The Aerodynamics of F1 Car Design
Authors: Pandit Arnav , Day Gwyn 
Published: July 2021

Formula One (also known as F1) is the highest class of single-seater open-wheel and open-cockpit professional motor racing contest. Formula One racing is governed and sanctioned by a world body called the FIA − Fédération Internationale de l'Automobile or the International Automobile Federation. The name ‘Formula’ comes from the set of rules that the participating cars and drivers must follow. The car is naturally the central component in F1.
There is not much room to differentiate in the design of the engine and wheels of F1 cars, there are only 4 engine manufacturers and Pirelli is the sole supplier for all team’s tyres. As there is not much scope for innovation in these aspects of an F1 car, most innovation is left to the aerodynamic design of the F1 car. The aerodynamics team considers many different principles when designing the car. In this paper, we will be first examining these aerodynamic principles and then discussing how they are applied to F1 cars.
A survey has also been conducted among over 200 professionals/academics involved in STEM to get an idea of people’s opinions on F1 Car Aerodynamics. The data collected has been analysed to see if it agrees with the reality. While there are many papers have already been written on F1 Aerodynamics, this is the first to provide one in relation to the specific parts. It is also the first to conduct a survey among people and provide analysis for the same.
A review of the primary nutritional and environmental factors associated with Parkinson’s disease
Authors: Considine Eleanor , Yin Lucy , Hartmann Mitra 
Published: July 2021

Parkinson’s disease is a progressive nervous system disorder that produces both motor and nonmotor symptoms. This literature review begins by examining evidence for several possible origins for the disease: does it begin in the brain and progress to the gut, or vice versa, or does it begin in both places concurrently? Next, we examine several environmental factors that have been shown to either increase or decrease risk of Parkinson’s disease. These are primarily nutritional factors, specifically caffeine, nicotine, and dairy products. Studies in both animals and humans provide weak evidence that increased consumption of low fat dairy is associated with an increased risk of Parkinson’s disease development. Additionally, there is strong evidence that nicotine has a neuroprotective effect which also lowers the risk. Finally, there is similarly strong evidence that caffeine exerts neuroprotective effects which lower the overall risk of developing Parkinson’s disease.
Dyslexia and Auditory Processing Disorder: A Neurological Chicken or Egg Debate?
Authors: Summe Isabella , McCoy Terry 
Published: July 2021

An estimated 10 million students in the United States have dyslexia and of those students, 2.5 million are estimated to have auditory processing disorder. There is an ongoing debate on whether auditory processing disorder causes or contributes to dyslexia or the disorders are just co-morbid. This paper examines dyslexia and auditory processing disorder and then considers current research on the nature of the relationship between the two disorders.
How does the pH of a solvent influence the solubility of turmeric in it?
Authors: Bansal Miyu , Sivakumar Uma 
Published: July 2021

Turmeric is a culinary spice used in many meals particularly in traditional Indian cuisine. Turmeric has a bright orange colour that is due to the presence of curcumin within it. Because of it’s bright colour, it is important to be able to easily remove turmeric stains from clothing. In my research I attempted to find the ideal conditions for removing turmeric stains and found that no investigation had been made into the impact the pH of the cleaning agent on its effectiveness.
In this investigation the solubility of turmeric in 5 different solutions was found using colorimetry. Colorimetry is a scientific technique that is used to determine the concentration of coloured solutions by the application of the Beer-Lambert law. This method allowed the solubility of turmeric to be determined, in a range of different solvents with good accuracy and precision. The experimental results showed that turmeric was more soluble in solutions with higher pH levels as the solubility in 0.2M sodium hydroxide was 17.6mg/mL and in pure ethanol was 10.1mg/mL, while the solubility in hydrochloric acid was only 0.034mg/mL.
Ultimately, this investigation shows that turmeric is more soluble in basic solutions and hence basic solvents are more effective removers of turmeric stains. A claim which was shown to be true by washing turmeric stained clothes with the solvents and comparing the cleaned clothes. This investigation also shows that turmeric could be used as a pH indicator as it has a different colour in different pH solutions.

