Abstract
The similarity between myth and story has brought about theories based on which recurring elements between myths and stories can be explored and analyzed. This research, borrowing a descriptive-analytical method and following the theoretical framework of Carol S. Pearson and Hugh K. Marr Psychological -archetypal analysis in "Awakening of the hero within", and Joseph Campbell's The “Hero's Journey” theory, tries to examine the process of the "hero within" journey in the story of Bahram and Golandam. The study tries to analyze the manifestation quality of archetypes throughout the journey to show that the hero of the folk stories, like the sages, can step into the process of individualism and starts the heroic journey via the manifestation of these archetypes. Analyzing the mythical structure of this story, it turned out that the story consists of three stages of “departure”, “initiation” and “returning” which pave the way for the advent of the archetypes. The hero starts the journey by leaving home, and then the explorer archetype begins. Throughout the journey, according to fictional situations, the inner hero archetype faces metamorphosis and other archetypes arise consequently. The most vivid archetypes of Bahram are “lover”, “explorer” and “warrior” when the end comes by forming a family which shows the "returning" stage to the home environment where the “ruler” archetype occurs.  The results of this study show that the story of Bahram and Golandam has a mythical structure, and can be analyzed on the basis of the archetypes theories, due to its psychological approach.
 

Keywords: Folk literature; mythical structure; hero within journey; Bahram and Golandam; children's literature.
 
Background
In context of hero within journey and the manifestation of archetypes, remarkable studies have been done such as Sarmadi et al. (2014) in which they the studied hero within archetypes in the novel Shazdeh Ehtejab. In another case, Ghasemzadeh (2014) analyzed the characters of Kaykhosro and Siavash in Shahnameh based on Pearson- K. Marr theory. Lastly, Ghasemzadeh (2013; 2016) studied the Little Black Fish and Bi-o-Tan stories based on the same theory.
The story of Bahram and Golandam has been studied from different aspects. In one study, Zolfaghari and Arastoo (2008) studied the themes in Bahram and Golandam, and Mashhadi and Dastan (2014) analyzed the narrative structure of Bahram and Golandam story on the basis of Greimas theory. Nevertheless, considering these stories from the psychological-archetypical aspect leads to more precise perception of society, culture and history of children literature.
Aims, Questions, and assumptions
Reading, revising and studying of stories can be done through archetypes analysis theories in order to reach a collective unconscious interpretation. Zolfaghari (2015) believes that studying folk decorum in one way relates to anthropology, and on other hand, relates to literature. The goal and necessity of reading and studying Bahram and Golandam story, on basis of hero within journey theory, is linked to the perception and cognition of collective unconscious and the spirit of stories society. This becomes increasingly evident in the case of Bahram and Golandam story which is classified as a part of the Iranian folk literature and also a readable resource for children and teenagers in the Qajar era and even before.
This study attempts to find the answers to the following questions: What are the courses of archetypes development and the process of their emergence in the story of Bahram and Golandam? What are the main archetypes in this journey? What are the effective factors in hero’s evolution and growth? How the hero’s image would be criticized on the basis of the archetypes criticism method?
Discussion
The hero in the journey within will experience three stages of departure, initiation, and return (Campbell, 2010). After passing these stages, 12 archetypes with unique traits will appear within the hero. He would gradually experience these archetypes and returns with power and strength at the end which is all due to the experience of self-knowledge and exploration. (Pearson- K. Marr, 2011) the study of hero within journey process and the acts of Bahram, as the manifestations of each archetype, shows that the lover, explorer, warrior and wizard archetypes are most frequent in Bahram's heroic journey. This begins with the explorer and innocent archetypes at the departure stage. Explorer archetype is repeated throughout the journey and the innocent archetype is removed after the initial steps. In the initiation stage, in order to reach the goal (i.e. joining the beloved – the meaning), the hero denies his identity and chooses anonymity consciously. Since Bahram and Golandam story is classified as love stories, the repetition of lover archetype is realized in Bahram’s character. In addition to the lover archetype, there are three dominant archetypes in Bahram’s heroic journey: the explorer, warrior, and wizard. Wherever no power and strength remains, he calls for the supernatural powers.
Conclusion
Bahram and Golandam folk story basically stands on the mythical structure. In this regard, Joseph Campbell's theory can be an appropriate means of investigation for this story. According to Pearson- K. Marr theory, Bahram can be respectively the Icons of lover, explorer, warrior, and wizard archetypes, and Golandam is the allegory of the hidden half of existence, a mysterious journey for discovery and cognition. Lastly, China is the code of true world. It seems that real maturity is gained by finding the hidden half of the existence, and Bahram, passing the stages of his journey, reaches the true destination of discovering his half (i.e. joining Golandam). He finishes his heroic journey and returns home like the king of two worlds. As mentioned earlier, Bahram and Golandam story is classified as a folk literature and children literature history, thus, considering Bahram as a hero in the mind of children and young people shows that the four explorer, lover, warrior, and wizard archetypes are attractive and acceptable among them.

