    Rhydderch — Broderick?

    No full text
    The paper focuses on the British family name Broderick that for many years was believed, but never adequately explained, to derive from the British personal name Rhydderch. However, in the recently published Oxford Dictionary of Family Surnames in Britain and Ireland (Oxford University Press, 2016) the editors have changed tack and suggested that the name may in fact be a nickname derived from Middle English meaning ‘broad-backed, broad shouldered’, found also in English place-names in the north of England to mean ‘broad ridge’, etc. The editors supply ample examples of both the family name and the place-name in all its spellings. Whilst the forms may be suitable in place-names the given forms in the context of the family name Broderick seem to be late, as the name itself looks to be of much earlier provenance. In looking at the name the author argues that the family name Broderick in fact derives from the British personal name Rhydderch and seeks to explain the relevant phonological developments.Статья посвящена британской фамилии Broderick, которая, как давно считается (хотя эта версия так и не получила всестороннего адекватного объяснения), является производным от британского личного имени Rhydderch. В недавно опубликованном «Оксфордском словаре фамилий Британии и Ирландии» (Oxford Dictionary of Family Surnames in Britain and Ireland, 2016) редакторы заняли иную позицию, интерпретируя эту фамилию как прозвище, восходящее к среднеанглийскому слову со значением ‘ широкую спину, широкие плечи’, которое также зафиксировано в топонимии севера Англии в значении ‘широкий мост’. Составители словаря дают множество вариантов соответствующих фамилии и топоосновы, приводя примеры их функционирования. И хотя для объяснения топонимных образований приводимые формы вполне пригодны, они не могут объяснить появление фамилии Broderick, которая, по мнению автора, возникла существенно раньше упоминаемых в словаре случаев. Автор отстаивает традиционную точку зрения, согласно которой фамилия Broderick восходит к личному имени Rhydderch, и пытается объяснить соответствующие фонетические переходы

    Proton-exchanged lithium niobate waveguides for photonic applications

    This talk shall provide an overview of the current activity on integrated LiNbO3 devices based on proton-exchange techniques at the ORC. We shall present the technology and the experimental results obtained so far on slab waveguides in 2D Nonlinear Photonic Crystals and on channel waveguides in Periodically Poled Lithium Niobate and discuss perspective applications for all-optical signal processing in ultra-fast fibre telecom systems

    Fiber laser systems for marine photonics

    No full text
    We review recent progress on optical fibre lasers and discuss applications for them in the field of marine photonics. In particular we examine high efficiency schemes (electrical to green light) based around short pulsed lasers and novel poled materials. Such light sources could find novel applications in underwater autonomous vehicles

    Nano-Imprinted Thin Films of Reactive, Azlactone-Containing Polymers: Combining Methods for the Topographic Patterning of Cell Substrates with Opportunities for Facile Post-Fabrication Chemical Functionalization

    No full text
    Approaches to the fabrication of surfaces that combine methods for the topographic patterning of soft materials with opportunities for facile, post-fabrication chemical functionalization could contribute significantly to advances in biotechnology and a broad range of other areas. Here, we report methods that can be used to introduce well defined nano- and microscale topographic features to thin films of reactive polymers containing azlactone functionality using nanoimprint lithography (NIL). We demonstrate that NIL can be used to imprint topographic patterns into thin films of poly(2-vinyl-4,4- dimethylazlactone) and a copolymer of methyl methacrylate and 2-vinyl- 4,4-dimethylazlactone using silicon masters having patterns of grooves and ridges ranging in width from 400 nm to 2μm, demonstrating the potential f this method to transfer patterns to films of these reactive polymers over a range of feature sizes and densities. We demonstrate further that the azlactone functionality of these polymers survives temperatures and pressures associated with NIL, and that topographically patterned films can be readily functionalized post-fabrication by treatment of surface-accessible azlactone functionality with small molecules and polymers containing primary amines. The results of experiments in which NIH-3T3 cells were seeded onto films imprinted with lined patterns having a pitch of 4 demonstrated that cells attach and proliferate on these azlactone-containing films and that they align in the direction of the imprinted pattern. Finally, we demonstrate that the treatment of these materials with amine-functionalized poly(ethylene glycol) (PEG) can be used to create regions of topographically patterned films that prevent cell adhesion. The results of this study suggest approaches to the functionalization of topographically patterned surfaces with a broad range of chemical functionality (e.g., peptides, proteins, carbohydrates, etc.) of biotechnological interest. The ability to manipulate and define both the physical topography and chemical functionality of these reactive materials could provide opportunities to investigate the combined effects of substrate topography and chemical functionality on cell behavior and may also be useful in a broad range of other applications

    We model fabricated silica photonic bandgap fibers and achieve good agreement between simulated and measured properties. We identify the size of the SEM bitmap image as the ultimate limit to the accurate calculation of surfaces modes within the bandgap
