Metabolomic Assessment of Dietary Interventions in Obesity by Capillary Electrophoresis Mass Spectrometry
Metabolomic Assessment of Dietary Interventions in Obesity by Capillary Electrophoresis Mass Spectrometry Metabolomic Assessment of Dietary Interventions in Obesity by Capillary Electrophoresis Mass Spectrometry By Karen Phoebe Lam, H.B.Sc., M.Sc. A Thesis Submitted to the School of Graduate Studies in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy McMaster University © Copyright by Karen Phoebe Lam, July 2018 Doctor of Philosophy (2018) McMaster University (Department of Chemisty & Chemical Biology) Hamilton, Ontario TITLE: Metabolomic Assessment of Dietary Interventions in Obesity by Capillary Electrophoresis Mass Spectrometry AUTHOR: Karen Phoebe Lam, H.B.Sc. (University of Toronto), M.Sc. (McMaster University) SUPERVISOR: Professor Philip Britz-McKibbin NUMBER OF PAGES: xxix, 347 ii Abstract Capillary electrophoresis mass spectrometry (CE-MS) is a versatile instrumental method for metabolomics, which allows for comprehensive metabolite profiling of volume-limited biological specimens in order to better understand the molecular mechanisms associated with chronic diseases, including an alarming epidemic of obesity worldwide. Multiplexed CE separations enable high-throughput metabolite screening with quality assurance to prevent false discoveries when combined with rigorous method validation, robust experimental designs, complementary statistical methods, and high-resolution tandem mass spectrometry (MS/MS) for unknown metabolite identification. In this thesis, multiplexed CE-MS technology is applied for both targeted and untargeted metabolite profiling of various biological fluids, including covalently bound thiol-protein conjugates, as well as free circulating metabolites in serum and plasma, and excreted/bio-transformed compounds in urine due to complex host-gut microflora co-metabolism. This work was applied to characterize aberrant metabolic responses of obese subjects in response to dietary challenges, and measure the benefits of dietary interventions that reduce adiposity without deleterious muscle loss. -

The Influence of Electronegativity on Linear and Triangular Three-Centre Bonds
The Free Internet Journal Review for Organic Chemistry Archive for Arkivoc 2020, part iv, 12-24 Organic Chemistry The influence of electronegativity on linear and triangular three-centre bonds Christopher A. Ramsden Lennard-Jones Laboratories, School of Chemical and Physical Sciences, Keele University, Keele, Staffordshire ST5 5BG, United Kingdom Email: [email protected] Received 03-24-2020 Accepted 04-19-2020 Published on line 04-30-2020 Abstract Electronegativity differences between bonding atoms have major effects on the strengths of chemical bonds but they affect two-centre and three-centre bonds in different ways and with different consequences. The effect on two-centre bonds was recognised almost 100 years ago but the influence of electronegativity difference on three-centre bonding has received less attention. Molecular orbital models of three-centre bonding are discussed and their application to the understanding of the properties of three-centre bonded species illustrated. -2.5 X -3.0 + Y Y Ea -3.5 -4.0 -4.5 X Binding Energy Binding + -5.0 Y Y -5.5 -6.0 -4 -2 0 2 4 h (b units) Keywords: Three-centre bonding, electronegativity, hypervalent, nonclassical carbocations, 2-norbornyl cation, xenon difluoride DOI: https://doi.org/10.24820/ark.5550190.p011.203 Page 12 ©AUTHOR(S) Arkivoc 2020, iv, 12-24 Ramsden, C.

Monday Morning, October 19, 2015 Energy Frontiers Focus Topic Willow glass is a new material introduced recently to the market, while nickel is a inexpensive flexible reflective foil. The Corning Willow glass is Room: 211B - Session EN+AS+EM+NS+SE+SS+TF- coated with a molybdenum layer as a reflective back contact layer. By using MoM a single step and a solution deposition method, lower production cost are achievable. For thin film deposition, we used a non-vacuum spin coater (WS650 spin processor, Laurell Technologies) with an optimized spin coat Solar Cells I programming. Annealing took place under vacuum in a RTP furnace while Moderator: Jason Baxter, Drexel University, Chintalapalle time, temperature and ramp functions were varied. The other layers of the Ramana, University of Texas at El Paso device consists of cadmium sulfide n-type window layer and a zinc oxide doped with aluminum transparent top contact layer. Characterization and analysis of the thin films were performed using Raman spectroscopy, 8:20am EN+AS+EM+NS+SE+SS+TF-MoM1 Elevated Temperature scanning election microscope (Zeiss NEON 40), X-ray diffraction (Philipps Phase Stability of CZTS-Se Thin Films for Solar Cells, E.

