Rumikiru, n. gen. (Scorpiones: Bothriuridae), a new scorpion genus from the Atacama Desert

Rumikiru, n. gen., a new bothriurid scorpion genus from the coastal Atacama Desert, Chile, is described. This is the first scorpion genus endemic to northern Chile. It is most closely related to Pachakutej Ochoa, 2004, from the inter-Andean valleys of Peru. Orobothriurus lourencoi Ojanguren-Affilastro, 2003, is transferred to the new genus and redescribed, creating Rumikiru lourencoi (Ojanguren-Affilastro, 2003), n. comb., and a second species of the genus, Rumikiru atacama, n. sp., is described.Fil: Ojanguren Affilastro, Andres Alejandro.

Ability of trees for microclimatic regulation the San Ginés de la Jara park (Cartagena)

[SPA] El presente trabajo tiene por objetivo demostrar la capacidad del arbolado de producir sombra y sus efectos sobre la generación de confort térmico a los usuarios del parque urbano de San Ginés de la Jara. El arbolado puede modificar el microclima local de manera sensible mediante la generación de sombra, pero esta capacidad depende de las características propias de cada especie (tamaño, forma y frondosidad) y de su gestión. Se realizaron mediciones sobre el arbolado y las sombras proyectadas mediante fotografía y un sistema de información geográfica (SIG) con el que se determinó el área total sombreada por el arbolado (Obra derivada de LiDAR-PNOA 2016 CC-BY 4.0 scne.es). Adicionalmente, se realizó un estudio de capacidad de generación de confort térmico mediante termografías y el cálculo de los índices térmicos PET (ºC) y PT (ºC). [ENG] The present work aims to demonstrate the ability of urban forest trees for shading and its effects on the generation of thermal comfort for users of the urban park of San Ginés de la Jara. Trees can modify the local microclimate in a significant way by generating shade, but this ability depends on the characteristics of each species (size, shape, and leafiness) and its management. To study it, different measurements were made on the trees and their projected shadows by photography and a geographic information system (GIS) which led determine the total area shaded by the trees (work derived from LiDAR-PNOA 2016 CC-BY 4.0 scne.es). Additionally, a thermal comfort generation capacity study was carried out using thermography and the calculation of the thermal indices PET (ºC) and PT (ºC).Este trabajo ha sido posible gracias al apoyo financiero y técnico de la empresa Actúa Servicios y Medioambiente S.L

Neutrophil gelatinase-associated lipocalin (NGAL) is related with the proteinuria degree and the microscopic kidney findings in leishmania-infected dogs

Early diagnosis of renal damage in Leishmania infected dogs may allow appropriate treatments and prevent some deaths. This study investigates neutrophil gelatinase-associated lipocalin (NGAL) as a biomarker of kidney disease in dogs experimentally infected with Leishmania infantum. Serum, urine, and kidney samples were collected from 30 infected beagle dogs and six uninfected control dogs. Based on proteinuria and azotemia values, dogs were initially classified. NGAL was measured in urine and serum samples. Then, the urinary NGAL to creatinine ratio (uNGAL/C) was calculated. Kidney samples were taken for histopathological studies, and the dogs were classified according to the severity of glomerular and tubulointerstitial lesions. In Leishmania-infected dogs, the uNGAL/C was significantly higher in proteinuric non-azotemic dogs compared with non-proteinuric non-azotemic dogs (p = 0.038). Serum NGAL (sNGAL) concentration did not differ between groups. Microscopic studies revealed several degrees of glomerulonephritis and slight focal lymphoplasmacytic interstitial nephritis in 89% and 55% of infected dogs, respectively. Urinary protein to creatinine ratio (UPC) and uNGAL/C were significantly higher in dogs with affected glomeruli compared to infected dogs without renal lesions (p = 0.045 and p = 0.043, respectively). The results show that uNGAL/C correlates with proteinuria and the presence of moderate glomerular lesions in non-azotemic dogs experimentally infected with L. infantum

Searching for BcB_c mesons in the ATLAS experiment at LHC

We discuss the feasibility of the observation of the signal from $B_c$ mesons in the ATLAS experiment of the LHC collider at a luminosity of ${\approx}\ 10^{33}$cm$^{-2}$s$^{-1}$. In particular we address the decay mode$B_c{\rightarrow}J/\psi \pi$followed by the leptonic decay$J/\psi{\rightarrow}\mu^+\mu^-$, which should permit an accurate measurement of the$B_c$mass. We performed a Monte Carlo study of the signal and background concluding that a precision of$40$MeV for the$B_c$ mass could be achieved after one year of running.Comment: Latex,7 pages including 3 uuencoded Postscript figures appended at the end of the latex fil

