Authors: Parekh Arpitaben Jashbhai , Prakasam Anita
Published: June 2024

The rising prevalence of chronic kidney disease poses a future challenge for healthcare and the economy. For patients diagnosed with kidney failure, hemodialysis is the sole recourse until a suitable renal donor is acquired, exerting a discernible impact on the overall quality of life. Yoga and meditation emerge as pivotal elements in enhancing quality of life (QoL), significantly influencing diverse aspects of well-being. The study aimed to identify the effectiveness of yoga and meditation on QoL among hemodialysis patients. An experimental research design with one group pretest – post-test on 100 participants was conducted in Muljibhai Patel Urology Hospital, Nadiad. Pre-tests were conducted on day 1, followed by a 12-week yoga and meditation program with a post-test. Data analysis utilised SPSS-20 software, employing descriptive and inferential statistics. Yoga and meditation effectively demonstrated improvement in QoL in each domain (p < 0.001.) post-intervention. These results emphasize QoL enhancement after incorporating these practices into hemodialysis care.

Authors: Saket Kumar , Kumari Kajal , Vijapur Manjunath , Kattimani Vasant
Published: June 2024

Facial degloving injuries present a complex medical challenge, where the skin and underlying tissues detach from the muscles, fascia, and bones beneath. These injuries pose significant difficulties for surgeons, particularly when complicated by wound infection or tissue necrosis. This case report details the experience of a 26-year-old male patient with a history of trauma, who suffered a facial degloving injury requiring reconstructive soft-tissue surgery. It outlines the challenges encountered during both the surgical and post-operative phases in managing a patient with a full-thickness avulsed flap extending from the lower face to the suprahyoid area of the neck.

Pemanfaatan ampas kopi sebagai material pendukung katalis TiO2 tidak hanya berpotensi untuk mengurangi limbah kopi yang belum dimanfaatkan dengan baik, tetapi juga dapat berperan dalam upaya pengolahan limbah logam berat Cr(VI) yang berbahaya. Salah satu cara pengolahan limbah logam berat Cr(VI) adalah dengan mereduksinya menjadi Cr(III) yang relatif lebih aman dan tidak toksik. Penelitian ini bertujuan untuk mengetahui karakteristik morfologi, komposisi unsur, luas permukaan spesifik, dan porositas dari material komposit TiO2-Ampas Kopi (TiO2-AK). Material TiO2-AK disintesis menggunakan metode hidrotermal dengan memvariasikan komposisi massa antara TiO2 dengan AK (1:9, 2:8, 3:7, dan 4:6). Material hasil sintesis dikarakterisasi menggunakan SEM-EDS dan adsorpsi-desorpsi nitrogen. Selain itu, dikaji juga aktivitas fotokatalitik material hasil sintesis dalam mereduksi Cr(VI). Hasil penelitian menunjukkan bahwa TiO2 berhasil menempel pada permukaan ampas kopi. Material komposit TiO2-AK yang disintesis memiliki struktur mesoporous dengan luas permukaan spesifik berkisar antara 23,354 m2/g hingga 30,281 m2/g. Penggunaan adsorben ampas kopi sebagai material pendukung TiO2 membentuk sinergi yang baik antara mekanisme adsorpsi dan fotokatalitik sehingga dapat mereduksi Cr(VI) dengan lebih cepat. Aktivitas fotokatalitik paling tinggi ditunjukkan oleh material TiO2-AK dengan variasi massa 2:8 yang mampu mereduksi Cr(VI) hingga 61,8% dalam waktu 6 jam iradiasi sinar UV.
On some current aspects and new approaches to scientific understanding of the national characteristics of Russian statehood formation and evolution
Authors: Omelchenko N. A. , Rastimeshina T. V. , Sinchuk Yu. V.
Published: June 2024

The object of the study is the process of Russian statehood formation and historical transformation.

   The subject of the study is the analysis of existing in the Russian scientific and public thought (pre-revolutionary and modern) different approaches to the interpretation of national features of Russian statehood foundations origin and evolution.

