A Statistical Analysis Of Strength Characteristics Of Handsheets, Edward J. Horvath

Paper Engineering Senior Theses

A literature survey was made in order to provide an outline of fundamental statistical definitions, formulas and methods which are used by the paper technician. These methods, if properly applied, would furnish valuable information as to the accuracy of test values, significance of differences and merits of various operations.

A demonstration is made of the application of statistical methods to test data obtained from samples of unbleached kraft pulp in the form of wet laps, air-dry pulp and soaked pulp. The analysis was devoted to the study of strength variations, uniformity and duplicability of handsheets produced from the three samples.

Microscopy Of Newly Developed Paper Making Fibers, Richard E. Hathaway

Paper Engineering Senior Theses

The more important of the newly developed fiberous paper making materials are bleached groundwood, West coast kraft, hardwood kraft, semichemical pulp and cotton linters. The weight factors of these fiberous materials have been determined by several different investigators, but their identification in a paper furnish is very difficult. The weight factors of cotton linters varies with the freeness of the sample, which can be determined by dying the fibers with a mixture of a direct orange and a direct blue bye. Differentiation can be made between bleached and unbleached groundwood with the Loften-Merritt stain. Staining methods cannot be used to …

The Influence Of Electrolytes On Certain Characteristics Of Pulp, Wayne Eugene Kendrick

Paper Engineering Senior Theses

This thesis is an endeavor to bring out the reasons for strength variations due to the presence of electrolytes in the process water, occurring either naturally or in the form of additives. The subject is subdivided into effects caused by cations and effects caused by anions plus special cases.

Material was obtained from the science library of Western Michigan College of Education, the Kalamazoo Public Library and microfilmed articles from the New York Public Library.

Agricultural Productive Capacity 1955 South Dakota, South Dakota Agricultural Experiment Station

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

Our agricultural resources have a strategic role to play in the present mobilization effort. Even a partial military mobilization calls for a large increase in food. Our population has increased by 20 million people since 1940. Our civilian per capita food consumption is up 13 percent, our agricultural exports are up 50 percent above the 1935-39 average and food surpluses have largely disappeared. Estimates of our agricultural productive capacity are needed to determine whether such capacity is great enough to meet future needs and to help the nation make wise decisions concerning such vital questions as these: 1. How much …

Use Your Time Efficiently, Isabel Mcgibney

SDSU Extension Circulars

There are only 24 hours a day. No matter how hard we try we cannot make more. Time cannot be found, spent or saved it can only be used. Time may be used wisely to gain many desired satisfactions, or it may be used unwisely with few pleasant results. If we want to use time wisely and save effort, we must be willing to admit there is room for improvement. We must also be willing to change from the old "in the rut" way to a new way of doing our job. Each of us sets our own pattern of …

Reduced Ascorbic Acid Content Of Potatoes Grown With And Without Straw Mulching And Irrigation In Eastern Nebraska, H. O. Werner, Ruth M. Leverton, Mary R. Gram

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Potatoes harvested from home gardens and in commercial early-producing fields in the Midwest are an important low-cost source of ascorbic acid from late June into September. The major portion of the early commercial crop in Nebraska (harvested mostly in August) is produced with irrigation. Straw or litter mulching is a well established practice in the nonirrigated garden and farm potato patches. The value of these cultural methods for increasing yield is well known, but prior to this study little was known about their influence on the ascorbic acid content of the tubers, or about the persistence of any such influence …

Geographic Variation In Toads Of The Debilis Group Of Bufo, Ottys Sanders, Hobart M. Smith

Field and Laboratory

In 1938, Taylor (1938,513) for the first time pointed out the existence of two distinct forms of toads in the assemblage previously referred to Bufo debilis. These he designated as the species Bufo insidior Girard and Bufo debilis Girard. Since then much confusion has reigned, especially with respect to the range and status of the southeasterly form regarded as B. debilis.

Range And Habitat Of The Clam Polymesoda-Caroliniana (Bosc) In Virginia (Family Cycladidae), Jay D. Andrews, Catherine Cook

VIMS Articles

The clam Polymesoda caroliniana (Bosc), which ranges north and eastward in brackish waters from Lavaca Bay, Texas,2 has not pre- viously been reported north of the Neuse River, N. C. (Van der Schalie 1933). On 7 April 1947, Richard Hoffman found several shells on the beach above Swann Point on the James River, a tributary of Chesapeake Bay (Fig. 1). On 20 April 1947, J. P. E. Morrison (personal communication) and Hoffman found living specimens in the mud and detritus around the knees of cypress trees one-half mile above Swann Point. These records are included in this paper through the …
