[more ▼] For decades, scientific literature identifies the roles that a nonprofit board should assume, adopting too often a normative and static view on the issue. If a clear view is absolutely desirable, we refuse to endorse simplistic views on governance. Indeed, the heterogeneity of nonprofit organizations, the diversity of governance mechanisms, the fact that external and internal pressures do design governance models and the importance of time factor lead us to consider that governance models cannot be established once and for all but have to be thought in a dynamic process. The model that we present here underlies a dynamic vision of the roles and the composition of nonprofit boards.

[more ▼] In order to protect themselves against cold and to survive through the winter, the Asian ladybeetle Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) forms large aggregates inside dwellings to overwinter. In this work, the implication of hydrocarbons on the aggregative behaviour of this invasive species has been examined to understand the mechanisms involved in this particular phenomenon. The evolution of non-volatile compounds, proved to be used by H. axyridis in this phenomenon, on one hand to guide individuals to the aggregate ("trail") and on the other hand, to ensure the cohesion of the cluster ("aggregation blend"), has been studied by performing chromatographic analyses and behavioural tests. The results show that the composition of the trail deposited by individuals, and its biological activity on ladybirds, change over months. However, the change in ladybirds’ response towards these trails is not due to a modification of blend attractiveness but well to a change in the physiological state of ladybugs. Furthermore, the effect of photoperiod on the induction of that hivernation state was tested. It was highlighted that only a short photoperiod could not be responsible for the aggregation state of H. axyridis. Then, the maturing process of the aggregation blend was studied, demonstrating that saturated hydrocarbons were more persistent and suggesting their use by ladybirds to join the same aggregation sites year after year. Moreover, it turned out that cuticular hydrocarbons, as well as thigmotaxis, play a role in the aggregation behaviour of H. axyridis. However, this second factor is involved to a lesser extent.

[more ▼] The Coan epigraphical evidence to address the topic of civic priesthoods is both exceptionally large and rich. Since the publication of the Inscriptiones Graecae XII 4 in 2010, 35 inscriptions have been available, which consist of decrees of the polis regulating the sale of various priesthoods. These documents, when confronted with other types of inscriptions, such as sacrificial calendars or cult regulations, provide valuable insights into understanding the role played by the priests in the cults of the gods of the civic pantheon, as well as into the relationship between those officials and the polis which appointed them. This paper focuses on these two aspects of Coan priesthoods.

[more ▼] Complex mineralogy combined with a variable chemistry lead to various flotation responses of cobalt oxy-hydroxides present in oxidised and mixed copper-cobalt stratiform deposits of the Central African Copperbelt. Optimum metallurgical results require very high dosages of reagents and the management of such high chemicals concentrations in the pulp at the plant scale is delicate. The transition period between high reducing conditions during the sulfidisation step and a more oxidising environment prevailing during collector adsorption is particularly critical. This paper demonstrates how the use of copper and cobalt complexing agents can significantly improve the process control and metallurgical performance. The different modes of action of these reagents are presented and mechanisms for the various reactions proposed. Plant results following the introduction of ammonium sulfate at the New Concentrator of Kipushi are discussed.

[more ▼] Bacillus subtilis species are well-known and extensively-used beneficial rhizobacteria for biocontrol of plant diseases. Their interest arises from their ability to generate a broad array of bioactive metabolites among which three families of cyclic lipopeptides (CLPs). These CLPs display a huge diversity of structures and physico-chemical and biological properties which probably account for an important part of the biocontrol potential of the producing strains. Beside their antimicrobial properties, they are also involved in colonization and motility as well as in the systemic stimulation of immune system of the host plant. We summarize here the current knowledge of CLPs activities and focus on the recent findings in the context of biocontrol [less ▲] Detailed reference viewed: 111 (17 ULg)![]() Roles of Nuclear Factor-Kappab, P53, and P21/Waf1 in Daunomycin-Induced Cell Cycle Arrest and Apoptosis; ; Verlaet, Myriam et alin Journal of Pharmacology and Experimental Therapeutics (The) (2000), 295(3), 870-8 Daunomycin is a potent inducer of p53 and NF-kappaB transcription factors.

[more ▼] Consistent variations in glucose regulation across the 24-hour cycle are present in normal subjects. These diurnal variations are altered in various states of impaired glucose tolerance (aging, obesity, diabetes). Changes in insulin secretion, clearance and/or action across the day have been demonstrated. Studies in subjects receiving continuous intravenous glucose infusion have shown that major alterations of glucose tolerance occur during sleep and that sleep quality markedly influences glucose utilization. Diurnal variations in glucose tolerance result from the alternation of wake and sleep states as well as from intrinsic effects of circadian rhythmicity. The important roles of physiological variations in levels of counterregulatory hormones which are markedly dependent on sleep (i.e. growth hormone) or circadian rhythmicity (i.e. cortisol) have only begun to be appreciated. The modulatory effects of sleep and circadian rhythmicity on glucose regulation may have important clinical implications for the diagnosis and treatment of abnormalities of carbohydrate metabolism.
