Teresa Abelló Poveda Director(Principal) of the Thesis: Dra. Montserrat Colell Mimó TEXT: This research is based on the problems detected in the reproduction and development of great apes and specifically on the ex situ gorilla population (EEP. EAZA), and the need to investigate factors that could improve their breeding success and their development. The subjects of this study are members of a gentle population who has lived throughout several decades, and in some cases still it lives, in captivity and, therefore, under conditions that defer enough from their natural ones in the wild regarding habitat and social life. One of the specific problems detected in the great apes population comes from the considerable number of individuals hand-raised (by human beings) that exists in the historical and current population, and that present some deficiencies in their maternal behaviour, in their social relations, and in their breeding results. For that reason different aspects of the socialization process and social behaviour are analyzed on hand-reared animals, with special incidence on the factors that have some influence on maternal behavior and a successful breeding of individuals when reaching their sexual maturity. The different studies presented are based on the result from surveys (quantitative data), qualitative observations of social behaviour and specific demographic data obtained from the Gorilla European Studbook. The results give a better knowledge a on the acquisition of socila skills on great apes, and more specifically on gorillas, and it is worth to improve exsitu conservation (management/breeding) programmes This research allowed allowed to identify those factors that favor a good maternal profile in captive gorilla females, and for extension in other species of great apes. Revealing some factors of concern for the social development of hand-reared gorillas and determining which are the necessary circumstances to realize the early introduction of the above mentioned individuals in a group of coespecíficos, so that their develop with a adequate social profile and can be introduced without difficulty in other groups of coespecíficos Advisors/Committee Members: false (authoremailshow), Colell Mimó, Montserrat (director), false (authorsendemail).

▼ IRES or Internal Ribosomal Entry Sites are highly structured sequences harbored on the 5' untranslated region (5'-UTR) of several virus and eukaryotic mRNAs that enable an alternative cap-independent translation. Highly conserved in virus genotypes, IRESs are attractive targets to design novel antiviral drugs. A few years ago, massive MS-screening for the selection of Hepatitis C virus IRES (HCV IRES) ligands identified a 2-aminobenzimidazole-containing compound. Further SAR studies conducted on 2-aminobenzimidazoles originated Isis-11, which inhibited HCV replication with a submicromolar EC50. Isis-11 exhibited a micromolar affinity against subdomain Ila of hepatitis C virus IRES (HCV IRES), an essential motif for the proper binding of the IRES to the ribosome. Structural studies showed that subdomain Ila contains a highly conserved 5-nucleotide bulge to which Isis-11 and related compounds can bind to promote a conformational switch that ultimately leads to IRES function inhibition. Foot-and-mouth disease virus (FMDV) is a picornavirus whose translation is also driven by the IRES element present at the 5'-UTR of RNA. Although HCV and FMDV IRES differ significantly in nucleotide sequences and structure, the similarities between both IRESs led us to hypothesize that 2-aminobenzimidazole derivatives could also act as FMDV IRES binders, and lead to the inhibition of FMDV IRES-mediated translation. We describe the preparation of new Isis-11 analogues, collectively referred to as IRAB (IRES aminobenzimidazole binders), that have been shown to inhibit FMDV IRES-dependent protein synthesis and viral replication at micromolar concentracions. A series of biophysical assays, such as circular dichroism, fluorescence and microcalorimetry, have been performed to determine the binding affinity of these ligands for segments of FMDV IRES. For comparison purposes, the same compounds have been also evaluated as HCV IRES ligands. In both cases, affinities in the micromolar and submicromolar range have been determined. SHAPE (Selective 2'-Hydroxyl Acylation analyzed by Primer Extension) analysis and hydroxyl radical footprinting have been also carried out to characterize the binding of IRAB analogues to FMDV IRES.

▼ This research was developed because of the need to respond to a problem present in the classroom when teaching literature to children between 9 and 15 years. It was developed in the school environment near to Bogota, Colombia, where the researcher teacher has been working over 10 years through follow-ups and observations to socio-economically vulnerable groups mostly coursing between fifth and ninth grade in high school. From the initial doctoral studies in Barcelona focused on the line of literature and audiovisual an exploratory process started to analyze how the existing classroom practices were carried out in both an elementary school in Barcelona and the Colombian school contexts, all this using the participating and non-participating interview and observation qualitative tools as well as the sporadic observation of other teaching contexts by the researcher teacher, thus supporting the formulation of a didactic and exploratory work. The objective of this research was to unravel the functioning of the literary fictional language of high school children to propose an educational model which lets the teachers to better understand the children`s expectations, experiences and performance, thus encouraging the development of their communication skills. From this perspective and work horizon, there is a need to recognize a very complex learning individual with some subjective perspectives that affect his/ her learning process. For that reason, the psychology, psychiatry, philosophy, pedagogy, literary stylistics and audiovisual theoretical sources were used to support the research. Later on an experiential job was developed where the theoretical contributions were joined to specific activities in a very diverse and troublesome context: a continuous classroom - laboratory practice for three to four years with the same groups to observe the subjective factors and psychological processes underlying from proposed activities of texts` reception and production. From that experiential work a fictional literary fictional structure was modeled in children with specific mechanisms and through the application of a flexible and systemic teaching model. The rationale of the results allowed finding variables and content that affected this evolutionary and cumulative process on the observations of the behavior of the user child. The structure of the document reflects these great moments. In the first stage the circumstances, reasons and the approach that guided this work are showed; later, the second stage presents the theoretical framework and references the research and pedagogical proposal were worked with. In the third stage, the diagnostic exploration, the development of experiential work and expected results found are showed. In the scope of the experiential work which covers most of the document, it is important to note that the development of some of the implemented learning experiences are explained, in order of complexity, gender, literary… Advisors/Committee Members: false (authoremailshow), Bordons, Glòria (director), false (authorsendemail).

