Resumen
Purpose Automated flow line manufacturing systems are becoming more and more relevant in industry, especially in the food and beverage sector. Improving the efficiency of automated flow line manufacturing systems is the core objectives of all companies as measured by the overall equipment effectiveness (OEE) index. The purpose of this paper is to carry out an innovative micro downtime data collection and statistical analysis in the food and beverage sector; it introduces a numerical indicator called “Cost Performance Indicator-CPI” to estimate the performance improvement of investment activities. Moreover this analysis will be used as a basis to carry out a new simulative model to study micro downtime of automatic production lines. In addition, the presented micro downtime data collection and statistical analysis will be used to construct a new simulative model to support improvement activities. Design/methodology/approach Descriptive and statistical analyses are carried out about OEE, time to repair (TTR) and time to failure (TTF) data. The least efficient production line is identified and principal causes of inefficiency are investigated. Micro downtime (downtime lower than 15 minutes) covers 57 percent of inefficiency. Investigations are carried out into the three principal machines affected by this inefficiency. The study then investigates the causes of micro downtime of these machines using ad hoc data collection and analysis. The probability distributions of TTF and TTR are evaluated and an analysis of micro downtime causes and a cause-effect is carried out. The most attractive investment in terms of recoverable OEE (1.44 percent) and costs is analyzed through the calculation of a CPI. One of the conclusions is to recommend the introduction of a payback period with a variable contribution margin. Findings This study get the basis for the construction of a new simulative model based on ad hoc micro downtime probability distributions, applied in automated flow line manufacturing systems. It gives an effort to downtime analysis in automated production lines and a guideline for future analysis. Results of this study can be generalized and extended to other similar cases, in order to study similar micro downtime inefficiency of other production lines. The statistical analysis developed could also potentially be used to further investigate the relationship between the reliability of specific machines and that of the entire line. Originality/value The case study presents a new detailed micro downtime data collection and statistical analysis in the beverage sector with the application of a numerical indicator, the CPI, in order to drive future actions. In addition, the presented micro downtime data collection and statistical analysis will be used to construct a new simulative model to support improvement activities. Moreover, results can be generalized and used as a basis for other micro downtime analyses involving the main causes of inefficiency in automated production lines.

Resumen
Micro-milling forces, cutting temperature, and thermal–mechanical coupling are the key research topics about the mechanism of micro-milling nickel-based superalloy Inconel 718. Most current analyses of thermal–mechanical coupling in micro-milling are based on finite element or experimental methods. The simulation is not conducive to revealing the micro-milling mechanism, while the results of experiments are only valid for certain machine tool and workpiece material. Few analytical coupling models of cutting force and cutting temperature during micro-milling process have been proposed. Therefore, the authors studied coupled thermal–mechanical analyses of micro-milling Inconel 718 and presented a revised three-dimensional analytical model of micro-milling forces, which considers the effects of the cutting temperature and the ploughing force caused by the arc of cutting edge during shear-dominant cutting process. Then, an analytical cutting temperature model based on Fourier’s law is presented by regarding the contact area as a moving finite-length heat source. Coupling calculation between micro-milling force model and temperature model through an iterative process is conducted. The novelty is including cutting temperature into micro-milling force model, which simulates the interaction between cutting force and cutting temperature during micro-milling process. The established model predicts both micro-milling force and temperature. Finally, experiments are conducted to verify the accuracy of the proposed analytical method. Based on the coupled thermal–mechanical analyses and experimental results, the authors reveal the effects of cutting parameters on micro-milling forces and temperature.

