Challenges on Urban Socio-Spatial Cohesion. The Case of Social Housing Complexes in the Regional Administrative area of Piraeus in Greece
Authors: Tousi Evgenia
Published: October 2021

The regional administrative area of Piraeus has long been a suitable case study for analyzing the impact of social housing. The six municipalities that constitute this urban agglomeration have been strongly connected with the Asia Minor Catastrophe of 1922 and the consequent rehabilitation of the refugee population during the 30s. Moreover, after WWII, more social housing complexes had been constructed in the urban area around central Piraeus, representing different architectural types and principles. Today, they host various socio-economic population groups. Economic immigrants and households of elderly people are some of the vulnerable households that reside today in the social housing apartments. One major issue is the poor housing conditions and the low level of preservation associated with high rates of poverty and social exclusion. This paper attempts to depict the contemporary situation in the area by providing thematic cartography with the aim of indicating crucial enclaves in need of urban regeneration.

Textile antennas are currently being researched and developed so that they can be integrated into clothing. In this paper, two textile antennas with cotton and silk substrate are presented. The antennas operate at GPS L1 frequency, which is 1.575 GHz. This paper discusses the effect of antenna parameters on free space and on-body conditions, and the effect of antenna bending. Based on simulation and measurement results, the parameter values obtained indicate that the antenna can operate properly at a frequency of 1.575 GHz and is safe to use on the body.
Die phänomenologische Metaphysik Marc Richirs
Authors: Schnell Alexander
Published: October 2021

Marc Richir (1943–2015) is one of the most authoritative phenomenologists of his generation with disciples all over the world. His importance, which has become increasingly evident in recent years, derives from his emphasizing of the imagination and fantasy in their symbolic function. In this way he opens up phenomenology to adopt perspectives that are no less interesting for artists than for poets or musicians. But his spectrum is even more extensive. As a trained physicist, Richir turned to problems of natural philosophy; at the same time, he was an excellent expert in structuralism, anthropology and psychoanalysis. But he was also very familiar with Classical German Philosophy, no less than with the thinking of the founding fathers of phenomenology, as well as with the influential approaches of Merleau-Ponty and Derrida. This book is the first monograph in the German language to present Richir's extensive work in all its scope. The question of a "phenomenological metaphysics" provides the guideline to testify to the openness of recent phenomenology to these wide-ranging topics.
Metaphern einer anderen Filmgeschichte
Authors: Engelke Henning
Published: October 2021

Dieses Buch eröffnet eine neue Perspektive auf eine der produktivsten, aber in der Forschung bislang vernachlässigte Phase experimenteller Filmproduktion an den Schnittstellen von Filmästhetik, Kunsttraditionen, sozialem Wandel und wissenschaftlichem Paradigmenwechsel. Auf der Grundlage von bislang unerschlossenen Quellen folgt das Buch den miteinander verwobenen Entwicklungslinien von ästhetischer Innovation, dem Streben der Experimentalfilmer um kulturelle Anerkennung und Institutionalisierung sowie den sich verändernden Konfigurationen technologischer Bildmedien. Kanonische Arbeiten von Filmemachern wie Kenneth Anger, Maya Deren, James Broughton oder den Brüdern John und James Whitney werden im Kontext von übersehenen, hier oft erstmals besprochenen Filmen betrachtet. Diese erweiterte Sichtweise stellt etablierte historische und theoretische Annahmen zum Experimentalfilm dieser Zeit grundsätzlich in Frage. Zugleich erschließt sie neue historische Kontexte, in denen sich Produktion, Rezeption und kritischer Diskurs zum Experimentalfilm entfalteten. Methodisch verbindet das Buch ästhetische Analysen und archivalische Forschung mit einem medienarchäologischen Ansatz, um die Relevanz des Experimentalfilms für eine historische Perspektivierung aktueller Diskurse zu Medienwandel und posthumanistischen Konzeptionen von Subjektivität aufzuzeigen.
Advances in Breeding of Peach, Plum and Apricot
Authors: Rimpika  , Sharma DP
Published: October 2021

