The anionic polymerization of 4-vinylpyridine (4VP) has been investigated in 9/1 pyridine/THF at 0 °C. After characterization of the living character of 4VP polymerization, its copolymerization with tert-butyl methacrylate (tBMA) has been carried out also successfully. Their relative reactivity ratios have been determined. Solvent composition as well as temperature have been varied in order to evaluate their influence on the final molecular characteristics of the polymers. Finally, a new SEC methodology in 8/1/1 N,N-dimethylformamide/triethylamine/pyridine has been developed. [less ▲]

As an illustration of the frantic development of (meth)acrylic esters anionic polymerization during the last decade, three significant breakthroughs will be presented and analyzed: - extension of the LAP (ligated anionic polymerization) concept to the practical synthesis of both high iso- or syndio high MW PMMA; - the production of "perfect" hydrocarbon gels from tailored PMMA-polybutadiene-PMMA triblock copolymers; - the use of reactivity "boosters" allowing to climb back up the nucleophilic reactivity scale, i.e. initiating styrene, dienes and (meth)acrylates polymerization with alcoholates and silanolates.

Circular migration has been portrayed as the ultimate solution for migration governance. In fact, policy makers and academics consider circular migration and other temporary forms of migration as a way to obtain mutual gains for sending countries, receiving countries and migrants (Vertovec, 2007). Circular migration encompasses different type of processes such as temporary migration programs, return migration, limited term contracts and temporary visas (Yamashiro: 2013, Oda 2010a). In order to understand the advantages and disadvantages of circular migration, it is necessary to unpack each of these programs. The assumption that temporary migration is beneficial for emigration countries, immigration countries and migrants needs to be analysed more critically, since these programs have a transformative effect both in sending and receiving societies. For instance, in some cases temporary migration can disrupt the basis and components of citizenship, identity or ethnicity. One of the most representative cases to illustrate the disruptive effect of temporary programs in the social and political order is the case of Japanese-Brazilian migrants retuning to Japan (Hokara, 2002). Since 1990, the Japanese government approved a law that enables foreign nationals of Japanese ancestry to enter Japan as temporary workers. Several scholars have described this phenomenon as a “temporary status program”, “long term resident program” (Oda, 2010), “return migration program” (Touro, 2001) and “limited-term contracts” (Terasawa, 2000). One of the main contributions in the study of these Brazilian Nikkeijin (descendants of Japanese emigrants) is their conceptualization as secondary citizens (Yamanaka, 2003). According to Joppke (2007), citizenship has three different aspects: status, rights and identity. Using this framework, this essay argues that the Control and Refugee Recognition Act enabling Brazilian immigrants to return temporally to Japan has created a new status of quasi-citizenship. Analysing the circular migration of this population from this perspective enable us to understand the role of the Japanese government on shaping restrictive immigration laws and the living condition of the Nikkeijin. On the one hand, the first part of the essay argues that Nikkeijin migration is an instrument of social closure. The first part uses Joppke’s (2007) framework to demonstrate that Japanese-Brazilians are quasi-citizens in Japan with a legal status, economic rights and a common identity. On the other hand, the second part argues that there are three main obstacles that prevent this migrant community to be fully admitted as citizens. These three factors are the following: the state modelling and concerns role, the lack of accommodation of diversity in the Japanese society and finally the formation of a transnational community.

Poly(delta-valerolactone) [poly(deltaVL)] of high molecular weight (similar to40 000) and low polydispersity index (similar to1.05) was prepared by activated monomer cationic ring-opening polymerization of delta-VL initiated by the alcohol/HCl.Et2O system. A series of functional alcohols, e.g., 9-anthracenemethanol, 2-hydroxyethyl acrylate, 3-buten-1-ol, 2-bromoethanol, and 5-norbornene-2-metbanol, were successfully used to prepare asymmetric telechelic poly(deltaVL), i.e., chains end-capped by the functional group of the alcohol in a-position and by an w-hydroxyl group. Ring-opening polymerization of delta-VL in the presence of alpha-methoxy-w-hydroxylpoly(ethylene oxide) and poly(ethylene glycol) led to amphiphilic di- and triblock copolymers, respectively. The polydispersity index of all these (co)polymers was low (similar to1.10). [less ▲]

Well defined graft copolymers have been synthesized by a nitroxide-mediated "living" free radical process using pre-formed macromonomers. Analysis of the graft systems revealed that the macromonomer was efficiently incorporated into the polymeric back-bone to give block copolymers of controlled molecular weight and narrow polydispersi-ties. An added benefit of the "living" free radical process is that macromonomers, such as polylactide or polycaprolactone, which contain reactive functional groups can be used to form novel graft Systems using this approach. Functionalized monomers or polymeric initiators were also used in the copolymerization mixture to give graft Systems with a variety of functional groups attached to the backbone. [less ▲]

