fifty years ago warren and root have introduced the shape factor. this fundamental parameter for modeling of naturally fractured reservoirs has been discussed stormily ever since. different definitions for shape factor have been suggested which all of them are heuristically based. recently, heinemann and mittermeir mathematically derived - based on the dual-continuum theorem assuming pseudo-ste...

Spontaneous bacterial peritonitis (SBP) is defined as an ascitic fluid infection without a surgically-treatable intra-abdominal source. Timely diagnosis and treatment of SBP may increase the patient’s survival.1 Any biological marker that could strongly predict SBP may obviate the need for paracentesis while increasing the patient’s chance of survival by expediting the diagnosis and treatment o...

Trees are defined as connected graphs without cycles, and their properties are basics of graph theory. A tree on n nodes labeled 1, 2,..., n is a recursive tree if the node labeled 1 is distinguished as the root, and for each 2 ≤ k ≤ n, the labels of the nodes in the unique path from the root to the node labeled k form an increasing sequence [6]. Bucket trees are a generalization of the ordinar...

Telomeres are the structures that protect eukaryotic chromosomes in the cells. Telomeres are necessary components that stabilize the ends of eukaryotic chromosome and avoid the loss of genetic information (Parkinson, 2003). Meanwhile, telomerase is a reverse transcriptase that adds nucleotide repeats to telomeres by using RNA template providing karyotype stability and compensating for the loss ...

The process of optical imaging and the use of a glass lens have been hitherto inseparable since it is the lens that is responsible for mapping incoming rays to form an image. While performing this critical role, the lens, by virtue of its geometry and materials composition, presents constraints on the size, weight, angular field of view, and environmental stability of an optical imaging system ...

INTRODUCTION A comprehensive understanding of adolescent development requires investigation into both normative patterns and individual differences in the full range of developmental domains. Extensive research in adolescent development has focused on delineating trajectories of typi· cal development and understanding how those vary based on gender, culture, and socioeco­ nomic context. Very fe...