Research on the expression of fruit specific genes may allow breeders in the future to selectively manipulate through gene transfer in certain aspects of fruit development/quality in their advanced breeding lines thus reducing the time necessary for cultivar development. This would be particularly useful in breeding programmes, hybridizing standard cultivars with exotic germplasm of low fruit quality. The use of exotic germplasm will be important for the expansion of the peach germplasm base and the development of stress resistant cultivars. More immediate results of research on fruit specific gene expression will provide a better understanding of fruit development and quality. It is required to learn how the differences at the gene level correlate with quality characteristics. With the continued cooperation of fruit biochemists it is expected to obtain a better definition of fruit quality and a better understanding of fruit biochemistry. The potential will exit to generate a range of “anti-sense mutants” i.e. transgenic plants expressing anti-sense gene contstructs that reduce or nullify the effects of the normal gene. The phenotypes of these mutants could help to define the biochemistry, genetics and quality of peach fruit. The development of efficient regeneration and transformation system in peach will be useful not only for the modification of fruit characteristics, but also for the transfer and manipulation of genes affecting stress resistance and other economically important characters.
Chemotherapy-Induced Peripheral Neuropathy: Mechanisms and Clinical Assessment
Authors: Casanova-Mollà Jordi
Published: October 2021

Antineoplastic drugs may be neurotoxic and the clinical features frequently include distal sensory loss and neuropathic pain. This is related to a direct damage in sensory neurons and non-selective degeneration of sensory nerve fibers. Due to different mechanisms, there are agents that affects also motor or autonomic nerves. In the case of immune checkpoint inhibitors, an inflammatory response attacks the muscle, motor neurons or neuromuscular transmission. We present an easy-to-read article to understand first symptoms of chemotherapy-induced neuropathy (CIN) with describing each agent and the course of neuropathy as well as the clinical assessment with neurophysiological techniques. In addition, skin biopsy allows us to examine histological changes such as reinnervation. Neuroprotection with antioxidant therapy is possible but more effort in this field is needed.

Authors: Zahid Qamar Sayyad , Akhtar Maaz , Pervez Tasneem
Published: October 2021

Oil and gas drilling and development is witnessing new and inventive techniques targeted at increased production from difficult and aging wells. As depth of an oil or gas well increases, higher temperatures and harsher environments are encountered. Suitable elastomers can provide good sealing as they possess good resistance to heat and chemical attack, and as they are widely availability at low cost. In comparison with metals, elastomers are lighter in weight and lesser in stiffness and hardness, swell more with increasing temperature, and are usually better in corrosion resistance. Other reasons for their preference include excellent damping and energy absorption, more flexibility and longer life; good sealing even with moisture, heat, and pressure; negligible toxicity; good moldability; and flexible stiffness. As mentioned in chapter-1, swelling elastomers or gels have found extensive use in different applications including drug delivery, microfluidics, biomedical devices, scaffolds for tissue engineering, biosensors, etc. As the main focus of this book is the oil and gas industry, implementation of swelling elastomer technology and deployment in different petroleum applications are discussed below.

Chemokines as Potential Biomarkers for PTSD in Military Population
Authors: Zhang Lei , Hu Xianzhang , Li Xiaoxia , J. Ursano Robert
Published: October 2021

Post-traumatic stress disorder (PTSD) is a serious mental health concern worldwide among civilians and military personnel. Gaps in our understanding of its biological basis create significant obstacles for accurate diagnosis and assessment of therapeutic interventions. In light of this, investigation of biological factors associated with possible molecular cues of inflammation or neuroimmune disorders, could provide new surrogate markers for PTSD or PTSD treatment response. Analyses to date in deployed military personnel have suggested that sets of chemokines may be useful as biomarkers for PTSD acquired in military operations. Specifically, studies to date suggest that CCL2, CCL15, CCL22, CCL25, CXCL2, and CXCL12 are associated with PTSD onset, while CCL13, CCL20, and CXCL6 are correlated to PTSD risk; CX3CL1 are associated with resilience; CCL3; CXCL11, and CXCL16 are associated with stress response. CCL11, CCL13, CCL20, and CCL25 are correlated with the severity of PTSD symptoms. This chapter reviews the current understanding of potential chemokine markers for PTSD, and the potential chemokines associated with PTSD onset, risk, resilience, as well as stress responses in service members. Although the proposed biomarkers require further validation, these findings may lead to additional knowledge for the education and development of diagnostic and therapeutic approaches for PTSD, not only benefiting military personnel, but civilians as well.
Clinical Management of DMD-Associated Cardiomyopathy
Authors: Lee-Gannon Theo , Lehrenbaum Hannah , Sheth Rahul , P.A. Mammen Pradeep
Published: October 2021

