Hardware Reuse Improvement through the Domain Specific Language dHDL.

The dHDL language has been defined to improve hardware design productivity. This is achieved through the definition of a better reuse interface (including parameters, attributes and macroports) and the creation of control structures that help the designer in the hardware generation process

El sistema de ventas y régimen de arrendamientos de tierras en Cáceres en el siglo XVI

Las escasas ventas de tierra que se producen en el siglo XVI, se refieren a tierras de pequeña extensión —una, dos o cuatro fanegas— las hemos considerado motivadas por una necesidad acuciante del vendedor. El estudio de la relación contractual entre comprador y vendedor, nos ha permitido comprobar que las ventas de tierra se realizan, por regla general, libres de carga pero, la modificación del léxico empleado por el escribano a partir de 1557, parece indicar la existencia de préstamos hipotecarios sobre la propiedad territorial. La sistematización de los precios nos hizo detectar las variables influyentes que actúan como elementos en la composición del precio total. En relación con los arrendamientos, pudimos extraer una tipología que ordenamos en cuatro grupos distribuidos en dos grandes apartados: arrendamientos de dehesas enteras y arrendamientos de tierras parceladas. El estudio evolutivo de los precios lo hemos agrupado en décadas. Salvo excepciones como los de arrendamientos del aprovechamiento del granillo, experimentan un alza a lo largo del siglo XVI. Esta elevación es más acusada en la primera mitad del siglo que en la segunda. El examen nominal de los contratos de arrendamiento nos ha permitido señalar el fenómeno del subarriendo. En general, es la nobleza cacereña la que arrienda las dehesas a grandes ganaderos que provienen del exterior extremeño y, éstos, son quienes las subarriendan a los pequeños ganaderos o agricultores cacereños. Un segundo tipo de subarriendo es el que se produce en los arrendamientos de tierras de labor: el propietario, casi siempre un noble, arrienda una dehesa a un arrendatario que a su vez la parcela y subarrienda a convecinos. En este proceso únicamente intervienen cacereños

Measuring the desire for control: a Spanish version of Burger and Cooper's Scale

The following study will present findings on the validity of the adaptation of the Burger and Cooper’s Desirability of Control Scale into Spanish. Two samples are present: the first involving 1,999 people to study their psychometric properties. In the second sample, 111 people were included to estimate test/ retest reliability. Cultural adaptation was performed using the translation & back-translation method. Item analysis, internal consistency and test/retest reliability were assessed, then evidence of the validity of the internal structure was determined by using exploratory and confirmatory factor analysis. Subject recruitment was performed to gather the 1,999 subjects stratified by age, gender quotas as designed in the sampling plan. Of the subjects, 51% were female, average age of 45 years old (SD = 17.5). All items from the original scale were understood correctly, while five items presented ceiling effect. Cronbach’s alpha = .736 and a test-retest correlation r = .713 were obtained. The factor structure indicated the presence of four dimensions: forecast, autonomy, power and influence and reactance which were reassured in the confirmatory analysis (χ2/df = 4.805, CFI =.932, TLI =.954, RMSEA = .062). The basic dimensions of the scale have shown to be stable and well-defined, though not perfect. The scope, possible applications of the scale and further research are later proposed and discussed.Se presenta la adaptación y validación al español de la Escala de Deseo de Control de Burger y Cooper. Se emplearon dos muestras. Para estudiar las propiedades psicométricas de la escala se contó con una primera muestra de 1999 (Medad = 45 años, DS = 17,5; 51% mujeres). Para estimar la fiabilidad test-retest se contó con una segunda muestra de 111 personas. La adaptación cultural se llevó a cabo mediante el procedimiento de traducción–retrotraducción. Se presentan las evidencias de validez de la estructura interna de la escala mediante los resultados de sendos análisis factoriales, exploratorio y confirmatorio. El análisis de ítems reveló que todos los elementos presentaron unos valores aceptables, aunque cinco de ellos mostraron efecto techo. El Alfa de Cronbach fue de .736 y la Fiabilidad test–retest fue de .713. La estructura factorial indicó la presencia de cuatro dimensiones: previsión, autonomía, poder e influencia y reactancia. La estructura fue corroborada en el análisis confirmatorio (χ2/df = 4.805, CFI = .932, TLI = .954, RMSEA = .062). Las dimensiones de la escala son estables y específicas, aunque no perfectas. Se discute el alcance y posibles aplicaciones de la escala y se proponen futuras investigaciones

