ln the superovulated ewe, previous studies have shown that GnRH agonist and antagonist pre-treatment improve embryo production. Consequently, an experiment on this subject was continued in order to simplify GnRH antagonist pretreatment in the ewe, and evaluate the efficiency of this technique in the superovulated goal. For the simplification of the pre-treatment, we compared the efficiency of the multiple low-dose (11' O.5mg/ day) antagonist regimen with a regimen of three injections of 1.5, 0.5, and O.5mgat 5 day intervals. The three injections regimen allowed a high ovulatory response, but a lower yield of transferable embryos (12 vs 8.3 ; P=O.08). GnRH agonist (Decapeptyl) and antagonist (Antarelix) pre-treatments were evaluated in superovulated goats. ln GnRH agonist treated goats (Decapeptyl1.8mg 22days before FSH) follicle number >3 mm was decreased (5.5 before vs 1.1 after treatment ; P<O.Ol) without an effect on the number of small follicles (2-3mm) and ovulatory response. Percentages of recovered and fertilised ova were significantly lower after Decapeptyl pre-treatment than without pre-treatment. Consequently a low number of transferable embryos per Decapeptyl treated goat was obtained (Decapeptyl + FSH: 2.2 vs FSH 4.7 ; P>O.l0). ln GnRH antagonist treated goats (Antarelix Il' 0.5mg / day before FSH) a decrease in follicle number >5 mm was observed as weIl as an increase in small follicle number (2-3mm) and ovulatory response after FSH treatment. However, this beneficial effect on ovulatory response was cancelled by an increase in the percentage of unfertilised ova and degenerated embryos. Consequently, in Antarelix treated goats the yield of embryo production was reduced (Antarelix +FSH 2.3 vs FSH 8.1 ; P<O.Ol). After in vitro fertilisation, the cleavage rate was also lower after Antarelix pre-treatment compared to the control group (84% vs 94%; P<O.Ol). However, this percentage was high (84%) as compared to the in vivo fertilisation rate (29%).A negative effect of Antarelix pre-treament on goat oocytequality is possible; nevertheless, transport and survival of spermatozoa in the genital tract are most probably affected in these conditions [less ▲]

The objective of the work consists to develop a non-destructive fruit firmness measurement. The tactile sensor technology was chosen. The force measurement acting between the fruit-sensor as well as the contact area are coupled with other meaqsurements, like the color of the fruit. The results of the measurements are compared with the firmness reference values (Magness-Taylor test) and also with the acoustic impulse response technique. Several parameters correlated with firmness are proposed. [less ▲]

A long-term survey of the P. oceanica meadow has been in progress since 1975 in the Revallata Bay (Corsica, France) (e.g.Bay, 1984). Actually, since 1991, biometric parameters of the meadow have been monitored regularly (Gobert et al., 1995). The seasonal, interannual and long term changes of these Posidonia characteristics are analysed regarding meteorological (e.g.sun, rain, temperature..)and anthropologic events such as tourism and nutrient enriched effluents in the area. Our results have pointed out the good health status of the meadow in spite of some ecological modifications linked to the increasing water temperature (Gobert et al., in press). Recent aerial photos have shown a modification of the covering surface of the meadow. An accurate studyof causes of the distribution modifications is beginning. Using our long term background data on the meadow, we are developing a transplantation technique of P. oceanica shoots using semi-artificial substrates (EAT:electrochemical accretion technology) (Van Treeck and Schuhmacher, 1998) with the aim of providing a guideline-report based on model case studies representative for many threatened Mediterranean areas.

