Composition and seasonal changes in filamentous algae in floating mats
Authors: Pikosz Marta , Messyasz Beata
Published: June 2015

The occurrence of algal-cyanobacterial metaphyton mats in field (Konojad village) and artificial ponds (Poznań city) was investigated in the Wielkopolska region. The surface area of algal mats ranged between ca. 45% (natural pond) and 10% (artificial pond) of the total water surface, and the mats occurred from the water surface to the bottom; the algal diversity was similar in both types of ponds, i.e. about 10 taxa. The most frequently recorded and dominant taxa in small water bodies were: Spirogyra spp., Cladophora fracta in the artificial pond and Oedogonium spp., Cladophora rivularis in the natural pond. The dynamics of macroalgae demonstrated a pattern comprising different phases of taxa dominance. For example, April regarded as the first phase was characterized by a small amount of metaphyton, represented by Tribonema and Ulothrix taxa. In May, these species disappeared and were replaced by: Oedogonium spp. and Cladophora spp. which formed large aggregations in the field pond, and Spirogyra spp. which abundantly proliferated in the artificial pond. From June, however, Oedogonium and/or Cladophora significantly dominated in the mat structure and at the same time covered a large area of the water surface. The algal community was dominated by common algal taxa, among which single filaments of other taxa could also occur.
Characterization of a mineral coating of the plant Dyerophytum indicum
Authors: Chernyshev Anatoly , Melghit Khaled
Published: June 2015

The mineral coating of Dyerophytum indicum Kuntze (Plumbaginaceae) was analyzed by isotope ratio mass spectrometry, X-ray diffraction, thermogravimetric and differential thermal analysis, and scanning electron microscopy/energy-dispersive X-ray spectroscopy methods. Its composition was found to be similar to those of the carbonate mixtures isolated from rotting cacti and speleothems. The coating consisted of three major phases (monohydrocalcite, nesquehonite, and calcite), a minor phase of hydromagnesite, and traces of silica and sylvite. This is the first time that the occurrence of monohydrocalcite, nesquehonite, and hydromagnesite in a living higher plant has been reported. A possible mechanism of the formation of the coating is also discussed.
The Exegetical Motet
Authors: Crook David
Published: June 2015

What made a motet appropriate for performance on a particular occasion in the sixteenth century? Previous studies have demonstrated that motets performed on a given day generally drew their texts from the liturgy of that day. Yet many of the eighty-five motets assigned to the Sundays and major feasts of the year in Johannes Rühling's Tabulaturbuch (1583) do not. What mattered to this Lutheran organist was not a motet text's previous liturgical association but its ability to gloss—sometimes in surprising ways—the Gospel or Epistle lesson of the day. His approach has strong parallels in a tradition of Lutheran preaching grounded in exegesis of the assigned lessons. The same exegetical approach figures, moreover, in Catholic use of the motet, exemplified both in musical sources, such as Andreas Pevernage's Cantiones sacrae (1578 and 1602), and in performances recorded in the diaries of the Sistine Chapel.
Opéra-comique on the Eve of Revolution: Dalayrac's Sargines and the Development of “Heroic” Comedy
Authors: Doe Julia
Published: June 2015

This article draws upon archival evidence to trace the development of opéra-comique—and its broader political import—in the final years of the ancien régime. It focuses in particular on the opening of the Salle Favart, the first new and custom-built theater for the Comédie-Italienne, in 1783. This change in venue attracted elite crowds to France's second lyric stage, solidifying a prominent rift between the generic status of opéra-comique and the social status of its audiences. The patronage of wealthy Parisians, in turn, enabled the company to augment its staging resources and present works on an increasingly expansive scale. On the eve of the Revolution, the theater's programming committee supported the production of operas on heroic, historical subjects. Not only did such patriotic tales inspire fantastical scenery and effects, but they also enhanced the prestige of opéra-comique, which came to challenge its tragic counterpart as a legitimate, and legitimately national, lyric form. An examination of Sargines (1788), by Nicolas-Marie Dalayrac and Jacques-Marie Boutet (known as Monvel), demonstrates how such “heroic” works played into disputes over the traditional limitations of the genre. It also underscores how the aesthetic we now associate with the turbulent 1790s was, in many cases, created out of materials developed in the previous decade, shedding light on the complex relationship between ancien-régime culture and revolutionary art.
Rapid progression of Staphylococcus lugdunensis mechanical prosthetic valve endocarditis
Authors: Naji Darwish I. , Pak Alexander , Lawless Jamie , Main Michael L.
Published: June 2015