Improving Hardware Reuse through XML-based Interface Encapsulation

This work proposes an encapsulation scheme aimed at simplifying the reuse process of hardware cores. This hardware encapsulation approach has been conceived with a twofold objective. First, we look for the improvement of the reuse interface associated with the hardware core description. This is carried out in a first encapsulation level by improving the limited types and configuration options available in the conventional HDLs interface, and also providing information related to the implementation itself. Second, we have devised a more generic interface focused on describing the function avoiding details from a particular implementation, what corresponds to a second encapsulation level. This encapsulation allows the designer to define how to configure and use the design to implement a given functionality. The proposed encapsulation schemes help improving the amount of information that can be supplied with the design, and also allow to automate the process of searching, configuring and implementing diverse alternatives

Sexual abuse vs. sexual freedom? A legal Approach to the Age of Sexual Consent in Adolescents in Spanish-Speaking Countries

Child and adolescent sexual abuse (CSA) is an international public health problem. Despite the importance of CSA, there is no consensus definition, and the lack of consensus is related to difficulties in conducting prevalence studies as well as research in other areas. To establish a consensual definition, legal aspects such as the age of sexual consent and the difference in age or power between victim and aggressor as well as aspects related to sexual freedom and sexual indemnity must be considered. Therefore, the main goal of this research was to analyze the age of sexual consent in the legal systems of Spanish-speaking countries and to examine whether the Romeo and Juliet clause is established. To achieve the proposed aims, we employed the legal interpretation method, and we analyzed the current Criminal Codes of the 21 Spanish-speaking countries. From the results, it is found that the age of sexual consent varies between countries, establishing valid sexual consent between 13 and 18 years. In addition, only six countries have the Romeo and Juliet clause that protects sexual freedom in adolescents. Finally, we discussed the lack of consensus on the age of sexual consent and the limitations presented by the Romeo and Juliet clause

Comparing Sports broadcasting: tracing the style of football telecast in Saudi Arabia, England and Spain

La Federación Internacional de Fútbol Asociación (FIFA) vela para que el desarrollo del fútbol como deporte resulte lo más homogéneo posible en todo el planeta. Aún así, jugadores, técnicos, público y estadios de diferentes latitudes conforman competiciones bien distintas. El telespectador aficionado, utilizando las posibilidades de la globalización mediática, puede contemplar muestras muy variadas en su pantalla y, en ocasiones, será capaz de distinguir singulares formas de poner en pantalla los partidos. Hace ahora cuarenta años, algunos académicos se planteaban si era posible reconocer indicios de estilo en la realización de los deportes y, en concreto en el caso del fútbol, confrontaban las prácticas de producción alemanas y británicas. Para actualizar similares objetivos, se han escogido partidos representativos de las ligas de fútbol de Arabia Saudí, Inglaterra y España disputados las temporadas 2013-14 y 2014-15, y se han comparado distintos tramos plano a plano. Pese al desarrollo de tecnologías y técnicas, sorprende constatar que algunas de las conclusiones de estos estudios —como las de Brien R. Williams— no pierden vigencia, y que es posible detectar algunas diferencias que explicitan puntos de vista del fútbol distintos.The International Federation Football Association (FIFA) takes over the most homogeneous developing of football as a sport across the world. Even so, players, coaches, audiences and different latitudes stages, shape very different competitions. Sport viewers, using the Media globalization possibilities, are able to distinguish different ways of showing football matches on screen. Forty years ago, Image scholars wondered whether it was possible to recognize signs of style in directing sports, and specifically in the case of football, confronting German and British broadcasting practices. Updating the same objectives, some representative matches of the saudi arabian, spanish and english league have been chosen from the 2013-14 and 2014-15 seasons, and have been compared shot by shot. Despite the development of technologies and techniques, the conclusions of researchers like those of Brien R. Williams are still operative, and it is possible to detect some differences that make explicit and distinct points of view about football

Anthocyanins and total phenolic compounds from pigment extractions of non-native species from the Umia river basin: Eucalyptus globulus, Tradescantia fluminensis, and Arundo donax

