Carrera profesional del maestro de obras del rey en el Reino de Valencia en época de los en la época de los Austrias: la sucesión al cargo que ocupó …

2009

El maestro de obras reales en el Reino de Valencia se ocupó de la supervisión de los trabajos en los bienes inmuebles del patrimonio regio, que incluía arquitectura e ingeniería civil, militar e hidráulica. Presentamos el informe enviado por el virrey en 1622 sobre los tres candidatos al cargo: Antonio Picó, Jerónimo Negret y Francisco Arboreda (o Arboleda). Resulta especialmente interesante la información sobre este último, que lo ocupó hasta 1636, pues en la exposición de méritos, por un lado, ofrece información sobre las obras realizadas por sus ancestros, Joan Arboreda, que identificamos con el Joan Navarro que ocupó el mismo cargo en las décadas centrales del siglo XVI, y Jerónimo Arbo…

Los castillos valencianos en el siglo XIII. Del "hisn" musulmán al "castrum" cristiano

2004

Las fuentes escritas en su doble vertiente cronística y documental y el examen de os restos materiales, que sin necesidad de excavación previa aún se pueden contemplar, son nuestras bases de apoyo de este análisis. Ellas son las que, a su vez, delimitan la cronología y permiten que se centre de forma especial en época cristiana. El primer tipo de construcción castral estaba formada por tres partes: una primera la integraban una serie de construcciones ubicadas en su parte superior, que sólo en algunos casos podernos denominara alcazaba. A continuación hay que citar el albacar y, por último, una medina o ciudad de amplia superficie en su parte baja. El segundo grupo de castillos estaba integ…

Bond strength evaluation of the veneering-core ceramics bonds.

2009

The purpose of this study was to determine whether the bond of veneering porcelain to a ceramic core in bilayered ceramics was similar to that of the metal ceramic control of well known behaviour. Six groups of nine specimens each were fabricated, whose dimensions were 15 mm long and 8 mm in diameter at the core, and 2 mm long and 8 mm in diameter for the veneer. The groups were GR. 1 (control group): CrNi alloy/d.SIGN (Ivoclar), GR. 2: IPS e.maxPress/IPS e.maxCeram (Ivoclar), GR. 3: IPS e.maxZirCad/ IPS e.maxZirPress (Ivoclar), GR. 4: IPS e.maxZirCad/IPS e.maxCeram (Ivoclar), GR. 5: Lava Frame (3M ESPE)/ Lava Ceram (3M ESPE) and GR. 6: Lava Frame (3M ESPE)/IPS e.maxCeram (Ivoclar). A shear…

Study of the biochemical composition and physico-chemistry of a protein-based food model of Parkia biglobosa

2022

In West Africa, the seed of the cowpea (Parkia biglobosa) is used in traditional pharmacopoeia and especially in human food as a condiment. This legume is very rich in proteins and lipids and remains a poorly exploited source of protein. Our thesis focuses on the valorization of Néré seeds for the development of new protein-rich products of plant origin as an alternative to the use of soybean as a basic ingredient. The objectives were : (i)biochemical and physicochemical characterization of protein isolates from Néré seed flour according to the extraction process, (ii) selection of proteolytic lactic acid bacteria capable of fermenting Néré juice, reducing anti-nutritional factors in order …

Infecciones por clamidias

2007

Las clamidias son un grupo peculiar de bacterias, cuyo ciclo vital transcurre en parte en el interior de las células. Tienen la propiedad de adherirse a determinados epitelios, en los que pueden acabar produciendo infecciones. Existen tres especies patógenas para el hombre: Chlamydia trachomatis, que produce infecciones fundamentalmente en los epitelios genital y urinario, y C. psittaci y C. pneumoniae, que producen fundamentalmente infecciones respiratorias. A las dos últimas se les clasifica en la actualidad en un género diferente, el de las Chlamydophilas.

Modelo empírico para la determinación de clorofila-a en aguas continentales a partir de los futuros Sentinel-2 y 3. Validación con imágenes HICO

2014

[EN] Chlorophyll-a concentration is one of the main indicators of inland waters quality. Using CHRIS/PROBA images and in situ data obtained in four lakes in Colombia and Spain, we obtained empirical models for the estimation of chlorophyll-a concentration, which can be directly applied to future images of MSI Sentinel-2 and OLCI Sentinel-3 sensors. The models, based on spectral band indices, were validated with data from the hyperspectral sensor HICO, onboard of the International Space Station.

Partial vinylphenol reductase purification and characterization from Brettanomyces bruxellensis

2008

International audience; Brettanomyces is the major microbial cause for wine spoilage worldwide and causes significant economic losses. The reasons are the production of ethylphenols that lead to an unpleasant taint described as 'phenolic odour'. Despite its economic importance, Brettanomyces has remained poorly studied at the metabolic level. The origin of the ethylphenol results from the conversion of vinylphenols in ethylphenol by Brettanomyces hydroxycinnamate decarboxylase. However, no information is available on the vinylphenol reductase responsible for the conversion of vinylphenols in ethylphenols. In this study, a vinylphenol reductase was partially purified from Brettanomyces bruxe…

Two heterologously expressed Planobispora rosea proteins cooperatively induce Streptomyces lividans thiostrepton uptake and storage from the extracel…

2010

Abstract Background A bacterial artificial chromosomal library of Planobispora rosea, a genetically intractable actinomycete strain, was constructed using Escherichia coli-Streptomyces artificial chromosome (ESAC) and screened for the presence of genes known to be involved in the biosynthesis of antibiotics. Results One clone with a 40 kb insert showed antimicrobial activity against Gram positive bacteria. Insert sequence analysis and subcloning experiments revealed that the bioactivity was due to a 3.5 kb DNA fragment containing two open reading frames. These orfs encode two proteins with high similarity to a putative membrane protein of Streptomyces coelicolor and to the nogalamycin resis…
