Towards sustainable production of minerals and chemicals through seawater brine treatment using Eutectic freeze crystallization and Electrodialysis w…

2022

European policy encourages the adoption of sustainable systems that promote the efficient use and recovery of minerals and chemicals. In this respect, desalination brines do contain a dramatic amount of valuable minerals and can be valorized through appropriate treatments rather than releasing them into the environment. This paper proposes an innovative brine recovery system for obtaining high purity chemicals through the integration of Eutectic Freeze Crystallization (EFC) and Electrodialysis with Bipolar Membrane (EDBM) technologies. Two separate laboratory-scale experimental campaigns were carried out to validate the potential integration of the two processes. Mirabilite (Na2SO4∙10H2O) h…

The One Savior Paradigm

2009

The one savior paradigm is discussed not only as doctrinal aspect of religious teachings but as one of mostly manifested aspect of our psychic, that should be adequately investigated. We suggest simple idea that could serve as starting cognitive model for the one savior paradigm, that might give effect in considering global aspects of humanity, e.g., such as global economy and exact sciences in more friendly connection with religious thinking.

Intervention and peace*

2018

Abstract Intervention often does not lead to peace, but rather to prolonged conflict. Indeed, we document that it is an important source of prolonged conflicts. We introduce a theoretical model of the balance of power to explain why this should be the case and to analyse how peace can be achieved: either a hot peace between hostile neighbours or the peace of the strong dominating the weak. Non-intervention generally leads to peace after defeat of the weak. Hot peace can be achieved with sufficiently strong outside intervention. The latter is thus optimal if the goal of policy is to prevent the strong from dominating the weak.

Security in Niamey : an anthropological perspective on policing and an act of terrorism in Niger

2012

ABSTRACTThe abduction of two Frenchmen in January 2011 in Niamey's supposedly most secure neighbourhood has led many to question the functioning of the city's security apparatus. This paper analyses Niamey's security landscape, initially from an historical and then from a spatial perspective. It argues that for a comprehensive analysis of security, we must first decentre our perspective on security construction, and thus take informal non-organised modes of policing just as seriously as policing by state and vigilante organisations; and second, take into account the inseparability of sociality and security, a fragile balance of trust and acceptable risk. In conclusion I argue that this focu…

Life Cycle Assessment for Supporting Eco-Design: The Case Study of Sodium–Nickel Chloride Cells

2021

The European Union is moving towards a sustainable, decarbonized, and circular economy. It has identified seven key value chains in which to intervene, with the battery and vehicle value chain being one of them. Thus, actions and strategies for the sustainability of batteries need to be developed. Since Life Cycle Assessment (LCA) is a strategic tool for evaluating environmental sustainability, this paper investigates its application to two configurations of a sodium–nickel chloride cell (planar and tubular), focusing on the active material and the anode, with the purpose of identifying the configuration characterized by the lowest environmental impacts. The results, based on a “from cradle…

Vidzemes Lielais Zviedru Kadastrs kā saimniecības vēstures avots

1942

Kadastrs - sistematizēti kādu zemes vai ūdens nogabalu vai citu objektu dati; ar nodokļiem apliekamo zemju saraksts un novērtējums pilsētās un laukos. Zemes kadastru sāka ar zemes uzmērīšanu un vērtēšanu, vienlaikus veicot muižu redukciju, atsavinot lielāko daļu muižas zemju, kuras nodeva Zviedrijas valsts pārziņā. Tas bija labi izstrādāts kadastrs, un to izmantoja no 1691. līdz 1911. gadam, t. i., 220 gadus. Tas pasaulē ir samērā mazpazīstams, un tagadējās Latvijas un Igaunijas teritorijā tam bija tikai lokāla nozīme. Muižu redukcija .17. gs. 2. pusē, pieaugot absolūtisma tendencēm Eiropā, Zviedrijas karalis Kārlis XI (Karl XI) centās nostiprināt varu visā valstī. Viens no pasākumiem bija …

Sharing-collaborative economy in tourism: A bibliometric analysis and perspectives for the post-pandemic era

2021

Sharing economy research has risen exponentially during the last 4 years. Although several theoretical revisions on this topic have been developed, a conceptual analysis based on bibliometric techniques and science mapping tools is lacking. Within this framework, this article has two aims: (i) to carry on a performance analysis to identify the outstanding themes and (ii) to visually present the scientific structure by topics of research in sharing-collaborative economy as well as its evolution to identify future directions. The resources in the Web of Science Citation Index were used. Intelligent techniques and, more specifically, the SciMAT tool (based on co-word analysis and h-index anal…

Blockchain-Based Decentralized Business Models in the Sharing Economy: A Technology Adoption Perspective

2018

Recently, blockchain technology has increasingly been deemed to enable novel “decentralized” business models for the sharing economy and thereby potentially provide an alternative to extant “centralized” sharing economy business models. Using a technology adoption perspective, our chapter explores under which circumstances such blockchain-based decentralized sharing economy business models may be widely adopted. Building on extant research, we theorize on the factors that are relevant for adoption from the individual users’ perspective. We then derive eight potential adoption scenarios of blockchain-based decentralized sharing economy business models and explore adoption using an agent-base…

Microremains from El Mirón Cave human dental calculus suggest a mixed plant/animal subsistence economy during the Magdalenian in Northern Iberia

2015

Abstract Despite more than a century of detailed investigation of the Magdalenian period in Northern Iberia, our understanding of the diets during this period is limited. Methodologies for the reconstruction of Late Glacial subsistence strategies have overwhelmingly targeted animal exploitation, thus revealing only a portion of the dietary spectrum. Retrieving food debris from calculus offers a means to provide missing information on other components of diet. We undertook analysis of human dental calculus samples from Magdalenian individuals (including the “Red Lady”) at El Miron Cave (Cantabria, Spain), as well as several control samples, to better understand the less visible dietary compo…