A 66-year-old woman with a remote history of mitral valve replacement (mechanical bileaflet valve) due to rheumatic heart disease presented with symptoms consistent with infectious endocarditis. Subsequent blood cultures grew Staphylococcus lugdunensis. A transesophageal echocardiogram demonstrated large vegetations on the atrial aspect of the mitral valve, with a Doppler derived mean pressure gradient of 13 mmHg (Fig. 1 and Video 1). Appropriate i.v. antibiotics were initiated and a surgical consultation was obtained. A second transesophageal echocardiogram was performed 6 days later after she developed acute respiratory failure secondary to pulmonary edema, requiring mechanical ventilation (Video 2). This examination revealed a significant increase in size of the mitral vegetations, with the largest measuring 2.2 cm in maximum dimension, with new complete obstruction of one mechanical leaflet, and with dense spontaneous echo contrast secondary to prosthetic mitral valve obstruction. She subsequently underwent urgent open heart surgery and redo mitral valve replacement with a bioprosthetic valve. Valve obstruction due to large vegetations occurs rarely with infectious endocarditis and is more common with prosthetic (in comparison with native) valves (1, 2, 3). Serial transesophageal echocardiography imaging was helpful in diagnosing this life-threatening complication
Nested Levels of Adaptive Divergence: The Genetic Basis of Craniofacial Divergence and Ecological Sexual Dimorphism
Authors: Parsons Kevin J , Wang Jason , Anderson Graeme , Albertson R Craig
Published: June 2015

Exemplary systems for adaptive divergence are often characterized by their large degrees of phenotypic variation. This variation represents the outcome of generations of diversifying selection. However, adaptive radiations can also contain a hierarchy of differentiation nested within them where species display only subtle phenotypic differences that still have substantial effects on ecology, function, and ultimately fitness. Sexual dimorphisms are also common in species displaying adaptive divergence and can be the result of differential selection between sexes that produce ecological differences between sexes. Understanding the genetic basis of subtle variation (between certain species or sexes) is therefore important for understanding the process of adaptive divergence. Using cichlids from the dramatic adaptive radiation of Lake Malawi, we focus on understanding the genetic basis of two aspects of relatively subtle phenotypic variation. This included a morphometric comparison of the patterns of craniofacial divergence between two ecologically similar species in relation to the larger adaptive radiation of Malawi, and male–female morphological divergence between their F2 hybrids. We then genetically map craniofacial traits within the context of sex and locate several regions of the genome that contribute to variation in craniofacial shape that is relevant to sexual dimorphism within species and subtle divergence between closely related species, and possibly to craniofacial divergence in the Malawi radiation as a whole. To enhance our search for candidate genes we take advantage of population genomic data and a genetic map that is anchored to the cichlid genome to determine which genes within our QTL regions are associated with SNPs that are alternatively fixed between species. This study provides a holistic understanding of the genetic underpinnings of adaptive divergence in craniofacial shape.
Using Bayesian Multilevel Whole Genome Regression Models for Partial Pooling of Training Sets in Genomic Prediction
Authors: Technow Frank , Totir L Radu
Published: June 2015

Training set size is an important determinant of genomic prediction accuracy. Plant breeding programs are characterized by a high degree of structuring, particularly into populations. This hampers the establishment of large training sets for each population. Pooling populations increases training set size but ignores unique genetic characteristics of each. A possible solution is partial pooling with multilevel models, which allows estimating population-specific marker effects while still leveraging information across populations. We developed a Bayesian multilevel whole-genome regression model and compared its performance with that of the popular BayesA model applied to each population separately (no pooling) and to the joined data set (complete pooling). As an example, we analyzed a wide array of traits from the nested association mapping maize population. There we show that for small population sizes (e.g., <50), partial pooling increased prediction accuracy over no or complete pooling for populations represented in the training set. No pooling was superior; however, when populations were large. In another example data set of interconnected biparental maize populations either partial or complete pooling was superior, depending on the trait. A simulation showed that no pooling is superior when differences in genetic effects among populations are large and partial pooling when they are intermediate. With small differences, partial and complete pooling achieved equally high accuracy. For prediction of new populations, partial and complete pooling had very similar accuracy in all cases. We conclude that partial pooling with multilevel models can maximize the potential of pooling by making optimal use of information in pooled training sets.
Reconstruction of Genome Ancestry Blocks in Multiparental Populations
Authors: Zheng Chaozhi , Boer Martin P , van Eeuwijk Fred A
Published: June 2015

