Integration ontology for distributed database

In this work we will study the problem of the design of the "Integration Model for Distributed Database System". We particularly design the canonical model through the ontological handling of the information. The ontology is designed in a way that allows the description of a database like a set of representative terms of its different components. In this ontology, the definitions use classes, relations, functions, among other things, of databases, to describe their components, operations and restrictions, as well as, the process of integration. These databases can be Relational, Fuzzy, Intelligent and Multimedia1st International Workshop on Advanced Software Engineering: Expanding the Frontiers of Software Technology - Session 2: Software ModelingRed de Universidades con Carreras en Informática (RedUNCI

Toll-like 4 and protease-activated receptor 2 in physiology and pathophysiology of the nervous system: more than just receptor cooperation?

Toll-like receptor 4 (TLR4) and protease-activated receptor 2 (PAR2) play pivotal roles in the mammalian innate immune response. Notably, in addition to their involvement in detection of invading pathogens, PAR2 and TLR4 modulate the levels of cell death-induced sterile inflammation by activating pro- or anti-inflammatory downstream signalling cascades. Within the central nervous system, there is emerging evidence that both receptors are involved in synaptic transmission and brain plasticity. Furthermore, due to their prominent role in mediating neuroinflammation, PAR2 and TLR4 are associated with development and progression of neurodegenerative disorders including but not limited to Alzheimer`s disease (AD), Parkinson`s disease (PD) and Multiple Sclerosis. In this article, we summarise the current knowledge on the cooperation between PAR2 and TLR4, discuss the potential cross-talk levels and highlight the impact of the cross-coupling on neuroinflammation

Conocimientos de la mecanica corporal de los alumnos de la Facultad de Enfermería y Obstetricia

Considerando a la salud como una medida primordial para lograr el desarrollo económico y social que propicie el bienestar integral de cada individuo, así como de la sociedad en su conjunto, se requiere de un ejercicio interprofesional en donde cada profesional del área de la salud posee la mejor formación educativa en la que se han desarrollado tanto competencias para la búsqueda y aplicación del conocimiento, como actitudes de compromiso profesional y social (Reyes, 2015). La enfermería como profesión asumió la responsabilidad de cuidar al individuo sano o enfermo, y en su formación, ésta respondió a las diferentes épocas a las formas en que se ha concebido el proceso salud-enfermedad, a los avances de la ciencia y la tecnología, y de la misma forma al desarrollo de la planeación curricular

Breaking the Rayleigh-Plateau instability limit using thermocavitation within a droplet

We report on the generation of liquid columns that extend far beyond the traditional Rayleigh-Plateau instability onset. The columns are driven by the acoustic pressure wave emitted after bubble collapse. A high-speed video imaging device, which records images at a rate of up to 105 fps, was employed to follow their dynamics. These bubbles, commonly termed thermocavitation bubbles, are generated by focusing a midpower (275 mW) continuous wavelength laser into a highly absorbing liquid droplet. A simple model of the propagation of the pressure wavefront emitted after the bubble collapse shows that focusing the pressure wave at the liquid-air interface drives the evolution of the liquid columns. Control over the aspect ratio of the liquid column is realized by adjusting the cavitation bubble's size, beam focus position, and droplet volume. © 2013 by Begell House, Inc

Actividad antioxidante e inhibidora de a-glucosidasa y a-amilasa de tres variedades de cebolla (Allium cepa L.)

La cebolla (Allium cepa L.) ha sido cultivada durante miles de años y es utilizada como un componente importante en la dieta del ser humano. Estudios recientes sugieren que su consumo puede reducir o prevenir problemas de salud como asma, enfermedades cardiovasculares y diabetes, debido a sus efectos antioxidantes. En este estudio se determinó el contenido de compuestos fenólicos totales, la capacidad antiradical y la inhibición de las enzimas α-glucosidasa y α-amilasa de extractos acuosos y etanólicos de tres variedades de cebolla (blanca, amarilla y morada). El contenido de compuestos fenólicos totales varió de 6.59 a 9.25 mg/100 g y la actividad antiradical expresada como % DPPH- se encontró entre 20.4% a 39.6% y de 46.8 a 89.2% para los extractos acuosos y etanólicos respectivamente. Todos los extractos etanólicos fueron capaces de inhibir la actividad α-glucosidasa y α-amilasa de 58% a 34%% y 33 y 22% respectivamente, mientras que los extractos acuosos fueron menos efectivos. Entre los extractos estudiados, el extracto etanólicos de cebolla morada presenta la mayor concentración de compuestos fenólicos totales y la mayor actividad antiradical e inhibidora de α-glucosidasa. Las diferencias encontradas entre la concentración de compuestos fenólicos y las distintas actividades estudiadas parecen depender del perfil único de compuestos fenólicos que posee cada variedad de cebolla

