Streszczenie:

Staphylococcus aureus is an important human pathogen. The emergence of multiple antibiotic resistant bacteria and lack of new antibiotics has highlighted the need for better understanding of staphylococcal physiology, molecular biology and virulence. In S. aureus the agr quorum sensing (QS) system is a global regulator of virulence. In the agr system an autoinducing peptide (AIP) activates the histidine protein kinase (HPK), AgrC, leading to a switch from the production of colonization factors to exotoxins. The S. aureus agr system has diverged such that there are four different agr groups, each with a distinct AIP capable of activating its cognate AgrC but inhibiting the AgrC of the other groups. To investigate the molecular basis for the recognition of AIPs by AgrC, transmembrane topology modelling together with site-specific mutagenesis were used. The transmembrane topology of AgrC was predicted to consist of six transmembrane helices (TMHs) and three extracellular loops with both the N- and C-terminals on the cytoplasmic side. Since AIP-1 and AIP-4 differ by a single amino acid residue, the S. aureus AgrC1 and AgrC4 proteins were compared to identify extracellular amino acids likely to be involved in AIP recognition. Site-specific mutagenesis was used to exchange the key AgrC1 and AgrC4 amino acid residues in extracellular loops 1 and 2. The response of these AgrC mutants was evaluated using a novel bioluminescent AIP reporter. The data obtained showed that differential recognition of AIP-1 and AIP-4 depend primarily on three amino acid residues in loop 2, but that loop 1 plays an essential for activation but not for inhibition of AgrC. The data obtained also revealed that a single mutation in the AgrC1 loop2 results in conversion of (ala5)AIP-1 from a potent antagonist to an activator, essentially forcing the evolution of a fifth agr group. Attempts to identify AgrC in the cytoplasmic membrane using Western blotting failed, but data obtained using an N-terminal gfp tag showed that AgrC is evenly distributed through out the membrane. Since the processing of AgrD by AgrB to generate an AIP requires at least 3 steps - two endopeptidase steps and the formation of a thiolactone bond to form the macrocycle, it is likely that other proteins are involved in the processing of AgrD and export of the AIP. To identify potential AgrB partners, yeast two hybrid assay was employed which revealed a potential role for the putative ABC transporter Rlp in the processing and/or secretion of AIP. In summary, the data presented define the key amino acid residues involved in AIP/AgrC interactions and imply a role for proteins such as Rlp in AIP synthesis and export.

Streszczenie:

The accessory gene regulator (agr) quorum-sensing system is one of the major regulators of virulence factor production in the pathogen Staphylococcus aureus. Activation of the system depends on the production and sensing of a cyclic peptide signal called the autoinducing peptide (AIP). The biosynthesis of AIP depends on the coordinated action of the AgrB integral membrane endopeptidase and SpsB signal peptidase to process the peptide precursor AgrD into the final signal structure. The primary goal of this dissertation was to gain further insight on the role of AgrD and AgrB in the AIP biosynthesis mechanism. Studies in Chapter II were undertaken to better understand the role of AgrD domains in AgrB-mediated processing. A series of truncation and site-directed mutagenesis studies identified key residues in the AgrD C-terminus that were essential for AgrB processing and AIP production. In parallel, genetic manipulation of the N-terminal leader and AIP-encoding sequence revealed a role for these segments in AIP processing. For the first time, a complex of AgrD covalently linked to AgrB was identified, supporting proposals that this intermediate is an important precursor to AIP production. In Chapter III structure-function studies were performed on AgrB to gain further insight into the AIP biosynthetic mechanism. Initially, the agrBD genes were subjected to random mutagenesis and screened for deficiencies in AIP production. Single-site mutations at 20 different residues within AgrB and another 14 in AgrD were isolated. Interestingly, new mutations in the AgrD N-terminal leader were identified that affect AIP biosynthesis at different steps. In AgrB, most of the mutations blocked peptidase activity, but charge alterations to the K129-K131 region were defective in a later pathway step, separating the peptidase function from AIP ring formation and transport. To localize the AgrB mutations, we reevaluated the membrane topology using the substituted cysteine accessibility method. Our new model predicts four transmembrane helices and a reentrant loop, with both termini located outside of the cell. Finally, co-immunoprecipitation studies indicate that AgrB forms oligomeric structures within the membrane. Taken together, these findings provide a better understanding of the functional role of specific AgrD and AgrB regions in AIP biosynthesis.

Streszczenie:

