Durable Left Ventricular Assist Device Therapy for End-stage Heart Failure:Optimizing selection criteria
This thesis has been an effort to improve the outcomes of patients suffering from end-stage heart failure treated with left ventricular assist device (LVAD) therapy. Moreover, this thesis aimed to assess and thereafter accurately predict the onset of adverse events to aid in future patient selection criteria. Although outcomes following LVAD implantation have greatly improved since its introduction, further research is paramount for the ongoing success of this treatment modality

Influence of water on the surface of graphene
We have studied how water modifies the surface of graphene and in particular how the surface conductivity of graphene is affected. According to the literature, two types of interactions should be distinguished: physical, where a water molecule remains intact and is located at some distance from the mesh, and chemical, where a water molecule is imbricated in the graphene bond structure. We have developed theoretical models for both types of interactions using the density functional theory (DFT) with the B3LYP hybrid functional combined with the 6-31G(d) basis set. Our calculations show that the surface conductivity of graphene is reduced in the presence of water

Noble gas cluster ions
In this work, a reaction mechanism of formation of noble gas (Ng) cluster ions has been theoretically investigated in detail. The kinetic studies of formation of XeXe cluster in Xe, ArAr cluster ions in Ar, and NeNe cluster ions in Ne have been made as theoretically. The optimized structures in the ground state were calculated using the density functional theory (DFT) by the B3LYP method combined with the Stuttgart/Dresden effective core potential basis set (SDD). In addition, we calculated the rate constants of all cluster formations. The results are /s, respectively for Neon, Argon, Xenon cluster ions
