Ecological reconstruction on bauxite residue (tailings) disposal areas is regarded as an effective approach to eliminate potential environmental risks. Establishment of microbial communities and associated functions may improve physical chemical properties, stimulate soil formation in residue. Spontaneous colonization at a area Shandong Province, China, over 50 years, indicated that natural wea...

An understanding of the annual variations in phytoplankton community freshwater lakes, and drivers responsible for these variations, is essential lake management. In this study we collected analyzed seasonal samples assessed environmental variables Nansi Lake from 2011 to 2015, order identify dynamics main each phylum. The results showed that diversity followed cycles, which were interrupted by...

Soil microorganisms and dissolved organic matter (DOM) play vital roles in nutrient cycling maintaining plant diversity. The aim of this study was to clarify the relationship between DOM component characteristics microbial community structure soil Larix principis-rupprechtii Mayr. plantations. We quantified responses stand age a plantation forest ecosystem using phospholipid fatty acid (PLFA) a...

The forest ecosystem is the largest carbon reservoir in terrestrial ecosystem, with soil organic (SOC) being its most important component. How does distribution of SOC change under influence regional location, succession, human activities, and depth? It basis for understanding evaluating value reservoirs improving function sinks. In this paper, concentrations (SOCCs) environmental factors were ...

This paper presents the Remote Device Access (RDA) package developed at CERN in the framework of the joint PS/SL Controls Middleware project. The package design reflects the Accelerator Device Model in which devices, named entities in the control system, can be controlled via properties. RDA implements this model in a distributed environment with devices residing in servers that can run anywher...

BACKGROUND One of the factors that affect the recurrence rate after peripheral directional atherectomy (DA) is the degree of residual stenosis. A new method of peripheral DA to reduce residual stenoses was evaluated with a rotational digital angiography (RDA) system that provides both angiography and fluoroscopy at multiple projections within 360 degrees. PATIENTS AND METHODS Between March 19...

the study was performed for assess the environmental factors affecting weed species diversity and composition of wheat (triticum aestivum l.) fields in jajarm, north-khorasan of iran, in 2009. the crop management (herbicide, amount of nitrogen applied and preceding crop type) and edaphic factors (ph, texture and content of phosphorus) of 16 fields were collected. shannon’s diversity index, spec...
