Evaluasi Performa Material Penutup Atap Terhadap Penghematan Energi Bangunan
Authors: Aziz Azwan
Published: June 2024

Atap sebagai komponen penutup bangunan rumah, khususnya di daerah tropis, merupakan permukaan bangunan yang paling banyak terekspos oleh radiasi sinar matahari. Oleh sebab itu perannya harus dioptimalkan dalam membendung radiasi panas matahari agar kenyamanan termal ruangan di bawahnya dapat tercapai. Untuk itu, pemilihan material penutup atap dan konstruksi yang tepat menjadi penting dalam mengoptimalkan perannya dalam membendung dan mengangkut panas. Metode penelitian yang digunakan ialah kuantitatif. Hal ini karena dalam penelitian ini banyak melibatkan perhitungan kinerja atap terhadap nilai perpindahan panas, yaitu RTTV (Roof Thermal Transmittance Value), dan perhitungan radiasi. Bangunan yang distudi dipilih yang menggunakan atap dengan material yang berbeda, yaitu metal sheet tanpa insulasi, genteng keramik tanpa insulasi, dan genteng keramik yang dilengkapi insulasi. Hasil perhitungan RTTV menunjukkan bahwa atap yang paling memenuhi kriteria konservasi energi adalah atap genteng keramik yang menggunakan insulasi, dan yang paling boros energi adalah atap metal sheet tanpa insulasi

Authors: Murciano Hueso Alicia , Torrijos Fincias Patricia , Martín García Antonio Víctor
Published: July 2024

INTRODUCCIÓN. El concepto de tiempo es clave para entender la forma en que las personas envejecen, jugando un papel importante en la salud y en la percepción de bienestar de las personas mayores. MÉTODO. El propósito de esta investigación radica en estudiar las asociaciones entre la percepción del tiempo futuro, la edad y la satisfacción con la calidad de vida de los adultos mayores, tomando como factores moderadores los recursos individuales (condiciones de salud autoinformadas, capacidad cognitiva y funciones físicas). El diseño del estudio es de corte cuantitativo y de carácter no experimental (expost facto), a través de la técnica de cuestionario. La muestra quedó conformada por un total de 509 personas mayores de 60 años residentes en España. RESULTADOS. Los resultados revelan que la mayor parte de la muestra presenta una perspectiva del tiempo futuro extendido, percepción que se asocia a satisfacción vital incluso después de tener en cuenta recursos individuales como la salud autopercibida, y el funcionamiento físico y cognitivo. Además, a medida que aumenta la edad se presenta una perspectiva de tiempo más limitado asociada a una menor satisfacción vital; (c) los recursos individuales moderaron estas asociaciones, especialmente las condiciones de salud autoinformadas. DISCUSIÓN. Se entiende entonces que la forma en que perciben el tiempo futuro las personas mayores resulta ser un indicador de satisfacción con su calidad de vida y bienestar, independientemente de factores como la edad o los recursos individuales, lo que nos permite incidir en la importancia del tiempo subjetivo en relación con la adaptación satisfactoria en la vejez.

Published: July 2024

Las escuelas, como instituciones sociales, son lugares interesantes de conocer ya que poseen una cultura propia, compuesta de ritos complejos de relaciones personales, ética, tradiciones, costumbres y normas. El formador en este entorno tiene el rol de propiciar y asistir el avance del aprendiz en su proceso educativo, por medio de actividades y relaciones vinculantes, que buscan estimular el aprendizaje junto con desarrollar habilidades sociales, intelectuales y creativas durante la experiencia educativa, siendo interesante para comprender fenómenos propios desde el prisma de sus protagonistas, como las intersubjetividades entre formador y formados, la complejidad de las prácticas docentes, y los significados de estudiantes y docentes bajo rituales de la escuela. El presente articulo responde al objetivo de identificar la evidencia disponible en la investigación empírica de los últimos 5 años sobre el fenómeno de las Interacciones Educativas en contextos escolares y sus principales áreas de desarrollo. Se ha realizado un diseño de búsqueda sistemática por medio del protocolo PRISMA 2020. A partir de 20 artículos seleccionados, existen líneas temáticas centradas en las prácticas docentes, las TIC, la multiculturalidad y la educación inclusiva. Desde los hallazgos, se desprende que los fenómenos sociales emergentes a nivel sanitario, migratorio y tecnológico invitan a reflexionar a las comunidades académicas y educativas en torno a los procederes en que los actores educativos se relacionan en un proceso de construcción mutua, que incluyen las complejidades del constructo docente- estudiante, sus significados, creencias y ética en las diversas aristas en la cultura escolar.

