Such polymer-solvent secondary bond, however, cannot overcome primary valence cross-link, consequently the cross-linked polymers are less soluble, reducing the softening of the network.
In tomato (Solanum lycopersicum), down-regulation of the ripening-specific SlPG gene only slightly reduced the softening of the fruit [ 22, 23]; and over-expression of SlPG in the ripening-inhibited rin background partially restored PG activity but did not restore fruit softening [ 24].
The larger temperature difference between the environment and the localized temperature rise in the specimens may reduce the strain softening phenomenon.
However, a number of studies have shown that polygalacturonase, pectin methylesterase, β-galactosidase, and β-glucanase suppression are not sufficient to significantly reduce the fruit softening [ 9– 12].
On the other hand, longer pulse durations at a given pulse energy reduce the size of softening zone surrounding the central hardening zone and are thus more favourable for most practical applications.
In addition, the lead oxide present in the yellow, green, and white enamel matrices acts as a flux reducing the enamels' softening temperatures: the higher the amount of lead oxide, the lower the softening temperature of the enamel [7, 29].
Water cooling was found to enhance joint strength, reducing the material softening usually observed in the thermo-mechanically affected zone area, with no detrimental effect on nugget integrity.
These large clusters were harder to dissolve during cycle deformation, thus reduced the cyclic softening effect and enhanced the FCP resistance.
Avoid using fabric softener when washing the sock as fabric softener may reduce the chenille material power.
Alternatively, using a stiff brush to loosen the fibers along the middle section of the backing like a meat tenderizer softens meat will reduce the horizontal pull that causes curling.
