The high level of noise that radiates from domestic generators in most parts of the neighbourhoods in Nigeria is becoming very much uncomfortable and constitutes nuisance to public serenity thereby creating noise pollution.This paper reports the design and performance evaluation of a soundproof enclosure for a 2.5 kVA generator.The purpose of this
Digital control systems are well established in many industries and could find application in the wine sector.Of critical importance to red wine quality, the efficient and targeted extraction of polyphenols from red grape solids during alcoholic fermentation could be a focus for automation.Smart technologies such as model predictive control (MPC) o
To Hair Accessories study the dynamic characteristics and microstructure of nano-CaCO3 remolded soft clay under cyclic loading, GDS dynamic triaxial and NMR tests were conducted to analyze its dynamic stress-strain, dynamic elastic modulus, damping ratio, and micro pore changes.The results show that as the content of nano-CaCO3 increases and the co
Shrimp aquaculture wastewater after the end of the rearing period has a high total 10/10N organic matter (TOM) content of up to 87.74 mg/L.If the wastewater is disposed of directly without any efforts to reduce or treatment, it will disturb public waters ecosystem because of the high organic matter.The aim of this study was to determine the rate of