Prevalencia de sobre peso y obesidad exogena en adolescentes de 12 a 18 años, y su asociación con dislipidemias

La presente tesis trata sobre la prevalencia del sobrepeso y obesidad exógena en los adolescentes salvadoreños entre las edades de 12 a 18 años, y como la presencia de estas puede influir en el desarrollo de dislipidemias a edades tempranas. Se realizó un estudio descriptivo, correlacional, transversal. Se estudió a 50 adolescentes comprendidos entre los 12 a 18 años, que presentaban un índice de masa corporal mayor a 25 según la clasificación de la IOTF . A todos se les peso y tallo, se midió la cincunferencia abdominal y se obtuvieron muestras de sangre por venopunción para poder obtener el colesterol total, HDL, triglicéridos. Al obtener los resultados se observó que existe una asociación entre la presencia de obesidad y dislipidemias, a partir de lo cual se realizaron conclusiones y recomendaciones sobre como disminuir la presencia de sobrepeso y obesidad en los adolescentesTesis para optar al Título de Doctor en Medicin

Quantum key distribution based on selective post-processing in passive optical networks

One of the main obstacles to the widespread adoption of quantum cryptography has been the difficulty of integration into standard optical networks, largely due to the tremendous difference in power of classical signals compared with the single quantum used for quantum key distribution. This makes the technology expensive and hard to deploy. In this letter, we show an easy and straightforward integration method of quantum cryptography into optical access networks. In particular, we analyze how a quantum key distribution system can be seamlessly integrated in a standard access network based on the passive optical and time division multiplexing paradigms. The novelty of this proposal is based on the selective post-processing that allows for the distillation of secret keys avoiding the noise produced by other network users. Importantly, the proposal does not require the modification of the quantum or classical hardware specifications neither the use of any synchronization mechanism between the network and quantum cryptography devices

Controllable direction of liquid jets generated by thermocavitation within a droplet.

A high-velocity fluid stream ejected from an orifice or nozzle is a common mechanism to produce liquid jets in inkjet printers or to produce sprays among other applications. In the present research, we show the generation of liquid jets of controllable direction produced within a sessile water droplet by thermocavitation. The jets are driven by an acoustic shock wave emitted by the collapse of a hemispherical vapor bubble at the liquid-solid/substrate interface. The generated shock wave is reflected at the liquid-air interface due to acoustic impedance mismatch generating multiple reflections inside the droplet. During each reflection, a force is exerted on the interface driving the jets. Depending on the position of the generation of the bubble within the droplet, the mechanical energy of the shock wave is focused on different regions at the liquid-air interface, ejecting cylindrical liquid jets at different angles. The ejected jet angle dependence is explained by a simple ray tracing model of the propagation of the acoustic shock wave inside the droplet

"Capital Stock and Unemployment: Searching for the Missing Link"

The purpose of this paper is to examine the proposition that capital stock relative to aggregate output has been an important variable in the determination of the U.S. NAIRU (Non-Accelerating Inflation Rate of Unemployment) over the last four decades. We present new empirical evidence, obtained from the application of the cointegrated VAR methodology to U.S. time-series data, that lends strong support to the claim that the aggregate capital-output ratio, the real price of imports, and aggregate capacity utilization were determinants of the NAIRU in the period considered. The same evidence also shows that technical progress and changes in long-term unemployment did not affect the NAIRU. We believe this evidence suggests that, insofar as the aggregate capital-output ratio is affected by changes in real interest rates, the stance of monetary policy is one determinant of the NAIRU.