We present a general hidden Markov model framework called reconstructing ancestry blocks bit by bit (RABBIT) for reconstructing genome ancestry blocks from single-nucleotide polymorphism (SNP) array data, a required step for quantitative trait locus (QTL) mapping. The framework can be applied to a wide range of mapping populations such as the Arabidopsis multiparent advanced generation intercross (MAGIC), the mouse Collaborative Cross (CC), and the diversity outcross (DO) for both autosomes and X chromosomes if they exist. The model underlying RABBIT accounts for the joint pattern of recombination breakpoints between two homologous chromosomes and missing data and allelic typing errors in the genotype data of both sampled individuals and founders. Studies on simulated data of the MAGIC and the CC and real data of the MAGIC, the DO, and the CC demonstrate that RABBIT is more robust and accurate in reconstructing recombination bin maps than some commonly used methods.
EU merger review of the acquisition of non-controlling minority shareholdings: where to now?
Authors: Montag Frank , Wilks Mary
Published: June 2015

On 9 July 2014, the European Commission (the Commission) published its White Paper “Towards more effective EU merger control”, which reviewed the operation of the EU Merger Regulation (EUMR) ten years after the introduction of the substantive test of “significant impediment to substantial competition” (SIEC) and proposed certain specific improvements, including the review of non-controlling minority interests under the EUMR. The 2014 White Paper followed approximately one year of consultation with Member States and interested parties, and was accompanied by a Staff Working Document, which analyses in more detail the considerations underlying the policy proposals in the 2014 White Paper, and an Impact Assessment, which analyses the potential benefits and costs of the various policy options considered.

Less than six months after the consultation on the 2014 White Paper closed, Competition Commissioner Margrethe Vestager indicated that the Commission is reconsidering its proposals to allow it to review the acquisition of non-controlling minority shareholdings under the EUMR. This decision has been welcomed by many in the business and legal community as the “targeted transparency system” proposed by the Commission had raised a number of concerns regarding proportionality, legal certainty, cost and administrative burden.

Whilst we await the Commission’s next move, this article considers whether non-controlling minority shareholdings should be subject to EU merger control and the extent to which the Commission’s originally envisaged system adequately dealt with the issues it sought to address. This article also proposes a number of principles that the authors suggest should be taken into account when designing a balanced system of merger review for acquisitions of non-controlling minority shareholdings in which the burden of the additional review is proportionate to the goals pursued.
Zusammenschlüsse „unter dem Radar“: Zur Verfolgungsverjährung bei Verstößen gegen das Vollzugsverbot der deutschen Fusionskontrolle
Authors: von Schreitter Florian
Published: June 2015

Verstöße gegen das Vollzugsverbot der deutschen Fusionskontrolle ziehen – ebenso wie Kartellverstöße oder andere Wettbewerbsbeschränkungen – ordnungswidrigkeitenrechtliche Folgen nach sich. Aus Unternehmenssicht birgt dieser Umstand nicht nur aufgrund der finanziellen Folgen der Sanktionierung, sondern insbesondere aufgrund der „Langlebigkeit“ der entsprechenden staatlichen Eingriffsmöglichkeit. Denn nach derzeit vorherrschender Auffassung ist der Verstoß gegen das Vollzugsverbot ein Dauerdelikt. Der vorliegende Beitrag stellt sich dieser bislang kaum diskutierten Auffassung entgegen.
Educational policies and activities for preschool children: Reflections from the cultural-historical approach and activity theory
Authors: González Moreno Claudia Ximena , Solovieva Yulia , Quintanar Rojas Luis
Published: June 2015

Educational activities employed with preschool children
have significance in their development and preparation for
school learning. For this reason, it is necessary to analyze
the relationship established between educational policies
and educational activities for the preschool population in the
Colombian context. In this paper, these two aspects interact to
contribute to its conclusion. The teacher’s task is to promote
the integral development of children and ensure an optimal
level of preparation for schooling. Considering current
pedagogical practice, this task is not successfully carried out
as required by the objectives of educational policy. However,
monitoring this psychological and pedagogical approach
based on cultural-historical theory highlights both theoretical
foundations and methodological pathways for innovating with
regard to the educational status of preschool.
Evaluation of the diagnostic performance of platelet-derived indices for the differential diagnosis of thrombocytopenia in pediatrics
Authors: Aponte Barrios Nelson Hernando , Linares Ballesteros Adriana , Sarmiento Urbina Isabel Cristina , Uribe Botero Gloria Inés
Published: June 2015

Background. Platelet-derived indices have a well-established correlation with the differential diagnosis of thrombocytopenia in adult-based research. These indices include mean platelet volume, platelet distribution width, and platelet-large cell ratio.

