The collision efficiency of small bubbles with large particles

Bubble–particle interactions play an important role in many technological processes, e.g., in flotation. Although mineral flotation involves fine particles, this work focuses on the interactions between a small bubble and larger spherical particle and determining their collision efficiency. Based on the theoretical and experimental work, a simple relation for estimating the collision efficiency is proposed. The calculated efficiencies are compared to a large set of experimental data and are found to be in excellent agreement.     

Forms of Collaboration and Project Delivery in Chinese Construction Markets: Probable Emergence of Strategic Alliances and Design/Build

Changes in regulations to allow foreign contractors to qualify as wholly foreign-owned “construction enterprises” came into effect in September 2002 as one of the steps taken by the Chinese government to honor its World Trade Organization commitments. Emerging markets have a significant impact on the strategic planning of contractors; based on an electronic survey covering foreign contractors, clients (foreign investors), and design institutes, the design/build procurement route in conjunction with strategic alliances has been found to enable foreign contractors to enter the Chinese marketplace. The writers present a strengths, weaknesses, opportunities, and threats (SWOT) analysis to inform readers where opportunities for development might be found and to warn of threats to entry. The research also found that mutual trust, synergistic strengths and complementarities, market demand for services, flexibility for both parties, and minimum change of top managers were ranked as the top five critical success factors for strategic alliances between foreign contractors and design institutes. Finally, medium-sized, state-owned, and large-sized design institutes were ranked as the first, second, and third preferences, respectively, for strategic partnering by foreign contractors.     

基于扩展的构件依赖关系图聚类的体系结构重构策略研究*

通过在软件体系结构层次实施软件重构,能够改善软件的质量、提高软件的易演化性。提出了扩展的构件依赖关系图的概念,将软件体系结构的逻辑依赖关系以及演化历史中蕴涵的演化依赖关系纳入到统一的表示中。进一步提出了基于扩展的构件依赖关系图聚类的体系结构重构策略,从而达到改善体系结构质量的目的。     

新形势下中国房地产股权融资的新选择——有限合伙制

股权融资是中国房地产业未来主要的融资模式.国际经验和研究表明,房地产有限合伙制要比公司制更有效地降低委托代理成本,防止道德风险,实现资金和专有性资产的有效结合.在当前形势下,房地产业的稳健发展对中国经济全面复苏具有非常重要的作用,因此需要中国房地产企业股权融资模式的创新.在房地产企业信贷融资面临越来越多限制的环境下,由于新<合伙企业法>的颁布实施以及中国社会存在巨大的资本投资需求,中国房地产企业采取有限合伙制进行股权融资具有一定的现实可行性.
