Urban Stream Syndrome in a Small Town: A Comparative Study of Sager and Flint Creeks
Full text linkUtilizing rapid bioassessment procedures and aquatic physiochemical techniques, a three-year investigation of Sager and Flint creeks was completed. Bioassessment indices and physiochemical parameters of the 2 streams were compared and the effects of urbanization on both watersheds were assessed. Correlating data concerning land usage in both watersheds and alterations of both streams\u27 geomorphology were also utilized to conclude that Sager Creek shows a higher degree of urban stream syndrome than Flint Creek
Water Quality Assessment of Sager Creek Utilizing Physiochemical Parameters and a Family-Level Biotic Index
Full text linkAn annual rapid bioassessment and physiochemical survey of Sager Creek in Northwest Arkansas was conducted. Sager Creek is a first to second order stream that flows through the city of Siloam Springs, AR. Invertebrate collections and water samples were collected at three different reaches, with the most downstream reach being below the effluent of the Siloam Springs Wastewater Treatment Plant. Benthic arthropods were collected, identified, and counted to produce a family-level biotic index and a family-level index of diversity. Statistical analysis revealed that these indices were significantly different for the effluent- influenced reach. However, this difference could not be correlated to any measured physiochemical parameter
Strigamia fulva Sager 1856
No full textStrigamia fulva Sager, 1856 Synonym: Linotaenia micropus Chamberlin, 1902. References for morphology: Wood 1862, 1865; Meinert 1886 (sub Scolioplanes bothriopus); Chamberlin 1902 (sub Linotaenia micropus); Crabill 1954 b. Taxonomic notes. Described originally as a species of Strigamia, it was variously cited under Linotaenia, Scolioplanes or Tomotaenia. Following Meinert (1886), some authors considered it identical to S. bothriopus, but Crabill (1954 b) re-examined the type material and demonstrated that the two species are distinct. Linotaenia micropus was described by Chamberlin (1902), but practically ignored by subsequent authors, and only registered as valid by Attems (1929). Chamberlin (1961) later recognized it as identical “part. max” with S. fulva, and Mercurio (2010) listed it as a synonym of S. fulva. However, published information on the morphology of S. micropus does not allow a decision as to whether the type specimens belong to S. fulva or S. bothriopus, which have been confused in the past (Crabill 1954 b), therefore the current synonymy is registered here only provisionally. Distribution: eastern part of North America, westwards possibly to Iowa. Published records from other parts of North America need confirmation because of possible confusion with S. bothriopus.Published as part of Bonato, Lucio, Dányi, László, Socci, Antonio Augusto & Minelli, Alessandro, 2012, Species diversity of Strigamia Gray, 1843 (Chilopoda: Linotaeniidae): a preliminary synthesis, pp. 1-39 in Zootaxa 3593 on page 14, DOI: 10.5281/zenodo.21489
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
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
Solar PV Penetration Scenarios for a University Campus in KSA
No full textThe Kingdom of Saudi Arabia (KSA) is committed to transition its fossil fuel-driven electricity generation to that from renewable energy technologies, such as solar photovoltaic (PV) and wind. The need to reduce greenhouse gas emissions has led it to announce an ambitious target of 40 GW of PV power capacity by 2030. The deployment of such a capacity needs to be augmented with analyses to overcome the challenges faced in terms of the technical capability of the country. This work contributes to this goal by investigating the utilisation of solar photovoltaic PV systems to supply medium-size entities such as universities with clean power, displacing the current fossil fuel power supply. Currently, such considerations are not fully addressed in KSA. The study used the University of Jeddah campus electrical load profile, taking into account future power needs. The methodology encompassed modelling the installation of multi-MW PV systems for the university by considering weather conditions, actual university consumption, load segregation, and economics under different development scenarios informed by surveys with decision makers at the university. The results showed that air conditioning loads alone were responsible for 79% of the campus electrical load and that a 4.5 MW PV system is able to supply half of the total campus annual electrical energy consumption of the year of 2019. The optimum scenario showed that utilising grid-connected PVs would decrease the total cost of electricity over the next two decades by 28 to 35 percent and would result in halving the current campus carbon emissions. The analysis concludes that the business-as-usual case is no longer the cheapest option for the campus

Active faulting on the Ninetyeast Ridge and its relation to deformation of the Indo-Australian plate
No full textThe ~4500 km long Ninetyeast Ridge (NER) in the northeastern Indian Ocean crosses a broad zone of deformation where the Indo-Australian plate is fracturing into three smaller plates (India, Capricorn, Australia) separated by diffuse boundaries whose extents are poorly defined. New multichannel seismic reflection profiles image active faults along the entire length of the NER and show spatial changes in the style of deformation along the ridge. The northern NER (0°N–5°N) displays transpressional motion along WNW-ESE faults. Observed fault patterns confirm strike-slip motion at the western extent of the April 2012 Wharton Basin earthquake swarm. In the central NER (5°S–8°S), deformation on WNW-ESE-trending thrust faults implies nearly N-S compression. An abrupt change in fault style occurs between 8° and 11°S, with modest, extension characterizing the southern NER (11°S–27°S). Although extension is dominant, narrow zones of faults with strike-slip or compressional character also occur in the southern NER, suggesting a complex combination of fault motions. At all sites, active faulting is controlled by the reactivation of original, spreading-center formed, normal faults, implying that deformation is opportunistic and focused along existing zones of weakness, even when original fault trend is oblique to the direction of relative plate motion. Observed faulting can be interpreted as India-Australia deformation in the northern NER and Capricorn-Australia deformation in the southern NER. The India-Capricorn boundary is directly adjacent to the northern NER and this juxtaposition combined with a different style of faulting to the east of the NER imply that the ridge is a tectonic boundary
