A seedsnipe (Aves, Charadriiformes, Thinocoridae) from the Ensenadan Age/Stage (early-middle Pleistocene) of Buenos Aires, Argentina

The fossil record of the Charadriiformes in South America is scarce and limited to the Neogene of Argentina and Peru. In the present contribution, we present and describe a nearly complete tarsometatarsus of Thinocorus rumicivorus (Least Seedsnipe) from the Ensenadan Age/Stage (early-middle Pleistocene) of Punta Hermengo, Buenos Aires province, Argentina, which constitutes the youngest record for the species to date. We also compare the material with extant and fossil Thinocoridae. The stratigraphic range of the fossil predates the Matuyama/Brunhes boundary and is coincident with the biozone of Mesotherium cristatum, which indicates a more humid and warmer climate than the present for the species.Facultad de Ciencias Naturales y Muse

Specialized diving traits in the generalist morphology of Fulica (Aves, Rallidae)

Foot-propelled diving comprises the primary locomotion-based feeding strategy for many birds, including families such as Phalacrocoracidae, Anhingidae, Podicipedidae, Gaviidae, and the diving ducks within Anatidae. While the morphology of specialized divers is well known, the corresponding morphology is less known for birds not as specialized but capable of diving, such as the coots (Rallidae, Fulica spp.). To compare the osteology of Fulica with other (non-diving) Rallidae, and with foot-propelled diving birds that are distantly related, we considered osteological characters, as well as the proportion of the hind limb bones and the femoral splay angle to construct a phylomorphospace, and to perform a comparative disparity analysis considering ecomorphologically relevant characters related to swimming and diving. Coots resulted to be significantly disparate from other Rallidae showing many traits of specialized foot-propelled divers, but only noticeable when compared with other rallids, as the degree of development of these traits is markedly less than in loons, grebes, or cormorants. This may correspond to a stabilizing selection of characteristics associated with a generalist morphology in Fulica. Studying adaptation in generalist taxa broadens our understanding of ecomorphologically significant features, thereby enabling us to generalize their evolutionary patterns.Fil: de Mendoza, Ricardo Santiago.

Reingeniería práctica: desarrollo de un campus virtual independiente de la plataforma a partir de un campus existente

Los campus virtuales son usados como herramienta docente por alumnos y profesores. Estas herramientas se suelen utilizar para gestionar material docente. Sin embargo, cada plataforma tiene una interfaz muy diferenciada de las demás. Estas interfaces dependen por completo de un Learning Management System (LMS) complementado por un conjunto de aplicaciones que automatizan ciertos procesos de carga de datos no soportados por los LMSs (Huertas & Navarro, 2015). El objetivo de este proyecto era rediseñar por completo la interfaz de un campus virtual capaz de abstraer las distintas plataformas que estén por debajo, y de esta manera tener un único campus virtual, con la misma interfaz. Además se ha llevado a cabo un proceso de reestructuración de este campus, no solo de la interfaz, sino también de toda la estructura de negocio. Este proceso facilitará futuras mejoras y extensiones. Tras todo este proceso el resultado es un campus virtual que es independiente de la plataforma que se despliegue por debajo, con una estructura multicapa

Study of the vegetation series of Cuenca de Pamplona-Valdizarbe (Navarre-NE Spain): interest of their mapping and application

Se estudian las series y subseries de vegetación de 77.817 ha del centro de Navarra, para su cartografía a escala 1:25.000. Las series y subseries son indicadoras de las características ecológicas del territorio y complementan la información climática disponible. Se han descrito ocho series de vegetación, dos geoseries y dos complejos de vegetación. Las series climatófilas comprenden 28 faciaciones, reconocidas mediante las comunidades vegetales que las integran. La distinción de las faciaciones no sólo está asociada a factores climáticos, sino también a factores geomorfológicos, litológicos, edáficos e históricos. Estos últimos factores permiten reconocer patrones complejos a escalas de detalle, superpuestos a los que reflejan los factores climáticos, evidentes a escalas más reducidas. El estudio se enmarca en un proyecto que pretende definir la potencialidad del territorio para diferentes usos y elaborar modelos de evaluación de tierras en Navarra utilizando las unidades cartográficas reconocidas.The vegetation series and subseries of 77,817 ha of Central Navarre are studied to be used as mapping units of a vegetation series map at scale 1:25,000. The series and subseries are indicators of the land environmental features and may be useful to complete the available climatic data. Eight vegetation series, two geoseries and two vegetation complexes have been described. Climatophilous series include 28 subseries defined by the different plant communities that form each one. While vegetation series show clearly climatic patterns when studied at small scales, at detailed scales the vegetation patterns show also the effects of landforms, lithology, soils and history. This study is part of a project that is intended to assess land suitability for different uses and to work out land evaluation models in Navarre based upon the recognized mapping units

Design and Validation of A Modular Instrument to Measure Torque and Energy Consumption in Industrial Operations

A modular torque measuring instrument capable of performing tapping torque tests (TTT) according to the ASTM D-5619 standard was designed, developed, and validated. With this new instrument, the performance of different lubricants can be evaluated in terms of frictional torque and energy consumption during tapping processes. This instrument can adapt onto any conventional milling machine or CNC machine and operate under various machining operations such as tapping, drilling, and other processes. To validate the design and performance of this new device, three commercially available lubricants were evaluated. From the three tested conditions, the results showed good repeatability, with consistent results throughout the different tests for each lubricant. The impact of such a proposed instrument ranges from academic use to industrial business use

Influence of carbon source and concentration on the in vitro development of olive (Olea europaea L.) zygotic embryos and explants raised from them

6 pages, 5 tables, 33 references.The influence of sucrose or mannitol on in vitro zygotic embryo germination, seedling development and explant propagation of olive tree (Olea europaea L.) was compared. Embryos germinated without sucrose in the medium but for adequate development of the seedlings to yield viable plants, a carbohydrate supply was necessary; both sucrose and mannitol were equally suitable for this purpose. However, when explants obtained from in vitro germinated embryos were cultured with mannitol or sucrose, then the polyalcohol promoted significantly more growth than sucrose by increasing shoot length, pairs of leaves formed, and breaking apical dominance. This improved the in vitro culture of olive plant material, thus allowing new olive clonal lines to be obtained in shorter times. This will assist in future breeding experiments with the species.Peer reviewe

Hydroxyapatite biobased materials for treatment and diagnosis of cancer

Great advances in cancer treatment have been undertaken in the last years as a consequence of the development of new antitumoral drugs able to target cancer cells with decreasing side effects and a better understanding of the behavior of neoplastic cells during invasion and metastasis. Specifically, drug delivery systems (DDS) based on the use of hydroxyapatite nanoparticles (HAp NPs) are gaining attention and merit a comprehensive review focused on their potential applications. These are derived from the intrinsic properties of HAp (e.g., biocompatibility and biodegradability), together with the easy functionalization and easy control of porosity, crystallinity and morphology of HAp NPs. The capacity to tailor the properties of DLS based on HAp NPs has well-recognized advantages for the control of both drug loading and release. Furthermore, the functionalization of NPs allows a targeted uptake in tumoral cells while their rapid elimination by the reticuloendothelial system (RES) can be avoided. Advances in HAp NPs involve not only their use as drug nanocarriers but also their employment as nanosystems for magnetic hyperthermia therapy, gene delivery systems, adjuvants for cancer immunotherapy and nanoparticles for cell imaging.Peer ReviewedPostprint (published version
