Seguidors vencen, un grito de guerra para un rey: Un lema para la virtud de la Fortaleza en Alfonso V el Magnánimo (1423-1458)
2017
espanolLa historia politica de Alfonso V el Magnanimo, Rey de Aragon (1416-1458) permanece asociada, indefectiblemente, a sus derechos sobre el trono de Napoles. Las vicisitudes que vivio desde 1423, cuando Juana II Durazzo lo destituyo como heredero del mismo, hasta lograrlo en 1442, motivaron toda una serie de elementos representativos con los que el soberano busco legitimarse ante sus subditos y contemporaneos. De entre ellos, reclama la atencion el posible uso que el monarca hizo del lema “Seguidors vencen”. El estudio de dicho mote y su posible asociacion al emblema real del Siti Perillos constituyen el objeto del presente articulo. EnglishThe political history of Alfonsus V the Magnan…
Multi-model ensemble simulations of olive pollen distribution in Europe in 2014: current status and outlook
2017
"Çalışmada 29 yazar bulunmaktadır. Bu yazarlardan sadece Bursa Uludağ Üniversitesi mensuplarının girişleri yapılmıştır” The paper presents the first modelling experiment of the European-scale olive pollen dispersion, analyses the quality of the predictions, and outlines the research needs. A 6-model strong ensemble of Copernicus Atmospheric Monitoring Service (CAMS) was run throughout the olive season of 2014, computing the olive pollen distribution. The simulations have been compared with observations in eight countries, which are members of the European Aeroallergen Network (EAN). Analysis was performed for individual models, the ensemble mean and median, and for a dynamically optimised c…
Organized assemblies of magnetic clusters
2003
Abstract In this work we have explored the possibilities to create layered organizations of the Mn 12 single-molecule magnets using the Langmuir–Blodgett technique or attaching these clusters onto a metal surface by preparing self-assembled monolayers (SAMs). In the first part we discuss the use of the Langmuir–Blodgett (LB) technique in order to obtain organized magnetic films formed by monolayers of these clusters. Two strategies have been used with this aim. The first one consists of mixing Mn 12 acetate or benzoate derivatives with an amphiphile, while the second procedure is based on the use of Mn 12 derivatives specifically designed to form LB films. An alternative method is that of p…
Ambliopijas gadījumu analīze BKUS Acu slimību klīnikā
2021
Darbs ir uzrakstīts latviešu valodā uz 39 lapaspusēm. Tas satur 9 attēlus, 4 tabulas, 1 pielikumu un 42 atsauces uz literatūras avotiem. Mērķis bija apkopot datus par ambliopijas dažādo tipu izplatību Latvijas Acu slimību klīnikā. Darbā tika analizētas 1216 pacientu ambulatorās kartes no Bērnu klīniskās universitātes slimnīcas Acu slimību klīnikas. Pētījumā pielietotas teorētiskās un empīriskās metodes. Dažādu refrakciju sadalījums ir atkarīgs no ambliopijas tipa un pakāpes. Ambliopijas izplatība klīniskās oftalmoloģijas populācijā ir 12,3 %. Dominējošie ambliopijas veidi ir refraktīvā un šķielēšanas ambliopijas. Vidējais vecums, kad ambliopija tiek diagnosticēta ir 5 ± 3,2 gadi. Pacientiem…
Cribado de alteraciones visuales (parte 2)
2015
En el presente trabajo se revisan y actualizan las recomendaciones de PrevInfad sobre el cribado de alteraciones visuales en la infancia. Se analizan los beneficios en salud de la deteccion precoz, la validez y seguridad de las pruebas de cribado, la efectividad del tratamiento y los posibles riesgos de la deteccion precoz y el tratamiento de los problemas detectados. PrevInfad recomienda incluir la inspeccion ocular y la prueba del reflejo rojo en las visitas de salud de los primeros seis meses de vida, asi como la deteccion de alteraciones visuales (ambliopia, estrabismo y errores de refraccion) a la edad de 3-5 anos. La evidencia para evaluar el balance entre los beneficios y los riesgos…

On Combinatorial Generation of Prefix Normal Words
2014
A prefix normal word is a binary word with the property that no substring has more 1s than the prefix of the same length. This class of words is important in the context of binary jumbled pattern matching. In this paper we present an efficient algorithm for exhaustively listing the prefix normal words with a fixed length. The algorithm is based on the fact that the language of prefix normal words is a bubble language, a class of binary languages with the property that, for any word w in the language, exchanging the first occurrence of 01 by 10 in w results in another word in the language. We prove that each prefix normal word is produced in O(n) amortized time, and conjecture, based on expe…
How self-assembly of amphiphilic molecules can generate complexity in the nanoscale
2015
Abstract Given the importance of nanomaterials and nanostructures in modern technology, in the past decades much effort has been directed to set up efficient bottom up protocols for the piloted self-assembly of molecules. However, molecules are generally disinclined to adopt the desired structural organization because they behave according to their own specific intermolecular interactions. Thus, only some selected classes of chemical compounds are capable to lead to useful self-assembled structures. Amphiphiles, simultaneously possessing polar and apolar moieties within their molecular architecture, can give a wide scenario of possible intermolecular interactions: polar–polar, polar–apolar,…
Supramolecular Chemical Sensors Based on Pyrene Monomer-Excimer Dual Luminescence
2010
The past ten years have seen a spectacular development of chemical sensors based on the monomer-excimer dual luminescence of aromatic systems, such as pyrene. Either in the form of integrated or multicomponent molecular devices these chemosensors have been attracting a high interest above all because of their unique ratiometric properties. This review will focus on the latter systems, which can be classified into two classes: Firstly, the assembly of receptor-effector conjugates is triggerred by the analyte of interest. As a result, the sensor shows monomer to excimer fluorescence switching upon substrate binding. Secondly, the supramolecular assembly that constitutes the sensor is perturbe…