Published: July 2024

Los motivos que llevan al alumnado universitario a desarrollar acciones de voluntariado son múltiples. Entre ellos, podemos encontrar la puesta en práctica de competencias de toda índole, la posibilidad de adquirir aprendizajes profesionales, la obtención de experiencia prelaboral y la mejora del currículum de cara a competir por un puesto de trabajo. El objetivo de la investigación se centra en analizar las motivaciones hacia la participación en voluntariado del estudiantado de Grado y Doble Grado (voluntario o no) de las cinco universidades presenciales de Valencia, observando, asimismo, las diferencias existentes en función del sexo, el curso y el área de conocimiento del alumnado. Para ello, se utilizó un diseño de investigación cuantitativo, aplicándose el Cuestionario de Motivaciones del Alumnado Universitario (CMV-AU) a una muestra de 1186 estudiantes (curso 2019/2020). Este cuestionario, adaptado y validado con dicha muestra, parte del Volunteer Function Inventory (VFI) de Clary et al. (1998). Los resultados evidencian que el estudiantado destaca las motivaciones relacionadas con la expresión de valores prosociales, la adquisición y puesta en práctica de habilidades y conocimientos, y la mejora del currículum. De igual forma, se observa que existen diferencias en el alumnado atendiendo a las variables analizadas. Estos resultados coinciden con los obtenidos en diversas investigaciones previas. Así, se concluye que el estudiantado universitario presenta mayor motivación de aprendizaje y mejora de currículum que otros colectivos, en especial las alumnas, el alumnado de los primeros cursos, y aquel matriculado en titulaciones de las áreas de Ciencias de la Salud y Ciencias Sociales y Jurídicas.

Published: July 2024

The present study investigated the relationship between strength capacity and motor performance in the gymnastic handstand. The hypothesis stipulated a positive relationship between motor performance and strength capacity levels. Thirty-two university students, 16 female and 16 male (24.03 ± 4.74 years of age,) participated in the study. The handstand was assessed using the absolute error of the three angles produced by the model (video) and the three angles produced by the performer. We conducted four strength tests: explosive force, maximum right-hand grip strength, maximum left-hand grip strength, and resistance force. The machine learning model was trained using 10 of the folds and cross-validated, and a linear regression test was performed using motor performance (absolute error) and strength tests (explosive force, maximum force right-hand, maximum force left-hand, and resistance force). The results showed that the machine learning model indicated a low relationship between strength capacity and motor performance. Additionally, motor performance was not found to be related to strength capacity. The results may indicate that specific capacities and the interaction of factors such as task specificity, environment, and individual characteristics influence motor performance.

Authors: Hes Bartłomiej Patryk , Nowacka- Chiari Ewa
Published: July 2024

Vital capacity (VC) tests are an important tool in assessing the functioning of the respiratory system. Low levels of vital capacity can indicate health problems such as asthma, chronic obstructive pulmonary disease, and other respiratory conditions. The volume of VC depends on many factors, especially the strength of the respiratory muscles, body and chest structure, lung and chest compliance, airway patency, gender, environmental factors, and physical activity. The aim of this study is to determine the level of vital capacity (VC) in girls and boys aged 10-13 who practice trampoline jumping, and to compare the results with reference values for a given gender and age category. The research was conducted among 100 trampoline jumpers (including 57 girls and 43 boys) aged 10-13. As part of the research, spirometric measurement was performed using the portable EasyOne model 2001 spirometer. The obtained results were then compared to reference values calculated on the basis of a study by the European Respiratory Society. The average level of vital capacity in the girls aged 10 was 2.2 liters, in 11-year-olds - 2.45 l, in 12-year-olds 2.54 l, and in 13-year-olds it was 3.02 l. The average level of vital capacity of the examined boys aged 10 was 2.36 l, in 11-year-olds 2.56 l, in 12-year-olds 2.89 l, and in 13-year-olds 3.33 l. These research results indicate that trampoline jumpers show a VC value within the reference values (between the LLN and ULN values). The girls stand out with higher percentage of predicted values for VC at the age of 11 (95.26%) and 13 (100.34%), in comparison with boys at the age of 10 (96.38%) and 12 (96.23%).

