Purpose: Clustering and co-word analysis is a method to reveal relationships and links and illustrate the intellectual structure of a scientific FIELD. This research tries to study the intellectual structure of articles in the FIELD of futures studies in Iran by using the technique of co-word analysis. Method: The current research is a descriptive-analytical development with a scientometric approach. The statistical population is 921 articles retrieved records in the FIELD of futures studies. Findings: The findings showed that articles in the FIELD of futures studies in Iran are often associated with positive growth, and in terms of frequency, the keywords scenario, Islamic Republic, and foresight are the most frequent in futures studies. The findings related to the hierarchical clustering led to the formation of 8 clusters in this FIELD, namely "ICT visions", "geographers who love the future", "knowledge development", " Futuristic higher education", "Future of Religion", "Regional Relations", "Strategic Foresight" and "Heavy Weight of Method". Conclusion: According to the findings of the current research and the high frequency of the keyword scenario, as well as the density and relationships of this keyword with other keywords, it can be concluded that the scenario is the dominant approach in futures studies. Also, according to the resulting clusters, it was observed that these researches have a high variety, but addressing the future in many areas is still neglected.

Four important ways of religious education in the FIELD of beliefs are inferred in this article through the nature of religion in the Holy Quran. We have examined two categories of “nature of religion” and “methods of religious education” for this purpose. All verses including the root of “د ـ ی ـ ن” (religion) have been investigated in order to properly understand the nature of religion in the Holy Quran. Then, we have benefited from the inference method to find the ways of religious education in the Holy Quran. In the inferential method, we have reached the “conclusion”, which is the method of religious education by using two premises, “normative” and “realistic”. The solutions of the Holy Quran to achieve the methods of religious education are explained in the following. For example, using the Scriptures directly to know the right actions is one of the solutions of the Holy Quran to reach the way of believing in the punishment of deeds. The achievement of religious education methods through discovering the nature of religion and explaining the purpose of education on the one hand and using the inferential method as a research method on the other hand is one of the innovations of this research. The achievements of this paper can be used to provide an educational theoretical model for formal and public education system.

We report the effect of external ELECTRIC FIELD (EEF) on the magnetic properties of MnxGe1-x, diluted magnetic semiconductor. We present a Kondo Lattice Model type Hamiltonian with exchange coupling between localized spins, itinerant holes and the EEF. The magnetization, the dispersion and critical temperature (Tc) are calculated for different values of EEF parameters (a) using double time temperature-dependent Green function formalism.The enhancement of the (Tc) with the EEF is shown to be very distinct and is in agreement with recent experimental observation and much required for spintronics applications and devices.

A common method for CONTROLling a group of parallel converters in decentralized CONTROL strategy structure in an island microgrid, the use is the droop-down characteristics of frequency ω-P and voltage E-Q. However, the problem with using this method is that the reactive power is not properly distributed (in proportion to the capacity of the micronutrients) between the micronutrients, which may lead to overload in the converters. Microgrids may also suffer from dynamic stability problems such as power fluctuations, which can be increased by switching between active and reactive power CONTROL. To avoid this problem, the X / R ratio of transmission lines is an important parameter that should be carefully considered in the design of micronutrient CONTROLlers. By linearizing and simplifying conditions, the CONTROL system conversion function model becomes a single input-single output system, which is efficient enough to show the relationship between CONTROL parameters such as slope of droop characteristics and derivative sentences, virtual impedance, and voltage CONTROLlers. Using this model, stability conditions for different parameters are analyzed. Also, to improve power distribution stability, common droop strategies are modified by adjusting the slope as well as adding nonlinear sentence sections. This approach reduces the coupling between active and reactive power CONTROL and reduces the dependence of power distribution on grid parameters such as the X / R ratio. To evaluate the reliability of the proposed model, the simulation results in a sample island microgrid in MATLAB software are presented.

Wheat ground beetle Zabrus tenebrioides (Goeze) (Coleoptera: Carabidae) is an important wheat pest in Iran and some regions of the world. This pest causes damage to wheat by feeding on the root, stalk, and leaves. Farmers try to CONTROL this pest by the foliar application of different insecticides, but this method causes damage to the environment. To find an effective method to CONTROL this pest, the thiamethoxam insecticide (Cruiser®) efficiency was evaluated using seed treatment in this study. An experiment based on a randomized complete block design with four treatments and four replications was conducted in a FIELD in Ramhormoz city, Khuzestan province (Iran). The treatments were 150 and 200 ml of thiamethoxam plus 2350 ml of water for seed treatment, 2,000 ppm of diazinon by FIELD spraying at the wheat tillering stage, and a CONTROL. The results indicated that the average plant density in 150 and 200 ml of thiamethoxam (333.58 and 333.28 plant/m2, respectively) was more than those of diazinon (258.28 plant/m2) and the CONTROL (182.12 plant/m2). The average ear density in 150 and 200 ml of thiamethoxam (513.78 and 506.12 plant/m2, respectively) was more than those of diazinon (321.22 plant/m2) and the CONTROL (260.86 plant/m2). According to the present results, farmers can use 150 ml of thiamethoxam plus 2350 ml of water for 100 kg of seeds to CONTROL this pest by seed treatment.

