beryllium chemical combination has a considerable effect on the design and fabrication of the241am9be neutron source. in this investigation the beryllium combinations were studied as a generator ofneutrons with various mass percentage, and the neutron yields were also calculated using the results of thealice and srim codes calculations per unit incident charge. the neutron yields of beryllium ...

Focal cortical dysplasias (FCDs) belong to the large spectrum of malformations development (MCDs) and represent most common structural brain lesion in children with drug-resistant focal epilepsies submitted surgical treatment. It is responsible for nearly half intractable epilepsy cases adults, at same time it characterized by quite good treatment outcome. We describe a case where young girl ha...

‎‎a natural generalization of two dimensional cyclic code ($t{tdc}$) is two dimensional skew cyclic code‎. ‎it is well-known that there is a correspondence between two dimensional skew cyclic codes and left ideals of the quotient ring $r_n:=f[x,y;rho,theta]/_l$‎. ‎in this paper we characterize the left ideals of the ring $r_n$ with two methods and find the generator matrix for two dimensional s...

To account for particle interactions in the extracellular (physical) environment, information from the cell-level Monte Carlo damage simulation (MCDS) for DNA double strand break (DSB) induction has been integrated into the general purpose Monte Carlo N-particle (MCNP) radiation transport code system. The effort to integrate these models is motivated by the need for a computationally efficient ...

Comme le laisse entendre la célèbre formule de Lawrence Lessig selon laquelle « code est loi », informatique qu’exécutent les ordinateurs produit des effets régulation sociale. Or, ce lui-même encadré par tout un ensemble standards techniques qui forment une sorte du dont rédaction porteuse nombreux enjeux techno-politiques débattus dans arènes spécialisées. Cet article propose pistes méthodolo...

Epilepsy-associated glioneuronal malformations (malformations of cortical development [MCD]) include focal cortical dysplasias (FCD) and highly differentiated glioneuronal tumors, most frequently gangliogliomas. The neuropathological findings are variable but suggest aberrant proliferation, migration, and differentiation of neural precursor cells as essential pathogenetic elements. Recent advan...
