Anisotropic muon Knight shift in the HCP single crystals of Cd, Zn and Be
1984
In single crystal samples of Zn, Cd and Be (hcp structure) stroboscopicμSR measurements successfully revealed anisotropies in the muon Knight shift (Kμ). An anisotropic Kμ can provide information on the amount of non s-electrons screening the charge of the muon implanted in these metals as a light hydrogen isotope. In Cd, the anisotropic part depends strongly on the temperature and shows a change in sign at roughly 110 K. In Zn, the anisotropic part below 10 K turns out to comprise 4th order contributions in the direction cosines of the external field. This can be understood on the basis of an anisotropicg-factor of the conduction electrons or spin-orbit coupling, respectively.
Muon Knight shift at a structural defect in zinc crystals
1984
The interaction of a light hydrogen isotope with a structural defect is traced for the first time by means of the temperature dependence of the muon Knight shiftKμ in the hcp metal Zn. A surprising result is the huge and negativeKμ (−520 ppm) at the defect site, probably a multivacancy cluster.
Muon states in metals: Recent progress
1984
We report on our results in two interesting questions related to muon spin rotation studies in condensed matter: (i) energetics of muons in metals, including lattice relaxation and zero point motion in self-trapping phenomena, and (ii) systematics of Knight shifts and hyperfine fields.
Muon Knight shift studies in single crystals of Zn and Cd
1981
Recently f i r s t resul ts have been reported on the muon Knight s h i f t in high pu r i t y (6N) spherical s ingle crys ta ls of Cd and Zn [ l ] . These measurements, using a stroboscopic ~SR-technique [2 ] , are extensions of e a r l i e r ~+ Knight s h i f t measurements in nontrans i t ion metals [3 ,4] in which the pos i t i ve muon is used as a "hydrogen" subs t i tu te in the study of i t s local e lec t ron ic s t ructure in a metal environment. Since the s o l u b i l i t y of hydrogen in these metals is general ly very small , no proton-NMR measurements have ever been performed in th is class of metals. To the extent that the mass d i f ference between the proton and the muon is…

Joannici w Łosiowie w średniowieczu
2022
Łosiów to dzisiaj wieś w województwie opolskim, w powiecie brzeskim, przy drodze z Opola do Brzegu. Jej historia jest znacznie starsza i sięga średniowiecza. Początki i rozwój tej wioski związane są z historią zakonu rycerskiego joannitów. Bracia zapisali się w historii Dolnego i Górnego Śląska na wiele stuleci, zarówno zbierając fundusze na wojny z niewiernymi, jak i przez gospodarcze eksploatowanie przyznanych im ziem, czy wreszcie służąc duchowo mieszkańcom tych dwóch regionów. Między XIII a XIV wiekiem joannici starali się zbudować wokół Łosiowa blok swoich majątków ziemskich opartych o linie Odry i nysy Kłodzkiej. Oprócz Łosiowa obejmował on opiekę nad kościołami w Wierzchu i Brzegu, m…
Frank H. Knight, pragmatism, and American institutionalism: A note
2009
This note deals with the debated question of whether, and to what extent, Frank Knight's epistemology was consistent with the general philosophy of American pragmatism. First, in accord with recent interpretations, I provide new evidence illustrating that Knight's views on science, knowledge and related philosophical topics present some important similarities with the pragmatic tradition. Second, I attempt to demonstrate that Knight's unsympathetic reading of Dewy and pragmatism was, to a relevant extent, a consequence of his aversion to the so-called scientific wing of American interwar institutionalism. © 2009 Taylor & Francis.
Il reliquiario del teschio del Beato Gerlando, Cavaliere gerosolimitano
2018
The essay, starting from a little-known work of art, the reliquary of the skull of the Blessed Gerland kept at the Diocesan Museum of Caltagirone, deepens this figure of thirteenth century knight of the Order of St John who spent part of his life in Caltagirone, Sicily. The Blessed Gerland is one of the most popular early saints and heroes of the Order, who until now has been considered of Nordic origin, in particular Polish or German.
ELITES AND ECCLESIASTICAL CAREERS IN EARLY MODERN SICILY: BISHOPS, ABBOTS AND KNIGHTS
2009
Most recent research on Sicilian aristocracy in early modern age has shown how the elite of the island, while keeping its reference “ideological” models in the titled nobility of feudality, was actually a very composite social group, formed by bureaucrats, lawyers, merchants, former “gabelloti” (major tenants of estates) as well as by professionals. Moreover, joining this heterogeneous aristocratic group was increasingly linked, especially since the end of the sixteenth century, to a large availability of financial resources provided by these “new nobles”. During that period, infact, due to mounting economical troubles, the Spanish monarchy actually made a widespread use of conferring – or,…
