Hydro-Fracture Resistance Properties of Hura crepitans Seed Relevant to Handling and Processing | Chapter 08 | Current Trends in Food Science Vol. 1

During harvesting, handling and dehulling, agricultural materials including seeds were subjected to several static and dynamic pressures that may affect the quality of the kernel if not properly handled. This work therefore studied the effects of moisture content on some compressive properties of Hura crepitans as a preparation for the design of the seed dehulling machine. Hura crepitans seeds were conditioned to four different moisture contents (9.3, 12.6, 15.6, and 17.8% db). The effect of moisture contents on energy at yield, energy at break, compressive load at yield, compressive load at break, compressive strain at yield and at break and compressive stress at yield and at break were studied using Instron testing machine (Model 3369). The results of the experiment show an increase in load at break from 44.87 to 356.27N; Load at yield from 10.87 to 83.06 N; and decrease in energy at yield from 0.262 to 0.021J; energy at break from 2.292 to 0.258 J; compressive strain at yield from 0.311 to 0.160 mm/mm; compressive stress at break from 2.809 to 0.384 mm, with increase in moisture in the range studied. The effect of moisture content on all the properties studied were significant (p> 0.05). These result showed that the compressive force properties of Hura crepitans is moisture dependent. The data reported in this work will be of great help during the design of Hura crepitans seed harvester, dehuller, cleaning and sorting equipment for the seed.

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...
