Background: In low- and middle-income countries (LMIC), 45% of deaths could be addressed by implementation of an emergency medical services (EMS) system. Prehospital care is a critical component of EMS worldwide, and basic, affordable training has been shown to improve EMS systems. However, patient outcome impact is unclear. In this study we aimed to assess the current state of prehospital care in Kigali, Rwanda, through a needs assessment, focused training intervention, and analysis of current practices and patient outcomes. Methods: We identiﬁed 30 clinicians through the prehospital medical command ofﬁce and included them in the study. A prospective, nonrandomized, interrupted time-series approach was used. Data collected through closed- and open-ended questionnaires included age, sex, training, and knowledge assessment. We used the data to create a tailored, 18-hour training after which immediate and 11-month post-tests were administered. Linked prehospital and hospital care datasets allowed for evaluation of patient outcomes and prehospital process indicators that included training skill application, airway intervention, intravenous ﬂuid administration, and glucose administration. Results: Of 30 clinicians, 18 (60%) were female, 19 were nurses, and 11 were nurse anaesthetists. Median age was 36, and median years providing care was 10 (IQR 7–11). Twenty-four (80%) participants completed immediate and post-test assessments. Mean knowledge across 12 core skills signiﬁcantly improved from a pre-test mean of 59.7% (95% conﬁdence interval [CI] 42.2–77.20) to a post-test mean of 87.8% (95% CI 74.7–100). At 11 months post-training, the score improvement maintained, with a mean score of 77.6%(95% CI 59.2–96.8). For patient outcomes, the total sample size was 572 patients; 324 of these patients were transported to the ED during the pre-training period (56.4%), while 248 were transported post-training. Prehospital oxygen administration for patients with a saturation level of <95% signiﬁcantly increased pre- to post-training (66.7% to 71.7%; Δ = 5.0%; Δ95% CI 1.9,−8.1%). No signiﬁcant changes were noted in patient treatment outcomes or other process indicators due to small sample sizes. Conclusion: This study provides insights on Rwandan EMS and demonstrates that a tailored intervention targeting education on prehospital process indicators has positive impacts on clinician knowledge and practice.

Authors: Nourollahi-Darabad Maryam , Afshari Davood , Karimi Noorollah , Seyedtabib Maryam
Published: November 2024

Background: Physical and mental workload (MWL) are very important factors that affect patient safety and the quality of nursing services. Psychosocial risk factors in the workplace are among the most important factors that threaten nurses’ MWL. Objectives: The study was carried out to examine MWL and predict the psychosocial and demographic factors that affect the MWL of nurses, based on the structural equation model (SEM). Methods: This cross-sectional descriptive-analytical study was conducted in 2021. Participants were 234 nurses from a teaching hospital in Ilam, Iran. General Health Questionnaire-12 (GHQ-12), the NASA-TLX Questionnaire, Copenhagen Psychosocial Questionnaire (COPSOQ), and a demographic questionnaire were used. The overall relationship between the variables was analyzed using the SEM. LISREL 8.8 software was used in the study to estimate the model and test the fit of the model. Results: Based on the NASA-TLX Index, the overall MWL score was 70.09 ± 9.51. Examining the MWL subscales showed that the mean effort score (71.41 ± 8.93), frustration (71.38 ± 5.50), and physical demand (70.74 ± 7.00) were higher than other dimensions of MWL. In the presented SEM, there was a significant relationship between individual and psychosocial factors with the MWL, and these factors, in interaction with each other, could predict MWL by 28%. Among the psychosocial factors examined, factor1 (β = 0.88, P < 0.01), (quality of leadership, social support from supervisors, recognition, justice, trust regarding management, predictability), and factor3 (β = 0.95, P < 0.01) (meaning of work, commitment to the workplace, influence, and role clarity) were among the factors affecting MWL. Conclusions: The study results indicated the significance of psychosocial factors in nurses' MWL. Hence, controlling and managing effective psychosocial factors could help reduce MWL. Given that nurses are the main element of care in the treatment team, the results of the current study may have several implications for policymakers and nursing managers. Since nurses’ MWL was in the range of high workload, workload management programs can help reduce MWL. By considering the prediction of nurses' MWL by psychosocial factors, some strategies should be considered by managers, including improving the quality of leadership, social support from supervisors, and also improving influence and role clarity.