   The authors emphasize a number of fundamental problems of Russian statehood development, which today require creative comprehension by scientific community. The article substantiates the position on the enduring significance of domestic researchers’ and thinkers’ conclusions about the uniqueness of the process of Russian statehood foundations origin in the Old Russian state, which was fundamentally different from similar processes in Western states, the Tsardom of Muscovy political system specificity, which consisted in the cathedral structure of the state and received ideological justification in the “autocratic sobornost” doctrine. Special attention has been paid to the conclusions related to assessing significance of the long coexistence in the Russian state of two parallel beginnings such as the monarchical vertical of power and the rich veche tradition, which compensated for the relative weakness of the monarchy in technical and political sense. For the first time the issue of what place in Russian statehood transformation was occupied by the Time of Troubles of the early 17th century has been investigated in detail. Attention has been drawn to the conclusions of pre-revolutionary scientists and thinkers about the determining role of the Time of Troubles, which it played in the new attitudes’ formation to the state and state power in Russian society, including in the context of modern interpretations. The determining role of zemstvo bodies in the years of the Time of Troubles in the collapsing state preservation and revival has been pointed out. The conclusion has been made about the similarity of the Russian system of power with the Byzantine model, traditionally characterized by a combination of a rigid monarchical vertical and horizontal of developed self-government. The role of the state idea uniting society in preserving stability and sustainability of any state has been emphasized.
A Tree-Transformer based VAE with fragment tokenization for large chemical models
Authors: Inukai Tensei , Yamato Aoi , Akiyama Manato , Sakakibara Yasubumi
Published: June 2024

Chemical language model (CLM), a molecular generation model, leverages large language models by utilizing SMILES, a string representation of compounds. Chemical variational auto-encoder (VAE), which explicitly constructs a latent space, demonstrates their strength in molecular optimization and generation on a continuous space. We propose the Fragment Tree-Transformer based VAE (FRATTVAE), which treats molecules as tree structures with fragments as nodes. This method allows for fragment tokens, unmanageable with SMILES, and effectively handles large molecules, including salts and solvents. Utilizing tree positional encoding and Extended Connectivity Fingerprints (ECFP) for fragment token embedding, and applying the Transformer architecture, FRATTVAE achieves superior molecule generation accuracy and computational speed. Distribution learning across various benchmark datasets, from small molecules to natural compounds, showed that FRATTVAE consistently achieved high accuracy in all metrics while balancing reconstruction accuracy and generation quality. In molecular optimization tasks, FRATTVAE generated high-quality, stable molecules with desired properties, avoiding structural alerts.

Sodium superionic conductors (NASICON) are pivotal for the functionality and safety of solid-state sodium batteries. Their mechanical properties and ionic conductivity are key performance metrics, yet their correlation remains inadequately understood. Addressing this gap is vital for concurrent enhancements in both properties. This study summarizes recent literature on the sintered polycrystalline NASICON solid electrolyte Na1+xZr2SixP3-xO12 (NZSP, 0≤x≤3), focusing on its mechanical properties and ionic conductivity, and identifies a positive correlation between these properties at ambient temperatures. Microstructural analysis reveals that a range of factors, including relative density, grain size, secondary phases, and crystal structures, significantly influence the properties of NZSP. Notably, an increase in relative density uniquely contributes to simultaneous enhancements in both hardness and ionic conductivity. Consequently, future research should prioritize enhancing the relative density of NZSP, potentially by employing advanced sintering techniques such as spark plasma sintering (SPS) and microwave-assisted sintering. The correlation between mechanical properties and ionic conductivity observed in NZSP is also evident in other oxide solid electrolytes, such as garnet Li7La3Zr2O12 (LLZO). This investigation not only suggests a potential linkage between these crucial properties but also guides subsequent strategies for refining polycrystalline oxide solid electrolytes for advanced battery technologies.

Published: June 2024

The reverse water-gas shift reaction (RWGS) is a key technology of the chemical industry, central to the emerging circular carbon economy. Pt-based catalysts have previously been shown to effectively promote the RWGS, especially when modified by promoter elements. However, their active state is still poorly understood. Here, we show that the intimate incorporation of an iron promoter into metal-oxide supported Pt-based nanoparticles can increase their activity and selectivity for the low temperature reverse water-gas shift (LT-RWGS) substantially and drastically outperform unpromoted Pt-based materials. Specifically, the study explores the promotional effect of iron in Pt-Fe bimetallic systems supported on silica (PtxFey@SiO2) prepared by surface organometallic chemistry (SOMC). The most active catalyst (Pt1Fe1@SiO2) shows high selectivity (>99% CO) towards CO at a formation rate of 0.192 molCO h-1 gcat-1, which is significantly higher than that of monometallic Pt@SiO2 (96% sel. and 0.022 molCO h-1 gcat-1). In-situ diffuse reflectance FT-IR spectroscopy (DRIFTS) and X-ray absorption spectroscopy (XAS) indicate a dy-namic process at the catalyst surface under reaction conditions, revealing distinct reaction pathways for the monometallic Pt@SiO2 and bime-tallic PtxFey@SiO2 systems.

