R.M. Simmons presentation, Rena Smart book review
No full textR.M. Simmons of the Gospel Music Workshop of America gives a presentation on the African influence in the African American religious experience. He explains how African slaves brought to America their concept of music (utilitarian concept of music). Simmons further discusses the fusion between the utilitarian concept and the Western concept of religion resulting in spirituals. He also describes hymn categories in early forms of formal African American worship experiences. Simmons takes questions from the audience among which is Dr. Riggins Earl Jr. Video concludes with a book review on Christian Theology and Ethics by Rena Smart.The Atlanta University Center Robert W. Woodruff Library acknowledges the generous support of the National Endowment for Humanities - Humanities Collections and Reference Resources Implementation Project Grant in supporting the processing and digitization of a number of its major archival collections as part of the project: Spreading the Word: Expanding Access to African American Religious Archival Collections at the Atlanta University Center Robert W.

Localised and delocalised plasmons in metallic nano-voids
No full textNanostructured metal films comprised of periodically arranged spherical voids are grown by electrochemical deposition through a self-assembled template. Detailed measurements of the angle- and orientation-dependent reflectivity for different sample geometries reveal the spectral dispersion of several different types of surface plasmon modes. The dependence of the energies of both delocalized Bragg and localized Mie plasmons on the void goemetry is presented, along with theoretical models to explain some of these experimental findings. Strong interactions between the different plasmon modes as well as other mixing processes are identified. Understanding such plasmonic crystals allows for the engineering of devices tailored for a wide range of sensing application
The fabrication of plasmonic Au nano-void trench arrays by guided self-assembly
No full textMetallic nanoscale voids can support both localized and propagating plasmons and form plasmonic crystals. However, constructing 1D arrays is crucial for producing plasmonic circuits. In this paper we report the first experimental evidence of plasmons in templated linear arrays of self-assembled structures. Single and multilayer arrays of gold voids have been fabricated through self-assembly of sub-micron polystyrene spheres in V-shaped trenches in silicon, followed by selective area electrodeposition. Angle-dependent dispersion characteristics reveal the existence of localized plasmon
Micropropagation of Brassica oleracea (Cole crops)
No full textBrassica oleracea, (family Brassicaceae), also referred to as cole crops (Nieuwhof 1969; Yamaguchi 1983; Nonnecke 1989), is an economically important vegetable species composed mostly of biennially herbaceous plants, grown as annuals or biennials, depending on the part harvested. Practically every part of the plant can be used, including leaves (cabbage, kale), axillary buds (Brussels sprouts), stems (kohlrabi), flower buds (broccoli), and floral primordia (cauliflower). It is a highly polymorphic species, and has over 40 members (Bailey 1976). Table 1 summarizes eight of the most important varieties commonly grown throughout the world
William Cole Arms Collection
No full textWilliam Cole started acquiring antique firearms in the early 20th century. Cole made his earliest donations to the Museum in 1918 and donated the bulk of his collection to the Museum in September 1943. There are over 250 objects in the collection, which has a particular focus on English, Scottish and Irish gunmakers from the late 18th and 19th centuries.Private collecting of antique firearms in Australia was still in its infancy when William Cole (1864-1952) started acquiring items in the early 20th century. Cole had an eye for quality and had developed an appreciation for the work of the English gunmakers at the end of the 18th century and early 19th century. Even so, a particularly high quality Colt 1849 Pocket revolver in the collection highlights his unrestricted tastes and what appears to have been the overriding criterion of condition and quality. In 1918 Cole made his earliest donations to the Museum, an English sporting rifle by R.M. Reiley and related ammunition. William donated the bulk of his collection to the Museum in September 1943, and it is listed in the archival correspondence surrounding the donation in the following terms: 'It comprises 121 flint and percussion pistols and revolvers, 18 cases of pistols (pairs) with accessories complete, 6 blunderbusses, 29 flint and percussion long arms, 31 powder flasks and belts, 2 burglar alarms, 1 trap gun, and 1 miscellaneous assortment of gun tools, cartridges, etc. The firearms are in excellent condition and many of them are related to that period when London gun-makers developed the tradition of fine craftsmanship which, to this day, is unequalled anywhere in the world. The gift is an outstanding one in view of the fact that old firearms are becoming scarcer, prices higher and finds few and far between.' The collection was later described as 'the largest single collection of antique firearms in Australia' (Penrose 1949). The collection includes pistols, rifles and shotguns made by leading English, Scottish and Irish gunmakers in the late 18th and 19th centuries, including Durs Egg, John Manton, Robert Wogdon and Samuel Nock; as well as a number of contemporary Birmingham forgeries of famous makers. The collection also includes a cased pair of percussion pistols by London gunsmith T. J. Mortimer in the 1830s, which are significant for having been owned by Thomas Alexander Browne, who as Rolf Boldrewood wrote the Australian classic Robbery Under Arms (1888). William Cole died on 17 March 1952, having left provision for additional items of his collection to be donated to the Museum after his death. This wish was fulfilled in the following years by his only remaining daughter, Doris. Many of these items seem to have been Cole's own sporting rifles or particularly treasured items, such as the Martini actioned sporting rifle presented by Cole to his son Cleveland. Doris also donated a portrait photograph of her father holding one of his pair of pistols by the famous English maker Durs Egg.

