The sensilla type, number and distribution in male and female adults of Carabus elysii Thomson, 1856 (Coleoptera: Carabidae) were studied using scanning electron microscopy. The results showed that there are seven categories and 12 types of sensilla in C. elysii adults: three types of S.Ch, three types of S.T, two types of S.B and one each of B.B, S.Co, S.Ca and S.Cam. There is no difference between male and female in the types of sensilla. Apart from the significant difference in the number and distribution of S.B.2, S.Co and S.Ca between male dorsal and ventral surfaces, there are no significant differences between male and female antennae. In general, the number of sensilla in females is larger than that in males. The results provide a basic reference for future ultrastructure, electrophysiological, and comparative behavioral studies of Carabus species.

Industrial sectors have resulted in a large amount of pollution. Environmental degradation problem requires more indepth research on relationships between different sectors’ economic output and pollutant emissions. This paper analyzes the relationship between industrial economy and ecology. On the basis of it, the driving factors of industrial sectors’ pollution emissions are analyzed. Firstly, decoupling elasticity of industrial sectors in Jiangsu province during 2004-2013 is analyzed by Tapio decoupling model. And then, the industrial sectors are classified into three types according to the different decoupling elasticity. Finally, the three types of industrial sectors’ driving factors of industrial solid waste output are decomposed by LMDI method. The results show that: industrial sectors in Jiangsu province are divided into strong decoupling sectors, weak decoupling sectors and expansive negative decoupling sectors; economic development significantly promotes the increase of industrial solid waste output of all sectors; technology improvement and industrial structure largely decrease industrial solid waste output of strong decoupling sectors and weak decoupling sectors; however, technology improvement accelerates industrial solid waste output of expansive negative decoupling sectors; the role of industrial structure factor changes from restraint to promotion of expansive negative decoupling sectors.
Steel Bridge Construction of Hong Kong–Zhuhai–Macao Bridge
Wen-bo Gao,Quan-ke Su,Jin-wen Zhang,Hong-bing Xie,Feng Wen,Fang Li,Ji-zhu Liu 한국강구조학회 2020 International Journal of Steel Structures Vol.20 No.5
The 55-km-long Hong Kong–Zhuhai–Macao Bridge (HZMB) is the world’s longest sea-crossing bridge, connecting Hong Kong with Zhuhai and Macao at the mouth of the Pearl River Estuary in China, comprising 22.9-km-long steel bridges. HZMB is the leading steel bridge in China, with top-level manufacturing and installation technology. This paper outlines the steel bridge construction experiences of HZMB to provide comparisons for the construction of other long sea-crossing steel bridges at home or abroad. The main considerations of construction constraints, scheme selection, structural and aesthetic design of HZMB are presented, and the following points related to new strategies in the steel bridge construction of HZMB are elaborated: (1) construction quality assurance, (2) automatic manufacturing technology, (3) large segment off shore installation, (4) eco-friendly paint (content limitation of volatile organic compounds) and new multifunctional inspection gantry, and (5) Guss Mastic Asphalt steel deck pavement system. The successful implementation of those strategies shows that the steel bridge construction of HZMB promotes improvement in the overall construction and management level of the Chinese bridge industry. The advanced experience of HZMB has opened up broad prospects for the design and construction of off shore bridge engineering in China.
Percutaneous catheter drainage for abscess after surgery

Percutaneous abscess drainage (PAD) has been proven to be a safe, effective, and widely used technique for the treatment of patients with abscesses after gastrointestinal surgery. The indications for PAD are expanding and most postoperative abscesses of the gastrointestinal tract are susceptible to PAD. PAD uses various imaging methods, including ultrasound, computed tomography, and several safe and reliable catheter insertion methods.
Structural Performance of Earthquake-damaged Beams in Fire
Bo Wen,Lu Zhang,Bo Wu,Ditao Niu 대한토목학회 2018 KSCE JOURNAL OF CIVIL ENGINEERING Vol.22 No.12
Post-Earthquake Fire (PEF) on frame structures usually leads to complicated and unpredictable thermal performance of damaged concrete members. In order to determine the structural performance of seismic-damaged Reinforced Concrete (RC) beams under PEF conditions, the RC frame structures are subjected to the shake table test. The test, used in conjunction with other existing seismic hazard data, demonstrates that the main geometric damage forms of RC beams after the earthquake are cracks and concrete spalling. Subsequently, calculating models of PEF RC beams are established in ABAQUS, and then the distribution of thermal field, hightemperature bearing capacity and reduction coefficient of seismic-damaged beams are proposed respectively. From experimental and numerical investigations, It can conclude that (a) the simplified numerical models are proven to accurately determine the fire performance of the damaged RC beams; (b) the thermal performance degradation caused by spalling is more severe than the degradation caused by cracking on PEF RC beams, which demonstrates that spalling takes a more important role than cracking; and (c) the prediction equation of the flexural bearing capacity reduction factor of PEF RC beams is feasible.

Gonadogenesis is a complicated process which involves multi-gene interactions. A rainbow trout (Oncorhynchus mykiss) gene spermatogenesis associated 4 (SPATA4) was cloned and characterized from adult rainbow trout testis. The cDNA sequence of rainbow trout SPATA4 contains an open reading frame of 1, 081 nucleatides encoding a putative protein of 259 amino acids. The putative protein from rainbow trout shares a 76.8% homology with zebrafish SPATA4. No trans-membrane regions or signal peptide were detected using bioinformatics methods. Subcellular localization analysis revealed that rainbow trout SPATA4 was a nuclear protein with highest possibility (39.1%). Multi-tissue reverse transcriptase PCR (RT-PCR) was performed to examine the distribution of rainbow trout SPATA4 in eleven organs of adult rainbow trout. The result demonstrated that this gene express specifically in testis and slight amount of expression was detected in ovary. Further analysis of SPATA4 characterization and function in rainbow trout may provide insight into the understanding of gonadogenesis process.
Observer-based Controller Design for A T-S Fuzzy System with Unknown Premise Variables
Wen-Bo Xie,He Li,Zhenhua Wang,Jian Zhang 제어·로봇·시스템학회 2019 International Journal of Control, Automation, and Vol.17 No.4
For the stabilization problem of T-S fuzzy system, a new observer-based controller design approachis proposed when premise variables are not accessible. With a fuzzy observer, the estimated states error system isdescribed as two parts: unknown premise variable caused terms and observer error terms. Consider the property thatthe norm of the unknown premise variable caused terms are under a Lipschitz condition constraint of observer error,an observer and controller errors augmented system is obtained. Then based on the Lyapunov function method, aseries of linear matrix inequality conditions are proposed to asymptotically stabilize the system, the observer gainmatrices are used to overcome the uncertainties caused by UPVs. Finally a simulation example is used to illustratethe effectiveness of the proposed method, comparisons with traditional method shows the conservatism reductioneffects.
