Can Climbing Infrastructure Be Considered a Heritage?
Authors: Wierciński Hubert
Published: June 2024

In this article I ask how does movement infrastructural heritage emerge? What controversies and contrasting interests are associated with it? Might researching such conflicts shed light on the dynamics operating between societal and individual needs and landscapes? With that in mind, I draw upon ethnographic extracts from my research on rock climbing and mountaineering heritage in Poland and, to some extent, in Slovakia. I consider this kinaesthetic activity as an example of social practice where heritage, infrastructures and movement coalesce into a complex mixture of aesthetics, ethics, skills, and knowledge. These elements, learned and practised by generations of climbers, together turn rocky landscapes into vibrant arenas of sociocultural activity. They are also, however, marked by controversies related to climbing infrastructures. How do such tensions emerge and to precisely what do they refer?

Authors: Eizenhöfer Hanna
Published: June 2024

The author sheds light on the topic of the distribution of assets after liquidation of non-profit organisations, which has so far received little attention in the literature. In this work, she examines a variety of questions relating to civil and non-profit law. Amongst others, she discusses the purpose of such distribution and addresses the question of the determination of beneficiaries and the receipt of assets by them. The author also examines issues of non-profit law and discusses, for instance, the possible consequences of the subsequent cancellation of a statutory provision that regulates the distribution of assets after liquidation on the non-profit status of the organisation concerned.
Unveiling the Fourth Fundamental Circuit Element and Its Real-World Applications
Authors: Kehinde Femi Olaseinde
Published: June 2024

Memristors are a type of electronic circuit element that was first proposed in the early 1970s. Unlike traditional circuit elements such as resistors, capacitors, and inductors, memristors has last memory and can therefore be used to store information. They were initially considered a theoretical concept, but recent advances in nanotechnology have made it possible to create physical memristor devices and apply it in various aspect of life. Memristors are considered the fourth fundamental circuit element, alongside resistors, capacitors, and inductors. They have unique properties, such as the ability to store information in their resistance state, which makes them promising candidates for future computing systems. Memristors have been integrated into crossbar arrays, which allow for massively parallel computing with low power consumption. Memristor fabrication methods vary based on the materials used and the intended application. Thin-film deposition, nanoimprint lithography, and self-assembly processes are common techniques. The performance properties of the memristor, such as switching speed, endurance, and scalability, are influenced by the material selection, such as polymers or transition metal oxides. Memristors have a wide range of potential applications, including in the development of artificial intelligence and neural networks. They can also be used in memory devices, logic circuits, and sensor applications. Research is ongoing to further explore the unique properties of this lovely device and to develop various applications for it. The unique properties of memristors have also sparked interest in unconventional computing paradigms. Memristor-based systems have shown potential for implementing neural networks, cellular automata, and even analog computers, providing alternative approaches to solving complex computational problems. Memristor-based logic and arithmetic units offer advantages in terms of power efficiency and density compared to traditional transistor-based designs. This project shows the progress made in memristor technology, including the development of various memristive materials and device architectures. It explores the challenges associated with memristor fabrication, reliability, and scalability. Moreover, the paper highlights recent advancements in memristor-based applications, such as in-memory computing, deep learning accelerators, and brain-inspired computing systems. This piece provides an overview of the theory behind memristors, including their mathematical models and properties. It also discusses the different types of memristor devices that have been developed and their potential applications. Finally, it highlights some of the challenges and future directions in the field of memristor research.

Authors: Ahsan Kaleem Muhammad , Cai Jack , Chang Yao-Feng , Genov Roman , Amirsoleimani Amirali
Published: June 2024

One of the main issues that memristors face, like other hardware components, is non-idealities (that can arise from long-term usage, low-quality hardware, etc.). In this chapter, we discuss some ways of mitigating the effects of such non-idealities. We consider both hardware-based solutions and universal solutions that do not depend on hardware or specific types of non-idealities, specifically in the context of memristive neural networks. We compare such solutions both theoretically and empirically using simulations. We also explore the different non-idealities in depth, such as device faults, endurance, retention, and finite conductance states, considering what causes them and how they can be avoided, and present ways of simulating these non-idealities in software.

