Storey-based stability of steel frames subjected to post-earthquake fire
(Fire Technology, 2020-02)Post-earthquake fires occur after earthquakes and have commonly been encountered throughout history. The fires are particularly deadly and threaten the stability of buildings as possible structural damages caused by seismic ... -
Storey-based stability of unbraced steel frames under piece-linear temperature distributions
(Elsevier, 2019-05-21)There are many cases where the elastic modulus of a structural member will vary longitudinally, such as when a steel column is heated by fire. In such a case, the fire can compromise the integrity of the structural frame. ... -
Storey-based stability of unbraced structural steel frames subjected to variable fire loading
(Elsevier, 2018-08-01)Structural steel has poor fire resistance properties and often requires thermal protection. Passive thermal protection systems such as insulation for steel members by application of spray-applied fire-resistance materials ... -
Straightforward Synthesis and Evaluation of Polymeric Sensing Materials for Acetone Detection
(Wiley, 2020-04-02)Three polymeric materials (polyaniline, polypyrrole, and poly(methyl methacrylate)) have been selected, prepared and evaluated for potential use in acetone sensing (for possible diabetes-related applications). Of the ... -
Strain rate sensitivities of deformation mechanisms in magnesium alloys
(Elsevier, 2018-08-01)Strain rate sensitivity (SRS) is an important material property that governs the rate dependent mechanical behaviors associated with deformation rate changes, creep, stress relaxation, formability, etc. The variety of ... -
Strategic Decision-making about Travel during Disease Outbreaks: a Game Theoretical Approach
(The Royal Society, 2018-08-20)Visitors can play an important role in the spread of infections. Here, we incorporate an epidemic model into a game theoretical framework to investigate the effects of travel strategies on infection control. Potential ... -
Strategic Interactions in Antiviral Drug Use During an Influenza Pandemic
(Public Library of Science, 2017-01-12)Background: The evolution of antiviral drug resistance during influenza pandemics has created widespread concern. Use of antiviral drugs is a main contributor to the evolution of drug-resistant strains. Moreover, there are ... -
Strategic Investigation of the Jackpine Mine Expansion Dispute in the Alberta Oil Sands
(IGI GLOBAL, 2015-03-01)The Graph Model for Conflict Resolution (GMCR) methodology is employed to ascertain strategic insights into a serious conflict over environmental concerns connected to the expanded exploitation of oil sands at the Jackpine ... -
Strategies to Address Misestimation of Energy Intake Based on Self-Report Dietary Consumption in Examining Associations Between Dietary Patterns and Cancer Risk
(MDPI, 2019-11-01)The objective of this study was to determine the influence of strategies of handling misestimation of energy intake (EI) on observed associations between dietary patterns and cancer risk. Data from Alberta’s Tomorrow Project ... -
Strategies to support engagement and continuity of activity during mealtimes for families living with dementia; a qualitative study
(BioMed Central, 2015-10-09)Background Mealtimes are an essential part of living and quality of life for everyone, including persons living with dementia. A longitudinal qualitative study provided understanding of the meaning of mealtimes for ... -
Structural and Kinetic Studies on the Potent Inhibition of Metallo-β-Lactamases by 6- Phosphonomethylpyridine-2-Carboxylates
(American Chemical Society, 2018-02-27)There are currently no clinically available inhibitors of metallo-β-lactamases (MBLs), enzymes which hydrolyze β-lactam antibiotics and confer resistance on Gram-negative bacteria. Here we present 6-phosphonomethylpyridi ... -
Structural Consequences of Calmodulin EF Hand Mutations
(American Chemical Society, 2017-02-21)Calmodulin (CaM) is a cytosolic Ca2+-binding protein that serves as a control element for many enzymes. It consists of two globular domains, each containing two EF hand pairs capable of binding Ca2+, joined by a flexible ... -
Structural investigation of a new cadmium coordination compound prepared by sonochemical process: Crystal structure, Hirshfeld surface, thermal, TD-DFT and NBO analyses
(Elsevier, 2019-04)A new nanostructured cadmium complex containing a tridentate Schiff base ligand was sonochemically synthesized and characterized by XRPD, FT/IR, NMR, and single crystal X-ray crystallography. Structural data showed that ... -
Structural Studies of a Complex Between Endothelial Nitric Oxide Synthase and Calmodulin at Physiological Calcium Concentration
(American Chemical Society, 2016-10-25)The small acidic protein calmodulin (CaM) serves as a Ca2+ sensor and control element for many enzymes including nitric oxide synthase (NOS) enzymes that play major roles in key physiological and pathological processes. ... -
