Existence of solutions to a higher dimensional mean-field equation on manifolds

For $m\geq 1$ we prove an existence result for the equation $$(-\Delta_g)^m u+\lambda=\lambda\frac{e^{2mu}}{\int_M e^{2mu}d\mu_g}$$ on a closed Riemannian manifold $(M,g)$ of dimension $2m$ for certain values of $\lambda$.Comment: 15 Page

Non union of the neck of radius: a case report and review of the literature

Fractures of the neck of radius are frequent in trauma. They happen without being noticed at the moment of injury of the elbow or in the context of polytrauma. A case of non union of the radius neck occurring in a young person due to ignorance, during first consultation has been reported by the authors. They insist on the rigour to be brought during the diagnosis and the treatment of the fractures of the proximal extremity of the forearm and they also propose the conservative treatment of the non union of the radius neck as a credible alternative to surgical treatment by radius head replacement or by open reduction, bone grafting and internal fixation. Key words: radial neck; fracture; non union; treatmen

West African context call for rapid implementation of insect meal fir fishmeal substitution [résumé]

Insects to Feed the World, Québec, CAN, 12-/06/2022 - 16/06/2022In West Africa, numerous economies are dependent on fisheries resources; this sector can reach almost 10% of the national gross domestic product and represents a central sector for food security as the most important animal protein for human consumption and aquafeeds. Due to overexploitation, West African fish stocks are under serious threats and massive implantation of fishmeal factories has raised serious concerns about the sustainability of small pelagic fish resources. Although this situation is well understood by many political decision-makers, this trend is not about to be reversed. Concurrently, the government of Senegal seeks to increase the production of the Senegalese fish farming industry. To address these challenges, we are investigating the possibility of harnessing the ability of black soldier fly (BSF) larvae to replace fishmeal. Given the lack of formal institutional initiatives in Northwest Africa, we initiated in 2020 a collaborative program to establish a technical platform 'Art Sunu Gueej' to develop an inter-institutional insect production unit in a controlled environment. We have identified endemic BSF populations in local piggeries as well as agricultural surpluses including millet bran, rice bran, and mango waste that could serve as BSF feedstocks, to ultimately partially replace fishmeal for aquafeed formulations. We have established an Action Plan for awareness of political decision-makers, including a research plan to: (1) optimise and adapt BSF strains for West Africa production and, (2) test insect meals for aquaculture and poultry sectors. Based on these results, we will use our new platform for fundraising and foster collaborations to promote insect meals as fishmeal replacements for aquafeeds in West Africa
