Phyto-Nanofabrication

Green synthesis of metallic nanoparticles through natural entities (i.e., bacteria, actinomycetes, yeast, fungus, microalgae, seaweed, plants, and plant-derived materials) has become an advantageous and ecofriendly approach. However, phytocompounds of plant extract have achieved huge attention since by utilizing them high yield NPs with desirable size and shape, which can be produced through single-step synthesis scheme. Plants retain diverse biochemicals that exhibit strong hyper-accumulating potential, crucial for metallic ion reduction to metallic NPs, like platinum, gold, silver, titanium oxide, iron oxide, copper oxide, zinc oxide, palladium, etc. Here, previously published studies were reviewed for providing the latest scientific evidence on biosynthesis of metal and metal oxide NPs using different plant materials, especially medicinal plants and food and agro-wastes.

Horizontality, Negotiation, and Emergence: Toward a Philosophy of Environmental History

In this article, I intend to creatively synthesize both the empirical findings and the theoretical formulations put forward by self-proclaimed environmental historians, as well as those by the scholars who preceded and influenced them. Establishing a dialogue with the broader field of Environmental Humanities, especially posthumanism, I propose three principles for writing environmental histories: horizontality, negotiation, and emergency. Horizontality refers to the inexistence of a given and absolute 'ground' for human life. We walk, build our houses, earn a living, and develop ideas and cultures, not on top of an ontological floor, but attending to and being attended by the bodies surrounding us, some of them animated and some not, some solid and some liquid and gaseous. To inhabit is to make oneself available to be inhabited. Mutual habitation weaves assemblages that are both the continent and the content of life. Negotiation alludes to the human conversation with a larger world, both animated and inanimate, about coexistence. Humans never get everything they want, just the way they want it, from their relationships with nonhumans. Though people rarely recognize this, the only way history can be made is through compromise with the rest of the biosphere. This means that humans are continuously becoming, as they and their activities couple themselves with other natural entities and their activities. Emergence, therefore, is the radical geo-historicity of all earthly things, whose character is never given beforehand but constituted as they make their way through the world.

Varieties of dispositional essentialism about natural laws

An important task for metaphysicians and philosophers of science is to account for laws of nature – in particular, how they distinguish themselves from ‘mere’ regularities, and the modal force they are endowed with, ‘natural necessity’. Dispositional essentialism about laws (for short: ‘essentialism’) is roughly the view that laws distinguish themselves by being grounded in the essences of natural entities (e.g. kinds, properties). This paper does not primarily concern how essentialism compares to its main rivals – Humeanism and Armstrongeanism. Rather, it distinguishes and comparatively assesses various brands of essentialism – which mainly differ as to where exactly they take laws to find their essentialist sources (e.g. in particular entities, like electrons, or in larger pluralities of entities, or in the world as a whole), and what they take to be the targets of laws, namely what they apply to. Yet, this internal comparison is not unrelated to the more general debate about laws: the main criteria with which I compare these essentialist views concern how they can deal with some of the main objections faced by essentialism in general (the modal status it typically attributes to laws, which some think is too strong; and its alleged incapacity to account for the most 'general' laws, like conservation laws), and how they can keep what is arguably the main intuitive advantage of essentialism over its rivals (the fact that, on this view, things “govern themselves”). Thus, the paper also concerns the relative position of essentialism in the larger debate about laws – ultimately bringing support to it.

No fruits without color: Cross-modal priming and EEG reveal different roles for different features across semantic categories

Category-specific impairments witnessed in patients with semantic deficits have broadly dissociated into natural and artificial kinds. However, how the category of food (more specifically, fruits and vegetables) fits into this distinction has been difficult to interpret, given a pattern of deficit that has inconsistently mapped onto either kind, despite its intuitive membership to the natural domain. The present study explores the effects of a manipulation of a visual sensory (i.e., color) or functional (i.e., orientation) feature on the consequential semantic processing of fruits and vegetables (and tools, by comparison), first at the behavioral and then at the neural level. The categorization of natural (i.e., fruits/vegetables) and artificial (i.e., utensils) entities was investigated via cross–modal priming. Reaction time analysis indicated a reduction in priming for color-modified natural entities and orientation-modified artificial entities. Standard event-related potentials (ERP) analysis was performed, in addition to linear classification. For natural entities, a N400 effect at central channel sites was observed for the color-modified condition compared relative to normal and orientation conditions, with this difference confirmed by classification analysis. Conversely, there was no significant difference between conditions for the artificial category in either analysis. These findings provide strong evidence that color is an integral property to the categorization of fruits/vegetables, thus substantiating the claim that feature-based processing guides as a function of semantic category.

THE ARISTOTELIAN LEGISLATOR AND POLITICAL NATURALISM

Aristotle's assertion in Politics 1.2 that there is a natural impulse to form political communities is immediately contraposed with the claim that the person responsible for their foundation is the cause (αἴτιος) of the greatest of goods (Pol. 1253a33). The attribution of an essential role to the legislator as an efficient cause appears to clash, however, with Aristotle's political naturalism. If the polis exists by nature and humans are by nature political animals (1253a1–2), then the question arises as to why active intervention by the legislator is necessary for a polis. Conversely, if the polis is an artefact of practical reason, then Aristotle's distinction between products of the intellect and natural entities seems to preclude the status of the polis as natural. In light of this apparent tension between different aspects of Aristotle's account of the origins of political communities, the current paper seeks to demonstrate their reconcilability. Section 1 considers the role of the Aristotelian legislator in light of broader Greek assumptions regarding law-making. Section 2 then considers the status of law-making expertise (νομοθετική) as part of political science (πολιτική) and examines the mode of practical reason that is exercised by the legislative founder. Finally, in section 3, and building on recent interpretations which have emphasized that Aristotle operates with an extended teleological conception of nature, I argue that acts of legislative founding and nature can consistently serve as joint causes of the polis, because the ‘products’ of the practical rationality of the architectonic legislator are themselves an expression of distinctly human nature.

