Authors: Gupta Rohit , Mahajan Diksha
Published: January 2024

The problems such as evolution and withering of population, immersion of glucose by the body, escalation of epidemics and reversal of gross domestic product (GDP) over time, Law of heating or cooling given by Newton, radioactive disintegration law, and velocity of an object which is falling vertically downwards under the operation of gravity pull, in physical or basic sciences, are delineated by differential equations. These problems delineated by differential equations are generally solved by the calculus method which requires complicated computations. In the present article, an advanced integral transform-Rohit transform (RT) is conferred for solving the problems delineated by differential equations in physical or basic sciences. The results come by confirming that the RT is a simple and more effective scientific tool for dealing with such problems delineated by differential equations in physical or basic sciences than the ordinary calculus method.
Overview of a Gas Turbine Blades Power Plant
Authors: M. Wurood Asaad , Khenyab Ali yousif , Shaker Lina M. , Kdhim Ruaa Hatem
Published: January 2024

Power plants that employ turbine blades to generate electricity usually need them to have certain qualities, like high strength, fatigue and corrosion resistance, and temperature tolerance. Super alloys and ceramic composites are common materials used in their construction. Defects or imperfections that might impair the performance and lifetime of turbine blades are a typical issue in their production. Casting flaws, material inclusions, and inadequate cooling during manufacturing are a few examples of these faults. Power plants use strict inspection procedures and quality control measures to reduce these problems and guarantee the dependability of their turbine blades. Improvements in material composition and design are usually required when changing the materials used in turbine blades to boost their effectiveness and performance. Depending on the particular use and intended result, turbine blades can undergo a variety of alterations. Advanced alloy material modifications, coatings, ceramic matrix composites (CMCs), airfoil design optimization, cooling technologies, and tip modifications are a few examples of typical modifications. It's important to note that the specific modifications applied to turbine blades can vary widely depending on the type of turbine (gas, steam, wind, etc.), the operating conditions, and the goals of the modification.

Tunnels as Temples of 'New Green India': Dominant Narratives of Himalayan Dam Building
Authors: Asher Manshi , Negi Vivek
Published: January 2024

The dramatic unfolding of the Joshimath crisis in Uttarakhand, India, has brought the world’s attention once again to the Himalaya. The contribution of a 520-megawatt hydropower dam to land subsidence is squarely in the spotlight. River valleys with bumper-to-bumper hydropower dam building, especially in the North Western Himalaya, in the past decade and a half or so, have witnessed frequent slope de-stabilisation, landslides and seepages. Unlike the visible dispossession of rural—often adivasi and dalit— populations in reservoir based dam affected areas, even establishing and ‘scientifically’ correlating cascading hazards with human impacts of the ‘invisible’ activity of run-of-the-river dams in the relatively sparsely populated regions of the Himalaya, has been an uphill battle for impacted mountain people. This article examines the conflict around hydropower development in Himachal Pradesh to understand the trajectory of State policy, dominant narratives and responses of affected communities. Tracing the history of such contestation in the 180 MW Bajoli Holi hydropower project in Chamba’s tribal belt Bharmour, we illustrate the complicity of project proponents, regulatory institutions, political actors, scientists and the judiciary in transferring the project’s risks to local inhabitants and the environment. The burden of building fresh evidence, staking claims and posing counter-narratives lies unfairly with the dispossessed as they struggle for safety and survival.

How Can Business Best Approach Human Rights in Third-Party Litigation Funding?

Conceived as a human right, access to justice is part of the rule of law, well recognised in several international instruments (Arts. 8 and 10 of the UDHR; Arts. 2.3 and 14 of the ICCPR; Arts. 6 and 13 of the ECHR and Art. 47 of the CFR). The present fulfilment of this right includes forms of privatisation like private insurance covering the costs of litigation, contingency-fee arrangements between lawyers and clients, crowdfunding applied to support the costs of litigation, and third-party litigation funding (TPLF). In the present article, I will restrict my analysis to TPLF as a private form of investment designed to finance access to justice. The aim of this article is to provide arguments in support of the regulation of TPLF as well as normative guidelines to inform that regulation. For this purpose, I will start by presenting different approaches to TPLF and will then assess – from the human rights perspective – examples of regulation. This evaluation intends to determine to what extent these regulations are in line with the human rights matrix of obligations: namely, the duty to respect, to protect and to fulfil human rights. Finally, I will present conclusions following the results of this evaluation and suggest guidelines to improve future regulations.

