Ni bueno, ni bonito, ni barato. El problema de la simplificación de la naturaleza

Modern society has lost its natural connection with the environment. Present agriculture methods and city planning around the world support this fact. Humanity has always simplified nature in order to control it but, far from this, we have contributed to enhance current environmental issues as air and water pollution, soil fertility loss, species extinction and climate change. Therefore, it may be reasonable to change our point of view of nature. By assuming that we are an inseparable part of nature and vice versa, we may achieve a true conservation of the richness of our planet. We must synthesise nature because every living being is a part of a bigger whole. We need to live the complexity of life. Nowadays, we have reached a turning point after which we must decide either changing our ways or sacrificing our future. Hopefully, a slight impulse is sometimes enough to change the course of History

Cross-platform, Public Domain Simulation Tools for Performing Parametric IAQ and Energy Analysis

As building design is being driven towards lower energy use, the relationship between indoor air quality (IAQ) and energy becomes more important due in large part to reduced building envelope leakage, which can lead to higher indoor pollutant levels. Simulation tools that can analyze building design measures that aim to improve IAQ and energy use are necessary for evaluating potential trade-offs involving such measures. This paper will present the use of CONTAM and EnergyPlus, coupled using co-simulation, to perform parametric analysis of IAQ and energy impacts. Both of these tools are available in the public domain and provide cross-platform methods to evaluate both IAQ and energy use. Applications and workflow using these tools and available building models will be presented, including various energy and IAQ related measures that can be addressed with them. In particular, we present a framework for addressing energy measures (envelope tightening, insulation, and mechanical ventilation) and IAQ-related parameters (indoor/outdoor sources, ventilation rate, and filtration) in multi-family housing and effects on occupant exposure via a cohesive simulation environment that minimizes inter-domain coupling issues

Quando um discurso geralmente valorizado não é bem‑ vindo: o caso da expressão da crença num mundo geral justo por um membro (fictício) da élite financeira

We aim to show that an idea that is generally valued (“just world”) when expressed by ordinary people becomes paradoxically a sign of immorality when expressed by the finance elite. Participants from Portugal and Spain read the fictitious case (inspired by real events) of “George M.”, a stereotypical member of the finance elite. Participants randomly read that the target had expressed the idea that the world is fair or unfair to people in general. Then, they indicated how immoral the target was and how much they wished him various outcomes. Comparing the target who expressed “the world is not just”, the one who expressed “the world is just” was judged as more immoral. Higher immoral judgements predicted higher wishes of negative outcomes. These results advise the elite against using moralizing discourses, which are likely to backfireinfo:eu-repo/semantics/publishedVersio

The Trainer Project: A New Simulator-Based Driver Training Curriculum

The purpose of the EU funded TRAINER project is to develop a new cost-effective Pan-European driver training curriculum, includingcomputer-based interactive multimedia and simulator technology. Thecurriculum will pay significant attention to higher order skills including riskawareness. For this purpose a number of scenarios were developed thataddresses the most important needs of learner drivers. These scenarios are usedin a PC-based interactive multimedia tool as well as in a driving simulator. Theinteractive multimedia tool allows training and assessment of higher cognitiveskills (i.e., strategic and manoeuvring tasks), familiarisation of novice driverswith the basic principles of driving, and contributing to a better understandingof (potential) risks. A low cost stationary driving simulator is used for acquiringskills in vehicle handling and negotiating common traffic situations (i.e.,manoeuvring and control tasks). In addition, a mean cost semi-dynamic drivingsimulator is developed for supporting the needs of specific driver cohorts, suchas novice drivers with enhanced knowledge problems and drivers in high-riskgroups. Application of such an advanced computer-based curriculum alsoimplies development of criteria to allow driving instructors to determinetraining progress. These criteria are based on a database of normative driverbehaviour. This paper mainly focuses on the description of the technical (softandhardware) requirements for both low-cost and mean-cost simulators

Ultraviolet observations of the Saturnian north aurora and polar haze distribution with the HST-FOC

Near simultaneous observations of the Saturnian H2 north ultraviolet aurora and the polar haze were made at 153 nm and 210 nm respectively with the Faint Object Camera on board the Hubble Space Telescope. The auroral observations cover a complete rotation of the planet and, when co-added, reveal the presence of an auroral emission near 80 deg N with a peak brightness of about 150 kR of total H2 emission. The maximum optical depth of the polar haze layer is found to be located approximately 5 deg equatorward of the auroral emission zone. The haze particles are presumably formed by hydrocarbon aerosols initiated by H2+ auroral production. In this case, the observed haze optical depth requires an efficiency of aerosol formation of about 6 percent, indicating that auroral production of hydrocarbon aerosols is a viable source of high-latitude haze

Kolb in de klas: vijf docenten in het hoger onderwijs onderzoeken de waarde van Kolbs leerstijlen voor hun eigen onderwijspraktijk

Deze bundel bevat de resultaten van vijf kortlopende onderzoeken door deelnemers aan de masteropleiding Teaching in Higher Education, allen docenten in het hoger onderwijs, naar de waarde van de leerstijlen van Kolb voor hun eigen lespraktijk. Uit de onderzoeken komt naar voren dat het onderwijsaanbod niet geheel bepaald wordt door de leerstijl van de docent, maar dat het zou kunnen zijn dat het wel deels hierdoor beïnvloed wordt. Ook zijn vier manieren geïdentificeerd waarop docenten rekening houden met individuele verschillen tussen studenten. Ten aanzien van het verrichten van dit type onderzoek blijkt een noodzaak om het vóórkomen van en voorkeuren voor bepaalde leerstijlen op verschillende manieren te meten en om zowel met kwalitatieve als kwantitatieve methoden te werken; daarbij kan de Chi-square goodness-of-fit test voor één groep, goede diensten bewijzen. Ook lijkt het dat aangetroffen verschillen in leerstijlen wel eens veroorzaakt zouden kunnen zijn tussen verschillen in wat en hoe men meet, en geen reflectie zijn van feitelijke verschillen in leerstijlen

