摘要： Micro-wire-cut electrode discharge machining (EDM) is an emerging manufacturing process in the field of micro-manufacturing to fabricate the complex profiles of micro-components. It is a complex process involving various process parameters such as pulse on time, pulse off time, wire speed, wire tension and current. In addition to micro-fabrication, this process can also be extended in the field of tool design and developments such as dies, moulds, precision manufacturing, contour cutting, etc., where complex shapes need to be generated with high-grade dimensional accuracy and surface finish. In this research work, an attempt is made to investigate the effect of process parameters on the output variables such as material removal rate (MRR), surface finish and the cutting width (kerf) of wire-cut EDM for duplex stainless steel (DSS). Scanning electron microscopy (SEM) has been used to capture the images of the kerf width, and the measurements are taken with the help of the welding expert system and software. An optimization technique (Taguchi method) has been employed to identify the optimum parameters of the micro-wire-cut EDM process for cutting 2205 grade duplex stainless steel. The effect of each control parameter on the performance measure is studied individually using the plots of signal to noise ratio.

摘要： This article relates to the concept of urban expansion reduction in limited areas, called "de-sprinkling districts", and methods of designation of their range, as well as modelling and management of their network. This concept was developed from research concluded in 2016, referring to 50 years of urban evolution in Italy, that investigated and diagnosed the forms of urban growth focusing on the Italian model. For this model, the authors of this paper proposed an alternative definition (urban sprinkling) with respect to the sprawl international standard. Certainly this urban model established in Italy during the mentioned years is due to an inefficient control of peripheral areas and new conurbations' development, both in forms and functions. The cause is to be searched for in the importance given to single towns' general plans and the minor role of strategic planning (province and region). The political and social assumption that urban development according to the extreme sprinkling model is no longer feasible is gaining ground. However, implementing de-sprinkling processes will not be easy. In this paper, criteria to create a decision support system (DSS) for administrators and municipalities is illustrated. These criteria aim at dealing, technically and politically, with sprinkling and planning medium-term containment.

关键词： genistein   inflammation   barrier   NF-kappa B   mice  

摘要： This study aimed to investigate the protective potential of genistein in dextran sulfate sodium (DSS)-induced colonic injury in vitro and in vivo models. The results showed that DSS exposure caused growth suppression, colonic injury, inflammation, and barrier dysfunction in mice. Dietary genistein alleviated DSS-caused colonic injury via reducing colonic weight, rectal bleeding, and diarrhea ratio. Meanwhile, genistein reduced colonic inflammatory response via downregulating cytokines expression and improved colonic permeability and barrier in DSS-challenged mice. In Caco-2 cells, genistein improved cell viability and cellular permeability and inhibited DSS-induced activation of TLR4/NF-kappa B signal. In conclusion, genistein alleviated DSS-caused colonic injury, inflammation, and gut dysfunction, which might be associated with the TLR4/NF-kappa B signal.

关键词： 京津冀   河北省商务英语人才  

摘要： 随着京津冀协同发展背景下河北经济的快速前进,商务英语人才必将供不应求。这种商务英语人才结构性缺余状况将会阻止我省经济发展,不利于京津冀协同发展。由于河北高等教育资源相对于京津地区处于"低谷地带",我省商务英语人才培养可以从以下两方面入手。一是政府部门推进京津冀教育的"协同与创新",把商务外语人才培养纳入省"十三五"规划予以前瞻性及通盘性考虑,京津冀政府、学校以及企业在基于共识的基础上突破传统范畴进行多角度、全方位的教育体制改革,深度协同合作,共赢互利,释放区域教育活力。二是改革高校商务英语人才培养模式,提高学生的实践能力,借鉴已有的先进经验,建设优秀的商务英语师资队伍,整合相关院系力量,建立商务英语人才教育培养基地。
