Competitive Orientations And Motives Of Adult Sport And Exercise Participants, Diane L. Gill, Lavon Williams, Deborah A. Dowd, Christina M. Beaudoin, Jeffrey J. Martin

Kinesiology, Health and Sport Studies

Participants in four different adult sport and exercise programs (running club, exercise classes, cardiac rehabilitation program, senior games) completed measures of competitive orientation and participation motivation. Our samples were older and more diverse than samples of previous research, and their competitive orientations and motives were similarly diverse. Multivariate analyses revealed gender and sample differences. Males were higher than females on competitiveness and win orientation, and runners were less win-oriented than other groups, but overall, all groups were similar to previous college-age samples in competitive orientation. Groups varied on specific motives, with females rating fitness, flexibility, affiliation, and appearance higher than …

The Theme Of "Relevance" In Third World Human Sciences, Syed Farid Alatas

farid alatas

The fact that the humanities and social sciences in developing societies generally originated in the West has raised the issue of the relevance of these arts and sciences to the needs and problems of Third World societies. This questioning of relevance has led, in turn, to the call for the indigenisation of knowledge in developing societies. While there has been a great deal of discussion on indigenisation, there has been little practice of indigenised humanities and social science. As a result, there are few examples of what indigenous knowledge constitutes from theoretical, methodological and empirical points of view. This paper …

Repulping Bottle Carriers, Mahsa Khosravani

Paper Engineering Senior Theses

Wet strength resins are used to enhance the strength of the paper in the presence of water and high humidity. Paper makers have a difficult time breaking down the wet strength resins which are used to aid in this process. The ideal situation would be to have high wet strength and still be able to brake it down easily. Unfortunately wet strength paper keeps its integrity because of the chemistry involved in its preparation. The chemistry that protects the structure of the high wet strength paper will also defend it in the pulper. The problem that causes the main concern …

Repulping Bottle Carriers, Jennifer A. Giver

Paper Engineering Senior Theses

The primary object of this thesis project was to repulp post consumer bottle carriers with the addition of chemical reagents and mechanical shear. Recycling bottle carriers is difficult to achieve due to the chemical additives that are added to the pulp. Chemical additives introduced to the virgin pulp are wet strength resins.

Post consumer bottle carriers used in this experiment contained Kymene 557, which is a wet strength product produced by Hercules incorporated and is difficult to repulp due to the cross-linking employed by this chemical additive. This experiment utilized both oxidizing and reducing chemical reagents such as hypochlorite and …

Electrokinetic Dewatering Of Softwood Furnishes, Aaron R. Redman

Paper Engineering Senior Theses

Enormous quantities of water are required in the preparation and formation of paper products. One of the most costly operations in paper manufacture is removal of excess water from the sheet and disposal of by-products from paper production. Currently, high steam energy is necessary in the drying process of paper manufacture. Disposal of a paper by-product, sludge, is also a rising concern due to environmental risks, shrinking landfill space, and rising disposal costs. Both production costs and disposal costs could be reduced with a more effective and efficient process to enhance water removal in paper production and sludge disposal.

A Study Of The Effect Of Recycling On The Bonding Ability And Characteristics Of Fines, Lon E. Pschigoda Ii

Paper Engineering Senior Theses

The recycled paper industry has seemingly grown faster than the technology to go along with it. It has become accepted that along with paper recycles comes a certain amount of strength loss, limiting the uses of secondary fiber. If the recycling industry is continued to grow an effective counter to this strength loss needs to be found. In order to counteract this strength loss the mechanism must first be better understood. The three mechanisms that will be focused on for this paper will be 1) The loss of fiber length, 2) Hornification, and 3) The decrease in surface bonding activity. …

Treating Recycled Papers With Naoh For Strength Improvement, Satoshi Suga

Paper Engineering Senior Theses

Loss of strength is one of the worst aspects of recycled papers. Even though several factors are responsible for this phenomenon, loss of fiber swelling and inter fiber bonding are believed to be the main contributors. Therefore, prevention of loss in swelling and inter fiber bonding of recycled pup should result in the minimum strength loss of recycled papers.

Chemicals with hydroxyl group such as NaOH are known to provide superior swelling power to.pulp, and their swelling power might be utilized to minimize the strength loss of recycled paper.

