. We were scheduled to get more data soon, but not soon enough for sooth my anxiousness. My fingernails were nubs.
Trying to keep myself from going crazy, I spent my time searching through old images of the sky. These images were the ones I had been taking over the past few years to search for objects in the Kuiper belt, the same images in which we had already found Santa and also Sedna and Quaoar. I was re-looking through all of my old images to see if I had missed anything the first time around. I was particularly interested in things that were far away and thus moving very slowly. Since I was finding things by the fact that they moved, very slowly moving things were particularly hard to find. Often, things that I thought were slowly moving were actually just stationary stars that had shimmered a bit in one direction or another while I took my pictures, fooling me into thinking that they were really moving. Because it was so hard to find this slowly moving ones I had originally not tried at all. When I searched through all of my images the first time, no one had ever found anything further away than about 60 AU (about twice the distance of Neptune), so I thought, to be safe, I would set a limit of 90 AU. Beyond that I would give up and leave the discoveries for another astronomer.
But in November 2003 I found Sedna, by the skin of my teeth, at 89 AU. It was so unexpected and so far away that for weeks I didn’t even believe it was real. We finally got confirming images on Thanksgiving Day. Sedna turned out to be, I still believe, the most important scientific discovery that came out of all of my searching of the outer solar system. Sure, finding things bigger than Pluto is cool, but it doesn’t fundamentally change the science of what is out there. Sedna in so many ways does. Nothing was supposed to be out there where Sedna was. And Sedna was even more strange. Rather than being far away but spending much of its time closer like, say, a comet would, it was far away and spent almost all of its time even further away. To this day Sedna’s origin remains a mystery. And the way to solve the mystery of Sedna is to find more like it. And the way to find more like it is to find things even further away. And, in 2004, the only way to find things further away was to slowly, tediously, go back through every single one of the images that I had already laboriously looked at and look once again to see if there might be something else there, moving so slowly that I missed it the first time around.
I had spent 100s of hours doing this re-searching. It was mind numbing. But I knew that it was my only chance of finding something like Sedna, something else strange in the outer part of the solar system.
So, on January 5th, 2005, really wishing I could be studying Haumea, I instead went about the tedious business of looking through old images once again. I finished all of the images from October 20st, 2003 and loaded up the images for the next night. I spent the usual tedious 20 or 30 minutes going through the first half of the images until I came to one that made me stop.
On my screen was something moving – just barely – that was almost the brightest thing I had ever seen. In fact, only one moving thing had been brighter, and that had been Haumea itself, 8 days earlier. It was moving so slowly that I could tell that it was perhaps twice as far away as Haumea. And it was so bright that it had to be big. Very very big. I did a quick calculation on a scrap of paper sitting on my desk and realized that this thing was, without a doubt, bigger than Pluto.
I make groundbreaking discoveries all the time. Really. Any good scientist does. And by now I know exactly how to react: assume I did something wrong and figure out what it was. Usually it only takes me a few minutes to realize I am totally, thoroughly mistaken. Sometimes I can hang on to that delusion of a big discovery for 10 or even 15 minutes. On occasion, I can even go for a few days before I realize what my dumb error was.
This was 5 years ago. That was Eris. Eris is, beyond a doubt, real. That morning, while trying to kill time, waiting for the day when we might finally get some interesting data about Haumea, I had made the discovery that Discovery News called one of the top 10 science discoveries of the decade.
On the evening of January 5th 2005, five years earlier than the evening that it currently is, I had secrets that only a few people knew. I had just found something bigger than Pluto. Diane was 3 months pregnant. The world was never going to be the same. I couldn’t wait.
Japan’s Plan for Emissions Reductions
Kambayashi/AP - Japanese Prime Minister Yukio Hatoyama speaks during his first press conference of the year.
Japan released its New Policy Agenda of Japan on Climate Change in English in mid-December. (Download the agenda here). According to their document, it both verified their proposed reductions of 25% and proposed new substantive reductions.
“. . . . Prime Minister Hatoyama stated that the new mid-term target to reduce emissions by 25% compared to 1990 levels was hinged on establishing “a fair and effective international framework in which all major economies participate,” but made no clarification whatsoever of his standards for “fairness.” In fact, perhaps equitability criteria have not yet been defined even within the government. . . .
“The new mid-term target, or “30% reductions below 2005 levels” represents the most stringent of the four options discussed in the Mid-Term Target Review Committee under the former administration. It had once been dismissed because it would have too large an impact on the economy and the policy tools and scale that it called for were unrealistic.”
The U.S. is only proposing a 17% reduction in emissions based on 2005 levels, which is about a 4% reduction based on 1990 levels. It must be tough for the U.S. government to be “bettered” in this way by countries as small but ambitious as Japan. Can’t the U.S. do more? We need to at least try. More ideas from the Japanese agenda:
Actually the number of 17% of the U.S. is with respect to 2005.
