Informal borrowings can be divided into three main thematic types: core, culture-specific, and miscellaneous. The core themes, shared with those in general informal language, make up the majority of borrowings and include such themes as evaluative categorization, the human body, sex, and intoxication. The culture-specific themes, inherent to immigrants and minorities, include borrowings connected with minority experiences but also racial discrimination and geography viewed from their perspective. The miscellaneous themes, constituting an all-inclusive collection, include as many as 150 themes grouped under several superordinate divisions. Their diversity and size illustrates the thematic scope of informal borrowings and demonstrates that they are not a marginal part of lexicon but can be used to refer to numerous aspects of human experience.
Acute and chronic tonsillitis are frequently treated with antibiotics. This study aimed to understand the presence of pathogenic micro-organisms on the surface and core of chronically infected tonsils among Tanzanian children.
Methods
The study enrolled children undergoing adenotonsillectomy. Surface and core tonsillar swabs were taken. Quantitative polymerase chain reaction was performed for Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Staphylococcus aureus, Neisseria meningitidis and Pseudomonas aeruginosa.
Results
Surface and core combined, isolated N meningitidis (86.1 per cent) was found the most, followed by H influenzae (74.9 per cent), S pneumoniae (42.6 per cent) and S aureus (28.7 per cent). M catarrhalis and P aeruginosa were only found in a few patients, 5.6 per cent and 0.8 per cent respectively.
Conclusion
Colonisation of the tonsillar surface and core has been found. Potentially pathogenic micro-organisms are likely to be missed based on a throat swab. Hence, the practice of surface tonsillar swabbing may be misleading or insufficient.
The appraisal and development of fractured reservoirs are challenging tasks because of the combined variations in reservoir quality and natural fracture distribution. Fracture models are built routinely to support both appraisal and development decisions for such reservoirs. One of the key objectives of these models is to generate three-dimensional (3D) fracture properties for dynamic flow simulations. In this paper, we illustrate the discrepancy between the scale of observation required to build a thorough geological understanding of the subsurface and the simplification imposed by modelling. We use a case study carried out in the context of an exploration campaign of a Cretaceous carbonate reservoir in Egypt. After describing the regional geological setting of the area, we share a series of detailed observations on open-hole logs, cores, thin-sections and borehole images. These observations are focused on reservoir architecture, fracture typology and fracture connectivity. Observations are then integrated with the regional geological context to build a conceptual fracture model and to characterize the uncertainty affecting the essential parameters of this model. The conceptual model, combined with 3D seismic data, is used to define a fracture modelling strategy. This strategy includes a drastic simplification of the conceptual model to generate 3D discrete fracture network scenarios that are calibrated using pressure communication data from the exploration wells. Another extreme simplification is then necessary to populate 3D simulation grids. In the case study presented, the key tuning parameters to obtain a dynamic match are the grid cell orientation and the width of the modelled fault damage zone.
The key to parallel programming is sharing a task between many cooperating threads running in parallel. A chart is presented showing how since 2003 the Moore’s law growth in computing performance has depended on parallel computing. This chapter includes a simple introductory CUDA example which performs numerical integration using 1000 000 000 threads. Using CUDA gives a speed-up of about 1000 compared to a single CPU thread. Key CUDA concepts including thread blocks, thread grids and warps are introduced. The hardware differences between conventional CPU architectures and GPUs are then discussed. Optimisations in memory caching on GPUs are also explained as memory access time is often a key performance constraint for many programs. The use of OpenMP to share a single task across all cores of a multicore CPU is also discussed.
As the Republican Party narrowed and weakened in the late 20t century, it became home to a succession of conservative movements which largely defeated the party’s moderate wing, lent it a more ideological coloration, and initiated the sharp polarization in American politics that lasted into the early 21st century.
The chapter surveys the literature and approaches that deal with the economics and politics of managing internationally shared water resources (aka transboundary water). Principles that are relevant to the analysis of management of shared international water are discussed and demonstrated. One aspect that is unique to international water is the use of agreements between all or part of the riparian states that share the basin. The chapter introduces several means by which cooperation among the riparian states is defined and calculated, using the information embedded in the treaties that they signed. The chapter provides also an example, applied to the case of the Blue Nile Basin, of the effect of using certain allocation methods on the welfare of the river basin riparian states, Ethiopia, Sudan, and Egypt, and its effects on the stability of their allocation agreement.
The chapter presents the specific art approach to HCI research, including an illustration from the literature. The latter claims that empirical investigations of videogame play and videogame engagement are often delimited along demographic or genre lines. In contrast, the illustration proposes a theory of players engaging with games, if they can find a sense of net personal cultural value.The chapter then presents the specific art framework for HCI research, comprising art as discipline, general problem, particular scope, research, knowledge and practices. The specific art framework is followed by the art design research exemplar, as the art design cycle and the art design research cycle. The lower-level art framework comprises the art application, the art interactive system, and the art interactive system performance. Both the exemplar and the lower-level framework are applied to the same illustration of the art approach taken from the literature, which proposes a theory of players engaging with games, if they can find a sense of net personal cultural value.

This article explores how Qin Dynasty bureaucrats attained accuracy and precision in producing and designing measuring containers. One of the salient achievements of the Qin empire was the so-called unification of measurement systems. Yet measurement systems and the technological methods employed to achieve accuracy and precision in ancient China have scarcely been explored in English-language scholarship. I will examine the material features of the containers and reconstruct the production methods with which the clay models, molds, and cores of the containers were prepared before casting. I also investigate the inscriptions on the containers to determine whether they were cast or engraved. In so doing, I supply the field of Qin history with additional solid evidence about how accuracy and precision were defined in the Qin empire.