Over the past decade, cardiomyopathy has become the leading cause of mortality among patients with Duchenne muscular dystrophy (DMD). The majority of DMD patients over the age of 18 experience some degree of cardiac involvement. The primary cardiac manifestations of DMD include progressive left ventricular (LV) wall stress leading to LV dilatation and wall thinning, and the development of cardiac fibrosis, all of which culminate in decreased LV contractility and reduced cardiac output. Mortality in these patients is predominantly related to pump failure and fatal arrhythmias leading to sudden cardiac death. While basic guidelines for the management of cardiomyopathy in DMD patients exist, these recommendations are by no means comprehensive, and this chapter aims to provide further insight into appropriate clinical diagnosis and management of DMD-associated cardiomyopathy. Notably, earlier and more frequent cardiac assessment and care can allow for better outcomes for these patients. Pharmacological treatments typically include an angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker, beta-adrenergic receptor blockers, mineralocorticoid receptor antagonists, and corticosteroids. Non-pharmacological therapies include automated implantable cardioverter defibrillators and left ventricular assist devices, as well as in rare cases cardiac transplantation. Additionally, many emerging therapies show great promise for improving standards of care. These novel therapies, based primarily on applied gene therapy and genome editing, have great potential to significantly alter the DMD care landscape in the near future.
Finite element analysis of punching shear-unbalanced moment interactions at edge column-flat plate connections
Authors: Sudarsana Ketut , Gegiranang Wiryadi , Adi Susila
Published: October 2021

The unbalance moments at the edge connections of flat plate structures induced by lateral forces (i.e. an earthquake) may not always act in parallel directions of the building axes. Most research studied the unbalanced moments in one direction, a few of them in biaxial directions, and none of them in incline directions. This paper presents the results of a nonlinear finite element analysis on punching shear capacity at edge column-slab connections subjected to three directions of the unbalanced moments namely perpendicular, incline 45°, and parallel to the slab free edge in combination with the shear force. A 3-D numerical analysis of ten isolated edge column-plate connections was conducted by applying an appropriate element size, mesh, and calibrated material parameters of the concrete damage plasticity (CDP) model in ABAQUS. the connections were subjected to ten variations of the moment to shear (M/V) ratios. The results show that the punching shear capacity decreases exponentially for the unbalanced moment acting perpendicular and parallel to the slab free edge, and linearly for unbalanced moment incline 45° as the increase in M/V ratio. The M-V interaction at the edge connections depends on the unbalanced moment directions which are slightly different from the ACI 318 code.
“Mixed identity of circumstances”: Bronisław Malinowski in Australia and Melanesia
Authors: Kosecki Krzysztof
Published: October 2021

During his stay in Australia and Melanesia from 1914 to 1920, the anthropo- logist Bronisław Malinowski frequently experienced dichotomous and contradictory atti- tudes to people, places, and events: the contrast between the ‘civilized’ Australia and the ‘savage’ Melanesia; the background of the Austria-ruled Poland in which he grew up and the British-dominated Australia, Austria’s enemy in the First World War; the emotional tension of simultaneous attraction to two women – Nina Stirling of Adelaide and Elsie Rosaline Masson of Melbourne; the dilemma of the ‘heroic’ versus the ‘unheroic’ related to the war. Most of the dualities of Malinowski’s Australian-Melanesian experience, re- flected in letters to his mother Józefa Malinowska, Elsie R. Masson, and in Diary in the Strict Sense of the Term (1989), were resolved at the end of the period, which became a turning point in his life.
Identity, Fidelity, and Cross-Cultural Relationships in Joseph Conrad’s Almayer’s Folly
Authors: McParland Robert
Published: October 2021

Almayer’s Folly (1896) by Joseph Conrad challenged the conventions of the fictional romance while confronting the need of native-born Malayans and other Asian individuals to find voice and identity in an imperial context. Along with the narrative voice in this text are the many other voices of those who have been colonized. Fidelity to one’s identity and openness to relationships across cultures lies at the crux of this study. Conrad’s critics of the 1950s and 1960s dismissed his first novel as a romance with a weak subplot. However, that subplot, about Almayer’s daughter Nina and her love affair, sets forth moral claims of loyalty and fidelity that must be taken into account. For her relation- ship with a Malay prince expresses a love that is binding and enduring, one that crosses boundaries and divisions and is an apt model for our culturally convergent world. Conrad creates a dialectic of intercultural subjectivities to make a point about identity, loyalty, and self-fashioning. Whereas Almayer is portrayed as foolish and inflexible, his daughter, Nina, faces significant issues of identity, as she has to choose between the traditional, indigenous heritage of her mother and her father’s modern European aspirations. With Almayer’s Folly, Joseph Conrad showed himself to be an international novelist who could develop a story with an inter-racial and intercultural cast of characters.
On the Idea of the Secondary World in Susanna Clarke’s Piranesi
Authors: Błaszkiewicz Bartłomiej
Published: October 2021

