A laboratory soil column experiment was first conducted to analyze water movement in latosol of sugarcane field under drip irrigation from single-point source at different emitter discharge rates. Next, a mathematical model of soil water movement under drip irrigation from single-point source was built using Hydrus-3D, which could accurately simulate the shape of the wetted soil volume and the ...

The unusual behaviour of smectites, their ability to change volume when wetted (swelling) or dried (shrinking), makes soil rich in smectites very unstable and dangerous for the building industry due to possible or likely movement of building foundations and poor slope stability. These macroscopic properties are dominated by the structural arrangement of smectites finest fraction. Here, we show ...

Abstract Hippocampal changes in epilepsy may manifest as hippocampal atrophy/sclerosis. A recent human study suggests that the demonstration of volume loss is more reliable using quantitative evaluation methods. The aim present was to obtain volumetric data both epileptic and healthy dogs, compare volumes groups, subjective assessment. Volumetric measurements hippocampi, lateral ventricles hemi...

the variety of sprinkler devices available for the center pivot and linear irrigation systems has been increased dramatically in recent years. in the current study, via conducting some indoor experiments, one type of fixed pad spray sprinkler (d3000) and two types of moving pad spray sprinklers (r3000 and s3000) with various configurations (working pressure, nozzle size and type of deflector pa...

This study examined activation levels in the left (L) supplementary motor area (SMA) and the right (R) SMA (separately), and activation in nine R perisylvian language homologues during overt, propositional speech in chronic nonfluent aphasia patients. Previous functional imaging studies with a variety of chronic aphasia patients have reported activation in these regions during different languag...

The subject of the investigation was the influence of pre-wetted lightweight aggregate on damage of the concrete surface due to cyclic freezing and thawing in the presence of de-icing salts tested according to the Swedish Standard SS 13 72 44 (the Borås method). Six series of concrete specimens were made with the same water/binder (w/b) ratio 0.32, cement volume 400 kg/m and content of superpla...

The effect of intravenous infusion of 10 per cent glycerol on regional cerebral blood flow (using hydrogen bolus and Xenon-133 (133Xe) clearance methods) and metabolism was investigated in 57 patients with recent cerebral infarction. Hemispheric blood flow (HBF) increased, together with increase in regional cerebral blood flow (rCBF) and cerebral blood volume (rCBV), in foci of brain ischemia. ...

The effect of intravenous infusion of 10% glycerol on regional cerebral blood flow (using hydrogen bolus and Xenon-133 ['33Xe] clearance methods) and metabolism was investigated in 57 patients with recent cerebral infarction. Hemispheric blood flow (HBF) increased, together with increase in regional cerebral blood flow (rCBF) and cerebral blood volume (rCBV), in foci of brain ischemia. Hemisphe...

Longitudinal connectivity is a fundamental characteristic of rivers that can be disrupted by natural and anthropogenic processes. Dams are significant disruptions to streams. Over 2,000,000 low-head dams (<7.6 m high) fragment United States rivers. Despite potential adverse impacts of these ubiquitous disturbances, the spatial impacts of low-head dams on geomorphology and ecology are largely un...
