Salt-Marsh Foraminiferal Distributions from Mainland Northern Georgia, USA: An Assessment of Their Viability for Sea-Level Studies
(Ubiquity Press, 2020-03-26)
We investigated foraminiferal distributions from two salt-marsh sites at Thunderbolt and Georgetown, in mainland northern Georgia, U.S. Atlantic coast. We analyzed modern epifaunal foraminiferal assemblages across multiple ...
Probing α‐Amino Aldehydes as Weakly Acidic Pronucleophiles: Direct Access to Quaternary α‐Amino Aldehydes by an Enantioselective Michael Addition Catalyzed by Brønsted Bases
(Wiley, 2020-10-09)
The high tendency of α-amino aldehydes to undergo 1,2-additions and their relatively low stability under basic conditions have largely prevented their use as pronucleophiles in the realm of asymmetric catalysis, particularly ...
Effect of privatisation on income inequality: A European analysis
(Springer Nature, 2020-06-15)
This study analyses the link between privatisation reforms and income inequality on a sample of 25 European countries between 2003 and 2013. Previous literature has related privatisations with the level of poverty, welfare, ...
Model validation of a packed bed LTA membrane reactor for the direct synthesis of DME from CO/CO2
(2020-10-16)
A model for simulating the direct synthesis of dimethyl ether (DME) in a packed bed membrane reactor (PBMR) has been validated, using a LTA zeolite hydrophilic membrane in a lab-scale reaction equipment. In the model, ...
Temperature based maximum power point tracking for photovoltaic modules
(Nature, 2020-07-27)
In this article authors propose a temperature based Maximum Power Point Tracking algorithm (MPPT). Authors show that there is an optimal current vs maximum power curve that depends on photovoltaic (PV) module temperature. ...
Use of Temperature Controlled Stage Confocal Raman Microscopy to Study Phase Transition of Lead Dioxide (Plattnerite)
(MDPI, 2020-05-21)
The present work concerns the study of the phase transition of plattnerite [β-PbO2 lead (IV) oxide]-based samples when they are analysed by Raman spectroscopy. The laser-induced degradation process was carried out either ...
Improving Knowledge about the Sustainable Development Goals through a Collaborative Learning Methodology and Serious Game
(MDPI, 2020-07-30)
The university is a key agent in the process of transformation towards sustainability within the framework of the 2030 Agenda. This study aims to analyze the usefulness of the collaborative learning methodology through a ...
Multilayer hazes over Saturn’s hexagon from Cassini ISS limb images
(Nature, 2020-05-08)
In June 2015, Cassini high-resolution images of Saturn's limb southwards of the planet's hexagonal wave revealed a system of at least six stacked haze layers above the upper cloud deck. Here, we characterize those haze ...
Corruption perception following privatization reforms: the moderating role of governance
(Universidad de Murcia, 2020-01-01)
Este estudio analiza la corrupción percibida tras las reformas de privatización, teniendo en cuenta el papel
del buen gobierno, en 22 países europeos entre 2002 y 2013. Un primer análisis inicial no revela cambios

Transformation in economic studies via problem-based learning: facing fears to acquire professional skills
(Taylor and Francis Group, 2020-10-20)
Over the last 40 years, the learning process in university studies has
gradually shifted from a teacher-centered approach to a studentcentered
approach. Economic and Business studies are a suitable
sector for active ...
