Umbilical cord blood is the baby's blood left over in the umbilical cord and placenta after a baby is delivered and the cord is cut. Cord blood has all of the features of regular blood, but it is also a rich source of hematopoietic stem cells. Hematopoietic stem cells are unspecialized cells that produce all blood cells. These include: • Platelets, which are needed for blood clotting • Red...

In this paper, a novel method for MRI volume segmentation based on region adaptive splitting and merging is proposed. The method, called Adaptive Geometric Split Merge (AGSM) segmentation, aims at finding complex geometrical shapes that consist of homogeneous geometrical 3D regions. In each volume splitting step, several splitting strategies are examined and the most appropriate is activated. A...

This work describes a simple yet powerful scalable solution chemistry strategy to create back-contact rich interfaces between substrates such as commercial transparent conducting fluorine-doped tin oxide coated glass (FTO) and photoactive thin films hematite for low-cost water oxidation reaction. High-resolution electron microscopy (SEM, TEM, STEM), atomic force (AFM), elemental chemical mappin...

Duplicating centrosomes are paired during interphase, but are separated at the onset of mitosis. Although the mechanisms controlling centrosome cohesion and separation are important for centrosome function throughout the cell cycle, they remain poorly understood. Recently, we have proposed that C-Nap1, a novel centrosomal protein, is part of a structure linking parental centrioles in a cell cyc...

consider the linear system ax=b where the coefficient matrix a is an m-matrix. in the present work, it is proved that the rate of convergence of the gauss-seidel method is faster than the mixed-type splitting and aor (sor) iterative methods for solving m-matrix linear systems. furthermore, we improve the rate of convergence of the mixed-type splitting iterative method by applying a precondition...

to assess the interaction effects of weeds, sowing rate, and n splitting on dryland wheat yield, field experiments were conducted in two years (2007 and 2009) at the college of agriculture in shiraz university. the treatments were replicated four times and analyzed as a split- split plot in a randomized complete block. the weedy and weed free were treated as the main plots, the wheat sowing rat...

over the last ten years, robustness of schemes has raised an increasing interest among the cfd community. the objective of this article is to solve the quasi-one-dimensional compressible flow inside a “shubin nozzle” and to investigate bean-warming and flux vector splitting methods for numerical solution of compressible flows. two different conditions have been considered: first, there is a sup...