The ambulatory measures to minimize the agony and preventive strategies to reduce the incidence of hypokalemia were discussed. Beside the potassium salt therapy, the inclusion of Taurine in the therapeutic regime was rational and to be appreciated.
Radiosurgery for intracranial meningiomas
Authors: Zomosa Gustavo , Lühr Claudio , Bova Francisco , González-Johnson Lucas , Rojas-Solé Catalina , Troncoso Lene , Miranda Gonzalo , Lorenzoni José
Published: June 2024

The classical definition of stereotactic radiosurgery (SRS) involves administering a high dose of radiation within a limited treatment area. More recently, it has also encompassed the concept of hypofractionated radiosurgery, which involves delivering radiation over up to five treatment sessions. Intracranial meningiomas (IM) are commonly encountered primary brain tumors. Currently, there has been a rise in the number of asymptomatic individuals with IM, who subsequently require treatment due to the development and onset of symptoms. Small and medium-sized IM treatment standard options encompass radical surgery; however, this may not always be feasible due to surgical risks and patient preferences. In contrast, SRS stands out as an effective tool for managing tumor growth and alleviating symptoms. It is an outpatient procedure that eliminates the need for general anesthesia and extensive postoperative care. This holds particular significance in countries with long surgical waitlists, providing a cost-effective and low complication alternative. Furthermore, SRS plays a crucial role not only in grade I IM but also in addressing some cases of recurrent and residual grade II and even grade III IM. It also has a place in the management of radiation-induced meningioma.
Shifting Tides: Unraveling the Sociological Fabric of Climate Change
Authors: Shrestha Anita , Krishna Shrestha Shyam
Published: June 2024

This study shifts its focus from the predominant biophysical perspective of climate change (CC) to a sociological lens, particularly in the context of the Ramechhap district, Nepal. It delves into the local perceptions of CC and emphasizes its sociological impact on livelihoods. Employing a constructivist theory and the complex human—environment systems, the research extensively explores institutional, structural, and societal pathways of adaptation. The study employs a qualitative data, utilizing purposive sampling and ethnographic methods such as observation, case studies, KIIs, and FGDs. The findings underscore the challenges faced by farmers in the Ramechhap, particularly those dependent on forest, agriculture and livestock, due to the impacts of global warming. Issues such as increased drought, temperature fluctuations, altered monsoons, and other climate-induced changes emerge as disruptive factors affecting the agricultural system, rendering it vulnerable and less productive. To counteract these climate risks, farmers in the Ramechhap employ adaptive measures grounded in traditional and local knowledge concurrently integrating new technologies. Adjustments to crop varieties based on climate disturbances and the establishment of collective networks and social relations through the exchange of experiences are crucial strategies. The research contributes valuable sociological insights into the local dynamics of CC and proposes holistic CC policies.
Modelling as an Instructional Strategy in Multilingual Classrooms
Authors: Hilda Matiso Nomasomi
Published: June 2024

This chapter introduces modelling as an instructional strategy used by teachers to facilitate comprehension in multilingual classrooms. Modelling is a teaching approach in which the teacher openly demonstrates to the students how to execute tasks. Studies have indicated that a deficiency of modelling causes competency in the learning and teaching environment to take longer. Reinforced by theoretical frameworks such as sociocultural theory and culturally responsive pedagogy, this analysis adopted an interpretive paradigm and a qualitative approach. Semi-structured interviews were administered to six conveniently chosen English second language teachers in a Higher Institution of learning in South Africa. Outcomes of the data, which were thematically analysed, indicated that scaffolding through explicit vocabulary instruction, contextualised learning and collaborative activities, and the use of multimedia texts through flipped classrooms could be effective strategies in multilingual classrooms. Enhancing the quality of learning in both online and offline learning environments necessitates the use of effective teaching strategies like modelling and scaffolding, in addition to providing enough academic assistance. With a variety of developing pedagogies and technology advancements in the post-COVID-19 era, instructors must be proficient in applying updated instructional approaches that will empower students to process knowledge in a way that will satisfy twenty-first-century demands.

Cardiac resynchronization therapy (CRT) is an established treatment for select patients with systolic heart failure, left ventricular conduction delay, and dyssynchronous contraction. Landmark trials have shown CRT’s benefits on symptoms, exercise capacity, reverse remodeling, hospitalization rates, and mortality. However, limitations exist including sub-optimal patient selection, procedural complexity, high non-responder rates, and device-related adverse effects. This review summarizes the evolution, physiology, clinical trial evidence, patient selection, delivery, and optimization of CRT. Key areas covered include guidelines for CRT use, invasive and noninvasive imaging to improve outcomes, alternative pacing sites to enhance response, and advances in lead technology and implantation techniques. Gaps in current knowledge are highlighted along with future directions for research to refine CRT utilization and improve real-world clinical outcomes. With further studies to address remaining questions, CRT is poised to become an even more effective therapy for heart failure patients with dyssynchronous cardiomyopathy.

Published: June 2024

Schools that educate multilingual learners need leaders who can ensure that the curriculum, instruction, and assessment align with the needs of students. Each of these areas—curriculum, instruction, and assessment—impact the opportunities students have to learn. To ensure that the needs of multilingual learners are met, leaders design coaching and professional learning opportunities for teachers and provide feedback to teachers to continue their development. In this chapter, we review the leadership moves that are necessary to ensure that these aspects of schooling are strong and meeting the needs of students. In addition, we focus on the support that must be in place to ensure that students feel they belong and are valued.

