Diversity of freshwater Epsilonproteobacteria and dark inorganic carbon fixation in the sulphidic redoxcline of a meromictic karstic lake.

2015

Sulfidic redoxclines are a suitable niche for the growth and activity of different chemo- and photolithotrophic sulphide-oxidizing microbial groups such as the Epsilonproteobacteria and the green sulfur bacteria (GSB). We have investigated the diversity, abundance and contribution to inorganic carbon uptake of Epsilonproteobacteria in a meromictic basin of Lake Banyoles. CARD-FISH counts revealed that Epsilonproteobacteria were prevalent at the redoxcline in winter (maximum abundance of 2 × 10(6) cells mL(-1), ≈60% of total cells) but they were nearly absent in summer, when GSB bloomed. This seasonal trend was supported by 16S rRNA gene pyrotag datasets, which revealed that the epsilonprote…

From the vestiges port at the port hybrid: the experimental field of the waterfront 2.0

2012

Il contributo si propone di riflettere criticamente sulla possibilità di piani, programmi e progetti di riqualificare gli spazi portuali e di waterfront alla luce delle mutate condizioni del trasporto marittimo e passeggeri e in riferimento al conflitto tra funzioni portuali che richiedono spazi sempre maggiori e la crescita consolidata della città in cui il porto è inserito. L'armoniosa coesistenza di due realtà indipendenti, una porta attiva e una città viva, si sta tentando di raggiungere non solo attraverso l'unità fisica, ma generando flussi e sinergie. Il contributo esamina le aree di waterfront come campo di sperimentazione per un approccio sostenibile alle trasformazioni del territo…

Green Data Centres integration in smart grids: New frontiers for ancillary service provision

2017

Abstract The paper presents a study, conceived within the GEYSER FP7 co-funded European research project, on the ancillary services that Green Data Centres (GDCs) can provide, focusing, in particular, on spinning reserve. More in detail, the main contribution of the paper is to show how GDCs can be involved in the secondary frequency regulation process of a smart distribution grid, for contrasting the disturbing effects of unexpected variation of the energy production. With this aim, a real data centre, owned by Engineering S.p.A., is simulated as connected to the Medium Voltage IEEE 14-bus test grid where some RES-based generators are supposed to exist. Simulations are carried out in order…

Chapter 5.2 The Ancient Gneiss Complex of Swaziland and Environs: Record of Early Archean Crustal Evolution in Southern Africa

2007

Publisher Summary This chapter discusses the record of early Archean crustal evolution in Southern Africa. Southern Africa preserves one of the most complete and detailed records of early Precambrian crustal evolution, and the Ancient Gneiss Complex (AGC) of Swaziland and the related rocks along the southern margin of the 3.5–3.2 Ga Barberton Greenstone Belt (BGB) have played a prominent role in models for the early evolution of continental crust. The AGC is separated from the BGB by a large granitoid sheet-like pluton some 3 Ga in age and known as the Mpuluzi Batholith. In northwest Swaziland, however, small inliers of AGC gneisses occur in faulted and sheared contact with BGB rocks, and t…

Comparison of the environmental assessment of an identical office building with national methods

2019

The IEA EBC Annex 72 focuses on the assessment of the primary energy demand, greenhouse gas emissions and environmental impacts of buildings during production, construction, use (including repair and replacement) and end of life (dismantling), i.e. during the entire life cycle of buildings. In one of its activities, reference buildings (size, materialisation, operational energy demand, etc.) were defined on which the existing national assessment methods are applied using national (if available) databases and (national/regional) approaches. The ?be2226? office building in Lustenau, Austria was selected as one of the reference buildings. TU Graz established a BIM model and quantified the amou…

Rapid Detection of the ERV-K(C4) Retroviral Insertion Reveals Further Structural Polymorphism of the Complement C4 Genes in Old World Primates

2001

The fourth component of complement (C4) is coded for by two tandem-duplicated genes located in the class III region of the MHC of humans as well as a number of primates. A C4 gene size polymorphism giving rise to two gene variants of 16 and 22.3 kb length can be attributed to a complete endogenous retroviral insertion of 6.3 kb termed ERV-K(C4) in intron 9 of the long C4 genes. We developed a simple PCR-based screening assay to detect the presence of this insertion, and tested a number of unrelated animals from old world primate species. The presence of the ERV insertion in the orangutan, rhesus macaque and green monkey as well as its absence in gorillas and chimpanzees could be confirmed. …

Soil Science Challenges in a New Era: A Transdisciplinary Overview of Relevant Topics

2020

Transdisciplinary approaches that provide holistic views are essential to properly understand soil processes and the importance of soil to society and will be crucial in the future to integrate distinct disciplines into soil studies. A myriad of challenges faces soil science at the beginning of the 2020s. The main aim of this overview is to assess past achievements and current challenges regarding soil threats such as ero-sion and soil contamination related to different United Nations sustainable development goals (SDGs) including (1) sustainable food production, (2) ensure healthy lives and reduce environmental risks (SDG3), (3) ensure water availability (SDG6), and (4) enhanced soil carbo…

The European Green Deal: New Challenges for the Economic Feasibility of Energy Retrofit at District Scale

2020

The European Green Deal proposes an epochal change in the European society by transforming environmental and climatic problems into opportunities and making sustainable and fair the European Union economic system. Radical changes will also concern urban redevelopment and energy efficiency measures in order to reduce global greenhouse gas emissions. To achieve these objectives, rules and standards, as well as financial resources and assessment tools, are needed to support both urban planning and public decision process. This paper aims to analyze the existing European programs that are applied in some European smart cities, as they constitute a valuable source of information for the developm…

THE INTEGRATION OF GREEN-BUILDING TASKS AND PROJECT-DESIGN PROCESSO - CASE STUDY

2018

The development of a green-building project following a specific reference standard such as LEED, brings new conditions and restrains for all subjects involved in the process. Such changes affect technicians, owners, bureaucracy and also the management tasks either during design or construction phases.  Within this scope, the management of sustainabilityrelated activities plays a key role for the optimization of the design-project development. This research analyzes the design process of two different case-study projects undergoing the same green-building certification from the project management perspective. In both project sustainability-related activities were performed throughout the de…
