Equipment-free pumping is a challenging problem and an active area of research in microfluidics, with applications for both laboratory and limited-resource settings. This paper describes the pumping lid method, a strategy to achieve equipment-free pumping by controlled generation of pressure. Pressure was generated using portable, lightweight, and disposable parts that can be integrated with ex...

According to the characteristics and application of 3D printing technology, problems be faced in process equipment maintenance rush repair are analyzed, advantages technology for summarized. Moreover, phenomenon analysis, finite element analysis optimization carried out combination with vulnerable parts large engineering equipment. To provide data samples based on FDM repair, explore potential ...

It is a common practice amongst programmers to construct parts of software programs by imitating parts of programs constructed by more experienced professionals. This “learn by example” approach can be applied at the design level by using patterns as sets of rules and recommendations to solve well-defined tasks within the development of computer-based systems. This paper describes the multi-lev...

Recent activities in the field of time and frequency metrology pursued at PTB are reviewed. Quasi-continuous operation of the cesium fountain frequency standard CSF1 enabled us to assess the performance of the older primary clocks CS1 and CS2 much better than previously possible. On average, the CSF1 and CS2 frequencies deviated by less than 5 parts in 10 during more than 2 years, which is well...

Rapid prototyping has become the primary means by which assembly engineers obtain prototype parts needed for systems design. Some predict that rapid prototyping will soon evolve into rapid manufacturing. Rather than having factories full of mass production equipment, factories will consist of hundreds of inexpensive layer-based fabrication machines that can economically produce custom parts. Ma...

Community EyE HEaltH Journal | Vol 23 iSSuE 73 | SEPtEmBEr 2010 In many lowand middle-income countries, it is often the people who are poor or with a disability – or both – who find it most challenging to access and pay for health care. When people do come to us for eye care, it is therefore vital that we provide quality services efficiently and effectively. To achieve this goal, we must ensure...

Problem statement: The “Energy Policy for Europe, EPE” and three environmental directives, proposed by the European Union (EU) in 2007, are stricter than those self-restrained by the enterprises. For this reason, the enterprises have to shortly improve their products for meeting with the strict requests setup by the EU. Consequently, it becomes even more important that the manufacturers evaluat...

The growing production of waste electrical and electronic equipment (WEEE) requires close loop management to protect the environment save resources. Repair reuse can extend product’s life span. However, debates on differences seen in resource consumption linked different ways repairing devices have received a limited amount attention. This article demonstrates quantification (cradle-to-gate) fi...