Development of a vertical pot for urban gardening

[SPA] El cambio climático es una realidad a la que hacer frente de manera urgente mediante el aumento de las infraestructuras verdes. Sin embargo, no en todos los espacios urbanos es posible implantar vegetación de modo convencional, lo que conlleva el uso de maceteros y contenedores. Uno de los inconvenientes que presentan los maceteros utilizados es la escasa capacidad para incorporar vegetación de grandes dimensiones y por otro lado la falta de automatización. Este trabajo aborda una fase preliminar en el desarrollo de una estructura verde urbana (contenedor inteligente o Smart Garden) autosuficiente que mejore la gestión hídrica y la apuesta por este tipo de sistemas en espacios urbanos y comerciales. [ENG] Climate change is a reality to be addressed urgently by increasing green infrastructure. However, it is not possible to implant vegetation in a conventional way in all urban spaces, which involves the use of pots and containers. One of the drawbacks of the pots used is the limited capacity to incorporate large vegetation and on the other hand the lack of automation. This work aims at a develop preliminary phase of a self-sufficient urban green structure (smart container or Smart Garden) that improves water management and the commitment to this type of systems in urban and commercial spaces.Este trabajo ha sido posible gracias al apoyo financiero y técnico de la empresa Actúa Servicios y Medioambiente S.L

Treatment of obesity in children and adolescents. How nutrition can work?

Overweight appears when persistent positive energy imbalances occur for long periods of time. Knowledge of dietary risk factors during childhood and adolescence is needed in order to design preventive measures against the increase in the prevalence of obesity and its consequences but is, however, largely missing. Longitudinal studies in children have not found clear causal associations between energy intake or diet composition and overweight development. Research has been ongoing to develop effective intervention studies for obese children but it is not clear which intervention is the most effective in assisting overweight/obese children to improve body composition without affecting growth rates. The objective of this article is to review the available knowledge on dietary risk factors for the development of childhood obesity, to discuss different dietary treatment strategies, and to propose an evidence-based approach to treat obese adolescents

Combining Mutation and Recombination to Improve a Distributed Model of Adaptive Operator Selection

We present evidence indicating that adding a crossover island greatly improves the performance of a Dynamic Island Model for Adaptive Operator Selection. Two combinatorial optimisation problems are considered: the Onemax benchmark, to prove the concept; and a real-world formulation of the course timetabling problem to test practical relevance. Crossover is added to the recently proposed dynamic island adaptive model for operator selection which considered mutation only. When comparing the models with and without a recombination, we found that having a crossover island significantly improves the performance. Our experiments also provide compelling evidence of the dynamic role of crossover during search: it is a useful operator across the whole search process. The idea of combining different type of operators in a distributed adaptive search model is worth further investigation

Comparación de la actividad física por género y grasa corporal en escolares mexicanos

Our aim was to compare the intensity of physical activity using accelerometers and heart rate monitor during physical education class and recess in students of third and fourth grade of primary education according to gender and body fat percentage. Method: To determine the intensity of physical activity accelerometers ActiGraph-GT9X and heart rate monitors Polar-bluetooth were used, in 28 boys and 26 girls during 8 physical education classes and 8 recess, to determine the percentage of body fat as normal or high bioelectrical impedance analysis was performed using the Inbody-720 equipment. The equality of variance was calculated using the Student t test for independent samples resulting a P-value less than α≤0.005 with significant differences in physical education classes between the averages of moderate to vigorous physical activity (men: 0.003; women: 0.001) and heart rate beats/min (men: 0.001; women: 0.000) in participants with normal body fat compared to high. The intensity of physical activity during recess was higher in relation to physical education classes and with a moderate to vigorous physical activity less than 50% of time class, due, is important a feedback for teachers in strategies for involving students with increased risk of obesity in moderate to vigorous physical activity.Nuestro objetivo fue comparar la intensidad de actividad física mediante acelerómetros y monitores de frecuencia cardiaca durante la clase de educación física y el recreo en estudiantes de tercero y cuarto grado de primaria de acuerdo al género y porcentaje de grasa corporal. La intensidad de la actividad física se evaluó con acelerómetros ActiGraph-GT9X y monitores de frecuencia cardiaca Polar-bluetooth en 28 niños y 26 niñas durante 8 clases de educación física y  recreo, se clasificó el porcentaje de grasa como normal o alto mediante análisis de impedancia bioeléctrica utilizando el equipo Inbody-720. La igualdad de la varianza calculada con t-Student reportó una P-Valor menor a α≤0.005 con diferencias significativas en clases de educación física entre los promedios de la actividad física moderada a vigorosa (hombres: 0,003; mujeres: 0,001) y la frecuencia cardiaca lat/min (hombres: 0,001, mujeres: 0,000) en participantes con porcentaje de grasa normal en comparación con alta. La intensidad durante el recreo fue mayor que en educación física y con actividad física moderada a vigorosa inferior al 50%, por lo anterior es importante retroalimentar constructivamente la manera de impartir la educación física mediante capacitación con estrategias didácticas para involucrar en mayor actividad física a escolares con obesidad