Pendidikan Islam didefinisikan sebagai proses transformasi dan internalisasi ilmu pengetahuan dan nila-nilai pada diri anak didik melalui penumbuhan dan pengembangan potensi fitrahnya guna mencapai keselarasan dan kesempurnaan hidup dalam segala aspeknya. Dalam pelaksanaannya terdapat beberapa problem yang menyebabkan gagalnya sebuah capaian dari Pendidikan Islam. Problem tersebut terbagi dua macam, yakni problem internal dan problem eksternal. Untuk menanggulangi berbagai problem dalam pelaksanaan Pendidikan Islam tersebut, salah satu jalan yang dikeluarkan oleh Negara ialah dengan memberikan peluang yang cukup luas terhadap Pendidikan Islam melalui penetapan urgensi perannya di Undang-Undang Sistem Pendidikan Nasional.
Sebelum penetapan itu masih dikenal dengan dualism sistem pendidikan nasional, yang mana hal ini merupakan sebuah kesinambungan sejarah, baik sejarah pada umat Islam pada khususnya maupun sejarah bangsa Indonesia pada umumnya. Di samping itu, wacana dualisme sistem pendidikan kembali menguat akibat gejolak politik nasional yang berisi sebuah ideologi tertentu. Apapun alasannya, dualisme banyak berdampak negatif terhadap lembaga pendidikan di Indonesia terlebih lembaga pendidikan Islam.

Refutar el tiempo
Authors: Cisternas Cruz Cristian Enrique 
Published: July 2021

En este artículo proponemos que en la obra literaria de Jorge Luis Borges existe una preocupación por los fines y los límites del tiempo, que ha sido abordada, desde diversos enfoques teórico-metodológicos, por sus comentadores. Este preocupación incide notablemente en el desarrollo estilístico y en el interés temático posibles de advertir en la escritura de Borges. El propósito de este artículo es iluminar las vías de orientación que genera su escritura literaria en pensadores tales como Maurice Blanchot, Michel Foucault, Gilles Deleuze y Félix Guattari. El diálogo entre literatura y filosofía es, consecuentemente, clave en este artículo, que pretende además, a partir de una serie de ejemplos de la escritura narrativa y ensayística del escritor argentino, re-instalar la preocupación por el tiempoÂ dentro del marco de la reflexión sobre la escritura borgeana
MicroRNA-200a inhibits TGF-β-induced epithelial-mesenchymal transition in human ovarian carcinoma cells by downregulating SOX4 expression
Authors: Ren Ziyao , Hu Yonghua , Chen Jian , Jin Lanying 
Published: July 2021

IntroductionThe microRNA-200 (miR-200) family and sex-determining region Y-box 4 (SOX4) could regulate EMT phenotypes, which is important to the process of tumor pathological. This study explored the association of miR-200a with SOX4 in transforming growth factor (TGF)-β-induced EMT of OC cells.Material and methodsFor the in vitro experiments, hunam CO cells subjected to TGF-β was used to induce EMT; the activity of miR-200a was selectively inhibited or overexpressioned by miR-200a inhibitor and mimics, respectively. Small interfering RNAs against SOX4 (si-SOX4) were used to inhibit SOX4 expression in human OC cell lines.ResultsDecreased miR-200a and increased SOX4 levels were detected in patients with OC and these changes were closely related to the International Federation of Gynaecology and Obstetrics stage, ovarian tumor biomarker CA125 level, lymph node status and tumor size. The TGF-β-treated cells increased the miR-200a level, decreased the SOX4 level and prompted EMT properties, including a reduction in epithelial marker (e-cadherin), induction in interstitial markers (vimentin and n-cadherin), and enhancement of proliferation, migration and invasion. The OC cells were transducted with miR-200a mimic and the overexpression cells were subsequently treated with TGF-β, decreased SOX4 expression and EMT properties were detected. Also, in miR-200a inhibited cells, TGF-β increased SOX4 expression and EMT properties. Moreover, SOX4 silencing weakened the effect of the miR-200a inhibitor.ConclusionsOverall, these results provide a link between miR-200a and SOX4 in OC pathogenesis and indicate that miRNA-200a inhibits EMT by downregulating SOX4 expression in human OC cells.

“Acordamos, somos cidadãos”: os evangélicos e a constituição ética de si na relação com o político
Authors: Mauricio Junior Cleonardo Gil De Barros 
Published: July 2021

Este trabalho tem como objetivo principal compreender a forma como os crentes pentecostais constituem-se a si mesmos como sujeitos na relação com a política. Levando em consideração os embates públicos ocorridos na esfera pública brasileira em torno das questões relativas aos direitos sexuais e reprodutivos, e que colocaram em lados opostos igrejas pentecostais e movimentos sociais, afirmo que os fiéis ordinários dessas igrejas têm recebido de seus líderes a incumbência moral de se posicionarem politicamente em suas vidas cotidianas na defesa de temas caros aos seus sistemas de valores. “Crente também é cidadão” e, por isso, “tem de se posicionar” é o que recomenda aos seus liderados o pastor Silas Malafaia, um dos líderes pentecostais mais polêmicos no que diz respeito aos embates contra os movimentos sociais. Diante desse novo código moral, que chamo de pentecostaharsh, no qual uma cidadania política é atrelada à constituição de um sujeito religioso, pretendo saber como se dá esse processo, que chamo de constituição do crente-cidadão, no dia a dia dos fiéis e em suas relações fora da igreja. Para dar conta da constituição do crente-cidadão, realizei trabalho de campo com observação participante na sede nacional da Assembleia de Deus Vitória em Cristo, localizada no bairro da Penha, na cidade do Rio de Janeiro, a igreja do pastor Silas Malafaia. Participei das reuniões de um grupo específico, o Universe, responsável por debater a vida cristã na universidade e munir os jovens de argumentos legítimos para discutirem e defenderem os pontos de vista da igreja em suas respectivas faculdades. Com isso, pretendo mostrar como os jovens crentes da igreja de Malafaia dão conta dessa missão em suas vidas cotidianas, principalmente na faculdade, e definem a sua conduta ética em meios às tensões políticas que têm caracterizado a sociedade brasileira atualmente.
O Aurora e Prática do Sem Preço: Reflexões sobre Política, Infraestrutura e Dinheiro na Vida Ordinária
Authors: Neves Yuri Rosa 
Published: July 2021

