Abstract Most ecological communities harbor many rare species (i.e., the rare biosphere), however, relatively little is known about how distinct ecological processes structure their existence.Here, we used spatiotemporal data on soil bacterial communities along a natural ecosystem gradient to model the relative influences of assembly processes stru
Nighttime Lights and Population Migration: Revisiting Classic Demographic Perspectives with an Analysis of Recent European Data
This study examines whether the Visible Infrared Imaging Radiometer Suite (VIIRS) nighttime lights can be used Drawings and Etchings to predict population migration in small areas in European Union (EU) countries.The analysis uses the most current data measured at the smallest administrative unit in 18 EU countries provided by the European Commissi
Volatile constituents and oxidative stability of virgin olive oils: influence of the kneading of olive-paste.
Olive crushing, olive-paste kneading and separation of the oil the most important technological steps in olive oil production since they directly influence the future quality of the product.The contact between the oil and the olive-paste increases lipolysis and lipid oxidation, which are mainly due to the highly-active lipases present in Drawings a
Flexible retrospective phase stepping in x-ray scatter correction and phase contrast imaging using structured illumination.
The development of phase contrast methods for diagnostic x-ray imaging is inspired by the potential of seeing the internal structures of the human body without the need to deposit any harmful radiation.An efficient class of x-ray phase contrast imaging and scatter correction methods share the idea of using structured illumination in the form of a p
Synthesis , Characterization , and study of the Spectral and Electronic Properties of a New Azo Dyes Compounds
In this study two new azo dyes were prepared from 4-acetaminophenol with 4-amino-N-2-pyrimidinylbenzenesulfonamide & 4-amino-N-(5-methyl-3-isoxazolyl)-benzenesulfonamide were prepared.The prepared by Fox method, the azo dyes were identified by IR- spectrophotometer, UV-visible spectroscopy and elemental analysis (CHN).The absorption spectra of the
