Incision as a result of fluvial erosion is an important process to model when simulating landform evolution. For gullies, it apparent that coupled with the processes cause incision there must be range stop incision. Once started, rills and gullies will grow infinitely without reduction in support area and/or being arrested by deposition armouring. Some these have been well studied under heading...

The development of a soilless crop culture system based upon the Nutrient Film Technique (NFT) was studied. The conventional polythene gullies used for the NFT in temperate regions were found not ~uitablefor .the ho! tropical -climate. An insulated NFT shallow trough desz~n was effective in controllzng heat buzld up In the root zone. Muskmelon, vegetables and ornamental plants were successfully...

In this study we describe the first apterous species of Endecous Saussure (1878), collected in two caves at Ituaçu, Bahia State, Brazil. In Brazil, Endecous is the most widespread cricket in hypogean environments and its species can colonize caves and inhabit the entrance and the aphotic zones; Endecous species can also be found in the litter, rock gullies, crevices, burrows, and any natural ca...

M easurements of topography can provide a wealth of information on landscape properties fw managing hydrologic and geologic systems and conserving natural and agricultural resources. This article discusses the application of an airborne laser altimeter to measure topography and other landscape surface properties. The airborne laser altimeter makes 4000 measurements per second with a vertical re...

IMPORTANCE Morphometric assessment has emerged as a strong predictor of postoperative morbidity and mortality. However, a gap exists in translating this knowledge to bedside decision making. We introduced a novel measure of patient-centered surgical risk assessment: morphometric age. OBJECTIVE To investigate the relationship between morphometric age and posttransplant survival. DATA SOURCES...

Fires in the ecosystems of Central Kazakhstan trigger a pyrogenic succession for 1-2 decades as usual. In recent years, changes climate and land use region have led to intensification fires gradual steppification territory, where desert vegetation was previously successfully restored. We analyzed change aboveground phytomass stocks during 40 years succession. zonal communities, reaches backgrou...

Data collected in 2012 on 400 chickens were subjected to two-way analyses of variance to estimatebody weight, morphometric traits as well as the correlationbetween body weight and morphometric traitsin Isa Brown and Ilorin ecotypechickens. The studied morphometric traits were comb length, beak length,head length, neck length, body length, wing length, shank length, thigh length, toe length, bre...

We found that craters in the mid-latitudes of Mars possess a marked asymmetry, which is linked with the occurrence of gullies. We also found that a prerequisite for gully formation is the occurrence of steep slopes. The analysis was performed in three areas with elevation data from the High Resolution Stereo Camera (HRSC) on-board Mars Express. Figure 1: MOLA global map with our study sites mar...

Our main goal is to assess the hydrodynamics of turbidity currents and mudflows and their ability to produce morphological features such as ripples, dunes, antidunes and gullies along their paths. Of particular interest is to elucidate the role played by turbidity currents on the inception of submarine channels and canyons. To this end, understanding the mechanics of sediment erosion, including...
