Some Issues on Ontology Integration

The word integration has been used with different meanings in the ontology field. This article aims at clarifying the meaning of the word “integration” and presenting some of the relevant work done in integration. We identify three meanings of ontology “integration”: when building a new ontology reusing (by assembling, extending, specializing or adapting) other ontologies already available; when building an ontology by merging several ontologies into a single one that unifies all of them; when building an application using one or more ontologies. We discuss the different meanings of “integration”, identify the main characteristics of the three different processes and proposethree words to distinguish among those meanings:integration, merge and use

Estudio clínico morfológico de la deformación del borde dorsal del cuello en caballos cruzados de carruaje en Sevilla y Córdoba (Andalucía, España)

The aim of this study was to a clinical, morphological of deformation dorsal neck edge on in horse of carriage in Seville and Cordoba, Andalusia, Spain. We studied a total of 110 horses. Clinical examination was performed and morphological considering weight and body condition was measured cervical perimeter. Deformation of the dorsal edge of the neck in all cases studied was evident. Morphological study to consider the deformation of the dorsal edge of the neck taking into account the ridge of the neck (score of 1 to 5) evidenced: for score 0: 33.6%; score 1: 51.8%; Rankings 2: 10%; Rated: 4.5 % for score 4 and 5 no horse was observed in these categories. The average diameter of the neck was 92.54cm, the average neck length was 92.46 cm and the weight was 3.92kg. The statistical result of the degree of deformation of the neck with the weight was 0.465 and the correlation between the degrees of deformation with weight was 0.652. The degree of correlation between neck circumference and body condition was 0.634. In conclusion deformation dorsal edge of the collar in horses used for carriage crossed in Cordoba and Seville, Spain, was observed a prevalence of 66%.Se plantea como objetivo un estudio clínico morfológico de la deformación del borde dorsal del cuello en caballos de carruaje en Sevilla y Córdoba, Andalucía-España. Fueron estudiados un total de 110 caballos. Se practicó un examen clínico y morfológico considerando condición corporal peso y se midió el perímetro cervical. El estudio morfológico para considerar la deformación del borde dorsal del cuello tomando en cuenta la cresta de la nuca (puntuación del 1 al 5) evidencio: para la puntuación 0: 33.6%; puntuación 1: 51.8%; puntuación 2: 10%; puntuación: 4.5%, para la puntuación 4 y 5 ningún caballo se observó en estas categorías. El promedio del diámetro del cuello fue de 92.54cm, el promedio de la longitud del cuello fue de 92.46 cm y el peso fue de 3.92Kg. Los resultados estadísticos del grado de deformación del cuello con el peso fue de 0.465 y la correlación entre el grado de deformación con el peso fue de 0.652. El grado de correlación entre el perímetro cervical y la condición corporal fue de 0.634. En conclusión se observó la deformación del borde dorsal del cuello en caballos cruzados empleados para carruajes en Córdoba y Sevilla, España, con una prevalencia puntual de 66%

Impact of invasive bees on plant-pollinator interactions and reproductive success of plant species in mixed Nothofagus antarctica forests

Invasive social bees can alter plant-pollinator interactions with detrimental effects on both partners. However, most studies have focused on one invasive bee species, while the interactions among two or more species remain poorly understood. Also, many study sites had a history of invasive bees, being hard to find sites with historical low abundances. In Patagonia, Bombus ruderatus (F.) invasion begun in 1993 and B. terrestris (L.) in 2006. Though honey bees (Apis mellifera L.) introduction started in 1859, their density is still low in some parts. By experimentally increasing honey bee densities, we evaluated the effect of honey bees and bumblebees floral visitation on native pollinator floral visitation, pollen deposition, and reproductive success of three plant species in mixed Nothofagus antarctica forests of northern Patagonia: Oxalis valdiviensis, Mutisia spinosa and Cirsium vulgare. Our results show that exotic bees became the main floral visitors. No negative association was found between invasive bee and native pollinator visitation rates, but there was evidence of potential competition between honey bees and bumblebees. Floral neighborhood diversity played an important role in pollinator behavior. Conspecific pollen deposition was high for all species, while deposition of heterospecific pollen was very high in M. spinosa and C. vulgare. Not as expected, honey bees visitation rate had a negative effect on heterospecific pollen deposition in C. vulgare. For O. valdiviensis, exotic visitation rates increased conspecific pollen deposition, which was positively related to reproductive success. Although exotic bees became main floral visitors, their contribution to reproductive success was only clear for one species.info:eu-repo/semantics/acceptedVersio

Swinging Atwood's Machine: Experimental and Theoretical Studies

A Swinging Atwood Machine (SAM) is built and some experimental results concerning its dynamic behaviour are presented. Experiments clearly show that pulleys play a role in the motion of the pendulum, since they can rotate and have non-negligible radii and masses. Equations of motion must therefore take into account the inertial momentum of the pulleys, as well as the winding of the rope around them. Their influence is compared to previous studies. A preliminary discussion of the role of dissipation is included. The theoretical behaviour of the system with pulleys is illustrated numerically, and the relevance of different parameters is highlighted. Finally, the integrability of the dynamic system is studied, the main result being that the Machine with pulleys is non-integrable. The status of the results on integrability of the pulley-less Machine is also recalled.Comment: 37 page
