In der Wirtschaft vernetzt kommunizieren – Hypertextstrukturen bei der Mitarbeiteranwerbung im deutsch-polnischen Kontrast
Authors: Szwed Iwona
Published: June 2023

By dissolving the linear reception of texts, the recipient becomes a co-author intervening in the textual process (cf., Hess-Lüttich 1997: 134), who creates intertextual links, according to his or her reading strategy. This is how hypertexts and text networks arecreated, which still represent a linguistically under-researched area. What seems to be interesting here is the question of the differences between the two phenomena. The new trends can be particularly observed in business communication. For this reason, the present paper focuses on business-related texts to better illustrate the new linguistic phenomenon of text networking. The analysis is based on the Internet career pages of selected Polish and German public companies. The author attempts to find an answer to the question of the linguistic status of these websites, whether they should be defined as hypertexts or as components of larger networks of texts (textual genres). Furthermore, the aim of the paper is to point out relevant cultural and industryrelateddifferences based on the analysis of the frequency and specificity of text linking in the context of employee recruitment in Polish and German professional contexts.
Gwara jako tworzywo tekstów literackich
Authors: Bogoczová Irena , Bortliczek Małgorzata
Published: June 2023

This article aims to analyse dialect stylisation of literary texts written by authors from the Czech part of Cieszyn Silesia. This analysis was grounded in linguistic (stylistic) theories of hierarchical language and text structure. The article brings definitional and terminological considerations relating to the subject of stylisation as well as the results of a study of authentic linguistic material. From the point of view of stylistic analysis, the division of local authors into members of the Polish minority and those who belong to the Czech-speaking majority is important. It turns out that the dialect in the works of Polish authors serves, among other things, as an exponent of Polishness and, in the case of Czech authors, it is a kind of advertisement for the region, hitherto rather unnoticed by Czechs from other parts of the Czech Republic.The literature under study deserves to be highlighted for its thematic originality and for its linguistic stylisation. The cultural, social or regional embedding of the plot has a unique character, resulting from the unique history of Cieszyn Silesia. This text offers a rich exemplification of the conclusions formulated by the authors whose analysis is a linguistic voice in the discussion of the specific cultural situation of the Czech part of Cieszyn Silesia.
From pre-service to in-service teachers: Elementary English teachers’ experiences and perceptions of the pre-service teacher education
Authors:   The Korea Association Of Primary English Education, Ahn Kyungja
Published: June 2023

This study aimed to explore elementary English teachers’ experiences and perceptions of English pre-service teacher education (PRESET). In addition, it investigated the impact of PRESET on the teachers’ English language teaching (ELT). It also examined the teachers’ perceptions of ELT as pre-service and novice English teachers. Fifty elementary English teachers participated in the survey. Among them, ten teachers participated in the focus group research, and their interviews, reflection journals, and lesson observations·analysis were collected and analyzed qualitatively. The results are as follows: Overall, the teachers perceived the PRESET curriculum, teaching practicum, extracurricular activities, and the preparation for the Teacher Employment Test positively in terms of their adaptability into real-life ELT. At the same time, some teachers did not find PRESET particularly useful for their current teaching, because it was not applicable to their real English classroom context. It is implied that PRESET should be improved in order to heighten the teachers’ development of English language and English instructional skills, leading to their learners’ English communicative competence. In particular, there is a need to develop the Teacher Employment Test to measure and support the teachers’ English teaching skills more effectively. Important implications regarding elementary English teacher education will be further discussed.