CARACTERÍSTICAS AGRONÔMICAS DE CROTALÁRIA OCHROLEUCA
Authors: Neto Antonio Pereira de Queiroz , Santos Pedro Henrique Neves dos , Carvalho Luzineide Fernandes de , D'Albuquerque Cristiane Lopes Carneiro , Silva Genival Celso Pereira da , Silva Jonas Pereira Sousa
Published: June 2024

A adoção da prática de adubação verde, realizada com espécies da família Fabaceae, pode significar uma estratégia importante na busca da sustentabilidade dos agroecossistemas, haja vista os benefícios proporcionados ao solo como melhoria das características físicas tais como: agregação e incremento do carbono orgânico, aporte de fitomassa e nutrientes para as áreas cultivadas, manutenção da umidade do solo, proteção contra os principais agentes causadores da degradação dos solos e controle das plantas espontâneas (TEODORO et al., 2011).
   As crotalárias, desde muito tempo utilizadas como adubos verdes, passaram a ter papel de destaque no sistema, visto que, além de proporcionarem boa produção de biomassa, melhor eficiência na utilização de fertilizantes nitrogenados devido à simbiose com bactérias fixadoras do N2 atmosférico, há também a melhoria da qualidade do solo, relacionado ao aumento do teor de matéria orgânica e maior disponibilidade de nutrientes (SILVA et al., 2017). Outros benefícios ligados a utilização de crotalárias são a alelopatia sobre plantas daninhas e o efeito antagônico a espécies de fitonematóides do solo, por meio de substâncias como a monocrotalina, consistindo em excelente alternativa para manejo destas pragas (WANG et al., 2002).
   A C. ochroleuca é planta anual, de crescimento arbustivo ereto, que pode atingir 1,5 a 2,0 m de altura, desenvolve-se em solos quimicamente pobres e com baixos teores de matéria orgânica. Apresenta potencial produtivo
de 7 a 10 t ha-¹ de matéria seca, podendo atingir valores de até 17 t ha-¹ (AMABILE et al., 2000).
HORTAS URBANAS E PERIURBANAS: PRODUTOS ALTERNATIVOS UTILIZADOS NO CONTROLE DE PRAGAS EM TERESINA-PI
Authors: Santos Vanusa Suelma Viana dos , Soares Carlota Joaquina de Sousa Rosal
Published: June 2024

As hortas urbanas e periurbanas ganharam importância político social como alternativa à redução da pobreza e melhoria da qualidade alimentar das famílias brasileiras desde o século passado (CASTELO BRANCO e ALCÂNTARA, 2011).  Elas são instaladas em espaços públicos dentro dos limites das cidades e próximo das mesmas, permitindo que os moradores trabalhem em coletividade, produzindo hortaliças de ciclo curto e de baixo investimento para consumo e comercialização (MICHEREFFE FILHO et al., 2009).
As hortaliças durante o cultivo são atacadas por inúmeras pragas, que são controladas com produtos químicos, porém seu uso inadequado tem provocado diversos problemas como resistência de insetos aos princípios ativos, presença de resíduos tóxicos nos alimentos, contaminação do meio ambiente e aumento nos custos de produção (PIMENTEL et al., 2010), além de levarem à mortalidade diversos inimigos naturais de pragas ( WATANABE e MELO, 2006).
Muitos produtores estão mais conscientes da importância do consumo de alimentos saudáveis para melhor qualidade de vida (MAFRA et al., 2007), por isso,  no controle de pragas,  vêm utilizando os produtos alternativos (SOUSA et al., 2012), que podem ser de preparação caseira ou formulados, elaborados a partir de componentes não prejudiciais à saúde humana e ao meio ambiente, como extratos de plantas, que apresentam baixa toxicidade ao homem e à natureza, custo reduzido, fácil disponibilidade, não favorece a ocorrência de formas de resistência  das pragas ao material vegetal  e apresentam eficiência no controle das mesmas (SUJII et al., 2010).
Tendo em vista os danos causados pelos inseticidas sintéticos, a ação das pragas sobre as hortaliças cultivadas e a importância destas para a alimentação humana, o objetivo deste trabalho foi identificar os produtos alternativos utilizados no controle de pragas em 10 hortas urbanas e periurbanas inseridas no processo de transição de produção convencional para orgânica em Teresina- PI.
PRODUÇÃO DE SEMENTES DE MILHO CRIOULO EM CONSÓRCIO COM ADUBOS VERDES