This paper presents the results of the investigation of the biological activity that takes place in four municipal solid waste landfills situated in different regions of two dry climate countries i.e. Haiti and Tunisia. Since the climatic water balance is negative (potential evapotranspiration being 1.5 to 5 times higher than rainfall), it has often been considered that this kind of landfill has neither environmental impact nor efficient biological activity. However, the four landfills revealed a biological activity with biogas often containing more than 60 percent of methane. Indeed, under the upper waste layer that was effectively dry (dry weight from 85 to 98 %), the core of refuse contained between 35 and 65 % of dry matter. In some boreholes, the produced gases periodically expelled leachates like small geysers. Therefore, the results assess that landfill management in countries with dry climate should be considered with adapted technologies, not necessary the same as under temperate or humid climates [less ▲]

Quantitative determination of total and individual glucosinolate contents in Brassica samples (rapeseed/canola, broccoli, cabbage, mustard…) is generally realised according to the reference method ISO 9167-1. After extraction, glucosinolates are purified, then desulfated by Helix pomatia sulfatase. The desulfo-glucosinolates (DSGSL) formed are then separated by reverse phase chromatography associated with UV detection (229 nm). As each compound can possess a very different molar extinction coefficient, it is important - on a quantitative point of view - to define accurately relative response factors. The response factors actually used in the official method have been determined experimentally through indirect methods and have been fixed, some years ago, by consensus between the various laboratories who took part in a ring test. They may need to be revised and calculated for a broader panel of glucosinolates. [less ▲]

A three-dimensional coupled biogeochemical-hydrodynamical model has been developed to get a better understanding of the biogeochemical functioning of the Black Sea. The in?uence on the ecodynamics of hydrodynamical and biogeochemical processes is quantified. Nitrogen inputs from the rivers, from the sediments and from the deep sea are estimated and compared in terms of potential fertilization. The exchanges between the north-western shelf and the deep sea are quantified. The results illustrate a highly complex spatial variability of the phytoplankton annual cycle and thus, stress the importance of using a 3D model to capture the essential physical-biological interactions that explain the data.

The University of Mining and Geology in Sofia as a unique academic Institution engaged in training graduates to work in the field of mining and geological prospecting faces the need for modification and updating its curriculum, for being able to meet the challenges of European educational standards like Institution accreditation, ECTS, etc. In a smaller scale, this is particularly relevant to the Department of Mineral Processing which is one of the largest Departments (in the University) and is engaged in training students for the entire raw materials (non-petroleum) industry: ores, coal and industrial minerals. Despite the drastic reduction in great number undergraduate specialisations, the specialization “Mineral Processing” remains in the Governmental Register released by the Ministry of Education, Science and Technologies. Therefore in this new situation, there is a necessity to verify and to parallel the existing syllabus to the one practiced in a similar Departments in the EU countries and more precisely to develop undergraduate and graduate courses to include risk and hazard assessment, environmental protection and related matters.

The brain must be capable of achieving extraordinarily precise sub-milisecond timing with imprecise neural hardware. We discuss how this might be possible using synfire chains (Abeles, 1991) and present a synfire chain learning algorithm for a sparsely-distributed network of spiking neurons (Sougné, 1999). Surprisingly, we show that this learning is not subject to catastrophic interference, a problem that plagues many standard connectionist networks. We show that the forgetting of synfire chains in this type of network closely resembles the classing forgetting pattern described by Barnes [less ▲]

every commercial steel product in varying amounts. Since inclusions significantly influence properties and behaviour of materials and at the same time give indications on the quality of the steel, it is quite interesting to precise their nature and their origin. In this paper concerning a project involved in the COST 517 framework, studied alloys are high alloy steels. The raw materials were obtained from the conventionally electrical cast ingot and the Electro Slag Refining processes. The purpose is to compare various inclusions produced by these different processes and their effect on the mechanical properties. The raw material because of the melting processes themselves, leads to a product with a good to a great cleanliness, and tiny inclusions, which are haphazardly distributed. The actual ASTM E45 chart seems to be inappropriate, as the inclusions founded are too small in size. Therefore, we manage to develop a specific procedure for the study of such inclusions. The different types of inclusions encountered are oxides, titanium nitrides, and manganese sulphides. Studying the effect on mechanical properties, oxides often seem to initiate fatigue fracture.

