    A sample translatory type insert for automated magnetocaloric effect measurements (1997)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 68 (1997), S. 1818-1822 
    Details
    ISSN: 1089-7623
    Source: AIP Digital Archive
    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: This paper describes the development of an automated sample translatory type apparatus capable of measuring the magnetocaloric effect of potential magnetic refrigerants over the temperature range 10 to 325 K in applied fields of up to 9 T. A Quantum Design® Physical Property Measurement System has been used as the host platform. The emphasis of the design is on rapid and accurate automated measurements with field slew rates of 9 T per second. Measurement repeatabilities of ±30 mK have been achieved. Results are presented for the rare earth metals gadolinium, dysprosium and holmium, and a gadolinium-yttrium alloy. © 1997 American Institute of Physics.

    Effect of sample preparation on the magnetic and magnetocaloric properties of amorphous Gd70Ni30 (1998)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 83 (1998), S. 2727-2734 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Certain applications of magnetic materials require the knowledge of the magnetocaloric effects, i.e., the adiabatic change of temperature or the isothermal change of the entropy upon application or removal of magnetic field. While the isothermal magnetic entropy change can be calculated from magnetic data only, the calculation of the adiabatic temperature change requires the knowledge of the field-dependent specific heat as well. To compare magnetocaloric effect results obtained from magnetic-only, thermal-only, or combined methods requires the evaluation of the mutual reliability of all methods. In crystalline materials it usually does not present a problem to perform thermal and magnetic measurements on the same sample or at least on samples of identical state. For amorphous materials, unfortunately, thermal measurements are extremely difficult to perform on the ribbons themselves so usually pellets pressed from powdered ribbons, with silver as a binder, are applied. After the magnetic entropy change calculated from thermal measurements performed on such a composite did not agree with the data obtained from magnetic measurements performed on the original ribbon, magnetic measurements were carried out on the pellet and its predecessor powders. Comparison of the results revealed that the pellet's properties do not reflect the properties of the original ribbon. However, comparison of magnetic and thermal measurements carried out on the pellet itself show good agreement if proper numerical methods are used for evaluation. The study concludes that amorphous ribbons are far more competitive for certain applications than the thermal measurements, performed on the pellet only, would indicate. © 1998 American Institute of Physics.

    Noncontact thermoacoustic method to measure the magnetocaloric effect (1995)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 66 (1995), S. 232-238 
    Details
    ISSN: 1089-7623
    Source: AIP Digital Archive
    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: We report here the measurement of the magnetocaloric effect in a magnetic material with the use of noncontact type detection. The technique is based on the thermoacoustic principle. A sample with a periodically changing surface temperature induces exponentially decaying pressure waves which can be detected by a sensitive microphone. A magnetic material placed within a gas-tight cell at an appropriate dc magnetic field and temperature will exhibit a periodically changing surface temperature due to the magnetocaloric effect when subjected to a small ac field superimposed over the dc field. The microphone response, detected via a lock-in amplifier can be correlated to the magnitude of the temperature changes after suitable calibration. The knowledge of the magnetic equation of state allows the determination of the total magnetocaloric effect ΔT for an arbitrary field step from zero to the final value, using the magnetization data of the sample as well. Gadolinium has been used for calibration, and new results are presented for a gadolinium-dysprosium and a gadolinium-erbium alloy. © 1995 American Institute of Physics.

    Issues in the Conservation and Management of Forests in Laos: The Case of Sangthong District (1998)
    Oxford, UK and Boston, USA : Blackwell Publishers Ltd
    Singapore journal of tropical geography 19 (1998), S. 0 
    Details
    ISSN: 1467-9493
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geography
    Notes: Amidst the increasing concern about steadily depleting forests in Laos, this paper examines its causes and existing forest management systems in Sangthong District. Forests in Sangthong were virtually undisturbed until the early 1970s. Guided by customary law, a relatively small local population utilised the forest sustainably for food, fodder, wood fuel and construction materials. Subsequently the government effectively abolished customary law through the declaration of forests as state property and the sanctioning of logging. Logging was banned in the early 1990s but forest degradation continues as a result of ongoing logging, the open access to forests, the government policy of utilising degraded forests for agriculture, and population pressure from in-migration. Village surveys show that local people appreciate ecological and economic values of forest resources and are willing to contribute to their management. These social qualities lay the foundation of a sustainable forest management system, but the evolution of this type of system has been prevented by the “open access” to forest resources. For effective forest conservation a management strategy focused on property rights reform, public participation and integrated rural development is proposed.
