Heat production, energy and nitrogen balances of artificially reared piglets from specific pathogen free sows, housed in a respiratory chamber, were measured over five successive periods of 7 days each from 4 to 39 days of age. The experiment was carried out at an environmental temperature decreasing from 33 to 27°C. The mean weight increased from ...
Hydrogen can be produced by a number of processes, ranging from water electrolysis by means of electrical energy to photobiological hydrogen generation by means of solar energy with the aid of autotrophic organisms. In the latter case, a closed hydrogen cycle might be harnessed. Whether industrial-scale hydrogen generation and harnessing of hydroge...
The overall objectives of the EC Research Programme JOULE II were to evaluate the potential of advanced power production systems based on biomass gasification and to study the technical and economic feasibility of these new processes with different types of biomass feedstocks. This report was prepared as part of a larger R & D project within JOULE ...
In this paper a revised version of Lettau's evapoclimatonomy model is used to simulate climate in West Africa. The model is applied specifically to the study sites of the HAPEX-Sahel region in Niger, an international regional experiment to study regional-scale hydrological and energy balances of the Sahel. The model uses monthly means of precipitat...
This book describes an analysis of processes and factors that affect the energy balance of bare soil, and the associated exchange of heat and moisture at the surface. After a brief treatment of basic transport theory, the processes of soil-atmosphere interaction are expressed in a simulation algorithm. This algorithm provides an instrument to study...
Strategies for thermochemical processes is made, i.e. pinch analysis and exergy analysis. Although both methods have a unique root, i.e. the minimization of the exergy losses, pinch analysis has evolved to become an instrument of direct and optimal design of a heat exchanger network while exergy analysis as such does not give an indication about pr...
Enkele leden van het projectteam geven in dit artikel ook praktische problemen bij de uitvoering van het BIM-systeem aan, die mede aanleiding zijn tot een vervolgproject.