This chapter studies the properties of environmental externality from general equilibrium perspective in the four basic models --- SEEE, SEEN, DEEE, and DEEN models. The chapter establishes the key results of environmental externality provision. They are the triangular equivalence relationship among the Lindahl equilibrium without transfer, the Nash bargaining solution with the payoffs of Cournot-Nash equilibrium as the status quo point, and the social optimum under the Lindahl weights. In this framework, the mapping of efficient solutions of the models and the simplex of social welfare weights plays a critical role. To facilitate the application of these results in empirical research, we provide analytical and numerical examples to validate these results as well as the algorithmic approach to solve the solution concepts derived from the key results. In contrast to the Lindahl equilibrium, we also critically assess the popular Benthamite and Negishi solutions of environmental externality provisions as well as transfer issues. In the appendix, we offer the programming codes in GAMS language for the numerical example.
We introduce a dimension group for a self-similar map as the
$\mathrm {K}_0$
-group of the core of the C*-algebra associated with the self-similar map together with the canonical endomorphism. The key step for the computation is an explicit description of the core as the inductive limit using their matrix representations over the coefficient algebra, which can be described explicitly by the singularity structure of branched points. We compute that the dimension group for the tent map is isomorphic to the countably generated free abelian group
${\mathbb Z}^{\infty }\cong {\mathbb Z}[t]$
together with the unilateral shift, i.e. the multiplication map by t as an abstract group. Thus the canonical endomorphisms on the
$\mathrm {K}_0$
-groups are not automorphisms in general. This is a different point compared with dimension groups for topological Markov shifts. We can count the singularity structure in the dimension groups.
Stone tools are the least familiar objects that archaeologists recover from their excavations, and predictably, they struggle to understand them. Eastern Africa alone boasts a 3.4 million-year-long archaeological record but its stone tool evidence still remains disorganized, unsynthesized, and all-but-impenetrable to non-experts, and especially so to students from Eastern African countries. In this book, John J. Shea offers a simple, straightforward, and richly illustrated introduction in how to read stone tools. An experienced stone tool analyst and an expert stoneworker, he synthesizes the Eastern African stone tool evidence for the first time. Shea presents the EAST Typology, a new framework for describing stone tools specifically designed to allow archaeologists to do what they currently cannot: compare stone tool evidence across the full sweep of Eastern African prehistory. He also includes a series of short, fictional, and humorous vignettes set on an Eastern African archaeological excavation, which illustrate the major issues and controversies in research about stone tools.
World-systems analysis is a holistic and critical social science approach that proposes the study of social change focusing on whole systemic human interaction networks. The general theoretical approach is based on institutional materialism that is inspired by classical sociology and anthropology (Chase-Dunn and Lerro 2016). The world-system perspective emerged in the 1960s and 1970s to explicate the nature of the core–periphery hierarchy over the last five centuries.
On the centenary of the International Union of Geodesy and Geophysics, this book reviews the state-of-the-art research in geomagnetism, aeronomy and space weather. Written by eminent researchers from these fields, it summarises the advances in research over the past 100 years, and looks ahead to current and emerging studies on Earth's magnetic field. It provides a comprehensive overview of the generation of Earth's magnetic field, its history and its response to external forces. Starting at the centre of the Earth, the reader is taken on a journey from the interior core and mantle, through the upper atmosphere and magnetosphere, before reaching the Sun's atmosphere and corona. The applications of this research are also discussed, particularly the societal impact of solar activity on critical infrastructures in our increasingly technologically dependant society. This book provides a valuable resource and reference to academic researchers and students in geomagnetism and aeronomy.
The concept of the “essence”—as well as the related concepts of “substance” or “core”—of fundamental rights is absent from the text of the European Convention on Human Rights (ECHR), but regularly appears in the case law of the European Court of Human Rights (ECtHR) since the Belgian Linguistic case of 1968. Yet, fifty years after its explicit emergence in the Convention’s legal order, it must be observed that a clear understanding of this concept and of its practical utility is still lacking. Indeed, the idea of the essence of fundamental rights has never been clearly defined in its case law, which remains essentially pragmatic and unprincipled in this field. This Article will therefore attempt to remedy this shortcoming by sketching out the different functions assigned to the concepts of the essence, substance, and core of rights in the ECtHR’s case law. It is postulated that the concepts of the essence, substance, and core of fundamental rights are invoked for three different types of purposes. First, the concepts of the essence, substance, and core are—apparently at least—used by the ECtHR to fix the “limit on the limits,” for example, the inalienable part of fundamental rights safeguarded from any possible restriction. Second, this concept has been a vehicle for expanding the Convention’s sphere of protection for the purposes of guaranteeing its effectiveness. Third, the concepts of the essence, substance, and core of fundamental rights also constitute a “reviewing tool” used by the Court to determine the intensity of the States’ obligations on the basis of a prioritization among a series of values at stake. Although these three different functions can be identified on paper, the practical usefulness, workability, and desirability of the concepts of the essence, substance, and core will be questioned.
Ultrahigh-pressure and -temperature (P-T) experimental techniques have progressed rapidly in recent years. By combining them with X-ray diffraction measurements at synchrotron radiation facilities, it is now possible to examine deep Earth mineralogy in situ at relevant high P-T conditions in a laser-heated diamond anvil cell (DAC). The lowermost part of the mantle, known as the D″ layer, has long been enigmatic because of a number of unexplained seismological features. Nevertheless, the discovery of a phase transition from MgSiO3 perovskite to ‘post-perovskite’ above 120 GPa and 2400 K indicates that post-perovskite is a principal constituent in the lowermost mantle, which is compatible with seismic observations. The ultrahigh P-T conditions of the Earth’s core have not been accessible by static experiments, but the structure and phase transition of Fe and Fe-alloys are now being examined up to 400 GPa and 6000 K by laser-heated DAC studies.
