Abstract

 Small and mid-sized enterprises (SMEs) have played a significant role in the growth and advancement of the Chinese agriculture sector. However, these enterprises often face challenges in navigating local distribution networks, complying with regulations, and procuring local consumer products, which can hinder the marketing environment and impede economic growth. To address these issues and promote continuous business development, Chinese agriculture enterprises require effective modeling techniques that facilitate transformation to meet evolving requirements. This study proposes a game-theoretic approach, specifically the Mixed Strategy Game-Theoretic Approach (MSGTA), as a decision-making tool for enterprises facing pre-emptive changes. By analyzing oligopoly firm behavior, the MSGTA approach identifies enterprise outcomes, cooperation patterns, and price-fixing strategies, providing decision-making options and incentives within the enterprise structure. The MSGTA approach assists SMEs in the Chinese agriculture market by systematically analyzing product development stages and ensuring the effective adoption of pre-emptive changes. The efficiency of SMEs implementing the MSGTA approach is evaluated by examining statistical relationships between enterprise growth and requirements. By integrating effective modeling techniques, Chinese agriculture SMEs can adapt to changes proactively, enhance their ability to navigate local distribution networks, comply with regulations, and procure local consumer products more effectively, thereby improving the marketing environment and fostering economic growth.

Abstract

one of the most important ways to realize the resistive economy is to support the small and medium industries and create a sustainable capacity in them to deal with the environmental changes and threats. In the management science, achieving such a goal is manifested in the concept of the organizational resilience. Therefore, the present study is aimed to identify and rank the most important affecting factors of the resilience of small and medium industries in order to provide practical solutions for managers and relevant authorities. For this purpose, 10 experts and managers of these industries have been interviewed and with the help of the theme technique, the affecting factors on resilience have been identified and Then 14 experts have ranked these factors by questionnaire method and using the analytic hierarchy technique. The results have shown that the intra-organizational factors have a greater effect on the resilience of the company than the extra-organizational factors. Among the intra-organizational factors, the management factor with the sub-criteria of attitude to change has the highest priority, Also, among the extra-organizational factors, the factor of organizations and trade associations with the sub-criteria of amendments, and the factor of governmental support with the sub-criteria of exemptions and tax rebates are respectively in the first and second ranks.

Abstract

Research subject: Aspergillus niger stands as a versatile filamentous fungus renowned for its industrial significance in producing various organic acids, notably citric acid and oxalic acid. Low sugar concentration as substrate leads to the production of oxalic acid, therefore, this article delves into the intricate metabolic machinery orchestrating the synthesis of these acids within A. niger, shedding light on the pivotal role of culture media composition and metabolic activity.
Research approach: Through a comprehensive review of A. niger metabolism, this study elucidates the pathways involved in the biosynthesis of citric acid and oxalic acid, unraveling the intricate interplay of enzymatic cascades and regulatory mechanisms governing their production. Furthermore, it explores the impact of small molecules on metabolic flux through regulatory media, offering insights into strategies for controlling metabolic flux in order to eliminate oxalic acid production and amplify the citric acid production considering low sugar content of 30 g/l.
Main results: After careful review of previous researches, key reactions and genes was found and introduced for future researches in order to control the A. niger products. Examination of small molecule as a regulator in culture media not only elucidated the importance of culture media composition but also employing them helped us to redirect flux from oxalate toward citrate. NH4, Leucine, Cysteine, NaF, Glutathione, and Metformin were all found to be effective in the elimination of oxalic acid. In this regard, employing them leads to the production of 1868, 1530, 2093, 2250, 787, and 675 mg/L oxalic acid in comparison to the control culture media in which 5560 mg/L oxalic was produced. In addition, elimination of oxalic acid in some cases leads to the production of more acids like the culture containing NH4, Cysteine and Metformin.

Abstract

In this article, one of the most iterative examples of Iranian tales and myths, heroism and the victory of the last child, has been examined, based on the ancient examples of the child's model from the view point of Jung. Son or the third daughter, fourth, seventh, fortieth or hundredth, who is in fact the youngest child, fights against his brothers and sisters in a scene of balanced struggle and triumphs. In this paper, several types are first selected and for each type, a story has been chosen. Then, the stories are examined according to the three characteristics that Young attributes to the child's old model. The results indicate that the latest children of tales with smaller than small while bigger than big character than Jung model have a close connection with the three attributes of rejection, invincibility and hermaphroditic talent.