Legal Protection For Doctors in Running A Practice
Authors: Sinaga Hasudungan , Pondang Josafat
Published: January 2024

Purpose: Legal problems that may arise as a result of using hospital services when a general practitioner is on call to carry out medical procedures that are the rights of the treating doctor. This article aims to determine the practice of implementing health law in relation to the protection of doctors who carry out daily practice in Indonesia. This article also reviews deviations in health law in relation to medical practice in Indonesia. In the end, the author intends to offer and provide solutions to problems and irregularities in the implementation of health law in medical practice so it is hoped that this article can become a reference in increasing compliance with health law, especially regarding the protection of doctors when carrying out medical practice.
 
Theoretical Framework: Legal protection is something an effort to protect individual interests by allocating a human right of power to the individual to be able to act in the context of those interests. Legal protection is basically protection given to legal subjects in the form of legal instruments. Doctors who carry out their profession have the right to receive legal protection as regulated in Article 50 of Law Number 29 of 2004 concerning Medical Practice. Hospitals are obliged to provide legal protection to doctors who work in their hospitals in accordance with the hospital's obligations as regulated in Article 29 paragraph (1) letter (s) of Law Number 44 of 2009 concerning Hospitals. In Indonesia, laws and regulations do not yet clearly regulate legal protection for doctors.
 
Method: This study uses normative legal methods supported by literature reviews from national and scientific journals international. The main focus of the subject is law, which is understood as social standards or regulations that guide everyone's behavior.
 
Results: The research results show that as long as doctors follow standard operating procedures in their practice, they are allowed to carry out medical procedures to save lives in emergencies. Professional standards refer to a set of minimum competencies (knowledge, abilities, and attitudes) that a doctor must possess.
 
Conclusions: Legal protection for medical professionals practicing in hospitals is necessary to ensure that the health services offered comply with medical standards and medical ethics. At the same time, improving health service standards needs to be supported by providing a supportive work environment for doctors.

Legal experts and advocates recognize Indonesia’s Simple Proof Test for bankruptcy as ineffective and ‘too simple’ where Courts turn a blind eye to rule out matters requiring a thorough legal and factual assessment, hence the current Bankruptcy Bill basing future revisions on United States (“US”) practices. However, the simple proof test remains.
 
Methods: This research is a normative legal research with applying the statutory and comparatives approach to analyze the research questions concerned with descriptive qualitative.
 
Conclusions: The result of this research found that applying the same standards in an entirely different regime would not reap the benefits intended. Therefore, a thorough assessment should replace the simple proof test entirely.

Evaluating Combination of Solvent-Based Recycling and Mechanical Recycling of ABS Materials for Mitigating Plastic Pollution and Promoting Environmental Consciousness
Authors: Türkan Oytun Tuğçe , Çetin Esra
Published: January 2024

Plastics continue to transform everyday life with their versatility, lightweight, and durability, although the escalating issue of plastic pollution necessitates urgent action. The surge in single-use plastics and a disposable culture worsens this problem, emphasizing the need to reduce plastic production, establish circular material models, and phase out single-use plastic products.

Addressing the environmental impact of plastics requires the development of technologies enabling more efficient recycling solutions, converting waste plastics into harmless substances. Recycling methods, combining solvent-based recycling and mechanical recycling, are pivotal in this context.

