Photoacoustic investigation of the temperature and magnetic-field dependence of the specific-heat capacity and thermal conductivity near the Curie point of gadolinium
(1995-11/01)The photoacoustic technique was used as a simple but accurate tool to simultaneously determine the specific-heat capacity C and thermal conductivity K of gadolinium in the neighborhood of the Curie point. One polycrystalline ... -
Photochemical processing of organic aerosol at nearby continental sites: contrast between urban plumes and regional aerosol
(2011)As part of the BAQS-Met 2007 field campaign, Aerodyne time-of-flight aerosol mass spectrometers (ToF-AMS) were deployed at two sites in southwestern Ontario from 17 June to 11 July 2007. One instrument was located at ... -
Photochemical Production of Methyl-Iodide in Seawater
(1994-08)It is generally accepted that methyl iodide is a major contributor to the flux of iodine from the ocean to the atmosphere, but its sources in the ocean are largely unknown, an exception being production by certain species ... -
The Photodecarboxylation of Substituted Naphthylmethyl Arylacetate Esters: Synthesis of Naphthylarylethanes
(2019)The synthesis of naphthylarylethanes via the photodecarboxylation of naphthylmethyl arylacetate esters is reported where the aryl group is able to stabilize a charge transfer reaction. The reaction proceeds via intramolecular ... -
Photosynthetic characteristics and estimated growth rates indicate grazing is the proximate control of primary production in the Equatorial Pacific
(1992)Macronutrients persist in the surface layer of the equatorial Pacific Ocean because the production of phytoplankton is limited. Measurements of photosynthesis as a function of irradiance (P-I) provide information on the ... -
Phylogenomic analysis of natural selection pressure in Streptococcus genomes
(2007-08)Background: In comparative analyses of bacterial pathogens, it has been common practice to discriminate between two types of genes: (i) those shared by pathogens and their non-pathogenic relatives (core genes), and (ii) ... -
Physical and biological factors influencing mussel (Mytilus trossulus, M. edulis) settlement on a wave-exposed rocky shore
(1996)Settlement rates of mussels Mytilus trossulus and M. edulis on artificial collectors (aquarium filter wool) and natural substrata were measured in tidepools and on emergent rock in recently ice-scoured and non-scoured ... -
Physical Conditions of the Gas in an ALMA [CII]-identified Submillimetre Galaxy at z = 4.44
(2013-02-13)We present CO(2-1) observations of the submillimetre galaxy ALESS65.1 performed with the Australia Telescope Compact Array at 42.3 GHz. A previous ALMA study of submillimetre galaxies in the Extended Chandra Deep Field ... -

Physical Volcanology, Petrology, and Petrogenesis of the Cretaceous Isachsen Formation Volcanics, Western Axel Heiberg Island, N.W.T.Formation Volcanics, Western Axel Heiberg Island, N.W.T.
(1994-03-15)New data from Bjarnasson Island and Bals Fiord on western Axel Heiberg Island provide insight into the physical volcanology, petrology, and petrogenesis of Cretaceous Isachsen Formation magmatism. The Bjarnasson Island ... -
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 ... -
