Viscous Synergism in Carrageenans (κ and λ) and Locust Bean Gum Mixtures: Influence of Adding Sodium Carboxymethylcellulose
2001
Se han estudiado las interacciones sinergicas entre la goma de garrofin (LBG) y dos tipos de carragenanos (kappa y lambda). Para cada mezcla se obtuvo el indice de sinergia viscosa, Iy, en funcion de la relacion de concentraciones, z =c'LBG/c'car, y de la velocidad de cizalla. Los valores de estos indices disminuyeron al aumentar la velocidad de cizalla en ambos sistemas binarios. En las mezclas de LBG + K, I, presento un maximo para una relacion de concentraciones z = 60/40, que puede considerarse como la optima proporcion de estas gomas en la mezcla. Sin embargo, en los sistemas LBG + A, I, aumento con z en todo el intervalo considerado, es decir, la mayor sinergia correspondio a las meno…
LA DOPPIA CITAZIONE DEL FR. 964 DI EURIPIDE NEL DE INDOLENTIA DI GALENO
2013
The purpose of this study is to demonstrate that the second quotation of the Euripidean fr. 964 N 2 in the De indolentia, a Galenic treatise recently saved from oblivion thanks to Antoine Pietrobelli, is in fact an interpolation due to the enterprise of a scribe. The argumentation is based on words coming immediately before and after the presumed quotation.
Fixed point results for $GP_(Λ,Θ)$-contractive mappings
2014
In this paper, we introduce new notions of GP-metric space and $GP_(Λ,Θ)$-contractive mapping and then prove some fixed point theorems for this class of mappings. Our results extend and generalized Banach contraction principle to GP-metric spaces. An example shows the usefulness of our results.
Etude des effets cohérents dans la vapeur de rubidium atomique sous irradiation laser bi-chromatique
2013
The effect of electromagnetically induced transparency is observed, using nanocelland microcell. The EIT-resonance with good parameters (high contrast and small FWHM) is obtained in thick cells. The EIT-resonance splitting in magnetic field is observed for the cases of D1-line of 85Rb and 85Rb. The theoretical model, explaining the EIT-resonance components frequency shift dependence on magnetic field strength is presented. The theoretical and experimental results are compared and good agreement is shown. Also the EIT-resonance behavior in hyperfine Paschen-Back regime is presented and explained. For the first time the N-type resonance in microcell is observed. Good parameters of theN-type r…
Dynamics of gene regulatory networks and their dependence on network topology and quantitative parameters – the case of phage λ
2019
Background Gene regulatory networks can be modelled in various ways depending on the level of detail required and biological questions addressed. One of the earliest formalisms used for modeling is a Boolean network, although these models cannot describe most temporal aspects of a biological system. Differential equation models have also been used to model gene regulatory networks, but these frameworks tend to be too detailed for large models and many quantitative parameters might not be deducible in practice. Hybrid models bridge the gap between these two model classes – these are useful when concentration changes are important while the information about precise concentrations and binding…
Primary Plasma Cell Leukemia Associated with Adult Fanconi Syndrome
2006
Abstract Primary plasma cell leukemia (PCL) is a rare variant of multiple myeloma that occurs de novo in patients without a history of plasma cell disorder. We describe a case of λ PCL that showed a prolonged survival of 2 years and 6 months associated with a generalized dysfunction of the proximal renal tubule. On presentation, the patient had anemia (hemoglobin level, 11 g/dL), thrombocytopenia (platelet count, 102,000/μL), and renal insufficiency (creatinine level, 2.75 mg/dL; creatinine clearance, 19 mL per minute; urea, 71 mg/dL). In addition to the common clinical picture, our case showed proteinuria (30 mg/dL), glycosuria (150 mg/dL) with normal glycemia, low uric acid concentration …

Recent results on mesonic weak decay of Λ-hypernuclei
2010
The FINUDA experiment has performed a systematic study of mesonic weak decay of p-shell Λ-hypernuclei. Recent results on the mesonic decay spectra and ratios are illustrated and discussed.
Document Word Clouds: Visualising Web Documents as Tag Clouds to Aid Users in Relevance Decisions
2009
Περιέχει το πλήρες κείμενο Information Retrieval systems spend a great effort on determining the significant terms in a document. When, instead, a user is looking at a document he cannot benefit from such information. He has to read the text to understand which words are important. In this paper we take a look at the idea of enhancing the perception of web documents with visualisation techniques borrowed from the tag clouds of Web 2.0. Highlighting the important words in a document by using a larger font size allows to get a quick impression of the relevant concepts in a text. As this process does not depend on a user query it can also be used for explorative search. A user study showed, th…
The prologue and the fi rst stasimon of Oedipus at Colonus: a comparative study
2017
En este trabajo proponemos un análisis del estásimo primero de la tragedia Edipo en Colono de Sófocles a partir de los versos 16 a 18 del prólogo de la misma obra. La comparación entre ambos pasajes puede ser importante en la medida en que el ἄλσος descrito en el prólogo es presentado como un espacio, dramáticamente importante, que se desarrolla poéticamente en el primer estásimo. Ambas descripciones presentan puntos en común que no sólo pueden ayudarnos a entender mejor la naturaleza de este bosque sagrado, sino también evidencian la programación dramática de los susodichos versos prologales. In this paper we analyze the fi rst stasimon of the tragedy Oedipus at Colonus of Sophocles based …
