Inverse Element for Surreal Number
Authors: Pąk Karol
Published: November 2024

Conway’s surreal numbers have a fascinating algebraic structure, which we try to formalise in the Mizar system. In this article, building on our previous work establishing that the surreal numbers fulfil the ring properties, we construct the inverse element for any non-zero number. For that purpose, we formalise the definition of the inverse element formulated in Section Properties of Division of Conway’s book. In this way we show formally in the Mizar system that surreal numbers satisfy all nine properties of a field.
Descendientes de africanos en la Independencia
Authors: Mosquera Mosquera Sergio Antonio
Published: November 2024

Descendientes de africanos en la Independencia es el octavo volumen de la Biblioteca Afrocolombiana de las Ciencias Sociales. Su autor nos muestra con un lenguaje sencillo y preciso por qué al libertador Bolívar le interesó poco, o casi nada, dar la carta de libertad jurídica a los afros. A pesar de que lo pudo hacer en 1821 en el Congreso de Cúcuta, se negó a hacerlo; por el contrario, mandó a fusilar a líderes y héroes negros y mulatos que participaron en el proyecto independentista, tales como Piar y Padilla. Al desenredar esta falsa trama histórica y al desmitificar la figura del héroe Bolívar, Sergio Mosquera está haciendo etnoeducación, etnohistoria; está reinventando el paradigma de las ciencias sociales en Colombia.

Este proyecto editorial de las ciencias sociales afrocolombianas no será en vano si los lectores indistintos de la Biblioteca se atreven a elucidar una ontoepistemología de la diáspora africana en Colombia, escrita por subjetividades reflexionantes afros; pues, siempre fuimos visibles, tú me invisibilizaste… ahora es tiempo de que te pongas en nuestro lugar… Escúchanos desde el marco de la igualdad y la tolerancia que estas ideas aquí contenidas puedan darte, estimado lector…

Methyltransferase-like 14 promotes the tumorigenesis and proliferation of pancreatic cancer cells through myc proto-oncogene signaling pathway
Authors: Li Junru , Wang Peng , Liu Fei , Li Yuanyuan , Wu Youyou , Wang Fengbo , Du Jundong
Published: November 2024

Objective:

Pancreatic cancer is characterized by low survival rate and rapid deterioration. Methyltransferase-like 14 (METTL14), as N6-methyladenosine (m6A) methyltransferase, is closely related to tumor progression. The purpose of this study is to look into how METTL14 affects pancreatic cancer tumorigenesis, cell division, and apoptosis.

Material and Methods:

We examined and contrasted the levels of METTL14 protein and messenger RNA expression in human pancreatic ductal cells and human pancreatic cancer cells. After silencing or upregulating METTL14, the proliferative ability, migration ability, and cell apoptosis of pancreatic tumor cells was detected by colony-forming assay, wound scratch healing assay, cell counting kit 8 assay, and terminal deoxynucleotidyl transferasemediated 2’-deoxyuridine 5’-triphosphate-biotin nick end labeling assay. Following the use of c-Myc inhibitor (10058-F4), western blot analysis was carried out to investigate the key factor expression and c-Myc signaling pathway activation status.

Results:

METTL14 was preferentially expressed in human pancreatic cancer cells PANC-1 and SW1990 than in human normal pancreatic duct cells human pancreatic nestin-expressing cells (HPNE) (P < 0.001). Overexpression of METTL14 increased the tumorigenic and proliferative ability of pancreatic cancer cells. Overexpression of METTL14 decreased apoptosis rate. Western blot assay showed that nucleus b-catenin increased when METTL14 was overexpressed, and nucleus b-catenin decreased when METTL14 was silenced in PANC-1 cell (P < 0.01). The protein expression of other key factors, such as c-Myc, matrix metalloproteinase (MMP)-9, and MMP-2, were also affected. The use of c-Myc inhibitor (10058-F4) on the basis of OE-METTL14 reversed the effect of the overexpression of METTL14 on promoting the tumorigenesis and cell proliferation of pancreatic cancer cell lines PANC-1 and SW1990.

