In this essay we talk about environments and agencies and how they are, adversely, in the mainstay of the current idea of transdisciplinarity, multidisciplinarity and transgression in university ...doing that tends to be disciplinary, monocratic and conservative, because, strictly speaking, the so-called academic requires a conceptualization of knowledge in the simulacrum of having a 'research object'. Thus, we want to emphasize that epistemic practice is colonized and its power is given to those who have power and therefore we dare to walk under labyrinths, in the cracks, between blurs of things not established, sometimes denied but potent in creativity and also imaginative. We start from a proper and appropriate reflexive perspective and tend to present provocations that can contribute to the already well-established discussion of thinking about human and non-human relations. To this end, we review the thought of Tim Ingold, a British anthropologist who has made an important contribution to this discussion in contemporary times. Finally, we highlight essayistic dynamics to think about a relationship between epistemology and the concept of agency, taking as a challenge to reflect on how environments are continually in formation due to the activities of human and non-human creatures; the evolution of form is a situated activity of these beings; and that it is in the entanglements of experience, notes, sketches and imagination that we understand the environment. Keywords: agencies; experience; entanglements; Tim Ingold. Neste ensaio falamos em ambientes e agencias e como eles se encontram, adversamente, no esteio da ideia corrente de transdisciplinaridade, multidisciplinaridade e transgressao em fazer universitario que tende a ser disciplinar, monocratico e conservador, pois, a rigor, o dito academico exige uma conceitualizacao do saber, no simulacro de se ter um 'objeto de pesquisa'. Assim, nos queremos destacar que o fazer epistemico e colonizado e seu poder e dado a quem tem poder e, portanto, ousamos caminhar sob labirintos, nas frestas, entre borroes de coisas nao estabelecidas, as vezes negadas, mas potentes em criatividade e tambem imaginativas. Partimos de uma perspectiva reflexiva propria e apropriada e tendemos a apresentar provocacoes que possam contribuir com a discussao ja bem estabelecida do pensamento sobre as relacoes humanas e nao-humanas. Para tanto, passamos em revista o pensamento de Tim Ingold, antropologo britanico que tem contribuido de forma importante para essa discussao na contemporaneidade. Finalmente, destacamos a dinamica ensaistica para pensar uma relacao entre a epistemologia e o conceito de agencia, tomando como desafio refletir sobre como os ambientes estao continuamente em formacao devido as atividades das criaturas humanas e nao-humanas; a evolucao da forma e uma atividade situada destes seres; e que e nos emaranhados da experiencia, notas, rascunhos e imaginacao que compreendemos o ambiente. Palavras-chaves: agencias; experiencia; emaranhados; Tim Ingold.

Researchers worldwide are taking advantage of novel, commercially available, technologies, such as ion mobility mass spectrometry (IM‐MS), for metabolomics and lipidomics applications in a variety of ...fields including life, biomedical, and food sciences. IM‐MS provides three main technical advantages over traditional LC‐MS workflows. Firstly, in addition to mass, IM‐MS allows collision cross‐section values to be measured for metabolites and lipids, a physicochemical identifier related to the chemical shape of an analyte that increases the confidence of identification. Second, IM‐MS increases peak capacity and the signal‐to‐noise, improving fingerprinting as well as quantification, and better defining the spatial localization of metabolites and lipids in biological and food samples. Third, IM‐MS can be coupled with various fragmentation modes, adding new tools to improve structural characterization and molecular annotation. Here, we review the state‐of‐the‐art in IM‐MS technologies and approaches utilized to support metabolomics and lipidomics applications and we assess the challenges and opportunities in this growing field.
The Left Behind series by Tim LaHaye and Jerry B. Jenkins has become a popular culture phenomenon, selling an astonishing 40 million copies to date. These novels, written by two well-known ...evangelical Christians, depict the experiences of those left behind in the aftermath of the Rapture, when Christ removes true believers, leaving everyone else to suffer seven years of Tribulation under Satan's proxy, Antichrist.
In Marks of the Beast , Shuck uncovers the reasons behind the books' unprecedented appeal, assessing why the novels have achieved a status within the evangelical community even greater than Hal Lindsey's 1970 blockbuster The Late Great Planet Earth . It also explores what we can learn from them about evangelical Christianity in America.
Shuck finds that, ironically, the series not only reflects contemporary trends within conservative evangelicalism but also encourages readers—especially evangelicals—to embrace solutions that enact, rather than engage, their fears. Most strikingly, he shows how the ultimate vision put forth by the series' authors inadvertently undermines itself as the series unfolds.
•Improving PV-TEG efficiency by tackling metal surface and air gap thermal challenges.•Proposing mathematical modeling for predictive performance evaluation of PV-TEG systems.•Investigating the ...effectiveness of PGS as a TIM in PV-TEG systems.•Assessment of three cooling approaches: natural air, forced air, and forced water.•Bent PGS configuration proves most effective in reducing PV panel temperature to enhance power generation.
