Plant-herbivore interactions are influenced by host plant quality which in turn is affected by plant growth conditions. Competition is the major biotic and nutrient availability a major abiotic component of a plant's growth environment. Yet, surprisingly few studies have investigated impacts of competition and nutrient availability on herbivore performance and reciprocal herbivore effects on pl...

A new approach to robust performance problems is proposed in this paper. Theapproach involves the optimisation of so-called performance weights subject to aconstraint, formulated in terms of the structured singular value, which ensures theexistence of a stabilising feedback compensator that achieves robust performancewith respect to the optimised performance weights and an u...

While plant diversity is well known to increase primary productivity, whether these bottom-up effects are enhanced by reciprocal top-down effects from the third trophic level is unknown. We studied whether pine tree species diversity, aphid-tending ants and their interaction determined plant performance and arthropod community structure. Plant diversity had a positive effect on aphids, but only...

This study aimed to determine plant performance and added value of soybean farming by applying tillage spacing. was conducted two treatments, namely treatment I: no-tillage scatter planting system on farming, II: spacing farming. Primary data were in the form performance, production, The analyzed descriptively using average growth productivity, RCR, BCR, MBCR. results showed that with resulted ...

Municipal solid waste combustion (MSWC) plant operators are currently under an increasing pressure to optimize the economic performance of their plants. A route with high potential for optimizing this performance is by improving the performance of the MSWC plant combustion control system, which typically is of the PID-type. In this paper, motivated by the industrial need to improve the overall ...
