Abstract:
Abstract Autoimmune diseases are devastating, incurable disorders that affect over 20 million people in the US, and many of these disorders have a striking female bias. The genetic basis for this sex-bias arises from the X chromosome. Female mammals, with two X chromosomes, utilize the epigenetic process of X Chromosome Inactivation (XCI), which transcriptionally silences one X. Expression of the long noncoding RNA Xist from the inactive X (Xi) reorganizes the Xi into a compact, bipartite structure, and targets the Xi to the nuclear periphery in somatic cells. The paradigm of XCI maintenance in somatic cells is stable association of Xist RNA and heterochromatic marks on the Xi, which function to maintain the Xi structure. Recently, we found a dynamic mechanism of XCI maintenance in female lymphocytes. In naïve female B cells, Xist RNA is not localized to the Xi, but after stimulation Xist RNA and heterochromatin marks return to the Xi. How this dynamic XCI process impacts Xi structure in lymphocytes is unknown, including which factors regulate Xi nuclear organization in this system. Using a novel allele-specific imaging system, we will present new findings on the compaction and organization of the Xi in lymphocytes. Additionally, we are investigating the regulatory roles of chromatin organization and nuclear structure proteins for lymphocyte-specific XCI maintenance, and how these factors regulate X-linked gene expression. Together, these results underscore the importance of Xi structure for the fidelity of XCI in female lymphocytes.

AbstractLet $X$ be a Banach space and $\xi$ an ordinal number. We study some isomorphic classifications of the Banach spaces $X^\xi$ of the continuous $X$-valued functions defined in the interval of ordinals $[1,\xi]$ and equipped with the supremum norm. More precisely, first we use the continuum hypothesis to give an isomorphic classification of $C(I)^\xi$, $\xi\geq\omega_1$. Then we present a characterization of the separable Banach spaces $X$ that are isomorphic to $X^\xi$, $\forall\xi$, $\omega\leq\xi lt \omega_1$. Finally, we show that the isomorphic classifications of $(C(I)\oplus F^*)^\xi$ and $\ell_\infty(\N)^\xi$, where $F$ is the space of Figiel and $\omega\leq\xi lt \omega_1$ are similar to that of $\R^\xi$ given by Bessaga and Pelczynski.AMS 2000 Mathematics subject classification: Primary 46B03; 46B20; 46E15

Abstract:
Polycomb group (PcG) proteins belonging to the polycomb (Pc) repressive complexes 1 and 2 (PRC1 and PRC2) maintain homeotic gene silencing. In Drosophila, PRC2 methylates histone H3 on lysine 27, and this epigenetic mark facilitates recruitment of PRC1. Mouse PRC2 (mPRC2) has been implicated in X inactivation, as mPRC2 proteins transiently accumulate on the inactive X chromosome (Xi) at the onset of X inactivation to methylate histone H3 lysine 27 (H3-K27). In this study, we demonstrate that mPRC1 proteins localize to the Xi, and that different mPRC1 proteins accumulate on the Xi during initiation and maintenance of X inactivation in embryonic cells. The Xi accumulation of mPRC1 proteins requires Xist RNA and is not solely regulated by the presence of H3-K27 methylation, as not all cells that exhibit this epigenetic mark on the Xi show Xi enrichment of mPRC1 proteins. Our results implicate mPRC1 in X inactivation and suggest that the regulated assembly of PcG protein complexes on the Xi contributes to this multistep process.

Abstract:
Introduction . Inactive X chromosome (Xi) is associated with noncoding XIST RNA, series of proteins and contains multiple epigenetic modifications that altogether determine a silence of the most of X-linked genes. Recently the data were obtained that tumor suppressor BRCA1 is also associated with Xi. The purpose of this study was to reveal the colocalization of BRCA1 and XIST RNA and precise spatial organization on Xi with the high resolution of confocal microscopy.Materials and methods . The object of the study is IMR90hTERT diploid immortalized fibroblast cell line. For BRCA1 and XIST RNA colocalization analysis on Xi the method of fluorescent hybridization in situ associated with immunofluorescent cell staining (immunoFISH) and confocal microscopy were used. For BRCA1 and heterochromatin protein-1 colocalization study the method of double immunofluorescent staining and common fluorescent microscopy were applied. Results . The study using confocal fluorescent microscopy with higher resolution has demonstrated at first the colocalization of BRCA1 with XIST RNA region of Xi revealed with XIST RNA probes and with replicating Xi and autosomes revealed with BrdU in late S-phase of cell cycle. Altogether, the data obtained suggest the involvement of BRCA1 in the inhibition of gene expression on Xi due to the regulation of XIST RNA association with Xi. Moreover, according to the results of confocal microscopy, BRCA1 also colocalizes with replicating Xi and autosomes revealed with BrdU in late S-phase of cell cycle. This indicates a possible involvement of this protein in the replication of pericentromeric repeats in cellular chromosomes. Colocalization of BRCA1 with heterochromatin protein-1α presented in pericentromeric regions of all chromosomes supports this suggestion.Conclusions . Altogether, the data obtained in this study suggest the involvement of BRCA1 in the inhibition of gene expression on Xi due to the association with noncoding inhibiting XIST RNA and in replication of heterochromatin regions.