I sistemi pastorali possono fornire una vasta gamma di servizi ecosistemici che vengono definiti dal Millennium Ecosystem Assessment come “i benefici che le persone ottengono dagli ecosistemi” e vengono classificati in quattro gruppi: i) supporto (necessari per la produzione di tutti gli altri servizi ecosistemici; es. produzione primaria), ii) approvvigionamento (prodotti forniti dagli ecosistemi; es. cibo, acqua), iii) regolazione (benefici ottenuti dalla regolazione dei processi ecosistemici; es. regolazione del clima) e iv) valori culturali (benefici non materiali che la popolazione ottiene dagli ecosistemi; es. esperienze estetiche). L’obiettivo principale della tesi è stato quello di utilizzare le analisi di alcuni dei più importanti servizi ecosistemici forniti dai sistemi agro-pastorali estensivi della regione Marche (Italia centrale), a supporto dei processi di co-progettazione di misure agro-climatico ambientali. Nel capitolo iniziale, attraverso un lavoro di review della letteratura scientifica, la tesi esamina le tendenze e gli approcci utilizzati nell’analisi di alcuni servizi ecosistemici forniti dai sistemi pastorali alla luce dei principi del Millennium Ecosystem Assessment. Successivamente, la tesi si concentra principalmente sull’analisi delle emissioni di alcuni gas ad effetto serra generati da diversi sistemi colturali e diverse gestioni: (i) respirazione del suolo di una prateria montana a dominanza di Bromus erectus sottoposta a diverse intensità di utilizzazione; (ii) emissioni di N2O in un sistema medica-frumento, con e senza l’applicazione di biochar, in un’area collinare. Nell’ultimo capitolo, la tesi analizza i processi di progettazione di misure agro-ambientali per la gestione di problematiche ambientali a scala territoriale in numerosi casi di studio. L’analisi della letteratura ha rivelato una generale confusione da parte dei portatori d’interesse relativamente al concetto di servizio ecosistemico. La biodiversità viene considerata un servizio ecosistemico di per sé e la visione antropocentrica dei servizi ecosistemici non è accettata o compresa. Dalla review emerge inoltre lo scarso utilizzo di un approccio multi-settoriale nell’analisi dei servizi ecosistemici, nonché quello di un’integrazione delle diverse conoscenze. In aggiunta, i servizi ecosistemici culturali risultano scarsamente studiati, nonostante siano considerati di grande importanza per i portatori d’interesse sia locali che generali e che, insieme ad altri importanti servizi ecosistemici, potrebbero favorire l’adozione di politiche e misure agro-ambientali. Dall’analisi della prateria a dominanza di Bromus erectus, non emerge nel breve periodo un impatto significativo dell’intensità di utilizzazione sulla respirazione del suolo né sulla produzione primaria. Nel sistema medica-frumento, l’analisi delle emissioni di N2O suggerisce che: i) la lavorazione posticipata in autunno può mitigare la perdita di azoto sottoforma di N2O; ii) gli effetti dell’applicazione del biochar dovrebbero essere analizzati nel lungo periodo per verificare i possibili effetti dell’invecchiamento del biochar, anche sulla produttività della coltura. I risultati ottenuti da questa ricerca potrebbero contribuire alla condivisione di conoscenze e alla formazione di una conoscenza ibrida che, insieme al cambio di ruolo dei portatori d’interesse del sistema, sono risultati elementi chiave del processo di co-progettazione di misure agro-climatico ambientali sito specifiche, condivise e a scala territoriale.
Grazing systems can provide a wide array of ecosystem services, defined by the Millennium Ecosystem Assessment as “the benefits that people obtain from ecosystems” and classified in four main groups: i) supporting (necessary for the production of all other ecosystem services; e.g. primary production), ii) provisioning (products obtained from ecosystems; e.g. food, fresh water), iii) regulating (benefits obtained from the regulation of ecosystem processes; e.g. climate regulation) and iv) cultural (non-material benefits people obtain from ecosystems; e.g. aesthetic experiences). The thesis aims to investigate some relevant ecosystem services provided by extensive agro-pastoral systems in the territory of the Marche region (central Italy) to support the co-design process of agrienvironmental climate measures. The thesis originates from a review paper that analyses the trends and approaches used in the analysis of relevant ecosystem services provided by grazing system, according to the framework principles of the Millennium Ecosystem Assessment. In a following step, the research focuses on the analysis of the greenhouse gases emissions under different cropping systems and management options: soil respiration from a Bromus erectus-dominated grassland under different mowing intensities in the uplands and N2O emissions in a alfalfa-wheat system with biochar application in the lowlands. A final chapter analyses the design process of agri-environmental measures at landscape scale implemented in several case studies. The literature review revealed a misunderstanding concerning the concept of ecosystem services among stakeholders. The biodiversity was considered an ecosystem services per se and the anthropocentric vision of the ecosystem services was not accepted or understood, moreover a lack of a multi-sectoral approach in the analysis of ecosystem services and the integration of different knowledge emerged. Furthermore, cultural ecosystem services were poorly studied despite being considered the most relevant for local and general stakeholders and with some other relevant services, could foster agri-environmental schemes. From the analysis of the soil respiration from a Bromus erectus-dominated grassland emerged that more intensive use did not significantly impact soil respiration and primary production on the short term. The analysis of the N2O emissions in the alfalfa-wheat system suggests that: i) postponed tillage in autumn may mitigate nitrogen losses as N2O after alfalfa termination; ii) the effects of biochar application on N2O emissions and crop productivity should be analysed in a long term perspective to verify the ‘biochar aging’. The results obtained from the research could feed the hybrid knowledge, that with shift of the stakeholder role in the system are key elements for the co-design process of site specific, shared and landscape agrienvironmental measures.

Doutoramento em Arquitectura Paisagista - Instituto Superior de Agronomia
The present dissertation is focused on the study of contemporary Food Planning, an emerging area of interdisciplinary research, with greater development in Europe, U.S.A. and Canada. The limits to the approaches for the conservation of agricultural land, current at the end of the century XX, have been identified in several countries, including France, where peri-urban agricultural policies, have been implemented since the 70s. In the 90s, the experiences of collective action of local initiative by elected officials, urban residents and managers of rural areas, have helped to limit urbanisation and to the development of agricultural projects – agrourban programs. These were designed to protect the economic viability of agriculture through development programs, which in the metropolitan context take into account the specificity of the peri-urban agriculture and its potential for the development of Short Food Supply Chains (SFSCs). In this context, knowing the productive potential of a region on the basis of existing food needs is of paramount importance to policies aimed at creating Local Food Systems or Territorial Food Systems. Considering the role of Landscape Architecture in ecologically based Landscape Planning, the main objective of this thesis is to evaluate the proposal for food system relocalisation, considering production side of the food system, in the case study area – Ribatejo e Oeste. The results of the Landscape Foodshed Plans to be presented will demonstrate the potential for the relocalisation of the food system, while ensuring the sustainable use of the regional ecological basis of food security. In the context of the current debate on diets sustainability in the Global North countries, three diets will be tested with variable degrees of affluence, to take in account differences in land use

Desde el inicio, el ser humano a creado asentamientos en base a la relación que establece con el medio natural, agua, energía y suelo para poder abastecerse de alimento y sobrevivir. Hoy en día las ciudades se han planteado en base a crear asentamientos en grandes magnitudes, donde el ser humano pierde la conexión con el medio natural y principalmente con sus necesidades básicas, convirtiendo a la ciudad en un organismo altamente dependiente de combustibles fósiles para abastecer a sus habitantes y trayendo consigo problemáticas dentro de lo que hoy entendemos como calentamiento global. En este contexto nace la Comunidad Agro-Sustentable experimental en San José de Maipo, que plantea una forma de expansión urbana, considerando la producción de alimento como una oportunidad en beneficio directo de la población, dentro de las estrategias de desarrollo a nivel metropolitano. El proyecto propone un modelo de comunidad agrícola contemporánea como una forma de generar asentamientos sustentables. Se Aplicará la agricultura urbana como herramienta de organización comunitaria. Y se desarrollará una propuesta habitacional en San Jose de Maipo, que integra la autoproducción de alimentos generando una expansión y abastecimiento sustentable de la Región Metropolitana.