O milho (Zea mays L.) é provavelmente uma das espécies cultivadas com maior diversidade genética (PATERNIANI et al., 2000). Existe variabilidade genética tanto para caracteres relacionados à adaptação ambiental, quanto para aqueles que não têm influência na vantagem adaptativa (TEIXEIRA et al., 2002).
   Populações crioulas, também conhecidas como locais ou landraces, são materiais importantes para o melhoramento pelo elevado potencial de adaptação que apresentam para condições ambientais específicas (PATERNIANI et al., 2000).
   Em condições na qual é empregada baixa tecnologia de cultivo, as variedades crioulas podem apresentar rendimento semelhante ou superior às variedades comerciais. Existem também outras vantagens no uso de variedades locais, como resistência a pragas, doenças e desequilíbrios climáticos. As sementes podem ser armazenadas para safras seguintes, diminuindo assim, o custo investido na produção. Segundo Cecarelli et al. (1994), o ganho ambiental também é superior, uma vez que o uso de variedades crioulas, adaptadas localmente, mantém a diversidade genética das espécies, podendo servir de fonte para o melhoramento.
   A utilização da adubação verde, por sua vez, é uma prática promissora para manutenção da fertilidade do solo (ALCÂNTARA et al., 2000). Outros motivos citados por outros autores é a presença de um sistema radicular geralmente profundo e bem ramificado, proporcionando maior capacidade de extrair nutrientes de camadas mais profundas do solo.  Além do papel de conservação e fertilização dos solos, produzem pólen e néctar, atraindo e abrigando inimigos naturais, com impactos positivos na proteção contra pragas e doenças (ALVES et al., 2004).
   Neste contexto, torna-se interessante o uso da consorciação, pois além da otimização da área de plantio, a cultura principal pode ser beneficiada pelo nitrogênio fixado pela leguminosa, seja pela excreção direta de compostos nitrogenados e pela decomposição dos nódulos e raízes, ou mais intensamente pelo corte da parte aérea da leguminosa que irá se decompor e liberar nutrientes durante o desenvolvimento da cultura principal (CASTRO et al., 2004).
   O sucesso técnico provindo do consórcio entre milho e adubos verdes deve seguir certos critérios, como a densidade correta e época de corte dos adubos verdes. Deve-se evitar a competição entre eles por meio de um manejo correto, melhorando assim a produtividade.
   Desse modo, no presente trabalho foram avaliadas as características agronômicas e o rendimento de sementes de milho crioulo em consórcio com Crotalária juncea e cunhã.
DESENHANDO O PROJETO FEIRA DE BASE AGROECOLÓGICA-CULTURAL DA UFPI: PROPÓSITOS, ESTRATÉGIAS E PRINCÍPIOS POLÍTICO-EPISTEMOLÓGICOS.
Authors: Silva Valéria
Published: June 2024

A Feira de Base Agroecológica-Cultural da UFPI é um projeto de extensão universitária, vinculado à Universidade Federal do Piauí. Desde sua concepção primeira, já na escritura do texto do projeto, a Feira UFPI nasceu da junção de algumas inquietações, convicções e desejos pessoais; necessidades locais e parcerias com outras instituições e pessoas preocupadas em gerar uma política de produção de alimentos limpos para Teresina, visando também a constituição de um mínimo de segurança e soberania alimentar para a capital. Após mais de 1,5 anos de funcionamento regular, a Feira confirma o acerto do seu desenho político que aposta no pensamento complexo, na multidisciplinaridade, no estabelecimento de relações rurais-urbanas, acadêmico-populares, de gênero, multirraciais e transgeracionais, embaladas pela troca de conhecimentos e pela identidade cultural piauiense, expressa na arte e artesanato presentes naquele espaço. O projeto também tem mostrado vigor no que se refere a gerar possibilidades de maior acesso econômico-político-cultural ao segmento feminino rural de faixa etária média e de escolaridade em nível fundamental. Assim, alcança um segmento populacional excluído da possibilidade de emprego dignificante, bem como de grande parte das políticas públicas disponíveis na agenda do Estado. Com este desenho, a Feira de Base Agroecológica-Cultural da UFPI aparece como um pulsante espaço de atividade acadêmica de ensino, pesquisa e extensão, bem como um espaço de cultivo de esperança para as gerações rurais mais jovens quanto à possibilidade material e simbólica de reencontrarem no meio rural o seu espaço de reprodução social e de bem-viver.

