In sacred text of the religion of Yari, we are confronted with some emphasized moral principles which have been stated by the great men of this religion repeatedly. These moral principles are honesty, purity, inexistence and RADA. This article attempts to study the root of the term of RADA in Yaresan literature. It specifies that the term RADA in Yaresan literature which means donation, generosity and bounty is the same with Rata in Avesta and Zoroastrianism; because Rata in Zoroastrianism is the god of generosity and bounty, and it is also considered as a moral criterion in this religion. The only difference between these two terms is in the phonemes "d" and "t" that is considered as a general rule among the rules of the phonemes transformation.

In this study, four sand dunes, in the East of Babolsar were studied. These dunes are of lunar parabolic type. Their sediment textures are sand and sand with little gravel;.these sediments are moderately sorted, leptokurtic and have positive skewness. More than 60 percent of these deposits are composed of metamorphic and igneous rock fragments. Three sedimentary facies (i.e. A, B1 and B2) were recognized; facies A and B2 show charactertistics of coastal plains and sand dunes; facies B1 were deposited in a swash zone. The age of the middle and lower part of the studied dunes varies from 14 to 25 ka; indicating the minimum and maximum depositional rate of 0.15 and 0.2 mm/y, respectively. Four RADAr Facies were recognized; their characteristics are indicative of dune foreslope, cut and trough fill and swash zone.

Let A be a Banach algebra with Jacobson radical RADA and d a continuous derivation of A. The purpose of this article is to investigate some sufficient conditions under which d(A) ⊆ RADA from a topological point of view. Interesting results are established with some applications.

RADA 16-I is a synthetic amphiphilic nanopeptide which is designed to self-assemble in a controlled way into fibrils and higher ordered structures, depending on solvent condition. This peptide has many applications in tissue engineering and wound healing. We have studied the interaction of four RADA 16-I chains into a cluster formation in the presence of 0.2 M sodium chloride, using all-atom molecular dynamics simulation. Several independent 20 nanosecond simulations were performed. They showed that the fastest first nucleation step occurred in the presence of 0.2 M sodium chloride, compared to water. It is also found that salt has significant effect on the compactness and secondary structure of this peptide. In fact sodium chloride helps each peptide to adopt transitional expanded α-helix conformation in order to induce better interaction sites for the self-assembly. The results give insight into the effect of ionic strength on self-assembly mechanism of RADA 16-I in the bulk solution.

Many Western thinkers believe that the Qur'an has a discrete content, but some thinkers reject this belief and try to prove the structural integrity of the Qur'an text. "Nevin Reda", a contemporary Quranic scholar, discusses. Because among the structural and content division of the Qur'anic surahs such as bowings and prostrations, Reda's structural method distinguishes itself in a systematic way in such a way that Reda discusses the two structures of linear and circular composition in Surah Al-Imran: He divides the entire parts of Surah Al-Imran into It is divided into three parts in terms of subject, each of which has its own sub-topic which will be expressed in circular or thematic composition. He explores each of the three parts of the surah in terms of linear and literal composition. Therefore, in a structural way, it provides the possibility of rejecting the problems of Orientalists on the high wall of civil society like Al-Imran. At the same time, there are some methodological flaws in the division of Reda, such as ignoring some topics and words that could help to better understand the structure and content. In addition, Reda does not consider the repetition of key words in the surah and does not mention some words in the sections where they are repeated. This indicates the need for more accuracy in the analysis and interpretation of the text of the Qur'an and emphasizes the importance of carefully examining the basis of the division before presenting the interpretation.

‎Cruz‎, ‎Monsalve and RADA [Extremal values of vertex-degree-based topological indices of chemical trees‎, ‎Appl‎. ‎Math‎. ‎Comput‎. ‎380 (2020) 125281] posed an open problem to find the maximum value of the exponential second Zagreb index for chemical trees of given order‎. ‎In this paper‎, ‎we solve the open problem completely‎.

In this paper, the Range Doppler algorithm (RDA) for synthetic aperture RADAr moving on a ballistic trajectory is presented. The 3-dimensional acceleration and non-uniform trajectory cause decreases in efficiency of conventional imaging algorithms. Therefore RDA provided must be consistent with the acceleration and velocity parameters. Based on 2-dimensional frequency domain expression and ballistic trajectory, the Range Doppler algorithm is presented. To evaluateion the proposed algorithm for the single-point target, SAR image is simulated based on ballistic trajectory simulated and quality parameters of simulation results are computed. For To investigated the capability of the proposed algorithm for extensive targets, SAR image is extracted by consideration of 5 point targets and 17 point targets extracted. The simulation results show the validity of the proposed algorithm in extracting RADA images not withstanding 3-dimensional acceleration and ballistic trajectory.

Historia Gothica and Historia Arabum written by the Spanish prominent bishop, Rodrigo Jimenez de RADA, are of the most outstanding medieval historical works. Historia Arabum is the first Western work on Islamic history due to attention to Islamic history, which led to the importance of Rodrigo Jimenez among historians. The main question of the article is to what extent Islamic sources have influenced the written histories of medieval Spain? This article tries to find out the extent of Rodrigo's reliance on Islamic sources by the comparative study of Rodrigo's works and Islamic texts. Historia Gothica also has interesting points about the Arab attack to Spain, which helped a lot in correcting the information of medieval Europe about the fall of Spain. The information in both of Rodrigo's works about the events of the Middle East and the Islamic world until the 13th AD century is surprisingly different from the stereotypical information found in Latin histories before itself and contains new and important points.

Long-standing concerns about the feeding needs of infants and the search for a viable alternative to the formula prompted the World Health Organization to propose the concept of breast milk banks in 1909. A year later, the first donor milk bank was founded in Boston, Massachusetts to be followed by similar institutions in various countries in Europe and Asia. Multiple births and mothers’ inability to produce adequate breast milk, premature births resulting in mothers’ insufficient milk supply, babies’ reaction to the chemical composition of their mothers’ milk and several other reasons have triggered an increase in the demand for breast milk banks. An examination of the arguments related to RADA or milk-kinship in Shitte and Sunni jurisprudential and narrative sources demonstrates that there is no judiciary challenge or obstacle to establishing breast milk banks in Iran and other Muslim countries. This descriptive-analytic study uses library sources to investigate the evidence and confirming principles of milk-kinship in order to support the above-mentioned concept.
