The quality of pork meat is considerable importance as one the principal sources proteins. study proposed quantification myoglobin proportions (deoxymyoglobin, oxymyoglobin and metmyoglobin) in by exploring feasibility colorimetric-bionic sensor array combined with efficient variable selection algorithms. Specifically, a novel consists nine chemically responsive dyes was fabricated. Subsequentl...

Accurate information on the chemical nature of soil phosphorus is essential for understanding its bioavailability and fate in wetland ecosystems. Solution phosphorus-31 nuclear magnetic resonance (31P NMR) spectroscopy was used to assess the conventional colorimetric procedure for phosphorus speciation in alkaline extracts of organic soils from the Florida Everglades. Molybdate colorimetry mark...

A review of the human visual system, the CIE L*, a*, b* color space and its use in evaluating color-image quality, and digital image capture is presented, the goal of which is to provide background information for imaging professionals involved in creating digital-image databases for museums, archives, and libraries. Following this review, an analysis was performed to determine the effects of b...

Stickiness is the physical process of contaminated lint adhering to equipment. The degree of stickiness depends on chemical identity, quantity, and distribution of the sugars. The sugar in cotton fibers may be insect or plant derived. There are several methods for measuring cotton fibers stickiness. In this work, a colorimetric method was used for the measurements. In the method, honeydew was c...

We demonstrate a technique that uses microdroplets for culturing and selecting bacterial cultures in a model biotechnological application. We propose an assay for determination of ethanol concentration that provides increased dynamic range and is compatible with droplet microfluidic screening technologies. The assay comprises two enzymes—alcohol oxidase (AOX) and horseradish peroxidase (HRP)—an...

Spectrophotometric or colorimetric data are normally obtained in some type of photometric unit and must be dealt with mathematically to provide a final result expressedin concentration. Such mathematical operationsare time-consuming, require data transfer, and are subject to human error. A photometric systemhas been devised which can be adjusted to perform calculations automatically and provide...

In this work, we propose a method for three-dimensional (3D) reconstruction of wide crime scene, based on a Simultaneous Localization and Mapping (SLAM) approach. We used a Kinect V2 Time-of-Flight (TOF) RGB-D camera to provide colored dense point clouds at a 30 Hz frequency. This device is moved freely (6 degrees of freedom) during the scene exploration. The implemented SLAM solution aligns su...

An autonomous electrochemical sensor suitable for in situ silicate detection and monitoring marine environments, is presented without any use of liquid reagent. This paper shows characteristics figures merit using optimized chemical parameters. Under controlled laboratory conditions a 40 L tank, good calibration between 1.63 132.8 μmol L−1 was obtained. The limit the quantification obtained are...
