Measuring large radii
Article Abstract:
Davis Stone of Syracuse, NY has developed an equation that can be used with basic measuring tools to determine the values of large concave or convex radii. The equation can be used when measurement of a large radius becomes difficult, when the dimension being measured exceeds the capacity of measuring equipment, or if the center of the radius becomes inaccessible. The technique can be used over a wide range of radius sizes, and on surfaces with allowable tolerances, such as those found on large radius parts.

A 75-Year-Old Man With Congestive Heart Failure
Article Abstract:
Treating patients with congestive heart failure can be a challenge. About 1% of those aged 50 to 59 have congestive heart failure and 10% of those older than 80 years have it. It can be difficult to diagnose because other diseases can cause similar symptoms. Only about half of older patients with severe heart failure will survive for one year from their diagnosis. ACE inhibitors, diuretics, beta blockers, digoxin, and heart transplantation are the primary treatments.

Principles of sustainability
Article Abstract:
Five principles are defined: appropriate use of technology; ecological preservation; aesthetic harmony; social justice; and democracy. Automobile dependency is not sustainable, and it is unjust for planning to perpetuate auto dependency when 40% of poor Americans cannot afford a car.
