Understory Changes Following A Prescribed Burn In A Central Illinois Oak-Hickory Forest, Charity Rae Hilchen

Masters Theses

The understory of Baber Woods, Edgar County, Illinois, was surveyed from April to September, 1988, following a low intensity fall burn in November, 1987. From plots sampled in the spring, summer and fall, differences in the composition of the herbaceous and woody components between the burn and control areas were determined. The herbaceous component of the burn area was found to compose a significantly higher percentage (X2 . 05 , 2 =12.49) of the importance values (IV) over all the sampling periods. Acer saccharum was found in significantly lower frequency (X2 . 05 , 2 =24.8) in the …

Effects Of The Addition Of Binder On The Packing Characteristics Of Pigment Particles, Rajesh K. Garg

Masters Theses

This study describes in a quantitative manner the relationships between coating structure and optical properties. Scattering coefficient, gloss and pore volume were measured after applying different blends of polystyrene spheres using various amounts of binder to transparent Mylar film. The coatings were prepared using four proportions of two sizes of polystyrene spheres and varying amount of two binders, starch and latex respectively. Optical properties of coatings were related to changes in coating structure. A scanning electron microscope was used to observe the structure and to facilitate void size measurement. The void size distribution correlated very well with the scattering and …

A Study Of Alkaline Sodium Sulfite Pretreatment Of Spruce During Thermomechanical Pulping, Nagaraju Dendukuri Jun 1988

A Study Of Alkaline Sodium Sulfite Pretreatment Of Spruce During Thermomechanical Pulping, Nagaraju Dendukuri

Masters Theses

A review of literature relating sodium sulfite pretreatment during thermomechanical pulping to pulp physical properties revealed many contradictions. Thermomechanical pulping variables were studied for their effect on pulp physical properties. An improvement in pulp physical properties was observed above 1% sodium sulfite treatment. Regression analysis and analysis of variance showed that there was a significant effect of sodium sulfite on the reduction of shive content, pulp brightness, and tear index. Fiber length, tensile, burst, and density were not found to be significantly affected by the amount of sodium sulfite. Sodium sulfite treatment during thermomechanical pulping showed a negative relationship with …

A Woody Understory Survey Of Baber Woods, Edgar County, Illinois, Jacqueline M. Spencer

Masters Theses

The understory of Baber Woods, located in Edgar County, Illinois, was surveyed to see if sugar maple had increased enough in importance to consider implementing some type of forest management technique. Five 100 meter transects were randomly located in closed canopy areas throughout the woods. Specimens were removed from continuous 1 meter quadrats located along each line. Specimens were also removed from twenty 25 meter transects located in the open canopy areas. Species, age, height, diameter, and quadrat number were recorded for each specimen. The data was analyzed for age-height and age-diameter relationships, plus individuals per hectare, density, frequency, relative …


An Understory Survey Of Baber Woods, Edgar County, Illinois, Amy Jo Burns Jan 1986

An Understory Survey Of Baber Woods, Edgar County, Illinois, Amy Jo Burns

Masters Theses

Several vegetation studies have been undertaken in Baber Woods, Edgar County, Illinois, in the past 20 years. After looking at the data of these studies it was decided that an additional study was needed to determine if the increasing importance value (IV) of Acer saccharum was indeed important. It appears that this species is starting to take over the native oak-hickory woods as well as decreasing the diversity of the herbaceous understory (Ebinger, 1986). The present study was undertaken to determine of Acer saccharum has increased enough to justify implementation of some type of forest management.

Environmental parameters at the …


Microencapsulation As An Alternative To Emulsification For Preparing As A For Use In Papermaking, William J. Corriveau Dec 1985

Microencapsulation As An Alternative To Emulsification For Preparing As A For Use In Papermaking, William J. Corriveau

Masters Theses

The sizing chemical ASA is emulsified to make i t compatible with the papermaking process. Unfortunately, emulsified ASA is chemically reactive with water at the elevated temperatures found in papermaking systems. As an alternative, encapsulated ASA was made and investigated for its stability towards water at elevated temperatures.

A handsheet procedure was developed to analyze emulsified and encapsulated ASA. It was concluded that the procedure gave statistically reproducible results. Investigations with the procedure revealed important variables concerning the laboratory and m ill application of ASA. Evidence indicated that retention of ASA was critical to sizing development.

Encapsulated ASA made for …

Sugar maple had the highest Importance Value (IV) of all woody species present, having the highest density in both the 4-6 and 7-12 inch diameter classes, as …


Factors Influencing Reforestation Of Surface Mined Lands In Southern Illinois, Jill R. Medland Jan 1983

Factors Influencing Reforestation Of Surface Mined Lands In Southern Illinois, Jill R. Medland

Masters Theses

Studies of surface coal mined lands have focused primarily on older lands mined prior to the enactment of reclamation legislation. Current laws will require extensive grading, soil replacement and revegetation. In order to more effectively reforest these lands, I have evaluated sites planted to woody species during the past decade.

The vegetational characteristics, as well as both avaian and small mammal populations of several reclaimed surface mined areas, differing in age and reclamation procedures, were compared. Success of planted trees ranged from 50 to 91% and survival varied with the species planted. There was no relationship between tree survival and …

A Survey Of Management Opinions Of Noise In The Pulp And Paper Industry, Carola Trittin Jun 1958

A Survey Of Management Opinions Of Noise In The Pulp And Paper Industry, Carola Trittin

Masters Theses

Introduction

The pulp and paper industry is the fifth largest in the United States, dollar-wise, and is also the third fastest growing industry in the United States (1). There are between 375,000 and 400,000 people employed directly in the pulp and paper mills in the United States and Canada. A nation-wide survey on the importance of noise in this industry is needed to help clarify the effects, if any, that noise has upon its employees.

By definition, noise is non-harmonious sound. When the subject of noise is mentioned, many suggestions are given on places where such a study should be …
