Implementation of learning by doing methods in the graphical engineering field

Regarding the different options to approaches with excessively theoretical contents that are applied in teaching, there are several innovative learning strategies for active students’ involvement. According to (1) most of the business look for professional profiles in which applicants not only have an academic background but also good personal skills, such as initiative, undertaking, communication skills, commercial vision, and so on. This paper presents the experiments that aim to achieve the objectives and catching skills by the Learning by doing technique (2), through a contextualization of the subject “Container and Packaging” in the Industrial Design Degree. Moreover, a close relation between university and business is achieved. In this way students acquire the requirements demanded by the company. A particularization of an industrial design methodology proposed by the Technological Institute of Packaging, Transport and Logistics (ITENE, Valencia) has been implemented for the design of packaging and packaging (4). Besides using this method, students take on a project-based learning (PBL) work under the role of company. Then, they realize the redesign of the container of a manufactured product close to his residence province, i.e. Ron Montero Winery, Granada. This practice will not only look for improving the student's ability to research and solve problems, but also to manage the professional and personal relationships that occur within each work group. These situations are necessary in the training process since they will be to be fought daily in their future professional life.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tec

Polyphenolic Compounds, Antioxidant, and Cardioprotective Effects of Pomace Extracts from Fetească Neagră Cultivar

Grape pomace is a potential source of natural antioxidant agents. Phenolic compounds and antioxidant and cardioprotective properties of fresh and fermented pomace extracts obtained from Vitis vinifera L. red variety Fetească neagră grown in Romania in 2015 were investigated. Grape pomace extracts total phenolic index, total tannins, total anthocyanins, proanthocyanidins, flavan-3-ol monomers, stilbenes, and DPPH free radical scavenger were measured. The effect of a seven-day pretreatment with grape pomace extracts on the isoprenaline-induced infarct-like lesion in rats was assessed by ECG monitoring, serum levels of creatine kinase, aspartate transaminase, and alanine transaminase. Total serum oxidative status, total antioxidant response, oxidative stress index, malondialdehyde, total thiols, and nitric oxide have been also assessed. Higher phenolic content and antioxidant activity were found in fermented pomace extracts when compared to fresh pomace extracts. Pretreatment with grape pomace extracts significantly improved cardiac and oxidative stress parameters. In conclusion, Fetească neagră pomace extracts had a good in vitro antioxidant activity due to an important phenolic content. In vivo, the extracts had cardioprotective effects against isoprenaline-induced infarct-like lesion by reducing oxidative stress, fresh pomace extracts having a better effect

Investigación sobre la producción vitivinícola en el bajo valle del Ebro (ss. VII-I a. C.): un proyecto interdisciplinar de arqueología experimental

We present the results of an interdisciplinary project aimed at the experimental reproduction of wine making processes (production, storage, and conservation) according to historical-archaeological data from Iron Age (7th-1st centuries BC) north-eastern Iberia. The experiment has documented an annual cycle, from grape harvesting, production of must, its transformation into wine and the subsequent conservation of the resulting drink. In order to check its progress, its quality and suitability for consumption, the alcoholic degree, total acidity, pH, volatile acidity, colour, and potassium concentration were analysed and evaluated. In addition, quarterly wine tastings were conducted to assess its organoleptic quality and degree of taste acceptability. A basic microbiological control of the main yeasts and bacteria identified during the process was carried out, too. The results provide fundamental data on the stages of wine production process and preservation conditions, both of which are key to analysing the role of wine consumption in the social practices of Iron Age communities in the north-east of the Iberian Peninsula.Se presentan los resultados de un proyecto interdisciplinar que ha tenido como objetivo la reproducción experimental de los procesos de producción, almacenamiento y conservación del vino de acuerdo a los datos histórico-arqueológicos procedentes del nordeste peninsular durante la Edad del Hierro (ss. VII-I a. C.). El experimento ha documentado el ciclo anual, desde la recolección de la uva, la elaboración del mosto y su transformación en vino, hasta la posterior conservación de la bebida resultante. Con el fin de comprobar su evolución, calidad y aptitud para el consumo, se han analizado y valorado el grado alcohólico, la acidez total, el pH, la acidez volátil, el color y la concentración de potasio. Asimismo se han realizado catas trimestrales para determinar la calidad organoléptica y su grado de aceptabilidad gustativa. Paralelamente, se ha efectuado un control microbiológico básico de las principales levaduras y bacterias localizadas durante el proceso. Los resultados aportan datos relevantes sobre las fases del proceso productivo y las condiciones de conservación del vino, ambas claves para analizar el papel de su consumo en la práctica social de las comunidades de la Edad del Hierro del noreste peninsular

Relación entre el cansancio emocional de los estudiantes universitarios con su autoestima y satisfacción con los estudios

