This paper describes work aimed at developing a practical shape-from-shading process for terrain analysis from radar imagery. The paper commences by providing an analysis of the radar reflectance properties of terrain structures. By using ground truth elevation data, we provide an empirical study of the radar reflectance characteristics for large-scale terrain features. The main conclusion of t...

The present study provides data on the trophic structure of benthic macroinvertebrate communities in mountainous and semi-mountainous small streams river sections belonging to Mesta, Struma Vardar River catchments from 7th Ecoregion. macroinvertebrates were assigned seven Functional Feeding Groups. We analyzed their dynamics different seasons. level similarity between sampling localities was co...

Rainfall is a spatiotemporally varied process and key to accurately capturing catchment runoff determining flood response. Flash response of can be strongly governed by rainfall’s spatiotemporal variability influenced storm movement which drives continuous change throughout rainfall event. In this work, the sensitivity flooded areas are assessed in Kan (Iran). The allochthonous nature floods ho...

While deforestation is a major environmental issue in the tropics, with thousands of hectares converted to agricultural land every year, Europe opposite trend observed, abandonment mountainous and semi-mountainous areas allowing afforestation former pastoral land. This allows semi-natural ecosystems recover after prolonged period exploitation often over-exploitation, but it may also lead signif...

biodiversity is an important component in sustainability assessment of agroecosystems. along with increasing or decreasing of biodiversity, ecosystem services in agroecosystems will be varied. agricultural experts take into account different factors which affect agroecosystems variation. in this study, farming systems of two areas including a protected mountainous area and also a plain – hilly ...

The aim of this study was to test whether there is an association between elevation and cognitive function among elderly residents in rural mountainous areas. Data were collected in 2012 from a cross-sectional study conducted in Ohnan Town, which is located in a rural mountainous area in the southern part of Shimane Prefecture, Japan. Cognitive function was evaluated using CADi (Cognitive Asses...

DESIGN AND SETTING Prospective study, based on the adult population of two lowland and one mountainous village in rural Greece. Baseline measurements on sociodemographic, lifestyle, somatometric, clinical, and biochemical variab...
