Is it appropriate protective figure "Plant Micro-Reserves" to protect tree species? The example of Betula pendula subsp. fontqueri in "La Garganta de los Caballeros" (Ávila)

The figure of protection "micro-reserves" was created in the Region of Valencia (ANONYMOUS, 1994) with the aim of protecting endangered plant species. This is one of the areas of greatest floristic richness and uniqueness of the western Mediterranean. In this area rare, endemic or threatened vascular flora has a peculiar distribution: they appear to form small fragments spread over the entire region (LAGUNA, 1994; LAGUNA, 2001) The protection of every these small populations of great scientific value has significant challenges. It doesn´t try to protect every species that set out in Annex IV of the by then existing Law 4 / 1989 (repealed in 2007), or to protect to the most ecological level with the creation of Natural Protected Area but an intermediate level: the plant community of small size. According to the decree: “as Micro-Reserve will be declared the natural parcels of land under 20 hectares that contain a high concentration of rare plants, endemic, threatened or of high scientific interest” (ANONYMOUS, 1994) . Of course, the statement of an area as micro-reserve carries certain prohibitions that are harmful to the vegetal communit

Circadian rhythms of proliferation events in two mouse carcinomas

We studied the index of DNA synthesis (DNAs) of two cellular carcinomas: the hepatocellular ES12a and the mammary TN60 of mice, throughout one circadian cycle. In the results, we observed that both tumors have circadian rhythms (CRs), but the peaks of DNAs vary. Besides, the mean of DNAs along 24 h shows significative differences, the TN60 has higher values than the ES12a. These observed CR in the DNAs index in both carcinomas mean that, at least in partly, the proliferation of cancer cells can be regulated by endocrine factor as it normally occurs in ordinary cells. The big problem we can find for the chronopharmacology is that it is impossible to know in advance the rate of proliferation of each tumor.Fil: Garcia, Marcela. Universidad Nacional de la Plata.

Experimental Robot Model Adjustments Based on Force-Torque Sensor Information

The computational complexity of humanoid robot balance control is reduced through the application of simplified kinematics and dynamics models. However, these simplifications lead to the introduction of errors that add to other inherent electro-mechanic inaccuracies and affect the robotic system. Linear control systems deal with these inaccuracies if they operate around a specific working point but are less precise if they do not. This work presents a model improvement based on the Linear Inverted Pendulum Model (LIPM) to be applied in a non-linear control system. The aim is to minimize the control error and reduce robot oscillations for multiple working points. The new model, named the Dynamic LIPM (DLIPM), is used to plan the robot behavior with respect to changes in the balance status denoted by the zero moment point (ZMP). Thanks to the use of information from force-torque sensors, an experimental procedure has been applied to characterize the inaccuracies and introduce them into the new model. The experiments consist of balance perturbations similar to those of push-recovery trials, in which step-shaped ZMP variations are produced. The results show that the responses of the robot with respect to balance perturbations are more precise and the mechanical oscillations are reduced without comprising robot dynamicsThe research leading to these results received funding from the RoboCity2030-III-CM project (Robótica aplicada a la mejora de la calidad de vida de los ciudadanos.

Musicality and play in early childhood: the scaffolding that forms of vitality play provide to pretend play

