Over the last decades, the interest in the development of renewable energy (RE) has grown exponentially. In the case of the European Union (EU), the Renewable Energy Directive sets rules to achieve a 32% of total energy consumption to be covered through RE by 2030. In order to achieve this goal, it is important to know what are the main driving factors of RE consumption (REC). This study aims to analyze the impact of economic and social factors on the share of REC in total energy consumption in the EU over the period 2001–2015. For doing so, we estimate a Panel Corrected Standard Error (PCSE) model. The results obtained show that economic factors have a negative effect on REC. In contrast, social factors like education exert a positive effect. This suggests that it is necessary to adopt a holistic approach that includes not only economic but also social aspects in order to foster REC.Ministry of Economy, Industry, and Competitiveness and State Research Agency of SpainEuropean Commission CS02017-86975-RUniversidad de Granada/CBU

Quantum dots based on spin properties of semiconductor heterostructures

The possibility of a novel type of semiconductor quantum dots obtained by spatially modulating the spin-orbit coupling intensity in III-V heterostructures is discussed. Using the effective mass model we predict confined one-electron states having peculiar spin properties. Furthermore, from mean field calculations (local-spin-density and Hartree-Fock) we find that even two electrons could form a bound state in these dots.Comment: 9 pages, 3 figures.

Oleoylethanolamide restores alcohol-induced inhibition of neuronal proliferation and microglial activity in striatum

Previous findings demonstrate a homeostatic role for oleoylethanolamide (OEA) signaling in the ethanol-related neuroinflammation and behavior. However, extensive research is still required in order to unveil the effects of OEA on a number of neurobiological functions such as adult neurogenesis, cell survival and resident neuroimmunity that become notably altered by alcohol. Daily consumption of ethanol (10%) for 2 weeks (6.3& #x202F;± 1.1 g/kg/day during last 5 days) caused hypolocomotor activity in rats. This effect appears to rely on central signaling mechanisms given that alcohol increased the OEA levels, the gene expression of OEA-synthesizing enzyme Nape-pld and the number of PPARα-immunoreactive neurons in the striatum. Ethanol-related neurobiological alterations such as a reduction in the number of microglial cells expressing iNOS (a cytokine-inducible immune defense) and in adult neural stem/progenitor cell (NSPC) proliferation (phospho-H3 and BrdU) and maturation (BrdU/β3-tubulin), as well as an increase in damage cell activity (FosB) and apoptosis (cleaved caspase 3) were also observed in the rat striatum. Pharmacological administration of OEA (10 mg/kg) for 5 days during ethanol exposure exacerbated ethanol-induced hypolocomotion and cell apoptosis in the striatum. Interestingly, OEA abrogated the impaired effects of ethanol on PPARα-positive cell population and NSPC proliferation and maturation. OEA also decreased astrocyte-related vimentin immunoreactivity and increased microglial cell population (Iba-1, iNOS) in the striatum. These results suggest that OEA-PPARα signaling modulates glial activation, cell apoptosis and NSPC proliferation and maturation in response to striatal-specific neurobiological alterations induced by prolonged ethanol intake in rats.This work was supported by RETICS Red de Trastornos Adictivos, Instituto de Salud Carlos III (ISCIII), Ministerio de Economía y Competitividad and European Regional Development Funds-European Union (ERDF-EU) (RD16/0017/0001); ISCIII, MINECO, ERDF-EU (JS: PI16/01374; FRF: PI16/01698; FJP: PI16/01953; AS: PI17/02026); Ministerio de Sanidad, Servicios Sociales e Igualdad and Plan Nacional sobre Drogas (JS: PNSD2015/047; AS: PND2017/043); Consejería de Economía, Innovación y Ciencia, Junta de Andalucía, ERDF-EU (FRF: CTS-8221); Consejería de Salud, Junta de Andalucía, ERDF-EU (FRF: SAS111224); German Research Foundation DFG (BL: FOR926, project CP1).