Introduction: In practice, the diagnosis of certain oral lesions must be made by biopsy. A biopsy constitutes an essential diagnostic tool in application to patients with oral pathology. However oral biopsy is not routinely performed in general dental practice. The present study aimed to explore the attitudes of General Dental Practitioners (GDPs) towards oral biopsy for diagnosis of oral lesions in Vadodara city, Gujarat, India. Methodology: A questionnaire was distributed to 200 general dental practitioners, consisting of several items addressing the socio-demographic and professional aspects and their attitudes towards oral biopsy procedures. Results: Our study showed that 73% of the GDPs do not perform a biopsy on their own. Out of which 32% of GDPs gave the reason of lack of skills and knowledge while 7% of GDPs lacked confidence in performing a biopsy on their own. 28% of the GDPs were not aware of the medium of specimen preservation. Conclusion: There is a need for better education and training of GDPs to perform oral biopsy procedures on their own and create awareness among them about the proper referral of the specimen to oral histopathological centers which will aid in accurate diagnosis of the lesions.

Objetivo: Demonstrar como o tratamento não-farmacológico pode auxiliar na redução dos níveis pressóricos em pacientes portadores de hipertensão arterial sistêmica (HAS), destacando seus efeitos no paciente. Revisão bibliográfica: Em relação aos aspectos não farmacológicos do tratamento da HAS, destaca-se que estudos evidenciaram benefícios substanciais aos pacientes aderentes de dietas equilibradas, exercícios físicos e demais terapêuticas alternativas, como a acupuntura. Tais intervenções apresentam custo reduzido, risco mínimo e eficácia comprovada para o controle e redução da pressão arterial, além de possibilitar a prevenção de possíveis complicações da patologia. Contudo, é importante ressaltar que em casos mais graves e avançados dessa condição, o tratamento farmacológico é indispensável, mas se associado a essas medidas terapêuticas os resultados podem ser ainda mais satisfatórios e duradouros. Além disso, outro fator relevante ao se prescrever abordagem não medicamentosa é a potencial não adesão do paciente aos novos hábitos, situação usual neste grupo. Considerações finais: O tratamento não-farmacológico pode auxiliar na redução da pressão arterial de modo relevante e contribuir para uma melhoria significativa da qualidade de vida do paciente.

Türkiye’de rekreasyon/turizm etkinlikleri kapsamında en fazla tercih dilen korunan alanlardan biri de tabiat parklarıdır. Ayrıca, flora ve fauna toplulukları için önemli yaşam alanları olan göller, estetik öneme sahip rekreasyonel açıdan popüler alanlardır. Salda Gölü Tabiat Parkı, benzersiz kumları ile hassas bir ekolojik yapıya sahip, Türkiye’nin en önemli tabiat parklarından biridir. Tabiat Parkı’nın ziyaretçi sayısı her geçen gün önemli ölçüde artmaktadır. Bu sebeple hem Salda Gölü’nün hem de Salda Gölü Tabiat Parkı’nın sürdürülebilirliğinin parkın rekreasyonel taşıma kapasitesi ile yakından ilişkili olduğu düşünülerek Salda Gölü Tabiat Parkı’nın Fiziksel Taşıma Kapasitesi (FTK), Gerçek Taşıma Kapasitesi (GTK) ve Etkin Taşıma Kapasitesi (ETK) analizleri gerçekleştirilmiştir. Mevcut ziyaretçi sayıları ile FTK karşılaştırıldığında hafta içi (1168 ziyaretçi/gün) kullanımların fiziksel kapasiteyi aşmadığı ancak hafta sonu kullanımların (2070 ziyaretçi/gün) fiziksel kapasitenin üzerinde olduğu tespit edilmiştir. Mevcut imkânlar (mevcut personel, altyapı, üstyapı ve tesisler) dâhilinde fiziksel kapasitenin ancak

%62’sinin kullanabileceği bu sebeple ETK’nın daha düşük olduğu görülmüştür. FTK’nın üzerinde kullanımların önüne geçebilmek için rezervasyon sistemlerinin ve diferansiyel ücretlendirme politikalarının geliştirilmesi önerilmiştir.

