Simulation of Pessimism Influence on Choice of Farming Strategy under Uncertainty
Weather-related risks can substantially affect the crop volume depending on time and intensity of agricultural operations performed by the farmer. However, decisions under uncertainty are in some way also liable to another risk - that of excessively optimistic or pessimistic estimation of the decision maker. The paper presents results of optimistic and pessimistic farmer's agricultural operations efficiency based on the analysis of the developed discrete-event stochastic simulation model. The aim of the model is to obtain quantitative estimation of optimistic and pessimistic farmer's choice of agricultural operation strategy efficiency under fluctuation of weather conditions.

Modeling Wind Turbines in the Simulation of Power System DynamicsThis paper deals with the modeling of variable speed wind turbines for stability studies. Using the space-phasor representation and the fundamental relationships governing the operation of the machine quasi stationary model, suitable control algorithms for the simulation of the doubly-fed induction machine (DFIM) as well as the permanent magnet synchronous machine (PMSM) operating on an interconnected system are developed. The control schemes include the pitch-angle/speed control and the decoupled control of the real and reactive power outputs. As an additional modeling option, the generic model for variable speed machine has been introduced. The models were then implemented on a representative test network, and simulations have been carried out to observe the response of the control system to typical abnormal situations such as three phase grid faults to compare the accuracy of the generic models with the detailed quasi-stationary (QSS) models.

Mathematical Modelling of Induction Motor Transient Processes During Stator Winding InterruptionThis research presents induction motor mathematical model in coordinate axis's α, β, which allows to learn transient processes in rotor and stator circuits in the conditions of stator windings opening. Such kind of researches is nowadays actual due to impossibility of main calculated values measuring directly, but only on the stator terminals. Induction motor mathematical model forms Park-Gorev equations in α, β coordinate axis. It is preferable to use this coordinate system because it allows comparing the results of mathematical modeling in one of the phases with experimental data without transformations.

Une relecture sociologique des parcours des étudiants français : entre segmentation et professionnalisation
Authors: Erlich Valérie , Verley Élise 
Published: January 2011

Résumé En France, l’exploitation transversale de données empiriques de sources diverses révèle sur dix ans une hiérarchisation et une professionnalisation des formations et des orientations et la sélectivité scolaire exercée sur les orientations et les parcours des étudiants. Sous l’effet de la crise économique et des réformes, la recomposition des hiérarchies a accru la sélectivité des formations professionnalisantes accueillant des publics plus sélectionnés scolairement et socialement. Deux objectifs sont poursuivis : adapter l’université à la massification et à l’hétérogénéité des publics ; répondre à l’attente des milieux économiques en préparant les étudiants à leur insertion professionnelle. Que les politiques volontaristes poussent les bacheliers professionnels et technologiques vers les filières courtes ou qu’elles orientent les bacheliers généraux vers des filières professionnalisantes et sélectives en université, professionnalisation et sélection caractérisent les nouveaux parcours étudiants. Si la vocation professionnelle des formations s’impose comme la norme, l’université et l’enseignement supérieur ne doivent pas oublier leur fonction sociale et culturelle.
El paisaje en la literatura francesa a partir del siglo XIX y sus relaciones con la pintura
Authors: Leguen Brigitte 
Published: January 2011

Este artículo aborda los valores del paisaje tal y como aparece en la literatura francesa a partir del siglo XIX y sus conexiones con la pintura del mismo período. El paisaje campestre que nos hace descubrir los ingleses y los alemanes y el paisaje urbano que cambia radicalmente a partir de la revolución industrial, ofrecen una dimensión simbólica y social que se proyecta en el campo literario y artístico. La sociedad francesa del siglo XIX experimenta importantes cambios socio-políticos que repercuten obviamente en toda la literatura desde el Romanticismo hasta los grandes replanteamientos de la post-modernidad.
El siglo XIX es en Francia el gran siglo de la literatura; los escritores más relevantes, Chateaubriand, Stendhal, Hugo, Balzac se detienen en la contemplación del paisaje y establecen nuevas relaciones y correspondencias con la naturaleza. La recuperación de los espacios y su polisemia concierne también todo el siglo XX y el período actual. Poetas, escritores y pintores siguen integrando el paisaje en su creación. Ya lo decía Fernand Braudel, los paisajes y los espacios no son únicamente realidades del presente pero también y sobre todo supervivencias del pasado; «la terre est, comme notre peau, condamnée à conserver la trace des blessures anciennes».

