Analisi sperimentale e previsione teorica basata sul peak stress method della durabilità strutturale di telai per scooter elettrici

Applicazione del PSM TETRA, del PSM con sotto-modellazione e del SED al giunto saldato di collegamento tra il canotto di sterzo e il tubolare del telaio di uno scooter elettrico in acciaio sottoposto ad un carico orizzontale applicato al perno della ruota anteriore. In aggiunta sono state effettuate delle prove al banco per carichi verticali applicati in corrispondenza della sella per la verifica della resistenza a fatica

Supplemental Data - Bioremediation of polluted air from an industrial plant using rotating biofilter reactor-based technology

Two microbial isolates (HDB, Hydrogen-Degrading Bacteria) obtained from industrial wastewater were inoculated into the rotating biofilter reactor 'Biowheel 2.0' and tested for the ability to purify gaseous flows containing benzene and non-methane volatile organic compounds (NMVOCs) released at an industrial plant. Different classes of gaseous flow were tested, namely 'cold box', 'in shell', and 'mix', all of them associated with the industrial process of 'mold-casting'. A significant increase in Removal Efficiency (RE) was recorded for benzene and NMVOCs in the inoculated 'Biowheel 2.0' biofilter, compared to uninoculated control. For each type of gaseous flow, odor impact was evaluated in the inlet and outlet flows at the industrial plant, using the test panel method and electronic nose technology. A significant drop in the amount of Olfactometric Units (O.U.) m-3 occurred in the gaseous flows treated with the bacterial consortium. The reported data demonstrate the ability of the consortium to degrade hydrocarbons, revealing its potential for bioremediation of polluted air emissions occurring at industrial plants

Understanding the molecular pathways associated with seed vigor

Farmers and growers are constantly looking for high quality seeds able to ensure uniform field establishment and increased production. Seed priming is used to induce pre-germinative metabolism and then enhance germination efficiency and crop yields. It has been hypothesized that priming treatments might also improve stress tolerance in germinating seeds, leaving a sort of 'stress memory'. However, the molecular bases of priming still need to be clarified and the identification of molecular indicators of seed vigor is nowadays a relevant goal for the basic and applied research in seed biology. It is generally acknowledged that enhanced seed vigor and successful priming depend on DNA repair mechanisms, activated during imbibition. The complexity of the networks of DNA damage control/repair functions has been only partially elucidated in plants and the specific literature that address seeds remains scanty. The DNA repair pathways hereby described (Nucleotide and Base Excision Repair, Non-Homologous End Joining, Homologous Recombination) play specific roles, all of them being critical to ensure genome stability. This review also focuses on some novel regulatory mechanisms of DNA repair (chromatin remodeling and small RNAs) while the possible use of telomere sequences as markers of aging in seed banks is discussed. The significant contribution provided by Electron Paramagnetic Resonance in elucidating the kinetics of seed aging, in terms of free radical profiles and membrane integrity is reported

Mutation breeding in Petunia: ottimizzazione di parametri chiave, rigenerazione in vitro e screening di nuove varietà

Ionizing radiation, a source of genetic variability, is used in association with in vitro regeneration to develop novel plant varieties with improved traits (Mutation Breeding). Protocols currently available need to be improved in order to increase mutation frequency and enhance commercial exploitation. Within this context, we have carried out an investigation aimed at obtaining optimised protocols based on gamma-ray mutagenesis with the final goal of producing novel Petunia per hybrids varieties, starting from commercially relevant genotype