Resumen
Cobalt alloy on chromium thin film magnetic media are used in industry computer hard disk drives because of their large values of coercivity (Hc), remanent magnetization (Mr), squareness (S*), and relatively low noise. The magnetic performance depends strongly on processing conditions and the resulting nanometer scale microstructure.A complete structure-processing-properties analysis requires effective measurement of magnetic and microstructural properties. To date, most structure-properties analyses have involved correlation of bulk magnetic (hysteresis loop) properties and magnetic recording measurements with physical microstructures observed by high-resolution SEM and TEM.The nanoscale microstructural features that dramatically affect magnetic properties are difficult to observe but careful TEM analysis has been used to observe subtle, important differences in the atomic scale physical microstructure. Even these impressive capabilities are becoming insufficient for continued development of improved magnetic recording media. Microstructural design is moving into a regime where appropriate control of magnetic properties requires control of elemental composition and second phase formation as well as crystallography and morphology, at near-atomic levels.

Resumen
Estimation of effective diffusion coefficients is essential to be able to describe the diffusive transport of solutes in porous media. It has been shown in theory that in the case of uncharged porous materials the effective diffusion coefficient of solutes is a function of the pore morphology of the material and can be described by their tortuosity (tensor). To estimate the apparent diffusion coefficients, the values of tortuosity and porosity should be known first. In contrast with calculation of porosity, which can be easily obtained, estimation of tortuosity is intricate, particularly with increasing micro-geometry complexity in porous media. Moreover, many engineering materials (e.g, clays and shales) are characterized by electrical surface charges on particles of the porous material which can strongly affect the diffusive transport properties of ions. For these materials, estimation of effective diffusion coefficients have been mostly based on phenomenological equations with no link to underlying microscale properties of these charged materials although a few recent studies have used alternative methods to obtain the diffusion parameters.
In the first part of this thesis a numerical method based on a recently proposed up-scaled Poisson-Nernst-Planck type of equation (PNP) and its microscale counterpart is employed to estimate the tortuosity and thus the effective and apparent diffusion coefficients in thin charged membranes. Beside this, a new mathematical approach for estimation of tortuosity is applied and validated. This mathematical approach is also derived while upscaling of micro-scale Poisson-Nernst-Planck system of equations using the volume averaging method. A variety of different pore 2D and 3D micro-geometries together with different electrochemical conditions are studied here. To validate the new approaches, the relation between porosity and tortuosity has been obtained using a multi-scale approach and compared with published results. These include comparison with the results from a recently developed numerical method that is based on macro and micro-scale PNP equations.
Results confirm that the tortuosity value is the same for porous media with electrically uncharged and charged particles but only when using a consistent set of PNP equations. The effects of charged particles are captured by the ratio of average concentration to effective intrinsic concentration in the macroscopic PNP equations. Using this ratio allows to consistently take into account electro-chemical interactions of ions and charges on particles and so excludes any ambiguity generally encountered in phenomenological equations.
Steady-state diffusion studies dominate this thesis; however, understanding of transient ion transport in porous media is also important. The last section of this thesis briefly introduces transient diffusion through bentonite. To do so, the micro Nernst-Planck equation with electro-neutrality condition (NPE) is solved for a porous medium which consists of compacted bentonite. This system has been studied before in another research using an experimental approach and the results are available for both transient and steady-state phases. Three different conditions are assumed for NPE governing equations and then the numerical results from these three conditions are compared to the experimental values and analytical phenomenological solution. The tortuosity is treated as a fitting parameter and the effective diffusion coefficient can be calculated based on these tortuosity values. The results show that including a sorption term in the NPE equations can render similar results as the experimental values in transient and steady state phases. Also, as a fitting parameter, the tortuosity values were found varying with background concentration. This highlights the need to monitor multiple diffusing ion fluxes and membrane potential to fully characterize electro-diffusive transport from fundamental principles (which have been investigated in first part of this thesis) rather than phenomenological equations for predictive studies.
This research has lead to two different journal articles submissions, one already accepted in Computers and Geotechnics (October 22, 2009, 5-yrs Impact Factor 0.884) and the other one still under review.

