Verification of a simple gravity technique for separation of particle size fractions suitable for mineral magnetic analysis
Techniques for the separation of sediment samples into size fractions are reviewed and the use of repeated decantations to provide samples for mineral magnetic analysis is described. Results from a series of trials are presented and compared
Characteristics of post-separation families in the Netherlands : shared residence versus resident mother arrangements
The AA. use an explanatory mixed methods research design to enhance insight into the life course characteristics of separated parents involved in shared residence arrangements. Survey data derived from panel study and divorce are supplemented
with information from in-depth interviews. Shared residence parents seem to be a typical modern category of separated parents with a specific set of characteristics.
Argument in favor of segregating human geography from physical geography, and considering each as a separate discipline. The A. asserts that such a separation would make human geography a legitimate social science. - (DWG)
Isotope hydrograph separations and rapid delivery of pre-event water from drainage basins
Environmental isotopes, such as oxygen-18 and deuterium, have been used increasingly to separate stormflow into its event and pre-event components in order to elucidate the sources, pathways and residence times of water in drainage basins
. The hydrological processes that have been invoked to explain the observed isotopic response of streamflow to rainfall and snowmelt inputs in various environments are reviewed. This paper summarizes the environmental isotope hydrograph separation technique
and provides a broad review of the results of isotope hydrograph separations conducted around the world.
A spreadsheet-based technique (Lotus 1-2-3) for separating tropical forest storm hydrographs using Hewlett and Hibbert's slope
The inclined line separation technique of Hewlett and Hibbert has been widely adopted to separate delayed flow from the total stream storm runoff. Presented here is the application of the technique to highly responsive storm hydrographs using
a personal computer method based on a Lotus 1-2-3 spreadsheet. Separation of flow by computer spreadsheet methods may be consistently applied throughout a dataset and therefore have a comparative advantage over more arbitrary techniques.
The use of laboratory spectroscopy to establish Pteronia incana spectral trends and separation from bare surfaces and green vegetation
The spectral trends of Pteronia incana, an unpalatable invader shrub, and its separation from bare surface and green vegetation are examined using a high resolution spectrometer. A consistent spectral trend showing a clear distinction between
Nonsecessionist regionalism in India : the Uttarakhand separate State movement
The A. examines the recent mass movement for a separate state of Uttarakhand, an area which currently forms the Himalayan part of the State of Uttar Pradesh. He concentrates on one aspect of the movement, namely how protestors have mobilised
Beiträge des Geographiemethodikers Alfred Hettner zur Konstituierung der Kartographie als selbständige Wissenschaftsdisziplin. (Contributions of Alfred Hettner, geographical methodologist, to the constituent development of cartography as a separate
Cartography as a scientific separate discipline developed from geography and geodesy. At first Alfred Hettner, scientist of geography-methodics, should be mentioned among the geographers who played an important role therein. His activities
The separation of hydrological periods and description of river regimes by comparison of probability distribution of water stages by pentads
of the river regime investigations as well as the basis for its characteristics. 0n the example of the Prosna river were presented the usefulness of the described theoretical model and the methods for the separation of those periods in order to investigate
Residual relief separation : digital elevation model enhancement for geomorphological mapping
This paper proposes a technique, residual relief separation, to enhance landforms in DEMs prior to visualization and digital mapping. This is applied to a 600km2 region surrounding Lough Gara, Ireland, where drumlins overlie a regional relief
of hills. Here, residual relief separation uses this difference in width-scale. Finally, vizualisation uses a simple black-to-white colour scale for height. This research demonstrates the use of width-scale parameters to enhance landscape visualization.
