We present a simple device for multiplex quantitative enzyme-linked immunosorbant assays (ELISA) made from a novel melt-extruded microcapillary film (MCF) containing a parallel array of 200 μm capillaries along its length. To make ELISA devices different protein antigens or antibodies were immobilised inside individual microcapillaries within long reels of MCF extruded from fluorinated ethylene...

Braille is the most widely used system for written communication using tactile means. Automation of the Braille reading process will effectively enable the transcription and duplication of existing documents as well as their preservation. By converting a Braille document into electronic form, all the benefits of developments for the electronic form of printed documents can be enjoyed: easier tr...

Many of the newer X-ray machines are equipped with electronic means to provide dose-area product (DAP) information. For machines without that ability, an alternative method is to record radiation on a film that can handle a large amount of cumulative exposure. The use of GafChromic XR Type R film was investigated for this purpose by placing it at the X-ray tube assembly to record the radiation ...

bstract. We propose the use of the morphological pattern specrum, or pecstrum, as the base of a biometric shape-based hand ecognition system. The system receives an image of the right hand f a subject in an unconstrained pose, which is captured with a ommercial flatbed scanner. According to pecstrum property of inariance to translation and rotation, the system does not require the se of pegs fo...

Radiochromic film has become an important tool to verify dose distributions for intensity-modulated radiotherapy (IMRT) and quality assurance (QA) procedures. A new radiochromic film model, EBT3, has recently become available, whose composition and thickness of the sensitive layer are the same as those of previous EBT2 films. However, a matte polyester layer was added to EBT3 to prevent the for...

Dunes dominate the bed of sandy rivers and they respond to flow by changing shape size, modifying flow, sediment transport dynamics rivers. Our understanding ability predict dune adaptation, particularly growth decay, remain incomplete. Here, we investigate from an initial flatbed in a laboratory setting continuously mapping 3D topography using line laser scanner combined with camera. High-reso...

Abstract This study was aimed at evaluating the effect of freeze-drying and lacto-fermentation on texture parameters images sensory attributes beetroots. The samples were imaged using a flatbed scanner, textures from converted to color channels L, a, b, R, G, B, X, Y, Z computed. discrimination raw processed beetroots performed models based selected for each channel. quality determined related ...

This work describes a new, low-cost and simple-to-use method for the determination of free biothiols in biological fluids. The developed utilizes interaction with gold ions, previously anchored on micellar assemblies through electrostatic interactions hydrophilic headgroup cationic surfactant micelles. Specifically, reaction AuCl4− cetyltrimethyl ammonium bromide (CTAB) produces an intense oran...

A liquid droplet is fragmented by a sudden pressurized-gas blow, and the resulting droplets, adhered to the window of a flatbed scanner, are counted and sized by computerized means. The use of a scanner plus image recognition software enables us to automatically count and size up to tens of thousands of tiny droplets with a smallest detectable volume of approximately 0.02 nl . Upon varying the ...
