Almost half of the 4822 described beeflies in the world belong to the subfamily Anthracinae, with most of the diversity found in three cosmopolitan tribes: Villini, Anthracini, and Exoprosopini. The Australian Exoprosopini previously contained three genera, Ligyra Newman, Pseudopenthes Roberts and Exoprosopa Macquart. Pseudopenthes is an Australian endemic, with two species including Ps. hesperis, sp. nov. from Western Australia. Two new species of the exoprosopine Atrichochira Hesse, Atr. commoni, sp. nov. and Atr. paramonovi, sp. nov., are also described from Australia, extending the generic distribution from Africa. Cladistic analysis clarified the phylogenetic relationships between the recognised groups of the Exoprosopini and determined generic limits on a world scale. Inclusion of 18 Australian exoprosopines placed the Australian species in the context of the world fauna. The Exoprosopini contains six large groups. The basal group I contains species previously included in Exoprosopa to which the name Defilippia Lioy is applied. Group II contains Heteralonia Rondani, Atrichochira, Micomitra Bowden, Pseudopenthes, and Diatropomma Bowden. Colossoptera Hull is newly synonymised with Heteralonia. Group III is a paraphyletic assemblage of Pterobates Bezzi and Exoprosopa including the Australian Ex. sylvana ( Fabricius). Ligyra is paraphyletic, forming two well-separated clades. The African clade is described as Euligyra Lambkin, gen. nov., which, together with Litorhina Bezzi and Hyperalonia Rondani, form group IV. The Australian group V is true Ligyra. The remaining monophyletic lineage of exoprosopines, group VI, the Balaana-group of genera, shows evidence of an evolutionary radiation of beeflies in semi-arid Australia. Phylogenetic analysis of all 42 species of the Balaana-group of genera formed a basis for delimiting genera. Seven new genera are described by Lambkin & Yeates: Balaana, Kapua, Larrpana, Munjua, Muwarna, Palirika and Wurda. Four non-Australian species belong to Balaana. Thirty two new Australian species are described: Bal. abscondita, Bal. bicuspis, Bal. centrosa, Bal. gigantea, Bal. kingcascadensis, K. corusca, K. irwini, K. westralica, Lar. collessi, Lar. zwicki, Mun. erugata, Mun. lepidokingi, Mun. paralutea, Mun. trigona, Muw. vitreilinearis, Pa. anaxios, Pa. basilikos, Pa. blackdownensis, Pa. bouchardi, Pa. cyanea, Pa. danielsi, Pa. decora, Pa. viridula, Pa. whyalla, W. emu, W. impatientis, W. montebelloensis, W. norrisi, W. patrellia, W. skevingtoni, W. windorah, and W. wyperfeldensis. The following new combinations are proposed: from Colossoptera: Heteralonia latipennis (Brunetti); from Exoprosopa: Bal. grandis (Pallas), Bal. efflatounbeyi (Paramonov), Bal. latelimbata ( Bigot), Bal. obliquebifasciata ( Macquart), Bal. tamerlan (Portschinsky), Bal. onusta ( Walker), Def. busiris (Jaennicke), Def. efflatouni ( Bezzi), Def. eritreae (Greathead), Def. gentilis ( Bezzi), Def. luteicosta ( Bezzi), Def. minos (Meigen), Def. nigrifimbriata ( Hesse), Def. rubescens ( Bezzi), K. adelaidica ( Macquart), Lar. dimidiatipennis ( Bowden), Muw. stellifera ( Walker), and Pa. marginicollis ( Gray); from Ligyra: Eu. enderleini ( Paramonov), Eu. mars ( Bezzi), Eu. monacha (Klug), Eu. paris ( Bezzi), Eu. sisyphus ( Fabricius), and Eu. venus (Karsch).

The muscle isoform. of clathrin heavy chain, CHC22, has 85% sequence identity to the ubiquitously expressed CHC17, yet its expression pattern and function appear to be distinct from those of well-characterized clathrin-coated vesicles. In mature muscle CHC22 is preferentially concentrated at neuromuscular and myotendinous junctions, suggesting a role at sarcolemmal contacts with extracellular matrix. During myoblast differentiation, CHC22 expression is increased, initially localized with desmin and nestin and then preferentially segregated to the poles of fused myoblasts. CHC22 expression is also increased in regenerating muscle fibers with the same time course as embryonic myosin, indicating a role in muscle repair. CHC22 binds to sorting nexin 5 through a coiled-coil domain present in both partners, which is absent in CHC17 and coincides with the region on CHC17 that binds the regulatory light-chain subunit. These differential binding data suggest a mechanism for the distinct functions of CHC22 relative to CHC17 in membrane traffic during muscle development, repair, and at neuromuscular and myotendinous junctions.

The gain-switched, single frequency operation of an external cavity grating-coupled surface emitting laser with a wavelength tuning range of 100 nm was presented. The light in the grating section was coupled out of the laser at a specific angle to the surface of the device. Analysis showed that within the driving current range, lasing in the device only occurred when the external cavity was properly aligned.

