The population of engineers is insufficient to meet long-term demand; although immigration is boosting the numbers and adding diversity to the mix, women are still severely underrepresented 1,2. The recruitment of women into these programs is a clear opportunity to meet industry demand for engineers. Young women occupy an increasing percentage of the seats in high school physics classrooms 3,4. This paper presents evidence from the British Columbia school system depicting trends in the number of young women completing high school physics and the careers they choose to pursue. The data is interpreted through a review of the history of feminist influences on education in British Columbia and on Canadian society. © American Society for Engineering Education, 2015. Source

The maximum number of mutually orthogonal latin squares (MOLS) of order 10 is known to be between 2 and 6. A hypothetical set of four MOLS must contain at least one of the types of group divisible designs (GDDs) classified here. The proof is based on a dimension argument modified from work by Dougherty. The argument has recently led to the discovery of a counterexample to Moorhouse's conjecture on the rank of nets, found by Howard and Myrvold. Although it is known that even three MOLS can admit no nontrivial symmetry group, we are hopeful this classification via GDDs and dimension can offer some structure to aid the eventual goal of exhausting the search for four MOLS of order 10. © 2012 Springer Science+Business Media, LLC.

Total wrist arthroplasty for chronic arthritis has become increasingly popular because it provides excellent relief, but its longevity remains unclear. The purpose of this study was to provide an evidence-based summary on implant survivorship, with a focus on mid- to long-term results. First generation implants had a mid-term survivorship of only 42%. Second and third generation implants have had varying results in both midto long-term studies. A long-term registry study of three third generation implants also showed differing results among prostheses. Fourth generation implants have had better durability with survivorship reported to be greater than 90%, but there are only published data for one type of implant. No formal Kaplan-Meier survivorship data have been published for any other type of implant from this generation. Wrist arthroplasty is still an evolving procedure, as current fourth generation implants have shown good mid-term survivorship. Long-term prospective studies of the various implants and their survivorship are still lacking. However, multicenter trials will assist in providing a larger sample size, better methodology, and cost sharing. Copyright © 2015 Wolters Kluwer Health, Inc. All rights reserved. Source

Two of the most common products currently used to control parasitic sea lice in fin fish aquaculture, salmon in particular, are Slice® and AlphaMax®. Emamectin benzoate (EB) is the active ingredient in Slice® and deltamethrin is the active ingredient in AlphaMax®. Several analytical methods have been developed for the determination of the active ingredients in these products but these have been focused on specific matrices and lack the sensitivity and versatility required in environmental monitoring. Here we present a validated, versatile, and simple analytical method for the determination of EB, its desmethyl degradation product (AB), and deltamethrin in a wide range of environmental matrices (sea water, marine sediment, and tissue). Sediments and tissues were extracted by accelerated solvent extraction (ASE®) and sample cleanup was achieved by solid phase extraction (SPE) while sea water was extracted using SPE disks. Analyte identification and quantification was based on liquid chromatography tandem mass spectrometry (LC-MS/MS) instrumentation with electrospray ionization, and multiple reaction monitoring (MRM). Method detection limits for the target analytes was in the parts per trillion (pg g-1) level for tissue and sediment and parts per quadrillion (pg L-1) for water. Except for deltamethrin in sea water, method performance in terms of analyte recoveries was better than 60%, and the method precision was RSD<20%. The method was used to determine EB and AB concentrations in water, sediment and prawn tissue samples collected near salmon aquaculture sites treated with Slice®. A distinct concentration gradient was observed in the immediate vicinity (within 50 to 100 m radius) of the salmon aquaculture sites where EB was detected at low ng g-1 levels for tissue (EB ranged from 0.041 to 3.0 ng g-1) and sediment (EB ranged from 0.051 to 35 ng g-1) and pg L-1 levels (EB ranged from 3 to 209 pg L-1) for water samples. © 2013 Copyright Taylor and Francis Group, LLC.

A series of learning units was developed as a high-interest STEM teaching tool for a group of Aboriginal high school students. The units integrated e-learning, classroom learning and technology in a way designed to spark interest in subject matter, and to help students see links between mathematics and engineering and the real world. The series, entitled "Digital Music Math," culminated in a field trip to the local college to construct an electronic game, and each learning unit was connected in a material way to this final project.
