This thesis explores the process of enhancing Community Entrepreneurship (CE) in rural areas through the lens of performativity. CE plays a critical role in supporting community welfare and economic growth (Langevang and Namatovu, 2019), particularly in rural environments where entrepreneurs deep...

Reading popular English literature of the last hundred years would lead one to believe that English food always has been bland. This is surprising, considering that England, during the early modern period (1500-1850 AD) established the East India Company, partially for the spice tr...

Gene therapy offers a promising strategy to deliver functional genes that can correct mutations causing genetic diseases. Among viral vectors, Adeno-associated virus (AAV) is commonly used as a safe and efficient vector for gene transfer of genetic material. Even though recombinant AAV ...

This thesis focuses on the analysis and assessment of the life cycle impacts of heat pipe-based heat exchangers (HPHE) in energy-intensive industries (EIIs), namely the steel, aluminium, and ceramics industries. These industries, vital to the European economy, are responsible for substantial ...

We have designed, developed, and integrated a comprehensive mathematical and numerical modelling framework for simulations of the complex physics and highly dynamic phenomena that occur across different length and time scale in the processes of sonochemistry and sonication of materials. The ...

The current research aimed to investigate the dominant heat transfer mechanisms during flow boiling of HFE-7100 in a single copper microchannel and use the data to assess predictive methods for the heat transfer coefficient. The single microchannel had a height of 0.811 mm, a ...

The role of lymphatic vessels in myocarditis is largely unknown, while it has been shown to play a key role in other inflammatory diseases. We aimed to investigate the role of lymphatic vessels in myocarditis using in vivo model induced with Theiler’s murine encephalomyelitis ...

摘要:超精密内圆磨床工件轴采用空气静压支承，其在超精密内圆磨削过程中与砂轮轴间的耦合效应往往会改变空气静压主 轴的回转精度并引入新的误差，对加工过程和工件精度有重要影响。提出了一种新的建模方法来研究空气静压主轴回转的耦 合效应及对超精密磨削过程的影响。将工件轴-砂轮轴组成的磨削系统作为一个整体加工闭环系统来进行设计分析。为了科学 地解析这一过程，以开发的超精密内圆磨床为研究对象，建立空气静压主轴双转子耦合模型，评估了空气静压轴承参数和超 精密内圆磨削过程对主轴动态响应的影响。并进一步分析耦合效应在亚微米-纳米尺度下对加工表面形貌的影响。研究发现， 空气静压轴承参数和动态磨削力对主轴振动有很大的影响，会降低表面加工质量，而最终的加工表面形貌由磨削系统和磨削 过程的耦合共同影响决定。研究最后展示了加工试验验证，用频谱分析方法得到了加工表面的圆度误差，试验与分析结果一 致，进一步验证了该方法的精密工程可靠性和应用性，该研究对于设计分析高精度空气静压主轴与科学的理解超精密内圆磨 削系统中空气静压主轴耦合效应具...