Abstract

Although the research on small clauses ages over 30, the syntactic nature of small clauses is still a challenging and controversial issue among linguists. In this paper, we start with a brief discussion of the background of the works and approaches related to the nodes governing small clauses. We continue with some arguments in rejecting or accepting some of these approaches. Finally, we describe the construction of secondary Predicative Structures (small clauses) in Persian based on Bower's Minimal Approach (1993, 2001). Based on this approach, these structures consist of [NP XP] and are Tense-less, and their XP is non-verbal. This study assumes a binary-branching structure for small clauses. According to the authors' analyses, in all languages,​​ small clauses which include the subject and the predicate are the functional projections of the predicate, and their difference is only in the concept of the predicate head and its characteristics.

Abstract

This essay tries to show a frequent macrostructure in mystical Maqâmâts that makes people`s religious beliefs. Not only does it gives enough evidences for the structure but also interprets its ideological functions. The macrostructure consists of some chronological events. It starts with a holy parentage for great Sufis and it is continued by prophecies predict a child will be a great Sufi in the future. It carries on with unbearable asceticisms. All of the events prepare the ground for small miracles. The chain ends with a fantastic death and a contrast to other discourses. The last events, in reality, work as a result of small miracles power. The main function of the structure appears to make a limitation to access to small miracles. It leds to articulations that generate a new discourse: discourse of Sufis who have small miracles. The new discourse encounters mystical discourse to social and political discourses.

Abstract

The people and nation of Central Asia: Turkmans live in the north of Afghanistan and the east of the Caspian sea and at some parts of Turkmenistan and Uzbekistan.Iranian Turk-mans live in the north east of Iran in Turkman Sahra.They have a special, rich and indige-nous culture. There are many fables and beliefs on the making of Turkman carpets. Here we recall the tale of “Agh-Morad”3 . Most of the designs used in the “Pazirik”4 carpet are quite similar to those of Turkman. Turkman carpets are weaved by women in a way that differentiate them from other carpets. Up to 25 colors are being used with approximately 40 designs. Turkman carpets resemble paintings of the museums and royal castles. The raw materials used to weave Turkman carpets are wool, fluff, cotton and thread. The weaving tools are hackle, small knife, scissors and Anavich. Today there are two types of carpets in Turkman Sahra: Satligh (for business) and Tootligh (for own use). Another important aspect contributing nation’s cultural heritage is turkman music which is reminiscent of the people’s old traditions and sensational epics, which they singin bitter sweet sorrows and joyous way. This article discusses about the history of Turkman music and the position of the Bakhshies in Turkman Sahra (the desert of Turkman) and their way of living. Turkman music comprises affectionate, serenading, epic and warlike, festive and ceremony. In view of its style of performance, Turkman music is either, instrumental, vocal or instru-mental-vocal. It is also known as field or mountainside music according to its geographical location. The common musical divisions of Turkman are Mokhammas (pentagonal), Navayee, Ghe’re’ghler and Tashnid or Tajnis. With approximately 500 Maghams (tunes) In Turkman music Turkman’s musical instruments are Dotar, Ney (pipe), Kamancheh (vio-lin-like instrument resting on the ground during performance) and Zanboorak (crossbow). There are people called Porkhan who use music in their medical practices. The fables and folklore of the Turkman people also play Iran’s cultural heritage and reflect the depth of their attitudes, thoughts and ideals and even their way of living. The main part of Turkman folklore is made up of oral literature which includes: -Laleh (a lyric sung by Turkman girls) -Artaki and tales -Ataladi Souzi (proverbs) -Zekr (sonnets and the dagger dance) One of the most important Turkman fables is a tale about their ancestors in which a man named Yafes is introduced as the great ancestor of the Turk and Turkman people. According to folklore the people of Turkman originated from 24 tribes, each of them had a special symbol like eagle, falcon and so on. Among them three are in Iran: Tekkeh, Yamout and Googlang. Turkman people believe in lucky and unlucky days. There is a well-known story called “Agh Pamegh” in this regard.