Surface and internal quality of continuous cast products depends very much upon the behaviour of the strand in the mould. Among the parameters likely to influence this behaviour, the mould taper takes a prominent part. In order to understand better the influence of this parameter, we have build up a thermo-mechanical finite element model. the model includes an elasto-visco-plastic law to describe the behaviour of steel from liquid to solid state, a thermo-mechanical element that takes into account thermal expansion and mechanical behaviour of the strand, a unilateral contact element, a mobile rigid boundary element to model the mould and its taper and an adapted loading element to model the ferrostatic pressure according to the liquid or solid state.

La pédomorphose est un processus évolutif impliquant la rétention de caractères larvaires chez l’adulte reproducteur. Chez les salamandres et les tritons, la pédomorphose peut être facultative. Ainsi, dans une même population, alors que certaines larves atteignent la maturité tout en conservant leurs attributs larvaires (fentes branchiales, branchies), d’autres se métamorphosent en juvéniles qui atteindront leur maturité en phase terrestre avant de retourner à l’eau. Il s’agit ainsi de ce que certains dénomment une néoténie. La coexistence des deux formes alternatives adultes – les pédomorphes et les métamorphes – offre dès lors la possibilité d’examiner l’aspect adaptatif du polymorphisme et de valider les hypothèses évolutives relatives à la pédomorphose. A cette fin, plusieurs populations pédomorphiques du triton alpestre (Triturus alpestris) de France, d’Italie et de Grèce ont été étudiées entre 1996 et 2000. Un accent particulier a été mis dans la détermination des structures d’âge, du régime alimentaire et de l’occupation de l’espace. Des expériences de laboratoire ont également permis d’analyser la performance de la structure trophique des tritons et de caractériser l’effet de paramètres environnementaux sur la pédomorphose. Ces analyses montrent que les deux formes alternatives ont des structures d’âge similaires dans certaines populations (processus néoténique) alors que les pédomorphes acquièrent leur maturité plus précocement que les métamorphes dans d’autres populations (processus progénétique). La progenèse était observée dans des milieux instables. Le régime alimentaire des deux formes différait nettement dans trois lacs alpins. Les pédomorphes se comportaient comme des planctonophages tandis que les métamorphes ingéraient dans l’eau des proies exogènes au milieu aquatique. L’occupation de l’habitat n’était pas identique. La différence de régime peut être expliquée par une différence de performance de leur structure trophique : les pédomorphes étant plus performants dans la capture du plancton tandis que les métamorphes, eux, le sont dans la capture d’invertébrés terrestres. Les expériences de laboratoire ont aussi montré que l’absence de proies et l’assèchement du milieu induisaient la métamorphose. En conclusion, la pédomorphose facultative offre différents avantages qui ne sont pas nécessairement identiques dans tous les milieux. Elle est adaptative en conférant une maturité précoce dans des milieux imprévisibles et une utilisation optimale des ressources dans des habitats hétérogènes. Un tel processus est également un polyphénisme permettant un changement de tactique (métamorphose) en cas de détérioration de l’habitat. [less ▲]

The paper discusses the ability of recognition models to classify malodours in the environment three years after their calibration, with the same sources releasing odours. Two methodologies applicable either in the lab or in the field are used. The effect of the long term drift of the sensors is highlighted on the results of principal component analysis and of discriminant function analysis. The paper examines also the applicability of some drift counteraction methods proposed in the literature. Handled with some care, a correction based on the drift direction in the principal components subspace should be applicable to the classification of real odorous sources in the field. [less ▲]

In the wider framework of the search for the alternatives for the preventive use of antobiotics, the present experiments have shown that inulin could interfere in vitro with the adhesion of a pathogenic coliform to the intestinal porcine mucosa. Moreover, a first immunization experiment pointed towards a systemic specific immunomodulation (increase in IgA and IgM titres) by inulin after a boost with intramuscularly injected bovine thyroglobulin (BT).