Objective. To determine the values of platelet-derived indices in a pediatric population with diagnoses of thrombocytopenia and their etiologic correlation.

Materials and methods. Analytic observational diagnostictest study. The population for this analytical study was pediatric patients between 6 months and 18 years of age who had thrombocytopenia (<100x109/L). The study period was 18 months long.

Results. Of 54 subjects, 18 (33.3%) were diagnosed with idiopathic thrombocytopenic purpura, and 36 (66.7%) were diagnosed with acute leukemia. Mean age was 7.4 years and 6.8 years for immune thrombocytopenic purpura and acute leukemia, respectively. Mean platelet distribution width values for immune thrombocytopenic purpura and acute leukemia were 15.08 fL and 10.73, respectively. Mean MPV for immune thrombocytopenic purpura and acute leukemia was 11.7 fL and 9.8 fL, respectively. Mean platelet-large cell ratio was 38.26% and 24.97% for idiopathic thrombocytopenic purpura and acute leukemia, respectively. Differences in these three distinct platelet indices between idiopathic thrombocytopenic purpura and acute leukemia were statistically significant (p=0.00). The area under the ROC curve for platelet-derived indices showed that they were adequate for defining the causes of thrombocytopenia. MPV and platelet-large cell ratio had an area under the curve of 0.89 and 0.88, respectively, while platelet size deviation width had an area under the curve of 0.903.

Conclusions. Platelet-derived indices could be useful in the initial approach for the differential diagnosis of pediatric patients with thrombocytopenia.
Nav1.5 cardiac sodium channels, regulation and clinical implications
Authors: León Ariza Henry Humberto , Valenzuela Faccini Natalia , Rojas Ortega Ariana Carolina , Botero Rosas Daniel Alfonso
Published: June 2015

Voltage-gated sodium channels constitute a group of membrane
proteins widely distributed thought the body. In the heart, there
are at least six different isoforms, being the Nav1.5 the most
abundant. The channel is composed of an α subunit that is formed
by four domains of six segments each, and four much smaller β
subunits that provide stability and integrate other channels into
the α subunit. The function of the Nav1.5 channel is modulated
by intracellular cytoskeleton proteins, extracellular proteins,
calcium concentration, free radicals, and medications, among
other things. The study of the channel and its alterations has
grown thanks to its association with pathogenic conditions such
as Long QT syndrome, Brugada syndrome, atrial fibrillation,
arrhythmogenic ventricular dysplasia and complications during
ischemic processes.

The patient underwent a distal pancreatectomy using an
intraoperative ultrasound, resulting in the disappearance of
her symptoms.
Approaches and perspectives to toxicogenetics and toxicogenomics
Authors: Castiblanco Rodriguez Ana Lucia
Published: June 2015

Toxicology is one of the scientific disciplines that has most
evolved in recent years due to scientific and technological
advances that have created a deeper understanding of the
genetic and molecular basis for appreciative variability in
toxic response from one person to another. The application
of this knowledge in toxicology is known as toxicogenetics
and toxicogenomics. The latter is the discipline that studies
the genomic response of organisms exposed to chemical
agents, including drugs, environmental pollutants, food
additives, and other commonly used chemical products.
The use of emerging omic technologies, such as genomics,
transcriptomics, proteomics, metabolomics and bioinformatics
techniques, permits the analysis of many variants of genes
simultaneously in an organism exposed to toxic agents in order
to search for genes susceptible to damage, to detect patterns
and mechanisms of toxicity, and determine specific profiles
of gene expression that give origin to biomarkers of exposure
and risk. This constitutes predictive toxicology.
Cooling water for Britain's future electricity supply