Abstract:
The histone macroH2A1.2 has been implicated in X chromosome inactivation on the basis of its accumulation on the inactive X chromosome (Xi) of adult female mammals. We have established the timing of macroH2A1.2 association with the Xi relative to the onset of X-inactivation in differentiating murine embryonic stem (ES) cells using immuno-RNA fluorescence in situ hybridization (FISH). Before X-inactivation we observe a single macroH2A1.2-dense region in both undifferentiated XX and XY ES cells that does not colocalize with X inactive specific transcript (Xist) RNA, and thus appears not to associate with the X chromosome(s). This pattern persists through early stages of differentiation, up to day 7. Then the frequency of XY cells containing a macroH2A1.2-rich domain declines. In contrast, in XX cells there is a striking relocalization of macroH2A1.2 to the Xi. Relocalization occurs in a highly synchronized wave over a 2-d period, indicating a precisely regulated association. The timing of macroH2A1.2 accumulation on the Xi suggests it is not necessary for the initiation or propagation of random X-inactivation.

Abstract:
Breast cancer, early onset 1 (BRCA1) encodes a nuclear protein that participates in breast and ovarian cancer suppression. The molecular basis for the gender and tissue specificity of the BRCA1 cancer syndrome is unknown. Recently, we observed that a fraction of BRCA1 in female cells is localized on the inactive X chromosome (Xi). Chromatin immunoprecipitation (ChIP) experiments have demonstrated that BRCA1 physically associates with Xi–specific transcript (XIST) RNA, a non–coding RNA known to coat Xi and to participate in the initiation of its inactivation during early embryogenesis. Cells lacking wild–type BRCA1 show abnormalities in Xi, including lack of proper XIST RNA localization. Reintroduction of wild–type, but not mutant, BRCA1 can correct this defect in XIST localization in these cells. Depletion of BRCA1 in female diploid cells led to a defect in proper XIST localization on Xi and in the development of normal Xi heterchromatic superstructure. Moreover, depletion of BRCA1 led to an increased likelihood of re–expression of a green fluorescent protein (GFP) reporter gene embedded on Xi. Taken together, these findings are consistent with a model in which BRCA1 function contributes to the maintenance of proper Xi heterochromatin superstructure. Although the data imply a novel gender–specific consequence of BRCA1 loss, the relevance of the BRCA1/Xi function to the tumour suppressor activity of BRCA1 remains unclear and needs to be tested.

