Abstract This manuscript reports the investigation of polymorphic behaviour fipronil using a systematic comparison thermochemical and structural properties different crystal forms obtained in this study as well those previously reported literature. The analytical techniques employed include DSC, TGA, PXRD, SCXRD hot stage microscopy. DSC proved particularly useful because it made possible to di...

In recent years, active filters have been considered and developed for elimation of harmonics in power networks. Comparing with passive, they are smaller and have better compensating characteristics and resistance to line distortions. In this paper, a novel idea based on adaptive filter theory in presented to develop an active filter to eliminate the distortions of an arbitrary signal. Using th...

Polymer-modified bitumen (PMB) is a high-performance material for road construction and maintenance. But its storage stability and phase separation behaviour are still not sufficiently understood and need to be studied toward a more successful and sustainable application of PMB. In this thesis, the equilibrium thermodynamics and phase separation dynamics of PMB are investigated with the aim at ...

We discuss the relation between the deconfining phase transition in gauge theories and the realization of the magnetic Z N symmetry. At low temperature the Z N symmetry is spontaneously broken while above the phase transition it is restored. This is intimately related to the change of behaviour of the spatial 't Hooft loop discussed in [1]. We also point out that the realization of the magnetic...
