Mitochondrial DNA analysis of ancient hair shafts from the Dakhleh Oasis, Egypt : challenges and recommendations
(2005)To date, there have been no previous reports in the literature on DNA extraction or analysis of ancient human hair. The hair shaft has an extraordinarily stable structure that enables it to remain unchanged for centuries ... -
Mixtures of Metals and Polycyclic Aromatic Hydrocarbons Lead to Complex Toxic Outcomes in the Freshwater Amphipod, Hyalella azteca
(2015)The study of ecotoxicology inevitably must address the fact that toxicants always occur in mixture. Unfortunately, our present state of knowledge in terms of predicting the effects of contaminant mixtures and understanding ... -
MMPI-2 profiles of Lakehead University students / Elizabeth M.R.M. Lettner.
(1993)Until most recently university students were considered to score significantly higher on the MMPI clinical and validity scales, in terms of their mean profiles, than the original normative non-psychiatric sample. According ... -
Mobile miners: work, home, and hazards in Yukon's mining industry
(2015-06-15)This thesis examines the impacts that long-distance commuting operations have for workers in Yukon's mining industry. The Canadian mining industry has transitioned from the traditional Taylorist operations of the twentieth ... -
Mobile ontology-based reasoning and feedback health monitoring system
(2009)As medical technology has developed over the past few decades, the average human life-span has increased and as a side effect, chronic illness has become more prevalent. Many patients now require constant, everyday monitoring ... -
Mobile robot tank with GPU assistance
(2014-01-22)Robotic research has been costly and tremendously time consuming; this is due to the cost of sensors, motors, computational unit, physical construction, and fabrication. There are also a lot of man hours clocked in for ... -
Modal identification of time-varying structures using the blind source separation techniques
(2016)In last few decades, Structural Health Monitoring (SHM) has been an indispensable subject in the field of vibration engineering. With the aid of modern sensing technology, SHM has garnered significant attention towards ... -
Model of posttraumatic stress reactions to sexual abuse in females / by Suzanne L. Barker-Collo.
(1997)Sexual abuse is identified by the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (4th edition) (DSM-IV, APA, 1994) as a possible precipitator of Posttraumatic Stress Disorder (PTSD). ... -
Model reference adaptive control system using frequency domain performance specifications
(1999)MRAS (Model Reference Adaptive System) to achieve frequency domain performance specifications with different transfer function identification techniques are experimentally studied. Standard open loop and closed loop ... -
Modeling and analysis of limit cycles in buck converters under PI control
(2005)A zero order hold equivalent discrete-time model of the buck converter for computing its large signal frequency-response is developed and experimentally verified. It is shown that with a dc bias and a sinusoidal variation ... -
Modeling and control of a flexible-link manipulator
(2001)The behaviour of a flexible-link robotic manipulator is studied using an experimental apparatus. The system is modeled based on the physical laws governing system dynamics. A non-linear rigid body model is developed which ... -
Modeling and control of various styles of paper machine headboxes
(2003)In this thesis non-linear mathematical models of a typical paper machine approach system with three different styles of headboxes are presented. The non-linear models include the dynamics of the fan pump, DC motor, ... -
Modeling and identification of an axially-moving cantilever beam
(2002)An axially-moving cantilever beam is used to study identification o f time-varying systems. A circuitry for DC motor current control and sensor conditioning is built. The circuitry meets the design requirement of controlling ... -
Modeling groundwater flow and transport of contaminants at a former manufactured gas plant in the midwestern USA
(2013-02-01)The processes used to produce manufactured gas for heating, cooking and lighting purposes in North America from the early 1800s to the mid-1900s have generated by- products such as coal tar containing Monocyclic ... -
Modeling of a high frequency field effect transitor on indium gallium nitride: the metal oxide semiconductor capacitor 1=channel model
(2012-11-10)Quantum devices are an important class of modern heterostructure devices in which quantum effects are exploited directly. A Gallium Nitride high frequency field effect transistor (FET), the subject of this work, exploits ... -
Modeling of PWM boost converters for continuous and discontinuous inductor current modes
(2006)Owing to the relatively more complicated nature of the boost converter with non-ideal elements and operating in continuous and discontinuous inductor current modes, a parsimonious large signal and small signal model for ... -
Modeling the impact of hemlock woolly adelgid under several climate change scenarios
(2023)The hemlock woolly adelgid (Adelges tsugae), or HWA, is a species of insect invasive to eastern North America that has caused significant mortality amongst its hemlock (Tsuga spp.) hosts. Survivorship and subsequent ... -
Modeling the transport of Escherichia coli through the subsurface environment
(2009)Subsurface microbial transport is an important concern in many engineering projects. Expanding the knowledge of this process is important for the risk assessment of sites capable of releasing pathogenic bacterial species ... -
Modeling the woody biomass supply chain for energy production in northwestern Ontario
(2014-01-22)Efficient procurement and optimal utilization of woody biomass for bioenergy production requires a good understanding of biomass supply-chain management. The general objective of this research is to develop decision support ... -
Modeling uncertain demand in wood pellet supply chains: a case study from Northern Ontario
(2015-08-05)This thesis aims to enable Canadian wood pellet producers with the opportunity to offer competitive pricing through optimization of their value chains and supply chains, by employing an operational-level decision support ...
