Clinical decision-making by the emergency department resident physicians for critically ill patients

Tengda Xu, Jun Xu, Xuezhong Yu, Sui Ma, Zhong Wang

Frontiers of Medicine 2012, Volume 6, Issue 1,   Pages 89-93 doi: 10.1007/s11684-012-0183-9

Abstract:

The application of main methodologies for clinical decision-making by residents in emergency medical practice was assessed, and issues in this area were investigated. The treatments provided to 2 611 critical patients by the Peking Union Medical College Hospital of were analyzed by independent investigators who evaluated the main clinical decision-making processes applied by the hospital residents. The application of decision-making strategies by PG1 and PG3 groups, which means the residents in first year and the third year, were compared. The patients were treated according to pattern recognition (43.0%), hypothetico-deductive reasoning (23.4%), event-driven models (19.3%), and rule-using algorithms (5.9%). A significant difference was found between PG1 and PG3 groups (χ2=498.01, P<0.001). Pattern recognition and hypothetic-deductive methods were the most common techniques applied by emergency physicians in evaluating critically ill patients. The decision-making processes applied by junior and senior residents were significantly different, although neither group adequately applied rule-using algorithms. Inclusion of clinical decision-making in medical curricula is needed to improve decision-making in critical care.

Facile route to achieve MoSe-NiSe on nickel foam as efficient dual functional electrocatalysts for overall

Frontiers in Energy 2022, Volume 16, Issue 3,   Pages 483-491 doi: 10.1007/s11708-022-0813-0

Abstract: Since the catalytic activity of present nickel-based synthetic selenide is still to be improved, MoSe2-Ni3Se2 was synthesized on nickel foam (NF) (MoSe2-Ni3Se2/NF) by introducing a molybdenum source. After the molybdenum source was introduced, the surface of the catalyst changed from a single-phase structure to a multi-phase structure. The catalyst surface with enriched active sites and the synergistic effect of MoSe2 and Ni3Se2 together enhance the hydrogen evolution reactions (HER), the oxygen evolution reactions (OER), and electrocatalytic total water splitting activity of the catalyst. The overpotential of the MoSe2-Ni3Se2/NF electrocatalyst is only 259 mV and 395 mV at a current density of 100 mA/cm2 for HER and OER, respectively. MoSe2-Ni3Se2/NF with a two-electrode system attains a current density of 10 mA/cm2 at 1.60 V. In addition, the overpotential of HER and OER of MoSe2-Ni3Se2/NF within 80000 s and the decomposition voltage of electrocatalytic total water decomposition hardly changed, showing an extremely strong stability. The improvement of MoSe2-Ni3Se2/NF catalytic activity is attributed to the establishment of the multi-phase structure and the optimized inoculation of the multi-component and multi-interface.

Research on overall encryption adjustment technology of offshore oil field

Zhang Fengjiu,Luo Xianbo,Liu Yingxian,Zhao Chunming

Strategic Study of CAE 2011, Volume 13, Issue 5,   Pages 34-40

Abstract:

Take SZ36-1 oilfield as an example, offshore fields of heavy oil have stepped into later stage in development life and revealed problems gradually for serious injection/production contradiction, big variation for producing reserves in interlayer and plane, much higher for well-controlled reserves, lower for both of oil production rate and oil recovery, changing fast for composite water cut rising and production decline. In view of the challenge for development of offshore fields of heavy oil in China, we put forward the study of comprehensive adjustment for offshore fields in large scale firstly. Because of the special development mode of offshore fields, the proven research thinking and technical route for comprehensive adjustment used by onshore oilfields could not be copied to offshore fields. The research technology of comprehensive adjustment for integral well pattern thickening faces many technical difficulties, so now this research makes a combination of self-characteristics and development mode of SZ36-1 oilfield to put forward a full suite of research thinking and research methods for integral potential tapping and adjustment, and the proposal of comprehensive adjustment for integral well pattern thickening in SZ36-1 oilfield phase I. A water injection well pattern of inverted nine spot is transformed into a well pattern of line drive after pattern adjustment to try a development modes of "direction well & horizontal well network" . The implementation effect of integral well pattern thickening makes a good effect for greatly improved state of water flooding, improved from 80.5 % before adjustment to 91.3 % after adjustment for producing degree of water flooding, forecasting greatly improved recovery for 10.4 %. The technique of adjustment for integral well pattern thickening is sure to be popularized and applied among the similar oilfields.

Xiaonong GUO,Shuiping LIANG,Zuyan SHEN

Frontiers of Structural and Civil Engineering 2015, Volume 9, Issue 1,   Pages 48-64 doi: 10.1007/s11709-014-0271-9

Abstract: To improve the design methods of Chinese aluminum alloy members, experiment of 63 profiled aluminum alloy members, made of Chinese aluminum alloy 6061-T6, under axial compression is conducted in this paper. Valuable experimental data are obtained. At the same time, in order to obtain the relevant data, a large number of other experimental data from published papers and technical reports are collected and sorted out. 167 valid experimental data points are obtained finally. Furthermore, for the purpose of creating column curves, the aluminum alloy members under the axial compression, used in experiments, are analyzed by means of FEM. Based on the numerical results, 2 column curves are created by means of the numerical fitting method. The column curves are compared with the calculated data according to the experimental results for verification, and also are verified with the curves in design codes of several relevant countries. The numerical results show that the column curves obtained in this paper are valid and reliable.
