Morpho-Physiological and Enzymatic Responses of Zinnia (Zinnia elegans L.) to Different Metal Hoarded Wastewaters
No full textWastewater, as an irrigation source, offers various advantages, significantly enhancing soil fertility, crop development, soil health, and preventing soil alkalinization. The introduction of non-conventional water resources (treated greywater, and treated wastewater) in floriculture plays a crucial role in water conservation. This study examined the impact of treated greywater (wastewater generated from domestic activities such as bathing, showering, laundry, and dishwashing) and treated wastewater (water from toilets, showers, kitchen sinks, and industrial processes) on photosynthetic characteristics, stress-related metabolites, and antioxidative enzymes in zinnia plants. A six-month pot experiment was conducted, with three water sources (canal water, treated greywater, and treated wastewater) and two zinnia varieties (Peter pan and Dreamland). During the flowering stages, when the zinnia flower petals were fully opened. Several parameters were measured, including pigments, photosynthetic attributes, total soluble protein, hydrogen peroxide and glycinebetaine. Moreover, antioxidant enzymatic activities like peroxidase (POX), catalase (CAT), superoxide dismutase (SOD), and ascorbate peroxidase (APX) were also investigated in zinnia plants to assess their resilience against abiotic stressors caused by high levels of heavy metals and excessive nutrients present in wastewaters. Results indicated that treated greywater (TGW) significantly improved vegetative parameters, such as plant height, leaf number, leaf area, and stem diameter. Additionally, flowering attributes, including the number and diameter of flowers, as well as fresh and dry plant biomass, increased in Peter pan variety under treated greywater irrigation. Chlorophyll and carotenoid contents were notably reduced in plants irrigated with treated greywater and treated wastewater. Photosynthetic attributes, such as stomatal conductance, transpiration rate, and photosynthetic rate, significantly improved in zinnia plants under treated greywater irrigation. Stress-related metabolites and antioxidant enzymatic activities also showed substantial enhancements under treated greywater irrigation. Principal Component Analysis (PCA) confirmed the positive effect of treated greywater on flower quality, plant biomass, and physiological processes. Utilizing treated greywater and wastewater for Zinnia cultivation is a promising approach. Ensuring the ongoing monitoring and management of harmful substances in wastewater is vital, involving regular testing, quality control, and other actions. This practice contributes to environmental conservation, sustainable agriculture, efficient water resource management, reduced energy use, and enhanced soil health, making it a cost-effective and eco-friendly option for floriculture
Alleviation of cadmium stress and improved growth performance of periwinkle (Catharanthus roseus L.) by foliar application of zinc oxide nanoparticles
No full textCadmium (Cd) is a nonessential and very toxic element that confines the growth of ornamental plants worldwide. Nanoparticles (NPs) have been used as a novel approach to act as nano-fertilizers and directly alleviate the Cd stress. However, its defensive mechanisms are not well understood in ornamental/medicinal plants, especially Catharanthus roseus (periwinkle). The objectives of the current experiment are intended to examine the impacts of zinc oxide nanoparticles (ZnO[sbnd]NPs; 25 mg l-1) on the reduction of oxidative stress by enhancing antioxidant activities, physiological improvements, and elemental status in periwinkle plant parts under Cd stress (0.5 mM). The periwinkle plants were transplanted and exposed to Cd stress one week later by soil drenching, whereas, ZnO[sbnd]NPs were applied after 14 days by foliar supplementation. The Cd toxicity significantly reduced the morphological traits, negatively affected the pigments and photosynthetic apparatus, abridged antioxidant enzyme activities, and Cd accrual in periwinkle plants. However, exogenous ZnO[sbnd]NPs supplementation produced elevated plant height, flower numbers, root length, plant fresh and dry biomass, chlorophyll, and carotenoid contents in Cd-stressed plants. Likewise, the ZnO[sbnd]NPs have also regulated the gaseous exchange rates, antioxidant enzymes (SOD, CAT, APX), soluble protein, and free proline contents in Cd-polluted periwinkles. The application of ZnO[sbnd]NPs also considerably reduced the hydrogen peroxide (−25 %) and malondialdehyde (−47 %), activated by Cd stress. Furthermore, the Zn and Cd contents were also elevated and reduced, respectively, in ZnO[sbnd]NPs supplied Cd-stressed plants. The present experiment recommends that the exogenous supplementations of ZnO[sbnd]NPs are a feasible and sustainable strategy for enhancing the growth attributes and reducing the Cd levels in periwinkle plants in metal-hoarded soil conditions
Psychological analysis of Younis Al-Khattat, the novel Honaa Al-Warda According to Freud's theory
No full textSigmund Freud provided the basis for analyzing literary works using psychoanalytic methods. The novel Honaa Al-warda, by the Jordanian writer Amjad Nasser, is one of the political novels in which the author paid special attention to psychological issues and the hidden struggle of the inner forces of the novel’s hero, Younis Al-Khattat, in dealing with its subject. Therefore, the current research attempts to study the internal conflict of Yunus Al-Khattat, the hero of this novel, based on Freud’s theory, and to analyze the outcome of the battle between the id, the ego, and the superego over his individual and social life. The results of the research indicate that heredity, family environment, relationships with peers, the tense political and social atmosphere, and the propaganda of intellectual and political organizations play a major role in shaping Yunus’s acute internal conflict. His comprehensive internal anxiety is caused by the establishment’s pressures on himself and his logical ability and its insistence on quickly meeting its irrational, material and emotional demands, as well as the destructive and false ideals of the superego that lead him to many adventures and ambitions, and work that leads to the assassination of the president and