Molecularly well-designed proton exchange membranes (PEMs) with a high local concentration of strongly acidic groups have the potential to fulfill the strict requirements for fuel cell operation under high temperature and low humidity. Here, we have prepared a series of well-defined and tunable PEMs based on poly(p-phenylene alkylene) backbones functionalized with sulfonated polypentafluorostyrene

This paper presents an innovative study of the port system of Rome in Imperial times through the application of an integrated approach to both archaeological analysis and material evidence. Specifically, it seeks to provide a more complete contextualization and understanding of the port system of Rome by focusing on the exploration of the physical geography of the river Tiber and its transformatio

In the last years, the matter of the Romanization of Baetica has started to receive more attention, thus reactivating a topic largely assumed to be unproblematic in earlier approaches. Stemming from this interest, the present paper reviews theoretical and methodological approaches applied so far in the study of Roman rule in Baetica, before proposing new conceptualizations, research methods and in

Antequera (Málaga) is home to one of the most important Neolithic and Copper Age megalithic landscapes in Europe, as proven by its recent declaration as a World Heritage Site by unesco on July 15th 2016. This declaration highlights the need to push ahead in the research of the Neolithic and Copper Age periods, when the megalithic phenomenon developed and the three large Antequera megaliths, Menga,

Complexity science refers to the theoretical research perspectives and the formal modelling tools designed to study complex systems. A complex system consists of separate entities interacting following a set of (often simple) rules that collectively give rise to unexpected patterns featuring vastly different properties than the entities that produced them. In recent years a number of case studies

This paper is witness to the prolific scientific production that Emilio Illarregui developed during his academic life. Sadly, this Spanish-German cooperation seeking to define more clearly the ancient city of Termes through new technologies (i.e. geophysical survey) was also his last field work. Therefore, we present the resultsof this work on the urban structures and architectural elements of thi

In the last few years, the traditional analysis of know as a factive verb has been lively debated by linguists and philosophers of language: several scholars have pointed out that know may be used non-factively in ordinary language. The aim of the present study is to expand this inquiry to other cognitive factive verbs than know, such as discover, realize, etc., and to investigate cross-linguistic

När bör det vara möjligt att genomföra markåtkomst och hur bör ett sådant system regleras rättsligt? Det är en av de frågor som avhandlingen besvarar.Markåtkomst handlar om vilka möjligheter en aktör har för att inskränka äganderätten till mark. Äganderätt generellt är viktig i samhället, den är nödvändig för att individer ska kunna handla med varandra och en fungerande marknadsekonomi. Mark har sPrivate property rights are a central and important institution in the society. These rights are a prerequisite for individuals to have incentives to invest in their properties, be able to trade with each other, economic growth and more. In some situations, private land ownership may have to be put aside for society to function adequately; since society needs to build housing, infrastructure and o

Pharmaceutical companies regularly fund patient organisations. It is important for patient organisations’ credibility that there should be transparency regarding this financial support. In Europe, the pharmaceutical industry promises to deliver transparency through self-regulation, as opposed to legally binding provisions, but self-regulation’s effectiveness is contested. We compared the industry’

Background: The aim of the study was to demonstrate the safety and effectiveness of a suture-mediated vascular closure device to perform hemostasis after an axillary artery access during endovascular procedures on the aortic valve, the aorta and its side branches. Methods: A physician-initiated, international, multicenter, retrospective registry was designed to evaluate the success rate (VARC-2 re

Chronic breathlessness occurs across many different conditions, often independently of disease severity. Yet, despite being strongly linked to adverse outcomes, the consideration of chronic breathlessness as a stand-alone therapeutic target remains limited. Here we use data-driven techniques to identify and confirm the stability of underlying features (factors) driving breathlessness across differ
