Analysis of Research Topics and Scientific Collaborations in Energy Saving Using Bibliometric Techniques and Community Detection

Concern about everything related to energy is increasingly latent in the world and therefore the use of energy saving concepts has been increasing over the past several years. The interest in the subject has allowed a conceptual evolution in the scientific community regarding the understanding of the adequate use of energy. The objective of this work is to determine the contribution made by international institutions to the specialized publications in the area of energy-saving from 1939 to 2018, using Scopus Database API Interface. The methodology followed in this research was to perform a bibliometric analysis of the whole scientific production indexed in Scopus. The world’s scientific production has been analysed in the following domains: First the trend over time, types of publications and countries, second, the main subjects and keywords, third, main institutions and their main topics, and fourth, the main journals and proceedings that publish on this topic. Then, these data are presented using community detection algorithms and graph visualization software. With these techniques, it is possible to determine the main areas of research activity as well as to identify the structures of the collaboration network in the field of renewable energy. The results of the work show that the literature in this field have substantially increased during the last 10 years

Sweetened nopal flakes: a functional snack

Nopal (Opuntia spp. and Nopalea spp. genera) is a crop, recognized for its nutritional and medicinal properties; however, there are some underused species, despite the great genetic diversity in Mexico. The genus Opuntia spp. is the most consumed nopal, whereas Nopalea spp. has low commercial demand, possibly because their nutraceutical attributes are unknown. Additionally, the nopal pads or cladodes are little accepted by many consumers, due to their texture and flavor. The study objectives were 1) evaluate the nutraceutical content and antioxidant activity of four nopal cultivars: Nopalea cochenillifera cv. Texas (NT) and Opuntia ficus-indica cv. Jade (OJ), Milpa Alta (OMA), and Atlixco (OA); 2) develop nopal flakes, sweetened with rebaudioside A, from the cultivar with the best nutraceutical quality and sensory acceptability. Ascorbic acid, total phenolics, and total flavonoids were determined by spectrophotometric methods, individual flavonoids (quercetin, kaempferol, and isorhamnetin) by HPLC, and antioxidant activity by the DPPH assay. OA was the cultivar with the best nutraceutical quality. The sweetened nopal flakes of OA, at a concentration of 1.1 mg g-1 rebaudioside A, had the highest sensory acceptability by the panelists in intensity and sweetness preference. The addition of rebaudioside A improved the product’s flavor and contributed to preserve the flavonoids and antioxidant activity. These results will contribute to the chemotaxonomy of O. ficus-indica and N. cochellinifera species,and to the utilization of nopals as functional foods, due to their nutraceutical quality

Variscan metamorphism in the eastern Pyrenees and its relation to Late-Variscan magmatism revealed by U-Pb zircon dating: implications for the configuration of the Variscan Belt in the NE Iberian Peninsula

Variscan migmatites cropping out in the eastern Pyrenees were dated together with Late Variscan plutonic rocks. Upper Proterozoic–Lower Cambrian series were migmatized during a thermal episode that occurred in the interval 320–315 Ma coeval with the main Variscan deformation event (D1). The calc-alkaline Sant Llorenç–La Jonquera pluton and the gabbro–diorite Ceret stock were emplaced during a later thermal episode synchronous with the D2 deformation event. A tonalite located at the base of La Jonquera suite intruded into the upper crustal levels between 314 and 311 Ma. The gabbro–diorite stock was emplaced in the middle levels of the series in two magmatic pulses at 312 and 307 Ma. The thermal evolution recorded in the eastern Pyrenees can be correlated with that of neighbouring areas of NE Iberia (Pyrenees–Catalan Coastal Ranges) and SE France (Montagne Noire). The correlation suggests a NW–SE-trending zonation where the northeasternmost areas (Montagne Noire and eastern Pyrenees) would occupy relatively more internal zones of the orogen than the southwesternmost ones

A comparison of Clinical Risk Index for babies (CRIB-II), Score for Neonatal Acute Physiology (SNAP-II) and SNAPPE-II in predicting parenteral nutrition necessity in low birth weight preterm neonates.