Of Ebbs and Flows: Understanding the Legal Consequences of Granting Personhood to Natural Entities in India

A study of the rights regime for environmental protection in India indicates that such protections overlap with constitutional rights guaranteed primarily to citizens or persons under the law. Contemporary jurisprudence has aggressively developed this intersectionality, declaring natural entities to be living persons with fundamental rights analogous to those of human beings. This article explores the role played by two judgments delivered by the Uttarakhand High Court – Mohammed Salim v. State of Uttarakhand and Lalit Miglani v. State of Uttarakhand – in the establishment of an effective framework for environmental protection. This is effectuated in both cases by assigning legal personality to rivers and articulating a conceptual shift from the human-centric approach. Accounting for the socio-cultural and spiritual relationships that have received legal protection, this article critically analyzes the judgments, their rationale and contributions to environmental protection. As the judgments articulate a paradigm shift in environmental protection, their effectiveness is best assessed through analyzing the frameworks created for their implementation. While the pronouncement of the Indian courts on the legal personality of rivers is an encouraging paradigm shift in environmental commitment, establishing the rights of nature was undertaken without due attention to the complexities that characterize the Indian socio-politico-religious context and to the legal consequences of bestowing vaguely contoured rights upon natural entities.

Ginger and Heart Health: From Mechanisms to Therapeutics

Background: As a major cause of morbidity and mortality, cardiovascular diseases (CVDs) are globally increasing. In spite of recent development in the management of cardiovascular complications, CVDs have remained a medical challenge. Numerous conventional drugs are used to play cardioprotective roles; however, they are associated with several side effects. Considering the rich phytochemistry and fewer side effects of herbal medicines, they have gained particular attention to develop novel herbal drugs with cardioprotective potentials. Amongst natural entities, ginger is an extensively used and well-known functional food and condiment, possessing plentiful bioactivities, like antiinflammatory, antioxidant, and antimicrobial properties in several disorders management. Objective: The current review deliberated phytochemical properties as well as the ginger/ginger constituents' biological activities and health benefits in several diseases, with particular attention to cardiovascular complications. Methods: A comprehensive research was conducted using multiple databases, including Scopus, PubMed, Medline, Web of Science, national database (Irandoc and SID), and related articles in terms of the health benefits and cardioprotective effects of ginger/ginger constituents. These data were collected from inception until August 2019. Results: In recent years, several herbal medicines were used to develop new drugs with more potency and also minor side effects. Amongst natural entities, ginger is an extensively used traditional medicine in several diseases. The crude extract, along with related pungent active constituents, is mostly attributed to heart health. The cardioprotective effects of ginger are contributed to its cardiotonic, antihypertensive, anti-hyperlipidemia, and anti-platelet effects. The signaling pathways and molecular mechanisms of ginger regarding its cardioprotective effects are also clarified. Conclusion: This study revealed the biological activities, health benefits, and cardioprotective properties of ginger/ginger constituents along with related mechanisms of action, which gave new insights to show new avenue in the treatment of CVDs.

Environmental resistance in the Anthropocene

Scientists describe the current “Anthropocene epoch” as one of profound anthropogenic disruptions in the ecosphere that place humanity at an unacceptable risk. This unprecedented ecological moment in human history is rooted in profoundly unsustainable patterns of production and consumption protected by liberal power structures expressed through law. The exigencies of the Anthropocene call us to expand the subjects of resistance to include future generations of humans, plants, non-human animals, ecosystems and “non-living” natural entities (such as water, air and climatic systems). Since these constituencies cannot resist in a socio-political sense, their representation in current socio-political systems will depend upon “an insurrection of subjugated knowledges” (Foucault 1980, 81) including Indigenous law, pre-modern holistic traditions of Western legal thought, and emerging theories of ecological law. This article will explore these approaches as possible paths forward in the Anthropocene, employing a comparative law perspective that considers relevant jurisprudence and policy developments from around the globe. Los científicos describen la época antropocena actual como una época de profundas perturbaciones antropogénicas en la ecosfera, situando a la humanidad ante un peligro inaceptable. Este momento ecológico hunde sus raíces en modelos insostenibles de producción y consumo, protegidos por estructuras de poder liberales. Las exigencias del Antropoceno nos urgen a incluir entre los sujetos de la resistencia a generaciones futuras de humanos, plantas, animales no humanos, ecosistemas y entes “no vivos” (como el agua, el aire y los sistemas climáticos). Como esas entidades no pueden ejercer resistencia en un sentido sociopolítico, su representación dependerá de “una insurrección de conocimientos subyugados” (Foucault 1980, 81), incluyendo leyes indígenas, tradiciones holísticas premodernas de pensamiento jurídico occidental y teorías jurídicas ecológicas emergentes. Este artículo examina tales enfoques, utilizando una perspectiva jurídica comparativa que toma en consideración jurisprudencia relevante y desarrollos de políticas en todo el mundo.
