A dataset of RDF licenses

rights and conditions present in licenses for software, data and general works are expressed with the Open Digital Rights Language (ODRL) 2.0 vocabulary and extensions thereof. The dataset contains licenses identified by a dereferenceable URI, which are served with content negotiation providing a double representation for humans and machines alike. This feature enables a generalized machine-to-machine commerce if generally adopted

Rights declaration in Linked Data

Linked Data is not always published with a license. Sometimes a wrong license type is used, like a license for software, or it is not expressed in a standard, machine readable manner. Yet, Linked Data resources may be subject to intellectual property and database laws, may contain personal data subject to privacy restrictions or may even contain important trade secrets. The proper declaration of which rights are held, waived or licensed is a must for the lawful use of Linked Data at its different granularity levels, from the simple RDF statement to a dataset or a mapping. After comparing the current practice with the actual needs, six research questions are posed

Papel de los herpes virus en la enfermedad periodontal. Revisión de literatura

Introducción: La periodontitis es una enfermedad multifactorial, donde las bacterias no tienen un papel único en su origen y desarrollo. Con el avance de los estudios microbiológicos se ha demostrado la presencia de los herpes virus en las diferentes manifestaciones clínicas de la misma. Objetivo: mostrar diferentes elementos en los cuales se relaciona la infección por herpes virus con el inicio y desarrollo de las periodontopatías. Material y Métodos:Se realizó una revisión bibliográfica mediante la consulta de bases de datos de los sistemas referativos, como MEDLINE, PubMed y Scielo, con la utilización de descriptores como herpes virus, citomegalovirus, Epstein-Barr virus, periodontal disease, pathogenesis. Conclusiones: Se llegó a la conclusión que las células inflamatorias infectadas con virus herpéticos provocan la producción de citocinas que destruyen los tejidos periodontales y pueden disminuir la capacidad de defensa frente a la exposición bacteriana.Palabras clave:Herpes virus, enfermedad periodontal, interacción bacterias- herpes virus </p

Burkholderia cepacia aisladas de variedades de ñame con actividad antimicrobiana contra Colletotrichum gloeosporioides

The present study had as objective in vitro to evaluate the antifungal activity of type compound antibiotic produced by isolated endophytes bacteria from varieties of yam against the mycelial growth of the fungus C. gloesporioides. Samples of Yam plants were collected randomly in the form of zig-zag in the Department of Sucre. The collected samples were disinfected surface; subsequently is led to out the isolation, counting and separation of morphotypes of endophytes bacteria through technique of serial over surface of the agar medium. Each to isolated morphotype was used to evaluate in vitro inhibitory activity of cells of endophytes bacteria on the growth of the fungus C. gloesporioides. The morphotype of bacteria with greater inhibitory activity were selected to obtain metabolites antibiotic type in two sources of carbon (glucose and mannitol) in three concentrations (0,5; 1,0 and 1,5%). The morphotype with greater inhibitory activity was 3AT1, the results of the in vitro test showed greater activity when the composite type antibiotic was obtained in the middle with a concentration of 1,5% glucose. Identification with kit API20E results confirm with a 99.9% of identity with the kind of bacterium Burkholderia cepacia, becoming this compound as a potential biological against the micelal growth of the fungus C. gloesporioides, causing the disease known as yam anthracnose in the Department of Sucre.El presente estudio tuvo como objetivo, evaluar in vitro la actividad antifúngica de compuesto tipo antibiótico producido por bacterias endófitas aisladas de variedades de ñame contra el crecimiento micelial del hongo C. gloesporioides. Las muestras plantas de ñame fueron recolectadas aleatoriamente en forma de zig-zag en los sitios de muestreo seleccionados en el departamento de Sucre. Las muestras recolectados fueron desinfectados superficialmente, posteriormente se llevó a cabo el aislamiento, conteo y separación de morfotipos de bacterias endófitas mediante técnica de dilución seriada sobre superficie del medio agar. A cada morfotipo aislado fue utilizado para evaluar in vitro la actividad inhibitoria de células de bacterias endófitas contra el crecimiento del hongo C. gloesporioides. Los morfotipos de bacterias con mayor actividad inhibitoria fueron seleccionados para la obtención de metabolitos tipo antibiótico en dos fuentes de carbono (Glucosa y manitol) en tres concentraciones (0.5; 1,0 y 1,5 %). El morfotipo con mayor actividad inhibitoria fue 3AT1, los resultados del ensayo in vitro mostró mayor actividad cuando el compuesto tipo antibiótico fue obtenido en el medio con una concentración de 1.5% de glucosa. Los resultados de la identificación con kit API20E confirman con un 99.9 % de identidad con la especie de bacteria B. cepacia, constituyéndose este compuesto como un potencial biológico contra el crecimiento micelal del hongo C. gloesporioides, causante de la enfermedad conocida como antracnosis del cultivo del ñame en el departamento de Sucre

