    La col·lecció Visions d’un Món Desigual ofereix de manera compartida un coneixement crític, real i formatiu, i té la voluntat de sensibilitzar a les dones i els homes del futur més pròxim en el sentit que l’obtenció i l’administració dels recursos de la terra ha de respectar els valors humans i mediambientals reconeguts en els protocols internacionals, valors que garanteixen que els éssers humans i tots els éssers vius podran continuar habitant aquesta terra

    The Beach Crowding Index: A Tool for Assessing Social Carrying Capacity of Vulnerable Beaches

    No full text
    The aim of this paper is to introduce the Beach Crowding Index (BCI), a procedure to assess the social carrying capacity of vulnerable beaches. The study uses the PAOT (people at one time) approach and data gathered weekly throughout the bathing season regarding the number of beachgoers in 100m2cells of the beach to assess how many beachgoers it can comfortablyhold. The procedureis based on field work, interviewswith beachgoers and GIS analysis, andhas been tested on four beaches in protected areas on the Spanish Mediterranean coast. On a scale from 0 to 4, minimum scores throughout the bathing season are 0.7 and maximum 3.7, although results showed wide variationbetween the beaches, the section of the beach and the time of day. This study suggests that determining the location of beachgoers and collecting a long-term series of data is fundamental to assessing social carrying capacity, and thatthe BCI procedure can be used in a large number of applications

    A disposable, simple, fast and low-cost paper-based biosensor and its application to the determination of glucose in commercial orange juices

    A new biosensor for monitoring glucose levels in beverages is presented. The measurements are performed using potentiometric detection. Working electrodes are made using platinised paper as support and a biocompatible polymeric membrane made of a mixture of polyvinyl alcohol and chitosan containing glucose oxidase as the recognition layer. The system is based on the detection of the hydrogen peroxide generated by an enzymatic reaction performed in a highly sensitive, selective and simple way. The biosensors display suitable analytical performance (sensitivity −119.6 ± 6.4 mV/dec in the 0.03–1.0 mM range with a limit of detection of 0.02 mM). Determination of glucose in commercial orange juices is presented. These results were validated against conventional standard methods, showing good accuracy and fast analytical response. The methodology presented herein does not require complex samples treatment, offering an alternative to conventional methods, particularly for determinations performed with minimal expertise and without a laboratory infrastructure

    No full text
    Presentem aquí el segon volum de Recerca en Humanitats que, com el primer, recull els treballs que es van exposar a les Jornades del Doctorand organitzades pel Programa de Doctorat d’Estudis Humanístics de la Universitat Rovira i Virgili; en concret, a les III Jornades que es van dur a terme els dies 3 i 4 de maig de 2017. Són, en total, divuit capítols que, disposats per l’ordre alfabètic dels autors, constitueixen una nova mostra de la investigació que es fa en el camp de les Humanitats a la nostra Universitat així com a d’altres universitats de l’àmbit català. D’aquí que trobem estudis sobre diverses facetes de la història, la història de l’art, la literatura i la llengua que ens permeten donar a conèixer les tesis que s’estan elaborant actualment
