Marea negra

Es tracta de simular l'efecte de la marea negra provocada per l'abocament de petroli al mar, estudiar les seves conseqüències i sensibilitzar l'alumnat envers la problemàtica de la contaminació

Morfologia i formació del complexe sinaptinèmic a espermatòcits i oòcits de Mus musculus

A method for the sequential study of synaptonemal complexes by light and electron microscopy has been used to characterize the synaptic process in mouse (Mus musculus) spermatocytes and oocytes. Pre- and post-synaptic figures can be easily identified

Assessment of the feed additives consisting of Lactiplantibacillus plantarum DSM 3676, Lactiplantibacillus plantarum DSM 3677 and Lentilactobacillus buchneri DSM 13573 for all animal species for the renewal of their authorisations (ADDCON GmbH)

Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of three additives consisting of Lactiplantibacillus plantarum DSM 3676, Lactiplantibacillus plantarum DSM 3677 and Lentilactobacillus buchneri DSM 13573, respectively, as technological additives to improve ensiling of fresh material for all animal species. The applicant provided evidence that the additives currently on the market comply with the existing conditions of authorisation. There is no new evidence that would lead the FEEDAP Panel to reconsider its previous conclusions. Thus, the Panel concludes that the additives remain safe for all animal species, consumers and the environment under the authorised conditions of use. Regarding user safety, the additives are not irritant to skin or eyes, but owing to their proteinaceous nature they should be considered respiratory sensitisers. No conclusions can be drawn on the skin sensitisation potential of the additives. There is no need for assessing the efficacy of the additives in the context of the renewal of the authorisations
