dendrimer synthesis strategies now provide virtual control of macromolecular nanostructures as a function of size and surface/interior functionality. these strategies involve the covalent assembly of hierarchical components reactive monomers , branch cells or dendron’s around atomic or molecular cores according to divergent/convergent dendrite branching principles.combinon of two or more dendri...

Blood vessels have been shown to play perfusion-independent roles in organogenesis. Here, we examined whether blood vessels determine branching stereotypy of the mouse lung airways in which coordinated branching of epithelial and vascular tubes culminates in their co-alignment. Using different ablative strategies to eliminate the lung vasculature, both in vivo and in lung explants, we show that...

In this research the exclusive decay of                         is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the  decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...

Regional development policies based on regions’ core strengths is key for innovative and competitive growth. For sustainable growth, each region would discover their own growth paths grounded knowledge base capabilities. Although there are studies that focus regional clustering of economic activity technological dispersion sectors in Turkey, little known related to the potential attract new tec...

A major structure/function relationship in the eye lens is that between the constituent proteins, the crystallins and the optical property of refractive index. Structural breakdown that leads to cataract has been investigated in a number of studies; the concomitant changes in the optics, namely increases in light attenuation have also been well documented. Specific changes in the refractive ind...
