Our aims were to assess the relationship between workplace violence, job satisfaction, burnout, organisational support and turnover intention, explore factors associated with intention among nurses in Chinese tertiary hospitals.The purposive sampling method was used collect data from August 2016 through January 2017. A total of 1761 9 public hospitals 4 provinces (municipalities) located eastern (Beijing), central (Heilongjiang, Anhui) western (Shaanxi) regions China completed questionnaires...
Objectives Post-traumatic stress disorder (PTSD) is a common psychological maladjustment to undergoing traumatic event. Our aim was measure the prevalence of PTSD among Chinese healthcare workers exposed physical violence‚ and explore associations their demographic characteristics, social support, personality traits‚ coping styles with symptoms. Methods A cross-sectional study conducted using Workplace Violence Scale, Posttraumatic Stress Disorder Checklist-Civilian Version (PCL-C), Social...
Background and aim The doctor–patient relationship has been a major focus of society. Hospitals' efforts to improve the quality their medical services have reduce probability conflicts. In this study, we aimed determine gap between expectations perceptions service according patients provide reference data for creating strategies health care quality. Methods Twenty–seven hospitals in 15 provinces (municipalities directly beneath central government) were selected our survey; sent out 1,589...
Abstract The development of materials integrated with ultrasmall multi‐metal nanoparticles (UMMNs) and mesoporous zeolite is a considerable challenge in chemistry science. We designed trifunctional surfactant, which the pyridyl benzimidazole hydrophobic tail generates mesopores through π–π stacking; diquaternary ammonium hydrophilic headgroup direct formation MFI sheets nitrogen atoms heterocyclic rings coordinate various metal ions to form UMMNs confined matrix after calcination reduction....
Precise locating and correct classification of each defect in the image is primary goal surface detection (SDD). This very similar to object detection, which seeks predict a set bounding boxes (Bboxes) category labels for interest. However, due fact that dependencies among defects are obviously different from those general objects, methods developed cannot be directly utilized detecting defects. To address this issue, we proposed category-related non-maximum suppression (CR-NMS) method....
Functional ionic liquids have been widely used in the fields of synthetic chemistry, analytical electrochemistry and material chemistry owing to their excellent properties such as easy structure modification adjustable properties. In this work, a series basic functionalized were prepared from 1, 4-diazabicyclo [2.2.2] octane (DABCO) or hexamethylenetetramine (HMTA) with various halogenated hydrocarbons, then these functional water solvent-catalyst system Knoevenagel reaction aldehydes ethyl...
The development of a catalyst for the conversion CO2 and epoxides to corresponding cyclic carbonates is still very attractive topic. Magnetic nano-catalysts are widely used in various organic reactions due their magnetic separation recycling properties. Here, nano-catalyst containing Schiff base unit was designed, synthesized as heterogeneous catalyze form without solvents co-catalysts. characterized using Fourier transform infrared (FTIR), X-ray diffraction (XRD), thermogravimetric (TG),...
In order to develop a functional ionic liquid catalyst with good stability and excellent catalytic effect on the organic reactions under alkaline conditions, magnetic nanocatalyst of tertiary amine incorporated Fe3O4 was prepared applied in Knoevenagel reaction, exhibits performance short reaction time yields products were obtained. addition, can be separated rapidly external force reused for 8 times without significant loss activity. Through activity comparison FTIR, XRD, TG, VSM, SEM, TEM,...
A series of basic functional ionic liquids were prepared from 1, 4-diazabicyclo [2.2.2] octane (DABCO) with various halogenated hydrocarbons, then these used as catalysts for the chemical fixation CO2 into cyclic carbonates and influence structure was investigated. The results showed that N atom active center, types anions hydrogen bond catalyst play a key role in cycloaddition reaction epoxides to carbonates. Under mild conditions (T = 100 °C, 1 atm CO2), liquid [DABCO-CH2CH2CH2OH] I best...
Capex guidance disclosed by a firm’s peers provides useful information about their peers’ investment plans. In this study, we find positive association between capex and managerial learning opportunities from stock prices as captured the sensitivity of to Tobin’s Q, which is consistent with disclosure plans encouraging investors’ processing thereby providing price–based feedback managers. cross-sectional analyses, relationship more pronounced when peer informative, managers have greater...
Understanding of epitaxial and rotational intergrowth is particularly important for the design synthesis hierarchically structured zeolites. Herein, we propose a new route fabricating hierarchical MTW- MFI-type zeolites with intergrown structures by tuning methylene chain lengths between two N-heterocycles in bolaform quaternary ammonium structure-directing agents (SDAs). MTW-type 66.4° 90° were synthesized 4–6 7–9, respectively. A possible theoretical evidence geometrical match SDAs zeolite...
Green infrastructure is imperative for efficiently mitigating flood disasters in urban areas. However, inadequate green space planning under rapid urbanization a critical issue faced by most Chinese cities. Aimed at theoretically understanding the rainwater storage capacity and improvement potential of spaces, synthetic simulation model was developed to quantify rainfall surface flow accumulation (FA) based on morphological factors basin: area, circumference, maximum basin length, stream...

Nowadays, more and databases are distributed in networks. To produce knowledge with the databases, traditional data mining technology should be developed model, algorithm, strategy, etc. The popular (DDM) systems introduced classified into three classes: DDM based on parallel agents, meta-learning, Grid. According to analysis of main classes systems, problems decreasing system utility concluded; a novel model related integrating proposed.
Natural frequencies of powertrain mount brackets have great influences on NVH (Noise, Vibration, Harshness) performances a Powertrain Mount System.
