Since 2018,Turntide Technologies\'highly efficient electric motors-based on an updated version of an early 19th century design-have turned cooling fans in dairy barns across the United States;in addition,more than a dozen companies,including BMW and Amazon,have saved an estimated average of 64%on heating and cooling costs by retrofitting their rooftop heating,ven-tilation,and air conditioning(HVAC)systems with the company\'s“smart motor system”[1].Now,as announced in June and July 2021[1,2],the Sunnyvale,CA,USA-based company,backed by Bill Gates and Amazon,is shifting its focus to electric vehicles(EVs)after securing 225 million USD in funding and acquiring three startup firms-Hyperdrive Innovation,BorgWarner Gateshead,and Avid Technology-that make batteries,drivetrains,and EV controls,respectively.

近年来国家为促进现代职业教育发展,鼓励各高校承办、举办各种技能专业比赛,鼓励在校生参加技能竞赛、创业实训以提升技能水平.为了能够更加充分发挥竞赛的作用,本文分析当前会计实训课堂中所存在的问题,以键盘操作为实例,分析“竞赛常态化”和会计实训课相融合的利弊,以期更好地改进当前会计实训课堂教学.
创业就业能力提升是高等职业教育适应时代创新驱动发展的主要形式,也是以创业促进就业,提升大学生就业能力的一个重要方式.高职院校应结合学生成长规律,按照“真实学”“真实做”的思想,以课程教育模式改革为重点,形成课程混合式教学体系,培养兼有创新精神和创业能力的高素质应用型人才.
目的:观察电针对血管性痴呆大鼠学习记忆功能、海马CA1区神经元超微结构、活性氧(ROS)水平、NOD样受体蛋白3(NLRP3)及自噬相关蛋白表达的影响,探讨其部分作用机制.方法:雄性SD大鼠随机分为假手术组、模型组和电针组,每组10只.采用双侧颈总动脉永久性结扎法制备血管性痴呆大鼠模型.电针组选取“百会”“大椎”及双侧“肾俞”进行电针治疗,每次30 min,1次/d,连续4周.造模前、造模4周后及治疗后采用Morris水迷宫法评估各组大鼠学习记忆功能;治疗后用透射电镜观察海马CA1区神经元超微结构,DCF
生物陶瓷骨支架是继金属骨支架之后,较为理想的人工骨缺损修复材料.由于骨缺损形状各异,增材制造技术与生物陶瓷的结合,为骨支架的制备提供了个性化、定制化、成型复杂型体的可能.目前,陶瓷人工骨的增材制造技术展现出了巨大应用前景,但仍面临着力学强度不高、生物性功能单一的问题.为此,本文从提高骨支架的力学性能、拓展其生物性功能的角度出发,归纳分析了浆料/粉体体系、脱脂烧结工艺、材料复合、结构设计对支架力学性能的影响,从药物释放、治疗肿瘤两个方面总结了多生物功能支架的研究进展,并介绍了增材制造陶瓷骨支架在生物体内的研