Suppression of Lignin Repolymerisation to Enhance Cellulose Bioconversion and Lignin Valorisation – A Review
Authors: Pielhop Thomas
Published: June 2023

The recent discovery that the prevention of lignin repolymerisation/condensation in lignocellulosic biomass pretreatment can both enhance the bioconversion of cellulose and the quality of the obtained lignin, has brought a lignocellulose biorefinery closer to reality. In this work, the development of this approach and the last advancements are reviewed. The review reveals the successful implementation for a wide range of lignocellulosic substrates including softwood, hardwood, and agricultural residues. As well, it is shown that the approach can enhance various pretreatment technologies, including steam, acid and organosolv processes. Recent developments involve the discovery of new and greener additives which prevent lignin repolymerisation, the implementation of cellulose saccharification at industrially realistic conditions and high-yield fermentation. In addition, first applications of the lignin obtained in these processes are reviewed, showcasing its enhanced quality for functionalisation and use in polymers, as well as for its depolymerisation to aromatic monomers. The recent progresses bring closer the prospect of a biorefinery that can valorise all fractions of lignocellulosic biomass.
Late Microaerobic Growth for Efficient Production of Human Cytochrome P450 3A4 in E. coli
Authors: Marchetti Luca , Planchestainer Matteo , Panke Sven , Held Martin
Published: June 2023

Detailed preclinical characterization of metabolites formed in vivo from candidate drug substances is mandatory prior to the initiation of clinical trials. Therefore, inexpensive and efficient methods for drug metabolite synthesis are of high importance for rapid advancement of the drug development process. A large fraction of small molecule drugs is modified by monooxygenase cytochrome P450 3A4 produced in the human liver and intestine. Therefore, this enzyme is frequently employed to catalyze metabolite synthesis in vitro, making 3A4 availability a critical requirement in early drug development. Unfortunately, the recombinant production of this enzyme in microbial hosts is notoriously difficult. Maintaining low oxygen transfer rates and the use of rich media for host cultivation are required for P450 3A4 production. However, detailed studies on the relationship between oxygen supply and P450 3A4 space-time yields are missing. We describe an improved biotechnological process for the heterologous expression of P450 3A4 together with its redox partner, cytochrome P450 reductase, in Escherichia coli. Enzyme production was most efficient under so-called “late microaerobic” growth conditions, in which the cells have just not yet made the switch to anaerobic metabolism, characterized by a limited oxygen supply leading to oxygen concentrations in the liquid phase that are far below the detection limit of standard oxygen electrodes. Furthermore, feeding the carbon source glycerol as well as controlling cellular acetate formation improved process productivity. The presented protocol resulted in the formation of functional recombinant 3A4 at concentrations up to 680 nmol L-1.

The article analyzes such concepts as the sharing economy model, gig economy model, economic uber model, human cloud platforms. The change in the perception of remote and hybrid employment forms by society in general and business in particular after the Covid-19 pandemic is considered in detail. Such primary manifestations of new approaches to the use of resources as coworking, coliving, carsharing, carpooling, timeshare are studied. In the course of the conducted research, the main drivers were discussed that international companies voice as key for accessing human cloud platforms, generally coinciding with the Russian companies’. Recommendations for working with projects in the flexible instruction mode were also highlighted, which should be taken into account by organizations that have decided to turn to the services of human cloud platforms, namely: the existing policy simplification and realization of procedures, readiness for discomfort and its minimization for employees, flexibility in the control of all types of resources, adaptation for the absence of “correct” answers. The article identified barriers to the conclusion of a contract for freelance performers and customer companies on the human cloud platform and proposed promotion channels for the Professionals 4.0 platform and similar human cloud platforms.
Gifting representations’ analysis in the digital environment of Moscow museums
Authors: Romanov V. D.
Published: June 2023

