Zooplankton of Bohemian Forest lakes as indicator of recovery from acidity
Kohout, Leoš ; Fott, Jan (advisor) ; Macháček, Jiří (referee) ; Bitušík, Peter (referee)
CONCLUSIONS In my Ph.D. thesisthe ťollowingitems arediscussed It is hypothesisedthat Al govems the P availability in the acidified lakes, as well as shapesthe foodweb structure. Substantialportion of the plankton biomass in the Bohemian Forest lakes is createdby hetelotrophic fi|amentswhen filtering cladocerans aÍenot present (theyareextinctor occuÍseasonal1y). After ťrrstsigns in the nineties further evidence for the ongoing biological recovery was collected. Nevertheless, the lakes are still stongly or partially influenced by acidification and standardfood web relationshipshave not been restored. The significant hysteresisof biological recovery behind the reversal of lake chemistryin theBohemianForest and elsewherecould have severalreasons: - Isolationofremote headwaterlakes makestheprocessofzooplankton re- colonizationstochastic,theprobability being atleastfor somecnrstacean specieslow.

Integrální návrh v architektuře
Kohout, Lukáš
Integrated design is an approach to design that incorporates specialism in different fields that are usually considered as separate professions. Integrated design brings together methods that support specialists from different fields of design and construction. Due to the cooperation between architects, engineers, owners and users established during this process, significant cost and resources reduction in construction is achieved. Described cooperation can be often found in large architectural businesses –we can find SIAL or GAMA in Czech Republic (more specifically in Czechoslovakia); MVRDV, Behnish Architekten and Transsolar in foreign countries.

Architectures of Digital Self-adaptive Systems
Kohout, Lukáš
The article concerns with a self-adaptation in digital circuits. The text includes the definition of the the SANE concept which directly uses the principles of the self-adaptation, a basic description of the SVP model which provides a computing representation in the SANE. In the text is a basic description of the UTIA HW platform (the SANE implementation) which was complemented with a job scheduler. The experiments with the job scheduler was described.