This current study proposal is to analyze the manifestations of the agrarian question as they project themselves in the fight for the work land in the state of Rio de Janeiro at the XXI century. The study is analytically based on the trajectories of the families of agricultural workers from the encampment Terra Prometida. Currently situated in the region called Baixada Fluminense, the encampment holds seventy-four families distributed in its two headquarters: The first one in the district of Tingu?, Nova Igua?u city and the second in the city of Duque de Caxias. That?s about the rescue of the agrarian question in the state of Rio de Janeiro, looked by the trajectory of these families. The state of Rio de Janeiro, although considered predominantly urban, possesses considerable extensions of cultivating lands, many of them idle. It also possesses an increasing number of agricultural workers who, without access to the work in the land, come increasing the mass of urban workers without any qualification, what generates some similar social problems to the ones of other Brazilian states. The observation of the agrarian question redimensioning in the current times generated some questionings that had guided the field research. How can the agrarian question that some authors more affirm not to exist in the current times, still to be reason of as many disputes and fights? Disputes these that happen also in the public space and in the private one, with the occurrence of violence, threats and murders. Could we be coexisting today with a new agrarian question or only the modernized version of a secular question? Is it possible that the agrarian question have been only updated and not disappeared ? For the agricultural workers of century XXI, what or who represents the large state in the present time? Under which forms or aspect materialize their conscience about the work land in the state of Rio de Janeiro of the recent years?
A presente disserta??o se prop?e analisar as manifesta??es da quest?o agr?ria, conforme se projetam na luta pela terra de trabalho no Estado do Rio de Janeiro do s?culo XXI. O estudo tem como base anal?tica as trajet?rias das fam?lias de trabalhadores rurais do Acampamento Terra Prometida. Atualmente situado na regi?o da Baixada Fluminense, o acampamento comporta setenta e quatro fam?lias distribu?das em suas duas sedes: A primeira no distrito de Tingu?, em Nova Igua?u e a segunda, no munic?pio de Duque de Caxias. Trata-se de resgate da quest?o agr?ria no Estado do Rio de Janeiro a partir da trajet?ria destas fam?lias. O Estado do Rio de Janeiro, apesar de considerado predominantemente urbano, possui consider?veis extens?es de terras cultiv?veis, muitas delas ociosas. Possui tamb?m um n?mero crescente de trabalhadores rurais que, sem acesso ao trabalho na terra, v?m se somando ? massa de trabalhadores urbanos sem qualquer qualifica??o, o que gera alguns problemas sociais semelhantes aos de outros estados brasileiros. Desde a d?cada de 1950, o estado ? palco de intensos conflitos pela posse da terra, entretanto, a partir do final do s?culo passado ? poss?vel perceber um redimensionamento destes conflitos, que deixaram de se travar prioritariamente nos espa?os rurais e adquiriram novas caracter?sticas. Os enfrentamentos, assim como as manifesta??es vis?veis da quest?o agr?ria, t?m agora no espa?o urbano um novo palco de conflitos. As observa??es deste redimensionamento da quest?o agr?ria nos tempos atuais geraram alguns questionamentos que nortearam a pesquisa de campo. Como a quest?o agr?ria que alguns autores afirmam n?o mais existir pode, atualmente, ainda ser motivo de tantas disputas e lutas? Disputas estas que se d?o tanto no espa?o p?blico, quanto no privado, com a ocorr?ncia de viol?ncia, amea?as e assassinatos. Estar?amos convivendo hoje com uma nova quest?o agr?ria ou apenas com a vers?o modernizada de uma quest?o secular? ? poss?vel que a quest?o agr?ria tenha apenas se atualizado e n?o desaparecido ? Para os trabalhadores rurais do s?culo XXI, o que ou quem representa o latif?ndio na atualidade? Sob que forma ou aspecto materializa-se a consci?ncia destes trabalhadores sobre a terra de trabalho no estado do Rio de Janeiro dos anos recentes?

La lingua di Una questione privata e de La vita agra, vista come costruzione culturale condizionata dal contesto, sarà l’oggetto di questo lavoro. L’accento sarà messo sulla sua capacità di andare oltre la mera definizione del dizionario e condizionare il lettore, avvicinandolo ai personaggi. In particolare, si studierà la presenza di termini nella loro lingua originale, come mezzo per permettere al lettore di trovarsi sulla stessa lunghezza d’onda dei personaggi e di avere la loro stessa percezione della realtà. Effettivamente, nei due romanzi scelti, le lingue straniere hanno un forte rilievo, che se nell’opera di Fenoglio si nota soprattutto a livello di riferimenti più o meno impliciti alla letteratura inglese, in quella di Bianciardi si coglie come vera e propria presenza di interferenze. In entrambi i casi, questa tendenza è principalmente dovuta all’esistenza di un “io traduttore”, in cui si incontrano l’io dell’autore e l’io del protagonista. Si può affermare, dunque, che l’uso di termini stranieri sia una scelta stilistica consapevole e volontaria dei due scrittori, che tra l’altro erano anche traduttori, proprio come i loro protagonisti.

Streszczenie:

No início dos anos 2000 consolidou-se o quadro de significativas alterações e ajustes nas estratégias das organizações agrícolas. Destacam-se: a consolidação das organizações, a internacionalização dos sistemas de base agrícola, a inovação presente em processos e produtos e de natureza organizacional, a introdução da variável socioambiental, e a adoção de estratégias de transparência. A cooperação pode exigir investimentos especializados, e os incentivos para a sua realização dependem de mecanismos de controle de custos de transação. Com a presença de incerteza no ambiente econômico e nas transações, a flexibilidade planejada visa eventuais ajustes em face de eventos inesperados. Arranjos institucionais complexos (leia-se, contratos) são observados como forma de responder a necessidades apontadas. Além de confiança, reputação, e mecanismos relacionais, a evolução dos mecanismos sociais por trás dos contratos de sociedade é algo a ser desenvolvido. O presente estudo propõe que as cooperativas agrícolas podem desenvolver mecanismos de governança que geram uma competência adaptativa para enfrentar eventos inesperados. O presente estudo explorou uma visão retrospectiva de estratégias adotadas por cooperativas brasileiras. Assumiu-se aqui uma nova vertente analítica da \"História de Negócios\" e suas implicações voltadas ao sistema agroindustrial. Como diretriz de método, foram seguidas as etapas de identificação das principais estratégias relatadas nos estudos de casos escolhidos, sobre cooperativas, desenvolvidos entre 1991 e 2002. Na sequência compararam-se as estratégias com as diretrizes apresentadas no capítulo teórico. Admite-se que as estratégias que implicam em maiores investimentos em ativos específicos tendem a tornarem mais rígidos os arranjos e dificultam a plasticidade, ou adaptação, das cooperativas agrícolas - onde naturalmente as mudanças ocorrem de forma mais lenta - frente a choques ou eventos externos.
The early 2000s consolidated the framework of significant changes and adjustments in the strategies of organizations working in agribusiness systems. Of note are: the consolidation of the organizations themselves, the internationalization of agricultural-based systems, the innovation in processes and products, organizational innovations, environmental variables and the adoption of transparency strategies. Cooperative efforts may require specialized investments in the form of incentives that depend on transaction cost control mechanisms. The environmental and transactional uncertainties and the need for flexibility on the part of organizations are all considered in the relevant literature. Complex institutional arrangements (contracts) are seen as a means to meet these needs. In addition to trust, reputation and business relationships, the evolution of the social mechanisms behind the contracts of society is an area of study to be further developed. Farming cooperatives are good examples how unexpected events can be addressed and strategies of adaptation can be implemented. In this study, we presented a retrospective view of the strategies adopted by Brazilian cooperatives. We adopted a new analytical \"business history\" approach to agro-based systems. When researching this work, we noticed a lack of research into the history of agribusiness. As a guideline method, we followed the steps of identifying key strategies reported in chosen case studies of cooperatives published between 1991 and 2002. Subsequently, the strategies were compared with the guidelines presented in the work. We admit that strategies based on high levels of asset specificity become more inflexible the arrangements and difficult plasticity or adaptation of the agricultural cooperatives - where changes naturally occur slowly - in face of external shocks or events

Streszczenie:

