“…Based on our findings in the 30-cultivars study, we suggested that the relatively lower yields of 4 some of the cultivars studied in Saskatoon could be due to either herbicide damage (herbicide 5 used for weed control), poor willow root extension due to heavy clay soils, a notable winter 6 dieback of some cultivars, moisture regime limitations during the first rotation (Hangs et al, 7 2012b), and low plant-available soil N levels . Our observations from 8 the 30-cultivars study agreed with previous reports that growing degree days (GDD, base 5°C) 9 (Kopp et al, 2001; Moukoumi et al, 2012) was a very important growth limiting factor for 10 willow SRC systems, and the much lower yields observed in the 30-cultivar study adequately 11 corresponded to the lower GDD count at these northern latitudes under Canadian climatic 12 conditions. A similar decrease in willow SRC biomass yield resulting from GDD decrease was 13 previously reported by Kopp et al (2001) In sum, the total amount of C removed from the atmosphere in two full cycles of seven 3-yr 3 willow SRC rotations in the form of ecosystem C and C in harvested biomass averaged 292 and 4 215 Mg C ha -1 (= 6.6 and 4.9 Mg C ha -1 yr -1 ) in the Prairie and the Boreal Plain ecozones of 5 Saskatchewan, respectively (Amichev et al, 2012).…”

Willow (Salix spp.) short‐rotation coppice (SRC) systems are becoming an attractive practice because they are a sustainable system fulfilling multiple ecological objectives with significant environmental benefits. A sustainable supply of bioenergy feedstock can be produced by willow on marginal land using well‐adapted or tolerant cultivars. Across Canada and the northern United States, there are millions of hectares of available degraded land that have the potential for willow SRC biomass production, with a C sequestration potential capable of offsetting appreciable amounts of anthropogenic greenhouse gas emissions. A fundamental question concerning sustainable SRC willow yields was whether long‐term soil productivity is maintained within a multi‐rotation SRC system, given the rapid growth rate and associated nutrient exports offsite when harvesting the willow biomass after repeated short rotations. Based on early results from the first willow SRC rotation, it was found that willow systems have relatively low nutrient demands, with minimal nutrient outputs other than in the harvested biomass. Our overall aim was to summarize the literature and present findings and data from ongoing research trials across Canada and the northern United States examining willow SRC system establishment and viability. The research areas of interest are the crop production of willow SRC systems, above‐ and belowground biomass dynamics and the C budget, comprehensive soil–willow system nutrient budgets, and soil nutrient amendments (via fertilization) in willow SRC systems. Areas of existing research gaps were also identified for the Canadian context.

“…The improved determination of ∆m 2 21 and θ 12 with KamLAND or dedicated post-KamLAND reactor neutrino experiments has been studied also, e.g., in refs.

We explore a novel possibility of determining the solar model parameters, which serve as input in the calculations of the solar neutrino fluxes, by exploiting the data from direct measurements of the fluxes. More specifically, we use the rather precise value of the 8 B neutrino flux, φ B obtained from the global analysis of the solar neutrino and KamLAND data, to derive constraints on each of the solar model parameters on which φ B depends. We also use more precise values of 7 Be and pp fluxes as can be obtained from future prospective data and discuss whether such measurements can help in reducing the uncertainties of one or more input parameters of the Standard Solar Model.

“…The event identification parameter, PID, is then defined according to: (75) and takes values close to unity for CC events and close to zero for NC events. Figure 44 shows that the L010z185i ND CC-like data and MC identifiaction parameter distributions agree well.…”

Cross section measurements for quasi-elastic neutrino-nucleus scattering with the MINOS near detector

The Main Injector Neutrino Oscillation Search (MINOS) is a long baseline neutrino oscillation experiment based at the Fermi National Accelerator Laboratory (FNAL) in Chicago, Illinois. MINOS measures neutrino interactions in two large iron-scintillator tracking/sampling calorimeters; the Near Detector on-site at FNAL and the Far Detector located in the Soudan mine in northern Minnesota. The Near Detector has recorded a large number of neutrino interactions and this high statistics dataset can be used to make precision measurements of neutrino interaction cross sections.The cross section for charged-current quasi-elastic scattering has been measured by a number of previous experiments and these measurements disagree by up to 30%. A method to select a quasi-elastic enriched sample of neutrino interactions in the MINOS Near Detector is presented and a procedure to fit the kinematic distributions of this sample and extract the quasi-elastic cross section is introduced. The accuracy and robustness of the fitting procedure is studied using mock data and finally results from fits to the MINOS Near Detector data are presented.