Published: June 2015

Trends in the locations and technologies of UK electricity generation plant suggest that demand for cooling water abstractions from rivers will decrease in the coming decades, unless there is widespread uptake of carbon dioxide capture and storage (CCS). CCS may prove to be essential if the UK is to achieve its carbon dioxide and greenhouse gas emission targets. ‘Decarbonisation’ strategies that rely on CCS are therefore potentially at risk of not having sufficient cooling water in periods of low river flows. In this paper, regional freshwater demands for cooling water are assessed against regional freshwater availability at low flows in a scenario of medium climate change. In the strategy with high CCS, demands for water greatly exceed current and future availability in the north-west (NW) England, Humber, East (E) Midlands and Thames regions. These risks can be mitigated by increasing the penetration of hybrid cooling systems or shifting generating capacity to estuaries or the coast. The former could reduce national water use by up to 35%, whereas applying the latter in the NW England, Humber and E Midlands regions offers nationwide reductions from 30 to 50%.
The Income-Achievement Gap and Adult Outcome Inequality
Authors: Nielsen Eric R.
Published: June 2015

This paper discusses various methods for assessing group differences in academic achievement using only the ordinal content of achievement test scores. Researchers and policymakers frequently draw conclusions about achievement differences between various populations using methods that rely on the cardinal comparability of test scores. This paper shows that such methods can lead to erroneous conclusions in an important application: measuring changes over time in the achievement gap between youth from high- and low-income households. Commonly-employed, cardinal methods suggest that this "income-achievement gap" did not change between the National Longitudinal Surveys of Youth (NLSY) 1979 and 1997 surveys. In contrast, ordinal methods show that this gap narrowed substantially for reading achievement and may have narrowed for math achievement as well. In fact, any weighting scheme that places more value on higher test scores must conclude that the reading income-achievement gap decreased between these two surveys. The situation for math achievement is more complex, but low-income students in the middle and high deciles of the low-income math achievement distribution unambiguously gained relative to their high-income peers. Furthermore, an anchoring exercise suggests that the narrowing of the income-achievement gap corresponds to an economically significant convergence in lifetime labor wealth and school completion rates for youth from high- and low-income backgrounds.
EVALUATION OF WATER ENERGETIC MODES OF ZHIGULEVSKAYA GYDROELECTRIC POWER STATION AND CORRELATION BETWEEN ELECTRIC ENERGY GENERATION AND WATER DISHARGE
Authors: MASLIKOV Vladimir Ivanovich , SIDORENKO Gennady Ivanovich
Published: June 2015

Evaluation of water energetic modes of Zhigulevskaya Hydroelectric Power Station is performed. It is found that operating modes are not always strictly in accordance with requirements for maintaining of water level in head water as well as with water discharge in tail water during the period of spring fl ood, summer-, autumn- and winter runoff low. Evaluation results point to the need for review of the Rules of water management. Analysis of real operating modes of Zhigulevskaya Hydroelectric Power Station shows that long-time annual electric energy generation and guaranteed monthly mean capacity in winter period exceed design specifi cation. Stable statistic patt erns of energy indexes and water discharge characteristics are defi ned. These patt erns can be applied for predicting of electric energy generation by Zhigulevskaya Hydroelectric Power Station taking into account climatic water changes.

Published: June 2015

El claustro de San Pedro el Viejo de Huesca conserva un legado artístico con fuertes implicaciones litúrgicas y funerarias aún por precisar. Antes de abordar dichas líneas de estudio abiertas, era necesaria una revisión general de las modificaciones estructurales del monasterio, incidiendo particularmente en la restauración practicada hacia 1890. En el presente trabajo se documenta la historia de la restauración, se describe la planta actual del edificio, y por último, a través del reconocimiento y cotejo de fuentes, se presenta una aproximación a la campaña románica de la abadía.
Esplendor y ruina de un paradigma. Lo relacional: París-Madrid, Madrid-León
Authors: Albarrán Diego Juan
Published: June 2015

El objetivo de este artículo es analizar el nacimiento de la estética relacional como propuesta teórica y paradigma institucional a partir de los escritos y programas expositivos desarrollados por Nicolas Bourriaud desde finales de los años noventa, revisando al mismo tiempo las críticas recibidas por dicho paradigma en el contexto de una problemática articulación de lo estético, lo artístico y lo político. Acto seguido, estudiaremos hasta qué punto y desde qué presupuestos se produce un trasvase de ciertos aspectos de la estética relacional al ámbito institucional español y castellanoleonés, centrándonos en el caso concreto del MUSAC y constatando a su vez la existencia de una tradición relacional española.
Acción surrealista y medios de intervención. El surrealismo en las revistas, 1919 – 1929
Authors: Mañero Rodicio Javier
Published: June 2015

