The strapdown inertial navigation system (SINS) can be installed on a shearer and used for monitoring its position.However, under the complex environment of the mechanized mining face, the strong vibration of the shearer may cause large calculation error.First, the dynamic model of a double-drum shearer is built with a force analysis, and the spect
In this work we investigate the rheological behaviour of macroscopic buoyant hard spheres dispersed in a shear-thinning suspending fluid.We focus on the phenomenological study of the influence of the shear-thinning behaviour of the suspending medium on the effective apparent suspension viscosity at different volume fractions.In the oil industry, th
This article presents our research results on the physical-chemical and direct injection diesel engine performance parameters when fueled by pure diesel fuel and retail hydrotreated vegetable oil (HVO).This fuel is called NexBTL by NESTE, and this renewable fuel blends with a diesel fuel known as Pro Diesel.A wide range of pure diesel fuel and NexB
Heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar) was first diagnosed in Norway in 1999.The disease is caused by Piscine orthoreovirus-1 (PRV-1).The virus is prevalent in farmed Atlantic salmon, but not always associated with disease.Phylogeny and sequence analyses of 31 PRV-1 genomes collected over a 30-year per
