Title: Mineralogy and Sourcing of a Stone Bead Industry Found in Communal Cemeteries Associated with Eastern Africa's First Pastoralists, ca. 5000
This article describes the mineralogy and sources for a spectacular stone bead industry associated with the first pastoralists in eastern Africa ca. 5000–4000 CAL B.P. Around Lake Turkana, northwest Kenya, early pastoralists constructed at least seven mortuary monuments with platforms, pillars, cairns, and stone circles. Three sites—Lothagam North, Manemanya, and Jarigole—have yielded assemblages of stone and ostrich eggshell beads that adorned interred individuals. Mineralogical identification of the stone beads reveals patterns of material selection, including notable differences among the pillar sites. Geological sourcing indicates use of many local raw materials and two (amazonite and fluorite) whose known sources lie>200 km away. The data suggest that bead-making represented a significant investment by early pastoralists in personal ornamentation. New sociopolitical factors emerged, such as access to grazing grounds and water, and definitions of self and society manifested in novel mortuary traditions as people coped with a drying, cooling climate.  more » « less

  1. Southern Africa presents the best-documented Middle and Later Stone Age (MSA and LSA) records in Africa, and yet signi cant uncertainties still exist concerning the sequence and timing of behavioral and occupational changes in the region. A recent surge in research has provided a suite of new results that indicate more intricate and complex pa erns than those previously considered. This paper describes recent excavations at the archaeological site of Varsche Rivier (VR) 003 located in the poorly-researched southern Namaqualand (Knersvlakte) region of South Africa (Western Cape Province). Two seasons of excavations have revealed a long sequence of MSA and LSA cultural materials, including lithics, fauna, ostrich eggshell, marine mollusks, beads, and pigments; bedrock has yet to be reached anywhere in our excavations. Within the shelter, we have uncovered probable Howiesons Poort material, with overlying late MSA and capped by late Holocene LSA. On the slope, the deepest materials are earlier MSA, overlain by assemblages with a nities to the Still Bay and Howiesons Poort. In addition to provid- ing descriptions of the lithic, faunal, and pigment assemblages, we report on the results of micromorphological analysis of the sediments and optically stimulated luminescence (OSL) and radiocarbon dating of the sequence. Based on the analysis of single-grain samples from both parts of the excavation, OSL age estimates suggest that the putative Howiesons Poort assemblages at VR003 were deposited 45.7–41.7 kya. While our results are stratigraphi- cally consistent, they are substantially younger than any previously published Howiesons Poort chronologies. We discuss the implications of these results in detail. When presenting the results of our analyses, we compare the VR003 assemblages to those from other sites in the region to address questions concerning lithic technology, stone material exploitation, chronology, ecology, and the signi cance of “complex” behaviors, such as early bead production and long distance transport of marine mollusks.

  2. Human movement is accomplished through muscle contraction, yet there does not exist a portable system capable of monitoring muscle length changes in real time. To address this limitation, we previously introduced magnetomicrometry, a minimally-invasive tracking technique comprising two implanted magnetic beads in muscle and a magnetic field sensor array positioned on the body’s surface adjacent the implanted beads. The implant system comprises a pair of spherical magnetic beads, each with a first coating of nickel-copper-nickel and an outer coating of Parylene C. In parallel work, we demonstrate submillimeter accuracy of magnetic bead tracking for muscle contractions in an untethered freely-roaming avian model. Here, we address the clinical viability of magnetomicrometry. Using a specialized device to insert magnetic beads into muscle in avian and lagomorph models, we collect data to assess gait metrics, bead migration, and bead biocompatibility. For these animal models, we find no gait differences post-versus pre-implantation, and bead migration towards one another within muscle does not occur for initial bead separation distances greater than 3 cm. Further, using extensive biocompatibility testing, the implants are shown to be non-irritant, non-cytotoxic, non-allergenic, and non-irritating. Our cumulative results lend support for the viability of these magnetic bead implants for implantation in human muscle. We thus anticipate their imminent use in human-machine interfaces, such as in control of prostheses and exoskeletons and in closed-loop neuroprosthetics to aid recovery from neurological disorders.

  3. Studies of the Eurasian Bronze Age have tended to emphasise the homogeneity of social and political processes across the Steppe, evidenced by a common ‘package’ of practices and material culture. The Dornod Mongol Survey examines the major stone monumental forms and associated features of the Ulaanzuukh mortuary tradition of the Gobi region of Mongolia. Combining evidence for mortuary and ritual practices, ceramic traditions and new radiocarbon dates, the authors argue that the appearance of the earliest Bronze Age cultures in this region represents a disparate collection of local, regional and inter-regional expressions that challenge the established narrative of a ‘standard’ Eurasian Bronze Age.

  4. Thin-film flow down a fibre exhibits rich dynamics and is relevant to applications such as desalination, fibre coating and fog harvesting. These flows are subject to instabilities that result in dynamic bead-on-fibre patterns. We perform an experimental study of shear-thinning flow down fibres using 20 different xanthan gum solutions as our working liquid. The bead-on-fibre morphology can be oriented either symmetrically or asymmetrically on the fibre, and this depends upon the surface tension, fibre diameter and liquid rheology, as defined by the Ostwald power-law index. For highly shear-thinning liquids, it is possible for the pattern to be complex and exhibit simultaneously both asymmetric large beads and symmetric small beads in the isolated and convective flow regimes. We quantify the transition between flow regimes and bead dynamics for the asymmetric morphology, and compare with Newtonian flow, as it depends upon the experimental parameters. Finally, the dimensionless bead frequency is shown to scale with the Bond number for all of our experimental data (symmetric and asymmetric).

  5. Abstract Hydrogel-encapsulated catalysts are an attractive tool for low-cost intensification of (bio)-processes. Polyvinyl alcohol-sodium alginate hydrogels crosslinked with boric acid and post-cured with sulfate (PVA-SA-BS) have been applied in bioproduction and water treatment processes, but the low pH required for crosslinking may negatively affect biocatalyst functionality. Here, we investigate how crosslinking pH (3, 4, and 5) and time (1, 2, and 8 h) affect the physicochemical, elastic, and process properties of PVA-SA-BS beads. Overall, bead properties were most affected by crosslinking pH. Beads produced at pH 3 and 4 were smaller and contained larger internal cavities, while optical coherence tomography suggested polymer cross-linking density was higher. Optical coherence elastography revealed PVA-SA-BS beads produced at pH 3 and 4 were stiffer than pH 5 beads. Dextran Blue release showed that pH 3-produced beads enabled higher diffusion rates and were more porous. Last, over a 28-day incubation, pH 3 and 4 beads lost more microspheres (as cell proxies) than beads produced at pH 5, while the latter released more polymer material. Overall, this study provides a path forward to tailor PVA-SA-BS hydrogel bead properties towards a broad range of applications, such as chemical, enzymatic, and microbially catalyzed (bio)-processes.