Abstract:
La comarca del Vallès era, als segles X i XI, el rerepaís del comtat de Barcelona; estava sota el control dels seus sobirans, però prou lluny de la capital com per desenvolupar unes dinàmiques autònomes. D’aquest territori s’ha conservat una quantitat molt considerable de documentació medieval original en els seus riquíssims arxius d’institucions civils i eclesiàstiques. Mercès a aquestes dues característiques és un espai idoni per intentar identificar-hi unes persones concretes, els escrivans: aquells que amb la seva signatura validaven els documents per donar-los caràcter públic. L’estudi s’organitza en tres seccions. La primera dedicada a la descripció de les fonts documentals i la metodologia emprada per obtenir i processar la informació. En la segona s’identifiquen els escrivans: es presenta l’inventari i estudi dels individus, així com la prosopografia d’una quarantena d’ells. La tercera secció se centra en la topografia vinculada als escrivans, mostrant les fonts d’informació i les eines utilitzades per analitzar-les, així com els resultats cartogràfics i l’elaboració de les fitxes d’unitat topogràfica que permeten intuir com es relacionaven els escrivans amb el territori. Es constata que als segles X i XI la immensa majoria dels escrivans són clergues seculars, dels quals es pot seguir en alguns casos la carrera eclesiàstica. Al segle X el clergat regular és pràcticament absent, mentre que figuren signant una petita proporció de documents el segle XI. Inversament, al segle X hi ha una contingent significatiu d’escrivans laics, que al segle XI es redueix notablement. Es conclou que els escrivans actuaven donant validesa als documents en actes performatius, no merament assertius, en virtut d’una autoritat pública que distingia els oficis i tenia per incompatibles els de jutge i escrivà. Homogeneïtat en els tipus documentals, llargues trajectòries, àmplia presència distribuïda per tot el territori i, sobretot, la capacitat de canviar el vocabulari en un reduït espai de temps, indiquen que hi ha un vincle estable entre l’autoritat pública i els escrivans molt abans de la recepció del Dret Comú i de la implantació de la institució del notariat. Es destaca que en el transcurs de la quarta dècada del segle XI hi hagué un ràpid canvi en el vocabulari emprat per designar els llocs de culte i llurs espais adjacents, amb el que s’introduí un nou formulari, generat en un context teològic carolingi. Probablement fou el resultat de l’execució d’un pla procedent de l’autoritat comtal, en concret d’Ermessenda de Carcassona, acompanyada pel jutge Bonshom i els bisbes Pere Roger de Girona i Oliba de Vic, que el 1038 consagraren les seves respectives catedrals. A la ciutat de Barcelona també es documenta aquest canvi en el vocabulari, a Santa Maria del Mar on, amb motiu de la renovació de la canònica catedralícia, entre el 1009 i el 1019, hi hagué una intervenció directa dels comtes. Pocs anys després, amb la revolta dels senyors de la marca a mitjan segle XI, els escrivans seguiren actuant al servei d’una autoritat de natura pública, i llur funció serví per consolidar les noves relacions socials i econòmiques fonamentades en l’ús privat de la violència, que fou instrumentalitzada també a través dels documents escrits.
During the 10th and 11th centuries, the Vallès region was the hinterland of the County of Barcelona: it was under the control of its sovereigns, but far enough from the capital to develop autonomous dynamics. A large quantity of original medieval documentation from this territory has been preserved in the rich archives of its ecclesiastic and civilian institutions. As a result, it is the ideal place to identify certain people, the scribes - those who authenticated documents with their signature in order to make them public. The present study is divided into three sections. The first focusses on the description of documentary sources and the methodology used to obtain and process the information. In the second, the scribes are identified, presenting an inventory and study of each of them, as well as a prosopography of about forty of them. The third section focusses on the topography linked to these scribes, showing the information sources and tools used for the analysis, as well as cartographic results and files of the topographic units that allow us to sense how the scribes were connected with the territory. Evidence shows that during the 10th and 11th centuries the great majority of the scribes were secular clerics, and the ecclesiastic career of some of them can be followed through the sources. During the 10th century, regular clergy are practically absent, while they appear signing a small proportion of documents in the 11th century. Inversely, during the 10th century there is a significant contingent of secular scribes, which reduced considerably during the 11th century. It can be concluded that the scribes authenticated the documents in performative acts, not merely assertive ones, by virtue of a public authority that distinguished the professions and made incompatible that of the judge and that of the scribe. Documentary homogeneity, long careers, a wide presence over the territory and, above all, the ability to change vocabulary in a short time span, are signs that there was a stable link between the public authority and the scribes long before the reception of the Jus commune and the introduction of the notary institution. During the course of the fourth decade of the 11th century there was a rapid change in the vocabulary used to designate holy places and adjacent spaces, a new form generated in a Carolingian theological context. It was probably the result of the executed plan of the count authority, promoted specifically by Ermessenda of Carcassone, and accompanied by the judge Bonshom and the bishops Pere Roger of Girona and Oliba of Vic, who consecrated their respective cathedrals in 1038. In Barcelona, a change of vocabulary can be found too, in this case at Santa Maria del Mar. There, on the occasion of the renovation of the Canonical cathedral (between 1009 and 1019), a direct intervention of the counts can be attested. A few years later, during the rebellion of the lords of the March in the middle of the 11th century, the scribes continued acting under the rule of a public authority. Their function was used to consolidate the new social and economic connections, based on the private use of violence, which was exploited too through written documents.

