A canister-based sampling method along with preconcentrator-Gas chromatography-Mass Spectrometry (GC-MS) analysis was applied to ethylene oxide (EtO or EO) and 75 other volatile organic compounds (VOCs) in ambient air. Ambient air can contain a large variety of VOCs, thorough requires non-discriminatory chromatographic capable resolving complex mixture. Canister collection whole samples allows ...

The authors present a case of unusual rise in inspired carbon dioxide due to misplaced absorbent canister.

The British Columbia Geological Survey Branch and the Geological Survey of Canada have initiated ajoint project to assess the coalbed-methane potential of coal deposits in British Columbia. This project entails participation with private industry to obtain fresh coal samples for desorption from exploration projects throughout the province. Samples are collected from the drill site and undergo a...

Description of Lesson: In this lesson students experiment with force and motion using a " Newton Car " (adapted from NASA) to explore the effects of mass and force on acceleration. Student Objectives: The students will be able to create a testable question and hypothesis, run a fair test, measure distance for data, and make a conclusion using the data. Students will be able to identify the affe...

Background: The metered-dose inhalers (MDIs) currently available for inhaled corticosteroid delivery do not offer an integrated dose counter; therefore, it is difficult to evaluate adherence of patients. The present authors developed a linear regression equation using canister weight to calculate the number of doses actuated from the MDIs. This study aimed to assess medical adherence after the ...

A two-dimensional computational model of a loaded used nuclear fuel canister filled with helium gas was constructed to predict the cladding temperature during vacuum drying conditions. It includes distinct regions for the fuel pellets, cladding and helium within each basket opening. Symmetry boundary conditions are employed so that only one-eighth of the package cross-section is included, and t...

This study investigates the dissolution, sorption, leachability, and plant uptake of tungsten and alloying metals from canister round munitions in the presence of model, well characterized soils. The source of tungsten was canister round munitions, composed mainly of tungsten (95%) with iron and nickel making up the remaining fraction. Three soils were chosen for the lysimeter studies while fou...

A statistical test is proposed for in vitro bioequivalence testing between drug products such as nasal aerosols and nasal sprays. The proposed test generalizes the one recommended in the FDA 1999 guidance to the situation where replicated observations obtained from each sampled canister or bottle of the drug product are available. The technique developed by Hyslop, Hsuan and Holder is used so t...