Resumen
Les techniques d'analyses médicales nécessitent le développement, à faible coût, de capteurs chimiques fiables. Dans ce contexte, les transistors chimiques à effet de champ CHEMFETs offrent des solutions innovantes à condition d'optimiser l'interface entre microtechnologies et biotechnologies. Au cours de cette thèse, nous nous sommes attachés à développer des techniques permettant de coupler espèces biologiques et silicium. Deux approches ont été étudiées, toutes les deux basées sur l'utilisation des polymères. La première approche a été centrée sur le développement des techniques d'encapsulation et de création de micro-volumes. Pour cela, des micro-cuves d'analyse ont été réalisées d'abord en plexiglas® puis en PDMS. Après l'optimisation des caractéristiques géométriques, le suivi de lactivité bactérienne a été effectué grâce au suivi du pH de la solution à l'aide de pH-ISFETs. Nous avons ainsi démontré la possibilité de détecter l'activité bactérienne dans le cas de Lactobacillus Acidophilus et commencé à déterminer la « signature » biologique de cette bactérie. La deuxième approche a été consacrée à l'adaptation des CHEMFETs à la détection enzymatique. Pour cela, nous avons envisagé d'utiliser un polymère en tant que matrice de support d'un élément biologique. L'utilisation des techniques de photolithographie a ainsi permis la fabrication collective de couches enzymatiques en PVA en vue d'une détection biochimique. Après avoir appliqué le protocole de dépôt mis au point à l'uréase, nous avons caractérisé l'évolution de l'activité enzymatique des membranes ainsi réalisées. Ensuite, nous avons validé ce procédé par la fabrication de microcapteurs chimiques de type ENFET et nous avons détecté des taux d'urée par le suivi des variations du pH au sein de solutions de différentes concentrations.

Resumen
Hisingen, i de västra delarna av Göteborgsregionen, är ett tillväxtområde både för industri och för bostäder. Till följd av detta väntas en kraftig trafikökning under de kommande åren. Väg 155 är en viktig länk för arbetspendling till och från de stora arbetsplatser som finns i området. Redan i dag upplevs kapaciteten på vägen som otillräcklig då rusningstrafiken flyter trögt. FB Engineering AB har av Vägverket Region Väst fått i uppdrag att ta fram ombyggnadsförslag som har kapacitet att klara den framtida trafikbelastningen på vägen. I examensarbetet jämförs fyra av dessa förslag som infattar trafikplatserna Oljevägsmotet och Vädermotet samt sträckan mellan och i anslutning till dessa trafikplatser. Analysen har gjorts med hjälp av trafiksimuleringsprogrammet TSIS. Trafiksimuleringsprogram är verktyg som allt oftare används för att utreda konsekvenserna av olika förändringar i vägnätet. Detta medför både ekonomiska- och tidsmässiga vinster i och med att programmen kan utvärdera olika förslag innan slutgiltiga beslut fattas. Utvärderingen av ombyggnadsförslagen visar att skillnaderna mellan alternativen är relativt små och att alla bidrar med en klar förbättring jämfört med den nuvarande utformningen. Det förslag som gav bäst resultat med hänseende till framkomlighet innefattar en ny länk som sammanbinder Oljevägsmotet direkt med Hisingsleden samt låter väg 155 vara genomgående i Vädermotet. Examensarbetet innehåller även en litteraturstudie som beskriver de olika modeller som används i  trafiksimuleringsprogrammen för att beskriva hur förarna beter sig i det simulerade nätverket. De modeller som har störst inverkan på förarbeteendet är modellerna för car-following och lane-changing. Dessa modeller beskriver hur förare i nätverket förhåller sig till varandra samt hur de agerar vid körfältsbyten. VISSIM och Paramics har liknande modeller där perceptuell psykologi används för att beskriva förarbeteendet. TSIS använder en car-followingmodell som bygger på att en förare alltid håller ett säkert avstånd till framförvarande fordon och en lane-changingmodell som bygger på att olika förare tar olika risker vid körfältsbyten. I examensarbetet har även en jämförelse gjorts mellan TSIS, VISSIM och Paramics. Jämförelsen inriktas på användarvänlighet och simuleringsresultat. Det program som har varit smidigast att arbeta med både när det gäller implementering och kalibrering har va rit VISSIM. Jämförelsen av simuleringsresultaten visar att VISSIM och Paramics resultatmässigt är likvärdiga medan TSIS skiljer sig något.

