In the mining industry, smart surveying and exploration operations for the minerals are essential during mining missions. Usually, these missions are performed in remote areas that do not have a wireless communications infrastructure. This paper proposes to use the unmanned aerial vehicle as a relay communication node between the exploration team and the ground control station. UAV can act as a relay node to provide mobile, flexible, and reliable communication links in remote environments and complex topologies. In this work, the (...) pathloss models in millimeter-wave technology are considered because they provide massive data rates for line of sight scenarios. The optimization problem of identifying a 3D location and trajectory of the UAV relay node is formulated to maximize the total team members’ data rate. Because the problem is non-convex, the particle swarm optimization algorithm is used to solve it and determine an efficient location and trajectory of the UAV. (shrink)

The research seeks to ascertain the influence of the Needham and Cosgrove-Osborne models on the comprehension of educational foundations among students at the Faculty of Education. Employing a partially controlled experimental design, the researcher randomly selected a control group from Division C, with Division A representing the first experimental group and Division B the second. The study involved 92 participants, with 30 students in each experimental group and 32 in the control group. To ensure statistical equivalence among the three groups, (...) the researcher utilized one-way analysis of variance (ANOVA) to assess variables such as chronological age (in months), intelligence test results, and the previous year's Grade Point Average (GPA). A test was crafted to evaluate concept acquisition, with its validity and reliability duly established. Upon statistical analysis of the students' responses using ANOVA and the Scheffe test to pinpoint differences in means, the findings revealed significant disparities between the average scores of students in the first and second experimental groups, who studied the subject matter using the Needham, Cosgrove, or Osborne models. The researcher posits that the Needham and Cosgrove-Osborne models should be integrated into teaching practices, given their demonstrated effectiveness as instructional paradigms. (shrink)

This article explores the paradoxical relationship between politics and violence in the concept of political violence. By examining the works of prominent theorists, such as Hannah Arendt and Frantz Fanon, the article highlights both the difficulty of separating politics and violence, and the improbability of formulating a harmonious relationship between them. Engaging with some of Michel Foucault’s work on power and violence, the article begins to formulate a theoretical approach that conceptualizes political violence in its inherently paradoxical condition.

The problem of the research was represented by the lack of interest of many teachers in the use of diversification and change in various exercises, despite the positive role it plays in generalizing the motor program for any fencing skill, even though most of its skills are characterized by difficulty in performing them, which requires providing the largest number of motor programs in order to be The learner has full readiness and preparedness, and the research aims to prepare various exercises (...) to develop sensory perception and accuracy in performing complex attack skills and the stabbing movement. And to identify the effect of various exercises in developing the students’ kinetic awareness and accuracy of combined attack skills and stabbing movements in fencing. Use the researcherthatThe experimental approach with two equal groups. The research sample represented the students of the third stage of the Department of Physical Education and Sports Sciences at the Islamic University for the academic year 2022-2023 AD, and they numbered (50) students. They were selected by a simple random method, and were divided into two groups (experimental and control), and the number of each group was (25). ) student. The experimental group applied the various exercises prepared by the researcherthatAccording to the stages of building the motor program for learning epee skills in fencing, it was included among the educational units approved in colleges of physical education for third-year students, at the rate of one educational unit per week, amounting to (6) educational units. The time of the educational unit was (90/min), and the time of the educational unit was divided into the preparatory section. (15/d), the main section (65/d), and the final section (10/d). The most important conclusions were that there was a significant effect of the various exercises in developing sensory-motor perception and accuracy of performance in learning fencing skills. The most important recommendations are the need to pay attention to various exercises during educational units because they help learners expand their educational awareness and thus reflect on their performance of skills.

Thereby, EIDs pose huge threats to health care infrastructures everywhere due to unprepared infrastructures and poor immunity levels of population. It discusses how key role players, the hospital administrator, would play a big role in managing EID infections as well as strategies related to infection control. Such vital factors include resource allocation, implementation of policies, training, and building a culture for safety as well as working under an interdisciplinary approach. COVID-19 pandemics are best used as case studies both where successes (...) occurred and where infection prevention lacked. Findings point toward robust surveillance, real-time data analytics, and the emotional support required for the healthcare workers involved in combating EIDs. The work discusses the socio-economic implications of EIDs and the utmost need to adapt strategies at resource-poor settings. Adding their recommendations with proper training, technological adaptations, and well-defined policymaking, they can decrease the impact of EID. By including technology, teamwork, and psychological impacts, the hospital administrators can develop such healthcare systems that can take on future challenges. It is a transformational effort that proactive leadership and innovation can make to combat the global health threat. (shrink)

Hepatocellular carcinoma (HCC) presents a significant problem that necessitates a greater understanding of its underlying molecular complexity in order to improve diagnostics and therapies. Recent studies have shed light on the critical role that mitochondrial dysfunction plays in the development and course of HCC. Once thought to be primarily involved in the synthesis of cellular energy, mitochondria are now known to be key participants in the regulation of a variety of cellular functions that go beyond bioenergetics. The purpose of this (...) review is to elucidate the diagnostic and therapeutic implications of mitochondrial dysfunction in HCC by synthesising ideas from conventional and contemporary scientific literature. Within diagnostics, the discovery of mitochondrial biomarkers such as mutations in mitochondrial DNA and abnormalities in respiratory chain complex activities provides a state-of-the-art viewpoint for the timely identification and accurate description of HCC. In addition, non-invasive imaging methods that focus on mitochondrial function offer prospective means of improving clinical diagnostic accuracy. Moving on to treatment, a growing area of study investigates how mitochondria-targeted therapies might be used to treat HCC. Novel substances and repurposed medications with the potential to induce selective apoptosis in cancer cells, reduce oxidative stress, and restore mitochondrial homeostasis are highly promising. In the fight against hepatocellular carcinoma, an understanding of the complex interactions between mitochondrial dysfunction and HCC opens new diagnostic opportunities and paves the way for individualised treatment plans.