Licensing patterns for Linked Data

Rights expression languages declare the permitted and prohibited actions to be performed on a resource. Along this work, six rights expression languages are compared, abstracting their commonalities and outlining their underlying pattern. Linked Data, which can be object of protection by the intellectual property laws or its access be restricted by an access control system, can be the asset in rights expressions. The requirements for a pattern for licensing Linked Data resources are listed

Linked Data Rights 2.0: extension of ODRL for Licensing Linked Data

Linked Data assets (RDF triples, graphs, datasets, mappings...) can be object of protection by the intellectual property law, the database law or its access or publication be restricted by other legal reasons (personal data pro- tection, security reasons, etc.). Publishing a rights expression along with the digital asset, allows the rightsholder waiving some or all of the IP and database rights (leaving the work in the public domain), permitting some operations if certain conditions are satisfied (like giving attribution to the author) or simply reminding the audience that some rights are reserved

Detection of metabolite changes in C6 glioma cells cultured with antimitotic oleyl glycoside by1H MAS NMR

The synthetic glycoside, oleyl N-acetyl-α-D-glucosaminide (1), was previously shown to exhibit antimitotic activity on rat (C6) and human (U-373) glioma lines. To obtain information about its mechanism of action, metabolite changes in C6 glioma cells were analyzed after treatment with 1 using high-resolution magic angle spinning 1H NMR. Compound 1 caused either a decrease or an increase in the intensity of the signal assigned to coenzyme A (CoA) metabolites depending on the concentration used. The data obtained from the 1H NMR spectra of cells cultured with 1, combined with those obtained after treatment with oleic acid (an inhibitor of acetyl-CoA carboxylase) and phenyl butyrate (a known antineoplastic agent), suggest that 1 may be altering the metabolism of fatty acids and induce apoptosis of C6 glioma cells. These results point to NMR spectroscopy as an efficient technique for monitoring the response of the cells to therapeutic agents.Peer Reviewe

Multi-Camera very wide baseline feature matching based on view-adaptive junction detection

This paper presents a strategy for solving the feature matching problem in calibrated very wide-baseline camera settings. In this kind of settings, perspective distortion, depth discontinuities and occlusion represent enormous challenges. The proposed strategy addresses them by using geometrical information, specifically by exploiting epipolar-constraints. As a result it provides a sparse number of reliable feature points for which 3D position is accurately recovered. Special features known as junctions are used for robust matching. In particular, a strategy for refinement of junction end-point matching is proposed which enhances usual junction-based approaches. This allows to compute cross-correlation between perfectly aligned plane patches in both images, thus yielding better matching results. Evaluation of experimental results proves the effectiveness of the proposed algorithm in very wide-baseline environments

Guidelines for Linked Data generation and publication: an example in building energy consumption

Linked Data is the key paradigm of the Semantic Web, a new generation of the World Wide Web that promises to bring meaning (semantics) to data. A large number of both public and private organizations have published their data following the Linked Data principles, or have done so with data from other organizations. To this extent, since the generation and publication of Linked Data are intensive engineering processes that require high attention in order to achieve high quality, and since experience has shown that existing general guidelines are not always sufficient to be applied to every domain, this paper presents a set of guidelines for generating and publishing Linked Data in the context of energy consumption in buildings (one aspect of Building Information Models). These guidelines offer a comprehensive description of the tasks to perform, including a list of steps, tools that help in achieving the task, various alternatives for performing the task, and best practices and recommendations. Furthermore, this paper presents a complete example on the generation and publication of Linked Data about energy consumption in buildings, following the presented guidelines, in which the energy consumption data of council sites (e.g., buildings and lights) belonging to the Leeds City Council jurisdiction have been generated and published as Linked Data
