Representation of Banach lattices as L1w spaces of a vector measure defined on a δ-ring

In this paper we prove that every Banach lattice having the Fatou property and having its s-order continuous part as an order dense subset, can be represented as the space L1 w(n) of weakly integrable functions with respect to some vector measure n defined on a d-ring.Ministerio de Educación y Ciencia MTM2009-12740-C03-02Universitat Politécnica de Valéncia PAID-10 Ref. 214

Size-Controlled Water-Soluble Ag Nanoparticles

Ag nanoparticles of two different sizes (1 and 4 nm) were prepared within an apoferritin cavity by using an Ag+-loaded apoferritin as a nanoconfined environment for their construction. The initial amount of Ag' ions injected in the apoferritin cavity dictates the size of the final Ag particles. The protein shell prevents bulk aggregation of the metal particles, which renders them water soluble and extremely stable

A photometric study of Be stars located in the seismology fields of COROT

Context. In preparation for the COROT mission, an exhaustive photometric study of Be stars located in the seismology fields of the mission has been performed. The very precise and long-time-spanned photometric observations gathered by the COROT satellite will give important clues on the origin of the Be phenomenon. Aims. The aim of this work is to find short-period variable Be stars located in the seismology fields of COROT, and to study and characterise their pulsational properties. Methods. Light curves obtained at the Observatorio de Sierra Nevada, together with data from Hipparcos and ASAS-3 for a total of 84 Be stars, were analysed in order to search for short-term variations. We applied standard Fourier techniques and non-linear least-square fitting to the time series. Results. We found 7 multiperiodic, 21 mono-periodic and 26 non-variable Be stars. Short-term variability was detected in 74% of early-type Be stars and in 31% of mid- to late-type Be stars. We show that non-radial pulsations are more frequent among Be stars than in slow-rotating B stars of the same spectral [email protected]; [email protected]

Traditión and innovation along the 2nd Millennium B.C. in the central Guadalquivir region: I. The funerary rituals

Una cultura debe contener un conjunto de items normalizados que nos permitan reconocerla en su extensión territorial, y por sus cambios, establecer su secuencia interna. Con este argumento trataremos los yacimientos arqueológicos, ya clásicos en el valle bético; en este trabajo valoraremos las necrópolis y analizaremos en otro momento la secuencia de los poblados, durante el II milenio a.C., empleando como criterio organizador la cronología, fundamentalmente la absoluta, cuando ello sea posible.Ancient cultures must hold an ensemble of normalized items, which allow us to locate it in its territorial area and, leaning on its changes, to establish its sequence. According to this argument we will consider main archaeological sites in Andalusian Valley. In this essay we will assess necropolis and analyze the village’s sequence during II B.C. using dating as organizing criteria, absolute dating when possibl

Hsp90 activity is necessary to acquire a proper neuronal polarization

Chaperones are critical for the folding and regulation of a wide array of cellular proteins. Heat Shock Proteins (Hsps) are the most representative group of chaperones. Hsp90 represents up to 1-2% of soluble protein. Although the Hsp90 role is being studied in neurodegenerative diseases, its role in neuronal differentiation remains mostly unknown. Since neuronal polarity mechanisms depend on local stability and degradation, we asked whether Hsp90 could be a regulator of axonal polarity and growth. Thus, we studied the role of Hsp90 activity in a well established model of cultured hippocampal neurons using an Hsp90 specific inhibitor, 17-AAG. Our present data shows that Hsp90 inhibition at different developmental stages disturbs neuronal polarity formation or axonal elongation. Hsp90 inhibition during the first 3. h in culture promotes multiple axon morphology, while this inhibition after 3. h slows down axonal elongation. Hsp90 inhibition was accompanied by decreased Akt and GSK3 expression, as well as, a reduced Akt activity. In parallel, we detected an alteration of kinesin-1 subcellular distribution. Moreover, these effects were seconded by changes in Hsp70/Hsc70 subcellular localization that seem to compensate the lack of Hsp90 activity. In conclusion, our data strongly suggests that Hsp90 activity is necessary to control the expression, activity or location of specific kinases and motor proteins during the axon specification and axon elongation processes. Even more, our data demonstrate the existence of a >time-window> for axon specification in this model of cultured neurons after which the inhibition of Hsp90 only affects axonal elongation mechanisms. © 2013 Elsevier B.V.Peer Reviewe

