Addressing a specific aspect of visual communication, the focus of this paper is to examine the connection between elemental nature-inspired archetypal symbols and contemporary Visual Identity Marks, for example the archetypal Solar Cross to the BP VIM, Helios, by establishing the existence of a contextual relevance and relationship. It furthermore analyses the fundamental influence of these archetypal symbols upon the viewer/user (internal and external audiences), no matter what level of sophistication the viewer’s/user’s society has achieved. To build an appreciation of the continuity and effectiveness of the use of elemental nature-inspired archetypal symbols within a contemporary context, areas of expertise not traditionally utilised within visual communication, such as sociology, archaeology, theology and folklore were engaged. While being defined as “a recurrent symbol or motif in literature, art or mythology” (Random House Dictionary, 2012), an archetypal symbol also possesses a metaphysical quality. This metaphysical quality enables the symbol to act as a galvanising and motivating force, which re-enforces individual and group identity, and ultimately transmit a sense of the sacred and the institutional within a mutable world. The archetypal (natural) symbol is the response of the psyche reflecting the ‘internal truth’. The VIM (cultural) symbol is a vehicle to maintain power for financial or political profits as well as sustain group coherency, and individual identity. Encoded within both a ‘natural’, and a ‘cultural’ symbol, is a deep spiritual quality tapping into a deeper symbolic language which evolved from humanity relating back to nature. Drawing upon notions of individual interpretation, the paper analyses the very idea of personal and/or subjective mental constructs related to visual identity marks.

Microbial synthesis of silver nanoparticles is more advantageous and is eco-friendly to combat the various vectors that cause diseases in humans. Hence, in the present study a Bacillus strain is isolated from marine habitat and is evaluated for its ability to synthesize silver nanoparticles (AgNPs) and its efficacy evaluated against the immature stages of selected mosquito species. The effective candidate was confirmed to be Bacillus marisflavi after 16S rRNA sequencing. The synthesis of AgNPs was confirmed by UV-Vis spectrophotometer. Atomic Force Microscopic (AFM) analysis showed spherical nanoparticles. Size analysis using Scanning Electron Microscope (SEM) showed particles of nano size averaging 78.77 nm. The diameter of the particles analyzed by Dynamic Light Scattering (DLS) showed 101.6 nm with a poly-dispersive index of 0.3. Finally the elemental nature of the nanoparticles was identified by Fourier-transform infrared spectroscopy (FTIR). LC50 and LC90 values for the ovicidal, larvicidal and pupicidal efficacy of the AgNPs against the egg, larvae and pupae of Aedes aegypti, Culex quinquefasciatus and Anopheles stephensi respectively were evaluated. The present study revealed that the nanoparticles have an excellent toxic effect against the disease transmitting vector mosquitoes. Hence, the rapid synthesis of AgNPs would be an appropriate eco-friendly tool for biocontrol of vector mosquitoes.

Objective: This study was designed to evaluate the effect of Ayurvedic pharmaceutical procedures Shodhana and Marana on the chemical composition of the raw material. Methods: Iron and four iron-containing minerals were subjected to Shodhana and Marana. For Shodhana, Loha (Iron), Suvarnamakshika (Copper pyrite) and Mandura (iron slag,) were repeatedly quenched sequentially in sesamin oil, buttermilk, cow’s urine, natural vinegar and herbal decoctions. Kasisa (green vitriol) was grinded in the juice of Eclipta Alba. For Marana, these materials were first grinded in prescribed liquids and then incinerated in closed earthenware caskets in measured pits. Powdered Gairika (red ochre) was roasted in Cow’s ghee for its Shodhana. Samples of Loha (iron)-L1, Samanya Shodhita Loha–L2, Vishesha Shodhita Loha–L3, Loha bahsma-L4, Mandura (iron slag)–M1, Shodhita Mandura–M2, Mandura bahsma–M3, Suvarnamakshika (copper pyrite)-S1, Shodhita Suvarnamakshika-S2, Suvarnamakshika bhasma-S3, Kasisa (green vitriol)-K1, Shodhita Kasisa-K2, Kasisa bahsma–K3, Gairika (red ochre)-G1 and Shodhita gairika-G2; were studied using XRF and XRD techniques. Results: XRD findings suggested that the Chemical nature, elemental composition and Crystaline lattice structure of each substance were altered after extensive processings. XRF studies confirmed the multi-elemental nature of the final products. Reduction in particle size and other morphological changes were observed in intermediate and finished products during each procedure. Conclusion: The study indicates that the composition of material is altered as a result of Ayurvedic pharmaceutical processing, ’Shodhana and Marana.