Conclusion:

METTL14 promoted the tumorigenesis and proliferation of pancreatic cancer cells by the c-Myc signaling pathway.
Fibronectin type III domain containing protein 5/irisin alleviated sepsis-induced acute kidney injury by abating ferroptosis through the adenosine 5'-monophosphate-activated protein kinase/nuclear factor erythroid-2-related factor 2 signaling pathway
Authors: Gui Shenghao , Zhu Chaochao , Lu Yunfeng
Published: November 2024

Objective:

Ferroptosis has been described in association with acute kidney injury (AKI)-induced sepsis. Fibronectin type III domain containing protein 5 (FNDC5)/irisin plays a crucial role in renal protection. The objective of this study was to investigate whether FNDC5/irisin is involved in AKI-induced sepsis by modulating ferroptosis, and the molecular mechanisms that may be involved.

Material and Methods:

A sepsis-induced AKI model was built in vivo and in vitro through lipopolysaccharide (LPS) intervention. FNDC5, adenosine 5'-monophosphate-activated protein kinase (AMPK), phospho-AMPK (p-AMPK), nuclear factor erythroid-2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), glutathione peroxidase 4 (GPX4), and acyl-CoA synthetase long-chain family member 4 (ACSL4) concentrations in cells and mouse kidney tissues were appraised by Western blot. Pro-inflammatory cytokines concentrations in cell supernatants and mouse kidney tissues were appraised by enzyme-linked immunosorbent assay. Fe2+ concentration in cells and mouse kidney tissue was appraised by kit. The apoptosis rate of cells and mouse kidney tissue was measured by flow cytometry. Automatic biochemical analyzer was to test serum creatinine (SCr) and blood urea nitrogen (BUN). The kidney tissue sections from each groups were observed by hematoxylin and eosin staining.

Results:

LPS abated FNDC5 concentration in human kidney-2 cells and mouse kidney tissue (P < 0.001). Overexpression of FNDC5 can abated proinflammatory cytokines concentrations in cells and mouse kidney tissue (P < 0.01). Meanwhile, overexpression of FNDC5 can boost GPX4 protein concentration, abate ACSL4 protein, and abate Fe2+ concentration in cells and mouse kidney tissues (P < 0.05). In addition, the overexpression of FNDC5 can reduce the rate of apoptosis (P < 0.01). In vivo experiments showed that FNDC5 overexpression reduced serum BUN and SCr concentrations and alleviated pathological damage in the mouse renal tissues (P < 0.05) and exhibited a certain renal protective effect. FNDC5 overexpression can boost p-AMPK/AMPK, Nrf2, and HO-1 protein concentrations (P < 0.01).

Conclusion:

FNDC5/irisin improves sepsis-induced acute renal injury by abating ferroptosis through the AMPK/Nrf2 signaling pathway.

Authors: Greenberg Kailah , Chang Kristina , Supple Matthew , Goverman Jeremy
Published: November 2024

Background. With the increase in lithium-ion battery-powered technology, clinicians have observed an increase in burn injuries. Typically, these injuries come from malfunctions in e-cigarettes, e-scooters and bikes, and even mobile phones. To the best of the authors' knowledge, this is the first reported case of a patient burned by the lithium-ion battery pack on an electric sock, which is commonly worn by skiers, snowboarders, and winter hikers. Case Report. The patient presented shortly after the initial injury with a full-thickness burn with eschar and surrounding cellulitis. He was treated with oral antibiotics, surgical excision in clinic, and local wound care. The patient was offered surgical wound closure but opted to continue local wound care. Although slow, the patient saw complete wound closure in approximately 3 months with minimal scarring and no further complications. Conclusion. With lithium-ion technology on the rise, it is important to understand the risks and care necessary to keep these devices safe for everyday use.
Кураторство русскоязычных литературных проектов во время военных действий
Authors: Лехциер Виталий
Published: November 2024

