Practical aspects on the estimation of the parameters in Coale's model for marital fertility
Estimation ; Fécondité légitime ; Généralités sur la géographie ; Loi de Poisson ; Maximum de vraisemblance ; Modèle de Coale ; Population ; Statistique
Le modèle proposé par Coale en 1971 s'applique moins bien aux populations à effectif réduit. L'A. propose de tenir compte de ces biais en proposant une estimation basée sur la méthode du maximum de vraisemblance, sous l'hypothèse d'une simple loi de
K zahajeni prepravy energetického uhli po Labi do Chvaletic Transport of coal by the Labe waterway and its importance for the development of water-transport in Czechoslovakia
The Labe waterway is increasingly used as a result of water transport of coal to the power plant at Chvaletice. Further power plants will be supplied by means of waterway in the near future. So the transport of coal for power plants has promoted

Zusammenhänge zwischen geologischem Untergrund und Flozbildung am Beispiel der Braunkohlenlagerstätte Wallendorf. (Connections between geologic underground and formation of seams at the exemple of the Wallendorf brown-coal deposit)
results of the main prospection work led to essential conclusions on the interrelations between the geologic underground formation of seams and coal qualities. Thus it became possible to find out possible areas of brine-breakthrough, to explain deposit
and coal anomalies, to tell about briquetting properties and to take measures of coal utilization and future prospection and research tasks. (HL).
Bergbaubedingte Veränderungen des physischen Nutzungspotentials dargestellt am Beispiel des linksrheinischen Braunkohlreviers. (Changes of the natural potential resulting from mining on the example of the Rhenish Brown Coal Field)
The purpose of the study is to analyse the changes resulting from the mining of brown coal. The study examines the natural potential of the sample areas before the extraction of the brown coal and after the recultivation, and it evaluates
of suitability for the various forms of land use before the mining and after the recultivation. The following comparison of the original land potential before coal mining with the final land potential after recultivation permits to determine improvements

Within-storm variations in runoff and sediment export from a rapidly eroding coal-refuse deposit
This study presents sedimentologic and hydrologic data collected from an ephemeral gully on a rapidly eroding coal-refuse deposit in south-western Indiana during three storms, and provides evidence that production of coarse sediment increases non