The paper seeks to explore the concept of the secondary world as developed in Susanna Clarke’s 2020 fantasy novel Piranesi. The analysis is conducted in the context of the evolution of the literary motif of fairy abduction between the classic medieval texts and its current incarnations in modern speculative fiction. The argument relates the unique secondary world model found in Clarke’s novel to the extensive intertextual relationship Piranesi has with the tradition of portal fantasy narratives, and discusses it in the context of the progressive cognitive internalisation of the perception of the fantastic which has taken place between the traditional medieval paradigm and contemporary fantasy fiction.

Published: October 2021

A field experiment was conducted during kharif season of 2017 at Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur (Bihar) to investigate the “Effect of nutrient and weed management practices on weed dynamics and productivity of aromatic rice’’. The experiment was laid out in split-plot design and was replicated thrice. The treatments comprised three nutrient levels viz., N1= 100% RDF; N2=75% RDF + FYM 5 t/ha; N3=50% RDF + FYM 10 t/ha in main-plot, and six weed management practices viz., W1 = Brown manuring; W2= Bispyribac- sodium @ 25 g/ha as post emergence; W3= Chlorimuron ethyl + Metsulfuron methyl (Almix) @ 4 g/ha at 20 days after transplanting (DAT); W4= Pyrazosulfuron @ 25 g/ha; W5=Weed free; W6= Weedy check in sub-plot. The results revealed that treatment N1 recordedthe maximum- recorded the grain yield of rice. Among weed management practices, treatment W5 recorded the maximum grain yield of rice. Weed population and weed dry matter were found maximum in N3. Weed control efficiency and weed index was the maximum in W5 and W6 respectively. Thus, it may be concluded that the nutrient level N1 is superior to N2 & N3. Secondly, high cost involved in manual weeding makes herbicidal treatments more viable proposition. The weed management practice W2 is a most effective for transplanted aromatic rice.

Published: October 2021

Medicinal plants play an important role in curing various diseases, so the aim of this work was to conduct a study on the ethnobotanical survey of medicinal plants with students from the agronomy course at the Federal Institute of Pará Campus Castanhal. The methodology used to carry out the study was an interview, guided by a semi-structured questionnaire. After the information collected, the systematization of the data was carried out, followed by using medicinal plants of mixed, diverse and common use as classification criteria. The results obtained were that the interviewees have considerable knowledge about medicinal plants, mentioning 48 species of plants used for the treatment of various diseases, with plants standing out for diseases with symptoms of cough, flu, inflammation and diarrhea, with different forms of preparation, among the most cited were decoction, tea, bath and juice. Despite the diverse knowledge about the use of species for medicinal purposes, this knowledge over time is lost and needs to be recovered through ethnobotanical study.

Published: October 2021

Background: Drug interactions, which are generally encountered in medical prescriptions, may lead to severe health issues. Pharmacists in both the public and private pharmacy setting are by profession in a unique position to gain and use their competencies to find and prohibit drug interactions.

Aim of the Study: To assess knowledge, attitude and practice of pharmacists toward drug interactions in Saudi Arabia.

Materials and Methods: A cross-sectional study was conducted using a self- administered questionnaire.

Results: Two hundred sixty-three pharmacists participated in the survey and results were expressed in frequencies and percentages. The mean age of participant pharmacists was (31.7) years showing a relatively young participant’s population. Males were (75.3%), while females were (24.7%). Majority of pharmacists (67.3%) were working in public sector. Half of them had a bachelor’s degree in pharmacy as their latest academic degree.

Participants’ averages of awareness, attitude and practice regarding drug interactions, correct knowledge of drug-drug, drug-food, drug-disease interactions were, (90.7%), (65.3%), (67.7%), (61.7%) respectively. Most (79.8%) of the participants asserted that the notified doctors usually agree with pharmacists’ opinion and decision. This percentage indicates a good cooperation when compared to other studies.