Эссе посвящено кураторам русскоязычных литературных проектов (редакторам, организаторам акций, издателям актуальной литературы, создателям форматов литературной учебы), реализующихся во время военных действий. Текст основан на эмпирическом качественном исследовании точек зрения и мотивов литературных кураторов, находящихся как в России, так и за ее пределами. Среди последних – литературные кураторы, давно живущие за рубежом или эмигрировавшие из России за последние полтора года. В эссе исследуются причины закрытия или приостановки кураторами своих литературных проектов в России и мотивы создания новых проектов или продолжения старых. В тексте выявляются точки зрения литературных кураторов на возможные и реальные цели русскоязычных литературных проектов во время войны. Автор обращает внимание на специфику кураторских позиций и действий в зависимости от локации проекта (в России, за ее пределами, в столичных или региональных российских городах), а также возраст куратора. Кроме того, исследование выявляет спектр мнений литературных кураторов по поводу громких дискуссионных проблем, связанных с судьбой русскоязычных литературных проектов во время войны: отношение к сотрудничеству с государственными культурными институциями, практике фильтрации участников проектов в зависимости от политической позиции, отношение к тезису об ответственности русского языка и литературы за военную агрессию и отношение к раздающемуся в адрес русскоязычных литературных проектов требованию прекратить работу, замолчать. В целом исследование показало, что кураторы трактуют сегодняшнее положение русской актуальной литературы как «новый андеграунд» и видят свою задачу в психологической и профессиональной помощи автору, политизации проектов, а также в документировании новой литературной эмигрантской среды.

Published: November 2024

Лингвистический поворот, произошедший в эпистемологии несколько десятилетий назад, привнес в изучение общественных процессов внимание к языку, которым говорят политики и которым говорят о политике. Любые политические действия нуждаются в объяснительных моделях, а также требуют соответствующего языка, способного объяснить эти действия не только принимающим решения лицам, но и более широкому кругу людей. Такой язык должен быть понятен и признаваем этим широким кругом. Другими словами, легитимация политических решений требует их объяснения, вписывания в более широкое представление об устройстве политики и общества. Без такой концептуальной рамки политики не бывает. Это означает, что для радикального поворота государственного курса деятелям режима нужна смена языка говорения о политике.

Vladislav Aksenov’s book whose title translates as The War of Patriotisms: Propaganda and Mass Moods in Russia during the Collapse of the Empire was published in 2023. This book was released in the popular science series What Is Russia? (Chto takoe Rossiia?) by Novoe literaturnoe obozrenie publishing house. Although this work is partly an adaptation of the author’s large monograph (Aksenov 2020) for a wider audience, the central theme of the 2023 book is narrower. Aksenov defines it as a combination of the history of ideas, images, and symbols, and the history of emotions to examine the phenomenon of patriotism in the Russian Empire from the early nineteenth century to 1917. Moreover, the psychological side of patriotic discourses and practices receives here central attention.

Эмоции в автобиографической памяти: герои и жертвы разных поколений
Authors: Граматчикова Наталья , Зевако Юлия
Published: November 2024

Авторов предлагаемого исследования объединяет интерес к эмоциональной составляющей памяти в документальных свидетельствах советской эпохи и меморативных нарративах о ней. Поляризованность рецепции исторического контекста 1930–1980-х годов привела к тому, что память о героях и «антигероях» фиксируется в двух разных типах архивных документов, которые на практике могли отражать этапы жизни одного и того же человека. Фокусируясь на понятии автобиографической памяти, авторы предлагают рассмотреть архивное наследие ветеранов эпохи индустриализации и рецепцию материалов следственных дел эпохи Большого террора через призму эмотивной лексики. Источниками исследования послужили коллекция воспоминаний ветеранов машиностроительного завода о времени их молодости и их вкладе в строительство завода в 1929–1933 годах, а также корпус полуструктурированных интервью с потомками репрессированных, взаимодействовавших со следственными делами своих предков. Ключевые задачи исследования состояли, с одной стороны, в том, чтобы проанализировать, каким образом эмоциональные режимы формирования документов в 1930-х и в 1960–1980-х годах влияют на трансляцию памяти о 1930-х годах; с другой – каким образом акторы межпоколенческой трансляции справляются с поляризованным меморативным контекстом. Уже на этапе формирования документы и эго-документы советского времени ограничивают эмоциональную палитру скриптора, а воспоминания передовиков производства обусловлены жанром не меньше, чем следственные дела. Смена исторического контекста и утрата предполагаемого читателя обоих типов документов создают необходимость интерпретационной работы для наших современников. При анализе воспоминаний ветеранов устанавливаются некоторые неочевидные причины эмоциональной редукции и определяются наиболее свободные для выражения эмоций композиционные позиции. Потомки репрессированных, сталкиваясь в текстах следственных дел с дефицитом эмоциональности и настраиваясь на сопротивление аффективной стилистике допросов и доносов, говорят в интервью о своей телесной включенности в коммуникацию с артефактом, помогающей пережить эмпатию по отношению к своему родственнику. Авторы приходят к выводу о продуктивности использования понятия «протезной памяти» (по Элисон Ландсберг) в автобиографическом нарративе как о «героях», так и о «врагах». Соположение документов разных эпох, объединенных рамкой автобиографической памяти, показывает, что «чувственный опыт» (авто)биографического нарратива может быть получен как ресурсами (авто)коммуникативной памяти, когда субъект ретроспективно осмысляет собственный жизненный опыт, так и механизмами культурной памяти – через стимулирование воображения и эмоций в качестве реакции на «документ эпохи», благодаря чему таковой наделяется личностным смыслом.

