Agricultural accumulation has been one of the main source determined the social differentiation in Vietnamese countryside. The complexities of agrarian changes under the post - socialist industrialization with high rate of agricultural land conversion in recent context reveal the new forms of capital accumulation and social differentiation. This research investigates how land conversion process to industrial zones and clusters affected to the way that different groups of peasant households accumulate their resources. The study was carried out in 3 districts of Hung Yen province from 2006 to 2010. The study results are as follows: first, the land conversion to industrialization has impact on not only the decline of household landholdings but also the changes value of land which are the sources of social conflicts and informal land transfer. Second, in the context of land conversion to industrialization with tiny plots of land, low return from agricultural production and more opportunities of non-farm activities, even when non-farm employment is very profitable, peasant households are not likely to give up their land but maintaining agricultural production for not only their basic and secure livelihood but also for their identity. Third, among the affected peasant groups, the households with non-farm background tend to be in better position in engaging to high - earning activities. They are likely the rich peasants in opposed to the poor group with farming background and lost more than 50% of their agricultural land. This research has showed that the industrialization policies have to deal with the proportion of agricultural land would be transferred for industrialization zones and other measures in order to limit the conflicts as well as the social differentiation in countryside.

A major aim of the Pragmatic Web is “to support communities to put ontologies in context”. As a contribution to this aim, we present the framework we developed to analyze the way we attempted to contextualize the ontologies underlying a set of semantic knowledge services dedicated to communities of practice. The framework was derived from the “Ontology Framework” elaborated by members of the Ontology Engineering community during the Ontology Summit 2007. Both frameworks define a series of “pragmatic dimensions” of ontologies. Because our derived framework does not cover all possible dimensions, we propose to complement it, by relying on existing work from the Ontology Engineering community in general, and from the Pragmatic Web community in particular. In conclusion, we invite the Pragmatic Web community to pursue such a work by jointly elaborating a consensual “Pragmatic Ontology Framework”. [less ▲]

Le rôle joué par les femmes de pouvoir au Moyen Âge et au tout début de la Renaissance dans la commande d’œuvres artistiques et culturelles constitue un champ de recherche de plus en plus prolifique. La présente collection d’articles, suscitée par une journée d’études intitulée "Le mécénat féminin en France et en Bourgogne (XVe-XVIe siècles). Nouvelles perspectives", qui a eu lieu à l’Université de Liège en 2010, illustre l’importance des femmes mécènes, en France et en Bourgogne, dans les domaines de l’architecture, de l’orfèvrerie, des manuscrits enluminés, de la peinture et de la sculpture, ainsi que dans la traduction et dans l’organisation des cérémonials. Dans leurs fonctions respectives, celles de reine, reine mère, duchesse, régente, dame d’honneur, les femmes font usage des œuvres d’art et des rites pour promouvoir leurs intérêts personnels et dynastiques, confrontées qu’elles sont aux difficultés liées à leur sexe et à leur statut de femme de pouvoir, ou à des difficultés telles que les rivalités, la guerre, ou la folie. Même s’il est clair que les cours française et bourguignonne constituent l’espace le plus favorable à l’efflorescence du mécénat féminin, cette collection démontre toutefois l’existence d’un même phénomène, important, en dehors des sphères royales.

The impact of pollution on the environment is causing several problems that are to be reduced as much as possible. One important example is the production of CO2 that is emitted by many transport and industrial applications. An interesting solution is to view CO2 as a source instead of a product that can be stocked. The case considered in this work is the CO2 reformation of methane producing hydrogen and CO. It is an endothermic reaction, for which the activition barrier needs to be overcome. The method of Dielectric Barrier Discharge can do this efficiently. The process relies on the collision of electrons, which are accelerated under an electrical field that is created in the discharge area. This leads to the formation of reactive species, which facilitate the abovementioned reaction. The determination of the electron density is performed by PLASIMO. The study is subsequently continued using the Reaction Engineering module in COMSOL (with an incorporated kinetic mechanism) in order to model the discharge phase. Then COMSOL (continuity and Navier-Stokes equations) is used to model the flow in the post-discharge phase. The results showed that both a 2D and 3D model can be used to model the chemical-plasma process. These methods need strongly reduced kinetic mechanism, which in some cases can cause loss of precision. It is also observed that the present experimental set-up that is modeled needs to be improved. A suggestion is made. [less ▲]