▼ This research focuses on the evolution of the ideas that doctors had in Catalonia, during the XIX Century and the first half of the XX. To write this study, many texts, publications, memories and Medical academy access speeches have been analysed, as well as Records of the First International Tuberculosis Congress in Barcelona, monographies, medical magazines and single texts referring to tuberculosis, dated between 1832 and 1950 From the mid XIX century to the first half of XX century, tuberculosis was the infectious disease with the highest mortality rate in Catalonia. The concentration of the people in the city, coming from rural areas in the beginning of the industrialisation, the bad social conditions that they found, the overcrowding in the deficient houses, the unsanitary factories, the long working hours; all these facts contributed to the expansion of the disease, and the annual mortality rate reached to 50 deaths per 10.000 people The purpose of the study is to know the ideas that doctors had about the clinical manifestation of the disease, Koch’s bacillus, the different ways of transmission, the chances of infection and the effectiveness of the many treatments applied. During the studied period in this thesis, none treatment had been capable to cure the disease. Since the 20’s, with the pneumothorax, some people were cured with morbid cavity, but its indications were limited. Sanatorium care was an indirect and nonspecific measure that improved the result when including the collapsoterapy, but the effectiveness of the sanatorium was low and the cost supposed the ruin for the families. The serums, vaccines, tuberculin, gold salts, thiosulfate, did not have other utility than helping to keep hope. People with tuberculosis were hospitalised in common rooms with traumatized and operated people, and all them together with those with typhus, measles and cirrhosis. In 1910, the first room for people with tuberculosis was built in Hospital Clinic, and in that year it was also built the first sanatorium in Catalonia, followed by more, but the total number of beds was way lower that the number of patients. Then, the tuberculosis maintained a high mortality rate until the development of the chemotherapy that allowed the cure of practically the totality of the cases, when applied correctly.

▼ The main purpose of this PhD thesis is the thorough study of the chromatographic retention in RP-HPLC. In order to achieve this goal, the contributions to chromatographic retention from both the stationary and the mobile phase have been studied, as well as some of the most relevant physicochemical parameters involved in the elution process. To study the stationary phase, a detailed characterization of chromatographic columns, based on the van Deemter equation, has been performed. In it, the different terms in this equation (eddy dispersion, diffusion and mass transfer) have been assessed individually and their contribution to HPLC band broadening has been evaluated. In this sense this thesis provides an Excel spreadsheet that works as a tool able to characterize stationary phases in a systematic and efficient way. In order to address the chromatographic retention itself several prediction models have been proposed, models that are able to successfully predict the retention in gradient mode of ionizable analytes, both acids and bases. The models have been tested using a selected set of compounds, which includes some drugs with complex structures, under a large variety of experimental conditions such as different mobile phase pH values, different gradient patterns and two different organic modifiers. As an important part to the development of these predicting models, the dependence of several physicochemical parameters (such as the mobile phase pH or the analyte pKa) with the composition of the mobile phase (fraction of organic modifier) has been thoroughly studied. Additionally, this thesis also proposes an optimization to the well-known shake flask method, the reference method for the determination of drug lipophilicity (both log P and log D parameters). The two key improvements of the suggested optimization are using a low amount of drug and increasing the lipophilicity range where the shake-flask method could be applied, aspects that make the method more suitable for the new needs of the pharmaceutical industry, since companies synthesize their drug candidates, which may have a large variety of lipophilicity values, in low quantities.

