Developments in Gari Production | Chapter 04 | Research and Development in Agricultural Sciences Vol. 1

Aim: The aim of this study was to evaluate the effect of Lactobacillus plantarum 1 on the Sensory Attributes and Proximate Composition of gari made from Manihot esculentum Crantz.

Study Design: Freshly harvested mature cassava was peeled and grated. This was further divided into two equal parts to represent samples (W) and (Wo). Sample (W) was inoculated with pure strain of Lactobacillus plantarum 1, while sample (Wo) was not inoculated. The two samples of dough were poured into different jute bags and allowed for 96 hrs to ferment and dehydrate. The resulting dough was sieved and roasted for 30 minutes.

Methodology: Sensory attributes were evaluated using the Hedonic Rule which involved a panel of seven judges, while proximate composition of gari samples was determined using standard methods. The data obtained were analysed using T-test.

Results: The results from this study showed that the score for the sensory attributes for sample (W) was significantly higher (P<0.05) compared to sample (Wo). On the other hand, the proximate analysis showed that moisture content, ash, fat, protein and fibre were significantly higher (P<0.05) in sample (Wo) compared to sample (W).

Conclusion: In conclusion, it can be deduced that using L. plantarum 1 in cassava fermentation improved all sensory attributes evaluated in this study. In addition, the study further revealed that traditional fermentation yielded gari with higher nutritional values.

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...

There is No Standard Model of ZFC and ZFC2 | Chapter 03 | Advances in Mathematics and Computer Science Vol. 1

In this Chapter we obtain a contradictions in formal set theories under assumption that these theories have omega-models or nonstandard model with standard part. An possible generalization of Lob’s theorem is considered. Main results are: (i) ¬Con(ZF C+ ∃ M ZFC st ), (ii) ¬Con(N F+ ∃ M NF st ), (iii) ¬Con(ZF C 2 ), (iv) let k be an inaccessible cardinal then ¬Con(ZF C+ ∃ κ), (v) ¬Con(ZF C+ (V=L)), (vi) ¬Con(ZF+ (V=L)).

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...
