Authors: Shishkin Nickolai Dmitrievich , Marysheva Marina Aleksandrovna , Ivanchuk Evgeniy Alexandrovich
Published: June 2024

A brief description of power plants using renewable energy sources is given for autonomous power supply to small oil and gas field facilities with a power of no more than 20 kW, wind power plants in their composition – 10 kW with an energy efficiency of no more than 0.35-0.45. A modernized design of a vortex wind-solar power plant based on a combined H-Darrieu-Savonius rotor has been developed. Experiments were carried out on a laboratory vortex wind-thermal power plant, simulating the operation of a vortex wind-solar power plant. Experiments have shown that the rotation frequency and power of the H-Darieu rotor in a vortex tube will be greater than for the H-Darieu rotor in a horizontal air flow. This effect is explained by the peculiarities of the aerodynamics and energy of H-Darier rotors placed in a circular flow in a vortex tube. It is shown that the power of this installation can exceed the power of other types of wind power plants by an order of magnitude and the energy efficiency reaches 0.70. An example of an energy-technological scheme for using a modernized vortex wind-solar power plant to drive well pumps for oil production is given. It is shown that in this scheme the costs of traditional energy resources for oil production can be reduced by 2 times.

Published: June 2024

O presente artigo “Responsabilidade civil por erro médico de diagnóstico”, tem como objetivo analisar dentro do ordenamento jurídico civil o dever de responsabilizar o médico por erro de diagnóstico, visto que aos olhos da justiça a relação médico-paciente passou a ser vista como relação de consumo. Para tanto, o estudo parte do método de abordagem dedutivo, através de pesquisa qualitativa, com a intenção de trabalhar características e ideias relacionadas à temática, utilizando-se da pesquisa bibliográfica, alicerce teórico sobre o tema em apresso. Ainda, o presente estudo tratará da responsabilidade subjetiva e como ela se adequa as ações de responsabilidade médica, a qual tem como exigência a prova da culpa juntamente com seus elementares, negligência imprudência e imperícia. Seus requisitos como a culpa, ação do indivíduo que dá causa ao dano, dano, prejuízo causado por ação ou omissão e nexo causal, o liame entre dano e culpa, e quando a responsabilização civil do médico referente ao erro médico, mais especificamente sobre o erro de diagnóstico, considerado o mau resultado de uma ação ou omissão. A preocupação do Poder Judiciário na buscar da resolução em ações de erro médico no diagnóstico, sempre como base em perícia especializada para que não se cometa equívocos, pois deixar de responsabilizar um médico, quando comprovado sua culpa, vai de encontro com os preceitos legais, ou no caso de condenar um profissional que no caso concreto não teve culpa, cometer-se-á injustiça. Logo, para que não haja nenhum equívoco quanto responsabilização do médico deve ser analisado o caso concreto.

Published: June 2024

De acordo com a Constituição Federal, os pais têm o dever de assistir, criar e educar os filhos até que completem a maioridade. No entanto, muitos genitores, em que pese promovam o sustento, abandonam os filhos afetivamente. Notadamente o abandono moral provoca sequelas psicológicas na criança ou adolescente, o que refletirá na vida adulta do indivíduo, não obstante, tal abandono viola valores protegidos constitucionalmente. Nesse sentido, o presente estudo pretende discutir sobre a possibilidade de reparação material nos casos de abandono afetivo paterno-filial. Para tanto, inicia-se a pesquisa analisando o afeto e o cuidado como valores protegidos pelo ordenamento jurídico brasileiro. Após, explicitar-se-á em que consiste o instituto da responsabilidade civil e sua relação com o Direito de Família e as posições doutrinárias e jurisprudenciais acerca do assunto. A metodologia empregada foi o método dedutivo, com pesquisa bibliográfica e documental, a partir da consulta de artigos, legislação e jurisprudência.

