Critical points and magnitude of impacts on the packing line: effect on ripening and quality of 'Packham's Triumph' pears

open access: yesSemina: Ciências Agrárias, 2017
Pears have a very sensitive epidermis and are prone to signal mechanical blemishes, which result in reduced visual quality and low consumer acceptance.

Lateral tyre forces on off-road surfaces [PDF]

open access: yes, 1988
A successful model for off-road tyres must be reliable, efficient and capable of reproducing and predicting the main system phenomena. Mathematical models are proposed for longitudinal, lateral and combined lateral and longitudinal force generation ...

Simulation of the deflected cutting tool trajectory in complex surface milling [PDF]

open access: yes, 2011
Since industry is rapidly developing, either locally or globally, manufacturers witness harder challenges due to the growing competitivity. This urges them to better consider the four factors linked to production and output: quality, quantity, cost and

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

The design formulae for skew line gear wheel structures oriented to the additive manufacturing technology based on strength analysis [PDF]

open access: yesMechanical Sciences, 2017
In this paper, the design methodology for a skew line gear pair oriented to additive manufacturing technology, with an one-tooth driving line gear and its coupled driven line gear, used for the conventional powered transmission, is researched based on

Configurational Forces on Elastic Line Singularities

open access: yes, 2018
Configurational forces acting on two-dimensional (2D) elastic line singularities are evaluated by path-independent J-, M-, and L-integrals in the framework of plane strain linear elasticity. The elastic line singularities considered in this study are the

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