Causes and Consequences of Inefficient Drilling and Blasting in Mine Development Headings: A Case Study of Hard Rock Gold Mining Operations in Northern Tanzania
Authors: Bennett George
Published: June 2024

Despite the introduction of the perimeter blasting technique at the Tulawaka Gold Mine, the mine continued to suffer from an overbreak of mine development headings, with an average overbreak of 24% every 22 m, which is approximately twice the acceptable 10% overbreak. The causes of this problem include ineffective drilling practices and uneven and excessive charging of explosives, resulting in a slightly high powder factor of 3.94 kg/m 3 instead of 3.8 kg/m 3 , as per the design. The problem of overbreak resulted in ore dilution, a longer mine development cycle time and additional costs of approximately US$ 45 per cut, especially in mucking and hauling processes. This study proposed and recommended new drill and blast designs to solve this problem. Compared to the existing design, the proposed new drill design has a total of 12 fewer drill holes; this is a significant number of holes, which significantly reduces drilling costs. The proposed new blast design consumes approximately 25 kg less ANFO than the existing practice. Moreover, the study showed that large drives in the Star and Comet in the Geita Gold Mine suffer the most from the problem of ineffective advance per cut. One of the causes of ineffective advances per cut is the low amount of explosives used per cut compared to the planned amount.
APPLICATION OF A PROTECTIVE COATING BASED ON MAGNESIUM HYDROXIDE TO REDUCE OXIDATION OF THE SIDE SURFACE OF GRAPHITED ELECTRODES IN ARC STEEL-MELTING FURNACES
Authors: Гуляков В.С. , Вусихис А.С.
Published: June 2024

При выплавке стали в дуговых электропечах и ее внепечной обработке в агрегатах ковш-печь подвод электроэнергии для создания необходимой температуры осуществляется с помощью графитированных электродов, стоимость которых достаточно высока и оказывает заметное влияние на себестоимость продукта. Поэтому работа, направленная на снижение себестоимости стали путем снижения расхода графитированных электродов, для металлургов является актуальной. Расход графитированных электродов в значительной степени зависит от окисления их поверхности кислородом атмосферы печи. Результаты испытания показали, что покрытие на основе Mg(OН)2, нанесенное на поверхность образцов из графитированных электродов при температурах испытания в окислительной атмосфере, снижает на 30–40% убыль их массы. Защитные свойства испытуемого покрытия объясняются тем, что при попадании на поверхность графитированного электрода материал покрытия глубоко проникает в поры, закупоривает их и обволакивает поверхность. Под воздействием температуры вода испаряется, а покрытие, имеющее высокую адгезию, остается на поверхности. При температуре 350 °С Mg(OН)2 разлагается с образованием MgO с температурой плавления 2850 °С. Высокая плотность покрытия препятствует проникновению кислорода атмосферы к графиту электрода и снижает скорость его окисления.

When steel is smelted in electric arc furnaces and its out-of-furnace treatment in ladle-furnace units, power supply to create the required temperature is carried out by graphite electrodes, the cost of which is quite high and has a noticeable impact on the cost of production. Therefore, work aimed at reducing cost of steel by reducing the consumption of graphite electrodes is relevant for metallurgists. Consumption of graphitized electrodes depends to a large extent on oxidation of their surface by oxygen in the furnace atmosphere. The test results showed that the magnesium hydroxide-based coating applied to the graphite electrode surface reduced the weight loss by 30–40% at the test temperature in an oxidising atmosphere. With increasing temperature, the effect of mass loss increases. The protective properties of the tested coating are explained by the fact that it penetrates deep into the pores and envelopes the graphite electrode surface. Under the influence of temperature the water evaporates and the coating, which has high adhesion, remains on the surface. At 350 °C Mg(OH)2 decomposes to form MgO with a melting point of 2850 °C. The high coating density prevents atmospheric oxygen from penetrating the graphite electrode and reduces the oxidation rate.