Las revistas son elementos imprescindibles del complejo entramado surrealista. Aun siendo hoy perfectamente conocidas y ampliamente utilizadas en los estudios sobre aquel movimiento, caben todavía, muy particularmente en lengua española, análisis centrados específicamente en el conjunto de aquellas publicaciones.  Tal es el objetivo del presente estudio, aplicado a establecer un relato articulado del devenir del surrealismo, siempre al hilo de los avatares editoriales y la descripción detallada de las revistas. En esta su primera entrega se aborda la década en la que el surrealismo, inserto en el ambiente dadaísta, se forma alrededor de la revista Littérature y madura en La Révolution surrealiste. El conflictivo Segundo manifiesto del surrealismo cierra este periodo en 1929.

Hacia la renovación escultórica de la segunda mitad del siglo XI. Los ejemplos del sarcófago de San Martín de Dumio y de la pila bautismal de San Isidoro de León
Authors: Fernández González Etelvina
Published: June 2015

La renovación de la plástica escultórica efectuada en los Reinos del Noroeste hispano hasta finales del siglo XI es muy compleja. De ese período se conservan pocas muestras. Se trata, fundamentalmente, de relieves, de obras relacionadas con la función litúrgica y de objetos suntuarios tales como cruces y arquetas relicario. Se ha prestado mayor atención a dos piezas señeras de este arco temporal: el sarcófago de San Martín de Dumio y la pila bautismal de San Isidoro de León. En ambas obras se han analizado los programas iconográficos que las ornan buscando las fuentes textuales en las que se han inspirado. Especial hincapié se hace en las repercusiones que, a nuestro entender, ha tenido la liturgia hispana a la hora de componer los programas iconográficos de la pila bautismal leones.
Santa María de Huerta, panteón de la nobleza castellana
Authors: López de Guereño Sanz María Teresa
Published: June 2015

El monasterio de Santa María de Huerta se convirtió, durante la Edad Media, en la morada eterna de miembros de las más nobles familias castellanas. Desde el último tercio del siglo XII, la comunidad hortense recibió por parte de ellos fuertes ingresos para ejecutar sus obras, a condición de que se les concediese sepultura entre sus muros. Los monjes, a su vez, y en agradecimiento a las donaciones de sus benefactores, se obligaban a rezar por sus almas y custodiar sus sepulcros. En la iglesia, Martín de Finojosa, Rodrigo Jiménez de Rada y los Condes de Medinaceli; en el claustro, anhelando un enterramiento de prestigio, las familias de los Molina, Bera, Montuenga, etc., contribuyeron con sus donaciones y sepulcros a hacer realidad el esplendor de la fábrica monástica y, al mismo tiempo, al alejamiento del ideal monástico de pobreza y austeridad promulgado por los fundadores de la orden
El atrio de la Catedral de León. Edificación, polémica y reclamaciones de una obra singular de finales del siglo XVIII

A finales del siglo XVIII el cabildo de la catedral de León decidió sustituir el viejo pretil que cerraba el atrio por otro nuevo más artístico. El encargado de realizarlo fue el arquitecto Fernando Sánchez Pertejo, quien proyectó un cierre con rejería para este espacio singular. La construcción estuvo plagada de polémicas, unas artísticas y otras técnicas, en las que tuvo que intervenir la Real Academia de Bellas Artes de San Fernando. La obra es el resultado de una concepción artística finisecular, que quiere abandonar la tradición y entrar en la modernidad.

La fotografía como herramienta crítica ante la evolución urbanística y arquitectónica de Salamanca: de la posguerra a la Capitalidad Cultural
Authors: Albarrán Diego Juan , Núñez Izquierdo Sara
Published: June 2015

En el presente artículo se analiza la evolución de la imagen de Salamanca desde un punto de vista simbólico, socio-político y cultural. Este recorrido arranca en el primer franquismo y se extiende hasta la actualidad,tomando como principales referencias una serie de proyectos fotográficos que han planteado visiones críticas de la ciudad y de sus transformaciones urbanísticas y arquitectónicas. Nos detendremos en dos épocas en que la ciudad ha experimentado importantes cambios motivados por imperativos políticos y económicos: la posguerra, período en que Salamanca alcanza un lugar significativo en el ideario del régimen franquista, y un presente definido por la pujanza turística. Veremos cómo, en ambos momentos, varios artistas recurren a la fotografía para llevar a cabo una crítica visual de una urbe en continuo cambio.

