L’integrazione fra le esigenze di sicurezza strutturale ed efficienza energetica costituisce l’obiettivo di molteplici ricerche e innovazioni sull’involucro edilizio. nel campo dell’architettura storica, questo connubio appare particolarmente interessante per le murature, delle quali non di rado è complesso caratterizzare in modo affidabile sia le prestazioni meccaniche sia quelle termiche e igrometriche. nell’ambito strutturale come in quello energetico, una descrizione adeguata di tali caratteristiche impone una conoscenza approfondita di materiali e tecniche costruttive locali. in entrambi i campi, peraltro, le esigenze della conservazione incidono sulle possibilità di accurate indagini …
Sicily: a geological laboratory
2018
“Geologists at risk of extinction”: this is the opening sentence of an article of March 29, 2016 of “Il Sole 24ORE”, (1) that fits well the difficult situation that this professional category is experiencing in recent years. It has been witnessed, in fact, a strong reduction in the educational offer in both the school and university system, with the number of Departments in Earth Sciences dropped from 29 to 8, accompanied by a progressive reduction in enrollment and graduates, from 1140 in 2002 to 586 in 2008 (2). Numbers that make you think, especially if contextualized to the Italian territory, widely characterized by the hydrogeological, seismic and volcanological risk, in whose preventi…
Polyhydroxyalkanoates from mixed microbial culture: Production and extraction through green methods
2018
Large scale polyhydroxyalkanoates (PHA) production is limited by high production costs compared to that of petroleum-based plastics. Two key factors can be pin down to reduce costs: i) the use of mixed microbial cultures (MMC) instead of pure cultures and ii) the application of cheap and environmental friendly recovery technologies. In this work, the MMC biomass with PHA-accumulating capacity was selected in a sequencing batch reactor fed with a synthetic effluent emulating a fermented oil mill wastewater. The biomass was harvested and transferred to an accumulation reactor, where PHA contents up to 54% of the dry cell weight were obtained, using a mixture of acetic and propionic acids. A c…

València, capital de la infància evacuada
2018
En el primer periodo de la guerra civil, conforme las tropas sublevadas se aproximaban a Madrid en el otoño de 1936, las fuerzas que apoyaban a la República primero y las autoridades del Ministerio de Educación después, organizaron la evacuación de miles de niños y niñas a la retaguardia, en espacial a la costa levantina. Diversas localidades de Castellón, Valencia y Alicante, entre otros lugares. Para atender esa iniciativa se organizó una estructura administrativa dependiente del departamento de educación y las autoridades intentaron generalizar un sistema de colonia colectiva, aunque las promovidas por los grupos libertarios siempre defendieron su autonomía. En el primer periodo de la gu…

Development of atmospheric correction algorithms for very high spectral and spatial resolution images: application to SEOSAT and the FLEX/Sentinel-3 …
2018
Advanced high spectral and spatial resolution imager spectrometers on board new generation of Earth Observation missions bring new exciting opportunities to the remote sensing scientific community. However, this progress goes hand in hand with new challenges. The exploitation of data acquired from these family of advanced instruments requires new processing algorithms able to deal with these particularities. As part of this evolution, atmospheric correction algorithms - a mandatory processing step applied prior to the Earth surface reflectance data exploitation - must be adapted or reformulated, thereby paying special attention to how atmospheric effects disturb the acquired signal in the s…

La expresión de la ironía en la conversación. Estudio fonopragmático en un corpus de habla semiespontánea
2018
El título de esta tesis da cuenta del ámbito de actuación en el que se inserta esta investigación, la Fonopragmática. Más específicamente, este trabajo de tesis se centra en el análisis y el estudio de los indicadores acústico-melódicos de la ironía verbal en la conversación espontánea, y en contexto, principalmente. En este sentido, la carencia de trabajos dedicados al estudio de la diversidad fónica como desencadenante de funciones pragmático-irónicas concretas, nos ha obligado a seguir indagando sobre la descripción analítica de un tono de voz irónico como parte de un proceso interpretativo metarrepresentacional complejo (Haverkate, 1985; Alba-Juez, 1995; Attardo, 2003; Bryant y Fox Tree…

