Recently I witnessed some light rain which evaporated fairly quickly after landing on the concrete. However, I noticed it on two sections of the sidewalk which were of about the same color and exposed equally to the rain, and one looked much wetter, as if the rain wasn't evaporating as fast. Why might this happen? What hidden variables might be in effect? 69.111.191.122 ( talk) 00:08, 24 May 2008 (UTC)
Are there any studies being conducted (besides this one: http://biology.plosjournals.org/perlserv/?request=get-document&doi=10.1371%2Fjournal.pbio.0050193&ct=1#journal-pbio-0050193-box01) that are looking for the effect of bisphenol a in humans through out the lifespan? They must be looking at only bisphenol a's effect, I don't want any other chemicals in the study being studied for their effects. 68.148.164.166 ( talk) 01:16, 24 May 2008 (UTC)
I tried a couple of years ago to add the pulser pump to wikipedia. It is a simple river driven pump for 3rd world use that has no moving parts. I made one in Ireland and it is now 20 years old and still working. I have posted details on the web including video but for whatever reason, nobody in the scientific community has ever bothered to independently verify it. Its component parts are well know. (Trompes and airlift pumps). So it is a very short mental hop to realize that they actually work. But nobody has bothered verifying it. I invented the mechanical mathematician in late summer 2007 and it is now on solarcooking.org It is a tool for making parabolic dishes and moulds from clay. I invented the dripper trackers early this year and solarcooking.org put them in their recent news section. Dripper trackers are appropriate tech timer/counterweight devices for tracking solar reflectors. There are no patents involved. Is there any way to fasttrack them onto wikipedia so more people can make and use them?

Ok then, the pump has been on the internet glossary of pumps for about 5 years. Does that count for anything? Also, since people who might use the pump often use wikipedia for reference, is there any chance that you can add a proper definition of trompe to wikipedia? They were widely used in Canada, spain, france, and the USA before hydroelctricity. In mines especially and even to operate pneumatic equipment for building alpine tunnels! Gaiatechnician ( talk) 22:19, 24 May 2008 (UTC)
I dont care what you call it, You can call it a combined airlift pump and trompe if you like but why not have at very minimum a definition for trompe on wikipedia? Trompes are real things that were used for over a hundred years and which are documented in engineering reference books. Pulser pump (I do not care what you want to call it) is a combined airlift pump and trompe and has no moving parts.
( http://members.tripod.com/~nxtwave/gaiatech/airliftreferences/trompinfo.html) is trompe info supplied to me as a result of a web request. but of course wikipedia cannot use it because it comes from my webpage and not from a book that I have. It is clear that nobody is bothered to get the info themselves. I am sorry to be annoyed but rams are absolutely nothing to do with trompes. I am done being bated by people who will not do their research. Gaiatechnician ( talk) 07:20, 29 May 2008 (UTC)
Knowelege of trompes can help riverside people in poor countrys have better lives. You can either provide them with that information or hide it from them. Feel free to concede that it is not a ram and lets make progress here. Why hide useful information away from poor people? Trompe still does not have a proper definiton in wikipedia. Why? It has been 5 days. Ample time indeed Gaiatechnician ( talk) 00:01, 30 May 2008 (UTC)
What is the best way to prevent a buildup of earwax? —Preceding unsigned comment added by 79.76.238.57 ( talk) 02:56, 24 May 2008 (UTC)
Hello every one! I've created a new template on molecular and cell biology. Since, I do not have much experience and confidence in editing such sophisticated material, and also don't possess the requisite expertise in the field, I request others to go through the template and edit it in accordance. Moreover, I felt this was a very fundamental topic, which didn't have any template, so created that.
I don't know if there is a provision to notify users accessing articles related to the template that such a template has been created, and that it could be included on the pertinent pages.
Regards.

I'm confused by the article. Are they saying that bisphenol A actually occurs naturally in the environment? Chemical reactions actually happen in the environment to creat bisphenol A with or without catalysts? And if so, is this peer reviewed?
Another entirely different question:
Does industry funding have any importance once a piece is peer reviewed?
I mean, if a piece is industry funded, and the funder decides that results are not in its intrests, they can pull out funding, or if in the middle of the research, they can decide not to pay for the rat, and then even if the piece get's peer reviewed, the peers would obvious see something wrong, and the piece would have to be revised.
If the piece is industry funded, and then it gets peer reviewed, if say the rat cage was not cleaned (and this was on purposely not cleaned, so that the results would indictate not bisphenol A release (let's just say)), the peers would find it and the piece would have to be revised anyways.
So is there any way that from where a piece is funded is important to know on top of peer reviewed statusstratification?

I am buying a car soon and I have a choice between the base model and a higher model.
They are practically identical except that the base model has 15 inch wheels while the higher model has 16 inch wheels.
Does this mean that the base model will run at a higher rpm (engine speed) for the same on road velocity?
Does it mean that the base model (15 inch wheels) can accelerate faster because it can put a higher torque on the road due to its smaller wheel size? 122.107.199.2 ( talk) 10:47, 24 May 2008 (UTC)
I know there are no completed studies that are looking for the effect of bisphenol a in humans through out the lifespan, but are there and studies in the progress or are planned (besides this one: http://biology.plosjournals.org/perlserv/?request=get-document&doi=10.1371%2Fjournal.pbio.0050193&ct=1#journal-pbio-0050193-box01)?

Recently returning on a flight i just happened to notice that flying at 37,00oft there was on the wings what seemed to be water but it was moving more like a gel ???? At this altitude the temperature is as far as i am aware about between -80 to -100 . Surly the rain droplets would have frozen then fallen to earth??? Which technically would mean that the clouds would become too heavy and (fall from the skies)??? How is this???? —Preceding unsigned comment added by Mmm311068 ( talk • contribs) 11:57, 24 May 2008 (UTC)
When dosages of a particular drug are calculated such as "1mg per kg" does it matter that someone may be 60% fat and another 20% fat but weigh the same?
What is really being estimated by using the weight, is it total blood volume, metabolism etc? 78.148.84.63 ( talk) 12:44, 24 May 2008 (UTC)

If I was to throw an object at a certain speed and spin, what angular velocity would I need to spin it at such that it comes to a rest? I worked it out to 5v/2r, but I'm not sure whether my answer is right. During the calculation, I saud that F=ma, and so F(k)=Ma, μMg=Ma, a=μg. Is this right? —Preceding unsigned comment added by 76.69.241.74 ( talk) 18:04, 24 May 2008 (UTC)
You should probably also take into consideration the coefficient of friction of the ball and of the surface as well as the air resistance on your ball. Bastard Soap ( talk) 23:53, 24 May 2008 (UTC)
Well, I'm assuming air resistance to be zero. As per friction, I did take it into account, for friction is a necessary component for this to work. That's what F(k) is (force of kinetic friction). —Preceding unsigned comment added by 76.69.241.74 ( talk) 01:20, 25 May 2008 (UTC)
