摘要：Advancing biotechnologies are revolutionizing not only health and medicine, but also many different sectors such as agriculture,energy, chemistry, and textiles. As synthetic biology is leveraged as a programmable platform for the creation and biodesign ofhigh-value biological medicines, foods, and commodities, the world is facing new territory in terms of ensuring the safety andsecurity of both novel and engineered biological organisms, as well as the biological and digital platforms in which they aredesigned. Biosecurity practices and policies have traditionally revolved around preventing the misuse of biological pathogens,primarily through controlling access to pathogens. The advent of biodesign capabilities, such as gene editors, gene synthesiscapabilities, and genetic engineering, requires a reevaluation of traditional biosecurity policies to mitigate risks associated withsuch engineering of biological entities. Here, features of “Biosecurity by Design” approaches are described, including theapplication of risk/benefit analysis and risk mitigation, post-COVID opportunities, and ethical global norms in the progressionof biodesign and growing bioeconomies.

摘要：This research evaluated the suitability of stone dust in the design and production of High Perfor-mance Concrete (HPC). HPC mix was designed, tested, costed and a comparison of concrete classes used in the market (Class 25, 30 and 35) done using Cost benefit Analysis (CBA). The cost benefit was analyzed using Internal Rate of Return (IRR) and Net Present Value (NPV). Laboratory tests established the properties concrete obtained from the design mix. Compressive strength, slump, and modulus of elasticity were tested and analyzed. Structural analysis using BS 8110 was done for a 10 storey office building to establish the structural member sizes. Members obtained from concrete Classes 25, 30, 35 and the new compressive strengths from HPC (Class 80) were obtained and compared. Analysis was done for structural members’ sizes and area freed as a result of de-signing with HPC as well as the steel reinforcement used. To justify the initial cost of HPC if ado- pted, the Cost benefit Analysis (CBA) was used to estimate increased costs versus income resulting from increased let table space created. The minimum class of concrete used in design was limited to Class 25 N/mm2. The research shows that it is possible to manufacture high strength concrete using locally available stone dust. The stone dust sampled from Mlolongo quarries achieved a characteristic strength of 86.7 N/mm2 at a water cement ratio of 0.32. With the results structural analysis of a 10 storey office structures with columns spaced at 8 meters center to center was de-signed using the four classes and results compared. There was a reduction of columns from 1.2 m wide to 0.65 m wide (over 45%) when concrete class changes from Class 25 to Class 80 creating over 3% of the total space area per floor. Cost benefit analysis using Net Present Value (NPV) and Internal Rate of Return (IRR) presented business case for the use of HPC. With Class 80, the IRR was at 3% and NPV being 8% of the total initial investment. The ste

摘要：梯级水电站联合优化运行对梯级总效益的发挥起着重要作用。以金沙江中游梯级水电站为例,建立以发电量最大为目标的优化调度模型,采用改进的POA算法进行计算,通过比较分析5个典型组合方案发现,联合优化运行包含的水电站数越多的调度方案,梯级系统的发电量相应越高,枯、汛期电量之比从1∶2.2增加到1∶1.1。提出基于Nash谈判的梯级水电站优化调度利益分配模型,模拟结果表明,该方法能激励各水电站参与联合调度的积极性,可使水能资源得到合理利用。