▼ The purpose of this dissertation is to understand successful educational careers among young people from immigrant families at post-compulsory secondary education (hereinafter PO) under an analytical framework focusing on schools and the relational universe of students –specifically with institutional agents. The definition of institutional agents from Stanton-Salazar (1997, 2011) is adopted, so that from the finding of a considerable part of young people from immigrant families coming and attending the PO, the research explores how schools and institutional agents –peers, counsellors, teachers, etc.– encourage their stay on at school and contribute to offset the reproduction of social inequalities –caused by differences of origin, gender, social class… and, in general, by the ability of these students to fit into the school model. In particular, this work is concerned with how schools and their actors convey various forms of support that students from immigrant families use to build successful educational careers. This dissertation makes a contribution at a qualitative level on the schooling and understanding of the social and relational nature of successful educational processes in PO. It is a mixed methods sequential explanatory research of two phases (quan → QUAL) from which several cases of young people from immigrant families have been investigated. They are all students from three urban public secondary centres from the province of Barcelona who reached the last year of PO and had opportunities to continue studying. The analysis was carried out taking into account different perspectives: an institutional one –the intention which led to the study of the schools participating in the study–; an individual one –which led to the monitoring of the educational paths of these youth from the last year of compulsory secondary education (4th year of ESO) to the final year of PO–; and, a relational one –the aim of which was to discover how institutional agents and, particularly, teachers had influenced the construction of their “successful educational careers”. The dissertation is divided into three main sections. The first one is comprised by two chapters focused on the theoretical approaches and factors most used to analyse the educational careers of young people from immigrant families; and, the theories of social capital, social support, as well as the literature about school-based relationships. The second section describes the design and methodology used to address the purpose that guides this work. The last section focuses on the results and conclusions of the research. Chapter 4 discusses scenarios where young people attend school and allows the reader to understand how they influence or encourage capital formation and the shaping of successful educational careers. Chapter 5 focuses on the study of the development of their educational careers in PO. Chapter 6 is aimed at analysing the social and educational relationships of youth with institutional agents and, specifically, to understand how to promote… Advisors/Committee Members: false (authoremailshow), Marín Gracia, Ma.

▼ This work aims to analytically understand the impact of two diametric opposite environments on protein structure and dynamics and compared them to the most common solvent on earth: water. The first environment is a popular denaturing solution (urea 8M), which has served for years in protein-science laboratories to investigate protein stability; still many open questions regarding its mechanism of action remained unclear. The second environment instead moves towards a more physiological representation of proteins. The cell interior, in fact, is a crowded solution highly populated prevalently by proteins, but studies on protein structure and dynamics have lead so far to confusing or even opposite observations. The lack of a consensus view in both phenomena possibly derives from the bias of the system under study. This work is an attempt of a comparative study using the most general systems: a diverse spectrum of proteins folds, different stages along the reaction path (early stages or end-point) and/or different protein force-fields. Our main objective was to derive common pattern and general rules valid at proteome level, focusing on three major aspects of proteins: the structure, the dynamic and the interactions with the solvent molecules. Molecular dynamics simulation appeared then as the most suitable tool because of its ability to i) analyze proteins at broad range of resolutions; ii) access the direct time-resolved dynamic of the system and iii) dissect the specific interactions that arise in the new settings. Specifically, the case of urea-induced unfolding needs a system for which is possible to clearly identify folded and unfolded state – globular proteins are then the most suitable ones. We extracted general rules on the folded/unfolded transition by studying independently the two end-points of folded/unfolded reaction. We simulated the urea-induced unfolded state of a model protein, ubiquitin to understand the energetics stabilizing unfolded structures in urea. We found that the unfolded ubiquitin in 8M urea is fully extend and flexible and capturing efficiently urea molecules to the first solvation shell. Dispersion, rather than electrostatic, appear the main energetic contribution to explain the stabilization of the unfolded state. We then simulated the early stages of urea-induced unfolding on a large dataset of folded proteins, which represent the major folds of globular proteins, aiming also to investigate the kinetic role of urea in triggering the protein unfolding. We found that partially unfolded proteins expose the apolar residues buried in the protein interior, mainly via cavitation. Similar to the unfolded state, it is the dispersion interactions that drive urea accumulation in the solvation shell but here urea molecules take advantage of microscopic unfolding events to penetrate the protein interior. Macromolecular crowding instead is a phenomenon that universally affects all the proteins. We simulated a system that included as crowding agents proteins with different… Advisors/Committee Members: Universitat de Barcelona.

▼ Los habitantes del bentos antártico combaten la depredación, la competencia y el recubrimiento desarrollando mecanismos como la defensa química. Ésta estrategia está particularmente extendida entre organismos sésiles y organismos de cuerpo blando. Las defensas repelentes contra depredadores han de considerarse junto con la calidad nutricional, pues las dietas muy energéticas enmascaran la repelencia. La producción de metabolitos secundarios defensivos es costosa. Por ello, la Teoría de Defensa Optimizada (ODT) prevé que han de localizarse en las regiones corporales más valiosas o expuestas. En las comunidades antárticas los principales depredadores son las estrellas de mar y se postula la concentración de defensas en áreas superficiales en las presas. Pero también influyen las poblaciones de anfípodos asociados a los biosustratos, obteniendo en ellos refugio y fuente de alimentación. Esta tesis se centra en las defensas químicas de tres grupos relevantes del bentos antártico relativamente poco estudiados: esponjas hexactinélidas, corales blandos y ascidias coloniales. Se seleccionaron dos depredadores simpátricos, la estrella Odontaster validus y, por primera vez, fue utilizado el anfípodo Cheirimedon femoratus. Diseñamos un nuevo protocolo con numerosas ventajas metodológicas además de un gran potencial discriminatorio, y observamos que en 31 especies hubo mayor repelencia hacia el anfípodo que hacia la estrella, sobretodo en algas y esponjas, que podrían representar potenciales huéspedes-presa. A partir de aquí estudiamos muestras de los tres grupos seleccionados. En hexactinélidas, las defensas químicas son más débiles y derivadas del metabolismo primario, pero compensadas con un bajo valor nutricional. Algunos glucoesfingolípidos, podrían tener valor quimiotaxonómico como marcadores de la familia Rossellidae. En corales blandos existen metabolitos de defensa primarios y secundarios operando sinérgicamente, y probablemente forman parte del mucus superficial. En ascidias coloniales, los metabolitos defensivos son secundarios y muy potentes; además, en algunas especies éstos tienden a acumularse en tejidos internos, presumiblemente para producir larvas protegidas químicamente. Las ascidias mostraron poca actividad antibacteriana, pero algunos corales exhibieron respuestas inhibitorias. Esta Tesis proporciona la estructura, distribución y posible origen de los metabolitos responsables de las actividades defensivas en tres grupos relevantes de invertebrados antárticos.

