The Rustenburg Layered Suite (RLS) of the Bushveld Complex in South Africa is the largest mafic–ultramafic-layered complex on Earth. The RLS is associated with marginal sills that penetrate into the ~2.2 billion-year-old sedimentary strata of the Pretoria Group. These sills are in contact and share some geochemical similarities with different zones of RLS and are classified in terms of chemical co

The Uitkomst Complex is considered to be coeval with, and genetically linked to the Rustenburg Layered Suite (RLS) of the Bushveld Large Igneous Province. This study reports new paleomagnetic, geochemical and geochronological results from the Uitkomst Complex and a crosscutting dyke at the Nkomati Mine. Primary magnetisations for the complex and the dyke are statistically indistinguishable. This,

In the wake of the economic and social crisis, Spanish fiction has looked for ways of reflecting (on) the political. One of the manners has been to attempt to understand how the crisis has affected subjectivity and, more concretely, how the subject navigates the society of the crisis. In this article, I study three recent novels—Alberto Olmos’ Ejército enemigo (2011), Bruno Galindo’s El público (2

Comparisons of the strength and form of phenotypic selection among groups provide a powerful approach for testing adaptive hypotheses. A central and largely unaddressed issue is how fitness and phenotypes are standardized in such studies; standardization across or within groups can qualitatively change conclusions whenever mean fitness differs between groups. We briefly reviewed recent relevant li

Predicted impacts of climate change on crops—including yield declines and loss of conservation lands—could be mitigated by exploiting existing diversity within crops. Here we examine this possibility for wine grapes. Across 1,100 planted varieties, wine grapes possess tremendous diversity in traits that affect responses to climate, such as phenology and drought tolerance. Yet little of this divers

This thesis collects contributions to wireline and wireless communication systems with an emphasis on multiuser and multicarrier physical layer technology. To deliver increased capacity, modern wireline access systems such as G.fast extend the signal bandwidth up from tens to hundreds of MHz. This ambitious development revealed a number of unforeseen hurdles such as the impact of impedance changes

A Scania 13 1 engine modified for single cylinder operations was run using nine fuels in the boiling point range of gasoline, but very different octane number, together with PRF20 and MK1-diesel. The eleven fuels were tested in a load sweep between 5 and 26 bar gross IMEP at 1250 rpm and also at idle (2.5 bar IMEP, 600 rpm). The boost level was proportional to the load while the inlet temperature

Neisseria meningitidis is a causative agent of meningitis. Despite vaccination programs, it still causes a large number of deaths in young children. Early diagnosis followed by passive immunization with human monoclonal antibodies could be an approach to effective therapy. Peripheral blood lymphocytes from normal, healthy blood donors and from vaccinated individuals were immunized in vitro, using

ERP systems became popular with large organizations in the 1990s. In the 21st Century, these products were expanded by addition of supply chain management (SCM) and customer relationship management (CRM), as well as access through the Web, creating the ERP II concept. Efforts to increase the market led vendors to serve not only large organizations, but also focus more on small-to-medium sized ente

Case study research plays an important role for social and political scientists working within the qualitative tradition, with the field of international relations (IR) being no exception. This article provides methodological reflections on the challenges of investigating ‘elusive’ cases within the global governance domain of IR. Taking stock of my experience of studying global multi-stakeholder p

The Gaussian β-ensemble is a real n-point configuration {xj}n1 picked randomly with respect to the Boltzmann factor e− β 2 Hn, where Hn = ∑i≠j log |xi−1xj| + n ∑ni=112 xi2. It is well known that the point process {xj }n1 tends to follow the semicircle law σ (x) = 21π√(4 − x2 )+ in certain average senses. A Fekete configuration (minimizer of Hn) is spread out in a much more uniform way in the inter

Between 1980 and 2000, a number of Sub-Saharan African countries entered into conditional structural adjustment lending arrangements with the International Monetary Fund (IMF) in response to economic crisis and decline. Despite the fact that the crises had been due in part to long-term overdependence on primary sector activities, such as cash crop agriculture and natural resource extraction, many

This study aimed to investigate how 6-bromoindirubin-3’-oxime (BIO) increases the osteogenic differentiation of canine bone mesenchymal stem cells (BMSCs) and the role of the Wnt/β-catenin signaling pathway in this process. We mimicked the effect of Wnt by adding BIO to the culture medium of BMSCs and examined whether canonical Wnt signaling positively affects the differentiation of these cells in

In this work, Piraíba and Dourada skin wastes were used for leather processing. They were initially stripped and characterized by their percentage composition. The results showed that pH, differential pH cipher [SLC13/ IUC 11/ BS 1309:9 - Determination of pH value and Difference Figure of an Aqueous Extract], chromium content and mechanical properties after chromium tanning were in accord with lea

Wastewater generated in tanneries have essential elements for microalgae growth, but it has also some toxic compounds that may hinder or restrain the growth of microalgae in this environment. This work tested microalgae consortium growth originating from a deactivated effluent treatment decanter of a complete tannery (beamhouse to finished leather) for the treatment of wastewater of a tannery proc

Progressive myoclonus ataxia (PMA) is a rare clinical syndrome characterized by the presence of progressive myoclonus and ataxia, and can be accompanied by mild cognitive impairment and infrequent epileptic seizures. This is the first study to describe the natural history of PMA and identify clinical, electrophysiological, and genetic features explaining the variability in disease progression. A D

Background: Radiostereometric analysis (RSA) provides highly accurate data about the migration of a total knee arthroplasty (TKA) component. However, patient-reported outcome measures (PROMs) reflect the patients' perspective of their functional status, pain, and overall health after TKA. The aim of this study was to evaluate the association between tibial implant migration and change in postopera
