Heart Failure in Older Persons: Considerations For The Primary Care Physician
(Canadian Geriatrics Society, 2012-04-18)Heart failure (HF) affects over 500,000 Canadians, with 50,000 new patients diagnosed each year. While mortality from cardiovascular diseases has progressively declined in Canada, the burden of HF is expected to continue ... -
Heat Transfer Analysis of a Between-Panes Venetian Blind Using Effective Longwave Radiative Properties
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2004)Center-glass thermal analysis programs based on one-dimensional models have proved to be exceptionally useful. Recently efforts have been made to extend the analysis to include venetian blinds. It is convenient to model ... -
Heat Transfer Analysis Of Windows With Venetian Blinds: A Comparative Study
(2007-06)The potential to reduce building load and annual energy consumption is widely recognized in the use of shading devices to control solar gain. Consequently, the ability to include and model shading layers in complex glazing ... -
Heterothermy, body size, and locomotion as ecological predictors of migration in mammals
(Wiley, 2022-01)Migration is ubiquitous among animals and has evolved repeatedly and independently. Comparative studies of the evolutionary origins of migration in birds are widespread, but are lacking in mammals. Mammalian species have ... -
Heuristic Evaluation for Gameful Design
(Association for Computing Machinery, 2016-10-16)Despite the emergence of many gameful design methods in the literature, there is a lack of evaluation methods specific to gameful design. To address this gap, we present a new set of guidelines for heuristic evaluation of ... -
Heuristic Search Strategy for Transforming Microstructural Patterns to Optimal Copolymerization Recipes
(Wiley, 2018-03-12)Manipulation and optimization of copolymer microstructure for tailoring final properties is of great importance in macromolecular science and engineering. Uncovering the complexities of the interrelationships between ... -
Hg2+ detection using a phosphorothioate RNA probe adsorbed on graphene oxide and a comparison with thymine-rich DNA
(Royal Society of Chemistry, 2016-06-21)Mercury is a highly toxic heavy metal and many DNA-based biosensors have been recently developed for Hg2+ detection in water. Among them, thymine-rich DNA is the most commonly used for designing Hg2+ sensors. However, the ... -
Hierarchical Data Analysis for the Characterization of Polymeric Materials: Linking Measurements and Statistical Methodology
(ASEE, 2021-01-01)As future chemical engineers, it is important that students be able to identify and quantify sources of error. A statistical analysis technique that is often overlooked is hierarchical design methodology, which allows for ... -
Hierarchical RLE level set: A compact and versatile deformable surface representation
(Association for Computing Machinery, 2006-01)This article introduces the Hierarchical Run-Length Encoded (H-RLE) Level Set data structure. This novel data structure combines the best features of the DT-Grid (of Nielsen and Museth [2004]) and the RLE Sparse Level Set ... -
High Throughput Sequencing of MicroRNA in Rainbow Trout Plasma, Mucus, and Surrounding Water Following Acute Stress
(Frontiers, 2021-01-13)Circulating plasma microRNAs (miRNAs) are well established as biomarkers of several diseases in humans and have recently been used as indicators of environmental exposures in fish. However, the role of plasma miRNAs in ... -
High throughput solid phase microextraction: A new alternative for analysis of cellular lipidome?
(Elsevier, 2017-02-01)A new SPME method for untargeted lipidomic study of cell line cultures was proposed for the first time. In this study the feasibility to monitor changes in lipid profile after external stimuli was demonstrated and compared ... -
Higher intake of fish and fat is associated with lower plasma s-adenosylhomocysteine: a cross-sectional study
(Elsevier, 2017-10-02)Several B-vitamins act as co-factors in one-carbon metabolism, a pathway that plays a central role in several chronic diseases. However, there is a lack of knowledge of how diet affects markers in one-carbon metabolism. ... -
Highly polarized carbon nano-architecture as robust metal-free catalyst for oxygen reduction in polymer electrolyte membrane fuel cells
