Objective: In order to achieving the development, at first, we must be precisely defined this concept and identify its purpose. For preparing development path, it is essential a cultural transformation in the community. We have to understand the process of cultural transformation, at first, investigated to the experiences of the impact of communications technology on the culture field. Methodology: If communication initially cause a convergence wave in accordance to the opposition between social advantage and individual benefits, whatever decision makers carry out toward the dissemination of aim, public acceptance would gained, otherwise the communication project would be useless. In trying to create such a wave, the monotheism word recognition and fostering breath ethical aspects are two steps that between social interests and material interests of individuals establish unity and harmony. Transformation of Society would occur following the unity and harmony of the people world, the ideas world and the objects world with each other and with the aim of collection. In the most widespread of spiritual mode, the traits are under the control of the soul and all forces in society have the transcendental movement. Results: With the fading of spiritual, the traits are dominated by wisdom, all forces are not on the move and their moving parts, as well as overall, is not in the transcendental. With the loss of spiritual, the traits dominated by instincts are torn of together and becomes dominant individualism, this is the same situation that history calls it the era of decadence. Conclusion: Of course, evolution, fertility and its compatibility with social-economic environment of contemporary period requires much time and effort. This researcher, while visiting the books, articles, magazines and journals that was somehow related to the issue, he is collecting literature and theoretical foundations in this context and then is used the method of inductive research.

Published: March 2022

Many people's lives and property are threatened by annually around the world. Thus, it is necessary to identify areas with flood risk in order to apply systematic management in urban auriferous zones. First, topographic maps and Si valley Shirvan River aquiferous land use was prepared and river basin border was drawn based on these maps, then the river divided to 3 sub-basins and these sub-basins divided to 5 hydrological unit and these units divided to 4 sub- hydrological units, and flood hydrographs were calculated in return periods of 2, 5, 10, 25, 50, 100, respectively. Within the area of S1-1-1 with a length of 3.5 km in Si valley Shirvan River, geometric information of river was obtained. In the next stage, by introduction of flow characteristics and river geometric information and each profile coefficient in HEC_RAS software, water level profile in different return periods was calculated and average level and depth of flood for risk areas was determined. Finally, using flood damages functions, damages were calculated and level-damage curve was drawn. The results showed that damage increase trend of floods with a return period of more than 25 years and average flooding depth greater than 0.52 m is more intense.

The Effects of Iron Fertilization and sulfuric acid Application in Irrigation water on Root Growth and Chemical composition of Bean cultivars in a Calcareous soil
Authors: Jozdaemi Elham , Golchin Ahmad 
Published: March 2022

Legumes are main sources of plant proteins for human and animal nourishment. Beans with 20-25% protein, 55-65% carbohydrates and 1-5% lipid play a major role in nutrition of poor nations which are not able to feed ourselves with animal proteins. Thus, increasing yield and quality of beans is an effective way for reducing protein deficiency in developing countries. One of the factors that reduces yield and quality of beans in calcareous soils of Iran is iron deficiency. High pH and calcium and bicarbonate contents of calcareous soils induce leaf choruses which limits plant growth and yield and reduces the quality of beans. To determine the effects of soil and foliar applied iron fertilizers and sulfuric acid on roots of four spotted bean cultivars, a factorial experiment was conducted using a completely randomized design and three replications. The experimental factors were iron fertilizers and bean cultivars. Fertilizer factor included: (a) soil application of ferrous sulfate (25 and 50 mg/kg) and Fe-EDDHA (3 and 6 mg/kg), (b) foliar application of Fe-EDTA(1 and 2 mg/L) and ferrous sulfate (2 and 4 g/L), (3) soil application of sulfuric acid through the irrigation water (2 and 4 g/L) and (4) control (without iron fertilizer).The spotted bean cultivars used in this study were Tallash, Khomein, COS16 and a Local cultivar. The results of this experiment showed that there were significant differences between the effects of soil and foliar applied iron fertilizers and spotted bean cultivars root with respect to root dry and weights. The bean cultivars responded differently to iron fertilization and the highest and the lowest increase in root dry and weights were measured for the local and Khomain cultivars respectively . The results of the experiment showed that application of sulfuric acid by irrigation water at the rate of 4.mg/l increased the fresh and dry weight of root. The application of sulfuric acid also increased the root concentrations of N, K, P, Fe, Cu, Mn, and Zn significantly . The application of soil and foliar applied iron also increased the root concentration of Fe, K, N, P and decreased the root concentration of Cu, Zn, Mn.

