This paper investigates two topological invariants in the context of the sequence spaces Snu, which are metric topological vector spaces defined in order to study the regularity of signals. First, it extends the formula already known of the diametral dimension of spaces Snu to some non-locally pseudoconvex ones. Second, it proves that locally p-convex spaces Snu verifies the property "Omega id", which is equivalent to Omega bar for Fréchet spaces. [less ▲]

tRestoring ecosystem services in agriculture is vital to reach a sustainable food production. More specif-ically, developing farming practices which enhance biological pest control is a main issue for today’sagriculture. The aim of this study was to assess whether the two strategies of complicating the search ofhost plants by pests by increasing plant diversity, and of supporting their natural enemies by managinghabitats, could be combined simultaneously at the field scale to restore biological pest control and reducechemical insecticide use. In Gembloux (Belgium), wildflower strips (WFS) were sown within wheat cropsin which pests (i.e., aphids), their predators (i.e. aphidophagous hoverflies, lacewings and ladybeetles)and parasitoid wasps were monitored for 10 weeks in the period of May through July 2015 as indicatorsof the ES of pest control. Aphids were significantly reduced and adult hoverflies favoured in wheat inbetween WFS, compared to monoculture wheat plots. No significant differences were observed for adultlacewings, ladybeetles and parasitoids. In all treatments, very few lacewing and ladybeetle larvae wereobserved on wheat tillers. The abundance of hoverfly larvae was positively correlated with the aphid den-sity on tillers in between WFS, showing that increasing food provisions by multiplying habitats withinfields, and not only along margins, can help supporting aphidophagous hoverflies in crops. By enhancingthe ecosystem services of biological pest control, this study shows that increasing both plant diversityand managing habitats for natural enemies may reduce aphid populations, hence insecticide use. Futureresearch should continue this vein of work by quantifying the link between agricultural practices and thedelivery of ecosystem services in order to guide future measures of agricultural policies.

This chapter documents the design, management and effect of a project to promote “Scholarship of Teaching and Learning” (SoTL) among two groups of teachers at the University of Liège (Belgium). Through a combination of collective “moments” and individual tutoring, members of faculty have engaged, over the course of two years, in a process of reflection andaction targeting their feedback practices. By analyzing interviews conducted with participants, this chapter compares initial expectations built into the project by staff developers with how it actually unfolded, and how the members of faculty involved experienced it. This data outlines success factors, impediments and recommendations related to implementating this type of approach for combining individual and collective opportunities to develop aspects of SoTL.

Cet article interroge la relation entre « publics » et « collectifs » et en propose un modèle de description à caractère phénoménologique. Après un examen des implications politiques des modèles auxquels sont susceptibles de se référer les théories de la réception médiatique, on tente d’élaborer, à partir du travail de Stiegler, de Rancière et de Derrida, une approche de la réception qui permet de décrire à la fois l’émancipation et la domination, cette alternative étant l’un des points de butée des théories de la réception. Le critère déterminant est ici l’adresse, considérée comme la traduction en termes phénoménologiques de l’énonciation. La réception est alors envisagée comme une réponse à une adresse. Cette conception de l’énonciation rend compte de la dimension politique d’une réception médiatique où l’identité sociale est désormais indexée sur notre identité de destinataires de dispositifs médiatique, c’est-à-dire de publics [less ▲]

BACKGROUND AND OBJECTIVES: Patients with Prader–Willi syndrome (PWS) display poor feeding and social skills as infants and fewer hypothalamic oxytocin (OXT)-producing neurons were documented in adults. Animal data demonstrated that early treatment with OXT restores sucking after birth. Our aim is to reproduce these data in infants with PWS. METHODS: We conducted a phase 2 escalating dose study of a short course (7 days) of intranasal OXT administration. We enrolled 18 infants with PWS under 6 months old (6 infants in each step) who received 4 IU of OXT either every other day, daily, or twice daily. We investigated the tolerance and the effects on feeding and social skills and changes in circulating ghrelin and brain connectivity by functional MRI. RESULTS: No adverse events were reported. No dose effect was observed. Sucking assessed by the Neonatal Oral-Motor Scale was abnormal in all infants at baseline and normalized in 88% after treatment. The scores of Neonatal Oral-Motor Scale and videofluoroscopy of swallowing significantly decreased from 16 to 9 (P < .001) and from 18 to 12.5 (P < .001), respectively. Significant improvements in Clinical Global Impression scale scores, social withdrawal behavior, and mother–infant interactions were observed. We documented a significant increase in acylated ghrelin and connectivity of the right superior orbitofrontal network that correlated with changes in sucking and behavior. CONCLUSIONS: OXT is well tolerated in infants with PWS and improves feeding and social skills. These results open perspectives for early treatment in neurodevelopment diseases with feeding problems.

