Elucidating the composition of waxes is of utmost importance to explain their behavior in liquid oil structuring. The chemical components (hydrocarbons – HCs, free fatty acids – FFAs, free fatty alcohols – FALs and wax esters – WEs) of natural waxes were analyzed using HPLC–ELSD and GC–MS followed by evaluation of their oil structuring properties. The gel strength, including the average storage modulus and oscillation yield stress, displayed a negative correlation with FALs and a positive correlation with HCs, FFAs and WEs. The components dictating the gel strength are HCs, FFAs and WEs in a descending order of importance. The consistency of the oleogels increased with the increasing amount of FFAs and HCs and the decreasing amount of WEs and FALs. The presence of more WEs results in a strong but brittle gel with a high initial flow yield stress. We believe these results might be useful in selecting the right waxes to combine in certain fat-based food products. [less ▲]

Framed within the paradigm of New Public Management (NPM), structural reforms in the EU aimed at modernizing the public administrations of Member States (MSs) have long since been a priority area of the EU’s economic policy. Since the 1990s, these reforms have been sharply intensified across European countries with the declared purpose of enhancing economy, efficiency and effectiveness in their national public sectors’ organizations. In line with the European Commission’s recent research initiatives in search for novel quantitative data on NPM in the EU, this paper studies European parties’ NPM reform rhetoric. More specifically, it investigates the MSs’ institutional, economic and political context within which parties have declared their intention of reforming national administrative systems. Thus, it sheds light on the MSs’ domestic factors that are associated with the diffusion of the NPM values across the political discourse of EU’s national parties. [less ▲]

This book focuses on some of the main notions arising in graph theory, with an emphasis throughout on the possible applications of the theory and the fruitful links that exist with linear algebra. Commencing with basic notions such as connectedness, Eulerian, Hamiltonian and planar graphs, opens the way for a variety of applications. A short chapter is devoted to complexity theory, and after a presentation of the chromatic polynomial and Ramsey numbers, the book highlights the important interplay between graph theory and linear algebra. Perron-Frobenius theory is then presented. With rational generating functions and powers of the adjacency matrix, counting walks in a directed multigraph is a recurrent topic of the book and is studied in great detail. Google’s PageRank is then covered in the final chapter of the book. Every application of the theory is accompanied by fully worked examples and proofs, and supplemented by over 100 exercises throughout the book. This allows the student to gain a full and thorough understanding of advanced graph theory and its potential applications. [less ▲]

Producing enough food to meet the needs of a growing population has always been the greatest concern of food policy-makers around the world. Given the increasing attention to organic farming (OF), we conducted this study to investigate the main opportunities and challenges of the food production system of small-scale farmers in developing countries with an emphasis on their livelihoods. The study showed that the most significant advantages of OF are environmental protection and a higher resilience to environmental changes, increasing farmers' income and reducing external input cost, enhancing social capacity and increasing employment opportunities. A s well as enhancing food security primarily by increasing the food purchasing power of local people. However, the main challenges of this food production system include lower yields in comparison to conventional systems, difficulties with soil nutrient management, certification and market barriers, and the educational and research needs of small-holders. The paper concludes that even though OF might present some significant challenges to small-scale farmers, it could/should still be considered as a part of the solution and means of improving their livelihoods.

Les Trois-Evêchés ont été un terrain fertile pour les congrégations féminines aux 16e-18e siècles puisqu'ils ont vu la naissance de projets religieux conjuguée à une installation massive de « nouveaux ordres » nés ou réformés dans le sillage du concile de Trente. Fondées en Italie au début du 17e siècle, les annonciades célestes se sont implantées majoritairement sur la « dorsale catholique ». Au cœur de ce territoire de frontières, les Trois-Évêchés occupent une position géographique, politique et religieuse incontournable. Dans le cadre de cette journée d’études, il s’agira d’interroger les spécificités éventuelles des cinq monastères que les annonciades célestes firent édifier dans les Trois-Évêchés en les comparant à l’ensemble de la production architecturale de l’ordre en Europe aux 17e et 18e siècles. En allant plus loin, nous verrons comment les représentations mentales de ces édifices ont participé à la genèse de l’identité de l’ordre, notamment grâce aux sources écrites et iconographiques qui en témoignent.

