Evaluation of Buffer Lime Requirement Methods without Hazardous Chemicals for Acid Soils of Assam, India | Chapter 06 | Research and Development in Agricultural Sciences Vol. 1

Liming is one of the most important and feasible management practices used to ameliorate soil acidity. The amount of lime required to neutralize the soil acidity is called lime requirement. Generally lime requirement (LR) for acidic soils are determined by buffer pH method because of their ease of implementation, simplicity and rapidity (Wolf el al., 2008). The SMP buffer test is used to determine lime requirement for Assam soils. Though this method is proven to work for Assam soils, it uses p-nitrophenol, which is very hazardous substance. Now-a-days soil-testing laboratories are under increasing pressure to reduce hazardous waste. So goal of this study was to evaluate a buffer as alternatives to the SMP buffer in determining the LR for Jorhat soils. In this study three buffer methods were used, i.e., Shoemaker, McLean and Pratt buffer; Sikora-I buffer and Sikora-II buffer. Further, Sikora-II based on the analysed parameters may be considered as an alternative to present SMP buffer lime requirement method. These findings may overcome the use of hazardous chemicals used for recommending lime rate during Soil Health Card (SHC) preparation as mandated by Govt. of India.

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...
