Published: April 2024

The independent campus learning curriculum currently being developed focuses on student-centered learning so that lecturers are not the only source of learning. This research was motivated by the lack of student learning independence and low learning outcomes in craft arts learning. The aim of the research is to produce Digital Student Worksheets that are feasible and effective in increasing student learning independence in Arts and Crafts courses in the Fashion Design Education study program. This development research uses the Thiagarajan 4-D development model. This model consists of 4 stages, including the needs analysis stage, product design stage, validation and evaluation stage. The results of validation by material experts obtained an average result of 4.12 in the feasible category. the validation results from media experts obtained an average score of 4.27 in the adequate category. The results of trials carried out by lecturers and students obtained an average score of 4.55 in the very good category. At this stage, an evaluation of all activities that have been carried out is carried out, especially the input provided by experts and users. The results of the posttest carried out obtained an increase of 28% in improving learning outcomes. Digital LKM is suitable for use in learning and motivates students to increase student independence. Digital LKM can help students learn independently. The implication of this research is that digital LKM can be used by teachers because it can present problems in more detail so that students can construct their knowledge independently.
A Second-Order Mach-Uniform Scheme for the Unsteady Compressible Navier-Stokes Equations on Orthogonal Unstructured Grids
Authors:   , Jones David
Published: April 2024

The disparity in the physics of high speed and low speed fluid flows has lead to the development of computational fluid dynamics methods for these flow conditions traditionally being considered separately. As a result there are many well-developed, efficient, and accurate schemes available that perform well in one case, but not the other. Nonetheless, there are many flow cases of engineering interest that contain both types of flow within the same domain. Examples include rotorcraft in hover, gas turbines at start-up, and propellers at take-off. There is therefore a need for a solver that performs well across a wide range of Mach numbers.The development of a solver that remains efficient and accurate for flows for all speeds up to the high supersonic range is presented and discussed. The solver uses a staggered, segregated pressure correction approach, characteristic of low speed solvers. The pressure is corrected so as to enforce conservation of energy, providing strong coupling between the pressure and other flow variables at low speeds without losing efficiency at high speeds.The modification of an existing two-dimensional Mach-uniform inviscid solver is first discussed and extensively validated. Then, the extension of the solver to viscous flow is considered. Finally the solver is extended to the case of unsteady flows with moving boundaries, which is achieved through the use of the Chimera method. The solver is shown to be efficient at all speeds in all three cases, and grid refinement studies are performed which demonstrate the second-order spatial accuracy of the solver. Additionally, a time step refinement study is performed for the unsteady solver, confirming that it achieves second-order temporal accuracy.Recent advances in the generation and optimisation of unstructured grids have pro-vided good quality orthogonal grids even for relatively complex geometries. The solver makes use of grids produced using these methods, resulting in a pressure correction that is both simple and robust.
Development of Spectral Signature of Chir Pine Using Hyperion Data
Authors: Langlentombi L. Chanu
Published: April 2024

The study was conducted during January, 2023 which aims to map the chir pine forest of the Almora region of Uttarakhand, India using hyperion data and construct a spectral signature. The data was processed using ENVI 4.4 software. For image classification, the Spectral Angle Mapper (SAM) was employed. Many remote sensing projects covering relatively large areas have effectively exploited multispectral data for data extraction and statistical analysis of natural resources. Hyperspectral imagery has seen recent methodological and technological developments that open up new avenues for researching the structure and processes of local ecosystems. Within the realm of sustainability studies, trees are deemed essential for a multitude of ecosystem services that encompass environmental quality, food security, and human health. Species level tree mapping could be one of these prerequisites. Using a reliable method for species-level remote sensing of forest composition will significantly advance our understanding of these dynamics. After the correct match between field spectra and pixel spectra was established, the spectra library of chir pine was created. The result show that the NIR spectral range (700–1300 nm) has higher spectral reflectance than the visible region (400–700 nm). The data indicated a sharp decrease shortly after 1300 and 1700 nm. The library of spectral signature created for the chir pine will serve as the target spectrum for the classification of remote sensing data pertaining to this species. With this knowledge, there may be considerable opportunity to support upcoming initiatives aimed at sustainability in various socio-ecological contexts.

