En esta tesis se han estudiado los imanes moleculares (SMM o Single Molecule Magnets en inglés) como potenciales candidatos para formar parte del procesador de un ordenador cuántico. En concreto, moléculas compuestas por uno, dos o tres iones que actúan como qubits. Por otro lado, se ha desarrollado una nueva generación de microsusceptómetros SQUID de 30 µm de diámetro que ha permitido estudiar el comportamiento de muestras de tamaño nanométrico como un primer paso para verificar el comportamiento de estos SMM aislados de su medio cristalino.
In this thesis, we have developed quantitative and qualitative studies of the magnetic states of different magnetic nanostructures by in situ Lorentz Microscopy (LM) and Electron Holography (EH) experiments under application of magnetic field or working at low temperature (100 K), on three different magnetic nanostructures: L-shape Co and Co50Fe50 nanowires, Co antidot arrays and strained La2/3Ca1/3MnO3. DW manipulation experiments by magnetic field allowed characterize process such as DW nucleation, propagation, pinning and depinning in the nanowires. By in situ LM, remanent magnetic states and reversal magnetization process in high-density antidot arrays were studied. Finally, the effect of the substrate-induced strain in LCMO thin film were studied by EH at 100 K. We found that such strain effect produce a magnetic phase separation and/or variation in the magnetocrystalline anisotropy.
Thirty different health professions are currently regulated in law on a UK-wide basis by nine regulatory bodies and regulation of pharmacy technicians will also become mandatory from July 2011. The Health and Social Care Act 2008 initiated a series of reforms to the governance of the health professions regulatory bodies, delivering a fundamental change in the governance of the regulatory bodies, ending professional control over their governing councils and strengthening the contribution of lay members. Delivering safe and effective care will continue to be the driving principle behind professional regulation. Further, in the context of "any willing provider" being able to provide services to...

When father-of-two Sam loses his job, he (reluctantly) agrees to stay at home while his wife returns to work. Secretly thinking this whole parenthood thing a breeze of leisurely jaunts to the park, reading the paper while the children play quietly and occasionally attending a civilised play date or two, Sam quickly realises just what exactly it means to be a stay-at-home parent. Inevitably, domestic mayhem ensues. Just trying to get dressed in the morning and out of the house without going to A&E is a feat, as is managing the children's complicated play-date schedule while fending off the unwelcome advances of Jodhpur Mum at the playground. And Sam's foolproof 72-step Childcare Programme doesn't seem remotely up to the task. Desperate to get his life back on track, Sam seizes upon a variety of mad schemes, but just as things look like they're beginning to fall into place, he makes a very surprising discovery ...
Diary of a Humiliated Man presents 8 months in the life of a hopelessly banal individual-told in the form of notebook entries.
