This thesis focuses on the design and characterisation of miniature bioreactors and evaluates their potential as a scale-down device for microbial cultivation processes. Miniature bioreactors, such as the one detailed in this work, have been developed by many research groups and companies, and seek to increase throughput at the early stages of bioprocess development. Power input was measured in...

contact lens wearers are at great risk of developing microbial keratitis because of incorrect usages and unhygienic maintenance of contact lenses. therefore, the present study was planned to provide data that will be helpful in selecting the anti-microbial to cure microbial keratitis. one hundred bacterial isolates from conjunctiva of contact lenses wearer were isolated, identified and subjecte...

A bipartite graph G is known to be Pfaffian if and only if it does not contain an even subdivision H of K3,3 such that G − V H contains a 1-factor. However a general characterisation of Pfaffian graphs in terms of forbidden subgraphs is currently not known. In this paper we describe a possible approach to the derivation of such a characterisation. We also extend the characterisation for biparti...

In this paper we give a global characterisation of classes of ultradifferentiable functions and corresponding ultradistributions on a compact manifold X. The characterisation is given in terms of the eigenfunction expansion of an elliptic operator on X. This extends the result for analytic functions on compact manifold by Seeley [See69], and the characterisation of Gevrey functions and Gevrey u...

The bacterial community composition of the active layer (0-45 cm) of a permafrost-affected tundra soil was analysed by fluorescence in situ hybridisation (FISH). Arctic tundra soils contain large amounts of organic carbon, accumulated in thick soil layers and are known as a major sink of atmospheric CO(2). These soils are totally frozen throughout the year and only a thin active layer is unfroz...
