The Methanosarcina barkeri serC gene, encoding phosphoserine aminotransferase, was cloned by complementation of an Escherichia coli mutant, and its nucleotide sequence determined. M. SerC protein shares significant homology with other known proteins. E. hosts carrying the gene express aminotransferase activity, verifying function this gene.
As basic data, the river networks and water resources zones (WRZ) are critical for planning, utilization, development, conservation management of resources. Currently, network WRZ world most obtained based on digital elevation model data automatically, which not accuracy enough, especially in plains. In addition, code is inconsistent with network, hindering efficiency hydrology research. Based global 90-meter DEM combined a large number auxiliary this paper proposed series methods generating...
Under the influence of global climate change, discharges major rivers directed into ocean have undergone significant changes. To study trends and causes in discharge variation, we selected 40 large analyzed their annual near estuaries from 1960 to 2010. The method runoff variation attribution analysis based on Budyko hypothesis for large-scale basins was developed, which influencing factors human activities glacial melting were added formula. contribution rate changes quantitatively...
The electric properties of as-prepared and annealed Au/SrTiO3:Nb heterojunctions are comparatively investigated. former junction has hysteretic current-voltage apparent capacitance-voltage characteristics, showing significant resistance switching effects. latter behaves like a conventional semiconductor Schottky contact with negligible phenomena. Based on the equivalent circuit analysis, we demonstrated that hysteresis measured relation is caused by leakage resistance. Its real capacitance...
We studied the evolution of structural, electric, magnetic, and multiferroic properties with x in Fe1+xV2−xO4 (0 ≤ 0.4) spinels. For = 0, three successive phase transitions occur from high to low temperatures: cubic-tetragonal (c < a) at TS, tetragonal paramagnetic-orthorhombic ferrimagnetic TN1, orthorhombic collinear spin-tetragonal > noncollinear spin TN2. Below TN2, magnetic field dependent ferroelectricity was observed. With increasing 0 0.3, TN1 increased, while TS TN2...
In the context of climate change, extreme precipitation events over most mid-latitude land masses and wet tropical regions will very likely become more intense frequent, which may cause increases in intensity frequency drought or flood events.To explore mechanism dynamic functional changes ecosystems driven by (EDFEs) future interaction between two, this study focuses on mutual feedback relationship EDFEs ecological succession vegetation.To accomplish target, we reviewed relevant studies...
Waste electrical and electronic equipment (WEEE or e-waste) is a significant urban mine in the Beijing-Tianjin-Hebei region. A comprehensive systematic assessment of amount e-waste generated region resources environmental benefits recycling can provide scientific basis methods to support collaborative accurate management solve resource problems. Based on improved ownership coefficient method, material market value pollution this study predicted evaluated potential from 2010 2025 by...
This study analysed the temporal and spatial changes in water yield coefficient (WYC), which represents ratio of gross amount resources to precipitation. Factors such as precipitation, rainstorm days, rainless vegetation cover change, land use/cover change were considered determine causes these changes. The results led following conclusions: <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mo stretchy="false">(</mml:mo><mml:mn fontstyle="italic">1</mml:mn><mml:mo...
Abstract Land use/cover change plays an important role in human development and environmental health stability. Markov chain a future land use simulation model were used to predict simulate the spatial distribution of Huang-Huai-Hai river basin. The results show that cultivated grassland are main land-use types basin, accounting for about 40% 30%, respectively. area decreased artificial surfaces increased from 1980 2010. degree dynamic after 1990s was greater than before 1990s. There is high...
Abstract. More and more high-resolution data sets are simulated worldwide used in various research. However, addition to the improvement accuracy, practical significance of spatial distribution must also be considered. Considering that most accurate water withdrawal mainly provided by state, is concentrated on artificial surface cultivated land. Whenever possible, using published regional or national governments interpolating extending them specific land uses will maximize accuracy. Based...
Conflict decision is a continuous process in dynamic conflict environment. The evaluation of the situation basis making proper decisions at different stages process. Traditional approaches are static and do not consider enough impact factors real environment, so cannot reflect its evolution. This paper presents framework for supporting environments. includes timed models force, situation, psychological pressure, as well graphical trend analysis approach. has been applied to virtual military...
The Yangtze River Basin is the largest river basin of Asia and third world, gross water resources amount ranks first in basins country, it occupies an important position national strategic layout. Under influence climate change human activities, cycle has changed. temporal spatial distribution precipitation more uneven floods are frequent. In order to explore yield condition Basin, we selected Water Yield Modulus (WYM) as evaluation index, then analyzed evolution characteristics WYM by using...
