Background and objectives: Many clinicians believe that low-dose dopamine (LDD) [2 g/kg/min] increases renal blood flow (RBF) and medium-dose norepinephrine (MD-NE) [0.4 g/kg/min] decreases RBF. They also believe that MD-NE might induce mesenteric and/or coronary ischemia. In fact, the effects of these drugs on renal and vital organ blood flow are poorly understood. The aim of this study was to...

Seed dispersal plays an important role in population dynamics agricultural ecosystems, but the effects of surrounding vegetation height on seed and connectivity landscape scale have rarely been studied. Understanding will provide information for land-use management landscapes to prevent spread undesired weeds or enhance functional connectivity. We used two model species, Phragmites australis Ty...

Vibration and noise must be considered to maximize the efficiency of a yaw system reduce fatigue load acting on wind turbine. This study investigated method for analyzing yaw-system vibration based change in load-duration distribution (LDD). A substructure synthesis was combined with planetary gear train rotational model finite element models housing carriers. For excitation sources, mass imbal...

We report a case of a 37-year-old woman presenting with dysphagia and thyroid masses who was subsequently diagnosed with Lhermitte-Duclos disease (LDD) based on MRI scan and histopathology. Additional imaging subsequently revealed the presence of thyroid nodules and bilateral breast cancers. Genetic testing later confirmed the diagnosis of Cowden syndrome. This case illustrates the importance o...

This paper shows how finite approximations of long distance dependency (LDD) resolution can be obtained automatically for wide-coverage, robust, probabilistic Lexical-Functional Grammar (LFG) resources acquired from treebanks. We extract LFG subcategorisation frames and paths linking LDD reentrancies from f-structures generated automatically for the Penn-II treebank trees and use them in an LDD...

Anisotropic (direction-dependent) long-distance dispersal (LDD) by wind has been invoked to explain the strong floristic affinities shared among landmasses in the Southern Hemisphere. Its contribution has not yet been systematically tested because of the previous lack of global data on winds. We used global winds coverage from the National Aeronautics and Space Administration SeaWinds scatterom...

In this paper bit error rate (BER) performance is analyzed for multiple input-multiple output (MIMO) communications systems using antenna selection in the transmitter, maximal ratio combining (MRC) and linear de-correlating detector (LDD) in the receiver in wide band code division multiple access (WCDMA) downlink channels with correlated Nakagami fading. The MRC maximizes signal to noise ratio ...

Long-distance dispersal (LDD) is a critical process in the distribution of less-migratory organisms. Migratory birds are considered principal vector LDD, especially over extremely long distances such as between continents. However, there has been no evidence LDD spanning thousands kilometers, even via birds. In this study, we collected freshwater snail attached to Latham's snipe. This was ident...

OBJECTIVES A previous study identified a significant association between several single nucleotide polymorphisms (SNPs) and lumbar disc degeneration (LDD) in Indians. To validate the association between these SNPs and specific lumbar spine pathologies, we performed a case-control study in Chinese Han population. DESIGN An observational study. SETTING University Hospital in Nanning, China. ...

OBJECTIVES Lumbar disc degeneration (LDD) is prevalent, age-related and contributes to low back pain. Cross-sectional LDD as determined by MRI scan is known to be highly heritable. The authors postulated that the rate of progression might also be controlled by genetic factors. METHODS A 10-year follow-up of MRI-determined LDD was performed in 234 pairs of twin volunteers in the UK and Austral...