The article presents the research results of gifting online-representations of 170 museums in Moscow (federal, regional, private). Data collection and its interpretation were structured around the duality of the museum gift as a semantic unit representing the following categories: 1) appeals and requests from museums for different types of property support (new items or monetary donations); 2) gifts previously given to the museum, presented in electronic catalogues. The data collected from the materials of Moscow museums’ websites showed that appeals for assistance to museums, regardless of the type of charity, are the lot of a minority (8–15 %). In turn, 82 museums have systematized electronic catalogues, among them only 13 % clearly distinguish information about the way of items’ arrival and through a gift, including in a separate category of description. Considering a long history of philanthropists’ influence on the formation and development of museums, and evidence of existing museum support practices, the author does not argue about low intensity of donations in museum institutions, but offers to draw a conclusion about the relationship between low articulation of gift intentions and donations in the collections and functioning of the museum field in Moscow, its rules and shared norms.
The Essential Roles of Cp Ring Activation and Coordinated Solvent During Electrocatalytic H2 Production with Amine-Rich Fe Complexes

Published: June 2023

Cyclopentadienyl (Cp), a classic ancillary ligand platform, can be chemically non-innocent in electrocatalytic H-H bond formation reactions via protonation of coordinated η5-Cp ligands to form η4-CpH moieties. However, the kinetics of η5-Cp ring protonation, ligand-to-metal (or metal-to-ligand) proton transfer, and the influence of solvent during H2 production electrocatalysis remain underexplored. We report in-depth kinetic details for electrocatalytic H2 production using Fe complexes [CpFe(CO)2(NCMe)]+ with amine-rich cyclopentadienyl ligands (Cp = enCpN; en = ethylenediamine, N = NHiPr, Pyrrolidinyl), which generate H2 with a maximum turnover frequency of 266 s-1 via η4-CpH intermediates. Under reducing conditions, state-of-the-art DFT calculations reveal that coordinated solvent plays a crucial role in mediating stereo- and regioselective proton transfer to generate (endo-CpH)Fe(CO)2(NCMe), followed by rapid solvent release and ligand-to-metal proton transfer to generate CpFeH(CO)2. The isoelectronic model complex (endo-CpH)Fe(CO)3 is prepared and structurally characterized, and the replacement of CO with NCMe dramatically increases the ligand dissociation barrier from ΔG‡ ≅ 5 kcal/mol to ΔG‡ ≅ 34 kcal/mol. The on-cycle intermediate CpFeH(CO)2 was prepared and cleanly reacts to release H2 and regenerate [CpFe(CO)2(NCMe)]+, which is rate-limiting during electrocatalysis. The solvent-free complex CpFe(CO)2 was found to be catalytically inactive and reversibly dimerizes in solution to form the crystallographically characterized dimer [CpFe(CO)2]2, further supporting the important role of coordinated solvent during H2 production electrocatalysis. Collectively, these experimental and computational results underscore the emerging importance of Cp ring activation, inner-sphere solvation, and metal-ligand cooperativity to perform proton-coupled electron transfer catalysis for chemical fuel synthesis.
Ru(II) Complexes with Protic- and Anionic-Naked-NHC Ligands for Cooperative Activation of Small Molecules
Authors: Nath Shambhu , Yadav Ekta , Raghuvanshi Abhinav , Singh Amrendra K.
Published: June 2023

