This paper provides a new contribution to the simplified analytical treatment of collisions between two ships. It is directly connected to the well-known super-elements method, which is a simplified procedure allowing for a quick estimation of the damages caused to both the striking and struck vessels during such events. In this article, a new analytical formulation is presented for estimating the impact resistance provided by inclined ship side panels. Two different scenarios are treated. We first deal with the case of an impact between the oblique plate and the stem of the striking ship, and then we consider the situation where the inclined panel is impacted by the bulb. For these two scenarios, an analytical formulation relating the force and the penetration is provided and these developments are validated by comparing them to the results of finite elements simulations. Finally, the new inclined plate super-element is integrated in a simplified model of a frigate collided by another ship, and the resistance given by the superelements method is then compared to the one obtained by a numerical simulation of this collision.

Studies on nationalism were often interested with the city, especially the city centers. The politics of heritage, the architecture of public buildings and the design and use of central public spaces are often studied in relation to national identity politics. Municipal politics of the historical city in the face of central authorities’ urban politics is also frequently approached in the light of Nation-State building issues. If no doubt the consideration of city centers as a vantage point for understanding the relation between nationalism and the city is an interesting one that bore many fruits, we believe that a vantage point concentrating on the peripheries can highly contribute in unveiling other aspects of this relation. This paper aims at investigating the potentialities of this contribution. As the place where urbanization is taking place, the periphery is: - Where the national identity construction logic is put to test. First because, historically, it is here where the confrontation between the urban and the rural did first take place. Second, because rural exodus and migration, usually more important in the periphery, will continue to challenge it. - Where the city and the hinterland get connected through different national territory building networks. - Where the Nation-State central authorities will find the largest land reserves to develop their large emblematic projects. - Where urban fragmentation poses the strongest challenge to the unitarian message of nationalism, but also is where some nationalist movements might best develop In fact, the periphery represents equally a fertile ground for nationalism and for resistances to it. This paper will rely on the city of Beirut as a case study. [less ▲]

CC 77. Buenos Aires, Argentina. (2) Instituto de Biotecnología, CICVyA, INTA-Castelar. CC 77. Buenos Aires, Argentina. La adhesina F17 presenta variantes serológicas (F17a,F17b,F17c,F17d) que son expresadas por E.coli patógenos. Estos subtipos han sido detectados en bovinos con diarrea o septicemia y en ovinos septicémicos en países del hemisferio norte. F17 es altamente homóloga a fimbrias de P. mirabilis uropatógeno y H. influenzae biogr.aegyptius. En los bovinos, la expresión de F17 se ha asociado con varios factores de virulencia. En este trabajo se demuestra la presencia de fimbrias de la familia F17 en E.coli productoras de toxinas Shiga (Stx). Las cepas estudiadas provinieron de un brote de diarrea en un establecimiento de cría que afectó a 170 de un total de 600 terneros de 30-45 días. La detección de los subtipos de F17 se realizó por agluti-nación en lámina e immunodot y se confirmó por SDS-PAGE y Western blot. Las fimbrias F5 y F41 se investigaron por aglutinación en lámina. El antígeno de superficie CS31A se detectó por immunodot, confirmándose por SDS-PAGE y Western blot. Los genes que codifican para Stx (stx1, stx2) e intimina (eaeA) se detectaron por PCR, confirmándose la producción de Stx en células Vero. La producción de enterotoxina (StaP) se ensayó en ratón lactante. La serotipificación se realizó por la técnica de aglutinación. La detección de enterohemolisina (ehly) fue realizada en agar con 5% de eritrocitos lavados. Se comprobó la capacidad de colonización intestinal de las cepas F17+ por la técnica de adherencia in vitro a villi de ternero. En 7 de 9 animales estudiados se aislaron E.coli productores de F17 y/o stx+, eaeA+, ehly+. Dos cepas stx1+, eaeA+, ehly+ de los serotipos O153:H- y O159:H- expresaron fimbrias F17. Por su reactividad con sueros específicos y un peso molecular aparente de 20 kDa se las identificó como pertenecientes a los subtipos c y a, respectivamente. En el caso de la cepa del serotipo O159:H- se detectó también la presencia de una fimbria de 18.5 kDa con reactividad cruzada con antisuero F17 que podría corresponder a F17d o a una nueva variante dentro de la familia F17. El resto de los E.coli expresaron fimbrias F17 (c y a/18.5) ó bien fueron productores de Stx, correspondiendo a los patotipos O5:H-, stx1, eaeA+, ehly+; O26:H-(H11), stx2, eaeA+, ehly+; O26:H-(H11), stx1, eaeA+, ehly+; y O111:H-, stx1, eaeA+, ehly+. Todos los E.coli F17+ mostraron adherencia a villi de ternero. Ninguna de las cepas expresó los antígenos F5, F41, CS31A ni produjo toxina StaP. La adquisición de mecanismos de colonización no reportados previamente en cepas de E.coli productoras de toxinas Shiga plantea la posibilidad de la aparición de clones con un mayor perfil de virulencia en bovinos y/o humanos.