Published: March 2022

The economization and commercialization of the bio fuels production from microalgae require solving some problems facing it. One of the most important and expensive stages is the separation of microalgae from the medium culture. The modelling of Separation biological processes can be used as a safe tool to save the economy and avoid repeated testing. Among the methods of modelling, artificial neural network is accurate and widely used in biotechnological processes. Results of the study showed that correlation coefficient reached 1 indicating that there is a good match between actual values and those predicted by modelling. From a total of 18 data, two-thirds of data was used to train a network and the remaining third was used to assess the modelling accuracy. The middle transition function purelin , output transfer function tansig and the number of neurons (five) were determined as the best parameters to train the network. The error rate of network training was estimated to be 0.0511 and error evaluation of the network accuracy was found to be 0.992.
First and second lining vibration design of urban tunnels in Tehran ABAQUS software
Authors: Kasiri Ghahi Mahdi , Sanaeirad Ali 
Published: March 2022

Nowadays, a great portion of transportation is being accomplished through underground structures. As such structures are embedded into the ground and there is a remarkable interaction between them and the surrounding soil, very little attention has been paid to the impact of earthquake on these structures. With respect to the increase in rate of transportation as well as decrease in depth to the ground surface, the safety of these structures against earthquake need to be taken into account much more carefully. Due to the importance and diversity of this issue, design of tunnel linings has been widely investigated so far. In this respect, one of the questions that arises in engineers’ minds is regarding the time duration of stresses release after excavation until execution of the concrete lining. Accounting for the stiffness of the permanent lining, in the beginning of the analyses, is so conservative such that in case of soil or rock mass with high overburden, irrational results will be obtained. The main objectives of this research is to obtain seismic and dynamic results of metro tunnels supported by concrete linings and specify the significant and effective parameters on seismic design of such underground structures. By means of applying two types of vibration including periodic loads as well as base excitation using accelerograms, the impact of surcharge on seismic response of the lining was studied. Among the results, the maximum displacement was related to the KN60 surcharge. Regarding the effect of soil elasticity modulus on displacements, it can be concluded that increase in this modulus, reduces the displacements and the considerable reduction takes place when the increase is in the range of 20 to 40 MPa. Moreover, increasing the Poisson ratio led to a little increase in dynamic response of the lining

Authors: Mosavi S.F. , Sadegi N. 
Published: March 2022

Introduction and purpose: The infancy is one of the most sensitive stages of life which is requiring the suitable recognition and proper care delivery. Since the family is considered as a valuable element in determining the goals and determining specific needs and carrying out interventions for providing services to infants, the awareness of parents, especially the mother about how to correct behaviour with infant's problems and provide essential care in this per iod can notable contribute to improving infant's health. Therefore, according to this point, it is necessary to examine the families' awareness about the child care standards. The aim of this study was to determine the relationship between family function in the context of infant care standards with some family specifications in the families referred to clinics of the city of Ardabil in 2017 year. the research method: in this study, 132 families having newborn children referred to the Ardabil city's clinics were studied, which were selected in the available method. The data were collected through a questionnaire whose validity and reliability were also carried out. The data were analyzed by SPSS software. Findings: Out of 132 studies, 60 people (45 %) were girls and 72 (55 %)were boys. the results showed that as family specifications improve, child care standards will increase. As well as their age in family functioning is ineffective in the context of child care, but economic status and birth order variables have an not effective role in family function. Discussion and conclusion: This study revealed that family function in the context of infant care standards is closely related to some family specifications as well as family specifications are capable of predicting the infant care standards, so as the family specifications increase, child care standards will also increase. Therefore, the most participation of people in respect of infant care is one of their effective means of empowerment, increasing the quality of child care, as well as raising the community health level. The rate of growth in early childhood is very high. The experiences children receive from their surroundings in these years are used as basis and basis for subsequent cross - learning.
