Hydro-Fracture Resistance Properties of Hura crepitans Seed Relevant to Handling and Processing | Chapter 08 | Current Trends in Food Science Vol. 1

During harvesting, handling and dehulling, agricultural materials including seeds were subjected to several static and dynamic pressures that may affect the quality of the kernel if not properly handled. This work therefore studied the effects of moisture content on some compressive properties of Hura crepitans as a preparation for the design of the seed dehulling machine. Hura crepitans seeds were conditioned to four different moisture contents (9.3, 12.6, 15.6, and 17.8% db). The effect of moisture contents on energy at yield, energy at break, compressive load at yield, compressive load at break, compressive strain at yield and at break and compressive stress at yield and at break were studied using Instron testing machine (Model 3369). The results of the experiment show an increase in load at break from 44.87 to 356.27N; Load at yield from 10.87 to 83.06 N; and decrease in energy at yield from 0.262 to 0.021J; energy at break from 2.292 to 0.258 J; compressive strain at yield from 0.311 to 0.160 mm/mm; compressive stress at break from 2.809 to 0.384 mm, with increase in moisture in the range studied. The effect of moisture content on all the properties studied were significant (p> 0.05). These result showed that the compressive force properties of Hura crepitans is moisture dependent. The data reported in this work will be of great help during the design of Hura crepitans seed harvester, dehuller, cleaning and sorting equipment for the seed.

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...