Published: April 2024

Aim. Development of a method of analytical research of a two-mass oscillating system with parallel elastic and damping elements, which makes it possible to expand the design of such systems in various tasks of the functioning of machines and equipment. Method. We will conduct a parametric study of the dynamic oscillation system to assess the effect of the elasticity coefficient and damping on the change in the natural frequency, using the Laplace transform method. A mathematical model of the system with two masses connected by elastic and damping elements placed in parallel is presented. Disturbances are transmitted to the masses through an elastic-damping system. Results. The solution of the system of differential equations through the Laplace transform for two variants of the characteristic equation is given. The biquadratic characteristic equation is solved by the Ferrari method. Both for the roots with complex numbers and for the roots with real numbers, the values of the roots λ1 ... λi are obtained. The value of the roots of the biquadratic equation for the general solution of a homogeneous system of differential equations enables stability for the values of the six roots of the characteristic equation. Unlike previous studies, where applied disturbances were described in the form of harmonic oscillations, we proposed a solution for disturbances in the form of discrete single pulses of different durations and different tracking frequencies, from one pulse to n pulses. Scientific novelty. The analytical solution of the system of differential equations that describe the mutual oscillation of masses connected in parallel by elastic and viscous elements refers to a subspecies of the classical Kelvin-Voigt body. In comparison with other mathematical models, the analytical solution of the system of differential equations describing the movement of the masses of the system will allow to study the system with structural parameters in a wide numerical range of their numerical values. Practical value. The analytical model allows modeling technical systems that work according to this principle. For example, suspensions of cars and other vehicles for various purposes. The mathematical model is analytically solved and allows to optimize suspension designs

Published: April 2024

In this study, 200 Norwegian dairy farms were analyzed over three years to compare greenhouse gas emissions, nitrogen (N) intensity, gross margin, and land use occupation between organically and conventionally managed farms. Conventionally managed farm groups were constructed based on propensity matching, selecting the closest counterparts to organically managed farms (n=15). These groups, each containing 15 farms, were differentiated by an increasing number of matching variables. The first group was matched based on geographical location, milk quota, and milking cow units. In the second match, the proportion of milking cows in the total cattle herd was added, and in the third, the ratio of milk delivered to milk produced and concentrate usage per dairy cow were included. The analysis showed that the conventionally managed farms (n=185) had higher greenhouse gas emissions (1.42 vs 0.98 kg CO2 per 2.78 MJ of edible energy from milk and meat, calculated as GWP100-AR4) and higher N intensity (6.9 vs 5.0 kg N input per kg N output) compared to the organic farms (N=15). When comparing emissions per kg of energy-corrected milk (ECM) delivered, conventional farms also emitted more CO2 (1.07 vs 0.8 kg CO2 per kg ECM). Furthermore, conventionally managed farms showed lower gross margins both in terms of NOK per 2.78 MJ edible energy delivered (5.8 vs 6.5 NOK) and per milking cow unit (30 100 vs 34 400 NOK), and they used less land (2.9 vs 3.6 m² per 2.78 MJ edible energy delivered) compared to organic farms. No differences were observed among the three conventionally managed groups in terms of emissions, N intensity, land use occupation, and gross margin.

This is my first attempt to communicate with the ChatGPT on the cosmic microwave background (CMB). ChatGPT reviewed the history of the CMB discovery and its development, reacted with a list of important scholars in this field of research, and presented a list of the most stimulating papers from the history of this research. ChatGPT mentioned also a list of scholars who have been working on some alternative interpretations of the CMB together with references to papers not so often cited. ChatGPT gave some proposals for future research in this field and mentioned also some potential possibilities to work with alternative models. However, in order to appear with an alternative scenario, it is very important to explain existing knowledge about the CMB and moreover to propose new tests in order to penetrate deeper into the core of this effect. This conversation could be a quick start up in this field for newcomers.

Published: April 2024

Repositioning is all nursing activities that aim to change the posture of bedridden patients from one side to another during the hospital stay to minimize the pressure load on bony prominences and prevent pressure ulcers or injuries from developing. This is a discussion paper based on nursing and healthcare quality literature references. This paper describes the importance of repositioning practice based on the empirical study and experience as nurses and nurse managers. This perspective supports the existing literature to link repositioning practice and the quality of nursing care process indicators. Repositioning practice could be considered as an indicator of the process of care. This paper emphasizes repositioning practice as a fundamental nursing intervention and how it becomes meaningful for nursing indicators. Nurses need a standard of repositioning and its measurement at the international level.

