Nematicidal Efficacy of Fluensulfone against False Root-knot Nematode (Nacobbus aberrans) in Cucumber Crop under Field Conditions | Chapter 10 | Advances and Trends in Agricultural Sciences Vol. 2

The present study was carried out to compare the efficacy of a nematicide of new generation for the control of the false root-knot nematode; Nacobbus aberrans, in cucumber crop (Cucumis sativus L.) under field conditions. The experiment was set up under a randomized complete block design with four replications. Six treatments were assessed for control of N. aberrans: four doses of fluensulfone, one of the nematicide oxamyl and a control with no application of nematicides. Ten days before transplanting, nematicides were applied in a single application via irrigation systems. Higher control under field conditions was obtained with the application of fluensulfone at a dose of 2.75 L.ha-1. The lowest final population densities of N. aberrans in cucumber crop were recorded in the plots treated with fluensulfone at the dose of 2.25 L.ha-1, with an average of 6.25 juveniles, and the lowest galling index was observed in plots treated with fluensulfone at the same dose, with a galling index of 2.1. The results indicated that application of fluensulfone to cucumber crop can provide good control of N. aberrans.

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...