Authors: Polat Ahmet Batuhan , Akcay Ozgun , Kontas Fazli
Published: June 2024

Water levels in freshwater resources have been descending daily as global temperatures have risen and a coastal recession has occurred. The losses in these water basins have a significant influence on natural life. While drought is a global environmental issue, its consequences may be seen in Turkey. This study looks at the loss of water areas in Burdur Lake, one of Turkey’s major lakes, between 2010 and 2021. The areas were identified using supervised classification, and the classification process was carried out for 2010, 2013, 2016, 2019, and 2021, respectively. Furthermore, several drought detection metrics, such as land surface temperature, soil moisture values, Normalized Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), Palmer Drought Severity Index (PDSI), and precipitation amounts, have been evaluated for the study area between 2010 and 2021. The values of all drought detection indicators were also evaluated monthly for each year of the study. The analysis reveals abnormalities in all parameters, particularly in recent years, when compared to earlier years. Water areas decreased by 36.48% as a result of the classifications, whereas sandy areas increased by 89.85%. Again, the average values of various parameters used for drought detection over the years were compared. As a result, the indicator parameters gave reliable results as well as a means of monitoring the drought.
Study on triangulation network adjustment by Total Least Square Method
Authors: Kim Jung-Hyang , Kim Chol-Jin , Ri Myong-Hak
Published: June 2024

Generally, Least Squares (LS) Method treats only random errors of observation vector in adjustment function models. However, both observation vector and elements of coefficient matrix of adjustment function model contain random errors. Therefore, there is no guarantee that the result of adjustment by LS method is the global optimal solution. Total Least Square (TLS) method is a primary estimation method that treats random errors of observation vector and coefficient matrix in adjustment functional models. Since TLS method take into account both random errors of observation vector and coefficient matrix based on errors-in-variables model, it is possible to improve the accuracy compared with the result of LS method. So TLS method has been applied to different fields of science and technology including signal and image processing, computer vision,communication engineering and geodesy. However, weighted total least square (WTLS) method has been not applied in geodetic network adjustment problem compared with other fields widely. So the purpose of this paper is to summarize the algorithm of WTLS briefly and to propose an application method in adjustment of triangulation network. Key problem in application of WTLS to adjustment of geodetic network is to determine the weight matrix (or cofactor matrix) for elements of coefficient matrix in adjustment function model. In this paper proposed a method to determine cofactor matrix for errors of coefficient matrix in triangulation network, and verifies the effectiveness of suggested method through example applied to triangulation network.
The Nova Kakhovka dam collapse flooding as seen from Sentinel-1 SAR satellite images
Authors: Monti Roberto , Rossi Lorenzo , Reguzzoni Mirko
Published: June 2024

The destruction of the Nova Kakhovka dam in Ukraine on June 6th, 2023, produced an enormous flooding in the entire Kherson region. Thousands of people and agricultural fields were affected, bringing down an economy already devastated by the ongoing war. In addition to that, in the months prior to the collapse, the water level in the reservoir has been firstly decreased to a minimum, before rising it to an all-time maximum. Both these two situations are studied by means of Sentinel-1 SAR images, using the so-called change detection technique, with the aim of identifying those areas that got covered by water due to the Lake Kakhovka level rise and due to the flooding in the downstream region of the dam. The obtained results are then validated through comparison with optical images from Sentinel-2 and Landsat 9 satellites. The initial validation involves a visual assessment of both data types, followed by a more in-depth analysis that includes pixel classification of the optical images. This final step enables a precise quantification and comparison of the extent of the damage. It is clear that the increase of the water level before the dam collapse has worsened the extension and effect of the subsequent flooding.

Winning a scientific prize is always a welcome honor and receiving the Aselli Award in 2023 was a particularly pleasant surprise. The following text provides a brief summary of the research carried out by my group in Oxford that led to the discovery of the lymphatic endothelial marker LYVE-1 and its emerging role as a pivotal receptor controlling the entry of immune cells and metastatic tumor cells to lymphatic capillaries in peripheral tissues. As a basic scientist and relatively late comer to the field of lymphology, my hope is that a closer partnership of basic and clinical research will help explain the intricate workings of the lymphatics and improve the picture for patients
suffering from much neglected lymphatic disorders.
HANDLEY’S THREAD LYMPHANGIOPLASTY VS. BIOBRIDGE™ COLLAGEN MATRIX FOR LYMPHEDEMA THERAPY – OLD WINE IN NEW BOTTLES?
Authors: Witt M. , Ring A.
Published: June 2024

