Tubular turbines have been widely employed and evolved fast when its introduction in the 1930s due to their strong technical and economic qualities and application. Because its performance and structure differ from those of ordinary vertical shaft units, local and international academics worked extensively on research techniques and technological means using numerical simulation and model testing. The transmissions of a high quantity of power, which may cause unwanted vibrations that reduce efficiency, increase wear, and, in the worst-case scenario, cause serious damage. In this paper, the material propose in order to substantiate that the random excitations and excess vibration of the pico-turbine can be prevented is the use of CFRP (carbon fiber reinforced polymer) and PLA (polylactic acid). In this paper, ANSYS® Mechanical modal simulation is used to evaluate the structures’ robustness behavior of the composite materials that were used as the main material in the fabrication of turbine blades for bulb-type turbine application. The use CFD simulation in SOLIDWORKS® is needed to examine the pressure fluctuation caused by unsteady flow that can contribute in the unwanted pulsation and to conform the modal simulation results. To validate the results, pressure pulsation experimentation is conducted to evaluate the fluctuation of the pressure affecting the blades or in the rotating region and it is analyzed through frequency response domain. Hence, in this paper, it is proven that the vibration behavior of the material is acceptable since the resulting natural frequency provides resulting stress, strain, and deformation that is allowable and below its ultimate tensile strength.

Authors: Melekhov A. V. , Svetlakov V. I. , Bedritsky S. A. , Nikitin I. G.
Published: June 2024

Aim. To study the relationship between the probability and severity of dyspnea following COVID-19 pneumonia with the characteristics of lung ventilatory function (LVF), lung diffusion capacity (DCL), and respiratory muscle strength (RMS) impairments.

Materials and methods. A total of 108 patients (58% women, age 62 [52-66] years) who had recovered from COVID-19 pneumonia were examined. Spirometry, bodyplethysmography, DCL, and RMS assessments were conducted 75 (46-155) days after the onset of the disease. The severity of dyspnea was evaluated using the MRC (Medical Research Council Scale) and the 10-point Borg scale. Instrumental and laboratory data from the acute phase of COVID-19 were retrospectively obtained from medical records.

Results. The risk of dyspnea of any severity at the time of examination was statistically significantly higher in patients with reduced (z-score < -1.645) VC, FVC, FEV1, DLCO, VA, and DLCO/VA. No correlation was found between the risk of dyspnea and acute COVID-19 indicators (maximum C-reactive protein, lactate dehydrogenase levels, lung tissue damage assessed by computed tomography, positive PCR test), sex, or body mass index. None of the patients had a Gensler index <70%; however, reduced FEV1 was found in 10.3% of patients. Restrictive LVF impairments were observed in 8.3% of patients, and mixed impairments in 11.2%. Dyspnea severity was statistically significantly higher in patients with LVF impairments, especially with mixed type, compared to patients with normal respiratory biomechanics. The correlation between the risk of dyspnea and functional parameters persisted even when the sample was limited to patients with normal LVF (n=75) and without comorbidities (n=49). In patients with normal LVF and no comorbidities who did not report dyspnea, FEV1, ITGV, DLCO, and DLCO/VA values (in % of predicted) were higher, and Raw and Rocc were lower than in those with any severity of dyspnea.

Conclusion. There is a correlation between the risk and severity of dyspnea and restrictive, obstructive VFL impairments, and reduced DCL in the post-COVID-19 period. Additionally, identified patterns suggest that subclinical bronchial obstruction and reduced RMS may be possible mechanisms of dyspnea in patients with a normal respiratory biomechanics pattern.
ОККАЗИОНАЛИЗМЫ В СИСТЕМЕ НЕОЛОГИЗМОВ И ИХ ФУНКЦИИ В ХУДОЖЕСТВЕННОМ ТЕКСТЕ (НА МАТЕРИАЛЕ ПОЭЗИИ В. ХЛЕБНИКОВА)
Authors: Довлеткиреева Л.М. , Багаева З.А.
Published: June 2024

