Greenhouse gas emissions and nitrogen removal from wastewater - constructed wetland solutions
No full textSince the Paris Agreement in 2015, total carbon emissions have been controlled. However, greenhouse gas emissions from the wastewater treatment industry have increased almost every year since 2009. Although constructed wetlands have been proposed as a green water treatment technology to address climate challenges, our understanding of their role is still limited. Therefore, we review the research status of greenhouse gases in constructed wetlands and synthesize the current best estimates of their impact on the global greenhouse gas cycle from five perspectives, particularly in the field of wastewater nitrogen cycle. These perspectives include energy self-sufficiency and complete neutralization, their role as a complete ecosystem, the unique advantages compared to other treatment methods, countermeasures in special environments, and future development strategies. We believe that new insights and innovations will promote the practical application of constructed wetlands and potentially achieve complete greenhouse gas neutralization in the wastewater treatment industry
Dalla Terra del Fuoco all’Italia postunitaria: le collezioni fuegine e la costruzione di una nazione
No full textIl contributo offre una riflessione di carattere antropologico a partire dalle collezioni museali italiane di interesse etnologico provenienti dalla Terra del Fuoco, interrogandole come oggetti in grado di parlare non solo del passato, ma anche delle tensioni, rivendicazioni e possibilità del presente. L’obiettivo è osservare in che modo le storie connesse a questi oggetti riflettano, e a volte contribuiscano a costruire, la memoria storica di uno Stato nazionale in cerca di legittimazione e identità, ma anche come possano oggi essere risignificati attraverso pratiche partecipative e dialogiche con le comunità di interesse.The contribution offers an anthropological reflection starting from the Italian ethnological museum collections originating from Tierra del Fuego. These objects are examined as artefacts capable of speaking not only about the past but also about tensions, claims, and possibilities of the present. The aim is to observe how the histories connected to these objects reflect – and at times help to shape – the historical memory of a nation-state in search of legitimation and identity, as well as to explore how they might be re-signified today through participatory and dialogical practices with source communities

Lo sfruttamento della razza. Le nuove gerarchie della segregazione
No full textWhen Cedric J. Robinson deconstructed the concept of racial capitalism, he explained that the history of capitalism has been heavily based on its link to racism and the exploitation of enslaved people. Although slavery was formally abolished centuries ago, today it is possible to revive this concept to describe the way in which social and racial division of labour is applied to racialised and/or migrant people in Europe and Italy. In this context, migrants and/or racialised people find themselves in dehumanising paradoxes: on the one hand, they serve the country's economy, but at the same time they must be expelled or marginalised, in a blackmailing limbo often made up of irregularities and semi-slavery systems. We are faced with a form of institutional racism which, precisely because it is perpetrated by the state, is inherent in the laws in force, created specifically for a particular social and racial category, preventing the self-determination of immigrants and/or racialised people. This book deconstructs systemic racism, dismantles the rhetoric of “ethnic replacement”, and illustrates the production of subordination and deprivation of rights that occurs along colour lines
exoALMA. III. Line-intensity Modeling and System Property Extraction from Protoplanetary Disks
No full textThe ALMA large program exoALMA offers a unique window into the three-dimensional physical and dynamical properties of 15 circumstellar disks where planets may be actively forming. Here, we present an analysis methodology to map the gas disk structure and substructure encoded in 12CO, 13CO, and CS line emission from our targets. To model and characterize the disk structure probed by optically thin species, such as CS and, in some cases, 13CO, we introduce a composite line profile kernel that accounts for increased intensities caused by the projected overlap between the disk’s front and back side emission. Our workflow, built on the discminer modeling framework, incorporates an improved iterative two-component fitting method for inclined sources (i > 40∘) to mitigate the impact of the disk back side on the extraction of velocity maps. Also, we report best-fit parameters for the Keplerian stellar masses, as well as inclinations, position angles, systemic velocities, rotation direction, and emission surfaces of the disks in our sample
Tradurre il Tagelied Slâfest du friedel ziere? di Dietmar von Aist
No full textSlâfest du friedel ziere? is probably the first German Tagelied. It has raised problems of interpretation, as can be read ranging from the genre of the pastourelle to the hôhe Minne. After presenting the main aspects of the text, we will analyse its translations into modern German, English, French and Italian, focusing on the crucial words to determine the position taken by the translators about the content of the poem, which in many respects remains open to different interpretations
Can blockchain revolutionize meat production? Addressing transparency, trust, and compliance in conventional and cultured meat
Get PDFBackground
The demand for safe and sustainable meat production is increasing, necessitating innovative solutions for food safety, transparency, and regulatory compliance. Blockchain technology has emerged as a potential tool to address these challenges, particularly in the conventional meat sector. However, its application in the cultured meat industry remains underexplored, raising questions about its effectiveness in enhancing trust, traceability, and regulatory adherence in this emerging sector.
