This study focuses on determining the optimized thickness of an absorbing thin-film with embedded gold nanoantennas, for absorption enhancement. Gold paired-strips nanoantennas with small gaps have been proposed for light trapping because of the high localized electric field in the gap due to resonance. Paired-strips nanoantennas with small gaps produce higher effective absorption compared to s...

Ab.sfract-A network analogue method for calculation of the capacitance matrix of certain two-dimensional multiconductor systems is presented. The system is contained in a finite or infinite conducting rectangular boundary. An arbitrary number of parallel dielectric layers can be present, and the conductors consist of an arbitrary number of conducting strips at one or more of the dielectric inte...

The cornea is a transparent soft tissue covering the front of the eye. The biomechanical properties of the cornea have been commonly investigated by uniaxial tensile and inflation testing methods. The cornea like many other hydrated tissue swells when immersed in an ionic solution. Previous studies on hydrated tissues have shown that mechanical properties and hydration are closely related. The ...

Circumferential strips of pulmonary vessel wall were obtained at necropsy from the major arterial and venous branches at the lung hilum in patients aged 7-87 years. The extensibility of these strips was measured using the tension balance method of Harris et al. (British Heart Journal, 1965, 27, 651-659). The vessels were then bisected, and half of each strip was submitted for structural analysi...

The finite difference (FD) technique is used to investigate the air yap effect on the coupling between two planar microstrip lines. The strip lines are embedded between a dielectric substrate and a dielectric overlay. The air gap between the substrate and the overlay is present due to the thickness of the strips and~or the roughness o f the planar surfaces. A quasi-static FD technique based on ...

Abstract: Equal channel angular extrusion (ECAE) is a promising technique for production of ultra fine-grain (UFG) materials of few hundred nanometers size. In this research, the grain refinement of aluminium strip is accelerated by sandwiching it between two copper strips and then subjecting the three strips to ECAE process simultaneously. The loosely packed copper-aluminium-copper laminated b...

The main roles of the colonic mucosa are the absorption of water and electrolytes and the barrier function that preserves the integrity of the colonic wall. The mediators and mechanisms to accomplish these functions are under continuous investigation, but little attention has been paid to a possible control of colonic motility by the mucosa that would fine tune the relationship between absorpti...

OBJECTIVES The aim of this study was to develop mucoadhesive oral strips using hot-melt extrusion as a continuous manufacturing process. METHODS Powder blends of ketoconazole, a water-insoluble drug - either hydroxypropyl methylcellulose (HPMC) or soluplus (SOL), sorbitol (SRB) and magnesium aluminometasilicate (MAS) were extruded to manufacture thin strips with 0.5-mm thickness. The presence...

copper–silver bimetallic strips were produced by cold roll welding process and were treated by diffusion annealing in the temperature range 250–800 ?c. the interface bonding strength was determined by bending and peeling tests, resistance, conductivity and micro hardness profiles were determined and microstructure in the interface region was observed by optical microscope. electrical resistance...