Source of Atomic Hydrogen for Ion Trap Experiments: Review and Basic Properties
WDS'15 Proceedings of Contributed Papers — Physics, 155–161, 2015. ISBN 978-80-7378-311-2 © MATFYZPRESS Source of Atomic Hydrogen for Ion Trap Experiments: Review and Basic Properties A. Kovalenko, Š Roučka, S. Rednyk, T. D. Tran, D. Mulin, R. Plašil, J. Glosík Charles University in Prague, Faculty of Mathematics and Physics, Prague, Czech Republic. Abstract. The H-atom source was used to produce atomic hydrogen for study of ion-molecule reactions relevant to astrochemistry at low temperatures. H atoms were cooled and formed into an effusive beam, passing through a 22-pole ion trap. Here we present the basic operating principles of the H-atom source and give a review of this apparatus with some calculations of vacuum conditions and parameters of the produced H-atom beam. Introduction Hydrogen is the most abundant element in the Universe [Field et al., 1966]. It is the main component of stars, giant planets and interstellar clouds. Reactions with atomic or molecular hydrogen are important for understanding the processes which occur in the interstellar medium and during the formation of the new stars. There are three isotopes of hydrogen: protium, deuterium and tritium. The reactions of ions with H atoms have to be studied for better understanding of formation and destruction of more complex ions and molecules observed in interstellar medium. There are regions in space called H I and H II regions where hydrogen is mostly neutral in H I regions, rather than ionized or molecular in the H II regions. The atomic hydrogen plays fundamental role in many astrophysical contexts especially in formation H2 molecules [Habart et al., 2005; Sternberg et al., 2014]. -

Abstract The iron and steel industry accounts for 5 % of worldwide CO2 emissions. With 13 MtCO2eq annually, TATA Steel, which employs the traditional blast furnace – basic oxygen furnace steel making route, is one of the largest single point emitters in the Netherlands (and EU). Given the role of steel in present and future society, decarbonizing the steel industry is of paramount importance for a CO2 net-zero society. -

Hydrogen Fuel Cell Vehicles in Tunnels
SAND2020-4507 R Hydrogen Fuel Cell Vehicles in Tunnels Austin M. Glover, Austin R. Baird, Chris B. LaFleur April 2020 Sandia National Laboratories is a multimission laboratory managed and operated by National Technology and Engineering Solutions of Sandia, LLC, a wholly owned subsidiary of Honeywell International Inc., for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-NA0003525. 2 ABSTRACT There are numerous vehicles which utilize alternative fuels, or fuels that differ from typical hydrocarbons such as gasoline and diesel, throughout the world. Alternative vehicles include those running on the combustion of natural gas and propane as well as electrical drive vehicles utilizing batteries or hydrogen as energy storage. Because the number of alternative fuels vehicles is expected to increase significantly, it is important to analyze the hazards and risks involved with these new technologies with respect to the regulations related to specific transport infrastructure, such as bridges and tunnels. This report focuses on hazards presented by hydrogen fuel cell electric vehicles that are different from traditional fuels. There are numerous scientific research and analysis publications on hydrogen hazards in tunnel scenarios; however, compiling the data to make conclusions can be a difficult process for tunnel owners and authorities having jurisdiction over tunnels. This report provides a summary of the available literature characterizing hazards presented by hydrogen fuel cell electric vehicles, including light-duty, medium and heavy-duty, as well as buses. Research characterizing both worst-case and credible scenarios, as well as risk-based analysis, is summarized. Gaps in the research are identified to guide future research efforts to provide a complete analysis of the hazards and recommendations for the safe use of hydrogen fuel cell electric vehicles in tunnels. -
