The mountainous massif of Sicó, in the centre of Portugal, is an extensive area composed of calcareous Jurassic formations. Hillside calcareous soils, with high pH, present chemical restrictions to support plant growth and are subjected to important erosion processes leading to their degradation if not protected by vegetation. In a first year of study some soil physicochemical characteristics h...

Data from 183 animals raised in 61 flocks were collected to investigate the morphological characteristics of the Northern Morocco goat. Nine zoometric measures and seven combined indices were obtained. Three zones were defined  based on geo-climatic characteristics and environmental influences: Mediterranean, Atlantic and Dual. The morphological variables showed the absence of sexual dimorphism...

in order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(triticum aestivum l.), an experiment was carried out at the experimental farm of shiraz university. results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...

Background: Sediments are inseparable fractions of wetland ecosystems that work as a his-torical archive in the process of recording heavy metal aggregation changes. This study was carried out for assessing Co, Ni, and Zn in sediment samples of Mighan Wetland using geo-accumulation index in 2013. Methods:The sediment samples were taken from 11 stations. The samples were subjected to bulk dige...

The structures of three xGeO(2)-(1- x)P(2)O(5) glasses, where x = 0.98,0.88, and 0.81, have been studied by neutron and x-ray diffraction experiments that yield well resolved P-O and Ge-O bond distances. The Ge-O coordination number (N(GeO)) increased from 4.0 ± 0.2 to 4.5 ± 0.2 with the decrease in x from 0.98 to 0.81. The increase in N(GeO) is consistent with a structural model that assumes t...

Correlations among interface properties and chemical bonding characteristics in HfO 2 /GeO x N y /Ge MIS stacks were investigated using in-situ remote nitridation of the Ge (100) surface prior to HfO 2 atomic layer deposition (ALD). Ultra thin (~1.1 nm), thermally stable and aqueous etch-resistant GeO x N y interfaces layers that exhibited Ge core level photoelectron spectra (PES) similar to st...
