Najmuddin Mohammad Falaki Shervani is one of the poets of the sixth century AH and the poet of the court of Manouchehr ibn Fereydoun Shervanshah. biographers have written the number of verses of the falaki's Divan from five thousand verses to fourteen thousand verses; But what is left of his poems does not reach two thousand verses. Research and search in the falaki's Divan and the manuscripts of his divan, shows the fusion of some poets' poetry with Falaki Shervani's poems. In this research, after studying and carefully examining the Divan of Falaki and its manuscripts and searching in the Divan of poets of the fifth to seventh centuries AH and the wars and manuscripts of their poems, the poetry of some poets, such as: Asjadi, Masoud Saad Salman, Qatran Tabrizi, Adib Saber Termedhi, Majd Hamgar and Jalaluddin Mohammad Molavi, we found out that either his poems were recorded in the Falaki printed Divan and its manuscripts, or Falaki poetry was published in their Divan. In this research, these poems have been studied and their true poet has been determined, In order to provide a complete correction from the divan of the mentioned poets, than this be the helper of the proofreaders as well as the researchers of theyr poems.

One of the issues which domestic and foreign scholars have done a lot of research surrounding, in recent century, is Persian national narrations and epic stories. About this topic, European researchers and other international experts on the subject of Iranian scholars conducted valuable researches. Zabih ‘Allah Safa. By writing the book “Epic Poetry in Iran” could open the way for Iranian researchers in this field and prepared an important resource for those interested in the study of Persian Epic Literature. This book, which is one of the major sources for PhD Persian literature students and also for researches in national narratives, in some cases need to be edited and corrected; So this research is about criticizing it both in the way of writing and in its content to be removed from ambiguity and redundancy. This research is considering; spelling errors and punctuations, Arabic unfamiliar words, ambiguities and contractions in some subjects, the mismatch of the text by its source, general discussion in some issues that need to be corrected and spoke about some matters which need to explain further.

The concept of jus cogens entered into international law through the law of treaties and today has become one of the most important and effective rules of international law. The principal and recognized function of the jus cogens is to invalidate any treaty which is in conflict with it. Some States resort to unilateral acts to achieve their goals and to avoid the limitations imposed by the  jus cogens, because given the lacuna in international law, they consider those acts to be outside the influence of the jus cogens. In recent years, we have seen the functional development of the jus cogens in areas other than the law of treaties. This article, examines the function of jus cogens in the field of unilateral acts of States, to determine if unilateral acts of States, where they conflict with a peremptory norm, produce any legal consequences, and if the jus cogens has any impact on such acts, is its function in the field of unilateral acts similar to that of the law of treaties or does it has a different function.

 One of the valuable literary activities in the contemporary era is correcting the texts left by the predecessors. The Divan of Shervani, the poet of the sixth century (AD 540), is one of the texts from which has not yet received a proper revision.This is mainly because of the unavailability of a reliable manuscript, collected during or close to the poet's era. In addition, those who have attemplted to correct the available manuscripts, have not observed the proper critical methods of text correction. The existing version corrected by Taheri Shahab in 1345 AH suffers numerous methodological and typographical defects. In this study, while showing the main correction defects of the existing version, such as "improper recordings", "displacement of verses", "scattered poem lines " and "typographical errors", it tends to introduce the new versions and explain their role in correcting the poems of Shervani. The poems of this poet are discussed in order to highlight the necessity of re-correcting the Divan of  Falaki Shirvani, which, in addition to presenting a revised text of his poems, undoubtedly has a great impact on recognizing the stylistic features of Azerbaijani poetry and solving some problems of poems following this school .

Zinc has a role in many cases such as rumen microbial activity, immunity, and blood metabolites. But, there is no sufficient information on the effect of nano and organic Zn supplements on microbial protein synthesis and immunity variables in Holstein calves. Thus, this study was conducted to assess the effect of using nano-ZnO and Zn-methionine instead of ZnO (equal to or twice NRC 2001-recommended level) on urinary purine derivatives, microbial protein, immunoglobulins and nitrogenous compounds of the blood in pre- and post-weaning calves.