The goal of RIC allo-SCT is to harness the graft-versus-leukemia (GVL) effect, while minimizing toxicities and the risk of GVHD. However, prior studies have shown a lower risk of relapse in AML patients (pts) who experienced chronic GVHD after RIC allo-SCT versus in those who did not. Here, we investigated the impact of occurrence of GVHD on transplantation outcomes in a large cohort of AML pts given allogeneic PBSC after RIC conditioning. Data from 1859 AML pts in first (n=1439) or second (n=420) CR transplanted between 2000 and 2009 following a RIC regimen at EBMT affiliated centres were analyzed. Pts were given PBSC from HLA-identical sibling (MRD, n=1208), or from HLA-matched unrelated donors (MUD, n=651). Median pt age at transplantation was 56 y (range, 18–77). 338 male pts were given grafts from female donors. RIC was based on low-dose TBI in 520 (28%) pts, while the remaining pts received chemotherapy-based RIC. ATG was given in 269 (22%) MRD and in 267 (41%) MUD recipients, respectively, while 151 (13%) MRD and 165 (25%) MUD recipients received in-vivo T cell depletion with alemtuzumab. The impact of chronic GVHD on relapse risk, non-relapse mortality (NRM), leukemia-free survival (LFS), and overall survival (OS) was assessed using time-dependent multivariate Cox models and in a landmark analysis at 18 months after transplant. Three-year incidences of relapse, NRM, LFS and OS were 34±1%, 15±1%, 51±2% and 60±2% in MRD recipients, respectively, and 34±2% (p=NS), 24±2% (P<0.001), 42±2% (P=0.001) and 47±2% (P=0.001) in MUD recipients, respectively. Grade II, III and IV acute GVHD were observed in 133 (11%), 61 (5%) and 30 (2%) MRD recipients and in 119 (18%), 41 (6%) and 24 (4%) MUD recipients, respectively. The 3-y cumulative incidence of chronic GVHD was 47%. Fifty-three percent of patients with chronic GVHD had extensive chronic GVHD, while the remaining 47% had limited chronic GVHD. In multivariate analyses, occurrence of grade II-IV acute GVHD was associated with a lower risk of relapse (HR=0.8; P=0.04), a higher risk of chronic (HR=2.2; P<0.001) and extensive chronic GVHD (HR=2.8; P<0.001), a higher risk of NRM (HR=2.4 P<0.001), a worsened LFS (HR=1.3; P=0.01), and a worsened OS (HR=1.5; P<0.001). In multivariate time-dependent analyses, occurrence of limited chronic GVHD was associated with a lower risk of relapse (HR=0.7; P=0.05), comparable NRM (HR=1.4; P=0.16), comparable LFS (HR=0.9; P=0.29) and better OS (HR=0.5; P<0.001), while occurrence of extensive chronic GVHD was associated with a lower risk of relapse (HR=0.6; P=0.01), higher NRM (HR=3.2; P<0.001), a trend for worsened LFS (HR=1.3; P=0.06) and comparable OS (HR=0.9; P=0.34). The median interval from transplantation to occurrence of chronic GVHD was 163 (range, 100–1545) days. To further assess the graft-versus-leukemia effect of chronic GVHD, we performed a landmark analysis in patients who were leukemia-free at 18 months after transplantation (n=776). Median follow-up from this landmark time-point was 24 (range, 0.1–112) months. Two-year relapse, NRM, LFS and OS were 16±2%, 2.5±1%, 82±2%, and 89±2%, respectively, in patients without chronic GVHD before the landmark time-point, versus 9±1% (P=0.001), 8±1% (P<0.001), 83±2% (P=0.65), and 86±2% (P=0.38), respectively, in patients with chronic GVHD before the landmark time-point.In conclusion, in this cohort of AML patients transplanted in remission, occurrence of chronic GVHD was associated with a lower risk of relapse that translated to better OS in patients with limited chronic GVHD but not in those with extensive chronic GVHD who experienced higher long term NRM, highlighting the need for long term prospective assessment of long term effects and quality of life in patients receiving RIC allo-SCT.

