PAndAS' progeny: extending the M31 dwarf galaxy cabal
(2011-02-14)We present the discovery of five new dwarf galaxies, Andromeda XXIII-XXVII, located in the outer halo of M31. These galaxies were found in the second year of data from the Pan-Andromeda Archaeological Survey (PAndAS) of ... -
Parental Factors That Affect the Connectedness to Nature of Pre-School Aged Children in Halifax, Nova Scotia
(2022-04)Time spent in nature has been found to promote a connectedness to nature (CTN) in both children and adults (Gifford & Nilsson, 2014; Deville, 2021). However, it has been found that people in North America are spending ... -
Parental knowledge of attention-deficit hyperactivity disorder and opinions of treatment options: Impact on enrolment and adherence to a 12–month treatment trial
(Canadian Psychiatric Assn, 1999-12)No abstract available. -
Particle formation and growth at five rural and urban sites
(2010)Ultrafine particle (UFP) number and size distributions were simultaneously measured at five urban and rural sites during the summer of 2007 in Ontario, Canada as part of the Border Air Quality and Meteorology Study ... -
Partition of Uranium in Four Canadian Examples of Mississippi Valley Type Base Metal Deposits: Pine Point, N.W.T.; Polaris, N.W.T.; Newfoundland Zinc, Newfoundland; and Gay's River, Nova Scotia
(1977-12)Fission track analyses of minerals host rocks, and fission track mapping of uranium in samples from four Canadian Mississippi Valley type deposits, indicates that uranium concentrations in these samples are very minute ... -
A passive nonlinear digital filter design which facilitates physics-based sound synthesis of highly nonlinear musical instruments
(Acoust. Soc. America through AIP, 1997-02)Recent work has led to highly efficient physics-based computational models of wave propagation in strings, acoustic tubes, membranes, plates, and rooms using the digital waveguide filter, the 2-D digital waveguide mesh, ... -

Patch Dynamics of a Phytophagous Mite Population Effect of Number of Subpopulations
(1991)I conducted a field test of the hypothesis that the dynamics of a predator-prey interaction should be affected by the number of interacting subpopulations within an assemblage. I used a "successful" biological control ... -

Pedestrianizing Norma Eddy Lane: An Analysis of Transport Mode and Safety
(2023-04)This study examines the numerical distribution of users of the north end of Norma Eddy Lane by travel mode. The site, located on the north end of the Dalhousie University Sexton Campus, in between the Ralph M. Medjuck ... -
Perceived Barriers Impacting Participation of Dalhousie University Residents in Waste Diversion Programs
(2013-04)The purpose of this study is to identify the perceived barriers affecting participation in the waste diversion program, Dump and Run, and to provide recommendations on how to increase resident input. The study characterizes ... -
Perceptions of Climate Change: How Dalhousie students conceptualize climate change and the role of faculty in promoting awareness
(2018-04)In an attempt to underline areas within Dalhousie University's schooling that are currently lacking climate change related education, students across multiple faculties were surveyed to identify knowledge gaps in faculty ... -
Performance of a spin-based insulated gate field effect transistor

Periodicity and pitch perception
(1991-10)There has been experimental evidence pointing to at least two pitch mechanisms, the first involving low-order harmonics that are resolved along the basilar membrane, and the second a periodicity mechanism that depends only ... -
