The Decline Of Communism In Urdu Literature And Its Causes
Authors: Shabana A.Ballari  , Dr. Muhammad Yousuf  Nakewadi  
Published: March 2023

The term ‘ ‘Communism’’ refers to a social system in which the means of production (land, minerals, factories, banks, trade, etc.) are collectively owned by the community, and their production is distributed according to the creative labor of the mental or physical workers. The most famous concept of Communism was given by Karl Marx and Frederick Eagles. According to them, any socialist society has three basic characteristics; The means of production are jointly owned, all decisions are made democratically,and goods are made for utility rather than profit. The facts and history tell us that a large majority of the people in Russia under the leadership of Lenin overthrew the most oppressive tsarist capitalist government and established a labor democracy and put all the means of production under the democratic control of the workers. An all-out effort was made to meet public needs by maximizing production and utilization. As a result of which this revolution made Russia not only a developed country in a few decades from a most backward country, which was even more backward than today's Pakistan, but also the Soviet Union emerged as the second largest superpower in the world. It happened for the first time in human history, but the concept of such a high and fastest development in the capitalist society is also absent, thanks to which the real freedom of man in the society was provided with solid material foundations, even our enemies acknowledged it. In this article we will discuss the decline of Communism in Urdu Literature and will find its causes.

Published: March 2023

This study evaluates the current state of Dhaka's potable water and sanitation amenities. Moreover, the study addresses 6.1 and 6.2 of Sustainable Development Goal 6, which calls for optimal sanitation services and present conditions regarding water quality in Dhaka. In addition, the DWASA is the sole provider of potable water in the city, and as such, they are having a hard time keeping up with the demand for potable water. In addition, a significant number of private residences lack access to potable water and sanitary sanitation services on their properties. In order to complete this study, primary data were gathered through the use of questionnaire surveys, and informal interviews with experts; and secondary data were analyzed. The result is analyzed in three sections in which the first section shows the analysis regarding the privileged class, another one shows the underprivileged class analysis and the third one shows the combination of both. By breaking down the results, it is observed that the situation is way better than before in terms of consuming water from the improved sources, though the sanitation amenities need to be improved a lot though the progress is impressive. The study reveals that there is discrimination based on gender, economic capacity, and social standing for access to potable water and sanitary sanitation amenities. In addition, private-public partnerships can significantly enhance the current state of affairs. The report also recommends a number of activities to be taken in order to reach the goals attained in Dhaka.

Floods occur as a consequence of overflowing water over a large area of land that is which is beyond the soils ability to absorbed the water at the receiving rate. In this study, rainfall, slope, soil type, land cover, and drainage network were analyzed as causative factors of flooding. Furthermore, Landsat satellite images was used to assess land use and land cover (LULC). Flood vulnerable areas are were analyzed using the multicriteria evaluation process (MCE). A flood vulnerable areas map was generated after overlaying the maps of the major parameters responsible for flooding in GIS environment. The results show that the vulnerable areas are not confined in one area alone, however, the southmost part, the upper north and some part of the central accounting for about 25% are very vulnerable and high to flooding thanks to accumulations of multiple factors. Similarly, the result indicated that 53 %, 19% and 3% of the area were characterized as moderate, low and very vulnerable areas respectively. This research will help environmental managers and policy makers toward sustainable management of flooding affecting the area. This work will assist policy makers and environmental managers in identifying the major areas that are more at risk of flooding, thus, the little available resources can be allocated to these areas for better management practices and sustainable development.
Investor Reactions to Twin Transformers Announcements
Authors: Latinović Milica 
Published: March 2023

Research Question: This study aims to empirically test the effects of the digital and sustainability announcements of twin transformation companies on their shareholder value creation. Motivation: This paper builds on the vast research regarding the Efficient Market Hypothesis, such as the work of Fama (1970, 1998) which discussed efficiency of the capital markets. Stock markets reflect new information and future prices cannot be predicted based on historical prices. Investors’ reaction, e.g., overreaction or underreaction are well documented. Furthermore, Del Rio Castro et al. (2021) present contemporary research findings related to the emerging issue of reaching Sustainability Development Goals and connects it with digitalization. Ukko et al. (2019) find that a company will reach superior financial performance if managers simultaneously devote their efforts to sustainability and digitalization. This research builds on the previous literature and tries to determine whether stock market recognizes such efforts and whether there is efficiency. Idea: The idea behind this research is to empirically determine whether investors react to twin transformation. Short- and long-term investors’ reaction was tested against sustainability and digitalization announcements of the companies that are recognized by professionals to follow the path of simultaneous transformation. Data: The sample includes companies from the Accenture research of the European twin transformation companies. Data implemented in this study were collected from several sources. Share prices were collected from the Yahoo Finance website, and event announcements from corporate websites. Tools: The methodology employed in this research is the event study methodology. Cumulative abnormal returns are calculated for different event windows and t-statistic is calculated to determine whether there is statistically significant investors’ reaction to sustainability and digitalization events. Findings: Sustainability announcements yield significant market reaction. Depending on the news content they can be both positive and negative. Moreover, dates when the sustainability ranking of some company was released are among the most significant sustainability events. In most instances, investors do not react to the information instantaneously, they need time to absorb it. Investors do not find digitalization events to be significant. Contribution: To the best of the author’s knowledge, this is the first study to test investors’ reaction to digitally sustainable announcements of twin transformation companies.

