An open-source, automated, gas sampling peripheral for laboratory incubation experiments using cavity ring-down spectroscopy.

Spectroscopic instruments are becoming increasingly popular for measuring the isotopic composition and fluxes of a wide variety of gases in both field and laboratory experiments. The popularity of these instruments has created a need for automated multiplexers compatible with the equipment. While there are several such peripherals commercially available, they are currently limited to only a small number of samples (≤16), which is insufficient for some studies.

Feasibility of an Electromyography-Triggered Hand Robot for People After Chronic Stroke.

Importance: Effective treatment of the affected hand after stroke is crucial for improved functional independence and recovery.

Objective: To determine the feasibility and clinical utility of an electromyography-triggered hand robot.

Design: Single-group repeated-measures design.

Methane emissions from abandoned coal and oil and gas developments in New Brunswick and Nova Scotia.

Energy reserves have been exploited in the Atlantic Canadian provinces since the early 1600s, and many fossil fuel extraction sites have been abandoned over this long history of energy development. Oil, natural gas, and coal extraction sites are a source of greenhouse gas emissions, particularly for methane (CH). In this study, we used multiple sampling methods to measure CH from abandoned coal mine openings in Nova Scotia and a legacy oilfield in New Brunswick.

Ultrasound measures of muscle thickness may be superior to strength testing in adults with knee osteoarthritis: a cross-sectional study.

Background: Evaluation of muscle strength as performed routinely with a dynamometer may be limited by important factors such as pain during muscle contraction. Few studies have compared formal strength testing with ultrasound to measure muscle bulk in adults with knee osteoarthritis (OA).

Methods: We investigated the muscle bulk of lower limb muscles in adults with knee OA using quantitative ultrasound.