▼ El trastorn bipolar és una malaltia altament discapacitant i que té un gran impacte en la vida dels pacients. L’any 2007, el Programa de Trastorn Bipolar de l’Hospital Clínic juntament amb la col•laboració d’altres centres internacionals, va crear una escala anomenada Functioning Assessment Short Test (FAST). Aquest instrument va surgir com a resposta a la necessitat que existia, tant en la pràctica clínica com en la recerca, d’una escala clínica que avalués el funcionament psicosocial dels pacients amb trastorn bipolar. Existeixen moltes escales per mesurar el funcionament psicosocial en les poblacions psiquiàtriques però cap d’elles és específica pel trastorn bipolar. A més la utilització de diferents instruments de mesura i paràmetres de discapacitat al llarg de la literatura fan difícil la comparació entre estudis. A més, la FAST com a escala de mesura quantitativa del funcionament psicosocial té molts avantatges respecte les que s’han utilitzat fins al moment: a) està dissenyada per experts en trastorn bipolar; per tant, els ítems que s’exploren reflecteixen realment les àrees on els pacients presenten més dificultats; b) l’avaluació és clínica, per tant no només es basa en les respostes del pacient sinó també es complementa la información amb altres fonts (curs clínic, avaluació del psiquiatre, informació dels familiars...). D’aquesta manera es superen moltes fonts de biaix típiques dels instruments d’autoavaluació, com per exemple l’estat d’ànim concomitant a l’avaluació que pot afectar positiva o negativament les respostes que dóna el pacient; c) finalment, una altra avantatge és la facilitat i rapidesa en la seva aplicació que la fa idònia per ser utilitzada tant en context de recerca com en la pràctica clínica diària. Amb la validació de la FAST, l’any 2007 , coincidint amb la meva incorporació a l’equip, es va obrir un nou horitzó per explorar el funcionament en el trastorn bipolar amb aquesta nova escala i respondre preguntes que fins ara no quedaven clares en la literatura. Així doncs, el primer pas va ser vincular-me en un estudi que ja estava iniciat, on s’avaluava el funcionament dels pacients amb trastorn bipolar en els tres estats diferents de la malaltia: eutímia, depressió i (hipo)mania en comparació amb un grup de controls sans. En aquest estudi, es va comprovar que la simptomatologia depressiva era més discapacitant que la maníaca però també es va observar que els pacients eutímics presentaven dificultats en el funcionament psicosocial. Amb el segon estudi (es va comparar una mostra de pacients eutímics dividits en funció de la tipologia diagnòstica (subtipus I vs. subtipus II) ja que revisant la literatura no quedava clar fins a quin punt aquest factor podria influenciar el funcionament psicosocial dels pacients eutímics. Finalment i aprofitant que l’escala FAST permet avaluar tant el funcionament global com també l’estudi de dominis específics del funcionament psicosocial, es va portar a terme un tercer estudi per tal d’analitzar quines variables clíniques i neurocognitives… Advisors/Committee Members: false (authoremailshow), Vieta i Pascual, Eduard, 1963- (director), Martínez-Arán, Anabel, 1971- (director), false (authorsendemail).

▼ Malaria has a high toll on the lives of infants and children under the age of five in endemic areas. Control, and more recently, elimination agendas consist on implementing several measures simultaneously, including vector control, vaccines and drugs. The current Millenium Development Goals aim at reducing malaria mortality and morbidity in the two most vulnerable groups: pregnant women and children. Intermittent Preventive Treatment in Infants with Sulphadoxine‐Pyrimethamine (IPTi-SP) delivered through routine EPI vaccination programs has shown to be efficacious in different transmission settings and the WHO has recently recommended its implementation as a malaria control tool. However, one of the main concerns has been the potential impairment of acquisition of naturally acquired immunity, and this could be a concern regarding IPTi. This thesis reports on a series of studies conducted in a malaria endemic area of Manhiça, Mozambique, to assess the impact of IPTi‐SP on the development of immune responses to the Plasmodium falciparum parasite. In this work, we measured antibody and cellular immune parameters considered to be the most appropriate markers of protective immunity against malaria identified to date. The most consistent finding was that IPTi-SP does not modify the magnitude of the immune responses acquired over the first two years of age in Mozambican children. In addition, we described the factors that affect the antibody and cellular immune responses, and reported those that correlated with prospective malaria incidence. Based on the studies presented herein, we can conclude that IPTi‐SP does not interfere with immune responses that are considered major contributors to the acquisition of protective immunity to malaria in early infancy. In summary, this thesis contributes to a more complete assessment of IPTi as a control measure that will possibly be implemented in the near future in malaria endemic areas of Africa and of the world. In addition, it aims to contribute to advance the knowledge on the acquisition of natural immunity in infancy which is poorly understood. Furthermore, this information will help to understand the factors that should be taken into account when designing and deploying other control measures for this age group.

