In solving the engineering problems in practice of different specialties, design roads and roads, structures, determining physiographic conditions same regional areas: basin area (F), height (Z), average square difference (s), slope (J), parameters such as length main channel (L), width maximum water flow (V) its depth (h), that is determination calculated values morphological indicators, perfo...

The Ellenburger Group of the West Texas Permian Basin is part of a Lower Ordovician carbonate platform sequence that covers a large area of the United States. During the Early Ordovician, the Permian Basin area was located on the southwest edge of the Laurentia plate between 20° and 30° latitude. The equator crossed northern Canada, situating Texas in a tropical to subtropical latitude. The are...

The state of conservation of Atlantic Forest in the Maquiné river basin was assessed using land cover data obtained from Landsat TM 5 satellite imagery (October 1995). The initial analysis examined the distribution of the relative areas of each land-cover type according to landscape slope classes, potential vegetation zones, and a 90 m riparian buffer. Land-cover classes were then regrouped int...

Mesacanthus is a common and speciose genus of acanthodian fish from Lower Old Red Sandstone and Middle Old Red Sandstone assemblages (representing the Lower Devonian and Middle Devonian respectively) and is well represented in many palaeoichthyology collections in the UK. Based upon descriptions given during the 19th century, specimens of the genus Mesacanthus from the Orcadian Basin and Midlan...

Since the pioneering work of McGeer in the late 1980s, the concept of passive dynamic walking (hereafter PDW) has been attracting lots of attention in the field of legged robots 1) A significant feature of PDW robots is that they have no control system; they merely exploit their intrinsic mechanical dynamics carefully designed, and show surprisingly natural and human-like walking on a gentle sl...

Background and objectives The primary objective of drilling at Site U1345 was to study high-resolution HoloceneLate Pleistocene paleoceanography at a proximal gateway location to the Arctic Ocean at a water depth of ~1008 m. The drill site is located on an interfluve ridge near the large and broad head of Navarin Submarine Channel off the Bering Sea Shelf. It is anticipated to receive ample sup...

since direct experimental evidence is not available, this must be verified through a modeling approach, providedadequate data be available. many statistical methods are used to study the relation between independent anddependent variables.this research was carried out at the western part of jazmurian basin tlocated in the southeast ofiran. in this paperused ten physical characteristics such as ...

Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract Dissolved organic carbon (DOC) and total dissolved amino acids (TDAA) were measured in high (Chukchi Sea) and low (Beaufort Sea) productivity regions of the Western Arctic Ocean to investigate the composition an...
