Permeability, the ability of rocks to flow hydrocarbons, is directly determined from core. Due to high cost associated with coring, many techniques have been suggested to predict permeability from the easy-to-obtain and frequent properties of reservoirs such as log derived porosity. This study was carried out to put clustering methods (dynamic clustering (DC), ascending hierarchical clustering ...

cet article est consacréà l’étude du dialogue dans enfance, récit autobiographique de nathalie sarraute qui contient des souvenirs de ses onze premières années. l’une des originalités de ce récit, se base sur la présence de deux voix narratives qui dialoguent tout au long du récit. l’une de ces dernières, joue le rôle d’une narratrice et l’autre représente le côté conscient de l’auteur qui suiv...

Methylated and un-methylated control DNA is an important part of DNA methylation studies. Although human and mouse DNA methylation control sets are commercially available, in case of methylation studies on other species such as animals, plants, and bacteria, control sets need to be prepared. In this paper a simple method of generating methylated and un-methylated control DNA is described. Whole...

in order to study the effects of herbicide rates of metribuzin on nodulations and growth characteristics of chickpea, a series of experiments were carried out at research greenhouses of ferdowsi university of mashhad during 2009 in a randomized complete block design with four replications. studied factors were: different doses of metribuzin herbicide (10- 25- 50- 75- 100- 125 percent of recomme...

The purpose of this work is to study the effect of oscillatory MHD blood flow in stenosed artery. The analytical and numerical results are obtained for oscillatory MHD blood flow, which is assumed to be a Newtonian fluid. It was also assumed that the surface roughness is of cosine shaped and the maximum height of roughness is negligible, compared with the radius of un-constricted tube. The flui...

Standard e-business document types are usually too ambiguous due to an overwhelming choice of data elements. Business partners must agree on a shared subset and adapt their application interfaces accordingly. Small and medium enterprises (SMEs) cannot perform this task. UN/CEFACT’s Modeling Methodology (UMM) provides a methodology to define unambiguous business collaborations allowing software ...

RÉSUMÉ. La construction de logiciels à partir de plusieurs applications différentes et hétérogènes est de plus en plus fréquente. Cependant, il n’existe pas à présent une méthodologie de construction pour de tels logiciels. Dans cet article, nous proposons une architecture qui permet de créer des logiciels en faisant collaborer plusieurs services et applications différentes et hétérogènes, util...

In an earlier paper it was argued that two sequences, denoted by {Un} and {Wn}, constitute the sextic analogues of the well-known Lucas sequences {un} and {vn}. While a number of the properties of {Un} and {Wn} were presented, several arithmetic properties of these sequences were only mentioned in passing. In this paper we discuss the derived sequences {Dn} and {En}, where Dn = gcd(Wn − 6R n, U...
