| 1 | Biocompatibility evaluation of electrospun aligned poly(propylene carbonate) nanofibrous scaffolds with peripheral nerve tissues and cells in vitro显示文摘越过大差距的背景外部神经新生是临床上挑战性的。支架设计在神经织物工程起一个枢轴的作用。最近, nanofibrous 脚手架由于他们的物理性质的类似为房间附件和增长证明了合适的环境到自然细胞外的矩阵。(丙烯碳酸盐)(PPC ) Poly, nanofibrous 脚手架为脉管的织物工程被调查了。然而,没有报告为神经织物工程 PPC nanofibrous 脚手架存在。这研究试图评估潜在的角色排列并且是的随机的 PPC nanofibrous 脚手架为在神经织物工程的外部神经织物和房间的底层。排列的方法和随机的 PPC nanofibrous 脚手架被 electrospinning 制作,他们的化学描述用扫描电子显微镜学(SEM ) 被执行。从 Sprague-Dawley 老鼠的背面的根 ganglia (DRG ) 在 nanofibrous 底层上是有教养的 7 天了。从 DRG 的神经突长出和 Schwann 房间移植被观察并且确定了使用 immunocytochemistry 和 SEM。从老鼠导出的 Schwann 细胞臀部的神经在为 24 的 electrospun PPC 支架摘录液体是有教养的, 48, 72 个小时和 7 天。Schwann 房间的生存能力被 3- 评估[4,5-dimethyl (thiazol-2-yl )-2,5-diphenyl] tetrazolium 溴化物(MTT ) 试金。结果直径排列,随机的纤维在 800 nm 和 1200 nm 之间变化了,并且这些电影的厚度是近似 10-20 m。排列纤维电影的 Quantification 沿着纵的轴揭示了所有纤维的约 90% 排列。与随机的纤维电影,然而,纤维的排列通过所有角度箱是随机的。老鼠 DRG 将生物的活组织移植于培养基中培养在 PPC nanofiber 电影上被种多达 1 个星期。在排列纤维电影上,从 DRG 的神经突长出和 Schwann 房间移植的多数单向性地延长了,平行到排列 fibers.However 在随机的纤维电影上,神经突长出和 Schwann 房间移植随机被散布。从有教养的 DRG 的累积神经突长度的比较显示神经突在排列 PPC 电影上变得更快((缝的 2537.6ng 系统。 13 个盒子使用了 Hem-o-lok 夹钳缝术而不是传统的绑扎,并且肾的温暖的局部缺血的吝啬的时间是( 16.5 汳?睴?慤獹?汁?湡浩污?湵敤睲湥?虧湋T摲潩牧灡票愠摮栠敡潭祤慮業獣洠慥畳敲敭瑮??牡楤捡攠灸敲獳潩?景猠浥??慷?敤整浲湩摥戠?敲污琠浩?潰祬敭慲敳挠慨湩爠慥瑣潩?刨???愠摮圠獥整湲戠潬瑴湩?湡污獹獩?浉畭潮楨瑳'覕珮I慣?湡污獹獩眠獡甠敳?潴搠瑥牥業敮琠敨挠汥?潳牵散漠?敳慭愳椠?桴?敨牡?敒?瑬?獉灯潲整敲潮?湩畤散??搠祡?湡??搠祡???慲獴搠獩汰祡摥氠晥?敶瑮楲畣慬?楤慬楴湯? | WANG Yu ZHAO Zhe ZHAO Binx ZHAO Bin QI Hong-xu PENG Jiang ZHANG Li XU Wen-jing HU Ping LU Shi-bi | 2011 | Chinese Medical Journal2011，，15： | 8 |
| 2 | Lightweight Mutual Authentication Scheme for Protecting Identity in Insecure Environment显示文摘Many improved authentication solutions were put forward, on purpose of authenticating more quickly and securely.However, neither the overuse of hash function,or additional symmetric encryption, can truly increase the overall security. Instead,extra computation cost degraded the performance.They were still vulnerable to a variety of threats, such as smart card loss attack and impersonation attack, due to hidden loopholes and flaws. Even worse, user's identity can be parsed in insecure environment, even became traceable. Aiming to protect identity, a lightweight mutual authentication scheme is proposed. Redundant operations are removed,which make the verification process more explicit. It gains better performance with average cost compared to other similar schemes.Cryptanalysis shows the proposed scheme can resist common attacks and achieve user anonymity.Formal security is further verified by using the widely accepted Automated Validation of Internet Security Protocols and Applications(AVISPA) tool. | Xu Wu Jin Xu Binxing Fang | 2018 | China Communications2018，15，6： | 2 |
| 3 | Investigation of distribution uniformity of distributor for biogas slurry application based on CFD analysis显示文摘A horizontal distributor for biogas slurry application was proposed to explore the distribution performance through CFD analysis and verified by field test.The rheological properties of biogas slurry were analyzed at first,and key parameters were obtained for the next simulation.The effects of distribution modes,inlet direction,and outlets number on the velocity distribution of flow field and mass flow rate of the horizonal distributor were investigated by CFD simulations.Results of rheological properties indicated that biogas slurry was a non-Newtonian fluid and exhibited shear-thinning behavior.It can be well described by power-law model.The simulation results showed that the geometry of rotor,especially the block numbers was the main factor that determining the fluid movement and trajectory of distribution and output.The mode rotor 1 with two blocks reached the lowest variable coefficient of mass flow rate(4.49%),indicating a higher degree of uniformity.The upward inlet direction would obtain less dead zone,and the distributor with an even outlets number would possess more uniform distribution and less dead zone.The field test of the distributor with rotor 1,upward inlet direction,and 24 outlets has been carried on to verify the simulation results,the variable coefficient of mass flow was 13.06%,which was slightly higher than the simulation(9.23%),but it still within the range of requirement(<15%).The proposed model and the findings of this work are of guiding significance for the study of the utilization technology and equipment of liquid biogas residue. | Jingjing Fu Yongsheng Chen Binxing Xu Biao Ma Pengjun Wang Aibing Wu Mingjiang Chen | 2023 | International Journal of Agricultural and Biological Engineering2023，16，1： | 0 |
