this study was conducted to determine the effects of different water and nitrogen application levels on drip-irrigated tomato plants. the amount of water usage was based upon the pan evaporation from a screened (class “a”) evaporation pan. the treatments consisted of two irrigation intervals (i1= 5 days and i2= 10 days), three plant-pan coefficients (kcp1= 0.50; kcp2= 0.75 and kcp3= 1.00) and t...

The sales figures of antimicrobial (AM) drugs for farmed Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) in Norwegian aquaculture was high, although varying, in the period 1981-1994. Since then the usage in these species has been negligible in spite of the huge increase in the biomass fish produced. This is mainly due to the introduction of efficient vaccines against the m...

Recently, language resources (LRs) are becoming indispensable for linguistic researches. However, existing LRs are often not fully utilized because their variety of usage is not well known, indicating that their intrinsic value is not recognized very well either. Regarding this issue, lists of usage information might improve LR searches and lead to their efficient use. In this research, therefo...

A cake is a metaphor for a heterogeneous, divisible good, such as land. A perfect division of cake is efficient (also called Pareto-optimal), envyfree, and equitable. We give an example of a cake in which it is impossible to divide it among three players such that these three properties are satisfied, however many cuts are made. It turns out that two of the three properties can be satisfied by ...

Fair Division, unlike most research on fairness in the social sciences and mathematics, is devoted solely to the analysis of constructive procedures for actually dividing things up and resolving disputes, including...