Alien invasive species (AIS) and non-native species are a prominent and extended problem in a wide range of areas in Europe and around the world. Centered in the Umia’s riparian forest, in Galicia, we found at least three main AIS needing to be controlled and harvested to preserve the biodiversity of the area. Previous studies probed that leaves and bark of selected species—Tradescantia fluminensis, Arundo donax, and Eucalyptus globulus—have important antioxidant properties, suitable for use in pharmaceutical and industrial contexts. A comparison of four solid-liquid extraction methods—Soxhlet extraction, ultrasound assisted extraction, thermal agitator, and infusion—was conducted in order to define the most efficient method in correlation within antioxidant (anthocyanins and total phenols) extraction. Water was selected as solvent, providing a sustainable research background without implying any chemical additives. The best extraction yields were obtained with Soxhlet extraction for all raw matter, with best results for Tradescantia fluminensis (41.89%) and Eucalyptus globulus leaves (39.35%); followed by the ultrasonic assisted extraction method, with better yield performed with Eucalyptus leaves (27.07%). On the contrary, Tradescantia fluminensis showed better efficiency with thermal agitator (35.07% compared to 23.19% from ultrasound extraction). After extractions, identification and quantification of total phenolic compounds and anthocyanins were carried out using spectrophotometric determination and acid hydrolysis in butanol method. In general, the best extraction yield in correlation with higher antioxidant content was performed by thermal agitator method, and Eucalyptus globulus leaves were demonstrated to be the better anthocyanins (6.18 ± 0.82 mg CC/g) and total phenols containers (172.40 ± 44.53 mg GAE/g). Studies provided promising possibilities for the residues of the three non-native species analyzed, as a source of antioxidants, favoring circular economy systems, as well as taking care of biodiversity in affected environments.Xunta de Galicia | Ref.

Characterization of cellulose derived from invasive alien species plant waste for application in the papermaking industry: physic-mechanical, optical, and chemical property analysis

This study examines the potential of four invasive plant species, both arboreal and herbaceous, within the riparian forest of the Umia River in Galicia, a common ecosystem in northern Spain. These invasive species (Arundo donax, Phytolacca americana, Eucalyptus globulus, and Tradescantia fluminensis) were collected and assessed for their suitability as an alternative source of pulp and paper materials for the paper industry to mitigate the environmental impacts associated with conventional cellulose fiber production from harmful monocultures. Cellulosic material from leaves, bark, and/or stems of each of the selected species was isolated from lignin and hemicelluloses through kraft pulping processes. Resulted fibers and pulps were analyzed visually, morphologically, chemically, and mechanically to evaluate their papermaking properties. To compare these properties with those of commercially available pulp, test sheets were concurrently produced using commercial bleached Eucalyptus cellulose. The findings reveal that the employed fibers exhibit promising characteristics for artistic paper production. Regarding the pulp, two refining times were tested in a PFI machine, and the Schopper–Riegler degree was measured. Paper sheets underwent various tests to determine thickness, basis weight, apparent volume, apparent density, permeability, and chemical composition, as well as microscopic optical and morphological properties. The fibers obtained from the waste derived from the removal of invasive exotic species and biodiversity control present a viable and intriguing alternative for decentralized paper production, yielding noteworthy results for the creative sector. This research highlights the potential of harnessing invasive species for sustainable and innovative paper manufacturing practices.Universidade de Vig

Thalassiosira pseudonana and Skeletonema costatum biomass optimization: cultivation, harvesting, extraction of oils and biodiesel and pelletization of the residue

Financiado para publicación en acceso aberto: Universidade de Vigo/CISUGMicroalgae are one of the most promising feedstocks for biofuel production that can solve the energy crisis, climate change, and the depletion of fossil fuels. Biorefineries have production capacity bottlenecks that prevent them from being economically profitable, without leaving aside the environmental safety of by-products. This research aims to analyze critical stages such as harvesting or lipid extraction from two microalgae species currently unknown, such as Thalassiosira pseudonana and Skeletonema costatum. Inorganic flocculation with a low concentration of iron or aluminum salts (FeCl3 and Al2(SO4)3) was achieved to recover >60% biomass in just 20 min in both cases. Lipids extractions through chloroform: methanol (solvent ratio 2:1) obtained low performance due to the ionic strength medium. The fatty acid composition of the algae extracts showed that stearic acid (C18:0) and palmitoleic acid (C16:1) were predominant in both species. In addition, residues from the lipid extraction process were used for the manufacture of pellets. The data collected showed that these solid biofuels should be combined with other biomass typologies if the end-use are biomass boilers. The development of these studies provides new information on different microalgae species and their potential to use their biomass through an integrated utilization
