Bioarchaeology in Greece: Breathing Life into the Early Helladic and Archaic Skeletal Assemblages from Klenia
(University of Waterloo, 2019-01-15)Rescue excavations between 2014 and 2015 in Klenia, Corinthia, Greece uncovered an assemblage of human skeletal remains from one Archaic (750-479 BCE) and four Early Helladic (2650-2200 BCE) tombs. Until recently, ... -
A bioassessment of the impact of livestock restriction on benthic macroinvertebrate communities in the Grand River watershed in Ontario, Canada
(University of Waterloo, 2015-09-25)Livestock exclusion from streams is a best management practice applied in attempts to improve water quality in the Grand River watershed in Ontario, Canada. Because of the lack of resources, minimal biomonitoring is conducted ... -
Biochemical and Biophysical Investigations of Non-Zinc Dependent Glyoxalase I Enzymes
(University of Waterloo, 2008-09-26)The principal methylglyoxal (MG)-detoxifying system in most living organisms is the two metalloenzyme Glyoxalase system. Glyoxalase I (GlxI) initially converts the non-enzymatically formed MG-GSH hemithioacetal to the ... -
Biochemical and Microbiological Investigations of Inhibitors for β-Lactamases from Human Pathogenic Bacteria
(University of Waterloo, 2019-04-30)The majority of antibiotics prescribed for treatment of bacterial infections are β-lactam antibiotics. Resistance to these has evolved in a few different ways, notably by regulating permeability and by the expression of ... -
Biochemical Characterization and Optimization of RNA Aptamers Bound to Hoechst Dye Derivatives
(University of Waterloo, 2023-08-09)Ribonucleic acid (RNA) aptamers are single-stranded nucleic acids that are typically selected through a process known as Systematic Evolution of Ligands by EXponential Enrichment (SELEX). These oligonucleotides can bind ... -
Biochemical Characterization of Fluorophore-Binding Nucleic Acids
(University of Waterloo, 2022-09-27)Aptamers, single stranded RNA or DNA that bind to target ligands with high affinity and specificity, have a wide range of applications, from therapeutics to biosensing, which makes biochemical characterization of the utmost ... -
Biochemical Investigations of L-Methionine gamma-lyase 1 from Trichomonas vaginalis
(University of Waterloo, 2011-12-16)The enzyme L-methionine γ-lyase (MGL) utilizes a pyridoxal-5’-phosphate-cofactor in order to convert L-methionine to α-ketobutyrate, ammonia and methyl mercaptan. MGL is proposed to be a potential drug target since it is ... -
Biochemistry in Bacterioferritin
(University of Waterloo, 2006)Bacterioferritin, an iron storage protein having a 24-subunit quaternary structure, was used as a model for the study of host-guest interactions and guest encapsulation, making use of its spherical cage-like structure. ... -
Biocompatibility Evaluation of Engineered Amino Acid Pairing Peptides for Drug Delivery
(University of Waterloo, 2014-01-27)To ensure the effective and safe use of nanomaterials for medical applications, the biocompatibility of the materials must be tested with particular relevance to the environment in which the material is placed. In ... -
BIOCOMPATIBLE SOLID PHASE MICROEXTRACTION
(University of Waterloo, 2006-12-12)Today’s solid phase microextraction (SPME) is a well known technique that combines knowledge from different fields in an attractive, efficient, and economic way. The development of SPME has seen huge growth since its ... -
Biodiesel Energy in Small Island Developing States: Addressing Challenges to Development
(University of Waterloo, 2010-06-11)Petroleum-based fuel dominates the global energy system despite the fact that this resource is diminishing. Additionally, Small Island Developing States (SIDS) face a number of challenges to development such as resource ... -
Biodiversity Citizen Science Data Production Through iNaturalist: An Anthropological Exploration
(University of Waterloo, 2023-05-04)iNaturalist is a common mobile application used in biodiversity citizen science projects and education. The application lets laypeople of all levels of expertise submit species ‘observations’ that can include correlating ... -
Bioenergetics of mixotrophic metabolisms: A theoretical analysis
(University of Waterloo, 2019-08-29)Many biogeochemical reactions controlling surface water and groundwater quality, as well as greenhouse gas emissions and carbon turnover rates, are catalyzed by microorganisms. Representing the thermodynamic (or bioenergetic) ... -
Biofilm Dynamics in Drinking Water Biofiltration & Downstream Nanofiltration Biofouling
(University of Waterloo, 2018-05-17)Natural organic matter (NOM) is a concern in many surface waters and must be removed by water treatment processes for cost-effective production of safe and aesthetically pleasing drinking water. Biological filtration is ... -
Biofiltration in Drinking Water Treatment: Reduction of Membrane Fouling and Biodegradation of Organic Trace Contaminants
(University of Waterloo, 2010-02-17)The goal of drinking water treatment is to produce and deliver safe water to the consumers. To achieve these objectives water treatment plants are designed based on the concept of the multibarrier approach which combines ... -
Biofiltration-based “green technology” as a techno-ecological nature-based solution for drinking water treatment and climate change resilience
(University of Waterloo, 2022-06-02)While drinking water treatment process design is based on current and anticipated source water quality, changing climate makes it increasingly difficult to anticipate drinking water source quality and treatability. Although ... -
Biogas Purification: H2S Removal using Biofiltration
(University of Waterloo, 2010-08-31)Biogas, composed principally of methane, has limited use in energy generation due to the presence of hydrogen sulphide (H2S). Biogas cannot be burned directly in an engine as H2S present causes corrosion in the reaction ... -
