Investigating and Analyzing the Linguistic Structure and Classification of Khaghani's Short Poems

Poetic forms play an essential role in the division of Persian poetry. Most of the definitions of these forms refer to its form, and since in the sixth century some themes are expanding, and the form of lyric poetry has also become popular. In the works of poets such as Sanai and Khaghani, who are both poets and lyricists, the issue of classifying poems in the field of content and format has arisen. In the present study, we have examined and classified Khaghani's short poems from a linguistic point of view. We have concluded that due to the three linguistic, as well as "vocabulary selection", part of Khaghani's short poems are in the lyric poems and part of the lyric poems are in the short poems. Khaqani's short poems can be divided into 7 groups: 1. Poems all praise, 2. Poems of incomplete poems, 3. Grief poems, 4. Syntactic poems, 5. Judicial poems (advice), 6. Complaining poems, 7. Qalandari's poems. The linguistic features of some of these poems are very close to the form of "sonnets" in such a way that both very similar examples can be shown in both sonnets and poems. Khaghani is one of the poets who injected the sound of "praise" into the lyric after Sanai, and is the first poet to recite "mourning" in the form of a lyric. As a result, the line between short poems and lyric poems has blurred, making it difficult to classify his poems

کارکردهای تربیتی خودکنترلی و نقش آن در سلامت روان از دیدگاه قرآن و روایات

Background: Self-control is self-management, by which anybody forces himself to do or not some acts. A person should control his desire to reach to this kind of management so it means suppression and restraining that has important impact on mental and spiritual health. The purpose of this research is expression of ways of achieving to self-control and its role in mental and spiritual health in view of Quran and narratives. Methods: This article is done in analytic-descriptive method with Quran-narrative approach. Results: This article states that self-control is one of effective component to reach mental relaxation. Continence makes: Balanced life, much patience, and strong relationship toward God and finally, makes life comfortably. This study concludes: Quran and narratives ways to achieve self- control are two: A) Cognitive: through Theology, Self-knowledge, Worldviews, B) Behavioral: through Fear and hope, Modesty and Chastity, Patience, fasting that increase components of power within and Reinforces behavioral components of external might. So both of them makes human achieve self-control. Discussion & Conclusion: This study concludes: Quran and narratives ways to achieve self- control are two: A- Cognitive: through Theology, Self-knowledge, Worldviews, B- Behavioral: through Fear and hope, Modesty and Chastity, Patience, fasting that increase components of power within and Reinforces behavioral components of external might. So both of them makes human achieve self-control.مقدمه: خودکنترلی مدیریت بر خویشتن است که انسان به واسطه آن، خود را ملزم به انجام یا ترک برخی امور می‌کند. رسیدن به این مدیریت، از طریق مهار امیال بوده و مفهوم ضمنی آن، فرونشانی یا مهارکردن است که تأثیر به سزایی در سلامت روحی و معنوی دارد. هدف از این مقاله بیان راه‌های رسیدن به خودکنترلی و نقش آن در سلامت معنوی از دیدگاه قرآن و روایات است. روش: نوشتار حاضر به روش توصیفی ـ تحلیلی، با رویکرد قرآنی ـ روایی انجام شده است. یافته‌ها: پس از بررسی منابع اصیل اسلامی بیان می‌دارد، خودکنترلی یکی از مؤلفه‌های مؤثر در رسیدن به آرامش روان است. خویشتن‌داری زندگی را متعادل، صبر را زیاد و رابطه با معبود را مستحکم کرده و در نهایت به زندگی رنگ آرامش و سلامتی می‌دهد. بحث و نتیجه‌گیری: قرآن و روایات برای رسیدن به خودکنترلی دو راهکار ترسیم نموده‌اند، الف ـ شناختی: از طریق خداشناسی، خودشناسی، جهان بینی و...؛ ب ـ رفتاری: به ‌واسطه‌ خوف و رجا، حیا و عفاف، صبر، روزه که باید این دو، توأمان ایجاد شود، مؤلفه‌های شناختی قدرت درون را افزایش می‌دهد و مؤلفه‌های رفتاری، توان برون را تقویت می‌نماید که این دو باعث حرکت انسان در جهت رسیدن به خودکنترلی می‌شوند