The subject of this work is to study and compute the elasticity of the type R=A+XI[X] domains where I is an ideal of an integral domain A. In a first chapter, we compute the elasticity of R is finite if and only if the ideal I is a product of distinct primes ideals which one all principal but at most one. On the other hand, we compute the elasticity of R according to the GCD decomposition of I. We finish by showing that the elasticity of R can't be realised by a factorisation (except if R is HFD). In the second chapter, we investigate the elasticity of R when A is a Dedekind domain. First, we prove that its elasticity is finite if and only if the elasticity of A is finite and I is a radical ideal. Then we bound the elasticity of R using the number of prime ideal in the factorisation of I and some Davenport-type constants. In some special cases we derive the exact value of the elasticity. In the last chapter, we investigate the elasticity of domains of the type R=A+XI(1) ++XI(k)[X]. We obtain some necessary conditions for the elasticity to be finite when A is integrally closed and some sufficient conditions when A is ACCP. We finish by proving that when A is a UFD or a Dedekind domain, the elasticity of R is finite if and only if the elasticity of T= A+XI(k) [X] est finie et les quotients [I(k)/I(i)] sont finis

Abstract:
RESUMO: Cerâmica Islâmica: comércio e tecnologia no sul do Gharb al-Andalus (Seculos X-XI) A produção de cerâmica vidrada na Península Ibérica foi generalizada durante o período islâmico. Durante este período, a técnica do vidrado era caracterizada pelo uso de chumbo como principal fundente, para além de coexistirem outras práticas tais como a utilização de fritas e aplicação de soluções de esmalte sobre os corpos cerâmicos calcários cozidos. O principal objetivo do presente estudo é comparar a produção de cerâmica vidrada em Évora com outras cidades, tais como Mértola e Silves, a fim de identificar padrões de produção, contactos regionais e a proveniência dos materiais durante a ocupação Islâmica. Assim, selecionou-se um conjunto de exemplares constituídos por vidrados monocromáticos e de decoração melada e manganês desses três locais, sendo este submetido a análises multielementares. Microscopia ótica (OM), difração raio-X (XRD) e fluorescência de raio-X (XRF) foram as análises aplicadas para determinar as características das pastas cerâmicas, assim como o processo de produção e a proveniência das matérias-primas. O recurso ao Microscópio Eletrónico de Varrimento acoplado a um Espectrómetro Dispersivo de Energia (SEM-EDS) foi crucial para determinar a microestrutura e a composição química do vidrado e da decoração a manganês, a fim de avaliar a técnica de produção do vidrado; Glazed pottery production in the Iberian Peninsula was widespread during the Islamic period. During this time, the glaze recipe was characterized for the main use of lead as flux, besides other common practice such as the employment of frits and the application of the glaze suspension over biscuit-fired calcareous ceramic bodies. The main goal of the present study is to compare the glazed pottery production in Évora with other cities, such as Mértola and Silves, for identifying patterns of production, regional contacts and provenance of the products during the Islamic occupation. Thereby, a set of specimens which consist of monochromatic and black-decorated dichromatic honey glazes and coarsewares were retrieved from those three places and subjected to multi-elemental analysis. Optical Microscopy (OM), X-ray Diffraction (XRD), X-ray Fluorescence (XRF) analyses were applied to determine the ceramic bodies characteristics, shedding light on the production process and the provenance of the raw materials. Scanning Electron Microscope coupled to an Energy Dispersive Spectrometer (SEM-EDS) analysis were used to determine the microstructure and the chemical composition of the glaze and black decoration to evaluate glaze technology.

Abstract:
This study focused on the attitude of the Catholic Church towards Jews and Protestants from the pontificate of Pius X, until that one of Pius XI. Hostility towards Jews and Protestants by the Catholic Church seems to be a constant of Italian Catholicism from the sixteenth century until the end of the Second World War, despite the presence of specific adjustments and revisions due to different historical contexts in which it appears. In the Catholic world the images of "the Jew" and "the Protestant" are inherent to the relationship between Catholicism and modernity. According to the nineteenth century Catholic conservative positions a model of societas christiana had been broken by the political, economic and social upheavals that occurred in Europe since the French Revolution. Attempting to rebuilt that model of christianitas, the anti-Jewish and anti-Protestant positions emerge as a reaction against the "enemy" of modernity, which operates, in the Catholic point of view, for the de-Christianization of society. Therefore, both the Protestant and the Jew are considered as the leaders of that "conspiracy" which aims at the collapse of Catholic institutions. Based to these facts, my research focuses on the first three pontificates of the twentieth century, reviewing the most significant events, documents and statements of the Holy See, of the episcopacy of Veneto and of diocesan magazines.