Vietnam locates in the Asia-the most active region, where gains the highest economic growth rate and highest milk consumption in the world. Vietnam also ranks the second among the highest milk productivity in the Asia and milk consumption is increasing rapidly. However, the dairy industry in Vietnam is currently able to meet only 22% of domestic demand; the remaining amount has been imported (VOV/VNA, 2008). In addition, raw milk price is very low while retail price is too high. It leads to low effective in the production of the whole chain. This paper is based on the value chain approach within both quantitative and qualitative methods to evaluate a typical fresh value chain in the North of Vietnam in (Moc Chau platation) in 2008 - 2010. The findings show that the dairy plant is the most powerful actor in the chain and it drives the whole chain while power of dairymen is very weak. The value added of the chain is distributed unequally among its actors in whom more benefitable for non-dairy cow producers. In particular, the value added in dairy cow stage would be much lower.

En Afrique Subsaharienne, les taux d’adhésion aux mutuelles de santé restent généralement à des niveaux très faibles. Cet article vise à synthétiser les résultats des enquêtes déjà réalisées pour identifier les facteurs qui influencent la décision d’adhérer ou non à ces mutuelles. Au-delà des différences méthodologiques entre ces travaux, notre synthèse fait ressortir deux facteurs majeurs qui étaient plutôt attendus (la capacité financière des populations et la qualité des soins) et les resitue dans une perspective plus large. Elle permet également d’identifier quelques autres paramètres qui semblent aussi jouer un rôle significatif même si les convergences entre les enquêtes sont moins nettes. [less ▲]

Summary: The aim of this present research was to study the antifungal properties of lactic acid bacteria (LAB) isolated from fermented Mill flour and fermented cassava in order to use them for biopreservation. Antifungal activity of these LAB were assessed in MRS solid medium against food spoilage moulds as Aspergillus niger MUCL 28699, Aspergillus niger CWBIF194, Aspergillus tubingensis MP1 and Penicillium crustosum MY1. Three strains, Lactobacillus plantarum VE56, Weissella cibaria FMF4B16 and Weissella paramesenteroides LC11 were selected among 116 for their strongest inhibitory activity and their broad inhibitory spectrum against food moulds. The 4-fold concentrated supernatant of L. plantarum VE56 and W. paramesenteroides LC11 had the strongest inhibitory activity to compare to W. cibaria FMF4B16. The antifungal activity of the cell-free supernatant was pH dependent and insensitive to proteolytic enzymes action suggesting that the inhibitory activity was due to other compounds than proteins. The identification of antifungal compounds by chromatographic studies highlighted the production of phenyllactic acid by the three strains. In addition, 2-hydroxy-3-methylpentanoic acid and 2-hydroxy-4-methylpentanoic acid were produced by L. plantarum VE56 and W. paramesenteroides LC11. However, the concentration assessed in the supernatant was lower than the minimal inhibitory concentration showing a synergic action of all these produced compounds. The effect of the antifungal supernatant of L. plantarum VE56 and W. paramesenteroides LC11 on Aspergillus flavus NRRL 3357 resulted to an inhibition of conidial development and aflatoxin B1 production which was reflected in decreased gene expression of brlA (conidiophore specific transcription factor) and laeA (global regulator of secondary metabolism). These two bacteria also delayed Penicillium expansum MUCL 14498 conidial development in bread. [less ▲]

BACKGROUND AND PURPOSE: The clinical picture of hand atrophy related to a cervical rib or elongated C7 transverse process was well described in the modern literature by Gilliatt and Sumner; in 1970, they reported a series of nine patients whose motor status was stabilized following brachial plexus decompression. We report here seven patients suffering from thoracic outlet syndrome (TOS), who developed hand atrophy, sometimes because of diagnostic delay. METHODS: The patient's charts were analysed retrospectively. RESULTS: The seven patients were all female; the mean age was 43 years. The first complaints were arm pain and paresthesias lasting six months to 5 years. Three patients were treated with C56/C67 discectomy plus disc prosthesis (one patient), ulnar neurolysis at the elbow (the same patient), carpal tunnel release (one patient), and intravenous immunoglobulins (one patient) before TOS diagnosis. Hand atrophy, severe in five patients, was present at presentation. All patients underwent brachial plexus decompression by the anterior (four), posterior (two), or transaxillary (one) approach. This last approach was completed 18 months later by brachial plexus neurolysis via the anterior approach. Postoperatively, motor deficit was improved in two patients and stabilized in five patients. CONCLUSIONS: Physicians' unfamiliarity with TOS diagnosis or their reluctance to accept the diagnosis without electrical confirmation can lead to hand atrophy. Brachial plexus decompression at this stage usually stabilizes the deficit. [less ▲]
