Effects of pea aphid secondary endosymbionts on aphid resistance and development of the aphid parasitoid Aphidius ervi: a correlative study

In order to reduce parasite-induced mortality, hosts may be involved in mutualistic interactions in which the partner contributes to resistance against the parasite. The pea aphid, Acyrthosiphon pisum Harris (Hemiptera: Aphididae), harbours secondary bacterial endosymbionts, some of which have been reported to confer resistance against aphid parasitoids. Although this resistance often results in d

Evaluation of stator and rotor lamination materials for thermal management of a PMaSRM

In this paper, the thermal impact of using different steel laminations in the stator and the rotor of a permanentmagnet assisted synchronous reluctance machine designed for an automotive application is studied. In this regard, two main parameters of the steel lamination materials, thickness and amount of alloy content in weight percent, are studied. Frequency characteristics of the iron losses of

On the problem of placing Mobility Anchor Points in Wireless Mesh Networks

Over the past few years, wireless mesh networks are emerging as a strong technology for cheap wireless coverage. Despite recent advances in wireless mesh networking, many research challenges remain in all protocol layers. Since a mesh network usually has very different characteristics than those of current fixed mobile networks, traditional fixed deployments such as those in cellular IP and HMIP w

Simulation of Chemical Reactors

This thesis consists basically of two parts. They are, however, interrelated by the fact that both parts concerns modelling of catalytic reaction systems and also by the fact that in both parts, spectral methods are used for simulation. The first part describes the numerical treatment of the dispersion model. The model is used to simulate a packed-bed reactor producing formaldehyde from methanol w
