    Early daily actinometric and cloud cover data from C aceres (SW of Spain) were recovered for the period 1913–1920. The task of retrieving and digitising early actinometric data series turn out highly required due to the lack of solar radiation data throughout the first half of twentieth century. Firstly, the Arago actinometer and the procedure employed to record the actinometric data were described in detail. Additionally, in spite of being a short series, trends from recovered actinometric data were analysed. A negative trend of (0.16 ± 0.03) C/year was obtained for all-sky conditions, reaching a marked value of (0.26 ± 0.04) C/year when cloud-free days were selected in the analysis. Both trends were statistically significant at the 95% confidence level. The Katmai eruption in June 1912 likely caused anomalous low actinometric records in 1913 and 1914. These results suggest a decrease of solar radiation in C aceres during the second decade of the twentieth century which is in accordance with the final stage of the long-term negative trend in solar radiation data observed at several European sites from late nineteenth century to the beginning of the twentieth century (‘early dimming’).This work was partly funded by FEDER-Junta de Extremadura [Research Group Grant GR15137 and project IB16127] and from the Ministerio de Econom ıa y Competitividad of the Spanish Government [CGL2017- 87917-P]

    BACKGROUND: In 2017, 69 108 work-related traffic injuries with medical leave were documented, constituting 12% of all occupational injuries (OI) in Spain. AIMS: The aim of this study was to describe OI within a Spanish bank company during 2017. METHODS: A cross-sectional analysis was conducted using the company's mandatory OI records, presenting data in both absolute (n) and relative (%) frequencies. The chi-square test was employed for comparisons. RESULTS: Among the company's 10 399 employees, 176 OI cases were recorded. Most were minor musculoskeletal incidents, with one severe myocardial infarction and one mild anxiety episode. Lower limb injuries were the most prevalent. Injuries of the trunk (P < 0.001), neck (P < 0.05), and upper limbs (P < 0.001) were linked to workplace factors. Approximately 62% of OI occurred outside the workplace and resulted in more extended medical leave (P < 0.01). Traffic-related injuries accounted for 39% of OI cases and caused 49% of days lost due to OI (P < 0.001).Female gender (P < 0.001) and age over 40 years (P < 0.05) were significantly associated with OI. CONCLUSIONS: In our study, musculoskeletal injuries were the most common, with a single cardiovascular event being the most severe. OI occurring outside the workplace was more frequent and led to longer medical leaves. Notably, traffic-related injuries were especially significant, exceeding official statistics 4-fold

    A Sunspot Catalog for the Period 1952-1986 from Observations Made at the Madrid Astronomical Observatory

    Full text link
    Sunspot catalogs are very useful for studying the solar activity of the recent past. In this context, a catalog covering more than three solar cycles made by the astronomers of the Madrid Astronomical Observatory in Spain (nowadays, the National Astronomical Observatory) from 1952 until 1986 has been recovered. Moreover, a machine-readable version of this catalog has been made available. We have recovered abundant metadata and studied the reliability of this dataset by comparing it with other sunspot catalogs.Comment: 21 pages, 10 figures, accepted for publication in Solar Physic

    Long-term stability of surgical-orthodontic correction of class III malocclusions with long-face syndrome

    Objectives: In the first place, to evaluate skeletal changes of the maxilla and mandible induced by surgical-orthodontic correction of malocclusions class III with long-face syndrome and secondly, to analyze the stability of these skeletal changes in the long term (more than 6 years). Design of Study: A retrospective, unicentric and longitudinal study of 19 patients who had undergone surgical and orthodontic therapy for class III skeletal malocclusion with long-face syndrome was undertaken. A cephalometric analysis based on 8 angle measurements, and statistical analyses at three different points in time (before orthodontic treatment, after orthognathic surgery and after a retention period of at least 6 years) were carried out. Results: The changes produced following surgery show that, with the exception of the maxillary plane and the facial axis, all other variables presented changes of great statistical difference. Conclusions: Skeletal changes after orthodontic-surgical correction present maxillary advance, mandibular regression and mandibular anterorotation. The angles that represent the mandibular vertical position (ramus angle, goniac angle and mandibular plane angle) showed statistically significant relapses and no stability in contrast to the facial axis

