A survey dataset to evaluate the changes in mobility and transportation due to COVID-19 travel restrictions in Australia, Brazil, China, Ghana, India…
2020
COVID-19 pandemic has heavily impacted the global community. To curb the viral transmission, travel restrictions have been enforced across the world. The dataset documents the mobility disruptions and the modal shifts that have occurred as a consequence of the restrictive measures implemented in ten countries: Australia, Brazil, China, Ghana, India, Iran, Italy, Norway, South Africa and the United States. An online questionnaire was distributed during the period from the 11st to the 31st of May 2020, with a total of 9 394 respondents. The first part of the survey has characterized the frequency of use of all transport modes before and during the enforcement of the restrictions, while the se…
Analyzing risk management in Mediterranean Countries: The Syrian perspective
2012
During the recent years Mediterranean Partner Countries (MPCs) are facing major political, institutional, economic and societal changes. As a matter of fact, the agricultural sector has been interested by global trends and has become more and more exposed to world dynamics. The resulting exposure of MPCs’primary sectors to risks has called great attention on existing and feasible risk management tools, as well as on the role of public interventions. Our paper deepen on the risk management status quo in Syria and explore the possibility of new policy interventions. The analysis has been carried out through a field activity that allowed to understand the issue based on experts’ opinions. We p…
Crítica, sabotaje y subalternidad
2013
Este ensayo define un “nuevo” concepto de crítica denominado “crítica como sabotaje”, su necesidad en el contexto de la posglobalización y sus puntos de referencia. Para ello, introduce una definición de la textualidad como fuerza performativa real que modeliza la visión del mundo de los receptores y les incita a llevar a cabo actos y discursos. Asimismo, ilustra la “crítica como sabotaje” mediante unos breves ejemplos pertenecientes a diferentes registros semióticos.
Survey data on the consequences of COVID-19 and home confinement on the educational community and families in Spain
2021
[EN] This paper presents a dataset concerning the consequences of the COVID-19 pandemic and home confinement on the educational community and families, and the possibilities and opportunities for the return to schools. Data were collected through an online based cross-sectional survey between June 29, 2020 and July 12, 2020 in Spain. A total of 7,305 people who had children in their care during the COVID-19 crisis and the home-confinement period responded to the survey. The survey contained items concerning (i) socio-demographic information, (ii) conciliation of work, personal and family life during confinement, (iii) the impact of the pandemic on the respondent's family, and (iv) the respo…
FACS-based protocol to assess cytotoxicity and clonogenic potential of colorectal cancer stem cells using a Wnt/β-catenin signaling pathway reporter
2021
Summary Cancer stem cells (CSCs) play a key role in tumor initiation and progression. A real-time tool to evaluate the activation of CSC-specific signaling pathways is crucial for the study of this cancer cell subset. Here, we present a protocol to monitor, in vitro, the activation of Wnt/β-catenin signaling pathway, which is considered a functional biomarker for colorectal CSCs (CR-CSCs). This flow-cytometry-based protocol allows it to isolate CR-CSCs and to evaluate their cytotoxicity upon anti-tumor treatments. For complete details on the use and execution of this protocol, please refer to Di Franco et al. (2021).
Dataset of trace elements concentrations in snow samples collected in Jelgava City (Latvia) in December 2020
2021
Abstract The data set provided in this article consist of two repeated data sets of chemical elements concentrations in snow samples. The snow samples were collected in Jelgava city at December 15th with 5 day exposition time. Snow samples were collected in 59 monitoring points in Jelgava city and in one sample in rural area monitoring point as control. The collected snow samples were melted, acidified with HNO3 and analysed with ICP-MS. The samples were analysed Aluminium (Al), Silicon (Si), Chrome (Cr), Manganese (Mn), Iron (Fe), Nickel (Ni), Copper (Cu), Zinc (Zn), Arsenic (As), Molybdenum (Mo), Cadmium (Cd), Barium (Ba), Tungsten (W), Lead (Pb). The collected data are with fundamental s…
Data on physical and chemical characterization of wood combustion products derived at cogeneration power plants
2021
The data presented in this article are related to the research paper “Granulation of fly ash and biochar with organic lake sediments – A way to sustainable utilization of waste from bioenergy production” [1] in the context of waste material investigation and possible valorization instead of disposal. This article provides a comprehensive chemical and physical characterization of wood combustion products – fly ashes, bottom ashes, mixed ashes and biochar. Multiple analytical techniques and methodology were exploited to investigate the composition of wood combustion products, among them a loss on ignition, potentiometry, colorimetry, X-ray diffractometry, X-ray fluorescence spectrometry, indu…
El boletín Faraday (1928-29) y las relaciones entre historia y didáctica de las ciencias
2021
Faraday ha sido considerada una de las primeras publicaciones especializadas en didáctica e historia de la ciencia en España. Sin embargo, hasta la fecha su recuperación y estudio se revelaba pendiente. A través del análisis inédito de esta publicación de principios del siglo xx, se abordan las relaciones entre historia y didáctica de las ciencias desde una mirada diacrónica. Dicho análisis ha puesto de manifiesto cómo la didáctica de las ciencias contribuyó a impulsar la forja disciplinar de la historia de la ciencia y cómo esta última nutrió a la didáctica de las ciencias de un amplio sustrato metodológico y epistemológico. Este análisis también ha ofrecido varios elementos de reflexión p…
Difficulties in learning and teaching of Quantum Physics in High School
2013
Quantum Physics is a very important part of Physics. In this paper we analyze its teaching and learning in high school and we show the students’ main difficulties, particularly the ontological and epistemological. This article presents some reasoned arguments against traditional methods to teach Quantum Physics. Finally, a new approach to quantum Physics teaching is showed.
Supporting the Sustainable Energy Transition in the Canary Islands: Simulation and Optimization of Multiple Energy System Layouts and Economic Scenar…
2021
The Canary Islands have great potential for the implementation of sustainable energy systems due to its availability of natural resources. The archipelago is not connected to the mainland electricity grid and the current generation system is mainly based on traditional fossil fuel. Therefore, the islands strongly dependent on fuel importations, with high costs due to logistics. Furthermore, due to the inadequate coverage of residential heating and cooling needs, the per capita energy consumption is far below the Spanish national average. This occurrence has inspired an intense debate on the current development model of the Canary Archipelago, which has led to the implementation of actions a…
