Electrochemical Evaluation of Human Hair Derived Carbon Particles
No full textPollution has become a great challenge for modern world. Hence, recycling trend is growing worldwide. Human hair, a fancy part of human body, creates a bulk of litter on trimming, yet has wide spectrum of applications. A facile thermal approach has been implemented in this research to synthesize carbon particles (CP) from waste human hair. CP surface analyses was made through SEM, ATR-FTIR, TGA & Raman. Efficient adsorptive behavior of synthesized CP against Zn and Pb has been observed with 70% Pb (9.325 mg/10 mg CP) and 90% Zn (37 mg/10 mg CP) adsorption. The augmented adsorptive capacity of CP ultimately finds its application in heavy metal removal from waste water. Cyclic voltammetry (CV) justified outstanding adsorption behavior of CP by speedy electron transfer, better charge storage and swift ionic diffusion; with 53 mC current carrying capacity and 1.98 to 4.37 cm(2) effective surface area. CV data has shown electrochemical irreversibility and double layer capacitance. CP conductivity has been observed from 19.78 mu S to 38.4 mu S, with. values between -17.4 mV and -28.6 mV.

Experiencing and writing Indigeneity, rurality and gender: Australian reflections
No full textThis paper has two interrelated aims. The first is to contribute to knowledge about rurality, gender and Indigeneity. This is undertaken by the first author, Bebe Ramzan, an Indigenous woman living in the Anangu Pitjantjatjara Yankunytjatjara (APY) Lands. Bebe shows similarities across rural and remote areas in Australia and details her knowledge and experience of home, rurality, rural communities, land and gender. The second aim of the paper is to examine issues surrounding the involvement of academic white women in Indigenous research. Writing from the position of feminist white women Barbara Pini and Lia Bryant reflect on theories of whiteness as cultural practice and in this paper contest representations of rurality in rural studies as white.No Full Tex

No full textDynamics of the Media Image of the Head of the Chechen Republic Ramzan Kadyrov in the Context of Political Media Communication in Russia
No full textThe theoretical aspects of the media image of the Russian region and its components are considered, the role of the image of the head of the republic in the context of the dynamics of political communications is indicated. The object of study is the image of the head of the Chechen Republic Ramzan Kadyrov, the features of positioning within the framework of the paradigm shift of the idea of Chechnya and its leader are revealed. In order to confirm the hypothesis, the data of the conducted studies are presented: media monitoring, dissacrs analysis of texts about Ramzan Kadyrov (chronological framework — February–August 2022). The author notes that the most important characteristics of the media image of a modern leader, identified by theoretical and practical research, are the behavioral actions of the leader, his ideological position, commitment to the ideology of the Russian state. Along with the description of the identified strategies, the author describes the causes and forecast of the dynamics of the media image of the regional leader
Sentic Computing for Social Media Analysis, Representation, and Retrieval
No full textAs the web is rapidly evolving, web users are evolving with it. In the era of social colonisation, people are getting more and more enthusiastic about interacting, sharing and collaborating through social networks, online communities, blogs, wikis and other online collaborative media. In recent years, this collective intelligence has spread to many different areas in the web, with particular focus on fields related to our everyday life such as commerce, tourism, education, and health. These online social data, however, remain hardly accessible to computers, as they are specifically meant for human consumption. To overcome such obstacle, we need to explore more concept-level approaches that rely more on the implicit semantic texture of natural language, rather than its explicit syntactic structure. To this end, we further develop and apply sentic computing tools and techniques to the development of a novel unified framework for social media analysis, representation and retrieval. The proposed system extracts semantics from natural language text by applying graph mining and multidimensionality reduction techniques on an affective common sense knowledge base and makes use of them for inferring the cognitive and affective information associated with social media

molecular dynamics
No full textWe present ab initio molecular dynamics calculations based on density functional theory to study the hydrogen-deuterium exchange in bulk and nanoclusters of MgH2. Our calculations reveal the important role of catalysts to diffuse the hydrogen at low temperatures and increase the diffusion rate. We determine the diffusion constants, < D > of deuterium, and show the single hydrogen-deuterium exchange in bulk and nanocluster of MgH2. Our calculated value of diffusion constant of deuterium in bulk MgH2 is in excellent agreement with the experimental value. Furthermore, we show the edge site importance of catalysts in the fast diffusion of hydrogen.</p
High pressure phase determination and electronic properties of lithiumamidoborane
No full textIn this study we report on the high pressure phase of the promising hydrogen storage material lithiumamidoborane (LiNH 2 BH 3), on the basis of density functional theory calculations with generalized gradient approximation. We take the five possible candidate structures, Pbca, Pbcn, Pcca, Pnma, and Pnnm for the high pressure study of LiNH 2 BH 3. The corresponding structures are relaxed with respect to fractional atomic coordinates and cell parameters, with the use of fully self-consistent ab initio electronic structure calculations to get the equilibrium parameters and total energies. Then we compare the energies of these phases and find that Pbcn is the most favorable phase at ≈100 GPa. Then we calculate the structural parameters of this phase. Finally, we calculate the density of states, Bader charge analysis, and corresponding electron density of this phase.</p