В работе приводятся экспериментальные результаты исследования возникновения эмиссионного электрического тока в процессе химико-термической обработки и их теоретическое обоснование. Показано, что оксидные материалы, обладающие полупроводниковыми свойствами, наряду с металлами, формируют в технологических смесях электрические поля, участвующие в процессах переноса насыщающих элементов к упрочняемой поверхности детали из стали 35Х2Н3. Вклад этих полей в перенос насыщающих элементов сравним с вкладом концентрационных полей. Предложена конструкция и методика изготовления измерительной ячейки для определения величины эмиссионного тока, возникающего в технологической смеси. Получено уравнение, описывающее общий процесс твердофазного насыщения деталей с участием концентрационных и электрических полей при химико-термической обработке.

The paper presents experimental results of a study of the occurrence of emission electricity in the process of chemical-and-thermal treatment and their theoretical justification. It has been shown that oxide materials with semiconductor properties, along with metals, are capable of forming electric fields in technological mixtures that participate in the processes of transfer of saturating elements to the hardened surface of a part made of steel C0.35Cr2Ni3. The contribution of these fields is comparable to the contribution of the concentration field to the transfer of saturating elements. A design and manufacturing technique for a measuring cell are proposed to determine the magnitude of the emission current arising in the process mixture. An equation has been obtained that describes the general process of solid-phase saturation of parts with the participation of concentration and electric fields during chemical-and-thermal treatment.

В работе приведена новая технология обработки проволоки из нержавеющей стали. Данная технология заключается в применении криогенного охлаждения сразу после выхода проволоки из волоки. Результаты лабораторного эксперимента показывают, что применение криогенной деформационной обработки после волочения проволоки улучшает механические свойства по сравнению с традиционным волочением. Металлографический анализ доказывает, что условия деформации при криогенном волочении являются дополнительным фактором для реализации структурных ресурсов с целью оптимизации физико-механических свойств стальной проволоки.

This paper presents a new technology for stainless steel wire processing. This technology consists in the use of cryogenic cooling immediately after the wire leaves the drawing die. The results of the laboratory experiment show that the use of cryogenic processing after wire drawing improves mechanical properties compared to traditional drawing. Metallographic analysis proves that the deformation conditions during cryogenic drawing are an additional factor for the realization of structural resources to optimize the physical and mechanical properties of steel wire.

В данном исследовании на примере холоднокатаных листов было изучено раздельное влияние магния и цинка в количестве до 2% на структуру и механические свойства термически не упрочняемого термостойкого сплава Al–2%Cu–1,5%Mn, состав которого оптимизирован для получения максимальной доли фазы Al20Cu2Mn3. Установлено, что в литом состоянии цинк полностью находится в составе алюминиевого твердого раствора, магний частично входит в эвтектические частицы фазы Al2CuMg. Эти элементы практически не влияют на количество фазы Al20Cu2Mn3, которая формируется в процессе деформационно-термической обработки в виде наноразмерных дисперсоидов. Установлено, что добавление 1% магния повышает прочность холоднокатаных листов базового сплава на 15% после 3-ч отжига при 400 °С без снижения пластичности. Легирование цинком в свою очередь не оказывает существенного влияния на прочность.

In this study, using the example of cold-rolled sheets, the separate effect of magnesium and zinc in an amount of up to 2% on the structure and mechanical properties of a thermally non-hardening heat-resistant alloy Al–2%Cu–1.5%Mn, the composition of which is optimized to obtain the maximum fraction of the Al20Cu2Mn3 phase, was studied. It was found that in the cast state, zinc is completely contained in the aluminum solid solution, magnesium is partially included in the eutectic particles of the Al2CuMg phase. These elements practically do not affect the amount of the Al20Cu2Mn3 phase, which is formed during deformation and heat treatment in the form of nanoscale dispersoids. It was found that the addition of 1% magnesium increases the strength of cold-rolled sheets of the base alloy by 15% after 3-hour annealing at 400 °C, without reducing the plasticity. Zinc alloying, in turn, does not have a significant effect on strength.

