Influence of Microorganisms on Corrosion Induction and Protection | Chapter 03 | Advances and Trends in Biotechnology and Genetics Vol. 1

The microbial corrosion or the microbiologically induced corrosion (MIC) is defined as the deterioration of metals as a result of metabolic activities of microorganisms. MIC leads to important economical losses in many industries and services. Anaerobic Sulfate-reducing bacteria (SRB) is a serious type of MIC commonly found in the oil and gas industry sector and are responsible for most highly corrosion damages to offshore steel structures. The SRB present in the crude oil uses the sulfate as an electron acceptor generating corrosive hydrogen sulfide (H2S) as one of their products. Other types of MIC are the aerobic iron and manganese bacteria mainly responsible about the accelerated pitting attacks of stainless steel. Most MIC takes the form of pits that form below the colonies of living organic matter and mineral and the deposits of biological origin. The most affected devices by MIC are stainless and carbon steel tanks, pipelines, heat exchangers, fuel storage tanks. On the other hand, many beneficial bacteria, (such as Bacillus lichiniformis) have the ability to protect metal surfaces from corrosion via different mechanisms including biofilms and formation of sticky protective layer of γ-poly-glutamate or antibiotics on metal surfaces. The aim of the present work is to present a spotlight on the history and the role of microorganisms in corrosion induction and prevention. This chapter includes corrosion inhibition mechanisms employing beneficial microorganisms with special reference to microbial biofilms to avoid the dramatic economic loss due to corrosion. On the contrary, different types of harmful microorganisms included in corrosion are also discussed including iron and sulfur reducing bacteria.

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...