Abstract

  The paper tries to present an improved mathematical model for distribution companies (DISCOs) in order to solve Distribution Network Expansion Planning (DNEP) problems in the presence of certain resources of Distributed Generations (DGs) entitled small scale Gas Engines in the medium voltage grids. With the aim of minimizing investment and operation costs, the recommended model combines a comprehensive multi-objective optimization model with grid designer’s experience and power transit possibility in retail trading. The proposed model determines the optimal capacity of new transformers, and the most efficient type and route of the expandable medium voltage feeders under probable power transit condition in retail markets. In addition, this model maintains system reliability along with an innovative formulation. The scenario-based results obtained after implementing this method on a typical distribution grid modeled under GAMS software platform indicate that the proposed model is really suitable for expanding distribution grids.

Abstract

Aims: Haft Barm is a series of five small lakes in the southern Zagros region which has encountered recent rapid development of human settlement. This article reports a survey on its essential ecological attributes.
Methods: Water samples were taken from three locations in March and June 2020 and analyzed regarding physical and chemical factors and plankton communities. Trophic state and primary production were estimated.
Findings: Results showed water temperature 8.2–23.1 °C, dissolved oxygen 6.3–8.3 mg.L-1, salinity as electrical conductivity 739 – 971 µS.cm-1, total nitrogen 0.1–1.1 mg.L-1, and total phosphorus 0.4 and 3.8 mg.L-1. Algae of the lake consisted of 24 taxa, the highest density of which counted 23360 cells per liter in June, and the Chlorophyceae were the dominant group. The Zooplankton composition was of four taxa from Cladocera (Bosmina sp. and Daphnia sp.), Copepoda (Cyclops sp.), and Rotifera (Rotaria sp.), with the highest densities in Rotaria (35 individuals per liter). Phragmites sp., and Juncus sp. were the dominant species in the macrophyte community besides Polygonum amphbium, and Potamogeton pectiatus. The very high concentration of total phosphorus is a strong sign for predicting a eutrophic condition. The average trophic index is estimated at 88, which suggests a eutrophic to hyper-eutrophic state for the lake. The estimated primary production of the lake was 1114 gC.m-2.A-1.

Abstract

The Persian morpheme ra has attracted the attention of many linguists including Karimi (1989), Dabir-Moghaddam (1990) and Ghomeshi (1996) among others. Karimi takes ra as the accusative case marker, the presence of which on subjects and objects of prepositions render the sentence ungrammatical. According to Ghomeshi (1996), it marks DPs functioning as VP-level topics. Dabir-Moghaddam (1990) analyzes ra as the secondary topic marker in the Halidayian Functional grammar framework. In none of these analyses, this morpheme appear on deep subjects. In this article, it is highlighted that ra may also mark subjects, just in case it occurs in the right grammatical configuration. More specifically Persian has the category of small clause in which an NP marked with ra is the subject of the small clause rathar than object of the matrix sentence. This is an unprecedented hypothesis in Persian linguistic literature. I also present a minimalist account of the construction in question.

Abstract

Creating and supporting small and medium-sized industries in economic development programs and the emphasis on improving efficiency and productivity in the policies adopted, shows the vital position of such industries in developed as well as developing economies. In general, the most important role of these industries in the economic development process can be summarized as; effective employment, production and supply chain management, creating value added and reducing dependence on unnecessary commodity imports. Since any improvement in the efficiency of small scale industries will bring more equitable distribution of income, the main purpose of this study is to measure the performance of various technical, management and scale efficiencies in subsectors of small scale industries and provide policy recommendations to the inefficient industries. For this purpose, the principal component analysis (PCA) and factor analysis is used to determine the variables of the model and the DEA is used for evaluation and sensitivity analysis of the factors affecting the efficiency and productivity of small scale industries during the period 2002 - 2007. The results show that out of 22 industries, only 8 ones are found to be perfectly efficient. Productivity measurement of these industries according to the "Malmquist" index reveals that, the trend of productivity enjoys positive growth.