Published: June 2024

Методом электроискрового легирования с использованием анодных сплавов на основе NiAl и Ni3Al получены покрытия, позволившие в условиях термоциклирования увеличить жаростойкость стали 30 до 10 раз и стали 20Х13 до 4 раз. Изучалась структура анодных сплавов и покрытий после термоциклирования с максимальной температурой нагрева 900 °С. Исследованием структуры поверхности образцов с покрытиями установлено преимущественное образование оксидов с высоким содержанием Fe (> 36 ат. %) в области ребер, тогда как на гранях формируются микротрещины, на поверхности некоторых обнаружены оксиды с высоким содержанием Fe (> 56 ат. %). Изучением структуры поперечных шлифов образцов с покрытиями показано, что покрытия состоят из двух слоев: нижнего, находящегося на границе с катодом, который содержит высокую концентрацию Fe (~ 80 ат.%) и верхнего. Верхний слой имеет состав, близкий к анодному сплаву, и в нем появляются поперечные микротрещины после термоциклирования. Установлено, что нижний слой покрытия играет роль барьера, препятствующего распространению микротрещин до поверхности катода. В местах, где нижний слой не является сплошным, микротрещины верхнего слоя распространяются до поверхности катода, что обусловливает формирование оксидов с высоким содержанием Fe на поверхности таких трещин.

Heat resistant coatings were obtained by electro-spark deposition method using anode alloys based on NiAl and Ni3Al, that can withstand thermal cycling conditions there by increasing heat resistance of mark AISI 1030 steel up to 10 times and of mark AISI 420 steel up to 4 times. The structure of anode alloys and coatings after thermal cycling at a maximal temperature of 900 °C was studied. When studying the surface structure of the samples with coatings it was established that oxides with high Fe content (> 36 at. %) were formed mainly on the ribs of the sample, whereas microcracks were formed on its sides and some of them having oxides with Fe content of high concentration (> 56 at. %). The study of structure of the transverse grinding samples with coating showed that the coating is composed of two layers: the lower layer, locating at the boundary with the cathode, having high concentration of Fe in its content (~ 80 at.%) and the upper one. The composition of the upper layer is close to that of the anode alloy, and transverse microcracks appeared in it after thermal cycling. It has been established that the lower layer of the coating acts as a barrier, preventing the microcracks to penetrate through the coating towards the cathode surface. In some places where the lower layer is not continuous, microcracks from the upper layer reach the surface of the cathode, and cause the exposure of oxides with high Fe content on the surface of such microcracks.

Published: June 2024

Food has become the solution for every living person, including plants and animals, to protect their health, sustain their lives and ensure their development. Consuming balanced and sufficient amounts of food is a necessity for the continuity of life. Therefore, all the processes of these food changes, starting from the lowest stage (agriculture, animal husbandry, fisheries), through activities such as production, execution and maintenance, to the final processes, constitute the food sector. The commercial value of this sector was 680 billion dollars in 1995 and 1.5 trillion dollars in 2018. Production and consumption play a big role in the fact that the volume of the food industry has more than doubled in a few years. The unification and easier expansion of a global transportation network has made a positive contribution to the food industry, as it does everywhere else. The purpose of this programming is to enable artificial intelligence to easily predict the annual sales amounts of a company that produces, supplies and sells bagels and the bagel demand for the next month. The research was carried out using the estimated artificial intelligence methods, LSTM (Long Short Term Memory) Neural Network and CNN (Convolutional Neural Network) Neural Network system. MSE (Mean Squared Error) and RMSE (Root Mean Square Error) were used to evaluate the accuracy of the prediction results. LSTM and CNN artificial intelligence methods have been tested in software and almost the same accuracy results are seen in both methods. Therefore, the change in the results of accurate estimation of the amount that can be sold will have a positive impact on profitability, competition with the market and sustainability.