Sixty suckling Holstein calves were assigned into one of the 6 experimental groups (10 replications) in a completely randomized design. The experimental treatments were the diets containing: 1- ZnO equal to NRC recommendation, 2- Zn-methionine equal to NRC recommendation, 3- nano-ZnO equal to NRC recommendation, 4- ZnO twice NRC recommendation, 5- Zn-methionine twice NRC recommendation, and 6- nano-ZnO twice NRC recommendation. During 7 to 30 days of age, the calves were fed with milk and starter concentrate according to the above treatments. From days 31 to 70, milk and mixed alfalfa-starter (at the ratio of 10:90) were provided for the calves. Weaning was done at 70 days of age and during post-weaning period (71 to 100 days of age), the calves were freely fed with experimental diets (alfalfa and starter concentrate at the ratio of 20:80). During pre- and post-weaning periods, the urinary purine derivatives, microbial N synthesis, total globulin, IgM, IgG, total protein, albumin, urea-N, creatinine and glucose of the blood were determined. Data were analyzed in a factorial experiment (3×2) using PROC MIXED of SAS (2001).

Urinary purine derivatives and microbial N synthesis were not affected by replacing ZnO with nano-ZnO and Zn-methionine during pre- and post-weaning periods. Zinc chemical form had no significant effect on the blood concentrations of total globulin, IgM and IgA. Total protein, albumin, urea-N, creatinine and glucose in the blood of the calves fed with inorganic, nano or organic Zn supplements were the same. Moreover, increasing Zn level in the diet had no effect on urinary purine derivatives, microbial N synthesis, total globulin, IgM, IgA, total protein, urea-N, creatinine and glucose.

Using nano-ZnO and Zn-methionine instead of ZnO and also the increasing dietary Zn level had no effect on microbial protein synthesis, IgM, IgA, nitrogenous compounds and glucose in the blood of the calves. Thus, feeding the conventional inorganic Zn source (ZnO) at the NRC-recommended level was sufficient to supply the calves’ requirement during pre- and post-weaning periods and the other sources are not recommended.

One of the varieties of oral literature is the song. The songs in the Bakhtiari culture and literature are widely used. Language as a part of human society has a significant role in the forming of the customs and culture of every nation and community. The role of women in the lyric poetry is very significant and chief. In this research, we investigate the role and position of woman in oral literature especially Bakhtiyar's songs. In this regard, the songs were divided into eight categories. Subsequently, the role of women and the analysis of songs on the determination of women's role have been studied. Then, we find that the Bakhtiari woman, in many cases, is a self-constructor, speaker, and designer in relation to songs, and used them in most stages of their lives and everyday tasks. Some sample of songs are about the women but not created by them.

This paper presents a bi-objective MIP model for the flexible flow shop scheduling problem (FFSP) in which the total weighted tardiness and the energy consumption are minimized simultaneously. In addition to considering unrelated machines at each stage, the set-up times are supposed to be sequence- and machine-dependent, and it is assumed that jobs have different release times. Two Taguchi-based-tuned algorithms: (i) non-dominated sorting genetic algorithm II (NSGA-II), and (ii) non-dominated ranked genetic algorithm (NRGA) are applied to solve themodel. Six numerical examples with different sizes (small, medium, and large) are used to demonstrate the applicability and to exhibit the efficacy of the algorithms. The results show that the NRGA outperforms significantly the NSGA-II in the performance metrics for all six numerical examples.

The objective of this study was to assess the effect of new bonding techniques on enamel surface. Sixty upper central incisors were randomly divided into two equal groups. In the first group, metal brackets were bonded using Trans-bondXT and, in the second group, the same brackets were bonded with Maxcem Elite. The shear bond strength (SBS) of both agents to enamel was measured and the number and length of enamel cracks before bonding, after debonding and after polishing were compared. The number of visible cracks and the adhesive remnant index (ARI) scores in each group were also measured. There were significantly more enamel cracks in the Transbond XT group after debonding and polishing compared to the Maxcem Elite group. There was no significant difference in the length of enamel cracks between the two groups; but, in each group, a significant increase in the length of enamel cracks was noticeable after debonding. Polishing did not cause any statistically significant change in crack length. The SBS of Maxcem Elite was significantly lower than that of Transbond XT (95% confidence interval). Maxcem Elite offers clinically acceptable bond strength and can thus be used as a routine adhesive for orthodontic purposes since it is less likely to damage the enamel.

The routine treatment for rotated maxillary incisor is a fi xed appliance, but in some instance the use of this method is impossible. In addition, in only limited cases of rotation, removable appliance is applicable. In this study, the use of a semi-removable appliance is presented, which has some benefi ts over the other methods. In this study, the corrections of about 70 -90° rotation of the maxillary central incisors in different phases of mixed dentition were performed in three patients using whip appliance. This method was performed using a simple removable appliance such as Hawley appliance and whip spring that forced the couple to derotate the tooth. In all cases, treatment was successfully completed in relative short duration. Whip appliance can be recommended as an effective method to correct rotation of maxillary incisor in mixed dentition with several advantages like rapid correction.
