یکی از مشکلات مناطق خشک و نیمه خشک ایران، کمبود آب کشاورزی می باشد. برای رفع این مشکل، روش های آبیاری مختلفی مانند کم آبیاری، آبیاری بخشی و آبیاری بخشی متناوب برای این مناطق پیشنهاد شده است. در آبیاری بخشی (prd) نیمی از محیط ریشه به صورت کامل آبیاری شده و نیم دیگر خشک نگه داشته می شود. بخش های مرطوب شده و خشک نگه داشته شده طی یک سیکل زمانی تعویض می شوند. مطالعه حاضر در سال های 1388 و 1389 تحت ش...
By the 2050s, more than 120 million people are predicted to settle in Pearl River Delta (PRD), which covers large coastal cities such as Guangzhou, Shenzhen and Hong Kong. Cities PRD vitally important China relation their socio-economic contributions. From recent evidence, this strongly urbanized area is vulnerable to, currently facing bigger incidences of, urban flooding. Flood risk growing lo...
Analogue black holes in non-Riemannian effective spacetime of moving vortical plasmas described by moving magnetohydrodynamic (MHD) flows. This example is an extension of acoustic torsion recently introduced in the literature (Garcia de Andrade,PRD(2004),7,64004), where now the presence of artificial black holes in moving plasmas is obtained by the presence of an horizon in the non-Riemannian s...
I t is accepted that pressure relief is among the most important aspects in treating diabetic foot ulcers. Clinically, a variety of off-loading devices are used to redistribute pressure away from the area of ulceration to improve wound healing. The incorporation of pressure-relieving properties in a wound care dressing for the treatment foot ulcers is a new and interesting concept, although cur...
In this work, a novel wavelet-based denoising method for electrocardiogram signal is proposed. A threshold is derived by considering energy contribution of awavelet subband, noise variance which is based on a novel Gaussian measure, Kurtosis, and number of samples. The robust noise estimator, median absolute deviation, is scaled by a normalized wavelet subband Kurtosis instead of conventional s...
The synthesis of propanediol oxidoreductase, an enzyme permitting the anaerobic metabolism of fucose and rhamnose, has been described as being controlled by the prd locus closely linked to the fuc locus in wild-type cells of Escherichia coli. However, strain AA-787, deleted in the fuc and prd loci, grew anaerobically on rhamnose, displaying propanediol oxidoreductase activity. From the deleted ...
Data transported through the control system of WLAN included: burst real-time data (BRD), periodical real-time date (PRD) and non-real-time data (NRD). Priority ranged from the high level to the low level and distinguished them by different inter frame space (IFS). BRD station sent RTS to reserve channel freeing SIFS and transmitted burst data after SIFS; PRD transported through AP polling; non...
INTRODUCTION The application of high-throughput genomic approaches has revealed 24 novel risk loci for Alzheimer's disease (AD). We recently reported that the bridging integrator 1 (BIN1) risk gene is linked to Tau pathology. RESULTS We used glutathione S-transferase pull-down assays and nuclear magnetic resonance (NMR) experiments to demonstrate that BIN1 and Tau proteins interact directly a...
Over the past few thousand years, human development and population expansion in southern China have led to local extirpation and population contraction of many terrestrial animals. At what extent this early human-induced environmental change has also affected coastal marine species remains poorly known. We investigated the demographic history of the Indo-Pacific humpback dolphin (Sousa chinensi...
BACKGROUND It is still not known whether patients survive longer on one modality of dialysis compared to the other. We have tried to answer this question using data from the Scottish Renal Registry. METHODS To avoid the confounding effects of co-morbidity, we limited our survival analysis to those patients listed for a renal transplant and excluded patients with a primary renal diagnosis (PRD...
