An Advanced Study on Sound Sources in Turbulent Jets | Chapter 1 | Current Topics on Mathematics and Computer Science Vol. 8

In order to better understand acoustic regimes in turbulent jets, a spatio-temporal velocity correlation analysis of aerodynamic flow was performed. Acoustic source regions are regarded as moving and fixed in space, respectively, when flow characteristics are evaluated in Lagrangian and Eulerian modes, conscious of their uniqueness. The space-time energy spectrum was used to generate correlation coefficient functions that might be used to forecast sound inside an acoustic zone. It is discovered that expressing the Eulerian turbulent velocity field in the similitude of a Fourier series yields the autocorrelation function of a particular time-bound spatial Fourier element.

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...
