Purpose - The purpose of this paper is to develop a framework of total acquisition cost of overseas outsourcing/sourcing in manufacturing industry. This framework contains categorized cost items that may occur during the overseas outsourcing/sourcing process. The framework was tested by a case study to establish both its feasibility and usability. Design/methodology/approach - First, interviews were carried out with practitioners who have the experience of overseas outsourcing/sourcing in order to obtain inputs from industry. The framework was then built up based on combined inputs from literature and from practitioners. Finally, the framework was tested by a case study in a multinational high-tech manufacturer to establish both its feasibility and usability. Findings - A practical barrier for implementing this framework is shortage of information. The predictability of the cost items in the framework varies. How to deal with the trade off between accuracy and applicability is a problem needed to be solved in the future research. Originality/value - There are always limitations to the generalizations that can be made from just one case. However, despite these limitations, this case study is believed to have shown the general requirement of modeling the uncertainty and dealing with the dilemma between accuracy and applicability in practice. © Emerald Group Publishing Limited.

本文研究了在酸性CdSO_4+HTeO_2~+6HgCl_2 电解液中多晶富镉Hg_(1-x),Cd_(?),Te(x>0.5)的电沉积过程,实现了三种离子在同一电位下共沉积的技术。对在钛基底上沉积出的薄膜进行XRD,SEM和EDAX分析,结果表明薄膜为闪锌矿型的多晶结构,分布均匀连续。考察了(1—x)=0.09时多晶薄膜在多硫氧化还原电对液中的光电化学行为,光强为100mW/cm~2时,短路光电流I_(sc)=1.88mA/cm~2,开路光电压V_(oc)=0.25V,填充因子F·F=0.22。由光电化学光谱所确定出的禁带宽度E_g=1.26eV,Mott-schottky曲线给出了电极的平带电位φfb为—1.26V(vs.SCE),从而得到开路光电压V_(oc)可能达到的最大值为0.49V。因此,多晶富镉Hg_(1-x)Cd_xTe薄膜是一种很有潜力的光活性电极材料。

A Embrapa Monitoramento por Satélite, desde 1991, adaptou-se a esse novo cenário tecnológico e vem aprimorando, sempre que possível, seus recursos físicos e humanos a essa realidade. Justamente por estar acompanhando e aplicando essa tecnologia desde seu início, a Unidade possui um histórico de acontecimentos e desenvolvimento de infraestrutura, linguagens computacionais e metodologias que refletem exatamente a rapidez com a qual a Internet vem se desenvolvendo e a amplitude de aplicações que vem oferecendo. Este histórico é apresentado no trabalho, com o intuito de resgate e registro da experiência da equipe do Centro, nesta área específica do conhecimento humano, avaliando as transformações e adaptações de tecnologias e linguagens e sua importância como instrumento de comunicação direta com a sociedade.

In order to find a link between results obtained from a laboratory erosion tester and tests carried out on a pneumatic conveyor, a comparison has been made between weight loss from bends on an industrial-scale pneumatic conveyor and erosion rates obtained in a small centrifugal erosion tester, for the same materials. Identical test conditions have been applied to both experiments so that comparable test results have been obtained. The erosion rate of mild steel commonly used as the wall material of conveyor pipes and pipe bends was determined individually on both test rigs. A relationship between weight loss from the bends and erosion rate determined from the tester has been developed. A discussion based on the results and their applicability to the prediction of wear in pneumatic conveyors concludes the paper.
