The stable isotopic composition of historical black powder applicable to a Japanese Tanegashima matchlock

The objective of the present study is to employ stable isotope ratio measurements (δ¹⁵N, δ³⁴S and δ¹³C) of the nitrogen, sulphur and carbon in black powder (a mixture of saltpetre, native sulphur and charcoal) as a means of source identification. A sum total of 20 samples of historical black powder applicable to matchlocks were collected from six locations throughout Japan. This classic type of hand gun prevailed up to the introduction of the modern rifles, with quicker loading and higher efficiency, in the mid‐to‐late 19th century. δ¹³C_{charcoal carbon} values showed the predominant use of C₃ plants as a source material. Except for a few unusual samples with a probable exotic origin, δ¹⁵N_{saltpetre nitrogen} values were largely consistent with those of domestic products using classical biotechnology. The isotopic analysis for native sulphur (δ³⁴S_{native sulphur}) indicates a complicated marketing route.

The various applications and the resulting medical and technical requirements are discussed. Different gold alloy types are presented and described with reference to their composition, mechanical and physical properties, corrosion resistance and biocompatibility. Techniques new to dentistry such as powder metallurgy, electroforming and the use of pure gold direct filling are also discussed.     

President Obama,the Bible,and Political Rhetoric

Abstract

How has President Obama made use of the Bible in his political rhetoric, especially as it relates to public policy debates? This article addresses Obama's religious origins, his work as a community organizer in Chicago, his coming to Christian faith under the leadership of Rev. Jeremiah Wright, and the development of his understanding regarding the relationship between faith and politics. In particular President Obama has emphasized the notion that we are all our brothers' and sisters' keepers. He also stresses the present generation of black Americans as "the Joshua Generation." The article considers President Obama's hermeneutics, as well as the important context of the black church for his own use of Scripture. The lenses of Abraham Lincoln, Martin Luther King, Jr. and Reinhold Niebuhr are also addressed as they relate to Obama's use of Scripture in political rhetoric.     

Madonna and Child of Soweto: Black Life Beyond Apartheid and Democracy

ABSTRACT

South African artist Laurence Vincent Scully’s 1973 painting, Madonna and Child of Soweto, offers an analytical tool for understanding the capacity of public religion to advance black life. The author argues that this image censures apartheid violence against black persons and reimagines a just sociality by displaying sacred, black motherhood and infancy in the figures Mary and Jesus. Their temporality and corporeality, when analyzed with a queer womanist method, gestate sacred public religion that exceeds both the apartheid governance of the past and also the secular, post-apartheid democracy of today.     

'Who do you talk to,when a body's in trouble?: M. Nourbese Philip's (un)silencing of black bodies in the diaspora

This paper examines Marlene Nourbese Philip's 'Dis Place—The Space Between' to argue that black women's bodies are troubled by Philip in order to reconceptualize and reinvent location, corporeality, subjectivities, and dominant historical narratives. In situating blackness and black femininity within a displaced, or 'anywhere' framework, Philip scrutinizes and redraws the places of black women's bodies in the New World so that we might reconsider the geographical and historical importance of blackness. This paper therefore analyses how Philip takes up the chaotic in between-ness of black womanhood in order to embrace discourses and spaces of 'elsewhere' and possibility, while also acknowledging sites of racism, sexism, memory and struggle.     

A multi-analytical approach to characterize an Early Bronze Age cosmetic material from Müslümantepe,Southeastern Anatolia

The present paper reports the chemical and mineralogical composition of a black pigment material contained in a Syrian Bottle-shaped vessel excavated on an Early Bronze Age grave in Müslümantepe, a site located at the right bank of the Tigris River in Southeastern Anatolia. A combination of different analytical tools like state-of-the-art non-destructive μ-XRD², μ-XRF and μ-Raman spectroscopy compared to classical powder XRD was used to characterize the content of the bottle. The results attest the presence of a manganese mineral (pyrolusite) most probably used for cosmetic purposes. This is the first evidence, which is scientifically tested, of the earliest use of cosmetics in the Upper Tigris of Southeastern Anatolia during the Early Bronze Age period, c. 2700–2550 bc.     

