Community Mapping: Transforming Thinking and Actions Toward Sustainability

This phenomenological study explored the level of concern regarding issues of sustainability, for individuals residing within one mid-sized Midwestern urban community. Ultimately, this research sought to determine those factors that increase the sense of urgency for some individuals to do more to reduce our global footprint and to create a sustainable future for our children and grandchildren. The participants were chosen via purposeful sampling and the interview process was used for data collection. Several themes uncovered in the study findings were similar to those in the literature review, which include: caring for the environment, making connections within the community, recycling, gardening, and sharing gifts (assets) of each individual. Participants shared their journey in sustainability, which provided insight into what they currently do on a daily basis to care for the environment. To increase their knowledge of sustainability they use the library, television, Internet searches and social media sites. They may also learn from others. In addition, these sustainable practices, when shared, may set the example for others to do more in reducing their global footprint. To support sustainability, community mapping can be a valuable tool to identify recycling centers, farmer’s markets, local suppliers of green products, and other essential locations. Whether hard copy maps, Internet sites or applications (apps) for Apple I-devices or Android devices; community mapping can serve individuals who want to conserve the earth’s resources

PARTICLE VELOCITY MEASUREMENT BY HOLOGRAPHY

A double pulsed holography was used to measure the particle velocity and velocity distribution. Semiautomatic technique has been developed at the Department of Physics, Technical University Budapest and used to evaluate the hologram. The velocity of the particle at all points in the sample volume can be measured with high accuracy

Results from the Palo Verde neutrino oscillation experiment

The ν̅e flux and spectrum have been measured at a distance of about 800 m from the reactors of the Palo Verde Nuclear Generating Station using a segmented Gd-loaded liquid scintillator detector. Correlated positron-neutron events from the reaction ν̅ep→e+n were recorded for a period of 200 d including 55 d with one of the three reactors off for refueling. Backgrounds were accounted for by making use of the reactor-on and reactor-off cycles, and also with a novel technique based on the difference between signal and background under reversal of the e+ and n portions of the events. A detailed description of the detector calibration, background subtraction, and data analysis is presented here. Results from the experiment show no evidence for neutrino oscillations. ν̅e→ν̅x oscillations were excluded at 90% C.L. for Δm2>1.12×10-3 eV2 for full mixing and sin22θ>0.21 for large Δm2. These results support the conclusion that the observed atmospheric neutrino oscillations do not involve νe

Neutron production by cosmic-ray muons at shallow depth

The yield of neutrons produced by cosmic ray muons at a shallow depth of 32 meters of water equivalent has been measured. The Palo Verde neutrino detector, containing 11.3 tons of Gd loaded liquid scintillator and 3.5 tons of acrylic served as a target. The rate of one and two neutron captures was determined. Modeling the neutron capture efficiency allowed us to deduce the total yield of neutrons $Y_{tot} = (3.60 \pm 0.09 \pm 0.31) \times 10^{-5}$ neutrons per muon and g/cm$^2$. This yield is consistent with previous measurements at similar depths.Comment: 12 pages, 3 figure

Final results from the Palo Verde Neutrino Oscillation Experiment

The analysis and results are presented from the complete data set recorded at Palo Verde between September 1998 and July 2000. In the experiment, the \nuebar interaction rate has been measured at a distance of 750 and 890 m from the reactors of the Palo Verde Nuclear Generating Station for a total of 350 days, including 108 days with one of the three reactors off for refueling. Backgrounds were determined by (a) the $swap$ technique based on the difference between signal and background under reversal of the positron and neutron parts of the correlated event and (b) making use of the conventional reactor-on and reactor-off cycles. There is no evidence for neutrino oscillation and the mode \nuebar\to\bar\nu_x was excluded at 90% CL for \dm>1.1\times10^{-3} eV$^2$ at full mixing, and \sinq>0.17 at large \dm.Comment: 11 pages, 8 figure
