  1. I agree with bloodhound. Depending on what you're trying to copy. I've found that if I zoom in close enough, I can copy whatever I've selected directly into word. In my experience with figures from scientific papers etc. I do not lose any quality....
  2. I use the free version. The Newest one has a small camera option (it's one of the buttons). Use the camera to select what you want, then simply past it into word and print.
  3. Well I'm no immunologist, but I'll offer what I can. First of all, you couldn't have gotten the antibodies from a hepatitis C vaccine, because there is no vaccine for hep. C. http://www.cdc.gov/ncidod/diseases/hepatitis/c/fact.htm (go down and look at "prevention". Second of all, the presence of antibodies towards hep. C usually means that you ARE infected. In fact, a diagnosis of hep. is based primarily on the presence of antibodies. If you indeed tested positive for hep. c antibodies, this is generally considered a "positive" test for the disease. http://www.cdc.gov/ncidod/diseases/hepatitis/c/faq.htm#2a (scroll down to "what blood tests are available to check for hepatitis C".) Lastly a general statement. The presences of antibodies towards a given bacteria/virus doesn't necessarily mean you are immune to the disease. Besides hep. c, another example is HIV/AIDS. Patients who have the disease display the antibodies, but since they are inected, they obviously are not immune to the disease. There are other types of hepatitis (e.g. hepatitis A and B). Maybe you are displaying antibodies to these other types?? Good luck!
  4. Don't forget a bunsen burner and a gas source so you can use proper aseptic technique....lol
  5. So by your argument, I can go around killing whomever I choose as long as it is painless, quick, and they have no prior knowledge of the attack?
  6. So, what do you think Bush would do if Iran got nukes? He's already invaded Iraq because the "thought" they had them.
  7. I have it and I'm pretty pleased. Works fine, but since I don't archive millions of emails, it doesn't seem to be any different then any other email.
  8. "I've heard" that humans store about 7 items for short term memory Miller, G. (1956): "The Magical Number Seven, Plus or Minus Two", The Psychological Review, vol. 63 pp. 81-97 [1] Good enough for you? I'm not familiar with your educational level, but if you keep going you'll eventually take an exam where 80% will not be attainable.
  9. Not sure, but IMO to change the amount of oxygen in a closed room would be very difficult. You'd have to make the room air-tight. Seems tough. If you're going to such extreme lenghts to increase your RBC's why not just "blood dope". Have your blood removed, then separate the RBC's and inject them back into yourself. Not too sure about the intracicies of this but doesn't seem to be any more difficult then engineering a room with lesser oxygen. Diet can affect RBC production as well.
  10. I agree with the short term memory statement, I've heard it before. You are correct though in that what constitues a "discreet" item is a matter of semantics and opinion. Obviously remember 5-6 random numbers is different then remembering 5-6 pages of a book. Try two digit numbers. Right down 10 of them then see how many you can recall. As far as "will" is concerned, I think you have to more clearly deinfe that too. You remember your teachers name because it has some significance. You're more apt to remember things that are "important" or things that interest you rather then random things. In this sense, you do kind of have to "will" yourself to remember. Your grades are interesting. I think theres a difference between grasping the concept of something rather than memorizing it. You may do well in school because you can remeber the basic stuff. For instance, I remember core elements from my freshman chemistry class but certainly nothing intricate. While I may have aced that class it's likely I would do poorly on a simple exam right now. Try learning some very advanced theories/ideas/concepts from a very advanced level class that you have no experience in and the 4 out of 10 thing may hold true. Not so sure about the mind "filling" up. Seems there would have to be some type of limit.
  11. First I think you have to convert the stock solution of "units" into weight. Right now it seems to me that your attempting to convert two completely different things. Once you can convert the stock soultion to weight, it is quite easy, use the old equation: (C1)(V1)=(C2)(V2) (Concentration of the first solution)(Volume of first solution)=(concentration of second solution)(volume of second solution). just remember V2 is the final volume. Now you already know what C2 is: (2mg/ml). Decide how much of that you need, which would be V2. Once you determine the conc. of the stock (C1), you'll have one variable left. solve for x. (in this case V1).
  12. Just that the 5-HT1 receptor can be further classified into subtypes, which are the 5-HT1A, 5-HT1B, and 5-HT1D (there may be a few more). These are your typical 7 transmembrane spanning G-protein coupled receptors. I'm familiar with the 5-Ht1A subtype. The 5-HT1A receptor is classically coupled to an inhibition of adenylyl cycle and a decrease in cAMP. It's the serotonergic autoreceptor and is usually activated in response to high levels of 5-HT. I don't think the receptor's crytal structure has been determined yet, though I could be wrong. Thus, and 7 transmembrane spanning g-protein coupled receptor will look similar to it. I'll try and attach an image.
  13. I agree with lucid. There's an energy transfer SOMEWHERE. This would be easier to observe in a smaller "system". Put the pipe filled with water in a freezer. It's easy to see that the freezer had to input energy to cool the water. Same principle, but on a larger scale.
