Abstract We examined the effects of interleukin-3 (IL-3) and interleukin-4 (IL- 4) on connective tissue-type mast cells (CTMC) purified from murine peritoneal cells. Although both factors failed to induce extensive proliferation of CTMC, they stimulated CTMC proliferation synergistically in a dose-dependent manner. Pretreatment of CTMC with IL-3 and/or IL-4 indicated that the sustained presence of both factors was required for the development of type 1 mast cell colonies. The delayed addition of IL-3 to cultures of purified CTMC with IL-4 induced no colony formation, while the delayed addition of IL-4 to cultures with IL-3, even on day 28 of culture, induced type 1 colony formation. In replating type 1 colonies induced by IL-3 and IL-4 to secondary cultures with IL-3 alone, few secondary colonies developed. However, the delayed addition of IL-4 to the secondary culture induced many type 1 colonies. The purified CTMC cultured with IL-3 retained the morphological and cytochemical characteristics of CTMC, as well as proliferative ability. These observations indicate that IL-3 supports the survival of CTMC in methylcellulose culture and that IL-4 triggers and supports CTMC proliferation synergistically with IL-3. The serum- free culture of purified CTMC and the culture of single CTMC demonstrated that the synergistic effect of IL-3 and IL-4 on colony growth and the surviving effect of IL-3 on CTMC require no influence from accessory cells or other humoral factors.

Abstract Regulatory T cells (Treg) are proposed to be involved in fetal tolerance induction. However, the precise mechanisms underlying their generation and function are still not defined. Recently, we proved that the pregnancy hormone human Chorionic Gonadotropin (hCG) efficiently attracts human Treg to trophoblasts favoring a local Treg accumulation. Here we analyzed whether hCG is also involved in Treg generation and activity. Naïve T cells were isolated from blood of pregnant women and co-cultured with either hCG-producing trophoblasts (JEG-3, primary cells) or non-hCG-producing trophoblasts (HTR8, Swan71) and keratinocytes (HaCat). To confirm hCG specificity, we either blocked hCG in JEG-3 co-cultures or used urine-purified or recombinant hCG as culture supplements. Treg induction was then assessed by the expression of specific Treg markers. Furthermore suppressive function of hCG-treated naïve T cells was evaluated in a mixed leukocyte reaction. Co-culture of naïve T cells with JEG-3, primary trophoblasts or supplemented hCG resulted in a statistically significant increase in the expression of specific Treg markers as compared to co-cultures with HTR8, Swan71 or HaCat cells. Moreover, blockage of hCG in JEG-3 co-cultures impaired the up-regulation of Treg markers. Interestingly, we further confirmed an increased suppressive activity of naïve T cells after hCG treatment. Our results strongly suggest a key role for hCG in Treg generation and induction of suppressive activity.

In the field of in vitro liver disease models, decellularised organ scaffolds maintain the original biomechanical and biological properties of the extracellular matrix and are established supports for in vitro cell culture. However, tissue engineering approaches based on whole organ decellularized scaffolds are hampered by the scarcity of appropriate bioreactors that provide controlled 3D culture conditions. Novel specific bioreactors are needed to support long-term culture of bioengineered constructs allowing non-invasive longitudinal monitoring. Here, we designed and validated a specific bioreactor for long-term 3D culture of whole liver constructs. Whole liver scaffolds were generated by perfusion decellularisation of rat livers. Scaffolds were seeded with Luc+HepG2 and primary human hepatocytes and cultured in static or dynamic conditions using the custom-made bioreactor. The bioreactor included a syringe pump, for continuous unidirectional flow, and a circuit built to allow non-invasive monitoring of culture parameters and media sampling. The bioreactor allowed non-invasive analysis of cell viability, distribution, and function of Luc+HepG2-bioengineered livers cultured for up to 11 days. Constructs cultured in dynamic conditions in the bioreactor showed significantly higher cell viability, measured with bioluminescence, distribution, and functionality (determined by albumin production and expression of CYP enzymes) in comparison to static culture conditions. Finally, our bioreactor supports primary human hepatocyte viability and function for up to 30 days, when seeded in the whole liver scaffolds. Overall, our novel bioreactor is capable of supporting cell survival and metabolism and is suitable for liver tissue engineering for the development of 3D liver disease models.