This study specifically focuses on the solvent-based and mechanical recycling of ABS materials. Wiring devices are prepared using a blend of 70% virgin ABS material and 30% recycled ABS (rABS) material, with this loop repeated three times. The aim is to evaluate the quality and acceptability of products derived from the blend of virgin and recycled ABS material after three times of cycle. Wiring devices, manufactured from mechanically ground broken ABS, undergo rigorous testing in each cycle. The experiments aim to assess the suitability and performance of recycled ABS material for mass production, facilitating an in-depth analysis of the material's life cycle. The mechanical test results demonstrate favorable outcomes for the recycled acrylonitrile butadiene styrene (rABS) materials, indicating comparable performance to the reference ABS virgin grade. While a marginal reduction in impact strength and tensile strength is observed when juxtaposed with the reference ABS virgin grade, the overall mechanical characteristics of rABS, remain consistent through successive recycling loops. These findings underscore the viability and resilience of rABS materials, positioning them as promising candidates for sustainable and environmentally conscious applications within the realm of polymer engineering. Through these efforts, the study contributes to sustainable plastic management practices, aligning with the broader goal of mitigating plastic pollution and promoting a more environmentally conscious approach.

Protective helmets are used in a wide range of professional, sport and recreational activities. They undoubtedly play a very important role in the prevention of head injuries, including traumatic brain injury. There is no doubt that they improve user safety. The main aim of the following paper is to analyse recent publications and studies describing to what extent a helmet can protect against traumatic brain injury and its consequences. Traumatic brain injury is the disruption of brain function or the presence of any other pathology in the brain caused by physical force. There are many head injuries worldwide that result in traumatic brain injury. The effects of these accidents can be reduced by using safety helmets. Statistics quite clearly show that helmets realistically reduce the number of traumatic brain injuries, as well as their consequences. Injuries sustained by people who wore a helmet on their head at the time of the accident were less severe, gave less serious complications and were also less likely to be fatal compared to injuries acquired when a helmet was not worn on the head. The wearing of helmets has been made compulsory in many places and this has had a significant impact on the decrease in the incidence of severe brain injuries. The use of protective helmets is correlated with milder and less frequent head injuries and fewer complications of these injuries. Public awareness of traumatic brain injury is still low. Although the benefits of wearing helmets are widely known, there are still many people who do not use this method of head injury prevention. Awareness campaigns, notification systems or other innovative methods are just a few of the many ways in which attempts are made to draw the public’s attention to the need to wear a helmet during activities with a higher risk of head injury.
Training load as the conditioning of vertebral column dysfunction in road cyclists
Authors: Sawicka Marta
Published: January 2024

Background. Spinal dysfunctions pose significant problems for road cyclists as they affect their efficiency and the quality of life. Despite this,fact only few studies are focused on the effect of training on the aforementioned dysfunctions. This gap in literature is even bigger as far as competitive/professional road cycling is concerned, despite the significant load the competitors are exposed to. This study is focused on understanding how different components of training load affect dysfunction of the vertebral column in road cyclists, both competitive and amateur ones. Additionally, the thesis how the program of adequate bioregeneration can contribute to reduction of spinal dysfunction risk is analyzed. Material and methods. The samle included 60 cyclists. The participants were divided into two groups: 30 competitive road cyclists UCI World Tour (first division) and 30 amateur road cyclists. The aim of the study was to understand the effect of different components of training load on the on the origin of spinal dysfunction in road cyclists . A questionnaire including the questions concerning personal data, the length of the road cyclist’s training period, training load, complementary training as the frequency and location of back pain, and also the questions, as the questions focused on information on the sustained injuries and contusions as well as as the access and the quality of the physiotherapeutic procedure. Results. The study using statistical tools revealed that many aspects of training affect vertebral column dysfunction in road cyclists, both competitive and amateur ones. The results also suggest that both professional and amateur cyclists should pay more attention to prevention and treatment of back pain. These procedures may involve regular workouts strengthening and stabilizing the vertebral column, control of training load as well as regular assessment by a physiotherapist. However, it was impossible to develop a concrete mathematical pattern for prognosing the aforementioned dysfunctions. Conclusion. The study provides new information on the training record in cyclists on the prevalence of back pain in road cyclists. The study found significant differences between the analyzed variables, however, in no case, the designated linear regression function allowed description of these relationships. This may indicate that the relationships are more complicated than it is suggested based on a simple linear model or that there are other factors responsible for back pain, which were not taken into consideration in this model. Further research using more complex regression models or taking into consideration additional variables are required for better understanding of the factors affecting vertebral column dysfunction in road cyclists – it will be the subject of further research by the authors.