В статье рассматривается стилистическая функция окказионализмов в авторском тексте на примере поэтического наследия Велимира Хлебникова. Авторы определяют место окказиональных лексем в системе неологизации, приводят основные причины возникновения неологизмов и наиболее продуктивные словообразовательные модели, определяют различие между общеязыковыми и авторскими неологизмами, приводят классификацию окказионализмов, а также два взгляда на дефиницию термина «окказионализм» в современной неологии: 1. окказионализм – авторский неологизм, 2. окказионализм – разновидность авторских неологизмов, созданных с нарушением существующих словообразовательных моделей. Приводятся случаи, когда авторское слово перешло границы текста и стало «крылатым». Исследовав новообразования в поэзии одного из основоположников русского футуризма Велимира Хлебникова, авторы обосновывают научную позицию о том, что окказионализмы выполняют стилистическую функцию создания яркого, нетривиального, выразительного образа в тексте, поэтому они могут приравниваться к тропам. Особенность использования неологизмов в художественном стиле речи в том и заключается, что они не только обозначают некий предмет или реальность, но и выполняют функцию изобразительно-выразительных средств в созданном автором тексте. Отличаются от общеязыковых неологизмов еще и тем, что, в основном, создаются словообразовательными способами, не заимствуются, они характеризуют предмет более полно и точно. Еще одно отличие – живут в пределах созданного произведения, и потому долгие годы сохраняют оттенок новизны и оригинальности.

Factors Influencing Farmers’ Behavior Towards Modern Rice Varieties in Bangladesh
Authors: Islam Mohammad Samiul , Kamarulzaman Nitty Hirawaty , Shamsudin Mad Nasir , Mohd Nawi Nolila , Alam Mohammad Jahangir , Bhandari Humnath
Published: June 2024

The adoption of high-yielding agricultural technologies remains a promising strategy for achieving food security and poverty reduction in developing countries. With the innovation of green technology like seeds, fertilizers, and irrigation water, the productivity of land has increased significantly in Asian countries like Bangladesh. The high-yielding varieties of rice generate a yield gain of 15-20% over the conventionally bred varieties in general. Yet, despite strenuous government efforts, farmers’ adoption rates have remained low in Bangladesh compared to other Asian countries like India, China, and Vietnam. Therefore, this study was carried out to determine the factors influencing the adoption of modern high-yielding rice in some selected areas of the Mymensingh district in Bangladesh. A total of 510 smallholder rice farmers were randomly selected using a structured questionnaire. Descriptive analysis was used to evaluate the socio-demographic characteristics of farmers. The Tobit regression analysis was employed to figure out the factors influencing the adoption of modern rice cultivars. The results of the descriptive analysis showed that in the Boro season, about 64% of the area in the Mymensingh district was covered by modern high-yielding varieties. The outcome of Tobit regression indicated that variables such as farmers’ schooling, farm size, social membership, extension contract, training facilities, taste and preference, and yield capacity of new varieties were the significant and positive determinants to adopt modern rice cultivars, whereas farmers’ age, a distance of agricultural extension office, and fertilizer deficiency were significant but adversely associated with the adoption behaviour of the farmers. These findings recommended that rice breeders should emphasize the farmers’ preferences while developing varieties, as well as provide training, formal credit, trusted seed dealers, and membership access for spreading newly established HYV rice cultivars.
Forecasting the characteristics of the flood in 2024 on the Ishim, Tobol and Ural rivers
Authors:   Hydrometeorological Research Center of Russian Federation, Borsch S.V.
Published: June 2024

The Hydrometeorological Center of Russia has developed a system of methods for forecasting spring flood characteristics, which was implemented for eight stations on the Ishim, Tobol, and Ural rivers in 2024. Specific features of the methods are the simplicity of their obtaining and implementation for a particular river reach and a possibility of the fast correction of forecasts as the current information is available. The peak water level at the station was predicted based on its dependence on the peak water level at the upstream station. The date of the flood peak was predicted with account of the data of the peak at the upstream station and probable values of the travel time from the upstream gauge to the predicted downstream one. The date of the water level drop to the level of a severe event was forecasted taking into account the height and date of the flood peak using the calculated recession curve obtained by the statistical analysis of flood recessions in the previous years. The date of the water level drop to the level of an adverse event was predicted by extrapolating the flood recession observed during 10–15 days after the flood peak. The mean forecast lead time is 9 days. The forecasts were issued in a deterministic and probabilistic form and gave quite satisfactory results, which were used in the organization and implementation of measures to protect the population and economic facilities from the floods observed in 2024. The efficiency of the developed methods allows recommending them for use in predicting flood characteristics in various regions of Russia.

