Transformational Leadership and the Modern Presidency
Authors: Demczuk Andrzej
Published: January 2025

This book seeks to analyze the leadership of three presidents: Bill Clinton, George W. Bush, and Barack Obama, as well as to examine the impact of the presidents’ leadership had on the leadership of the advisers they worked with during their presidencies. Transformational leadership, a term first introduced by James MacGregor Burns, describes a process in which “leaders and followers help each other to advance to a higher level of morale and motivation.” In order to measure transformational leadership, Bernard M. Bass’s model - which includes four elements: an idealized influence, inspiring motivation, intellectual stimulation, and individual treatment - is applied throughout. It is crucial to conduct an analysis of the relationships between the examined three presidents and their advisers in order to demonstrate if the subordinates excelled in leadership because of the presidents’ leadership skill.
Removal of an Aural Foreign Body by Magnetism
Authors: Prentice Emily , Bartlett Emily , Ilgen Jon
Published: January 2025

Case Presentation: A male patient in his thirties with a history of polysubstance use presented to the emergency department (ED) due to an abrasion on his left forehead caused by banging his head against a wall in self-injurious behavior. A non-contrast computed tomography of the head obtained to rule out intracranial injury incidentally demonstrated a radiodense foreign body in the left external ear canal. A round metallic foreign body was subsequently visualized on otoscopic examination. The aural foreign body (AFB) was identified as a metallic bead that the patient had placed into his own ear; however, he reported no associated discomfort, hearing changes, or discharge. Traditional approaches for removing AFBs were considered; however, due to the position and smooth surface of the bead, there was concern they would be unsuccessful. Recognizing the metallic nature of the AFB, the clinician held a ceramic donut magnet adjacent to the patient’s ear and subsequently extracted the AFB without complication or patient discomfort. Discussion: Aural foreign bodies account for a significant number of visits to EDs annually. Removal of AFBs can be challenging, often requiring specialized equipment or specialty referral for management. Using magnetism over short distances for the purpose of extracting metallic AFBs presents a low-cost, low-risk intervention. When used in applicable scenarios, this technique can decrease the need for specialty referral and can especially benefit patients seeking care in less-resourced settings.

Authors: Acha Stefalo , Yi Sun , Ferguson Frederick
Published: January 2025

The primary aim of this research is to create a comprehensive neural network model that can effectively regulate the position of the leading-edge shock in a scramjet by manipulating the required backpressure, thereby achieving, and maintaining hypersonic speeds. By utilizing computational fluid dynamic data, a dynamic model is constructed using a neural network-based approach to control the positions of the leading-edge shock train. The scramjet isolator, which is a duct where pressure increases from the inlet to the combustor via a series of shock waves, necessitates precise control of the leading-edge shock locations during scramjet operation. The model employed in this research project is a neural network adaptive controller implemented in MATLAB/Simulink software, which accounts for the nonlinear characteristics of the plant and predicts its future behavior. To enhance control performance, a robust controller is employed, integrating a learning rule that reduces the error percentage throughout the system's lifespan. The neural network is trained using flight behavior datasets, enabling it to learn from a set of training patterns. Plant identification is achieved through a neural network, capturing the system dynamics, and enabling the neural network to function as a controller. Additionally, the controller's performance is validated through simulations and optimization analyses. This research presents an adaptable, robust, and effective control system that provides added reliability and reduces disturbances.

Published: January 2025

In the industrial world, many tools have been made to facilitate human work in carrying out control and measurement that is made automatically in a production process. Because in some parts of a production process in the industry that is done manually is no longer effective so that accurate and precise automatic control is needed. The control that will be used in this study is the Integral State Feedback (ISF) control with Arduino Uno as a microcontroller to design and run the system. The actuator used is a 12V water pump with the sensor used is the YF-S401. The system will run the ISF control as long as the data is less than 300 and if it reaches 300 data, the system will stop processing the ISF control and turn off the 12V water pump. The sensor reading error obtained is 27%. Parameters Ki = 0.3, K1 = 6, and K2 = 2 obtained from MATLAB Simulink can be applied to the research tool but have a slow system response Delay Time and Rise Time, so the researcher made a modification parameter with a value of Ki = 1, K1 = 6, and K2 = 2 and obtained a faster system response Delay Time and Rise Time. So it can be concluded that the best parameters for this study use modified parameters.

Published: January 2025

This paper tackles the tracking position control dilemma of permanent magnet linear synchronous motors with parameter uncertainties and load force disturbance. Adaptive nonlinear backstepping control augmented with sliding mode control (SMC) is proposed to solve the problem of load force distribution. The backstepping is a recursive control technique where its stability is ensured at each step. However, its sensitivity to uncertainties, disturbances, and electromagnetic noise leads to unwanted performances. SMC is a well-known nonlinear robust approach for uncertain dynamical systems and reduces its parametric adaptive laws.  However, implementing this technique in real-time applications is stopped by its main shortcoming, the undesirable chattering phenomenon.  The saturation function is used to reduce the chattering phenomenon.  The incorporation of these approaches is a promising solution to provide a suitable position tracking of PMLSM in the presence of parameter uncertainties and load force disturbance. The simulation tests have been performed on the PMLSM system to prove the effectiveness and robustness of the proposed controller law.  The results highlighted satisfactory position tracking performance in transient conditions and steady-state and under different load force disturbances.

Aim
The aim of this study was to determine nursing students’ opinions about the clinical learning environment of the Pediatric Nursing course and the affecting factors.

Method
In this descriptive and cross-sectional study consisted of 87 nursing students who were enrolled in the Pediatric Nursing course and completed their clinical practice. In this study, “Demographic Information Form” and “The Clinical Learning Environment, Supervision and Nurse Teacher Scale” were used.

Results
The highest sub-dimension of the Clinical Learning Environment, Supervision and Nurse Teacher scale of nursing students was nurse faculty member and the lowest sub-dimension was nursing care in the clinic. 59.8% of students are satisfied with the clinical learning environment. This study, academic achievement was found to be significant only in the clinical learning environment sub-dimension of the Clinical Learning Environment, Supervision and Nurse Teacher Scale and had no significant effect on the other sub-dimensions (p>0,050). It was found that the clinical practice supervisor variable was significant only in the faculty member score sub-dimension of the scale and was not significant in the other sub-dimensions.

Conclusions
This study shows that the students scored well in all subscales of the Clinical Learning Environment, Supervision and Nurse Teacher Scale and were satisfied with the clinical learning environment.
Biogas as fuel for the lowest-level power plants
Authors: Ciurkot Miłosz , Olczak Piotr
Published: January 2025

In the face of European climate policy, the aim of which is to achieve climate neutrality by 2050, we are still looking for alternatives to traditional fossil fuels. Apart from the obvious solutions offered by wind and solar energy, it is worth paying attention to a still undeveloped, but potentially developing branch of energy, which is generating energy from biogas. Poland currently produces 638 million m3 of biogas per year and has biogas installations with a total installed capacity of 276 MW. However, these numbers still do not fully satisfy both Polish possibilities and needs. This study analyzes the current use of this fuel in the Polish energy sector, as well as the possibilities and future prospects for biogas as a fuel for distributed generation power plants in Poland. The current review of the use of biogas as a fuel clearly indicates that biogas is not a commonly used renewable energy source with a total share of power among other RES sources of 4.2%. The analyses also indicated that the maximum theoretical Polish potential for biogas production may reach even 4.2 billion m3. At the end of the article, simple financial analyses were made regarding the profitability of investments in agricultural biogas plants, and their results showed a high profitability of investments in such energy units (theoretical payback periods of financial outlays are only 4 years).