Authors: Güzey Alparslan , Satman Mehmet Hakan
Published: June 2024

This study focuses on collaborative UAV/UGV routing problem in emergency logistics aiming to optimize the coordinated delivery efforts of both vehicles during disaster situations. By using a mixed integer model the study identifies the best delivery points and assigns specific drones to transport medical supplies to designated emergency assembly points. The research methodically assesses how UAV speed, UGV stops and cluster numbers affect delivery time. The results show that increasing UAV speeds and reducing stops and clusters generally lead to deliveries but achieving the time requires a careful balance due to their complex interactions. The study suggests that strategic coordination between UAVs and UGVs can significantly improve the efficiency of emergency logistics systems potentially reducing response times in disaster relief and medical supply deliveries. In conclusion the model highlights the potential for enhancements, in emergency response capabilities that could help save lives and lessen disaster impacts. Future studies should consider adapting the model for conditions and unpredictable scenarios to ensure resilience against demands.

In advanced Parkinson’s Disease (PD), and especially in PD related Dementia (PDD), psychotic symptoms are common. One of the manifestations of psychosis in PD is delusional misidentification syndrome, a phenomenon in which the patient believes the identity of a person, object or location has been duplicated or altered. Our patient, a 75-year-old female, was diagnosed with idiopathic Parkinson’s disease at the age of 68. Recently, her cognition deteriorated and she developed the believe that she lived in a replica of her real home. The delusion resolved completely with rivastigmine patches. Also visual hallucinations improved on treatment. This suggests that the dysfunctional connections were likely to be cholinergic.

Vibrio species are curved, motile, aerobic and facultative anaerobic, Gram-negative bacilli that are widely distributed in aquatic environments, especially marine and estuarine waters. Vibrios of primary concern in human pathology are essentially represented by the species Vibrio cholerae. Classification of Vibrio cholerae is based on the O-antigen polysaccharide type, with over 200 serogroups described. Historically, only toxigenic serogroups O1 and O139 have been associated with widespread cholera epidemics. Other serogroups can cause small outbreaks that spread via contaminated raw seafood (primarily shellfish and molluscs) and seawater exposure, and they are collectively termed Non-O1/Non-O139 Vibrio Cholerae (NOVC). NOVC, occasionally detected also in the Mediterranean Sea, most often causes sporadic gastrointestinal manifestations requiring supportive therapy. However, rarely the V. cholerae non-O1/ non-O139 serotype can result in extraintestinal manifestations such as severe wound infections, soft tissue infections and sepsis in immunocompromised patients that represent a therapeutic challenge. In particular, NOVC bacteraemia is a rare event but has the highest mortality rates among NOVC infections (almost 33%) and usually occurs in certain immunosuppressed populations, such as patients with haematologic and solid malignancies, and those with underlying liver disease.

Lipoblastoma is a relatively rare benign tumor. It derives from embryonic white fat cells. It almost exclusively affects children less than 3 years of age. We report a case of lipoblastoma of the left thigh detected in an older child (11 years) and a literature review. Diagnosis was based on histology while surgical treatment was based on total resection of the mass. The postoperative course was simple with a follow-up period of 9 months.

An 84-year-old male presented with right chest wall swelling for 4 weeks and a productive cough. There was no weight loss, fever or haemoptysis. On examination, right sided breath sounds were absent and soft tissue swelling was noted in the chest wall (Figure 1A). He was treated with right pneumonectomy in 1989 for a squamous cell carcinoma of the lung. Contrast CT chest revealed evidence of previous pneumonectomy, fluid in the right hemithorax with multiple fluid collections eroding to the chest wall with multiple rib erosions (Figure 2). Appearance was suspected of a tumour recurrence. USS guide fluid aspiration showed thick red cloudy fluid and was negative for malignant cells. He refused further intervention. His case was discussed in lung multi-disciplinary meeting and concluded to have a tumour recurrence. It was decided to manage him with best supportive care based on frailty and patient’s wishes. Lung cancer metastases in thorax has myriad of presentations and can be masquerading with a varied time gap from the original diagnosis. This include fistula formation, effusions, rib erosions, pulmonary deposits, lymphadenopathy, adjacent organ infiltration, superior vena cava and other vessel compression and thrombosis. Higher degree of suspicion is needed to avoid fatal outcome.

