Tolerance Potential of Selected Genotypes of Zea mays L. and Pennisetum glaucum (L.) R. Br. under Drought Stress | Chapter 01 | Modern Research in Botany Vol. 1

Three genotypes of Pennisetum glaucum (IP14599, IP14787and LRNO3) and Zea mays (DTSYN11, LRNO1 and LRIO1) were screened at specified periods of drought stress and evaluated to detect trait signals for drought tolerance. Specific responses were confirmed against drought among all the selected genotypes of both the species. Genotypes of P. glaucum showed high biomass production, increased tolerance index and high plant nutrient content during drought stress. Conversely, genotype DTSYN11 of Z. mays performed better than the LRNO1 and LRIO1 regarding the evaluated traits. Biochemical studies related to protein content, proline, MDA concentration and antioxidants (CAT, APX) accumulation in both the species highlighted that pearl millet genotypes are better adapted than maize under drought stress. The low concentration of MDA and high accumulation of antioxidant enzymes were observed during increased duration of stress, perhaps this provides some extent of osmotic protection and antioxidant defence modulation to the pearl millet genotypes, thus causing protection to the crop. This work explains the capacity of pearl millet related to the defence mechanism over the maize genotypes under drought condition. Hence, pearl millet would be of great relevance in breeding programmes for crop improvement and can serve as a valued reserve to explicate molecular strategies in manipulating drought tolerance to other susceptible crops.

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...

Study on Processing Method Influences the Effect of Cassava (Manihot esculenta) Consumption on Blood Lipid Profile in Rats | Chapter 8 | Current Research and Development in Chemistry Vol.1

Cassava is consumed in many tropical countries and is fast becoming the major raw material of many diets, especially in the bakery, brewery and pharmaceutical industries. In a study to determine the effects of various formulations of Cassava feeds on blood lipid profile in rats. Forty adult Wistar rats weighing between 120 and 150 g were divided into 4 groups of 10 rats each. The rats were acclimatized for one week; fed with different formulations of Cassava feeds adlibitum, after which the rats were allotted into groups. Group 1 was fed on Garri; group 2 on Cassava flour; group 3 on Tapioca, and the control group (group 4) on normal chow. After 4 weeks, each animal was anaesthetized by exposure to chloroform vapour and blood samples collected by cardiac puncture. Group 1 diet (Garri) significantly increased HDL-cholesterol (HDL-C) concentration and significantly decreased LDL-cholesterol (LDL-C) concentration (p<0.05) compared with the control group. In Group 2 (Cassava flour), t...

Ethnopharmacological Survey among Traditional Medicine Practitioners in Abidjan (Côte d'Ivoire) for the Management of Pathologies such as Malaria, ENT Diseases, Diarrhea, Typhoid Fever and Anemia | Chapter 05 | New Horizons in Medicine and Medical Research Vol. 8

 Traditional Medicine Practitioners (TMPs) of Côte d'Ivoire are familiar with the therapeutic herbs. Medicinal plants have been shown to be useful in the treatment of common diseases such as malaria (KROA, 2004) and diabetes (N'GUESSAN et al, 2013) in several studies and scientific study. In the Abidjan District, the current policy is to integrate traditional medicine and pharmacopoeia into the national health system in order to improve population health coverage, particularly in the management of commonly encountered diseases such as malaria, ENT diseases, diarrhoea, typhoid fever, and anaemia. This research aims to increase the use of traditional medicine and pharmacopoeia in the national health system. Over the course of three months, fifty (50) PMTs in the District of Abidjan participated in this study. Plant therapists accounted for 30 of the 50 PMTs polled at the end of the study, or 60%. Traditional medicine centres use 61 types of medicinal plants from 36 famili...