  14. Well, if you had read my second post you would see the response to my comment about the "only 6 figures" statement. While this is certainly an adequate amount of money a person usually only receives this at the end of a fairly successful science career. An average person receives a Ph.D in about 5 years, followed by another 3-4 years of a post doc. This is about 9 years of post-graduate work making less then 30K. Then you'll hit assistant professor and start around 40-50 and stay there for around 4-5 years. Then you'll hit associate professor where you'll start to make decent money at about 60-70. So I'm sure you can do the math. It'll be around 13-14 years AFTER your b.s. at which point you'll prob. be making around 60-70K. A professor can finish his/her career at associate or assistant professor and never make more money than this. Add on about 8 years IF you make full professor and get tenure, at which point you'll only be thinking about breaking 6 figures (80-90K). Decide the Ph.D route isn't for you? a master's or B.S. will top out around 50-60 max. Of course there are exceptions, but this is my opinion on what is considered an "average" science career. Compare this to a someone who is an engineer who starts around 60-70K directly out of college. You'll see it's not about the money. You are correct in the fact that many scientists do what they do for the love of it. Regardless of the money, become a graduate student and see if you complain. Grad students are worked to the bone, and taken for granted by professors. You have to be "above avergage" to be accepted to a doctoral program. You're reward for doing well and being top of the class as an undergraduate? working 60+ hours a week for around 19K for 5 years or so. This works out to around $6.08 per hour. I believe McDonald's pays more then that. There are few people who don't mind the work and low pay, survey your school's grad students and see what they think. All the while everyone will say "you should do it for the love". But the title of the thread was why the U.S. was losing ground in science education. The answer is that few have the drive or willingness to work under these conditions.
  15. Does an open reading frame include non-coding regions of DNA as well?
  16. lol, depends on your definition of "small".... I like rats and other rodents myself
  17. Might be a bit confused but I'll offer what I can. Isn't lacZ used as a marker? That is, if the sequence of lac Z is "connected" to your gene sequence, the bacteria will first make your gene of interest, and then read through to make lacZ? if this is the case, everytime you insert lacZ into a gene, you'll get your gene, as well as lacZ. Thus, if you got blue colonies, it would indicate your bacteria is translating the gene into which you inserted lacZ, but it wouldn't offer any insight into the function of the gene. Only that it's being expressed. Could be completely wrong with this though
  18. yeah, see what the standards are for getting in, then calculate your chances.
  19. Basically all you do is go to: start->settings->control panel->administrative tools->services Then you screw around with those settings. There's a description of each so you can get an idea of what you're doing (if all else fails you can just switch it back on). As I said before all the "tips" worked for me. I'm just curious to hear other's opinions. (Those whom obviously have more computer knowledge then I).
  20. it was just a suggestion, really, it makes no difference to me whether or not you want to check the site out. They're not outrageous tweaks, just changing some settings in windows. The site is well known and I've seen it referenced before, whether that adds to his "credibility" is up to you. As you said "all windows components can be accessed and switched off through windows itself". All this guy did was spend some time reading, and published a huge list of things you could safely turn off; after I switched settings, I now run about 14 processes after a re-boot. Helped my performace. Just offering advice.
  21. I'm at work right now so I don't know how much it will help. But there is a guy named "blackviper" who runs a website filled with tweaks to speed up your comp. (I'd post the site but I don't want to spam, just google the nickname). If you go to his site and look at the "windows service configurations" on the left hand side, he has a guide which allows you to turn off almost every non-essential feature of windows. IMO turning off the extra's speeds things up immensly. But like I said, I'm at work and I don't have the tweaks running on this comp. WHen I get home I'll let you know if it helps.
  22. Yeah, I think cnn said it was 240 million. Awesome, 240 million, gone. Your tax dollars at work. Wish this occurred before the "do we spend enough on space exploration" thread happened. In all honesty, this isn't a sarcastic comment but I've been thinking: Is there any other area in science where you can spend 240 million on a single project and then simple go: "Oops" ?
  23. I enjoy your rational debate and eloquent use of 5th grade language. It makes you sound authoritative. First of all, not all drugs are bad, take for instance LSD, there are no conclusive data indicating adverse effects due to it's use. It doesn't cause violence or aggression, thus, eliminating it's harmfulness to others. Please provide me a reference where where drugs are able to "alter your genetic code", such that it is passed on to offspring. I'd love to see that reference as well. And please, don't give me any http://www.drugsarebad.com references either. I'd like a refereed journal article (if you know what that is). I would bet that your chances of an adverse effect resulting from STD's passed on during promiscuous sex are far greater then those caused by having a beer. Your argument of "I only screw guys that look clean" illustrates your level of intelligence. The basic point is that: "Who are you to judge?". Just because a society deems drugs illegal does that necessarily make them bad? (the same is true for many other behaviors). Are you aware of the scientific gains that are made by studying particular drugs of abuse? The obvious answer is "no". You blindly follow the doctrine of what your parents and authoritative figures tell you. You cannot think for yourself to analyze a situation, or even acknowledge a viewpoint other then your own. Welcome to the flock sheep.
