Measurement Of Residual Lung Capacities And Ventilatory Efficiency By The Nitrogen Clearance Method, Elizabeth Roorbach

Biology ETDs

Essential to an understanding of the behavior of the lung is a knowledge of its total gas capacity and those fractions of it which are utilized in the process of normal breathing. Only when these volumes are known, it is possible to make an appraisal of the efficiency of the pulmonary ventilation in maintaining physiologically adequate levels of oxygen and carbon dioxide in the alveolar spaces with a minimum of ventilatory effort.

A Study Of An Unusually Heat Resistant Variant Of Bacilius Circulans, Roberta D. Demaret

Biology ETDs

The problem herein described was initiated while following the growth rate of a culture over a ten-hour period. A flask of polypeptone agar had been held in a 47-degree Celsius water bath to maintain it melted so that the plates could be poured periodically. The plates poured during the last two or three hours were found to be heavily contaminated with a Gram-positive, aerobic, sporeforming bacillus. Aseptic technique had been used in pouring the plates; however, external contamination was possible over the long pouring interval, so the test was repeated incubating a flask of the sterilized medium in the water …

The following key summarises the principal differences between E. longif olium and E. vespinum.

The Influence Of Varying Hydrogen Ion And Alumina Concentrations On The Strength Characteristics Of Handsheets Made In The Presence Of Locust Bean Gum, Ronald L. Hamilton

Paper Engineering Senior Theses

Mannogalactans and particularly locust bean gum are used for a wide variety of applications. They serve as thickening agents and emulsifiers for foodstuffs, in sizing as well as finishing yarns and in creaming rubber latex. The papermaking industry is the largest user of mannogalactans. Here they are used in kraft grades, sulphite, book papers, coating raw stock, offset and printing grades, bonds, ledgers, and other fine papers and also in newsprint and other groundwood sheets.

Locust bean gum and methylcellulose are effective as deflocculating agents and are said to surpass the performance of deacetylated karaya gum. Both hydration film and …

South Dakota's Farm Accident Toll, Agricultural Extension Service, South Dakota State College

SDSU Extension Circulars

Facts regarding farm accidents are scarce. A suggestion was made by the state safety director, Carroll Stinson, to the agricultural engineering department that a newspaper clipping survey be made to determine in what areas an educational program might best be developed to cut down on the occupational hazards of modern agriculture. One hundred fourteen of the 185 weekly and eight of the 12 daily papers cooperated in making this survey. Agricultural engineering students clipped out accident reports each week from these papers from November 1, 1952 through October 31, 1953. This survey was restricted to on-the-farm accidents except those accidents …

The Influence Of Pith Cells On The Papermaking Characteristics Of Pulp From Bagasse, Miguel A. Cabrera

Paper Engineering Senior Theses

Literature Survey

Introduction

The fact that the need for paper products is increasing in an unparallel manner with the wood resources available at the United States market, has open the field for research studies in the development of new raw materials.

Bagasse has been a waste product submitted to intense laboratory investigation due to the fact that is a world available and relatively cheap fiber. Its use as a papermaking material has been investigated over a 100 years. Its development has been attacked by the different and contradictory opinions obtained from pilot plant runs and lack of knowledge techniques in …

Fiber Length As A Variable Influencing Wet Strength, Charles Elliott

Paper Engineering Senior Theses

It was desired to discover the influence of fiber length on wet strength obtained by the addition of a resin. The wet strength tests chosen were the tear and tensile, the retention of the resin was also measured. The resin used was melamine formaldehyde acid colliod.

The wet tensile showed no significant drop with decreasing fiber length until the fibers were cut very short. The wet tear was shown to be very sensitive to any change in fiber length. The retention of the resin was relatively unaffected by the fiber length.

Feeding Poultry For Profit, Glen Hart, C. W. Carlson

SDSU Extension Circulars

Feeding poultry for profit involves essentially the use of top quality stock, proper management and care, proper facilities, and last, but certainly not least important, a good feed. The feed accounts for well over 50 per cent of the cost of poultry, meat and egg production, hence its importance cannot be considered lightly. A good feed supplies all of the essential nutrients in the required amounts for each type of production.

Agricultural Education Through News, Burton Seeker

SDSU Extension Circulars

If a visitor came into your office and offered to influence a thousand people in your behalf, with no cost or obligation to you, would you take him up on it? Your job is education. Your problem is reaching the great number of people in your county with the wealth of information you have at hand. Of course you would jump at the chance. That man is your local newspaperman. Extension education is primarily a proposition of personal contacts through schools, meetings, field tours and farm visits. Yet not everyone is enrolled in your crop improvement association or home demonstration …

The Performance Of Sodium Hypochlorite And Sodium Hypobromite As Bleaching Agents At Varying Levels Of Hydrogen Ion Concentration, Ted Jewson

Paper Engineering Senior Theses

Limited information was found in literature survey on the bleaching of wood pulp by means of hypobromites. Experimentation showed that the addition of sodium bromide to sodium hypochlorite results in accelerated bleaching. The optimum pH range for bleaching was found to be higher in presence of hypbromites than in straight hypochlorite bleaching. The maximum brightness values obtained in bleaching with either straight sodium hypobromite or with mixtures of hypochlorite and hypobromites were lower than those obtained with sodium hypochlorite.
