PURPOSE To investigate adrenomedullin-induced relaxation in isolated porcine ciliary arteries. METHODS In a myograph system (isometric force measurement), precontracted vessels ( approximately 0.1 micro M U46619; thromboxane A(2) analogue or approximately 10 nM endothelin-1) were exposed, in a cumulative manner, to increasing concentrations of adrenomedullin (1 nM to 1 micro M) in the presenc...

Optically pumped green lasing with an ultra low threshold has been achieved using an InGaN/GaN based micro-disk with an undercut structure on silicon substrates. The micro-disks with a diameter of around 1 μm were fabricated by means of a combination of a cost-effective silica micro-sphere approach, dry-etching and subsequent chemical etching. The combination of these techniques both minimises ...

The mixing of Newtonian and non-Newtonian fluids in a magnetic micro-mixer was studied numerically using  ferrofluid. The mixing process was performed in a three-dimensional steady-state micro-mixer. A magnetic source was mounted at the entrance of the micro-channel to oscillate the magnetic particles. The effects of electric current, inlet velocity, size of magnetic particles, and non-Newtonia...

In the paper, a novel three-port channel drop filter in two dimensional photonic crystals (2D PCs) with a wavelength-selective reflection micro-cavity is proposed. In the structure, two micro-cavities are used. One is used for a resonant tunneling-based channel drop filter. The other is used to realize wavelength-selective reflection feedback in the bus wave-guide, which consists of a point def...

The design and reliable operation of a two-phase micro-channel heat sink require a fundamental understanding of the complex transport phenomena associated with convective boiling in small, parallel coolant passages. This understanding is the primary goal of this paper. This goal is realized by exploring the following aspects of boiling in microchannels: hydrodynamic instability, two-phase flow ...

In this study, we described the fabrication method for microfluidic channels with circular-cross sectional geometries by reflow phenomenon. The photoresist reflow leads to shape change from rectangular to semicircular, and we optimized the reflow conditions by using positive photoresist to form the perfect cylindrical micropatterns. The resultant circular micropattern was used as a template for...
