On the Krein–Milman Property and the Bade Property

AbstractThroughout this paper a study on the Krein–Milmam Property and the Bade Property is entailed reaching the following conclusions: If a real topological vector space satisfies the Krein–Milmam Property, then it is Hausdorff; if a real topological vector space satisfies the Krein–Milmam Property and is locally convex and metrizable, then all of its closed infinite dimensional vector subspaces have uncountable dimension; if a real pseudo-normed space has the Bade Property, then it is Hausdorff as well but could allow closed infinite dimensional vector subspaces with countable dimension. On other hand, we show the existence of infinite dimensional closed subspaces of ℓ∞ with the Bade Property that are not the space of convergence associated to any series in a real topological vector space. Finally, we characterize unconditionally convergent series in real Banach spaces by means of a new concept called uniform convergence of series

Estudio de la anteversión femoral

Se estudian los valores angulares de la anteversión femoral en 30 fémures humanos secos normales, del lado izquierdo y pertenecientes a individuos adultos. Los valores angulares de la muestra son sometidos a estudio estadístico dando una fiabilidad de la media para p = 0,01 . Se revisa la bibliografía de otras mediciones realizadas en hueso seco y se comparan con los valores obtenidos en este trabajo. Los valores obtenidos contribuirán a un mejor conocimiento del ángulo de anteversión femoral y consecuentemente a la aplicación clínica del mismo

Data aggregator implemented through industrial gateway IOT 2050 for smart microgrid

[EN] This paper describes the operation and implementation of a Data Aggregator based on an Industrial Gateway (DAIG) for the storage and transmission of information from an experimental Smart microgrid hybridised with green hydrogen. This DAIG consists of a Siemens IOT 2050, a commercial device that combines physical characteristics such as robustness and open-source software. To achieve this objective, each subsystem involved in the microgrid has a set of sensors and a Data Acquisition Device (DAD) to obtain the relevant logical magnitudes of its operation. The IOT 2050 serves as a centralised system, communicating via Modbus TCP/IP with each DAD and storing the data read in a local database by means of a Python script. Finally, as an example of the application of the designed infrastructure, an IoT software is implemented to visualise the data stored in the DAIG

Characterization of digestive protease activity in the bluefin tuna Thunnus thynnus (Linnaeus, 1758)

The digestive proteases of bluefin tuna Thunnus thynnus (Linnaeus, 1758) were studied. Protease activity in stomach extracts showed two optima, at pH 2.0 and 3.5. Optimum activity for intestinal proteases was found at pH 10.0 and 12.0. Protease activity in stomach extracts was found to be stable at several pH, except for pH 12.0. Alkaline protease activity of intestine extracts was highly sensitive to acidic pH. Optimal temperatures found were 50 ºC for acid proteases and 60 ºC for alkaline proteases. The use of specific protease inhibitors indicated that the main presence of acid proteases was in stomach extracts, and serine proteases in intestine extracts. Active fractions in extracts were identified with SDS-PAGE.Se estudió la actividad proteasa digestiva de Thunnus thynnus (Linnaeus, 1758). Se encontraron dos óptimos de pH, tanto para la actividad proteasa ácida de los extractos estomacales (2,0 y 3,5) como para la actividad proteasa alcalina de los intestinales (10,0 y 12,0). La primera se mantuvo muy estable en un rango amplio de pH, a excepción de pH muy alcalinos (12,0). Por su parte, la actividad proteasa alcalina se vio afectada por pH muy ácidos. Los óptimos de temperatura se determinaron en 50 y 60 ºC para la actividad proteasa ácida y alcalina, respectivamente. Mediante el uso de inhibidores de proteasa se comprobó la presencia de proteasas aspárticas en los extractos estomacales y de serin-proteasas en los intestinales. La realización de zimogramas permitió identificar las distintas fracciones con actividad proteolítica presentes en cada extracto.Instituto Español de Oceanografí