Questo lavoro ha avuto come oggetto di studio l'atteggiamento della Chiesa cattolica verso gli ebrei e i protestanti dal pontificato di Pio X a quello di Pio XI. L'ostilità nei confronti di ebrei e protestanti da parte della Chiesa cattolica risulta essere, in realtà, una costante del cattolicesimo italiano dal XVI secolo fino al secondo dopoguerra, pur in presenza di specifici adattamenti e rimodulazioni dovuti ai diversi contesti storici in cui essa si realizzò. Le immagini dell'ebreo e del protestante nel mondo cattolico sono connaturate al rapporto tra cattolicesimo e modernità: nel tentativo di ricostruire e difendere un modello di societas christiana, che, secondo l'intransigentismo ottocentesco, gli sconvolgimenti politici, economici e sociali manifestatisi in Europa a partire dalla Rivoluzione francese avevano infranto, l'antiebraismo e l'antiprotestantesimo riemergono per contrastare le «forze nemiche» della modernità, che nell'ottica del cattolicesimo, operano per la scristianizzazione della società. Pertanto, sia l'ebreo che il protestante vengono additati come i protagonisti di quella "teoria del complotto" che mira al disfacimento delle istituzioni cattoliche. Ho concentrato l'analisi dei primi tre pontificati del Novecento relativamente a tali questioni, ripercorrendo gli eventi più significativi, gli atti, le prese di posizione della Santa Sede, dell'episcopato veneto e della pubblicistica diocesana.

Abstract:
Cette thèse porte sur l’Explanatio in Calculo Victorii d’Abbon de Fleury, un commentaire aux tables de multiplication de Victorius d’Aquitaine (fl. 450). En considérant l’oeuvre d’Abbon comme le témoin par excellence de la tradition philosophique, que je qualifie d’« arithmétisme théologique », ma thèse se veut une contribution à l’histoire du néo-pythagorisme médiéval des Xe et XIe siècles. Les thèmes suivants y sont abordés : l’interprétation d’Abbon du verset Sap. 11, 21 et son arrière-plan philosophique (ch. III) ; son hénologie (théorie de l’unité) à l’égard de l’unité divine et créée (ch. IV) ; sa conception de la composition – ontologique et matérielle – des créatures (ch. V) ; ses compétences computistes et arithmétiques qui prennent appui sur la théorie boécienne des nombres et sur les méthodes de calcul (ch. VI). Dans le cadre bien néopythagoricien de l’Explanatio, certaines notions péripatéticiennes sont employées par Abbon dans l’étude des phénomènes physiques (ch. VII). De plus, la thèse entend situer la pensée abbonienne dans un contexte culturel qui se caractérise par un renouvellement dans l’étude des arts libéraux, tout particulièrement du quadrivium, qui est favorisé par la redécouverte progressive du De arithmetica de Boèce et par la diffusion en Occident de nouveaux instruments de calcul (ch. I). Les traditions manuscrites de l’Explanatio d’Abbon ainsi que du Calculus de Victorius sont également examinées, dans le but de dégager deux voies possibles par lesquelles l’oeuvre de Victorius est arrivée à l’abbaye de Fleury. Ensuite, on montre la place du commentaire d’Abbon dans l’histoire de l’arithmétique en tant que théorie des nombres autour de l’an mil (ch. II). La thèse étudie les sources philosophiques d’Abbon, tout en analysant sa façon de comprendre et d’harmoniser les différentes approches platoniciennes, notamment d’après le De statu animae de Claudien Mamert, le Commentaire au Timée de Calcidius, le Commentaire au Songe de Scipion et les Saturnalia de Macrobe, le De arithmetica et le De institutione musica de Boèce
This thesis deals with the arithmetical commentary by Abbo of Fleury on the series of multiplication tables ascribed to Victorius of Aquitaine (fl. 450): the Explanatio in Calculo Victorii. My research aims to shed light on the history of medieval Neopythagoreanism between the 10th and 11th centuries, in which Abbo’s work stands as a peculiar testimony of what my work indicates as “theological arithmetism”. The organization of my thesis follows this overall structure. In the first two chapters Abbo’s life and works are presented with a special emphasis on his educational training and learning. Then, the main topics of his “mathematism” are presented, starting with Abbo’s interpretation of the Biblical passage on God who created everything in number, wheight and measure (Wisd. 11, 21), which is discussed at chapter 3, also by illustrating its philosophical background. Then, I present Abbo’s “henology”, namely his consideration of Unity, with regard to both divine and created unity (chapter 4); moving next to his conception of ontological and material compositeness, which Abbo ascribed to creatures (chapter 5) and finally to his arithmetical and computistical knowledge grounded on Boethius’ number theory and his methods of reckoning (chapter 6). To this overall exposition of Abbo’s Neopythagoreanism, it follows a section devoted to Peripatetic approach to the analysis of the natural phenomena (chapter 7). The methodology applied to my research intends to place Abbo’s thought in its cultural context: the renewal of the liberal studies and particularly of the quadrivium, which was stimulated by a progressive rediscovery of Boethius’ De arithmetica together with the introduction of new calculation tools in the Latin West. If this is the general background from which Abbo’s peculiar “Pythagorism” emerges, the philological analysis of his commentary confirms how Fleury was an outstanding centre for high-level mathematical studies. The manuscript tradition of both Abbo’s Explanatio and Victorius’ Calculus, let us envisage two possible paths through which the latter reached Fleury Abbey. A final goal of my work is also to consider Abbo’s commentary within the history of theoretical arithmetics during the first Millennium. Tracking Abbo’s philosophical sources and showing his distinctive comprehension and harmonization of different Platonic accounts, namely those spelt out in Mamertus’ De statu animae, Calcidius’ Commentary on Timaeus, Macrobius’ Commentary on the Dream of Scipio and Saturnalia and Boethius’ De arithmetica and De institutione musica, has been a stimulating research and a confirmation of Abbo’s outstanding role in the not yet sufficiently explored history of high medieval “mathematical” approach to theology and world vision

Abstract:
El propòsit principal d’aquesta tesi és identificar, publicar i analitzar 1.268 documents de l’antic arxiu de Sant Benet de Bages, una abadia benedictina fundada a mitjans del segle X, a la riba dreta del riu Llobregat (a la Catalunya central) per Sala de Conflent, un membre destacat de la noblesa pirinenca, un col•laborador proper dels comtes de Barcelona-Osona-Manresa en la tasca de conquesta i repoblació de la marca occidental en contacte amb al-Andalus. El període tractat comprèn 225 anys, de l’any 898 (data del primer document de propietat que tenia el monestir, fundat més de seixanta anys més tard) fins l’any 1123, quan va recuperar de nou la independència, després de la unió temporal amb Sant Ponç de Tomièras (ca. 1075-1101), d’acord amb el programa de la Reforma Gregoriana. Al llarg d’aquests documents, som capaços de conèixer no tan sols el llarg procés de formació del monestir i els detalls de la seva dotació, sinó també quins foren els seus abats, quants monjos hi va haver i la formació del seu patrimoni. Aquesta tesi aporta una mirada més profonda dels aspectes relacionals intraterritorials i extraterritorials i adquirir un coneixement intensiu en el camp social, polític, econòmic, material, cultural i lingüístic dels comtats catalans durant els segles X i XI i fins el primer quart del segle XII.
El propósito principal de esta tesis es identificar, publicar y analizar 1.268 documentos del antiguo archivo de Sant Benet de Bages, una abadía benedictina fundada a mediados del siglo X en el lado derecho del río Llobregat (en la Cataluña central) por Sala de Conflent, un miembro destacado de la nobleza pirenaica, un colaborador cercano de los condes de Barcelona-Osona-Manresa en la tarea de conquista y repoblación de la marca occidental en contacto con al-Andalus. El período tratado comprende 225 años, desde el año 898 (fecha del primer documento de propiedad que conservaba el monasterio, fundado más de sesenta años más tarde) hasta el año 1123, cuando hubo recuperado nuevamente la independencia original, después de la unión temporal con Sant-Pons-de-Thomières (ca. 1075-1101), de acuerdo con el programa de la Reforma Gregoriana. A lo largo de estos documentos, somos capaces de conocer no solamente el largo proceso de formación del monasterio y los detalles de su dotación, sino también cuáles fueron sus abades, cuantos monjes tuvo y la formación de su patrimonio. Esta tesis aporta una mirada más profunda de los aspectos relacionales intraterritoriales y extraterritoriales y permite adquirir un conocimiento intensivo en el campo social, político, económico, material, cultural y lingüístico de los condados catalanes durante los siglos X y XI y hasta el primer cuarto del siglo XII.
