The Language of Mixed Media Sculpture
No full textI was interviewed by the author about aspects of my practice (e.g. working with chance strategies and social animals). Excerpts from this interview and images of the processes and exhibited sculptures are used throughout the book.The Language of Mixed-Media Sculpture is both a survey and a celebration of contemporary approaches to sculptures that are formed from more than one material. It profiles the discipline in all its expanded forms and recognizes sculpture in the twenty-first century not as something solid and static, but rather as a fluid interface in material, time and space. It gives insightful revelations of the creative journeys of ten renowned sculptors and showcases twenty-eight international sculptors.

Sexual diversity in the judiciary in England and Wales; research on barriers to judicial careers
No full textDebates about the diversity of the judiciary in the UK have been dominated by gender, race and ethnicity. Sexuality is notable by its absence and is perceived to pose particular challenges. It is usually missing from the list of diversity categories. When present, its appearance is nominal. One effect of this has been a total lack of official data on the sexual composition of the judiciary. Another is the gap in research on the barriers to the goal of a more sexually diverse judiciary. In 2008 the Judicial Appointment Commission (JAC) for England and Wales undertook research to better understand the challenges limiting progress towards judicial diversity. A central gaol of the project was to investigate barriers to application for judicial appointment across different groups defined by “sex, ethnicity and employment status”. Sexual orientation was again noticeable by its absence. Its absence was yet another missed opportunity to recognise and take seriously this strand of diversity. This study is based on a response to that absence. A stakeholder organisation, InterLaw Diversity Forum for lesbian gay bisexual and transgender networks in the legal services sector, with the JAC’s approval, used their questionnaire and for the first time asked lesbian, gay, bisexual and transgender lawyers about the perceptions and experiences of barriers to judicial appointment. This paper examines the findings of that unique research and considers them in the light of the initial research on barriers to judicial appointment and subsequent developments
Delay Estimation for Ranging and Localization Using Multiband Channel State Information
No full textIn wireless networks, an essential step for precise range-based localization is the high-resolution estimation of multipath channel delays. The resolution of traditional delay estimation algorithms is inversely proportional to the bandwidth of the training signals used for channel probing. Considering that typical training signals have limited bandwidth, delay estimation using these algorithms often leads to poor localization performance. To mitigate these constraints, we exploit the multiband and carrier frequency switching capabilities of wireless transceivers and propose to acquire channel state information (CSI) in multiple bands spread over a large frequency aperture. The data model of the acquired measurements has a multiple shift-invariance structure, and we use this property to develop a high-resolution delay estimation algorithm. We derive the Cramér-Rao Bound (CRB) for the data model and perform numerical simulations of the algorithm using system parameters of the emerging IEEE 802.11be standard. Simulations show that the algorithm is asymptotically efficient and converges to the CRB. To validate modeling assumptions, we test the algorithm using channel measurements acquired in real indoor scenarios. From these results, it is seen that delays (ranges) estimated from multiband CSI with a total bandwidth of 320 MHz show an average RMSE of less than 0.3 ns (10 cm) in 90% of the cases.Signal Processing System
The sedimentology and depositional environment of the Beatrix Reef: Witwatersrand supergroup.
No full textA Dissertation Submitted to the Faculty of Science
University of the Witwatersrand, Johannesburg
for the Degree of Master of Science.Beatrix Mine is located 35 km south of the city of Welkom in
the Welkom Goldfield and as such forms the most southerly of
the Witwatersrand-type gold mines.
The Beatrix Reef overlies an angular unconformity at the
base of the Turffontein Subgroup, Central Rand Group
Significant, southerly truncation of over 600m of the
Johannesburg Subgroup, and the lower formations of the
Turffontein Subgroup, occur at this unconformity in the
Beatrix area..
characteristics of the Beatrix Reef conglomerates such as
the morphology, sorting and packing of clasts, and the
arrangement. of the sediments in various sedimentary
structures and facies/ sequences, suggest deposition within a
braided fluvial environment on a coarse-grained braid-delta.
Sedimentation occurred after the fluvial degradation of
previously deposited units, and culminated in a marine/
lacustrine transgression. Low aggradation rates led to
significant reworking and concentration of placer materials
in a depositional model probably typical of ventral Rand
Group placer formation. Heavy minerals (and gold) are
concentrated in response to hydraulic conditions and show a
close association with large and small scale sedimentary
features. Transport directions deduced from the sedimentary
structures suggest a north to south dispersal of sediment
down the braid plain.
Sedimentary structures in the finer rained units at the
base of the Eldorado Formation are indicative of tidal
influences and document the marine transgression as the
culmination of the degradational events.
The lithologys sedimentary structures and facies sequences
of the coarser grained units of the Eldorado Formation
well as the overall coarsening upward of these lithologies
indicate sedimentation in a braided , fluvial system, on an
alluvial fan prograding across the preyiously deposited
units" Sedimentary ~tructures and lithologic variations
confirm a continued north to south dispersal pattern.
In the area south of the Sand over the period of fluvial
degradation and transgression after the formation of the
Beatrix: Reef was followed by more rapidly aggreding fluvial
progradation due to a major change in base level in response
to compressional tectonics and uplift along the Western
Margin Structure. Only in post-Central Rand Group times did
relaxation and extensional tectonics result in the
outpourings of the Ventersdorp .supergroup lavas and the
cessation of active Witwatersrand Supergroup sedimentation.Andrew Chakane 201
The success of particular acinetobacter baumannii clones: accumulating resistance and virulence inside a sugary shield

These clonal shifts were primarily explained by an increased antimicrobial resistance profile. Here we explore genomic and biochemical differences among these and more recent clones, which could further explain the diversity and evolution of this species.info:eu-repo/semantics/publishedVersio

DIE OMSTREDE ROL VAN JAC PIENAAR IN DIE REBELLIE VAN 1914-1915
No full textThe controversial role of Jac Pienaar in the Rebellion of 1914-1915 J.J. (Jac) Pienaar was one of the lesser known leaders of the rebellion. However, behind the scenes he played a significant role both in the planning phase and in the actual rebellion itself. He was the only rebel general to plead guilty on all five counts of high treason. This study shows that he was also the only rebel leader to cooperate with Prof Leo Fouché, author of the Blue Book (UG 10-\u2715) on the rebellion. This he never admitted. In fact, his written statement to Fouché casts the first light on the planned uprising of 15 September 1914 while the relevant chapter of the Blue Book is based largely on Pienaar\u27s declaration. Unlike for example Sarel Alberts and General C.F. Beyers, Pienaar was a convinced rebel. This article attempts to determine the motives for his somewhat controversial actions.
J.J. (Jac) Pienaar is een van die minder bekende rebelleleiers. Tog het hy agter die skerms \u27n betekenisvolle rol in die beplanningsfase en in die opstand self gespeel. Voorts was hy die enigste rebellegeneraal wat op al vyf aanklagte van hoogverraad skuldig gepleit het. Uit dié studie blyk dit ook dat hy die enigste rebelleleier was wat met prof Leo Fouché, skrywer van die Blouboek (UG 10-\u2715) oor die Rebellie, saamgewerk het - iets wat Pienaar nooit erken het nie. Trouens, sy verklaring aan Fouché werp die eerste lig op die beplande opstand van 15 September 1914 en die betrokke hoofstuk in die Blouboek is grootliks op die Pienaar-verklaring gebaseer. Pienaar was, anders as byvoorbeeld Sarel Alberts en generaal C.F. Beyers, \u27n oortuigde rebel. Hierdie artikel poog om die motiewe vir sy enigsins omstrede optrede te bepaal