Pathogenesis and potential reversibility of intestinal metaplasia − a milestone in gastric carcinogenesis
Authors: Drnovsek Jan , Homan Matjaz , Zidar Nina , Smid Lojze M
Published: April 2024

Background

Non-cardia gastric cancer remains a major cause of cancer-related mortality worldwide, despite declining incidence rates in many industrialized countries. The development of intestinal-type gastric cancer occurs through a multistep process in which normal mucosa is sequentially transformed into hyperproliferative epithelium, followed by metaplastic processes leading to carcinogenesis. Chronic infection with Helicobacter pylori is the primary etiological agent that causes chronic inflammation of the gastric mucosa, induces atrophic gastritis, and can lead to intestinal metaplasia and dysplasia. Both intestinal metaplasia and dysplasia are precancerous lesions, in which gastric cancer is more likely to occur. Atrophic gastritis often improves after eradication of Helicobacter pylori; however, the occurrence of intestinal metaplasia has been traditionally regarded as “the point of no return” in the carcinogenesis sequence. Helicobacter pylori eradication heals non-atrophic chronic gastritis, may lead to regression of atrophic gastritis, and reduces the risk of gastric cancer in patients with these conditions. In this article, we discuss the pathogenesis, epigenomics, and reversibility of intestinal metaplasia and briefly touch upon potential treatment strategy.

Conclusions

Gastric intestinal metaplasia no longer appears to be an irreversible precancerous lesion. However, there are still many controversies regarding the improvement of intestinal metaplasia after Helicobacter pylori eradication.

Published: April 2024

Introduction:

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection represented a disruptive pathology that emerged in late 2019 with profound implications ranging from individual health to health systems and world economy. Our study aimed to evaluate clinical, biochemical and computerized tomography (CT) parameters values in determining the severity of pulmonary embolism (PE) associated with COVID-19.

Methods

We performed an observational cohort study evaluating demographic, clinical, biochemical, coagulation markers, as well as CT imaging parameters.

Results

In our study on 186 patients with COVID-19, we found that 31 patients (16,66%) had pulmonary embolism. Significant correlations for the patients with PE were detected in C-reactive protein, lactate dehydrogenase, serum ferritin, IL-6, serum myoglobin, NT-proBNP, D-dimers, serum proteins, transaminases as well as white cell blood counts. Patients with pulmonary embolism had a more severe lung involvement, with thrombi distribution mainly involving the lower lobes.

Conclusion

Early identification of PE is an important step for timely and efficient treatment in the intensive care management of COVID-19 patients. Our study showed that high plasmatic values of lactate dehydrogenase, ferritin, IL-6, white blood cells and D-dimers and low proteins serum levels are strongly linked with COVID-19-associated pulmonary embolism.
Development of Wetting-Drying Curves from Elastic Wave Velocities Using a Novel Triaxial Test Apparatus

Published: April 2024

The relationship between the soil water characteristic curve (SWCC) and the mechanical behavior of unsaturated soil is imperative and has been well investigated. However, the correlation between elastic wave velocity along the wetting and drying paths of SWCC is largely unknown due to the nonavailability of a standard experimental setup for such a purpose. An ordinary triaxial apparatus has been modified for laboratory assessment of SWCCs under different Ko stresses, along with the measurement of shear and compression wave velocities in due course. The main aim of the study is to draw SWCC, wave velocity characteristic curve (WVCC), and a Poisson’s ratio characteristic curve (PRCC) and to establish the phenomenon that these curves possess hysteresis. The Poisson’s ratio was obtained indirectly by measuring Vp and Vs. Three soil samples with relative densities of 85%, 56%, and 39% were prepared and placed in a modified triaxial test apparatus under wetting and drying cycles. The test results showed that the newly developed apparatus is accurately capable of measuring SWCC. Owing to the similarity in the shape of wave velocity and Poisson’s ratio, response to SWCC, WVCC, and PRCC are drawn. The phenomenon of stress history and the effective stress of the soil affected the behavior during wetting and drying paths.
Ohne Fleiß kein Preis – die deutsche Volkswirtschaft muss sich ihre Innovationsfähigkeit immer wieder neu erarbeiten
Authors: Schmidt Christoph M.
Published: April 2024

