Abstract	Biocatalytic membrane can be widely described as a state-of-the-art membrane process in which biological entity (e.g., enzyme) and nanoparticles are used. Such a combination is used widely in laboratory scale studies and so it demonstrates the potentiality to be applied in wastewater treatment applications. In particular, encapsulated enzyme, for instance, laccase within nanoparticles can inevitably result in an increasing the performance of removal in dual-microfiltration approach; nonetheless, encapsulation technique is economical for industrial application and allows us to use large volumes of the laccase enzyme. In today’s world, the removal of the micro-pollutant in water has become a vital environmentally challenge. Modification of polymeric ultrafiltration via non-covalent (adsorption) technique can significantly enhance the enzyme stability and reusability during the micro-pollutant removal. Apart from enzyme immobilization, more efforts should be made in biocatalytic membrane structure design for a practical application to enhance the subject of residual activity and operating stability of laccase-nanoparticle in the acidic and cationic pH and distinctive temperatures and results showed that laccase could be well immobilized on nanomaterials. The X-ray spectroscopy and Coupled Plasma-optical emission spectroscopy (ICP-OES) analyses were also demonstrated the presences of dispersion of laccase-nanoparticles in support membrane and ions leaching respectively. In this mini review, we demonstrated the main method used for preparing biocatalyst membranes which are called enzymatic nanoparticle membranes. In specific, the Laccase enzyme will be immobilized onto nanoparticles (NPs) by encapsulation technique in order to prepare the novel enzyme nanoparticles, and it also adsorb physically (non-covalent bond) on the surface of polymeric matrix for removing harmful pollutants. In addition to that, this review indicated the recent progress on dual-functional ultrafiltration biocatalytic membrane in the industrial application.

Abstract	Background: Transcranial direct current stimulation (tDCS) is a frequently used brain stimulation method; however, studies on tactile perception using tDCS are inconsistent, which might be explained by the variations in endogenous and exogenous parameters that influence tDCS. Objectives: We aimed to investigate the effect of one of these endogenous parameters-the tDCS amplitude-on tactile perception. Methods: We conducted this experiment on 28 undergraduates/graduates aged 18-36 years. In separate sessions, participants received 20 min of 1 mA or 1.5 mA current tDCS in a counterbalanced order. Half of the participants received anodal tDCS of the left SI coupled with cathodal tDCS of the right SI, and this montage was reversed for the other half. Pre- and post-tDCS tactile discrimination performance was assessed using the Grating Orientation Task (GOT). In this task, plastic domes with gratings of different widths cut into their surfaces are placed on the fingertip, and participants have to rate the orientation of the gratings. Results: Linear modeling with amplitude, dome, and session as within factors and montage as between factors revealed the following: significant main effects of grating width, montage, and session and a marginally significant interaction effect of session and amplitude. Posthoc t-tests indicated that performance in GOT improved after 1 mA but not 1.5 mA tDCS independent of the montage pattern of the electrodes. Conclusion: Increasing the stimulation amplitude from 1 mA to 1.5 mA does not facilitate the tDCS effect on GOT performance. On the contrary, the effect seemed more robust for the lower-current amplitude.

Abstract	Möglichkeiten der Integration islamischer Elemente in die kognitive Verhaltenstherapie (KVT) werden erläutert. Da die KVT erheblich auf der Lernpsychologie aufbaut und im Koran und in den Hadithen die Themen "Lernen" sowie "lebenslange Bildung" mehrfach betont werden, können theologisch geschulte Psychotherapeutinnen und Psychotherapeuten muslimischen Patientinnen und Patienten die KVT relativ leicht nahebringen. Dennoch birgt die mögliche Integration von islamischen Aspekten in die KVT mehrere Herausforderungen. Daher wird zunächst kritisch diskutiert, unter welchen Bedingungen diese Integration sinnvoll sein kann und wann sie eher kontraindiziert wäre. Anschließend wird anhand von zwei Fallbeispielen aufgezeigt, wie islamische Aspekte mit Methoden der KVT sowie modernen Erkenntnissen der Gehirnforschung zielführend integriert werden können.

Abstract	La evidencia empírica tradicional ha señalado que las personas de más edad tienen actitudes más refractarias a participar en el ámbito político y social. Sin embargo, es un área de investigación todavía inconclusa, debido a la imposibilidad metodológica que provoca no poder atender simultáneamente los efectos conjuntos de la edad, la generación política de pertenencia y el periodo considerado. Este trabajo sortea esta problemática tratando la edad no como variable continua, sino agrupada y utilizando cincomuestras cuasilongitudinales provenientes de la Encuesta Mundial y de la Encuesta Europea de Valores y del Banco de Datos del CIS, abarcando un periodo de casi treinta años. Los resultados revelan que, cuando se controlan simultáneamente así estos efectos, el ciclo vital no resulta un factor explicativo de las actitudes hacia la participación ciudadana.