Lymphangioplasty is a technique of reconstructive lymphatic surgery where subcutaneous lymphatic neocollectors are created, using surgical threads, nanofibrillar collagen threads, plastic tubes or autologous tissue flaps. The history and success rates of these techniques are outlined and a classification for lymphangioplasty techniques is proposed. The use of absorbable surgical threads is suggested for modern attempts of thread lymphangioplasties. The results of such a thread lymphangioplasty should be compared with that of implanted nanofibrillar collagen threads or plastic tubes in order to evaluate whether the technique itself or the material used is responsible for the therapeutic success.
THE FATE OF IMPLANTED BIOBRIDGE™ COLLAGEN MATRIX – FINDINGS IN HISTOLOGY, SCANNING, AND TRANSMISSION ELECTRON MICROSCOPY
Authors: Witt M. , Ring A. , Stricker I. , Fruth E.
Published: June 2024

The technique of lymphangioplasty or capillary thread drainage was historically performed with subcutaneously implanted surgical threads. It has recently been revived by introducing a thread-like aligned nanofibrillar collagen matrix (BioBridge™). These collagen threads constitute subcutaneous neocollectors along which guided lymphangiogenesis is said to occur secondarily. We present for the first time a tissue examination of a 10-month implanted BioBridge™ sample with surrounding tissue from a human subject by histology, scanning and transmission electron microscopy.

Authors: Erickson R.P.
Published: June 2024

In 2015 the discovery of meningeal (dural) lymphatics was announced to much fanfare. The journal Science named this the second most important discovery of the year! Yet, they had actually been well described two and a quarter centuries earlier, in Italy, England and Holland. However, there was controversy about their existence because of the difficulties in studying them, also addressed two and a quarter centuries earlier. Their study had generated a very large literature and they were "textbook" knowledge. The reasons for this neglect are discussed emphasizing the current scientific milieu and the changing modes of evaluating scientists.

Authors: Imasuen Osasere Festus , Okoro Edesiri Godsday
Published: June 2024

Purpose: The primary aim of this study was to examine the effects of directors’ observable characteristics on market-level financial performance in Nigeria and South Africa via ex-post-facto research design.
 
Method: Cross-sectional data of one hundred and eleven (111) and one hundred and sixty-four (164) financial and non-financial firms were sampled in Nigeria and South Africa respectively from 2012-2021. Directors' observable characteristics used were board independence and gender diversity, and market-level performance indicators (Tobin’s Q and market-to-book-value ratios) Data were obtained from the annual reports and accounts of publicly quoted firms on Nigerian and Johannesburg Stock Exchanges. Data obtained were analyzed using descriptive, post-estimation and inferential statistical tools.
 
Results and Conclusion: The results of fixed and random effects regression revealed that while directors’ observable characteristics had significant effects on Tobin’s Q (Wald=39.87; Prob.=0.0000<0.05), an insignificant effects was found for market-to-book value (Wald = 6.27; Prob.=0.3933> 0.05) of firms in Nigeria and South. On the basis of the findings, it is recommended that management should engage in economic or business activities by way of investing more in capital assets or bonds to generate a high Tobin’s Q value for firms in Nigeria and South Africa
Implication of the Research: The implication is that directors’ observable characteristics can serve as a means of enhancing Tobin’s Q except market-to-book value
 
Originality/Value: There is the need for future researches to validate the model employed by using the identified directors’ observable characteristics which were not used in this current study.

Published: June 2024

Objective: The primary objective of this study was to delve into the intricate dynamics of how mindfulness and employee creativity collectively influence employee performance.
 
Method: The research design encapsulated the exploration of three direct relationships and a nuanced investigation of an indirect relationship elucidated through the mediating role of employee creativity between mindfulness and employee performance. Four distinct research hypotheses were rigorously tested, drawing upon data collected from an extensive survey involving two hundred and fifty-two employees within a prominent financial company in Indonesia. The survey instrument was administered through online questionnaires in two months, and the subsequent data analysis was facilitated through the employment of structural equation modeling and analysis of moment structures, a statistical program renowned for its efficacy in unraveling complex relationships within data structures.
 
Result and conlusion:  This study has confirmed the interplay among these variables integrally. The outcomes gleaned from this empirical exploration unveiled that mindfulness exerts a discernible influence on employee performance, manifesting through both direct and indirect pathways mediated by the critical intermediary role of employee creativity.
 
Originality: This nuanced finding accentuated the existence of partial mediating roles, presenting a substantial contribution to the literature by addressing the incongruities observed in previous studies pertaining to the intricate interplay among mindfulness, employee creativity, and employee performance. The robustness of the tested model is underscored by its ability to reconcile and provide insights into the seemingly inconsistent results reported in the extant literature.

