The influence on ammonia emission to the atmosphere, of five types of slatted floor and of
the degree of fouling of the solid floor was investigated in houses for fattening pigs. In the …

Bij het meten van ammoniak emissies is veel gebruikt gemaakt van een in 1993 verschenen

To improve the slip resistance of solid floors in dairy cow houses and to achieve the ammonia
emission reduction prescribed by the Dutch government, precast concrete floors with …

Two methods to reduce the ammonia emission from double-sloped solid floors, with a gutter

We demonstrate the calculational style of program development. In doing so we introduce
virtual data structures which play the rôle of a catalyst in the development of programs, in the …

The relation between surface characteristics and urease activity was studied for samples (300×300

Higher Order Attribute Grammars (HAGs) are an extension of normal attribute grammars in
the sense that the distinction between the domain of parse-trees and the domain of attributes …

This paper presents a new strict, purely functional implementation of attribute grammars.
Incremental evaluation is obtained via standard function memoization. Our new implementation …