Síndrome del tunel carpiano

La compresión del nervio mediano o síndrome del túnel carpiano es la neuropatía por atrapamiento más frecuente. Presenta unos síntomas -y en ocasiones unos signos- característicos que es preciso recordar. La etiología es multifactorial –anatómica, sistémica, ocupacional laboral, etc.-. El diagnóstico se basa en la anamnesis, exploración física y confirmación electromiográfica. Su cronicidad conlleva a una reactivación de la clínica y menoscabo funcional. La amplia fisiopatología, frecuencia y tratamientos conservadores entre ellos la inmovilización, el rehabilitador –programa de fisioterapia de deslizamiento nervioso-, la infiltración corticoidea i.e., son resolutivos. La cirugía se reserva como terapia liberadora cada vez menos invasiva en sus diversas técnicas. Presentamos una técnica de miniincisión, de corta cicatriz, con rápida recuperación clínica y laboral, baja morbilidad y riesgos limitados, en comparación con la técnica clásica abierta y la endoscópica.Carpal tunnel syndrome is the most common compressive neuropathy of the upper extremity. As a result of median nerve compression, the patient reports pain, weakness, and paresthesias in the hand and fingers. The etiology of this condition is multifactorial: anatomic, systemic, and occupational factors have all been implicated. The diagnosis is based on the patient history, physical examination and is confirmed by electrodiagnostic testing. Treatment methods range from observation and splinting; workplace task modification and wrist splints can reduce or defer referral to hospital for surgical decompression. Nerve and tendon gliding exercises may also be of benefit. The short-incision we present, also called mini-open, may allow for quicker recovery time, minimal scar, no tenderness, low morbidity, while avoiding some of the complications of endoscopy and than with the open approach, found in the few article

Late-Variscan multistage hydrothermal processes unveiled by chemical ages coupled with compositional and textural uraninite variations in W-Au deposits in the western Spanish Central System Batholith

The scheelite skarn from Los Santos and the W-Au veins from El Cabaco district, located in the Spanish Central System Batholith (SCSB), are some of the best-known tungsten ore deposits in Spain. Uraninite is an accessory mineral in both deposits, which underwent several hydrothermal flow events. Chemical and textural characteristics, as well as electron microprobe U-Th-Pb uraninite chemical data from the different stages of the skarn and the vein-type mineralizations, are presented here. Based on these data the uraninite was able to be classified into two groups. Group I uraninite has an octahedral habit and occurs as inclusions in K-feldspar relicts of the leucogranite related to Los Santos skarn formation. It shows high Th (6.95 to 8.51wt.% ThO2) and high Rare Earth Elements (REEs) contents (0.55 to 1.38wt.% ∑REE2O3). Group II uraninite occurs i) associated to El Cabaco granite, in a greenish selvage-style greisen and its reddish envelope and in the mineralized rimming quartz veins and ii) in Los Santos high-temperature endoskarn and anorthite skarn, where it is associated with U-rich mica. This uraninite type has lower Th and ∑REE2O3contents than Group-I uraninite. The mineral chemistry and the assemblage and textural relationships suggest that Group-I uraninite is magmatic and the attained U-Th-Pb chemical age of 300±4Ma is interpreted as the magmatic age of the skarn-forming aplite granites in the western part of the SCSB. Group-II uraninite includes two events: i) hydrothermal uraninite, which yields an age of 295±2Ma, dates a strong alkali mobilization and early tungsten deposition and ii) a later hydrothermal process, around 287±4Ma, that resulted in sulfides and late scheelite precipitation and widespread silicification. Finally, the gold deposition is younger than this silicification according to textural criteria. Therefore, W-Au deposits in the western part of the SCSB were formed by superposition of several processes that took place some 15Ma after the skarn-forming granite crystallized. Comparable W, W-Au and U deposits in the Variscan orogenic belt show a similar timing of hydrothermal events, suggesting that the hydrothermal history was controlled by large-scale Late-Variscan tectonic processes
