This paper discusses the semantics of the prialt construct in HandelC[1]. The language is essentially a static subset of C, augmented with a parallel construct and channel communication, as found in CSP. All assignments and channel communication events take one clock cycle, with all updates synchronised with the clock edge marking the cycle end. The behaviour of prialt in Handel-C is similar in...

Field experiments were conducted to study weed population shifts in long-term conservation tillage systems. The objectives of this study were to determine weed community abundance, diversity and composition on conventional tillage (CT), minimum tillage (MT), no-tillage with paraplow (ZT) and no-tillage (NT) systems, and to identify species that are associated with specific tillage systems. The ...
