Serratia marcescens is an opportunistic and nosocomial pathogen found in the intensive care unit (ICU), but its antimicrobial resistance (AMR) rarely addressed. Here, we reported two blaKPC-2-positive S. strains, SMBC31 SMBC50, recovered from ICU of a hospital Zhengzhou, China. The minimum inhibitory concentration (MIC) was determined using broth microdilution method, while S1-PFGE employed to demonstrate plasmid size approximation. Complete genome sequences were obtained through Illumina...
This paper investigates the impact of population aging on firms' international sourcing strategies, using data from Chinese listed manufacturing firms 2002 to 2016. Our results show that increase their import activities in response higher levels local aging, particularly by intermediate inputs. effect is more pronounced for labor-intensive firms, those dependent upstream suppliers, and highly competitive markets, suggesting utilize address labor market challenges stimulate product demand....
Abstract It is generally accepted that carbon from Earth’s surface can be recycled into the mantle during oceanic subduction, thereby playing an important role in global cycle. However, evidence as to whether contains carbonates, and of which types, remains ambiguous. Here, we present Mo-Mg isotopic data for two distinct mafic rock types Lhasa terrane, southern Tibet: Taruocuo gabbros Zhongba basalts. These units were formed response Neo-Tethys subduction at sub-arc post-arc depths mantle,...
Abstract The Longshou Shan of western China is the northern backstop Cenozoic Himalayan-Tibetan orogen and occupies a key linkage between Tarim continent North craton which separate pre-Cenozoic Tethyan orogenic system Central Asian system. Therefore, Paleoproterozoic–Paleozoic evolution this region critical to understanding extent overprinting deformation, construction Eurasian continent, relationships Here we present detailed field observations results geochronological major trace element...
Geochemical maps play an important role in mineral resource exploration. There are three traditional methods for creating geochemical maps: the cumulative frequency method, logarithmic interval and Avg±k∗Std (where Avg Std abbreviations of average standard deviation, k is a multiple Std) method. However, with increasing scope study area data, limitations methods, which depend on amount exposed. A fixed-value method Sn geological mapping proposed to overcome methods. In concentrations divided...
Conventional wisdom holds that one-party regimes are intrinsically hostile to civil society because organized citizens can threaten the regime's political dominance. Contrary this view, authors argue genuinely voluntary organizations may be tolerated, or even actively promoted, by governments in a system when those help efficiently resolve intrasocietal distributional conflicts arising from economic modernization. Using China's homeowner associations (hoas) as case, article demonstrates...
Geochemical gene is a new promising concept proposed recently in the discrimination and traceability of geological materials also useful tool to recognize geochemical anomalies mineral exploration. Based on lithogenes LG01 LG03, can be classified into nine types LG_CR compositionally. With respect with 11 LG_CR, order eliminate lithological influence further narrow prospecting target area, tungsten metallogene named MGW11 for exploration after MGW. Six weathering profiles developed granitic...
To evaluate the homogeneity of geological reference material BIR ‐1a (basalt; United States Geological Survey, USGS ) for Re‐Os isotopic studies at 0.2–1.0 g test portion size level, sixty‐three precise measurement results Re and Os mass fractions isotope amount ratios were obtained over an 18‐month period. These data reveal that has higher (0.691 ± 0.022 ng −1 , 2 s n = 63) lower (0.343 0.089 than UB ‐N (serpentinite, CRPG is homogeneous in 187 Os/ 188 ratio (0.13371 0.00092, level. The are...
As geographic environment is an expression of the geological settings, it objective this research to explore roles background in society development, particular, city development. Based on field trips, and tectonic maps, digital elevation model (DEM) Google Earth images were utilized for study. Simple linear binary logistic regression (BLR) a set spatial analysis applied impacts environmental factors distribution its relationship with taking Jiangxi, China as example. Here we show that all...
In recent decades, the human demand for mineral resources has increased dramatically, and mining of shallow deposits basically been completed. The prospecting direction turned to concealed deposits. For this reason, various penetrating geochemical methods have developed find minerals a series exploration techniques proposed. At same time, use gene as new technique presented in years is feasible discussing component classification provenance tracing. study, we applied these Jiaojia gold...
Knowledge is a contribution factor leading to more effective and efficient construction safety management. Metro practitioners always find it difficult determine what specialized knowledge needed in order lead better risk Currently, domain elements are generally determined by experts, which coarse-grained uncomprehensive. Therefore, this paper aims provide structure of elements, using an automatic approach expand (DKEs) from big dataset unstructured text documents. First, the co-word...
The successful return of Chang’E-5 (CE5) samples urges the hot topic study Moon in geochemistry. elemental data analyzed moon reported literature were collected to determine abundances samples. Based on 2365 analytical records from ten missions Apollo, Luna, and CE5, 11 major oxides including Cr2O3, 50 trace elements Ti, P, Mn, Cr, 15 rare earth (REEs) Y are derived based statistical distributions normal, log-normal, additive log-ratio transformation, respectively. According value 13.5% CaO...
Dendrite, a typical geological pattern, is developed along the bedding plane in limestone and dolomite strata Jinzigou area, Zhoukoudian, Beijing, China, with self-similar dendritic morphology. In order to reveal dynamic mechanism of its formation, diffusion-limited aggregation method, model fractal growth, was selected simulate microscopic formation. Take an L × square lattice, = 200 lattices, 20,000 particles, 250 30,000 for simulation. Obtain simulation results pattern intermediate 8057...
Inverting soil parameters through hyperspectral techniques is currently one of the highly popular research topics and major challenges in quantitative remote sensing. To date, indoor spectral data-based inversion models cannot be directly applied to satellite-based data, due weak model migration capability caused by large differences between two data. Therefore, present study aims improve parameter accuracies using GF-5 sensing data merging multiple First, Analytical Spectral Devices (ASD)...
The largest negative carbon-isotope excursion in geological history has been reported by several studies of the upper Doushantuo Formation South China, which correlated to middle Ediacaran-Shuram (SE). Due a scarcity radiometric age constraints on however, global correlations and comparisons this event remain debate. Here, we present Re–Os carbon isotope data organic-rich sediments obtained from drill-core sample Chengkou area, northeastern margin Yangtze Platform, China. geochronology...
In this work, the isothermal liquid–liquid equilibrium (LLE) and isobaric vapor–liquid (VLE) of methacrolein–methacrylic acid–water ternary mixture were systematically measured using an LLE cell improved Rose–Williams still under atmospheric pressure. The thermodynamic consistency data VLE was tested by Othmer–Tobias Van Ness methods, respectively. NRTL, UNIQUAC, Wilson activity coefficient models have been conducted to correlate binary parameters in prediction phase based on experimental...
