The Soil and Water Assessment Tool(SWAT)model was used to assess the impacts of different land use scenarios on hydrological processes in the Fuhe watershed in Poyang Lake Basin,East China.A total of 12 model parameters were calibrated with observed monthly runoff data for 1982-1988 and validated for 1991-1998 for baseline *** baseline test results of R2 and Nash-Sutcliffe model efficiency(NSE)values ranged between 0.88 and 0.94 across the calibration and validation periods,indicating that SWAT accurately replicated the Fuhe watershed *** different land use scenarios were then simulated with the model,focusing on the impacts of land use change on the hydrology of the *** results of hypothetical scenario simulations revealed that surface runoff declined while groundwater recharge and evapotranspiration(ET)increased,as forest land,agriculture land and/or grassland areas increased,as well as when paddy field and urban areas *** results further showed that forest land has a higher capacity to conserve the water as compared to pasture *** results of the real scenario simulations revealed that urbanization is the strongest contributor to changes in surface runoff,water yield,and *** can be considered as a potential major environmental stressor controlling hydrological components.

Strain engineering is a powerful tool to tailor the physical properties of materials coherently stacked in an epitaxial heterostructure. Such an approach, applied to the mature field of planar heteroepitaxy, has yielded a variety of new phenomena and devices. Recently, heteroepitaxial vertically aligned nanocomposites have emerged as alternatives to planar structures. Owing to the peculiar geometry of such nanoarchitectures, efficient strain control can be achieved, opening the way to novel functionalities. In this paper, we report a very large tensile axial strain in epitaxial transition metal nanowires embedded in an oxide matrix. We show that axial strains in excess of 1.5% can be sustained over a large thickness （a few hundred nanometers） in epitaxial nanowires having ultrasmall diameters （-3-6 nm）. The axial strain depends on the diameter of the nanowires, reflecting its epitaxial nature and the balance of interface and elastic energies. Furthermore, it is experimentally shown that such strain is metastable, in agreement with the calculations performed in the framework of the Frenkel-Kontorova model. The diameter dependence and metastability provide effective ways to control the strain, an appealing feature for the design of functional nanoarchitectures.

Characterization of the Bacillus subtilis Penicillin-Binding Protein PBP4

Advances in Microbiology 2019年第3期9卷 164-176页

作者： Arnaud Vanden Broeck Eric sauvage Bernard Joris Colette Duez Institut de Chimie Centre for Protein Engineering University of Liège Liège Belgium Institut de Physique Centre for Protein Engineering University of Liège Liège Belgium

Purpose: The PBP4* is a Penicillin Binding Protein belonging to the class C of AmpH type whose function remains poorly understood. This study aimed to evaluate the biophysical and enzymatic properties of the Bacillus subtilis PBP4* to gain insights into its role in the context of bacterial cell wall recycling. Methods: To characterize the PBP4*, the full-length PBP4* and its N-terminal penicillin-binding domain have been produced in Escherichia coli and purified. Results: A comparison of biophysical properties has shown that both recombinant proteins are monomeric in solution and retain the same thermal stability. On the other hand, the D-alanine methyl esterase activity detected with the full-length PBP4* is impeded by the cleavage of the 92 amino acid C-terminal domain. The esterase activity of the full-length PBP4* strates a clear D-stereospecificity. The PBP4* is also active on B. subtilis cell walls bearing teichoic acids, compounds commonly substituted with D-alanine residues. Conclusions: Our results are in agreement with the hypothesis that PBP4* could play a role in recycling cell wall components, as previously suggested.

The analytical technique PIXE experiment for measuring light and heavy elements concentration inside different samples of soil and residual water collected in the region of Safi-El Jadida, where an industrial complex resided, was performed. The same method was used to investigate the presence of elements ranging from silicon to lead in different soils samples and seaweed collected upstream from the site of Safi-El Jadida industrial zone, inside lands and downstream of it, in the entrance of the Casablanca region. This study allows us to highlight the influence of activities of this industrial zone on the neighbouring areas the site.
