Sustainability of Engineered in Arid Lands (seridas)
No full textAyşegül Kibaroğlu is a project team member of an international project entitled Sustainability of Engineered in Arid Lands (SERIDAS), which is led by the scientists from the University of Texas (UT) at Austin and the Houston Advanced Research Center (HARC). Within the framework of this project, which was initially funded by Cynthia and George Mitchell Foundation, Kibaroğlu is collaborating with scientists from the United States, Germany, Brazil, Australia, and Spain, who study the Rivers Euphrates-Tigris, Nile, Rio Grande, Yellow, Murray-Darling, Colorado, Jucar, Limari and São Francisco in order to find out how the rivers will do in the years 2040 and 2060. As part of this project, Ayşegül Kibaroğlu was invited as the visiting scholar by the Lyndon B. Johnson School of Public Affairs, UT, Austin to co-convene a gradute course (policy research project) on sustainable governance of international rivers in 2016

Quantification of Fugitive Reactive Alkene Emissions From Petrochemical Plants With Perfluorocarbon Tracers.
No full textRecent studies demonstrate the impact of fugitive emissions of reactive alkenes on the atmospheric chemistry of the Houston Texas metropolitan area (1). Petrochemical plants located in and around the Houston area emit atmospheric alkenes, such as ethene, propene and 1,3-butadiene. The magnitude of emissions is a major uncertainty in assessing their effects. Even though the petrochemical industry reports that fugitive emissions of alkenes have been reduced to less than 0.1% of daily production, recent measurement data, obtained during the TexAQS 2000 experiment indicates that emissions are perhaps a factor of ten larger than estimated values. Industry figures for fugitive emissions are based on adding up estimated emission factors for every component in the plant to give a total estimated emission from the entire facility. The dramatic difference between estimated and measured rates indicates either that calculating emission fluxes by summing estimates for individual components is seriously flawed, possibly due to individual components leaking well beyond their estimated tolerances, that not all sources of emissions for a facility are being considered in emissions estimates, or that there are known sources of emissions that are not being reported. This experiment was designed to confirm estimates of reactive alkene emissions derived from analysis of the TexAQS 2000 data by releasing perfluorocarbon tracers (PFTs) at a known flux from a petrochemical plant and sampling both the perfluorocarbon tracer and reactive alkenes downwind using the Piper-Aztec research aircraft operated by Baylor University. PFTs have been extensively used to determine leaks in pipelines, air infiltration in buildings, and to characterize the transport and dispersion of air parcels in the atmosphere. Over 20 years of development by the Tracer Technology Center (TTC) has produced a range of analysis instruments, field samplers and PFT release equipment that have been successfully deployed in a large variety of experiments. PFTs are inert, nontoxic, noncombustible and nonreactive. Up to seven unique PFTs can be simultaneously released, sampled and analyzed and the technology is well suited for determining emission fluxes from large petrochemical facilities. The PFT experiment described here was designed to quantitate alkene emissions from a single petrochemical facility, but such experiments could be applied to other industrial sources or groups of sources in the Houston area
AGENDA: Opportunities and Obstacles to Reducing the Environmental Footprint of Natural Gas Development in the Uintah Basin
Full text linkA public workshop to discuss “Opportunities and Constraints to Reducing the Environmental Footprint of Natural Gas Development” was held in Vernal, Utah on October 14, 2010 at the Vernal campus of Utah State University. The workshop was sponsored by Utah State University, The Bingham Energy Research Center; The University of Colorado Natural Resources Law Center; and the Houston Advanced Research Center, Environmentally Friendly Drilling Program.
The meeting included presentations and panel discussions on: Trends and environmental issues related to natural gas development Examples of environmental innovations being used in the Uintah Basin Examples of innovation & tools from outside the Uintah Basin Regulations and environmental policies: friend or foe? A panel discussion with government leaders
The 145 attendees represented a range of regional and local energy industry actors, representatives from local, state, tribal, and federal government agencies, university scientists, and local community residents

Center for Fuel Cell Research and Applications development phase. Final report
Full text linkThe deployment and operation of clean power generation is becoming critical as the energy and transportation sectors seek ways to comply with clean air standards and the national deregulation of the utility industry. However, for strategic business decisions, considerable analysis is required over the next few years to evaluate the appropriate application and value added from this emerging technology. To this end the Houston Advanced Research Center (HARC) is proposing a three-year industry-driven project that centers on the creation of ``The Center for Fuel Cell Research and Applications.`` A collaborative laboratory housed at and managed by HARC, the Center will enable a core group of six diverse participating companies--industry participants--to investigate the economic and operational feasibility of proton-exchange-membrane (PEM) fuel cells in a variety of applications (the core project). This document describes the unique benefits of a collaborative approach to PEM applied research, among them a shared laboratory concept leading to cost savings and shared risks as well as access to outstanding research talent and lab facilities. It also describes the benefits provided by implementing the project at HARC, with particular emphasis on HARC`s history of managing successful long-term research projects as well as its experience in dealing with industry consortia projects. The Center is also unique in that it will not duplicate the traditional university role of basic research or that of the fuel cell industry in developing commercial products. Instead, the Center will focus on applications, testing, and demonstration of fuel cell technology
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
