In this work, we investigated aroma volatiles emanated by dry roots, stems, leaves, flowers, and fruits of Cardariadraba (L.) Desv. growing wild in Tunisia and its aerial part essential oils (EOs) composition. A total of 37 volatileorganic compounds (96.7%–98.9%) were identified;4 esters, 4 alcohols, 7 hydrocarbons, 12 aldehydes, 5 ketones,1 lactone, 1 organosulfur compound, 2 organonitrogen compounds, and 1 acid. The hydrocarbons form the maingroup, representing 49.5%–84.6% of the total detected volatiles. The main constituent was 2,2,4,6,6-pentamethylheptane(44.5%–76.2%) reaching the highest relative percentages. Forty-two compounds were determined in thetwo fractions of EOs, representing 98.8% and 97.2% of the total oil composition, respectively. The principal componentswere hexadecanoic acid (34.6%), 6-methyl-5-hepten-2-one (18.3%), decanal (15.0%), 6,10,14-trimethyl-2-pentadecanone (13.2%), and n-pentacosane (13%). Micromorphological details of the leaf and stem epidermisusing light microscopy revealed polygonal cells with sinuous walls in the adaxial and abaxial leaf surfaces andnearly rectangular and long ones with linear and thick walls for the stem epidermis. The stomata complexes wereanisocytic in the leaf epidermis and mainly anisocytic and rarely paracytic in the stem epidermis. Non-glandulartrichomes were unbranched and long with an acute apex or short with a convex apex. The glandular ones wereidentified for the first time in this species. They were short-stalked with a large secretory head. The highest stomatalindex (17.02%) was recorded in the abaxial leaf surface. The identification of headspace volatiles and essentialoil compounds can be used to characterize this species, and the various epidermis micromorphologicalfeatures are very useful for biosystematics taxonomic studies within Brassicaceae.

An Original Didactic of the Standard Model “The Particle’s Geometric Model” (Nucleons and K-Mesons)

引用

Journal of High Energy Physics, Gravitation and Cosmology 2024年第3期10卷 1054-1078页

作者： Giovanni guido Abele Bianchi Gianluigi Filippelli External Contact Referent of the EEE Project at the High Scholl C. Cavalleri Parabiago Italy External Contact Referent of the Extreme Energy Events (EEE) Project at the High Scholls Gandini Lodi Italy Astronomic Observatory Brera Milan Italy

This paper shows a didactic model (PGM), and not only, but representative of the Hadrons described in the Standard Model (SM). In this model, particles are represented by structures corresponding to geometric shapes of coupled quantum oscillators (IQuO). By the properties of IQuO one can define the electric charge and that of color of quarks. Showing the “aurea” (golden) triangular shape of all quarks, we manage to represent the geometric combinations of the nucleons, light mesons, and K-mesons. By the geometric shape of W-bosons, we represent the weak decay of pions and charged Kaons and neutral, highlighting in geometric terms the possibilities of decay in two and three pions of neutral Kaon and the transition to anti-Kaon. In conclusion, from this didactic representation, an in-depth and exhaustive phenomenology of hadrons emerges, which even manages to resolve some problematic aspects of the SM.

An Original Didactic about Standard Model (Geometric Model of Particle: The Quarks)

Journal of High Energy Physics, Gravitation and Cosmology 2024年第2期10卷 854-874页

作者： Giovanni guido Abele Bianchi Gianluigi Filippelli High Scholl “ C. Cavalleri&#8221 Parabiago (Milan) Italy High Scholls “ Gandini&#8221 Lodi Italy INAF Astronomic Observatory “ Brera&#8221 Milan Italy

This work shows a didactic model representative of the quarks described in the Standard Model (SM). In the model, particles are represented by structures corresponding to geometric shapes of coupled quantum oscillators (GMP). From these didactic hypotheses emerges an in-depth phenomenology of particles (quarks) fully compatible with that of SM, showing, besides, that the number of possible quarks is six.

中-晚三叠世是现代型生态系统构建的关键时期,系统研究该时期生物与环境的协同演变过程对揭示生物复苏机制和生态系统重建规律具有重要意义.琥珀是探讨中-晚三叠世植物演化和古气候演变的重要载体.对青岩剖面雷打坡段的琥珀和伴生的植物化石开展研究,并将全球的中-晚三叠世琥珀的分布与湿润事件进行对比分析.结果发现青岩琥珀是由松柏类植物伏脂杉生产,琥珀的出现与松柏类植物的辐射演化有关.菊石生物地层表明含有琥珀的地层属于中三叠世安尼期Pelsonian亚期.认为琥珀的产出与湿润事件具有对应性,说明湿润事件可能是中-晚三叠世琥珀频繁出现的重要原因.