Nei moderni mercati, il cui perimetro è così vasto da aver fondato la nozione di mercato globale, circolano merci identificabili solo nel genere, e sono esclusi o marginalizzati i caratteri distintivi di provenienza da un certo produttore ed origine da un certo territorio che hanno costituito, per secoli, le informazioni fondamentali per ciascuna scelta di acquisto. L'informazione assurge così ad elemento centrale per la tutela del consumatore, ed un rilievo del tutto peculiare essa assume nel mercato degli alimenti, che trae le proprie peculiarità dalle merci - gli alimenti - che in esso circolano. L'informazione della quale si tratterà è quella posta a vantaggio del consumatore (strumentale alla tutela dello stesso) e quella posta a vantaggio del professionista (strumentale alla competizione concorrenziale), e sarà analizzato cosa deve e cosa può essere oggetto dell'informazione, e come tale informazione debba o possa essere veicolata, tenendo conto in particolare della ratio che informa una tanto dettagliata disciplina. Particolare attenzione sarà infine rivolta alle informazioni nutrizionali e sulla salute, sulle quali convergono interessi talvolta antagonisti tra loro (libertà di iniziativa economica, tutela della salute del consumatore; lealtà della competizione concorrenziale; tutela degli interessi economici dei consumatori). Proprio tali indicazioni rappresentano l'ultima frontiera della competizione tra operatori alimentari e, al contempo, la più recente insidia per gli interessi dei consumatori.
In the modern markets the circulating goods are recognizable only by their gender; the provenance from a certain producer or the origin from a certain place, elements that have been for centuries the fundamentals information for each consumer choice, are nowadays excluded or marginalized. Information became a central element of the consumer protection, and takes a special position in the food market, that takes its peculiarity from the goods – food products – that circulate in it. We will focus on the information to the consumer (functional to its protection) and on the information for the entrepreneur (functional to the commercial competition). We will analyze what “have to” and what “can be” the object of the information, and the ways of transmission of these information, taking into account the ratio of the entire legislation. A special attention will be reserved to the nutritional claims and health claims, that sometimes involve antagonistic interests. These indications represent the last frontier of competition between food operators and, at the same time, the latest trap for consumers’ interest.

Fornendo energia e nutrienti, la produzione di cibo è essenziale per la vita. Tuttavia, essa rappresenta anche una criticità ambientale. La popolazione mondiale in rapida crescita, infatti, ha bisogno di un quantitativo di cibo sempre maggiore, una delle principali cause di degrado ambientale a livello globale. Il sistema agricolo è fondato su una rete di relazioni complesse che collegano la produzione agricola, funzioni e condizioni ambientali. Una produzione agricola meno impattante è, quindi, fondamentale per non compromettere la possibilità per la future generazioni di avere accesso a un quantitativo adeguato di risorse. La metodologia LCA (life cycle assessment) ha un ruolo centrale nella valutazione di sostenibilità. Analizzando l’intero ciclo di vita di un prodotto o servizio, infatti, permette di tenere in considerazione eventuali trasferimenti di impatti tra comparti ambientali o fai della filiera. Il principale obiettivo della presente tesi è contribuire al dibattito in corso riguardo all’armonizzazione degli approcci nell’applicazione della metodologia LCA a prodotti agro-alimentari per favorirne l’affidabilità e l’efficacia.
Providing energy and nutrients, food production is essential for life. However it represents also an important environmental concern. Indeed, the rapidly growing world population is requiring an increased food production which is one of the greatest causes of environmental degradation throughout the world. The agricultural system is based on complex relations that link agricultural productivity, environmental functions and environmental conditions. Therefore, moving towards less polluting production systems is of the utmost importance to satisfy the current demand for food without compromising the possibility for future generations to have access to a proper amount of food of adequate quality. Life cycle assessment (LCA) methodology is at the core of sustainability assessment. Indeed, considering the entire life cycle of a product or service, it allows to account for potential shifts of environmental impacts between environmental compartments or stages of the food supply chain. The overall aim of the present thesis is to contribute to the ongoing debate on the harmonisation of the approaches to carry out a LCA referred to agro-food products in order to foster its reliability and effectiveness.

Streszczenie:

Recent decision in European environmental policy to increase the share of renewable energy will lead to an increased demand also for energy by farm. The multiplicity and heterogeneity of biomass and of energy products is also reflected in different types of energy conversion processes and different technologies for energy generation. These activities represent an important diversification of the agricultural production, in certain cases and certain situations the economic performance foreseen are of great interest and significance. Actually, the most interesting agro-energy chains are anaerobic fermentation in order to produce the biogas and the thermochemical process of wood biomass to produce directly energy or others energy carriers (bio-oil, bio-char, syngas). Therefore, the sustainability of any agro-energy chains depends not only by technical -economic issues (those routinely investigated and verified): energy and environmental aspects (as happens more often) must be take in account. These two aspects are not easy to quantify and have been neglected. Only the parallel verification of the economic, energetic and environmental results (EEE) can fully clarify the sustainability of a chain of bio-energy. Thus, the possibility to have a model that calculates, in an analytical and uniform way, costs (inputs) and benefits (outputs) of each chain by defining the balances EEE, allows: - to identify those at greater sustainability - to compare objectively the various technical solutions available, providing valuable information on strategies for promotion of agro-energy. Although in recent years, the study of energy and environmental balance of the agro-energy chains has attracted growing interest, most studies refer to the production of biofuels (pure oil, biodiesel, bioethanol) and operative conditions different than Italian. From the practical point of view, the assessment of different energy and environmental aspects however, is much more difficult than technical-economic. Indeed, the failure to define a common methodology, plus the substantial gap (or, however, the strong heterogeneity) between the parameters used from time to time. Only recently, worldwide and in Europe, have been set up working groups for harmonization and standardization of methodologies developed and in order to define how their use in different situations. It is also noted even if available the methodologies for assessing the input-output (as for example the Life Cycle Assessment - LCA) may be redundant and excessively costly in terms of economic resources, both human because the evaluation is not limited to these three aspects (EEE) of the agro-energy chains but investigates also other perspectives (eg. eutrophication, acidification, etc.) for which the search parameters calculation is even more difficult if not impossible. It follows that, in literature, regarding the same agro-energy chain can easily find different results, even divergent. These discrepancies suggest that doubts and uncertainties in decision making, depend primarily by the non-use of the same calculation methodology, but they are also found in tests carried out homogeneously by using the same methodology. The development of an analytical calculation model, able to fill those gaps and perform a detailed analytical assessment, thus provides a working tool that optimizes the choice between different agro-energy chains and allows to detect, in each operational situation, the one offering the best overall sustainability. The objective of the project is to define a calculation method based on indications recently provided by major international working groups (the Kyoto Protocol, IPCC, Task38, etc.), its subsequent implementation through the development of a model calculation and its utilization in order to evaluate the most widespread agro-energy chains. This model calculation, flexible and easy to use, will be able to determine: - Economic Balance (Outcome/Costs); - Energetic Balance (EOUT/EIN); - GHGs Balance (t CO2AVOIDED/t CO2EMITTED). These balances (briefly "budgets EEA") are calculated by analyzing the flow - incoming and outgoing - of mass, energy and emissions of greenhouse gases (GHGs - CO2, CH4, N2O expressed in terms of CO2 equivalent) related all the phases of the agro-energy investigated. To this end, however, it is necessary to advance the development of a methodology to calculate specific, uniform and flexible and the detection of conversion parameters homogeneous and characteristic of our agri-territorial system. These methodological steps are essential to allow the analysis of the various conversion technologies currently available and to make comparison of their performance. Furthermore, the model must allow the integration of the energy and environmental performance with economic and technical ones, giving way to represent the overall sustainability of the various technology solutions combined with energy generation from dedicated biomass and agricultural byprodutcs. This index is a real index of general efficiency that, combining all aspects associated with each currently viable technical solution allows to quantify the ability to contribute to the improvement of the agricultural system in terms of, first, diversification and increase the value of products (output) and, second, direct or indirect reduction of inputs (input). Through the overall sustainability is possible to make a strict comparison of the various solutions currently available to the agricultural sector in the field of energy conversion of its residues (crop byproducts, wastes) and, consequently, to assess the real capabilities that these agro-energy may have in improving the efficiency of agriculture not only in terms of diversification and increased value of products leaving the system, but also in reducing the direct or indirect input. In order to obtain specific parameters able to be used in the calculation model some different field tests have been carried out to determine technical-economic and energetic-environmental characteristics of operative machines employed in the field phase of the chains. Subsequently, by using the software the most common agro-energy chains have been evaluated.

