We report on parity-violating asymmetries in the nucleon resonance region measured using inclusive inelastic scattering of 5-6 GeV longitudinally polarized electrons off an unpolarized deuterium target. These results are the first parity-violating asymmetry data in the resonance region beyond the $\Delta$ (1232). They provide a verification of quark-hadron duality - the equivalence of the quark- and hadron-based pictures of the nucleon.

By scattering of polarized electrons from the MAMI accelerator on a polarized He3 target we have determined the ratio of electric and magnetic form-factors of the neutron at intermediate momentum transfer between the low-Q values of the previous runs and the high-Q results obtained at Jefferson Lab.

We report new $p(e, e' p)\pi°$ measurements in the $ \Delta^+(1232)$ resonance at the low momentum transfer region utilizing the magnetic spectrometers of the A1 Collaboration at MAMI. The mesonic cloud dynamics are predicted to be dominant and appreciably changing in this region while the momentum transfer is sufficiently low to be able to test chiral effective field theory calculations.

In the framework of the CBM model as a characteristic representative of chiral quark models we have computed the scattering and pion electro-production amplitudes for the nucleon resonances in the region where resonances in D partial waves dominate.

Direct liquid scintillation counting (LSC) for quantification of bio-fuels content in fuels was implemented and validated on three liquid fossil fuel matrices. Fatty acid methyl esters (FAMEs), hydrogenated vegetable oil (HVO) and bio-ethanol were used as bio-fuels. The method is applicable in the range up to 100 % of bio-component .
