Review : The ethical nature of the search is one of the most important ethical issues for the general public, and especially for those whose job descriptions are related to the investigation, such as law enforcement, security, intelligence, journalists and news. Searching means reading, checking, searching and getting information. An investigation into the investigation of the hidden and hidden affairs of others, which has a personal and individual nature. Therefore, the use of the term "exploration" in cases of apparent and obvious nature or, in other words, social and collective nature, is not correct. There are three separate types of searches: separate searches, social security surveys, and affairs in enemy affairs. Exploration of the personal affairs of individuals is not permissible by reason of the wisdom and explicit verse of "Vlattjisso" and many narratives. The search for social affairs, a better term for "inspection" and "supervision", is permissible and, in some circumstances, obligatory for rational reasons and some narratives. Knowledge of the community, the needs and demands of the people, and the establishment of social justice, which is one of the most important tasks of the ruling ruling Islamic state, as well as their achievement, largely depends on the choice of officials, government officials, believers and specialist, needs to investigate the functioning of the device And social organizations.

The knowledge of modern linguistics and the collation of literary texts, which linguists refer to as "critical discourse from the point of view of semantic semiotics", is the science in which the collator of writing seeks a deep understanding of the various layers of thought and the atmosphere of composition. The texts go beyond the sentences and the context of the speech according to the artistic position and its position is linguistically explored and reveals the metatextual vision of the writer or the songwriter.Therefore, the author of the present research explores the hidden message in the linguistic layers of the three beginnings in the most precious epic masterpiece of the Persian language, Shahnameh with the  following titles: "In the name of God" , the tragic poems "Rostam and Sohrab" and "Rostam and Esfandiar" in  a descriptive-analytical method to explore the critical discourse.

Religion and mysticism have affected the human life for long. Within the last few centuries, the supplementary and critical out looks of the experts to these issues have been led to establishing specific fields at universities and some researchers have considered them. These theories should be applied more efficiently in order to determine their accuracy and reliability. Based on Sween Bern’s theory, the mystical experiences of the mystics are classified in five groups.            Since Hafiz has been recognized as one of the most prominent Iranian figures in mysticism. In this research, the Sween Bern’s theory has been applied to extract and classify the mystical experiences from Hafiz Divan. The findings of this research indicate that the considered mystical experiences in Hafiz Divan are placed in the frame of Sween Bern’s theory. However, few points need to be explained        Manuscript profile

In order to meet the significantly increased metal demand of the world market, it has been decided to expand the capacity of the existing alumina refineries and to set up new plants (more than 2 Mt/a each). The selection among the bauxite sources is based on previous exploration data, such as: tonnage, grade, mineralogy, etc., the geographical position of the deposit, existing natural and constructed infrastructure and the distance from deep water ports. Environmental and political risks are also investigated. Decision making is a complex task in which the close co-operation of professionals of the bauxite-alumina industry is needed. The authors specify the most determinant factors which are investigated for decision making and call attention to the fact that, in many cases, inconsistent data are compared as if they were equal in value or identical such as: the reliability of explorations made for deposits in various countries, and at different times is also different, the methods applied in reserve calculation and resource estimate are different, the qualitative criteria used for commercial grade ores are different, no numeric data are available showing the possible error in reserve calculation the terminology used for bauxite categories is also different.Adequate attention is never given for the further development of possible prospects; their investigation may be neglected in the selection. As a consequence, when different resources are compared, the geological risks (stability in bauxite production) cannot adequately be taken into account. For minimizing the transport costs (either the bauxite supply to the alumina plant or the alumina shipping to the smelter or both) the geographical position of the raw material is one of the most significant economic factors in the value of the deposit. There are several regions in the world which are so rich in bauxite potential (West Africa, edge of the Guyana Shield in Venezuela and Brazil, the Amazon Basin in Brazil, Weipa Gove in Australia, Eastern Ghats in India, etc.) where new deposits should be explored as a function of their geographical position. The landsat interpretation has proved to be an excellent tool for establishing priorities among the options. The authors give a short review and comparison of the most significant regions and deposits focusing their interests on the: tonnage, grade and mineralogy, further prospects (undiscovered) deposits, infrastructure, distance from mine/deposits to the deep water ports, available alumina content (for a low or a high temperature procedure) for estimating the bauxite consumption per ton of alumina, soluble silica content for estimating the caustic soda consumption per ton of alumina, beneficiation cost in some cases, risk factors (geological, environmental, political and national) The authors conclude, that in spite of the fact that about 30 - 35 billion tons of bauxite have been registered so far as proved + probable reserves and a further 55 – 60 billion tons can be estimated as possible resources in the world, finding new resources in better geographical locations and their exploration may be advantageous. The new exploration data must be more reliable, as well. The costs of reconnaissance and exploration may be far below the haulage costs. Manuscript profile

