Abstract

Uncoated fish burgers were produced in order to expand the variety of products from Silver carp, Hypophthalmichthies molitrix ,and increase the consumption of this fish species. On the other hand in order to compare the effect of ascorbic acid and vacuum packaging on rancidity inhibition and microbial quality, 3 different treatments of fish burger were produced: 1. Burger with common packaging (Control group), 2. Burger with vacuum packaging 3. Burger with 500 ppm ascorbic acid in common packaging. All the treatments were stored in -18 ºC for 6 months after freezing by a spiral freezer in -35 ºC. Chemical, microbiological and sensory evaluations were determined from time 0 and after that monthly until the 6th month. The TVB-N value increased during the storage period but it never passed out of the standard range. The TBA value increased in all treatments but in ascorbic acid treatment it was significantly lower than the other two groups. The pH amounts during storage period decreased in all treatments homogeneously. Microbial counts in all treatments and especially in vacuum packed burgers decreased during the storage period. Organoleptic test demonstrated the preference of burgers treated by ascorbic acid. The shelf life of control group and burgers with vacuum packaging was determined 3 months at least. The shelf life of treated burgers with ascorbic acid was determined about 6 months specially based on the TBA index and sensory evaluation. Vacuum packaging was more effective to protect burgers of chemical and microbial changes compared to common packaging.

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

Aims: Infertility can cause social stigma and erode sexual self-esteem in women, highlighting the need to explore interventions like mindfulness-based cognitive therapy to address these challenges. The present study aimed to investigate the effectiveness of mindfulness-based cognitive therapy on infertility-related stigma and sexual self-esteem in infertile women.
Materials & Methods: This was a three-stage (pre-test, post-test, and follow-up) two-group (experimental and control) quasi-experimental study. To conduct the study, all infertile women referred to infertility treatment centers in Isfahan City in early 2023 were recruited using a convenience sampling method based on inclusion and exclusion criteria. A total of 40 participants were randomly assigned to either the experimental group (n=20) or the control group (n=20). The sample group completed the Infertility-Related Stigma Questionnaire and the Sexual Self-Esteem Scale in three stages: Pre-test, post-test, and follow-up. The experimental group received an 8-session MBCT (one 90-minute session per week). Repeated measures ANOVA was used to analyze the results.
Findings: Mindfulness-based cognitive therapy significantly improved infertility-related stigma in the social withdrawal, family stigma, and public stigma dimensions (p<0.01). However, the intervention was not significantly effective in enhancing sexual self-esteem in infertile women.
Conclusion: Mindfulness-based cognitive therapy significantly reduces infertility-related stigma, specifically in the social withdrawal dimension.

Abstract

Among the sources of oils (vegetable, animal, microorganism), microbial oil has attracted the attention of many researchers. Oily microorganisms are able to accumulate 20 to 80% of lipids in each dry biomass. Among various microorganisms (bacterias, microalgae, fungal species including yeasts), some yeasts are considered to be the superior source of oil production. Yarrowia lipolytica is an excellent example of oily microorganisms with high fat production efficiency. By using cheap, native and available pulp as a production medium, the cost of oil produced by yeasts can be reduced. The microbial oil produced is used for medicinal, food and cosmetic purposes. In this study, the pleomorphism of Yarrowia lipolytica (ATCC 18942) was examined microscopically in different culture media. After culturing the  yeast in media containing olive, sesame and sunflower pulp, in semi-open culture conditions, the fatty acids produced were analyzed using GC-MS and FTIR techniques. After reviewing the results, the medium containing olive pulp was selected and the microbial lipid produced in this medium was extracted. Then dry weight of biomass and microbial fat were measured. The results showed that the fatty acids extracted from the medium containing olive oli cake included oleic acid, palmitic acid, linoleic acid and stearic acid, which had the best production of fatty acids among the pulp. The content of  microbial fat and dry weight were 4.07 and 7.83 g/l, respectively, and microbial fat production efficiency was 51.97%.

Abstract

Galloping of cables is a kind of self-excited vibration and characterized with high amplitude and low frequency vibration. In this paper for investigating the nonlinear galloping of an inclined cable, considering flexural and torsional stiffness, a cable-beam model is used. The iced cable is formulated under the effects of combined wind flow and support motion. Assuming low sag to span ratio and using physical parameter values of the cable, the governing equation of motion is obtained as a classical equations of the perfectly flexible cable, plus a further equation governing the twist motion. These two degrees of freedom system is discretized via the Galerkin method, by taking in-plane and out-of-plane modes as trial function. Two resulting non-homogeneous ordinary differential equations are coupled and contain quadratic and cubic nonlinearities in both velocity and displacement terms. By using multiple scale method for 1:1 internal resonance, a first order amplitude-phase modulation equation, governing the slow dynamic of the cable, is obtained. In this paper the wind speed and the eccentricity of the iced section are set as the control parameters. Without consideration the eccentricity, the value of amplitude is increased as the wind speed is increased. But considering the eccentricity is reduced to firstly increasing and then decreasing the amplitude.