Multicomponent isotherm for biosorption of Zn(II), CO(II) and Cd(II) from ternary mixture onto pretreated dried Aspergillus niger biomass

In the present study, multicomponent competitive biosorption of heavy metal from aqueous solution onto pretreated dried Aspergillus niger in batch system was investigated. The adsorption data were fitted to the multicomponent Langmuir, Freundlich, Temkin and Sips equations. We used the genetic algorithm of biosorption in ternary mixture to evaluate the potential effects of each metal in the removal of other metals. In order to take both mechanisms of the cell-surface binding and intra-particle diffusion into account, an alternative model was investigated by combining the pseudo-second-order kinetics model and the intra-particle diffusion model. A model describing the process of biosorption by a single-stage batch design was developed and verified based on the Temkin isotherm model. Fundamentally, the outlook from these observations of the experiments that the pretreated dried biomass is a suitable absorbent for the removal of significant amounts of the heavy metal from the effluents of industrial wastewater is promising

Immunological mechanisms of the nucleocapsid protein in COVID-19

Abstract The emergence of corona virus disease 2019 (COVID-19), resulting from Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has left an indelible mark on a global scale, causing countless infections and fatalities. This investigation delves into the role of the SARS-CoV-2 nucleocapsid (N) protein within the HEK293 cells, shedding light on its influence over apoptosis, interferon signaling, and cytokines production. The N gene was amplified, inserted into the pAdTrack-CMV vector, and then transfected to the HEK293 cells. Changes in the expression of IRF3, IRF7, IFN-β, BAK, BAX, and BCL-2 genes were evaluated. The levels of proinflammatory cytokines of IL-6, IL-12, IL-1β, and TNF-α were also determined. The N protein exhibited an anti-apoptotic effect by modulating critical genes associated with apoptosis, including BAK, BAX, and BCL-2. This effect potentially prolonged the survival of infected cells. The N protein also played a role in immune evasion by suppressing the interferon pathway, evidenced by the downregulation of essential interferon regulatory factors of IRF3 and IRF7, and IFN-β expression. The N protein expression led to a substantial increase in the production of proinflammatory cytokines of IL-6, IL-12, IL-1β, and TNF-α. The N protein emerged as a versatile factor and was exerted over apoptosis, interferon signaling, and cytokine production. These findings carry potential implications for the development of targeted therapies to combat COVID-19 and mitigate its global health impact

Natural Products Derived Porous Carbons for CO2 Capture

Abstract As it is now established that global warming and climate change are a reality, international investments are pouring in and rightfully so for climate change mitigation. Carbon capture and separation (CCS) is therefore gaining paramount importance as it is considered one of the powerful solutions for global warming. Sorption on porous materials is a promising alternative to traditional carbon dioxide (CO2) capture technologies. Owing to their sustainable availability, economic viability, and important recyclability, natural products‐derived porous carbons have emerged as favorable and competitive materials for CO2 sorption. Furthermore, the fabrication of high‐quality value‐added functional porous carbon‐based materials using renewable precursors and waste materials is an environmentally friendly approach. This review provides crucial insights and analyses to enhance the understanding of the application of porous carbons in CO2 capture. Various methods for the synthesis of porous carbon, their structural characterization, and parameters that influence their sorption properties are discussed. The review also delves into the utilization of molecular dynamics (MD), Monte Carlo (MC), density functional theory (DFT), and machine learning techniques for simulating adsorption and validating experimental results. Lastly, the review provides future outlook and research directions for progressing the use of natural products‐derived porous carbons for CO2 capture