The Tareek Darreh gold deposit is located 40km north of Torbat-e Jaam in the Khorassan-Razavi province, NE-Iran. The study area mainly comprises slightly metamorphosed, sedimentary rocks of Jurassic age including alternation of shale, siltstone, and sandstone. These rocks have been intruded by plutonic rocks such as gabbro-norite, diorite, quartz-diorite, and rhyodacite. The ore bodes are exposed by trenching and pitting .In this study, all trenches and pits were systematically sampled and analysed by XRF, XRD, and ICP methods as well as petrological mineralogical studies. The alteration minerals of quartz, chlorite, albite, and sericite are mostly observed on the top or margin of the stocks. Alteration is more intensive at the contacts of the stocks where vein type mineralization has occurred. The veins are mainly composed of silica type and calcite type, arsenopyrite, chalcopyrite, and pyrite main ore minerals. Four promising mineralization zones were selected for further studies. The analytical results for the zones No. 2 and No. 4 confirm high gold, copper, bismuth, tellurium, and silver. In zone No. 2 (50 x 80 m2) an average of 3.5ppm gold was recorded for one of the trenches, while in zone No. 4 (50 x 250m2) the average gold content is 1.35ppm. According to our studies, The Tareek Darreh gold deposit is considered to be similar to the \"intrusion-related gold systems\". Manuscript profile

se: This research aimed to determine the effectiveness of intervention based on the exploration of remarriage families’ problems on child's relationship with stepparents. Methodology: This study was semi-experimental with a pretest and posttest design with control group. The research population was all remarriage families of Khorramabad city in 2019 year. The research sample was 20 families who after investigated the inclusion criteria were selected by purposive sampling method and randomly replaced into two equal groups (10 families in each group). The experimental group underwent 12 sessions of 2 hours (two sessions per week) based on an intervention based on the exploration of remarriage families’ problems and the control group did not receive any training. Data were collected by the demographic information form and parent-adolescent conflict scale (Prinz and et al, 1979) and analyzed by methods of independent t-test and univariate analysis of covariance in SPSS-26 software. Findings: The result of t test showed that the experimental and control groups in the pretest stage have not significant difference in terms of child's relationship with stepparents (P>0.05), but in the posttest stage have significant difference (p < 0/05). The results of analysis of covariance test showed that the intervention based on the exploration of remarriage families’ problems led to significant improved child's relationship with stepparents (p < 0.001). Conclusion: Considering the effectiveness of intervention based on the exploration of remarriage families’ problems on improving child's relationship with stepparents, the use of this method along with other educational and therapeutic methods is necessary to improve the child's relationship with stepparents. As a result, health professionals and therapists can use an intervention based on the exploration of remarriage families’ problems to improve psychological characteristics such as child's relationship with stepparents.

Background & Aim:Cognitive impairment is one of the age-related mental problems and a typical indicator of neurodegeneration. Eragrostis tremula Hochst. ex Steud. is a commonly used medicinal plant in Nigeria for memory enhancement. This study, therefore, aimed at evaluating the memory-enhancing potential of aqueous ethanolic extract of E. tremula in mice. Experimental: Classes of phytochemicals present in the extract were determined using standard protocol while its oral median lethal dose (LD50) in mice was estimated. The effect of E. tremula extract (125, 250 and 500 mg/kg) on learning and memory was evaluated in mice using behavioural paradigms: elevated plus maze (EPM), novel object recognition and Barnes maze. Open field and hole-board tests were also carried out to evaluate locomotion. Results: The phytochemical constituents of E. tremula were alkaloids, cardiac glycosides, flavonoids, tannins, saponins, steroids and triterpenes. Oral LD50 was estimated to be >5000 mg/kg. E. tremula extract significantly (P<0.05) decreased the transfer latency of mice during the retention phase of EPM test. In the novel object recognition test, it significantly (P<0.05) increased the discrimination index. In Barnes maze test, the extract significantly (P<0.05) decreased the mean primary errors during the acquisition trials. It also significantly (P<0.05) decreased the primary latency, primary error and increased the time spent in the target quadrant during the probe trial. E. tremula extract significantly (P<0.05) decreased the immobility time of mice in an open field at 250 mg/kg, while in the hole-board test, it significantly (P<0.05) increased the mean head-dip of mice at 125 mg/kg when compared to the negative control. Recommended applications/industries: The ethanol extract of E. tremula possesses memory enhancing properties which can be utilized in the management of amnesia and cognitive deficit.

Hence Health and cure services as one of main components of development has been created in line with society needs and their improvement. Purposes of this study is to investigate spatial system damages and locating pattern of cure and health land uses across 22- region on Tehran city. The present research is implicational and analytic- descriptive method has been used. Library and field studies have been used to collect data. ArcGIS program has been used to analyze data so that it can provide better locating based on the population of under investigation region and the way of accessing to clinical – health services. Therefore, the findings of the research show there are much differences among urban regions regarding accessibilities to health and clininical indices from one hand, lach of good planning for health land use in 22- region in Tehran and lack of spatial equibilium and accessibilities for regions which are uneven from the other hand. So, it is necessary to pay much attention to decrease of differences in clinical and health services of urban regions. Therefore, applied strategies are presented to get out of these problem in order to improve the condition and distribution of clinics in the different regions. Manuscript profile