Abstract

Biosurfactants are produced by microorganisms. Surfactin is one of the main lipopeptide biosurfactants produced by different species of Bacillus subtilis. This study aims to analyze the effect of starch-coated Fe0and Fe3+nanoparticles on the biosurfactant production of Bacillus subtilis. Out of 70 soil samples, 20 Bacillus were isolated and genome sequenced by biochemical methods and 16S rRNA gene. Quantitative and qualitative screening methods were used to isolate and detect biosurfactant production. For the aim of this study, 61 and 63 (Bacillus subtilis subsp. Inaquosorum) were selected. Then, hemolytic activity, surfactant production and reduction of surface tension in Minimal Salt Medium containing Fe0 and Fe3+ nanoparticles were examined after 48h, 72h and 96h of culture. The binding of the nanoparticles to the surfactant was confirmed by SEM. Strain 61 was the best bacterium and Fe3+ was the best nanoparticle and it was cultured. The results were compared with the results of non-nanoparticle bioreactor. Surfactin from strain 61 culture in the Fe3+ nanoparticle bioreactor after 72 hours of growth showed higher production than the same strain culture after 72 hours without Fe3+, if continuing the research, this strain can be commercialized in the future.

Abstract

Nowadays, laser 3D printers are one of the efficient devices for rapid prototyping process. There is vast number of studies about quality of samples in these printers. The laser sintering technique is the one of the popular method for consolidation and shaping of semi-crystalline polymer powders. In this study, we considered the role of laser parameters included laser scanning pattern, laser scanning speed and power in tensile strength and stiffness as the important factors of the mechanical property of samples which are sintered by laser in single layer procedure. Experimental samples were sintered with low power CO2 laser on Polypropylene powder with 200 micrometer grain size. Tensile strength and stiffness had been measured according to ASTM D882 standard and results were reported eventually. In this paper, main effects of factors and interactions were considered via the variance analysis under the imperative conditions that have been passed before. The regression equation was derived finally. A general full factorial method was employed as experimental design. The results show that the laser scanning pattern and laser power have most effects on tensile strength and stiffness of produced samples. The maximum value of responses, 2/9 MPa for mechanical strength and 96 N/mm for stiffness, demonstrate that the 2W power of laser with 1650mm/min of scan speed can be the proper value to obtain an optimal response when the selected pattern is No2.

Abstract

Linear and angular displacement measuring encoders are the most important measuring tools in the industry. Linear encoders are widely used in various positioning applications, such as numerical controlled (NC) machine tools and factory automation, since they are essential for precision positioning systems. In this study, a capacitive-type linear encoder with un-tethered slider is designed. The main components are made of printed circuit films. Hence, the encoder can be set up in thin inter spaces or on curved surfaces. The encoder consists of a long receiver film and a short transmitter film, respectively containing four-phase and two-phase electrodes. The transmitter is used as a slider and the receiver as a stator. In order to designs an unconstrained slider; the encoder employs a unique approach. Electrical power is supplied to the transmitter film by electrostatic induction which removes electric wires from the slider. In this study the encoder was built using a new signal processing circuit and its performance was evaluated. The new signal processing circuit is more compact and facilitates using this encoder for trade purposes. The result of experimental evaluation shows that the encoder has ±20 micrometers error.

Abstract

Nowadays wobble motors are widely utilized as actuators with high torque rotary motion producing capability without the need for external gearbox. This study contains theoretical, numerical and experimental analysis of a planar wobble motor with compliant mechanism driven by shape memory alloy (SMA) wires. The cyclic expansion and contraction of SMA wires is converted to the plane curvilinear motion with circular path and then to the continuous unlimited rotary motion by means of a compliant mechanism and a gear system consisting of an internal and an external gear. After gear system designing based on achievable motion range caused by SMA wires length change, the relations between output torque, geometrical properties of motor and stress in SMA wire were derived. Also compliant mechanism parameters consisting of length, height, thickness and number of flexures were analyzed with the aim of mechanism stiffness calculating. Then the frequency analysis with finite element method is performed to investigate structural robustness and operational stability of designed mechanism. The designed motor is fabricated as a prototype to investigate its operational feasibility and working performances. The experimental results demonstrate motor capability in producing unlimited continuous rotary motion and repeatability of maximum output torque. The Maximum output torque was measured as 29.9, 32.7 and 34. 3mN.m for 1.6, 1.8 and 2v applied voltages respectively. With consideration of motor characteristics, it is appropriate for high torque and low speed applications with limited work space.