Abstract [Background] Myelodysplastic syndrome is an intractable disorder characterized by ineffective hematopoiesis. Although allogeneic hematopoietic stem cell transplantation is the only curative therapy for eligible patients, hematopoiesis-supportive pharmacotherapy is practically important for transplant-ineligible patients to overcome transfusion dependency and infections. Vitamin K2 (VK2, menatetrenone) is a drug used to aim at improvement of hematopoiesis in MDS patients (Leukemia 14: 1156, 2000). However, the exact mechanism how VK2 improves hematopoiesis remains largely unknown. It was reported that VK2 induces MDS cells to undergo apoptosis (Leukemia 13: 1399, 1999). Here, we investigated our hypothesis that VK2 exerts its hematopoiesis-supportive effects through acting on mesenchymal stem/stromal cells (BM-MSCs) in the bone marrow microenvironment. [Methods] Normal bone marrow (BM) samples from healthy adult volunteers were purchased from AllCells (Emeryville, CA). BM-CD34+ cells were isolated from BM-mononuclear cells using anti-CD34 immunomagnetic microbeads (Miltenyi Biotec, Bergisch Gladbach, Germany). Human BM-MSCs were isolated according to our previously published methods (Stem Cells 32:2245, 2014). In co-culture experiments, BM-MSCs with or without VK2 treatment were seeded on a 24-well culture plate. BM-CD34+ cells were applied on the MSC-grown plate and co-cultured in SFEM (StemCell Technologies, Vancouver, Canada) supplemented with 100 ng/mL SCF, 100 ng/mL Flt-3 ligand, 50 ng/mL TPO and 20 ng/mL IL-3. After 10 days of co-culture, the number and surface marker expression of the expanded hematopoietic cells were examined by flow cytometric analysis. [Results] We first tested the direct effect of VK2 on BM-CD34+ cells. BM-CD34+ cells were treated with VK2 at various concentrations ranged from 0 µM to 10 µM for 24 hours and then cultured in SFEM in combinations with cytokines. Surprisingly, viable hematopoietic cells were hardly detected in the expansion culture of BM-CD34+ cells treated with 10 µM VK2. Even with 1 µM treatment, the number of CD45+ cells was decreased, as compared to that of expansion culture of untreated BM-CD34+ cells. The apoptosis analysis showed that the percentage of AnnexinV+ PI+ cells in the expanded hematopoietic cells is increased by VK2 treatment. We next examined the effect of VK2 on the hematopoiesis-supportive capability of BM-MSCs. BM-MSCs were pretreated with VK2 at various concentrations and then co-cultured with BM-CD34+ cells. The numbers of CD34+ cells and CD45+ cells were increased in a VK2 dose-dependent manner. These results demonstrated that VK2 shows different effects on distinct stem/progenitor cells: the induction of apoptosis in BM-CD34+ cells and the enhancement of hematopoiesis-supportive capability of BM-MSCs. We then investigated whether apoptosis-related cell death of BM-CD34+ cells by VK2 treatment is ameliorated in the presence of BM-MSCs. Both BM-CD34+ cells and BM-MSCs were treated with VK2 for 24 hours, and then co-cultured. The number of CD34+ cells was not decreased significantly in contrast to its severe decrease in single culture of VK2-treated BM-CD34+ cells. We further analyzed the effect of VK2 on BM-MSCs. Subpopulation analysis in co-culture of CD34+ cells with VK2-treated BM-MSCs showed that the expansion efficacy of CD34+CD38+ cells is higher in comparison to that of CD34+CD38- cells. In addition, the percentages of CD34-CD33+ cells and CD34-CD13+ cells were higher than those in co-cultures with untreated BM-MSCs. Therefore, VK2-treated BM-MSCs supported the expanded CD34+ cells to skew their phenotype toward myeloid lineage. The presence of a transwell in the co-culture system was unrelated to the expansion pattern of CD34+ cells, which suggested the involvement of soluble factors with respect to the underlining mechanism. We therefore compared the levels of hematopoiesis-supporting cytokine mRNA expression in VK2-treated and untreated BM-MSCs: VK2-treated BM-MSCs showed lower expression of CXCL12/SDF-1 mRNA and a trend toward higher expression of GM-CSF mRNA. [Summary] VK2 acted on BM-MSCs to support their ability to enhance expansion and myeloid differentiation of BM-CD34+ cells probably via altered GM-CSF and CXCL12/SDF-1 expression in MSCs. These findings may help to identify the mechanisms of therapeutic effects of VK2 in patients with MDS (Figure). Disclosures No relevant conflicts of interest to declare.

