为深化工业用水量随社会经济发展变化规律的认识,提出“双层嵌套式”的结构分解分析(SDA)方法,量化了2002~2020年我国不同行业工业用水量变化驱动因素的影响.结果表明,以消费、投资和出口为代表的规模扩张因素是不同行业工业用水量增长的主要因素,其中人均消费扩张效应增长较快,且不同行业工业规模扩张的主要驱动因素存在明显差异,直接推动了工业结构变化.而工艺用水变动和水资源重复利用率变动是遏制工业用水量增长的主要因素,两者累计已完全抵消了工业规模扩张的正向效应,累计减少工业用水量112亿m^(3);但金属采选、冶炼加工及电力等能源加工行业的工艺用水变动负向效应偏小,仅依靠水资源重复利用率提升的工业用水效率提升潜力较小.因此,需要基于不同行业影响差异有针对性地强化工业节水管理,推动工业生产结构和消费结构转型升级,保持工业用水负增长态势.

目的胃癌(gC)严重影响人类的健康生活,研究表明其与丝氨酸/甘氨酸代谢密切相关。丝氨酸/甘氨酸代谢对于肿瘤细胞的增殖能力具有重要影响。本文的研究目的是探究丝氨酸/甘氨酸代谢能够影响胃癌细胞增殖能力的分子机制。方法本文通过一种基于随机和非梯度系统的势能景观所建立的大型代谢网络动力学建模方法,构建了一个稳定的胃癌细胞代谢动力学模型。基于对模型的调控,定量分析丝氨酸/甘氨酸代谢影响胃癌细胞增殖的动力学机制。对一般代谢网络动力学方程添加随机噪声,通过随机动力学分解得到代谢网络参数空间的李雅普诺夫(Lyapunov)函数。进一步减少与随机波动相关的Lyapunov函数变化,从而得到稳定的代谢网络。结果在动力学参数不足的情况下,成功构建了胃癌细胞代谢网络的动力学模型。当胞外丝氨酸可用时,模型优先消耗丝氨酸;当甘氨酸生成丝氨酸的速率增加时,模型显著上调生成S-腺苷甲硫氨酸(SAM)和S-腺苷同型半胱氨酸(SAH)的稳态通量。结论本文证明了胃癌细胞对于丝氨酸的优先摄取以及丝氨酸/甘氨酸转化速率对SAM生成的重要作用,其可能通过调节细胞甲基化进程影响胃癌细胞的增殖能力,为靶向丝氨酸/甘氨酸代谢的癌症治疗提供了新的思路和方向。

人类与动物的交互合作自古以来就有着悠久的历史,伴随着智能芯片、可穿戴设备和机器算法的快速发展,智慧动物与电子科技的交互成为了现实。如今,人类可以借助电子系统与动物进行沟通、感知和控制。这类电子设备的目标在于实现以动物为中心的工作模式,从而提升人类对动物的理解,最终促进动物智能和创造力的发展。本文将中型、大型动物作为研究对象,以发展其能力增强为目标,提出了“智慧动物增强系统”的构想。该构想用以描述这类装置的特性,并对现有的动物与计算机接口解决方案进行了全面综述。总的来说,智慧动物增强系统主要分为植入式和非植入式两类,均由接口平台、感知与解读、控制与指示三部分构成,并通过不同层次的增强系统和架构模式,从而实现人与动物的智慧交互。尽管已有的智慧动物增强系统仍然缺乏完整独立的交互系统架构,但在未来的发展中,智慧动物增强系统具备良好的前景和发展空间,不仅可以用于替代尖端设备和运输设备,还有望通过智慧共联实现跨物种的信息交互。同时,智慧动物增强系统可以促进人与动物的双向交互,对动物伦理和生态保护的发展也将产生重要的推动作用。更为重要的是,基于动物主体的交互模型开发能够为设计人机交互系统提供可借鉴的研究经验,从而有助于更高效地推进人机结合宏伟目标的早日实现。

Kinetic Model of Fixed Bed Reactor with Immobilized Microorganisms for Removing Low-Concentration SO_2

引用

Journal of Natural gas Chemistry 2007年第1期16卷 86-91页

作者： bing Huang YanyanWang Shiling Zhang Yong ao Faculty of Environmental Science ＆ Engincering Kunming University of Science and Technology Kunming 650093 Yunnan China Faculty of Science Kunming University of Science and Technology Kunming 650093 Yunnan China

On the basis of the analysis of the process of treating low concentrations of sulfur dioxide （SO2） gas in a fixed bed reactor, a kinetic model is proposed for this process after taking into consideration the effects of internal diffusion, cell concentration, and production yield of microorganisms but ignoring the effect of external diffusion. The results obtained from the model simulation show that this model can indicate the influence of the process factors, Cin, η μmax, Cx, A, h, Kin, and Q, on the removal of SO2 and that the prediction of the results by this model is also satisfactory. This kinetic model can also provide some very important indications regarding the preparation of immobilized microorganisms, selection and domestication of proper species of microorganisms, as well as the design of bioreactors.