A set of ruthenium(II)-protic-N-heterocyclic carbene complexes, [Ru(NNCH)(PPh3)2(X)]Cl (1, X=Cl and 2, X=H) and their deprotonated forms [Ru(NNC)(PPh3)2(X)] (1ʹ, X=Cl and 2ʹ, X=H) are reported where NNC is a new unsymmetrical pincer ligand. The four complexes are interconvertible by simple acid-base chemistry. The combined theoretical and spectroscopic investigations indicate charge segregation in anionic-NHC complexes (1ʹ and 2ʹ) and can be described from a Lewis pair perspective. The chemical reactivity of deprotonated complex 1ʹ shows cooperative small molecule activation. Complex 1ʹ activates H-H bond of hydrogen, C(sp3)-I bond of iodomethane, and C(sp)-H bond of phenylacetylene. The activation of CO2 using anionic NHC complex 1ʹ at moderate temperature and ambient pressure and subsequent conversion to formate is also described. All the new compounds have been characterized using ESI-MS, 1H, 13C, and 31P NMR spectroscopy. Molecular structures of 1, 2, and 2ʹ have also been determined with single-crystal X-ray diffraction. The cooperative small molecule activation perspective broadens the scope of potential applications of anionic-NHC complexes in small molecule activation, including the conversion of carbon dioxide to formate, a much sought after reaction in the renewable energy and sustainable development domains.
Modular solar-to-fuels electrolysis at low cell potentials enabled by glycerol electrooxidation and a bipolar membrane separator
Authors: Mehrabi Hamed , Schichtl Zebulon , Conlin Samuel , Coridan Robert
Published: June 2023

Solar fuel generation through water electrolysis or electrochemical CO2 reduction is thermodynamically limited when paired with the oxygen evolution reaction (OER). The glycerol electrooxidation reaction (GEOR) is an alternative anodic reaction with lower anodic electrochemical potential that utilizes a renewable coproduct produced during biodiesel synthesis. We show that GEOR on a Au-Pt-Bi ternary metal electrocatalyst in a model alkaline crude glycerol solution can provide significant cell potential reductions even when paired to reduction reactions in seawater and acidic catholytes via a bipolar membrane (BPM). We showed that the GEOR-BPM combination lowers the total cell potential by 1 V at -10.0 mA cm-2 compared to an anode performing OER in hydrogen evolution and CO2 reduction reactions for extended periods of up to 80 hours, with minimal glycerol crossover. These results motivate new, high-performance cell designs for photoelectrochemical solar fuels integrated systems.
Tuning Imine and Boronic Acid Reactivity with Neighboring Group Effects: Iminoboronates and Diazaborines in Bioconjugation Chemistry, Sensor Development, and Stimuli-Responsive Materials
Authors: Haggett Jack , Domaille Dylan Wythe
Published: June 2023

Dynamic covalent chemistry (DCC) are reversible reactions at chemical equilibrium. Owing to their reversible dynamics, these reactions represent an expansive toolbox for the development bioconjugation techniques and stimuli responsive materials. Several DCC reactions fit the criteria necessary for bioconjugation chemistry, including the condensation of α-amines with carbonyls to form hydrazones or oximes and the condensation of boronic acids with vicinal diols to form boronate esters. Separately, the chemical features of these reactions offer their own advantages in the development of bioconjugation and stimuli-responsive materials. However, when combined, novel reactivity and applications are unlocked. Iminoboronates are an emerging class of compounds that include an imine in the ortho position relative to an aryl boronic acid, combining the features of arylboronic acid reactivity with that of imine chemistry. In iminoboronates, the reactivity of the arylboronic acid and imine functionalities are dependent on each other, leading to unique behavior of the imine/boronic acid ensemble. Here, we review the applications of iminoboronates in bioconjugation chemistry, including their utilization in the bioconjugation of peptides, the labeling of whole cells, the development of chemical probes, and as key linkages in stimuli-responsive biomaterials.

Authors: Rohit Kushwaha , Harendra Chauhan , Chandan  , Ashutosh Kumar Singh
Published: June 2023

The design of a compact monopole dual-band antenna suitable for dual-band applications is proposed in this research. The antenna consists of eight rectangular patches, each measuring 40 × 30 × 1.6 mm³. It is designed to operate in two frequency bands: 2.18–2.63 GHz and 7.10–7.91 GHz, with resonance frequencies at 2.4 GHz and 7.5 GHz, ensuring a return loss (S11) of less than 10 dB. The results demonstrate that the proposed antenna achieves a bandwidth of 450 MHz (2.18–2.63 GHz) and 810 MHz (7.10–7.91 GHz). This bandwidth coverage allows for the inclusion of the 2.4 GHz range required for WiMAX as well as the 7.5 GHz range suitable for short-range radar and wireless data transmission applications.

