Effect of Date of Sowing and Topping on Seed Production of Jute in Red and Laterite Zone of West Bengal | Chapter 09 | Advances in Applied Science and Technology Vol. 6

Aim: To assess the effects of date of sowing and topping on seed production of tossa and white jute.

Design: Split plot.

Place and Duration of Study: Field experiment was conducted during Kharif season of 2014 and 2015 at Regional Research Sub-station, Raghunathpur, Bidhan Chandra Krishi Viswavidyalaya, Purulia, West Bengal, India.

Methodology: Two separate experiments were carried out on tossa jute, Corchorus olitorius L.(cv. JRO-8432) and white jute, Corchorus capsularis L. (cv.JRC-698), each having 3 replications, with 3 main plots of dates of sowing (D1-15th June, D2-15th July and D3-15th August) and 4 sub plots for topping treatments [T1-No topping, T2-Topping at 30 Days After Sowing (DAS),T3-Topping at 45 DAS and T4-Topping at 60 DAS] under rainfed condition.

Results: In both the jute varieties, the first date of sowing (15th June) proved superiority over other sowing dates irrespective of topping, however, topping at 45 DAS revealed best results as compared to other topping treatments in both the years. First date of sowing (15th June) along with topping at 45 DAS (30th July) recorded the highest number of primary branches plant-1, number of pods plant-1 and the highest seed yield which contributed to significantly higher gross and net return in both the varieties in both the years of experimentation.

Conclusion: Early sowing i.e. around 15th June and topping at 45 DAS could be recommended for enhancement of total seed production in olitorius as well as capsularis jute in red and laterite zone of West Bengal.

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...