El trabajo que se presenta está enmarcado en la Red docente Cansancio emocional, autoestima y satisfacción con los estudios de los estudiantes universitarios, en la que participa profesorado de varios departamentos y diferentes universidades (Alicante, Elche, Murcia y Granada/campus Melilla). La competencia emocional que el estudiante tenga durante todo su proceso de aprendizaje puede ser un elemento de freno al estrés académico y a la actitud de estar quemado (burnout), teniendo como consecuencia una actitud positiva o negativa hacia los estudios y tareas que realiza. Este trabajo se plantea como objetivo analizar la relación entre el cansancio emocional, la autoestima y la satisfacción con los estudios del alumnado universitario. Estos aspectos se analizan en una muestra representativa de estudiantes de diferentes titulaciones y universidades. Los resultados nos permiten conocer la relación de variables emocionales con el grado de satisfacción con los estudios, aspectos que repercuten a lo largo de todo el proceso de aprendizaje de los estudiantes

The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment

The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourteenth from SDSS overall (making this, Data Release Fourteen or DR14). This release makes public data taken by SDSS-IV in its first two years of operation (July 2014-2016). Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey (eBOSS); the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data driven machine learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS website (www.sdss.org) has been updated for this release, and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020, and will be followed by SDSS-V.Comment: SDSS-IV collaboration alphabetical author data release paper. DR14 happened on 31st July 2017. 19 pages, 5 figures. Accepted by ApJS on 28th Nov 2017 (this is the "post-print" and "post-proofs" version; minor corrections only from v1, and most of errors found in proofs corrected

Black list and Alert list of the Aquatic Invasive Alien Species in the Iberian Peninsula: an action of the LIFE INVASAQUA

Resumen del trabajo presentado en VI Congreso Nacional sobre Especies Exóticas Invasoras y I Congreso Ibérico sobre EEI (EEI 2022) celebrado en Navarra del 20 al 23 de abril de 2022.One of the objectives of LIFE INVASQUA project is to develop tools that will be more efficient the Early Warning and Rapid Response (EWRR) framework for Invasive Alien Species in the Iberian Peninsula. Horizon scanning for high-risk IAS is basic in implementing measures to reduce new invasions, developing Alert lists, and to focus effort in the species already established, for instance making a Black list. We developed a trans national horizon scanning exercise focused on inland waters of Spain and Portugal in order to provide a prioritized lists (Black list and Alert list) of aquatic IAS that may pose a threat to aquatic ecosystems and socio economic sectors in the future. We followed a step approach of existing information about IAS (Plants, Freshwater Invertebrates, Estuarine Invertebrates and Vertebrates; 127 established taxa in Black list; 90 non established taxa in Alert list) combining with an expert scoring of prioritized taxa. IAS established in the Iberian aquatic system consistently highlighted as the worst included vertebrates (e.g. Cyprinus carpio, Gambusia holbrooki, Silurus glanis), freshwater and estuarine invertebrates (e.g. Procambarus clarkii, Dreissena polymorpha, Pacifastacus leniusculus, Ficopomatus enigmaticus, Callinectes sapidus, Corbicula fluminea) and plants (e.g. Eichhornia crassipes, Azolla filiculoides, Ludwigia grandiflora). Amongst taxa not yet established (Alert list), expert pointed to Perna viridis, Hydroides dirampha, Dreissena bugensis, Procambarus fallax f. virginallis, Perccottus glenii with higher risk of invasion, ecological and socioeconomic impacts. Over 20.6% of the taxa in the preliminary black list received no votes (no prioritization) by experts, 17.8% in the innitial alert list. Our horizon scanning approach is inclusive of all-taxa, prioritizes both established and emerging biological threats across trans-national scales, and considers not only the ecological impact, but also potential direct economic consequences as well as the manageability of invasive species.This work received funds from the LIFE Programme (LIFE17 GIE/ES/000515)

Sloan Digital Sky Survey IV: mapping the Milky Way, nearby galaxies, and the distant universe

We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is observing hundreds of thousands of Milky Way stars at high resolution and high signal-to-noise ratios in the near-infrared. The Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey is obtaining spatially resolved spectroscopy for thousands of nearby galaxies (median ). The extended Baryon Oscillation Spectroscopic Survey (eBOSS) is mapping the galaxy, quasar, and neutral gas distributions between and 3.5 to constrain cosmology using baryon acoustic oscillations, redshift space distortions, and the shape of the power spectrum. Within eBOSS, we are conducting two major subprograms: the SPectroscopic IDentification of eROSITA Sources (SPIDERS), investigating X-ray AGNs and galaxies in X-ray clusters, and the Time Domain Spectroscopic Survey (TDSS), obtaining spectra of variable sources. All programs use the 2.5 m Sloan Foundation Telescope at the Apache Point Observatory; observations there began in Summer 2014. APOGEE-2 also operates a second near-infrared spectrograph at the 2.5 m du Pont Telescope at Las Campanas Observatory, with observations beginning in early 2017. Observations at both facilities are scheduled to continue through 2020. In keeping with previous SDSS policy, SDSS-IV provides regularly scheduled public data releases; the first one, Data Release 13, was made available in 2016 July
