Quantum dots are fruitful systems for studying charge and spin dynamics at the single electron level. In this thesis we explore electron dynamics under strong microwave driving. This reveals a range of interesting non-equlibrium dynamics. We first study Landau-Zener-Stückelberg-Majorana (LZSM) dynamics in a single electron charge qubit. Here we observe the expected multi-photon transition fring...

If neutrino conversions within the Sun result in partial polarization of initial solar neutrino fluxes, then a new opportunity arises to observe the ¯ νe's in future neutrino experiments in the low energy region (such as BOREXINO or HELLAZ) and thus to probe the Majorana nature of the neutrinos. The νe → ¯ νe conversions may take place for low energy solar neutrinos while being unobservable at ...

Abstract Organic industrial materials are exposed to fungal deterioration; prevent this, several additives can be used. In the present work, Egyptian cotton linters, linen textile, and parchment (goat skin) provided from zones in Egypt were The application of eco-friendly essential oils (EOs) isolated Pinus rigida wood Origanum majorana green leaves linter paper pulp (CLP), as bio-fungicides pr...

With increasing demand in the field of herbal medicines and cosmetics, it has become necessary and pertinent to probe into the area of systematic knowledge about herbal drugs. There is a need for the application of this knowledge in authentification, detailed study and practical utilization of crude drugs. The present paper deals with the taxonomy, anatomy, powder study pertaining to organolept...
