Biomecánica del baile flamenco. Análisis de los tiempos de pausa y actividadØ)W

En este artículo se ha estudiado los períodos de actividad y descanso en el baile flamenco. Se han grabado y analizado los bailes de 6 bailaoras profesionales que voluntariamente han participado en este estudio con una edad media de 24 ±6,06 años, un peso medio de 58,84 ±2,25 kg y una altura media de 166 ± 6,67 cm. La duración media de los bailes es de 457,67 ± 70,77 s. Se ha contabilizado como tiempo de pausa aquellos segundos durante los que no se efectuaban ningún zapateado, estos períodos tienen una duración muy corta que oscila entre 1 y 15 s. La duración media de los tiempos totales de pausa durante los bailes ha sido de 32 ± 2,10 s, lo que equivale a un 6,99% del tiempo total de baile. Por el contrario, los períodos de actividad (segundos durante los que se efectúa al menos un zapateado) son bastante más largos, de hecho un 26,29% del tiempo de baile se distribuye en períodos de una duración superior a 120 s. La duración media del tiempo total de actividad durante los bailes ha sido de 425,67 ± 41,3 s, equivalente a un 93,01% del tiempo total de baile. Los períodos de actividad superiores a 31 s suelen continuarse con períodos de pausa igual o mayores a 3 s. Pensamos que estos resultados son la base sobre la cual poder programar la preparación física específica de bailaoras de flamenco

Factores Asociados Con La Falta De Éxito En La Implementación De La Planeación Estratégica (IPE) En Empresarios Y Directivos Del Centro Empresarial De Ciudad Juárez, Chihuahua, México 2014-2015

El ejercicio de la Planeación Estratégica (PE) en las organizaciones es fundamental en la toma de decisiones para la elección de mejores alternativas y asignación óptima de recursos para alcanzar una visión de futuro. Las readecuaciones de la PE se originan entre su diseño y su implementación, por lo que es importante analizar la brecha formada entre donde culmina la planeación y cuando comienza a implementarse. La Implementación de la Planeación Estratégica (IPE) está asociada a diversos factores que generan el éxito o fracaso para el cumplimiento de la visión de las organizaciones empresariales. Los factores cambian en función del contexto en el proceso de la IPE. El desarrollo del trabajo es identificar los factores que contribuyen al éxito o fracaso de la IPE para establecer un modelo de readecuación de la Planeación Estratégica. En este trabajo se encuestaron a 85 empresarios y/o directivos participantes directos e indirectos del Centro Empresarial COPARMEX Juárez, México. En el grupo de estudio se obtuvieron hallazgos que determinan que las variables: visión compartida, liderazgo y comunicación están asociadas con la falta de éxito o fracaso de la PE. The exercise of Strategic Planning (SP) in organizations is essential for decision making in order to choose better alternatives and optimal resource display to achieve a future-focus vision. Readjustments in SP are originated between its design and its implementation, therefore is important to analyze the formed gap between where planning ends and where implementation begins. The Establishment of Strategic Planning (ESP) is associated to many factors that causes success or failure in fulfilling the vision of business organizations. Those factors change in relation of the ESP process context. The development of this study is to identify those factors that contribute to ESP’s, in order to establish an SP readjustment model. This research surveyed 85 entrepreneurs and/or directors that direct or indirectly participate with the Entrepreneurial Center COPARMEX Juarez, Mexico. In the study group, findings were obtained that show that variables: shared vision, leadership and communication are associated with the SP’s lack of success or failure

Bone turnover markers in Spanish adult men The Camargo Cohort Study

BACKGROUND. This cross-sectional study was performed to determine the reference ranges for two bone turnover markers -aminoterminal propeptide of type I collagen (P1NP) and C-terminal telopeptide of type I collagen (-CTX)- in normal adult Spanish men as measured in serum by automated methods. METHODS. A community-based population of 660 healthy men ≥ 50 years was evaluated. Fasting serum levels of P1NP, -CTX, 25-hydroxivitamin D, and intact parathyroid hormone were measured on the Elecsys 2010 automated analyzer (Roche). BMD at lumbar spine, femoral neck and total hip was determined by DXA. RESULTS. Mean age of participants was 65±9 yrs. Logarithmic transformation of both markers was performed to allow for normal distribution. Mid-95% ranges for P1NP and -CTX were 15-78 ng/ml and 0.069-0.760 ng/ml, respectively. Median and interquartile range of serum P1NP and -CTX were 33.5 [25.5;44.4] ng/ml and 0.27 [0.19;0.38] ng/ml, respectively. Mean values of P1NP (37.1±16.7 ng/ml) were similar to those previously described. -CTX mean values (0.300±0.171 ng/ml) were also similar to those quoted by the manufacturers in men younger than 70 yrs, but slightly lower than those reported in subjects older than 70 yrs. Both markers were higher among osteoporotic men. After excluding from the analysis those men who were found to have BMD below -2.5 T-score, 25OHD serum level below 30 ng/ml or serum PTH above 65 pg/ml, P1NP and -CTX ranges were 17-71 ng/ml and 0.070- 0.681 ng/ml, again respectively. CONCLUSIONS. Values obtained from this well-characterized population study provide reference ranges for serum automated P1NP and -CTX in normal Spanish adult men

Superhydrophobic supported Ag-NPs@ZnO-nanorods with photoactivity in the visible range

In this article we present a new type of 1D nanostructures consisting of supported hollow ZnO nanorods (NRs) decorated with Ag nanoparticles (NPs). The 3D reconstruction by high-angle annular dark field scanning transmission electron microscopy (HAADF-STEM) electron tomography reveals that the Ag NPs are distributed along the hollow interior of the ZnO NRs. Supported and vertically aligned Ag-NPs@ZnO-NRs grow at low temperature (135 °C) by plasma enhanced chemical vapour deposition on heterostructured substrates fabricated by sputtered deposition of silver on flat surfaces of Si wafers, quartz slides or ITO. The growth mechanisms of these structures and their wetting behavior before and after visible light irradiation are critically discussed. The as prepared surfaces are superhydrophobic with water contact angles higher than 150°. These surfaces turn into superhydrophilic with water contact angles lower than 10° after prolonged irradiation under both visible and UV light. The evolution rate of the wetting angle and its dependence on the light characteristics are related to the nanostructure and the presence of silver embedded within the ZnO NRs.