Conclusion: Pharmacists’ knowledge about drug interactions was inadequate. Lack of knowledge of drug interactions may lead to improper patient counseling and the appearance of adverse effects. There is a need to improve the knowledge and to uplift the level of awareness of pharmacists about the potential drug interactions that are clinically related.

To find association between posttest musculoskeletal pain score among postpartum women with selected demographic variables in experimental and control group.

Materials and Methods: Quasi-experimental pretest posttest design is used to assess the effectiveness of postnatal exercises, among postpartum women in selected hospitals of Wardha. 80 sample size taken who fulfils the inclusion criteria, 40 postpartum women for control and 40 for experimental group with non-probability convenience sampling.

Expected Results: This study is planned to assess the effectiveness of postnatal exercises to the postpartum women experiencing musculoskeletal pain syndrome. Hence, it is expected to identify the level of pain and may reduce their level of pain.

The conclusion will be drawn from the results and will be published in per review journal.
“Quer me tributar, me chupar, foder-me porque sabe que é maravilhoso ser fresco” - A poesia-bicha de Paulo Augusto
Authors: Gomes Varjão João Victtor
Published: October 2021

Este ensaio pretende proceder a bicha nas poesias de “Falo” de Paulo Augusto (2003) para buscar um pensamento bicha. Busca-se acompanhar as linhas que a bicha traça, subverte e inverte em sua existência. Para isso, primeiramente, procura-se problematizar acerca dos dispositivos de gênero e sexualidade, problematizado por Foucault (2014), Preciado (2014) e Zamboni (2016), tendo a bicha como um sujeito desviante dos dispositivos. Para analisar a obra “Falo” de Paulo Augusto, utilizar-se-á, teórico-metodologicamente, do conceito de literatura menor, tomando as poesias-bichas como parte de um enunciado coletivo da bicha. A bicha, em “Falo”, se inscreve por meio do devir, desconstruindo territórios e ultrapassando identidades - a bicha problematiza identidades, conceitos, categorias – causa confusão epistemológica. A bicha traz problematizações acerca do aparelho do Estado e suas táticas de governabilidade – desembocando em problematização acerca de gênero e sexualidade. Além disso, a bicha contra-ataca a política e suas estratégias; tira sarro dos déspotas. A poesia-bicha de Paulo Augusto nos permite refletir acerca das construções identitárias que, embora se pareçam fixas e naturais, são construções advindas de um dispositivo discursivo complexo. Percebendo contradições na própria ciência, a bicha permite que se reflita acerca de categorias e metodologias científicas, em uma insistente problematização. A existência bicha pode permitir que seja feita descentralização do pensamento – um pensar de outro modo, um pensamento bicha.

Published: October 2021

Este artigo visa a analisar o discurso de um voto do Tribunal de Justiça do Estado do Tocantins sobre gênero, "ideologia de gênero" e o pânico moral que foram elementos basilares para declarar válida a Lei Municipal que proibiu qualquer discussão sobre gênero e sexualidade nas escolas de ensino fundamental de Palmas. Para tanto, discute o direito à educação como um direito humano fundamental, fazendo uma análise histórico-dialética sobre o Plano Nacional de Educação em vigor desde 2014, assim como desenvolve noções básicas sobre gênero, "ideologia de gênero" e pânico moral, entendendo estes últimos como fomentadores de discurso de discriminação e violência.
Tránsitos de género en Cuba: políticas públicas y migraciones género-disidentes.
Authors: Malfrán Yarlenis Mestre , Oliveira João Manuel de , Lago Mara Coelho de Souza
Published: October 2021

La idea de un género naturalizado como sexo e idealizado en la figura del héroe nacional, ha alimentado el imaginario cubano durante décadas, definiendo lealtades y deserciones. Este texto recurre a pesquisa bibliográfica, análisis de experiencias empíricas como un modo de colocar en diálogo diferentes historias de marginación de las disidencias de género en Cuba– las Unidades Militares de Apoyo a la Producción (UMAP), el éxodo del Mariel y la actual política trans. Nuestras reflexiones pretenden sumar al esfuerzo teórico-político de pensar otra ontología del género -como tránsito, como geografía -que permita imaginar políticas emancipadoras, teniendo en cuenta que las políticas cubanas fallan al comprender los tránsitos de género y consecuentemente, frenan estos procesos.

