This research examines Christian Spuck's from an expressionist perspective, analyzing the elements of hearing, vision, and movement to investigate the relevance of early 20th-century expressionist trends in the 21st century. The study aims to explore the impact of expressionist techniques on contemporary dance creation. In terms of auditory elements, modern music techniques are used to emphasize the characters' inner emotions and feelings. Visual factors, such as the use of a grey stage installation, minimalist LED lighting, and unusual props, reveal the characters' inner loneliness and expose the distortion of social values. Action elements, including turn-in and curvy action forms and the combination of continuous action with strange props, depict the characters' distorted images. Additionally, the use of canon technique and ABC format creates tension and propels the energy flow forward. Spuck's work enriches the expressionist vocabulary through the design of visual, auditory, and movement elements, offering new creative inspiration for emerging choreographers.

Development and verification of a novel system for computed tomography scanner model construction in Monte Carlo simulations

Liu Ying,Meng Ting,Zhang Haowei,Su Qi,Yan Hao,Lu Heqing 한국원자력학회 2022 Nuclear Engineering and Technology Vol.54 No.11

The accuracy of Monte Carlo (MC) simulations in estimating the computed tomography radiation dose is highly dependent on the accuracy of CT scanner model. A system was developed to observe the 3D model intuitively and to calculate the X-ray energy spectrum and the bowtie (BT) filter model more accurately in Monte Carlo N-particle (MCNP). Labview's built-in Open Graphics Library (OpenGL) was used to display basic surfaces, and constructive solid geometry (CSG) method was used to realize Boolean operations. The energy spectrum was calculated by simulating the process of electronic shooting and the BT filter model was accurately modeled based on the calculated shape curve. Physical data from a study was used as an example to illustrate the accuracy of the constructed model. RMSE between the simulation and the measurement results were 0.97% and 0.74% for two filters of different shapes. It can be seen from the comparison results that to obtain an accurate CT scanner model, physical measurements should be taken as the standard. The energy spectrum library should be established based on Monte Carlo simulations with modifiable input files. It is necessary to use the three-segment splicing modeling method to construct the bowtie filter model.

Yishan Wang,Shengyi Yang,Haowei Wang,Li Zhang,Haijuan Cheng,Bo He,Weile Li,Bingsuo Zou 한국물리학회 2017 Current Applied Physics Vol.17 No.3

In this paper, a simple and non-poisonous “surfactant treatment” method to prepare graphene oxide (GO) in organic solvents with good dispersibility was presented. As the surfactant molecules, didodecyldimethyla-mmonium bromide (DDAB) was attached onto the GO sheets via ionic interactions by mild sonication, the obtained GO:DDAB nanocomposites were then blended into copolymer Poly(3- hexylthiophene-2,5-diyl) (P3HT) [6,6]:-Phenyl C61 butyric acid methyl ester (PC61BM) as the active layer to fabricate bulk-heterojunction (BHJ) organic solar cells ITO/PEDOT:PSS/P3HT:PC61BM:(GO:DDAB)/ Ca/Al. The concentration of GO:DDAB in the active layer, a maximum power conversion efficiency (PCE) of 3.67% was obtained by blending 0.5 mg/mL GO:DDAB in the active layer, showing an efficiency increment of 13.35% as compared with that of the control device without doping GO:DDAB. The optimized OPVs with PTB7:PC71BM by adding GO:DDAB shows the PCE of 7.96%. Therefore, it paves a way to get high efficiency organic photovoltaic cells by directly blending surfactant-treated graphene oxide in organic solvent.

Enalapril maleate as a green accelerator for zinc phosphating coating on low-carbon steel

Weishan Wang,Yuqin Tian,Aojue Ke,Haowei Huang,Huifang Shen,Xinya Zhang 한국공업화학회 2023 Journal of Industrial and Engineering Chemistry Vol.120 No.-

In this study, enalapril maleate (EM), a green ingredient of an antihypertensive drug, was selected as anaccelerator for phosphate coating promoting on low-carbon steel. The scanning electron microscope(SEM), X-ray diffraction (XRD), 3D morphologies, coating weight, coating thickness and free acidity(FA) as well as total acidity (TA) were characterized to analyze the coating performance. Copper sulfatetitration, potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) wereperformed to evaluate corrosion resistance of phosphate coatings. The DFT computations were appliedto explore the phosphating promoting mechanism. The results show that the EM optimal concentrationis 1.6 g/L which lowers the operating temperature (form 80 ℃ to 40 ℃), generates the smoothest (Ra = 2. 85 lm), the heaviest (28.35 g/cm2) and the thinnest (21.6 lm) coating, and reduces the corrosion ratefrom 1.099 mpy of blank to 0.0246 mpy. The density functional theory (DFT) results confirm that EMadsorbs on low-carbon steel by electrophilic sites (N10) as well as nucleophilic sites (C10), forms nucleatedparticles preferentially and accelerates the growth of crystals. Therefore, EM is a green organic compoundwith high phosphating promotion efficiency which has potential application prospects inindustrial phosphating.

Background: There are no recommendations for specific suture materials in transtibial pullout repair of medial meniscus posterior root tears. This study aimed to evaluate the clinical outcomes of transtibial pullout repair of medial meniscus posterior root tears using ultrahigh-molecular-weight polyethylene sutures and suture tape. Methods: We retrospectively reviewed the data of 36 patients (27 women and 9 men, mean age 64.1 years) who had undergone transtibial pullout repair of medial meniscus posterior root tears between November 2018 and December 2019. Two groups of 18 patients each received either two different cord-like sutures or suture tape. Clinical parameters were assessed preoperatively and on second-look arthroscopy (mean postoperative period 12 months). The meniscal healing status was assessed using a previously published scoring system (ranging from 0 to 10), and the incidence rate of suture cut-out was assessed on second-look arthroscopy. Results: All clinical scores significantly improved in both groups, with no significant between-group differences on second-look arthroscopy. The arthroscopic meniscal healing scores significantly differed between sutures (mean 6.7 points) and suture tape (mean 7.4 points; p = 0.044). No significant between-group difference in the suture cutout rate was observed. Conclusions: This study found no significant differences in the clinical outcomes between ultrahigh-molecularweight polyethylene sutures and suture tape. Favorable clinical outcomes were obtained using both types of suture; however, the usefulness of suture tape appears to be limited.

Peng Guo,Zhaojie Wang,Hongyu Chen,Shaohui Ge,Chen Chen,Haowei Wang,Jinbao Zhang,Minglei Hua,Shuxian Wei,Xiaoqing Lu 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2019 NANO Vol.15 No.01

The increasing energy crisis promotes the study on novel electrode materials with high performance for supercapacitive storage and energy conversion. Transition metal phosphates have been reported as a potential candidate due to the unique coordination and corresponding electronic structure. Herein, we adopted a facile method for preparing NaCoPO4@C derived from a metal organic framework (MOF) as a bifunctional electrode. ZIF-67 was synthesized before a refluxing process with Na2HPO4 to form a precursor, which is transformed into the final product via calcination in different atmospheres. Specifically, the resultant NaCoPO4@C exhibits a high specific capacitance of 1178.7 F g -1 at a current density of 1 A g -1 for a supercapacitor. An asymmetric supercapacitor (ASC) assembled with active carbon displays a high capacitance of 163.7 F g -1 at 1 A g -1. In addition, as an oxygen evolution reaction (OER) catalyst, the NaCoPO4@C electrode requires only 299 mV to drive a current density of 10 mA cm -2. These results suggest that the rational design of MOF-derived NaCoPO4@C provides a variety of practical applications in electrochemical energy conversion and storage.
