Phytoplankton Growth and Light-Absorption as Regulated by Light, Temperature, and Nutrients
(1991-12)Numerous studies of the growth of phytoplankton in the laboratory have demonstrated the dependence of cellular pigment concentration and growth rate upon light intensity, photoperiod, temperature, and nutrient supply. These ... -
Places of Refuge in Jamaica: Identifying Prospective Site Suitability through an Analysis of Environmental, Socioeconomic, and Physical Criteria [graduate project]
(2015-03-03)Marine transportation is a predominant industry worldwide and has been experiencing increases in growth in the past several decades. Technological advances have led to improvements in safety and efficiency, which have ... -
Plasmons in disordered, two-component, quasi-two-dimensional electron systems
(1989-08/15)The authors investigate the effect of elastic scattering of electrons on the properties of plasmons in a disordered, two-component, quasi-two-dimensional electron gas. Numerical results are given for dispersion relations ... -

"Pock Marks" in Nearshore Sands: Observations During Sandyduck97.
(2000-04-15)Previous bedform research has described different ripple types forming in varying hydrodynamic conditions and used ripple geometry within sedimentary rocks to infer the paleoenvironmental conditions during the ripple ... -
Polar Bear Diets and Arctic Marine Food Webs: Insights from Fatty Acid Analysis
(2008-11)We used quantitative fatty acid signature analysis (QFASA) to examine the diets of 1738 individual polar bears (Ursus maritimus) sampled across the Canadian Arctic over a 30-year span. Polar bear foraging varied over ... -
The Polar Invasion: An Examination of Canadian Policy Perspectives Associated with Arctic Governance
(2014-02-17)The effects of climate change on Arctic sea ice have created unprecedented international interest in accessing the Northwest Passage as a cost efficient alternative for shipping between the Pacific and Atlantic Oceans. ... -
Policy and Behaviour: Exploring Energy Use by Computers in the Marion McCain Building
(2008-04)In an era of increasing concern about environmental integrity and stability, all sectors of society including individuals, institutions, industry and government are re-examining their relationship with the environment. ... -
Pollen limitation of plant reproduction: Ecological and evolutionary causes and consequences
(2004-09)Determining whether seed production is pollen limited has been an area of intensive empirical study over the last two decades. Yet current evidence does not allow satisfactory assessment of the causes or consequences of ... -
A Pollen-Stratigraphic Study of Late-Quaternary Vegetational Change at Porter's Lake, Nova Scotia, with Reference to Marine Intrusion
(1986-04-15)Late-Quaternary sea level rise has caused two marine intrusions into Porter's Lake, Nova Scotia (Smith 1984), resulting in an interesting ecological history. Stratigraphic studies of the lake include work on diatoms and ... -
Polyaniline Electrode Activation in Li Cells
(The Electrochemical Society, 2020-04-17)Polyaniline (PANi) can be used as an electroactive organic cathode material in Li-cells with multiple redox states. The theoretical specific capacity of the emeraldine base (PEB) is 150 mAh g−1. In this study, we show how ... -

Polytropic model fits to the globular cluster NGC 2419 in Modified Newtonian Dynamics
(2011-10-18)We present an analysis of the globular cluster NGC 2419, using a polytropic model in Modified Newtonian Dynamics (MOND) to reproduce recently published high quality data of the structure and kinematics of the system. We ...
