Observational constraints on inhomogeneous cosmological models without dark energy
2011
It has been proposed that the observed dark energy can be explained away by the effect of large-scale nonlinear inhomogeneities. In the present paper we discuss how observations constrain cosmological models featuring large voids. We start by considering Copernican models, in which the observer is not occupying a special position and homogeneity is preserved on a very large scale. We show how these models, at least in their current realizations, are constrained to give small, but perhaps not negligible in certain contexts, corrections to the cosmological observables. We then examine non-Copernican models, in which the observer is close to the center of a very large void. These models can gi…
Evaluation of the variations in chemical and microbiological properties of the sourdoughs produced with selected lactic acid bacteria strains during …
2022
This research aimed to analyze variations in chemical properties, microbiological characteristics and generated volatile organic compounds (VOCs) profile during sourdough fermentation. Sourdoughs were collected from different cities in Turkey at two different times and lactic acid bacteria (LAB) in the samples were identified with culture-independent and culture-dependent molecular methods. According to culture-dependent methodology, thirteen LAB species were identified. Lactobacillus spp. were identified as the major group according to MiSeq Illumina analysis. Technological potential of commonly isolated LAB species was evaluated. Due to high frequency of isolation, Fructilactobacillus san…

The waiting time for prostate cancer treatment in Italy: analysis from the PROS-IT CNR Study.
2022
Background Prostate cancer (PCa) is the second most common neoplasm in male patients. To date, there's no certain indication about the maximum waiting time (WT) acceptable for treatment beginning and the impact on oncological and functional outcomes has not been well established. Methods Data from the National Research Council PCa monitoring multicenter project in Italy (Pros-IT CNR) were prospectively collected and analyzed. WT was defined as the time from the bioptical diagnosis of PCa to the first treatment received. Patients were divided in two groups, using a time frame of 90 days. Quality of life was measured through the Italian version of the University of California Los Angeles-Pros…
Obtaining and Characterisation of Starch-Based Edible Films Incorporating Honey, Propolis and Bee Bread
2019
Abstract This research investigates the physical-chemical, sensorial and mechanical characteristics of starch-based edible films incorporating three types of bee hive products: honey, propolis and bee bread, in concentrations varying from 1% to 3%, reported to starch. The results indicates an increasing of films moisture, water activity, ash content and acidity, in the order: honey<propolis<bee bread, all values increasing with the increasing of hive products percentage into the control film; aw is remaining at very low values, under 0.4. Sensorial analysis indicated honey as the better suited for improving taste and flavour and bee bread for increasing colour intensity of the films; …
Influència de la curvatura del conducte radicular i del moviment en la fatiga cíclica dels instruments de sistemes de llima única
2015
L’objectiu de l’estudi ha sigut avaluar la resistència a la fatiga cíclica de quatres sistemes de llima única en conductes corbats, estudiar la influència del moviment i de l’àrea de la secció transversal. Metodologia. S’utilitzaren un total de 240 llimes noves de 4 sistemes de llima única amb un diàmetre a la punta de 0,25mm: 60 llimes WaveOne Primary (Densply-Maillefer), 60 llimes Reciproc R25 (VDW), 60 llimes OneShape (Micro-Mega) i 60 llimes F360 #25 (Komet Brasseler); que foren dividides de manera aleatòria en 24 grups (ni=10). Prèviament a l’estudi tots els instruments van ser inspeccionats amb un lupa estereomicroscòpica de 16 augments, per a anàlisi morfològic i per descartar qualse…
Edutec : revista electrónica de tecnología educativa
2015
Título, resumen y palabras clave en español y en inglés Resumen basado en el de la publicación Tras la primera formulación en 1995 sobre qué es una Webquest, ¿cuál es el estado de su desarrollo en el campo de la educación? Esta pregunta exige muchas miradas y respuestas. Se pone en evidencia el desarrollo de la producción científica sobre Webquest en las dos principales bases de datos científicas: WOS (Web of Science) y Scopus desde su formulación hasta la actualidad (1995-2014). El método es el análisis bibliométrico en base a las siguientes variables: número de artículos publicados, número de citas recibidas, principales revistas citantes, promedio de citas por año, nombre y país de los a…
Temas e interpretaciones del derecho sucesorio italiano
2021
El articulo quiere mostrar que las interpretaciones de las instituciones del derecho de sucesiones que consideran el interés familiar, como expresión del principio de solidaridad (cada vez más en una protección patrimonialista de la legitimidad), siempre prevalente sobre todos los demás intereses, ya no pueden ser compartidas, porque la solidaridad no se distingue del personalismo. Modernizar el derecho de sucesiones no significa tener que abdicar en favor del contrato, sino descubrir el valor de la autonomía privada y el potencial del acto de última voluntad. Es la centralidad de la persona humana y no sólo el principio de solidaridad (más aún si se entiende en un sentido patrimonialista) …
Content Variation of Iron and Copper in Wine Obtained from Wine Vineyards Recas
2013
Abstract Wine grapes are brought to the center in baskets, plastic containers, wooden bene, or more modern like metal bene. From picking and transport can be transmitted to grapes, the iron or copper from all equipment on metal and after will be transmitted also to wines produced. It must therefore control of how was made the insulation of protective metal bene to avoid contact the metal with grapes. The aim of this work involves evaluating the content of iron and copper in wines and vineyards of Recas. The results indicated that the values determined by methods Photocolorimeters were within normal limits and revealed that the level of iron and copper in samples analyzed were not influenced…
