Postmodernism is a combination of modernism and mythology and is a return to pre-modernism. Moniro Ravanipour is one of the writers who turned to the style of postmodernism and used the elements of this school in some of his works. The purpose of this research is to know the characteristics of this school in the works of this author.

In this research, based on post-modern characteristics and descriptive-analytical method, the works of Moniro Ravanipour were investigated.

In these works, with the use of elements such as: the involvement of the narrator in the story, criticism of the story in the story itself, changing the direction of the story, using fantasy characters, changing the roles of characters, uncertainty, symbolism and intertextuality, the postmodern style emerged as metafiction. By creating postmodern works, the author tried to convey his point of view to the audience in an indirect way.

Postmodernism has become a platform for the expression of the author's opinions in the form of novels and stories and has provided the possibility to create different voices in the story.

Improving sustainability in supply chains is one of the strategic objectives in the current business. The purpose of this paper is to provide a model for assessing the sustainability performance of LARG supply chain management practices in the automotive supply chain using the dynamics system. In this paper, LARG supply chain management practices were identified and were prioritized using fuzzy DEMATEL and fuzzy analysis network process.

  Dorfak (Line No.424) is a single cross derivative between Sepidrood, a high yielding improved rice cultivar used as male parent and Salari, a traditional landrace with premium cooking quality and poor in yield as female parent. The cross was attempted in 1988 and the F2 generation onwards of the cross was raised in the pedigree breeding approach. The F2 single plant selections were based on early, synchronous flowering habit, increased number of tillers, high yielding potentials with reduced plant height and resistance to blast disease. However, the selections based on grain quality were initiated from F5 generation (1994) onwards. Amongst the different selected pedigree families of the selections made earlier, the line 424 was identified as high–yielding, semi-dwarf, resistant to blast and possessing good cooking quality characteristics in 1995. This selected line was entered into preliminary yield trials and advance yield trials in comparison to improved cultivars like Khazar and Sepidrood. Multi-environmental trials were conducted at three sites over 3 years (1996-98) and the pooled analysis of these trials averaged over sites and years, revealed highly significant differences (P 1) for yield. The line 424 performed consistently, yielding in the range of 5.5 to 6.3 tha-1 with an yield advantage of 17.4% over improved cultivars like Khazar while 34.5% over traditional check cultivar Binam in three on-farm trial sites. The selected line 424 was named as Dorfak and was released for cultivation in Guilan province in 2002. Dorfak is a semidwarf (plant height 110 cm), aromatic, short duration cultivar (120 days) with 17 productive tillers, 115 grains per panicle, good grain and cooking quality features. Rice kernel characteristics clearly showed that line 424 was a highly transgressive in nature especially for kernel length and length/width ratio. However, for all other grain quality traits, Dorfak was much closer to the traditional landrace parent i.e. Salari. Dorfak, was released in 2002 for cultivation, to a large extent combined the premium cooking quality features of the traditional landraces and the yield of improved cultivars, hence becoming popular with the farmers and consumers alike.   Â

Systemic properties of pyroquilon, an anti-blast systemic chemical, used in controlling rice blast disease caused by Pyricularica grisea, was investigated through in vivo tests. Rice plants were treated with pyroquilon as granules in soil. Leaf and stem tissues were collected at different times after treatment and pyroquilon was extracted from tissues and detected by gas chromatography. Treated rice plants were also exposed to disease infection in blast nursery at different times and disease incidence was evaluated one week later. Pyroquilon was detected in leaf tissue one day after treatment (DAT), reached maximum during 4-7 DAT, and then reduced gradually to a nondetectable level after 28 DAT. In stem tissue, change in pyroquilon content was similar to but its quantity was less than that of leaf tissue. On inoculated plants, disease was controlled up to 60% at 2 DAT and completely controlled during 4-28 DAT. The results indicated that pyroquilon could be taken up and systemically translocated in rice plants after applying as granules in soil. Extent of disease control was a good function of pyroquilon content in leaf tissue (R2=0.93) and 2 ppm of compound in leaf could provide 90% control of the disease. In contrast, disease control was not a good function of pyroquilon content in stem tissue (R2=0.30).
