Aspects of the Romano-British landscape around holme on Spalding moor, east Yorkshire
No full textAn examination was undertaken of the nature and extent of Romano-British settlement and industry in the context of the landscape around Holme on Spalding Moor. An environmental reconstruction of the study area was made, showing it to be marginal, low lying and prone to wetness. The most suitable land for exploitation were the ridges of Aeolian sands. Systematic field survey over an 8 x 8 km square, together with cropmark evidence showed that site distribution was closely related to soil type, watercourses and other environmental constraints. A total of 106 Romano-British kiln and settlement sites, 49 sites with iron working or manufacture and several with evidence for glass working were discovered from fieldwalking, examination of museum collections and archives and excavations. Worked flints and stone axes showed that there had been activity on the sand ridges near to watercourses since the Neolithic. The data suggests that settlement was intensified during the later Iron Age with iron working and manufacture being undertaken especially near the dendritic creek system in which the Hasholme Iron Age log boat sank. The Romano-British pottery industry seems to have built up around the same creek system, which provided a means of distribution to Shiptonthorpe, Brough and other Romano-British settlements further afield. Fabric and form analysis of local wares when compared with pottery of known date showed that production began in the later 2nd century A.D., reaching a peak in the mid fourth.Clay was plentiful and managed woodland may have provided fuel for furnaced based industries. Settlement types showed little change from the late Iron Age, but followed developments paralleled elsewhere, with some degree of Romanisation. Marine flooding did not cause the decline of industry and settlement in the area as has been previously suggested. It is possible that these settlements formed the basis of the hamlets within the parish of Holme on Spalding Moor, although continuity has yet to be proved
Henry Harmon Spalding portrait
No full textA portrait of early Oregon settler Henry Harmon Spalding (1803–1874). This carte-de-visite photograph probable dates from the 1860s or early 1870s. Spalding was a missionary who came to the Oregon Territory in 1835, where he attempted to convert the Nez Perce and other tribes to Christianity. A handwritten note from Spalding to T. R. Cornelius appears on the back.[Transcription of handwritten note on back of photograph:] To Hon. T. R. Cornelius from his sincere friend, H. H. Spalding born in Steuben Co., N. y. 26 Nov. 1803.

Analysis of nanocrystalline ZnS thin films by XPS
No full textNanocrystalline ZnS thin films were synthesized by chemical vapor deposition (CVD) using
Zn(O-iPrXan)2 [O-iPrXan = S2COCH(CH3)2] as a single-source precursor compound. The coatings
were deposited on silica substrates in N2 atmosphere at temperatures between 200 and 450 °C and
subsequently characterized by glancing-incidence x-ray diffraction (GIXRD), secondary ion mass
spectrometry (SIMS), atomic force microscopy (AFM), UV-Vis absorption spectroscopy, x-ray
photoelectron (XPS), and x-ray excited auger electron (XE-AES) spectroscopies. This work is
dedicated to the XPS and XE-AES characterization of a representative zinc sulfide thin film.
Besides the wide scan spectrum, detailed spectra for the Zn 2p3/2, Zn 3p, Zn LMM, S 2p, O ls, and
C 1s regions and related data are presented and discussed. Both the S/Zn atomic ratio and the
evaluation of the Auger parameter point out to the formation of stoichiometric zinc sulfide.
Moreover, oxygen and carbon contamination were merely limited to the outermost sample layers

Synthesis, structure, spectroscopic and electrochemical study of the paramagnetic compound [2-(eta(7)-C7H7)-7,11-F-2-2,1-closo-MoTeB10H8]
No full textThe reaction of [NEt4][7-nido-TeB10H11] 1 with [Mo(CO)3(η7-C7H7)][BF4] 2 in dichloromethane yields the novel paramagnetic, B-fluorinated, “mixed-sandwich” compound [2-(η7-C7H7)-7,11-F2-2,1-closo-MoTeB10H8] 3 in 19% yield. An X-ray diffraction study of 3 establishes the closo twelve-vertex MoTeB10-cage structure with two B–F units at adjacent positions. The structure of 3 was solved in space group Pna21 with unit cell dimensions of a = 16.7598(18), b = 12.5500(11), c = 7.2607(18) Å, and Z = 4. The final R factor was 0.0291 for 1471 observed reflections. Principal interatomic distances are Mo–Te 2.7083(8), B–F 1.396(9) and 1.410(9) Å. In the MoTeB10 cage interatomic distances are in the ranges; Mo–B 2.363(8) to 2.481(9), Te–B 2.293(9) to 2.373(9) and B–B 1.720(13) to 1.943(12) Å. EPR spectra confirm the paramagnetic nature of 3 with the unpaired electron located in a mainly molybdenum-based molecular orbital. The cyclic voltammetric response of 3 exhibits a reversible one-electron reduction at E0′ = −0.39 V in dichloromethane solvent
Measurement of the top-quark mass in all-jets events in pp collisions at = 7 TeV
No full textThe mass of the top quark is measured using a sample of candidate events with at least six jets in the final state. The sample is selected from data collected with the CMS detector in pp collisions at = 7 TeV in 2011 and corresponds to an integrated luminosity of 3.54 . The mass is reconstructed for each event employing a kinematic fit of the jets to a hypothesis. The top-quark mass is measured to be 173.49 0.69(stat.) 1.21(syst.) GeV. A combination with previously published measurements in other decay modes by CMS yields a mass of 173.54 0.33(stat.) 0.96(syst.) GeV

Authority and discipline in Aberdeen, 1650-1700
No full textThis study is concerned with aspects of urban society in the
Scottish city of Aberdeen in the second half of the seventeenth
century. The principal aim is to examine the multi-faceted nature
and workings of civic government, of the interlocking hierarchies of
people and institutions which together formed an invisible web of
authority and discipline in the town. The burgh's three main
administrative and judicial bodies - the town council, the kirk
session, and the justice of the peace court - are examined in some
detail. Other matters discussed include the 1640's legacy of civil
war, plague, and severe economic dislocation; the impact of eight
years of Cromwellian occupation; the demographic and socio-economic
structures of the urban community; aspects of secular and
ecclesiastical politics; the continuing challenge to the established
kirk posed by Catholic recusancy, and the new challenge posed by the
advent of Quakerism in the town; patterns of office-holding and the
characteristics of the urban elite; and poor relief and social
control. The fundamental structures of urban society underwent no
sudden transformation in these years, but neither did they remain
static: far from obscuring the true dynamics of urban society, civic
institutions remained vital social, economic, and political forums
around which the forces of critical change coalesced, whether to be
adopted, adapted, repulsed; or neutralised, but always in such a way
as to shape the very structure and character of life in the town