Questa tesi di dottorato ha riguardato il recupero di composti ad alto valore aggiunto dai sottoprodotti agro-alimentari e il loro utilizzo in campo alimentare. In particolare, si è studiato il frazionamento lignocellulosico di raspi d’uva e residui di potatura di melo per ottenere emicellulosa, cellulosa, lignina e antiossidanti attraverso processi di auto-idrolisi e organosolv, investigando successivamente l’influenza di sei cultivar sul frazionamento lignocellulosico dei raspi. Un processo composto da quattro fasi (trattamento di lavaggio seguito da un’idrolisi acida, un’idrolisi basica e, infine, una decolorazione basica) è stato applicato su raspi di uva rossa (Barbera, Pinot Noir, Nebbiolo) e bianca (Müller, Chardonnay and Moscato). I raspi sono stati confrontati in termini di composizione chimica della materia prima (umidità, ceneri, minerali, lipidi, fibre, proteine zuccheri liberi) e di frazioni recuperate ( lavaggio, liquors acidi e basici e residui di cellulosa finali). Si è inoltre studiato l’influenza varietale sull’estrazione di antiossidanti da vinacce di Barbera, Pinot Noir and Nebbiolo, i diversi estratti sono stati confrontati per il loro profilo fenolico e per la loro capacità antiossidante. Infine, un estratto liofilizzato di vinacce di Barbera è stato utilizzato per migliorare la shelf-life di una pasta di nocciole valutando l’ossidazione cinetica.

The different stalks were compared in terms of chemical composition of raw material (moisture, ash, minerals, lipids, fiber, proteins, free sugars) and of the recovered fractions (washing, acid and basic liquors and final cellulose residues). We also studied the influence of variety on the antioxidants extraction from Barbera, Pinot Noir and Nebbiolo grape marc. The different extracts were compared in terms of phenolic profile and antioxidant capacity. Finally, a freeze-dried extract from Barbera grape marc was used to improve the shelf-life of hazelnut paste evaluating the oxidation kinetics.

Les Mesures agro-environnementales territorialisées (MAEt) ont été introduites en France pour la programmation 2007-2013 de la Politique Agricole Commune (PAC). La perspective de la réforme de la PAC offre l'opportunité de proposer des pistes d'amélioration de ces mesures. Cette thèse évalue dans une première partie ce dispositif MAEt avec une attention particulière portée aux enjeux de lutte contre les pollutions de l'eau d'origine agricole. Nous étudions dans le premier chapitre la décentralisation croissante du dispositif agro-environnemental, le ciblage et l'adaptation aux territoires à enjeux prioritaires. Cette analyse est illustrée par les résultats d'une enquête menée à l'échelle nationale auprès des agriculteurs éligibles et des agents responsables de la mise en œuvre des MAEt, avec deux focus sur l'Eure et Loir et le Languedoc-Roussillon. Ces analyses complémentaires nous permettent d'apporter des éléments d'explication au trop faible taux d'adoption des mesures de réduction d'intrants. Dans le deuxième chapitre nous estimons avec des méthodes économétriques d'évaluation des effets de traitement si ces mesures, basées sur une auto-sélection des participants, permettent effectivement de réduire l'utilisation d'herbicides par les viticulteurs engagés dans la région Languedoc-Roussillon. La seconde partie de la thèse propose deux dispositifs innovants qui pourraient améliorer l'acceptabilité des MAE par les agriculteurs. Nous étudions dans le chapitre 3 l'effet de l'introduction d'une dimension collective dans les contrats, par la méthode de modélisation des choix appliquée au cas des viticulteurs du Languedoc Roussillon. Cette dimension collective se concrétise par un ‘bonus' monétaire versé à chaque viticulteur engagé à condition qu'un objectif de surfaces engagées soit atteint collectivement. Pour finir, nous analysons dans le chapitre 4 la possibilité d'utiliser des appels à projets pour allouer les contrats agro-environnementaux, sur la base de l'expérience pilote menée par l'Agence de l'Eau Artois-Picardie. Ce mécanisme laisse aux agriculteurs la liberté d'adapter le cahier des charges et les montants des mesures en fonction de leur propre consentement à recevoir
Territorialized agri-environmental measures (MAEt) were introduced in France for the 2007-2013 Common Agricultural Policy program. The forthcoming CAP reform is an opportunity to improve the design of existing agri-environmental schemes. The first part of this thesis assesses this scheme (MAEt), with special attention paid to water pollution issues. In the first chapter we analyse theadvantages and limits of the partial decentralization of decision-making in the setting-up of agrienvironmentalprojects and of improved targeting through the identification of eligible priority areas.This analysis is illustrated by the results of a national survey conducted with eligible farmers andagents in charge of the implementation of the scheme and by two case studies conducted in Eure etLoir and Languedoc-Roussillon. These surveys help us to identify the reasons for the too low adoptionrates of pesticides reduction measures by farmers. In the second chapter, we estimate the impact ofherbicide reduction measures adopted by winegrowers in the Languedoc-Roussillon region using atreatment effects approach. The second part of the thesis proposes two innovative designs aiming atincreasing the acceptability of agri-environmental measures by farmers. In chapter 3 we study theintroduction of a collective dimension in the contracts. This collective dimension relies on a monetary‘bonus’ paid to each farmer who has signed a contract, provided that the proportion of landcollectively enrolled in the agri-environmental scheme reaches a predefined threshold. We finallyanalyse in chapter 4 the possible use of reverse auctions for the allocation of agri-environmentalcontracts, on the basis of the pilot experiment implemented by the Water Agency in Artois-Picardie.This mechanism enables farmers to adapt the practices they commit to and the payment that they receive to their own willingness to accept