Routine use of IPC in the management of infection of the pleural space is contraindicated although there are challenging situations in which chest drains cannot be used due to number of reasons. A 63-year-old patient with a background of paranoid schizophrenia and severe learning disability with challenging behaviour presented with deterioration of mental health status for 2 days and chest discomfort and was managed as aspiration pneumonia. Her clinical condition deteriorated despite treatment and repeat CXR showed right sided effusion. Effusion was suspected to be pleural empyema and it was treated with chest drains. The patient pulled out three chest drains and it was challenging to retain the drain in situ to manage the empyema. There was concern of a trapped lung and pus was building up as the chest drains could not be maintained. A multi-disciplinary meeting was held, and it was decided to proceed with an Indwelling Pleural Catheter (IPC) with intermittent drainage, as keeping the IPC connected to water seal was not possible.

COVID-19 is known to induce clotting cascade abnormalities, posing challenges in managing warfarin for patients with thromboembolic conditions like atrial fibrillation and pulmonary embolism [1]. Some studies suggest a hypercoagulation state in COVID-19, potentially resulting in a reduced International Normalized Ratio (INR) for patients on warfarin [2]. However, the literature does not conclusively demonstrate a clear association between COVID-19 and fluctuations in the International Normalized Ratio (INR), particularly an increase in INR.

The article analyzes a clinical case of the development of thrombotic microangiopathy in a patient with ovarian cancer during chemotherapy, which manifested in the form of renal failure. An analysis of laboratory and biochemical findings is given, which were initially incorrectly interpreted and only a kidney biopsy made it possible to make a correct diagnosis and begin pathogenetic treatment. Cancer patients are at increased risk for developing secondary TMA, which requires increased attention to symptoms uncharacteristic of the underlying disease.
Research on China's Energy Financial Risk Early Warning and Internal Risk Control Spillover Characteristics
Authors: Binjie Lyu
Published: June 2024

It is of great significance to scientifically and effectively assess the spillover effects of internal and external risks in China's energy finance and build an accurate risk early warning system to steadily promote the realization of the " carbon peaking and carbon neutrality " goal. Multiple internal and external market data are selected, and the spillover index model based on quantile vector autoregression is used to capture the internal and external risk spillover characteristics under different market conditions and visualize them through complex networks. In addition, the early warning index of nonlinear Granger causal test is incorporated into the Attention-CNN-LSTM model to construct a risk early warning system. The empirical results show that: (1) There are significant risk spillover effects both inside and outside China's energy financial market under different market conditions, and the risk spillover index under extreme market conditions is greater than that based on conditional mean and conditional median. (2) The internal crude oil and fuel oil markets and the external energy and stock markets occupy an important position in the overall risk spillover system. (3) Comparing and analyzing the prediction effects of six different models, the MAE and RMSE of the Attention-CNN-LSTM model were 0.7686 and 0.9077, respectively, which were optimized by 12.9% and 21.4% respectively compared with the second-best performing CNN-LSTM model; Moreover, after adding the early warning indicators, the prediction effect of the Attention-CNN-LSTM model is improved by 19.8% and 31.9% respectively in MAE and RMSE compared with the original model, so it is more suitable for constructing China's energy financial risk early warning system.
Rationality in Medieval Literature – The Roots of Modernity in the Middle Ages?
Authors: Classen Albrecht
Published: June 2024

This study attempts to push the boundaries of our historical-intellectual concept regarding the origin and development of rationality as a modus vivendi not only since the eighteenth century, but already as an intellectual force in the Middle Ages, primarily reflected in literary works. While traditional courtly narratives reveal only tentative elements of rational thought patterns and forms of behavior, as soon as we turn to thirteenth-century romances and short verse mæren, do we recognize the emergence of rationality already in the pre-modern world. Rationality is here not identified as a comprehensive philosophical system pursued by the various poets; instead, it is perceived as a pragmatic approach to everyday situations in the lives of the various protagonists who commonly face dilemmatic situations and must apply ratiocination in order to come to terms with specific challenges, considering and balancing out contrastive options to limit harm to themselves and to make the best out of the conditions confronting them.
