Future Weather Files to Support Climate Resilient Building Design in Vancouver

Belgin Terim Cavka & Malin Ek
Since local weather and climate greatly affect the construction and performance of buildings, reliable meteorological data is essential when simulating building performance. It is well understood that climate change will affect future weather and there is a growing interest in generating future weather files to support climate resilient building design. Weather files that account for climate change have not been widely used for the lower mainland region of British Columbia. In this study, hourly weather...

Chemistry at the porphyrin periphery

Jill MacAlpine
The objective of this work was to synthesize novel aromatic compounds based on tetraphenylporphyrins. These compounds are potential photosensitizers for use in photodynamic therapy. Several approaches were employed towards this goal. Numerous tetraphenylporphyrins possessing a variety of substituents were synthesized, characterized and used as starting materials to prepare the analogous diol chlorins via the patented osmium tetroxide oxidation. Compounds possessing hydroxy, methoxy, alkyl and halogen substituents were prepared. Studies involving the syntheses of these variously...

The Ledge

The oldest mining camp newspaper in British Columbia. ; The Ledge was published in Greenwood, in the Kootenay Boundary region of southern British Columbia. The Ledge was published by James W. Grier until 1907, and was subsequently published by R. T. Lowery (1907-1920) and G. W. A. Smith (1920-1929). The paper's longest-serving editor was R. T. Lowery (1906-1926), a prolific newspaper publisher, editor, and printer who was also widely acclaimed for his skill as a...

Optimal path/neutral [i.e. neural] network approaches to modeling of forest road design for use in automated GIS systems

Ionut Andrei Aron
A model that integrates the use of feed-forward Artificial Neural Networks and GIS techniques was developed for preliminary road design in forestry. The model was built and tested with GIS data from Malcolm Knapp Research Forest (approximately 5000 ha). Artificial Neural Networks having a variety of architectures were trained using this data, in conjunction with a several different learning parameters. Once the neural networks were trained and tested, the knowledge was used to predict based...

Kootenay Mail

The Kootenay Mail was published in Revelstoke, in the Columbia-Shuswap region of southeastern British Columbia, and ran from April 1894 to December 1905. The Mail was published by the Revelstoke Printing and Publishing Company, and its longest-serving editor was J. Livingstone Haig. In 1906, the Mail merged with the Revelstoke Herald to form the Mail-Herald, a staunchly conservative paper that eventually folded due in part to competition from a more liberal competitor, the Revelstoke Review.

Fabrication techniques and RF performances of transmission lines on polymer substrates

Jianqun Wang, Ying Cai, Thermpon Ativanichayaphong, Mu Chiao & J.-C. Chiao
The advantages of polymers have made them popular choices in many micro device applications. The benefits of low material and fabrication costs have been demonstrated in many micro-fluidic devices. The low conductivities and low dielectric constants of polymers provide potentials for high quality-factor RF MEMS applications. Nevertheless, the extension of using polymers for electronic components has not been well explored. In this work, we investigated the fabrication processes and RF performances of coplanar waveguide (CPW)...

Population energetics of two amphipod species in Marion Lake

Jack Anthony Mathias
The population energetics of two species of amphipods was studied at several depths in Marion Lake, BC. Hyalella azteca was abundant at a depth of 1.0 m, (mean summer standing crop, 1952 animals/m2 but became rare (75 animals/m2 at depths greater than 2.5 m. Growth rates, res- piration rates, and hence energy flow were decreased by the lower ambient temperatures of deeper water, On an annual basis, a mean standing crop of 1.1 Kcal/m2 of...

The effects of dietary molybdenum and sulfur on serum copper concentrations, growth and reproductive function in lambs

Julie A. Robinson
Feeds often contain molybdenum (Mo) and sulfur (S) in excess of recommended allowances for adequate copper (Cu) absorption by ruminant livestock. Two randomized-block experiments were conducted using lambs given a cereal-based diet (90% of dry matter (DM) intake), containing 8 mg Cu, 0.7 mg Mo and 2.1g S per kg DM, that was either unsupplemented or supplemented with ammonium molybdate or sodium sulfate alone or in combination, to determine the effects of Mo, S and...

MetaPathways: a modular pipeline for constructing pathway/genome databases from environmental sequence information

Kishori M Konwar, Niels W Hanson, Antoine P Pagé & Steven J Hallam
Background. A central challenge to understanding the ecological and biogeochemical roles of microorganisms in natural and human engineered ecosystems is the reconstruction of metabolic interaction networks from environmental sequence information. The dominant paradigm in metabolic reconstruction is to assign functional annotations using BLAST. Functional annotations are then projected onto symbolic representations of metabolism in the form of KEGG pathways or SEED subsystems. Results Here we present MetaPathways, an open source pipeline for pathway inference that...

Nelson Economist

The Nelson Economist was published in Nelson, in the Central Kootenay region of southeastern British Columbia, and ran from July 1897 to July 1906. The Economist was published by D. M. Carley, and edited by C. Dell-Smith. In August 1898, the Economist absorbed a paper called the Nation. In July 1903, the title of the paper was changed from the Nelson Economist to the Economist.
