I would like to make a 44 inch by 36 inch Cyanotype print. I have purchased the necessary chemicals: Ferric ammonium citrate and Potassium ferricyanide.

Is anyone experienced enough with Cyanotype process to inform me of how to properly mix the chemicals to create a rich blue print? (how much of each chemical should be added to how much water etc.) Keep in mind the final print dimension is 44" x 36".

More importantly, how do you get them to START with the healthy eating habits and quit the bad ones?

How do you tell your child they cannot have that second cookie, or that cone of ice cream and avoid their disappointment?

What were some things you did with your children to get them to PREFER eating healthier?

The percent abundance of 40K (t ½ = 1.27 x 109 years) in naturally occurring potassium is 1.18 x 10-2. Calculate the total 40K activity, in units of disintegrations per hour, in a person with a mass of 77.3 kg of which 0.339% is potassium. Use 39.96 amu as the atomic mass of 40K.
Yes it is hard and I’m not sure how to do it.

If it helps any, activity = hn, where n is degenerations and h is 0.693/the half life (t1/2)

fractional abundance = # mol of radioactive nuclei/ # mol of sample
oops h is decay constant.

I’m having a hard time understanding why, its a practice question for a physiology test how would the kidney tie into the relationship of marathon runner and potassium stores?

What is His Plan for them?

My husbands blood pressure is suddenly (in the past 2 hours) high and his heart rate has more than doubled his normal. It’s about 120 bpm Instead of his normal 55bpm. And he is having shortness of breath. He boss wont let him leave, but I think it may be something that may need to be checked out. What could cause this?
