This paper addresses the long-standing problem of generating fractal mountains with rivers, and presents a partial solution that incorporates a squig-curve model of a river’s course into the midpoint-displacement model for mountains. The method is based on the observation that both models can be expressed by similar context-sensitive rewriting mechanisms. As a result, a mountain landscape with ...

in the view of quran, the standee mountains holding the layers of earth start to move and getting the anxious and exploded and even turn to dust. at the beginning of the doomsday in the researched verses they are simile to tufts of yarn. god in the many verses announced of finality of mountains that they flattened with the earth and scattered about – and like tufts of yarn are pulverized and al...

this study is focused on the biostratigraphy, sedimentary environments, facies distribution, and sequence stratigraphy of the coniacian–santonian sediments of tange-bulfaris section. five assemblage zones have been recognized by distribution of the foraminifera in the study area. assemblage zone 1(chara ostracods zone) is coniacian in age and occurs in the lower part of the succession. assembla...

The present study focused on redescription of Gammarus pseudosyriacus (Karaman & Pinkster, 1977) based on new materials from Zagros Mountains and describes a new subspecies of freshwater amphipod, Gammarus pseudosyriacus issatisi subsp. n., from the southern Zagros Mountains. The work is based on morphological and morphometric comparisons. This new subspecies has features similar to Gammarus ps...

CHITRA is a prototype CBIR system we are building. It uses a four layer data model we have developed, and enables retrieval based on high level concepts, such as \retrieve images of MOUNTAINS", and \retrieve images of MOUNTAINS and SUNSET". This paper deals with some issues about query processing encountered in the implementation of the system. The contributions of this paper can be summarized ...

The exchange of chlorinated organic pollutants between air and vegetation in cold, mountain environments was investigated through the extraction of coniferous vegetation and high-volume air samples collected from the Canadian Rocky Mountains during the summers of 1999 and 2000. Concentrations of several compounds in vegetation increased as temperatures decreased, whereas atmospheric concentrati...

The mid-altitude zone of the Qinling Mountains in China was once dominated by birch and pine-oak belts but are now mainly covered by secondary growth following large-scale deforestation. Assessing the recovery and sustainability of these forests is essential for their management and restoration. We investigated and compared the tree species composition and community assemblages of secondary for...

Evaluating conflicting theories about the influence of mountains on carbon dioxide cycling and climate requires understanding weathering fluxes from tectonically uplifting landscapes. The lack of soil production and weathering rate measurements in Earth's most rapidly uplifting mountains has made it difficult to determine whether weathering rates increase or decline in response to rapid erosion...

Mountains on rapidly rotating neutron stars efficiently radiate gravitational waves. The maximum possible size of these mountains depends on the breaking strain of the neutron star crust. With multimillion ion molecular dynamics simulations of Coulomb solids representing the crust, we show that the breaking strain of pure single crystals is very large and that impurities, defects, and grain bou...
