1. 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 sur

3. A COMPARISON OF HEDONIC AND UTILITARIAN DIGITAL PRODUCTS BASED ON CONSUMER EVALUATION AND TECHNOLOGY FRUSTRATION
Abstract This study explores how hedonic mobile applications (apps) compare to utilitarian apps in consumer evaluation. We posit that achieving a set of passionate consumers is a pre-cursor to product success in markets, whereas technology frustration is a negative hindrance to the product success. Also, we argue that technology frustration may act as a nega

6. Prediction of Topsoil Texture Through Regression Trees and Multiple Linear Regressions
ABSTRACT: Users of soil survey products are mostly interested in understanding how soil properties vary in space and time. The aim of digital soil mapping (DSM) is to represent the spatial variability of soil properties quantitatively to support decision-making. The goal of this study is to evaluate DSM techniques (Regression Trees - RT and Multiple Linear R

7. VARIATION OF WATER QUALITY ALONG A RIVER IN AGRICULTURAL WATERSHED WITH SUPPORT OF GEOGRAPHIC INFORMATION SYSTEMS AND MULTIVARIATE ANALYSIS
ABSTRACT This study demonstrates using remote sensing, geographic information systems and multivariate statistics to study water quality in an agricultural watershed. The monitoring of water quality in the watershed of Lontras's river in the southwestern region of the State of Paraná had been done in 2012 and 2013 with a multi-parameter probe in ten sites t

8. Species descriptions and digital environments: alternatives for accessibility of morphological data
Abstract Taxonomists' efforts throughout history provide significant amount of data that give support for establishing the specific identity of several groups of biological systems. In addition to identifying species, taxonomic research offers a wide range of biological information that can be used in other disciplines, e.g. evolution, ecology, integrated pe

9. Co-Creation of E-Services Enabled by the Digitalization of Physical Products
ABSTRACT: With the advent of digitalization, e-services are now enabled by embedded digital technologies in physical products such as vehicles, elevators, construction equipment. In spite of numerous instances of e-services enabled by the digitalization of physical products, little research has been carried out to investigate the characteristics of co-creati

10. Principal Component Analysis of Commercial Tannin Extracts Using Digital Images on Mobile Devices
Tannins from trees are an abundant renewable resource. The use of tannins is safe for the environment and human health, making it possible to develop environmentally friendly products, such as adhesives, flocculant agents for water treatment, flame retardant foams and anticorrosives. In this study, a methodology was developed for the identification of six co
