Rapid and Mass Propagation of Hybanthus enneaspermus (L.) F. Muell. from Shoot Tip and Nodal Explants | Chapter 11 | Modern Research in Botany Vol. 1

A rapid and efficient protocol for in vitro propagation of Hybanthus enneaspermus (L.) F. Muell. (Violaceae) has been developed from the shoot tip and nodal explants. The explants were cultured on MS basal medium supplemented with different concentrations of cytokinins, viz., BAP and Kin, ranging from 5 µM to 25 µM, either individually or in combinations of both these cytokinins for shoot induction. Shoot buds of both the explants proliferated on MS medium supplemented with both cytokinins. The best response was observed on MS medium containing 15 µM BAP. Subsequently the optimum concentration of BAP (15 µM) was combined with different concentrations of Kin ranging from 2 µM to 10 µM. Maximum number of 28.6 ± 0.90  and 36.8 ± 1.54 shoots were produced on MS medium containing 15 µM BAP + 6 µM Kin from the shoot tip and nodal explants respectively. The regenerated shoots were transferred to rooting medium containing auxins at different concentrations ranging from 2 µM to 10 µM of IAA, IBA or NAA. The highest number of roots were observed on half strength MS medium fortified with 4 µM IBA. The plantlets were then hardened and acclimatized in soil. About 80% of plantlets were survived in the field condition. A completely randomized design was used in all experiments and analysis of variance and mean separations were carried out using Duncan’s Multiple Range Test.  Each treatment factor consists of 10 replicates repeated for 5 times. This protocol would help ex situ conservation of this medicinal 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...

There is No Standard Model of ZFC and ZFC2 | Chapter 03 | Advances in Mathematics and Computer Science Vol. 1

In this Chapter we obtain a contradictions in formal set theories under assumption that these theories have omega-models or nonstandard model with standard part. An possible generalization of Lob’s theorem is considered. Main results are: (i) ¬Con(ZF C+ ∃ M ZFC st ), (ii) ¬Con(N F+ ∃ M NF st ), (iii) ¬Con(ZF C 2 ), (iv) let k be an inaccessible cardinal then ¬Con(ZF C+ ∃ κ), (v) ¬Con(ZF C+ (V=L)), (vi) ¬Con(ZF+ (V=L)).

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...
