Aluminum tri-isopropoxide as an alternative precursor for atomic layer deposition of aluminum oxide thin films
2019
Due to the safety challenges associated with the use of trimethylaluminum as a metal precursor for the deposition of alumina, different chemicals have been investigated over the years to replace it. The authors have investigated the use of aluminum tri-isopropoxide (TIPA) as an alternative alkoxide precursor for the safe and cost-effective deposition of alumina. In this work, TIPA is used as a stable Al source for atomic layer deposition (ALD) of Al2O3 when different oxidizing agents including water, oxygen plasma, water plasma, and ozone are employed. The authors have explored the deposition of Al2O3 using TIPA in ALD systems operating in vacuum and atmospheric pressure conditions. For the…
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…
Tiesību uz vārda brīvību mijiedarbība ar pašvaldību tiesībām izdot pašvaldību plašsaziņas līdzekli
2018
Mūsdienās pašvaldību plašsaziņas līdzekļi satur ne tikai ar pašvaldības domes darbu saistītu informāciju, bet arī komerciālas reklāmas un sludinājumus, kas ir galvenais ienākumu gūšanas avots privāto plašsaziņas līdzekļu īpašniekiem. Šī iemesla dēļ sabiedrībā pastāv diskusijas par to, vai pašvaldību plašsaziņas līdzekļu izdošana nepārkāpj tiesības uz vārda brīvību, neapdraud privāto plašsaziņas līdzekļu pastāvēšanu mediju tirgū un nav pretrunā godīgai konkurencei. Par pašvaldību plašsaziņas līdzekļu lomu un saturu publiskajā telpā ir pausti dažādi viedokļi. Lai gan ir saprotams privāto plašsaziņas līdzekļu īpašnieku viedoklis par to, ka pašvaldību plašsaziņas līdzekļu izdevējiem nebūtu jāie…

Risk narrations and perceptions in the COVID-19 time. A discourse analysis through the Italian press
2020
This paper explores how the risk related to the pandemic of COVID-19 was managed, narrated and perceived in Italy during the lockdown phase, from February until June 2020. To reach this aim, the study provides a discourse analysis of three main level: the official institutional discourses declaimed by the government and the health authority; the risk narration spread through the diaphragm of the Italian press, and specifically through two of the most-read newspapers in Italy (Repubblica and Corriere della Sera) and their related weeklies (Venerdì di Repubblica and Sette); finally, the diverse reactions and perceptions to the risk coming from the most affected and most vulnerable subjects, c…
Agenda and media pluralism in Al Rojo Vivo and Las Mañanas de Cuatro
2019
En: Doxa Comunicación: revista interdisciplinar de estudios de comunicación y ciencias sociales. e-ISSN 2386-3978 n. 29, 2019, pp 113-137. Aun con el auge del entorno digital e híbrido, la televisión continúa siendo el principal medio de información en España. Se toma una muestra de 50 programas (25 de “Al Rojo Vivo” y 25 de “Las Mañanas de Cuatro”) para registrar quién participa en ellos, en qué condiciones lo hacen y sobre qué temas se discute. Se aprecia un alto grado de equivalencia en la agenda establecida y una bajísima inclusión de mujeres. El Procés catalán monopolizó la atención. La metodología incluye la cuantificación de los contraargumentos recibidos por los contertulios, mostra…
Regulatory networks underlying mycorrhizal development delineated by genome-wide expression profiling and functional analysis of the transcription fa…
2017
Background: Ectomycorrhizal (ECM) fungi develop a mutualistic symbiotic interaction with the roots of their host plants. During this process, they undergo a series of developmental transitions from the running hyphae in the rhizosphere to the coenocytic hyphae forming finger-like structures within the root apoplastic space. These transitions, which involve profound, symbiosis-associated metabolic changes, also entail a substantial transcriptome reprogramming with coordinated waves of differentially expressed genes. To date, little is known about the key transcriptional regulators driving these changes, and the aim of the present study was to delineate and functionally characterize the trans…

The effect of inbreeding rate on fitness, inbreeding depression and heterosis over a range of inbreeding coefficients
2014
Understanding the effects of inbreeding and genetic drift within populations and hybridization between genetically differentiated populations is important for many basic and applied questions in ecology and evolutionary biology. The magnitudes and even the directions of these effects can be influenced by various factors, especially by the current and historical population size (i.e. inbreeding rate). Using Drosophila littoralis as a model species, we studied the effect of inbreeding rate over a range of inbreeding levels on (i) mean fitness of a population (relative to that of an outbred control population), (ii) within‐population inbreeding depression (reduction in fitness of offspring fro…