Scope and approach
This study conducts a scoping review following the PRISMA protocol to examine the role of blockchain in both conventional and cultured meat industries. The review was based on searches conducted in June 2024 using two major databases— Scopus and Web of Science —and focused on peer-reviewed literature related to blockchain applications in meat production. The search covered publications up to mid-2024 and targeted titles, abstracts, and keywords using terms such as "blockchain", "meat supply chain," and "cultured meat". After applying inclusion and exclusion criteria, 14 relevant empirical studies were selected for full-text analysis.
Key findings and conclusions
Findings indicate that blockchain significantly improves traceability and trust, particularly in ensuring product authenticity and safety. It facilitates regulatory compliance by enabling stakeholder collaboration and maintaining auditable data trails. Internet of Things integration further enhances monitoring capabilities. However, challenges such as data interoperability, high implementation costs, and the absence of standardized protocols hinder broader adoption. Overcoming these barriers is crucial to unlocking blockchain's full potential. Future research should focus on blockchain integration strategies, consumer perceptions, and regulatory frameworks to support its adoption in cultured meat production
The geopolitics of space exploration in Africa: South Africa and the Square Kilometre Array (SKA) project
No full textOver the past two decades, African states have rapidly expanded investments in outer space. Attracted by low-cost earth observation and access to global astronomy networks, many have founded national space agencies and mobilized resources for a new ‘space age’. At the centre stands the Square Kilometre Array (SKA), an international effort to build the world’s largest radio telescope. Drawing on long-term fieldwork in South Africa, I analyse the SKA’s geopolitics as a planetary object that condenses layered histories and relations. Hosted in the semi-arid Karoo, the infrastructure links metropolitan nodes in Cape Town and Johannesburg, connects knowledge networks across southern, eastern, and western Africa, and plugs into investments, data flows, and expertise tied to astronomy hubs in Europe, Asia and North America. Framed by a modernist vision that casts outer space as a frontier for African development, industrialisation and global repositioning, the SKA simultaneously materialises spatial legacies of segregation and infrastructural logics of extraction. As it aspires to de-link from historical marginalisation and leapfrog into a high-tech future, it also reinscribes contestations over land and resources, refracting colonial and apartheid histories of appropriation within contemporary struggles over world-making amid geopolitical turbulence
Constraining constructions with WordNet: pros and cons for the semantic annotation of fillers in the Italian Constructicon
No full textThe paper discusses the role of WordNet-based semantic classification in the formalization of constructions, and more specifically in the semantic annotation of schematic fillers, in the Italian Constructicon. We outline how the Italian Constructicon project uses Open Multilingual WordNet topics to represent semantic features and constraints of constructions
Sustainable food packaging system: Status of regulatory initiatives and issues on plastic use in Tunisia, Kenya, Uganda and Tanzania African countries
Get PDFBackground: Sustainable food packaging is not only an environmental necessity, but also a crucial part of the broader strategy to reduce food waste and promote sustainable development in Africa, as in all countries around the world.
Scope and approach: The review gives an overview of the current landscape of food packaging systems in Africa, with a specific focus on Tunisia, Kenya, Uganda and Tanzania, countries actively involved in sustainable food packaging researches under the EU Horizon2020 FoodLAND project. The analysis begins with a description of the most used packaging materials and highlights the environmental and health issues of fossil-based plastics. National policies aimed at reducing plastic use and pollution are then examined. Finally, some relevant studies on bio-based alternatives using local resources are reviewed.
Key findings and conclusions: The development of sustainable food packaging in Africa faces major challenges, but also holds a great potential. The continent is still largely reliant on traditional (e.g. plant leaves) and conventional (e.g. fossil-based plastics) materials. The former offer limited food protection, while the latter contribute to environmental pollution. Some policy/regulatory initiatives have been introduced to reduce plastic use, their effect is often limited due to several challenges. The reviewed studies demonstrate the interest of the African scientific communities on sustainable packaging solutions, however most of them remain at lab-scale and need validation. Customised approaches that consider the different socio-economic and cultural realities of African countries can help overcome current limitations of local packaging system, especially through collaboration between academia, industry and policy makers
