the purpose of this research is investigation of application of the arbitrage pricing theory and effect of unanticipated changes in a set of macroeconomic variables such as inflation rate, money supply, exchange rate, oil price, term structure and industrial production on expected security return in tehran stock exchange. in this research, data are analyzed quarterly for the period of 1997-2008...

Today, industrial production lines commonly use off-line and automatic on-line quality monitoring and control. Monitoring and control units analyse data from a production process, and analysis should be able to obtain reliable information that correspond with the character of the data obtained. The character of the data set obtained from production processes or from products can be highly struc...

Soybean (Glycine max (L) Merr.) seed treatments are recognized as useful in reducing losses from seed borne pathogens and seedling damping off agents. The seed treatment with fungicide is essential in the improved technology for increasing crop production. In the present investigation two seed protectant fungicides captan and carbendazim are used. Effect of fungicides on growth of Rhizobium jap...

With the emphasis on reducing costs and increasing efficiency, a record number of companies are embarking on different forms of advance manufacturing technologies (AMT). AMT are broadly defined by many authors (small and chen, Sheppard and stock) as “ an automated production system of people, machines and tools for the planning and control of the production process, including the procurement of...

For the 5-year period 1991 to 1995, 1536 vegetable and 802 fruit samples were analyzed. The purpose of this study was to determine if pesticides were present on Ontario-produced fruits and vegetables, and if so, to determine if residues violated maximum residue limits (MRLs). Overall, 31.5% of the samples had no detectable pesticide residues, whereas 68.5% contained one or more residues. Most o...

Efficient production systems are necessary for the realization of products that fulfil customer needs and delivery requirements. Generally, the task of designing production systems belongs to the Production Engineering field. The system design work is, therefore, often managed and performed by production engineers at manufacturing plants with the support of relevant expertise from other discipl...