▼ 1) The treatment of a tert-butyl beta-keto ester tethered to an omega-amino monoprotected group with crotonaldehyde using LiOH as the base, furnishes domino reactions involving the consecutive formation of two C-C bonds and one C-N bond in a sequence that comprises an intermolecular Michael process, followed by intramolecular aldol and aza-Michael reactions. This general methodology for the diastereoselective synthesis of 5-oxodecahydroquinolines implies a biscyclization and the formation of three stereocontrolled stereogenic centres in a single operational step. The resulting cis-decahydroquinoline of type A (arising from the dealkoxycarbonylation reaction) allows, through thermodynamic controlled processes, access to all other relative stereochemistries, providing a set of valuable building blocks (decahydroquinolines of Type B, C, and D). 2) The asymmetric Robinson annulation / intramolecular aza-Michael reaction leading to decahydroquinolines in a single step, from an achiral and acyclic simple beta-keto ester, is not feasible using the classical reaction conditions developed by Jørgensen to synthesize cyclohexenones. After the initial organocatalyzed Michael addition, treatment with acid to promote the dealkoxycarbonylation and intramolecular aldol reaction failed, probably due to the presence of the nucleophilic nitrogen atom in the structure. In contrast, if LiOH is added after the organocatalysis step, the Robinson annulation and the following azacyclization take place in very good yield. The method has been optimized after screenings for the solvent, temperature, additives and catalysts. The resulting decahydroquinoline building block has been used in the total synthesis of the phlegmarine alkaloid lycoposerramine Z, which has been efficiently synthesized: 10 steps and 20% overall yield. 3) A potent solution for the problematic stop-and-go procedure, in which it is necessary to stop the synthesis after each operational step to carry out the work-up and purification of intermediates, is the combination of pot economy strategy and tandem reactions. Following this alternative strategy, we have developed an efficient synthesis of the alkaloid cermizine B via an uninterrupted sequence of 7 reactions, which allowed 1 gram of the natural product to be synthesized, employing 8-12 h of operational time over 10 days. 4) The scope of the strategy developed in the experimental studies carried out in the present PhD Thesis has been extended and applied to other research projects. Thus, the described methodology is not only applicable to the decahydroquinoline nucleus for the total synthesis of phlegmarine alkaloids, but can also be potentially applied to the synthesis of other members of the Lycopodium family. Furthermore, the method can also provide access to other nitrogen-containing heterocycles such as morphans or octahydroindoles with some structural changes in the starting materials (such as the number of carbon atoms in the initial beta-keto ester or the installation of the nitrogen atom in the Michael… Advisors/Committee Members: [email protected] (authoremail), false (authoremailshow), Bonjoch i Sesé, Josep (director), Bradshaw, Ben (director), false (authorsendemail).

▼ This work focuses on the remediation of emergent contaminants by using AOPs. In this way, the study has been divided in three parts: ▪ Degradation of a model compound, the pharmaceutical propranolol (PRO), at laboratory scale, by photocatalysis, photo-Fenton and direct photolysis. Photocatalysis was also studied in a solar pilot plant, to approximate to real application. ▪ Remediation of a large ECs group including pharmaceuticals, biocides/pesticides and corrosion inhibitors, found in a MWTP effluent. AOPs employed were UV, UV/H2O2, ultrasound (US) and combined US, Fenton and photo-Fenton at neutral pH. ▪ Radiation is a key parameter in photocatalytic systems. Thus, an actinometric method was studied to determine the radiation entering a photreactor with the presence of a catalyst (TiO2) in suspension. The work on PRO remediation showed that direct photolysis, photocatalysis and photo-Fenton could degrade PRO (photocatalysis: 99%, 360 min, photo-Fenton: 99%, 15 min, photolysis: 84%, 360 min). Employing direct photolysis, mineralization obtained was poor (6%, 360 min). Good mineralizations were achieved with photocatalysis (58%, 360 min) and photo-Fenton (60%, 60 min). Solar photocatalysis was also found to be an efficient method for PRO remediation. After 240 min, 81% of degradation was reached, with a mineralization of 31%. In the remediation of a ECs group found in a MWTP effluent (at nanograms per litre), the most efficient treatment was the photo-Fenton with UV at 254 nm. The average degradation after 5 min was 85% (30 mg L-1 of H2O2 + iron present in the wastewater). Influence of different parameters was studied: H2O2 initial concentration, iron concentration and type (Fe II-III), radiation source, temperature and oxygen. The study of a ECs group remediation at pilot showed that the treatment with UV (254 nm) + H2O2 + Fe (not added but present in WW) at natural pH, leaded to degradations higher tan 80% with very low residence times. The most economical treatment needed 50 mg L-1 of H2O2 and a residence time of 10 s. In the section of the radiation measurement in photocatalytic systems, it was demonstrated that the o-NB actinometry could be used to measure the involved radiation when there is TiO2 in suspension present inside the photoreactor.

