Alles gebeurt opeens heel snel. Uit een taxi springt een dikke man met een riotgun in zijn hand. Kalm richt hij zijn geweer op Malko''s auto. Malko grijpt Héloise en duwt haar tegen de bank, net voordat een regen van kogels de voorruit kapot slaat. Op de tast vindt Malko de deurkruk en laat zich snel naar buiten glijden. Wanneer hij opkrabbelt, staat hij oog in oog met een grote Arabier, die ook een geweer in zijn hand heeft. De loop is op Malko gericht...

The approximation of a continuous function by either an algebraic polynomial, a trigonometric polynomial, or a spline, is an important issue in application areas like computer-aided geometric design and signal analysis. This book is an introduction to the mathematical analysis of such approximation, and, with the prerequisites of only calculus and linear algebra, the material is targeted at senior undergraduate level, with a treatment that is both rigorous and self-contained. The topics include polynomial interpolation; Bernstein polynomials and the Weierstrass theorem; best approximations in the general setting of normed linear spaces and inner product spaces; best uniform polynomial approximation; orthogonal polynomials; Newton-Cotes , Gauss and Clenshaw-Curtis quadrature; the Euler-Maclaurin formula ; approximation of periodic functions; the uniform convergence of Fourier series; spline approximation,with an extensive treatment of local spline interpolation,and its application in quadrature. Exercises are provided at the end of each chapter

Eleven years ago the circular DNA of a novel single-stranded virus has been cloned and partially characterized by Nishizawa and Okamoto and their colleagues. According to the initials of the patient from whom the isolate originated, the virus was named TT virus. This name has been subsequently changed by the International Committee on Taxonomy of Viruses (ICTV) into Torque teno virus, permitting the further use of the abbreviation TTV. Although initially suspected to play a role in non A –E hepatitis, subsequent studies failed to support this notion. Within a remarkably short period of time it became clear that TT viruses are widely spread globally, infect a large proportion of all human populations studied thus far and represent an extremely heterogeneous group of viruses, now labelled as Anelloviruses. TT virus-like infections have also been noted in various animal species. The classification of this virus group turns out to be difficult, their DNA contains between 2200 and 3800 nucleotides, related so-called TT-mini-viruses and a substantial proportion of intragenomic recombinants further complicate attempts to combine these viruses into a unifying phylogenetic concept.

The main focus of this book is on actively engaging students in the mathematical processes of modeling and axiomatization. The book starts off with some challenging problems involving switching circuits. Students are then engaged in gradually developing a mathematical model in order to solve these problems. Suitable notation is firstly introduced for series and parallel switches, and then followed by truth tables, and the discovery of several interesting mathematical properties related to switching circuits.After development of the model and solution of the original problems, a section on systematization follows where students are led through some proof activities to identify a suitable set of axioms. The book concludes with a short historical overview of the development and application of Boolean Algebra.

The inspiring story of Graça Machel, and her dream to instill a love for reading and learning in the children of Mozambique and the rest of Africa.

Malko aperçut sa Honda blanche garée le long du Holiday Inn. Il allait prendre sa clef lorsque son regard glissa jusqu''au véhicule garé devant sa voiture. Son sang se figea en une fraction de seconde. C''était la Cherokee blanche, celle qui contenait les 500 kilos de TNT. Il n''osait même plus bouger, comme si le moindre déplacement d''air allait déclencher l''explosion. Puis, son cerveau se remit en route. Tout près, peut-être sur le trottoir d''en face, quelqu''un attendait qu''il soit arrivé pour appuyer sur le bouton.

Un cargo chargé d''armes est attaqué par des pirates somaliens. Le commandant réussit à photographier l''un d''eux. La photo parvient à la CIA qui découvre ainsi que les pirates somaliens se sont alliés aux « Shebabs », les taliban somaliens et qu''ils préparent des actions terroristes. Malko, qui a déjà travaillé sur la Somalie file au Kenya, base arrière des pirates. Après avoir été kidnappé par leurs complices, il découvre que la seule « source » capable de les renseigner se trouve à Mogadiscio, l''endroit le plus dangereux du monde. Il s''y rend en compagnie d''une « stringer » somalienne de la CIA, Hawo et parvient à contacter la « source », qui sert désormais d''interprète aux pirates. Ce dernier promet de le rejoindre à Mombasa, dès qu''il aura l''information.Ce qu''il fait, mais les shebabs l''ont surveillé et il est abattu avant d''avoir pu parler à Malko. Cependant, son dernier geste, avant de mourir, permet à Malko de déduire le nom du bateau qui doit être attaqué : un énorme « gazier », qui transporte 80.000m3 de gaz liquéfié. Une bombe.

Tsunami, earthquake, hurricane, pandemic—are these and other natural calamities more probable, and more frequent, than they were? Are things getting worse? De Villiers examines these questions in a time when we truly need to understand the dangers ahead and how to act in such a way that we''re preparing for the inevitable and not making things worse.

This book provides a lucid and entertaining account of the child''s entrance in the world of language. By means of amusing and informative examples, the authors describe the language acquisition process, from birth to school age, showing how children gradually master the intricacies of sounds, words, rules, and concepts.

Malko regarda autour de lui et aperçut aussitôt, le long d''une rame à l''arrêt, deux jeunes Chinois. L''un tenait un fléau : un bâton prolongé d''une chaîne, elle-même se terminant par une longue pointe aiguisée. L''autre se préparait à lui lancer une étoile à cinq branches, avec un trou au milieu. L''arme des triades. Terrible. Qui, à vingt mètres, vous tuait silencieusement. Comme il était sorti parmi les derniers, il n''y avait pratiquement plus personne avec lui. Un des deux Chinois rejeta le bras en arrière et, se détendant comme pour un lancer de javelot, projeta une seconde "étoile" qui tournoya à une vitesse diabolique, droit vers Malko.

Malko doorzocht een deel van het kerkhof, maar Joachim zag hij nergens. Toen hij naar de ingang liep, hoorde hij het grind achter zich knersen en keek hij om. Joachim de grafdelver kwam als een wildeman op hem af stormen, zijn grote machete in zijn hand. Zijn witte tanden waren zichtbaar in een hatelijke grijns. Hij hoef de machete op en slaakte een soort woest gegrom, klaar om op Malko in te hakken. .

International law is rich in promise but poor in detail and practical application about the rights of indigenous people. This book focuses on practical measures that have been implemented in states to give effect to free, prior and informed consent (FPIC); self-determination by indigenous people; special electoral measures to benefit indigenous people; and the role of advisory bodies to advocate for indigenous interests. In many comparative works there are often only scant or brief reference to some country-experiences, but in this book several case studies are explored in depth to promote a greater understanding of the self-determination arrangements that have been implemented. These case studies represent a form of glocalisation, whereby global principles are applied to find local solutions, and local solutions in turn inform greater clarity and specificity to global principles. At the end of each chapter key lessons that can be drawn from the respective case studies are identified in the hope that those may inform developments in other countries and in international law.

Le premier barreau se détacha. Au même moment, une vingtaine de rats porteurs des germes de la peste avancèrent en couinant. Malko saisit le barreau et le brandit. Les rats ne reculèrent pas. S''ils attaquaient tous ensemble, c''était fini. On voyait leurs petites gueules roses s''ouvrir et se fermer. - Ils ont faim... dit Felipe.
