A 5500-year oxygen isotope record of high arctic environmental change from southern Spitsbergen

2017

The oxygen isotope composition of chironomid head capsules in a sediment core spanning the past 5500 years from Lake Svartvatnet in southern Spitsbergen was used to reconstruct the oxygen isotope composition of lake water (δ18Olw) and local precipitation. The δ18Olw values display shifts from the baseline variability consistent with the timing of recognized historical climatic episodes, such as the Roman Warm Period, the Dark Ages Cold Period and the ‘Little Ice Age’. The highest values of the record, ca. 3‰ above modern δ18Olw values, occur at ca. 1900–1800 cal. yr BP. Three negative excursions increasing in intensity toward the present, at 3400–3200, 1250–1100, and 350–50 cal. yr BP, are…

Decoupling Office Energy Efficiency From Employees' Well-Being and Performance: A Systematic Review

2019

Energy efficiency (i.e., the ratio of output of performance to input of energy) in office buildings can reduce energy costs and CO2 emissions, but there are barriers to widespread adoption of energy efficient solutions in offices because they are often perceived as a potential threat to perceived comfort, well-being, and performance of office users. However, the links between offices' energy efficiency and users' performance and well-being through their moderators are neither necessary nor empirically confirmed. The purpose of this study is to carry out a systematic review to identify the existing empirical evidence regarding the relationships between energy-efficient solutions in sustainab…

On thrusting, regional unconformities and exhumation of high-grade greenstones in Neoarchean orogens. The case of the Waroonga Shear Zone, Yilgarn Cr…

2017

Abstract During the Neoarchean, the dominant tectonic style progressively changed from an episodic-overturn/stagnant-lid regime to modern-style plate tectonics. The Neoarchean strengthening of continental lithosphere changed the style of deformation of orogenic belts. The case study presented here provides insights into how such transition in tectonic style occurred, a matter that is generally controversial. We present structural and metamorphic data from the c. 2660 Ma Waroonga Shear Zone (WSZ) in the Neoarchean Yilgarn orogen (Western Australia). The WSZ contains a syntectonic pluton and older, high-grade greenstones. The tectonic fabric in the pluton developed during melt-present thrusti…

RESEARCH ON STRAWBERRY PLUG PLANTS IN SOILLESS COLTIVATION

2009

n recent years, the main advances in strawberry cultivation in Italy have regarded cultivation techniques, the use of alternatives to methyl bromide and the type of propagation material used. Fresh plants have taken over from cold-stored plants in 60% of cases. This prompted the need for new studies on the cultivation of fresh strawberry plants carried out in Sicilian nurseries. This report illustrates the results of a trial carried out in Sicily to find the best plug plants grown by four nurseries located at different altitudes (Madonie mountains, Sicani mountains, Nebrodi mountans) and on the plain (Marsala) and with an open cycle soilless system. The trial was carried out at our experime…

La dimensione europea dell’ambiente e della fiscalità ambientale – L’applicazione della disciplina sul divieto di aiuti di Stato in materia ambientale

2018

Anche le agevolazioni fiscali in materia ambientale soggiaciono ai limiti derivanti dal divieto di aiuti di Stato sancito nel diritto dell'Unione europea. Ai fini della loro liceità devono, pertanto, essere previamente notificati dagli Stati membri alla Commissione europea. In relazione alla loro compatibilità col diritto europeo devono, invece, non essere selettive e non devono incidere sulle dinamiche di libera concorrenza tra gli operatori economici, sulla base dei criteri e degli standard dettati dalla Commissione europea, anche attraverso strumenti di soft law.

Review of wind tunnel modelling of flow and pollutant dispersion within and from naturally ventilated livestock buildings

2021

[EN] Ammonia emissions from naturally ventilated livestock buildings (NVLBs) pose a serious environmental problem. However, the mechanisms that control these emissions are still not fully understood. One promising method for understanding these mechanisms is physical modelling in wind tunnels. This paper reviews studies that have used this method to investigate flow or pollutant dispersion within or from NVLBs. The review indicates the importance of wind tunnels for understanding the flow and pollutant dispersion processes within and from NVLBs. However, most studies have investigated the flow, while only few studies have focused on pollutant dispersion. Furthermore, only few studies have s…

Extraction of Antioxidant Compounds and Pigments from Spirulina (Arthrospira platensis) Assisted by Pulsed Electric Fields and the Binary Mixture of …

2021

The application of pulsed electric fields (PEF) is an innovative extraction technology promoting cell membrane electroporation, thus allowing for an efficient recovery, from an energy point of view, of antioxidant compounds (chlorophylls, carotenoids, total phenolic compounds, etc.) from microalgae. Due to its selectivity and high extraction yield, the effects of PEF pre-treatment (3 kV/cm, 100 kJ/kg) combined with supplementary extraction at different times (5–180 min) and with different solvents (ethanol (EtOH)/H2O, 50:50, v/v

Horizon scanning the European bio‐based economy: a novel approach to the identification of barriers and key policy interventions from stakeholders in…

2016

There is international recognition that developing a climate-smart bioeconomy is essential to the continuation of economic development, reduction of greenhouse gas emissions, and adaptation to climatic change; Bio-based products have an important role in making this transition happen. Supporting policy interventions have been put forward at European and national levels to support innovation and development of bio-based products and services. This study asks whether suggested policy interventions reflect the needs of stakeholders and examines how these needs vary between European regions. This consultation was performed through an online survey of 447 experts actively involved in bio-based r…

Unintended Effects of Energy Efficiency Policy: Lessons Learned in the Residential Sector

2021

The European Union has set an ambitious goal to tackle climate change, and energy efficiency in the residential sector is among the measures required to close the gap between targeted and actual greenhouse gas emissions. While different policy tools have been applied, the diffusion rate of these measures remains low. A system dynamics simulation model of the residential sector was developed to assess the advantages and drawbacks of energy efficiency policy in the multi-family building sector based on experience accumulated over the last twelve years in Latvia. The model was validated in expert group model building sessions and with historical trends. Simulating the model, a hypothesis was t…