Crusading in Africa: Religion,Race, and Post-9/11 Intervention in Antoine Fuqua’s Tears of the Sun (2003)

Abstract

African American director Antoine Fuqua’s Tears of the Sun, a 2003 war ?lm made with US Navy cooperation, imagines the intervention of Navy SEALs in an ethnic cleansing being conducted against Christians by Nigerian Muslims. It is at once an exercise in black diasporic consciousness and an expression of American exceptionalism. The director aimed to raise awareness of contemporary African crises, but the picture is also the closest Hollywood combat cinema came in the immediate post-9/11 years to addressing and endorsing the polarizing discourse and militarism of the Bush administration. The ?lm’s use of reductive religious imagery, its weak box of?ce return, and its generally hostile reception overseas expose its failure as a tool of diplomacy and reveal the waning ability of triumphalist Hollywood cinema to de?ne or explain the ‘War on Terror’.     

New Technologies of Embroidered Robe Production and Changing Gender Roles in Zaria,Nigeria, 1950–2005

Abstract

The old walled section of the Northern Nigerian town of Zaria known as Zaria City is renowned for the production of elaborately hand-embroidered robes, worn by men throughout Nigeria and West Africa. These garments are of some antiquity, yet they continue to be produced. None the less, there have been several changes in their production, including the introduction and expanded use of embroidery machines and new materials by men, new marketing practices, and women's hand-embroidery of robes. These changes are closely linked with political, economic, and socio-cultural factors, reflecting technological innovation, changes in gender-associated work, and the impact of federal import regulations in Zaria.

An aid to more expeditious and accurate recording of archaeological features requiring neither a power source nor specialized training to operate has been developed in Germany and is currently in use on excavations in several European countries. This article presents the specifications of the Kartomat field-drawing machine, provides examples of its application, and offers suggestions for its production and use in the United States.     

Cinchona and Quinine: A Remarkable Anniversary

Abstract

The use of the bark of the 'fever tree', cinchona, to cure intermittent fevers was first described in print by an Augustian monk in 1638, just over 350 years ago. The discovery and the first records are here chronicled. As such fevers were widespread, demand for the bark increased greatly, and attempts were made to establish cinchona tree plantations in tropical zones, most of them unsuccessfully. Only Dutch commercial production in what is now Indonesia was profitable. Chemical synthesis of antimalarial drugs reduced natural production of quinine for a time, but as drug resistance among the parasites that cause the malaria has increased, culvitation of the natural source has again become important.     

Brain–computer interfaces: a review

Abstract

The potential of remotely sensed data to analyze resources on the surface of the Earth was transformed by the launch of the first Landsat spacecraft in 1972. Here the principal features of present and future Earth resource satellites and sensors are discussed, and four case histories provided where such data are proving of high practical value. The examples are in the fields of geological exploration for oil and gas, commercial forecasting of crop production, multi-resource surveys of developing countries, and the production of regional photomaps. None of these applications could be performed at reasonable cost and within a reasonable time without the use of satellite data.     

Railway Architecture: The Great Northern Railway (Ireland) at Dundalk

ABSTRACT

This article is adapted from the dissertation ‘Railway Architecture: The Great Northern Railway (Ireland) at Dundalk’, completed by Siobhan Osgood for the MPhil in Art History: Art + Ireland, where it was awarded a distinction. The study provides an historical analysis in the context of architectural development and broader railway culture in Ireland to provide an interpretation and understanding of the use of polychromatic yellow, red and black brickwork to create a visual identity for railway architecture. The use of accented colours to pick out key features is repeated across a series of buildings, thus creating a distinctive style of ‘brick-branding’. These are most prominent in the town of Dundalk, where the GNRI had its central engineering works at the halfway point on the Dublin to Belfast mainline and at the point where the Irish North line extended west and north. The buildings were each intricately designed by the GNRI's first chief engineer, William Hemingway Mills, a second-generation railway engineer who merged the roles of architect and engineer using an amalgamation of architectural designs from his earlier career in Derby, Scotland, Mexico and Spain. Mills thus created his own ‘Millsian’ style of industrial architectural design.     

James Cone’s Legacy for White Christians

ABSTRACT

This article explores James Cone’s lesson and legacy for white Christians. Specifically, it analyzes Cone’s claim that whites can “become black.” Cone insists that a process of conversion to blackness “means that white people are prepared to deny themselves (whiteness), take up the cross (blackness), and follow Christ (black ghetto).” In this essay, I will draw upon Cone’s writings and original interview material to construct an outline of these three steps of becoming black. Making sense of what it means to convert to blackness begins with first analyzing his specific challenge to white theology, then his concepts of blackness and the Black Christ, and finally, the praxis of these three steps – that is, what does it look like, practically, to follow the black Christ as a white person.     

