    The ministry organization as a symbol of Iranian sreaming is the important element in Iranian historiography. Reproduction of many of Iranshahri thoughts teachings in Seljuk\u27s period provided background for note historians to ministry organization. With the domination of Turks on Iran was established ministry s status until free rulers of the art of government benefit of ministry\u27s knowledge. Ravandi was one of the important historians in Seljuk\u27s period. However, he extracted his historical narratives from Saljuknameh, but with the completion of them with other sources and analyzing of dates. His book was changed to an important source with a different style. Ministry organization was High-Frequency concept in Ravandi historiography. His historiography has been set as useful epistle for express reasons. The ministry in his historiography was a symbol of foresight that was a cause of stable government. This article is going to enter a descriptive and analytical methodology to analyzed Ravandi\u27s approach to ministerial organization and answered to these questions what impact of ministry status on Seljuk\u27s period in Ravandi\u27s historiography? And this approach has been influenced by what factors shape

    [EN] In this paper, we study the class of simple dynamical systems on R induced by continuous maps having finitely many non-ordinary points. We characterize this class using labeled digraphs and dynamically independent sets. In fact, we classify dynamical systems up to their number of non-ordinary points. In particular, we discuss about the class of continuous maps having unique non-ordinary point, and the class of continuous maps having exactly two non-ordinary points.The author is very thankful to the referee for giving valuable suggestions.

    Abstract Background Over the years, nanoparticles have emerged as a promising approach for improving crop growth, yield, and overall agricultural sustainability. However, there has been growing concern about the potential adverse effects of nanoparticles in the agricultural sector and the environment. The present study aimed to investigate the detrimental effects of high (1000 mg L−1) concentrations of copper oxide nanoparticles (CuO NPs) on barley seedlings. The equivalent concentrations of CuO bulk and the ionic form of copper were also used in the experiments for comparative analysis. CuO NPs were characterized by Field Emission-Scanning Electron Microscopy, Dynamic Light Scattering, Zeta Potential analysis, and X-ray Diffraction prior to the application. Barley seedlings were subjected to the foliar application of CuO NP, CuO bulk, ionic Cu, and control group. The presence of CuO NPs in barley leaves was confirmed 72 hours after treatment by energy-dispersive X-ray analysis. Results The results showed a CuO NPs treatment led to an impairment of nutrient balance in barley leaves. An increase in hydrogen peroxide content followed by the higher specific activity of catalase and ascorbate peroxidase was also observed in response to CuO NPs, CuO bulk, and Cu2+ ions. The profile of phytohormones including auxins (IAA and IBA), Gibberellins (GA1, GA4, and GA9), abscisic acid (ABA), ethylene (ET), and jasmonic acid (JA) significantly affected by CuO NPs, CuO bulk, and Cu2+ ions. The transcripts of the PR1 gene involved in systemic acquired resistance (SAR) and LOX-1 and PAL involved in induced systemic resistance (ISR) were significantly upregulated in response to CuO NPs treatment. Conclusion Our findings suggest that the systemic resistances in barley seedlings were induced by higher accumulation of ABA, ET, and JA under CuO NPs treatment. The activation of systemic resistances indicated the involvement of both SAR and SAR pathways in the response to CuO NPs in barley

    No full text
    Our world is shrinking because of computerized linkages and the mobility of society. Information is shared rapidly around the world. Issues surrounding newborn and infant nursing are global. In efforts to acknowledge the international community, each Newborn and Infant Nursing Review issue will feature a column that highlights care-related issues from a featured country or region of the world. This article focuses on Pakistan. Newborn and infant health issues are global ones. To review issues occurring in different areas of the world, a different area of the globe will be featured that addresses Newborn and Infant Nursing Review\u27s theme-oriented topic. This month, Pakistan will be featured. Our guest author is Ms Shela Akbar Ali Hirani, MScN, BScN, and Regional Network Contact for the Council of International Neonatal Nurses for Pakistan. This month\u27s article focuses on the effects of humanitarian emergencies on infants\u27 health

    Among the most common illnesses affecting people’s lives are skin disorders, for which a variety of therapeutic approaches has been suggested. Traditional herbal remedies can be counted among the best therapies for such diseases. Herbal shops, or “attaris” (in Persian), play a major role in the traditional therapy of each region. This study investigated the medicinal plants commonly prescribed and traded in herbal shops of Jahrom, Iran, to cure skin diseases. Ethnomedicinal data were collected using the snowball method for 38 plant species belonging to 34 families. A semi-structured questionnaire was used to collect information from herbal shops. Asteraceae, with five species, was the most dominant medicinal family of the prescribed plants, and the fruits, seeds, and leaves of plants are the parts most used. Herbal mask (36%) was the most common mode of herbal drug preparation. The medicinal herbs prescribed by herbal healers are often used for the treatment of acne (36%) as well as for strengthening, clarifying, and giving freshness to the skin (26%). These medicinal plants may be candidates for the development of novel herbal skincare products. The findings of this research revealed that the herbal healers of Jahrom have an outstanding knowledge of traditional treatments for skin diseases.Entre las enfermedades más comunes que afectan a la vida de las personas se encuentran los trastornos de la piel, para los que se han sugerido diversos enfoques terapéuticos. Los remedios tradicionales a base de plantas pueden contarse entre las mejores terapias para estas enfermedades. Las herboristerías, o “attaris” (en persa), juegan un papel importante en la terapia tradicional de cada región. En este estudio se inventariaron las plantas medicinales comúnmente recetadas y comercializadas en las herboristerías de Jahrom, Irán, para curar enfermedades de la piel. Los datos etnomedicinales se recolectaron mediante el método de bola de nieve para 38 especies de plantas pertenecientes a 34 familias. Se utilizó un cuestionario semiestructurado para recolectar información de las herboristerías. Las Asteraceae, con cinco especies, fueron la familia botánica más citada, y los frutos, semillas y hojas de las plantas fueron las partes más utilizadas. La mascarilla a base de plantas (36%) fue la forma más común de preparación. Las plantas medicinales prescritas por los curanderos se utilizan a menudo para el tratamiento del acné (36%), así como para fortalecer, aclarar y dar frescura a la piel (26%). Estas especies pueden ser candidatas para el desarrollo de nuevos productos a base de plantas para el cuidado de la piel. Los resultados de esta investigación revelaron que los curanderos de Jahrom tienen un elevado conocimiento de los tratamientos tradicionales para las enfermedades de la piel
