BACKGROUND AND OBJECTIVES: Masnavi "Naz va Niyaz" composed by Abdolrazaq Beg Danbali, nicknamed "Fascinated" is a historian, poet, writer, commentator and translator of the literary return period. He composed this poem for the purpose of imitation, with the influence of Khosrow and Shirin Nezami Ganjavi, and the characteristics of the Iraqi style can be seen in it. In the present study, this system has been analyzed stylistically at three levels: linguistic, literary and intellectual. The main question of the research is what are the most important features of Abdul Razzaq's style in Masnavi Naz and Niaz? METHODOLOGY: The method of data collection in this article is based on library studies and research has been done in a descriptive-analytical manner. FINDINGS: Danbali, in accordance with the style of poetry in Persian literature, composed the Masnavi Naz and Niaz and is one of the most eloquent poets of the return period who has succeeded in following the previous poetic styles. CONCLUSION: At the linguistic level, the poet has used the weight of the culprit and high-frequency rhymes and rows of nouns and nouns. At the lexical and syntactic level, the use of prefixes, suffixes and ancient words, Arabic words, various terms can be seen in his poetry. At the literary level, in proportion to the romantic and didactic theme, the use of all kinds of metaphors, metaphors and spiritual novelties has a lot of style and exaggeration. At the intellectual level, in addition to the romantic theme, which is its main subject, he has paid attention to the educational and religious themes and the letter; There is also a belief in popular belief and determinism in his thoughts.

In order to determine the optimal planting model, the multi objective programming was used in Sari Dashte Naz agriculture Company. Also the current model has been compared with two optimal models that one of them is consistent with consumption values and the other is estimated according to the amount of critical consumption of fertilizer and pesticides. The results showed that the current model is different with optimal pattern and it is more appropriate with the environmental and sustainable development objectives.This model not only would increase the gross output to 1230 million Rials but, it is considered as the most appropriate planting model for this region. Therefore, the cropping pattern should be changed and consistence with the self sufficiency objectives of government in production of seeds, the areas under cultivation of canola should be increase and the amount of pesticides and fertilizers usages should be reduced.

Background and Objectives: The development of intensive agriculture has transformed agricultural landscapes into simple, low-coverage single-product systems similar to semi-natural habitats. This trend has led to a sharp decline in biodiversity and a reduction in the provision of ecosystem services to agriculture. It has been confirmed that among ecosystem services, pest and weed control and pollination have significant impacts on global agricultural production. This study aimed to investigate the plant biodiversity of wheat, rapeseed, barley and triticale fields in an agricultural landscape (Dasht-e-Naz Sari). Materials and Methods: This experiment was carried out as unbalanced completely randomized design in an agricultural landscape located in Dasht-e-Naz, Sari (Mazandaran province), during crop year 2019-2020. In this study, 26 farms were selected from different plots of autumn crops (rapeseed, wheat, barley and triticale). Sampling of plant biodiversity was performed based on W pattern with 0. 5 × 0. 5 m2 quadrate. The samples were transferred to the agronomical research laboratory of Gorgan University of Agricultural Sciences and Natural Resources and the flora was determined by genus and species. Then, bidiversity indices including Shannon-Weiner, Margalef, Menhinick, Simpson, Uniformity and Sorenson were calculated using the related equations. In final, based on the results, biodiversity status in the agricultural landscape was analyzed acorrding to status of landscape components including the type patch, corridor, border, etc. Results: In this study, 25 plant species from 14 plant families were identified that 10 species belonged to narrow-leaved and 15 species belonged to broad-leaved. Among the identified species, Rapistrum rugosum L., Avena ludoviciana L., Phalaris minor L. and Cirsium arvense L. were the most abundant. The plant biodiversity in this landscape was in a favorable condition based on Shannon-Weiner index, so that this index for triticale, barley, rapeseed and wheat plots were 2. 64, 2. 52 and 2. 39 and 2. 38, respectively. The amount of Menhinick index for autumn crops of rapeseed, barley, wheat and triticale was as 2. 86, 2. 85, 2. 45 and 2. 32, respectively. Also, the highest Simpson index for rapeseed, barley, wheat and triticale plots was equal 0. 068, 0. 047, 0. 070 and 0. 052, respectively. Based on our results, the highest similarities according to Sorenson index were related to triticale (1), barley (0. 95), wheat (0. 95) and rapeseed (0. 93), respectively. Conclusion: In general, the consumption of manure in some plots, the presence of streams and barren lands in the margins of the plots and corridor of trees as windbreak, could affect on biodiversity of the surveyed landscape. The results of this study can be useful for comprehensive weed management program and making decision about control or improve ecosystem services through plant biodiversity.

The Ghareh naz migmatites were formed as a result of partial melting of amphibolites under granulite facies conditions. Structeral, textural, mineralogical and geochemical evidence in the migmatites migmatites indicates their formation via partial melting during partial melting. The studied migmatites have a variety of structures including patchy, scholen, ophthalmitic, stromatic, diktyonitic, ptygmatic, phlebetic, schliren, pegmatitoid and nebulitic. The presence of striated plagioclases and amorphous quartzes along with granular texture, myrmecite and peritite in the locosome parts as well as the presence of zoning, polysynthetic twin in the plagioclases indicate a partial melting role in the formation of migmatites. Based on mass balance calculations in the ghareh naz migmatites, the parts of the migmatite components of the locosome, melanosome, and mesosome are aligned in a straight line, indicating a partial melting source of the studied migmatites. The percentage of partial melting for the studied megmatites was calculated to be about 36. 5% and 43. 6%, respectively. The difference in partial melting percentages may depend on the relationship between the rate and melt outflow and to a small extent on the amount of melt in the region. The formation temperature of these migmatites is determinated about 850-850 ° C and the pressure is about 6-7 kbar.

