Topological properties

This paper studies the formal local cohomology with respect to non-maximal ideals. It is an extension of the formal local cohomology for maximal ideals by Schenzel (2007). By using the properties of inverse limits and I-adic topology, we have proved several crucial properties of the formal local cohomology of order 0 regarding non-maximal ideals.

Once the mechanical properties of printed TPU are characterised, a novel, low cost, and environmentally friendly method for concrete casting using printed TPU moulds is proposed in this thesis. Additively manufactured TPU mould is developed to cast complex concrete structures. A planar topologically optimized cantilever and a free-form 3D column are cast using the proposed TPU mould. Good surface quality is obtained for the cast concrete elements, and the moulds can be reused many times after cleaning.

Characterization with FTIR, powder X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, and atomic force microscopy confirmed the successful synthesis of nanocomposites with good dispersion of nanoparticles in the polymer matrix. Both field emission scanning electron microscope and transmission electron microscope analyses showed that the cerium oxide was well dispersed in the PAA matrix; it was dispersed in the PAA matrix on a nanometer scale.

Antioxidative activity of chrysin (CYS) on the B12N12 nanocage has been evaluated by density functional theory with B3PW91-D3 and M06-2X-D3 methods. Adsorption behavior and study of topologies demonstrated that the CYS has chemisorbed to the nanocage and shows notable changes in the electronic properties of B12N12. The antioxidant properties of the CYS and CYS/B12N12 systems have been studied in the different environments by the M06-2X-D3 method.

Minimum dominating sets (MDSet) of protein interaction networks allow the control of underlying protein interaction networks through their topological placement. While essential proteins are enriched in MDSets, we hypothesize that the statistical properties of biological functions of essential genes are enhanced when we focus on essential MDSet proteins (e-MDSet).

Autophagy is a conserved molecular pathway involved in the degradation and recycling of cellular components. It is active either as response to starvation or molecular damage. Evidence is emerging that autophagy plays a key role in the degradation of damaged cellular components and thereby affects aging and lifespan control.
