A rock mass is a material quite different from other structural materials used in civil engineering. It is heterogeneous and quite often discontinuous, but is one of the materials in the earth's crust, which is most used in man's construction. Ideally, a rock mass is composed of a system of rock blocks and fragments separated by discontinuities forming a material in which all elements behave in...

i) ‘English is neutral’ since no cultural requirements are tied to the learning of English, [...] English belongs to everyone or no one, or at least is quite often regarded as having this property. Ronald Wardhaugh (1987) ii) ‘English is imperialist’ What is at stake when English spreads is not merely the substitution or displacement of one language by another [...] from an awareness of this as...

In this paper, we describe improvements to the function field sieve (FFS) for the discrete logarithm problem in Fpn , when p is small. Our main contribution is a new way to build the algebraic function fields needed in the algorithm. With this new construction, the heuristic complexity is as good as the complexity of the construction proposed by Adleman and Huang [2], i.e Lpn [1/3, c] = exp((c ...

BACKGROUND AND AIMS Regulation of electronic cigarettes has moved to the top of the addiction policy agenda, as demonstrated by the recent focus across the United Kingdom on introducing age-of-sale restrictions. However, the views of those affected by such regulation remain largely unexplored. This paper presents the first detailed qualitative exploration of adolescents' perceptions of existing...

With great interest we read the recently published guidelines of European Resuscitation Council (ERC) on adult cardiopulmonary resuscitation (CPR).1Perkins G.D. Graesner J.-T.

Recently, the global carbon footprint issue is rising significantly due to fossil fuel demand. Biohythane, which produced from anaerobic digestion found as an alternative address this problem. Even though quite a number of reviews have been done before on biohythane production process, in-depth review particularly kinetic study not available until now. Therefore, paper discusses general process...

The original problem of supervised classification considers the task of automatically assigning objects to their respective classes on the basis of numerical measurements derived from these objects. Classifiers are the tools that implement the actual functional mapping from these measurements—also called features or inputs—to the so-called class label—or output. The fields of pattern recognitio...
