A Green Analytical Method Using Polyurethane Foam for The Extraction and Determination of Lauryl Ether Sulfate in Personal Care Hygiene Products

A green methodology was developed for the extraction and determination of lauryl ether sulfate in raw materials and commercial liquid soap and shower gel samples. The method avoids the use of organic solvents, offering a simple, cheap, and safe analysis. The methodology is based on the sorption of an ionic pair consisting of a cationic dye and an anionic surfactant onto polyurethane foam. The experimental variables were optimized by chemometry to obtain the conditions that maximized extraction of the ionic pair. Digital imaging and spectrophotometry were used for quantification in the linear concentration range from 10.0 to 100 mg L-1. The limits of detection and quantification were, respectively, 2.71 and 9.28 mg L-1 for digital imaging, and 1.74 and 5.83 mg L-1 for spectrophotometry. The methods showed good results when applied to commercial samples, with recoveries in the range 96.8-103%.

Adaptive Feature Classification Model for Detecting Lung Disorders

Clinical picture preparation is that the method and procedure acclimated make the photos of the physical body [organs] for clinical purposes (clinical methodology looking to uncover analyze or inspect ailment) or clinical sciences(including the investigation of ordinary life structures and physiology). The segment of biomedical imaging nearby Digital Imaging and Communications in Medicine [DICOM] gives the fundamental standard to scientists to acknowledge similarity and improve work process productivity between imaging frameworks and other data frameworks in social insurance conditions around the world. Here during this report, the ID of disease tissues is finished by Computer-aided diagnosis (CAD) and development of malignancy tumors [Benign and Malignant] in the human lung is examined and suspected obsessive district which will be influenced by this tissues on the grounds that the time advances would be anticipated.

The Objective Conditions Study and Optimization of Digital Imaging System on Color Measurement：Case with Jadeite

The application of digital imaging to color measurement is more and more extensive, which also provides new ideas for gemology. In this paper, the single-factor experiment method and orthogonal experiment design are used to study the influence parameters of the digital imaging system (DIS) on gem color measurement. Among them, the illuminance has the most significant impact on the measurement results, followed by the exposure time, and the change of the measurement distance has an insignificant impact on the results; through range analysis and analysis of variance, the most suitable measurement parameters for red jadeite are 1600lx, 12500ms, 25cm.

ILLUMINANCE DISTRIBUTION MEASUREMENT OF MUSEUM EXHIBITS USING DIGITAL IMAGING LUMINANCE METER

The method for estimating the illuminance distribution in the vertical plane of museum objects (paintings) using a digital imaging luminance meters (ILMD) is considered. In order to pass from the luminance distribution to the illuminance distribution, a screen with reflective properties close to diffuse (Lambert) reflection is used. The theoretical and experimental uncertainty estimation of the measurement method done.
