Improved Solid Phase Extraction Procedure for Assay of Cephalosporins in Human Urine Samples

1998

Abstract Solid phase extraction technique has been evaluated for the treatment of urine samples in the analysis of cephalosporins before injection into an HP-Hypersil ODS-C18 column. Cephalexin, cefotaxime, cefazolin, cefuroxime, and cefoxitin were tested with seven different reversed-phase extraction column cartridges and the obtained urine extracts were not clean. However, 3M Empore extraction disk cartridges packed with octadecyl (C18) bonded silica provided clean extracts with a single extraction. The recoveries of the five cephalosporins ranged from 56 to 60 % in the 1.25–500 g/mL concentration range. The assay was accurate, precise, and adequate for testing the drug content in urine s…

Highly irregular graphs with extreme numbers of edges

1997

Abstract A simple connected graph is highly irregular if each of its vertices is adjacent only to vertices with distinct degrees. In this paper we find: (1) the greatest number of edges of a highly irregular graph with n vertices, where n is an odd integer (for n even this number is given in [1]), (2) the smallest number of edges of a highly irregular graph of given order.

Síndrome de Horner como manifestación de disección carotídea

2011

Caso Clínico: Un varón de 42 años se presenta con ptosis y miosis izquierda después de una historia de cefalea homolateral de 20 días de evolución, que empeora progresivamente durante los últimos días. Una angioresonancia revela disección de la arteria carótida interna. Discusión: El «síndrome de Horner doloroso» destaca como una urgencia médica por posible manifestación de una disección carotídea. Consideramos que el perfecto conocimiento de las urgencias neurooftalmológicas es de gran necesidad para el médico oftalmólogo y que estas requieren una atención multidisciplinaria para asegurar un seguimiento y tratamiento adecuado. Clinical Case: A 42-year-old man presented with ptosis and mios…

Iconografia e rappresentazione digitale

2017

Questo studio riguarda una ricerca svolta a partire dal 2016 sul tema della valorizzazione della rappresentazione architettonica attraverso una metodologia di lettura del patrimonio che ha messo in evidenza le possibilità offerte dalla modellazione digitale nell'interpretazione dell’iconografia storica, con l’obiettivo di acquisire una maggiore consapevolezza del territorio e del fatto architettonico. Nello specifico la ricerca ha riguardato lo studio dell’iconografia relativa alle cattedrali di Palermo, Monreale e Cefalù che rientrano nell'itinerario Arabo-Normanno dichiarato dall'UNESCO “Patrimonio Mondiale dell’Umanità”. Verrà qui trattato il caso studio di Cefalù con l’obiettivo di most…

Algoritmo diagnóstico para la toma de decisiones quirúrgicas en cirugía ortognática

2019

El deseo de alcanzar la belleza es universal. En todas las culturas y épocas el ser humano ha buscado plasmar la belleza en sus obras de arte. En la actualidad los cirujanos la buscan a través de la cirugía. El estudio de la bibliografía referida a la cirugía ortognática y los análisis cefalométricos vigentes muestran, como objetivo principal, restablecer el equilibrio oclusal y solo en segundo plano estudian la repercusión estética de la intervención. Esta tesis nace de la necesidad de dar respuesta a la pregunta: ¿Existe un modelo de estética aceptado universalmente en la sociedad española? (en la tesis solo se estudia a la población española de origen caucásico) y en el caso en que la re…

Nomination for inscription on the World Heritage List Unesco. Arab-Norman Palermo and cathedral churches of Cefalù and Monreale

2012

Il dossier di candidatura per l'iscrizione nella WHL rappresentano l’insieme degli edifici costituenti l’itinerario arabo normanno rappresentano un eccezionale valore universale come esempio di convivenza e interazione tra diverse componenti culturali di provenienza storica e geografica eterogenea (sincretismo culturale). Tale fenomeno ha generato uno stile architettonico originale in cui sono mirabilmente fusi elementi bizantini, islamici e romanici, capace di volta in volta di prodursi in combinazioni uniche, di eccelso valore artistico e straordinariamente unitarie

The democratization process: An empirical appraisal of the role of political protest

2020

Abstract This paper analyses the role of peaceful and violent protest in the democratization process. We interpret the democratization process as a sequence of phases so as to allow citizens' and elites' preferences for democracy to vary according to the particular phase that a country is experiencing. By doing so we jointly model the probability of protest and of moving through different phases of democracy taking into account time-constant and time-varying unobserved heterogeneity. In particular, we develop a multivariate finite mixture model that introduces a latent variable to capture unobservable factors. On a sample of 171 countries from 1971 to 2010, we provide evidence that protest …

Real-Time Localization of Epileptogenic Foci EEG Signals: An FPGA-Based Implementation

2020

The epileptogenic focus is a brain area that may be surgically removed to control of epileptic seizures. Locating it is an essential and crucial step prior to the surgical treatment. However, given the difficulty of determining the localization of this brain region responsible of the initial seizure discharge, many works have proposed machine learning methods for the automatic classification of focal and non-focal electroencephalographic (EEG) signals. These works use automatic classification as an analysis tool for helping neurosurgeons to identify focal areas off-line, out of surgery, during the processing of the huge amount of information collected during several days of patient monitori…