O presente artigo faz uma análise sobre o ato de pagar a partir da discussão antropológica sobre infraestrutura. Mais especificamente, se apoia em ferramentas conceituais que apontam para a dimensão ordinária, banal e invisível com a qual as infraestruturas se revelam para as pessoas em suas interações. A reflexão enriquecida por um caso empírico em que este itinerário burocrático de consumo, pagar por algo, acontece de modo diferente: trata-se de um restaurante em que a refeição não tem um preço fixo, pré-estabelecido ou mesmo sugerido. O Aurora propõe o “sem preço” como uma prática “corresponsabilização e apoio mútuo” por entenderem o valor relativo do dinheiro em nossa sociedade. O efeito de contraste que tal experiência engaja permite aprofundar nossos comprometimentos naturalizados com as lógicas de funcionamento das infraestruturas.Beyond Price at Aurora. Reflection on politics, infrastructure and money in ordinary lifeAbstract: This article analyzes the act of paying from the anthropological perspective on infrastructure. More specifically, the argument relies on its conceptual tools that point out the ordinary, banal and invisible dimension in which infrastructures are revealed to people in their daily interactions. This reflexive exercise is enriched by an empirical case that this bureaucratic consumption itinerary, paying for something, is organized in a different way: a restaurant in which the meal does not have a fixed, pre-set or even suggested price. The Aurora proposes the “sem preço” (without price) as a practice of “co-responsibility and mutual support” based on the understanding that money has different values in our society for each person. The contrasting effect this experience engages allows us to deepen the understanding about our naturalized commitments to the logic of the functioning of infrastructures through the constant exchange between materiality and ideology in which we are always agents and subjects.Keywords: Infrastructure. Daily Life. Money, Consumption. Political Action.
Aprendizado na experimentação animal – Aquisição de habilidades perceptivas, gestuais e afetivas
Authors: Souza Iara Maria de Almeida 
Published: July 2021

Na biomedicina roedores são usados em larga escala na produção de conhecimento. A incorporação dessas criaturasà pesquisa, envolveu um radical processo de padronização genética delas, bem como dos protocolos e técnicas voltadas para seu manejo. A ênfase na padronização e normatização não deve, contudo, ofuscar o quanto de trabalho manual e artesanal é exigido nessa atividade. Para abordar tal aspecto da prática científica, este artigo explora o processo de aprendizado da manipulação de roedores, a partir de relatos feitos por pesquisadores que atuam em uma instituição pública de pesquisa biomédica, e mostra como a capacidade de agir com destreza neste contexto requer um refinamento das habilidades perceptivas, gestuais e afetivas, que levam em consideração a força e vitalidade dos animais.
Humanos e caranguejos nos manguezais do Delta do Parnaíba: histórias da paisagem
Authors: Pereira Lucas Coelho , Silveira Pedro Castelo Branco 
Published: July 2021

A foz do Rio Parnaíba, situada no nordeste brasileiro entre os estado do Piauí e do Maranhão, origina o único Delta das Américas em mar aberto. Esta região apresenta uma rica sociobiodiversidade e exuberantes florestas de manguezais sujeitas a forças de simplificação e contaminação características do antropoceno. O presente artigo narra transformações ocorridas no Delta trazendo a paisagem como protagonista da narrativa a partir das malhas de relações entre caranguejos, manguezais e catadores de caranguejo (caranguejeiros). Por meio de uma abordagem etnográfica que considera as relações entre humanos e outras formas de vida, o artigo evidencia a constituição de paisagens multiespécie frente a processos históricos, e também narrativos, que insistem em eclipsar as diversidades biológicas e culturais. Como contraponto, o artigo enfatiza a dinâmica viva e múltipla da constituição das paisagens do Delta.Palavras chave: Manguezais. Caranguejo-uçá. Ucides cordatus. Delta do Parnaíba.
