Phenomenology of the LHC and flavour factories
2020
Les forces i el contingut de partícules de la natura estan descrits per el Model Estàndard (ME) de física de partícules. Aquest model es va desenvolupar en la segona meitat del segle 20 gràcies al progres tant als aspectes teòrics com a la confirmació experimental de les partícules predites a experiments i col·lisionadors. El descobriment del bosó de Higgs l'any 2012 va representar una confirmació crucial del model i va iniciar una era d'exploració al Gran Col·lisionador d'Hadrons (LHC). Malgrat que l'èxit del ME va ser confirmat, alguns problemes teòrics i experimentals semblen indica que aquesta no pot ser la teoria definitiva. En aquesta tesi s'han seguit alguns dels camins que indiquen …
Flotsam samples can help explain the δ13C and δ15N values of invertebrate resting stages in lake sediment
2018
Abstract The stable isotopic composition of chitinous remains of Cladocera (water fleas) and freshwater Bryozoa (moss animals) preserved in lake sediment records can provide supporting insights into past environmental and ecosystem changes in lakes. Here we explore whether analyses of these remains isolated from lake flotsam can provide information on the driving variables affecting the isotopic composition of these remains. We collected flotsam in 53 lakes and found enough material in 33 lakes to measure the stable carbon and nitrogen isotope ratios (expressed as δ13C and δ15N values, respectively) of resting stages. These values were compared with lake characteristics, water chemistry mea…
Agri-Food Markets towards Sustainable Patterns
2020
In recent decades, the confluence of different global and domestic drivers has led to progressive and unpredictable changes in the functioning and structure of agri-food markets worldwide. Given the unsustainability of the current agri-food production, processing, distribution and consumption patterns, and the inadequate governance of the whole food system, the transition to sustainable agriculture and food systems has become crucial to effectively manage a global agri-food market able in supporting expected population growth and ensuring universal access to sufficient, safe, and nutritious food for all. Based on a critical review of the existing international literature, the paper seeks to…
Food-Based Dietary Guidelines around the World: A Comparative Analysis to Update AESAN Scientific Committee Dietary Recommendations
2021
Food-Based Dietary Guidelines (FBDG) include dietary recommendations based on food groups according to the general and accepted nutrition principles and current scientific evidence. Adoption of FBDG contributes to the prevention of malnutrition in all its forms, promotes human health, and reduces environmental impact. The present review aims to perform an international comparative analysis of the FBDG adopted in different countries from three different continents (America, Asia, and Europe), with particular reference to the Spanish Food Safety and Nutrition Agency (AESAN, Agencia Española de Seguridad Alimentaria y Nutrición) Scientific Committee dietary recommendations. A total of twelve c…
Anti-inflammatory activity in selected Antarctic benthic organisms
2014
Antarctic benthos was prospected in search for anti-inflammatory activity in polar benthic invertebrates, in two different geographical areas: deep-bottoms of the Eastern Weddell Sea and shallow-waters of the South Shetland Islands. A total of 36 benthic algae and invertebrate species were selected to perform solubility tests in order to obtain extracts that were soluble at an innocuous ethanol concentration (0.2%) for cell culture, and further test them for anti-inflammatory activity. From these, ethanol extracts of ten species from five different phyla resulted suitable to be studied in cell macrophage cultures (RAW 264.7). Cytotoxicity (MTT method) and production of inflammatory mediator…
Evolution of Trans‐ fatty acid consumption in Thailand and strategies for its reduction
2020
Eliminating industrially produced trans-fatty acids (TFAs) from the food supply is one of the World Health Organization's (WHO's) priority targets to control and prevent non-communicable diseases. This review paper describes the strategies used to reduce TFA consumption in Thailand based on a situation analysis consisting of an assessment of TFA content in the national food supply, its intake, and stakeholder-based analysis of Strengths, Weaknesses, Opportunities, and Threats (SWOT). The analysis resulted in the drafting of a regulatory approach, which was then considered by stakeholders. Bakery products containing partially hydrogenated oils (PHOs) are the major sources of TFAs in Thailand…
Race, ethnicity and ‘African-ness’ in football discourse : perspectives in the age of superdiversity
2018
Globalization, mass mobility, and economic and transcultural flows are changing the experience of diversity in many contemporary societies and communities. This is encapsulated in the notion of ‘superdiversity’, the growing complexity of what ‘diversity’ means, when new combinations of ethnicity and other variables, mobility, belonging, and identification intersect in complex, less predictable ways (see Creese & Blackledge 2010: 550–552; Blommaert & Rampton 2011). Also, the world of association football (soccer, henceforth ‘football’) is radically transformed by such processes of globalization (Giulianotti 1999; Giulianotti & Robertson 2009; Kytölä 2013). The mobility of ‘actors-in-the-fiel…
Global and local interactions in football: Comparing the development paths of Finland and Hungary
2018
The aim of this study is to increase understanding of football’s global and local contexts. More specifically, the development paths of Finnish and Hungarian football are explored and compared in four research articles from different perspectives within a global framework. These viewpoints, in addition to a historical-sociological overview in the article I, cover closely interrelated phenomena observable in the landscape of top-level football: the organization of elite youth football, the professionalization of players and the development of football stadiums. The main research question of the study is as follows: In what way have glocal interactions in men’s football shaped the development…
Les frontières de la libre circulation dans le football européen : vers une mondialisation des flux de joueurs?
2005
Les frontières étatiques sont de moins en moins pertinentes pour définir les limites entre territoires souverains. En termes de mobilité des personnes, cependant, bien que parfois déplacées à la périphérie de nouveaux territoires en gestation, elles continuent à jouer un rôle primordial dans le contrôle et la régulation des flux, surtout pour les migrants non qualifiés. Notre article se concentre sur le cas des footballeurs professionnels, une population le plus souvent considérée comme faisant partie d’une élite migratoire bien intégrée dans un marché du travail mondial, pour laquelle les frontières n’ont plus d’importance. En réalité, nous mettons en exergue l’existence de logiques géogra…