A-kinase anchoring proteins (AKAPs) restrict the action of the broad-specificity cyclic AMP-dependent protein kinase (PKA) to discrete subcellular locations. The highresolution crystal structure of the docking and dimerisation (D/D) domain of the RIIa regulatory Bubunit of PKA in complex with the high-affinity anchoring peptide AKAP-IS explains the molecular basis of AKAP specificity for PKA regulatory subunits. AKAPIS folds into an amphipathic a-helix that engages an essentially preformed shallow groove on the surface of the RUa dimer D/D domains. Conserved AKAP aiiphatic residues dominate interactions to RUa at the predominantly hydrophobic interface, whereas polar residues are important in conferring regulatory subunit isoform specificity. Structural information for the AKAP family was previously limited to studies of the PKA-AKAP interface. To address this deficiency, a bioinformatic screen of AKAPs was performed to identify domains within AKAPs that might be suitable for structural investigation. A central domain in AKAP18 was identified, and its crystal structure was solved. The domain is structurally similar to 2H phosphoesterase enzymes, which catalyse the hydrolysis of cyclic nucleotides, with a central groove at the base of which two His-x-Thr motifs are positioned. The domain binds specifically to 5' AMP/CMP, with a dissociation constant for AMP in the physiological range, and the molecular basis for nucleotide specificity has been established. No catalytic activity was associated with the domain, so it may function as an AMP sensor. AKAP79 is a prototypical mammalian scaffold protein, which nucleates mUlti-protein kinase-phosphatase complexes, and localises at the cell membrane under the control of calmodulin. A system for expression and purification of AKAP79 has been developed enabling sufficient production of pure AKAP79 complexes for structural and biochemical investigation. Imaging of an AKAP79-PKA-calmodulin complex by negative-staining transmission electron microscopy indicates that the first three-dimen'sional reconstruction of this complex may be possible in the near future.

ABSTRACT AGRI-TOURISM: AS A NEW ELEMENT OF RURAL DEVELOPMENT DemirbaS Topcu, Elif MS., City and Regional Planning Department, Urban Design Supervisor: Assoc. Prof. Dr. Baykan Gü
nay October 2007, 187 Pages This thesis study is developed under the lights of new developments related to rural tourism sector in the world. With the effects of emerging term &lsquo
sustainability&rsquo
in 1980s, sustainable tourism concept has found new implementation areas. The increasing demand on the tourism activities taking place in rural areas has lead the governments to find ways of benefiting from this tendency in a sustainable way. Since the early 1990s, a new type of rural tourism called as agri-tourism has been developed as a concept that integrates agriculture and tourism activities in the western world. Whether it is evaluated as a tourism or agriculture development element, it is a new element of country planning. Nowadays, it is seen that there is also a new tendency for agri-tourism at local level through local initiatives in Turkey. Although there is still no governmental regulation for agri-tourism activities, political and practical developments demonstrate that the sector should be evaluated as a planning element for Turkey. The main purpose of this study is examining the rural development element characteristic of agri-tourism concept as an element for enhancing the rural tourism activities in Turkey. To achieve the purpose, two examples from EU- Lublin and Tuscany Regions were examined to understand the dynamics of agri-tourism as a planning element. For these study interpretative-comparative-textual method is used. Accordingly, the present condition in Turkey is evaluated through the obtained data and SWOT Analysis method was employed for analyzing the data. Accordingly, some suggestions are presented for developing agri-tourism sector in Turkey.

Pollinators provide essential services to crop and wild plants. Declines of native and managed pollinators have prompted considerable interest in the identity and importance of native pollinators and the services they provide. In agro-ecosystems there is particular concern over the impact of landscape simplification on these communities of 'service providers' , This thesis has two main aims; First, to investigate the ecosystem service of crop pollination by native insects, using ecological networks as a tool to identify pollinator interactions with crops, natural and semi-natural habitats. Pollination services to Fragaria x ananassa (strawberry), an insect-pollinated, high value crop, were used as a model system for this work. Networks were used to study interactions and spillover of insects between crop and semi-natural habitats at the local scale, the potential effects of poll in at or extinctions on pollination services, as well as pollen-transport interactions at the field scale and how they are affected by the structure of the surrounding landscape. The second aim of the thesis is {o explore the effects of sampling bias, specifically the type of sampling methodology employed, on the structure of the resulting plant-pollinator networks. The work presented in this thesis demonstrates the wide range of possible applications of plantpollinator networks to the study of crop pollination. The results reveal temporal changes in pollinator importance, spillover of pollinators across boundaries between crop and seminatural habitats and negative effects of landscape structure on pollinator communities and their interactions along with significant impacts of sampling bias on network structure. Network approaches to conservation issues reveal hidden effects of anthropogenic change on biodiversiry and are likely to be increasingly employed for such purposes in the future. The thesis ends by highlighting areas for improvement in the application of plant pollinator networks to the study of plant-pollinator community structure and pollination services, in order that ecologists gain the maximum benefit from using networks to answer questions about the effects of human activity on plant-pollinator communities and interactions.

Slaughterhouse waste (SB) has high potential to be utilized in anaerobic digestion due to its high protein and lipid content. However, these are also the limiting factors of system stability. Thus, co-digestion of slaughterhouse waste with other agro-industrial residues (manure (M), various crops (VC) and municipal solid waste (MSW)) was introduced in this study to overcome this problem. The main objective of the work was to determine the operating parameters and the methane yield in semi-continuous co-digestion of slaughterhouse waste with other agro-industrial waste streams. Four continuously stirring tank reactors (CSTRs) with different substrates and mixtures (SB, SB:M, SB:VC and SB:VC:MSW) were started up operating with hydraulic retention time (HRT) of 25 days in thermophilic conditions. The highest organic loading rates which could be achieved were 0.9 g VS/L·d in digestion of SB and 1.5 g VS/L·d for the co-digestion mixtures. In these cases, average methane yields of 300, 510, 587 and 426 ml/g VS were obtained from the digestion of SB, and the co-digestion of SB:M, SB:VC and SB:VC: MSW, respectively, with methane contents in the biogas of 60-85%. The highest average methane yield of 587 ml/g VS was found in co-digestion of SB:VC, which was in accordance with the value of 592 ml/g VS detected during the batch digestion of the same mixture. Moreover, batch assays with different substrates as well as 11 different mixtures of those were also set up to investigate the methane potential and the effect of second feeding. The results showed that the co-digestion of SB:VC, SB:VC:MSW and SB:M could provide high methane potentials, where the highest methane yields of 592, 522 and 521 ml/g VS, respectively were obtained. Moreover, increasing, similar or decreasing methane yields were determined from the second feeding depending on the substrates and substrate mixtures used.