Published: June 2023

Alzheimer's Disease (AD) is the most common form of dementia among middle-aged and older adults (Gale, Acar & Daffner, 2018). In addition to the impact of dementia on individuals and the people close to them, the worldwide cost of dementia was estimated to be US$818 billion in 2015 and is projected to triple by 2050 (Livingston et al., 2017). Currently, AD has no cure or treatment. However, the research on prevention or the delay of onset is promising. AD has modifiable and non-modifiable risk factors; by targeting the modifiable risk factors, the disease can be prevented. Modifiable factors include nutrition, and physical and social activity, amongst others (Livingston et al., 2017; Polidori, Nelles, & Pientka, 2010). This research will address the social activity factor from a design perspective by asking how we can design for social activity in a way that promotes brain health. In particular, social support, a social function which was found to have positive effects on cognitive health, will be explored (Zuelsdorff et al., 2019). This research has utilised the actor-network theory as a theoretical framework in combination with human-centred design methodology. Methods such as literature reviews, interviews, cultural probes, and rapid prototyping helped gather data and conduct design iterations. Based on the iterative design process and the data gathered through it, a new design is proposed. The design aims to increase social support in combination with other brain health activities both in online and offline settings. Based on this research, design guidelines that could be used by designers, online and offline communities, and organisations are proposed, alongside directions for future research.
USOS ANTAGÔNICOS NO LITORAL: DO MODO DE VIDA TRADICIONAL NA PRAIA DE MANGUE SECO (MA) AO TURISMO NA PRAIA DA LAGOINHA (CE)
Authors: Marques Matheus Andrade , Maia Filho José Almir Ramos
Published: June 2023

A presente pesquisa apresentou uma análise a respeito dos processos de uso e ocupação existentes no litoral brasileiro. Assim, usa-se como áreas de investigação as praias de Lagoinha (CE) e de Mangue Seco (MA), com o anseio de caracterizar e refletir sobre suas dinâmicas de usos, transformações e implicações para as comunidades locais. Para efetivação do referido objetivo, analisou-se aspectos como atividades econômicas desenvolvidas nas praias, configuração paisagística, desenvolvimento de práticas de cunho turístico e outros. Como resultados, constatou-se que a praia de Lagoinha se encontra em um processo de alteração paisagística em função da fixação de um mercado imobiliário que se instaurou no local em prol da existência de um potencial turístico a ser explorado na praia. Já na praia de Mangue Seco, onde predominam práticas tradicionais, como a pesca executada pela comunidade local, identificou-se maior preservação de sua composição paisagística e cultural. Por fim, constatou-se que as dinâmicas e atividades identificadas em ambas as praias, dizem respeito a distintos processos de intervenções que foram efetivados nesses ambientes.
LICENCIAMENTO AMBIENTAL E MINERAÇÃO EM MINAS GERAIS: ALINHAMENTO DE INTERESSES E CAPTURA REGULATÓRIA
Authors: Malveira Catão Camila Lopes , Carneiro Ricardo
Published: June 2023