Advances in perinatal care have made it possible to improve survival of low birth weight neonates. Clinical risk index for babies (CRIB-II), score for neonatal acute physiology (SNAP-II), and SNAP-perinatal extension-II (SNAPPE-II) have been used as mortality predictors for preterm infants. Feeding intolerance is very frequent in preterm neonates, and the development of an early effective biomarker for its prediction could be useful for carrying out a proper feeding strategy. Our aim was to compare the ability of CRIB-II, SNAP-II and SNAPPE-II in predict the feeding intolerance and parenteral nutrition necessity in preterm neonates. Methods: A retrospective cohort study on preterm neonates’ born at Jaen Hospital Complex with low birth weight and ≤ 36 weeks of gestation was done. Epidemiological, clinical and clinical scores CRIB II, SNAP-II and SNAPPE-II were recorded. Results: 255 low birth weight preterm neonates, 131 males (51.4%), aged ≤32 weeks of gestation (71%), were enrolled at our hospital. Parenteral nutrition needed were significantly higher in preterm neonates weighed 2500-1500 g (73.3%) and ≤ 1000g (87%). CRIB-II, SNAP-II and SNAPPE-II mean values were higher in neonates group subjected to parenteral nutrition compared with oral nutrition (p<0.05). CRIB-II and SNAPPE-II scores significantly correlated with parenteral nutrition days (p<0.05). Overall mortality rate was 11%. The 78.6% of all deceased infants needed parenteral nutrition. Conclusion: Clinical Risk Index for babies (CRIB-II) better than SNAPPE-II correlated with the feeding intolerance and thus the parenteral nutrition days in preterm neonates with low birth weight.Subvencionado: Ayuda del Plan Propio de Investigación de la UMA.

Impact of COVID-19 on University Students: An Analysis of Its Influence on Psychological and Academic Factors

The irruption of COVID-19 has had different consequences on mental health in the youth population. Specifically, the sector made up of university students has suffered an abrupt change of teaching modality because of the pandemic. As such, this paper aims to analyze the impact that COVID-19 has had on different personal factors of students: (i) satisfaction with life; (ii) lived uncertainty; (iii) depression, anxiety, and stress, as well as factors related to academic development; (iv) motivation and the creation of teaching and learning strategies during this period; and (v) the perception of the degree of adaptability to the new scenario brought about by the university system. For this purpose, a cross-sectional quantitative design was advocated through the elaboration of an SEM model, which included 1873 university students from Andalusian Universities (Spain). The results reflected the strong negative impact that the pandemic had, especially on the levels of life satisfaction and the indices of depression, anxiety, and stress of the students. Likewise, the findings reflected the relevance of the correct adaptability on the part of the university to these new circumstances. It is necessary for university institutions to focus their efforts on quality attention to students, in order to establish fluid communication with them and to adapt to their academic and personal needs.Direccion General de Investigacion y Transferencia del Conocimiento de la Junta de Andalucia (Spain)European FEDER public funds (Project I+D+i) CV20-0124

Interventions within the Scope of Occupational Therapy in the Hospital Discharge Process Post-Stroke: A Systematic Review

Stroke is one of the main causes of disability in adulthood. Its rehabilitation is a complex process that requires a multidisciplinary team of specialised professionals. The main goal of this review was to determine the impact of occupational therapy intervention post-stroke on the home discharge process. A systematic search was carried out of the following databases: Pubmed, Web of Science, PsycINFO, Scopus, Otseeker, and Dialnet. A screening was performed taking into account the type of article, including exclusively RCT, and type of intervention, only including interventions within the scope of occupational therapy that take place during the process of hospital discharge post-stroke. A total of 2285 citations were identified in the search from which 13 articles met the inclusion criteria. Comparisons of the groups indicated that early occupational therapy intervention during the process of hospital discharge can be effective in terms of functional recovery and can lead to the caregiver seeing improvements in self-efficacy and fatigue. In addition, the inclusion of a caregiver in the intervention influences the patient’s adherence to treatment, leading to a reduction in the cost of treatment and rehabilitation.This study will be supported by University of Malaga (Spain).

EZH2 regulates neuroepithelium structure and neuroblast proliferation by repressing p21

The function of EZH2 as a transcription repressor is well characterized. However, its role during vertebrate development is still poorly understood, particularly in neurogenesis. Here, we uncover the role of EZH2 in controlling the integrity of the neural tube and allowing proper progenitor proliferation. We demonstrate that knocking down the EZH2 in chick embryo neural tubes unexpectedly disrupts the neuroepithelium (NE) structure, correlating with alteration of the Rho pathway, and reduces neural progenitor proliferation. Moreover, we use transcriptional profiling and functional assays to show that EZH2-mediated repression of p21contributes to both processes. Accordingly, overexpression of cytoplasmic p21induces NE structural alterations and p21suppression rescues proliferation defects and partially compensates for the structural alterations and the Rho activity. Overall, our findings describe a new role of EZH2 in controlling the NE integrity in the neural tube to allow proper progenitor proliferation.This study was supported by grants CSD2006-00049, BFU2009-11527, BFU-2012-34261 to M.A.M.-B. and BFU2009-11527 and BIO2006-15557 to X.C. from the Spanish Ministry of Education and Science, 090210 from Fundaciò La Marató de TV3 and Fondation Jérôme Lejeune to M.A.M.-B. and 200420E578 from the CSIC to X.C.
