چکیده

The relationships between agricultural science, invention, production and consumption are conventionally considered in a hierarchical model with consumption at the basis and science at the pinnacle of the hierarchy. Two important shortcomings of that model as a basis for organizing and managing agricultural research are identified. First, the model does not specify how the direction and intensity of research is guided in the absence of markets for the outputs from research. Second, the model does not identify the flows of specific information from the consumption and agricultural production sphere to the research sphere where such information is crucial for the successful conduct of applied agricultural research. An alternative conceptual framework for agricultural research is explored that considers research as a problem-solving activity which exploits general scientific knowledge as well as specific practical knowledge. Implications of a problem solving perspective for the organization and management of agricultural research are discussed.

Effects of Replacing Alfalfa Hay and Wheat Straw by Pistachio by-Product Silage and Date Waste on the Performance and Blood Parameters of Fattening Lambs

In this trial effects of feeding pistachio by-product silage with date waste (PBSD) on dry matter intake (DMI), live weight gain and blood parameters of lambs were studied. Ensiling of pistachio by-products (PBP) with date waste increased dry matter (DM) and metabolizable energy (ME), but decreased the percentages of crude protein (CP), total tannins and phenolic compounds (P

A new heuristic approach to solve product mix problems in a multi-bottleneck system

Product mix problem (PMP) is one of the most important and complicated problems in production systems. Different approaches have been applied to solve this problem, among them, theory of constraints (TOC) has been widely considered since 1990s. This paper develops a distinguished algorithm to solve product mix prob-lems that is efficient both in single and multi-bottleneck problems. At first, t...
