    REVIEW

    A Review on Sources, Extractions and Analysis Methods of a Sustainable Biomaterial: Tannins

    Antonio Pizzi1,*, Marie-Pierre Laborie2,3, Zeki Candan4

    Journal of Renewable Materials, Vol.12, No.3, pp. 397-425, 2024, DOI:10.32604/jrm.2023.046074

    Abstract Condensed and hydrolysable tannins are non-toxic natural polyphenols that are a commercial commodity industrialized for tanning hides to obtain leather and for a growing number of other industrial applications mainly to substitute petroleum-based products. They are a definite class of sustainable materials of the forestry industry. They have been in operation for hundreds of years to manufacture leather and now for a growing number of applications in a variety of other industries, such as wood adhesives, metal coating, pharmaceutical/medical applications and several others. This review presents the main sources, either already or potentially commercial of More > Graphic Abstract

    Integrated Evolving Spiking Neural Network and Feature Extraction Methods for Scoliosis Classification

    Nurbaity Sabri1,2,*, Haza Nuzly Abdull Hamed1, Zaidah Ibrahim3, Kamalnizat Ibrahim4, Mohd Adham Isa1

    CMC-Computers, Materials & Continua, Vol.73, No.3, pp. 5559-5573, 2022, DOI:10.32604/cmc.2022.029221

    Abstract Adolescent Idiopathic Scoliosis (AIS) is a deformity of the spine that affects teenagers. The current method for detecting AIS is based on radiographic images which may increase the risk of cancer growth due to radiation. Photogrammetry is another alternative used to identify AIS by distinguishing the curves of the spine from the surface of a human’s back. Currently, detecting the curve of the spine is manually performed, making it a time-consuming task. To overcome this issue, it is crucial to develop a better model that automatically detects the curve of the spine and classify the… More >

    Comparison of four DNA extraction methods on various tissues and types of Sechium edule ( Jacq.) Sw.

    Galindo-Tovar ME, VS Gasperin-Sanatta, JA Alejandre-Rosas, OR Leyva-Ovalle, J Murguía-González, HE Lee-Espinosa, I L,ero-Torres

    Phyton-International Journal of Experimental Botany, Vol.83, pp. 307-310, 2014, DOI:10.32604/phyton.2014.83.307

    Abstract Sechium edule is an important crop in Southern Mexico and Central America, and México was the main producer, with 53% of the world production in 2012. This species presents high levels of morphological variation that have resulted in different types of varieties not clearly defined. However, morphological characteristics have not been sufficient to classify S. edule varieties, and it has been difficult to study the species genetic diversity. Because of it, there is a need to develop methods for studying the genetic diversity in S. edule. In this regard, the first step is to find a suitable DNA More >