HIV Replication in CD4+ T Lymphocytes in the Presence and Absence of Follicular Dendritic Cells: Inhibition of Replication Mediated by α-1-Antitrypsin through Altered IκBα Ubiquitination
Authors: Zhou Xueyuan , Shapiro Leland , Fellingham Gilbert , Willardson Barry M. , Burton Gregory F. 
Published: January 2011

Abstract
Follicular dendritic cells (FDCs) increase HIV replication and virus production in lymphocytes by increasing the activation of NF-κB in infected cells. Because α-1-antitrypsin (AAT) decreases HIV replication in PBMCs and monocytic cells and decreases NF-κB activity, we postulated that AAT might also block FDC-mediated HIV replication. Primary CD4+ T cells were infected with HIV and cultured with FDCs or their supernatant with or without AAT, and ensuing viral RNA and p24 production were monitored. NF-κB activation in the infected cells was also assessed. Virus production was increased in the presence of FDC supernatant, but the addition of AAT at concentrations &gt;0.5 mg/ml inhibited virus replication. AAT blocked the nuclear translocation of NF-κB p50/p65 despite an unexpected elevation in associated phosphorylated and ubiquitinated IκBα (Ub-IκBα). In the presence of AAT, degradation of cytoplasmic IκBα was dramatically inhibited compared with control cultures. AAT did not inhibit the proteasome; however, it altered the pattern of ubiquitination of IκBα. AAT decreased IκBα polyubiquitination linked through ubiquitin lysine residue 48 and increased ubiquitination linked through lysine residue 63. Moreover, lysine reside 63-linked Ub-IκBα degradation was substantially slower than lysine residue 48-linked Ub-IκBα in the presence of AAT, correlating altered ubiquitination with a prolonged IκBα t1/2. Because AAT is naturally occurring and available clinically, examination of its use as an inhibitory agent in HIV-infected subjects may be informative and lead to the development of similar agents that inhibit HIV replication using a novel mechanism.
Current and Potential Distribution Modeling for Cathodic Protection of Tank Bottoms
Authors: Bazzoni B. , Lorenzi S. , Marcassoli P. , Pastore T. 
Published: January 2011

Abstract
Aboveground tanks for the storage of liquid hydrocarbon are often erected with a secondary containment membrane installed below the tank bottom to prevent soil contamination in case of leakage. The design of impressed current cathodic protection in the presence of the plastic membrane is based on distributed anodes installed in the space between the tank bottom and the membrane; among available anodes, the most commonly used are the titanium grid or ribbon activated with noble metal oxides. The configuration of the grid or ribbon anode system confined in the closed space between the bottom and membrane creates specific issues concerning the electrochemical reactions occurring at the anode and cathode, the ohmic drops in the anode system, and the potential and current distribution at the cathode. Results of a number of numeric simulations performed to predict the actual distribution of current and potential are given. Design criteria are discussed.

The genetics behind osteoarthritis: Asian focus
Authors: Tammachote Rachaneekorn 
Published: January 2011

Abstract
Osteoarthritis (OA), a degenerative joint disease, is the most common form of arthritis in the elderly. Problems arising from the condition are not only health, physical, and psychological, but also economical and social. OA is a complex disease causes by environmental factors (obesity, female gender, advancing age) and genetics. A strong genetic contribution to primary OA has been observed in several studies. Asian population is undoubtedly genetically different from European, whom most studies have been performed. This review systematically compares results of molecules involved with OA from studies performed on Asian and Caucasian populations. The clear differences between Asian and Caucasian populations may be from the sex- and ethnic-specific nature of the disease, as well as from the inclusion criteria of the studies. Global collaboration is highly significant in understanding genetic underlying OA. Knowledge gained from genetic study is important to the development of prevention and therapeutic intervention, and to identify individuals at risk of developing severe or progressive OA.