This paper reviews our work on the fabrication of photobiochemical hybrid materials via immobilisation of photosynthetically active entities within silica materials, summarising the viability and productivity of these active entities post encapsulation and evaluating their efficiency as the principal component of a photobioreactor. Immobilisation of thylakoids extracted from spinach leaves as well as whole cells such as A. thaliana, Synechococcus and C. caldarium was carried out in situ using sol-gel methods. In particular, a comprehensive overview is given of the efforts to find the most biocompatible inorganic precursors that can extend the lifetime of the organisms upon encapsulation. The effect of matrix-cell interactions on cell lifetime and the photosynthetic efficiency of the resultant materials are discussed. Precursors based on alkoxides, commonly used in "Chimie Douce" to form porous silica gel, release by-products which are often cytotoxic. However by controlling the formation of gels from aqueous silica precursors and silica nanoparticles acting as "cements" one can significantly enhance the life span of the entrapped organelles and cells. Adapted characteristic techniques have shown survival times of up to 5 months with the photosynthetic production of oxygen recorded as much as 17 weeks post immobilisation. These results constitute a significant advance towards the final goal, long-lasting semi-artificial photobioreactors that can advantageously exploit solar radiation to convert polluting carbon dioxide into useful biofuels, sugars or medical metabolites. © 2010 The Royal Society of Chemistry.

Living related liver transplantation (LRLT) in adult recipients has been recently developed to overcome the organ donor shortage, but LRLT leaves the healthy donors at risk of serious post-operative complications, or even death. The aim of this paper is to report the prospective evaluation of the initial experience of adult LRLT at the University of Liege. From March 2002 till March 2003, in a consecutive series of 35 adult liver transplantations, five recipients (mean age : 51 years) underwent LRLT, including one retransplantation. Indications for transplantation were autoimmune hepatitis, hepatitis B virus related cirrhosis with hepatocarcinoma (two cases), hepatitis C virus related cirrhosis with hepatocarcinoma, and ischemic intrahepatic bile duct necrosis 10 years after primary liver transplantation. Mean age of the donors was 34 years (range : 21-53 years). All donation cases were intra familial at first degree. The right lobe was used as a graft in four cases and the left lobe in one case. All right lobe donors developed transient hyperbilirubinemia and hypocoagulation for 4 to 6 days. No severe complication (transfusion, bile duct fistula, reintervention, rehospitalization) nor significant long-term sequelae were observed in the donors. In the recipients, graft function was immediate, and there was no small-for-size syndrome. One recipient developed biliary fistula treated by reoperation. One recipient died from invasive aspergillosis 11 days after the procedure. The four other recipients were alive without recurrence of the disease at follow-up. This report confirmed that LRLT may be a valuable alternative to cadaveric liver transplantation in the era of organ donor shortage. However, even if there was no severe complication for the donors in our preliminary experience, LRLT puts healthy living donors at risk of significant morbidity and even death. [less ▲]

Homopolymerization of the unsaturated cyclic ester, 6,7-dihydro-2(5H)-oxepinone (DHO), and copolymerization with epsilon-caprolactone (epsilon-CL) are an easy way to produce unsaturated aliphatic polyesters in a controlled manner, Polymerization of DHO initiated by Al((OPr)-Pr-i)(3) in toluene at room temperature proceeds by a coordination-insertion mechanism and is living as certified by the agreement between the experimental molecular weight at total monomer conversion and the value predicted from the initial monomer to initiator molar ratio. The polydispersity is also low (Mw/Mn less than or equal to 1.2). Random copolymerization of DHO and epsilon-CL leads to the same conclusion. Beyond the complete monomer conversion, the poly(DHO) chains experience mainly intermolecular transesterification reactions at the same rate as poly(epsilon CL) under the same conditions. The livingness of the ROP of both DHO and epsilon-CL allows diblock copolymers to be synthesized with predicted composition and molecular weight. Homopoly(DHO) is semicrystalline with Tm at 35°C and Tg at -50°C. Tm and thermal stability can be modulated by copolymerization of DHO with epsilon-CL. [less ▲]

The aim of the study is to finely describe and understand how two dogs’ presence on the one hand, and dog-centred activities on the other hand, can change the way in which resident psychotic patients are in touch with their (human and non human) environment. Our hypothesis is that the presence of the dogs alters the sensory and perceptive qualities of a situation, opening the way for different ranges of commitment and affectivity. More precisely, the dogs are considered as subjective agents that make people doing things and make the patients feeling specific emotions, depending on the position they have in the human-dog interaction. When the patients learn to cope with the dogs, or when they learn to train them, they get in touch with the dogs in an original way. With time, they become more skilled in the management of affect and communication. These skills become stabilised through the repetition of gestures or the acquisition of other body techniques (Mauss). In order to address these questions, we conducted an ethnographic study that lasted one year. The ethnography focused on the precise qualitative description of bodies, attention process, body postures and verbal and non-verbal communication that occur in the presence of the dog and during the dog-training sessions.