The study considers the reproduction of tides by two marine circulation models implemented for the Sea of Okhotsk: the z-model with a spatial resolution of ~3.7 km implemented directly for the Sea of Okhotsk, and the σ-model with a spatial resolution of ~3.5 km implemented for the Sea of Okhotsk and the Sea of Japan. The z-model is based on the HyRMoS (Hydrometcenter of Russia Model of Sea) model developed by S. K. Popov at the Hydrometeorological Center of Russia, the σ-model is based on the INMOM (Institute of Numerical Mathematics Ocean Model). The results of model simulations were compared with the data of harmonic constants of the main tidal harmonics presented at 98 coastal stations located in the Sea of Okhotsk and the Tatar Strait. An analysis of the calculation results showed that the accuracy scores are comparable for both models. The difference in the values of tidal harmonics revealed in the study and obtained from the z and σ models is primarily due to the accuracy and features of the bottom topography used and is also related to the location of the open boundaries and the configuration of the grid domains.

In today's world, businesses and individuals alike rely on cloud computing for storing and accessing data. However, with the growing number of cyber threats, it is crucial to prioritize cloud security. Despite various algorithms designed to prevent cyber-attacks, attackers have developed advanced tactics to bypass security measures. That's why it is essential to understand the three primary platforms of cloud computing and how they work together to create a seamless environment. Cloud cryptography is a highly effective method for encrypting data and enabling authorized users to access it securely. With the aid of an algorithm and a key, cryptography transforms plaintext into ciphertext, providing a defence mechanism against malicious third parties. The use of cryptographic methods ensures that only authorized entities can access the data exchange. Data encryption is a recognized and efficient security tool for safeguarding an organization's information. By converting data into a code that can only be accessed or interpreted by someone with the correct encryption key, data encryption provides a reliable defense against cyber threats. Cloud computing services, such as email, calendars, Skype, and WhatsApp, are becoming increasingly essential to our daily activities. These services allow us to store and manage data on the cloud infrastructure, enabling remote access to our data from anywhere at any time. Before cloud computing, accessing data relied on client-server computing. However, with cloud computing, we have access to a decentralized network of servers worldwide that work together to create a seamless environment. In conclusion, protecting data is crucial, and with the growing number of cyber threats, it is essential to prioritize cloud security. By implementing effective data encryption and cloud cryptography, individuals and organizations can safeguard their information and data from malicious attackers.
Making of a Nation
Authors: Desplanque Simon
Published: June 2024

La figure du président occupe une place à part aux Etats-Unis. Incarnation la plus visible de cette jeune nation, celui-ci a, dès les débuts d’Hollywood, été dépeint dans des fictions qui, chacune à leur manière, ont contribué à la propagation d’un certain imaginaire national tout en reflétant les préoccupations de leur époque. Le but de cet ouvrage est d’examiner de manière systématique la façon dont cette industrie s’est emparée de la figure et de l’héritage des présidents en poste entre 1945 et 1993. L’examen de ces représentations permet non seulement de mettre à jour les grandes dynamiques socio-politiques qui traversent les Etats-Unis depuis les années 1960 mais aussi, et peut-être surtout, de décortiquer quelques-uns des mythes sous-tendant l’imaginaire national qu’elles contribuent à édifier.

