Sesgo y encuadre en las noticias de TV : mecanismos de manipulación periodística a propósito del urbanismo y del agua en los informativos de Canal 9

2008

La Tesis verifica los mecanismos de manipulación periodística puestos en juego en los informativos de la cadena de televisión pública regional Canal 9, en el tratamiento de dos temas de actualidad, el urbanismo y el agua, que fueron significativos políticamente en el ámbito valenciano durante los meses anteriores a las elecciones autonómicas de 2007. La pretensión del estudio fue considerar desde la perspectiva académica, la controvertida manipulación repetidamente denunciada por profesionales, ciudadanos y partidos políticos por afectar a un medio de comunicación público, obligado por Ley a proporcionar información plural e independiente. En el marco teórico se adopta la noción de sesgo qu…

Molecular Determinants of the Response of Tumor Cells to Boswellic Acids

2011

Frankincense (Boswellia serrata, B. carterii) is used as traditional remedy to treat inflammatory diseases. The molecular effects of the active ingredients, the boswellic acids, on the immune system have previously been studied and verified in several clinical studies. Boswellic acids also inhibit cancer cell growth in vitro and in vivo. The molecular basis of the cytotoxicity of boswellic acids is, however, not fully understood as yet. By mRNA-based microarray, COMPARE, and hierarchical cluster analyses, we identified a panel of genes from diverse functional groups, which were significantly associated with sensitivity or resistance of a- or b-boswellic acids, such as transcription factors,…

The Internuclear Ophthalmoplegias

1993

Internuclear ophthalmoplegia (INO), which is caused by an ipsilateral medial longitudinal fasciculus (MLF) lesion, is characterized by adduction paresis of lateral gaze, usually with spared convergence [1–4]. In the opposite eye, abduction nystagmus and hypermetric abduction saccades are the main clinical and electro-oculographic abnormalities [1, 5, 6]. The origin of both is still debated. Abduction nystagmus has been explained by (a) an additional horizontal gaze paresis [7]; (b) vergence mechanisms aimed at alignment of the visual axes [8]; (c) interruption of descending excitatory projections from oculomotor nucleus internuclear neurons to contralateral abducens nucleus motoneurons [9];…

Potential Impact of Global Climate Change on Species Richness of Long-Distance Migrants

2003

Little evidence exists demonstrating that global climate change leads to systematic changes in the struc- ture of ecological communities. For avian communities, one would expect warmer winters to lead to declines in numbers of long-distance migrants if resident birds benefit from warmer winters and impose increasing competi- tive pressure on migrants. To study the potential influence of global climate change on long-distance migrants, we correlated the number of all species of land birds and the number and proportion of long-distance migrants, short- distance migrants, and residents in 595 grid cells across Europe. We used mean temperature of the coldest month, mean spring temperature, and …

Reconstrucció del paisatge rural i urbà d'Almenara i La Llosa entre els segle XIII al XVI

2023

La tesi titulada «Reconstrucció del paisatge rural i urbà d'Almenara i La Llosa entre els segles XIII-XVI», aprofundeix en l'evolució del paisatge cultural d'ambdós municipis i l'estudi de la seua població. Amb la finalitat de valorar els béns culturals municipals d'aquest període i destacar-ne la rellevància i les funcions en el passat. Cosa que possibilita una millor acceptació en el manteniment i en el respecte d'aquests béns en la societat actual. El paisatge constitueix una realitat dinàmica, ja que és resultat de processos ambientals, socials i culturals que s'han succeït al llarg del temps en el territori. Aquests processos estan marcats per les maneres de vida, les polítiques, les a…

Typology and Representation of Alterations in Territorial Units: A Proposal

2018

Abstract This article proposes a typology of boundary changes in territorial units at two points in time. The different types of changes are organized in a hierarchy and represented homogeneously, independently of the number of territorial units involved and of the changes to them. Each alteration is described precisely and unambiguously, and it is codified to allow the information to be treated automatically. In addition to providing efficient storage of the information about these changes, a canonical representation facilitates the automatic detection of inconsistencies in the database. At the same time, the typology allows us to define backward and forward equivalence rules, which helps …

Amber Particles as Living Plant Cell Markers in Flow Cytometry / Dzintara Daļiņas Kā Dzīvu Augu Šūnu Marķieri Plūsmas Citometrijā

2015

Abstract The unique biological properties of amber are well known. Amber particles that penetrate into the cellular matrix can potentially be used as markers of plant cell biological activity by identification of living cells in flow cytometry. However, there have been no studies on effect of amber particles on plant cells. The aim of this study was to determine effect of amber nano- and micro- (5 nm-3 μm) particles on somatic and gametic cells and to assess the possibility to use amber particles as alive plant cells markers. To reach the aim, fluorescence of cells was determined in the presence of amber particles, and amber components - spirit of amber and sodium succinate dibasic hexahydr…

The closer¿ the unsafer: may the lack of safe distance be a silent contributor to the burden of traffic crashes in Spain?

2020

Not keeping an adequate safe distance is one of the elements that are directly related to traffic accidents. The main objective of this research was to identify the aspects that modulate the safe distance-accidents relation. Specifically, the frequency and reasons why drivers do not keep the safe distance, the perception of drivers regarding the probability of penalty, the penalties imposed and their severity, and the drivers’ opinion on the effectiveness of such penalties in order to change this behavior. A questionnaire was administrated to a sample of 1,100 Spanish drivers having any kind of driving license. The results showed that only the 5,6% of drivers always or sometimes do not keep…

Variation in the TonB-dependent outer-membrane proteins in plant-associated strains of Pseudomonas fluorescens

2011

International audience; Genomic sequences of ten strains of plant-associated Pseudomonas spp. were surveyed for the presence of TonB-dependent outer-membrane proteins (TBDPs), which function in the uptake of substrates from the environment by many Gram-negative bacteria. The ten strains represent P. fluorescens, P. chlororaphis, and P. synxantha isolated from the phyllosphere, rhizosphere or soil. 14 to 45 TBDPs were identified in each strain, and phylogenetic analysis of the TBDPs identified five that are conserved across all ten genomes. Comparisons to proteins with known functions allowed the assignment of putative roles in uptake of heme, vitamin B12, copper, and the siderophore ferrich…