Время без обязательств: темпоральная множественность и устойчивость городской коммуны
Authors: Котельников Артем
Published: November 2024

В статье представлено этнографическое исследование коммуны Дом, одной из примерно десятка ныне существующих коммун Санкт-Петербурга, основанных на совместном проживании и ведении общего хозяйства людьми, не являющимися друг другу родственниками, в больших квартирах (некогда коммуналках или общежитиях). Жители Дома постулируют отсутствие оснований объединения, однако вместе с тем эта коммуна является одним из самых устойчивых и долгоживущих коммунальных сообществ города. Именно этот парадокс и рассматривается в тексте. В поисках источников устойчивости Дома автор обращается к оптике антропологии времени и анализирует сложившуюся в нем темпоральную множественность.В тексте рассматриваются конфликты между группами членов коммуны, действующими в рамках разных темпоральностей: конфликт вокруг проектного будущего сообщества, в котором сторонники Дома как проекта были вытеснены защитниками идеи коммуны без четко сформулированного представления о ее целях и будущем, а также конфликт между группами, предпочитающими разные варианты дневного цикла, соединяющего домашнюю и рабочую сферы.Следуя концепции Ольги Бредниковой, среди коммунальных темпоральностей автор выделяет длительную временность – темпоральность, предполагающую отказ от определенных будущего и прошлого в пользу настоящего, внутри которого все реалии временны. Длительная временность составляет основу особой устойчивости Дома и характеризует не отдельных субъектов, а организацию сообщества. Его жители не просто действуют в ней, а целенаправленно ее воспроизводят, что позволяет им избежать жестких правил и иерархий и благодаря этому сохранять устойчивость при внутреннем разнообразии темпоральностей и жизненных предпочтений.

Building an Informal Transnational Information Network on the USSR from Paris: An Outside Perspective on Soviet Life in 1923–1939
Authors: Pashkeeva Natalia
Published: November 2024

The article presents findings on the informal network exchanging and disseminating information about socioeconomic and political trends in the USSR in 1923–1939. This network, formed through interactions between the workers of the American Young Men’s Christian Association (YMCA) and Soviet émigrés in Paris, was supported by American and British academics, public figures, and religious actors. Their goal was to improve public information and raise awareness of repressions in the USSR. The central argument is that this network emerged spontaneously to meet the demand from religious and public actors for regular, objective, and reliable information amid polarized Western views on Soviet experiment in building socialism and communism in the 1920s–1930s. It primarily distributed translations into English of Soviet press articles, official documents, laws, propaganda, and literature. Personal accounts from émigrés or travelers to the USSR were taken into account, but rarely cited in the disseminated materials. An exception highlighted is the 1932–1933 famine, which was omitted from the official Soviet documentation and press. The article reconstructs the information network through the individuals’ professional and personal connections, examining covered topics, methods of information presentation, key communication channels, and obstacles. It briefly discusses the spontaneous involvement of the network’s workers in attempts to influence political and diplomatic decisions, including the restoration of diplomatic and trade relations with the USSR by the British government in 1929 and the US administration in 1933.

