Foraging time activity study of breeding songbirds in a successional white spruce community
(1999)I investigated the amount of time spent on foraging by birds in a successional white spruce community, during semi-monthly time blocks, in the context of flying, singing and other activities. Five hypotheses were tested: ... -
Forest harvesting impacts on forested wetland forest ecosystem function – biogeochemical cycling
(2020)The wetland ecosystem is located at the interface of the atmospheric, terrestrial and water system. It is one of the most biologically diverse ecological landscapes on earth and one of the most important environments for ... -
Forest road location modelling with Dijkstra’s shortest path and ArcGIS
(2019)Road network modelling has great potential to reduce forest road construction and planning costs. Forest roads are the essential means to access forest resources and are one of the most expensive factors in forest ... -
Forest soil characteristics and variability under teak (Tectona grandis Linn.F) plantations and natural forests in Ashanti Region, Ghana
(1998)The variability of forest soil properties and the number of samples required to achieve desired levels of precision for estimation of property means have received little attention in the tropics. Highly variable forest ... -
Forest stand type and forest diversity affect on above ground carbon biomass in Ontario's boreal forest
(2023)Biomass is a renewable organic material that is the living and recently dead organic material synthesized by plants and other organisms (Battles 2015). Quantifying forests and determining their value is an increasingly ... -
Forest structure and small-mammal responses to variable-retention timber harvest in the Cape Breton highlands of Nova Scotia
(2008)American marten ( Martes americana Turton) are endangered in Nova Scotia and the population on Cape Breton Island is critically low. A marten recovery strategy is in place but there are large gaps in information regarding ... -
Formational processes of recent, arsenic rich, ferromanganese lacustrine precipitates in Nova Scotia and Northern Ontario
(2014-01-22)Banded iron - and manganese - rich precipitates were collected from the lake bottoms of Lake Charlotte (Nova Scotia), Lake Shebandowan (Ontario) and Sowden Lake (Ontario). Investigations of study areas at the macro, meso ... -
Formative evaluation of "Humanities 101 : a Lakehead University community initiative" : the perspective of the students
(2006)In the Fall of 2005, the Faculty of Education at Lakehead University implemented a twelve-week program aimed at providing non-traditional students an experience in higher education. The purpose of this study was to ... -
Fostering greater equity and inclusion with plant-based food options in school: a critical inquiry with elementary parents in the Lakehead District School Board
(2022)While there has been increasing attention to equity and inclusion in Ontario schools, school food and drink offerings have yet to be explicitly incorporated in most equity and inclusion policies and practices. With the ... -
Fracture behavior and properties of fiber-reinforced cemented paste backfill under different displacement rates
(2024)Cemented paste backfills (CPB, comprising waste tailings, hydraulic binder, and water) are essential for safe and efficient underground mining production. Once delivered into underground excavations, CPB undergoes complex ... -
Fracture behavior of fiber-reinforced cemented paste backfill under curing pressure
(2022)Due to the rapid strength acquisition rate, relatively high solid content, and sustainable reuse of waste tailings, cement paste backfill (CPB) technology has gradually become a standard practice in underground mining ... -
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
(2024)The mechanical stability of mine backfill materials is crucial for the safety of mining personnel and production efficiency. When placed into mined-out voids, known as stopes, mine backfill materials are required to ... -
A framework for assessing skills training programs for building Indigenous capacity in natural resource development
(2019)Indigenous participation in natural resource development has become an integral part of the advancement of major projects both in Ontario and across Canada. This participation until the most recent decades was limited by ... -
A framework to avoid maloperation of transformer differential protection under geomagnetic disturbances
(2023)Geomagnetically Induced Currents (GICs), which are generated due to Geomagnetic Disturbances (GMDs), can saturate the cores of power transformers and their associated Current Transformers (CTs). To avoid maloperation of ... -
Freeze-thaw effect on selected fecal indicator bacteria : Escherichia coli and Enterococcus faecalis / by Nicole A. Hawdon.
(2008)The survival of two selected fecal indicator organisms, two strains of Escherichia coli, a Gram-negative bacterium, and two strains of Enterococcus faecalis, a Gram-positive bacterium, after freezing and thawing successively ... -
French Canadian adolescents in a minority milieu
(1997)This inquiry describes the lived experience of minority francophone adolescents in Thunder Bay, Ontario. A snowball sampling approach was used to recruit 22 participants for interviews where they were asked to talk about ... -
Frequency domain tuning approach for adaptive feedforward controllers
(2003)Feedforward control provides a means for compensating measurable disturbances before the process output is affected. A novel tuning strategy for tuning feedforward controllers in frequency domain is developed in this ... -
Frequency response based system identification and controller tuning
(1997)A detailed simulation based analysis of different frequency response and transfer function identification techniques are performed and critically studied. Standard closed loop and open loop recursive least squares system ... -
From alpinism to activism: outdoor athletes’ perspectives on ecological and climate learning through their sport
(2022)While climate change education has been studied extensively, the process of environmental and climate learning outside of a structured educational context has seen little study. Previous research has shown the efficacy ...
