Combining Ability Analysis for Grain Improvement in Linseed (Linum usitatissimum L.) | Chapter 05 | Emerging Issues in Science and Technology Vol. 1

Eight diverse parents of linseed (Linum usitatissimum L.) were used in diallel mating design (excluding reciprocal) to generate twenty eight crosses and evaluated against Shekhar as check in randomized block design for nine quantitative traits. General combining ability (GCA) of the parents and specific combining ability (SCA) of crosses were estimated for development of high yielding varieties. Analysis of variance revealed that the genotypes differed genetically from each others for all the nine characters studied. Combining ability analysis revealed that mean square due to GCA and SCA for days to 50% flowering, days to 50% maturity, plant height, number of primary branch, number seeds per capsules, oil percent and grain yield were significant. Genetic component of variances depicted that additive genetic variance were higher than non-additive genetic variance for plant height, number of capsules per plant and oil percent. Whereas, non-additive genetic variance was higher for rest of the characters studied. SLS72 was found to be good general combiner for grain yield and its attributing traits viz. Oil percent, number of capsules per plant, shorter plant height and early flowering. Crosses PKDL71 x LCK7035, NL260 x SLS72, NL260 x Shekhar, RL26018 x Shekhar, LCK7035 x BAU-06-05 and RL26018 x LCK7035 showed higher positive significant SCA effects for grain yield per plant.

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...