The Origin of Oltu Stone (Turbostratic Carbon) from the Olur-Tortum Area: A Natural Composite Carbonaceous Material (Erzurum, Türkiye)
Authors: Helvacı Cahit , Hatipoğlu Murat , Passeri Daniele , Konak Neşat , Kınacı Eyyüp Hikmet
Published: November 2024

This study focuses on geological, microstructural, oxygen isotopic, and thermogravimetric investigations of Oltu stone, which is the most important turbostratic carbonaceous material in Turkey.
The results of our investigations indicate that the carbonaceous Oltu stone material (specific gravity of 1.317) is not an organic material, such as jet, derived from fossilized wood. Rather, it is composed of a carbonaceous phase intermediate between amorphous carbon and crystallized graphite (termed turbostratic carbon), that is intercalated with flysch and formed by the reduction of seeping magmatic carbon dioxide during the diagenesis of Upper Jurassic-Lower Cretaceous marine sediments. Oxygen isotope analyses (SMOW) (using EA-IRMS) of both Oltu stone (δ18O = +37.2‰to +40.8‰) and the enclosing flysches (δ18O = +10.3‰ to +12.3‰) suggest that the nodules formed during diagenesis at a temperature of around 50 ℃. However, they are enclosed in flysches whose grains are derived from rocks that formed at significantly higher temperatures, perhaps above 100 ℃.
The main industrial use of Oltu stone is as host material for diamond coating, as the sp3 bonds in the material can provide nucleation sites for diamond crystals and improve the nucleation rate at the early stage of diamond deposition on turbostratic carbon.

Transport characterization of solid-state Li2FeS2 cathodes from a porous electrode theory perspective
Authors: Bernges Tim , Ketter Lukas , Helm Bianca , Kraft Marvin , See Kimberly , Zeier Wolfgang
Published: November 2024

The abundance and cost of resources for current state-of-the-art cathode active materials makes the search for alternative cell chemistries inevitable. Nonetheless, especially in solid-state batteries, establishing new cell chemistries comes at the challenge of optimizing the transport of both charge carriers, electrons and ions, through the electrode. Limitations in transport of either species lead to underutilization of the electrode caused by insufficiently contacted particles and/or nonuniform reaction rates and state-of-charge gradients through the electrode. In this work, we investigate the capabilities of Li2FeS2 as alternative active material in all-solid-state cathodes by thorough investigation of the initial utilization and rate capability as a function of the cathode loading. The cathode loading is increased from 1.8 to 7.3 mAh·cm−2 by increasing the fraction of active material from 32 to 74 vol.%, and the thickness of the composite electrode from 73 to 145 μm. Careful characterization of the effective electronic and ionic transport, and consideration of the δ-parameter from porous electrode theory, guides the understanding of the electrode performances. With that, this work shows that Li2FeS2 solid-state cathodes with high areal loadings and gravimetric energy densities can be realized.
DFT-based Polarizable Ion Models for Molten Rare-earth Chlorides: from Lanthanum to Europium
Authors: Goloviznina Kateryna , Notarangelo Maria-Chiara , Tranchida Julien , Bourasseau Emeric , Salanne Mathieu
Published: November 2024

We developed a systematic polarizable force field for molten trivalent rare-earth chlorides, from lanthanum to europium, based on first-principle calculations. The proposed model was employed to investigate the local structure and physico-chemical properties of pure molten salts and their mixtures with sodium chloride. We computed densities, heat capacities, surface tensions, viscosities and diffusion coefficients and disclosed their evolution along the lanthanide series, filling the gaps for poorly studied elements, such as promethium and europium. The analysis of the local arrangement of chloride anions around lanthanide cations revealed broad coordination number distributions with a typical [from six to nine]-fold environment, the maximum of which shifts towards lower values with the increase of atomic number as well as upon dilution of the salt in sodium chloride. The neighbouring lanthanide-chloride complexes were found to be connected by sharing a corner or an edge of the corresponding polyhedra.
Doping and Annealing Conditions Strongly Influence the Water Oxidation Performance of Hematite Photoanodes
Authors: Nguyen Triet , Ren Jiawen , Murdoch Billy , Lipton-Duffin Josh , MacLeod Jennifer , Gomez Daniel , van Embden Joel , Della Gaspera Enrico
Published: November 2024

