A New Nesting Species For Nebraska, Gary Lingle Dec 1983

A New Nesting Species For Nebraska, Gary Lingle

Nebraska Bird Review

The Chuck-will's widow (Caprimulgus carolinensis) is considered a highly local but regular migrant and presumed summer resident in Nebraska. Although it is known to breed in Kansas and Oklahoma, there were no nest records for Nebraska (Johnsgard, 1980). Egg dates for Kansas range from 21 April to 31 May (Johnsgard, 1979). On 4 June 1983 a Chuck-will's widow's nest with 2 eggs was discovered in a bur oak (Quercus macrocarpa)–red cedar (Juniperus virginiana) woodland at Camp Merrill, Saunders Co. (Sec 29 T17N RSW), approximately 6 miles southeast of Linwood (Janett Waever, pers. comm.) The …

B800: Manual Thinning Of Northeastern Species Using Conventional Cutting Methods, Benjamin F. Hoffman Jr. Dec 1983

B800: Manual Thinning Of Northeastern Species Using Conventional Cutting Methods, Benjamin F. Hoffman Jr.

Bulletins

Harvesting small trees- 4-8 inches in diameter at breast height -has not been common in North America, but as average tree size declines, loggers must cut smaller stems. Many softwood stands in the Northeast contain 2000-4000 stems per acre with mean stand diameters of six inches or less (see Fig. 1). If diameter averages ten inches, there may be 6-7 trees per cord, but if it declines to six inches, loggers may handle four times as many trees for the same volume. Handling this increased number of pieces per unit requires changes in operating techniques.

Manual felling and limbing may …

A Mississippi Kite In Hall County, Nebraska, Gary Lingle, Kari L. Haugh, Lee Morris, Babs Padelford, Loren Padelford Dec 1983

A Mississippi Kite In Hall County, Nebraska, Gary Lingle, Kari L. Haugh, Lee Morris, Babs Padelford, Loren Padelford

Nebraska Bird Review

The Mississippi Kite (lctinia mississippiensis) is considered extremely rare in Nebraska, with only 8 spring records and 2 fall records (Johnsgard, P.A., 1980, A revised list of the birds of Nebraska and adjacent Plains States, Occasional papers of the N.O.U., No.6, Lincoln, Nebraska, 114 pp.). On 10 July 1983, at 12:30 CDT, we sighted an adult Mississippi Kite circling above a flooded native hay meadow on Shoemaker Island, Hall Co. (Sec. 1, T9N R11W). The bird was identified by its frosted head and secondaries, pearly gray back and underside, and black retrices. It is believed this Kite was …

Study Of Bagasse Pulps To Obtain Corrugated Medium, Maria A. Carbonari Dec 1983

Study Of Bagasse Pulps To Obtain Corrugated Medium, Maria A. Carbonari

Paper Engineering Senior Theses

Bagasse was used as raw material to pulp various NSSC, Soda and Kraft liquors and evaluated as corrugating medium. A new pulping procedure with the M & K Digester was developed in order to reach maximum temperature at the shortest practical time.

It was found that a 10% Active Alkali at 5% Sulfidity and an NSSC liquor at pH 10 with 15% SO2 on pulp gave suitable strength properties. The NSSC cook gave a higher yield but a pulp with more shives.

Keywords: Bagasse, Kraft, Soda, neutral sulfite semichemical, corrugating medium


Cleaning And Upgrading Of Post Consumer Corrugated Containers As A Secondary Fiber Source, Daniel L. May Dec 1983

Cleaning And Upgrading Of Post Consumer Corrugated Containers As A Secondary Fiber Source, Daniel L. May

Paper Engineering Senior Theses

Introduction

The use of secondary fiber as a source of raw material in the paper industry is now an important reality ingrained into papermaking. The reasons for using secondary fiber are many and diversified but most point to economy as the primary factor. With wood and virgin pulp becoming more expensive, secondary fiber will undoubtedly maintain its place in the industry and may increase in the future. Total paper production is approaching 88,000,000 tons. Of this total only 23,000,000 is recycled. With nearly 64% of total paper production going to waste either through landfill, incineration or other disposal methods it …


Aspects Of The Nesting Ecology Of Least Terns And Piping Plovers In Central Nebraska, Craig A. Faanes Dec 1983