Published: March 2023

Systematic studies have revealed interactions between components of the Hsp90 chaperone system and Fe/S protein biogenesis or iron regulation. In addition, two chloroplast‐localized DnaJ‐like proteins, DJA5 and DJA6, function as specific iron donors in plastidial Fe/S protein biogenesis. Here, we used Saccharomyces cerevisiae to study the impact of both the Hsp90 chaperone and the yeast DJA5‐DJA6 homologs, the essential cytosolic Ydj1, and the mitochondrial Mdj1, on cellular iron‐related processes. Despite severe phenotypes induced upon depletion of these crucial proteins, there was no critical in vivo impact on Fe/S protein biogenesis or iron regulation. Importantly, unlike the plant DJA5‐DJA6 iron chaperones, Ydj1 and Mdj1 did not bind iron in vivo, suggesting that these proteins use zinc for function under normal physiological conditions.

AbstractWhen synthesized under certain conditions, barium titanate (BaTiO3, BTO) nanoparticles are found to have the non‐thermodynamic cubic structure at room temperature. These particles also have a several‐fold enhanced dielectric constant, sometimes exceeding 6000, and are widely used in thin‐layer capacitors. A hydrothermal approach is used to synthesize BTO nanocrystals, which are characterized by a range of methods, including X‐ray Rietveld refinement and the Williamson–Hall approach, revealing the presence of significant inhomogeneous strain associated with the cubic phase. However, X‐ray pair distribution function measurements clearly show the local structure is lower symmetry than cubic. This apparent inconsistency is resolved by examining 3D Bragg coherent diffraction images of selected nanocrystals, which show the existence of ≈50 nm‐sized domains, which are interpreted as tetragonal twins, and yet cause the average crystalline structure to appear cubic. The ability of these twin boundaries to migrate under the influence of electric fields explains the dielectric anomaly for the nanocrystalline phase.

Published: March 2023

AbstractBiogenic amines (BAs) are important indicators for the evaluation of food spoilage and disease diagnosis. Thus, the detection of BAs with high practical potential is of great importance. In this work, a new BAs fluorescent probe design strategy is proposed by the intramolecular charge transfer (ICT) enhancement of the fluorescent probes, which is induced by the hydrogen bond interaction between probes and analyte. The probes T1 and T2 with donor–acceptor structure not only present a 140 nm bathochromic‐shifted emission, ultrafast responses (15 s for T1 and 25 s for T2), and high sensitivity (detection limit of 1.3 ppm for T1 and 2.6 ppm for T2) to cadaverine (the typical representative of BAs) but also discriminate a series of BAs and simply reused at least 30 times after air blowing. Further, a quantitative evaluation system is obtained based on T1 and T2 films. Through the Red/Green/Blue analysis with a smartphone, the total volatile basic nitrogen (an international standard to assess food spoilage) value can be output to quantitatively evaluate the freshness of food. The system is fast, visual, accurate, and non‐destructive, enabling consumers and all stakeholders in the food supply chain to monitor food freshness.

AbstractThe antiferromagnetic order in heterostructures of NiO/Pt thin films can be modified by optical pulses. After the irradiation with laser light, the optically induced creation of antiferromagnetic domains can be observed by imaging the created domain structure utilizing the X‐ray magnetic linear dichroism effect. The effect of different laser polarizations on the domain formation can be studied and used to identify a polarization‐independent creation of 180° domain walls and domains with 180° different Néel vector orientation. By varying the irradiation parameters, the switching mechanism can be determined to be thermally induced. This study demonstrates experimentally the possibility to optically create antiferromagnetic domains, an important step towards future functionalization of all optical switching mechanisms in antiferromagnets.
Toward Simultaneous Coherent Radiation in the Visible and Microwave Bands with Doped Molecular Crystals

