Non-Covalent Interactions in Molecular Crystals: Exploring the Accuracy of the Exchange-Hole Dipole Moment Model with Local Orbitals
(American Chemical Society, 2018) -
Non-linear genetic isolation by distance: implications for dispersal estimation in anadromous and marine fish populations
(2007)Indirect genetic approaches such as those based on the association between genetic and geographic distance (isolation by distance, IBD) may provide one of the best means of estimating dispersal in marine systems. We ... -

Non-Occurrence of Free-Living Paramoeba-Invadens in Water and Sediments of Halifax Harbour Nova Scotia Canada
(1989)Seawater and sediment samples from various sites in or near Halifax Harbour were cultured for Paramoeba as were tissues of the natural sea urchin host Stronglyocentrotus droebachiensis sampled from Halifax Harbour. An ... -
Nonbreeding-Season Drivers of Population Dynamics in Seasonal Migrants: Conservation Parallels Across Taxa
(2009-12)For seasonal migrants, logistical constraints have often limited conservation efforts to improving survival and reproduction during the breeding season only. Yet, mounting empirical evidence suggests that events occurring ... -
Nonlinear Identities for Bernoulli and Euler Polynomials
(2018)It is shown that a certain nonlinear expression for Bernoulli polynomials, related to higher-order convolutions, can be evaluated as a product of simple linear polynomials with integer coefficients. The proof involves ... -
Nonlocal exchange energy of many-fermion systems of arbitrary dimensionality and interparticle interaction
(1986-11/15)The exchange contributions to the ground-state energy of an inhomogeneous many-fermion system of arbitrary dimensionality are calculated. Explicit results are given for both the local-density approximation and the lowest-order ... -

Nonpoint source pollution and diadromous fish restoration: An analysis of coastal watershed management strategies and their effectiveness
(2011-11-15)Human development has had damaging effects on coastal watersheds and estuarine environments worldwide. This paper considers the impacts of nonpoint source pollution (NPS) on these environments. Urbanization and agricultural ... -
North American pollution outflow and the trapping of convectively lifted pollution by upper-level anticyclone
(2005-05)No abstract available. -
A note on the Aristotelian origin of Popper's demarcation criterion together with its application to Atlantic Canada's fisheries
(2012-03-26)It has not always been realised that Karl Popper's demarcation criterion, the criterion he uses to distinguish an empirical science from its 'metaphysical' complement involves an interpretation of the classical theory of ... -
Nova Scotia’s low-bush blueberry industry: Identified areas of concern, what needs done and visions for the future
(2009-04)The low-bush blueberry industry is Nova Scotia’s most important agricultural industry, occupying the largest area under horticultural production and contributing the most economically. The blueberry industry has become ... -
Nucleotide sequence of 5S rDNA and localization of the ribosomal RNA genes to metaphase chromosomes of the Tilapiine cichlid fish, Oreochromis niloticus
(2000-10)In this study, we report the cloning and nucleotide sequence of PCR-generated 5S rDNA from the Tilapiine cichlid fish, Oreochromis niloticus. Two types of 5S rDNA were detected that differed by insertions and/or deletions ... -
Nucleotide sequence, genomic organization and evolution of a major repetitive DNA family in tilapia (Oreochromis mossambicus/hornorum )
(1989)A highly repetitive DNA sequence from tilapia (Oreochromis mossambicus/hornorum ) has been cloned and sequenced. It is a tandemly arrayed sequence of 237 bp and constitutes 7% of the fish genome. The copy number of the ... -
The nucleus of the Sagittarius dSph galaxy and M54: a window on the process of galaxy nucleation
(2008-09-01)We present the results of a thorough study of the nucleus of the Sgr dwarf spheroidal galaxy and of the bright globular cluster M54 that resides within the same nucleus (Sgr,N). We have obtained accurate radial velocities ... -
O-3, Noy, and Nox/noy in the Upper Troposphere of the Equatorial Pacific

The Oaks Experiments on Organic Management of Turf: Final Industry Report
(Edmonds Landscape and Construction Services Limited, Halifax, Nova Scotia, Canada., 1996-10-30)The Oaks experiments were designed to address practical questions about organic management of turfs (lawns, sports fields etc.), notably: (i) How do we use organic fertilizers and soil-building amendments on turf for maximum ... -
Objectives of marine conservation measures and their use in strategic marine spatial planning in Canada
(2023-05-30)With increasing use of and dependence on the ocean, conflict between human uses and between human use and a healthy marine environment are certain. To address this, efforts to develop ecosystem based management that recognize ... -
Obscured and unobscured active galactic nuclei in the Spitzer Space Telescope First Look Survey
(2004-09)Selection of active galactic nuclei (AGN) in the infrared allows the discovery of AGN whose optical emission is extinguished by dust. In this paper, we use the Spitzer Space Telescope First Look Survey (FLS) to assess what ... -
Observation of a blue shift in the optical response at the fundamental band gap in Ga1-xMnxAs
