چکیده
Tiapoumdepartment is located in the southeast of onshore basin Cote dIvoire. The sedimentological, granulometric and morphoscopic analyzes carried out on 24 samples from two wells made it possible to determine lithological, paleoenvironmental evolution sediments this area. lithological characterization revealed four facies department Tiapoum. We therefore have direction sedimentation, a thick layer clay-sandy, sands intercalated with ferruginous sandstone absent at Aby crossroads land bar which thins upstream downstream. As for particle size analysis, reveals that Tiapoum were deposited by free accumulation. These are well very graded predominance medium grains an asymmetry towards fine grains. They fluvial-type environment transported mainly suspension rolling sometimes saltation. Morphoscopy quartz abundance sub-angular sub-rounded shiny blunt appearance showing fractures or cracks due shocks between during transport. come distal environments water. prevailed deposit oxidized continental type reworked places.

la mer caspienne est un bassin isole de type lacustre. son regime sale depend de l'influence de l'eau douce et de l'evaporation de la nappe d'eau. la masse principale des sels vient des bassins qui occupaient son auge au pliocene et au pleistocene. cependant, des la fin du pliocene (i'age apcheron), la mer caspienne formait deja un bassin d'eau saumatre. au cours d...

The Modifiable Areal Unit Problem (MAUP) is a well-known issue related to the influence of the spatial support on statistical observations. It occurs when different spatial units making different spatial partitions are used and when the resulting measures vary according to those partitions. In this paper, we first draw a state of the art. Considering the particular problem of (up)scaling, we pr...

We are interested in nite-time blow-up phenomena for heat equations of the type: @u @t = u+ jujp 1u (1) where u : (x; t) 2 RN [0; T )! R, 1 < p, (N 2)p < N + 2. We rst construct for (1) a solution u which blows-up in nite time T at only one blow-up point x0 2 RN , and describe completely its blow-up pro le (or asymptotic behavior). This construction is based on a priori estimates' technique whi...
