Blood typing is the most important test for both transfusion recipients and blood donors. In this paper, a low cost disposable blood typing integrated microfluidic biochip has been designed, fabricated and characterized. In the biochip, flow splitting microchannels, chaotic micromixers, reaction microchambers and detection microfilters are fully integrated. The loaded sample blood can be divide...

Abstract The superheating field H s mathvariant="normal">h of the Meissner state is thought to determine theoretical field-limit superconducting accelerator cavities. We inv...

Additive manufacturing is defined as a process based on the superposition of layers materials in order to obtain 3D parts; however, does not allow achieve adequate and necessary surface finishing. In addition, with development new superior properties, some them acquire high hardness strength, consequently decreasing their ability be machined. To overcome this shortcoming, technology assembling ...

The first and most obvious requirement of any below-knee prosthesis is to furnish a suitable extension of the stump to the ground in such a way as to provide adequate support for the body weight with as little involvement as possible of other parts of the residual anatomy. In the interest of appearance as well as of function, there is a need secondarily for some reasonably faithful simulation o...

For the development of a cost-effective melamine-modified urea formaldehyde resin (MUF), the study evaluated the effects of reaction pH and melamine content on resin properties and bond performance of the MUF resin adhesive systems. Eight resins, each with three replicates, were prepared in a factorial experiment that included two formulation variables: two reaction pHs (i.e., 4.5 and 8.0) and ...

As humans, we interact with our immediate environment through our senses — sight, sound, smell, taste and touch. Emulation of the senses by electronic means has long been a grand challenge of artificial intelligence and is pivotal in the development of accessible and natural interfaces between man and machine. Sight and sound are the simplest technologically, and the past decades have seen sign...