Published: November 2024

The Úsobrno locality is known on the basis of fossil fauna findings, which were documented and published by Vašíček (1941). Field research has not been able to find the original locality yet. In this reason paleontological material which is deposited in the collections of ÚGV PřF MU was researched. We identified a total of 573 species which belonged mainly to the classes Gastropoda, Bivalvia, Anthozoa and Scaphopoda and compared with the original findings mentioned by Vašíček (1941). The age of the samples was determined to be the Lower Badenian.Based on the findings, especially hermatypal corals, it can be assumed that the sea was warm (above 20 °C), well oxygenated with a soft and hard bottom and mostly shallow. Some findings of fauna from deeper marine areas (Ranella fragment, ahermatypal corals) indicate mixing or postmortem transport during sedimentation.

Introducción: En el ámbito deportivo, el estado de ánimo y el nivel de grit son aspectos fundamentales que influyen significativamente en el rendimiento de los atletas. Objetivo: determinar la relación entre los estados de ánimo antes de una competencia y el nivel de grit en taekwondistas colombianos Metodología: Estudio de diseño no experimental de enfoque cuantitativo, de alcance descriptivo y correlacional con un corte transversal realizado en una población de taekwondistas colombianos. Los estados de ánimo se evaluaron mediante el instrumento de POMS. El grit fue medido mediante la escala de grit. Resultados: Se encontraron relaciones heterogéneas entre el grit y los estados de ánimo precompetitivos en taekwondistas colombianos. Se identificó una correlación negativa entre tensión y grit, así como entre tensión y consistencia de interés, indicando que una mayor determinación se relaciona con menor tensión. Otros estados de ánimo mostraron relaciones positivas con grit, aunque ninguna fue estadísticamente significativa. En cuanto a las medidas de tendencia central, se observó un nivel moderado de grit, destacándose la amistad y el vigor como estados emocionales predominantes antes de la competencia. Conclusiones: este estudio revela una correlación inversa entre el nivel de "grit" y la tensión precompetitiva en taekwondistas colombianos, indicando que una mayor determinación está asociada con una disminución en el estado de tensión. Los resultados muestran un nivel relativamente bajo de grit en comparación con estudios anteriores, lo que podría indicar una falta de enfoque en esta cualidad entre los deportistas colombianos. Los estados de ánimo precompetitivos sobresalientes en esta muestra fueron el Vigor y la amistad.

Over 1,100 experts have shared with us their concerns about COVID-19 and COVID-impacted areas in the immediate and longer term future. Researchers have also shared what further data or information they would like to see the Government release to understand the decisions that underpin its approach. This report outlines concerns about the impact of COVID-19 on work and employment. Experts are concerned that unemployment will rise as businesses lay off staff or close down. Some groups are likely to be more affected by lay-offs and may struggle to find another job. Experts are also concerned about the impact of working from home on productivity and health. Finally there are concerns about the labour market. Some industries in the UK, such as agriculture, may have too few workers to function in the long-term.

The ancient gramophones have a special worthiness in culture and industry and protection of these gramophones is essential. To analyze the internal structure of a gramophone, we need some methods that give us good information without destruction and damage to our valuable objects. One of these non-destructive methods is radiography testing (RT). In this method, which is based on the penetration of X or Gamma photons into materials, the internal information of the device can be obtained with radiography images. In this research, an ancient gramophone has been examined by radiography method and its internal structure and components have been examined. The Iterative Gaussian Convolution Filter (IGCF) image processing method has been used to remove the opacity and increase the contrast. The results indicate that components of the gramophone, such as the turntable motor and starter handle, along with their connections, are visible in the radiographic images. In the images reconstructed by IGCF, sharper edges and improved clarity of execution and internal connections are observed. This information aids repair and maintenance professionals in safeguarding the device from further damage.