AbstractIn this article I aim to bring to the fore a problematic trait of Polish philosopher Stanisław Brzozowski’s (1878–1911) thinking, which is his insistence on the metaphysical importance of human domination of nature through work, technology, and maximization of production. The focal point of the article is Brzozowski’s interpretation of Georg Sorel, with an emphasis on Reflections on Violence and the concept of the social myth. I argue that Brzozowski considers the primary strength of the social myth to lie in its contribution to such domination, because its principal trait is to provide man with a sublime feeling of elevation above nature. Furthermore, this feeling becomes a motive force for struggle against nature. In conclusion, I suggest that the perspective of the sublime is a fruitful path for future critical encounters with Brzozowski’s work. The first part of the article stresses the importance of the sublime in Reflections on Violence. Sorel uses this concept throughout his main work to describe the affective nature of the violence of the social myth, which coordinates the inclinations of the masses towards emancipation. The second part discusses how Brzozowski understands the social myth, law, and nationhood from the perspective of human domination of elemental nature.

Green synthesis of nanomaterials is advancing due to its ease of synthesis, inexpensiveness, nontoxicity and renewability. In the present study, an eco-friendly biogenic method was developed for the green synthesis of nickel oxide nanoparticles (NiONPs) using phytochemically rich Berberis balochistanica stem (BBS) extract. The BBS extract was rich in phenolics, flavonoids and berberine. These phytochemicals successfully reduced and stabilised the NiNO3 (green) into NiONPs (greenish-gray). BBS-NiONPs were confirmed by using UV-visible spectroscopy (peak at 305 nm), X-ray diffraction (size of 31.44 nm), Fourier transform infrared spectroscopy (identified -OH group and Ni-O formation), energy dispersive spectroscopy (showed specified elemental nature) and scanning electron microscopy (showed rhombohedral agglomerated shape). BBS-NiONPs were exposed to multiple in vitro bioactivities to ascertain their beneficial biological applications. They exhibited strong antioxidant activities: total antioxidant capacity (64.77%) and 2, 2-diphenyl-1-picrylhydrazyl (71.48%); and cytotoxic potential: Brine shrimp cytotoxicity assay with IC50 (10.40 µg/mL). BBS-NiONPs restricted the bacterial and fungal pathogenic growths at 1000, 500 and 100 µg/mL. Additionally, BBS-NiONPs showed stimulatory efficacy by enhancing seed germination rate and seedling growth at 31.25 and 62.5 µg/mL. In aggregate, BBS extract has a potent antioxidant activity which makes the green biosynthesis of NiONPs easy, economical and safe. The biochemical potential of BBS-NiONPs can be useful in various biomedical and agricultural fields.

Ted Hughes (1930-1998) began his career as a poet with the publication of The Hawk in the Rain in 1957. He was labelled as “an animal poet”. The cause of disintegration in modern man is his cutting from the elemental nature of his own. Modern man appears to be Yeats’s ‘falcon’ (Yeats, line 2) that goes on decentring himself without cognition and getting absent-minded of the life-force, ‘the elemental power circuit of the universe’. Science and technology lead to reasoning, and reasoning leads to scepticism, and scepticism creeps into human brain (the egg-head) and causes man to question the validity of spirituality and morality. It is this which has been focussed in this article.

Abstract Unzipping of the basal plane offers a valuable pathway to uniquely control the material chemistry of 2D structures. Nonetheless, reliable unzipping has been reported only for graphene and phosphorene thus far. The single elemental nature of those materials allows a straightforward understanding of the chemical reaction and property modulation involved with such geometric transformations. Here we report spontaneous linear ordered unzipping of bi-elemental 2D MX2 transition metal chalcogenides as a general route to synthesize 1D nanoribbon structures. The strained metallic phase (1T′) of MX2 undergoes highly specific longitudinal unzipping owing to the self-linearized oxygenation at chalcogenides. Stable dispersions of 1T′ MoS2 nanoribbons with widths of 10–120 nm and lengths up to ~4 µm are produced in water. Edge abundant 1T′ MoS2 nanoribbons reveal the hidden potential of idealized electrocatalysis for hydrogen evolution reactions at a competitive level with the precious Pt catalyst.

Carbon sequestration describes long-term storage of carbon dioxide or other forms of carbon to either mitigate or defer global warming and avoid dangerous climate change. Present study deals with the absorption of the atmospheric carbon in the study area selected by selecting planting methods that return biomass to the soil and enhance the conditions in which the carbon within the plants will be reduced to its elemental nature and stored in a stable state through Green belts. It is calculated that, Carbon Absorption by Green Belt Carbon absorption rate is approximated 49.27 kg per mature plant per year as per international standards. As per CPCB (2000) Guidelines, the trees to be planted are 1250 plants per acre, 1250 trees will absorb 1250 X 49.27 = 61587.50 kg of carbon per year per Acer. Project Site (Pench I & II - 1.16  acre) has sequestered 18724 kg of carbon per Acre.