The medium-term prospects for the German economy give little cause for optimism. In addition, demographic change will intensify in the current decade. A brightening of growth prospects can therefore only materialise with stronger investment and greater innovation momentum. However, it will hardly be enough to directly promote this through economic policy interventions if the available pool of adaptable and skilled labour cannot be strengthened. This will require a wide range of economic policy endeavours.
Deutsche Wirtschaft kränkelt – Reform der Schuldenbremse kein Allheilmittel
Authors: Bönke Timm , Holtemöller Oliver , Kooths Stefan , Schmidt Torsten , Wollmershäuser Timo
Published: April 2024

Cyclical and structural factors are overlapping in Germany’s sluggish overall economic development. Until recently, there have been more headwinds than tailwinds from both the external and domestic economy. A low momentum recovery is likely to set in after spring. Net immigration has stabilised the labour force substantially; the productivity of immigrants remains subdued though due to integration problems and qualification mismatches. While a mild reform of the debt brake is advisable, a reorganisation of the overall fiscal constitution to better shield municipal investment activity from cyclical budget shortfalls is much more important.

Assessment of the level of knowledge and awareness of abdominal hernia as a risk factor for acute intestinal obstruction among the adults of Saudi Arabia
Authors: Alkhudhayri Abdulaziz , Alorini Rasha , Alsury Leena , Alhawiti Meshari , AlGadaa Ayman
Published: April 2024

Background: Abdominal hernia occurs when tissues protrude through the abdominal walls with symptoms such as pain, inflammation, tenderness, and vomiting. It is thought that abdominal hernias pose a risk factor for the development of acute abdominal obstruction in patients who seek emergency care for abdominal discomfort because they cause bowel obstruction when they occur.
Methods: The study adopted descriptive a cross-sectional design from a sample of 533 participants in the Saudi Arabian general population. Data were analyzed using Statistical Package of Social Sciences Version 27.
Results: The findings revealed that 30 (5.6%) of the participants had an abdominal hernia. 17 (3.2%) of them had an acute intestinal obstruction. A considerable proportion 249 (46.7%) of the participants indicated that they had weak knowledge about abdominal hernia. The study results revealed a poor knowledge level about abdominal hernia as a risk factor for acute abdominal obstruction in 346 (64.8%) of the participants with only 187 (35.2%) of them exhibiting good knowledge. The knowledge of abdominal hernia as a risk factor for acute abdominal obstruction was found to be significantly associated with age, education level, and work status (p-values< 0.05)
Conclusion: The study results revealed a considerably poor knowledge level about abdominal hernia as a risk factor for acute abdominal obstruction among the general population in Saudi Arabia. Participants who were 30 years of age or older, those who had attained a higher level of education, and those employed were associated with better knowledge of abdominal hernias. There is a need for public awareness about abdominal hernia among the Saudi Arabian populace.
The identity $7^{3n}+7^{3n+1}=(2\cdot 7^n)^3$ and its generalizations
Authors: Gryszka Karol
Published: April 2024

Starting with the identity $7^{3n}+7^{3n+1}=(2\cdot 7^n)^3$ and its sibling, we prove that for any positive integer $m$, the diophantine equation $x^n+x^{n+k}=z^m$ has infinitely many solutions in nonzero integers $x$, $z$, $n$ and $k$. We show that in case $k>1$ the solutions come from the Catalan's Conjecture. We also solve three similar diophantine equations.

Liczba pi – perła w koronie Królowej nauk
Authors: Koroński Jan
Published: April 2024

W artykule znajdziemy pewne refleksje nad tym czym jest matematyka, jaka jest jej istota i znaczenie. Wymieniamy kilka podstawowych stałych matematycznych, wśród których najważniejszą wydaje się byćliczba π. Dalej podajemy pewne bardziej szczegółowe informacje historyczne o przybliżeniach liczby π i o wybranych wzorach (rozwinięciach w iloczyny i szeregi nieskończone) na liczbę π. Wspominamy również o niewymierności i przestępności liczby π nawiązując do tzw. problemów starożytnych. W dalszym ciągu zwracamy uwagę na znaczenie liczby π w kontekście hipotezy Riemanna i stałej struktury subtelnej, a także kilku innych fundamentalnych stałych fizycznych definiujących stałą struktury subtelnej. Na koniec formułujemy nowe wyrażenie liczby π poprzez podstawowe stałe fizyczne.

