Welding is an significant link in industrial production,and it is known as the"industrial tailor".However,welding fume,arc light,and metal spatter cause a harsh welding working environment,and the quality of welding has a decisive influence on product *** production capacity,difficult recruitment,and low profits have become drawbacks for the development of the welding *** traditional welding with robots can solve these drawbacks and increase the precision of *** robots are industrial robots engaged in welding and are mostly used in large-scale manufacturing fields such as automobile *** robots are divided into spot welding robots,arc welding robots and laser welding *** addition,body accuracy and control accuracy are the two main factors that affect the robot welding *** this case,the sensing technology of welding robot is also essential.

Laminarin oligosaccharides (LOSs) with a specific degree of polymerization prepared through the laminarin degradation via laminarinase present more significant nutritional functions and application values. Human intestinal bacteria are promising potential producers of novel carbohydrate-active enzymes with unique properties. Here， a novel glycoside hydrolase family 128 (GH128) laminarinase OUC-BsLam26 from the intestinal bacterium Bacteroides sp. CBA7301 was heterologously expressed and characterized. The recombinant OUC-BsLam26 with a molecular mass of 49.86 kDa exhibits highest activity (6.60 U/mg) at 45 ℃ and pH 6.0， which shows noticeable temperature and pH stability. The purified OUC-BsLam26 could degrade laminarin via an endo-type mode with the generation of laminaripentaose， laminaritetraose， laminaritriose， and laminaribiose， among them， laminaritetraose is the principal product， which accounts for 45.25% of the total products， which is significantly different from the reported GH128 laminarinases. The minimum recognition substrate of OUC-BsLam26 is laminarihexaose. Furthermore， OUC-BsLam26 also could catalyze the transglycosylation process with the production of some novel glycosides. Altogether， the intestinal bacterium Bacteroides sp. CBA7301 contains laminarinase with unique product composition and OUC-BsLam26 is a hopeful bio-catalyst with the potential to produce laminaritetraose and some novel glycosides.

椭圆墩式码头为一种较为新型的墩式码头结构形式,目前水运工程相关规范对大型椭圆墩式码头的波浪力计算等尚不完全适用。基于水运工程规范中墩柱波浪力计算理论,结合工程案例和试验数据进行对比研究。结果表明:1)对于大型椭圆墩式码头,小尺度桩体横向波浪力实测值小于计算值,大尺度墩体纵向波浪力实测值大于计算值。2)对于小尺度桩体,水运规范计算方法不能反映边墩与中墩的波浪力差异,边墩横向波浪力实测值略小于中墩。对于大尺度墩体,规范计算不能充分反映出边墩和中墩的纵向波浪力差异。3)对于重要工程,建议波浪力以物模试验结果为准。

Objective:To assess the feasibility of dose escalation guided by ^(18)F-deoxyglucose positron emission tomography/computer tomography(^(18)F-FDG PET/CT)for esophageal cancer(EC).Methods and materials:Ten random patients treated with definitive chemoradiotherapy and pre-therapeutic ^(18)FFDG PET/CT were included in this ***,a threshold of 50%of SUVmax was used to define the high FDG uptake region of the GTV(GTVPET).Three intensity-modulated radiation therapy(IMRT)plans were generated,delivering three dose levels to three different planning target volumes(PTVs).50.4 Gy delivered to PTV50.4 was defined on computed tomography(CT)as Plan50.4,63 Gy was delivered to PTV63 was defined as GTV plus a uniform margin of 0.5 cm as Plan63,and 70 Gy delivered to PTV70 was defined as GTVPET plus a 0.5 cm margin as Plan70.A dosimetric comparison was performed based on normal tissue complication probability(NTCP)for the lung and ***:Clinically acceptable dose escalation failed for 2 of 10 patients in Plan63 due to heart dose *** patient failed heart dose constraint for *** patients failed spinal cord constraint for *** patients failed lung dose constraints for both Plan63 and Plan70,two of which were even not suitable for Plan50.4 for the same *** modeling for lung showed increased risk for Plan63 and Plan70 compared to *** difference between Plan63 and Plan70 was *** modeling for heart showed an increased risk from 6.38%of Plan50.4 to 8.88%of Plan70(P=0.009)or 9.79%of Plan63(P=0.007).The risk of heart mortality was significantly higher for Plan63 than Plan70(P=0.047).Conclusions:Selective boosting of sub-volumes based on ^(18)F-FDG PET/CT is feasible way with a modest increase in the risk of cardiac and lung toxicities.
