Agrobacteria are used in genetic modification of plants. It is used as a vector to transfer plasmids into the plant. Is this what you mean? I think Agrobacterium usually causes tumours in the plant but the tumour causing genes are deactivated or removed before they are used as a gene vector in genetic modification (just like how HIV is an often used vector). As for what advantages the plant gains - that would depend on the genes transferred. Fungal resistance would be a common advantage chosen. Hope that is what you meant...

Hi everyone, I joined recently and I'd like to share some things I've written with you. I think they might be of interest to some people. This is the investigation I did for my final A level year. I was comparing the Kutta-Joukowski model of lift for thin aerofoils to experimental results. They fitted well (with 70% accuracy) but I had a few problems doing this investigation. Firstly in interpreting the Kutta-Joukowski model itself. The literature I read (and MATLAB model I used to design the aerofoils) took different mathematical approaches so it was difficult to piece together exactly how the model was meant to work. In the end I think I ended up creating an expression for pressure rather than lift; but this was the best I could do - it seemed close enough to the experimental results. (which is a terrible way to work but I guess that shows you shouldn't put a deadline on science!) So if anybody has any advice on the Kutta-Joukowski model I'd love to hear it. (but please don't send me any public domain resources. I guarantee you that I've read it. Several times.) Secondly I had a bit of a problem with my statistical analysis. With my lack of experience, I wasn't quite sure which method I should use to analyse my data. In the end I think I came up with quite an inventive and accurate method. I plotted a line in which (expected results) = (observed results) and found the coefficient of determination of the line with respect to the actual data points. This gave me a numerical indication of how close the expected results equalled the observed results: 70%. I once saw a flow chart on a poster which told you which statistical analysis you should use depending on the type of data you have. I've been looking for something like that since. Would somebody be able to point me in the direction of something similar? Here's the paper (any criticism or advice is welcome): JAFexperiment.pdf Also, here's the thread for my more recent Quantum Entanglement report: http://www.sciencefo...m-entanglement/ And here's the thread for my introduction to Carbon Nanotubes: http://www.sciencefo...rbon-nanotubes/

Hi everyone, I joined recently and I'd like to share some things I've written with you. I think they might be of interest to some people. This is a presentation on carbon nanotubes that I made three years ago. They are fascinating things. The presentation should suffice to give a good overview of nanotubes. If you want to make any corrections, comments, or additions just tell me and I'll make some changes. Three years ago I asked to visit the Cambridge nanotube lab but the professor was away at conferences - I might ask again sometime soon The best way to view the presentation is to start the slide show from the beginning and click through it (rather than reading it in the editing mode because some of the pictures overlap and there are videos). Here it is: CARBON NANOTUBES2X.pptx Also, here's the thread for my more recent Quantum Entanglement report: http://www.sciencefo...m-entanglement/ And here's the thread for my more recent investigation into Joukowski Aerofoils: http://www.sciencefo...-investigation/

Hi everyone, I joined recently and I'd like to share some things I've written with you. I think they might be of interest to some people. This one is my final year A level report on quantum entanglement. It gives an explanation of the mathematical principles behind quantum mechanics and then goes on to talk about electron spin and the EPR experiment. It's quite possible I've made a mistake in some parts so do not hesitate to call me out on it so I can make corrections (stylistic criticism is also welcome). I certainly found the philosophical ramifications of the EPR experiment quite difficult to grasp (and hence write about). If somebody could illuminate this in a simple manner it would be much appreciated. The two most useful resources for this were undoubtedly Leonard Susskind's excellent Quantum Entanglement lecture series (which is available on iTunesU) and Paul Dirac's Principles of Quantum Mechanics (beautifully written by a true genius, highly recommended). Anyway, here's the report: QuantumEntanglement.pdf And here's the thread for the investigation I did into Joukowski Aerofoils: http://www.scienceforums.net/topic/59743-joukowski-aerofoil-investigation/ And the thread for my introduction to Carbon Nanotubes: http://www.scienceforums.net/topic/59742-an-introduction-to-carbon-nanotubes/ (Oh and I ended up getting an A* in my A level and I'll be off to study physics at university in two weeks )

Mmm... Can you imagine Briancoxium? I hope I can make my great discovery soon so that I'll be eligible for the naming Who decides the names? Is it the IUPAC?

Hey, I'm Fogo. I enjoy all areas of learning but I'm particularly interested in physics, mathematics,and philosophy. I recently had a dream that I met Richard Feynman - I awoke, disappointed that I had not met him and doubly disappointed that I never will But there's no need to be depressed! There are many great minds and many fine ideas to come... See you all soon! EDIT: Oh! I just noticed the forum ranks - they're brilliant!