Abstract	Chatbot is a software agent that is used to conduct intelligent conversations between machines and humans. Chatbots are mostly depend on Natural Language Processing (NLP). In this paper, the design and implementation of a chatbot are provided to help Kurdish speakers in using online conversations via texts to find answers instead of direct contact with human agents. The NLP-based software agent is implemented using the Chatfuel platform. Chatfuel uses artificial intelligence to communicate with humans by simulating human conversations through voice commands or texts. The proposed chatbot is tested on an electronic tourist guide that helps visitors to the religious places in the mountainous village of Barzanja that is located in Iraqi Kurdistan. The case study is conducted by using three-hundred questions and answers. One hundred volunteers participated in this study. The participant asks a question and the bot provides an answer if it recognizes the question, otherwise it provides a default answer along with a suggestion of how to use the system properly. The data of these experiment is collected, analyzed, and problems regarding Kurdish language are detected. Designing software agents for processing Kurdish texts faces many challenges. Kurdish texts have not yet been processed using natural language processing (NLP). In addition, Kurdish font disorder and the lack of standardized keyboards and writing styles makes processing Kurdish text difficult. Furthermore, Kurdish language consists of variety of different dialects with different typing styles. In this research, we specifically focus on the design of a software agent for the Central Kurdish (Sorani) dialect. We managed to solve some of the problems related to the Kurdish language and suggest solutions to others.

Abstract	Background: Thyrotoxic hypokalemic periodic paralysis (THPP) is a rare complication of hyperthyroidism characterized by thyrotoxicosis, hypokalemia, and paralysis. It is the most common form of acquired periodic paralysis. THPP is precipitated by strenuous exercise, a high carbohydrate diet, stress, infection, alcohol, albuterol, and corticosteroid therapy. It is most common in Asian men with hyperthyroidism and exceptionally rare in black people. Case presentation: A 29-year-old man was admitted to the emergency department in Somalia with a sudden onset of paralysis after a high carbohydrate meal. Laboratory investigations showed low serum potassium 1.8 mEq/l (3.5-4.5), and biochemical thyrotoxicosis with TSH 0.006 miu/l (0.35-5.1), total T3 3.2 ng/ml (0.9-2.8) and total T4 13.5 ng/ml (0.6-1.2). He was successfully treated with potassium chloride infusion and an antithyroid drug, methimazole. Conclusion: To prevent life-threatening cardiac and respiratory complications, it is critical to consider and diagnose THPP early, even in populations where the condition is rare.

Abstract	The global community is facing an existential crisis that threatens the web of life on this planet. Climate change, in addition to being a fundamental justice and ethical issue, constitutes a human rights challenge. It is a human rights challenge because it undermines the ability to promote human flourishing and welfare through the implementation of human rights, particularly the right to life and the right to health. It is also a human rights challenge because climate change disproportionately impacts poor and the vulnerable people in both low-income and high-income countries. Those living in many low-income countries are subject to the worst impacts of climate change even though they have contributed negligibly to the problem. Further, low-income countries have the fewest resources and capabilities at present to adapt or cope with the severe, long-lasting impacts of climate change. Building on human rights principles of accountability and redress for human rights violations, this paper responds to this injustice by seeking to make long-neglected societal amends through the implementation of the concept of climate reparations. After discussing the scientific evidence for climate change, its environmental and socioeconomic impacts, and the ethical and human rights justifications for climate reparations, the paper proposes the creation of a new global institutional mechanism, the Global Climate Reparations Fund, which would be linked with the United Nations Human Rights Council, to fund and take action on climate reparations. This paper also identifies which parties are most responsible for the current global climate crisis, both historically and currently, and should therefore fund the largest proportion of climate-related reparations.

Abstract	Removal of selenite (Se (IV)) from wastewater is vital due to its more toxic and mobile properties. In this study, a novel dendritic silver‐dendrites@ copper with hierarchical side‐branches were synthesized through a two‐pot rapid, facile, and green precipitation route. Characterization of the dendrites by transmission electron microscope (TEM), scanning electron microscope (SEM), dynamic light scattering (DLS), and X‐ray diffraction spectroscopy (XRD) confirmed the proper preparation of dendritic AgCu nanostructure. Significantly, the Ag@Cu nanostructure has high specific surface area (150 m²/g) and excellent adsorption activity toward selenite. The adsorption rate of Se (IV) on the dendritic AgCu reaches 94% within 60 min under normal adsorption procedures. Both adsorption kinetics and isotherms have been described well by the pesudo‐second order model and Langmuir model, respectively. The noticeable high adsorption capabilities can mainly accredit to the effect of the hierarchical side‐branched structure. Therefore, the dendritic AgCu nanostructure has a room of treating heavy metals‐contaminated industrial wastewater streams. PRACTITIONER POINTS: Silver‐dendrites@ copper with hierarchical side‐branches were synthesized through a rapid and green precipitation route using copper nanoparticles. The prepared nanostructure was applied for Se (IV) adsorption at varying operational conditions (contact time, pH, and dose). High adsorption capacity for Se (IV) up to 173.1 mg/g was achieved using the prepared nanoparticles applying Langmuir isotherm model.
