umbilical cord blood (ucb) has been used for transplantation in the treatment of hematologic disorders as a source of hematopoietic stem cells (hscs). because of insufficient number of cord blood cd34+ cells, the expansion of these cells seems to be important for clinical application. mesenchymal stromal cells (mscs), playing an important role in hscs maintenance, were used as feeder layer. apo...

The concentrations of some heavy metals in sediment from the Sinop coasts of the Black Sea were measured to monitor metal pollution in 2013. The distribution of the heavy metals in sediments of the Black Sea shows a variable pattern. The objectives of the present study were to elucidate the distribution heavy metals such as Cu, Pb, Zn, Ni, Mn, Fe, As, Cd, Cr, Hg and Co in sediment from Sinop co...

Synthetic (co)polymers or (co)oligomers with two (or more) repeating groups show not only molar mass distribution, but also composition and sequence distribution of the individual repeat units. To characterize such two- (or more-) dimensional distribution, liquid chromatography under "critical conditions" has been suggested, where the separation according to one type of repeating units is suppr...

There has been a significant growth in the distributed energy resources (DERs) connected to distribution networks recent years, increasing need for modeling detail conjunction with sub-transmission/transmission networks. This paper models real distribution/ sub-transmission network using three-phase/three-sequence co-simulation. One of modeled feeders high penetration DERs reverse power flow an...

bamboo-structured carbon nanotubes are grown on co-mo/mcm-41 catalyst in the temperature range of 873-973 k by thermal chemical vapor deposition of acetylene. this study shows that the purified carbon nanotubes have open tips and the metals of the catalyst are not encapsulated. thus, the bamboo-structure seems to grow from the base. pore size distribution of the product is quite narrow and is i...
