LITERATURE CITED (2017 - PRESENT) ........................................................................................... 57 3 1. INTRODUCTION 1.1. Overview of Report Organization and Structure In this report we cover activities by the CAP LTER Program (hereafter CAP) during our fourth round of funding (CAP IV), from December 2016 through the present. We have organized the report to follow the NSF guidelines and begin with a brief history and overview of CAP, followed by our central conceptual framework, guiding concepts and how we are organized. We wrap up this introductory section with a discussion of our Diversity, Equity, and Inclusion Social Contract and related activities. Section 2 will detail our site-based research, followed by a summary of our network-level and cross-site activities in Section 3. Our information management efforts will be detailed in Section 4, and Section 5 will cover our education and outreach activities. We conclude the report with information on site/program management (Section 6). Throughout the report, we only cite references that have been published since 2017, for the sake of brevity, but a bibliography of all of CAP's publications may be found here. 1.2. A Brief History of CAP CAP, one of the two urban LTER sites, has been the hub for studies of complex social-ecological systems in the Phoenix metro area (Fig. 1.1) since 1997. Research in CAP I (1997–2004) and CAP II (2004–2010) addressed the question: How does the pattern of development of the city alter ecological conditions of the city and its surrounding environment, and how do ecological consequences of these developments feed back to the social system to generate future changes? From CAP I and II, we learned that land-use legacies have strong effects and that other social variables help explain ecological patterns (e.g., the “luxury effect,” whereby biodiversity is higher in wealthier neighborhoods). Our regional-scale research showed a high degree of heterogeneity in atmospheric deposition, soil nutrients, the nitrogen budget, exposure to toxic hazards, and landscape pattern. We also conducted historic analyses of land use/land cover change (LULCC) and of development and impact of the urban heat island (UHI) effect. In CAP III (2010–2016), we addressed feedbacks between social and ecological systems more explicitly, as mediated through ecosystem services (hereafter ES, defined as the benefits that people derive from Figure 1.1: The 6400 km2 CAP IV study ecosystems). We investigated human behavior and area in central Arizona (red) that outcomes in addition to ecological change, asking: How includes the Phoenix Metro Area do the services provided by evolving urban ecosystems (light gray within the red).

  • Annual Report 2009.Qxd
    RisingRising toto thethe ChallengeChallenge Annual Report 2009 From the Executive Director ESA remains financially sound and programmatically strong. n spite of the difficult economic times the country is I facing, ESA remains financially sound and programmatical- ly strong. Our loyal membership stands near 10,000 and the annual meeting—this year in Albuquerque—attracted 3,599 participants with its excellent program offerings. More than 2,000 institutions worldwide subscribe to one or more of our journals, which continue to be among the most highly cited in our field. Ecology, which is 90 years old this year, was named by the Special Libraries Association (SLA) as one of the top 100 most influential journals in science and medicine in the past 100 years. ESA is engaged in a range of activities that are a testament to the breadth of interests of our members. From congressional briefings on “hot” issues to an energized blog; from specialized ESA file photo Credit: conferences and workshops to galvanizing the community behind data sharing; from the continued evo- lution of our prized diversity program to helping faculty use large scale data sets; and from the ever- increasing influence of our journals, ESA continues to be a vibrant and energized society. ESA is also looking to the future. This year, the Governing Board initiated a long range planning process that will examine the existing activities of the Society and anticipate programs and activities that may be needed in the future. We expect that many of our members will be involved in this effort and be asked to help us ensure that ESA stays relevant far into the future.

Cancer Photodynamic Therapy photosensitizers and their metabolites and photodegradation products are pharmaceutical substances that after treatment will be eliminated from the human body and will eventually reach water bodies. Porphyrins are well established PDT sensitizers and cyanine dyes are promising candidates for the same use. In that way it is important to know how those compounds degrade once they reach water bodies and to find efficient treatment methodologies in case they are persistent. In this paper the simulated solar light photodegradation of a porphyrin (Zinctetraphenylporphyrin) and of a cyanine dye (3,3´-diethylindocarbocyanine iodide) in water was investigated, in the absence and in the presence of the most used photocatalyst for semiconductor photocatalysis: Titanium dioxide (TiO2). We observed that the porphyrin (1x10-3M) did not undergo photodegradation in the absence of photocatalyst and that in its presence the photodegradation process was strongly promoted (60% photodegradation reached after 1 hour of irradiation with 0,01g of TiO2).

