From Buildings' End of Life to Aggregate Recycling under a Circular Economic Perspective: A Comparative Life Cycle Assessment Case Study

2021

The demolition of buildings, apart from being energy intensive and disruptive, inevitably produces construction and demolition waste (C&Dw). Unfortunately, even today, the majority of this waste ends up underexploited and not considered as valuable resources to be re-circulated into a closed/open loop process under the umbrella of circular economy (CE). Considering the amount of virgin aggregates needed in civil engineering applications, C&Dw can act as sustainable catalyst towards the preservation of natural resources and the shift towards a CE. This study completes current research by presenting a life cycle inventory compilation and life cycle assessment case study of two buildin…

On a step method and a propagation of discontinuity

2019

In this paper we analyze how to compute discontinuous solutions for functional differential equations, looking at an approach which allows to study simultaneously continuous and discontinuous solutions. We focus our attention on the integral representation of solutions and we justify the applicability of such an approach. In particular, we improve the step method in such a way to solve a problem of vanishing discontinuity points. Our solutions are considered as regulated functions.

Quality of Lake Ecosystems and its Role in the Spread of Invasive Species

2021

Abstract Lake ecosystems are important elements of hydrological regime, the quality of these ecosystems is affected by anthropogenic actions, and therefore, a variety of organisms, living in these habitats depend on the applied management solutions. Due to human activities freshwater ecosystems suffer from loss of biodiversity and increased eutrophication. Therefore, important aspects related to lake management include knowledge about the water quality, ecosystem response to climate change as well as increased risks of appearance and spreading of invasive species. Water quality, content of oxygen, nutrients, phytoplankton and distribution of macrophytes, including invasive species were anal…

Propaganda Oktaviāna Augusta valdīšanas laikā (27.g.pr.Kr. – 14.g. pēc Kr.)

2015

Bakalaura darba „Propaganda Oktaviāna Augusta valdīšanas laikā (27.g.pr.Kr.- 14.g.pēc Kr.)” mērķis ir izpētīt propagandas veidus un Oktaviāna Augusta lomu valdīšanas laikā. Darbā tiek pētīti sekojoši jautājumi: kādi bija Augusta propagandas veidi, kāda bija propagandas nozīme princepa varas leģitimēšanā, kas bija Romas republikas atjaunošanas ideja, kā Augusts radīja jaunu politisko sistēmu principātu, kādēļ miera politika palīdzēja Oktaviānam iegūt tautas simpātijas, kādu vietu vērtību un reliģijas atjaunošana ieņēma Augusta ideoloģijā. Pētījumā ir izmantoti desmit publicētie avoti un septiņi lietiskie avoti, tostarp tēlotājmāksla, templis, forums, monētas un mauzolejs. Atslēgas vārdi: pro…

A New Methodology to Assess Territorial Competence for Sustainable Local Development: The READI® (Resources-Actors-Dynamics) Matrix

2021

[EN] The ability of a territory to manage certain sustainable development processes increasingly depends on its capacity to apply previous diagnostic processes to its current situation. For this reason, methodologies that facilitate the detection of needs and/or potentialities of the territory are key to meeting its anticipated sustainable development goals. We present the most notable results of the research methodology carried out in the province of Valencia (Spain) that has enabled the construction of a matrix of indicators that allow these previous diagnostic processes to be put into practice at a local level, based on the participation of the territory's socioeconomic actors.

Promoting Food Waste Reduction at Primary Schools. A Case Study

2021

Food waste (FW) has recently attracted the interest of different institutions and has been the focus of many studies due to its important environmental, social and economic impact. This paper aims to analyze whether a didactic intervention, consisting of informing teachers and pupils and involving pupils in reducing FW, could bring about changes in the level of knowledge and attitude towards FW and in the amount of FW generated during the mid-morning break and lunch at schools. This study was conducted at a public Primary School in Valencia (Spain). Subtle changes in the level of knowledge and attitude towards FW were detected in teachers and pupils after the intervention. Around 30% of FW …

Contact between the components of a knee prosthesis: numerical and experimental study

2012

The aim of this work is the analysis of the contact area in a knee prosthesis using two different approaches. In particular, the interface between the femoral component and the polyethylene insert has been studied both numerically and experimentally. The interest in studying the contact area is related to the fact that the wear of the polyethylene insert, due to the high contact pressures, represents one of the major causes of failure of the total knee prosthesis. The possibility to evaluate the contact area at different loads and mutual position between femur and tibia is, therefore, of fundamental importance to study the service life of a prosthesis and to improve its performance. The fin…

Integrating Circularity in the Sustainability Assessment of Asphalt Mixtures

2020

Rising concerns about the impacts that the road engineering industry is imposing to the environment have redirected national road authorities to firmly re-consider the sustainability implications of their operations. Lately, though, sustainability has established a forceful correlation with the Circular Economy and its principles. The road engineering industry, therefore, is moving towards more circular approaches. However, this is occurring without the assessment of the potential impacts of such a transition. For this reason, in this study, a composite indicator, namely, Environmental Sustainability and Circularity indicator (ESCi), for investigating the potential effects that increased ci…