exposes his life, his fate, and the fate of his family to danger.Keywords: psychoanalysis, Freud's theory, Amjad Nasser, Honaa Al-Warda's novel, Younis Al-Khattat. Extended Summary IntroductionPsychoanalysis is a literary criticism method that studies psychological novels and, through exploring the characters in the novel, explains how their personality is constructed. Systematic and scientific criticism of psychology began concurrently with the beginning of psychology and the publication of Sigmund Freud's works at the end of the nineteenth century. Since Freud was the first to subject literature to psychological interpretation, he had a great interest in reading literary works, as literature had a profound impact on his personal and scientific life, and he used it to expand the horizons of his work in psychoanalysis as well as to expand the scope of his psychological discourse. His views on the personal characteristics of writers and artists are not merely psychoanalytic, but rather a combination of psychological theories and his literary taste. Amjad Nasser is a well-known Jordanian creative writer who has paid special attention to psychological issues in writing his novels. Honaa Al-Warda is Nasser's second novel nominated for the International Booker Prize in 2018. It narrates the life events of a leftist activist named "Younis Al-Khattat" and expresses all the traits of his personality in the form of behaviors, actions, and political adventures. Honaa Al-Warda is a political novel that shows the developments in the Arab world in the seventies. Therefore, the psychological analysis of the main character in this novel can express the influence of individuals in society in Arab countries from political, social, cultural, and intellectual circumstances and represents many historical unknowns. Therefore, the current study, based on Freud's theory on the three levels of personality, attempts to study the role of the internal conflict of Younis, the hero of the novel, in shaping his personality type. First, Freud's theory and the tripartite structure of personality are analyzed from his point of view, then Younis's internal developments are analyzed according to Freud's theories and the impact of his internal conflict on his personal and social life is expressed. This research aims to answer these questions:1- What are Nasser's goals in creating the character of Younis?2- How does the battle between the id and the ego occur in the character of Younis and what is the result of the subconscious's dominance over his consciousness?3- How does the Oedipus complex affect the creation of the superego of Younis and what is the result of the conflict of the ego with the superego?4- How does the conflict of the three forces in the character of Younis affect his personal and social life?MethodologyFreud is considered the first psychologist to assign a specific structure to the human personality in which the internal actions of the human being are formed under the influence of instincts and conflicting forces. From the beginning of his life until its end, the human being constantly fights and quarrels with various forces and people, but this battle is not limited to the outside world. "Freud searches for this conflict in the depths of human existence, which causes the formation of the human personality and intellectual development"; the human world is an arena of confrontation between different forces that interact automatically with each other, which leads to the health of the human soul and spirit, and the absence of this interaction causes anxiety and insecurity in the human personality. Freud sees that the structure of the human personality includes three parts: the id, the ego, and the superego. "These three parts of the personality interact at three levels of psychological life with each other, and the ego passes through different spatial levels and has conscious, semi-conscious, and unconscious elements. While the superego is semi-conscious and unconscious, the id is completely unconscious"; these levels are completely intertwined and cannot be separated, and the ego exists at all these levels under different conditions.DiscussionBy describing the whispers of Younis Al-Khattat and his tense inner life from childhood to youth, Amjad Nasser depicts the role of the authoritarian atmosphere, suffocation, lack of freedom and social justice, and the violation of the principle of democracy that govern some Arab countries in shaping the internal conflict of individuals in Arab societies and the desire for violent actions. He also criticizes the exploitation of authoritarian individuals like Younis by political organizations that push them, by stimulating their internal forces, to violence and terrorism in order to achieve their goals. In reality, the dreams of such a generation of young people turn into a pile of ashes. The id's insistence on satisfying his material, immoral and irrational needs leads to the formation of his aggressive, hasty and reckless personality that exhausts his rationality and ego with repeated demands. The id of Yunus, by its rebellion against the ego, passes from the unconscious and semi-conscious area and enters the conscious level, and the ego weakens and is unable to provide Yunus with the appropriate ideas and solutions to overcome problems, and great anxiety and confusion dominate his existence.ConclusionThe superego of Younis, due to the failure to resolve the Oedipus complex in his childhood and his failure to undergo the process of understanding his parents’ behavior and not following their orders and what should and should not be done, takes on an abnormal, unnatural, and neurotic state. Younis thinks that his father is his competitor in winning his mother’s love, and he constantly tries to rescue himself from his father’s control. The desire for superiority and authority becomes entrenched in him, and the false ideal ego is formed in him, far from external reality, leading to walking in a world of fantasy and dreams, and causing the superego and its unreasonable ideals to turn against the ego and blame it for following the principle of reality. It is stubborn like the id and insists on achieving its demands in an irrational way, which makes Younis justify terrorism and violence and consider it a value and a custom, regardless of his responsibilities towards his wife and family.

