        The subject of this article is the elements of creating suspense through rotating narrative in cinema and fiction. Whenever in a literary or dramatic narrative (whether novel, film, etc.) the writer or screenwriter, in addition to the main narrative, brings together several other sub-narratives, the narration is of a rotational type. In simpler language, rotational narrative can be considered as a collection of sub-narratives in the heart of a large narrative whose sharp movement forward in fiction and cinema creates rotational or rotational narratives. In this structure, one of the prominent elements of narrative is the creation of suspense and expectation in several directions, because the audience (viewer) is involved in several incidents. In the home series "Heart" directed by Manouchehr Hadi, through the technique of circular narration, we see several alternating narrations and as a result, the viewer is suspended. Now, in this research, which is provided by a descriptive-analytical method, we intend to analyze the structural elements of the periodic narrative while analyzing its structural elements. The results of the present study show that the periodic narrative is a macro narrative that is a collection of sub-narratives that are created by elements such as flashback, suspension, characterization and descriptive pause.

        In solid state lasers, the light pumping of the laser rod is done by a flash lamp. In order to drive the flash lamp, an electrical power supply consisting of four main parts is used, including the capacitor charging power supply, the trigger circuit, the pulse forming network and the simmer circuit. Using the high voltage output of the trigger circuit, the xenon gas inside the flash lamp is ionized. After the trigger action, the main task of the simmer circuit is to generate a low current in order to maintain the ionized state of the flash lamp. Using the simmer mode increases the life of the flash lamp and also significantly reduces electrical and electromagnetic interference. In this article, a new simmer circuit is proposed for driving flash lamp in solid state laser. The presented circuit has been completely designed and then simulated in the PSPICE software environment. After confirming the correctness of its operation, the proposed circuit has been implemented in a laboratory. Circuit simulation results and laboratory results are presented and reported in this article. Manuscript profile

        Menopause is the important factor in women’s health. Medical progresses indicated women must believe that menopause has not serious danger but some factors such as smoking can be increases premature menopause. In this period social life, feelings and function in women are affected by menopause. Hot flash is the prevalent sign in this period. Usage of ocp can reduce hot flash and other sings such as osteoporosis. This study is a cross-sectional descriptive one accomplished with 329 of the women at the 44-50th of the ages. The sample was selected randomly. The data were collected by a two part questionnaire.the first part included personal and special questions and the second part contained questions about efficacy of the ocp on menopause’s sings. After collecting data they were coded and uploaded to computer for analysis.The SPSS soft-ware was used. In this study 329 subjects were literate 24/9% and 95/5%.were married. Most of them 17/9% were menopausal in the 50th of their ages. 28/3% of them had used ocp and 68/7% had hot flash. There was not any significant relation between usage of ocp and hot flash. Daily taking shower was the only effective factor on the hot flash.Menopause has effected on physical exercise, on the other hand after menopause there was a severe reduction on physical exercise by women.

        The aim of this study, is study on the effects of flash gutter geometry on the material flow, predict of defect formation and forging process parameters in cold forging. For this purpose, effects of three flash geometry with trapezoidal, oval and square shapes were investigated on the simple frustum part. The effect of flash gutter geometry simulated using ABAQUS finite element software and then form with the optimized flash gutter was manufactured and forging process to verify the simulation results on a piece of AA3003aluminum alloy, was carried out. The results showed that trapezoidal flash gutter had more appropriate conditions for material flow than other cases. According to the simulation results, the maximum plastic strain was formed around the flash area and its value was maximum in the die with trapezoidal flash gutter, which was due to the greater flow of the material in the trapezoidal flash gutter geometry. According to the simulation results prediction, the distribution and exerted applied pressure to produce the final part on die with square flash gutter was more than others. The maximum applied pressure was on the flash area of die, which was the largest for the square flash gutter, and had the smallest amount of trapezoidal flash gutter geometry. Manuscript profile

        This study investigated the effect of the readability of the Direct Tax Act on tax risk was examined and a comparison was made between the tax risk prior to and after the amendment of the Act. The data on 37 companies listed on the Tehran Stock Exchange was collected . The results showed that according to the flash method, the chapter on Exemption is the most difficult chapter in terms of readability level and the chapter on the Order of Proceedings is the simplest chapter in the Direct Tax Act. Additionally, the results of the close method for the tax auditors and financial managers were consistent with the results of the flash method. According to the result of the close method for tax auditors, the chapters on Exemption and the Order of Proceedings had intermediate and independent levels of readability respectively. For financial managers, the two chapters had intermediate levels of readability. The results also showed that the readability of the Direct Tax Act had no effect on tax risk. Moreover, the results of the test of the second hypothesis showed that there was no significant difference between tax risk prior to and after the amendment of the Act. Manuscript profile

        در این مقاله، در طراحی فرایند فورجینگ با قالبهای بسته غیر دقیق برای قطعات متقارن محوری، سه پارامتر نسبت عرض به ضخامت پلیسه، نسبت ارتفاع به قطر قطعه کار (بیلت) و فاکتور اصطکاک، با روش اجزا محدود مورد بررسی قرار گرفته است. همچنین دو عامل مهم در فرایند فورج شامل نیروی لازم برای فورج و مقدار پرشدن فضای داخلی قالب بررسی گردید. با کنترل ابعاد پلیسه، امکان کاهش مقدار دور ریز مواد مصرفی و افزایش درصد پرشدن قالب ایجاد می‌شود. برای اعتبار سنجی نتایج این کار تحقیقاتی، مقدار نیروی به‌دست آمده از روش اجزا محدود با مقدار نیروی کار تجربی مقایسه شده است. برای هماهنگ کردن و ارتباط دادن بین پارامترهای مذکور و به‌دست آوردن تابع عملکرد، شبکه عصبی دولایه بکار گرفته شده است. با به­کارگیری تابع به­دست آمده از شبکه عصبی و استفاده از الگوریتم ژنتیک، فاکتور اصطکاک و ابعاد پلیسه و قطعه‌کار برای کاهش مقدار نیرو و افزایش درصد پر شدن قالب به‌دست آمد. سپس، این مقادیر با نتایج کار تجربی مرجع دیگر، مقایسه شده است. الگوریتم ژنتیک تخمین قابل قبولی برای پارامترهای مؤثر در فرایند فورج ارائه کرد، به طوری‌که تطابق و نزدیکی خوبی بین نتایج این الگوریتم و روش تجربی وجود دارد.

        The advent of technology and the internet has fundamentally transformed foreign language acquisition, particularly by enhancing the convenience of vocabulary learning. Consequently, mobile-assisted language learning (MALL) has garnered significant attention as a beneficial resource for language learners. In light of this, the present study aimed to examine the potential impact of utilizing a Mobile-Based Flashcard Application on the vocabulary learning and retention of Iranian EFL learners. This study employed a quasi-experimental design, with participants selected through convenience sampling. The participants were 40 intermediate EFL learners who were selected based on the Oxford Placement Test. Then, the participants were randomly divided into two groups of study namely experimental and control. The participant in the experimental group underwent an eight-session treatment including learning vocabulary based on using the Anki mobile App. In the control group, however, the participants gained new vocabulary by conventional methods. Upon completion of the treatment, an immediate and delayed post-test was administered to evaluate participants' vocabulary learning and retention. The findings of the study indicated that the use of the Anki mobile application led to a significant enhancement in learners' vocabulary acquisition and retention. The findings of this research highlight the potential of educational software, specifically the Anki mobile app, as a valuable tool for English instructors to enhance vocabulary learning.