Velocity-Gradient Probability Distribution Functions in a Lagrangian Model of Turbulence
No full textThe Recent Fluid Deformation Closure (RFDC) model of lagrangian turbulence is recast in path-integral language within the framework of the Martin-Siggia-Rose functional formalism. In order to derive analytical expressions for the velocity-gradient probability distribution functions (vgPDFs), we carry out noise renormalization in the low-frequency regime and find approximate extrema for the Martin-Siggia-Rose effective action. We verify, with the help of Monte Carlo simulations, that the vgPDFs so obtained yield a close description of the single-point statistical features implied by the original RFDC stochastic differential equations
Easily coupled whispering gallery plasmons in dielectric nanospheres embedded in gold films
No full textA new self-aligned robust method for coupling to whispering gallery modes (WGMs) of submicron microspheres utilizes their periodic arrangement without relying on nanopositioned external coupling devices. The microspheres are embedded in a nanostructured gold surface supporting delocalized plasmonic crystal modes that mediate the coupling, and can be tuned by the geometry. Detailed measurements of the angle- and orientation-dependent reflectivity reveal localized plasmonic WGMs whose energies scale with sphere diameter and agree closely with Mie calculations. Coupling between these plasmonic WGMs leads to mode splitting and the formation of plasmonic minibands of a controllable bandwidth

Adult socioeconomic, educational, social, and psychological outcomes of childhood obesity: a national birth cohort study
No full textObjectives: To assess adult socioeconomic, educational, social,
and psychological outcomes of childhood obesity by using
nationally representative data.
Design: 1970 British birth cohort.
Participants: 16 567 babies born in Great Britain 5-11 April
1970 and followed up at 5, 10, and 29-30 years.
Main outcome measures: Obesity at age 10 and 30 years. Self
reported socioeconomic, educational, psychological, and social
outcomes at 30 years. Odds ratios were calculated for the risk of
each adult outcome associated with obesity in childhood only,
obesity in adulthood only, and persistent child and adult
obesity, compared with those obese at neither period.
Results: Of the 8490 participants with data on body mass index
at 10 and 30 years, 4.3% were obese at 10 years and 16.3% at 30
years. Obesity in childhood only was not associated with adult
social class, income, years of schooling, educational attainment,
relationships, or psychological morbidity in either sex after
adjustment for confounding factors. Persistent obesity was not
associated with any adverse adult outcomes in men, though it
was associated among women with a higher risk of never
having been gainfully employed (odds ratio 1.9, 95% confidence
interval 1.1 to 3.3) and not having a current partner (2.0, 1.3 to
3.3).
Conclusions: Obesity limited to childhood has little impact on
adult outcomes. Persistent obesity in women is associated with
poorer employment and relationship outcomes. Efforts to
reduce the socioeconomic and psychosocial burden of obesity
in adult life should focus on prevention of the persistence of
obesity from childhood into adulthood
