Regional Geochemical Variations of Upper Cenozoic Volcanic Rocks in the Andes
(1978-03-15)Regional variations in the chemical composition of Miocene-to-Recent volcanic rocks from the Central Andes are investigated on the basis of 260 chemical analyses compiled from the literature in addition to 25 new analyses ... -
A REGIONAL INVESTIGATION OF SCHEELITE OCCURRENCES IN THE MEGUMA QROUP OF NOVA SCOTIA
(1984-04)The scheelite deposits of the Meguma Group of Nova Scotia are found within interbedded veins in the slates and quartzites of the lower Halifax and upper Goldenville Formations. The veins are found at the edge of or within ... -
Regional Mapping and Petrographic Study of a Silurian Gneissic Complex, Belle Cote Road, Cape Breton, Nova Scotia
(1987-04-15)The Leblanc Lake area is located in the central Cape Breton Highlands south of the Cheticamp River. The main study area is situated along Belle Cote Road, one of the numerous logging roads in the region. Mapping at ... -
Regional Response Planning (RRP) for Ship-Source Oil Spills in Canada: Assessing the Implementation Status of Recommendations and Integration into an RRP Framework
(2020-12)In 1995, the National Oil Spill Preparedness and Response Regime (NOSPRR) was established by Transport Canada. Although there has not been a major spill in Canadian waters since NOSPRR was implemented, experts have ... -
Regional-scale effects of eutrophication on ecosystem structure and services of seagrass beds
(2012-09)Using large-scale field surveys across 12 estuaries in two provinces in Atlantic Canada, we analyzed changes in phytoplankton and benthic macroalgal communities as well as the canopy structure of eelgrass beds and quantified ... -
Regioselective Substituent Effects upon the Synthesis of Dipyrrins from 2-Formyl Pyrroles
(Canadian Journal of Chemistry, 2018)The synthesis of symmetric α-free meso-H-dipyrrin hydrobromides from 5-H-2-formyl pyrroles was investigated. The self-condensation produces regioisomeric dipyrrins through the adoption of two mechanistic pathways. The key ... -
Regulation of an Insect Population Under Biological-Control
(1995-01)California red scale is suppressed to very low densities by the parasitoid Aphytis melinus. The system also appears stable. We report on an experimental test of the hypothesis that stability is caused by a refuge for scale. ... -
Relating 139La Quadrupolar Coupling Constants to Polyhedral Distortion in Crystalline Structures
(American Chemical Society, 2015-10-26)A broad series of crystalline lanthanum oxide-based materials has been investigated through high-field 139La solid state nuclear magnetic resonance (ssNMR) spectroscopy and ab initio density functional theory (DFT) ... -
Relating atmospheric and oceanic DMS levels to particle nucleation events in the Canadian Arctic
(2011-11)No abstract available. -
Relating nutrient availability to yield: an examination of lowbush blueberry (Vaccinium anustifolium) resource limitation in Prince Edward Island
(2015-04)This study investigates the role of nutrient availability within the lowbush blueberry (Vacciunium Angustifolium) to add to the current body of knowledge on the role of resource limitation in predicting final yield. The ... -
Relations Between the Sulphide Minerals, Metamorphism, and Deformation in the Faribault Brook Area of the Cape Breton Highlands, Nova Scotia
(1986-04-15)The study area is located within the Jumping Brook Complex which is part of the western Highlands volcanic sedimentary complex. In the Faribault Brook area, the Jumping Brook Complex consists of a unit of pillow basalts ... -
A relationship between heat transfer to sea ice and temperature-salinity properties of Arctic Ocean waters
(1988)It is demonstrated that the characteristic temperature-salinity relationship shown by thermocline waters of the Arctic Ocean can be reproduced using a simple model based on transfer of heat directly from these waters to ... -
The relationship between offspring size and fitness: integrating theory and empiricism
(2013-02)How parents divide the energy available for reproduction between size and number of offspring has a profound effect on parental reproductive success. Theory indicates that the relationship between offspring size and ... -

The Relationship Between Stellar and Black-Hole Mass in Submillimeter Galaxies
(2005-12-20)We analyze deep X-ray, optical and mid-infrared Spitzer observations of the CDF-N/GOODS-N region to study 13 submillimeter-detected galaxies (SMGs) with spectroscopic redshifts (median z=2.2). We find a correlation between ... -
The relationship between urban tree canopy cover and socioeconomic status in urban Halifax
(2018-04)Urbanization has highlighted the importance of vegetation in city environments. The influx of people into city centers are concentrating larger populations into smaller areas, and this is having a negative impact on the ... -
The Relationship of Coastal Drumlins to Barrier Beach Formation Along the Eastern Shore of Nova Scotia
(1984-04-15)The Eastern Shore of Nova Scotia is experiencing post-glacial rise in relative sea level, resulting in a transgressive coastal environment. Drowned estuaries are fronted by eroding drumlin headlands which provide a sediment ... -
Relationships between vertical mixing and photoadaptation of phytoplankton: Similarity criteria
(1984-03)In their natural environment phytoplankton are exposed to fluctuations in incident irradiance due to vertical displacements in the water column induced by turbulent fluid motion. A reaction-diffusion model is analyzed to ...