Aspects Of The Nesting Ecology Of Least Terns And Piping Plovers In Central Nebraska, Craig A. Faanes

Papers in Ornithology

Breeding habitat of the least tern is made up primarily of coastal beaches and inland river sandbars. Populations of the interior (Sterna antillarum athalassos) and east coast (S. a. antillarum) subspecies are now declining (Marshall et al. 1975, Duffy 1977, Jernigan et al. 1978) and the western subspecies (S. a. browni) is endangered (Wilbur 1974). Although coastal populations have received considerable attention (Wolk 1974, Atwood et al. 1977, Blodgett 1978), little research has been conducted on the interior race (Hardy 1957, Downing 1975).

The piping plover inhabits river sandbars and sand beaches and, like …

The Joint Venture Controversy: A Short-Term Solution For A Long-Term Fisheries Policy, Laurie A. Frost Dec 1983

The Joint Venture Controversy: A Short-Term Solution For A Long-Term Fisheries Policy, Laurie A. Frost

Theses and Major Papers

This paper will examine the development of joint ventures under the FCMA, the legislative and regulatory measures designed to control these ventures and the procedures for establishing a joint venture. More recent developments in joint venture policy will be examined, including the controversy over squid joint ventures on the East Coast, to determine what the objectives are and what current policy is regarding join ventures. The debate between harvesters and processors will be put forth as a way of summarizing the costs and benefits of joint ventures to the industry as a whole.

Three methods of determining the validity of the hypothesis were investigated. The mechanisms encompassed with respect to polymer performance were emulsion stability, retention of ASA, and ASA hydrolysis.


Effect Of Hot Supercalendering On Sheets With High Filler Loadings And Polypropylene Fibers Added, Michael R. Whitescarver Dec 1983

Effect Of Hot Supercalendering On Sheets With High Filler Loadings And Polypropylene Fibers Added, Michael R. Whitescarver

Paper Engineering Senior Theses

This study investigates the effects of hot supercalendering on sheets with high filler loadings and polypropylene pulp added. An uncoated sheet that had sheet and optical characteristics similar to a coated number three sheet. was desired. Research was conducted in two stages, handsheet analysis and a machine trial on Western Michigan University's Fourdrinier Pilot Plant. The hot supercalendering of these sheets with 15% Pulpex resulted in a 111% increase in Scott Bond. Unconsolidated Pulpex has no synergestic effects with clay fillers for gloss, brightness, and opacity. Pulpex that has been consolidated does have a synergistic effect with clay for gloss.


The Use Of Old Corrugated Board In The Manufacture Of High Quality White Papers, Rene H. Kapik Dec 1983

The Use Of Old Corrugated Board In The Manufacture Of High Quality White Papers, Rene H. Kapik

Paper Engineering Senior Theses

Clean corrugated board waste was fractionated into its softwood/hardwood fiber components, repulped using a kraft pulping process, and bleached using a CEHD bleaching sequence in an effort to produce high brightness fiber suitable for use in medium to high quality white paper.

The papers produced has almost equivalent mechanical strengths and opacity, but possessed unsatisfactory brightness and cleanliness when compared to commercially manufactured bleached kraft pulps of identical softwood/hardwood contents.

Based on this experimental data, the use of recycled fiber from corrugated board as a fiber substitute in the manufacture of high quality printing and writing papers is not recommended …


Effects Of Ultrasonic Vibration On A Coating Slurry As It Dries On The Sheet, Craig N. Husted Dec 1983

Effects Of Ultrasonic Vibration On A Coating Slurry As It Dries On The Sheet, Craig N. Husted

Paper Engineering Senior Theses

This thesis involves a study of the reaction of coating pigment slurries to ultrasonic vibrations during drying on a sheet of paper. The coating was done with a Meyer Rod and immediately transferred to the surface of a loudspeaker apparatus until dry. Several different coating formulations were used and evaluated with and without ultrasonic agitation. These coatings include combinations of #2 clay, delaminated clay, titanium dioxide, calcium carbonate, and polystyrene plastic pigment. Frequencies of 25,000 Hz and 42,000 Hz were used as well as the control group which was not treated. The amplitude was the highest attainable with the frequency …