Resumen
En France, les prix des EHPAD sont élevés au regard d'une qualité qui semble insuffisante. Des projets de réformes sont en discussion, mais les pouvoirs publics sont face à un dilemme : toute recherche de réduction des coûts risque de dégrader la qualité plus qu'elle ne l'est déjà et toute amélioration de la qualité serait probablement inflationniste.L'objectif de cette thèse est d'étudier si ce dilemme peut être résolu, en analysant en particulier le rôle de la concurrence, réelle et par comparaison, qui pourrait être introduite dans ce secteur. Par une approche micro-économétrique, nous organisons notre analyse autour de trois questions de recherche : (i) que peut-on attendre des réformes proposées de la tarification et de l'augmentation de la capacité des établissements ? (ii) comment le développement du secteur privé lucratif pourrait permettre de réduire les prix et d'améliorer la qualité ? (iii) existe-t-il des contraintes environnementales responsables de la faible qualité des EHPAD? Nous observons, d'une part, que les projets de réforme permettraient de réduire l'inefficacité et donc éventuellement les prix des EHPAD, mais au détriment de leur qualité. D'autre part, nous constatons que l'essor des EHPAD lucratifs s'accompagne d'une augmentation des tarifs et d'une dégradation de la qualité de la prise en charge, qui pourraient être modérées par une structure de marché plus concurrentielle. Enfin, les EHPAD sont confrontés à des difficultés locales de fidélisation du personnel soignant qui affectent leur qualité et qui ne semblent pas pouvoir être résolues par un ajustement des salaires. Ces résultats peuvent servir de repères à la mise en place d'une politique publique adaptée.

Resumen
Nos connaissances de la diversité des communautés microbiennes marines ont longtemps été restreintes aux informations précieuses, mais incomplètes, issues de l’utilisation de méthodes de culture. Lors de cette étude, des techniques moléculaires (PCR, clonage, séquençage, hybridation, construction d’une banque métagénomique) et des marqueurs génétiques [ARNr 16S, gènes codants pour des enzymes spécifiques de la voie inverse du cycle tricarboxylique (acIB, oorA)] ont été utilisés pour contourner les limites inhérentes aux méthodes de culture et accéder à la diversité spécifique ainsi qu’aux fonctions des micro-organismes incultivés des sources hydrothermales profondes. Ce travail de recherche a permis de : -confirmer l’importance écologique des epsilon-Proteobacteria dans l’écosystème hydrothermal profond, notamment dans les processus de colonisation de surfaces vierges exposées aux fluides hydrothermaux. – de mettre au point une sonde oligonucléotidique spécifique des epsilon-Proteobacteria permettant de les quantifier et de les observer dans un échantillon environnemental. – de montrer la présence de bactéries Arcobacter-like vraisemblablement sulfo-oxydantes et qui seraient impliquées dans la formation d’un biofilm filamenteux contenant essentiellement du soufre. – Et d’obtenir via l’approche métagénomique, les premiers fragments génomiques d’Archea incultivées hydrothermales. Grâce à l’utilisation combinée de différentes approches moléculaires, ce travail a apporté un nouvel éclairage sur la diversité des communautés microbiennes de l’écosystème hydrothermal marin profond
Our knowledge of the diversity of marine microbial communities has long been restricted to the precious but incomplete information generated by the culture-based methods. In this study, molecular techniques (PCR, cloning, sequencing, hybridization, metagenomics library construction and genetic markers [16S rRNA, genes coding for enzymes specific to the reverse tricarboxylic acid cycle (acIB, oorA)] were used to circumvent the limits inherent to cultivation methods, and to obtain a more realistic view of the specific and functional diversity of the deep-sea hydrothermal vent microbial communities. This research allowed (i) to confirm the ecological significance of free-living epsilon-Proteobacteria at deep-sea hydrothermal vents, especially during in-situ colonization experiments (this study provides the first example of the prevalence and ecological significance of free-living Arcobacter-like at deep-sea hydrothermal vents, which are supposed to be sulfo-oxidizing bacteria involved in filamentous sulphur formation, (ii) to design and validate a 16S rRNA oligonucleotide probe targeting most of the epsilon-Proteobacteria found in hydrothermal systems, (iii) to obtain the physiology of yet uncultured groups of archea from deep-sea hydrothermal vents using metagenomics. By the combined use of variety of molecular approaches this work enlarges our view of the diversity of microbial communities in deep-sea hydrothermal vents