In the years following the fall of Slobodan Milo evic, Serbian social, cultural and political responses to the wars of the 1990s have fallen under intense international scrutiny. But is this scrutiny justfied, and how can these responses be better understood? Jelena Obradovic engages with ideas about post-conflict societies, memory, cultural trauma, and national myths of victimhood and justified war to shed light upon Serbian denial and justification of war crimes - for example, Serbia's reluctant cooperation with the International Criminal Tribunal for the former Yugoslavia (ICTY). Rather than treating denial as a failure to come to terms with the past or as resurgent nationalism, Obradovic argues that the justification of atrocities are often the result of a societal need to understand and incorporate violent events within culturally acceptable boundaries.

Widely tunable gain switching of a grating-coupled surface-emitting laser (GCSEL) has been demonstrated in a simple external cavity configuration for the first time. Pulse duration in range of 40-100ps and wavelength tuning over 100nm have been achieved. High power, tail-free optical pulses have been observed at 980nm.

Triggered biodegradable composites made entirely from renewable resources are urgently sought after to improve material recyclability or be able to divert materials from waste streams. Many biobased polymers and natural fibers usually display poor interfacial adhesion when combined in a composite material. Here we propose a way to modify the surfaces of natural fibers by utilizing bacteria (Acetobacter xylinum) to deposit nanosized bacterial cellulose around natural fibers, which enhances their adhesion to renewable polymers. This paper describes the process of modifying large quantities of natural fibers with bacterial cellulose through their use as substrates for bacteria during fermentation. The modified fibers were characterized by scanning electron microscopy, single fiber tensile tests, X-ray photoelectron spectroscopy, and inverse gas chromatography to determine their surface and mechanical properties. The practical adhesion between the modified fibers and the renewable polymers cellulose acetate butyrate and poly(L-lactic acid) was quantified using the single fiber pullout test. © 2008 American Chemical Society.

La historia del arte está inevitablemente ligada al desarrollo tecnológico. La escultura es una disciplina artística que ha estado presente en toda la historia de la humanidad, desde las venus paleolíticas hechas a mano, hasta esculturas contemporáneas realizadas con tecnologías digitales. Estas últimas son el tema principal de esta tesis. El siglo XX ha sido testigo de la aparición y el desarrollo de la informática. El desarrollo de esta tecnología se debe, fundamentalmente, a su potencial sobre todo en el campo de la ingeniería, pero es un error pensar que el desarrollo de la informática se debe sólo a ingenieros y científi cos. Los artistas han participado en todo el desarrollo de los gráfi cos por ordenador, jugando un papel muy importante en el nacimiento y la evolución de los sistemas de modelado en tres dimensiones. Desde que Charles Babagge conceptualizara la computadora a fi nales del siglo XIX, la informática ha evolucionado a un ritmo vertiginoso...

Sex sells. A lot. But who exactly is on the market?

What kinds of bodies are calibrated for traffic and consumption, and how exactly do they get there? When it comes to “sex” trafficking—which comprises a minority percentage of human trafficking, yet dominates the moral imagination as an “especially heinous” crime—the rise in predominantly white, evangelical Christian American interest in the trafficked subject galvanizes an ethical outrage that rarely observes critiques of race, ethnicity, sexuality or class as conditions of possibility. Though a nuanced mandate to fight trafficking is all but cemented in the contemporary American political and moral conscience, Virgin Territory accounts for the ways Christian ideas of purity annex both gender and sexuality inside the legacies of racialized colonial encounter, and foreground the market expansion of the global sex trade as it exists today.

In Part I, I argue that the narratives of virginity tied to Mary’s body simultaneously foregrounded the gendered, sexed Other as sparked disdain for the religious Other, for the Jewish body and for Mary’s Jewish identity. Through this analysis I explore the connections of racial identity to the Christian theological elision of Jewish election. I demonstrate how the questions of sexual ethics materialized at the site of the Virgin Mary, and align the moral attachments of sex and purity in the production of whiteness. These machinations, tied to the emerging European identity of empire, irrupt horrifically into the narrative ontology of dark flesh in Africa, Asia, and the Americas.

In Part II, I highlight the function of these narratives inside of the moments of colonial encounter, demonstrating how the logics of purity and virginity were directly applied to manage dark female flesh. I map the visual iconography of the Black Madonna first through a Dutch painting entitled The Rape of the Negress. I read this image through the social theological imagination instantiating the idea of the reprobate body and white imperial gaze. This analysis foregrounds a theological reading of Sarah Baartman, the “Hottentot Venus,” as the center of a complex sex trafficking investigation, outlining the genealogy of race, as well as the ideologies of the racial, ethnic and national Other, as mitigating factors in the conditions of possibility of a global sex trade. By restoring these narratives and their theological undertones, I reiterate the ways Christian thought is imbricated in the global sex trade, and propose theological strategies for rethinking humanitarian responses to sex trafficking.
