Stresses Analysis on Spur Gear for Different Contact Ratio [PDF]
, 2019 This paper concentrated on the effect of contact ratio on the contact stresses generated on meshing spur gear teeth during the power transmission. In this study, various contact ratios of spur gear teeth have been analyzed.

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Effects of surface defects on rolling contact fatigue of 60/40 brass [PDF]
, 1999 A study into effects of surface defects on rolling contact fatigue of 60/40 brass under a maximum contact pressure of 600 MPa and a slide–roll ratio of ?1% was undertaken on a twin-disc rolling–sliding test machine.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Finite element modelling and load share analysis for involute worm gears with localised tooth contact [PDF]
, 2001 A new approach has been developed by the authors to estimate the load share of worm gear drives, and to calculate the instantaneous tooth meshing stiffness and loaded transmission errors. In the approach, the finite element (FE) modelling is based on the

Patterns of simultaneous contact allergies in patients with contact sensitization to oxidised linalool and oxidised limonene [Elektronisk resurs] [PDF]
BACKGROUND: Contact allergy rates of linalool and limonene hydroperoxides (HPs) have increased. OBJECTIVES: To demonstrate the patterns of simultaneous positive patch test (PT) reactions and prevalences of multiple contact allergies (MCAs) in patients ...

Effect of contact angle and helix angle on slide-roll ratio under the uniform motion state of BSM
MATEC Web of Conferences, 2017 To study the effect of contact and helix angles on slide-roll ratio at the ball contact point under the uniform motion state of ball screw mechanism (BSM), a slide- roll ratio model was derived in the literature [9] were used in this paper.

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

Mediating variables in the relationship between 2D: 4D digit ratio and sports achievement rank [PDF]
, 2004 This study investigated the extent to which 2D: 4D digit ratio, mental rotation ability and the personality variables of social-potency, achievement, harm-avoidance and control are effective predictors of achievement rank in team sports and also whether ...