Resumen
Fuel cells are direct energy conversion devices to generate electricity. They have the lowest emission level of all forms of electricity generation. Fuel cells require no combustion of the fuel. The thermal energy gained from fuel cells may be utilized in micro turbines (gas turbines). In this work, first and second law analyses are performed on a hybrid system consisting of a solid oxide fuel cell (SOFC) combined with a micro turbine to be able to find an optimum point of pressure and corresponding mass ratio to gain maximum work output. Also another system with same equipments only without a gas turbine is investigated to see the effects of gas turbine. The analyses are performed utilizing a code written in MATLAB for each of the equipments. Fuel used is biomass with a certain concentration. To be able to use biomass in a fuel cell-micro turbine hybrid cycle, it is gasified and converted into a certain calorific value gas, with the use of gasifiers. In this study fluidized bed gasifier is utilized since it has the advantage of good mixing and high heat transfer leading to a uniform bed condition. Desulphuration and gas filter units will be implemented in order to clean the producer gas before being used in hybrid system. For a certain percentage of the fuel that may pass through the fuel cell without being used, a combustor is utilized. Optimum point mass and pressure ratios for system are MR = 0.6411 and Pr = 8. Gas turbine supplies more power and higher efficiency to the system. There are different choices for fuel selection in hybrid systems. The reason why biomass is examined among these is that it decreases the depletion of energy carriers and reduces the environmental impact.

Texto completo
Resumen

Numerical investigations of an optimized thin airfoil with a passive and an active flow control device (riblets and rotary cylinder) have been performed. The objectives of the thesis were to investigate the tip vortices reduction using riblets and decrease in flow separation, using a rotary cylinder for improved lift-to-drag ratio. The investigations has application potentials in improving performances of Micro Air Vehicles (MAVs). The airfoil has a chord length of 19.66 cm and a span of 25 cm. with the free stream mean velocity was set at 20 m/s. The Reynolds number was calculated as 3 × 10 4. Investigations with base model of the airfoil have shown flow separation at approximately 85% chord length at an angle of attack of 17 degrees. For investigation using passive flow control device, i.e. riblets, investigations were performed for different radial sizes but at a fixed location. It was found that with 1 mm radial size riblet, the tip vortices were reduced by approximately 95%, as compared to the baseline model. Although negligible lift-to-drag improvement was seen, a faster dissipation rate in turbulent kinetic energy was observed. Furthermore, investigations were carried out using the active flow control device. The rotary cylinder with a 0.51 cm in diameter was placed slightly downstream of the location of flow separation, i.e. at x/c = 0.848. Investigations were performed at different cylinder's rotations, corresponding to different tangential velocities of being higher than, equal to and less than the free stream mean velocity. Results have shown approximately 10% improvement in lift to drag ratio when the tangential velocity is near the free stream mean velocity. Further investigation may include usage of the riblets and the rotary cylinder combined, to increase the stability as well as the lift-to-drag ratio of the MAVs.