Les cellules adhérentes, dont les cellules souches, sont très prometteuses pour de nombreuses applications dans le domaine des biotechnologies. Toutefois, leur culture représente un défi puisque les méthodes enzymatiques et mécaniques, couramment utilisées pour l’étape de détachement du support de culture, présentent des inconvénients majeurs. Le but de ce travail de thèse a été de développer un support pour la culture de cellules adhérentes permettant leur détachement par modification de la température. Pour cela, nous avons produit des échantillons thermo-associatifs de xyloglucane, un polysaccharide naturel, par réaction avec une enzyme, la ß-galactosidase. Les échantillons obtenus ont été caractérisés par rhéologie, viscosimètrie, diffusion de la lumière et chromatographie par perméation de gel. Nous nous sommes aussi intéressés à l’évaluation de méthodes de stérilisation efficaces capables de préserver les propriétés du polymère. De plus, afin de rendre ce polymère bioadhésif, nous avons étudié son activation et sa fonctionnalisation par un peptide contenant le motif arginine-glycine-aspartate (RGD). Nous avons montré que des cellules modèles A375 surexprimant le récepteur pour le RGD sont capables d’adhérer et de proliférer à 37°C sur des films formés à partir de xyloglucane modifié par du RGD. Leur détachement est possible à température ambiante. L'utilisation de ce nouveau support pour la culture de cellules souches embryonnaires humaines, la production d’un système pour la libération contrôlée de facteurs de croissance ainsi que la conception de billes de taille micrométrique à base de xyloglucane font partie des perspectives de cette thèse
Adherent cells, including stem cells, hold great promise for many applications in biotechnology. However, cell detachment from standard culture surfaces remains a challenging task since both commonly used enzymatic and mechanical methods have major drawbacks. The aim of my PhD work was to develop a thermoresponsive culture surface supporting cell attachment and survival while enabling a temperature-assisted cell detachment. In order to achieve this goal, thermoresponsive xyloglucan was initially produced by partial galactose removal after reaction with the β-galactosidase enzyme. Samples were characterized by rheology, viscosimetry, light scattering analysis and size-exclusion chromatography. We were also interested in evaluating sterilization methods and their effect on the properties of the polymer. Additionally, in order to obtain a bioadhesive polymer from partially degalactosylated xyloglucan, we studied its functionalization with a peptide containing the arginine-glycine-aspartate (RGD) groupment motif. We have shown that A375 model cells overexpressing the RGD receptor were able to adhere and proliferate at 37 °C on xyloglucan-derived films grafted with RGD and their detachment at room temperature was also demonstrated. The culture of human embryonic stem cells, as well as the introduction of a controlled release system for growth factors and the development of thermoresponsive beads for cell culture comprise the perspectives of this thesis