Authors: Nursasmi Ami Tri , Zelly Dia Rofinda  , Desywar
Published: June 2024

Background: Chronic hepatitis B (CHB) is a persistent hepatitis B virus (HBV) infection and can cause progressive liver damage. This damage can be measured through a decrease in albumin levels and an increase in liver enzymes such as aspartate aminotransferase (AST/SGOT), alanine aminotransferase (ALT/SGPT), and de Ritis ratio (AST/ALT). This study aims to analyze the relationship between albumin levels and SGOT, SGPT, and de Ritis ratio in CHB patients.
Methods: This cross-sectional retrospective analytical study involved 50 CHB patients diagnosed at Dr. M. Djamil General Hospital Padang between June 2022 to June 2023. Data on albumin levels, SGOT, SGPT, and de Ritis ratio were obtained from medical records. The de Ritis ratio, SGOT, and SGPT were grouped into normal and increased. Statistical analysis used an independent t-test with a significance of p < 0.05.
Results: The research subjects consisted of 26 men (52%) and 24 women (48%) with an average age of 42.46 ± 13.39 years. The mean albumin level in the increased SGOT group (3.69 ± 0.78 g/dL) was significantly lower than the normal SGOT group (4.39 ± 0.61 g/dL) (p = 0.003). The mean albumin level in the increased de Ritis ratio group (3.90 ± 0.80 g/dL) was also significantly lower than the normal de Ritis ratio group (4.46 ± 0.70 g/dL) (p = 0.006). There was no significant difference between albumin levels in the normal and increased SGPT groups (p = 0.548).
Conclusion: There is a significant negative relationship between albumin levels and SGOT and de Ritis ratio in CHB patients. Decreased albumin levels may be an indicator of more severe liver damage in these patients.

Formalin is used as a preservative in fish, as fish is a perishable product. The present study describes the development of a battery-operated portable colorimeter for the on-site determination of formalin in fish. Combining light sources of various wavelengths with an electric circuit and light dependent resistor results in a simple and cost-effective colorimeter. The gadget functions based on the light received by the light-dependent resistor, which is directly linked to the circuit board for resistance measurement using the resistance to absorbance connection and, the resistance values were converted to absorbance. The developed portable colorimeter is calibrated for the quantitative detection of formalin. The device exhibited an efficient detection of formalin at the range of 1 to 20 ppm. The portable colorimeter exhibited high accuracy and the results are promising for on-site detection of formalin in fish.

Authors: Cheng Chun-Yao , Hao Wen-Rui , Cheng Tzu-Hurng
Published: June 2024

In this editorial we comment on the article published in a recent issue of the World Journal of Gastroenterology . Acute liver failure (ALF) is a critical condition characterized by rapid hepatocellular injury and organ dysfunction, and it often necessitates liver transplant to ensure patient survival. Recent research has elucidated the involvement of distinct cell death pathways, namely ferroptosis and pyroptosis, in the pathogenesis of ALF. Ferroptosis is driven by iron-dependent lipid peroxidation, whereas pyroptosis is an inflammatory form of cell death; both pathways contribute to hepatocyte death and exacerbate tissue damage. This comprehensive review explores the interplay between ferroptosis and pyroptosis in ALF, highlighting the role of key regulators such as silent information regulator sirtuin 1. Insights from clinical and preclinical studies provide valuable perspectives on the dysregulation of cell death pathways in ALF and the therapeutic potential of targeting these pathways. Collaboration across multiple disciplines is essential for translating the experimental insights into effective treatments for this life-threatening condition.

Published: June 2024

a-Diazo carbonyl compounds are widely used as reagents of vast synthetic potential, capable delivering biologically relevant compounds and diverse molecular scaffolds. Herein we present methods for selective N-alkylation of various diazo NH-heterocycles while maintaining the diazo function for further modifications. a-Diazo homophthalimide, diazo arylidene succinimides, diazo barbituric and thiobarbituric acids, and a-diazo pyrazolones were readily alkylated with alkyl halides or alcohols under Mitsunobu reaction conditions. This is the first time that the Mitsunobu reaction has been applied for the functionalization of diazo carbonyl compounds. The method expands the scope of substituents that can be introduced into the diazo molecule, including such challenging moieties as adamantyl, cholesteryl and menthyl.

Los perros cuentan con una audición superior a la humana, esto respecto al espectro de frecuencias que su sistema auditivo les permite percibir, por lo tanto, detectan sonidos que son imperceptibles para el oído humano y reaccionan de diferente manera a ruidos con altas frecuencias. Las personas que poseen perros son conscientes del daño que la exposición a ruidos fuertes provoca en sus mascotas, principalmente el estrés que ruidos como la detonación de fuegos artificiales les provoca. En la búsqueda de un método para contrarrestar los efectos del estrés provocados por ambientes ruidosos, surge la propuesta de emitir ruido blanco.  El ruido blanco ha demostrado tener efectos relajantes tanto en humanos como en animales por lo que se presenta la idea de desarrollar un dispositivo capaz de emitir ruido blanco para mantener tranquilos a perros domésticos durante eventos estresantes, el dispositivo consta de un diseño auricular y un control por medio de un servidor web, que permite a los dueños manipular las características del ruido a generar por los auriculares.

