Infections frequently occur after skin injuries, posing a significant challenge in current clinical care. Frequently changing dressings to minimize wound infections and adhesions results in large amounts of medical waste. Therefore, developing environmentally friendly multifunctional dressings has considerable application and translational significance. This study aimed to prepare a wound dressing with favorable antimicrobial properties and biosafety by grafting a natural antimicrobial peptide, polylysine, onto a traditional cotton textile dressing. The cotton textile dressing offers excellent moisture absorption and softness, while polylysine provides excellent biocompatibility, a broad antimicrobial spectrum, and high stability. Furthermore, both materials are natural and biodegradable, making them ideal for environmentally friendly wound dressings.

水工钢闸门被广泛应用于我国西南地震高烈度地区。为了确保在脉动水流与地震荷载作用下的安全可靠运行,需要分析不同水头下闸门的抗震性能。采用ANSYS建立三峡大坝某深孔弧形工作闸门有限元模型,基于动力时程法,对其开展地震响应分析,研究闸门在无水、20 m、40 m、60 m和85 m水头下动水压力与地震荷载对闸门强度、刚度的耦合影响。结果表明:水头越高,闸门在有、无动水时的最大应力及主横梁径向位移差值越大,动水压力对闸门的地震响应影响越显著。该研究对于同类水工钢闸门的地震响应分析具有参考借鉴意义。

LIGHT [homologous to lymphotoxins, shows inducible expression, and competes with herpes simplex virus glycoprotein D for herpes virus entry mediator (HVEM/TR2)] is a new member of TNF superfamily. The HT-29 colon cancer cell line is the most sensitive to LIGHT-induced, IFNγ-mediated apoptosis among the cell lines we have examined so far. Besides downregulation of Bcl-XL, upregulation of Bak, and activation of both PARP [poly (ADP-ribose) polymerase] and DFF45 (DNA fragmentation factor), LIGHT-induced, IFNγ-mediated apoptosis of HT-29 cells involves extensive caspase activation. Caspase-8 and caspase-9 activation, as shown by their cleavages appeared as early as 24 h after treatment, whereas caspase-3 and caspase-7 activation, as shown by their cleavages occurred after 72 h of LIGHT treatment. Caspase-3 inhibitor Z-DEVD-FMK (benzyloxycarbonyl-Asp-Glu-Val-Asp-fluoromethylketone) and a broad range caspase inhibitor Z-VAD-FMK (benzyloxycarbonyl-Val-Ala-Asp fluoromethylketone) were able to block LIGHT-ind

Globally,sub-optimal use of nitrogen (N) fertiliser and elevated N irrigation groundwater have led to high leached nitrate (NO_(3)^(–)) losses from protected vegetable field *** fertiliser and irrigation management in different soil types is crucial to reduce future N loads from such *** present 4-year study examined leached N loads from lysimeter monitoring arrays set up across 18 protected vegetable system sites encompassing the dominant soil types of northern *** treatments applied at each field site were:1) a high N and high irrigation input treatment (HNHI);2) a low N but high irrigation input treatment (LNHI) and 3) a low N with low irrigation input treatment (LNLI).Results showed that the mean annual leached total nitrogen loads from the HNHI,LNHI and LNLI treatments were 325,294 and 257 kg N ha^(–1) in the fluvo-aquic soil,114,100 and 78 kg N ha^(–1) in the cinnamon soil and 79,68 and 57 kg N ha^(–1) in the black soil,*** N dissolved in irrigation water in the fluvo-aquic soil areas was 8.26-fold higher than in the cinnamon areas.A structural equation model showed that N fertiliser inputs and leaching water amounts explained 14.7 and 81.8%of the variation of leached N loads,***,reducing irrigation water by 21.5%decreased leached N loads by 20.9%,while reducing manure N and chemical N inputs by 22 and 25%decreased leached N loads by only 9.5%. This study highlights that protected vegetable fields dominated by fluvo-aquic soil need management to curtail leached N losses in northern China.

道德的进化分为生物进化和社会进化两个方面,生物进化是社会进化的基础,社会进化是生物进化的延伸和补充。道德的自然属性是道德个体通过生物进化获得的对事物的评价体系,道德的社会属性是道德个体通过社会进化获得的对事物的评价体系,这两种评价体系之间的关系是相互影响、相互依存的,并且在一定条件下可以相互转化。道德的社会属性是在实现自然属性的过程中产生的,没有道德的自然属性就没有道德的社会属性。道德的社会属性是对道德的自然属性的补充和超越。道德的社会属性和文化有着极为密切的关系,社会属性为不同文化的发展和交流提供了可能,同时也是产生文化冲突的基础。

工业机器人应该在尽可能短的周期内完成复杂的任务,以获得高生产率.确定机械手末端执行器访问多个任务点的最佳路径的问题与著名的旅行商问题(TSP)相似,但并不完全相同.为了使TSP适应机器人技术,需要优化的度量是时间而不是距离.另外,任意两点之间的行程时间受机械手构型的选择影响较大.因此,需要考虑运动学逆问题的多重解.逆运动学问题的求解是机器人控制的基础.许多传统的逆运动学问题的解决方法,如几何、迭代和代数方法,对冗余机器人来说是不够的.以此为出发点,基于遗传算法提出了一种新的编码方法来考虑逆运动学问题的多重解,方法适用于任何非冗余度的机械手.仿真实验结果显示,提出的方法能在一定的时间内快速找到最优解或近似最优解.且任何非冗余度机械手的多重配置很容易体现在遗传算法的编码中.
