Tb65: The Commercial Use Of Puckerbrush Pulp, Andrew J. Chase, Fay Hyland, Harold E. Young

Technical Bulletins

This study investigates the potential of several local puckerbrush or weed trees and shrubs as sources of fiber for papermaking. Four different pulping processes were used (sulfate, magnesium bisulfite, neutral sulfite semichemical, and cold caustic) with six puckerbrush species (alder, gray birch, red maple, pin cherry, aspen, and willow). Mixtures of puckerbrush species, and commercial chip-puckerbrush species mixtures were pulped by the sulfate process with the objective of producing a pulp that would be suitable for fine-grade papers. The results produced a good grade of bleachable pulp with adequate physical characteristics for most fine paper grades. The other three pulping …

Effects Produced By Varying Types Of Drying On Starch Coated Paper Properties And Binder Migration, Mark J. Schaefer

Paper Engineering Senior Theses

The major concern of this report is binder migration and the factors which play a major role contributing to its presence. The major factors studied were coatings using varied drying methods, adhesive levels, % solids and types of starches.

Results obtained show that to obtain minimal migration coatings should be dried evenly throughout using infrared sources of heat.

Coating with different adhesive levels will vary optical and strength properties. Binder migration is more evident when using lower adhesive levels.

Coating at different % solids did not have any real significant effect in this study due to a very short span …

The Effects Of Speed Of Web On The Coat Weight Variation In Blade Coating, Pak Kee Lee

Paper Engineering Senior Theses

Numerous works have been done on the investigation of coat weight variations by various researchers. The mechanism of the variation, in a given base stock, is explained by the two models - the hydrodynamic pressure which is a strong function of the web speed, and the visco-elastic or normal force. For a given coating color, viscosity is a function of the web speed which causes the shearing action to take place. Increasing the speed will cause an increase in hydrodynamic pressure as well as visco-elasticity, which tend to lift up the blade and thus a higher coat weight will be …

Post-Settlement Land Uses And Their Effects On The Cedarburg Bog, Nevin J. Farley, Peter J. Salamun

Field Station Bulletins

During a study of the plant species of a lowland hardwood stand at the western edge of the Cedarburg Bog (Farley, 1973), it was noted that significant environmental changes had occurred here and throughout the bog which resulted in the present-day vegatation patterns. Many of these changes can be attributed to the various post-settlement land-use practices which were employed in the Town of Saukville (TllN, R21E), Ozaukee County, Wisconsin, where this bog is located. To document this information a literature survey was made of the various studies which ha ve been carried out in this area (Cutler, 1936; Grittinger, 1969; …

Prairie Establishment At The Field Station, Philip B. Whitford

Field Station Bulletins

Early in the development of the Cedar-Sauk Field Station it was decided to attempt establishing a sample of prairie vegetation as an experimental and demonstration project. Although none of the field station land had prairie soil and the nearest site of original native prairie was probably at least twenty miles distant, we felt that this area was close enough to the original prairies climatically so that most of the prairie species native to southeastern Wisconsin should be able to survive. If even moderately successful, it would provide an additional habitat for studies of animal life at the station, a demonstration …

Effects Of Controlled Overdrying On Some Physical Characteristics Of Paper Related To Printing Press Performance, Kenneth C. Pearson

Paper Engineering Senior Theses

The purpose of this study was to determine the effects of certain drying variables on some physical strength properties when these variables were controlled to bring about overdrying conditions. The variables under study were length of time and degree of temperature in relation to amount of drying produced. The results were then related to dimensional stability, tensile, stretch and mullen in an attempt to establish a relationship of overdrying to these physical characteristics.

The dimensional stability was run on the Neenah Multiple Specimen Expansimeter with tensile, stretch and mullen all run according to respective Tappi Standards.

A Linear Programming Decision Model For Elk And Deer Management On The Logan Peak Winter Range Area, Ronald P. Grove

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

One consequence of our surging human population is the corresponding increased level of resource consumption. This occurrence renders it imperative that resource managers intensify their management of the world's natural resources. Failure to improve management techniques involving the use of these resources will result in premature depletion of non-renewable commodities and severe checks on the vigor of renewable resources.

Management is faced with the difficult task of searching for astute means of allocating natural resources. Because of the tremendous size and complexity of the natural world, the problem can be extremely complicated.