Iraq’s Human Security and the Challenges of the Rapid Population Growth
Authors: م.م فيصل عبد اللطيف ياسين
Published: April 2024

Abstract

Iraq is going through a rapid population growth resulting from high birthrate and fertility compared to regional and international rates. Iraq’s annual population growth is estimated at 2.55, while the country’s fertility stands roughly at 3.5 births per woman. It is projected that Iraq’s population will reach around 50 million by 2030. This increase in Iraq’s population, especially when the majority of Iraq’s population is youth, has perilous impacts on Iraq’s human security. Challenges emanating from population growth and demographic transformation overlap and feed into an array of economic, social, security, and environmental problems that Iraq is already facing. Iraq’s economy which relies almost entirely on oil revenues is not capable of creating enough job opportunities to accommodate the increasing number of Iraq’s labour force. Also, the growing population is putting immense pressure on the country’s debilitated infrastructure and limited public services. Population growth puts pressure on the authorities to keep up with the people needs of millions of citizens for housing, health, and education. Population growth is straining Iraq’s natural resources when climate change and water scarcity are causing drought, destruction of arable land and demise of food crops. Finally, the loss of prospects for the future and lack of job opportunities are driving Iraqi youth to either migrate or resort to violence and organized crime.
Automatic classification of emotions in speech: methods and data
Authors: Lemaev Vladislav Igorevich , Lukashevich Natal'ya Valentinovna
Published: April 2024

The subject of this study is the data and methods used in the task of automatic recognition of emotions in spoken speech. This task has gained great popularity recently, primarily due to the emergence of large datasets of labeled data and the development of machine learning models. The classification of speech utterances is usually based on 6 archetypal emotions: anger, fear, surprise, joy, disgust and sadness. Most modern classification methods are based on machine learning and transformer models using a self-learning approach, in particular, models such as Wav2vec 2.0, HuBERT and WavLM, which are considered in this paper. English and Russian datasets of emotional speech, in particular, the datasets Dusha and RESD, are analyzed as data. As a method, an experiment was conducted in the form of comparing the results of Wav2vec 2.0, HuBERT and WavLM models applied to the relatively recently collected Russian datasets of emotional speech Dusha and RESD. The main purpose of the work is to analyze the availability and applicability of available data and approaches to recognizing emotions in speech for the Russian language, for which relatively little research has been conducted up to this point. The best result was demonstrated by the WavLM model on the Dusha dataset - 0.8782 dataset according to the Accuracy metric. The WavLM model also received the best result on the RESD dataset, while preliminary training was conducted for it on the Dusha - 0.81 dataset using the Accuracy metric. High classification results, primarily due to the quality and size of the collected Dusha dataset, indicate the prospects for further development of this area for the Russian language.

This study explores the conceptual gap regarding patience between Western psychology and Islam, and aims to identify the factors that influence patience in the context of Islamic psychology. Academic hardiness, self-control, resilience, grit, and self-acceptance influence the level of patience in the context of Islamic psychology are the hypotheses. This study employs a quantitative research design involving 213 Muslim students from the Universitas Islam Riau. Data collection was carried out using Patience in Islamic Psychology Scale, Oviedo Grit Scale, Revised Academic Hardiness Scale, Self Control Scale, Adolescent Resilience Scale and Berger's Self-Acceptance Scale. Data analyzed using the SmartPLS 3.0 M3 program. The results of the study indicate that academic hardiness, self-control, resilience, and self-acceptance significantly affect the level of patience in the context of Islamic psychology. Interestingly, the findings reveal that grit has a significant negative impact on patience in Islamic Psychology. Success in the theory of grit (Western psychology ) is defined as achieving desired goals, while success in Islamic psychology is defined as striving within the permissible boundaries. However, in the event of failure, it is important not to lose hope and to remember the blessings bestowed by Allah that have been received.
