The influence of the manner and degree of compression on some physical and mechanical properties of molded wood-resin blends was studied. Yellow birch (Betula alleghaniensis) and Douglasfir (Pseudotsuga menziesii var. menziesii) particles, processed from .015-inch by 1-inch flakes, were used. The properties evaluated were modulus of rupture, modulus of elasticity, dimensional stability, water absorption, and flow. Flow was considered to be the ability of a blend to move in directions at right angles to an applied force. A method for evaluating such flow is described. Toward the upper limit of the compressive range, the degree of compression is more important than the manner (rate) of compression. Along with resin content, the degree of compression controls the formation of glue bonds which, in turn, control the properties of the molded product. The primary importance of species and particle size is in the influence of these variables on effective mat compression. (Author).
In the last half-century, the number of Catholic priests has plummeted by 40% while the number of Catholics has skyrocketed, up 65%. The specter of a faith defined by full pews and empty altars hangs heavy over the church. The root cause of this priest shortage is the church's insistence on mandatory celibacy. Given the potential recruitment advantages of abandoning the celibacy requirement, why, Richard A. Schoenherr asks, is the conservative Catholic coalition--headed by the pope--so adamantly opposed to a married clergy? The answer, he argues, is that accepting married priests would be but the first step toward ordaining women and thus forever altering the demographics of a resolutely male religious order. Yet Schoenherr believes that such change is not only necessary but unavoidable if the church is to thrive. The church's current stop-gap approach of enlisting laypeople to perform all but the central element of the mass only further serves to undermine the power of the celibate priesthood. Perhaps most importantly, doctrinal changes, a growing pluralism in the church, and the feminist movement among nuns and laywomen are exerting a growing influence on Catholicism. Concluding that the collapse of celibate exclusivity is all but inevitable, Goodbye Father presents an urgent and compelling portrait of the future of organized Catholicism.