Approval does not signify that the contents necessarily reflect the views and policies of the WRC, nor does mention of trade names or commercial products constitute endorsement or recommendation for use. © Water Research Commission ii EXECUTIVE SUMMARY _________________________________________________________________________________ Introduction: Anaerobic treatment of high strength wastewater is a widely accepted practice in the industry due to the fact that it converts the organic pollutants into biogas, which is a mixture of methane and carbon dioxide. As a result, this process leads to the reduction in chemical oxygen demand (COD) of industrial wastewater. Moreover, the biogas produced is a source of energy which can be used in industry or for domestic purposes to offset the ever increasing energy demand. Waste removal and methane yield are the key parameters used in the evaluation of an anaerobic digester (AD) performance in the anaerobic digestion process. The performance of ADs is inadequate in removing some biorecalcitrant wastes effectively. For this reason, advanced oxidation processed (AOPs) such photocatalytic degradation as well as integrated techniques have attracted a lot of interest in the recent years.

  • The Importance of Degradation in the Fate of Selected Organic Compounds in the Environment
    Polish Journal of Environmental Studies Vol. 13, No. 6 (2004), 617-626 Review The Importance of Degradation in the Fate of Selected Organic Compounds in the Environment. Part II. Photodegradation and Biodegradation D. Dąbrowska, A. Kot-Wasik, J. Namieśnik* Department of Analytical Chemistry, Chemical Faculty, Gdańsk University of Technology, 11/12 Narutowicz Str., 80-952 Gdańsk, Poland Received: 12 December 2003 Accepted: 3 June 2004 Abstract Compounds characterized by a slow degradation rate in the environment, i.e. resistant to biodegrada- tion, and photolysis processes, are classified as persistent and have often been considered as potential environmental problems. A more exacting approach recognizes that a compound released to the environ- ment has a tendency to accumulate in one medium more than in others. Hence, partitioning, transport, and transformation rates of any particular compound will differ in each medium. Degradation processes in the dominant medium (where the compound is preferentially accumulated) are expected to have more effect on overall persistence of the measured compound than degradation processes in the other media. Photo- degradation and biodegradation are the degradation processes which can naturaly clean up the environ- ment. Biodegradation is expected to be the major mechanism of loss for most chemicals released into the environment. In this study, photodegradation and biodegradation processes of selected organic pollutants in different media have been reviewed. Keywords: organic pollutants, photodegradation, biodegradation, products of degradation Introduction layers of soil. The intensity of UV radiation depends on many factors, among others, a time of the year, a time of the Persistent organic pollutants (POPs) can cause serious day, latitude, height above the sea level, air density, cloud problems in various environmental compartments due to cover or the size of the ozone hole [1].

  • Dell: Upcycling Ocean Plastics Through Supply Chain Innovation
    For the exclusive use of E. Atolagbe, 2019. case Ravi Anupindi June 18, 2018 Andrew Hoffman W91C21 Dell: Upcycling Ocean Plastics Through Supply Chain Innovation Piyush Bhargava, vice president of global operations at Dell, glanced out his office window. It was a sunny and hot late-August day in Round Rock, Texas in 2017. The sunshine reminded him of the beaches in Indonesia and he could not help but wish he were back there where his goals seemed much more straightforward. It was not long ago that he and his team had been in South Asia surveying the availability of ocean plastics waste, meeting with processors, and enjoying more than their fair share of bakso.i Indeed, the trip to Asia had been a huge success. The team, supported by two University of Michigan Tauber Institute for Global Operations1 interns, had not only proven that incorporating ocean plastics into Dell’s packaging for products was feasible, but that doing so could deliver both meaningful cost savings over conventional sources of plastic and a substantial diversion of waste from the oceans. Bhargava had been happy to see the results but he also knew now that the real work was only just beginning: developing and certifying the supply chain that the team recommended and finding ways to utilize meaningful volumes of ocean plastics, through both Dell products and packaging and creative partnerships with other companies. Even by the most conservative estimates, millions of tons of plastic enter the ocean every year. The scope of the environmental crisis was staggering and it would take a concerted effort well beyond Dell’s scale to fully address the problem.
