In recent years, the increasing use of synthetic dyes showed an increase of allergic contact dermatitis with tissues, food, pharmaceutical and cosmetic products. This paper describes a method for extracting quickly, efficiently and economically a natural dye the Nasunin, a purple anthocyanin. To assess the potential sensitizing effect on the skin, have been formulated and applied to the healthy...

In this paper, we propose a general framework for constructing IGA-suitable planar B-spline parameterizations from given complex CAD boundaries consisting of a set of B-spline curves. Instead of forming the computational domain by a simple boundary, planar domains with high genus and more complex boundary curves are considered. Firstly, some pre-processing operations including Bézier extraction...

High spatial resolution and fast capturing possibilities make 3D terrestrial laser scanners widely used in engineering applications and cultural heritage recording. Phase based laser scanners can measure distances to object surfaces with a precision in the order of a few millimeters at ranges between 1 and 80 m. However, the quality of a laser scanner end-product, like a 3D model, is influenced...

image completion is one of the subjects in image and video processing which deals with restoration of and filling in damaged regions of images using correct regions. exemplar-based image completion methods give more pleasant results than pixel-based approaches. in this paper, a new algorithm is proposed to find the most suitable patch in order to fill in the damaged parts. this patch selection ...

In the past few years several systems for object reconstruction based on the analysis of 2D images have been proposed. In order for such systems to be of practical use, the 3D data extraction process is expected to be fast and reliable. In this paper we propose a general approach for the reconstruction of complete objects based on a mesh fusion algorithm. Every surface patch is obtained as a de...

Background and Aims: A sensitive, accurate precise method has been developed for the determination of Capsaicin from pain patches by Gas chromatography Mass Spectrometry (GC-MS). irritant effects in high concentrations, so these can be minimized knowing amount present efficacy safety patches. Methods: was extracted using liquid-liquid extraction The Chromatographic separation performed 5% diphe...

Stereoacuity depends not only on the carrier frequency of Gabor stimuli, but also upon their size. To determine if this is also the case at large disparities, we have measured the upper limit for stereopsis, "Dmax", and assessed its dependence on carrier frequency and overall envelope size. The results differ markedly from the stereoacuity data. Dmax for stereopsis is primarily dependent on the...

Road crack detection is one of the important issues in field traffic safety and urban planning. Currently, road damage varies type scale, often has different sizes depths, making task more challenging. To address this problem, we propose a Cross-Attention-guided Feature Alignment Network (CAFANet) for extracting integrating multi-scale features damage. Firstly, use dual-branch visual encoder mo...

introduction: antibiotic supplements are regularly used in neuronal culture media to control contamination however, they can interfere with the neuronal excitability and affect electrophysiological properties. therefore, in this study, the effect of penicillin/streptomycin supplements on the spontaneous electrophysiological activity of hippocampal pyramidal neurons was examined. methods: electr...
