Frantz H. Coe School, ca. 1910
No full textThe new Frantz H. Coe School building wasn't quite finished when classes started in the fall of 1906. Students spent their first year in portable buildings, and moved into the finished school building in the fall of 1907. Coe School was still the largest grade school in the Queen Anne neighborhood in the early 1960s.

Seawater redox variations during the deposition of the Kimmeridge Clay Formation, United Kingdom (Upper Jurassic): evidence from molybdenum isotopes and trace metal ratios
No full textThe Kimmeridge Clay Formation (KCF) and its equivalents worldwide represent one of the most prolonged periods of organic carbon accumulation of the Mesozoic. In this study, we use the molybdenum (Mo) stable isotope system in conjunction with a range of trace metal paleoredox proxies to assess how seawater redox varied both locally and globally during the deposition of the KCF. Facies with lower organic carbon contents (TOC 1–7 wt %) were deposited under mildly reducing (suboxic) conditions, while organic-rich facies (TOC >7 wt %) accumulated under more strongly reducing (anoxic or euxinic) local conditions. Trace metal abundances are closely linked to TOC content, suggesting that the intensity of reducing conditions varied repeatedly during the deposition of the KCF and may have been related to orbitally controlled climate changes. Long-term variations in ?98/95Mo are associated with the formation of organic-rich intervals and are related to third-order fluctuations in relative sea level. Differences in the mean ?98/95Mo composition of the organic-rich intervals suggest that the global distribution of reducing conditions was more extensive during the deposition of the Pectinatites wheatleyensis and lower Pectinatites hudlestoni zones than during the deposition of the upper Pectinatites hudlestoni and Pectinatites pectinatus zones. The global extent of reducing conditions during the Kimmerigidan was greater than today but was less widespread than during the Toarcian (Early Jurassic) oceanic anoxic event. This study also demonstrates that the Mo isotope system in Jurassic seawater responded to changes in redox conditions in a manner consistent with its behavior in present-day sedimentary environment
"Rhodium catalysed borylation reactions via direct and indirect c-h activation"
No full textThis thesis describes both direct and indirect C-H activation borylation processes, catalysed by several Rh-based catalyst precursors. Chapter One presents an overview of the processes investigated, namely diboration, dehydrogenative borylation, and direct C-H activation of hydrocarbon substrates, which give borylated species that are of interest to synthetic chemists. The uses of such borylated species are also highlighted. Chapter Two highlights the synthetic procedure for the synthesis of the catalyst precursor [Rh(acac)(C0E)(_2)], which can be used to prepare bis-phosphine catalyst precursors of the form [Rh(acacXP(_2))]- Although a procedure appears in the literature, it is not well cited. Also, this new procedure replaces [Tl(acac)] with [Na(acac)] and hence avoids the use of thallium salts. Chapter Three investigates the reaction of two vinyl(boronate) esters (VBEs) with Bzcat], and a wide array of catalyst precursors, which yield, among other species, the tris(boronate) esters ArCH(_2)C(Bcat)(_3) and ArCH(Bcat)CH(Bcat)(_3); the former results from the addition of both borons of the B(_2) unit to the same carbon atom, and are of interest due to their wide synthetic versatility. Chapter Four investigates the dehydrogenative borylation of alkenes using both HBpin and B2pin2, and several catalyst precursors. Most significantly, this route allows the synthesis of 1,1-disubstituted vinyl(boronate) esters that cannot be made by alkyne hydroboration. Chapter Five investigates the direct C-H activation of benzylic and aromatic hydrogens using the catalyst precursor [Rh(Cl)(N(_2))(P(^i)Pr(_3))(_2)]. This allows the functionalisation of hydrocarbon substrates, which are ubiquitous. Chapter Six investigates the stability of B-chlorocatecholborane to phosphines with the view to a boron analogue of the Heck reaction. In such a reaction, phosphmes would likely be employed on the catalyst. An understanding of the stability of the boron reagent under typical reaction conditions is needed, therefore, in order to prevent degradation of B-chlorocatecholborane, a process that is known for catecholborane

XMM-Newton observation of the highly magnetised accreting pulsar Swift J045106.8-694803: evidence of a hot thermal excess
No full textSeveral persistent, low luminosity (LX ~ 1034 erg s-1), long spin period (P > 100 s) High Mass X-ray Binaries have been reported with blackbody components with temperatures > 1 keV. These hot thermal excesses have correspondingly small emitting regions (< 1 km2) and are attributed to the neutron star polar caps. We present a recent XMM-Newton target of opportunity observation of the newest member of this class, Swift J045106.8-694803. The period was determined to be 168.5 ± 0.2 s as of 17 July 2012 (MJD = 56125.0). At LX ~ 1036 erg s-1, Swift J045106.8-694803 is the brightest member of this new class, as well as the one with the shortest period. The spectral analysis reveals for the first time the presence of a blackbody with temperature kTBB = 1.8 +0.2-0.3 keV and radius RBB = 0.5 ± 0.2 km. The pulsed fraction decreases with increasing energy and the ratio between the hard (> 2 keV) and soft (< 2 keV) light curves is anticorrelated with the pulse profile. Simulations of the spectrum suggest that this is caused by the pulsations of the blackbody being ~ π out of phase with those of the power law component. Using a simple model for emission from hot spots on the neutron star surface, we fit the pulse profile of the blackbody component to obtain an indication of the geometry of the system

Coe Family Papers, 1836-1943
No full textThe Coe family papers consist primarily of business records of the brothers Eben S. Coe and Thomas Upham Coe, with a few papers of Thomas\u27s wife, Sada L. Coe. The materials reflect the involvement of the Coes in land acquisition and management and the lumber industry in the northern part of Maine, as well as Eben Coe\u27s partnership in the S.R. Bearce and R.C. Pingree companies in Lewiston, Maine. Much information is also included about the administration of the very sizeable estate left by Thomas Upham Coe at his death in 1920.https://digitalcommons.library.umaine.edu/findingaids/1202/thumbnail.jp