“Naz” and “Niaz” are one of the Ghanaian common contents of romantic and mystical ghazals (lyric poems) of Persian literature and poets have used this content in their poems as well as mystics. The basis of relationships in romantic and mystic poets is love. Beloved performs “Naz” and lover is full of feeling of “Niaz”. In all of these relationships, when beloved performs “Naz”, lover accepts it and the sense of need appears in him. The main reason of beloved’s “Naz” lies in her beauty and the source of “Niaz” in lover mostly depends on the “Naz” of beloved. In this paper the joint study of “Naz” and “Niaz” is important especially in poems belonging to Sanai as a mystical poet, Hafez as a romantic-mystical poet, and Vahshi as a romantic poet and writers try to answer these questions: What are romantic “Naz” and “Niaz”? What are mystical “Naz” and “Niaz”? What are the similarities and differences between romantic and mystical “Naz” and “Niaz”? And also different kinds of “Naz” and “Niaz” are contemplated.

In this research, we studied polyamines including putrescine (put), spermidine (spd) and spermine (spm) changes in three common bean (Phaseolus vulgaris) genotypes, K-S-31167, GE-288 and NAZ under drought stress. Our result showed steadily increase in putrescine (put) and spermine (spm) in all three genotypes. GE-288 genotype showed decrease and then increasing in spermidine (spd) content but K-S-31167 and NAZ genotypes showed steadily increasing in spermidine (spd). NAZ genotype accumulated putrescine more than other polyamines and showed the highest amount of putrescine in compare with other genotypes. K-S-31167 genotype accumulated the highest spermine content in compared with other genotypes. Our result showed significant increase in electrolyte leakage (EL) in all three genotypes. K-S-31167 as drought tolerant genotype and ZAZ as drought sensitive genotypes showed the lowest and the highest increase in EL, respectively.

Considering the new concept of emotioncy (emotion+frequency), the present study intends to examine the lingua-cultural concept of [naz] in Persian language using Hymes' (1967) SPEAKING model. The outcomes of this study revealed that the concept of [na] has been mostly prevalent in the collective culture of Iran, and the expressions related to [na] are even more widely used in comparison to the past. The high frequency and variety of this lingua-cultural concept is due to fact that Iranians have mostly positive and mixed emotions toward this concept, and as a result, their level of emotioncy toward [naz] is higher (Inner-emo and Arch-emo).Overall, the results suggest that this lingua-cultural element is more commonly used in informal situations with participants of equal or unequal power relationships. It was also concluded that the main aim behind the use of this lingua-cultural item is to use it as a politeness strategy. Considering the oral mode of language, the tones that are accompanied with [naz] are usually begging, admiring, offensive, and sardonic.

:چکیده A survey of the poems of Naz Al-Malaika and Abdul Wahab Al-Bayati (Sample case study of social incompatibility) Abstract One of the clear and obvious manifestations of new poetry in contemporary Iraq is the phenomenon of social disharmony, this phenomenon emerged in the 20th century with the emergence of Iraqi pioneers such as (Nazak Al-Malaika and Abdul Wahab Al-Bayati, etc.), imitation of the traditional structure, familiarity With the romantic school and the political and social situations of the Iraqi society, these poets became incompatible. They have displayed this literary effect in three ways: literary, political and social inconsistency in their poetry. Their incompatibility in appearance led to the appearance of "Prose Poem" and in the sense of poetry, it caused the awakening and awareness of the Iraqi people and the promotion of the social vision of different social classes. These poets have endured a lot of suffering in creating innovation, such as prison, exile, displacement and alienation, so fear, loneliness, sadness cast a shadow on most of their poems. These poets have been able to express realistic themes and concepts in the form of inconsistency and they are a new spirit in the body of modern poetry. Due to the unfavorable political situation, they used myth and code and repetition style in their poems and were able to transform new poetry so that it can respond to an important part of the concerns of the modern world. Key words: Contemporary Arabic poetry. Social disharmony, "Nazak Al-Malaika", "Abd al-Wahhab Bayati".

Repair and maintenance costs of farm machinery are those expenditures necessary to restore or maintain the technical soundness and reliability of the machine. Accurate prediction of the trend for increasing R&M costs is critical to determine optimum economic life and make appropriate decisions for farm machinery. Hence, a study was conducted to evaluate a cummulative relationship between hours of use and R&M costs for 27 active tractors from two different models in Mazandaran Dasht-e-Naz Farm Company. Required data including annual usage in hours and R&M costs in each year over a ten year period and also tractors initial purchase price were obtained. By regression analysis, mathematical prediction models were evaluated along with their parameters for each individual tractor model and whole sample, separately. In all cases, power function had the best fit and performance among all statistical structures. Results revealed that the amount of R&M costs in the current study are lower than estimated costs in all other previous studies, but relatively higher than estimated costs by the prediction model evaluated by Johann Fuls in a similar survey in South Africa. The reason may be related to lower repair and maintenance wages in Iran, high quality of spare parts used and repair operations and probably good machinery management in the location under study.