Cinemática rotacional del cabalgamiento basal surpirenaico en las Sierras Exteriores Aragonesas: Datos magnetotectónicos

The magnetotectonic analysis of 32 sites located along the External Sierras (mainly in Middle Eocene marls) shows the primary character of the magnetisation and pennits the differences between the paleovectors obtained to be interpreted as a result of the rotational kinematics of the southpyrenean floor thrust in the study area. The constancy of the directions of the defined unblocking intervals (300"-425°C for the thermal treatment) and the homogeneity of the magnetic carriers (these were always low coercitivity phases, probably sulphides andlor magnetite) prove the stability of the magnetisation. On the other hand, the primary character of the magnetisation (Middle Eocene) can be demonstrated by: a) the constancy of the magnetic inclination (47.3 +/- 1.7) and its similarity with the reference direction; b) the occurrence of reversals, and the positive result of the fold-test made in the Pico del Águila anticline; c) the consistency between the reference direction (DEC = 005", INC = 51°, a95=6 ") and the direction obtained for the authocthonous footwall (DEC = 005", INC = 38", a95= 8") which crops out in the western sector of the Sierras Exteriores thrust front. The interpretation of the paleomagnetic data within the External Sierras structural framework clearly shows that the kinematics of individual thrust sheets involves a clockwise component, at least during a period of their evolution. The maximum rotation values were found in the western and central sectors (42" and 30" respectively). The age of the rotation decreases towards the west along with the age of deformation of the cover rocks. Starting in late Priabonian the kinematics of the thrust front resulted in a lack of rotation in the central sector of the Sierras, while the western sector undenvent a clockwise rotation. The differential movement between both sectors gave rise to the development or reactivation of structures (i. e. Rasal-Anzáñigo anticlines) that articulated the deformation of adjacent zones with different rotational components

Optical sensor to determine plant spacing for precise application

Congreso Agroingeniería 2015. Orihuela (Alicante). 1 a 3 de junio de 2015La automatización en el manejo de la mala hierba de forma individualizada está siendo una realidad cada vez más cercana, tanto objetivos de eficiencia como de beneficio económico se están consiguiendo. En un futuro muy próximo la mecanización y su diseño tendrá que contemplar técnicas de monitorización o detección de precisión. El objetivo de este estudio fue evaluar la capacidad de un sensor óptico para determinar el espacio entre las plantas de una misma línea de cultivo en diferentes condiciones: laboratorio y campo. Este equipo de trabajo ha investigado la detección del cultivo con un sensor fotoeléctrico de infrarrojo (880 nm) en modo opuesto. La barrera fotoeléctrica de transmisión, usa un par de sensores y al paso de la planta por la cortina de luz interrumpe el haz. La señal de luz se recibe de forma simultánea en tiempo real mediante un sistema de control de alta velocidad. El sensor fotoeléctrico fue capaz de detectar la planta de tomate y por tanto de terminar la separación entre ellas de forma muy precisa. El uso de sistemas de detección como este puede dar lugar a una nueva era que permita el control en la línea de cultivo de la mala hierba de forma más económica y a la automatización de la operación. El control preciso de la mala hierba es un reto importante para este grupo, por ello tenemos previsto seguir trabajando en esta línea.Automation of individual crop plant care in commercial vegetable crop fields has increased practical feasibility and improved efficiency and economic benefit. Its systems approach is taken in the mechanization engineering design by the incorporation of precision sensing techniques. The objective of this study was design-sensing capabilities in an implement for measuring plant spacing under different test conditions: laboratory and field. For that proposal, a photoelectric transmission barrier, by using an optical light curtain transmitter and receiver, evaluated the interruption by the tomato stem of the light curtain, being recorded simultaneously in real-time by a high-speed embedded control system. The optical sensor provided tomato plant detection and therefore the spacing between tomato plants was determined with accuracy. The use of this detection system may result in a new era that allow for an online control of aggressive weeds and the automation of weeding tools, which we plan to pursue through future research.Junta de Andalucía P12-AGR-122
