Immune Defense Mechanisms of the Dental Pulp

Critical Reviews in Oral Biology & Medicine, 1998
Defense reactions of the dentin/pulp complex involve a variety of biological systems, in which the immune system plays a pivotal role. The knowledge of the organization and function of pulpal immunocompetent cells has been sparse, but in recent years a significant body of information of immune mechanisms in general has provided a footing for ...

Swelling of mechanical pulp fines

Cellulose, 1999
The objective of the study was to determine the swelling of different types of mechanical pulp fines. The physical and chemical characteristics of the fines were also examined. It was found that the degree of swelling correlates with the proportion of fibrillar material, that is fibrillar content of the fines.

The Mechanism of Hornification of Wood Pulps

Trans. of the Xth Fund. Res. Symp. Oxford, 1993, 1993
Hornification is the loss of swelling of the fibre wall resulting from a drying-and-rewetting cycle: it is associated with a stiffening of the fibres which reduces their ability to form inter-fibre bonds. In this paper,factors affecting the extent of hornification are examined using the solute exclusion technique to measure swelling.

Use of Enzymes in Mechanical Pulping

2018
Mechanical pulping process is an energy-intensive process. Enzyme treatment of wood and pulp is an attractive alternative to reduce energy demand in the refining process and to introduce novel functional properties of fibers. This chapter discusses the use of enzymes in mechanical pulping process.

Experiments on Specific Energy and Pulping Quality of Extrusion Mechanical Pulping

Key Engineering Materials, 2011
In order to select rational screw parameters for improving the pulping quality, efficiency and reducing specific energy, the paper studied the effects of the rotational speed of screw, lead number of reverse thread and slot width of reverse flight of the twin screw pulping extruder (TSPE) on specific energy, flux and pulping quality (reject rate, fiber
