Considering the importance of solidarity as a theoretical and political structure and its connection with social harmony, acceptability and political legitimacy, the present research has conceptualized and formulated the PROBLEM of solidarity in the context of Iran's multi-ethnic society through the mediation of existing studies. . In the current research, the hybrid method has been used. The sample and statistical population of the research includes selected qualitative studies that have investigated the issue of solidarity and its dimensions in Iran from different aspects and perspectives in the period from 1372 to 1398. After searching in different databases, 500 related articles, books and research reports were identified and finally 54 sources were selected to perform the meta-combination method. Based on the synthesis of studies, solidarity in the multi-ethnic society of Iran has found a PROBLEMatic situation. The results of the research confirm that the coordinates of solidarity in Iranian society are based on structural contexts and conditions. The main field in which the issue of solidarity in Iran should be established is the acceptance of a reality called "reliability and stability of cultural diversity". Based on the meta-combination of studies, the coordinates of solidarity in Iran's multi-ethnic society, due to "intercultural affinities", "disruption and non-inclusion in ethnic policies", "instability and imbalance of development", "inefficiency of ethnic political management" and "identification disorder". In the meantime, "cultural globalization", "taking role models from ethnic elites", "geopolitics of ethnic areas and transnational interventions" and "ethnic extension" are considered as intervening conditions. Despite the fact that ethnic and religious diversity is recognized as a central sign in the constitution, with this definition, political agents have sometimes resorted to strategies that social suffering and extroversion has formed in ethnic communities.

The PROBLEM of personal identity among others may stem from the following question—what does be the person that you are, from one day to the next, necessarily consist of? The diachronic PROBLEM of personal identity raises question on the necessary and sufficient conditions for the identity of the person over time. The synchronic PROBLEM is grounded in the question of what features or traits characterize a given person at one time. To answer these questions, John Locke discarded the soul and the body as necessary and sufficient substances for personal identity over time. He accepted consciousness as the only criterion for personal identity; the only thing capable of remaining the same and preserving personal identity through change. Though Locke’s argument is somewhat clear and coherent but what remains vague and incoherent is embedded in the question—what exactly is consciousness? How and why should it be the basis or criterion for the determination of personal identity? Using the method of critical analysis, I argue that Locke’s choice of consciousness as the determinant of personal identity, though quite novel, is incoherent and vague. Secondly, Locke had already presumed and anticipated clearly though fallaciously the very thing he wishes to substantiate. I therefore conclude that Locke’s argument is just another way of trying to escape but inadvertently prolonging the difficulty of apparently articulating a distinction between the psychological approach and physiological approach to the PROBLEM of personal identity. However, in my submission, I propose the concept of the “other” as alternative approach— a sort of an extrinsic-intrinsic approach to the PROBLEM of personal identity.

In Kant and the PROBLEM of Metaphysics (KPM), Heidegger shows how the initial image-making power of the imagination is pictorial in the pure image of time. He further clarifies the recognized link between the syntheses and the time-visualizing power of images which is pictorial formative power, which can visualize time. The three syntheses of imagination are replaced with the modes of existence of Dasein. Three kinds of photographs resemble the images produced when the transcendental imagination functions as Dasein. We can address the ways to visualize time by considering Dasein with a photographic preoccupation through 1. A possible look in the form of presentation (a photograph shows an immediate look of a house or person as intuitable this-here); 2. An immediate look of the thing, house, or deceased person, as well as a copy or its reproduction as a death mask; and, 3. The manner of contemplation of a likeness is an immediate look of a being present in the form of representation.

Considering the adverse effects of storage insect pests and their resistance to chemical insecticides, identifying safe, cost-effective, and durable methods to control and reduce storage pest-induced damage appears essential. Utilizing diatomaceous earth is one alternative to chemical pesticides for controlling stored-product insect pests. This study evaluated the insecticidal activity of diatomaceous earth at a concentration of 0.2 mg/cm2 against two stored-products insect pests, Rhyzopertha dominica F. and Tribolium confusum Jacqulin Duval, on concrete, mosaic, and galvanized steel surfaces. To this end, the surfaces were treated with different diatomaceous earth FORMULATIONs, including a commercial FORMULATION, SilicoSec®, an Iranian FORMULATION, Dryasil, Dryasil + 0.05% Mentha longifolia L. extract, and talcum powder + 0.05% M. longifolia extract. Mortality was measured 1, 3, 5, and 7 days after treatment. The experiment was conducted at 27 ± 1 °C, 60 ± 5% relative humidity, and dark conditions. The experiments were performed in nine replications (10 adults in each replication). The mortality percentage of R. dominica 7 days after treatment with Silicosec®, Dryasil alone, Dryasil + 0.05% M. longifolia extract, and talcum powder + 0.05% M. longifolia extract on galvanized steel were 43.33, 54.44, 33.33, and 25.55%, respectively. The results indicated that the mortality percentage of T. confusum on galvanized steel was 35.55, 45.55, 26.66, and 23.33%, respectively. The mortality of T. confusum was lower than that of R. dominica adults. Results indicated that the insecticidal effect of diatomaceous earth increased over time. Diatomaceous earth alone had a more significant insecticidal effect than combining them with M. longifolia extract. The highest percentage of mortality in all treatments was found on the galvanized steel, mosaic, followed by concrete surfaces, respectively. Therefore, Dryasil FORMULATION can be used to control stored-products pests in grain silos, although its insecticidal efficacy varies based on surface type