INTA Castelar. 2 Instituto de Genética. CNIA. INTA Castelar. La relación entre el genotipo y las formas de manifestación patogénica está demostrada para ciertos Retrovirus, y se ha descripto la presencia de determinantes de patogenia, tropismo tisular y virulencia en regiones del genoma proviral como LTR y env Sin embargo, esto no ha sido descripto para el Virus de la Leucosis Bovina (VLB), donde aún no se conocen las causas de desarrollo de las diferentes formas de la infección: el linfosarcoma (LS), la linfocitosis persistente (PL), o la forma aleucémica (AL). Con el objetivo de conocer si existe relación entre el genotipo proviral del VLB y las formas de evolución patogénica de animales infectados se secuenció la zona R-U5 de las regiones genéticas provirales LTR aisladas de 36 animales infectados naturalmente y con diferentes formas de evolución: 14 con linfosarcoma (LS), 11 con Linfocitosis Persistente (PL) y 10 portadores asintomáticos o aleucémicos (AL). La secuencia de nucleótidos reveló la presencia de 4 cambios fijos y característicos de los LTR de provirus aislados de linfosarcoma (100%), 1 en la región R y 3 en U5. Estos cambios se encontraron ausentes en la mayoría (16/22) de los provirus aislados de formas asintomáticas (AL/PL). La alta asociación entre los cambios de nucleótidos y las formas de patogenia, fue demostrada estadísticamente y permitió agrupar en forma diferencial a los provirus aislados de linfosarcoma, con respecto a los provirus de AL/PL y confirmar la existencia de una secuencia consenso de LS. Este trabajo define por primera vez la presencia de marcadores de patogenia asociados al genotipo viral de VLB así como la existencia de una secuencia de nucleótidos propia de LS en la región LTR del genoma proviral de VLB.

A promising tool to improve daily gain in pigs is the missense mutation (Asp298Asn) in the melanocortin-4 receptor (MC4R) gene, especially in the Belgian pig industry where the slow-growing Pietrain breed is very frequently used as the sire breed The MC4R is expressed in the appetite-regulating region of the brain where it regulates feed intake and energy balance. The mutation has been associated with differences in fatness, daily gain and feed intake. However, less information on the correlated effects on meat quality is available. In order to evaluate the influence of the MC4R mutation on carcass and meat quality parameters, a total of 1155 pigs of a four-way cross were slaughtered at an average live weight of 109 kg, and data about daily live-weight gain, carcass and meat quality were collected Allelic frequencies were 0.69 for the G-allele (298Asp variant or well-conserved variant) and 0.31 for the A-allele (298Asn variant or the mutated variant). Barrows and gilts were almost equally distributed in this population with, respectively, 49.9% and 50.1%. Moreover, independent of this mutation, the relationship between average daily gain (ADG) and carcass on the one hand and meat quality traits on the other hand was evaluated in this population. A significant positive influence of the MC4R mutation on ADG (P < 0.001) was found accompanied by a higher fat thickness (P < 0.05) and a lower carcass lean meat content (P < 0.01), whereas muscle thickness and carcass conformation traits were not affected. The effects on meat quality traits were not significant, except for a lower shear force (P = 0.054) and a higher intramuscular fat content (P = 0.052) in AA animals. In the longissimus, pH and pork quality meter (PQM) values were not influenced, and effects on drip loss and colour were not apparent. Residual correlation coefficients between ADG and carcass lean meat content on the one hand and meat quality traits on the other hand were generally very low (vertical bar r vertical bar > 0.1). Higher ADG, higher carcass fat thickness and lower carcass lean meat content were correlated with slightly lower shear force values (vertical bar r vertical bar similar to 0.1, P < 0.05). In conclusion, in the studied population, the Asp298Asn mutation in the MC4R gene was associated with improved daily gain, higher carcass fatness and almost no effect on meat quality traits.

Pregnancy-associated glycoproteins (PAGs) isolated from the placenta of various ruminant species are enzymatically inactive members of the aspartic proteinase family. The measurement of these proteins in the maternal blood can be a good indicator of the presence of a live embryo. As certain aspartic proteinases are present in biological fluids in physiological and pathological conditions at various concentrations, it was necessary to determine the specificity of three radioimmunoassay (RIA) systems currently used for the detection of PAG molecules. Commercially available members of the aspartic proteinase family like pepsinogen, pepsin, chymosin, rennet, cathepsin D and renin were tested in a wide concentration range (10 ng/ml - 1 mg/ml). Pepsinogen cross-reacted in RIA 1, RIA 2 and RIA 3 over 1 mg/ml, 50 microg/ml and 500 microg/ml concentrations, respectively. In the presence of pepsin, cross-reaction was observed in RIA 1, RIA 2 and RIA 3 over 1 mg/ml, 500 microg/ml and 1 mg/ml concentrations, respectively. Chymosin and rennet could cross-react in RIA 2 and RIA 3, while renin and cathepsin D did not decrease the binding of the tracer to antisera more, than that of the minimal detection limit. As the plasma/serum concentrations of the examined aspartic proteinases reported in the literature were outside the concentration range where cross-reaction was observed, it can be concluded that these RIA systems were specific for the detection of PAGs in biological fluids.

Le myélome multiple (MM) est une maladie hématologique caractérisée par la prolifération excessive de plasmocytes cancéreux au sein de la moelle osseuse. Une des caractéristiques principales de cette maladie est l’interaction entre les cellules myélomateuses et les cellules voisines situées dans la moelle. De par l’activation des cellules endothéliales, l’angiogenèse joue un rôle essentiel dans le développement du MM. Dans cet article, les processus permettant la progression du phénomène d’angiogenèse dans le MM seront abordés. Entre autres, nous identifierons les cellules interagissant avec les plasmocytes cancéreux, les cytokines influençant l’angiogenèse ou encore les protéases responsables de la dégradation de la matrice extracellulaire impliquées dans la pathologie. Finalement, l’influence du phénomène d’hypoxie (via l’expression de la protéine hypoxia-inducible factor-1) et le rôle de l’activation constitutive du Nuclear Factor-kB dans la néovascularisation seront mis en avant.