El desarrollo del presente Plan Estratégico se hace en un momento muy complicado para el sector azucarero peruano, donde el mercado interno está cubierto, presenta excedentes y el Estado facilita la importación de azúcar con la intervención en los precios. Existe una brecha importante entre las empresas azucareras nacionales y las empresas azucareras líderes a nivel mundial en cuanto a la capacidad de producción, por lo que aún el sector azucarero peruano debe desarrollarse para ser competitivo a nivel regional en un primer momento y luego a nivel mundial. Es necesario integrar al sector para lograr mejores posiciones en los negocios del ámbito de la exportación. Por lo expuesto, se presenta una competencia agresiva que reafirma la importancia de la necesidad de diferenciación para Agroindustrial Paramonga S.A.A. (AIP) respecto al azúcar en la orientación al liderazgo en costos. En las estrategias propuestas se ha considerado desarrollar nuevos negocios relacionados a la actividad principal de AIP como son los productos para agroexportación y los vinculados con el azúcar. Las estrategias elegidas con el proceso del Planeamiento Estratégico deben llevar al logro de la visión donde al 2025 Agro Industrial Paramonga S.A.A. será reconocida como una empresa competitiva en el sector azucarero del Perú, diversificada con productos agroindustriales, productos derivados del azúcar, orientados al mercado local e internacional, en armonía con la comunidad vinculada y el medio ambiente
The development of this Strategic Plan is done in a very difficult time for the Peruvian sugar sector, where the domestic market is covered, has surplus and the Peruvian government facilitates the import of sugar with price intervention. There is a significant gap between domestic sugar companies and sugar leader companies worldwide in terms of production capacity, so that even the Peruvian sugar sector must develop to be competitive at the regional level at first and then globally. It is necessary to integrate the sector to achieve better positions in the business field of export. For these reasons, aggressive competition reaffirms the importance of the need of differentiation for Agroindustrial Paramonga S.A.A. (AIP) related to the sugar cost leadership orientation. In the proposed strategies they have been considered the development of new business in connection to the core business of AIP products such as agricultural exports and sugar derivatives. The strategies chosen with the strategic planning process should lead to achieving the 2025 vision where Agro Industrial Paramonga S.A.A. will be recognized as a competitive company in the sugar sector, diversified agro-industrial products, sugar products, aimed at local and international markets, in harmony with stakeholders and the environment

INKA AGRI RESOURCES S.A.C., es una empresa de capital chino constituida en 2017 que, se dedica a la importación y comercialización de fertilizantes genéricos, compuestos y solubles (commodities), para el sector agrícola en el mercado peruano. El objetivo de la consultoría fue identificar el problema principal que no le permite a la empresa alcanzar sus objetivos, analizando las principales causas y proponiendo alternativas de mejora que mitiguen el impacto operativo y económico. Se identificó que el problema principal son las pérdidas de ventas por la falta de abastecimiento de productos fertilizantes commodities y especialidad, en torno al no logro de la meta anual de 90% de sus ventas presupuestadas para ambas líneas de productos. Luego de varias reuniones de trabajo con la gerencia general y las gerencias de primea línea, se detectó que la causa raíz a su problema estaría relacionada con la falta gestión estratégica y marketing, falta de seguimiento a la liberación de orden de compra por la gerencia comercial y el área de Créditos y Cobranzas y la falta de pronóstico de ventas. Es con base en el análisis externo e interno y la literatura investigada que se propone una serie de acciones para que la empresa pueda alcanzar sus objetivos, reforzando su propuesta de valor de la marca en el mercado nacional, planteando estrategias de marketing mix segmentada, implementando herramientas de pronóstico de ventas, y estableciendo controles a través del Tablero de Mando Integral que corrobore el impacto generado por las iniciativas recomendadas. No obstante, la evaluación económica y financiera demostró la viabilidad del proyecto en dos escenarios: Optimista y Pesimista. En el escenario optimista, el valor actual neto es de S/. 7,253, 940.68, la tasa de retorno de 19.28%, y el periodo de recuperación es menor a un año. Por su parte, en el escenario pesimista, el valor actual neto es de S/. 4, 117,506.36, la tasa de retorno de 5.14%, y el periodo de recuperación es menor a un año.
INKA AGRI RESOURCES S.A.C., is a company with Chinese capital established in 2017 that is dedicated to the import and commercialization of generic, compound and soluble fertilizers (commodities) for the agricultural sector in the Peruvian market. The objective of the consultancy was to identify the main problem that does not allow the company to achieve its objectives, analyzing the main causes and proposing alternatives for improvement that mitigate the operational and economic impact. It was identified that the main problem is the loss of sales due to the lack of supply of fertilizers, commodities and specialty products, around the failure to achieve the annual goal of 90% of its budgeted sales for both product lines. After several work meetings with the general management and the first-line managers, it was detected that the root cause of their problem would be related to the lack of strategic management and marketing, lack of follow-up to the release of the purchase order by the commercial management and the area of Credits and Collections and the lack of sales forecast. It is based on the external and internal analysis and the researched literature that a series of actions are proposed so that the company can achieve its objectives, reinforcing its brand value proposition in the national market, proposing segmented marketing strategies, implementing sales forecasting tools, and establishing controls through the Integral Dashboard that corroborates the impact generated by the recommended initiatives. However, the economic and financial evaluation demonstrated the viability of the project in two scenarios: Optimistic and Pessimistic. In the optimistic scenario, the net current value is S/. 7, 253,940.68, the rate of return of 19.28%, and the payback period is less than one year. On the other hand, in the pessimistic scenario, the net present value is S/.4,117,506.36, the rate of return of 5.14%, and the payback period is less than one year.

L'activite agricole et agro-industrielle qui ont fait l'objet de cette etude concerne essentiellement la partie nord-est de l'oriental, c'est-a-dire l'ensemble de la province d'oujda et la partie est de la province de nador. L'agriculture constitue le secteur d'amont qui fournit les divers produits agricoles, par contre, l'agro-industrie est le secteur d'aval ou s'achemine la production vers la transformation. Dans l'etude des activites agro-industrielles (minoteries, laiteries, sucreries, huileries, conditionnement d'agrumes et de maraichage. . . ), nus avons poursuivi l'acheminement de la production agricole de l'exploitation a l'entreprise qui transforme et commercialise les produits traites. L'etat joue un role primordial dans l'organisation de la relation entre l'amont et l'aval. C'est lui qui encourage les cultures contractuelles et integrees pour developper la production agricole. La relation contractuelle permet a l'agro-industrie de controler assez strictement la production d'un ensemble d'exploitations, sans posseder la terre ni courir les risques de la culture.