Authors: Fischer Katherine , Xavier André
Published: June 2024

O presente trabalho objetiva (1) investigar a variação lexical e fonético-fonológica na libras através da reanálise de 21 produções referentes ao conceito ‘elevador’, originalmente coletadas por Xavier e F. Barbosa (2017) de 12 sinalizantes surdos do estado de São Paulo, e (2) comparar nossos resultados com os dos referidos autores. Para isso, diferentemente do estudo anterior, as produções reanalisadas foram primeiramente agrupadas por uma sinalizante surda usuária de libras como primeira língua em diferentes variantes lexicais com base em sua iconicidade (motivação) e não na sua semelhança formal. Posteriormente, foram analisados os aspectos fonético-fonológicos variantes e estáveis nas produções de cada variante lexical por meio de sua comparação. Como resultado, observou-se diferença em relação no número de variantes lexicais nos dois estudos, mas semelhanças nos resultados relacionados à variação e à estabilidade fonético-fonológicas.
Na fala tem. Mas há na escrita? Reflexões preliminares sobre a norma de referência na escrita acadêmica.
Authors: Da Cruz Barros Daniela Samira
Published: June 2024

A norma-padrão idealizada no Brasil vem de uma origem lusitanizada e, desde o início de sua implementação na nossa cultura, já estava fadada ao fracasso por estar totalmente distante do senso linguístico dos mais de 80% de analfabetos que habitavam o país no final do século XIX, ou seja, já nasceu sem ressonância social, ambientada em contexto de uma pequena elite letrada (Faraco, 2023). Ter e haver sempre concorreram no Português e existem muitos estudos relatando as mudanças diacrônicas dessa dupla. O que vemos atualmente é uma preferência, quase categórica, pelo verbo ter em detrimento do verbo haver na fala brasileira (Callou; Avelar, 2000; Lucchesi, 2022). A partir da ideia de que existem no Brasil outros padrões de referência (Faraco, 2008, 2015, 2020) se sobrepondo à norma-padrão prescrita pela gramática tradicional, buscou-se identificar em que medida a variação ter/haver existencial aparece na escrita acadêmica. A pesquisa é pautada nos estudos da Sociolinguística Laboviana (Weinreich, Labov, Herzog, 2006 [1968]), que considera a língua em uso, em seu contexto heterogêneo, e pretende sistematizar fatores que condicionam as variações linguísticas. Há ainda um panorama das reflexões mais recentes, no contexto brasileiro, sobre norma e diversidade linguística (Lucchesi, 2015; Vieira, 2018; Vieira, Lima, 2019). Nossos dados foram extraídos de publicações de revistas eletrônicas da USP e da UFRJ: são textos escritos e lidos por uma parcela considerada mais escolarizada da população, que consome e pratica a escrita acadêmica, lê e escreve, periodicamente, segundo modelos dos gêneros textuais acadêmicos, relativamente estáveis em sua produção. Optou-se por investigar textos de Comunicação Social e Direito, duas áreas que atuam essencialmente por meio da expressão linguística. Os resultados indicam que os produtores de textos acadêmicos se prendem a formatos específicos de gêneros e linguagens, corroborando a manutenção da forma mais conservadora, mas que o ter existencial vem ganhando espaço, sobretudo ao selecionar argumentos mais concretos e humanos, não sendo exemplo, portanto, de variante recusada nem na escrita acadêmica. Assim, identificamos diferentes padrões de referência sendo praticados pela parcela mais escolarizada da população, dentre os quais convivem os propostos pela chamada norma-padrão tradicional e outros padrões, convivência que denuncia uma norma de referência para a escrita que acomoda pluralidade, conforme propõe Vieira; Lima (2019).

The paper describes the process of designing the cutting tool feed drive of a special metalworking machine, which due to the circuit solution and automatic control system will increase the productivity of processing one cell of wafer background on sheet material up to 10–15 seconds. On the basis of the analysis of the technology of milling of a given regular pattern of wafer background and peculiarities of the equipment operation it proposed to replace the traditional ball bearing gear in the cutting tool feed drive with a flat combined crank-slide mechanism. Geometrical parameters of the lever transmission mechanism calculated in accordance with the known dimensions of the regular cell pattern and the recommended value of the angle of motion transmission. The analysis of kinematic and power characteristics of the lever mechanism allowed to justify the technical characteristics of the electric motor. In order to realize the required trapezoidal law of the output link speed change, the inverse problem of kinematics solved, numerical values of the instantaneous angular velocity of the input crank and pulse control signals to the servomotor obtained.

