Shortage and salinity of irrigation water are two major constraints that influence rapeseed production in arid and semi-arid regions of central and southern Iran. In this study, effects of deficit irrigation with different salinity levels and planting methods (in-furrow and on-ridge) as strategies for coping with water and salinity stresses on yield and yield quality of rapeseed were invest...

in the near future, design of a new generation of drugs targeting proteins will be required. considering the complex bond between the drug and protein, the structure and stability of the target protein should be considered. so far, a series of in vitro investigations have been conducted with the aim of predicting drug-biological medium interactions. in these studies, use of spectroscopic method...

Introduction The co-digestion of manure with other substrates such as energy crops, industrial wastes, or food industry wastes enhances biogas production. The addition of co-substrates to manure can improve the carbon to nitrogen balance which results in a stable and maintainable digestion process [1]. Co-digestion also improves the flow qualities of the co-digested substrates [2]. Perhaps the ...

The World Summit on Sustainable Development (Johannesburg, 2002) encouraged the application of the ecosystem approach by 2010. However, at the same Summit, the signatory States undertook to restore and exploit their stocks at maximum sustainable yield (MSY), a concept and practice without ecosystemic dimension, since MSY is computed species by species, on the basis of a monospecific model. Ackn...

Prediction of lactation yields and accuracies of yields for use in genetic evaluation can be improved by including information from test day correlations, especially for milk recording plans that vary in the numbers of milk weights recorded and component samples taken. Daily milk weights for 658 lactations of Canadian cows and monthly test records of milk, fat, and protein yields and somatic ce...

Persistency of lactation is the ability of a cow to continue producing milk at a high level after the peak of her lactation. Differences in persistency, if not properly accounted for, reduce accuracy of genetic evaluation when incomplete records are used. Persistency has also direct economic value. Reduction of feed, health and reproductive costs are the major factors which favour more persiste...

In this paper we prove that the reliability of the classifications of individual instances, provided by a classifier, results in information gain with respect to the accuracy of the classifier. We illustrate this result using our new approach to classification reliability called version space support vector machines.
