The main leachate emissions of uncontrolled landfills

Dissertação para obtenção do Grau de Mestre em Engenharia do Ambiente, Perfil de Engenharia SanitáriaOne of the biggest current problems is the proper management of solid waste and other waste streams. All types of waste have a potential pollutant affecting soil resources and water resources, mainly in landfills that may not have adequate protection measures and do not know the waste placed in them. Through the study on laboratory scale it is possible to check which potential emissions to the level of leachates of uncontrolled landfills. The leachates can be compared. It is possible to say which ones have more heavy metals and organic fraction emissions. This study analyzed samples of leachate from two landfill waste in North-East Italy, near Verona, two old uncontrolled landfills. The leachate samples come from the simulation of biological reactors, operated in aerobic and anaerobic condition. The leachates were characterized in terms of pH, heavy metals such as Cd, Cr, Cu, Fe, Mn, Ni Pb, Zn, As and Hg and organic fraction (TOC, TKN and NO3). The heavy metal and organic fraction concentrations were found low in order of micrograms, and in the organic fraction in order of milligrams, per litre of leachates. In general, the concentrations in the anaerobic bioreactors were higher than in the aerobic bioreactors. The study showed that pH is a very important factor regarding the mobility of the metals in the leachate. The quality of the leachates in study have little potential for water pollution since they exhibit basic pH values (around 8), even if the residues are saturated, that is, the ability of field reached

Identification of N-terminal protein acetylation and arginine methylation of the voltage-gated sodium channel in end-stage heart failure human heart

The α subunit of the cardiac voltage-gated sodium channel, Naᵥ1.5, provides the rapid sodium inward current that initiates cardiomyocyte action potentials. Here, we analyzed for the first time the post-translational modifications of Naᵥ1.5 purified from end-stage heart failure human cardiac tissue. We identified R526 methylation as the major post-translational modification of any Naᵥ1.5 arginine or lysine residue. Unexpectedly, we found that the N terminus of Naᵥ1.5 was: 1) devoid of the initiation methionine, and 2) acetylated at the resulting initial alanine residue. This is the first evidence for N-terminal acetylation in any member of the voltage-gated ion channel superfamily. Our results open the door to explore Naᵥ1.5 N-terminal acetylation and arginine methylation levels as drivers or markers of end-stage heart failure

Social, open and personalised environments for communication and knowledge management between business and educational organisations

This pilot research describes an investigation on web-based work environments for business and educational organisations involved on collaborative projects for social innovations. The objective of this work is to identify key functionalities of ubiquitous environments for strategic communication, collaborative learning and knowledge management between enterprise and educational professionals. This qualitative study focuses on the Brazilian project "Nestlé Nutrir Crianças Saudáveis" (Nestlé Nurturing Project - Healthy Children) whose objective is to prevent teenagers' malnutrition and obesity through the collaboration and voluntary work of educational association professionals and Nestlé's employees. Semi-structured interviews and online questionnaires were applied to public relation professionals at Nestlé Company and project managers of educational organisations who participated in Nestlé Nutrir. Based on key findings represented to visual analytics, it was possible to identify that business and educational organization use a variety of different environments including for similar functionalities, such as the dissemination of their collaborative project, process and key achievements. This pilot study suggests, then, some recommendations on work environments applied to ubiquitous contexts through weSPOT -- working environment with social, open and personalised tools. Further studies will then focus weSPOT functionalities for effective partnerships between companies and educational institutions for effective communication-collaboration and collective inquiry projects for social innovation

Critical account of ideology in consumer culture: the commodification of a social movement