The basic aim of this thesis is to identify, to publish and to analyse 1,268 documents of the ancient archives of Sant Benet de Bages, a benedictine abbey founded in the middle of 10th century in the right side of the Llobregat river (in central Catalonia) by Sala of Conflent, an outstanding member of the nobility of the Pyrenees, a narrow collaborator of the counts of Barcelona-Osona-Manresa in the task of conquest and repopulation of the west mark in contact with Al-Andalus. The period studied covers 225 years, going from the year 898 (date of the first document of property that had the monastery, founded more than sixty years later) to the year 1123, when it recovered again its independence, after temporary union with Saint-Pons-de-Thomières (ca. 1075-1101), according to the program of the Gregorian Reform. Along those documents, we are able to know not only the long process of formation of the monastery and the details of its endowment, but also who were their abbots, how many monks lived there and the building of their patrimony.

Full text
Abstract:
Standard salinity management theory, derived from blending thermodynamic and semi- empirical considerations leads to an erroneous perception regarding compensative interaction among salinity stress factors. The current approach treats matric and osmotic components of soil water potential separately and then combines their effects to compute overall response. With deficit water a severe yield decrease is expected under high salinity, yet little or no reduction is predicted for excess irrigation, irrespective of salinity level. Similarly, considerations of competition between chloride and nitrate ions have lead to compensation hypothesis and to application of excess nitrate under saline conditions. The premise of compensative interaction of growth factors behind present practices (that an increase in water application alleviates salinity stress) may result in collateral environmental damage. Over-irrigation resulting in salinization and elevated ground water threatens productivity on a global scale. Other repercussions include excessive application of nitrate to compensate for salinity, unwillingness to practice deficit irrigation with saline water, and under-utilization of marginal water. The objectives for the project were as follows: 1) To develop a database for model parameterization and validation by studying yield and transpiration response to water availability, excessive salinity and salt composition. 2) To modify the root sink terms of an existing mechanism-based model(s) of water flow, transpiration, crop yield, salt transport, and salt chemistry. 3) To develop conceptual and quantitative models of ion uptake that considers the soil solution concentration and composition. 4) To develop a conceptual and quantitative models of effects of NaCl and boron accumulation on yield and transpiration. 5) To add a user interface to the water flow, transpiration, crop yield, salt transport, chemistry model to make it easy for others to use. We conducted experiments in field plots and lysimeters to study biomass production and transpiration of com (Zeamays cv. Jubilee), melon (Cucumismelo subsp. melo cv. Galia), tomato (Lycopersiconesculentum Mill. cv. 5656), onion (Alliumcepa L. cv. HA 944), and date palms (Phoenix Dactylifera L. cv. Medjool) under salinity combined with water or with nitrate (growth promoters) or with boron (growth inhibitor). All factors ranged from levels not limiting to plant function to severe inhibition. For cases of combined salinity with water stress, or excess boron, we observed neither additive nor compensative effects on plant yield and transpiration. In fact, yield and transpiration at each combination of the various factors were primarily controlled by one of them, the most limiting factor to plant activity. We proposed a crop production model of the form Yr = min{gi(xi), where Yr = Yi ym-1 is relative yield,Ym is the maximum yield obtained in each experiment, Xi is an environmental factor, gi is a piecewise-linear response function, Yi is yield of a particular treatment. We selected a piecewise-linear approach because it highlights the irrigation level where the response to one factor ceases and a second factor begins. The production functions generate response "envelopes" containing possible yields with diagonal lines represent response to Xi alone and the lines parallel to the X-axis represent response to salinity alone. A multiplicative model was also derived approximating the limiting behaviour for incorporation in a hydrochemical model. The multiplicative model was selected because the response function was required to be continuous. The hydrochemical model was a better predictor of field-measured water content and salt profiles than models based on an additive and compensative model of crop response to salinity and water stress.