The Antinomies of Black Identity Formation in West Africa, 1820–1848

Abstract

During the mid-nineteenth century, a group of United States-born property-holding free blacks struggled to establish themselves and fashion a new polity on the coast of West Africa. In doing so, these Liberians embraced a pair of simultaneously complementary and opposing aspirations: first, the insertion, entrenchment and expansion of a successful black commercial bourgeoisie into the global Atlantic economy of the nineteenth century, an aspiration tied to and dependent upon the accumulation of capital and the creation of a state which would operate in the interest of this group and no other. Secondly, they aspired to the creation and institutionalisation of a separate and distinct black nationality - a black identity - that covered the entire spectrum of people of African descent, that held out the prospect of solidarity for all black people in republican equality and citizenship, and that subsumed all other classes and categories of black people under the tent of the imagined black nation. In this way they contributed to the uneven, reciprocal and trans-Atlantic work of black identity formation during the middle of the nineteenth century.     

A still worm from excavations at Carrick Castle,Argyll

Abstract

During 1993 excavations at Carrick Castle, Argyll, a rare item of distilling equipment was unearthed. Possibly dating to the 17th century, the copper alloy condenser or ‘worm’ is unique in design. Pollen analysis of an associated soil sample supports a use in the production of grain spirits. The technology of manufacture and historical context of the worm are examined in depth.     

Review articles/Besprekingsartikels

Abstract

Swiss missionary Henri Alexandre Junod has been widely recognised for his extensive entomological, botanical, linguistic and anthropological contributions regarding southern Africa. However, shortly after publishing his most acclaimed work, The Life of a South African Tribe, Junod wrote a little-studied novel, Zidji: étude de m?urs sud-africaines, in which he endeavoured to give a detailed portrayal of South African Society. Interestingly, he chose fiction as the best vehicle for conveying what he saw as the 'truth' of the situation. As the only novel written by Junod this is a unique piece of writing in relation to his other work and its study shows that it is essential to an understanding of Junod. In Zidji he attempts to give a complete picture of South African society at the beginning of the twentieth century by recounting a black convert's experiences of what Junod considered to be the three main influences acting upon black society of the time, that is, tribal life (paganism), the mission station (Christianity) and white society (civilisation). By considering his depiction of South Africa, in particular his presentation of 'civilisation', further light is shed on his sentiments and perspective of the missionary encounter, social change and race relations in South Africa.     

Political Theology as Liberative Theology

ABSTRACT

Challenging the widespread assumption that “political theology” as a discipline began with Carl Schmitt in the 20th century, this essay explores the biblical theme of God’s preferential option for the poor and oppressed first articulated as a modern political theology by Latin American theologians, but organically and independently manifest in US black liberation theology, and First World feminist theologies. At the heart of this movement is a commitment to speak truth to power at the risk of personal loss and even martyrdom.     

“But Do the Lord Care?”

Abstract

The slain rapper Tupac Shakur contributes indispensably to two contemporary theologies centered around the crucified people, the theological aesthetics of liberation presented by Roberto Goizueta and the theology of the lynching tree articulated by James Cone. Placing the pioneering work of Goizueta and Cone in conversation with existing scholarship on the theological importance of Shakur’s music, I argue that Tupac crafts a theological aesthetics of liberation aimed at illuminating the injustice and Christological implications of the hypersegregated ghetto and the black mass prison     

The Cooper in Liverpool

Abstract

This report assesses the efficiency in timing and layout of the mass-production system at the Portsmouth Dockyard block mill in the early 1800s. It is based on study of the extant buildings and machines as well as pictorial and written evidence from the past. Early output figures for some of the block-making machines reveal 8 to 17 per cent discrepancies from perfect coordination in timing. This difficulty was apparently offset by use of duplicate machines and by short-term stacking up of semi-finished parts between machine processes. An old line shafting diagram implies that the three sets of machines for making pulley-block shells of different sizes were arranged on one shop floor in a hollow rectangle, each set in its own production sequence. Although not ideal, the machinery's coordination and layout showed a greater rationality of design for efficient production 'flow' than has heretofore been documented for it.
