2021
Bakalaura darba tēma “Nelaimes gadījumi darba vietā un ar to saistītās izmaksas”. Bakalaura darbs ir izstrādāts uz 65 lpp., tas ietver 17 attēlus, 15 tabulas. Darba autors darbā izvirzīja mērķi noskaidrot, kas ir nelaimes gadījums darbā, kāpēc tādi notiek, kādas izmaksas rodas pusēm, notiekot nelaimes gadījumam darbā un kam jāpievērš pastiprināta uzmanība, lai kontrolētu situāciju. Darba izstrādes procesā, tika iegūts priekštats, par to, kas ir nelaimes gadījumi, kāpēc notiek nelaimes gadījumi darbā, to cēloņi, kādas izmaksas rodas iesaistītajām pusēm. Izpētīta vispārējā Latvijas nelaimes gadījumu un saistīto izmaksu statistika, kā arī detalizēti apskatīts viens salīdzinoši liels darba devē…
Feasibility studies for water reuse projects: an economical approach
2006
Usually the methodologies used to analyse the feasibility of water reuse projects are focused on the internal costs. The aim of this paper is to show a methodology to assess the feasibility of a water reuse project taking into account not just the internal impact, but also the external impact (environmental and social, for example) and the opportunity cost derived from the project. Internal benefit is obtained from the difference between internal income and internal costs. Internal income is obtained by multiplying the selling price of reclaimed water and the volume obtained. Internal costs are made up of the sum of investment costs, operating costs, financial costs and taxes. While some of…
Tikuma un laimes saistība Platona sokratiskajos dialogos
2017
Bakalaura darba Tikuma un laimes saistība Platona sokratiskajos dialogos mērķis ir noskaidrot, kā ir saistīti jēdzieni tikums (ἀρετή) un laime (εὐδαιμονία) Platona sokratiskajos dialogos. Lai sasniegtu šo mērķi, bakalaura darba autore aplūko zinātnieku sniegto materiālu par sokratiskajiem dialogiem un raksturo sokratisko izvaicāšanu, ieskicē Senās Grieķijas morālistu uzskatus par šo jēdzienu saistību, tos saattiecinot ar apgalvojumiem, kas par tikuma un laimes saistību izriet no dialogiem Gorgijs un Protagors. Dialogi tiek lasīti latviešu tulkojumā, atlasot tekstvietas, kas attiecas uz analizējamo jēdzienu saistību. Atlasītās tekstvietas tiek citētas oriģinālvalodā un tām tiek sniegti autor…
Recommendation of RILEM TC237-SIB on fragmentation test for recycled asphalt
2019
This recommendation describes how to characterize the reclaimed asphalt through the fragmentation test. The guidelines given hereafter are based on the results of a round robin test organized by the RILEM Technical Committee 237-SIB ‘‘Testing and characterization of sustainable innovative bituminous materials and systems’’ and provide information on the testing procedure, data analysis and indications for the preparation of a test report.
Investigating Tools for Sustainability Assessment of Road Pavements in Europe
2022
Sustainability assessment (SA) is a method to support decision making processes through the evaluation of system effectiveness, environmental integrity, economic valuation, and social implications [1]. SA can be carried out through the application of life-cycle-based techniques for quantitative assessment, or by performing a mainly qualitative approach via sustainability rating systems (SRS). In the field of civil engineering, many SRS have been proposed, all based on assigning point values to actions that are determined to contribute to the overall sustainability of the project. However, only few of these systems can be applied specifically to compare road pavement technologies and/or main…
A life cycle scenario analysis of different pavement technologies for urban roads.
2019
In the past, lowest price was the award criterion, given that structural capacity and safety were assured. In the last years, environmental, energy, and long-term impacts have been introduced (climate change, resource depletion, energy consumption, generated solid waste, discharged water, and emissions). Unfortunately, the introduction of new pavement technologies and materials (i.e., waste plastics) affects maintenance and rehabilitation processes and call for accurate and timeliness studies and criteria. Consequently, this paper presents an energy and environmental assessment of an Italian urban road and considers different material-related scenarios that fully comply with emerging techno…
Desalination. From a questioned resource to a necessary and strategic resource during drought situations for the water supply in the Segura River Bas…
2018
En España, la desalinización ha cobrado un gran impulso en las dos últimas décadas gracias a la aprobación en 2001 del Plan Hidrológico Nacional y en 2004 del Programa A.G.U.A. Ello ha sido motivado por dos factores principales: 1) Las recurrentes e intensas sequías en las últimas décadas, en especial, la de los años noventa en la que se puso de manifiesto la necesidad de la búsqueda de nuevas fuentes y la apuesta por los recursos hídricos no convencionales (desalinización y aguas regeneradas depuradas); y 2) Cambio del antiguo paradigma hidráulico basado en el incremento de la oferta mediante las transferencias de aguas. El objetivo de esta investigación es analizar el rol que ha desempeña…
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…
From Laboratory Mixes to Full Scale Test: Rutting Evaluation of Bio-recycled Asphalt Mixes
2021
The present paper describes the rutting behavior of innovative mixes incorporating 50% of Reclaimed Asphalt (RA) with bio-materials. They were assessed in the laboratory and in a full-scale accelerated experiment. The innovative mixes studied here contained bio-materials especially designed to help recycling by re-activating the aged binder from RA. Four mixes were evaluated: three of them are manufactured with bio-materials, (two bio-rejuvenators and one bio-binder) and one was a control mix, which was a high modulus asphalt mix (EME2). In this study, the rutting resistance of the four mixes was first evaluated in the laboratory with both European and US methods. The full-scale test was th…
Interpreting Life Cycle Assessment results of bio-asphalt pavements for more informed decision-making
2020
Due to emerging climate challenges, engineers are looking to replace the conventional asphalt pavements by utilizing bio-materials combined with Reclaimed Asphalt (RA). However, there is insufficient record in the literature assessing their environmental performance. This study addresses the analysis of the results obtained from a life cycle assessment exercise of asphalt pavements containing bio-materials and RA within their binder courses, developed within the BioRePavation project. The aim is to analyze the environmental benefits achieved, by means of hotspot mapping and sensitivity analysis of the most impactful factors of their lifecycles. Two alternatives are compared to a conventiona…