The study of ideology has long interested sociologists and consumer researchers alike. Much consumption research has approached ideology from various macro, meso, and micro levels of analysis. However, many studies fail to address the dialogical interplay among these three levels of analysis when examining how ideology manifests in, and interacts with, consumer identity projects. Many consumption-based studies examining ideology provide descriptive and normative accounts, affording practices of consumption emancipatory potential. In response, this research adopts a critical marketing perspective in order to draw out the macro and political implications of meso cultural production systems and micro consumption experiences and identity projects. Focusing on the contemporary American feminist movement, and on discourses around sex and sexuality, it explores how hegemonic (patriarchal) and counterhegemonic (feminist) ideologies are communicated in the marketplace, through the media, to understand their role in regard to consumers’ lived experiences and interactions with advertisements. Working within the consumer culture theory tradition, this thesis employed a variant of phenomenological interviewing that explored female emerging adults’ sexual narratives and their interpretations of sexualized ads. By generating data on a specific type of experience, inferences were drawn about how young women experience and relate to the contemporary feminist movement. In total, 14 American women, aged 20 to 31, were interviewed twice and also created media collages of what they considered ‘sexy’. Implementing a multi-step hermeneutic analysis, the data were analyzed through an iterative process, moving back and forth between the idiographic cases and theory. Through multiple iterations, micro, meso, and macro level inferences were made. This study suggests that young women foster diverse and temporary identifications with feminism in the pursuit of two, often overlapping, goals: ontological security and status. This results in a micro process of ‘ideological shifting’, which has depoliticizing effects, insofar as (anti-) feminist brands and identities were readily appropriated and discarded depending on specific contexts and situations. Thus, contrary to much work in the consumer culture theory tradition, which presents consumption as having transgressive and liberating effects, this study finds that while the young women had the power to dialogically interact with marketized (meso level) ideologies that constitute the marketplace, they failed to intercept the macro level processes of marketization and commodification and consequently did not challenge the hegemonic (patriarchal) ideology at large. In adopting a critical perspective, this study offers valuable insight into the relationship between ideology and consumer behavior. Ideology is shown to be disseminated via hegemonic processes of commodification and marketization. Because these processes occur at a macro level, counterhegemonic ideologies are hegemonized and subsequently depoliticized before even reaching the consumer on a micro level. By examining ideology across all three levels, this study finds that consumer agency is largely relegated to the realm of the marketplace, where consumers’ dialogical interactions and consumption practices do not challenge the macro ideologies or oppression at large, but merely alter their marketplace expressions

Key skills for co-learning and co-inquiry in two open platforms: a massive portal (EDUCARED) and a personal environment (weSPOT)

This paper presents a qualitative investigation on key skills for co-learning and co-inquiry in the digital age. The method applied was cyber-ethnography with asynchronous observation (forum and wiki) and synchronous discussions (webconference) for analysing skills developed by a co-learning community. This study focuses on participants from different countries who interacted during nine months in two open platforms: the massive educational portal EDUCARED of the “7th International Conference on Education 2012-2013" and weSPOT, an European “Working Environment with Social Personal and Open Technologies for inquiry based learning”. As a result of this study, it was observed that the EDUCARED portal led to the development of more explicit digital literacies, possibly because it was a simpler and familiar interface (forum). And in the weSPOT environment, experienced participants with digital technologies had more opportunities to develop other skills related to Critical-Creative Thinking and Scientific Reasoning

Como criar valor através da experiência: uma proposta APIVITA

Há 40 anos, o casal de farmacêuticos Niki e Nikos Koutsianas aproveitaram o melhor que a natureza e as abelhas tinham para lhes oferecer e criaram um sabonete preto com aroma a tomilho, o primeiro produto daquela que viria a ser a primeira marca grega de cosmética natural - a APIVITA. Hoje, a marca está presente em mais de 15 mercados, incluindo Portugal, onde começou a sua atuação em abril de 2018. Apesar da boa aceitação por parte da maioria dos consumidores, a marca encontra-se perante uma multiplicidade de desafios próprios do mercado e fase em que se encontra: diversidade tanto de marcas como de ofertas e fraca notoriedade. O objetivo deste projeto-empresa é colocar a APIVITA como pioneira numa estratégia de personalização de amenities em hotéis que correspondam ao seu posicionamento, de forma a que se demarque da concorrência e aumente as suas vendas.40 years ago, the pharmacist couple Niki and Nikos Koutsianas took advantage of nature’s resources and bees and created the black thyme-scented soap, the one that would become the first product of the first Greek brand of natural cosmetics - APIVITA. Today, the brand is present in more than 15 markets, including Portugal, where is has been operating since April 2018. Despite the good acceptance by most consumers, APIVITA is facing a multiplicity of market-specific challenges and stage: diversity of both brands and offerings and poor awareness. The objective of this projectcompany is to place APIVITA as a pioneer based in a strategy of personalization of amenities in hotels that match its positioning, so that it stands out from the competition and increases its sales