An offshore wind farm covers a large maritime area and the site can be located close to traffic lanes of commercial and passenger ships, which may lead to possible collision events. The work presented in this paper aimed to understand both the crushing behavior and the nacelle dynamics of a predefined monopile offshore wind turbine when impacted by a ship. Another objective was to deeply investigate the influence of various parameters like ship impact velocity and location, wind direction, soil stiffness and deformability of the striking ship. First, nonlinear numerical simulations of ship - Offshore Wind Turbine (OWT) collisions have been carried out with a rigid striking ship for a better understanding of the OWT’s structural behaviour during collision. Different configurations for the wind turbine’s structure have been used in order to highlight the modifications in behaviour induced by changing the soil conditions or the loading scenario. The resulting resistant force and internal energies have been compared as well as the tower top (nacelle) displacements and accelerations. Then, another series of simulations have been performed with a deformable ship in order to investigate the influence of the deformability of the striking ship on the OWT’s behaviour. It is worth noting that all these numerical results will further serve to fix the hypotheses for the development of a simplified tool based on analytical formulations. [less ▲]

The batch-to-flow translation of inter- and intramolecular strategies for the diastereoselective preparation of the active pharmaceutical ingredient threo-methylphenidate hydrochloride is presented. Both inter- and intramolecular strategies imply the telescoping of multiple processing steps and the generation of unstable diazo species under continuous-flow conditions. The intermolecular strategy relies on an unprecedented continuous-flow Rh-catalyzed intermolecular C–H carbene insertion, providing enriched threo-N-Boc methylphenidate in 38% or 19% isolated yield according to sequential or fully telescoped processes, respectively. Quantitative Boc-deprotection is carried out off-line. The intramolecular strategy relies on a continuous-flow thermal intramolecular C–H carbene insertion, providing enriched threo-methylphenidate hydrochloride in 70% isolated yield. A continuous-flow photochemical alternative is also presented. The critical step of the most promising intramolecular strategy is implemented on the mesoscale in a pilot-scale continuous-flow reactor. [less ▲]

The genomic profile of multiple myeloma (MM) has prognostic value by dividing patients into a good prognosis hyperdiploid group and a bad prognosis non-hyperdiploid group with a higher incidence of IgH translocations. This classification, however, is inadequate and many other parameters like mutations, epigenetic modifications and genomic heterogeneity may influence the prognosis. We performed a genomic study by array-based comparative genomic hybridization (aCGH) on a cohort of 162 patients to evaluate the frequency of genomic gains and losses. We identified a high frequency of X chromosome alterations leading to partial Xq duplication, often associated with Xi deletion in female patients. This partial X duplication could be a cytogenetic marker of aneuploidy as it is correlated with a high number of chromosomal breakages. Patient with high level of chromosomal breakage had reduced survival regardless the region implicated. A higher transcriptional level was shown for genes with potential implication in cancer and located in this altered region. Among these genes, IKBKG and IRAK1 are members of the NFKB pathway which plays an important role in MM and is a target for specific treatments. [less ▲]

Two studies investigate whether employees viewing discretionary safety activities as part of their job role (termed safety citizenship role definitions, SCRDs) plays an important part in predicting two types of safety violation: routine violations conceptualized as related to an individual’s available cognitive energy or ‘effort’; and situational violations, which are those provoked by the organization (Reason, 1990). Study 1 showed SCRDs predicted situational violations only, and partially mediated the relationships between Perceived Management Commitment to Safety (PMCS) and work engagement with situational violations. These findings add to those by Hansez and Chmiel (2010), showing that routine and situational violations have predictors that differ. Study 1 findings also extend research reported by Turner et al. (2005), by showing that the effect of Job Control on SCRDs was mediated by both PMCS and work engagement. In study 2, participation in discretionary safety activities (safety participation) mediated the relationship between SCRDs and situational violations. Similar to study 1 The link between SCRDs and routine violations was non-significant and, strikingly, so was the link between safety participation and routine violations. These results support the view that processes involving SCRDs and safety participation are not cognitive-energetical in nature. In addition, study 2 findings extend previous work by Neal and Griffin (2006) by showing that SCRDs and safety knowledge partially mediated relationships between safety motivation and safety participation, whereas the direct effect of safety motivation on safety participation was non-significant. The results from both studies support the view that SCRDs are important in predicting situational violations. In study 2 SCRDs were shown to partially mediate the relationship between safety motivation and selfreported participation in discretionary safety activities (Safety Participation) which, in turn, related to situational violations. Interestingly there was no significant direct link between SCRDs and situational violations. These findings support the view that the effect of SCRDs on situational violations is fully mediated by participation in discretionary safety activities. [less ▲]