Authors: Xu Baosheng , Jin Runze , Liu Ni , Wang Hui
Published: June 2024

Integrated molding of composite liquid oxygen tanks has become a crucial technology for aerospace carriers to shorten manufacturing cycles, improve carrying efficiency, and reduce production costs. Operating in an environment of −183°C, carbon fiber-reinforced resin composites face challenges such as extreme low-temperature service conditions and incompatibility with liquid oxygen due to the coupling effects of mechanical, thermal, and chemical fields. This chapter focuses on developing a modified epoxy resin matrix that is both ultralow temperature resistant and liquid oxygen compatible, essential for manufacturing composite liquid oxygen tanks. By improving the durability and fire resistance of the epoxy resin, this research introduces a novel dual-system macromolecular network interpenetration and interchain chemical crosslinking mechanism, improving mechanical properties at both room and ultralow temperatures. Moreover, two newly developed phosphorus/nitrogen-based reactive flame retardants are synthesized and added to the resin, notably improving both flame retardancy and compatibility with liquid oxygen. The resulting modified epoxy resin systems demonstrate superior mechanical properties at both room and ultra-low temperatures, making them suitable for manufacturing carbon fiber-reinforced composite materials for liquid oxygen tanks. The findings highlight the potential of these materials to meet the stringent requirements of aerospace applications.
Cybercrimes as a Potential Threat to National Security: The Case of Kosovo
Authors: Demolli Haki
Published: June 2024

The focus of the chapter is cybercrime and the danger it poses to the national security of Kosovo. In order to present the situation of this problem in Kosovo, the author concentrates on cyberattack cases in which the national security of Kosovo has concentrates on cyberattack cases in which the national security of Kosovo has been threatened during the last few years. Kosovo’s national security is being attacked by various forms of cybercrime, which are mostly carried out by cybercriminal groups from countries that oppose Kosovo’s independence, such as Serbia, Russia, Bosnia, and Herzegovina. The author analyzes the volume and dynamics of cybercrime offenses committed in Kosovo over the last 8 years. Analytical studies are conducted on legislative measures. Among such measures is the cyber security legislation, which in Kosovo is sufficient and meets the needs of its citizens, as it is in accordance with aquis communiter, legal standards, and other legal acts of the EU. The various state mechanisms that Kosovo has established during the past decade, which are solely dedicated to preventing and combating cybercrimes in this small European state, have also been addressed. The new types of cybercrimes pose a significant challenge for Kosovo, which is constantly evolving, affecting various computer systems and social values, including national security.
An Ensemble Method for Supervised Learning for Intrusion Detection and Network Forensics
Authors: Chiche Zewdu Alebachew , Kadi Kumssa Hiwot
Published: June 2024

With the rapid expansion of Internet usage, cyber-attacks are becoming a point of interest for network security researchers. While companies are interested in providing their services over the Internet, their services do not enjoy appropriate security protection. Consequently, they are costing millions of dollars with network threats. Accordingly, current research suggest that ensemble methods may have advantages over individual base learners in intrusion detection problem. In this research work, we propose a new intrusion detection model combining an ensemble learning method and the expert system. In this study, first, we explore the three popular ensemble learning methods (namely boosting, bagging, and random subspace) with three individual base learners (random forest, Bayes net, and SMO) for network intrusion detection. Moreover, the NSL-KDD intrusion dataset was experimented to evaluate the effectiveness and efficiency of ensemble learning methods for intrusion detection. The performance of ensemble classifiers on the NSL-KDD dataset is tested in terms of average prediction accuracy. On the basis of experiments, empirical results show that general learning methods considerably improve the performance of base learners. Among the three ensemble methods, AdaBoostM1 boosting ensemble method based on the random forest base learner achieves the better comparative results. These results show that ensemble methods are appropriate for intrusion detection and further combined with the expert system for a knowledge-rich intrusion detection model.