Estudio descriptivo y experimental del bloqueo del nervio tibial. Eficacia anestésica de la técnica retromaleolar y supramaleolar.
2018
INTRODUCCIÓN De los cinco troncos nerviosos que inervan el pie, el nervio tibial es el que presenta mayor dificultad para su bloqueo anestésico. Esta dificultad intrínseca del bloqueo selectivo del nervio tibial, está íntimamente relacionada con la localización del tronco nervioso en un plano más profundo, asociada a las características morfológicas del pie. A estos dos factores se les debe sumar el hecho de que el nervio tibial se ramifica distalmente en el nervio calcáneo, el nervio plantar interno y el nervio plantar externo. El interés especial por alcanzar un bloqueo efectivo del nervio tibial se debe a que el territorio que inerva este nervio se ve comprometido tanto en el caso de cir…
Variation of student engagement between different algebra tasks
2018
In this study, we analyse how 7th grade students’ engagement during small group work differed in two consecutive algebra lessons: in the first lesson students solved equa-tions and in the second lesson they created equations for other small groups to solve. Data was collected by videorecording the work of two groups in both lessons. Through directed content analysis, categories indicating student engagement were formed based on previous research and refined during analysis. The analysis revealed a change from individual engagement to collaborative engagement between lessons and an increase in many passive students’ engagement. Task characteristics which may affect the type and amount of eng…

Ius facit populum. Sul rapporto tra diritto e popolo nel Medioevo rileggendo Walter Ullmann
2018
In 1961, Walter Ullmann studied the characteristics of Politics and Government in the Middle Ages and he theorized two different models of power and law: the Ascending and Descending Themes of Government. In the same years, Francesco Calasso encouraged a renewal of Legal History and he developed the system of ius commune. Going through the famous theory proposed by Ullmann in Principles of Government and Politics in the Middle Ages, this paper aims at analyzing the concept of power during the period of ius commune and connecting these observations with the Calasso’s lesson.
On the gonality and the slope of a fibered surface
2018
Abstract Let f : X → B be a locally non-trivial relatively minimal fibration of curves of genus g ≥ 2 . We obtain a lower bound of the slope λ ( f ) increasing with the gonality of the general fiber of f. In particular, we show that λ ( f ) ≥ 4 provided that f is non-hyperelliptic and g ≥ 16 .