Entendido como um instrumento regulatório fundamental para o cumprimento do dever estatal de tutela ambiental e controle da atividade econômica, o licenciamento ambiental foi instituído no Brasil por meio da Lei nº 6.938 de 1981, que estabeleceu a Política Nacional de Meio Ambiente (PNMA). De acordo com a PNMA, as atividades utilizadoras de recursos ambientais com potencial de gerar degradação ambiental, como a indústria de extração mineral, dependeriam de prévio licenciamento por órgão estadual. Em Minas Gerais, a concessão das referidas licenças compete ao Conselho Estadual de Política Ambiental (Copam), cuja estrutura é composta por Câmaras Técnicas Especializadas, dentre as quais a Câmara de Atividades Minerárias (CMI). O artigo aborda o licenciamento ambiental da atividade extrativa de minério de ferro à luz da noção de captura regulatória, que postula a existência de uma falha no processo de regulação, a qual minaria os fundamentos do interesse público ao recepcionar a influência de interesses privados revestidos de maior capacidade de pressão sobre legislador e o ente regulador. A partir de análise empírica, desenvolvida por meio de pesquisa de cunho qualitativo, centrada no estudo das atas das sessões de deliberação da CMI/Copam, sustenta-se que o licenciamento resta capturado pelo setor regulado, conforme é indicado pelos argumentos empregados pelos atores decisórios que representam o Estado, bem como pela maioria dos conselheiros que representam a sociedade civil, quando da fundamentação de seus votos. Esse resultado é referendado por auditoria pública realizada pela Controladoria Geral do Estado (CGE/MG) acerca do arranjo institucional da CMI/Copam e de suas deliberações. Como conclusão, aponta-se para a prevalência de um modelo de regulação estatal “enviesado”, caracterizado por forte alinhamento das esferas econômica e política, em detrimento do cumprimento do dever estatal, constitucionalmente instituído, de tutela ambiental.
CARACTERIZAÇÃO DO MEIO FÍSICO E DA COBERTURA DA TERRA NA BACIA HIDROGRÁFICA DO RIO POTI (CEARÁ E PIAUÍ)
Authors: Ribeiro Karoline Veloso , Albuquerque Emanuel Lindemberg Silva , Meireles Antônio Jeovah De Andrade
Published: June 2023

O levantamento de dados sobre as características físicas e de uso da terra são determinantes para o planejamento e conservação da paisagem, tendo em vista a necessidade de considerar a visão integrativa nos estudos das bacias hidrográficas. Nesse sentido, objetivou-se caracterizar as variáveis ambientais e socioeconômicas (uso e cobertura da terra) da Bacia Hidrográfica do Rio Poti (BHRP), com o intuito de contribuir com o desenvolvimento de políticas públicas que tratem do uso, manejo, recuperação, preservação e conservação dos sistemas naturais. Os dados coletados foram analisados por meio de abordagem quali-quantitativa, sendo a caracterização ambiental fundamentada na abordagem sistêmica. Foi possível definir as  unidades litoestratigráficas datadas do Paleoneoarqueano ao Cenozoico, com predomínio de rochas das Províncias Parnaíba e Borborema. Com relação às Unidades Morfológicas, ganharam destaque os relevos: Padrão em Patamares, Padrão em Formas Tabulares, Padrão em Morros, Planícies Fluviais, Padrão em Planalto/Glint, Superfície Sertaneja e Maciços Cristalinos. Em relação ao clima, constatou-se condições de transição entre o clima Semiárido, à leste, gradando,  para oeste, às condições de maior umidade do clima Tropical. Observou-se na dinâmica fluvial diferenças significativas: o regime de escoamento é de caráter temporário no alto e médio curso fluvial e caráter perene no baixo curso. Em relação aos solos, destacaram-se os: Plintossolos, Latossolos, Chernossolos, Argissolos, Neossolos, Planossolos e Luvissolos, recobertos por vegetação típica de zona de transição entre os biomas Cerrado e Caatinga. No tocante ao uso e cobertura da terra, foram estimados dois níveis para o estudo: o Natural e o Antrópico. Com o mapeamento foi possível constatar que a destruição da vegetação primária foi relacionada com o aumento de áreas agrícolas (11,7% em 1985 para 13,7% em 2021), da expansão urbana e do desmatamento (0,2% em 1985 para 0,4% em 2021 para a expansão urbana e 12,5% em 1985 para 14,6% em 2021), especialmente no Bioma Caatinga.