Abstract

Background: Lung adenocarcinoma is the most primary histologic subtype of non-small cell lung cancer (NSCLC). Oxypeucedanin methanolate, a member of furanocoumarin, is a naturally occurring compound, which is isolated from Ferulago trifida Boiss, an endemic species in North-West of Iran.
Purpose: We attempt to uncover the capacities of oxypeucedanin methanolate to induce apoptosis and autophagy in NSCLC cells, as well as the underlying mechanism involved in this process.
Methods: The effect of oxypeucedanin methanolate on cell viability was evaluated on A549 cells by MTT assay. Flow cytometry assay was used to detect cellular apoptosis. Expression levels of BAX, caspase-3, BCL2 and LC3 in A549 cells were measured by Real time quantitative reverse transcription-polymerase chain reaction (Real time RT-PCR). A549 cells migration were analyzed using a wound‐healing assay.
Results: Oxypeucedanin methanolate inhibited A549 cell proliferation in dose- and time- dependent manner, as evaluated by MTT assay. The total apoptosis rate was (5.46%) for A549 cells not treated with oxypeucedanin methanolate. In contrast, the apoptosis rate was (29.6%) for A549 cells treated with oxypeucedanin methanolate at the concentration of 0.4 mM. Real time RT-PCR revealed that the mRNA expression of BAX, caspase-3 and LC3 were upregulated, while mRNA expression of BCL2 was downregulated. Untreated cell migration increased significantly after 72 hours.
Conclusion: Oxypeucedanin methanolate inhibits proliferation and it could induce apoptosis and autophagy of human non-small cell lung cancer cell line A549. Oxypeucedanin methanolate may be a good candidate for reducing of A549 cells metastasis.

Abstract

Technology has become a quintessential component of educational practice over the past years. Research in this area has shown that the integration of various technologies positively contributed to language education and facilitated learning different language skills. Despite the extensive application of computer assisted language learning for adults, little research has examined Young Language Learners’ (YLL) language development through technology. In this regard, the current study investigated the impact of using a mobile technology on YLLs’ (age range: 6 to 8) vocabulary development. Seventy-one learners participated in the study who were divided into a control (N = 32) and an experimental (N = 39) groups. Data were collected using a vocabulary test in three rounds of pre-test, post-test, and delayed post-test. The collected data in terms of vocabulary test scores were analyzed using mixed between-within subjects analysis of variance. The results revealed that the experimental group who used mobile devices for vocabulary learning outperformed the control group in the posttest and gained significant improvements in the delayed posttest. The study provides implications for various educational stakeholders including teachers, learners, and material developers to exploit the affordances of technology in effectively contributing to YLLs’ vocabulary development.

Abstract

  The results of this study show that, fictional scenario has simple language. Unlike shot by shot scenarios which are based on camera movement, these types of scenarios demonstrate narrative elements. This literary genre has tenfold difference with novel, documentaries and animations. This genre benefits from four distinct systems: 1. the system of action (character’s action / action of plot –space / time and action of displacement / the link between two spaces) 2. The system of non-verbal behaviors of characters.3. Phonetic system 4. The system of music. To investigate and analyze these systems, among three compiled children scenarios of 1360s, fictional scenario entitled “small wishes “has been selected.

Abstract

Entrepreneurship is a general term that is used to both organizations and individuals. Therefore, we cannot imagine an entrepreneur organization that its people do not accurately understand about their ability and creativity. Entrepreneurship acts as a driving force towards people and firms development. We cannot expect an organization’s development without consideration of its people. SMEs want that profitable companies should use all of their capacities and it is easy with entrepreneurship. This paper focuses on the main factors as management, organizational structure, strategic components, financial and budgeting systems, evaluation of performance and cultural aspects in SMEs and surveying of their roles on entrepreneurship filed in companies. The data required were collected through questionnaires that offered to the employees and managers of 25 companies in Kurdistan province. The research method was casual comparative. Findings of the paper showed that entrepreneur firms mangerial skills have a meaningful difference to those of non entrepreneur mangers. This result is true for the financial and budgeting systems and evaluation of performance and cultural characteristics in the studied groups. There was no significant difference in the structural variables (concentration and formality) and the strategic aspects (goal setting and policy making) in the two firms. The results also showed that entrepreneur organizations are more complex than others. Consequently, the innovators of small and medium enterprises have a good mission statement in comparison to non entrepreneur firms.