El juego de ficción, aquel que comporta la creación de una situación imaginaria, ha sido un objeto de estudio privilegiado en la psicología del desarrollo y se ha señalado su rol en el desarrollo de funciones psicológicas complejas. Recientemente, gracias a la utilización de herramientas de análisis de las artes temporales, se ha documentado una nueva forma de juego, el juego con las formas de la vitalidad, cuyo foco es la repetición y variación de motivos sonoro-kinéticos de modo interactivo, en detrimento de cualquier contenido figurativo. Se ha observado que durante el tercer año de vida este tipo de juego se presenta de modo combinado con el juego de ficción y que en esos casos podría ser parte del andamiaje del desarrollo del juego de ficción. El objetivo del presente estudio fue realizar un microanálisis de los sonidos y movimientos de una escena de juego de ficción combinado con juego con las formas de la vitalidad de una niña de1año y 11 meses de edad, con el fin de conocer cómo se produce dicho andamiaje. Entre los resultados se destacan la presencia de sincronía interactiva basada en un pulso subyacente, la construcción de una mutualidad entre adulto e infante a partir de la calidad de los motivos compartidos, la ampliación del espacio de juego y el sostenimiento de la atención conjunta y la fluidez interactiva.The pretend play, one that involves the creation of an imaginary situation, has been a privileged object of study in developmental psychology framed in the linguistic turn. Its important role in the development of complex psychological functions, such as language, theory of mind or narrative capacity, has been pointed out. In recent years, there has been a change in focus in the human sciences that has been dubbed the corporal turn: a re-focus on the analysis and conceptualization of bodily aspects that are at the base of various cognitive capacities. Thanks to the use of analysis tools typical of the temporal arts –such as music and dance– to the field of cognitive psychology, a new form of play has been documented in early childhood: the forms of vitality play. It recovers the idea of forms of vitality from Stern (2010), which refers to affects that cannot be reflected in the lexicon of Darwinian emotions. The forms of vitality are a Gestalt, an emergent property where movement, time, force, space and directionality/ intentionality are integrated; they are a fundamental property of multimodal exchanges in the adult-baby dyad as well as of the experience, as spectator or performer, of non-figurative temporal arts such as dance and music. The forms of vitality play arise as a reconceptualization of the notion of musical play and is considered a reissue of early social play with a symmetrical participation of the child in the composition of play. It is defined as any pleasant or self-remunerative activity, in which motifs of movements and/or sounds are elaborated according to the repetition-variation form, at the expense of any figurative content. The forms of vitality play have been observed in the third year of the child’s life and it has been pointed out that it can manifest in a simple way or in combination with the pretend play. Likewise, it was suggested that when the pretend play is presented in combination with the forms of vitality play, the latter could be scaffolding the pretend play, although how this happens has not been clearly specified. The objective of the present study is to carry out a microanalysis of the sounds and movements of a pretend play scene combined with forms of vitality play of a girl of 1 year and 11 months of age and an adult, in order to know how such scaffolding is produced. The sound envelope was analyzed in order to identify and describe the timing of the sounds. Regarding movement, specialized software was used to graph its trajectory and for the analysis of the expression of movements, the basic categories “Shape and Effort” of the Laban-Bartenieff system of movement analysis were used (Laban, 1971). The results indicate the presence of interactive synchrony based on an underlying pulse that sustains mutuality between the players and provides a temporal structure on which the synchrony of the self can be anchored. Furthermore, it allows the sharing of continuity and contrast in the quality of sounds and movements and thus provides the dyad with a primary level of understanding with non-mediated meanings; promotes the exploration of the play space and the expansion of the potential of the fictional scene; it favors the maintenance of joint attention and mutual understanding through ontogenetically pre-fiction semiotic mechanisms, which favor the interactive fluidity of play.Fil: Garcia Cernaz, Santiago.

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.

Determinación del tamaño de cristalito y densidad de defectos para grafito recuperado de pilas nuevas y usadas Zn-C

Espectroscopía Raman para identificar la formación de nanocintas de carbono a partir de grafito recuperad de pilas Zn-CLa espectroscopia Raman es uno de las técnicas de caracterización más utilizados para determinar las características estructurales de materiales basados en carbono. En este trabajo, se implementa el análisis Raman para cuantificar el tamaño de cristal y la densidad de defectos del grafito recuperadas de pilas nuevas (GPN) y usadas (GPO) de Zn-C marca Panasonic®. Los resultados revelaron una alta calidad para el grafito nuevo, al presentar baja relación de intensidad (ID/IG) de 0.17, en contraste con la muestra GPO (ID/IG=0.69). La alta intensidad de las bandas D´ y D del espectro Raman de GPN, se asocian a imperfecciones en los bordes del grafito y en su estructura cristalina. El tamaño del cristalito calculado fue de 113 nm (GPN) y 27 nm (GPO), es probable que las reducciones en las dimensiones se deben a las reacciones electroquímicas de la pila. Se calculó la densidad de defectos (), el cual fue 4.881010 −2 para la muestra GPN y de 19.811010 −2 para GPO. El diminuto tamaño del cristalito de la muestra de grafito gastado (GPO), puede ser implementado en la síntesis de nanoestructuras de carbono, dado que facilita la reducción del tamaño de partícula por medios mecánicos.beca CONACyT con número 751847 Proyecto CONACYT de Ciencia Básica A1-S-3389

Integration of Dual-Arm Manipulation in a Passivity Based Whole-Body Controller for Torque-Controlled Humanoid Robots

This work presents an extension of balance control for torque-controlled humanoid robots. Within a non-strict task hierarchy, the controller allows the robot to use the feet endeffectors to balance, while the remaining hand end-effectors can be used to perform Dual-Arm manipulation. The controller generates a passive and compliance behaviour to regulate the location of the centre of mass (CoM), the orientation of the hip and the poses of each end-effector assigned to the task of interaction (in this case bi-manipulation). Then, an appropriate wrench (force and torque) is applied to each of the end-effectors employed for the task to achieve this purpose. Now, in this new controller, the essential requirement focuses on the fact that the desired wrench in the CoM is computed through the sum of the balancing and bi-manipulation wrenches. The bimanipulation wrenches are obtained through a new dynamic model that allows executing tasks of approaching the grip and manipulation of large objects compliantly. On the other hand, the feedback controller has been maintained but in combination with a bi-manipulation-oriented feedforward control to improve the performance in the object trajectory tracking. This controller is tested in different experiments with the robot TORO