Advanced AC-AC, AC-DC and DC-DC power electronics converters for smart grid
No full textConverters and controllers of power electronics are the lifeblood of many emerging technologies in manufacturing, information technology and more. This thesis investigates the design, analysis, and implementation of advanced AC-AC, AC-DC and DC-DC power electronics converters for high voltage gain and voltage sag/swell compensation in power grids. Firstly, direct single-phase AC-AC converter by using an auto transformer approach and impedance network is presented. It has buck-boost operation in a single-stage direct AC-AC conversion. The high voltage gain is enabled through magnetic coupling and turn ratios of coupled transformer. Notably, it employs a coupled transformer, achieving high voltage gain while maintaining an optimal switching duty ratio, with a 1:1 unity turn ratio. Secondly, AC-DC converter with three output terminals for use in the DC applications is explained. This converter converts an input AC voltage into two output DC voltages. The output DC voltages can be obtained higher or lower than the input AC voltage. The proposed converter with four active switches is analyzed in detail, and control strategies are developed. Finally, a switched-inductor A-source DC-DC converter with an impedance network is presented. The operations of topology are based on the autotransformer technique, which are effective for a wide range of applications due to better DC voltage gain. This network achieves higher voltage gain with less switching duty cycle by using a minimal turns ratio rather than other magnetically coupled impedance source networks. The previous converters usually have high total harmonic distortion (THD) due to discontinuous input current and are not able to operate in buck-boost mode simultaneously. Integrated circuits are becoming smaller, but existing power electronics converters are still inefficient, large, and expensive. Thus, proposed converters have simple structures, operations and share a common ground between the input and output, which enhances the reliability of the power conversion systems. Experimental results are obtained to validate the operations and effectiveness of the proposed converters for the power grids.Includes bibliographical reference

No full textA critical Hadith study of the Tablighi Nisab and its intellectual impact on the Jama at Al-Tabligh.
No full textIt is common knowledge that movements are based on ideologies that are considered to be the foundation of their methodologies and policies. Often, these ideologies are disseminated in letters, books or other publications that present them in the form of texts that are available to the public and become sources of information about these movements. The Jamā‘at Al-Tablīgh is one of the movements that plays an important role in the sphere of Islamic Da‘wah (mission). This movement adopts some techniques of Da‘wah; one of the most important among them being Targhīb, which expounds the merits and benefits of virtuous deeds. This research studies one of the most popular books of the movement, titled in Urdu Tablīghī Nisāb, which uses this sort of technique. It was written by the famous H adīth scholar and the general supervisor of the movement, Shaykh Muhammad Zakariyyā Kāndahlawī. The first publication of the book in Urdu was in (1374 H./1955 CE.). It has been translated into several different languages, and this reflects the importance of the book. The thesis falls into six chapters, including the introduction as chapter one and the conclusion as chapter six. Chapter two talks about the definition of weak Ahadīth and its different types, criteria used to determine weak Ahādīth, different trends among the scholars regarding weak Ahādīth, the consequences of using and publicizing weak and fabricated Ahādīth. Chapter three deals with the biography of the author of the Tablīghī Nisāb, while chapter four focuses on the book itself, by specifying the original name of it and looking at the different editions and translations, and compares the original Urdu with the Arabic and English versions. The chapter also discusses the methodology of the author in his book. Chapter five is a critical study of the Ahādīth of the Tablīghī Nisāb, whether found in the main text of the book or in the commentary to verify the Ahādīth in terms of their authenticity or weakness