Resumen
Experimental observations of liquid microchannel flow are reviewed and results of computer experiments concerning channel entrance, wall slip, non-Newtonian fluid, surface roughness, viscous dissipation and flow instability effects on the friction factor are discussed Specifically, based on numerical friction factor analyses, the entrance effect should be taken into account for any microfluidic system. It is a function of channel length, aspect ratio and the Reynolds number. Non-Newtonian fluid flow effects are expected to be important for polymeric liquids and dense particle suspension flows. The wall-slip effect is negligible for liquid flows. For relatively low Reynolds numbers, i.e., Re > 1,200, onset to instabilities may have to be considered because of possible geometric non-uniformities, including a contraction and/or bend at the microchannel inlet as well as substantial surface roughness. Significant roughness effects, described with a new porous medium layer (PML) model, are a function of the Darcy number, the Reynolds number and cross-sectional configurations. This model was applied to micro-scale liquid flows in straight channels, tubes and rotating cylinders, and validated with experimental data sets. In contrast to published models, PML model simulations yield both an increase and decrease of the friction factor depending on the Darcy number. Viscous dissipation in microchannels is a strong function of the channel aspect ratio, Reynolds number, Eckert number, Prandtl number, and conduit hydraulic diameter. Specifically, viscous dissipation effects are quite important for fluids with low specific heat capacities and high viscosities, even for very low Reynolds numbers, i.e., ReD < 1. The viscous dissipation effect was found to decrease as the fluid temperature increases. As the aspect ratio deviates from unity, the viscous dissipation effect increases. It was found that ignoring the viscous dissipation effect could ultimately affect friction factor measurements for flows in micro-conduits. This could imply a significant amount of viscous heat generation and, for example, may diminish a projected micro-heat-exchanger performance.

Resumen
To aid FE simulation for forming micro-components, an integrated approach is proposed to generate virtual microstructure for micro-mechanics modelling. Based on Voronoi tessellation and the probability theory, a VGRAIN system is created for the generation of grains and grain boundaries for micro-materials. The input data of the system are physical parameters of a material, including average, minimum and maximum grain sizes. Numerical procedures have been established to link the physical parameters of a material to the control variable in a gamma distribution equation and a method has been developed to solve the probability equation. These are the basis for the development of the VGRAIN system, which can be used to generate different grain structures and shapes that follow a certain pattern according to the probability theory. Statistical analyses have been carried out to investigate the distribution of generated virtual grains. The generated virtual microstructure is then implemented in the commercial FE code, ABAQUS, for mesh generation and micro-mechanics analysis using crystal plasticity equations for FCC materials. The crystal plasticity model is implemented in the commercial FE code, ABAQUS, through the used-defined subroutine, UMAT. FE analyses have been carried out to investigate size effects and localised necking encountered in micro-forming processes.

Resumen
Pressure-sensitive paint (PSP) is an optical measurement technique based on the photo-chemical reaction between oxygen and luminescent molecules, and has potential as a diagnostic tool for pressure measurement in the high Knudsen number regime. However, the application of PSP to micro flow measurement is not straightforward, because conventional PSPs are too thick owing to their polymer binder. In our previous work, we fabricated pressure-sensitive molecular film (PSMF) by using the Langmuir-Blodgett (LB) technique. In this study, we investigated the temperature dependency of Pt(II) Mesoporphyrin IX (PtMP) based PSMF, and found that the temperature dependency of the pressure sensitivity is very small. Moreover, we have applied PSMF to the pressure measurement of micro gas flows through the 170μm width micro channel and the 100μm width micro nozzle, and the pressure distributions were successfully obtained.

Arazi, Tzahi, Vivian Irish y Asaph Aharoni. Micro RNA Targeted Transcription Factors for Fruit Quality Improvement. United States Department of Agriculture, julio de 2008. http://dx.doi.org/10.32747/2008.7592651.bard.

