Modeling transpiration and leaf temperature of urban trees – A case study evaluating the microclimate model ENVI-met against measurement data
2018
Abstract Increasing vegetation cover in cities is a key approach to mitigating urban heat excess. However, both the effect of vegetation on microclimate and the plants’ vitality need to be assessed to support and quantify the effects of such strategies. One way to assess the interactions between vegetation and the urban environment is through microclimate models that can simulate the effects of vegetation onto the urban microclimate as well as effects of urban environments onto vegetation. To provide reliable estimates microclimate models need to be parameterized based on empirically obtained data. In this paper we compare modeled transpiration rates and leaf temperatures of a leading micro…
Contrasting responses of vascular plants and bryophytes to present and past connectivity in unmanaged grasslands
2022
AbstractThe area of semi-natural grasslands has decreased dramatically causing many grassland specialist species to persist in small habitat fragments. Furthermore, ecological communities once shaped by disturbances related to traditional agriculture now face the impacts of modern agriculture and urbanization. Many of the species have become endangered due to the combined effects of habitat destruction and degradation. We studied the responses of vascular plants and bryophytes to present and past connectivity in semi-natural grasslands, while accounting for the effects of local environmental conditions. We conducted vegetation surveys in 33 fragmented, unmanaged dry grasslands in Southwest …
Designing an AnMBR-based WWTP for energy recovery from urban wastewater: The role of primary settling and anaerobic digestion
2015
The main objective of this paper is to assess different treatment schemes for designing a submerged anaerobic membrane bioreactor (AnMBR) based WWTP. The economic impact of including a primary settling (PS) stage and further anaerobic digestion (AD) of the wasted sludge has been evaluated. The following operating scenarios were considered: sulphate-rich and low-sulphate urban wastewater (UWW) treatment at 15 and 30 ºC. To this aim, the optimum combination of design/operating parameters that resulted in minimum total cost (CAPEX plus OPEX) for the different schemes and scenarios was determined. The AnMBR design was based on both simulation and experimental results from an AnMBR plant featuri…
Increasing understanding and confidence in THM simulations of engineered barrier systems
2020
Previous studies on the modelling of coupled thermo-hydro-mechanical (THM) processes in bentonite-based engineered barrier systems (EBSs) showed the sensitivity of the output quantities to changes in the input parameters. To investigate the effects of uncertainties on the modelling results, to improve the understanding of the coupled processes active in the repository near field and to gain in-depth understanding of model uncertainties of different codes, a sensitivity analysis and code comparison of EBS simulations was performed within the Task Force on Engineered Barrier Systems. The analysis included variations in material parameter values, boundary and initial conditions, considered phy…
Tehnical Aspects Regarding the Pig Classification Carcassess in Romania Between 2009–2015, by Semi-Automated Method Optigrade Pro
2019
Abstract In the paper we analyzed the evolution of the number of pig carcasses classified in Romania by the OptiGrade Pro (OGP) semiautomatic method. The analysis was conducted for the period 2009-2015. For this time, the average weight of the carcasses and their quality (thickness of the muscles and the layer of fat) were monitored.
Getting into the groove: Opportunities to enhance the ecological value of hard coastal infrastructure using fine-scale surface textures
2015
Concrete flood defences, erosion control structures, port and harbour facilities, and renewable energy infrastructure are increasingly being built in the world’s coastal regions. There is, however, strong evidence to suggest that these structures are poor surrogates for natural rocky shores, often supporting assemblages with lower species abundance and diversity. Ecological engineering opportunities to enhance structures for biodiversity conservation (and other management goals) are therefore being sought, but the majority of work so far has concentrated on structural design features at the centimetre–meter scale.\ud \ud We deployed concrete tiles with four easily-reproducible fine-scale (m…
Describing urban soils through a faceted system ensures more informed decision-making
2016
Urban areas are increasing worldwide at a dramatic rate and their soils definitely deserve more attention than they have received in the past. In urban environments, soils potentially provide the same ecosystem services as in rural and wild environments, although in some cases they are depleted of their basic functions, such as when they lose their productive and filtering capacities because of sealing, and become mere supports for infrastructures. In other cases, soils of urban areas acquire new functions that are unique to these environments. Current soil classifications fail to effectively account for the complexity of urban soils and the information that is required for their management…
The Area Of The Strait Reading Theories And Strategies For A Metropolitan Dimension
2016
Abstract Extending across a peninsular strip going from Gioia Tauro to Melito Porto Salvo on the Calabrian side, and from Milazzo to Giardini Naxos on the Sicilian side, the Strait of Sicily sees theAspromonte massif and the Peloritani mountain range as two facing stage sets of land sketching in the gulf a water piazza of a landscaping room. Described in the proposal by Giuseppe and Alberto Samona, Ludovico Quaroni, Antonio Quistelli, Sergio Musmeci, Paolo D’Orsi Villani and Leonardo Urbani, it outlines, in the county seats of Reggio Calabria and Messina, the prevalence of a Euclidean space, identifiable in the exact metrics given by the recurrence of the measuring step of the blocks drawn …
La riforma degli articoli 9 e 41 della Costituzione e la valorizzazione dell'ambiente.
2022
Con la riforma degli art. 9 e 41 della Costituzione, approvata l’8 febbraio 2022, l’ambiente entra nella Costituzione tra i principi fondamentali ed in qualità di limite all’esercizio dell’attività economica. Il saggio propone una lettura della riforma in grado di avvalorare quell’orientamento che, sin dal secolo scorso, propugnava la ricostruzione dell’ambiente come diritto fondamentale della persona, in linea con la valorizzazione dello stesso quale bene distinto dal paesaggio, in una prospettiva esistenzialista di tutela della persona. La modifica introdotta, secondo l’autore, colma un vuoto costituzionale, divenuto insostenibile alla luce degli sviluppi della tutela ambientale, così com…
Some European green roof norms and guidelines through the lens of biodiversity : do ecoregions and plant traits also matter?
2018
Abstract Green infrastructure and in particular green roofs are crucial to meet the challenge of sustainable urbanisation fostered by the current European Research and Innovation agenda. Several documents were issued in the last decades in Europe for regulating the design, construction and up-keep of roof greening. In particular, the actual German guidelines have been widely adopted as a reference basis for green roof design and regulation worldwide, because of its exhaustiveness and proven building- and landscaping tradition. With the aim to assess the effectiveness of green roof guidelines and norms in supporting plant and soil biodiversity in different ecoregions, and particularly of the…
