It is remarkable that the founders of African nations lamented the destruction of African civilisations by slavery and colonisations and yearned for the rebirth of Africa. From the outset these African leaders though subscribing to foreign ideologies and religions recognised and acknowledged the distinctive features of the African personality and world-view and aspired to build a new Africa bas...

This paper presents two strong distinguishers for the deterministic random bit generator ISAAC, requiring 2 and 2 samples of respectively 64 and 32 bits, based on the observation that more than 2 167 initial states among the 2 192 ones induce a strongly non-uniform distribution of the bits produced at the first round of the algorithm. A previous attack on ISAAC presented at Asiacrypt’06 by Paul...

This is an expanded version of the notes of my three lectures at a NATO Advanced Study Institute “Symmetric functions 2001: surveys of developments and perspectives” (Isaac Newton Institute for Mathematical Sciences, Cambridge, UK; June 25 – July 6, 2001). Lecture I presents a unified expression from [4] for generalized Littlewood-Richardson coefficients (= tensor product multiplicities) for an...

Alumina nanomaterials were synthesized via a solution combustion technique using tris-(acetylacetonato) aluminum(III) complex (1) and tris-(2-formylphenolate) aluminum(III) complex (2) at 600, and 1000 °C for 3h. The obtained data showed that the procedure without using fuel resulted in a better phase and morphology. To investigate the phase formation, powder X-ray diffraction technique was use...

BACKGROUND Childhood obesity and asthma are increasing worldwide. A possible link between the two conditions has been postulated. METHODS Cross-sectional studies of stratified random samples of 8-12-year-old children (n = 10 652) (16 centres in affluent and 8 centres in non-affluent countries) used the standardized methodology of ISAAC Phase Two. Respiratory and allergic symptoms were ascerta...