Mathematical techniques have proved useful in providing natural …

A Description Of Anglers And Angling Use In Two Areas Of The Uinta Mountains, John F. Hoagland

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The High Uinta Primitive Area, Utah's most popular high mountain recreation area, has a reputation as an excellent trout and grayling fishery. Proposed for inclusion in the National Wilderness Preservation System, the area faces several management dilemmas. The primary problem being that managers must protect the resource from the effects of heavy recreational use without destroying the primitive and aesthetic dimensions of wilderness environment. It appears that much impact on the more accessible lakes is due to fishing use. The objectives of the study were: (1) to determine the proportions of angling to non-angling groups; (2) to describe certain characteristics …

The Local Interest As A Consideration In The Planning Of Highway Construction In The Canyonlands Region Of Southeastern Utah, Robert L. Barry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An examination was conducted of the potential of proposed highway construction for serving the needs and interests of the population of the Canyonlands Region of southeastern Utah. The history of the highway development issue in the region was first examined with special attention given to the local position on the issue as expressed by local government spokesmen. Next, the total system of development proposals for the region was divided into four sections using criteria of area served and degree of controversy. A map analysis was conducted to determine how these four separate proposals would serve transportation needs of the region. …

Criteria For Recreation Site Selection On Flood Control Reservoirs-Case Studies, Kenneth B. Mclaughlin

Electronic Theses and Dissertations

Stephen F. Austin State University was awarded a contract in August 1971 to select the 1,200 acres best suited for recreation area development on three proposed flood control reservoirs. At that time, there was no central publication which could be used as a guide for such a project. This thesis was written to help correct this situation. The nine factors that were used in initial site selection are soils, topography, access, wind, vegetation, land ownership, distribution of the sites, bridges and open-water and cove locations. Once the sites were selected, they were evaluated and assigned priorities for development according to …

Rate Of Growth Of Tamarack (Larix Tarcina) In Cedarburg Bog, Cynthia Meyer

Field Station Bulletins

This study was undertaken to determine the influence of bog conditions on growth rate of tamarack (Larix larcina). The Cedarburg Bog in Ozaukee County, Wisconsin presents a unique opportunity for such study since it includes the southernmost string bog in the United States (Grittinger, 1970). My results demonstrate very slow growth of tamarack in Cedarburg Bog both in diameter and height. Differences in growth rates depend on the particular area of the bog, aeration, and mineral availability. As indicated by other studies, much more work is needed to determine how various factors affect growth of trees as well as other …

Black-Capped Chickadee Behavior-Fledging To Dispersal, Mary Van Male

Field Station Bulletins

Most studies of the family life of young birds after they leave the nest have been descriptive and anecdotal with little quantitative behavioral data, despite the many interesting problems involved in interactions of the members of a family. The objectives of this study were to determine: 1) the behavior of parents and young Black-capped Chickadees (Parus atricapillus) at the time of leaving the nest, 2) how the parents and young behave towards each other during the period when the young are dependent on their parents, 3) the factors responsible for the final disruption of the family. Since aggression was anticipated …

Submergent Macrophytes In Theresa Marsh, James Mcnelly, Jeffrey Klopatek

Field Station Bulletins

Marshes form the interface between upland and aquatic systems and, like most transitional zones, provide habitat diversity which may support a great variety of life. Marshes may act as valves or sinks to regulate the flow of mineral nutrients from terrestrial systems (especially from agricultural or urban systems) to aquatic zones. Freshwater marshes and wetlands are ranked with coastal estuaries as highly productive areas and play an important role in converting the sun's energy to organic matter.

Recovery Of Fillers From Paper Mill High Ash Sludge By Froth Flotation, Prakasha Chandra Misra

Paper Engineering Senior Theses

The purpose of this project was to recover filler materials (most of which are clay) from the paper mill primary clarifier high and sludge utilizing froth flotation.

Initial attempts to determine the dosage of a water soluble cationic surfactant EHDA-Br did not prove successful. It was discarded, an a partially water soluble cationic surfactant was taken up next. With a dosage of 0.75% (based on suspended solids) and an air flow rate of 1.5 - 1.75 1/min. it was possible to increase the ash content over 68% (minimum 66.5%, maximum 69.5%) in the foam fraction after single stage flotation, compared …