This chapter examines the dominant continuity of the EU’s transformative policy in Ukraine during the crisis in Ukraine. Natorski scrutinizes how the Euromaidan revolution, the annexation of Crimea and the war in Donbass affected the dynamics of EU policy reproduction since 2013 and explains the EU-Ukraine-Russia discussions on the potential trade consequences of the Deep and Comprehensive Free Trade Area. The dynamics of the continuity of the EU policy towards Ukraine and the altered role of Russia are explained in terms of the discursive representations of the crisis in Ukraine by the EU. The chapter concludes that the policy reproduction and change depend on what actors make of the crisis and to what extent crisis representation can be mediated coherently through the background discursive schemes.

According to Concrete Repair Manual as well as ACI 562-16 and European EN 1504-10 standards, a bond strength as a measure of adhesion is one the main feature of repair system necessary to be assessed. The most common laboratory and engineering method for bond strength evaluation is pull-off test. This is however a semi-destructive method that needs a repair in a place of measurement. Recently, the great interest in nondestructive techniques (NDT) development is noted. Impact-Echo (IE) is considered as one of the most promising methods for this purpose. In this paper, the study on the usability the IE test based on frequency spectrum analysis for bond strength evaluation is analyzed. Both Finite Element Method (FEM) simulation and experimental tests were performed in order to obtain potential relations between IE frequency spectrum and parameters characterizing concrete substrate quality that may affect the final bond strength and the real value of pull-off bond strength measured on samples as well. It was concluded that the IE method can be a useful tool for interface quality and bond strength evaluations in concrete repair system. However, more complex signal analysis, e.g. wavelet analysis, should be considered in the future. [less ▲]

The implementation of fish downstream migration bypass systems is still a major challenge, and there is interest in validating the adequacy of different configurations of bypass devices. In the Amblève River (Belgium), a mobile 3.3-m height dam feeds two principal Francis and one Francis micro-turbine and is equipped with a modern vertical slot fish pass and a downstream bypass. The aim of this study was to test the bypass attraction and efficiency (i.e. percentage of fish that approach the entrance and use the bypass) for Atlantic salmon smolts. During three consecutive years, a total of 1346 smolts were equipped with a radio frequency identification tag and released from March to May upstream of the dam of Lorcé. The entrance of the downstream migration bypass was equipped with a radio frequency identification antenna in order to detect the smolts approaching. In 2014, a capture cage was also placed downstream the bypass to evaluate its efficiency. The mean percentage of detected smolts at the entrance varied from 26.2 to 39.7%. In 2014, 16.5% of the released smolts entered the bypass and were finally caught in the cage, representing 39% of the smolts detected at the entrance. More than 98% of the detections occurred during night (mainly between 9 PM and 3 AM). The searching delay near the bypass entrance varied from less than 5 min to more than 5 days (median 4.3 min). Visual observation indicated a behavioural reluctance before entering the bypass, with a shift from positive to negative rheotaxy. Our results underline the difficulty to install retrofitted bypass system on old existing hydropower plants. Copyright © 2016 John Wiley & Sons, Ltd. [less ▲]

The aim of the present study was to determine the chemical composition and evaluate the acaricidal activity of Thymus algeriensis essential oil (TAEO) against Varroa destructor. This ectoparasitic mite is a pest of the honey bee Apis mellifera. The essential oil from the aerial parts of T. algeriensis, obtained by hydrodistillation, was obtained in a yield of 2.8± 0.2%, w/w. The TAEO was analyzed by GC and GC/MS. Thirty-four compounds were identified, representing 99.3% of the oil. The main constituents were carvacrol (48.4%), γ-terpinene (14.9%), p-cymene (14.7%), and thymol (5.6%). Four lots were constituted at the level of an apiary in order to study the dynamics of the Varroa destructor and its host, Apis mellifera. After diagnosis by the biological method "install of diapers", the lots were treated at different doses of TAEO (0.1, 0.3 and 0.5%). TAEO was sprayed on top of the hives. The results show that TAEO at 0.5% resulted in a decrease in the rate of infestation of Varroa destructor, causing a mortality rate of 32.6% without negative effect on the nesting of the queen. The essential oil of T. algeriensis could be used as a bioacaricidal agent. [less ▲]

Louise de Savoie occupies a singular place at the French royal court : neither queen nor queen-mother, but mother of the King, she nonetheless played a prominent role in the political and cultural affairs of France. Daughter of Philippe de Bresse, duc de Savoie, she was raised at the court of her aunt, Anne de France, and married in 1488 at age 11 to Charles d’Angoulême, head of a cadet branch of the royal house of Valois. At Cognac where the couple resided, she gave birth to her illustrious children, Marguerite in 1492, and François in 1494. After the sudden death of her husband in 1496, she was herself still too young to be appointed their official guardian. Obliged to share that responsibility with Louis d’Orléans who became king in 1498, the young widow nonetheless asserted her authority in their education. How she succeeded in establishing her place at court, while her son, at first a distant heir to the throne, rose to be king in 1515, can be viewed through her astute patronage of arts and letters. Keenly aware of the power of books and images, Louise multiplied commissions that would reinforce her own position and that of her family and entourage, striving to align herself with illustrious women, past and present. Identified with “Dame Prudence” as she overcame obstacles and rivals, Louise de Savoie’s tenacious devotion to her children culminated in power that was fully recognized in the appointment of « Madame » as Regent of France.