Lecturers play a crucial role in the educational process, offering unique insights and perspectives within the classroom. The issue of cred­ibility in educational assessment often rests on the shoulders of lecturers, who are responsible for eval­uating students' progress. The present study aimed to investigate lecturers' attitudes and perceptions re­garding the potential of ChatGPT for instructional assessment. A correlational research design was adopted, and purposive sampling was used to select 102 lecturers from Nigerian universities who had uti­lised ChatGPT for instructional assessment. Data was collected through an online structured question­naire. The normality and homogeneity of variance assumptions were met, as evidenced by kurtosis and skewness values falling within acceptable thresh­olds. The lecturers employed the instructional assessment questionnaire utilising ChatGPT to gather and analyse the data, employing t-tests and ANOVA. The findings revealed a statistically significant difference between perception (F (3, 98) =7.168, p=0.001 <0.05) and lecturers' years of experience in using ChatGPT for instructional assessment. The study indicated that lecturers held low attitudes and had poor perception levels when it came to exploring the potential of ChatGPT. However, it is recommended that training be provided to enhance lecturers' attitudes and perception levels to fully exploit the potential of ChatGPT for instructional assessment.

Authors: Boateng Sakyiwaa , Maroloma Simthembile
Published: June 2024

This study examines how physical sciences teachers in South African high schools perceive the use of practical work in chemistry instruction. The study is grounded in the framework of social constructivism. Qualitative research methods, including semi-structured interviews and classroom observations, were employed to gather insights from a purposively selected sample of four high school chemistry teachers, each from a different high school. The aim was to explore their perspectives on the incorporation of practical work in chemistry teaching. Thematic analysis of the data revealed a range of insights into teachers' perceptions. The findings indicate that teachers recognise the value of practical work in engaging students and reinforcing theoretical knowledge. However, they also face several challenges that hinder its effective implementation, such as inadequate laboratory facilities, limited access to resources, time constraints, and insufficient teacher training. Despite these obstacles, teachers demonstrate a strong commitment to integrating practical work into their teaching and employ innovative strategies to overcome these barriers. They highlight the need for increased support from educational authorities in terms of resource provision, professional development opportunities, and curriculum alignment. The study provides recommendations for educational policymakers, curriculum developers, and teacher training institutions to address these perceived challenges and enhance the quality of chemistry teaching and learning in South African high schools.

The article highlights Russian historical experience in procurement and procurement of food, ranging from surplus appropriation, tax in kind, NEP to the organization of an extensive state system. Procurement mechanisms have been identified, which are currently carried out on a competitive basis and are centralized. It is shown that the production of the required volumes of food to be purchased is ensured by commodity producers through the effective use of production factors. These include: land, labor, capital, entrepreneurship, information, and the ecological environment. Conclusions are drawn about the specifics and need to improve the public procurement system in the context of the increasing policy of sanctions from Western countries and the United States, and current directions for the development of this system are proposed.

The Parker Solar Probe's discovery that magnetic switchbacks and velocity spikes in the young solar wind are abundant has prompted intensive research into their origin(s) and formation mechanism(s) in the solar atmosphere. Recent studies, based on in situ measurements and numerical simulations, argue that velocity spikes are produced through interchange magnetic reconnection. Our work studies the relationship between interplanetary velocity spikes and coronal brightenings induced by changes in the photospheric magnetic field. Our analysis focuses on the characteristic periodicities of velocity spikes detected by the Proton Alpha Sensor on the Solar Orbiter during its fifth perihelion pass. Throughout the time period analyzed here, we estimate their origin along the boundary of a coronal hole. Around the boundary region, we identify periodic variations in coronal brightening activity observed by the Atmospheric Imaging Assembly onboard the Solar Dynamics Observatory. The spectral characteristics of the time series of in situ velocity spikes, remote coronal brightenings, and remote photospheric magnetic flux exhibit correspondence in their periodicities. Therefore, we suggest that the localized small-scale magnetic flux within coronal holes fuels a magnetic reconnection process that can be observed as slight brightness augmentations and outward fluctuations or jets. These dynamic elements may act as mediators, bonding magnetic reconnection with the genesis of velocity spikes and magnetic switchbacks.
