Affinities of the fern genus Ptisana (Marattiaceae) in the Solomon Islands, with descriptions of two new species

In the process of undertaking a comprehensive review of the pteridophytes of the Solomon Islands, multiple unidentified specimens of the fern genus Ptisana Murdock (Marattiaceae) were collected.Morphological and molecular chorulon hcg phylogenetic analyses as well as field observations were required to identify the Solomon Islands taxa.Four species

An agent-based modelling framework for the simulation of large-scale consumer participation in electricity market ecosystems

Abstract The role of consumers as price-sensitive participants in electricity markets is considered essential to ensure efficient and secure operations of electricity systems.Yet the uncertain or unknown consequences of active market participation remain a large barrier for active consumer-side market participation.Simulations are a powerful tool t

Susceptibility of pancreatic beta cells to fatty acids is regulated by LXR/PPARalpha-dependent stearoyl-coenzyme A desaturase.

Chronically elevated levels of fatty acids-FA can cause beta cell death in vitro.Beta cells vary in their individual susceptibility to FA-toxicity.Rat beta cells were previously shown to better resist FA-toxicity in conditions that increased triglyceride formation or mitochondrial and peroxisomal FA-oxidation, possibly reducing cytoplasmic levels o

Clustering of hotspots in the cosmic microwave background

The physics behind the origin and composition of the Cosmic Microwave Background (CMB) is a well-established topic in the field of Cosmology.Literature on CMB anisotropies reveal consistency with Gaussianity [1], but these were conducted on full multi-frequency temperature maps.In this thesis, we utilise clustering algorithms to specifically conduc
