Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Transcriptomic responses to Marteilia sydneyi infection in the Sydney rock oyster Saccostrea glomerata
No full textFunding: This research was funded by Higher Degree by Research candidate support funding from Griffith University to N. Nenadic, I. Bar, and C. McDougall. This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.Marteilia sydneyi, an ascetosporean parasite, is the causative agent of Queensland Unknown (QX) disease in Saccostrea glomerata. QX disease outbreaks often lead to high mortality rates and considerable population losses. Investigating molecular host/parasite interactions is imperative to better understand how S. glomerata mounts immune defences and to explore whether M. sydneyi evades host responses. This study aims to investigate S. glomerata's response to M. sydneyi infection through differential gene expression analysis to uncover immune mechanisms and potential markers for resistance. RNA sequencing and differential gene expression analysis revealed widespread transcriptional changes between infected and non-infected oysters. Genes involved in pathogen recognition and immune response signalling, such as galectin-4-like and G-protein coupled receptors, were significantly differentially expressed in infected S. glomerata, suggesting involvement in the host's immune responses. The upregulation of cytochrome P450 family genes indicates an enhanced detoxification response to infection-induced stress. However, extracellular superoxide dismutase, a gene previously implicated in the oxidative stress response to pathogens, was significantly downregulated, suggesting potential suppression of oxidative burst defence mechanisms. These results reveal the complex nature of S. glomerata's response to M. sydneyi infection, and possible suppression or evasion of host defences by the parasite. The study also identifies multiple genes that likely play crucial roles in the molecular responses and defence mechanisms of S. glomerata to M. sydneyi infection. The identification of these genes provides potential target genes for future studies and possible biomarkers for breeding QX-resistant oyster lines.Peer reviewe
NMR and LC-MSn coupled with pharmacological network analysis for the assessment of phytochemical content and biopharmaceutical potential of Carapa procera extracts
No full textThe methanolic and water extracts of Carapa procera leaves and stem barks were screened for their phytochemical content using a multi-technique approach. The extracts were also assessed for their in vitro antioxidant capacity along with their anti-diabetic (α-amylase, α-glucosidase), anti-tyrosinase, anti-elastase and anti-cholinesterase (AChE, BChE) activities. Furthermore, antibacterial and antifungal effects were determined against several bacterial and fungal strains. Data Integration Analysis for Biomarker discovery using Latent components (DIABLO) integrative analysis was conducted on collected data to determine the influence of extraction solvents and plant parts on phytochemical content, antioxidant properties and enzyme inhibitory properties of C. procera samples. Additionally, the major identified compounds were screened as modulators of multiple pathways involved in human diseases via Gene Ontology (GO) enrichment analysis. Results showed that methanolic stem bark extract exhibited the most potent ABTS scavenging, Cu2+ and Fe3+ reducing power, total antioxidant capacity and Fe2+ chelating power and displayed the highest total flavanol content. Methanolic extracts of leaves and stem barks were abounded with phenolics and had the greatest anti-AChE, anti-BChE, anti-tyrosinase and anti-elastase activities. A significant antifungal activity was observed, with the lowest minimum inhibitory concentration and minimum fungicidal values of 0.07 and 0.15 mg/mL, respectively. DIABLO integrative analysis suggested that the phytochemical content and biological activities varied significantly within the plant parts and were influenced by types of solvent used. GO enrichment analysis on the main bioactive compounds showed modulation of multiple pathways associated with cancer. Obtained results demonstrated that stem bark and leaves of C. procera can be considered as promising sources of bioactive molecules with high pharmacological values
Intern experience at CH���M Hill, Inc.: an internship report
No full textIncludes author's vita"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc.
during the period September 1975 through May 1976 is presented. During this nine month
internship the author worked as an Engineer II in the Industrial Processes discipline of this
large consulting engineering firm... The author's prime responsibility was as one of three
lead design engineers on the design of a large wastewater treatment facility for a pulp mill
in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design
of individual treatment units and associated piping and pumping. The purpose of the project
was to provide wastewater treatment capabilities that would satisfy the effluent limitations
(standards) imposed upon the mill by the State of Washington Department of Ecology and the
U.S. Environmental Protection Agency. The author's assignment also entailed necessary
interaction with the project manager and other CH���M HILL design engineers and support staff
members, the client's representatives, and representatives of two other consulting engineering
firms working on the project. Thus, the internship position at CH���M HILL provided considerable
experience coordinating the author's work with the work of other engineers, guiding the design
and administrative efforts of a support staff, and interacting regularly with the client and
other consulting firms. This broad exposure to a variety of engineering and organizational
problems provided a valuable educational experience
Transition to turbulence in a qblique shock-wave/boundary-layer interaction at M=15
No full textDirect numerical simulations are carried out for different forcing techniques to trigger transition during the interaction between an oblique shock-wave and a laminar boundary-layer at M = 1.5. Three forcing methods are used: a) forcing of oblique unstable modes, whose shape and behaviour are determined by the local linear stability theory, b) broadband free-stream acoustic disturbances, and c) a cold plasma flow control device. While the oblique-mode breakdown is dominant for low-amplitude forcing, long streaky structures drive the transition process in a high-amplitude disturbance environment. LES are also performed on the experimental setup by the Institute of Theoretical and Applied Mechanics (ITAM) from Novosibirsk State University with cold plasma actuation. As well as the disturbance type, the effect of Reynolds number and forcing amplitude will be investigated
