Water Quality Monitoring in North River and Little River in Nottingham, NH
The Town of Nottingham Conservation Commission (NCC) in New Hampshire purchased water testing equipment for monitoring the North and Little Rivers as part of the New Hampshire Volunteer River Assessment Program (VRAP). The equipment enabled NCC and Lamprey River Watershed Association (LRWA) volunteer water samplers to efficiently monitor water quality on the two rivers twice a month from May 2007 to June 2008
Refined Goldbach conjectures with primes in progressions
We formulate some refinements of Goldbach's conjectures based on heuristic
arguments and numerical data. For instance, any even number greater than 4 is
conjectured to be a sum of two primes with one prime being 3 mod 4. In general,
for fixed and coprime to , any positive even outside of a finite exceptional set is expected to be a sum of two
primes and with , . We make
conjectures about the growth of these exceptional sets.Comment: 10 page