Les propriétés de rétention et de circulation de l'eau et de l'oxygène dans les supports de culture présentent de fortes particularités qui sont liées à un volume réduit de substrat (pot, conteneur), dans lequel les biodisponibilités hydrique et gazeuse fluctuent fortement et rapidement au cours de la journée. Afin d'optimiser les apports d'intrants aux besoins de la plante, tout en limitant les rejets vers l'environnement, il est nécessaire d'améliorer la compréhension des processus de transfert de matière dans les substrats au voisinage des racines. Dans cette optique, nous nous sommes tout d'abord attachés à mesurer et à comprendre l'impact des propriétés physiques de deux matériaux organiques modèles (tourbes blondes et écorces de pin compostées) sur les processus de transfert de matière, au cours d'un cycle de dessiccation-réhumectation. Cette étude préalable, a permis de proposer un modèle de fonctionnement hydrostructural des matériaux organiques. Nous avons pu notamment mettre en évidence que l'hystérèse des propriétés de surface des matériaux organiques (variation de la mouillabilité en fonction de l'état hydrique) pouvait expliquer l'hystérèse des caractéristiques hydrique et hydrodynamique de ces milieux poreux. La déformation des matériaux va également influencer les propriétés de rétention et de transfert d'eau et d'air dans le milieu. Ces modifications, qui se déroulent dans les états hydriques les plus forts, vont faire intervenir des processus hydrostructuraux différents suivant que l'on s'intéresse à la tourbe (déformation élastique totalement réversible) ou aux écorces (déformation plastique partiellement réversible). Nous avons pu également définir des gammes “optimales” de potentiel hydrique ou de teneurs en eau (où les flux d'eau et d'oxygène dans ces deux substrats sont très élevés) bien différentes des seuils empiriques de -1 kPa et -10 kPa, encore aujourd'hui utilisés pour la gestion de l'irrigation dans les cultures en pots et conteneurs. Afin de représenter l'effet des propriétés préalablement définies sur les biodisponibilités en eau et en oxygène reliées aux besoins de la plante, nous avons ensuite intégré ces propriétés dans un modèle monodimensionnel de transfert couplés d'eau et d'oxygène au voisinage des racines (fonction puits racinaire) et à l'échelle journalière. Cette approche modélisatrice a permis de mettre en évidence qu'il était difficile de réunir sur une journée de culture, et sur une gamme apparemment optimale de potentiel hydrique, en même temps des conditions de teneurs en eau et en oxygène non limitantes pour la racine. Ces résultats ont été obtenus quels que soient le substrat considéré et les états hydriques initiaux fixés
Distribution and movement of liquids and gases in growing media present high specificity due to the limited volume of susbtrate (for roots fonctioning) in which water and oxygen availability highly fluctuate over a short period of time. In order to optimize management of fertigation and for subsequent plant growth in soilless culture production, it is still necessary to improve our knowledge of transfer properties (water and oxygen) at the substrate-root interface. In this context, we first precisely studied the influence of the physical properties of two organic materials model (Sphagnum peat and composted pine barks) on the dynamic of water and oxygen, during a drying-wetting cycle. A hydrostructural model was proposed for these two organic materials. We showed that hysteresis phenomena observed in the surface properties (evolution of wettability related to water potential) could be associated with hysteresis phenomena observed in the hydraulic characteristics of these porous media. The deformation of materials also influence retention and transfer properties of water and air in the substrates. Modifications of the solid phase, which occured near saturation, underline different hydrostructural behaviour depending on whether peat (elastic, reversible deformation) or barks (plastic, partly irreversible deformation) is considered. "Not-limiting" range of water potential (corresponding to high oxygen and water flows in substrates) were determined, and results obtained are quite different from the empirical thresholds of -1 kPa and -10 kPa, still used for the management of fertigation in soilless culture production. In order to represent the effect of all properties beforehand define on oxygen and water availability related to the physiological needs of the plant, we embed these properties in a one-dimension transfer coupled model of water and oxygen in the root vicinity and on a one-day time scale. If one replaces in the "not-limiting" range of water potential, our model underline that it is difficult to maintain during one day of culture, at the same time, water and oxygen content conditions not limiting for the roots. These results were obtained whatever the substrate and the water content considered

Corruption and unethical management is a legitimate global economic concern as it can have a direct and substantial impact on the longevity and the economic success of an organisation, an industry and a country. As a result of individuals having more readily available access to information, much attention has been given to unethical behaviour and organisational ethical violations over the last decade. Recent events have indicated that business ethics is an organisational concern with mammoth implications for business. For example, Esterhuyse (1999, p. 27) reports that South Africa has lost astronomical amounts of money due to office or white-collar crime. Organisations’ attempts to become globally competitive will be hampered by the behaviour of employees who are unethical at work. Therefore, it is imperative that organisations implement measures to increase ethical awareness and behaviour in their employees. This research study deals with business ethics in the automotive cluster of the Eastern Cape Province and proposes a model that can assist an organisation in improving its ethical culture. The main question that this research study addressed was: To what extent do the strategies of human resource departments contribute to establishing and maintaining an ethical organisational culture? To answer the above question it was necessary to address the most universal characteristics of ethical organisations. To this end the role of the human resource department in attempting to develop and sustain an ethical organisational culture is discussed. Thereafter, various ethical models are outlined and evaluated. Lastly, the proposed ethical model for establishing an ethical organisational culture is presented. Based on the theoretical findings of the literature survey which outlined the characteristics of ethical organisations and the interventions required to improve the ethical functioning of an organisation, a questionnaire was developed and distributed to organisations within the automotive cluster in the Eastern Cape Province. The empirical results obtained from the survey indicated dominant consensus regarding the model (see Chapter Four). The main findings from this research are that 74.7 per cent of organisations that participated in the empirical study had implemented a code of ethics. However, the majority of these organisations had not implemented the identified critical and optional interventions (see to Chapter Four) required to operate as an ethical organisation. The study also revealed that 49.4 per cent of respondents believed that the human resource manager is responsible for organising and coordinating an ethical initiative within the organisation. Respondents in this study stated that the benefits of operating ethically are the improved financial position of the organisation (76.5 per cent), the enhanced morale of employees (95.3 per cent), positive stakeholder perception (93 per cent), better long-term strategic sustainability (94.3 per cent) and superior social responsibility (85.9 per cent).