Masculinidades cisgêneras e os controles de acesso da comunicação heteroterrorista // Cisgender masculinities and the access controls of heteroterrorist communication
Authors: Silva Lucas Guerra da , Tchalian Vicente
Published: October 2021

O presente estudo objetivou descrever um modus operandi cisgênero de divulgação de notícias falsas com conteúdos que remetem a gênero e sexualidade, com vistas a reconhecer estratégias comunicacionais de manipulação heteroterrorista nas eleições presidenciais do ano de 2018 no Brasil. Para tanto, utilizamos a categoria “controladores de acesso”, de Raewyn Connell (2016), aprofundando-a em outros possíveis desdobramentos, ao observarmos o contexto político brasileiro contemporâneo, que garante (1) rito jurídico de legitimidade do lugar para candidaturas e conteúdos com possibilidade de veiculação; (2) o trânsito de conteúdos falsos condizentes com o imaginário de quem encontra respaldo nesse lugar legitimado, em função da possibilidade de candidaturas cujos discursos oficiais manifestam publicamente a abjeção por determinados conteúdos – que tem impacto e afetação na vida de pessoas; e (3) o comportamento dos veículos de comunicação mainstream que tiveram ferramentas construídas para desmentir as notícias falsas, ou que negligenciaram a construção de tais ferramentas, aproveitando-se também do lugar do legitimado. O referencial teórico visa construir uma narrativa sobre comunicação de guerra, encontrando na história do século 20 as funções que determinadas veiculações de conteúdos têm, quando encontram legitimidade nos lugares dados como possíveis de pertencimento; e como essa história é, na realidade, história do presente, apresentando-se em roupagens outras no século 21, em um contínuo ancestrofuturista. Aqui, circunda todo o texto a comunicação na pós-humanidade, em que há complexas tramas comunicacionais e circulação de informações multiplataformas que nos constituem em hibridez humano-máquina. Os aspectos metodológicos contaram com (1) coleta e sistematização das notícias veiculadas durante o período selecionado, bem como (2) imagens (prints) feitas a partir das plataformas comunicacionais mainstream estudados (o tecnohabitat): as ferramentas Fato ou Fake, das Organizações Globo, e seus compartilhamentos no Facebook; com vistas a oferecer a possibilidade de o/a leitor/a visualizar efetivamente os formatos e diagramações das notícias em questão, considerando também a estética da comunicação como reflexão de análise. Por fim, a categoria de análise que propusemos e intitulamos “controladores de acesso da agenda pública” mostrou-se útil para pensar as relações entre cisgeneridade, branquitude, masculinidade e os espaços de trânsito comunicacionais, sobretudo, no que tange os aspectos políticos e sociais da vida pública que espetacularizam-se como nunca; e, como nunca, nos afetam. Palavras-chave: Masculinidades; Cisgeneridades; Controle de Acesso; Agenda Pública.
Masculinidades negras em disputa: Autenticidade racial e política de respeitabilidade na representação da homossexualidade negra masculina // Black masculinities in dispute: Racial authenticity and respectability policy in the representation of black male
Authors: Bibiano Matheus Vieira Gomes
Published: October 2021

A partir do caso de Lionel Higgins, da série Dear White People (Netflix, 2017–2019), este artigo se concentra na crítica à refutável dicotomia entre negritude e homossexualidade produzida a partir uma concepção de autenticidade sobre o signo negro e suas implicações na produção de representações da homossexualidade do homem negro na televisão americana. Nas palavras de Devon Carbado (2017), há uma racialização da homossexualidade masculina como branca e uma pretensa condição ontológica da negritude como heterossexual que marginalizam e invisibilizam gays e lésbicas negros tanto na sua identidade racial quanto na sexualidade. São abordadas aqui considerações sobre a condições de produção de representações da homossexualidade do homem negro e suas implicações.

O futuro é coisa de criança: teoria queer, desidentificação e a pulsão de morte
Authors: Edelman Lee
Published: October 2021

Neste ensaio, Lee Edelman articula psicanálise lacaniana e desconstrução para esboçar uma ética radicalmente negativa para a teoria queer. Seu alvo principal é a figura onipresente da Criança, que o autor entende como a insígnia máxima da lógica universalizante do “futurismo reprodutivo”. Edelman argumenta que essa Criança representa a promessa de um futuro sem espaço para o queer, entendido como a personificação de uma pulsão de morte implacável, narcisista e antissocial. O autor insiste que a potência da queeridade reside em sua própria disposição a abraçar essa recusa da ordem social e política, materializada na ironia, no gozo e, em última instância, na própria pulsão de morte.
Instant Intracellular Delivery of miRNA via Photothermal Effect Induced on Plasmonic Pyramid Arrays