Published: November 2024

High relative air humidity in humid climates slows the process of paddy drying and leads to rehydration. The use of a liquefied petroleum gas (LPG) refrigeration system for dehumidifying ambient air effectively reduces drying time and improves product quality in a non-destructive manner. This environmentally friendly method enhances both the quality of the rice samples and the efficiency of the drying process. This study examined the impact of dehumidification on Hashemi rice quality and moisture reduction, using the Response Surface Method to optimize drying conditions at three levels of temperature (40, 45, and 50 °C), air velocity (1.7, 2.2, and 2.7 m/s), and relative humidity (70, 80, and 90%). The results showed that dehumidification led to a moisture content of 6% and the lowest cracking rate of 2%. Temperature was the most influential factor, affecting responses by 73.09% under dehumidified conditions. Optimal conditions of 40 °C, 80% RH, and 1.7 m/s air velocity resulted in a cracking rate of 2% and a desirability index of 0.958. The Response Surface Method showed an excellent fit for the cracking index (R² = 0.98). These results highlight the LPG refrigeration system as an effective, non-destructive, and environmentally friendly method for drying paddy in humid regions, making it suitable for industrial applications.

Locke on Freedom and Freemen in the Two Treatises of Government
Authors: Losonsky Michael ,   Philosophy Documentation Center
Published: November 2024

In his Two Treatises of Government John Locke declared that all men are naturally free, but that they can consent with others to form a civil society under government. In fact, what “actually constitutes any Political Society, is nothing but the consent of any number of Freemen.” There are competing views about what socially defined groups Locke had in mind for the domains that are naturally free and those who consent to form a civil society, whether they are, for example, adult males with property or all adults. But I argue for a different approach. Depending on the context, Locke either referred to human beings who by nature have the disposition to be free when they reach maturity, or to those who in fact are actually free. Locke reserved the term “Freemen” to those that are in fact free, and not just dispositionally free. Locke believed that all human beings are born with dispositional freedom, which for Locke was an important normative feature that all human beings have at birth. Nevertheless, there are various conditions in which human beings, while born with the disposition to be free, are not in fact free, specifically, criminals, slaves, servants, children, most wives, and the mentally disabled.
Epistemic Character Damage and Normative Contextualism
Authors: Monypenny Alice ,   Philosophy Documentation Center
Published: November 2024

Recent proposals for a “critical character epistemology” attend to the ways in which environments, institutions, social practices, and relationships promote the development of epistemic vice whilst acknowledging that the contexts of differently situated agents demand different epistemic character traits. I argue that a tension arises between two features of critical character epistemology: the classification as “epistemically corrupting” of environments, institutions, or structures which promote the development of epistemic vice; and commitment to normative contextualism—the doctrine that the normative status (the status of a trait as a virtue or as a vice) of some or all epistemic character traits is context-dependent. I show how these two features lead to the claim that certain traits both are epistemic virtues and hinder the development of epistemic virtues. To make such an evaluation consistent, I propose a modified form of normative contextualism: dual-level normative contextualism.

Published: November 2024

Currently, the security of data has gained significant attention in modern life. Researchers have continued to address this issue. This work addresses image encryption in communication systems. It presents a proposed design and implementation of a cryptography system based on the Lorenz chaos oscillator. The paper methodology uses Xilinx System Generator (XSG) and Field Programmable Gate Array (FPGA) technologies to implement the chaotic system. To determine the approach that uses the least amount of FPGA resources while providing effective and efficient performance, the differential equations of the Lorenz chaotic system are solved via the forward-Euler and Runge–Kutta integration techniques. In the XSG environment, a secure communication system is constructed on the basis of the solution of the differential equations. After that, the planned communication system is implemented on the FPGA board and tested to encrypt images (coloured images). The histogram, entropy and other related security analysis factors are calculated and analysed to test the efficiency of the designed system. Six statistical methods were employed to provide a high level of image encryption in this work. Findings have shown that the proposed system generates (with stable, fast and robust performance) pseudorandom bits that can be successfully used to encrypt the data bits. The simulation and FPGA results are in good agreement; however, the security analysis factors prove that the system can be successfully adopted for image encryption purposes in real-time applications.