Abstract

Deep drawing is one of the sheet forming processes, in which a metal sheet with mechanical operation, reaches the desired shape. One of the most important issues in deep drawing is the optimal design of the initial blank. In this paper, the main purpose is to design the optimal initial blank (with minimum circumference and minimum defects), for deep drawing of parts with a rectangular cross section. To this end, in this study, a program in Visual Basic has been written in SolidWorks software, in which a rectangular piece and press velocity variables take the tensile depth as input and design the optimal blank. Also in this program, blanks with rectangular, circular, octagonal and rhombus contours have been obtained; So that they are tangent to the initial contour. A separate program has also been written to display contour blanks at different times. The blank design program obtained in this study has this unique feature that for any type of rectangular piece and with any desired dimensions, according to the dimensions of the piece and the depth of tension, it will be possible to design the optimal blank. To ensure the accuracy of the program written in Visual Basic language, the results of the program have been compared and validated by performing experimental work. Experimental results prove that the blanks obtained by the program are of acceptable accuracy. In experimental parts, defects such as earring and shrinkage have also been observed in parts produced with optimal blanks.

Abstract

Reinforced concrete structures with standard steel rebar are vulnerable to corrosion and harsh environmental conditions, hence RC structures reinforced with fiber-reinforced polymer (FRP) rebar were commonly used these days. Du to FRP rebar’s better performance such as high strength, low self-weight, electromagnetic transparency and, as mentioned, non-corrodibility nature, using them as reinforcing bar is very widespread now. Because of financial matters, between different kinds of FRPs, GFRP is a better choice. Considering GFRP’s high strength and elastic behavior until failure, Although a large amount of reinforcement ratio is needed in composite beam components, the flexural stiffness of GFRP rebar reinforced beams is relatively lower compared to steel-RC, and more deflection and cracking are allowed in the serviceability design of these beams. Recently, shear and flexural behavior of continuous concrete beams reinforced with GFRP bars has been well investigated. Because of linear elastic behavior of GFRP materials until failure, considering moment redistribution in analysis and design of these beams is not allowed in almost all of cods and guidelines. Although many experimental and numerical researches investigated the moment redistribution in FRP-RC continuous beams with rectangular section, the behavior of these beams with T-section is almost unknown. This paper is a numerical investigation of existence and variety of moment redistribution in concrete continuous T-section beams reinforced with GFRP bars using finite element method with ABAQUS software. The verification of numerical models was done with some experimental beams, so the simulation can be used for further researches. The considering variables included the longitudinal reinforcement percentage, the number of main bars with constant bar ratio, transverse reinforcement ratio, stirrup space with constant ratio and constant bar size. For investigating mentioned parameters, 35 beams were modeled in software according to Canadian design and construction of building structures with FRP code, so 5 groups of beams were made which one beam is constant in each group. T-section beams were modeled assuming which failure happens because of concrete crashing not rebar failure. Deflection and serviceability were not interested, so bond-slippage behavior of GFRP rebar with concrete is not considered in modeling. Problem is indeterminate, so the percentage of moment redistribution was determined by comparing the reactions resulted from numerical and elastic analysis. Load-deflection and load-moment redistribution curves were used to discuss. The results show, as there is in steel-RC structures, moment redistribution exist in GFRP-RC continuous beams with T-section; however the amount of it is lower. Amount of bars between 2.5 times of balance reinforcement ratio and 3.5 times of it, in top and bottom of beam, shows the highest flexibility load and moment redistribution capacity. Increasing the number of main bars with constant reinforcement ratio and increasing the stirrup space with constant transverse reinforcement ratio reduce the moment redistribution capacity. It seems that the minimum amount of transverse reinforcement considered in Canadian code is not enough for preventing shear failure in these beams. So, with considering some points, the moment redistribution can be taken to account in analysis and design of GFRP-RC continuous beams with T-section.

Abstract

When there is a need to transfer power between non-parallel shafts, bevel gears are used. Bevel gears are widely used in power transmission systems such as car differentials and helicopter gearboxes, so knowing and improving the performance of this type of gear is particularly important. It is important and necessary to accurately calculate the machining time of the desired bevel gear in order to reduce time and costs. In this paper, data are collected using Taguchi's test design method in three levels. The amount of machining time was calculated for each test, then with the help of signal-to-noise analysis, the influence of the input parameters on the design of the straight tooth bevel gear on the reduction of the machining time has been investigated. The investigated parameters are conversion ratio, allowable contact stress and allowable bending stress.According to the obtained results, the conversion ratio parameter was found to be the most effective parameter on reducing the machining time. The optimal value of the conversion ratio was reported at level 1 with a value of 1.5.