La presencia del gigante en el ciclo amadisiano: Un paradigma antroponímico caballeresco
Authors: Coduras Bruna María
Published: June 2015

Resumen

El gigante o jayán es un tipo constante en los libros de caballerías. Simbolizando la desmesura, la soberbia y la brutalidad, representa el mal y se opone al caballero, arquetípicamente virtuoso. En esta ocasión, nos proponemos analizar su presencia en el ciclo amadisiano para, desde él, extraer una poética antroponímica propia de la raza gigantea extensible a todo el género caballeresco.

Palabras clave: Gigante, antroponimia, libros de caballerías, ciclo amadisiano.

 

Abstract

The giant or jayán is a constant type in romance of chivalry. Symbolizing savageness, arrogance and brutality, represents evil, opposite the knight, vitue’s archetype. On this occasion, we analyze the giant’s presence in the Amadisian cycle, deducing an anthroponimic poetics of giants extensible to all of the chivalric genre.

Key words: Giant, anthroponymy, chivalric romances, Amadisian cycle.

En el marco de un estudio de clasificación del paisaje de la provincia de Huelva (Andalucía) mediante un método objetivo, reproducible y escalable de identificación y caracterización de unidades de paisaje, se ha planteado la utilidad del método para una clasificación a nivel de detalle de uno de los tipos de paisajes resultantes. El tipo de paisaje seleccionado ha sido el denominado Campiñas, con una extensión de 1086 km2. La metodología utilizada ha combinado herramientas propias de los sistemas de información geográfica (SIG) y el análisis multivariante de clasificación TWINSPAN (análisis de especies indicadoras de doble vía), así como el análisis de ordenación DCA (análisis de correspondencias). Las variables utilizadas han sido: usos y coberturas vegetales del suelo, municipios y pendiente. Los resultados obtenidos han sido sometidos a validación mediante análisis discriminante y a un proceso de depuración a nivel gráfico.Como resultado del estudio se han identificado tres unidades de paisaje dentro del tipo Campiñas, se han delimitado cartográficamente y se han identificado las variables diagnósticas propias de cada una de ellas. La mayoría de las variables indicadoras han sido relativas a los usos del suelo, mientras que la variable de pendiente no ha sido de valor significativo para tal diferenciación. El análisis gráfico de ordenación ha permitido constatar características de las unidades de paisaje no deducibles del TWINSPAN y que complementan la información derivada del mismo. Los resultados del análisis discriminante validan la clasificación realizada. Se justifican las variables utilizadas y se compara la metodología seguida con otros enfoques automatizados, así como los resultados de la clasificación con los obtenidos en la clasificación del Atlas de los Paisajes de España. Por último se concluye la utilidad de la metodología seguida, TWINSPAN, para una clasificación de paisajes a nivel de detalle, analizándose las razones de esta idoneidad.

For a long time, studies concerning erosion caused by concentrated overland flow mainly dealt with the erosion and the transport of fine material. More recent studies have shown that rock fragments reduce the intensity of soil erosion processes on the one hand, but on the other hand rock fragment movements also have been observed both in the rill- and interrill erosion processes. However, there is little knowledge about the movement process of rock fragments in shallow channel flow. Are certain movement patterns typical for different shapes? Are there relationships between movement patterns and slope and flow velocity? Are all these patterns and relationships reproducible? To answer these questions, we performed laboratory channel experiments. With these experiments, we could obtain information about movement patterns of pebbles, by varying the following parameters: shape (flat, ellipsoidal, nearly spherical), size (diameter between 1.97 and 4.0 cm) and channel slope (5°, 10°). During the experiments, a high-speed camera was used to capture the motion of eight specially painted pebbles. The resulting image sequences were processed using both automatic image processing and manual visual inspection. Besides the movement patterns, the pebbles velocity, the water velocity and the water depth were estimated. We could show that there were different movement patterns depending on the shape and the slope. For the 5° experiments, the big, flat pebbles lie at the beginning of the tests. After the following yawing, the pebbles mainly showed the movement form rolling around the longest axis. For the 10° experiments the big, flat pebbles showed the same movement pattern firstly, but later in the sequence, they started to roll around their shortest axis and in the end this movement form was combined with saltation. These patterns are described using a simple symbolic language: sequences of pictograms describe the consecutive movement forms. Furthermore, we detected five different velocity groups of the pebbles for each slope: different cross-section shapes of the pebbles result in different acceleration behavior. The methodology is limited to clear water in laboratory use. Even a larger water depth restricts the image processing. Thus, in the future the experiments will be combined with a small sensor that is implanted in the pebbles and measures forces (acceleration), compass (magnetic flux density) and rotations (gyroscope).

