The Ottoman state and descendants of the prophet in Anatolia and the Balkans (c. 1500-1700)
Throughout the Islamic world those claiming descent from the Prophet Muhammad (T. seyyid/serif pl. sadat/esraf) were (and are) accorded a special status. This article shows that the process of teseyyud ("seyyidization") not only took place through official awards, but also through appropriation. In the Ottoman Empire registers thus began to be kept of officially recognized sadat. The examination of these, largely un(der)studied, sources argues that the state sometimes employed its capacity to seyyidize for (cultural) political purposes. The article also sheds valuable light on Ottoman policies vis-a-vis tribalism and nomadism
Multiwavelength Mass Comparisons of the z~0.3 CNOC Cluster Sample
Results are presented from a detailed analysis of optical and X-ray
observations of moderate-redshift galaxy clusters from the Canadian Network for
Observational Cosmology (CNOC) subsample of the EMSS. The combination of
extensive optical and deep X-ray observations of these clusters make them ideal
candidates for multiwavelength mass comparison studies. X-ray surface
brightness profiles of 14 clusters with 0.17<z<0.55 are constructed from
Chandra observations and fit to single and double beta-models. Spatially
resolved temperature analysis is performed, indicating that five of the
clusters in this sample exhibit temperature gradients within their inner 60-200
kpc. Integrated spectra extracted within R_2500 provide temperature, abundance,
and luminosity information. Under assumptions of hydrostatic equilibrium and
spherical symmetry, we derive gas and total masses within R_2500 and R_200. We
find an average gas mass fraction within R_200 of 0.136 +/- 0.004, resulting in
Omega_m=0.28 +/- 0.01 (formal error). We also derive dynamical masses for these
clusters to R_200. We find no systematic bias between X-ray and dynamical
methods across the sample, with an average M(dyn)/M(X-ray) = 0.97 +/- 0.05. We
also compare X-ray masses to weak lensing mass estimates of a subset of our
sample, resulting in a weighted average of M(lens)/M(X-ray) of 0.99 +/- 0.07.
We investigate X-ray scaling relationships and find powerlaw slopes which are
slightly steeper than the predictions of self-similar models, with an E(z)^(-1)
Lx-Tx slope of 2.4 +/- 0.2 and an E(z) M_2500-Tx slope of 1.7 +/- 0.1.
Relationships between red-sequence optical richness (B_gc,red) and global
cluster X-ray properties (Tx, Lx and M_2500) are also examined and fitted.Comment: Astrophysical Journal, 48 pages, 11 figures, LaTeX. Added correction

Mer’āt-e vāredāt : tārīḫ-e soqūṭ-e Ṣafaviyān, peyāmad-hā-ye ān va farmānravā’ī-ye Malek Maḥmūd Sīstānī. Éd. Manṣūr Ṣefatgol, Tehrān, Mīrāṯ-e Maktūb, 1383/2004, 293 p., index, bibliographie.
Publication d’une source capitale pour la fin de la période safavide, due à un auteur issu d’une famille de seyyed de Téhéran émigrée en Inde à l’époque de l’Empereur Awrangzeb (r. 1658-1707). Cette chronique était restée presque totalement inconnue, notamment de L. Lockhart dans son travail de référence (The Fall of the Safavid Dynasty and the Afghan Occupation of Persia, Cambridge 1958), et ceci malgré le fait que des copies soient répertoriées dans les bibliothèques britanniques (où elles ..
The Relation between Packing Effects and Solid State Fluorescence of Dyes
The solid state fluorescence of diketopyrrolopyrrole dyes and perylene-3,4:9,10- tetracarboxylic bisimides with alkyl substituents are investigated and compared with noncovalent interactions. The latter are estimated by crystal structure analysis, heats and entropies of fusion and solubilities in organic solvents. Applications of the dyes are discussed
Atlas of electron content values observed at Urbana, Illinois, 1 December 1967 - 30 December 1970
Ionospheric electron content versus local time data deduced from Faraday rotation observations of ATS-III geostationary satellite signals at Urbana, Illinois are reported. The data are presented in two forms. Values of subionospheric latitude (SILAT) and subionospheric longitude (SILON) are in degrees north and degrees west, respectively. These are computed on the basis of 350 km for the mean ionospheric height, which value is also used for the calculation of the geometric-magnetic factor, required for the conversion of the measured Faraday rotation angle to electron content. Entries of zero for the electron content in the tables represent no data for those times