A produção cinematográfica brasileira entre 1995 e 2017: uma análise empírica
Authors: DA SILVA SOUZA RICARDO
Published: June 2024

A produção cinematográfica nacional é o setor da indústria audiovisual brasileira com maior geração de empregos e o que mais cresce dentro do setor, segundo a Agência Nacional de Cinema, a ANCINE. Entretanto, ainda não se tornou economicamente independente, uma vez foi necessário a criação de uma agência reguladora para fomentar e desenvolver sua indústria, que é ANCINE, criada em 2001. Além disso, sua produção é regionalmente concentrada no Rio de Janeiro e em São Paulo, com mais de 90% das produções. Diante desse contexto, a questão a ser respondida é como os fatores emprego, incentivos fiscais e regionalização participam efetivamente na produção. Assim, o presente trabalho tem como objetivo principal analisar a produção cinematográfica brasileira entre 1995 e 2017 em função do número de trabalhadores, da concentração regional, pelo marco gestacional da ANCINE e pelos incentivos fiscais concedidos pela agência a produções cinematográficas, por meio de uma função de produção do tipo Cobb-Douglas com base nos dados fornecidos pela documentação digital do órgão. Os resultados mostram que o fator trabalho contribui de forma intensiva e que a regionalização da produção contribui de forma extensiva no que tange a produção e aos incentivos fiscais no período analisado.
Economia do Crime empírica: uma revisão bibliográfica da literatura brasileira
Authors: Souza André Luis de , Montagner Oto Murer Küll
Published: June 2024

Com o aumento nas estatísticas criminais no território nacional, o crime vem sendo considerado um problema na vida dos brasileiros. De acordo o Sistema de Informações sobre Mortalidade do Ministério da Saúde, em 2017 houve 65.602 homicídios no Brasil (IPEA, 2019). Com o espaço que o tema está conquistando na área econômica, pesquisadores buscam analisar variáveis que contribuem para a diminuição da taxa de criminalidade e também por variáveis que explicam a influência que o indivíduo recebe ao entrar no mundo do crime. Neste estudo tem-se como objetivo uma revisão bibliográfica focada em trabalhos empíricos que abordam a realidade brasileira e, assim, contribuem para definições de políticas públicas. Tem-se como metodologia o levantamento de livros, dissertações, artigos científicos publicados em revistas, lidos e fichados a respeito do tema, levando em consideração sua pouca exploração no Brasil. Conclui-se que os principais fatores que influenciam a prática do crime são taxa de desemprego, renda, Índice de Gini e escolaridade, com que o indivíduo se comporta de forma racional ao decidir praticar o crime. Políticas públicas tendem a contribuir para a redução da criminalidade no longo prazo.

Unreliable Narration and (Dis-)Orientation in the Postmodern Neo-Gothic Novel: Reflections on Patrick McGrath's The Grotesque (1989)
Authors: Antor Heinz
Published: June 2024

This article analyses the forms and functions of unreliable narration in a postmodern neogothic novel and thus tries to view the phenomenon of the unreliable narrator not merely from the point of view of the narratologist intending to devise a watertight descriptive definition of the technique and to place it consistently within-a conceptual framework. Rather, narratology and cultural studies are to be brought together here in an attempt at determining the cultural functions of a special form of narrative in a historical situation often described as plural, fragmented and devoid ofa centre, i.e. one creating problems of orientation. Unreliable narration thus turns out to be a useful tool in the artistic process of coping with the postmodern condition.
The 200 Genres of the Short Story
Authors: Bonheim Helmut
Published: June 2024

This paper aims at questioning, among other things, Charles E. May’s well-known “unified theory of the short story”. As Bonheim sees it, May’s theory would deserve to have added to it a unified theory of short story sub-genres, for the concept of “unified theory” may suggest that varieties of story invite varieties of theory, and indeed, differences between types of story can be as revealing as their similarities. Detailed criticism presupposes the discovery of a great variety of subgenres, together with a great variety of search-engines that might allow the critic to unearth relevant differentiations. An all-embracing theory of sub-genres will have, in addition to an explanatory power, an exploratoty power as well, and will make it possible for the critic, not only to assign a story to a sub-category or subgenre, but also to a category such as analytic vs. synthetic, thus taking into consideration technique as well as content. On the assumption that the genres have in fact emerged by chance rather than through scholarly analysis, students taking part in a University of Cologne seminar were asked to write down half a dozen short story types that they had not seen labelled. The feedback proved to be quite overwhelming, for the resulting master list included well over 200 entries, which would be eventually reduced to the round number of 200. These short story types would in turn be arranged in alphabetical order and carefully analysed and considered in order to reach some final and revealing hypotheses, which proved to be much more revealing than the original list itself.
Palindromes and Palimpsests: Strategies of Deliberate Self-contradiction in Postmodern British Fiction
Authors: Gutleben Christian
Published: June 2024