    Ponencia presentada en: XI Congreso de la Asociación Española de Climatología celebrado en Cartagena entre el 17 y el 19 de octubre de 2018.[ES]El análisis de las tendencias de los datos actinométricos registrados en Cáceres en el periodo 1913-1920 muestra un decrecimiento significativo con pendiente (-0.16 ± 0.03) ºC/año. Además, se ha realizado el análisis de las tendencias eliminando los factores externos que pueden alterarlo (erupción del volcán Katmai en 1912) mostrando un decrecimiento significativo también, pero con pendiente mayor (-0.28 ± 0.04) °C/año. También, se han analizado las tendencias en ambos periodos (1913-1920 y 1915-1920) para las distintas estaciones del año y, además, separando las medidas actinométricas por categorías de nubes al disponer de datos de cubierta nubosa. Estos resultados sugieren un decrecimiento de la radiación solar en Cáceres durante la segunda década del siglo XX en concordancia con el descenso radiativo en superficie observado en Europa entre finales del siglo XIX y principios del XX early dimming”).[EN]The analysis of the trends of the actinometric data recorded in Cáceres in the period 1913-1920 shows a significant decrease with slope (-0.16 ± 0.03) °C/year. In addition, the analysis of the trends has been done without the external factors that can modify it (the Katmai eruption in 1912) showing a significant decrease as well, but with a greater slope of (-0.28 ± 0.04) °C/year. Also, trends have been analyzed in both periods (1913-1920 and 1915-1920) for the different seasons of the year and, in addition, separating the actinometric measurements by cloud categories because cloud cover data were recorded as well in the same period. These results suggest a decrease in solar radiation in Cáceres during the second decade of the 20th century in accordance with the radiative decrease at surface observed in Europe between the end of the 19th century and the beginning of the 20th ("early dimming").Este trabajo ha sido parcialmente financiado por FEDER-Junta de Extremadura (GR15137 y IB16127) y por el Ministerio de Economía y Competitividad del Gobierno de España (AYA2014-57556-P y CGL2017-87917-P)

    Background. Patients with inflammatory bowel disease (IBD) have a high prevalence ofemotional disturbances which worsen the symptoms of the disease. As a therapeutic alternative thatis part of a comprehensive care alongside medication, the Bonny Method of Guided Imagery andMusic (BMGIM) music-assisted therapy has achieved promising emotional improvements in patientswith chronic diseases. The objective of the study was to determine the impact of a treatment based ona BMGIM group adaptation on patients with inflammatory bowel disease (IBD) and their emotionalstate, therefore analyzing state of mind, quality of life, anxiety, depression, immunocompetence as amarker of well-being, and levels of acute and chronic stress. Methods. Longitudinal, prospective,quantitative, and experimental study including 43 patients with IBD divided into an interventiongroup (22 patients), who received eight sessions over eight weeks, and a control group (21 patients).A saliva sample was taken from each patient before and after each session in order to determinecortisol and IgA levels. Similarly, a hair sample was taken before the first and after the last session todetermine the cumulative cortisol level. All molecules were quantified using the ELISA immunoassaytechnique. In addition, patients completed several emotional state questionnaires: HADS, MOOD,and CCVEII. Results. An improvement was observed in the following states of mind: sadness, fear,anger, and depression. No significant effect was observed in state of mind in terms of happinessor anxiety, in the levels of cortisol in hair, and in patients’ perceived quality of life. A reduction incortisol was observed in saliva, although this did not significantly affect the IgA titer. Conclusions.BMGIM seems to improve the emotional state of patients with IBD.Medicin
