Wisdom is a complex concept for which an accepted definition has not been presented yet. However, experts generally agree that wisdom consists of knowledge, insight, reflection, and the combination of an individual’s interests and others’ welfare. Due to the mysterious nature of wisdom, it has been the focus of research in different times, places and cultures. Since wisdom has a close relation with culture, and no clear definition of wisdom is available in Iranian culture, the present study analyzed and discussed wisdom and wisdom features in Shahnameh through the comparative study of characteristics of wisdom behavior in Zal based on Ardedt’s three-dimensional model. The population of this qualitative study included Ferdowsi’s Shahnameh. Through purposive sampling, Zal was selected for further analysis. Shahnameh’s content was analyzed through open coding, axial coding, and selective coding. Findings showed that wisdom features include religiosity and ethics, thinking/ awareness, perception of facts and lack of subjectivism and projection, empathy / affection and support/ service, communication and acquisition of cultural experiences and values. Furthermore, results showed that it is possible to express wisdom in five different dimensions, including spiritual, cognitive, reflective, emotional, social and cultural dimensions.

Wisdom is a multi-dimensional concept, which includes a variety of issues such as knowledge, excitement, self- regulation, motivation, social function, moral and as well complex relationship between these aspects. The concept of wisdom influences on the way thinking, feeling and people's behavior in the life of texture. Therefore, wisdom should accrue in person's performance until it created positive effects for oneself and others. Because, a person that has only ideas of wise, but there is nothing from it in his behavior, that person is not wise. Therefore, aimed this study to investigate low-wise properties of Ferdosi's belief based on Key Kavus personality. This study was conducted based on the framework of quality approach. Statistical population of the research includes Ferdowsi's Shahnameh, which is selected using a meaningful sampling of Key Kavus personality a low- wise one. The context of Shahnameh was using content analysis and processes in clouding implementing, open coding and selective coding. The finding showed that low- wise properties include lack of religiosity and lack of morality, lack of thinking/ awareness, lack of facts perceptions and Subjectivism / Projection, lack of empathy/ affection and lack of experience gaining and lack of cultural values.

Active techniques based on the switched-capacitor converters (SCCs) are used in recent years widely for battery cell balancing applications, due to lack of bulky magnetic components. In addition, these converters are easily be integrated to reduce the volume. Despite of all these benefits, SCCs have some disadvantages such as number of active switches, currents spikes, low balancing speed, and high switching losses. In this paper, a chain resonant SCC is analyzed which can realize soft switching under the ZCS conditions to eliminate currents spikes to overcome the aforementioned SCCs drawbacks. Also, it has been modified to increase balancing speed of the Lithium-Ion battery cells. Then, a chain resonant SCC for balancing a combination of three battery cells with capacity of 2150 mAh and nominal voltage of 3.6 V has been simulated by MATLAB/SIMULINK and it has been implemented at 50 kHz to confirm operation of the converter. The simulation and experimental results are in good agreement with the given mathematical analyses and illustrate that the balancing speed has been improved more than three-fold, as compared with the conventional converter.

  In this paper, a new configuration for delta conversion UPS is proposed, which could help the system for better utilization of the UPS inverters. In this configuration, parallel and series inverters of the conventional delta conversion UPS, under the grid fault conditions, are connected in parallel which help to share the load power and this results in utilizing the series inverter during fault mode. Therefore, using this configuration not only decreases the total capacity of the UPS inverters, but also decreases the system total cost. In the proposed configuration, two inverters have the same sizes and specifications which results in the system modularity that simplifies its implementation and maintenance and reduces the manufacturing and life cycle cost of the UPS system. In addition, the proposed configuration increases the system reliability. To illustrate proper operation of the proposed configuration, some simulations are carried out under the different conditions. The given simulation results validate appropriate operation of the proposed configuration.

