This study provides a novel methodology for the natural frequency estimation of the jet engine turbine blade by using the dimension check.This paper presents a summarization of the ongoing research devoted to the method for the turbine blade natural frequency estimation.The main target of the research presented in the paper is to develop a novel me

In the current investigation, a multi response optimization technique based on Taguchi method coupled with Grey relational analysis is planned for wire-EDM operations on ballistic grade aluminium alloy for armour applications.Experiments have been performed with four machining variables: pulse-on time, pulse-off time, peak current and spark voltage

Moroccan forest ecosystems are rich in biodiversity.However, they are threatened by deforestation.To reduce this, the country has adopted plans involving reforestation.This study compares the diversity of saproxylic litter beetles in two forests in the province of El Jadida, Morocco: the natural Haouzia matorral and the reforested Chiadma forest.Th

Bacterial communities play an important role in maintaining stable functioning of soil ecosystems, participating in decomposition of plant residues, accumulation of organic matter, formation of soil aggregates and in the cycle of nutrients.For Umbrella Cover agroecosystems, maintaining the diversity of microbiocenosis is especially critical because