Mixing and ageing in the polar lower stratosphere in winter 2015–2016
2018
We present data from winter 2015–2016, which were measured during the POLSTRACC (The Polar Stratosphere in a Changing Climate) aircraft campaign between December 2015 and March 2016 in the Arctic upper troposphere and lower stratosphere (UTLS). The focus of this work is on the role of transport and mixing between aged and potentially chemically processed air masses from the stratosphere which have midlatitude and low-latitude air mass fractions with small transit times originating at the tropical lower stratosphere. By combining measurements of CO, N2O and SF6 we estimate the evolution of the relative contributions of transport and mixing to the UTLS composition over the course of the winte…
The Underestimated Significance of Conditioning in Placebo Hypoalgesia and Nocebo Hyperalgesia
2018
Placebo and nocebo effects are intriguing phenomena in pain perception with important implications for clinical research and practice because they can alleviate or increase pain. According to current theoretical accounts, these effects can be shaped by verbal suggestions, social observational learning, and classical conditioning and are necessarily mediated by explicit expectation. In this review, we focus on the contribution of conditioning in the induction of placebo hypoalgesia and nocebo hyperalgesia and present accumulating evidence that conditioning independent from explicit expectation can cause these effects. Especially studies using subliminal stimulus presentation and implicit con…
Virtual Reality and Games
2018
The concept of Virtual Reality (VR) dates back to around 1930, where different technologies and concepts arise. For instance, in 1929 Edward Link created the Link Trainer (further patented in 1931), reported to be the first example of a commercial flight simulator, being entirely electromechanical. Also, in the 1930s, the visionary, science fiction writer Stanley G. Weinbaum brings a story (Pygmalion’s Spectacles) that introduces the early idea of a pair of goggles that makes the wearer experience a fictional world through holograms, smell, taste, and touch. Weinbaum describes uncanny experiences for those wearing the goggles, aligned with the modern experiences of VR. It is in the mid 1950…
Detection of Fibroblast Growth Factor Receptor 1 (FGFR1) Transactivation by Muscarinic Acetylcholine Receptors (mAChRs) in Primary Neuronal Hippocamp…
2018
In addition to their canonical intracellular signals involved in the regulation of neuronal plasticity, G-protein coupled receptors can also rapidly transactivate tyrosine kinase receptors and their downstream intracellular signaling in absence of specific ligands. Here we describe our protocol for dissociating and maintaining hippocampal primary neurons in high- and low-density culture, followed by a description of methods employed to evaluate neurite outgrowth and protein phosphorylation associated with fibroblast growth factor receptor 1 transactivation by muscarinic acetylcholine receptors. Our goal was to provide the reader with detailed protocols of the abovementioned techniques and t…
The rank of random regular digraphs of constant degree
2018
Abstract Let d be a (large) integer. Given n ≥ 2 d , let A n be the adjacency matrix of a random directed d -regular graph on n vertices, with the uniform distribution. We show that the rank of A n is at least n − 1 with probability going to one as n grows to infinity. The proof combines the well known method of simple switchings and a recent result of the authors on delocalization of eigenvectors of A n .
Model order effects on ICA of resting-state complex-valued fMRI data : application to schizophrenia
2018
Abstract Background Component splitting at higher model orders is a widely accepted finding for independent component analysis (ICA) of functional magnetic resonance imaging (fMRI) data. However, our recent study found that intact components occurred with subcomponents at higher model orders. New method This study investigated model order effects on ICA of resting-state complex-valued fMRI data from 82 subjects, which included 40 healthy controls (HCs) and 42 schizophrenia patients. In addition, we explored underlying causes for distinct component splitting between complex-valued data and magnitude-only data by examining model order effects on ICA of phase fMRI data. A best run selection me…
Essential oil of Citrus lumia Risso: Phytochemical profile, antioxidant properties and activity on the central nervous system
2018
Citrus lumia Risso Essential oil Antioxidant properties Anti-cholinesterase activity Cytotoxicity Neuroactive effects 1. Introduction Plants that produce essential oils (EOs) represent a large part of natural flora and an important resource in various fields such as pharmaceutical, food and cosmetic industries, due to their flavor, fra- grance and biological activity (Swamy et al., 2016). EOs play a pivotal role in the growth and colonization of plants, giving color and scent to reproductive organs, attracting pollinators, favoring seed dispersion (Sharifi-Rad et al., 2017), and defending the plant against abiotic (light, temperature, etc.) and biotics (herbivores, harmful insects and pa- t…

Theology and the public arena from a Polish point of view
2018
Jednym z ważnych aktualnych problemów teologicznych jest miejsce teologii w przestrzeni publicznej. Wiążą się z tym pytania o doświadczenia i problemy, ale także możliwości i wyzwania, które mają dość mocne zabarwienie kontekstualne. Niniejszy artykuł przedstawia tę problematykę z perspektywy doświadczeń i możliwości w Polsce. Na początku, w oparciu o refleksje polskich teologów, został przedstawiony związek przestrzeni publicznej z naturą teologii i zadaniami, jakie ma pełnić w Kościele i społeczeństwie. Szczególnym rysem charakterystycznym jest w tym względzie wymiar eklezjalny teologii. W dalszej kolejności zostały ukazane rodzaje przestrzeni publicznej, w których możliwa jest obecność t…