Domestic versus foreign origin of total energy use: An analysis for Brazil

We thank support from the project "Adaptation to sustainable energy transition in Europe: Environmental, socio-economic and cultural aspects (ADAPTAS)'' as part of the funding for this research. (Ministry of Economy, Industry, and Competitiveness and State Research Agency of Spain, and European Regional Development Fund, No. CSO2017-86975-R).Energy use is the major source of greenhouse gas emissions. The aim of this paper is to examine total domestic and foreign energy use across industries in Brazil over the period 1995–2015. We found that total energy use experienced an annual average growth rate close to 3%. In 2015 only three industries accounted for 37% of total energy use in Brazil: Transport, Food & Beverages, and Electricity, Gas, and Water. In these industries the share of the energy used and produced domestically was higher than the average (85.6%, 84.5% and 94.5% of the total, respectively). In contrast, other industries were increasingly reliant on foreign energy. Thus, the share of domestic use of energy produced abroad was higher than 20% in Textiles and Wearing Apparel, Electrical and Machinery, Transport Equipment and Construction. This fact extends the problem of energy-related emissions mitigation from the national to the global level.European Commission CSO2017-86975-RMinistry of Economy, Industry, and Competitiveness and State Research Agency of Spain CSO2017-86975-

Longtime Dynamics of a Semilinear Lamé System

This paper is concerned with longtime dynamics of semilinear Lamé systems ∂2 t u − μ u − (λ + μ)∇divu + α∂tu + f (u) = b, defined in bounded domains ofR3 with Dirichlet boundary condition. Firstly,we establish the existence of finite dimensional global attractors subjected to a critical forcing f (u).Writing λ + μ as a positive parameter ε, we discuss some physical aspects of the limit case ε → 0. Then, we show the upper-semicontinuity of attractors with respect to the parameter when ε → 0. To our best knowledge, the analysis of attractors for dynamics of Lamé systems has not been studied before

Dataset of the sperm proteome of stallions with different motility

This paper provides a detailed set of data on how the stal-lion sperm proteome differs among stallions with different sperm motilities, although within normal ranges. Findings distinguish proteins that may help to identify stallions of su-perior sperm motility. Sperm proteins were analyzed using a UHPLC/MS/MS system comprising of an Agilent 1290 in-finity series UHPLC coupled to an Agilent 6550 Q-TOF mass spectrometer (Agilent Technologies, Santa Clara, CA, USA). These data can be used to disclose potential targets to iden-tify good sperm samples and to study specific pathways in-volved in the regulation of sperm motility. This data article is linked to the paper "Proteins involved in mitochondrial metabolic functions and fertilization predominate in stallions with better motility Journal of Proteomics 247:104335 doi: 10.1016/j.jprot.2021.104335".(c) 2022 The Author(s).

Morbilidad Asistida y morbilidad real por infecciones respiratorias agudas

ResumenEl presente trabajo aborda el estudio de la morbilidad por Infecciones Respiratorias Agudas (IRA) en áreas del municipio Lisa en Ciudad Habana, así como en localidades del municipio Isla de la Juventud (Cuba), con objeto de caracterizar algunos aspectos de la morbilidad por demanda de consultae identificar la morbilidad real. Alrededor del 90% de las consultas por IRA fueron por primera vez y en general la razón de éstas, respecto al seguimiento fue de 5,3. A través de la búsqueda activa de enfermos se obtuvieron las tasas de morbilidad real (TMR) entre valores de 110,4 y 163,4 casos por 1000 habitantes, que fueron muy superiores a las tasas de morbilidad por demanda de consulta (TMDC) en iguales periodos de tiempo. Resultado de la división de ambas tasas se obtuvo el«índice de morbilidad real» (IMR) cuyo cociente osciló entre 5 y 15, aproximadamente. Una alta proporción (47,6%) de enfermos refirieron no haber solicitado atención médica. Estos resultados permiten hacer estimaciones aproximadas del comportamiento real de las IRA en el universo de estudio y establecer bases para un nuevo programa de control, perfeccionando ademcis la vigilancia epidemiolóigica en la atención primaria de salud.SummaryThe present work presents the study of morbidity due to acute respiratory infections (ARI) in areas of the town of Lisa in Ciudad Habana, and Isla Juventud (Cuba), to caracterise different aspects of morbidity measured by health care attendance and to measure true morbidity. About 90% of consultations for ARI were first-time consultations, while their ratio to further consultations was 5.3. True morbidity rates (TMR), obtained trough active research, ranged from 110.4 to 163.4 cases per 1000 inhabitants, considerably higher than morbidity rates measured by primary care consultations (MRPCC) in the same time period. The true morbidity index (TMI), as measured by the ratio of the two previous rates, ranged from 5 to 15. Ahigh proportion (47.6%) of cases reported no medical careattendance. These results provide approximate estimates of true morbidity in the study area, and allow the establishment of a new control program, also improving epidemiologic surveillance within primary care activities