Pyrolysis techniques use thermal energy to degrade large molecules into smaller and volatile molecules, which can be analyzed by gas chromatography to determine the composition or structure of the initial sample. A laser system coupled to a GC/MSMS, for analysis of these species, gave rise to the technique called Laser MicroPyrolysis-GC/MSMS (LmPy-GC/MSMS). The laser micropyrolyzer is a hyphenated system with a laser source, an optical microscope, and a GC/MSMS technique. In this hyphenated technique, a collimated, short-duration laser beam with a large amount of energy can be focused on isolated components, or a macromolecule inside a heterogeneous matrix, promoting the thermal cleavage and producing smaller components, which are finally analyzed and characterized by GC/MSMS. The LmPy-GC/MSMS has been proven to be able to supply important molecular data on organic fossils, coals, source rocks, etc., improving the knowledge and the understanding of the compositions and opening a horizon in the study of several heterogeneous materials.
Perspective Chapter: Development, Sustainability, and Precautionary Principle – Narratives and Ambiguities
Authors: Pinto Albuquerque Cristina
Published: June 2024

The chapter seeks to analyze how precautionary principles and different conceptions of sustainability are evident in the main international resolutions and summits on development and the environment since the Stockholm Conference (1972). These conceptions determine different ways of conceiving individual and collective responsibility, giving rise to a kind of “virtue ethics” of diffuse contours. In this context, the aim is to discuss the ambiguities and paradoxes of sustainable development discourses and the precautionary approaches that are often associated with them. If, on the one hand, the precautionary principle can be seen as a restrictive and minimalist approach to preventive policies, which should presuppose a multidimensional articulation between anticipation, minimization, and reparation, anchored in a global debate and commitment, and on the other hand, the adoption of more protective and punitive measures (especially if they are only localized) can embody (new) (un)balances between freedoms and the common good, leading to a kind of “scientifically backed authoritarianism”. We, therefore, need a profound debate on the foundations of (global) citizenship, governance, and participatory scales, assuming the interdependence between the economy, society, politics, and the environment.
An Update on the Etiopathogenesis and Management of Morbihan Disease: A Narrative Review
Authors: Abu El-Hamd Mohammed , Aboeldahab Soha
Published: June 2024

: Morbihan disease (MD) is a rare and infrequent condition primarily affecting adults of both sexes in their third and fourth decades of life. Patients with MD typically present with asymptomatic, recurrent bilateral symmetrical pitting edema, which has an insidious onset and a progressive course. This edema affects the upper two-thirds of the face, including the forehead, glabella, periorbital area, cheeks, and nose, with or without erythema. Over time, it evolves into persistent solid, non-pitting, asymptomatic edema that is neither painful nor pruritic. Morbihan disease may cause facial contour deformity and sometimes narrowing of the visual field. The etiopathogenesis of MD remains unknown, and currently, there is no specific treatment for the condition. This review article provides an update on MD, aiming to increase awareness and knowledge about its etiopathogenesis and management.

Published: June 2024

Since the organic revolution was started more than ten years ago, due to numerous challenges, it has not been able to attain the growth in popularity that was expected. Most people think of organic farming as stopping to use synthetic inputs and substituting them with organic ones, such as utilizing organic manures and natural plant protection techniques in substitution for synthetic fertilizers and pesticides. Instead of using harmful inputs, organic agriculture utilizes natural processes, biodiversity, and cycles that are adapted to local conditions. The main objective of organic farming is to create a self-sustaining agricultural system that works in balance with nature, produces healthy food that is both environmentally and economically feasible and enhances the local biodiversity and all of its components. Among the 172 nations that practice organic agriculture, India stands out due to its 6, 50,000 organic producers, 699 processors, 669 exporters, and 7,20,000 cultivated hectares. The expanding domestic market will allow India to grow more quickly. India's local markets must expand for the organic movement to be successful there. India has a great deal of potential to produce crops organically and establish itself as a significant provider of certified organic products in the worldwide organic market thanks to the large area under naturally organic/default organic production.
INTEGRATED NEMATODE MANAGEMENT (INM)
Authors: Abhishek Mr. , Shiwangi Mr.
Published: June 2024

Integrated Nematode Management (INM) is a set of strategies aimed at controlling nematode populations in agricultural systems. Nematodes are microscopic, worm-like organisms that can cause damage to crops, and their control is important for sustainable and profitable agricultural production. INM involves combining different control methods in a coordinated way to manage nematode populations while minimizing the negative impact on the environment. The components of INM typically include cultural practices, such as crop rotation and the use of resistant varieties, biological control, such as the use of natural enemies of nematodes, and chemical control, such as the use of nematicides. The goal of INM is to use these different approaches in a complementary manner so that each method enhances the effectiveness of the others while minimizing the overall impact on the environment. For example, a farmer might use crop rotation to break the life cycle of nematodes, followed by the use of nematode-resistant crop varieties to reduce nematode damage. In addition, the farmer might introduce beneficial nematodes or other natural enemies to control nematode populations and use chemical control only when necessary and with minimal environmental impact. Overall, INM is an important approach for managing nematodes in agricultural systems, as it allows farmers to reduce nematode populations while minimizing the negative impact on the environment and maintaining the sustainability of their agricultural systems.
