A quel type de jeu tu joues ? Quelques catégorisations de Wolfenstein 3D dans la perspective des communautés de joueurs
Get PDFpeer reviewedWith the emergence of web 2.0, communities of players have gained an enhanced possibility to talk about the categorisation of video games, opposing their discourses with that of the industry. This way of categorising works, by co-constructing categories among internet users, shows new means to divide games into groups meaningful to the players (against the categorisation practiced by researchers, which often makes sense only to the sole researchers, because it is generally based on formal criteria). In this communication, I will exemplify the variety of categorisations considered by the players by exploring the case of Wolfenstein 3D, which seems a pretty straightforward work, but hides a few particularities ignored by scholars. For example, players do not only consider it as the father of the FPS (which can be problematic, because the term didn’t exist in 1992), but also as a game of a certain era, on a certain support or with technical aspects proper to games

Get PDFAddressing variability in Hermetia illucens bioassays: have all the key species-specific parameters been identified?
Get PDFeditorial reviewedLaboratory research on organisms is challenging due to numerous abiotic and biotic factors that must be controlled. The black soldier fly (Hermetia illucens) is no exception, and these factors can affect result repeatability—between research teams, experiments by the same team, and even replicates of a single experiment. While some factors like temperature and humidity are well known, variability sometimes remains unpredictable, leading to trends without statistical significance. This suggests that key species-specific parameters remain unidentified. In this context, we investigated two such parameters. The first relates to the dynamics of oviposition. In breeding cages, eggs are laid over several days, potentially producing multiple cohorts of larvae with distinct characteristics such as growth, survival, or sex ratio. The second concerns larval composition. As larvae stop feeding at the end of development, they progressively empty their digestive tracts. Collected samples therefore include individuals with varying levels of intestinal content, affecting their nutritional profile. Our work aims to better identify such influential parameters to improve experimental consistency. By refining our understanding of H. illucens biology, we contribute to the development of a more reliable and repeatable experimental model for this promising species

Effects of a mealworm larvae-based diet on laying performance and egg quality in laying hens
Get PDFpeer reviewedSoybean meal, the cornerstone of poultry nutrition, is increasingly scrutinized due to its heavy reliance on imported and genetically modified (GMO) crops, raising concerns about sustainability, cost, and compatibility with organic production systems. This challenge has spurred the search for alternative protein sources, with insect meals emerging as a promising solution. Among them, the yellow mealworm (Tenebrio molitor) offers a nutrient-dense, environmentally sustainable feed ingredient rich in proteins, lipids, and bioactive compounds. This study investigated the effects of dietary inclusion of T. molitor larvae on the performance and egg quality of laying hens. Thirty-six Isa-Brown hens (40 weeks old) were assigned to four dietary treatments: a control diet and diets supplemented with 1%, 2%, or 4% mealworm larvae (TM1, TM2, TM4). Over a four-week period, laying rate, feed conversion ratio (FCR), and egg quality traits (physical parameters, shell integrity, yolk cholesterol, and fatty acid composition) were measured. Results revealed that while laying performance remained unaffected (P = 0.48), hens in the TM4 group achieved significantly improved FCR (P = 0.03). Importantly, no adverse effects were observed on egg weight, shell quality, or nutritional composition. These findings demonstrate that moderate supplementation with T. molitor can enhance feed efficiency while maintaining egg quality, positioning insect proteins as a viable pathway toward more sustainable and resilient poultry production
Enhanced Extraction through Microwave-Assisted Technologies: Exploring New Analytical Frontiers
No full textpeer reviewedMicrowave-assisted extraction (MAE) has gained increasing attention as a rapid, efficient, and eco-friendly technique for isolating target compounds from complex matrices. This project aims to develop microwave-assisted extraction methods to optimize extraction efficiency, minimize solvent consumption, and reduce sample preparation time.
The versatility of this technology could be applied to increase the extraction efficiency, to perform rapid saponification, and to combine different separation steps as saponification + extraction, or extraction+derivatization, particularly thanks to the use of a close system that allow to increase the temperature over the boiling point of the solvent avoiding losses of volatiles . The validity of methods has been proven for FAMEs, Sterols, and MOSH&MOAH.
More recently, a new system incorporating high pressure has opened new perspectives, allowing to significantly reduce the solvent volume used, while at the same time offering an inert environment to avoid oxidation of sensitive compounds. Moreover, some preliminary trials have been performed to convert the system to supercritical fluid extraction, using CO2. . If successful, this prototype could offer a more sustainable alternative to traditional extraction techniques, aligning with the principles of green analytical chemistry and providing new solutions for complex analytical challenges
