carboniferous strata in the alborz mountains consist of calcareous rich fossils the main part of which is composed of rugose corals. there have been few studies carried out on corals so far. in this paper, a new subfamily, genus and eight new species of rugose corals from mobarak limestones in the central alborz mountains are introduced

Four new species of the subgenus Hoplophorella are desccribed and identified from the Afrotropical region: Atropacarus (Hoplophorella) curtisetosus sp. nov. from Uluguru Mountains of Tanzania, Atropacarus (Hoplophorella) distinctus sp. nov. from Ambohitantely Special Reserve of Madagascar, Atropacarus (Hoplophorella) othneios sp. nov. from Ranomafana National Park of Masagascar, and Atropacarus...

Thirteen fern species are reported for the first time for Brazil. Among the new records, eight are from Acre state (Cyatheasubincisa, Cyclodiumtrianae, Elaphoglossumstenophyllum, Hypoderrisbrauniana, Pleopeltisstolzei, Thelypterisarcana, Thelypteriscomosa, Thelypterisvaldepilosa), two are from Pará state (Polypodiumflagellare, Tectariaheracleifolia), one from Minas Gerais state (Alsophilasalvin...

In "Fractal Mountains," I used recursive subdivision of time, pitch, and amplitude in a fractal algorithm that generates an accompaniment from material played freely on a MIDI wind controller (the "MIDI Horn"). The piece was realized entirely in electronic sound. "Fractal Mountains" won first prize in the international competition for micro tonal music at the 1988 Third Coast New Music Festival...

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 ...
