Ground-based photometry of bright stars is expected to be limited by atmospheric scintillation, although in practice observations are often other sources systematic noise. We analyse 122 nights star ($G_{mag} < 11.5$) using the 20-cm telescopes Next-Generation Transit Survey (NGTS) at Paranal Observatory Chile. compare noise properties theoretical models and we demonstrate that NGTS indeed scin...

plant performance and freshness is related to the pattern of its root growth development, which is highly affected by the water amount and water use management. therefore, the spatiotemporal variation of maize root under five treatments including full irrigation treatment (fi), partial root-zone drying treatments at two levels (receiving 75% of et =prd75, and 55% of et= prd55) and deficit irrig...

Introduction: Today, temporary or permanent venous catheters are being increasingly used in patients with renal failure. It seems a necessity to be familiar with their clinical applications and complications as well as their efficacy. The aim of this study was to compare the efficacy of two catheters of 16 cm and 20 cm lengths. Methods: This research project was a descriptive, analytic study...