Vision for a Developed-Developing Country Cooperation Model: For International Contribution by Industry to Climate change Solutions
(1) Industry should also consider ways to “bridge” developed and developing countries. Contributions should be centered on substantively reducing GHG emissions through energy and environmental technology transfer and international intersectoral cooperation and agreement and supplying products that will contribute to creating a global low-carbon consumption society in terms of LCA (life cycle assessment).
(2) Japan, the US and China should launch a model project of developed-developing country cooperation based on public-private partnership in areas including energy conservation, renewable energies and nuclear energy. Reductions generated in the project should be trilaterally accredited among the three countries as offset credits that could be used for the purpose of staying in compliance with domestic schemes.
(3) Furthermore, industry could also look into setting up a new organization provisionally called the Institution for Engineering
Solutions for Climate change, which would be based on public-private partnership to promote the projects described above, to implement the Voluntary Action Plan in wider international dimensions and to collect benchmarking data.
They make a good point below about individuals versus countries (which is also an idea I like since Copenhagen collapsed into political fighting Individuals and their cities and states will make up a huge part of fighting climate change, but how much is possible is yet unknown).
However, in order to employ equalized emissions per capita as an equitability standard, fundamental rules under the Kyoto Protocol [...]
Keep Correcting the Deniers Because Exxon is Still Paying Them
GOP Protest Builds Against EPA Regulating Greenhouse Gases
A storm of Republican protest is erupting over the Environmental Protection Agency’s finding that greenhouse gases pose a public danger, with the latest wave coming from a state among those most at risk from the effects of climate change.
Republicans are stepping up their efforts to stop climate change legislation. They are also continuing their campaigns of propaganda to create confusion in the public’s mind about global warming.
We really have to keep pushing back at the deniers and climate change skeptics before they do any more harm to public opinion, because they are pulling out all the stops. Their new campaign is “CO2 is Green”. This is from Media Matters:
A new group named “CO2 is Green” (really) is contending that “CO2 is not a pollutant. CO2 makes Earth green because it supports all plant life. It is Earth’s greatest airborne fertilizer.” (Astoundingly inaccurate!)
The Washington Post wrote:
The man behind the latest entry to the climate legislation wars is H. Leighton Steward, a veteran oil industry executive, co-author of the “Sugar Busters!” dieting books, and winner of an Environmental Protection Agency award for a report on damage being done to Mississippi wetlands. Now retired, he says he wants to “get the message out there” that carbon dioxide, which the Supreme Court has ruled a pollutant and which most scientists regard as a dangerous greenhouse gas, “is a net benefit for the planet.”
Steward has joined forces with Corbin J. Robertson Jr., chief executive of and leading shareholder in Natural Resource Partners, a Houston-based owner of coal resources that lets other companies mine in return for royalties. Its revenues were $291 million in 2008.
Not only have Steward and Robertson founded “CO2 is Green” to take misinformation to the airwaves, they’ve also launched “Plants Need CO2″ to educate Americans about the joys of carbon pollution.
They have formed two groups — CO2 Is Green designated for advocacy and Plants Need CO2 for education — with about $1 million. Plants Need CO2 has applied for 501(c)(3) tax status, so that contributions would qualify as charitable donations, said Natural Resource Partners general counsel Wyatt L. Hogan, who also serves on the group’s board.
This has to be fought against. Some kind of climate legislation has to get passed this year, preferably a tax and dividend bill. (See the Larson bill in the House. America’s Energy Security Trust Fund Act of 2009). The cap and trade bill isn’t good enough because it won’t right climate change aggressively enough, but we can work on making that stronger.
In the meantime, working against us will be this denier cult, which is really driven by money and greed. (Join the CO2 is Green Facebook group here and have some fun setting them straight.) Wherever people see climate deniers online, my recommendation is to respond to them with as many facts as you can.* They are using new tactics, straw man arguments, red herrings, blatant lies, you name it, [...]
It’s beginning to look at lot like Cusco
So wersquove been travelling in South America just over 2 weeks and we are now more than a week behind on our blog. I blame a couple of things but the fact that we have been in remote areas and places without wifi are the main reasons for this difficulty hard to find a good internet connection in the middle of the Inca Trail. So to try to sum up our activities we are starting with our Dec
Arrival at Gainesville
At the moment Gainesville happens to be in one of the coldest recorded cold fronts. At the moment it averages around 5C here so it is freezing espically since I did not pack a single warm winter jacket Its really different to australia here the main thing is driving on the other side of the road which has really messed me up as I always look the wrong way the other main thing is how much food
