Modelling and Simulation of a New Variable Stiffness Holder for Milling of Flexible Details

open access: yesPolish Maritime Research, 2017
Modern industry expectations in terms of milling operations often demand the milling of the flexible details by using slender ball-end tools. This is a difficult task because of possible vibration occurrence. Due to existence of certain conditions (small

Effects of Lycium barbarum Residue Substituting Dietary Maize on Fecal Microbiota and Growth Performance of Crossbred Simmental Cattle

open access: yesAnimal Research and One Health, Volume 4, Issue 3, Page 335-346, August 2026.
The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased

Insects and Survival: A Review of Primary and Secondary Defense Strategies

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Disturbance‐Resilient Voltage/Power‐Quality Management for Islanded Inverters Using Self‐Tuning Type‐3 Fuzzy Controller

open access: yesEnergy Science &Engineering, Volume 14, Issue 6, Page 2816-2838, June 2026.
An adaptive fuzzy controller using an interval type‐3 fuzzy logic system replaces the SMC switching term to mitigate chattering while preserving global stability for islanded inverters. Simulations show lower THD, greater robustness to disturbances and parameter variations, and improved voltage‐tracking accuracy, with applicability to other uncertain ...

MODEL AND EXPERIMENT OF THE HYSTERIS CHARACTERISTICS ON MAGNETORHEOLOGICAL DAMPING LATHE TOOL

open access: yesJixie qiangdu, 2016
Cutting chatter is one of the major problems which constraints the high-performance and high-precision of the machining products. A damping lathe tool based on intelligent material — magnetorheological fluid was developed in order to effectively suppress

Design of Chatter-Resistant Damped Boring Bars Using a Receptance Coupling Approach

open access: yesJournal of Manufacturing and Materials Processing, 2020
Deep hole boring using slender bars that have tuned mass dampers integrated within them make the boring process chatter vibration resistant. Dampers are usually designed using classical analytical solutions that presume the (un)damped boring bar which ...

Red era: Dyeing yak hair fibres red with in situ generated silver nanoparticles using silver nitrate and a flavonoid‐containing plant extract

open access: yesColoration Technology, Volume 142, Issue 3, Page 439-455, June 2026.
Abstract Plants and their extracts have been used for dyeing fabrics, skin and hair for thousands of years and have been experiencing a revival in the last years due to increasing health risks arising from oxidative hair dye precursors. We developed a novel two‐step method to dye keratin fibres based on in situ formed silver nanoparticles including a ...
