The roles of texture and structure in the water retention capacity of burnt Mediterranean soils with varying rainfall
The objective of this work was to evaluate whether different soil conditions at burnt sites result from fire or from different climatic conditions (average annual precipitation). For this purpose, an altitudinal transect affected by forest fires
was chosen. Along the transect, 4 sites, with different amount of annual rainfall, but with almost homogeneous soil parent material, soil type and vegetation, were selected.
This paper reports AMS C 14 ages of 10 bones and teeth of 3 species of large mammals from the Dutchess Quarry Caves, New York. Together with the Holocene conventional C 14 dates of charcoal and the varied stratigraphic proveniences of the fluted

of varying temporal extent from willingness to pay per annum to WTP per visit; and the consequences of varying the order in which such questions are presented to respondents.
La pluviométrie moyenne annuelle varie entre 1200 et 3000 mm, avec des régimes bimodaux. Les années 1951-1970 sont caractérisées par une alternance d'anomalies positives et négatives, alors que les années 1971-1990 sont surtout déficitaires. - (JPB)
Using maps and regression analysis, the AA. sort out the varying turnout rates in elections across the 330 municipalities of Guatemala. An unexpected finding is that turnout covaries with the share of the population that is indigenous
The paper reports on an enquiry into the provision of health care facilities in rural northern KwaZulu-Natal. It concludes that there are more varied types of health facilities available for community members than those conventionally found in urban
varies within an area and between areas. Impacts are considerably greater when roads provide communities with access to a major urban centre compared with a small town.
Focusing on enterprise-state relations, the AA. investigate governmental involvement in corporate bodies, soft budgets, subsidies, state purchases, lobbying, and dispute resolution, and present evidence on how such relations vary with ownership
The levels of spatial interactions with certain types of public services, such as libraries and recreation facilities, may vary with the total numbers of opportunities available. Two partially constrained gravity models are developed that provide
Settlements started near the main rivers before World War I and accelerated with Group Settlements of the 1920s. However many Group settlers abandoned their land before 1940. The rate of persistence of families on each block varied considerably
Bankfull discharge was identified in some 30 gravel-bed rivers representing in total c. 40 gauging stations. The catchment sizes vary from 4km2 to nearly 2700 km2. Bankfull discharge value increases with basin size. The selected rivers are spread
Etude géomorphologique des avant-dunes des Iles de la Madeleine. Mise en évidence de 4 types et évaluation du taux moyen de recul. La morphologie des dunes varie notablement entre les côtes occidentale et orientale des îles, reflétant les
Circulation d'ENE bien organisée dans les basses couches (avec un jet nocturne), mal définie en altitude où la force du vent s'atténue tandis que sa direction varie beaucoup. Prédominance de la subsidence, avec une vitesse verticale moyenne de 10 cm

plate-forme sibérienne où la valeur de l'érosion karstique varie de 20 à 50 mm/1000 ans ; la seconde comprend la rive sud du lac Baïkal, le Hamar-Daban oriental, les vallées de Pohabiha, Bezymânka, Slûdânka où le maximum de l'érosion karstique est de
of the watershed reflecting the effect of non-varying parameters (size of the watershed, lithology, relief and tectonics), and to evaluate the effect of varying parameters (climate, vegetation and human-induced deforestation) on the sediment yield values for each
In this study, erosion and sediment characteristics were measured in simulated rainfall experiments for 3 forest soils of contrasting physical properties. 4 erosion treatments combined varying slope and kinetic energy of rainfall to provide 3
Les flux migratoires sont censés varier en sens inverse de la mesure symétrique des coûts migratoires et dans le même sens que la mesure de l'attractivité dépendante de la population. Unicité et propriétés de stabilité des états continus du

as thermal sensations in subjects during varying cloud cover. Preliminary results show clear relationships between DHE as well as Tsk and intensity of solar radiation (Kglob). In fluctuated cloud cover significant changes of DHE, Tsk and thermal sensations
; deflation-moderating impact of irrigation varied in extent with 27 different soil samples. The experiments are capable of providing useful data for the initial stage of form development in wind-blown sand areas, as well.