Introduction: Healthcare-associated Infections (HAI) have a significant impact on public health, and the use of indicators is a common practice for assessing and improving healthcare services. Aim: This study aimed to describe the utilization of blood culture results to develop indicators for hospital management and evaluate antimicrobial resistance. Outlining: This cross-sectional study was conducted at a teaching hospital. Blood cultures were performed during two periods: pre-implementation of antimicrobial sales restrictions in Brazil (05/2010-10/2010 - first period) and post-implementation (02/2011-07/2011 - second period). Computerized system reports were used to develop indicators, including infection incidence rates and antimicrobial resistance. Results: A higher infection rate (1.97/100 person-days) and a lower resistance rate (0.62/100 person-days) were observed in the second period, with the microorganism Staphylococcus sp. being more frequently identified in both periods. Implications: This study demonstrates the use of indicators to evaluate governmental actions related to HAIs, which can contribute to patient safety and healthcare management.
Inmersión en el problema del mito de Frankenstein
Authors: Dieryck Barrena Manuel
Published: June 2023

Mary Shelley desarrolla su pensamiento filosófico en su creación literaria. En Frankenstein nos enfrenta con nuestra humanidad a través de la complejidad de sus personajes, los cuales representan una crítica a la sociedad patriarcal de la autora, a las relaciones entre individuos, al desarrollo de la ciencia e, incluso, a la relación que mantenemos con la naturaleza. Se exploran en este trabajo estos temas, dando cuenta de cómo Mary Shelley, habiendo captado el carácter trágico de los mitos, configura en torno a la transgresión de Víctor Frankenstein una profunda reflexión sobre el conocimiento, la identidad y la diferencia.

Mirar la arquitectura con humor. CAU y Focho: De la ‘ligne claire’ a la viñeta hermética (1979-1982)
Authors: Tárrago Mingo Jorge , Villanueva Fernández María
Published: June 2023

Las intersecciones entre la arquitectura y el humor son numerosas. Como parte de la realidad social, la arquitectura y el arquitecto son objeto de la sátira en los mismos medios en los que la opinión pública trata cualquier otro suceso de interés. También puede encontrarse el humor en la teoría y la práctica de la arquitectura de modos diversos. Sin embargo, no es tan frecuente encontrar humor gráfico en las revistas de arquitectura de forma estable. El artículo expone y analiza el caso poco conocido de la colaboración regular del arquitecto Justo Isasi, ‘Focho’, para la revista CAU entre 1979 y 1982. Mediante material de archivo y una entrevista al autor, plantea –a la vez que se observa la evolución en los planteamientos gráficos de Focho– cómo mirar la arquitectura bajo el prisma del humor gráfico nos aleja por un momento de su lectura más ortodoxa y desde una óptica que por caricaturizada no deja de ser más precisa y lúcida sobre los debates del momento.
La ventana como símbolo del mirar del arquitecto
Authors: De Molina Santiago
Published: June 2023

La historia de la mirada de la arquitectura no transcurre por cauces accidentados salvo el que se produce en el Renacimiento. En ese instante, con la aparición de la perspectiva y con la consolidación del tropo de la ventana, la arquitectura toma conciencia del verdadero papel de la mirada. Si la visión de la perspectiva frente a la que brinda la ventana ha estado claramente privilegiada, la riqueza simbólica, física y social de esta última no es menor. El texto desgrana la historia de la ventana desde una aproximación fenomenológica y psíquica. Si la pintura se ha apropiado de la ventana para subrayar su poder delimitador, la arquitectura la reivindica como espacio intertextual desde el que pensarse. La ventana simboliza la imagen del mirar arquitectónico por cuanto enmarca, focaliza y descarta parte del mundo. Desde Ledoux a Le Corbusier la ventana permite ver a su través, a la vez que permite ver la mirada misma. La ventana condensa la mirada de la arquitectura gracias a la concentración material y psicológica que representa. En resumen, representa, por si misma, la poderosa fenomenología del mirar del arquitecto.