Published: October 2021

MicroRNA (miRNA) therapeutics are a promising cancer treatment approach with high efficacy and low side effects. Although substantial progress regarding pharmacokinetics and pharmacodynamics of miRNAs is made, it remains challenging for effective and harmless intracellular delivery. In this study, instant and efficient intracellular delivery of miRNA against esophageal cancer via photothermal effects induced on plasmonic pyramid arrays is reported. An instantaneous high temperature can be generated (≈470 °C) on a plasmonic pyramid after laser stimulation (≈8 μs @640 nm), which is enough to disrupt the cell membranes to facilitate intracellular delivery of biocargos like miRNA. Within ≈150 μs after removal of laser stimulation, the pyramid temperature would decrease to ≈37 °C to avoid cell damage. By this approach, intracellularly delivery of miRNA‐185 to Taxol‐resistance esophageal cancer cells is successfully achieved within minutes with decent delivery efficiency (64%) and cell viability (>95%) are observed after optimization. Moreover, for combating drug resistance, 61.9% of KYSE30/Taxol cell is inhibited after laser‐stimulation via the combined effects of miR‐185 and Taxol with efficient intracellular delivery. This study provides a convenient intracellular delivery approach for large biocargos and a possible solution for overcoming cancer drug resistance.

Membranes with fast and selective ion transport have great potential for use in water‐ and energy‐related applications. The structure and material design of the membranes play a key role in improving their performance. Conjugated microporous polymers (CMPs) as emerging membrane materials have shown uniform pore size, high surface area, and excellent chemical stability, but their mechanical properties are poor due to their brittleness. Herein, a flexible ionic CMP membrane with precisely tailored pore architecture and chemistry prepared by a coelectropolymerization (COEP) strategy is reported. The structure contains rigid monomers to maintain structural uniformity and flexible and charged monomers to enhance mechanical flexibility and improve ion selectivity by combining precise size sieving and Donnan effect. The resulting 40 nm thick CMP membranes show equivalent ion conductance compared to the commercial Nafion 117 membrane, but an order of magnitude higher ion selectivity for ion systems such as K+/Mg2+ and Li+/Mg2+.

Gold nanocomplexes have been proposed as contrast agents for computerized tomography (CT) and cell tracking, which is especially useful in stem cell therapy. However, their potential for long‐term in vivo cell detection is still unknown. This study proposes an optimized approach to labeling human periodontal ligament stem cells (hPDLSCs) with gold nanocomplexes to evaluate their detection with micro‐CT after transplantation at four different rat tissues. The gold nanocomplexes of 0.05 mg mL−1 do not affect cell viability nor osteogenic differentiation capacity, but render fluorescent and radiopaque hPDLSCs. Excellent linear correlation with the number of labeled cells is shown over a wide range (r = 0.99, P < 0.01), with a detection limit of ≈1.2 × 103 cells/µL. In vivo, strong, and durable detection of transplanted labeled cells within 5 days at all investigated areas is seen by micro‐CT and immunohistochemical assay. This approach confirms the potential of gold nanocomplexes in longitudinal in vivo cell tracking, which may facilitate their application in CT image‐guided interventions commonly used in oromaxillofacial or systemic applications of stem cell therapy.

Nature demonstrates many examples of response and adaptation to external stimuli. Here, this study focuses on self‐propulsion (motion) while presenting several self‐propelling droplet systems responsive to pH gradients. Light is used as the gating source to gain reversibility, avoid the formation of chemical wastes, and control the self‐propulsion remotely. To achieve light‐stimuli ultrafast response, photoacids and photobases are used, capable of donating or capturing a proton, respectively, in their excited state. The movement and directionality of the droplet's self‐propulsion are controlled by introducing the photoacid/base either in bulk solution, on the surface of the droplet, or inside the droplet. It is shown that proton transfer between the photoacid/base and the droplet results in a rapid change in the droplet's surface tension, which induces the self‐propulsion movement. The high versatility of the systems together with a record‐breaking ultrafast response to light makes them highly attractive for the design of various controlled cargo‐carrier systems.