▼ This Thesis aims to characterize the formation and deformational and kinematic evolution of the Altomira and Loranca fold-and-thrust belts (Altomira Range and Loranca basin, SW Iberian Chain, Central Spain) and the structural configuration and evaluation as a potential reservoir for CO2 sequestration of the Puerta-Pareja anticline, located in the northern sector of the Loranca basin. Several methods were integrated in order to overcome the limitations of every single study in the studied area and to achieve the proposed objetives. Thus, at regional scale, a E-W cross-section and its 2D restoration, an analysis of the anisotropy of the magnetic susceptibility (AMS) and a paleomagnetic analysis were performed and, focused on the Puerta-Pareja anticline, its 3D reconstruction and restoration and analysis of its fracturation were conducted. The results of the AMS analysis show a general E-W layer-parallel shortening orientation during and shortly prior to the formation of Altomira and Loranca fold-and-thrust belts. Paleomagnetic data from Middle Eocene to Lower Miocene rocks reveal the absence of vertical-axis rotations in the central sector of Loranca-Altomira where structures are oriented N-S, and up to 17º of clockwise and 21º of counter-clockwise vertical-axis rotations in the northern and southern sectors, respectively. The integration of paleomagnetic data with previous structural data from other authors shows that the piggy-back sequence of thrusting at the southern sector was synchronous to the counter-clockwise rotation during the Oligocene, whereas at the northern sector structures formed in a break-back sequence and experienced a clockwise rotation during Miocene. The Puerta-Pareja anticline is a NNE-SSW fault-propagation fold associated to the Pareja thrust and initially nucleated as a detachment fold. At its northern part, the La Puerta thrust cuts its front limb defining a steep-limb breakthrough configuration. Three minor thrusts cut its back limb: the Viana (NNE-SSW), the Villaescusa (NW-SE) and the Peralveche (NW-SE) thrusts. All of these thrusts detached on the Keuper facies following a break back sequence. The 3D reconstruction and restoration of this anticline shows the absence of any basement structure suitable for sequestering CO2 underneath. The analysis of the chronological and geometrical relationships between the fracture pattern (mainly transverse and longitudinal fractures) and the vertical-axis rotation at the Puerta-Pareja area reveals that the initial orientation of the Puerta-Pareja anticline was N-S, perpendicular to the E-W regional shortening direction. Subsequently, local differences in the amount of the clockwise vertical-axis rotation occurred generated the present variability of axial orientations.

▼ Gene expression is a complex and highly regulated process. Most of the regulation is controlled by short DNA sequences that can be bound by some proteins called transcription factors (TF). Binding to these sites, the transcription factors, can start the transcription of mRNA, stop it, or just control the amount of mRNA produced. The DNA binding sites of these transcription factors have some specific characteristics: (1) They are short sequences (2) They can be located anywhere in the genome and (3) they are degenerated, which means that some mutations in the binding site sequence do not alter its functionality. These characteristics made impossible to look for a specific sequences in a specific region and, create the need to model the binding sites in order to detect them. Due to the importance of gene expression in the study of cell differentiation and its implication in some genetic diseases, many computational models and experimental processes to model binding site motifs and then find them into a genome have appeared. The computational models can be divided into two main groups: motif discovery methods which try to find binding sites within a set of co-regulated sequences without previous knowledge and motif search methods which use previous known sites to create a model and then try to locate binding sequences fitting this model. Most of the algorithms for binding site detection (both discovery and search) are based on Position weight matrices (PWM), which are matrices of frequencies of each nucleotide in each position, and assume that positions are independent. Some others take into account interdependences, but they need many sequences to be trained and high computational times. The focus of this thesis is to use the conversion from symbolical to numerical DNA and the previous knowledge of binding site sequences in order to construct models for DNA motifs. In this context, known multivariate signal processing techniques can be the ideal tools to construct models which can take into account interdependences without needing a large number of sequences or a high computational time. To characterize the transcriptions factors, the relationships TF-protein were studied, showing that most transcription factors regulate the expression of 5-10 genes and at the same time most proteins are regulated by more than 1 TF. The study of interdependences between positions showed that more than 90% of the binding sites have significant interdependences, but that the percentage of interdependences is not enough to classify TF according to structure. The conversion of DNA motif matrices into numerical matrices allows the use ofl Component Analysis (PCA) to model the binding sites which captures the information of the interdependences into the covariance, a second order statistics. Using the hypothesis that the binding sites will fit better to the PCA model than genomic, sequences, the Q-residuals can be used to detect binding sites within the genome. When compared to PWM the Q-residuals detector performs as least as… Advisors/Committee Members: false (authoremailshow), Marco Colás, Santiago (director), Perera Lluna, Alexandre (director), false (authorsendemail).