Mestrado em Engenharia Mecânica
Com o presente trabalho pretende-se fazer um estudo sobre a cinética da secagem do bacalhau nomeadamente no que se refere à determinação das humidades de equilíbrio e ao estudo da cinética da secagem. A determinação das humidades de equilíbrio foi conseguida usando uma câmara higrométrica existente no Departamento de Engenharia Mecânica, onde foram variados os parâmetros de secagem, temperatura e humidade relativa. A cinética da secagem do bacalhau foi determinada com recurso a uma estação de secagem existente no Departamento de Engenharia Mecânica. Foram obtidas as curvas de secagem em várias condições de secagem. Nas experiências realizadas na estação de secagem, foram variadas a humidade relativa (40,50 e 60%), a velocidade do ar (1.5m/s e 3m/s) e manteve-se constante a temperatura (20ºC). Após o tratamento e discussão dos resultados verificou-se que a um aumento da temperatura provoca uma diminuição no valor da humidade de equilíbrio e um aumento da humidade relativa provoca um aumento da humidade de equilíbrio. Na estação de secagem verificou-se que um aumento da velocidade de secagem provoca uma diminuição do tempo de secagem e um aumento da humidade relativa provoca um aumento do tempo de secagem. ABSTRACT: With this work we intend to do a study on the drying kinetics of salted cod. Namely in what determination of concerns the drying equilibrium drying kinetics. In order to determine the moisture drying equilibrium an hygrometric chamber was used. A convective drying station was used to study the drying kinetics of salted cod. In the experiments carried out on the drying station relative humidity and air speed was varied while temperature remained constant (20ºC). After treatment and discussion of the results has shown that an increase in temperature causes a decrease in the amount of humidity equilibrium while the effect was varied when relative humidity was increase. Drying kinetics is accelerated by an increase in the air velocity and reduced by an increase in the relative humidity.

Streszczenie:

Inactivation of p53 by mutation occurs in half of human tumours. The majority of these mutations affect the DNA-binding core domain and hence impair DNA binding and hinder transcription of p53 target genes. A wealth of data indicates that even cancers carrying wild type p53 protein, evolve mechanisms to render the p53 pathway inactive. Thus, inactivation of the p53 response, either by mutation or the alternative mechanisms, allows unpurturbed tumour growth. Recent work identified Anterior Gradient-2 (AGR2) as a protein overexpressed in wild type p53 expressing tumours and it was subsequently shown that AGR2 inhibits p53 pathway. In this study I confirmed that AGR2 protein inhibits p53 and AGR2 depletion potentiates p53-dependent DNA damage response. As there were no physiological signals known that regulate the AGR2-p53 axis, here I set out to identify pathways that activate or inhibit AGR2. I found that transforming growth factor β(TGF- β) triggers AGR2 protein reduction and this is concomitant with the stabilisation and increased activity of p53 protein. TGF-β halts AGR2 transcription in a SMAD4- dependent manner and triggers AGR2 protein degradation involving an ATM kinase. I found that SMAD nuclear interacting protein (SNIP1) mediated the ATMdependent AGR2 degradation. Interestingly, SNIP1 overexpression by itself promoted AGR2 protein degradation. I found that AGR2 protein degradation was proteasome independent and involed autophagy-lysosomal degradation pathway. As the mechanism of p53 inhibition by AGR2 is not known, I reasoned that identifying interactors of AGR2 may potentially further our understanding of the mechanism accounting for AGR2-mediated p53 inhibtion. I isolated the ATP binding protein Reptin in the yeast two-hybrid system and subsequently validated it as an AGR2 binding partner. Mutations of the two ATP binding motifs in Reptin resulted in altered oligomerization and thermostability of Reptin and affected the AGR2-Reptin complex stability. I also identified the Reptin docking site and it was mapped to a divergent octapeptide loop. I found that AGR2-Reptin complex coimmunoprecipitated with the p53 protein. Subsequently, I showed that Reptin protein can influence p53 activity, and depending on local concentration, either inhibit the transcription of p53-genes or chaperone its DNA binding activity. Interestingly, I found that Reptin formed a stable complex, independent of AGR2, with p53 R175H, p53 F270A, p53 S269D and p53 S269A, which has implication for the Reptin function in cancers bearing mutant form of p53 protein.

El Sector Agro Exportador Peruano está pasando por una etapa de rápido crecimiento como consecuencia de la apertura comercial que el Perú viene experimentando en las últimas décadas, así como por la variedad, diversidad y calidad de los productos que se ofrecen al mercado internacional. Para un mejor aprovechamiento de esta situación y con la intención de darle sostenibilidad al crecimiento del sector se hace necesario plantearse estrategias que permitan la obtención de ciertos objetivos futuros. En ese contexto el presente trabajo describe en forma secuencial y sistémica el desarrollo de un plan estratégico orientado hacia el cumplimiento de una visión para el sector agro exportador hacía el año 2025 (situación futura deseada), partiendo de un análisis de la situación actual del sector, su entorno externo e interno hasta obtener un diagnóstico general de la situación. Posteriormente y en base al diagnóstico, se desarrollan las estrategias necesarias para alcanzar los objetivos de largo plazo que se traducirán en el cumplimiento de la visión o situación futura deseada para el año 2025

Streszczenie:

Le droit de l'alimentation restreint le champs des regles obligatoires, ce qui laisse plus de liberte aux professionels. Ils doivent amenager cette liberte en tenant compte du fait que la salubrite des denrees agro-alimentaires est consideree comme un "bien public" donc, la production ne peut etre laissee a la seule initiative privee. La mise sous assurance qualite, en tant qu'instrument privilegie permettant de garantir la protection de ce bien public, est destine a se developper. Une approche plus simple de l'assurance qualite, la methode haccp a d'ailleurs ete integree dans la legislation communautaire. Les nouveaux types de relations economiques qui s'instaurent, a la suite de la mise sous assurance qualite des entreprises agro-alimentaires, modifient les relations juridques entre les acteurs de la filiere. L'assurance qualite permet d'adopter au client les garanties de satisfaction qu'il recherche quant a la regularite de la qualite des denrees agro-alimentaires commandees. Une veritable relation de collaboration peut s'etablir entre eux. Elle se repercute sur la methode de travail des salaries et sur les exigences imposees aux producteurs agricoles en amont de la filiere. En outre, l'assurance qualite rend plus difficile le controle officiel des denrees agroalimentaires et la constatation de l'element materiel de l'infraction penale. Les agents de la dgccrf doivent donc evoluer vers des methodes de controle plus sophistiquees, vers l'audit l'assurance qualite n'a pas veritablement d'influence sur la responsabilite civile des fabricants. Toutes deux reposent sur une approche differente de la responsabilite
The european food law limits the field of compulsory rules, that let more liberty to professionals. They must arrange it, taking into consideration the fact that healthiness of foods is considered as a "public asset". The production can't be let to the only private initiative. Quality insurance is a good means to take this necessity into consideration. A more simple approach of quality insurance, is haccp method, which has been integrated into european law. The new type of economic relation s which are established, following the putting of quality insurance into food plants, modify the legal relations between the participant in agrobusiness channels. The supplier informs the customer by giving him previous and finals proofs that the products will futil its requirements. A real collaboration can be established between both of them. This collaboration has got consequences upon employees working methods and requirements imposed to farmers (suppliers of the agrobusiness plant). Moreover, control on food is becoming more and more difficult, as well as the verification of the intentionnal element of penal infringements. The officers in charge of public control must develop more sophisticated method of control. Quality insurance doesn't have a main influence upon manufacturers civil liability. Both of them are based on adifferent approach of liability
