A cross-sectional examination of aging, alcohol use, and cognitive health in the Canadian longitudinal study of aging (CLSA) baseline data
(2020)
Age, sex, and alcohol use have been identified as factors that influence cognition. The present
study aimed to replicate and extend these findings by examining the effects of age, sex, alcohol
use, and their interactions ...
Interaction of lignin derivatives with polymers, ions and soft surfaces in aqueous systems
(2021)
Lignin is one of the most abundant biopolymers on earth which has recently gained considerable
attention due to its unique potentials to be used in many applications. Many efforts have been made
in improving the compatibility ...
Carboxyalkylated cullulose nanocrystals for novel applications
(2021)
Cellulose nanocrystals (CNC), rigid rod-like nanoparticles, are derived from cellulose through acid
hydrolysis and are considered as emerging nanomaterials according to their beneficial properties
and commercial availability. ...
Towards machine learning enabled future-generation wireless network optimization
(2020)
We anticipate that there will be an enormous amount of wireless devices connected
to the Internet through the future-generation wireless networks. Those wireless devices vary
from self-driving vehicles to smart wearable ...
Male outdoor educators’ understandings of masculinity in practice: a North American case study
(2021)
This exploratory, single embedded case study examined male outdoor educators’ understandings
of masculinity in the field and how such notions impact their practices. Data were collected via
interviews (n = 18), observations ...
Impact of physicochemical properties of lignin-based polymers on their flocculation and adsorption performance
(2021)
Industrial and municipal effluents contain colloidal charged particles, dissolved salts, heavy metals
and other impurities, which may represent varied health risks and must be removed before
discharge into the environment. ...
Narcissism predicts facial muscle reactivity during a body comparison threat: the role of personality in shaping affiliative behaviour
(2021)
The facial feedback hypothesis suggests that individuals automatically activate facial
muscles that are congruent with an expresser’s facial display, which in turn results in a congruent
emotional experience within ...
Drought effects on soil enzyme activity
(2021)
Soil extracellular enzyme activity (EEA) is a strong predictor for soil health. EEA cycle
nutrients within terrestrial systems, processing carbon, nitrogen, and phosphorous, while also
mineralizing and stabilizing gas. ...
Sulfo-functionalization of lignin and its impact on the stabilization of colloidal systems
(2021)
Lignin macromolecules, derived from renewable biomass resources, have gained extensive interest
during the past decade as a sustainable substitute for synthetic oil-based materials. The main goal
of this dissertation was ...
Medical applications of fluorine-19 and hyperpolarized xenon129 magnetic resonance imaging
(2020)
Multinuclear magnetic resonance imaging (MRI) is currently under extensive
development. Although conventional proton MRI is mostly known as an anatomical medical
imaging modality with an excellent soft tissue contrast, ...