"INTERGROWTH21st vs customized fetal growth curves in the assessment of the neonatal nutritional status: a retrospective cohort study of gestational diabetes"

Background Gestational diabetes mellitus is associated with increased incidence of adverse perinatal outcomes including newborns large for gestational age, macrosomia, preeclampsia, polyhydramnios, stillbirth, and neonatal morbidity. Thus, fetal growth should be monitored by ultrasound to assess for fetal overnutrition, and thereby, its clinical consequence, macrosomia. However, it is not clear which reference curve to use to define the limits of normality. Our aim is to determine which method, INTERGROWTH21st or customized curves, better identifies the nutritional status of newborns of diabetic mothers. Methods This retrospective cohort study compared the risk of malnutrition in SGA newborns and the risk of overnutrition in LGA newborns using INTERGROWTH21st and customized birth weight references in gestational diabetes. The nutritional status of newborns was assessed using the ponderal index. Additionally, to determine the ability of both methods in the identification of neonatal malnutrition and overnutrition, we calculate sensitivity, specificity, positive predictive value, negative predictive value and likelihood ratios. Results Two hundred thirty-one pregnant women with GDM were included in the study. The rate of SGA indentified by INTERGROWTH21st was 4.7% vs 10.7% identified by the customized curves. The rate of LGA identified by INTERGROWTH21st was 25.6% vs 13.2% identified by the customized method. Newborns identified as SGA by the customized method showed a higher risk of malnutrition than those identified as SGA by INTERGROWTH21st. (RR 4.24 vs 2.5). LGA newborns according to the customized method also showed a higher risk of overnutrition than those classified as LGA according to INTERGROWTH21st. (RR 5.26 vs 3.57). In addition, the positive predictive value of the customized method was superior to that of INTERGROWTH21st in the identification of malnutrition (32% vs 27.27%), severe malnutrition (22.73% vs 20%), overnutrition (51.61% vs 32.20%) and severe overnutrition (28.57% vs 14.89%). Conclusions In pregnant women with DMG, the ability of customized fetal growth curves to identify newborns with alterations in nutritional status appears to exceed that of INTERGROWTH21s

Growth regimes of porous gold thin films deposited by magnetron sputtering at oblique incidence: from compact to columnar microstructures

Growth regimes of gold thin films deposited by magnetron sputtering at oblique angles and low temperatures are studied from both theoretical and experimental points of view. Thin films were deposited in a broad range of experimental conditions by varying the substrate tilt angle and background pressure, and were analyzed by Field Emission Scanning Electron Microscopy (FESEM) and Grazing Incidence Small-Angle X-ray Scattering (GISAXS) techniques. Results indicate that the morphological features of the films strongly depend on the experimental conditions, but can be categorized within four generic microstructures, each of them defined by different bulk geometrical patterns and pore percolation depth and connectivity. With the help of a growth model, a microstructure phase diagram has been constructed where the main features of the films are depicted as a function of experimentally controllable quantities, finding a good agreement with the experimental results in all the studied cases.Junta de Andalucía P09-CTS- 5189, TEP5283, P10-FQM-6900Comunidad de Madríd S2009/MAT–1726Ministerio de Economía y Competitividad MAT2011-29194-C02-01, CSD2008-00023, MAT2008-06652, MAT2010-21228, MAT2010-1844

Strategies for the synthesis of canonical, non-canonical and analogues of strigolactones, and evaluation of their parasitic weed germination activity

Strigolactones (SLs) are natural products with promising applications as agrochemicals to prevent infestation with parasitic weeds due to their ability to trigger seed germination. However, their use is still limited because of the low yields in which they are isolated from natural sources. As such, numerous studies have led to strategies for obtaining them, and various structural analogues, by organic synthesis. These analogues have focused attention on the study of SLs, as some of them are easier to synthesize and possess enhanced properties, such as the level of bioactivity. This review provides an overview of the synthesis of SLs, subsequently focusing on the production of analogues with the canonical structure. The germinating activity of the compounds is also described herein, with positive effects on different species of the problematic genera Striga, Orobanche and Phelipanche having been found. The highly active analogue GR24 is currently the most widely studied in the literature, and relevant structural-activity relationships have been proposed as a result of the study of derivatives functionalized in different positions. Analogues based on other natural SLs such as strigol and orobanchol have also been developed, as have some novel canonical SLs derived from eudesmanolide or guaianolide sesquiterpene lactones. This review aims to provide useful information for the development of bioactive compounds applicable in new generation herbicides, in an attempt to employ similar compounds to those produced naturally in ecosystems that provoke effective herbicide effects at low concentrations.This work was supported by the ``Ministerio de Economi ' a, Industria y Competitividad'' (MINEICO), Spain, Project AGL2017-88-083-R
