Let q > r ≥ 1 be coprime integers.Let P c = P c ( q , r , ZIPPO H ) be an increasing sequence of primes p satisfying two conditions: (i) p ≡ r (mod q) and (ii) p starts a prime k-tuple with a given pattern H.Let π c ( x ) be the number of primes in P c not exceeding x.We heuristically derive formulas predicting the growth trend
BACKGROUND: BCR-ABL kinase domain mutations are infrequently detected in newly diagnosed chronic-phase chronic myeloid leukemia (CML) patients.Recent studies indicate the presence of pre-existing BCR-ABL mutations in a higher percentage of CML patients when CD34+ stem/progenitor cells are investigated using sensitive techniques, and these mutations
The study aimed to evaluate the phytoavailability of heavy metals (Cr, Cd, Ni and Pb) concentrations in leaves and grains, and yield of cowpea (Vigna unguiculata L) grown in soil amended with composted tannery sludge (CTS) for two consecutive years.The experiments were carried out in 2009 and 2010 in soil amended with CTS at Colour Displays 0, 5, 1
Sediment deposition in river channels from various topographic conditions has been one of the major contributors to water quality impairment through non-point sources.Soil is one of the ZIPPO key components in sediment loadings, during runoff.Yazoo River Watershed (YRW) is the largest watershed in Mississippi.Topography in the watershed has been cl