The work analyzes the process of bending the sheet work piece to obtain shaping of sheet metal parts and profiles. The analysis is carried out on the basis of strength calculations of elastoplastic bending of the metal plate. When pressing such a plate, in practice, a spring effect is observed when the curved blank changes its shape under the influence of residual elastic deformations at the end of the pressing process. To compensate for the spring effect, it is necessary to determine the values of elastic and plastic deformations in the sheet blank. The work considers the method of calculation of these values on the basis of available experimental works. Conclusions have been drawn and practical recommendations can be used in the process of setting process parameters for pressing sheet blanks.

A new method for measuring electric field strength is proposed. The method is based on the mean value measurement method, which uses a dual electroinduction spherical sensor. The use of the dual sensor for the method implementation allows to extend the functionality of the method by mean value. The method of measurement by the mean value assumes simultaneous measurement of two values of intensity E1 and E2 in one point of electric field with opposite sign errors. As the theory of construction of the new method has shown, it is possible to determine not only the measurement result as an average of two values of the strengths, but also to estimate the error of the measurement result and tentatively determine the distance to the field source. In order to determine the distance to the field source, a coefficient of the ratio of the two found strengths at each point of the field is introduced, by which the empirical dependence of the relative distance to the field source is found. The relative distance is the ratio between the radius of the spherical sensor and the distance to the field source. By determining the relative distance at each measuring point according to this relationship and substituting it into the known expression for the error, the error of the result at the measuring point is determined. The relative distance is also used to determine the distance to the field source. Thus, the new method of measurement allows to increase the accuracy of measurement of electric field strength, determined by the relative distance to the source of the field.

Objetivo: Analisar os custos de procedimentos de parto vaginal e cesárea em um hospital de alto risco de Pernambuco entre os anos de 2019 e 2020. Métodos: Estudo exploratório descritivo, retrospectivo, de avaliação econômica e viabilidade financeira, conduzido em uma maternidade referência do estado de PE. Utilizando o método de custeio por absorção, a pesquisa envolveu coleta de dados documental, entrevistas e consultas ao DATASUS. Resultados: Verificou-se que um total de 4006 partos foram realizados na instituição de saúde do estudo entre 2019 e 2020. Constatou-se que 41.51% dos partos foram vaginais enquanto os partos cesáreos representaram cerca de 58.49% do total, com aumento de 21,6% das cesarianas de 2019 para 2020. Em 2019, o custo total do parto vaginal foi de R$ 37.900,00, enquanto o custo total para o parto cesáreo alcançou R$ 234.895,50. Em 2020, esses números aumentaram significativamente durante a pandemia de COVID-19, com o parto vaginal custando R$ 50.888,15 e o cesáreo R$ 411.603,69 (valores anuais). Conclusão: Verificou-se aumento nos custos dos partos, especialmente cesáreas, com leve aumento no período pandêmico, evidenciando desafios financeiros e operacionais. A gestão eficiente foi demonstrada pela diferença entre os custos hospitalares e os repasses do Sistema Único de Saúde.
The Development of Air Navigation in West-Germany After 1945: The Story of Rhein Control

Published: June 2024

This is a historical facts report and commentary on the development of the German Air Traffic Control Centre RHEIN CONTROL as formerly operated by the United States Air Force in Europe (USAFE) and the former German Federal Administration for Air Navigation Services (BFS), assisted by the German Air Force (GAF) at Birkenfeld-Nahe and Frankfurt/Main in Germany. RHEIN CONTROL was and still is an upper airspace air traffic control (ATC) centre, formerly responsible for South Germany only, but now also covering all of former East Germany (Berlin UIR). This report is written by a former air traffic controller and air traffic control expert, who meanwhile actively spent 50 years in the ATC profession worldwide, and has had first served 25 years with the German Federal Administration for Air Navigation Services (Bundesanstalt für Flugsicherung) in upper airspace area control operations, ATC planning and experimentation.
Die Entwicklung der Flugsicherung in Deutschland Teil 3, Deutsche Flugsicherung im Kalten Krieg Die FS-Zentrale Rhein Control von 1957 bis 1977

