    Requirements of time management tools for outpatient physiotherapy practice

    The effects of electronic appointment booking systems on the time management activities of health professionals have received little attention to date. We report on time management practices in three outpatient physiotherapy departments with different paper and electronic systems. The study has identified a set of time management activities and associated social behaviours common to physiotherapy departments. The convenience, flexibility and expressive nature of paper diary systems is of significant value to users, whilst the clarity and superior database functionality of electronic systems are valued by staff using this medium. The study highlights several potential barriers to the effective deployment of electronic booking systems in physiotherapy departments, including poor resource and training provision, concerns regarding restrictive diary control measures, the continued reliance on burdensome duplication procedures and the need to coordinate multiple information artefacts, which need to be addressed if such technology is to be successfully designed and deployed.

    Spatial oscillations in the spontaneous emission rate of an atom inside a metallic wedge

    Full text link
    A method of images is applied to study the spontaneous emission of an atom inside a metallic wedge with an opening angle of π/N\pi/N, where N is an arbitrary positive integer. We show the method of images gives a rate formula consistent with that from Quantum Electrodynamics. Using the method of images, we show the correspondence between the oscillations in the spontaneous emission rate and the closed-orbits of emitted photon going away and returning to the atom inside the wedge. The closed-orbits can be readily constructed using the method of images and they are also extracted from the spontaneous emission rate.Comment: 8 figure

    Autonomous support for microorganism research in space

    Get PDF
    A preliminary design for performing on orbit, autonomous research on microorganisms and cultured cells/tissues is presented. An understanding of gravity and its effects on cells is crucial for space exploration as well as for terrestrial applications. The payload is designed to be compatible with the Commercial Experiment Transporter (COMET) launch vehicle, an orbiter middeck locker interface, and with Space Station Freedom. Uplink/downlink capabilities and sample return through controlled reentry are available for all carriers. Autonomous testing activities are preprogrammed with in-flight reprogrammability. Sensors for monitoring temperature, pH, light, gravity levels, vibrations, and radiation are provided for environmental regulation and experimental data collection. Additional experimental data acquisition includes optical density measurement, microscopy, video, and film photography. On-board full data storage capabilities are provided. A fluid transfer mechanism is utilized for inoculation, sampling, and nutrient replenishment of experiment cultures. In addition to payload design, representative experiments were developed to ensure scientific objectives remained compatible with hardware capabilities. The project is defined to provide biological data pertinent to extended duration crewed space flight including crew health issues and development of a Controlled Ecological Life Support System (CELSS). In addition, opportunities are opened for investigations leading to commercial applications of space, such as pharmaceutical development, modeling of terrestrial diseases, and material processing

    MECHANICAL VARIABLES OF JUMPING DURING NAVAL ACADEMY OBSTACLE COURSE TRAINING ACTIVITIES

    Introduction•-The use of the obstacle course (O-course) activities at the U.S. Naval Academy is mandatory for all midshipmen. To reduce injuries on the 0course, research has been conducted to evaluate other methods related to specific work assignments. The purpose of this study was to determine which variables contributed to the successful jump used in jumping to clear a shelf. METHODS -Five males (age: 20.2 yrs ±1.3; hgt: 178.6 cm± 3,7; wgt: 77.4 kg±7.7) and five females (age: 20.0 yrs ±1.9; hgt: 170.64 cm±7.3; wgt: 63.8 kg ± 8.5) served as subjects. Anthropometric, strength, and video data were collected at the U.S. Naval Academy, Annapolis MD. Three-dimensional video images were collected from the sagittal and posterior views as subjects scaled a shelf. Fifteen data points were digitized, files transformed, data smoothed with a digital filter set at 10Hz and graphed with the Ariel Performance Analysis System (APAS). RESULTS -Statistical differences using two-sample t-tests were found between males and females in the variables: hgt (t=2.193); wgt (t=2.639); percent body fat (t=5.028); leg length (t=2.128); knee flexion peak torque % BW(t=4.459); knee extension peak % BW (t=2.128); knee flexion (t=1.937); and hip extension (t=3.207). All subjects cleared the shelf. However, several subjects used additional time to complete the skilI. Because differences were noted in anthropometric, strength, and kinematic variables, the skill of jumping to c1eartheshelfseemsto favor the taller, stronger individuals. CONCLUSIONS -Because the Navy is incorporating gender neutral standards into their physical training standards, the 0course may not be the most appropriate way of measuring these standards

    Observed Effects of a Changing Step-Edge Density on Thin-Film Growth Dynamics

    Full text link
    We grew SrTiO3 on SrTiO3 [001] by pulsed laser deposition, while observing x-ray diffraction at the (0 0 .5) position. The drop dI in the x-ray intensity following a laser pulse contains information about plume-surface interactions. Kinematic theory predicts dI/I = -4sigma(1-sigma), so that dI/I depends only on the amount of deposited material sigma. In contrast, we observed experimentally that |dI/I| < 4sigma(1-sigma), and that dI/I depends on the phase of x-ray growth oscillations. The combined results suggest a fast smoothing mechanism that depends on surface step-edge density.Comment: 4 figure

    Rainbows in the Grass. II. Arbitrary Diagonal Incidence

    Get PDF
    We consider external reflection rainbow caustic,,; due to the reflection of light from a pendant droplet where the light rays are at an arbitrary angle with respect to the horizontal. We compare this theory to observation of glare spots from, pendant drops on grass; we also consider the potential application of this theory to the determination of liquid surface tension.

    Rainbows in the Grass. I. External Reflection Rainbows from Pendant Droplets

    Get PDF
    In the mid-morning on a sunny day one can sometimes see glare spots associated with uncolored rainbow (i.e., fold) caustics due to the sunlight reflected from the surface of dew or guttation drops. We show that these dewdrop reflection rainbows are due to places on the droplet (i.e., from an inflection circle ) where its Gaussian curvature becomes zero. We work out the theory of such caustics with horizontally incident light and present a comparison of the theory to measurements made in the laboratory. (C) 2008 Optical Society of Americ

    X-ray scattering from surfaces: discrete and continuous components of roughness

    Full text link
    Incoherent surface scattering yields a statistical description of the surface, due to the ensemble averaging over many independently sampled volumes. Depending on the state of the surface and direction of the scattering vector relative to the surface normal, the height distribution is discrete, continuous, or a combination of the two. We present a treatment for the influence of multimodal surface height distributions on Crystal Truncation Rod scattering. The effects of a multimodal height distribution are especially evident during in situ monitoring of layer-by-layer thin-film growth via Pulsed Laser Deposition. We model the total height distribution as a convolution of discrete and continuous components, resulting in a broadly applicable parameterization of surface roughness which can be applied to other scattering probes, such as electrons and neutrons. Convolution of such distributions could potentially be applied to interface or chemical scattering. Here we find that this analysis describes accurately our experimental studies of SrTiO3 annealing and homoepitaxial growth.Comment: 15 pages, 7 figure