En culture hors-sol, une gestion raisonnée de l’eau est nécessaire pour augmenter le rendement d’une culture. Les propriétés de rétention en eau et en air des substrats horticoles sont étroitement liées à la morphologie des particules, elle conditionne leur arrangement duquel se dessine un espace poral composant au moins 85% du volume. La morphologie détaillée des particules n'a jamais été réellement étudié pour les substrats horticoles, en partie parce que l’analyse est complexe, en raison de la grande diversité des tailles et des formes des particules. Seul le tamisage a été utilisé pour caractériser les particules, cependant cette méthode rencontre beaucoup de limites (imprécise, peu informative, pas adaptée à toutes formes de particules). Pour détailler les liens entre propriétés physiques et morphologie des particules, les recherches présentées reposent sur l’utilisation de l’analyse d’images dynamique, offrant des résultats plus précis et détaillés. Diverses mesures de répartitions granulométriques et de propriétés physiques sur une grande diversité de matériaux, ont été effectuées. Les résultats révèlent une très grande diversité des tailles et des formes des particules au sein de chaque matériau. La morphologie des particules peut être résumée par leur circularité et leur longueur. Plus la taille des particules est petite, plus le substrat est composé de pores fins, plus retient d’eau, et inversement moins d’air. Aussi l’évolution de la structure du matériau est impactée par les particules fines. Finalement, la longueur moyenne des particules est un bon estimateur de ses propriétés physiques. Ces travaux donnent des clés aux fabricants de supports de culture pour mieux designer leurs matières et encouragent à caractériser les propriétés physiques par l'étude de la morphologie des particules
In soilless culture, a wise management of water is necessary to increase the yield of a crop. The water and air retention properties of horticultural substrates are closely linked to the morphology of the particles, which determines their arrangement and from which a pore space is formed that makes up at least 85% of the volume. The detailed morphology of the particles has never been really studied for growing media, partly because the analysis is complex, due to the great diversity of particle sizes and shapes. Only sieving has been used to characterize the particles, however this method has many limitations (inaccurate, not very informative, not adapted to all particle shapes). In order to detail the links between physical properties and particle morphology, the presented research relies on the use of dynamic image analysis, offering more precise anddetailed results.Various measurements of particle size distributions and physical properties on a wide variety of materials have been performed. The results reveal a very large diversity of particle size and shape within each material. The morphology of the particles can be summarized by their circularity and length. The smaller the particle size, the more fine pores the growing media has, the more water it retains, and conversely the less air. Also, the evolution of the material structure is impacted by finer particles. Finally, the mean length of the particles is a good estimator of its physical properties. This work gives growing media manufacturers keys to better design their materials, and encourages to characterize the physical properties by studying particle morphology

« L’utilisation des séries judiciaires télévisuelles pour l’enseignement de l’anglais juridique : étude des séries américaines et anglaises comme support pédagogique. » Cette étude est le résultat d’un projet de recherche sur la possibilité d’exploiter les séries judiciaires anglaises et américaines comme outils pour l’enseignement de la culture et du langage juridiques anglo-saxons à des étudiants en droit. L’objectif étant essentiellement de comparer deux pays de même tradition juridique pour mettre en exergue leurs différences culturelles nationales. La base théorique de cette analyse se trouve dans le champ des cultures juridiques et dans les séries judiciaires ainsi que dans la méthode "Silent Way". Il s’agit de montrer comment ces programmes de télévision créent un environnement qui encourage les étudiants à acquérir une meilleure connaissance du système de common law ainsi que du langage juridique anglais, et ce de manière autonome et en déployant peu d’énergie. Une brève description d’une expérience visant à utiliser ce type de séries télévisées dans le contexte d’un enseignement universitaire d’une part et une étude menée auprès d’un certain nombre de professeurs d’anglais juridique en France d’autre part, ont permis de vérifier que l’utilisation de ces séries et de ces films comme supports pédagogiques suscitait un vif intérêt. Les données extraites des séries anglaises et américaines étudiées ici, ont été analysées avec une approche comparative empirique qui a permis de mettre en lumière des similitudes et des différences notamment dans les professions juridiques et dans les rituels des tribunaux de ces deux pays régis par la "common law"
< Using courtroom dramas in teaching legal English: studies of American and British series as pedagogical materials > is the result of a research project on the exploitability of British and American television procedurals as tools for teaching English legal language and culture to law students, especially with a view to comparing these two countries belonging to the same legal tradition and highlighting national cultural differences. The theoretical basis for this analysis resides in the field of legal cultures and legal series as well as the pedagogical approach of the "Silent Way" in order to show how these programmes create an environment that encourages students to acquire knowledge of common law culture and legal English in an autonomous and economic way. A brief description of an experience using such shows in the context of a university course and a survey conducted with a number of legal English teachers in France, confirmed a significant interest with regarding the use of series and films as teaching aids. The data found in the English and American series of the corpus studied here, is analysed through an empirical comparative approach which reveals similarities and differences with respect to such aspects as the legal professions and courtroom ritual in these two common law countries

