Recognizing new trends in brain drain studies in the framework of global sustainability (2021)
(MDPI AG, 2021-03-02)
Scholars had been documenting the Brain Drain phenomenon producing scientific literature for more than 50 years. After three decades of slow but steady progress, literature about this concept has accelerated its progress ...
Emotional intelligence and academic engagement in adolescents: The mediating role of self-esteem (2021)
(Dove Medical Press Ltd, 2021)
Background: Academic engagement is a variable of vital importance in adolescence due to its relationship with academic adjustment and its protective role against risk behaviors. Therefore, the objective of this study was ...
Structural, morphological and magnetic properties of iron oxide thin films obtained by atomic layer deposition as a function of their thickness (2021)
(Elsevier B.V., 2021-07-15)
Hematite (α-Fe2O3) thin films with different thicknesses between 4 and 16 nm were synthesized by atomic layer deposition, employing 500 to 2000 cycles of FeCp2/O3. After a thermal reduction process, under a controlled ...
Comparison of sampling methods for benthic macroinvertebrates in forested wetlands (2021)
(Elsevier B.V., 2021-06)
Forest wetlands are biodiversity hotspots that perform functions of vital ecological importance, but they are among the world's most threatened ecosystems. Due to their high diversity of habitats and species, the study of ...
Chemical, physical, and sensory effects of the use of bentonite at different stages of the production of traditional sparkling wines (2021)
(MDPI AG, 2021-02)
The addition of bentonite to wine to eliminate unstable haze-forming proteins and as a riddling adjuvant in the remuage is not selective, and other important molecules are lost in this process. The moment of the addition ...
Water conflicts in Central Asia: Some recommendations on the non-conflictual use of wáter (2021)
(MDPI AG, 2021-03-02)
Central Asian states, where freshwater is a strategic resource, are oriented towards regional conflict rather than cooperation. First, the article analyses the role of the unequal distribution of freshwater that has been ...
An unprecedented π-electronic circuit involving an odd number of carbon atoms in a grossly warped non-planar nanographene (2021)
(Royal Society of Chemistry, 2021-03-28)
The formation of π-aromatic circuits along a grossly warped nanographene, C80H30, containing five- and seven-membered rings inserted into a six-membered mesh, reveals global π-circuits at the edge of the backbone. Based ...
Paraquat herbicide diminishes chemoreflex sensitivity, induces cardiac autonomic imbalance and impair cardiac function in rats (2021)
(NLM (Medline), 2021-04-01)
Paraquat (PQT) herbicide is widely used in agricultural practices despite being highly toxic to humans. It has been proposed that PQT exposure may promote cardiorespiratory impairment. However, the physiological mechanisms ...
Starch-based magnetic nanocomposite for targeted delivery of hydrophilic bioactives as anticancer strategy (2021)
(Elsevier Ltd, 2021-07-15)
Magnetic nanocomposites were synthesized for the targeted delivery of hydrophilic bioactives through guidance generated by a magnetic field. Superparamagnetic iron oxide nanoparticles (SPIONs) were used to generate ...
High sensitivity of invertebrate detritivores from tropical streams to different pesticides (2021)
(Academic Press, 2021-06-15)
Freshwater organisms are often sensitive to pesticides, but their sensitivity varies across different taxa and with pesticide type and action mode, as shown by multiple acute toxicity tests. Such variability hampers ...
