Cracking at the fold is a serious issue for many grades of coated paper and coated board. Some recent work has suggested methods to minimize this problem by using two or more coating layers of different properties. A discrete element method (DEM) has been used to model deformation events for single layer coating systems such as in-plain and out-of-plain tension, three-point bending, and a novel moving force picking simulation, but nothing has been reported related to multiple coating layers. In this paper, a DEM model has been expanded to predict the three-point bending response of a two-layer system. The main factors evaluated include the use of different binder systems in each layer and the ratio of the bottom and top layer weights. As in the past, the properties of the binder and the binder concentration are input parameters. The model can predict crack formation that is a function of these two sets of factors. In addition, the model can predict the flexural modulus, the maximum flexural stress, and the strain-at-failure. The predictions are qualitatively compared with experimental results reported in the literature.

Ruth, a tale of human kindness and just dealing far beyond the norm, contains elements that for centuries have been the subject of debate. With a sprightly translation and a commentary rich in informed speculation, Professor Campbell considers the questions of layman and scholar alike. Finding no overt mighty acts, the layman asks, “Why was Ruth included in the Bible at all? Where is God?” Professor Campbell shows that God is not only present throughout but is indeed the moving force behind all the developments of the story. Naomi, Ruth, and Boaz each act as God to each other, by taking extraordinary responsibility and performing extraordinary acts of kindness. And it is God who is responsible for the series of coincidences on which the plot hinges. The scholar’s questions deal with such matters as purpose, date, and genre. Professor Campbell’s research into ancient customs and linguistics suggests to him that Ruth is a historical novelette, entertaining and instructive, composed not long after the reign of King David, during the time of Solomon or within the subsequent century. Professor Campbell demonstrates the storyteller’s skill with sensitive analysis of form, pacing, and wordplay. By delving into word origins and nuances he shows how convincingly the characters are developed. One instance: Naomi and Boaz use obsolescent language, emphasizing the generation gap between them and Ruth. In addition, the illustrations help the reader understand unfamiliar elements of the story—the setting, the agricultural seasons and harvesting, the clothing of the times, the city gate where elders and interested villagers gather to make sure that all is done in a just and godly way.