La connaissance précise au fil du temps des propriétés physiques du milieu de culture d’un végétal est importante pour une gestion efficace de l'irrigation et de la fertilisation. Ce travail est consacré a l’évaluation des évolutions hydriques (rétention en eau), structurales (retrait/gonflement) et superficielles (mouillabilité) des matériaux organiques utilisés comme supports de culture pendant plusieurs cycles de dessiccation et ré-humectation. Un effort de développement expérimental important a porté sur la mise au point de méthodes permettant de mesurer simultanément et en continuité les variations de déformation volumique (retrait/gonflement) du massif et de ses propriétés de rétention en eau. Trois matériaux, tourbe blonde de sphaigne, tourbe noire et fibre de coco ont été testés avec des contraintes hydriques atteignant -32 kPa. Les courbes obtenues montrent une évolution importante du volume du massif au cours du cycle de dessiccation et ré-humectation, les 2"’ et 3' Cycle sont répétitifs et superposables. L’intensité de la dessiccation appliquée a un effet important sur les propriétés de rétention en ré-humectation dans le cas des tourbes blondes de sphaigne ; il est peu perceptible pour la tourbe noire et la fibre de coco. Tous les matériaux testés montrent un caractère biporal très marqué avec une première porosité inter-grain ou inter-fibre se vidant autour de -lkPa et une porosité intra-grain plus variable en fonction des matériaux, de -15kPa pour la tourbe blonde a -40kPa pour la tourbe noire. Le caractère hydrophobe des matériaux au cours de la dessiccation a été évalué avec deux méthodes : ascension capillaire et goutte posée. Une approche méthodologique a permis de mettre en correspondance ces deux approches et d’expliquer leurs différences. Pour tous les matériaux, la mouillabilité varie surtout en fonction de l’humidité de matériau. Le retour a un caractère hydrophile avec la ré-humectation est variable et fonction des matériaux, rapide et réversible dans le cas de la fibre de coco, il est plus lent dans le cas des tourbes. Si les phénomènes dits « de bouteilles d’encre » restent probablement prépondérants pour expliquer l’hystérèse des propriétés de rétention dans les états les plus humides, l’utilisation d’un modelé biporal de type van Genuchten et introduisant un angle de contact en ré-humectation a permis de montrer que dans les dessiccations les plus poussées, l ' hydrophobie peut expliquer la plus grande partie des phénomènes d’hystérèse
The precise knowledge over time of physical properties of a plant roots environment is important for the effective management of irrigation and fertilization. This work is devoted to the assessment of the variations in water retention, shrinkage/swelling and wettability of organic materials used as growing media during several drying and resetting cycles. An important effort is done to develop the methods used to measure simultaneously and continuously the changes in volumetric deformation of the massif (shrinkage/swelling) and its water retention properties. Three materials, sphagnum peat, black peat and coco coir were tested with suction up to -32 kPa. The curves obtained show an important evolution during the first drying and rewetting cycle, however the second and third cycle is repetitive and superimposed. The drying intensity has the impact on the irreversibility of water retention measured on peat, however it is not very perceptible with black peat and coco coir. All materials tested showed a double porosities character with a porosity inter-fiber or inter-grain emptied around -1 kPa and another porosity intra-grain with the air entry pressure variable depending on materials, -15 kPa for blond peat and -40 kPa for black peat. The water repellency of material during the drying was assessed with two methods: sessile drop and capillary rising methods. This methodological approach allows finding out their correspondence and difference. The variation of wettability depends mainly on the humidity of material. If the effect of “ink bottle” is probably crucial in explaining the hysteresis of water retention properties in the most wet states, using a bimodal model of van Genuchten introduced a contact angle in resetting has shown the water repellency can explain the hysteresis in the case of more intense drying suction

