BACKGROUND It is well established that the work rate increment size affects the duration of test and physiological responses to exercise during cycling in patients with COPD. However, this has never been tested for incremental step tests. OBJECTIVE To compare the exercise tolerance time, cardiopulmonary stress, and perception of effort between the Chester step test (CST) and a modified incre...

The Scientific Teaching (ST) pedagogical framework provides various approaches for science instructors to teach in a way that more closely emulates how science is practiced by actively and inclusively engaging students in their own learning and by making instructional decisions based on student performance data. Fully understanding the impact of ST requires having mechanisms to quantify its imp...

Mist cooling has been considered as a potential means to significantly enhance cooling the hot components of a gas turbine. However, it is a great challenge to transport mist to locations where cooling is needed due to the high temperature environment and rotating components in the gas turbines. One plausible way is to transport high-pressure water to the rotor cover-plate cavity via a feed cha...

The aim of this study was to compare the effects of nebulized mist and liquid drop applications on retrobulbar blood flow. A prospective, non-randomized clinical trial was used to collect data from 40 healthy human eyes. Color Doppler Imaging determined peak systolic (PSV) and end diastolic (EDV) blood flow velocities and resistance index (RI) in the ophthalmic artery after both applications. M...

This paper describes a building/environment data and information system, called BeDIS for short. It is designed to support fine-scale, location specific services by smart devices and mobile applications for people in large smart buildings. Structured as a fog/mist, the system is scalable and responsive under overload; can function without Internet, WiFi and cell connections; and degrades gracef...

Reactive gaseous Hg (RGHg), usually assumed to be HgCl2, may dominate the total Hg depositional flux due to its higher surface reactivity and water solubility. Three methods are currently used for RGHg sampling: multistage filter packs, refluxing mist chambers, and KCI-coated denuders, but none of these methods are considered standard. Field comparisons were performed at Chesapeake Biological L...

This study aimed to identify vulnerability patterns in psychological, physiological and neural responses to mild psychosocial challenge in a population that is at a direct risk of developing depression, but who has not as yet succumbed to the full clinical syndrome. A group of healthy and a group of subclinically depressed participants underwent a modified Montreal Imaging Stress task (MIST), a...

Recording the activity of large populations of neurons requires new methods to analyze and use the large volumes of time series data thus created. Fast and clear methods for finding functional connectivity are an important step toward the goal of understanding neural processing. This problem presents itself readily in somatosensory neuroprosthesis (SSNP) research, which uses microstimulation (M...

Air film cooling has been widely employed to cool gas turbine hot components such as combustor liners, combustor transition pieces, turbine vanes and blades. Enhancing air film cooling by injecting mist with tiny water droplets with diameters of 5-10μm has been studied in the past on flat surfaces. This paper focuses on computationally investigating the curvature effect on mist/air film cooling...
