Achieving urban water conservation: testing community acceptance

Submitted to Office of Water Research and Technology, U.S. Dept. of Interior.Bibliography: pages 199-205.September 1977.Employing a Q-Sort Factor Analytical Design, this study sought to develop a system for parametric representation of non-linear data structures using data acquired from representative samples of entire communities. The representations are specified in terms of a spatial metric "social space," an analog of psychological space. The defined social space is then characterized and used to define the community action zone which is hypothesized to a zone of community acceptance for those policies falling within its bounds. Such a zone for the communities of Lafayette and Louisville, Colorado was used to define socially and politically feasible water conservation policies for the communities. Policies with the highest feasibility for acceptance were legal restrictions on water use and restrictions on growth and development. The next most feasible were horticultural techniques and economic solutions. Reuse for agricultural purposes also appeared to have some political feasibility. This study demonstrated the usefulness of survey research in delineating viable water conservation programs.OWRT Project no.

Complete and safe resection of challenging retroperitoneal tumors: anticipation of multi-organ and major vascular resection and use of adjunct procedures.

BackgroundRetroperitoneal tumors are often massive and can involve adjacent organs and/or vital structures, making them difficult to resect. Completeness of resection is within the surgeon's control and critical for long-term survival, particularly for malignant disease. Few studies directly address strategies for complete and safe resection of challenging retroperitoneal tumors.MethodsFifty-six patients representing 63 cases of primary or recurrent retroperitoneal tumor resection between 2004-2009 were identified and a retrospective chart review was performed. Rates of complete resection, use of adjunct procedures, and perioperative complications were recorded.ResultsIn 95% of cases, complete resection was achieved. Fifty-eight percent of these cases required en bloc multi-organ resection, and 8% required major vascular resection. Complete resection rates were higher for primary versus recurrent disease. Adjunct procedures (ureteral stents, femoral nerve monitoring, posterior laminotomy, etc.) were used in 54% of cases. Major postoperative complications occurred in 16% of cases, and one patient died (2% mortality).ConclusionsComplete resection of challenging retroperitoneal tumors is feasible and can be done safely with important pre- and intraoperative considerations in mind

Conflict Probe Concepts Analysis in Support of Free Flight

This study develops an operational concept and requirements for en route Free Flight using a simulation of the Cleveland Air Route Traffic Control Center, and develops requirements for an automated conflict probe for use in the Air Traffic Control (ATC) Centers. In this paper, we present the results of simulation studies and summarize implementation concepts and infrastructure requirements to transition from the current air traffic control system to mature Free Right. The transition path to Free Flight envisioned in this paper assumes an orderly development of communications, navigation, and surveillance (CNS) technologies based on results from our simulation studies. The main purpose of this study is to provide an overall context and methodology for evaluating airborne and ground-based requirements for cooperative development of the future ATC system

Paromomyid primate

18 p. : ill. ; 24 cm.Includes bibliographical references (p. 18)."A new species of paromomyid primates is described from the middle Paleocene beds of Kutz Canyon Area, San Juan Basin, New Mexico. Palaechthon nacimienti Wilson and Szalay, new species, is similar to P. alticuspis, the generotype, in size and molar morphology, but shows more primitive proportions between the canine and antemolar teeth. A crushed skull of this species shows the primitively dominant facial cranium of early primates"--P. [1]

What Does It Take to Achieve Equitable Urban Tree Canopy Distribution? A Boston Case Study.

Considerable attention has been paid to the benefits that urban trees provide and recent research has focused on how the distribution of trees in the urban landscape is affected by socioeconomic processes like social stratification, as indicated by associations with income, race, ethnicity, and education. These studies have found marked disparity in urban canopy cover, with primarily low income and minority neighborhoods commonly being underserved. However, few studies have investigated the potential to overcome urban canopy inequities through urban planning and reforestation. This question becomes even more important as many U.S. cities pledge to increase urban canopy cover as part of larger climate change mitigation strategies. Can today’s heavily developed U.S. cities use these tree planting initiatives to increase equity in urban canopy cover while still providing the infrastructure and housing necessary for expected population growth? This case study characterizes the socioeconomic drivers of the current urban canopy cover in Boston, Massachusetts, and further explores the possibility of distributing trees to increase equitable access to environmental justice and ecosystem services, while meeting housing and infrastructure needs. Results suggest that even when tree planting initiatives focus specifically on increasing canopy cover for environmental justice communities, equitable distribution of urban trees is difficult to achieve. Our findings indicate that difficulties arise not only from the expected policy and funding aspects, but also from ecological ones, including the physical availability of tree planting sites in environmental justice communities

Synthesis and characterization of Ca-doped LaMnAsO

We report on our attempt to hole-dope the antiferromagnetic semiconductor LaMnAsO by substitution of the La3+ site by Ca2+. We use neutron and x-ray diffraction, magnetic susceptibility, and transport techniques to characterize polycrystalline (La1−xCax)MnAsO samples prepared by solid-state reaction and find that the parent compound is highly resistant to substitution with an upper limit x≤0.01. Magnetic susceptibility of the parent and the x=0.002(xnom=0.04) compounds indicate a negligible presence of magnetic impurities (i.e., MnO or MnAs). Rietveld analysis of neutron and x-ray diffraction data shows the preservation of both the tetragonal (P4/nmm) structure upon doping and the antiferromagnetic ordering temperature, TN=355±5 K