AbstractAs a result of social, technological and economic changes, there is a need to transform the currently dominant linear economic paradigm into one of circular economy. This transformation requires the implementation of effective green innovations that economically and environmentally encourage their main potential promoters: companies and managers. The objective of this research is to verify whether, as in other industries, green innovation has positive effects on the firms’ corporate performance in the accommodation industry, evaluating whether the organizational culture enhances the success of this type of innovation. Proposals developed have been contrasted with an empirical analysis on a sample of 202 tourist accommodation on the Spanish coast, especially hotels, using the Partial Least Squares (PLS-SEM) technique. The results obtained support the positive effect of green innovation on corporate performance, as well as the importance of the robustness of an organizational culture that supports the exploitation of this type of innovation in terms of results. The conclusions that are derived are especially relevant since they highlight the importance of a culture based on commitment and innovation that favors the implementation of the circular economy model in the tourism sector.

Fortresses are architectural pearls, cultural sites, event locations, experience places and memorials, mostly situated at breath-taking places on mountains, rivers or in the under-ground. Fortresses are monuments of common European history, they mirror the past into the present, connect cultures and offer deep insights into the historical conflicts. Fortified monuments are part of what makes Europe unique and attractive. This cultural heritage has to be preserved and made accessible for the culture tourism at the same time. The Iberian fortified heritage has big potential for new culture touristic topics and travel routes away from mass tourism. Therefore, cultural routes are a useful instrument. The European Culture Route Fortified Monuments –FORTE CULTURA®– is the European umbrella brand for fortress tourism. It offers useful instruments for international marketing of fortified monuments. The implementation of the attractive architectura militaris of the Iberian Peninsula into the culture route FORTE CULTURA® makes it possible to network this culture asset touristically, make it visible and experienceable on international tourism markets and market it Europe-wide. By implementing a new touristic regional brand “FORTE CULTURA – Iberian Fortified Heritage” the qualified culture tourism will be addressed. This supports a balance between over and under presented monuments and extends the sphere of activity of local actors onto whole Europe.

Abstract The Hydrodynamic Focusing Bioreactor (HDFB) developed by NASA at the Johnson Space Center provides a unique hydrofocusing capability that simultaneously enables a low-shear culture environment and a unique hydrofocusing-based “herding” of suspended cells, cell aggregates, and air bubbles. The HDFB is a rotating dome-shaped cell culture vessel with a centrally located sampling port and an internal rotating viscous spinner attached to a rotating base. The vessel and viscous spinner can rotate at different speeds and in either the same or different directions. Adjusting the differential rotation rate between the vessel and spinner results in a controllable hydrodynamic focusing force. The resultant hydrodynamic force suspends the cells in a low-shear fluid environment that supports the formation of delicate three-dimensional tissue assemblies. Both suspension and anchorage-dependent cells have been successfully cultured.

Анотація:

The Tripletail, Lobotes surinamensis, is a pelagic fish found in tropical and sub-tropical waters of all oceans. Tripletails are often associated with floating debris and make frequent incursions in bays and estuaries where they are targeted by recreational fishermen. In Mississippi waters the species is typically present during the late spring and summer season that also correspond to the period of sexual maturation and spawning (Brown-Peterson and Franks 2001). Tripletail is appreciated as a gamefish but is also prized for its flesh of superior quality. The fast growth rate of juveniles in captivity documented by Franks et al. (2001) and the excellent quality of Tripletail flesh both contribute to the potential of this species for marine aquaculture. In addition, the production of cultured juveniles would be precious to develop a better understanding of the biology, early life history and habitat use of Tripletail larvae and juveniles, a topic largely undocumented to date, through experimental releases and controlled studies. The culture of tripletail thus supports the Tidelands Trust Fund Program through improved conservation of natural resources, potential enhancement of fisheries productivity and potential development of a new economic activity on the Gulf coast producing tripletail via aquaculture. The Objective of this project was to initiate development of methods and techniques needed to spawn captive held tripletail broodfish and raise their offspring to evaluate their growth and development in captivity. In this report we will present the results of studies aiming to develop methods and protocols for captive spawning of tripletail and the first data obtained on the early development of tripletail larvae. A major issue that was encountered with tripletail broodstock development during the project lied in the difficulties associated with identifying the sex of adults caught in the wild and candidates for being incorporated in mating sets for spawning. This issue was addressed during the course of the project by examining the potential of a non-lethal method of hormonal sexing. The results of these preliminary investigations are presented in the third part of this report. All protocols used in the project were determined with the guidance of the Institutional Animal Care and Use Committee (IACUC) of the University of Southern Mississippi (USM IACUC protocol number 10100108).