PV-TEG systems utilize waste heat by using TEGs under PV panels. TEGs improve the efficiency of PV and generates more energy. However, rough metal surfaces at contact points reduce the system's thermal efficiency and create air gaps. This paper employs a mathematical model based on principles of thermal resistances and energy conservation. The proposed model is built using MATLAB R2020a. The paper assessed the effectiveness of a Pyrolytic Graphite Sheet (PGS) as a Thermal Interface Material (TIM) in PV-TEG systems and three cooling approaches. The investigation explores two configurations (parallel and bent) of PGS and five TIM materials. The results indicate that bent PGS is the most effective. It lowers the temperature of the PV panels to 18.99 ℃, 19.95 ℃, and 20.74 ℃. As a result, the power increased to 0.606 W, 0.639 W, and 0.667 W. Additionally, the efficiency improves to 1.66 %, 1.75 %, and 1.82 % with natural air, forced air, and forced water cooling, respectively. The results show that PGS can improve PV-TEG system performance and solve thermal issues with metal surfaces and air gaps.
Vietnam and Beyond: Tim O’Brien and the Power of Storytelling is a comprehensive, in-depth study of one of the most thought-provoking writers of the Vietnam war generation. This volume breaks away ...from previous readings of O’Brien’s development as a trauma artist and an outspoken chronicler of the American involvement in Vietnam: its thematic, rather than chronological, approach contextualizes O’Brien’s work beyond the confines of war literature. The necessary exploration of O’Brien’s recurrent engagement with the conflict in Vietnam leads to a thorough discussion of the writer’s revision of key American (and western) ideas and concerns: the association between courage, heroism and masculinity, the celebration of the pioneering spirit in the frontier narrative, the sense of superiority in the encounter with foreign civilizations, the fraught relationship between power and truth, or reality and imagination, and the attempt and the right to speak about unspeakable events. All these themes, as Ciocia illustrates, highlight O’Brien’s compelling preoccupation with the role and the ethical responsibility of the storyteller. With his clear privileging of ‘story-truth’ over ‘happening-truth’, O’Brien makes a bold, serious investment in the power of fiction, as testified by his formal experimentations, metanarrative reflections and sustained meditations on matters such as individual agency, moral accountability and authenticity. Approached from this fresh perspective, O’Brien emerges as a figure deserving to find a wider audience and demanding renewed scholarly attention for his remarkable achievements as a contemporary mythographer, an acute observer of the human condition and a sharp critic of American culture.
Hydrolytic enzymes are highly demanded in the industry. Thermostability is an important property of enzymes that affects the economic costs of the industrial processes. The rational design of GH10 ...xylanase E (XylE) Penicillium canescens for the thermostability improvement was directed by ΔΔG calculations and structure analysis. Amino acid substitutions with stabilizing values of ΔΔG and providing an increase in side-chain volume of buried residues were performed experimentally. From the six designed substitutions, four substitutions appeared to be stabilizing, one – destabilizing, and one – neutral. For the improved XylE variants, values of Tm were increased by 1.1–3.1 °C, and times of half-life at 70 °C were increased in 1.3–1.7-times. Three of the four stabilizing substitutions were located in the N- or the C-terminus region. This highlights the importance of N- and C-terminus for the thermostability of GH10 xylanases and also enzymes with (β/α)8 TIM barrel type of structure. The criteria of stabilizing values of ΔΔG and increased side-chain volume of buried residues for selection of substitutions may be applied in the rational design for thermostability improvement.

•A fully recyclable TIM with high thermal conductivity and conformability to the rough surface was prepared.•Filled BN could be oriented by hot-pressing and led to a thermal ...conductivity of 3.85 W·m−1·K−1, 4.3 times higher than the composite before hot-pressing treatment.•BN recovery rate of 96.2% and other organic raw materials recovery rate of 73.6% to 82.4% were achieved.•The electronic device made of the prepared composite exhibited a 20 °C lower core temperature than the commercial silicone material.
Thermal interface materials (TIMs) with excellent heat dissipation capacity are highly desired for the development of miniaturized, integrated, and dense electronic devices. In addition, with the increasing accumulation of e-waste, the recyclability of TIMs has also become an urgent concern. Herein, a fully recyclable TIM with high thermal conductivity and conformability to the rough surface was prepared based on the synthesized epoxy vitrimer and boron nitride (BN) nanosheet. Results revealed that only by simple hot-pressing, the filled BN could be easily oriented in the plane and led to a thermal conductivity of 3.85 W m−1 K−1 with the BN content of 40 wt%, which was 30 times higher than that of the pristine epoxy resin and 4.3 times higher than the composite before hot-pressing treatment. The electronic device made of the prepared composite exhibited a 20 °C lower core temperature than the commercial silicone material, due to the superior thermal conduction and mechanical compliance. Moreover, benefiting from the multistage degradation mechanism of the synthesized epoxy vitrimer, the fabricated composite could be efficiently chemically recovered under mild conditions, demonstrating the BN recovery rate of 96.2% and other organic raw materials recovery rate of 73.6% to 82.4%. This work provides us with a new strategy for the design of recyclable and high-performance TIMs.