Abstract

Financial development is one of the most important causes of economic growth in the long run. The study of factors affecting economic growth, as a key economic target, is of great importance. In this paper, the effect of financial development on the economic growth is studied in Iran during 1989 to 2016. In order to increase the accuracy and flexibility of results, this paper uses the Time Varying Parameter Factor Augmented VAR (TVP-FAVAR) model, which makes possible to change coefficient and to contribute the individual variables at any point of time. First, the latent variable for financial development is estimated in the Iranian economy. Then, a model is specified including the variables of liquidity volume, oil revenues, economic growth and financial development. The results of the impulse- response functions show that a shock to the financial development has a positive effect on economic growth during the period under study. In addition, the shock from oil revenues only leads to an increase in economic growth over the short term and adjusts over several years, while the liquidity shocks have no significant effects on economic growth in most years.

Abstract

In this research, taking into account the pressure drop of the streams, a simple and useful method is presented for finding the proper path of hot and cold streams inside shell-tube heat exchangers in the synthesis of heat exchangers networks (HENs). Generally, the HENs synthesis by mathematical programming leads to the problems which are answered by Mixed Integer Non Linear Programming (MINLP) methods. Optimization of such formulations results convergence difficulties due to the existence of both continuous and integer variables. In this study, instead of solving simultaneously integer and continuous variables, the genetic algorithm was used to find optimal HEN structure (integer variables). To find optimal values for continuous variables of the network, by categorizing this type of variables into two groups and using Quasi Linear Programming (QLP) instead of the nonlinear programming model (NLP), the complexity of the NLP model solution is also greatly reduced. The optimal values of continuous and integer variables are obtained with respect to a common objective function that reaches the minimum annual cost of the HEN. The comparison of the proposed method with the references shows that this method has the ability to reduce the cost of pumping flows to about 0.76%.

Abstract

Today, piezoelectric actuators are widely used in micro-positioning applications due to unique features such as high precision, fast response and high natural frequency. Despite the aforementioned characteristics, nonlinear characteristics such as hysteresis deteriorate the precision of piezoelectric actuators. In order to reduce the effect of hysteresis in control applications, external sensors are used for feedback control schemes. But, high costs and space limitations are prohibitive factors which limit the application of external sensors. Hence, an alternative is using self-sensing methods that is based on electromechanical characteristics of piezoelectric materials which eventually eliminate external sensors. In this research, self-sensing method is applied for position estimation in piezoelectric actuators. The most conventional method is based on the linear relation of electrical charge and actuator position which the position can be estimated by measuring the actuator charge. But this method is faced with serious challenges due to charge drift, especially at low frequencies. For this purpose, a method for modeling and compensating of charge drift is proposed. Then, by linearization of the electric charge-position relation, the self-sensing method is implemented based on the compensated electric charge measurement. Experiments have confirmed that this method can effectively estimate the actuator position with 1.5% estimation error in the presence of charge leakage.

Abstract

Flap-type WECs are used On-Shore to generate electricity and pump. The draft depth and incident wave frequency are parameters affecting the performance of this type of converters. In this paper, the effect of water draft depth and incident wave frequency on the performance of a converter at a scale of 1: 8 investigated experimentally. The power take-off system is hydraulic. The Caspian Sea was also selected as the target sea. After calibration and uncertainty analysis, experimental tests performed in the wave-flume of BNUT by regular waves. Considering the period of the Caspian Sea ([4-8] s), Froud scaling, the tests were performed in the period interval of [1.6-2.5] s, which is equivalent to the frequency interval [0.4-0.63 ] Hz. Also, due to the importance of the converter's draft, the converter's performance was evaluated from the draft of -0.1 (submerged flap) to 0.6 m. According to the results, the best converter performance was at the lowest frequency; the converter performance decreased with increasing frequency. The best converter performance was obtained at the dimensionless draft of 0.43 (equivalent to 0.4 m draft), and the converter power was reduced at larger and smaller draft. It is worth noting that at a negative draft (submerged flap), the converter has the lowest performance. The maximum values ​​of flow, power and pressure on a laboratory scale were 0.14 liters per second, 21.3 watts and 156.8 kPa, respectively, which were measured at 18 liters per second, 22.66 kW, respectively, using Froud scaling method. And will be 1249/61 kPa
