Lebesgue Measure Preserving Thompson Monoid and Its Properties of Mixing, Periodic Points and Entropy | Chapter 03 | Innovations in Science and Technology Vol. 7

 This work defines the Lebesgue measure preserving Thompson monoid, designated by G, which is similar to the Thompson group F except that its members retain the Lebesgue measure and can be non-invertible. The work investigates the mixing qualities of G, periodic points, and entropy. To be more specific, we show that for each element of G, topological mixing (TM) is identical to locally eventually onto (LEO), and that the elements of G with LEO are dense in the set of continuous measure preserving mappings. Following that, we demonstrate that every dyadic point is preperiodic and that any map in G is Markov. We show that periodic points with period 3 exist for maps in a subset of G, which is a fundamental feature of chaotic maps, and we characterise the periods of periodic points in other maps in G. Finally, we prove that in the set of continuous measure preserving maps, the elements of G that are Markov LEO maps and whose entropy values are arbitrarily close to any number larger than or equal to 2 are dense.

Greening Regional Airports: A Vision for Carbon Neutral Infrastructure | Chapter 12 | Contemporary Perspective on Science, Technology and Research Vol. 3

 This study provides an overview of the energy demand of a regional airport, divided into individual time horizons. The electrification of aircraft systems raises the question of whether airports will be among the largest electricity consumers in our infrastructure in the future. Sustainability and especially emission reductions are significant challenges for airports that are currently being addressed. The Clean Sky 2 project GENESIS addresses the environmental sustainability of hybrid-electric 50-passenger aircraft systems in a life cycle perspective to support the development of a technology roadmap for the transition to sustainable and competitive electric aircraft systems. This article originates from the GENESIS research and describes various options for ground power supply at a regional airport. Potential solutions for airport infrastructure with a short (2030), medium (2040), and long (2050) time horizon are proposed. In addition to the environmental and conservation benefi...

Alkali Element Modification of Glucose Molecules as a Method to Dissolve Cancer Cells | Chapter 12 | New Visions in Medicine and Medical Science Vol. 4

  The present study highlights about alkali element modification of glucose molecules as a method to dissolve cancer cells. The central regulation of the mechanisms governing cell proliferation has little effect on cancer cells. Cancer cells are entirely independent of the central command and divide and proliferate on their own, making it challenging to activate their response mechanism. Precisely, this is the reason why they are at risk to the health of humans and/or any biological entities. Instead of trying to reconnect the central command of the growth control mechanism to cancer cells that are already out of the range, we present a method of using the cancer cell’s own irresponsive and uncontrolled growth mechanism to their disadvantage and destroy the cancer cells. We found that this is achievable in an atomic/molecular level study of the glucose molecule, which is the primary food source used for growth and energy generation by all cells in the body, including the cancer cel...

Diagnosis and Management of Scrapie in Post Mortem Goats by Immunohistochemistry | Chapter 6 | New Visions in Medicine and Medical Science Vol. 4

  The main objective of this study was to contribute to the annual passive surveillance for this pathology, since the goats are a species considered reservoir for the prion. A class of pathologies known as Transmissible Spongiform Illnesses (TSEs), which affect both humans and animals, includes scrapie, a neurological disease with a slow and deadly course that affects sheep, goats, and mouflons. Given that Immunohistochemistry (IHC) is the globally accepted technique for identifying classical scrapie in goats—a species thought to be a potential zoonotic disease reservoir. Chile in relation to Bovine Spongiform Encephalopathy (BSE), is classified as a disease-free country. Scrapie is actively monitored for the sheep, but passively for the caprine species, which is why this study was carried out in slaughtered goats in the central north of the country (IV Region), to provide information to the surveillance system for this disease. Fifty brains of goats older than 2 years were used, r...
