Unbalance and Vibration of High-Speed Sewing Machine (Part I. Unbalance)
Journal of the Japan Society of Precision Engineering, 1959 Unbalance and vibration of a Japan-made sewing machine (DDW-Type) were studied. Both the needle and its holder of this machine move up and down in its running condition, and therefore they produce unbalane force in its vertical direction. This unbalance force may, however, be cancelled by attaching a certain balance weight to its mainshaft, but by this

Aerospace, 2022 An aero engine fan rotor is composed of a multi-stage disk and multi-stage blades. Excessive unbalance of the aero engine fan rotor after assembly is the main cause of aero engine vibration.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Identification of Rub and Unbalance in 320-MW Turbogenerators [PDF]
The International Journal of Rotating Machinery, 2003 This article presents two experiences of applying a model‐based fault‐identification method to real machines. The first case presented is an unbalance identification in a 320 MW turbogenerator unit operating in a fossil power plant. In the second case, concerning a machine of the same size but from a different manufacturer, the turbine has been ...

FEBS Letters, EarlyView.Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Active Magnetic Bearings for Frictionless Rotating Machineries [PDF]
, 2006 Active magnetic bearing (AMB) systems can support a rotor without physical contact and enable users to precisely control rotor position and vibration as function of time or other parameters.