Time is an inherent, constitutive aspect of narrative, whether the narrative concerns fiction or fact. To speak of narrative is to invoke time and multiple temporalities. Aristotle’s emphasis on action as a primary component of narrative implicitly acknowledges time as fundamental, since any action requires time. Whether narrative is seen as a series of connected events or as primarily the creation of a storyworld, the functional and structural roles of time stand. As a result of this, time has been one of the most analyzed, researched, and theorized subjects in the field of narrative theory. Discussions concerning such narrative concepts as story, plot, character, or point of view can hardly avoid considering temporal dynamics. And the elemental nature of time in narrative remains constant whether narrative is conceived more narrowly as depending on the presence of a narrator or is defined as the conjunction of a story and its representation. To consider the ways in which narratives involve the interrelationships of different temporalities is also to be reminded of the disjunction between so-called “real” or clock time and time as it is experienced. In contrast to the uniform directionality of clock time, time as it is experienced is constantly intertwined with memory and anticipation: that is, any experienced present is also interwoven with multiple pasts and futures. Narrative time captures this experience. Since a narrative is always a representation, a particular and subjective presentation of a story, the chronological sequence of events in a narrative may be represented in an infinite variety of ways. A given story can be told from its beginning moving through to its conclusion, or it can start with the end and build the story by revisiting earlier events, or it may start in the middle and proceed toward its end and at various points tack backward to earlier points, or it can do any combination of these. A representation of a story can create two storylines in parallel, the narrative crosscutting between the concurrent storylines, just as individuals can participate in one spatial-temporal setting while also immersed in another, whether technologically (as on the telephone or Internet) or mentally. In this way narrative time is in many ways truer to human experience than what is conventionally thought of as real time, namely the uniform absolute time undermined by Einstein’s discovery of relativity. What seems indisputable is that humans are hardwired to create and communicate with narrative; they habitually generate and trade in narratives as a way of making meaning of experience and of building connections with fellow humans. As a result, humans also constantly manipulate time, making sense of past, present, and future experiences through narrative. Just as anticipation of the future relies on the sense one makes of the present, the act of remembering has more to do with making narrative meaning than with accessing some fixed or stable mental recording of an event. Time is something an audience actively creates rather than something it passively experiences, and this may be borne out most vividly in the continuous activity of making narratives.

ABSTRACTBackgroundThe cue-reactivity paradigm is a widely adopted neuroimaging probe assessing brain activity linked to attention, memory, emotion, and reward processing associated with the presentation of appetitive stimuli. Lacking, is the apperception of more precise brain regions, neurocircuits, and mental operations comprising cue-reactivity’s multi-elemental nature. To resolve such complexities, we employed emergent meta-analytic techniques to enhance insight into drug and natural cue-reactivity in the brain.MethodsOperating from this perspective, we first conducted multiple coordinate-based meta-analyses to define common and distinct brain regions showing convergent activation across studies involving drug-related and natural-reward cue-reactivity paradigms. In addition, we examined the activation profiles of each convergent brain region linked to cue-reactivity as seeds in task-dependent and task-independent functional connectivity analyses. Using methods to cluster regions of interest, we categorized cue-reactivity into cliques, or sub-networks, based on the functional similarities between regions. Cliques were further classified with psychological constructs.ResultsWe identified a total of 164 peer-reviewed articles: 108 drug-related, and 56 natural-reward. When considering cue-reactivity collectively, across both drug and natural studies, activity convergence was observed in the dorsal striatum, limbic, insula, parietal, occipital, and temporal regions. Common convergent neural activity between drug and natural cue-reactivity was observed in the caudate, amygdala, thalamus, cingulate, and temporal regions. Drug distinct convergence was observed in the putamen, cingulate, and temporal regions, while natural distinct convergence was observed in the caudate, parietal, occipital, and frontal regions. We seeded identified cue-reactivity regions in meta-analytic connectivity modeling and resting-state functional connectivity analyses. Consensus hierarchical clustering of both connectivity analyses identified six distinct cliques that were further functionally characterized using the BrainMap and Neurosynth databases.ConclusionsWe examined the multifaceted nature of cue-reactivity and decomposed this construct into six elements of visual, executive function, sensorimotor, salience, emotion, and self-referential processing. Further, we demonstrated that these elements are supported by perceptual, sensorimotor, tripartite, and affective networks, which are essential to understanding the neural mechanisms involved in the development and or maintenance of addictive disorders.
