Diatoms as an indicator of pharmaceutical contamination in a freshwater system
(2018)Historically, microalgae have been used as bio-indicators of aquatic health and this can be seen in several studies across the world. Often at the bottom of the food chain, microalgae constitute the primary producer of ... -
Enzymatic hydrolysis of primary paper mill sludge and fermentative production of microbial lipids
(2018)Canada is known for its abundant forests and thriving forest products industry. For every ton of paper produced in mills across the country, approximately 30 kg of dry primary sludge is produced. The dry sludge is then ... -
Estimation of stripping by static immersion test using image processing and machine learning
(2019)Hot Mixed Asphalt (HMA) is one of the most common types of pavement, which exists on the surface of the roads, inside and outside of cities. One of the main destresses in HMA is moisture-related damage, which mainly occurs ... -
Experimental investigation of water entry of a solid object and sand particles
(2023)This thesis presents the results of two different approaches to water entry; first, in Part I, the results of the experimental investigation of the water entry of a solid object, a thick disk in stagnant water, are ... -
Experimental investigations of sand-water coaxial and swirling jets in stagnant water
(2021)Sand jets and particle clouds are found in many engineering applications, such as marine bed capping, dredging material disposal, and discharge of wastewater. A coaxial jet is composed of an inner jet surrounded by an ... -
Extracting lignocelluloses from various spent liquors via adsorption
(2015-10-20)The spent liquors of thermomechanical (TMP) and neutral sulfite semichemical (NSSC) pulping processes contain some lignocelluloses that are recently treated in the waste water of the processes, and thus wasted. In this ... -
Fracture behavior of natural fiber-reinforced cemented paste backfill under mode-I, mode-II, and mode-III loading: Effect of fiber content and fiber length
