Participación argentina en procesos de integración y su influencia en el comercio internacional

El propósito de este trabajo es analizar si la participación de la Argentina en el comercio mundial, ya sea como miembro o mediante la celebración de algún acuerdo particular con algún estado o bloque, reporta beneficios económicos que pueden ser percibidos por la totalidad de la población. Este trabajo busca analizar los principales acuerdos de integración existentes en el mundo, repasando brevemente algunas de sus características e hitos de relevancia. Posteriormente se centrará en el análisis de la participación de Argentina en cada uno de los bloques en los que es miembro como así también en las relaciones, históricas o recientes, que mantiene con los bloques más importantes a lo largo del mundo.Fil: Filizzola Giunta, Fabricio.

Ameloblastomas: clinicopathological features from 70 cases diagnosed in a single Oral Pathology service in an 8-year period

Ameloblastomas are odontogenic tumors that can present some distinct clinicopathological profiles when comparing different populations and studies. Objectives: The aim of the present study was to analyze the clinicopathological features from a series of ameloblastomas diagnosed in a single Oral Pathology service in Brazil in an 8-year period. Study Design: The files were revised and all cases diagnosed as ameloblastomas in the period were retrieved. All hematoxylin and eosin stained histological slides were reviewed and all clinical and radiological information were obtained through a review of the laboratory forms. Data were descriptively analyzed and a comparison was performed with the different ameloblastomas subtypes. Results: Seventy ameloblastomas composed the final sample, including 57 (81%) solid/multicystic, 9 (13%) unicystic, 2 (3%) desmoplastic and 2 (3%) peripheral ameloblastomas. Mean age of the affected patients was in the forth decade of life and there was a slight male predominance. Most tumors presented as multilocular radiolucencies, were located in the posterior mandible and showed the follicular and plexiform histological patterns. There was no difference on the mean age of the patients affected by solid and unicystic ameloblastomas. Conclusions: The present results showed that the clinicopathological features of the ameloblastomas included in this Brazilian sample were similar to the features described in most other worldwide populations

Seismically active area monitoring by robust TIR satellite techniques: a sensitivity analysis on low magnitude earthquakes in Greece and Turkey

International audienceSpace-time TIR anomalies, observed from months to weeks before earthquake occurrence, have been suggested by several authors as pre-seismic signals. Up to now, such a claimed connection of TIR emission with seismic activity has been considered with some caution by scientific community mainly for the insufficiency of the validation data-sets and the scarce importance attached by those authors to other causes (e.g. meteorological) that, rather than seismic activity, could be responsible for the observed TIR signal fluctuations. A robust satellite data analysis technique (RAT) has been recently proposed which, thanks to a well-founded definition of TIR anomaly, seems to be able to identify anomalous space-time TIR signal transients even in very variable observational (satellite view angle, land topography and coverage, etc.) and natural (e.g. meteorological) conditions. Its possible application to satellite TIR surveys in seismically active regions has been already tested in the case of several earthquakes (Irpinia: 23 November 1980, Athens: 7 September 1999, Izmit: 17 August 1999) of magnitude higher than 5.5 by using a validation/confutation approach, devoted to verify the presence/absence of anomalous space-time TIR transients in the presence/absence of seismic activity. In these cases, a magnitude threshold (generally M In this work, 9 medium-low magnitude (

A study on the Abruzzo 6 April 2009 earthquake by applying the RST approach to 15 years of AVHRR TIR observations

A self adaptive approach (RST, Robust Satellite Technique) has been proposed as a suitable tool for satellite TIR surveys in seismically active regions devoted to detect and monitor thermal anomalies possibly related to earthquake occurrence. In this work, RST approach has been applied to 15 years of AVHRR (Advanced Very High Resolution Radiometer) thermal infrared observations in order to study the 6 April 2009 Abruzzo earthquake. Preliminary results show clear differences in TIR anomalies occurrence during the periods used for validation (15 March–15 April 2009) and the one (15 March–15 April 2008) without earthquakes with <i>M</i><sub>L</sub>≥4.5, used for confutation purposes. Quite clear TIR anomalies appears also to mark main tectonic lineaments during the preparatory phases of others, low magnitude(3.9<<i>M</i><sub>L</sub><4.6) earthquakes, occurred in the area in the same period

Blockchain tools to facilitate NFT tasks in Oasis network

Blockchain and NFT (non-fungible tokens) are topics with a growing interest, especially during the last few years. Many companies and artists have wanted to enter this world to maximize their profits from the sale of digital assets but have encountered the technological barrier of decentralization and smart contracts. This project manages to develop a collection of NFT from a number of layers of art, thus going from layers to images and metadata, then decentralizing it, and, finally, making a smart contract and a website. In addition, the project has been complemented by including two extra tools to calculate the balance and NFTs of a user's wallet. This paper explains the methodology used and the results obtained during its implementation.La cadena de bloques y los NFT (tokens no fungibles) son temas con un interés creciente, sobre todo durante los últimos años. Muchas empresas y artistas han querido adentrarse en este mundo para maximizar sus beneficios con la venta de activos digitales, pero se han encontrado con la barrera tecnológica de la descentralización y los contratos inteligentes. Este proyecto consigue desarrollar una colección de NFT a partir de un número de capas de arte, pasando así de capas a imágenes y metadatos, después descentralizándolo, y, finalmente, haciendo un contrato inteligente y una página web. Además, se ha complementado el proyecto incluyendo dos herramientas extras para calcular el balance y los NFT de la billetera de un usuario.