▼ Persistent organic pollutants (POPs) are a well-known group of contaminants that have in common some characteristics. As its name indicates, they can remain in the environment for long periods of time, they are stable and do not degrade easily. Furthermore, they are toxic and because of their physical and chemical properties they can be distributed throughout the planet reaching remote places far away from pollution sources. In addition, they are lipophilic and with great capacity to bioaccumulate inside the organisms so they are biomagnified along food webs. The production of organochlorine compounds during the last century by the chlor-alkali plant located at Flix (South West Catalonia) has generated an accumulation of polluted muds inside the water reservoir from this locality. Concerning the concentrations of organic pollutants, so far the organisms living in the last stretch of the Ebro River have only been considered partially. This thesis includes a complete study of the distribution and accumulation of these compounds in fluvial food webs starting from the lower trophic levels and including main predators. Different organochlorine compounds have been analyzed in a wide range of biotic and non-biotic matrices: chlorobenzenes (PeCB and HCB), polychlorobiphenyls (PCBs), hexachlorocyclohexanes (HCHs), dichlorodiphenyltrichloroethane (DDT) and its metabolites, as well as the polychlorostyrenes (PCSs). To complement this research, the presence of these compounds has been assessed in sites located far away from main pollution sources. To achieve this, samples from the last stretch of the Ebro River have been analysed in order to assess if there were differences in concentrations in comparison to samples from the Flix water reservoir, differences in distribution patterns of POPs, or differences at the biomagnification processes of these compounds. Firstly it studies concentrations of POPs and the relationships between lower trophic levels from the Flix water reservoir. Secondly it evaluates levels of contaminants from fish inside the Flix water reservoir and downstream. Third, it determines the effect that POPs have at higher trophic levels from fluvial food webs: birds. Finally, it integrates all the information related to the biomagnification of pollutants along the food web within the Flix water reservoir.

▼ Di-n-butyl ether (DNBE) is considered a very attractive oxygenate compound to reformulate diesel fuel. The research work performed along this thesis has clearly proven that sulfonic P(S-DVB) ion exchange resins are suitable catalysts for the synthesis of DNBE from the liquid phase dehydration of 1-butanol at the temperature range of 140-190 °C. A catalyst screening of acidic P(S-DVB) ion exchange resins showed that resins activity is enhanced with high acid capacities and with polymer matrices that are able to swell moderately allowing 1-butanol ready access to the active sites but without resulting in very large distance between the active centers. The resin Amberlyst 36 (oversulfonated, medium values of %DVB) proved to be the most active catalysts tested. However, in an industrial process a high selectivity to DNBE is extremely desirable from an environmental and economic standpoint, and resins that present a more elastic polymer matrix and higher ability to swell (gel type resins and Amberlyst 70) are the ones that present higher selectivities. Among all the tested resins, Amberlyst 70 was selected as the most suitable catalyst for industrial use given its excellent property balance: satisfactory activity, high selectivity to DNBE and thermal stability up to 463 K. The relatively large value found for the thermodynamic equilibrium constant of DNBE formation and the fact that the formation of the secondary product 1-butene was extremely slow assure high conversion levels in an industrial etherification process. DNBE formation proved to be a slightly exothermic reaction, almost athermic, whereas 1-butene formation was found to be an endothermic reaction. A comprehensive kinetic analysis enlightened that the reaction rate to form DNBE on Amberlyst 70 is highly influenced by the temperature and the presence of water. Two kinetic models that are able to predict the reaction rates of DNBE formation were identified. One of them stems from a Langmuir-Hinshelwood-Hougen-Watson (LHHW) formalism in which two adsorbed molecules of 1-butanol react to yield ether and water, being the reversible surface reaction the rate limiting step. The other one stems from a mechanism in which the rate limiting step is the desorption of water and where the adsorption of DNBE is negligible. Both models present several characteristics in common: in both water inhibition effect is correctly represented by a correction factor derived from a Freundlich adsorption isotherm; the number of free active sites is found to be negligible compared to the occupied ones; both present similar values of apparent activation energies (122 ± 2 kJ/mol). The study of the influence of typical 1-butanol impurities (isobutanol or ethanol and acetone, depending on the production process) demonstrated that isobutanol enhances the formation of branched ethers whereas ethanol leads to the formation of ethyl butyl ether and di- ethyl ether and acetone hardly reacts. In the second part of this thesis, it was demonstrated the suitability of molecular dynamics… Advisors/Committee Members: false (authoremailshow), Iborra Urios, Montserrat (director), Bringué Tomàs, Roger (director), Iborra Urios, Montserrat (tutor), false (authorsendemail).