This paper sets out to argue that contemporary British fiction, by using palinodes, palindromes and palimpsests both on the micro- and macro-structural levels, favours a logic of association of contraries which ipso facto deconstructs any monologic reflexion and conception of the world. To combine and superimpose contrary ideas means to eschew the monolithic. It also expresses the composite, heterogeneous, and yes eclectic, nature of postmodernism and its fundamental incredulity towards any singular ideology and aesthetic tradition. Ultimately, if contemporary fiction flaunts its contradictory syncretism, it is to claim the right to simultaneously and oxymoronically defend opposed tendencies, beliefs and influences.
Linking the Syntactic and Semantic Representation of Complex Structures within the Old English Domain of Speech
Authors: Marta Mª González Orta
Published: June 2024

In order to reflect the interaction between the semantic and syntactic behaviour of predicates, the notion of lexical template has been devised as a way of including syntactic and semantic information within the same lexical representation, reflecting generalisations across lexical classes and reducing the information to be included in the lexical entries. Lexical templates are composed of the logical structures developed by Van Valin LaPolla (1997), complemented by a semantic decomposition in terms of ontological constants or internal variables and semantic primitives corresponding to the different lexical domains. As will be shown, the syntactic behaviour of a lexeme can be determined by linking the internal variables and external argument positions of a template. Within the Old English domain of speech external variables can be syntactically realised by complex structures whose semantic description will also be included in the templates.
Sentimental Comedy in Martin Amis's "State of England" and "The Coincidence of the Arts"
Authors: Verrier Luc
Published: June 2024

This article examines the analogies that "State of England" and "The Coincidence of the Arts" -two short stories extracted from Martin Amis's Heavy Water and Other Stories (1998)- bear to the conventions of sentimental comedy in order to shed light on Amis's aesthetic and ethical choices. Relying on tools such as "flyting", these stories comically rework the "pity for the poor" typical of sentimental works while borrowing from the genre of "condition of England" fiction. Yet, this comic veneer cannot conceal the apocalyptic instances of child abuse and domestic violence, topoi of sentimental works. Impending doom is nevertheless undermined by ironic patterns of reconciliation which tally with the cosmic optimism ultimately promoted by sentimental works. Since these denouements are attained via rhetorical negativity, Amis's texts are also indebted to sentimental rhetoric, a heritage that betrays a resurgence of sentimentality in the work of an author wrongfully stereotyped as an effete prophet of doom.
A Critical Review of the Terminology and Taxonomies Used in the Literature on Lexical Errors
Authors: María Pilar Agustín Llach
Published: June 2024

This paper is a critical review of the terminology and the different taxonomies in the field of lexical errors. We intend to bring some order to the terminological and classificatory chaos in the field of lexical errors by analyzing, comparing, and systematizing the different terms and classifications. We will begin with a discussion of the role of vocabulary in communication, as an academic predictor, and of the severity of lexical errors as communication distractors. Then, we turn to the inconsistencies in terminology and typology of lexical errors in the literature on vocabulary acquisition and lexical errors. These inconsistencies in terminology and taxonomies are due to the lack of a common definition for the term “lexical error”. And furthermore, they are a cause of disorder and chaos in the field of vocabulary acquisition research and they have important academic and pedagogic consequences.
Aspects of Indian Modernity: A Personal Perspective
Authors: Ramanan Mohan
Published: June 2024

The paper attempts to delineate the contours of Indian modernity by showing that it is primarily colonial modernity which is a factor in the modern Indian nation taking shape. India is distinguised from Bharat which is the old name for the geographical space which is India. Bharat is traditional and India is modern. The paper shows that these categories need not be irreconcilable opposites, that the Indian way has been to effect a dynamic partnership of the past and the present, tradition and modernity, that if India does not do so now her future is at stake. The paper examines the growth of modernity in India through the nineteenth century and argues that to a large extent even this modernity and the stirrings of nationhood are informed by a spiritual attitude to life. The paper in short argues for a usable past which will preserve the best from tradition, select from it that which is useful and reject the dross so as to forge a future which is intimately linked with the past. Evolution, rather than revolution is the paper’s burden. That is the Indian way.

