Does Anyone Know Where I Can Get A Reliable List Of Ingredients Contained In The H1N1 Flu Vaccine?From what I have been able to confirm so far , there are multiple scary ingredients that have nothing to do with a flu vaccine. I have a tenative list of at least 30 ingredients in the vaccine that make the vaccine very unsafe for a variety of individuals and reasons. The ones I have here is only a partial list since space may be limited Aluminum Hydroxide - Aluminum can greatly increase chances of getting dementia Aluminum Phosphate ammonium sulfate - sulfate items combined with copper can destroy the important benefits of copper in our bodies - copper is needed for healthy blood just for starters Mercury thimerosol - has been previously banned from previous vaccines for the obvious dangers of mercury. -- YET it has now reappeared in the 'swine flu vaccine' phenoxyethanol - also found in antifreeze formaldehyde - are they trying to 'pickle our insides'??!! HCG - human sterilizing agent Live H5N1 avian influenza - leads to Dna 'recombination'when mixed with H1N1 Squaline --compromised Immune System - why would this be put in a flu vaccine knowing the harm it causes to immune systems? For those of you who don't consume pork products for various reasons these items are also in the vaccine - very disturbing if true. Porcine (pig) pancreatic hydrolysate of casein Pig's blood gelatin (normally from pork products) hydrolyzed gelatin (same as other gelatin) oh yeah one last item that doesn't make sense - micro chips (those are usually meant for monitoring) [ Read More ]

Arrhenius Equation?The phosphodiester bonds that form the Dna backbone are very stable. Their half-life at 25 ºC is 1.4 × 105 y (years), or knon-enzymatic = 1.56 × 10-13 s-1. Staphylococcal nuclease hydrolyzes those bonds with a rate constant of kcat = 207 s-1. By how much does staphylococcal nuclease lower Ea for this reaction? (Use the Arrhenius equation and assume that the value of 'A' does not change between reactions.) a. ) 76 kJ/mol b. ) 86 kJ/mol c. ) 96 kJ/mol d. ) 106 kJ/mol any help is appreciated! [ Read More ]