Published: November 2024

In the literature, two types of unstable nonlinear Schrodinger equations have been independently developed and studied. Each was derived by incorporating either a self-effect term or a time-space dispersion term into the standard nonlinear Schrodinger equation. Both models describe the time evolution of disturbances in unstable media. The primary contribution of this work is the combination of these two types into a single, new unstable version of the nonlinear Schrodinger equation. This new model is analyzed using two effective methods: the rational sine-cosine and the rational sinh-cosh functions. Additionally, a comparison test of the embedded unstable terms is conducted to assess their respective impacts on the stability of the Schrodinger model. Finally, graphical analyses, including 2D and 3D plots, are performed to validate the study’s findings.

This study aims to construct and investigate a novel (3+1)-dimensional model that combines both the Boussinesq-type and the Kadomtsev-Petviashvili (KP) equations, which is called a (3+1)-dimensional Boussinesq-KP-type (B-KP-type) equation. We demonstrate that the combined model does not exhibit Painleve integrability. However, it does provide two separate integrable equations: one of the (3+1)-dimensional Boussinesq-type equation and the other of the (3+1)-dimensional KP-type equation. The simplified Hirota’s direct approach can formally admit multiple soliton solutions for each integrable model. In addition, we employ Maple symbolic computation with the Hirota bilinear form to derive a class of lump solutions for each equation. Moreover, the (3+1)-dimensional B-KP-type equation is analyzed using the families
of tanh and tan methods for deriving traveling wave solutions, including shock wave solutions, periodic solutions, and others. Due to the significant correlation and wide range of applications of the Boussinesq-type and KP equations, the derived equations will play a crucial role in elucidating and interpreting various nonlinear phenomena observed in fluid mechanics and other fields of nonlinear physics and engineering issues.

Topological edge states with different frequencies located at different positions are called as the topological rainbow trapping effect. The topological rainbow capture has been studied extensively over the past years. In this work, for the first time to the best of our knowledge, we propose to realize the topological rainbow trapping based on the gradually shrinking and expanding the two-dimensional Kagome lattice. In order to simplify the topological structure, the one-dimensional array instead of the expanding Kagome lattice can also achieve the topological rainbow capture. In addition, the frequencies of rainbow trapping are modulated by the distance from the one-dimensional array to the Kagome lattice. The spatial positions of rainbow trapping at a fixed frequency are very sensitive to the dielectric constants of the environment and of dielectric columns, so we envisage potential applications in the area of topological sensors.

The transverse electric surface waves propagating along the surface
of the crystal characterized by a spatial dependence of the dielectric permittivity are
theoretically described. A hyperbolic profile of the dielectric permittivity of the crystal
is used to obtain an exact analytical solution to the wave equation, which is expressed
by Whittaker function. The influence of the parameters of the hyperbolic profile of the
dielectric constant on the localization of the electric field near the crystal surface is
analyzed. The dependencies of the effective refractive index on the parameters of a
hyperbolic profile of the dielectric permittivity are explored. The way to effectively
control the localization and intensity of the surface waves by changing the values of
the parameters of the hyperbolic profile using the obtained exact solution is found.

Thunderstorms and their associated hazards pose a significant threat
to society and the economy. In Europe, between 1980 and 2022, thunderstorms caused
an estimated EUR 190 billion in economic losses. In Romania, the rate of cloud-to-
ground (CG) lightning fatality is one of the highest in Europe. This study aims to
reevaluate the risk of lightning in Romania by updating the CG lightning climatol-
ogy for the period 2010–2022 and analysing long-term changes (1941-2022) in the
frequency of thunderstorm environments. Data were obtained from the Arrival Time
Difference Lightning Network (ATDnet) and the ERA5 reanalysis. On average, ap-
proximately 760,000 flashes occurred each year in Romania during the study period,
with a maximum mean annual flash density of approximately 6.5 flashes km−2 yr−1
over the Southern Carpathians. Approximately 75% of all flashes were detected in
June–August, with a peak in the afternoon hours. There is a general decrease in flash
density in Romania, but this trend is statistically significant only in western Romania.
The highest number of hours with thunderstorm environments (270–390 hours yr−1)
was predominantly observed in the mountainous regions of central and western Ro-
mania. There is a significant increase in the number of hours with thunderstorms per
decade, especially in eastern and southern Romania (>4 hours per decade). The re-
sults of this study allow for a better understanding of the risk posed by CG lightning in
Romania, improved forecasting of thunderstorms, and serve as a basis for developing
mitigation strategies to reduce the impact of CG lightning.
