Publiskas lietas, kas var piederēt privātpersonai
2018
Maģistra darbā “Publiskas lietas, kas var piederēt privātpersonai” ir analizēts modificētais privātīpašums, kas konstatējams gadījumā, kad publiska lieta vai tās daļa atrodas privātpersonas īpašumā. Darbā pētīti privāto ūdeņu publiski tiesiskie lietošanas tiesību aprobežojumi, tauvas joslas lietošanas tiesību aprobežojumi un īpaši aizsargājamo dabas teritoriju lietošanas tiesību ierobežojumi. Darbā konstatēts privāto ūdeņu, kuros zvejas tiesības pieder valstij, tauvas joslas un īpaši aizsargājamo dabas teritoriju piešķīrums un publiskās lietas veids. Izpētīts modificētā privātīpašuma parastās un sevišķās lietošanas apjoms un tā ietekme uz īpašnieka lietošanas tiesību apjoma samazināšanos.
De participació local. Una proposta metodològica desde la investigació-acció-participativa
2018
Citizen participation is an increasingly prevalent term in our society. In the process of deployment in the municipal area, progressively local corporations make efforts to innovate practices and develop experiences of citizen participation in defining policies and public affairs, and allocating budgets. While innovation has been advanced with regard to the tools and mechanisms to be used to promote participation, many of the initiatives and experiences have focused more on the implementation of the vote than in the different social processes inherent in the participation. Moreover, we are faced with the absence of a methodological guide that allows approaching a project or strategic plan o…
Applying an operating model for the environmental risk assessment in Italian Sites of Community Importance (SCI) of the European Commission Habitats …
2013
The fast development of agro-biotechnologies asks for a harmonized approach in risk analysis of GMO's releases, where "risk analysis" entails the assessment, management and communication of risk. Risk assessment consists in the evaluation of the likelihood that a hazard occurs, associated with the presence of the receptor(s) in the receiving environment, and the determination of their potential degree of exposure to the hazard. The whole process has to be both science based and applied case by case, and it involves a very complicated procedure that needs to be transformed in an operational and standardized tool. Beginning in 2003, an expert group on behalf of the Italian Ministry of the Env…
Toward Sustainable PLA-Based Multilayer Complexes with Improved Barrier Properties
2019
Poly(lactic acid) or PLA is currently considered as one of the most promising substitutes of conventional plastics, with low environmental impact, especially for food packaging applications. Nevertheless, some drawbacks, such as high permeability to oxygen, are still limiting its industrial applications. The objective of this study was to highly increase the oxygen barrier performance of PLA without compromising its sustainable nature and following the principles of circular economy perspective. Coproducts coming from mill industries, such as wheat gluten proteins (WG), were used to produce PLA-WG-PLA multilayer complexes with improved barrier performance. Different technologies of industri…
Eiropas plekstes (Platichthys flesus) un Baltijas plekstes (Platichthys solemdali) sugu diferencēšana
2022
Jau gandrīz gadsimtu plekstei ir zināmas vairošanās stratēģijas atšķirības Baltijas jūra. Jaunākie pētījumi apliecinājuši, ka tie nav ekotipi, bet ir atšķirīgas sugas. Iepriekš zināma bija tikai Eiropas plekste (Platichthys flesus), kas nārsto dziļūdens nogāzēs ar pelaģiskeim ikriem. Jaunatklātā suga Baltijas plekste (Platichtys solemdali) vairojas piekrastē ar bentiskiem ikriem un tā ir vienīgā endēmā zivs suga Baltijas jūrā. Līdz šim sugas atšķirt var tikai ar ikru morfoloģiju un ģenētiskajām analīzem. Baltijas jūras ūdens sāļumam samazinoties un anoksiskajām zonām palielinoties, Eiropas plekstes populācijas var tikt apdraudētas. Nepieciešams noteikt viegli pielietojamas metodes sugu dife…

Síntesis y caracterización de poliuretanos termoplásticos basados en policarbonato dioles. Relación estructura/propiedades.
2012
Los poliuretanos son una familia de polímeros muy versátil, utilizados en un amplio rango de aplicación, desde las espumas rígidas-flexibles, materiales elastómeros, recubrimientos, adhesivos, hasta materiales con aplicaciones biomédicas. Esta gran versatilidad es debida a que los reactivos utilizados en la síntesis de los poliuretanos son muy variados, permitiendo la gran versatilidad en la formulación del poliuretano y en las propiedades del mismo. Los poliuretanos termoplásticos elastómeros son copolímeros de bloque, que a temperatura ambiente se comportan como elastómeros entrecruzados, y sin embargo a diferencia de los elastómeros convencionales, por acción del calor se pueden conforma…
Doświadczanie migracji w opisach polskich imigrantów
2017
Wykorzystane w niniejszym tekście dane są efektem badań przeprowadzonych w 2013 i 2014 r. Badania pozwoliły na ukazanie indywidualnego rozumienia sytuacji migracji przez jej uczestników. Wypowiedzi bezpośrednich aktorów społecznych, jakimi są migranci, pomogły zilustrować migrację jako socjologiczny fenomen, w którym można zaobserwować aktualnie zachodzące szersze zmiany społeczne.
Effects of Polyacrylic Acid Pre-Treatment on Bonded-Dentine Interfaces Created with a Modern Bioactive Resin-Modified Glass Ionomer Cement and Subjec…
2018
Objectives: Resin-modified glass ionomer cements (RMGIC) are considered excellent restorative materials with unique therapeutic and anti-cariogenic activity. However, concerns exist regarding the use of polyacrylic acid as a dentine conditioner as it may influence the bonding performance of RMGIC. The aim of this study was to evaluate the effect of different protocols for cycling mechanical stress on the bond durability and interfacial ultramorphology of a modern RMGIC applied to dentine pre-treated with/without polyacrylic acid conditioner (PAA). Methods: The RMGIC was applied onto human dentine specimens prepared with silicon-carbide (SiC) abrasive paper with or without the use of a PAA c…
