The mechanism behind the immunostimulatory effect of the cationic liposomal vaccine adjuvant dimethyldioctadecylammonium and trehalose 6,6′- dibehenate (DDA:TDB) has been linked to the ability of these cationic vesicles to promote a depot after administration, with the liposomal adjuvant and the antigen both being retained at the injection site. This can be attributed to their cationic nature, since reduction in vesicle size does not influence their distribution profile yet neutral or anionic liposomes have more rapid clearance rates. Therefore the aim of this study was to investigate the impact of a combination of reduced vesicle size and surface pegylation on the biodistribution and adjuvanticity of the formulations, in a bid to further manipulate the pharmacokinetic profiles of these adjuvants. From the biodistribution studies, it was found that with small unilamellar vesicles (SUVs), 10% PEGylation of the formulation could influence liposome retention at the injection site after 4 days, whilst higher levels (25 mol%) of PEG blocked the formation of a depot and promote clearance to the draining lymph nodes. Interestingly, whilst the use of 10% PEG in the small unilamellar vesicles did not block the formation of a depot at the site of injection, it did result in earlier antibody response rates and switch the type of T cell responses from a Th1 to a Th2 bias suggesting that the presence of PEG in the formulation not only control the biodistribution of the vaccine, but also results in different types of interactions with innate immune cells. © 2012 Elsevier B.V.

In this paper, we first overview the French project on heritage called PATRIMA, launched in 2011 as one of the Projets d'investissement pour l'avenir, a French funding program meant to last for the next ten years. The overall purpose of the PATRIMA project is to promote and fund research on various aspects of heritage presentation and preservation. Such research being interdisciplinary, research groups in history, physics, chemistry, biology and computer science are involved in this project. The PATRIMA consortium involves research groups from universities and from the main museums or cultural heritage institutions in Paris and surroundings. More specifically, the main members of the consortium are the two universities of Cergy-Pontoise and Versailles Saint-Quentin and the following famous museums or cultural institutions: Musée du Louvre, Château de Versailles, Bibliothèque nationale de France, Musée du Quai Branly, Musée Rodin. In the second part of the paper, we focus on two projects funded by PATRIMA named EDOP and Parcours and dealing with data integration. The goal of the EDOP project is to provide users with a data space for the integration of heterogeneous information about heritage; Linked Open Data are considered for an effective access to the corresponding data sources. On the other hand, the Parcours project aims at building an ontology on the terminology about the techniques dealing with restoration and/or conservation. Such an ontology is meant to provide a common terminology to researchers using different databases and different vocabularies.

This thesis presents and discusses the results of ambient seismic noise correlation for two different environments: intraplate and Mid-Atlantic Ridge. The coda wave interferometry method has also been tested for the intraplate data. Ambient noise correlation is a method that allows to retrieve the structural response between two receivers from ambient noise records, as if one of the station was a virtual source. It has been largely used in seismology to image the subsurface and to monitor structural changes associated mostly with volcanic eruptions and large earthquakes. In the intraplate study, we were able to detect localized structural changes related to a small earthquake swarm, which main event is mR 3.7, North-East of Brazil. We also showed that the 1-bit normalization and spectral whitening result on the loss of waveform details and that the phase auto-correlation, which is amplitude unbiased, seems to be more sensitive and robust for our analysis of a small earthquake swarm. The analysis of 6 months of data using cross-correlations detect clear medium changes soon after the main event while the auto-correlations detect changes essentially after 1 month. It could be explained by fluid pressure redistribution which can be initiated by hydromechanical changes and opened path ways to shallower depth levels due to later occurring earthquakes. In the Mid-Atlantic Ridge study, we investigate structural changes associated with a mb 4.9 earthquake in the region of the Saint Paul transform fault. The data have been recorded by a single broadband seismic station located at less than 200 km from the Mid-Atlantic ridge. The results of the phase auto-correlation for a 5-month period, show a strong co-seismic medium change followed by a relatively fast post-seismic recovery. This medium change is likely related to the damages caused by the earthquake’s ground shaking. The healing process (filling of the new cracks) that lasted 60 days can be decomposed in two phases, a fast recovery (70% in ~30 days) in the early post-seismic stage and a relatively slow recovery later (30% in ~30 days). In the coda wave interferometry study, we monitor temporal changes of the subsurface caused by the small intraplate earthquake swarm mentioned previously. The method was first validated with synthetics data. We were able to detect a change of 2.5% in the source position and a 15% decrease of the scatterers’ amount. Then, from the real data, we observed a rapid decorrelation of the seismic coda after the mR 3.7 seismic event. This indicates a rapid change of the subsurface in the fault’s region induced by the earthquake.

The purpose of this paper is to bring into focus philosophical and logical concerns relating to specific rules that govern the role of the libero in volleyball. The authors contest that the introduction of the position of the libero in volleyball may have actually undermined the continuing logic of the rules of the game. In addressing these questions the authors offer theoretically based rule-change proposals for the sport of volleyball that could be used to inform future training methods or development programmes at both the participatory and elite levels. Discussion may also inform the development of new tools of analysis (e.g. computer software) or the creation of a new breadth of match simulation resources to enhance athlete performance. These tools and devices could then be presented to volleyball coaches in an effort to resolve the issues that have come to light and further inform the philosophical and logical debates about the role of the libero in volleyball.

The purpose of this thesis was to examine the choice patterns that lead to conversion from Catholicism to Protestantism and the role of Vodou after conversion. This study highlights disappointment with the church as the leading cause of conversion in Haiti. Other causes significant to the study were examined. In illness and healing lie the controversies of religious conversion in Haiti. The only way to cure Satanic Illness is by resorting to magic. However, conversion to Protestantism means rejection of Vodou and all of its practice. A secondary purpose is to determine the role of Vodou after conversion. A total of 100 participants between the ages of 18 to 44 were included in this study. Seven percent (7%) converted for economic reasons, 43% selected disappointment with the church, 17% community/environment encounter, 13% sickness/near death experience, 2% economic and disappointment, 7% community/environment encounter and disappointment with the church, 9% disappointment sickness and near death experience, 1% economic and sickness near death experience, 1% economic and community/environment encounter. Findings suggest that Vodou is deeply rooted in Haitian identity, though all Haitians may not practice Vodou; but there are characteristics in the Haitian society that suggest that Haitians are Vodouisant. For the conversion process to be successful in Haiti it has to deeply acknowledged Vodou, the religion practiced by the masses in Haiti.

This chapter situates Camus' Hellenism in the context of other French modernists in literature. It examines Camus' youthful Hellenism, rooted in his own experiences growing up in French Algeria. It then examines the philosophical dimensions of his defence of classical mesure, in the context of the 20th century European disaster. It also looks at his reading of Greek tragedy, and his key contrast of Prometheus as rebel, with Satan.