▼ Hyperspectral images are unique instrumental measurements that contain chemical (spectral) information and detailed knowledge of the distribution of the sample constituents on the sample surface scanned. This thesis is mainly oriented to know in depth the nature of this instrumental measurement in order to design and adapt specific chemometric tools that help in the proposal of general protocols for the interpretation of hyperspectral images according to the spectroscopic technique used and the chemical problem of interest. Particularly, much work has been focused on the study of the potential of multivariate curve resolution-alternating least squares, MCR-ALS, for the analysis of hyperspectral images. This algorithm provides distribution maps and pure spectra for the image constituents from the sole information contained in the raw measurement. Within this framework, individual analysis of images and image multiset analysis on data structures formed by images collected with the same technique or by images coming from different spectroscopic platforms have been explored. From the study of Raman and IR hyperspectral images linked to different chemical problem typologies, data analysis protocols have been proposed that include preprocessing of original data, recovery of distribution maps and pure spectra of image constituents and postprocessing of resolved maps and pure spectra to obtain further information. Resolved distribution maps and pure spectra provide diverse information, such as identification, quantification and heterogeneity characterization of the image constituents or the global and local description of a process. The use of resolved distribution maps has proven to be an excellent starting point for other kinds of analysis, such as image segmentation or super-resolution algorithms, oriented to improve the spatial resolution of experimental hyperspectral images. Combined multiset resolution and segmentation analysis has been shown to be very useful for the differentiation of populations of biological tissues with different pathological conditions. Finally, a strategy for data fusion of hyperspectral images from different spectroscopic platforms and different spatial resolution has been proposed. This approach uses a new variant of MCR-ALS for incomplete multiset structures that takes advantage of the complementary information provided by the different spectroscopic techniques without losing spatial resolution.

▼ The synthesis and characterization of Pt(Cu) and Pt−Ru(Cu) nanoparticles on Vulcan XC72R carbon support has been studied in this thesis for their possible application as anode catalysts in proton exchange membrane fuel cells (PEMFC) and direct methanol fuel cells (DMFC). They were obtained on the glassy carbon (GC) of the rotating disk electrode (RDE) in the following sequence: i) Cu electrodeposition; ii) galvanic 2− ; and iii exchange with PtCl6 ) spontaneous deposition of Ru species. The Pt(Cu)/C and the the Pt−Ru(Cu)/C catalysts were obtained after the steps ii and iii, respectively. The different variables studied in the synthesis process were the oxidation potential of carbon, the electrodeposition potential of Cu, the Cu load on carbon, the times for the galvanic exchange with Pt and for the spontaneous deposition of the Ru species, and the stirring rate, commanded through the rotation rate of the RDE. The catalysts were electrochemically tested by chronoamperometry, linear sweep voltammetry and cyclic voltammetry, thus allowing obtaining the current efficiency for the Cu electrodeposition, the electrochemical active area (ECSA), and the characteristic potentials for the CO and the methanol oxidation. The best catalysts were studied by means of transmission electron microscopy (TEM), high resolution TEM (HRTEM), energy-dispersive spectroscopy (EDS), electron diffraction, fast Fourier transform (FFT), and X-ray photoelectron spectroscopy (XPS). The application of these techniques allowed optimizing the preparation conditions of the catalysts when applied to the CO and methanol oxidation, with nanoparticle size about 3−4 nm. The oxidation potentials of CO and methanol were about 0.05−0.1 V lower than those measured on Pt/C and Pt−Ru/C, thus indicating their higher activity, due to the effect of the Cu core on the structure of the Pt shell. In addition, a Pt economy of about 40−50% was achieved when using the synthesized Pt(Cu)/C and Pt−Ru(Cu)/C catalysts.

▼ The present Doctoral Thesis describes our efforts towards the Total Synthesis of Amphidinolide B2, a novel macrolide with potent cytotoxicity against lymphoma murine cells and humane carcinoma cells. It is a 26-membered ring macrolactone, with an allylic epoxide, four doble bonds and 9 stereogenic centres. However, the absolute configuration is still unknown as Carter and co-worker sinthetised the proposed structure and observed that the spectroscopic data were not in agreement with those reported by Shimizu. They propose a new structure for Amphidinolide B2, where the two alcohols in C16 and C18 have a syn relative configuration. Our retrosynthesic analysis was based in four main disconnections that lead to four principal fragments. The synthesis of Fragment I has been optimized using a methyl ketone asymmetric allylation of ketones developed by Schaus. In this manner, the synthesis of the fragment could be achieved in 3 steps and 32% overall yield. Fragment II was envisage via an olefination reaction of lactol 1.9. However, this reaction was not trivial and an exhaustive study was carried out. Finally, using Wittig olefination reaction with 0.9 equivalents of ylide or 2.0 equivalents of trifluoroethanol, the product could be obtained. Negishi reaction has also been studied for the Csp3–Csp2 coupling. After several optimizations, we have been able to synthesize Western Fragment with this protocol. Finally, Jørgensen’s catalytic asymmetric epoxidation allowed us to the formation of the α,β-epoxy aldehyde. Taking advantage of the Negishi reaction study performed bellow, we decided to focus our attention in the challenging C15–C16 bond formation of Palmerolide A, a melanoma-inhibiting macrolide. After some studies changing the protecting group, we obtained the coupling product in 78% yield. Fragment IV is the simplest of all. The synthesis starts from γ-butirolactone and sulfone 6.1 is obtained in 4 steps and 53%. This compound was used for the Julia–Kocienski olefination obtaining 6.3 in moderate yield. Unfortunately, we haven’t had enough time to continue with the synthesis, which implies a saponification, sterification of Fragment II, ring-closing metathesis to form the macrolactone and the final directed oxi-Michael adition to obtain the C18 stereogenic center.
