Changes of Microbial Community in the Irrigative Grey-Brown and Grey-Meadow Soils under Vegetable Cultures of Dry Subtropical Zone | Chapter 08 | Advances and Trends in Agricultural Sciences Vol. 2

Introduction: Soils contain a very high, but mostly unknown biodiversity, and soil biology remains an under studied topic. Soil organisms are a key factor for soil development and in turn depend on soils as a habitat. Microorganisms carrying out metabolic processes remove nutrients from the ecosystem and use them to build new cells. Microorganisms are the backbone of all ecosystems. Microbes are decomposers, with the ability to recycle nutrients from other organisms' waste products.

Aims: The objective of this study was to examine the distribution of microorganisms in different types of agricultural soils.

Study Design: Comparative analysis of quantity of microorganisms in a crop rotation and constant (permanent) in a dry subtropical zone in different types of soils.

Methodology: Microorganisms quantity has been defined by (microorganisms total quantity meat-peptone-agaric (MPA) and starchy-ammoniac-agaric (SAA), actinomycetes starchy - agaric- agaric (SAA) and microscopic fungus quantity have been defined on Chapek agaric environment on the basis of the method received in the Institute of Microbiology of Moscow.

Results: The results showed that the quantity of microorganisms in a crop rotation was more, than permanent cultivation of these cultures. A mineralization of organic substances in soils under constant cultures occurred more intensively, than in a crop rotation.

Conclusion: Including in a crop rotation of legume cultures (Lucerne, haricot, bean) increases quantity of microorganisms, also slows down intensity mineralization of organic substances. This study showed that the soil microbial metabolic functional diversity had high variability. The number of bacteria in the irrigated meadow-serozemic soils was smaller than in the gray-brown soils, and the number of actinomycetes was on the contrary higher in the grey-brown and meadow-serozemic soils. The meadow-serozemic soils were characterized by the maximal intensity of the mineralization of the plant residues among the studied soils.

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...

Occipital Dermal Sinus Tract Causing Craniospinal Infection: A Review | Chapter 13 | New Visions in Medicine and Medical Science Vol. 4

  Dermal sinus is a rare congenital condition characterized by a pathological tract connecting the skin to deeper tissues of the central nervous system, potentially leading to severe infectious complications. It arises from a failure in the separation of ectodermal layers during early gestation. Diagnosing dermal sinus tract in newborns requires a careful physical examination, focusing on midline dimples in the occipital region associated with cutaneous abnormalities like hairy nevus or hyperpigmentation. The presence of drainage, abnormal hair distribution, or localized swelling may indicate a sinus tract. Regular examination for dimples or sinuses is recommended for infants and children with recurrent meningitis or infections. Early detection is crucial to prevent severe complications like meningitis, with Staphylococcus aureus being a common causative organism. Neuroradiological studies, including computed tomography (CT) scan and magnetic resonance imaging (MRI), with histopath...

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...
