    The initial analysis of the ERTS-1 multispectral scanner (MSS) data at the Johnson Space Center (JSC), Houston, Texas is discussed. The primary data set utilized was the scene over Monterey Bay, California, on July 25, 1972, NASA ERTS ID No. 1002-18134. It was submitted to both computerized and image interpretative processing. An area in the San Joaquin Valley was submitted to an intensive evaluation of the ability of the data to (1) discriminate between crop types and (2) to provide a reasonably accurate area measurement of agricultural features of interest. The results indicate that the ERTS-1 MSS data is capable of providing the identifications and area extent of agricultural lands and field crop types

    Three study areas supporting the U.S./Canada Wheat and Barley Exploratory Experiment are discussed including an evaluation of the experiment shakedown test analyst labeling results, an evaluation of the crop proportion estimate procedure 1A component, and the evaluation of spring wheat and barley crop calendar models for the 1979 crop year

    C-GLOVES: An evaluation of the effectiveness of compression gloves in arthritis: a feasibility study : Hand assessment manual and glove treatment protocol 13.8.13v2

    Get PDF
    The C-Gloves compression glove feasibility study evaluated the effects of compression gloves on hand pain, stiffness, joint swelling, finger flexion, grip ability, grip strength and hand function. This manual includes the: inclusion/ exclusion criteria; glove treatment protocol; glove instruction sheet for patients; and protocols for conducting all assessments. These included: hand joint circumference (wrist, MCPs and PIP joints) using a Jobskin® tape measure; finger flexion measured using a 15cm ruler from the lateral nail fold to distal wrist crease (2nd=5th digits); and the Grip Ability Test (GAT). The latter was adapted for the right and left hands and the test procedure further standardised, including the use of the GAT MAT. The GAT MAT template is also located in the www.usir.salford.ac.uk depository and can be freely download

    Multimodality Imaging in Ischemic Cardiomyopathy.

    Get PDF
    Cardiac multimodality (hybrid) imaging can be obtained from a variety of techniques, such as nuclear medicine with single photon emission computed tomography (SPECT) and positron emission tomography (PET), or radiology with multislice computed tomography (CT), magnetic resonance (MR) and echography. They are typically combined in a side-by-side or fusion mode in order to provide functional and morphological data to better characterise coronary artery disease, with more proven efficacy than when used separately. The gained information is then used to guide revascularisation procedures. We present an up-to-date comprehensive overview of multimodality imaging already in clinical use, as well as a combination of techniques with promising or developing applications

    Rotation of Coulomb crystals in a magnetized inductively coupled complex plasma

    Get PDF
    Under suitable conditions, micron-sized dust particles introduced into inductively coupled argon plasma form a stable microscopic crystal lattice, known as a Coulomb (or plasma) crystal. In the experiment described, an external axial magnetic field was applied to various configurations of Coulomb crystal, including small crystal lattices consisting of one to several particles, and large crystal lattices with many hundreds of particles. The crystals were observed to rotate collectively under the influence of the magnetic field. This paper describes the experimental procedures and the preliminary results of this investigation
