Interrelationship and Cause - Effect of Morphological Traits with Grain Yield and Oil Content among Indian Mustard (Brassica juncea L. Czern & Coss) Genotypes under Non- irrigated and Irrigated Condition | Chapter 11 | Advances and Trends in Agricultural Sciences Vol. 2

Water scarcity is a venomous upshot of climate change and is one of the sternest factors restraining global crop productivity. In order to study association and cause-effect of shortage in irrigation on some morphological and quality traits on yield, an experiment accommodating 20 genotypes of Indian  mustard (Brassica juncea L. Czern & Coss), was conducted in Randomised Complete Block Design (RBCD) from various Rapeseed & Mustard centres  located across country, randomly in three replications  during Rabi 2016-17, one condition subjected to drought (devoid of irrigation) inside  the Rainout shelter under residual moisture condition and another situation with  normal irrigated field condition at research farm of Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur. Genotypic correlations for grain yield and other characters were invariably higher than phenotypic correlations indicating indicated less influence of environment. Earliness in flowering (-0.010; -0.256) and maturity (-0.335; -0.185), Secondary branches per plant (0.267; 0.169), Siliqua on primary mother axis (0.162; 0.079), Length of primary axis (0.006; 0.275), Siliqua density (0.244; 0.189) and Biological yield (0.444*;0.411*) also had shown positive correlation with grain yield per plot at phenotypic level under both non- irrigated and irrigated condition indicated that improvement in these morphological parameters indicated genotypes with early flowering and maturity coupled with more secondary branches with  more siliqua accommodated by longer primary mother axis with increasing density of siliqua along with high biological yield and will ultimately enhance the grain yield.

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...

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...

Risk Factors for Postpartum Psychiatric Disorders. A Review of the Literature | Chapter 8 | New Visions in Medicine and Medical Science Vol. 4

  Objective: The aim of this study was to explore the risk factors for the development of postpartum psychiatric disorders through international literature. Materials and Methods: Throughout many articles in PubMed, Google scholar and PsycInfo, a great amount of recent data was gathered to identify the disorders that are most common as well as their risk factors. Results: After childbirth, most commonly women experience postpartum depression, anxiety disorders, post-traumatic stress disorder and postpartum psychosis. All the disorders have many similar risk-factors with the main one being preexisting psychiatric disorder and many similar symptoms too. Conclusions: Women after childbirth are at risk of experience many psychiatric disorders, such as postpartum distress, postpartum post traumatic stress disorder and even more rarely postpartum psychosis. It is important to provide comprehensive support to ensure the well-being of both the mother and the infant and this will b...