Hematite (α-Fe2O3) is one of the most promising semiconductors for solar water splitting due to its high theoretical efficiency and low cost. However, its poor electronic properties strongly limit its performance. Furthermore, the impact of composition and processing conditions on such properties, and on the water splitting efficiency, is poorly understood. Here, we unravel the role of these contributions, and provide guidelines for the fabrication of efficient hematite photoanodes. Aliovalent doping with tin and fluorine is found to improve the electrical conductivity of hematite, leading to higher performances. Annealing in inert atmosphere, which is conventionally used to create oxygen vacancies, is found not to affect undoped hematite. However, a marked effect has been observed in doped hematite, and a model describing dopant activation rather than oxygen vacancy formation has been proposed. The synergy between the presence of both dopants and the annealing conditions provides optimal electrical properties, that enable to increase the hematite thickness leading to enhanced light absorption, limiting the detrimental charge recombination issues observed in undoped films, or even in doped films processed in excess oxygen. Our work provides a deeper understanding of the interplay between all these processing factors, resulting in hematite photoanodes with increased performance.
Discriminant Analysis Optimizes Progress Coordinate in Weighted Ensemble Simulations of Rare Event Kinetics
Authors: Prabhakar Praveen Ranganath , Ray Dhiman , Andricioaei Ioan
Published: November 2024

Calculating the kinetics of rare-but-important conformational transitions in complex biomolecules is a significant challenge in computational biophysics. Because of the long timescales needed to observe such processes, regular molecular dynamics simulations are too slow to sample these events by direct integration of the equations of motion. Recently, the weighted ensemble method has gained significant popularity for its ability to compute the rates of conformational transitions in biomolecular systems using unbiased simulations. However, the progress coordinate(s) of the weighted ensemble simulation should be carefully designed to capture the slow degrees of freedom of the system. Here, we demonstrate the application of a machine learning approach, harmonic linear discriminant analysis, which builds a predictive model for class membership, to design progress coordinates for weighted ensemble simulations. We test the accuracy and efficiency of this technique for computing the kinetics of the conformational transition of alanine dipeptide and the unfolding of a small protein. The key advantage of our data-driven approach is its minimal system knowledge requirement, which potentially extends its applicability to more complex and physiologically relevant systems.
The Asymmetric Olefinative Conjugate Addition
Authors: Vaghi Francesco , Soppelsa Piero , Wurst Klaus , Giulia Licini , Orlandi Manuel
Published: November 2024

The asymmetric olefinative conjugate addition (AOCA) is presented, which involves an enantioselective conjugate addition to an olefin activated by a traceless electron-withdrawing group, which then allows for an olefinative quench with a carbonyl com-pound. This approach is demonstrated by the Cu-catalyzed enantioselective conjugate addition of organoboron and organozinc reagents to an alkenyl phosphonate, followed by quenching with a carbonyl compound to yield the corresponding alkene via Horner-Wadsworth-Emmons olefination. This one-pot sequence efficiently produces chiral internal olefins, addressing a common limitation of Cu-catalyzed enantioselective allylic substitutions, which typically only generate terminal alkenes. The versatility of this strategy is showcased through the synthesis of various structurally diverse products with high yields, complete diastereocon-trol, and enantiomeric ratios of up to 98:2.

aim: Mental wellbeing has been one of the most prominent health concerns in Aotearoa New Zealand and has only been exacerbated
by the COVID-19 pandemic. Here we explored factors associated with anxiety and happiness in a mid-pandemic climate in Aotearoa.
methods: Analyses were performed on the anxiety and happiness scores from the wellbeing survey in December 2020 (Statistics NZ
Tatauranga Aotearoa; 30,000 responders contacted for the Household Labour Force Survey). Correlations and general linear models
were used to identify significant predictor variables related to anxiety and happiness scores.
results: A number of factors correlated with both anxiety and happiness, including loneliness, physical health, family wellbeing,
financial wellbeing, age and gender. After controlling for many ethnically stratified social burdens, Māori and Pacific populations
demonstrated higher levels of happiness. Discrimination was only associated with anxiety, while generalised trust, trust in the police
and in the health system all related to happiness.
conclusion: Anxiety and happiness in a mid-pandemic environment shared many related variables spanning physical, social and
financial domains. Additionally, anxiety was associated with greater levels of discrimination, and happiness with trust in public
services. Here we provide a window into the state of mental wellbeing in Aotearoa during a global health crisis.