Die Dokumentation von Frank W. Fischer behandelt die Entwicklung der deutschen Flugsicherungs-Zentrale des oberen Luftraums Süddeutschlands RHEIN UAC mit dem Funkrufzeichen RHEIN CONTROL, die auf dem Erbeskopf im Hunsrück von 1957 bis 1968 und ab 1968 bis 1977 am Flughafen Frankfurt am Main betrieben wurde. Die Flugsicherungs-Zentrale Rhein UAC war allen über Deutschland im oberen Luftraum fliegenden Fluggesellschaften und militärischen Einheiten in der Nachkriegszeit bekannt. Zudem war diese Flugsicherungs-Zentrale seit den 1950’er Jahren bereits mit Verkehrsproblemen konfrontiert, mit denen andere Flugsicherungs-Zentralen und Flugsicherungs-Dienstleister in Europa erst viele Jahre später zu kämpfen hatten. Rhein UAC war die Wiege einer Vielfalt von Methoden und betrieblichen Verfahren für die Flugverkehrskontrolle, die seinerzeit bei anderen Flugverkehrsdiensten unbekannt waren.Es war die Zeit des Kalten Krieges. Deutschland war geteilt und die Luftstreitkräfte der Besatzungsmächte übervölkerten den Luftraum mit fast 2.000 Kampfflugzeugen am Tag sowie in der Nacht. Militärische Flugoperationen, von denen die Bevölkerung nie etwas erfahren hatte. Der Kalte Krieg - das Gegenüber von Ost und West - spielte sich auch weit über den Wolken im oberen Luftraum ab. Aber Vieles bezüglich der zivilen und militärischen Flugverkehrskontrolle war noch nicht geregelt. Manches noch gar nicht erfunden. Insbesondere die Mischung ziviler und militärischer Betriebs- und Kontrollverfahren war einmalig. Die Einmaligkeit bestand aus der Kombination des gemeinsamen Betriebs sowie der Belegschaft und der Flugsicherungskontrollverfahren. So leiteten drei Personal-Kontingente, nämlich US Air Force, Bundesanstalt für Flugsicherung und Bundeswehr, Flüge aller Verkehrskategorien. Dies betraf ebenso alle militärischen Ausbildungs- und Sonderflüge sowie die Zielflüge großer NATO Luftmanöver. Auf 717 Seiten beinhaltet diese Dokumentation in deutscher Sprache 266 Abbildungen und 71 Anhänge sowie eine Vielfalt aufschlussreicher Quellendokumente und Berichte über damalige Unfälle und Vorfälle, die der Öffentlichkeit bis zum heutigen Tage nicht bekannt waren.
Exact Factorization of the Photon-Electron-Nuclear Wavefunction: Formulation and Coupled-Trajectory Dynamics
Authors: Sangiogo Gil Eduarda , Lauvergnat David , Agostini Federica
Published: June 2024

We employ the exact-factorization formalism to study the coupled dynamics of photons, electrons, and nuclei at the quantum mechanical level, proposing illustrative examples of model situations of nonadiabatic dynamics and spontaneous emission of electron-nuclear systems in the regime of strong light-matter coupling. We make a particular choice of factorization for such a multi-component system, where the full wavefunction is factored as a conditional electronic amplitude and a marginal photon-nuclear amplitude. Then, we apply the coupled-trajectory mixed quantum-classical (CTMQC) algorithm to perform trajectory-based simulations, by treating photonic and nuclear degrees of freedom on equal footing in terms of classical-like trajectories. The analysis of the time-dependent potentials of the theory along with the assessment of the performance of CTMQC allow us to point out some limitations of the current ap- proximations used in CTMQC. On the other hand, comparing CTMQC with other trajectory-based algorithms, namely multi-trajectory Ehrenfest and Tully surface hopping, demonstrates the better quality of CTMQC predictions.

Chiral annulated indoles are unique molecules with numerous examples of this structural motif in natural and medicinally relevant compounds. However, accessing these enantioenriched molecules, particularly indoles annulated on the benzene ring, has been limited and often overlooked. This study presents a highly efficient organocatalytic protocol for synthesizing chiral annulated indoles. The efficiency of the developed methodology is demonstrated by its broad substrate scope, excellent functional group tolerance, and the use of only 1 mol% of a chiral conjugated acid of catalyst. Additionally, the study of the observed regioselectivity, gram-scale reaction, and various follow-up transformations underscore the potential of this method.