Authors: Pérez Silvia
Published: June 2024

This article seeks to examine the significance of geographical setting in Samuel Selvon’s The Lonely Londoners (2006 [1956]) and Dionne Brand’s What We All Long For (2005) in order to understand the undeniable reciprocal relationship that exists between the city and its subjects. Hence, I will analyse the role played by London and Toronto in the construction and development of their inhabitants’ identities, as well as the power that city dwellers have in (re)shaping urban spaces. The article aims to examine the dynamic and fluid character of the city and intends to identify the effects that migrant communities have on rewriting and remapping urban spaces when exercising their agency.
Stress Shift in Noun-Verb Conversion Pairs: The Case of ImportN-ImportV Pairs

Conversion is a word-formation process characterised, among other aspects, by the formal identity between the original word and the resulting one (bottle à to bottle). However, there are a few cases of conversion-related words which challenge this formal identity characteristic of conversion. One of these cases is that of noun-verb conversion pairs such as importN-importV, in which a type of phonological base allomorphy occurs: stress shift. In such cases, stress shift consists in nouns tending to be stressed on the first syllable (importN /ˈɪmpɔːt/) while verbs are usually stressed on the last one (importV /ɪmˈpɔːt/). This study aims to determine which are the most frequently occurring noun-verb conversion pairs displaying stress shift and why this type of allomorphy occurs. To answer these questions, a corpus of 157 noun-verb conversion pairs was compiled from frequency lists of nouns and verbs. Out of these pairs, 25 presented stress shift. Additionally, information about the etymology and the year of introduction into English of the 25 pairs with stress shift was gathered. It was found that all the noun-verb conversion pairs with stress shift are of Romance origin. Furthermore, the results suggest that the stress shift in noun-verb conversion pairs might be due to their adaptation to the Germanic stress system after being introduced into English from either Latin or French.

W Agendzie na rzecz Zrównoważonego Rozwoju przyjęto, że m.in. zwiększony zostanie udział odnawialnych źródeł energii w globalnym miksie energetycznym oraz wskaźnik wzrostu globalnej efektywności zużycia energii. Ponadto, dążyć się będzie do zintensyfikowana międzynarodowej współpracy ułatwiającej dostęp do badań nad czystą energią i technologią w obszarze energii odnawialnej, efektywnością energetyczną oraz zaawansowanymi i czystszymi technologiami paliw kopalnych. Wobec powyższego przyszłość energetyczna wymaga będzie wielu działań adaptacyjnych. Celem artykułu jest przedstawienie wykorzystania energii przez sektor transportu w Polsce i krajach Europy Środkowo-Wschodniej, ze szczególnym uwzględnieniem wykorzystania odnawialnych źródeł energii.Metoda. W pracy posłużono się danymi Eurostatu. Do pogrupowania krajów według zużycia odnawialnych źródeł energii i biopaliw wykorzystano analizę skupień metodą Warda. Do porządkowania nieliniowego krajów w postaci dendrogramu wykorzystano siedemnaście zmiennych określających poziom zużycia końcowego odnawialnych źródeł energii i biopaliw. Ponadto, wykorzystano metodę standaryzacji w wyniku której przekształcone wartości mają rozkład o średniej 0 i odchyleniu standardowym 1.Wyniki. Transport w państwach Europy Środkowo-Wschodniej zużywa od 25% do 40% ogólnego zużycia energii, z czego 90% pochłania transport drogowy. Odnawialne źródła energii w największym stopniu są wykorzystywane w transporcie rumuńskim i estońskim. Transport państw Europy Środkowo-Wschodniej w niewielkim stopniu wykorzystuje żródła odnawialne do zaspokajania potrzeb energetycznych.
Ahmet Midhat Efendi’nin Romanlarında İntihar
Authors: Demir Özlem Nur
Published: June 2024