The article deals with the issue of financing education in the field of physical culture and sports in Ukraine. As part of this, the main indicators of the state budget of Ukraine in terms of financing the development of physical culture and sports were analyzed, which indicate the lack of growth dynamics of financial support in this area. This can be a demotivating factor for future specialists in physical culture and sports, because budgetary funding takes the lion's share in financing the sector of physical education and sports. It is proposed to identify sports public organizations as one of the alternative entities that will act as an authorized customer for the training of specialists under educational programs in the field of physical culture and sports, it is proposed to consider. The introduction of budgetary/nonbudgetary financing of sports public organizations involves the creation of a system of subjects, principles and conditions of financing (legal obligations, economic justification, competitive principles in the form of the composition of the competitive commission and selection criteria). The improved approach allows taking into account the specific current needs of society and the effective use of available funding sources (budgetary or extra-budgetary). In turn, this contributes to the expansion of opportunities and gives new rights to public organizations that ensure the development of various types of sports. The proposed approach to the construction of a financial mechanism of state support for the development of higher education in the field of physical culture and sports allows to minimize the risks of the influence of external factors on educational activity and ensures compliance with such principles as: continuity, flexibility, correspondence of cost-result categories and efficiency, in the formation of state policy in the field of higher education, as well as the policy of higher education institutions.

En algún momento de nuestras vidas, podemos encontrarnos en situaciones en las que solicitar atención médica es necesario por ser víctimas o testigos de un incidente que sea considerado una urgencia o emergencia.
El bien más preciado del ser humano es la salud, ya que con ella podemos llegar a cumplir nuestras metas de vida. Sin embargo, muchas veces la descuidamos al poner como prioridad otras cosas.
Cuando hablamos de una situación de emergencia, nos referimos a la aparición repentina de complicaciones en un determinado lugar o situación, cuyas causas son accidentales o suficientemente diversas, lo que genera la necesidad de ayuda inmediata para el paciente. Una situación de emergencia no supone un riesgo inmediato de muerte, pero dependiendo de las circunstancias, puede ocurrir y siempre se requiere una intervención inmediata.
Pensando en el reto que representa tener una buena salud, hablemos brevemente de cuáles son las enfermedades más frecuentes en el Ecuador, tomando en cuenta que en algunos casos podremos incluso llegar a necesitar una atención hospitalaria.
Dentro de estas consideraciones, el libro explica muchos aspectos importantes de las urgencias y enfermedades más comunes del Ecuador, como su desarrollo histórico, etiológico, sintomatología, factores de riesgo, diagnóstico y tratamiento.
El libro está destinado a lectores interesados en conocer las características generales, así como, el manejo y abordaje de las enfermedades más comunes del mencionado país suramericano, de manera clara y precisa.
Sería de gran utilidad tener en un solo texto una base de conocimientos completa, tanto con explicaciones básicas como con instrucciones muy detalladas, sobre las patologías que se encuentran en el servicio de urgencias de cualquier hospital o centro médico del mundo.

Buildings resulting from construction projects are durable assets and decisions related to construction projects have enduring impacts. In many cases, building owners prioritize only the initial costs, such as building design, construction, and equipment costs, while neglecting the future operation and maintenance costs. This research studies life cycle costing (LCC) analysis to evaluate the financial feasibility of urban housing. The LCC calculates all the costs incurred and benefits during the building's operation. The cost is generated from construction, operational, and maintenance costs. At the same time, the benefit breaks down into flat rental costs, retail rental costs, and parking costs. The costs incurred are estimated over 25 years, and the parameters of feasibility are net Present Value (NPV), Benefit-Cost Ratio (BCR), and Internal Rate of Return (IRR). The study generates negative NPV, BCR < 1, and 0.61% of IRR. It indicates that the project is not feasible. This research gives alternatives to make the project feasible. This study employed a trial-and-error approach to ascertain the viability of investing in flat rentals by systematically adjusting rental rates. Incremental adjustments to rental rates are tested by a series of rate hikes of 50%, 100%, 150%, and 200% using a trial-and-error approach. The project will become feasible if the flat rate increases to 150-200% of the initial rental rate.
