to study the effect of strip intercropping pattern with cowpea and soybean on sorghum fodder yield an experiment was conducted at research farm of university of tehran (karaj) during 2005. the experiment was arranged in a randomized complete block design of four replications. the plant proportions included pure culture of sorghum (sss); cowpea (ccc) and soybean (ggg) each in 12 rows; vs differe...

the aim of this study was to assess the effect of several doses of spearmint essential oil (seo; 0, 250, 500, 750 or 1,000 µg ml-1 buffered rumen fluid) on the fermentation kinetic and digestibility using in vitro gas production technique. a total mixed ration (30% roughage: 70% concentrate) was incubated with buffered rumen fluid. in vitro gas production, asymptotic gas production (a), rate of...

the objectives in the cold rolling process include improved sheet surface quality, enhanced steel mechanical strength, and better solidification operations. given the increasing demand for higher steel surface quality, more rapid production, and thinner steel plates, more attention has been directed toward the parameter of temperature in cold rolling as a means of achieving the above objectives...

Leaf-litter assays have advanced understanding of decomposition processes in both terrestrial and aquatic ecosystems. Some shortcomings inherent in the technique may be overcome through use of a cotton-strip assay. Key assumptions for using cotton strips as proxies for natural leaves are: 1) decomposition rates of the 2 materials are related, and 2) the materials decay in a similar way when exp...

Novel arrangements for strip-block designs that reduce the experimental effort are presented. Theoretical properties of strip-block designs using post-fractionation are provided, and appropriate data analysis is explained. An experiment on an industrial process is used as an illustration. As a tool to aid the selection of appropriate plans, catalogs of post-fractionated strip-block designs with...

A new kind of double short strip and single-side micro strip type antenna architecture to develop a frequency reconfigurable annular slot antenna. The design and characterization of this "reconfigurable antenna (RA) annular slot" which was built on a microwave laminate TMM10i Rogers (permittivity=9. 8, loss tangent=0. 002), are presented in this paper. By increasing and decreasing the...

Transfer table is an essential stage between roughing and finishing rolling stands in a hot-strip rolling mill. High temperature and long time that strip is exposed to air at this stage cause a considerable heat loss that accounts for uneven temperature distribution, non-uniform surfaces, reduced product quality and increased production costs. Using thermal shields on the transfer table is cons...

Poorly drained claypan soils can increase the importance of tillage and N management for corn (Zea mays L.) production. Field research in 2008, 2009 and 2010 (high rainfall years) near Novelty, MO (40° 1' N, 92° 11' W) sought to determine the effect of polymer-coated urea (PCU) placement [strip-tillage (ST) deep banded and no-till (NT) broadcast] and application timing (fall, early preplant...

While digital panoramic photography taken along travelling routes is very popular, digital panoramic strip maps are virtually nonexistent. In this article, we explore the characteristics of panoramic strip maps and provide an interactive method for their digital creation, focusing on the challenge of straightening curved routes. The resulting software Terrain Bender implements a geometric defor...
