Vigencia de Hildegarda de Bingen: ideosemántica del "Scivias".

This research paper presents the visions of Hildegard of Bingen which are revealed in her book Scivias. According to ideosemantic theory, it discusses their important scientific contribution as well as their musical and poetic innovation. Their theological and philosophical contributions show that women played an important role in European medieval culture. The originality of Hildegard’s work commands a great deal of interest among contemporary scientists, filmmakers, and artists.Este trabajo de investigación presenta las visiones de Hidelgarde de Bingen que son reveladas en su libro Scivias. En funcion de la teoría ideosemántica se analiza la importante contribución científica así como su innovación musical y poética.

La originalidad de su obra suscita un gran interés en científicos, cineastas y artistas contemporáneos

El viaje iniciático: Brendan y Dante

The aim of this paper is to develop, by means of a comparative study, the theme of the journey as a revelation of the sense of existence, as well as its correlation with historical reality. The texts referred to are Navigatio Sancti Brendani and Divina Comedia. The existing relationships between these two texts are analysed, both considering lhe space-time structure and the three stages on which a glohal Universal vision is based.El artículo propone desarrollar mediante un estudio comparativo el tema del viaje como vía de revelación de la existencia así como su correlación con la realidad histórica. Los textos a los que se refiere son la Navigatio Sancti Brendani y la Divina Comedia. Serán analizadas las correspondencias entre los dos textos tanto en las estructuras espacio-temporales como en las tres etapas que fundamentan una cosmovisión

Abrupt fragmentation thresholds of eight zonal forest types in mainland Spain

This study quantifies patchiness of eight types of zonal forests in three biogeographic regions of mainland Spain (Atlantic, Alpine and Mediterranean) which together occupy 1,726,578 ha. Their dominant species and European Habitat Type codes (EU Directive 92/43 EEC) are: Fagus sylvatica (9120, 9130 and 9150), Quercus robur and Q. pyrenaica (9230), Q. suber (9330), Pinus uncinata (9430), P. nigra ssp. salzmannii (9530) and P. pinea (subset of 9540). We applied the Korcak’s exponent B, which describes a hyperbolic relationship between the cumulative frequency of the number of patches and their sizes. The objectives were: 1) detect possible patch size intervals in which B varies significantly, explicitly identifying area thresholds, and 2) contribute to development of a robust forest mass fragmentation indicator. Exponent B was found by segmented regression analysis. The vector data were extracted from a filtered version of the Spanish Forest Map 1:50,000 (1997–2006). After validating the procedure by applying it to a previously published dataset, we found that in all cases the patch size range could be split into two significant intervals around relatively small threshold areas of 27–101 ha. In the one on the left, the rate at which relatively large patches become less abundant was always very slow (B = 0.017–0.094). After this threshold had been passed, the rate increased abruptly (B = 1.100–2.590). Both this high fragmentation and its lack of parsimony were unexpected in zonal forest types. General interpretations converge to the coexistence of forest patches of different ages due to human pressure events.This work was supported by Tragsatec (Grupo Tragsa) [contract numbers 39.916 and 38.454]; and the Spanish National R&D&I Plan (including ERDF funds) [grant number CGL2016-78075-P]

A dataset with complete geographic distributions of eight zonal monospecific forest types in mainland Spain

Distribution area and surface are both parameters of paramount importance for habitat management, monitoring and conservation. Here we present the distribution of eight zonal forest types of mainland Spain that are consistent with the Habitat Types (HT) listed in Annex I of the European Union Habitats Directive 92/43 EC. Their dominant species and HT codes are Fagus sylvatica (9120, 9130 and 9150), Quercus robur and Q. pyrenaica (9230), Q. suber (9330), Pinus uncinata (9430), P. nigra ssp. salzmannii (9530) and P. pinea (subset of 9540). These distributions are based on tesserae from the 1:50,000 Spanish Forest Map and are the result of sorting assisted by supplementary databases. The distributions are presented as vector coverages, and provide three information levels of increasing detail: geographic distribution, basic forest type and structural forest patch. Two R scripts are also included with the dataset. They implement a segmented regression approach to investigate forest fragmentation on these or other patch-like data.Tragsatec (Grupo Tragsa) funded this research through the following projects: Climatic Regionalization and Ecosystem Fragmentation (Contract No. 39.916) and Methods to Estimate Rates of Change of Occupied Surface of Forest and Shrubland Habitat Types within their Respective Distribution Ranges (Contract No. 38.454)

Quantitative Ultrasound Changes in Echotexture and Functional Parameters after a Multicomponent Training Program in Pre-Frailty Individuals: A Pilot Randomized Clinical Trial

Objective: Currently, ultrasound imaging (USI) is considered a feasible tool in the evaluation of structural and textural muscle differences due to aging. The main aim of this study was to evaluate sonographic changes in muscular structure and function after a 12-week multicomponent training program in pre-frailty individuals. Design: A prospective, randomized, clinical trial was carried out. Participants: Thirty-two pre-frailty subjects were recruited and randomly divided into a multicomponent training program group (n = 16; Multicomponent group) and a conventional care group (n = 14; Control group) with a 12-week follow up. Main outcome measures: Rectus femoris thickness, cross-sectional area (CSA), echointensity, echovariation and vastus lateralis pennation angle tests were carried out to assess the structure and echotexture, and the force–velocity (F-V) profile for muscle power and muscle strength was employed to assess the functional parameters. Results: Statistically significant differences (p < 0.05) were shown for the left rectus femoris echointensity and in the functional parameter of muscle power after a 12-week program for the multicomponent training group compared to the conventional care group. Conclusions: Pre-frailty elderly subjects showed a decrease in rectus femoris echointensity (RF-EI) and an increase in the functional parameter of muscle power after a 12-week multicomponent training program compared to the control group

Interaction Between Caffeine and Creatine When Used as Concurrent Ergogenic Supplements: A Systematic Review

There is some controversy regarding the interactions between creatine (CRE) and caffeine (CAF) supplements. The aim of this systematic review was to study whether such ergogenic interaction occurs and to analyze the protocol to optimize their synchronous use. The PubMed, Web of Science, MEDLINE, CINAHL, and SPORTDiscus databases were searched until November 2021 following the PRISMA guidelines. Ten studies were included. Three studies observed that CRE loading before an acute dose of CAF before exercise did not interfere in the beneficial effect of CAF, whereas one study reported that only an acute supplementation (SUP) of CAF was beneficial but not the acute SUP of both. When chronic SUP with CRE + CAF was used, two studies reported that CAF interfered in the beneficial effect of CRE, whereas three studies did not report interaction between concurrent SUP, and one study reported synergy. Possible mechanisms of interaction are opposite effects on relaxation time and gastrointestinal distress derived from concurrent SUP. CRE loading does not seem to interfere in the acute effect of CAF. However, chronic SUP of CAF during CRE loading could interfere in the beneficial effect of CRE.Sin financiación4.599 JCR (2020) Q1, 15/88 Sport Sciences1.154 SJR (2020) Q1, 432/2446 Medicine (miscellaneous)No data IDR 2020UE