Generation of parallel electric fields in the Jupiter-Io torus wake region

Infrared and ultraviolet images have established that auroral emissions at Jupiter caused by the electromagnetic interaction with Io not only produce a bright spot, but an emission trail that extends in longitude from Io's magnetic footprint. Electron acceleration that produces the bright spot is believed to be dominated by Alfvén waves whereas we argue that the trail or wake aurora results from quasi-static parallel electric fields associated with large-scale, field-aligned currents between the Io torus and Jupiter's ionosphere. These currents ultimately transfer angular momentum from Jupiter to the Io torus. We examine the generation and the impact of the quasi-static parallel electric fields in the Io trail aurora. A critical component to our analysis is a current-voltage relation that accounts for the low-density plasma along the magnetic flux tubes that connect the Io torus and Jupiter. This low-density region, ∼2 Rj from Jupiter's center, can significantly limit the field-aligned current, essentially acting as a "high-latitude current choke." Once parallel electric fields are introduced, the governing equations that couple Jupiter's ionosphere to the Io torus become nonlinear and, while the large-scale behavior is similar to that expected with no parallel electric field, there are substantial deviations on smaller scales. The solutions, bound by properties of the Io torus and Jupiter's ionosphere, indicate that the parallel potentials are on the order of 1 kV when constrained by peak energy fluxes of a few milliwatts per square meter. The parallel potentials that we predict are significantly lower than earlier reports

What do Eumerus Meigen larvae feed on? New immature stages of three species (Diptera: Syrphidae) breeding in different plants

The genus Eumerus Meigen 1822 (Diptera: Syrphidae) is widely distributed in the Old World, though recently introduced into America, and their larvae feed on decaying vegetal material and/or inside underground storage organs of many plants, sometimes generating economic losses as pests. However, little is known about Eumerus larval cycles and their interactions with host plants. Here, immatures of three Eumerus species from different continents are described, noting their feeding habits and host plants. Larvae of Eumerus figurans Walker 1859 were obtained from Hawaiian cultured ginger roots; puparium of Eumerus alpinus Rondani 1857 originated from larvae collected in Asphodelus ramosus L. in France; puparia of Eumerus superbus Shannon 1927 were reared from larvae found in two Zamiaceae species from Australia. Mitochondrial COI sequences served for diagnosing E. figurans larvae. Optical and scanning electron microscopy were used to describe body features, head skeletons, anterior spiracles, pupal spiracles, and posterior respiratory processes. Overall, E. alpinus resembles E. nudus Loew 1848 immatures. Eumerus superbus has a remarkable morphology among all described immatures of the genus, being the only Eumerus reported from gymnosperms. Head skeleton of E. figurans suggests this species is a filtering one. Present findings show that larvae of Eumerus can be separated at the species level and that this genus is polyphagous, feeding on a wide range of plant tissues and taxa, including commercial species. This study emphasizes immature stages and breeding sites as important means to understand species life cycles and the interactions with their host plants and ecosystems.This study is part of Gabriel J. Souba-Dols’ PhD thesis. His position at the University of Alicante (FPU-UA 2016), as well as that of Antonio Ricarte (Ref. UATAL05), are funded by the “Vicerrectorado de Investigación y Transferencia del Conocimiento.” Additionally, this research was partly funded by the Project PGC2018-095851-A-C65 of the Spanish Ministry of Science, Innovation and Universities

C9orf72 repeat expansions cause neurodegeneration in Drosophila through arginine-rich proteins

An expanded GGGGCC repeat in C9orf72 is the most common genetic cause of frontotemporal dementia and amyotrophic lateral sclerosis. A fundamental question is whether toxicity is driven by the repeat RNA itself and/or by dipeptide repeat proteins generated by repeat-associated, non-ATG translation. To address this question we developed in vitro and in vivo models to dissect repeat RNA and dipeptide repeat protein toxicity. Expression of pure repeats in Drosophila caused adult-onset neurodegeneration attributable to poly-(glycine-arginine) proteins. Thus, expanded repeats promoted neurodegeneration through neurotoxic proteins. Expression of individual dipeptide repeat proteins with a non-GGGGCC RNA sequence showed both poly-(glycine-arginine) and poly-(proline-arginine) proteins caused neurodegeneration. These findings are consistent with a dual toxicity mechanism, whereby both arginine-rich proteins and repeat RNA contribute to C9orf72-mediated neurodegeneration

Evaluation of the passive safety in cars adapted with steering control devices for disabled drivers

The purpose of this research is to analyse the influence of steering control devices for disabled people on passive safety. It is based on the advances made in the modelling and simulation of the driver position and in the suit verification test. The influence of these devices is studied through airbag deployment and/or its influence on driver safety. We characterise the different adaptations that are used in adapted cars that can be found mounted in vehicles in order to generate models that are verified by experimental test. A three-dimensional design software package was used to develop the model. The simulations were generated using a dynamic simulation program employing LS-DYNA finite elements. This program plots the geometry and assigns materials. The airbag is shaped, meshed and folded just as it is mounted in current vehicles. The thermodynamic model of expansion of gases is assigned, and the contact interfaces are defined. Static tests were carried out on the deployment of the airbag to contrast with and to validate the computational models and to measure the behaviour of the airbag when there are steering adaptations mounted in the vehicle. © 2011 Taylor & Francis.Masiá Vañó, J.; Eixerés Tomás, B.; Dols Ruiz, JF.
