Influence of acidic atmospheric deposition on soil solution composition in the Daniel Boone National Forest, Kentucky, USA
Soil solution chemistry provides insight into element cycling, nutrient uptake and availability, mineral transformation, and pollution transport processes within the subsurface environment. Therefore, chemical analysis of the extractable soil water fraction has been utilized in several studies to assess the condition of ecological resources and to identify stresses, and levels thereof, which ma...
متن کاملBooNE Has Begun
There are now several sources of evidence for neutrino oscillations. There is evidence from solar neutrino experiments, which observe fewer electron neutrinos than would be consistent with the sun’s energy output [1]. In addition, the recent SNO results indicate that there is a nonelectron flavor active neutrino component in the solar flux [2,3]. Evidence also comes from experiments studying ne...
متن کاملConverting the Kentucky Wilderness
The rural central Kentucky landscape today appears as open, rolling bluegrass fields, punctuated by relicts of “woodland pasture” and partitioned by stone or board fences, the latter usually painted black. Historic residences often sit back from the road at the end of a long drive, presenting a picture of placidity, prosperity and gracious living. Country roads are organic in quality, often app...
متن کاملMuon Rate in the μ BooNE TPC
Muons are the most numerous charged particles at sea level. The muon flux at ground-level has been measured many times in the past 50 years [1, 2, 3, 4, 5]. When muon decay is negligible (Eμ > 100/ cos θGeV, where θ is the polar angle of the incoming muon), and the curvature of the Earth can be neglected (θ < 70◦), the differential flux across a horizontal surface can be well described by the G...
متن کاملVoices in the Wilderness
Analysis of tissue sections from transurethrally resected bladder tumours using anti-CD3 antibody showed the presence of T lymphocytes in intra-epithelial layers in eight of 12 cases investigated. In a larger group of patients, Tumour Infiltrating Lymphocyte (TIL) growth was established from six of 19 cases using Interleukin-2 (IL-2) and conditioned medium (CM) and resulted in the expansion of ...
