GCC nations are transforming their energy industry and market around the world which is promising their economic efficiency and technology development. Nevertheless, this open energy market across the world has raised a question about energy security and power demand. This energy market globalization has pushed the GCC Nations to pay attention to the control of supply and demand of power. Interconnection of power network between the GCC Region is optimistic pace to secure the future anticipated power fallouts. And also installation of Renewable Energy projects will support GCC to accommodate their increasing power demand. This paper discusses about how the energy market globalization has affected the power supply and demand of GCC nations, their concerns and recent progress towards its resolution

© 2023, The Author(s).The importance of water for all living organisms is unquestionable and protecting its sources is crucial. In order to reduce water contaminants, like toxic metals and organic dyes, researchers are exploring different techniques, such as adsorption, photocatalytic degradation, and electrolysis. Novel materials are also being sought. In particular, biopolymers like guar gum and xanthan gum, that are eco-friendly, non-toxic, reusable, abundant and cost-effective, have enormous potential. Gum-based nanocomposites can be prepared and used for removing heavy metals and colored dyes by adsorption and degradation, respectively. This review explains the significance of gum-based nanomaterials in waste water treatment, including preparative steps, characterization techniques, kinetics models, and the degradation and adsorption mechanisms involved.publishersversionpublishe
Design of a framework for the aggregator using demand reduction bid (DRB)
No full textDemand side management (DSM) in smart grid paradigm is an energy management strategy of the grid using advanced data communication and networking. The aggregator, a third party entity, is appearing as a key player in managing the demand during the peak hours between the utility and the consumer. In this work, a general framework is discussed and focuses on the interactional issues between the utility, the aggregator and the consumers. The paper also discusses the role of communication in the context of interaction among the three players. In addition, it also presents the model of the framework which can enable the consumer to effectively participate in the DSM. The proposed model considers the direct load control (DLC) program which uses the concept of demand reduction bid (DRB) in aggregated demand response
Biogenic adsorbents for removal of drugs and dyes: A comprehensive review on properties, modification and applications
No full textPublisher Copyright:
© 2023 The AuthorsThis comprehensive review explores the potential and versatility of biogenic materials as sustainable and environmentally benign alternatives to conventional adsorbents for the removal of drugs and dyes. Biogenic adsorbents derived from plants, animals, microorganisms, algae and biopolymers have bioactive compounds that interact with functional groups of pollutants, resulting in their binding with the sorbent. These materials can be modified mechanically, thermally and chemically to enhance their adsorption properties. Biogenic hybrid composites, which integrate the characteristics of more than one material, have also been fabricated. Additionally, microorganisms and algae are analyzed for their ability to uptake pollutants. Various influential factors that contribute to the adsorption process are also discussed. The challenge, limitations and future prospects for research are reviewed and bridging gap between large scale application and laboratory scale. This comprehensive review, involves a combination of various biogenic adsorbents, going beyond the existing literature where typically only specific adsorbents are reported. The review also covers the isotherms, kinetics, and desorption studies of biogenic adsorbents, providing an improved framework for their effective use in removing pharmaceuticals and dyes from wastewater.publishersversionpublishe

Multiple Impacts of Illegal Logging: A key to Deforestation Over the Globe
No full textThis article describes the main impacts of the illegal logging activities with emphasis on the most important deforestation affected regions; Indonesia, Bangladesh, Australia, India, Peninsular Malaysia, and Pakistan. Although the discussion is concentrated on the socioeconomic, environmental and governance impacts, it must be stressed that the term deforestation is the roadmap where the environmental values, the economy, and welfare of forest-dependent communities are crushed without any kindness. Despite multiple efforts, the results in the combat of illegal logging are far from satisfactory. Furthermore, governments and businesses must implement the triple bottom line concept in order to achieve sustainability

© 2024 The AuthorsThis review explores the integration of graphitic carbon nitride (g-C3N4) with model drugs and diverse formulations to obtain nanocomposites with potential for cancer therapy. Beyond the synthesis, the study also deals with cancer-affected organs, elucidates mechanisms of drug action and categorizes g-C3N4-based anti-cancer compositions. The responsive elements contributing to cancer inhibition under the chemotherapeutic influence include reactive oxygen species (ROS), mitochondrial potential, oxidative stress, magnetic responsiveness, profound thermal and photo energy penetration, metal retention toxicity, adenosine triphosphate (ATP) blockade in cancer cells, insulating microenvironments within tumours and immune-modulating antibodies. Notably, breast, prostate, lung, ovary and stomach cancers owe their genesis exclusively to abnormal cell proliferation. Our review reveals that the integration of model drugs (MD) with metal ions (MI) on g-C3N4 (g-C3N4/MDMI) shows enhanced biological activity, compared to metal ions and model drugs alone. The paper refers to several characterization techniques to decipher intricate data patterns and facilitate explanations of in vitro analyses focused on cancer cell viability and proliferation. Upon analysis of all data, g-C3N4 emerges as a compelling drug carrier, particularly within the anticancer drug delivery systems. This review not only emphasizes the immense potential of g-C3N4 nanocomposites but also paves the way for future advancements in effective cancer treatments.publishersversionpublishe
A Cluster Analysis of the Reportage “Chinese Women Protest at Gynaecology Checks for Civil Service Jobs” in the Guardian
No full textDrawing upon Kenneth Burke’s cluster analysis, this article explores how the guardian journalist Jonathan Kaiman in his news article “Chinese women protest at gynecology checks for civil service jobs” constructs his rhetoric in convincing the audience of the ideology of gender discrimination in the practice of gynecological examination to women civil service applicants in China. The analysis reveals that civil service “examination” in China has been transformed into gynecological “examination”, which is clearly a discrimination against women applicants. In the end, the author argues that the ideology of gender inequality perpetuated by official levels in China is the primary reason why women civil service applicants have to undergo gynecological examinations. Only by eliminating the ideology of gender inequality that exists in official levels can it really enable women to compete with men equally in job application. Keywords: Cluster analysis, Gender discrimination, Gynecological examination, Civil service examination
A case study of the novel Siddhartha from the perspective of intertextuality
No full textThis article argues for intertextuality as a critical and analytic method for reading literary texts. To develop this argument first a critique on structuralism and deconstruction has been presented. Secondly, it has been pointed out that both these theories are not adequate because both of them take their departure from a linguistic theory of Ferdinand de Saussure which is not sufficient to understand the nature of text, author and the society in which they take place. It has been argued on the contrary that the idea of dialogicality proposed by Mikhail Bakhtin does seem helping us better to resolve the issues which cannot be tackled by both structuralism and deconstruction. The idea of dialogicality gives birth to intertextuality which, as a suggestion, should be adopted for literary and critical practices. In the end part of this article a case study of the novel Siddhartha by Hermann Hesse, a German writer, has been presented to make the idea of intertextuality clear and forceful.