Objective: Tissue engineering, as an interdisciplinary field, assists cell therapy by using scaffolds, cells, and growth factors since 30 years ago. Cells isolated from the body should be supported by a scaffold which could mimic the function and structure of natural extracellular matrix (ECM). To accomplish this goal, we have fabricated and characterized synthetic wet electrospun poly(lactic) acid (PLA) scaffolds.
Methods: ThePLA polymer was used at various concentrations (10%, 13%, 15%, 17%, 20% w/v) with a novel architecture produced by a wet-electrospinning process for tissue engineering applications. In the wet electrospinning method, we used an aqueous solution of sodium hydroxide (NaOH) as the coagulation bath. Then, we characterized the biocompatibility and morphology of these scaffolds by the MTT assay and SEM, respectively.
Results: The data collected from the characterization of scaffolds and in vitro human Wharton’s jelly-derived stem cells/scaffold culture showed that the 15% w/v of PLA with high porosity was the best polymer concentration in terms of cell attachment and proliferation.
Conclusion:Electrospinning PLA at the 10% or 20% w/v concentrations was difficult. Additionally, they could not provide a favorable matrix for cell proliferation and attachment. However, the results have suggested that the novel nanofiber fabrication system would be very useful for the structure control of 3D nanofiber fabrics.

The objectives of the present study was to evaluate biological nitrogen fixation, P and K uptake ability of 31 soybean mutant lines (induced by Gamma irradiation) and their parent cultivar at greenhouse level. Initially, 10 Rhizobial isolates and strains were tested for infectiveness and symbiotic effectiveness using Leonard jars, and the strain Bradyrhizobium japonicum strain RS 152 was selected as the most efficient strain. The experiment was conducted under proper greenhouse condition with a randomized complete block design on a soil with no indigenous rhizobia and low nitrogen and phosphorus content. Thirty-one soybean mutant lines and two inoculated and un-inoculated wild cultivar blanks were replicated three times. Each pot contained 3.5 kg air-dried homogenized soil, and at the time of planting each seedling was inoculated with l mL of inoculum RS 152 containing approximately 9 × 10⁸ cells per mL. During about 4 months of growth, the plants were irrigated to maintain the soil moisture approximately 0.8 field capacity. The plants were harvested at the plant developmental stage of pod filling (R6), and several parameters, such as dry matter of shoot, nodule and roots, number of nodules, and proportion and amount of Nitrogen derived from air (Ndfa% and N-fixed) were measured. According to the results, in most parameters, the mutant lines were significantly different with each other and also with the L17 parent soybean cultivar. The mutant line 5 showed the maximum value of %Ndfa (73.068) compared to the cultivar L17 (48.762), indicating significant increase of biological nitrogen fixation, by about fifty percent, through physical mutagenesis. In addition, the mutant lines 21 and 31 had higher phosphorus and potassium uptake than the others, however, significant differences were observed for phosphorus uptake capacity compared to the cultivar L17. Although more detailed studies are needed to evaluate effects of these mutations on nitrogen fixation, macro- and microelements absorption capacity, and also on yield and quality parameters, these findings show that gamma irradiation could be helpful to induce new nutritional properties in soybean and release new mutant cultivars.

High pressure and temperature in earth crust lead to fracture and microcracks in rocks. Direct access to earth crust rocks at great depths is very costly and in most cases impossible. The study of the condition of rocks at great depths is often done using indirect methods such as seismic waves. The results of these studies are compared with the results of laboratory studies of wave velocities in different rocks and the conditions of the rocks are simulated. At high depths, hydrostatic stress is applied to the rocks of earth crust, and tectonic, earthquake and other stresses cause it to be anisotropic. The main purpose of this study is to investigate the change in compressive wave velocity due to change in compressive stress in rocks. In first, a cylindrical core of different stones with a length to diameter ratio of 2 to 2.5 is prepared according to the standard test method (ASTM D4543) and their dimensions and weight are determined. after measuring the unconfined compressive strength of cores according to standard test method (ASTM D2938), the hydrostatic pressure of 50% to 95% of it is applied to the rock samples prepared from the earth. This pressure is applied to the cores by using the Hoek cell (for lateral pressure) and the axial load machine and using ultrasonic device, determine the compressive wave velocity (ultrasonic pulse) is determined according to the standard test method (ASTM D2845) in the axial direction of the sample. Then, the wave velocity was measured during decreasing the lateral pressure (increasing deviatoric stress) in a stepwise manner, the wave velocity measured at each step. In the following, comparative diagrams of compressive wave velocity (V_p) with density (ρ_d), uniaxial compressive strength (UCS) and the effect of hydrostatic stress (σ_hyd) and deviatoric stress (σ_dev) on P-wave velocity in each sample are drawn. The results show linear relationships between compressive wave velocity and physical properties of rock samples, also the P-wave velocity at hydrostatic pressure is the highest and as the lateral pressure decreases (increasing the deviatoric stress), the velocity also decreases.