Published: March 2023

AbstractCoherent sources exploiting the stimulated emission of non‐equilibrium quantum systems, i.e., gain media, have proven indispensable for advancing fundamental research and engineering. The operating electromagnetic bands of such coherent sources have been continuously enriched for increasing demands. Nevertheless, simultaneous generation of radiation in multiple widely‐separated bands presents formidable challenges with a single gain medium. Herein, a mechanism of simultaneously realizing the stimulated emission of radiation in the visible and microwave bands, i.e., lasing and masing actions, at ambient conditions by utilizing photoexcited singlet and triplet states of pentacene doped in p‐terphenyl is proposed. The possibility is validated by the observed amplified spontaneous emission (ASE) at 645 nm with a narrow linewidth around 1 nm from the pentacene‐doped p‐terphenyl crystal used for masing at 1.45 GHz and consolidated by a 20‐fold‐lower threshold of ASE compared to the reported masing threshold. The overall threshold of the pentacene‐based multiband coherent source can be optimized by appropriate alignment of the pump‐light polarization with the pentacene's transition dipole moment. This work not only shows a great promise on immediate realization of multiband coherent sources but also establishes an intriguing solid‐state platform for fundamental research of quantum optics in multiple frequency domains.

Published: March 2023

AbstractSn‐based perovskite materials are promising lead‐free alternatives in thin film photodetectors (PDs) for applications such as optical communications, night visions and biomedical near‐infrared imaging systems. However, constructing Sn‐based photodetectors with high sensitivity, ultrafast response, and good operation stability has been a challenge. Herein, the phenyl‐ethyl ammonium (PEA+) additive is introduced in pristine FASnI3, which regulates the thin film growth, passivates the trap/defect states, prevents Sn2+/Sn4+oxidation, and releases the crystal strain. The Resulting FA0.8PEA0.2SnI3 thin films exhibit highly crystalline order and flexibility. A self‐powered PD using FA0.8PEA0.2SnI3 as the active layer demonstrates excellent responsivity of 0.262 W−1, detectivity of 2.3 × 1011 Jones. And it possesses the fastest rise and decay time of 25 µs and 42 µs as compared with the state‐of‐art Sn‐based perovskite PDs. The transient absorption spectroscopy analysis validates greatly reduced trapping states and defects of FASnI3 with the PEA+ film for ultrafast response. A flexible Sn‐based perovskite PD without any encapsulation in air continuously shows ultrafast responses after 10,000 bending cycles. Meanwhile, a flexible imaging system can be realized by a 5 × 5 PD array with good sensing results. This study shows great potential in nontoxic and ultrafast Sn‐based perovskite PDs for flexible imaging applications.

Published: March 2023

AbstractThe tumor microenvironment (TME) is a complex and variable region characterized by hypoxia, low pH, high redox status, overexpression of enzymes, and high‐adenosine triphosphate concentrations. In recent years, with the continuous in‐depth study of nanomaterials, more and more TME‐specific response nanomaterials are used for tumor treatment. However, the complexity of the TME causes different types of responses with various strategies and mechanisms of action. Aiming to systematically demonstrate the recent advances in research on TME‐responsive nanomaterials, this work summarizes the characteristics of TME and outlines the strategies of different TME responses. Representative reaction types are illustrated and their merits and demerits are analyzed. Finally, forward‐looking views on TME‐response strategies for nanomaterials are presented. It is envisaged that such emerging strategies for the treatment of cancer are expected to exhibit dramatic trans‐clinical capabilities, demonstrating the extensive potential for the diagnosis and therapy of cancer.

AbstractNowadays the multifunctional approaches to kill oral bacteria based on various nanocomposites have made great progress against periodontal infections, while the material structure and its functional integration are still insufficient. Herein, this work proposes a therapeutic strategy of chemodynamical therapy (CDT) and photothermal therapy (PTT) in monocrystals to effectively enhance the synergistic treatment. The CuS/MnS@MnO2 consisting of hexagonal CuS/MnS nano‐twin‐crystal with a shell layer of MnO2 is developed. In this nanosystem, the purpose of synergistic treatment of periodontitis by combining PTT/CDT is achieved within a CuS/MnS monocrystal, where CuS serves to achieve photothermal conversion, dissipate the biofilm and transfer the heat in situ to the integrated MnS, thus promoting the Mn2+‐mediated CDT process. Meanwhile, the CDT process can generate the highly toxic hydroxyl radical to destroy extracellular DNA by utilization of endogenous H2O2 produced by Streptococci in the oral biofilm, cooperating with PTT to dissipate the bacterial biofilm. With the design of the outer shell of MnO2, the selective bacteria‐killing can be realized by producing oxygen which can protect the periodontal non‐pathogenic aerobic bacteria and threaten the survival of anaerobic pathogens. Therefore, such design via multipattern strategies to combat microorganisms would provide a bright prospect for the clinical treatment of bacterial infections.
