El impacto del cambio climático en la movilidad humana : las migraciones climáticas en el contexto internacional y europeo
2021
For decades, the migration phenomenon has been one of the thorniest regulatory issues in the European Union (EU) policy. In addition, today, the fight against climate change in all regions of the world makes the situation worse for the new ?climate refugees? or ?environmental displaced people?, whose legal status is not yet covered by the ancient 1951 Refugee Convention.
Il primo concorso per il Palazzo di Giustizia a Roma del 1884. Ricostruzione critica del progetto di Ernesto Basile
2019
1. Breve descrizione dell’oggetto di studio Il concorso del Palazzo di Giustizia di Roma si svolge in quattro fasi svolte tra il 1884 e il 1887. Il progetto per il primo concorso, del 1884, redatto dall’allora giovanissimo Ernesto Basile (Palermo 1857-1932), rivela una grande perizia progettuale che trasforma il complesso programma funzionale in un austero edificio in stile neofiorentino. I disegni originari dell’opera, non realizzata, conservati presso la Dotazione Basile del Dipartimento di Architettura dell’Università di Palermo, sono stati oggetto di studio propedeutico alle fasi di analisi, interpretazione e ricostruzione congetturale del modello digitale. 2. Stato dell’arte e riferime…
El edificio gremial de los abaixadors o tundidores, en Valencia
2020
In the ?barri del mercat?, in the city of Valencia and very close to its Lonja, there is a building complex which is the object of this study. The research, carried out from the simple field of toponymy, to the constructive analysis, lead us to suppose that it is the building of the Valencian trade union of cloth-shearers. It can be seen how the building now camouflaged by other subsequent interventions, corresponds to a type that cannot be related to those usually built in the city of Valencia. Its origins clearly from the Valencian self-governing period splendor, its dimensions and the finishes used in its construction seem to refer to a medieval workshop. A structure of great importance …

Chrząszcze w soli
2018
Kopalnia Soli „Wieliczka” jest obiektem sztucznie stworzonym przez człowieka, dawniej eksploatowanym, obecnie intensywnie odwiedzanym. Dzięki kopalni powstała nowa nisza ekologiczna, którą zaczęły zasiedlać troglofilne organizmy żywe. Jednymi z ciekawszych zwierząt żyjących w tej kopalni są chrząszcze Niptus hololeucus. Naturalnie występują w miejscach niezwiązanych z solnymi systemami podziemnymi, jednak zawleczone przystosowały się do troglobiontycznego trybu życia. Obecnie prowadzone badania ukierunkowane są m.in. na biologiczne i morfologiczne porównanie populacji troglofilnych z kopalni i żyjących poza nią. W tym celu przy pomocy pułapek Barbera pobierane są próby z 13 stanowisk z pozi…
Natriumbikarbonaatin ja beeta-alaniinin vaikutukset lyhytkestoisessa uintisuorituksessa
2012
Happo-emästasapainon säätelyllä on suuri merkitys kovatehoisessa urheilusuorituksessa. Anaerobisessa lihastyössä elimistön pH laskee ja tämä ilmenee suorituskyvyn heikkenemisenä. Uintisuorituksen energiantuotto tapahtuu suurelta osin anaerobisesti etenkin lyhyillä matkoilla (50 - 200 m), joten happo-emästasapainon säätely on merkittävässä roolissa suorituksen lopputuloksessa. Natriumbikarbonaatti on tunnetuin lisäravinne, jolla on pyritty vaikuttamaan happoemästasapainon säätelyyn urheilussa. Kiinnostus beeta-alaniinin puskurointikykyyn on lisääntynyt viime vuosina tehtyjen tutkimusten ansiosta ja sen uskotaan olevan myös hyvin tehokas puskuri. Näiden kahden aineen yhteisvaikutusta ei kuite…
Behaviour of Extractives in Norway Spruce (Picea abies) Bark during Pile Storage
2022
The current practices regarding the procurement chain of forest industry sidestreams, such as conifer bark, do not always lead to optimal conditions for preserving individual chemical compounds. This study investigates the standard way of storing bark in large piles in an open area. We mainly focus on the degradation of the most essential hydrophilic and hydrophobic extractives and carbohydrates. First, two large 450 m3 piles of bark from Norway spruce (Picea abies) were formed, one of which was covered with snow. The degradation of the bark extractives was monitored for 24 weeks. Samples were taken from the middle, side and top of the pile. Each sample was extracted at 120 °C with both n-h…
Aposematism in the burying beetle? Dual function of anal fluid in parental care and chemical defence
2017
Burying beetles (Nicrophorus vespilloides) bear distinctive and variable orange-black patterning on their elytra and produce an anal exudate from their abdomen when threatened. During breeding, the anal exudates contribute to the antimicrobial defence of the breeding resource. We investigated whether the anal exudates also provide a responsive chemical defence, which is advertised to potential avian predators by the beetle’s orange and black elytral markings. We found that that the orange-black elytral markings of the burying beetle are highly conspicuous for avian predators against range of backgrounds, by using computer simulations. Using bioassays with wood ants, we also showed that the …
Safety in Numbers: How Color Morph Frequency Affects Predation Risk in an Aposematic Moth
2021
Polymorphic warning signals in aposematic systems are enigmatic because predator learning should favor the most common form, creating positive frequency-dependent survival. However, many populations exhibit variation in warning signals. There are various selective mechanisms that can counter positive frequency-dependent selection and lead to temporal or spatial warning signal diversification. Examining these mechanisms and their effects requires first confirming whether the most common morphs are favored at both local and regional scales. Empirical examples of this are uncommon and often include potentially confounding factors, such as a lack of knowledge of predator identity and behavior. …