Objectives were to further characterize activity spectra of dairy propionibacteria bacteriocins, jenseniin G and propionicin PLG-1, purify them, examine the role of cell walls in resistance, examine their interactions with cytoplasmic membrane, explain producer immunity, and clone the responsible genes. Inhibitory spectra of both bacteriocins were further characterized. Propionicin was most effective in controlling Gram-positive, rather than Gram-negative organisms; it controlled growth of sensitive cells both in a culture medium and a model food system. Jenseniin inhibited yogurt cultures and may help prevent yogurt over-acidification. Both were active against botulinal spores; jenseniin was sporostatic; propionicin was sporicidal. Jenseniin was produced in broth culture, was stable to pH and temperature extremes, and was purified. Its molecular mass (3649 Da) and partial amino acid composition (74%) were determined. A blocked jenseniin N-terminus prevented sequencing. Methods to produce propionicin in liquid culture were improved, and large scale culture protocols to yield high titers were developed. Methods to detect and quantify propionicin activity were optimized and standardized. Stability of partially purified propionicin was demonstrated and an improved purification scheme was developed. Purified propionicin had a 9328-Da molecular mass, contained 99 amino acids, and was significantly hydrophobic; ten N-terminal amino acids were identified. Propionicin and Jenseniin interacted with cytoplasmic membranes; resistance of insensitive species was cell wall-related. Propionicin and jenseniin acted similarly; their mode of action appeared to differ from nisin. Spontaneous jenseniin-resistant mutants were resistant to propionicin but nisin-sensitive. The basis for producer immunity was not resolved. Although bacteriocin genes were not cloned, a jenseniin producer DNA clone bank and three possible vectors for cloning genes in propionibacteria were constructed. In addition, transposon Tn916 was conjugatively transferred to the propionicin producer from chromosomal and plasmid locations at transfer frequencies high enough to permit use of Tn916 for insertional mutagenesis or targeting genes in propionibacteria. The results provide information about the bacteriocins that further supports their usefulness as adjuncts to increase food safety and/or quality.

The arts do not exist in vacuum and cannot be valued in abstract ways; their value is how they make people feel, what they can empower people to do and how they interact with place to create legacy. This research presents insights across Australia and Aotearoa New Zealand about the value of arts and culture that may be factored into whole of government decision making to enable creative, vibrant, liveable and inclusive communities and nations. The COVID-19 pandemic has revealed a great deal about our societies, our collective wellbeing, and how urgent the choices we make now are for our futures. There has been a great deal of discussion – formally and informally – about the value of the arts in our lives at this time. Rightly, it has been pointed out that during this profound disruption entertainment has been a lifeline for many, and this argument serves to re-enforce what the public (and governments) already know about audience behaviours and the economic value of the arts and entertainment sectors. Wesley Enoch stated in The Saturday Paper, “[m]etrics for success are already skewing from qualitative to quantitative. In coming years, this will continue unabated, with impact measured by numbers of eyeballs engaged in transitory exposure or mass distraction rather than deep connection, community development and risk” (2020, 7). This disconnect between the impact of arts and culture on individuals and communities, and what is measured, will continue without leadership from the sector that involves more diverse voices and perspectives. In undertaking this research for Australia Council for the Arts and Manatū Taonga Ministry for Culture & Heritage, New Zealand, the agreed aims of this research are expressed as: 1. Significantly advance the understanding and approaches to design, development and implementation of assessment frameworks to gauge the value and impact of arts engagement with a focus on redefining evaluative practices to determine wellbeing, public value and social inclusion resulting from arts engagement in Australia and Aotearoa New Zealand. 2. Develop comprehensive, contemporary, rigorous new language frameworks to account for a multiplicity of understandings related to the value and impact of arts and culture across diverse communities. 3. Conduct sector analysis around understandings of markers of impact and value of arts engagement to identify success factors for broad government, policy, professional practitioner and community engagement. This research develops innovative conceptual understandings that can be used to assess the value and impact of arts and cultural engagement. The discussion shows how interaction with arts and culture creates, supports and extends factors such as public value, wellbeing, and social inclusion. The intersection of previously published research, and interviews with key informants including artists, peak arts organisations, gallery or museum staff, community cultural development organisations, funders and researchers, illuminates the differing perceptions about public value. The report proffers opportunities to develop a new discourse about what the arts contribute, how the contribution can be described, and what opportunities exist to assist the arts sector to communicate outcomes of arts engagement in Australia and Aotearoa New Zealand.