Resumen
Fruits are unique to flowering plants and represent an important component of human and animal diets. Development and maturation of tomato fruit is a well-programmed process, and yet, only a limited number of factors involved in its regulation have been characterized. Micro-RNAs (miRNAs) are small, endogenous RNAs that regulate gene expression in animals and plants. Plant miRNAs have a vital role in the generation of plant forms through post-transcriptional regulation of the accumulation of developmental regulators, especially transcription factors. Recently, we and others have demonstrated that miRNAs and other type of small RNAs are expressed in tomato fruit, and target putative transcription factors during its development and maturation. The original objectives of the approved proposal were: 1. To identify fruit miRNA transcription factor target genes through a bioinformatic approach. 2. To identify fruit miRNA transcription factor target genes up-regulated in tomato Dicer-like 1 silenced fruit. 3. To establish the biological functions of selected transcription factors and examine their utility for improving fleshy fruit quality trait. This project was approved by BARD as a feasibility study to allow initial experiments to peruse objective 2 as described above in order to provide initial evidence that miRNAs do play a role in fruit development. The approach planned to achieve objective 2, namely to identify miRNA transcription factor targets was to clone and silence the expression of a tomato DCL1 homolog in different stages of fruit development and examine alterations to gene expression in such a fruit in order to identify pathways and target genes that are regulated by miRNA via DCL1. In parallel, we characterized two transcription factors that are regulated by miRNAs in the fruit. We report here on the cloning of tomato DCL1 homolog, characterization of its expression in fruit flesh and peel of wild type and ripening mutants and generation of transgenic plants that silence SlDCL1 specifically in the fruit. Our results suggest that the tomato homolog of DCL1, which is the major plant enzyme involved in miRNA biogenesis, is present in fruit flesh and peel and differentially expressed during various stages of fruit development. In addition, its expression is altered in ripening mutants. We also report on the cloning and expression analysis of Sl_SBP and Sl_ARF transcription factors, which serve as targets of miR157 and miR160, respectively. Our data suggest that Sl_SBP levels are highest during fruit ripening supporting a role for this gene in that process. On the other hand Sl_ARF is strongly expressed in green fruit up to breaker indicating a role for that gene at preripening stage which is consistent with preliminary in_situ analyses that suggest expression in ovules of immature green fruit. The results of this feasibility study together with our previous results that miRNAs are expressed in the fruit indeed provide initial evidence that these regulators and their targets play roles in fruit development and ripening. These genes are expected to provide novel means for genetic improvement of tomato fleshy fruit.

Resumen
Novel approaches are needed to support the creation of more open, inclusive, and self-sustaining R&I ecosystems in healthcare. This study analysed 3 European regions (Murcia ES), (Örebro SE), and (Republic of Cyprus CY), incorporating complementary approaches from Responsible Research and Innovation (RRI) and Research and Innovation Smart Specialisation Strategy (RIS3). The exercise entailed the identification of healthcare and innovation stakeholders and the characterisation of the policy landscape in each territory. Moreover, the strengths of the regional knowledge base was analysed by measuring the Revealed Comparative Advantage (RCA) indicator based on relatedness measurement, and by using micro-level fields analyses of scientific publications. This methodology allowed us to identify the fields and topics (strengths) that provide opportunities for innovation processes. Additional identification of social needs in the three territories showed profound differences regarding the alignment of the selected needs with respect to the regions’ capabilities. The results suggest that a timely direct interaction with territorial stakeholders can help in selecting the most promising innovation priorities that are based on local needs and knowledge. The process of interaction requires early engagement to support territorial ownership and is further reinforced by RRI policies in place.

Resumen
Empirical analyses that rely on micro-level panel data have found that exporters are generally less pollutant than non-exporters. While alternative explanations have been proposed, firm level data has not been used to examine the role of destination markets behind the relationship between exports and pollution. In this paper we argue that because consumers in high-income countries have higher valuations for clean environments than consumers in developing countries, exporters targeting high-income countries are more likely to improve their environmental outcomes than exporters targeting destinations where valuations for the environment are not high. Using a panel of firm-level data from Chile we find support to this hypothesis. A 10 percentage point increase in the share of exports to high-income countries is associated with a reduction in CO2 pollution intensity of about 16%. The results have important implications for firms in developing countries aiming to target high-income markets.
