Book excerpt: Excerpt from A Preliminary Study of Tearing Instruments and Tearing Test Methods for Paper Testing 1. Statement Of Problem For some time it has been a recognized fact in the paper industry that there is a need for an instrument that will give numerically the tearing strength of paper. Considerable work has been done along this line at different laboratories. The result has been that two types of tearing instruments have been invented and are used to some extent. One of these types is a recording instrument, giving a curve showing the maximum and minimum tearing strength of paper and the results of five initial tears. The other type gives merely the maximum tearing strength by weighing or measuring the load applied to the paper to tear it. Both types have their good and their bad points, which will be brought to light in the following study. II. Discussion Of Test Methods 1. Practical Tests With Different Size Test Samples Before taking up a study of the instruments themselves it must be remembered that the tearing strength of paper depends a great deal on the size of the test sample. For instance, a series of bag papers that had previously been tested for weight (in pounds) of the standard size ream 25 X 40 - 500 and for bursting strength were torn on the tensile-strength instrument described in Bureaus Circular No. 107, pages 15-17, and on the two types of tearing instruments mentioned above. For convenience, let the recording instrument be called type I and the nonrecording instrument type II. The test samples were cut 1 by 8 inches for the tensile-strength machine, 23/4 by 1 1/8 inches for type I instrument, and 4 by 10 inches for type II instrument. All samples were torn the machine direction, beginning at a point just halfway across the width of the test sample, and an average of 10 tests was taken for each result. The results in Table 1 were obtained. It might be well to mention here that all tests in this study were conducted in a constant-temperature and humidity room, where all test samples before they were used were conditioned for two hours at a temperature of 70 F and a relative humidity of 65 percent. From these data it is to be noted that the larger the test samples are in size the higher are the values of tearing strength.

Available in PDF, EPUB and Kindle. Book excerpt: . Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal. A stone when struck resists. If its resistance is greater than the force of the blow struck, it remains outwardly unchanged. Otherwise, it is shattered into smaller bits. Never does the stone attempt to react in such a way that it may maintain itself against the blow, much less so as to render the blow a contributing factor to its own continued action. While the living thing may easily be crushed by superior force, it none the less tries to turn the energies which act upon it into means of its own further existence. If it cannot do so, it does not just split into smaller pieces (at least in the higher forms of life), but loses its identity as a living thing. As long as it endures, it struggles to use surrounding energies in its own behalf. It uses light, air, moisture, and the material of soil. To say that it uses them is to say that it turns them into means of its own conservation. As long as it is growing, the energy it expends in thus turning the environment to account is more than compensated for by the return it gets: it grows. Understanding the word "control" in this sense, it may be said that a living being is one that subjugates and controls for its own continued activity the energies that would otherwise use it up. Life is a self-renewing process through action upon the environment.

Your focus on the essence of learning combined with concrete examples of the daily challenges of teaching and clear tactical strategies for faculty to consider is a welcome work. I will recommend this book to all my colleagues." —Catherine M. Casserly, senior partner, The Carnegie Foundation for the Advancement of Teaching "As you read about each of the seven basic learning principles in this book, you will find advice that is grounded in learning theory, based on research evidence, relevant to college teaching, and easy to understand. The authors have extensive knowledge and experience in applying the science of learning to college teaching, and they graciously share it with you in this organized and readable book." —From the Foreword by Richard E.