Design and engineering of novel low dimensional metamaterials allow for new applications in membrane technology, aerospace and automotive industries, architecture, robotics, medicine, and textiles. Such materials can be strong, flexible, transparent, and can be assigned with different functionalities. Here, the authors explore the possibility of 2D graphene oxide (GO) surface to guide self‐assembly of 4‐cyano‐4′‐pentylbiphenyl (5CB) molecules via multiple hydrogen bonding and their clustering in optically active phases. The encapsulation of 5CB in a 2D geometry and birefringent properties of 5CB are tuned by the regulation of interaction energy between GO surface and 5CB. Chemical reduction of GO‐5CB composites results in electrically conductive reduced graphene oxide‐5CB membranes which change optical properties in response to Joule heating. The sustainable approach to the design of robust and flexible optically active materials will allow the formation of other metamaterials with different functionalities for advanced applications.
Flexible Janus Functional Film for Adaptive Thermal Camouflage

With the increasing development of infrared (IR) detection technologies for both military and civil applications, IR anti‐detection technologies, also known as thermal camouflage technologies, have attracted great attention in recent years. Decreasing the surface emissivity may be effective for high‐temperature targets, but fails for adaptive thermal camouflage in dynamic scenes where the background temperature varies. In this work, we demonstrate a flexible Janus functional film (JFF) for adaptive thermal camouflage. The JFF consists of a low emissivity (low‐ε) layer and a high heat capacity (high‐C) layer. The low‐ε layer can effectively suppress the IR radiation of the objects, thus reducing the temperature of the objects in IR camera, while the high‐C layer can make similar thermal response as the background. According to different environmental conditions, different surfaces of JFF can be selected as camouflage surface to achieve static or dynamic thermal camouflage effect. What's more, the substrate materials of JFF (i.e., high‐density polyethylene (HDPE), silica gel (SG)) enable the film with good flexibility and realize the encapsulation of the functional filler, thus improving its reliability of resisting water and oxygen. Such flexible JFF with high reliability, easy scalability, and low cost may hold great promise for broad applications in adaptive thermal camouflage.
The Compliance Conversation: Navigating Variations in Sterile Processing Practices

Because of the variety of guidelines for instrument processing and sterilization (eg, government regulations on infection prevention and control [IPC], manufacturers’ instructions for use, publications from professional organizations), practices may vary from one country or facility to another. The Joint Commission recommends that when creating or revising IPC‐related policies, organizations should use a hierarchical model to address relevant IPC requirements. Joint Commission International accredits health care organizations outside the United States using standards and a survey process similar to, but not the same as, The Joint Commission. During a survey, perioperative nurses should use facility policies and procedures to provide evidence of compliance with regulations, guidelines, and best practices for surgical instrument processing. This article provides an overview of national and international IPC guidelines, the hierarchical models for organizations to use to update policies at their facilities, and differences in sterilization load release practices inside and outside the United States.

The intrinsic kinetics of the methanol dehydration to dimethyl ether over the laboratory‐synthesized and commercial γ‐alumina is studied. A set of kinetic models admitting different mechanisms of the reaction is developed. The developed kinetic models, as well as the kinetic models of the methanol dehydration presented in the literature, are experimentally verified. It is shown that the kinetic model admitting Langmuir–Hinshelwood mechanism with associative methanol adsorption is the only model which describes intrinsic methanol dehydration rate over either laboratory or commercial γ‐alumina catalyst. The estimated activation energies are 121 and 128 kJ/mol, methanol adsorption heats are 45 and 70 kJ/mol, and methanol adsorption entropies are 72 and 131 J/(mol × K) for the laboratory and commercial samples, respectively. The laboratory‐synthesized γ‐alumina may be successfully used for modeling and scaling the process that utilizes the commercial γ‐alumina catalysts.

Published: October 2021

Many water systems are challenged with uncertainty regarding service line material type. This work investigated using a simple drinking water flushed sampling approach and a more complicated and invasive sequential profile sampling approach to predict whether homes had an existing lead service line (LSL). Homes that never had an LSL (control groups) and homes with LSLs (study groups) in two communities having different degrees of corrosion control were sampled. Using control groups' results, community‐specific “threshold” lead levels were determined and compared to results from study groups. The flushed sampling maximum lead concentration (FMC) of lead accurately predicted 100% and 60% of LSL sites for the community with poor and good corrosion control, respectively. The weighted average sequential profile lead concentration (WASLC) increased the 40% not identified as LSL sites by fully flushed samples to 100%. The WASLC closely followed by the maximum sequential profile lead concentration were most reliable in identifying LSLs.
