In light of the Bakhtinian heteroglossia and authorial hybrid construction, the present study sets out to argue how the assimilation of alien stylistics into the realm of social and ideological discourse may transcend the limits of the centralizing logos prevalent in the orthodox poetics. In so doing, first, an analysis of the Bakhtinian concepts is provided to renegotiate his argument on the a...

Low-intensity magnetic separators are widely used in the research works and the industry. Advancement in the magnetic separation techniques has led to an expansion in the application of this method in different fields such as enrichment of magnetic mineral, wastewater treatment, and medicine transfer in the human body. In the mineral processing industry, the main application of wet magnetic sep...

since threshing is one of the most sensitive rice post-harvest processing operations, this study was conducted to evaluate the threshing performance in axial - flow paddy thresher. independent variables consisted of: drum speed at five levels (550, 650, 750 and 850 rpm), equivalent to peripheral velocities of: 14.67, 17.35, 20.01 and 22.37 m/s, respectively, paddy moisture content at two levels...

Drum–Buffer–Rope is a theory of constraints production planning methodology that operates by developing a schedule for the system’s first bottleneck. The first bottleneck is the bottleneck with the highest utilization. In the theory of constraints, any job that is not processed at the first bottleneck is referred to as a free good. Free goods do not use capacity at the first bottleneck, so very...

Drum shell bearing edges dictate the boundary conditions and point of contact between drum heads and drum shells. Properties of single 45o, single 45o with slight round-over, and double 45o bearing edges have been studied. It has been found that the double 45o drum allows for the best head/shell energy transfer. I. Background Tom drums are typically composed of a wooden drum shell, a head that ...

We present a live drum separation system for a specific target drumset to be used as a front end in a complete live drum understanding system. Our system decomposes drum note onsets onto spectral drum templates by adapting techniques from non-negative matrix factorization. Multiple templates per drum are computed using a new Gamma mixture model clustering procedure to account for the variety of...

iran, with more than 90% of world production, is known as the main saffron producer. this plant is sterile and the saffron proliferation is possible only via cultivation of corms. one of the most problems in saffron cultivation is the yield reduction due to planting of small corms. in this research, a new saffron corm-grading machine is introduced. the machine includes a rotating drum, which is...

In this investigation, Ti/TiN nanolayer and TiN single layer coatings were coated on substrate of AISI 316L stainless steel by applying physical vapor deposition (PVD) using the type of cathodic arc evaporation (CAE). The evaluation of microstructure were carried out using x-ray diffraction (XRD), nanoindentation, atomic force microscopy (AFM) as well as scanning electron microscopy (SEM). Pola...

a prototype of a straw chopper, equipped with a discharge system was designed and fabricated in the department of mechanics of agricultural machinery, university of tehran, karaj, iran. to test for the effective performance of the machine, the effects of such parameters as: drum speed (at three levels of: 400, 540, and 800 rpm), screen size (at two levels: 2.5 and 4 cm), and number of blades on...
