Giant hepatocellular adenoma as cause of severe abdominal pain: a case report
2007
Abstract The authors describe the case of a large hepatocellular adenoma diagnosed in a 30-year old woman who came to us complaining of acute pain in the upper abdominal quadrants. The patient had been taking an oral contraceptive pill for the last ten years. We present the clinical features, the diagnostic work-up and the treatment prescribed.
Feasibility of using more polishable aggregates in dense-graded asphalt surface mixture: Case study of dolomite
2022
This study aimed to evaluate the feasibility of using more dolomite aggregates in asphalt surface mixtures that are typically used by West Virginia Division of Highways (WVDOH). The laboratory test results indicated that increasing dolomite content in asphalt surface mixtures resulted in a faster deterioration rate at the early polishing stage. In addition, asphalt surface mixtures containing more than 50% dolomite coarse aggregates would significantly reduce roadway safety. The field test results validated that dolomite shall not exceed 50% of coarse aggregate in asphalt surface mixture if the projected traffic volume is greater than 3.0 million equivalent single axle loads (ESALs).
From Laboratory Mixes Evaluation to Full Scale Test: Fatigue Behavior of Bio-Materials Recycled Asphalt Mixtures
2020
The present paper describes the full-scale accelerated test, carried out on asphalt pavements made up with bio-materials, especially designed to help reusing Reclaimed Asphalt (RA) by re-activating the aged binder. Four pavement sections were evaluated: three pavement sections with innovative bio-materials (bio-recycled asphalt mixtures), and a reference section with a conventional, high modulus asphalt mix (EME2). In this study, fatigue resistance was first evaluated in laboratory, with two-points bending test, and then at full scale under heavy traffic loading, with the IFSTTAR accelerated pavement testing facility. The evolution of bio-materials recycled asphalt mixture characteristics, …

Ruolo del Nucleo di Valutazione per l´attivazione delle procedure per la predisposizione dello schema di APQ per la logistica ed il trasporto merci i…
2006
Il presente contributo riferisce dell´esperienza del Nucleo della Sicilia —Area Valutazione progetti, in merito alla redazione della relazione tecnica di accompagnamento all´APQ per il Trasporto delle Merci e per la Logistica in Sicilia. Partendo dalle Disposizioni contenute nella delibera CIPE n.20/2004 e dalle indicazioni della nota di indirizzo Rete NUVV dic/2004 in proposito, il gruppo di lavoro ha proceduto alla necessaria acquisizione delle informazioni e dei dati relativi a ciascun singolo intervento previsto in APQ, ricostruendo i processi e le procedure, come pure la sequenza tecnico-procedurale con la quale si sono sviluppate le proposte (analisi del fabbisogno, individuazione deg…
Non-destructive automatic determination of aspect ratio and cross-sectional properties of fibres
2015
A novel method for computerised estimation of the aspect ratio distribution and various cross-sectional geometrical properties of fibres in short-fibre reinforced composites is proposed. The method, based on X-ray micro-computed tomography, is non-destructive and does not require user intervention. Based on results on specially fabricated model material, the accuracy and precision of the method seems adequate. The method is applied in analysing a manufacturing process of wood fibre reinforced thermoplastic composite. The results indicate a significant decrease of the aspect ratio of fibres during the processing steps. Finally, the feasibility of the method is assessed by estimating paramete…

Pulmonary actinomycosis. Fine needle aspiration diagnostic.
2011
Atículo publicado en: Invest Clin 52(4): 356 - 360, 2011 Se presentan 4 casos de actinomicosis pulmonar en pacientes mayores de 55 años, 2 de ellos con enfermedad pulmonar obstructiva crónica (EPOC), que mostraron un aumento de la tos productiva, episodios de disnea, hemoptisis y fiebre de larga evolución. En las radiografías de tórax de rutina se observaban imágenes segmentarias de consolidación aérea, sugestivas de cuadros neumónicos no resueltos o neoplasia. La tomografía axial computarizada (TAC) mostró hallazgos similares a los anteriores. Los cultivos de esputo y las pruebas de Mantoux fueron repetidamente negativos. Debido a la mala evolución de los pacientes y a los hallazgos radiol…
Rapid developmental switch in the mechanisms driving early cortical columnar networks
2006
The immature cerebral cortex self-organizes into local neuronal clusters long before it is activated by patterned sensory inputs. In the cortical anlage of newborn mammals, neurons coassemble through electrical or chemical synapses either spontaneously or by activation of transmitter-gated receptors. The neuronal network and the cellular mechanisms underlying this cortical self-organization process during early development are not completely understood. Here we show in an intact in vitro preparation of the immature mouse cerebral cortex that neurons are functionally coupled in local clusters by means of propagating network oscillations in the beta frequency range. In the newborn mouse, this…
Paisaje cultural y patrimonio litoral valenciano
2004
El patrimonio litoral no debe entenderse como un catálogo de elementos individuales. Las actividades humanas sobre el medio físico produjeron un paisaje que debe ser protegido en su integridad. Las relaciones espaciales, la observación de los factores físicos, las nociones de escala y relación son importantes. Este capítulo analiza las dificultades de una definición de patrimonio litoral, las características del paisaje cultural valenciano costero, y, en concreto, tres tipos de paisaje, donde se integran los elementos del patrimonio: el paisaje de la defensa (torres, castillos...), el paisaje de los núcleos habitados (ciudades y graus), el paisaje de la producción (puertos, pesca y otros ap…