To evaluate the effect of nitrogen and water withholding in vegetative growth stage of corn on efficacy of nicosulfuron and 2,4-D+ MCPA an experiment was conducted as a factorial arrangement in a randomized complete block design with three replications at Tarbiat Modares University in 2017. The first factor contained four treatments including application of nicosulfuron, 2,4-D+ MCPA, weed free and weed infested as CONTROL. The second factor consisted of normal irrigation and water withholding from 4 to 8 leaf stage. Third factor contained either urea application or no fertilizer application. Normal irrigation and nitrogen fertilizer application significantly increased nicosulfuron and 2,4-D+ MCPA efficacy in weed CONTROL and total weed dry weight decreased to 341 and 361 g.m-2 respectively compared 1370 g.m-2 as weed infested. Nicosulfuron and 2,4-D+ MCPA reduced weed total dry weight significantly under irrigation withholding. Grain yield increased with application of nitrogen and nicosulfuron. Grain yield was higher with application of 2,4-D+ MCPA than nicosulfuron without nitrogen application under irrigation withholding. Application of nicosulfuron with nitrogen application provided satisfactory weed CONTROL and increased grain yield.

Objective: The present study was conducted with the aim of effective school-based self-CONTROL skill training on increasing psychological hardiness and self-efficacy of male students of the first secondary level.Method: This research is a semi-experimental study with a pre-test-post-test design with a CONTROL group. The statistical population of the present study included male students of the first secondary school in Qom city, 30 students were selected using the available sampling method and divided into two groups of 15 people completely randomly. Students in the experimental group participated in 8 sessions of the school-based self-CONTROL training program, and the CONTROL group did not receive training. Before and after the implementation of the intervention, both groups were evaluated using the psychological hardiness scale of Lang and Goulet (2003) and the self-efficacy scale of children and adolescents (SEQ-C). The data was analyzed using spss-22 software and through repeated measures analysis of variance test.Findings: The results showed that school-based self-CONTROL skill training has a significant effect on increasing students' psychological hardiness and self-efficacy (P<0.01). Conclusion: The findings of the present study indicated that school-based self-CONTROL skill training can be an effective intervention in increasing psychological hardiness and self-efficacy in students.

To investigate the effect of weed interference and weed-free periods on Balangu (Lallemantia royleana Benth. in Wall) and to evaluate the critical period of weed CONTROL (CPWC) in this oilseed crop, an experiment was conducted as a randomized complete block design with three replications in Naghadeh region in 2018. Experimental consisted of two groups of treatments; weed infestation treatments (infestation for 144.2, 345.9, 574, 848.2, 1147.6 and 1451.3 growing degree day (GDD) after transplanting and then plots were remained weed-free the rest of the growing season) and weed-free treatments (weeding for 144.2, 345.9, 574, 848.2, 1147.6 and 1451.3 GDD after transplanting and then plots were remained infested until harvesting time). In each block, one weed free and weed infested CONTROL was for all the growing season. Results indicated that the density and dry biomass of weeds were increased as weed removal was delayed. In contrast, density and dry biomass of weeds were decreased as weeds establishment was delayed. Height, tetrachenes fruits, ripened achenes, 1000-seed weight and biological, seed and relative yields of Balangu were decreased and increased as the duration of weed-infested and weed-free period increased, respectively. Also, logistic and Gompertz curves fitted to data showed that the beginning and end of the CPWC based on a 10% yield loss of relative yield, was estimated to be from 11 to 108 days after transplanting (97 days weed-free period) in order to prevent a noticeable yield loss.

The study investigates the ELECTRIC FIELD and space charge distributions in propylene carbonate under direct current (DC) applied FIELDs using Kerr effect. Propylene carbonate is known for its high permittivity and is utilised in many applications, including electrochemical systems and diELECTRIC materials. Understanding the behaviour of ELECTRIC FIELDs and space charge distributions within propylene carbonate is critical for optimising its performance in these applications. In the study, Kerr effect is employed which by applying the DC ELECTRIC FIELD across the test liquid for measuring the ELECTRIC FIELD and space charge distributions within the propylene carbonate. The experimental setup involved a CONTROLled application of DC FIELDs, and the Kerr effect measurements were conducted using an optical system. The results show significant understandings into the behaviour of space charges and their influence on the ELECTRIC FIELD distribution in propylene carbonate. Distinct patterns of charge accumulation and ELECTRIC FIELD distortion were observed and analysed in the diELECTRIC liquid properties and charge transport mechanisms. The relationship between ELECTRIC FIELDs and space charges in propylene carbonate under DC conditions has been provided by the findings. The study also shows that the Kerr effect is a useful tool for studying ELECTRIC FIELD distributions in complex materials.