O fornecimento adequado de nutrientes é fundamental, sendo que o N para a alface está diretamente associado as características vegetativas, reprodutivas e morfológicas. O experimento foi conduzido no setor de Olericultura da Universidade Federal do Tocantins (UFT), na cidade de Gurupi. Foram utilizadas duas cultivares<span style="color: #222222; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;">, Elba e Verônica. As mudas foram produzidas em bandejas de isopor de 128 células. Aos 27 dias após o transplantio, foram avaliadas as seguintes características: Massa fresca aérea (MFA) - Obtida com a pesagem das plantas coletadas; Número de folhas totais (NFT) - Através da contagem das folhas das planta; Diâmetro da cabeça (DC) - Obtido com auxilio de uma régua; Massa seca aérea (MSA) – Obtida através da secagem da massa verde em estufa a 60° C, ate atingir peso constante, quando as amostras foram pesadas novamente. Podemos destacar que a cv. Elba apresentou bom desenvolvimento para as características de diâmetro de cabeça. Já a cv. Verônica obteve destaque em massa fresca e massa seca aérea, a medida que se aumentava as doses de N. Fica evidenciada a queda na produção a partir de determinada dose.<span style="font-size: 12.0pt; line-height: 115%; font-family: 'Times New Roman','serif'; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-ansi-language: PT-BR; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;">Os resultados das variáveis estudadas neste trabalho demonstraram resposta quadrática em relação à aplicação de doses de adubação nitrogenada na forma de ureia.

Os lixões urbanos são práticas antigas e constantes nas cidades brasileiras, nas quais os resíduos sólidos são depositados em locais inadequados e sem qualquer tratamento, o que vem a ocasionar impactos para a população, a saúde pública e o meio ecológico. Neste trabalho teve- se como objetivo elaborar um diagnóstico qualitativo da degradação ambiental na área do lixão de Pombal-PB. A metodologia teve por base a realização de visitas de campo, entrevistas aos gestores do município, catadores da área do lixão e moradores no entorno da área em estudo. Fez-se a identificação dos impactos ambientais utilizando-se os métodos Ad Hoc e Check Lists, e proposição de medidas voltadas à recuperação da área. De acordo com os resultados, observou-se que os principais impactos diagnosticados foram: a contaminação do solo, dos recursos hídricos, do ar atmosférico; o aumento dos processos erosivos; redução ou perda total da fauna e flora; riscos aos catadores e impacto na saúde pública. Os fatores mais afetados foram o antrópico, o solo, a fauna, a flora e a paisagem. Propôs-se a biorremediação e o reflorestamento para a recuperação da área, cujo uso final indicado foi área de preservação.

O presente teve como objetivo estudar o efeito da estocagem congelada de massas por até 60 dias nos parâmetros colorimétricos de pães tipo forma. Foram desenvolvidas 7 formulações de pães tipo forma, uma padrão, sema adição de ingredientes funcionais e as  contendo as combinações dos ingredientes açaí em pó/polidextrose, brócolis em pó/polidextrose e tomate em pó/polidextrose nas proporções de 5% e 10% cada. Através de análise de cor instrumental foram avaliados os parâmetros de luminosidade (L), cromaticidades a* e b*, o croma (C*) e o ângulo de tonalidade (h°) do miolo dos pães nos tempos 0, 15, 30, 45 e 60 dias. Para a formulação padrão, a luminosidade apresentou redução de  77,38 a 69,43, houve redução na cromaticidade a* e ângulo de tonalidade, já a cromaticidade b* e croma apresentaram elevação em função do tempo de estocagem. Para as formulações contendo ingredientes funcionais, o comportamento foi semelhante, os pães tiveram menor luminosidade quando comparada à padrão, à medida do tempo de estocagem, pela degradação dos pigmentos houve elevação deste parâmetro. A cromaticidade a* e o ângulo de tonalidade foram reduzidos ao longo da estocagem, com exceção das formulações incorporadas com brócolis em pó, onde o ângulo de tonalidade aumentou. A cromaticidade b* e o croma apresentaram aumento durante o período estudado. Concluiu-se que o tempo de estocagem congelada das massas promoveu variações nos parâmetros colorimétricos do miolo de pães tipo forma.