The influential physicist Richard Feynman became interested in the relationship between religion and science during a mid-career phase. He proposed that their interface was embroiled in unresolvable difficulties. He felt that science demanded an attitude of uncertainty for its claims, while religion contrarily required certain belief in its core doctrines. Though possessing several non-contradictory dimensions, Feynman felt that the nature of the truth claims of science and religion suffered from insurmountable elemental conflicts. This was by contrast to Karl Popper, the leading critical rationalist of the 20th century, who argued that there could be no tension between science and religion. This paper will argue that the ‘Feynman PROBLEM’ is not as insoluble as it appears. Rather, several solutions exist within critical rationalism. Two will be presented-the first revolves around the conjectural basis of knowledge and is already a well characterised critical rationalist notion. The second is a novel solution based on the separate categorisation of psychological, pragmatic, and epistemological attitudes to religion and science. Karl Popper’s view of religion-science dissimilarity was a minimalist point of departure for critical rationalists, who have developed increasingly sophisticated frameworks for investigating the relationship between faith and reason. Critical rationalism represents an equally inspirational methodology for the pursuit of scientific and religious truth. Though both Feynman and Popper’s views on religion were underdeveloped, they foreshadowed the religion-science frameworks advocated by many late 20th century scientists, especially in the form of New Atheism and Gould’s NOMA theory.

Many tubular joints commonly found in offshore jacket structures are multi-planar. Investigating the effect of loaded out-of-plane braces on the values of the stress concentration factor (SCF) in offshore tubular joints has been the objective of numerous research works. However, due to the diversity of joint types and loading conditions, several quite important cases still exist that have not been studied thoroughly. Among them are internally ring-stiffened multi-planar XT-joints subjected to axial loading. In the present research, data extracted from the stress analysis of 81 finite element (FE) models, verified using experimental test results, was used to study the effects of geometrical parameters on the chord-side SCFs in multi-planar tubular XT-joints reinforced with internal ring stiffeners subjected to two types of axial loading. Parametric FE study was followed by a set of the nonlinear regression analyses to develop four new SCF parametric equations for the fatigue analysis and design of axially loaded multi-planar XT-joints reinforced with internal ring stiffeners.

The aim of the current research was to identify the characteristics of the four elements in order to provide a PROBLEM-oriented curriculum model in the elementary school mathematics course. There were 19 participants and the sampling was done purposefully. The data collection tools are semi-structured interviews and questionnaires. The PROBLEM-oriented curriculum template was designed using the characteristics of the elements and with the method of qualitative content analysis in the elementary school mathematics course. The identified features were validated by fuzzy Delphi method and Shannon's entropy method was used for data processing. Based on the results of the analysis, 7 main categories including the characteristics of goals at three levels of cognitive, attitudinal, skill, content, evaluation, teaching-learning strategy and 46 sub-categories were identified.                                                                                                                                                                In the fuzzy Delphi section, all features were confirmed by obtaining a de-fuzzified value greater than 0.7. The results of Shannon's entropy determined that the characteristics of starting teaching with a challenging question, creating a suitable educational environment, continuously monitoring the quality of learning strategies and communicating with students' talents have attracted the most attention and obtained the highest ranks and had a higher importance factor than other characteristics

The Islamic Republic of Iran’ s Broadcasting (IRIB) is the main and most official mass media in the Islamic Republic of Iran. Thus, it has a special position, and it is necessary to monitor the proper and transcendent measures of this institution. According to the constitution, an external oversight mechanism has been established for it, focusing on the Broadcasting Supervisory Council (BSC) of the IRIB. Therefore, it is necessary to evaluate the perfor-mance of the BSC. This research aimed to discover issues and disadvantages related to the performance of the BSC. For this purpose, we conducted a thematic analysis of 13 interviews with the relevant experts. Eventually, 5 integrated codes representing the issues and risks of the council have been formulated. These codes included the following: council legal PROBLEMs; structural and financial weakness of the council; supervisory issues; weakness of council members, as well as legal PROBLEMs and complexity in IRIB.

Using fossil fuels in transportation sector has caused many environmental and economic PROBLEMs. Therefore, the use of alternative fuel vehicles is necessary. Since such vehicles have limited fuel tank capacities, hence, frequent refueling is required. Regarding the possibility of the existence of different fuel costs in various refueling stations, the selection of suitable stations with the purpose of minimizing total cost of refueling is important. Moreover, minimizing the number of refuelings could be considered as another important criterion in refueling operations of a given trip. In this paper an integer bi-objective model is proposed to select suitable refueling stations considering two criteria of minimizing the total cost of refueling and minimizing the number of refuelings. To solve the proposed model, a new algorithm is suggested and its performance is compared with the weighted sum method of multi-objective optimization literature. The results show the superiority of the proposed solution approach.
