  1. Therefore GPs are scientists even if they do not engage in research. http://medicalsciences.med.unsw.edu.au/somsweb.nsf School of medical sciences - faculty of medicine When I was working at the austin hospital I was not engaged in research, merely routine laboratory work, but I was never the less a grade 1 medical scientist. Exclusive engagement in scientific research does not seem to be a requirement for the title of 'scientist'. But then again the art of diagnosis is very much like research. The GP gather's initial evidence from the patient and formulates a hypothes
  2. Westerners can't fight off malaria well at all.
  3. I am pretty certain that iron does not form a complex with ammonia.
  4. What about when the human rights of people alive today conflict with the human rights of future genertions? E.G. Around procreation and over population and exhaustion of natural resources.
  5. I thought he meant that the coordination complex itself was insoluble. Interesting, pretty much the same colour as the copper coordination complex. What else apart from Ni, Ag and Cu forms a complex with ammonia? It always intrigued me as to why say iron does not form a complex with ammonia. Why is that?
  6. 0.05M is simply 1/20 the concentration of 1M So you would take 5ml of your stock and mix it with 95ml of water.....do that x times to end up with the volume you require. If you need the NaCl then work out the total weight required for the total volume of your working solution and just dissolve it in the working solution.
  7. If africa is not over populated then why does the continent suffer from perpetual famines, war, genocide and political instability etc? Racist slurs are not a substitute for reasoned arguments. And you are wrong anyway. To coin a phrase my brother once jokingly used "I am not racist, I just hate everyone" If westerners were advocating the use of DDT in the west to control malaria and prevent deaths I would be saying EXACTLY the same thing.......that their interests in not dieing from malaria do not trump the interests of future generations in not having their environment and
  8. Because spending their money on disseminating DDT in Africa will ultimately effect me, my children and our local environment and I f'ing well OBJECT. Preventing malarial deaths in an over populated Africa does not justify the long term adverse impacts of DDT across the globe. The interests of individuals in Africa do not trump the interests of future generations across the globe. And more particularly the interest of soft westners who have an unrealistic abhorance of death, and who our out to make a name for themselves in charitable circles, do not trump the interests of future ge
  9. Perhaps they do make a cursory attempt to explain to africans about the risk of DDT. But one may as well go down to the local Ultratune and try to explain to the teenage apprentice motor mechanic about the chemistry and health risks of DDT. It is an exercise in fultility unless you are do so to some one with at least a basic science education. So until they can make africans understand DDT at our/their education level they have no right to thrust it upon them. I have no interest or inclination to donate money to current aid efforts in africa or any where else in the wo
  10. The best I can do on proof of poor african awareness of DDT is to provide evidence of the poor general education standard in africa: There is plenty of material on the web detailing this. If education standards are low then it is reasonable to assume that few are savy about DDT. And as for the rest of you post swansont...... You are only comparing death rates of malaria and DDT exposure. What about the chronic health effects of DDT exposure? There is ample anecdotal evidence to support that and enough for western countries to pahse out its use. Why then do westerners seek
  11. Perhaps it was a combination of environmental wisdom similar to Aboriginal culture, strong resource base, high infant mortaility, short life span and sporadic clan warfare that kept their numbers in check and the civilisation stable on average for so long. I seem to also remember a mention in Tim Flannery's book about the equivalent of aboriginal story places where hunting etc was prohibitted for game conservation purposes and the disruption of this system by christian missionaries.........but was that the central highlands civilisation or was it more the coastal tribes......I am not sure now.
  12. Sorry swansont but I cannot provide you with proof that average africans have no idea exactly what DDT is. But most would agree that it is a reasonable assumption given the general education standards in africa. I actually tried a bit of googling on the subject but all I came up with is dip $%#& westerners telling africans and western opponents that they ought to accept the use of DDT to eliminate malaria. But nothing about them taking the trouble to educate africans about the health risks of and contraversy surrounding DDT. A bit about the Stockholm conevention trying phase out the us
  13. Is nickel diamine what ever insoluble is it? We did the copper ammonia thing in high school and I mucked around with it at home but it never occured to try it with nickel salts or anything else.....not that such salts are easily available at the super market or the garden centre. Chemistry is fun - it was my all time favourite subject at high school. I learned quickly about house hold use of assorted chemicals because I was always on the look out for a cheap source of them to experiment with.
  14. Oops.......reflex action.....will rephrase the post as a non-Cuthber reply
  15. Solubility is ability to dissolve in a solvent. There is no difference between a coordination complex involving water molecules (which many or most salts form when they dissolve in water) and a coordinaion complex involving both ammonia and water molecules. So I have not the faintest idea what you mean by this statement iodine: And Cuthber specifically refered to solubility of Ag2S as determining whether or not ammonia could break the chemical bonds. And I have never once indicated that I believed that the chemical species in ammonia solution would be (Ag(NH3)2)2S
