Dans le jeune État belge fragilisé par son statut international, l'innovation technique constitue une priorité étatique, mais aussi un des moteurs du développement entrepreneurial. L'essor industriel du 19e s. s'accompagne ainsi d'une course à l'innovation qui sous-tend de nombreux enjeux. Cette thèse les questionne en parcourant, dans un premier temps, le territoire codifié de la propriété industrielle. L'étude porte d'abord sur la construction d'un système belge des brevets. Comment est-il conçu par les premiers gouvernements belges ? Quelles sont ses caractéristiques ? Comment favorise-t-il la course à l'innovation ? Il convient d'appréhender d'abord les cadres juridiques, les références et les singularités qui définissent l'expérience belge. Ensuite, la nature de l'adhésion des acteurs au système est analysée. Dans un second temps, l'interrogation privilégie une approche sectorielle. La relation liant les brevets à l'innovation est examinée à travers le cas de l'industrie belge du zinc et de l'entreprise qui la domine : la s.a. des Mines et Fonderies de zinc de la Vieille-Montagne, première multinationale d'Europe. Que révèlent les brevets à propos des technologies en place et de leur évolution ? Par quels mécanismes contribuent-ils à l'innovation ? L'analyse porte sur un corpus de plus de 200 brevets étudiés à la lumière des archives d'entreprises. Elle éclaire sur les processus innovants et les conditions de leur déploiement. Cette histoire technique de la filière du zinc illustre les dynamiques qui s'attachent à l'innovation au temps de l'essor industriel. Elle met en lumière un ensemble de stratégies mises en œuvre par les industriels pour contourner les problèmes que pose la technologie en place : imperfection des méthodes de réduction, nuisances, mécanisation, diversification, etc. comme les tâtonnements, hésitations, échecs, ruptures inhérents aux processus innovants.

An inquiry was carried out to assess the concentrations of plasma metabolites related to bone remodelling in 21 saddle horses of Warmblood breed aged 4-26 years, five draught horses of Ardennes breed aged 4-10 years, and 10 Ardennes foals aged 9-11 months. They were fed according to normal feeding practice in Belgium. The changes in some bone remodelling plasma metabolite concentrations were studied when an unbalanced diet was offered and later corrected for four Warmblood horses. Bone formation was evaluated by bone alkaline phosphatase (BALP), total alkaline phosphatase (TALP) and osteocalcin (bone gla-protein, OC). Bone resorption was assessed by hydroxyproline (HYP). Total calcium, ionized calcium, phosphorus (P) and 25-hydroxyvitamin D3 [25-(OH)D] concentrations were more or less constant. The comparison of four bone remodelling factors between the Ardennes and Warmblood horses showed higher concentrations in the Ardennes breed. Bone marker concentrations decreased according to age. The correction of the unbalanced Ca : P diet induced inconsistent effects at plasma level. The interpretation of the different bone parameters appeared to be difficult if not associated with other parameters such as a complete anamnesis and clinical examination of the animal in addition to dietary evaluation.

I discuss the role of women and erōs in court poetry, by focusing on the ruling pair, i.e. the couple par excellence, and arguing that a gentle, reciprocal love within the bonds of marriage is presented as a crucial value, ensuring wealth and social order as well as the continuity of the dynasty itself. Because court life is a fashionable source of models for the elite, the poetic motif of requited love also influences the ideal depiction of love outside the ruling pair. After focusing on how internal patterns of relationship between characters shape the role of the queen in Alexandrian court poetry, I turn to non-literary, epigraphic evidence, in order to show how poetic representations of royal love integrate into a wider ideological program. Although my study mainly concerns Ptolemaic ruling pairs, I discuss some epigraphic parallels from the Seleucid dynasty as well, so that some general observations can be made on early Hellenistic queenship.

The aim of this laboratory experiment was to examine courtship behavior and reproductive success under two different perceived male densities ill the Alpine newt (Triturus alpestris). Male behavioral patterns were similar at unbiased and male-biased operational sex ratios (OSR). Although the exhibition of hiring behaviors is risky in the presence of other males, no difference in the frequencies of displays was found at the two male, densities. Similarly, the responsiveness of females towards males and the Success rate of the encounters (i.e. spermatophore transfer) were not explained by file OSR. Our results show that courting Alphine newts do not change their courtship patterns when other males are present and do not interact directly. However they are not necessarily opposed to those of previous experiments showing sexual interference awl ,female aversion in male-biased OSR with possibility of interactions. These observations suggest that the evolution of courtship behavior may not be driven by the risk of sexual interference with other males prior to potential physical contact and that the benefits of breeding regardless of OSR can overcome the risk of Competition at male-biased OSR.

Environmental factors are known to have a major effect on behavioral patterns of organisms. Among these factors, temperature particularly affects ectotherms. However, although many studies focused on acoustic communication, the effect of environmental temperature on visual courtship displays and sexual performance has been little explored. The aim of this work was to determine the effect of temperature on the sexual behaviour of the Alpine newt Triturus alpestris in controlled laboratory conditions. Temperature had a major effect on the two sexes: at low temperatures, the frequencies of several displays, including sperm deposition, is lowered. This variation is in fact caused by the female responsiveness, which is temperature-dependent. However, some other behaviours, such as the fanning movement of the male’s tail (i.e., the main courtship display) are directly dependent on temperature: at lower temperatures, the tail beats at a lower rate but for a longer time. The similar reproductive success at the two temperatures indicates that breeding in cold water is not necessarily costly. It allows males and females to mate early in the season. This is particularly adaptive because, in many habitats, the reproductive period is shortened by drying or freezing conditions which may impair survival of branchiate offspring. [less ▲]

Cost related to insulin therapy is markedly increasing in Belgium, as in other Eucopean countries. In the present paper, we will briefly analyze the main reasons for such aa increase, integrate such observation withIn the global context of diabetes management and suggest some solutions to provide best care to insulin-treated diabetic patients at a reasonable cost. The rise of the cost of insulin therapy has a multifactorial origin. It mainly results from an increase in the number of diabetic patients, a more intensive management, In both type 1 and type 2 diabetes, and a greater use of more expansive insulin analogues. It is important to analyze the increase of the cost of insulin therapy within the global burden of diabetes melitus. Only a better responsibility of all health care partners, patients, physicians, pharmaceutical companies, public health authorities, could provide solutions allowing diabetic people to profit from best treatments they should receive in order to prevent diabetic complications, by far the main cause of expenses.
