The objective of this study was to characterize the structure and function of microbial communities in surface seawater from the Changjiang Estuary and adjacent areas, China. Sample water was collected at 12 sites and environmental parameters were measured. Community structure was analyzed using high-throughput sequencing of 16S rDNA genes. Predictive metagenomic approach was used to predict th...

Destructive communication is a problem within the NHS; however previous research has focused on bullying. Rude, dismissive and aggressive (RDA) communication between doctors is a more widespread problem and underinvestigated. We conducted a mixed method study combining a survey and focus groups to describe the extent of RDA communication between doctors, its context and subsequent impact. In to...

Abstract In general redundancy allocation problems the redundancy strategy for each subsystem is predetermined. Tavakkoli- Moghaddam presented a series-parallel redundancy allocation problem with mixing components (RAPMC) in which the redundancy strategy can be chosen for individual subsystems. In this paper, we present a bi-objective redundancy allocation when the redundancy strategies for...

Bioretention systems are an important measure in sandy city construction to remove pollutants. This study collected all the operating data samples of bioretention ponds currently operation China and used Mantel test Redundancy Analysis (RDA) optimize main factors that affect changes pollutant-removal efficiency. Genetic Algorithms (GA) were Back Propagation (BP) neural network model, a predicti...

The change and intensification of land use has been generating impoverishment soils with negative effects on biological communities. It was analyzed the bacterial composition maca (Lepidium meyenii Walp) cultivation by Illumina sequencing in Bombón plateau, during 2019. Three sampling sectors were defined, a control sector (natural soil) two pressure ("first use" "second soils). Soil physicoche...

Soil microorganisms directly participate in phosphorus (P) cycle, which turn affects crop yield and quality. However, how biological chemical parameters respond to mineral P fertilizer application rates rhizosphere soil remains unclear. Here, a pot experiment was conducted investigate the effects of different (0, 60, 120, 300 kg P2O5 ha−1) on properties bacterial community maize Mollisol. With ...

Forty patients with "rate dependent aberrancy" (RDA) were studied. This large group of patients permitted a clear definition of the syndromne and recognition of a number of features not previously described. These proved to have a significant bearing on the recognition and differential diagnosis of RDA and non-rate dependent aberrancy. It was found that a small change in cycle length, perhaps t...

To explore how climatic factors influence tree growth within the context of global climate changes, we used a dendroclimatological analysis to understand the response of Larix gmelinii to climatic variations along a broad latitudinal gradient from 47.27◦ to 52.66◦ N in the Greater Khingan Mountains of Northeastern China. The growth-limiting climate factors and a detailed association between rad...

Microbes have great potential for arsenic (As) and antimony (Sb) bioremediation in heavily contaminated soil because they have the ability to biotransform As and Sb to species that have less toxicity or are more easily removed. In this study, we integrated a metagenomic method with physicochemical characterization to elucidate the composition of microbial community and functional genes (related...

Epidemiological evidence suggests that infection is involved in the etiology of common acute lymphoblastic leukemia, either by stimulating an inappropriate immune response or in the form of a classical transforming agent. In an attempt to elucidate the role that infection is playing in this disease, we used representational difference analysis (RDA) to examine tumor samples for the presence of ...