Tanzimat dönemi; siyasi, sosyal ve kültürel anlamda birçok yenilik ve değişimin baş gösterdiği bir dönemdir. Toplum, Tanzimatla gelen bu yenilik ve değişimlere uyum sağlama konusunda bir çatışma içerisindedir. Doğu-Batı kültürü karmaşası halini alan bu çatışmalar edebi eserlerde sıkça yer edinmiştir. Roman, hikâye, tiyatro ve gazete gibi edebi türlerin ilk ürünleriyle beraber dönemin aynası niteliğinde olan birçok eser üretilmiştir. Bu ilk örneklerin işlenişinde biçim ve içerik konusunda görülen sürekli devingenlik hali dönemin şartlarını, edebi, sosyal ve kültürel ortamını tespit etme konusunda bilhassa modern Türk edebiyatının gelişim safhalarını tespit etmekte son derece önemlidir. Tanzimat’ın getirdiği yeniliklerle beraber dönemin sanatçıları eserlerine bu toplumsal ortamı yansıtmış, bununla beraber edebi eserlerde daha önce işlenmemiş veya üzerinde durulmamış unsurlara yer vermeye başlamıştır. Bunlardan biri de intihar olgusudur. Dönemin sanatçılarının hemen hepsi eserlerinde intihara yer vermiştir. Ahmet Midhat Efendi de intihar olgusunu eserlerinde sık kullanan sanatçılardandır. Eserlerinde intihar kimi zaman toplumsal eleştiri ve toplumsal mesajlarını etkili kılmak için kullanırken, çoğu zaman da aşk, ayrılık, dert ve keder sonucunda kullanmıştır. Bu çalışmada önce Ahmet Midhat Efendi’nin edebi hayatı hakkında bilgi verilip sonrasında edebiyat ve intihar arasındaki ilişkiye kısaca değinilmiştir. Ardından çalışmanın konusunu belirleyen Ahmet Midhat Efendi’nin romanlarındaki intihar eden kişiler incelenmiştir. İntihar nedenleri ve şekilleri belirtilirken, romanlar hakkında kısaca bilgiler verilip olaylara hakimiyet kurulması amaçlanmıştır.

Natural gas has a great potential because of the large reserves that currently exist at a worldwide level and because it is a cleaner source of energy than petroleum, but having the disadvantage of requiring high costs for its transportation. For this reason many alternatives for the development of reserves have loomed. Among these is the conversion of natural gas into synthetic ultra-clean fuels, called GTL, or Gas-to-liquids. Through this process, Fischer-Tropsch for the production of diesel, naphta and specialized products, which are used not only to effectively utilize natural gas reserves, but also, to cover at the need of more environmentally-friendly fuels. This article will shed light on GTL technologies, presenting on a first instance an analysis of the different stages of the Fischer-Tropsch process, then the current status of this technology, afterwards the costs of investment and the necessary conditions for a project of this kind to be carried out and finally, and analysis of the applicability or projection for this technology in Colombia. Based on recent studies, it has been observed that is technology has surpassed its demonstrations stage and it is now at a maximum point of interest where companies like Sasol (the largest worldwide company in the area of synthetic carbon-based fuels), Chevron Texaco, Syntroleum, ExxonMobil, ConocoPhillips, BP, Rentech and Shell. These companies have performed successful studies for the applicability of the Fischer-Tropsch technology at a large scale, and they will begin to build a number of large plants within the next few years, principally motivated by the low costs of gas and high prices of crude oil.

The increase in severity of visbreaking relates to an increase in olefin concentration in the visbreaking pitches. To conditions of the recovery of gas oils in the vacuum distillation tower, these olefins undergo oligomerization reactions, which produce sludge/polymers. The oligomerization reactions are favored by high temperatures, increment in the times of residence, free radicals and metals that can act as catalysts. The polymers are deposited in the Glitsch meshes and they become traps for the asphalt that are carried by the vapor currents. As a consequence of this process, the free area of the meshes is decreased and the linear rates of the vapors are increased. In time, an increment is registered in the pressure drops of the meshes as well as a growing contamination of the gas oils. The experimentation demonstrated high solubility of the components that cause this contamination. As a result of the study, a methodology for online tower clearing was put into practice and the problem indicated was controlled.

Published: June 2024

Agroup of native bacteria with a sulfide oxidation capacity was isolated at the Instituto Colombiano del Petróleo (ICP). The bacteria were immobilized in an inert inorganic support of sintered glass that was used to evaluate a fixed packed column system working in batches as well as in a continuous mode. The experiments carried out in real wastewater and in refinery sour water show high sulfide removal percentages (over 90%) both in low and high sulfide concentrations. The appropriate operation pH is in the alkaline range (8.0 to 9.0) and it decreases as the reaction proceeds. The ability of the microbial consortium to take in the ammonia nitrogen required for their metabolic activity and a possible heterotrofic nitrification, and the phenol present in the stream as a carbon source for some of the formulated strains, is demonstrated. Sulfur mass balances are carried out quantifying it as sulfates, tiosulfates, sulfide, and elementary sulfur. The effect of operational changes on the sulfide removal percentage is evaluated obtaining a quick response of the system. A kinetic analysis was carried out and the corresponding constants derived from the Michaelis-Menten equation were calculated. The maximum removal velocity and the saturation constant are Vm = 6.03-1 0 kg S/m s and Ks = 2.1325-10-4 kgS/m3.