In this study, batches of bleached kraft paper were repulped at …

The Bradyrhizobium Japonicum Fega Gene Encodes An Iron-Regulated Outer Membrane Protein With Similarity To Hydroxamate-Type Siderophore Receptors., Kristin Levier, Mary Lou Guerinot

Dartmouth Scholarship

Iron is important in the symbiosis between soybean and its nitrogen-fixing endosymbiont Bradyrhizobium japonicum, yet little is known about rhizobial iron acquisition strategies. Analysis of outer membrane proteins (OMPs) from B. japonicum 61A152 identified three iron-regulated OMPs in the size range of several known receptors for Fe(III)-scavenging siderophores. One of the iron-regulated proteins, FegA, was purified and microsequenced, and a reverse genetics approach was used to clone a fegA-containing DNA fragment. Sequencing of this fragment revealed a single open reading frame of 750 amino acids. A putative N-terminal signal sequence of 14 amino acids which would result in a mature …

The Effects Of Recycling On A Never-Dried Softwood Kraft Pulp Beaten To Different Initial Freeness Levels, Heath A. Smith

Paper Engineering Senior Theses

The objective of this study is to compare two different pulps, a softwood kraft pulp with a groundwood pulp, to see if there is any difference in the behavior of their sheet properties as they are recycled. Neither pulp was dried before the experiment began. The pulps were each refined to three different freeness levels to determine the effect of initial freeness on recycled sheet properties. Tests for tear, tensile, zero-span tensile, opacity, brightness, scattering coefficient, absorption coefficient, and porosity were performed on the sheets in order to determine the effects of recycling on those sheet properties. A Kajaani fiber …

Improving Print Quality In Wallpaper By Pigment And Latex Substitution, Christopher L. Stratton

Paper Engineering Senior Theses

The coated paper industry is rapidly changing and improving. Because of increasing demands by consumers, high quality paper at the lowest possible price is at a premium. Because of this paper makers and coaters are continually looking for ways to improve their sheet without increasing cost.

This experiment was designed to test the role which pigment and latex has in influencing the final sheet quality. This was tested in two stages. The first stage examined pigment variations and the second latex variations. In the pigment variation trial, a number 1 high brightness clay was replaced by a structured clay pigment. …

Biology: What One Needs To Know, Ursula Goodenough

Biology Faculty Publications & Presentations

Biology on this planet represents an astonishing experiment in carbon-based chemistry which, over billions of years, has generated billions of species adapted to countless major and minor fluctuations in ecological circumstances. In one sense there is no way to generalize about biology. While biological activities can all be ultimately explained by physical laws (like everything else in the universe), it is the emergent intensely particular properties of organisms that most interest us. This essay represents an attempt to describe some of the more prominent patterns that emerge from the sea of biological particularities, patterns that present many opportunities for religious …

Structural And Functional Analysis Of Secondary Structure Block To Mrna Utilization, Juan Lin

Loma Linda University Electronic Theses, Dissertations & Projects

Experimentally introduced secondary structure, formed by a cis-targeted hammerhead ribozyme in exon 2 two nucleotides dowstream of the 3' splice site of a yeast ACT-E. coli lacZ fusion gene, virtually abolishes splicing in vivo and inhibits B-galactosidase production. This is the first demonstration of the splicing inhibitory effect of secondary structures occurring in exons in the absence of splice site sequestration. Our goal is to understand the mechanism by which utilization of this splice site is impeded. Two cis - and one trans-acting mutations that alleviate the splicing blockage were obtained by screening for restoration of B-galactosidase activity. Both cis …

Diseased Thyrocytes Have Aberrant Communication And Tnf Receptor Secretion, Mary Labue

Loma Linda University Electronic Theses, Dissertations & Projects

Autoimmune diseases are a world-wide health concern and are an intense area of investigation. However, one area of research has been largely ignored. This involves the contribution of the target tissue to the disease process. We hypothesized that cell-cell communication is disrupted by lymphocytic infiltration and advancing fibrosis and this disruption results in altered target cell responses to immune components produced at the site of inflammation, including Tumor Necrosis Factor-alpha (TNF- α).

We have used thyroiditis as our model of autoimmunity and have documented the development of spontaneous thyroiditis in MRL-lpr/lpr mice. We have found aberrant connexin expression in …

Whooping Crane Sightings, August-December 1996, Steven Anschutz

Nebraska Bird Review

Based on observations of the breeding grounds during the summer of 1996, about 170 Whooping Cranes were expected to arrive at the Aransas National Wildlife Refuge in Texas during the fall. The first arrival (two birds) was confirmed on 23 October. A total of 158 birds (143 adults/subadults and 15 young) were wintering at Aransas 1996-97. As of 16 January 1997, six adults and eight subadults, of the number anticipated, had not arrived at the refuge.

The first recorded dates for confirmed observations of migrating Whooping Cranes were 2 August in Canada and 22 September in the United States. The …

This book contains 18 essays based on observations Miss Sherman made on a farm in northeastern Iowa six miles west of the Mississippi River, near McGregor. The essays were given at meetings of scientific societies (she belonged to 15) or were published in their journals, and included such titles as "Feeding Winter Birds" and "Experiments in Feeding Hummingbirds During Seven Summers." She was recognized for her knowledge of birds, and her forceful and pungent wit.

Miss Sherman was born on the Iowa farm in 1853 and died there in 1943. She was an artist and teacher for the first 20 …

Fall Field Report, August-November 1996, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

This fall we received numerous excellent reports from which to compile this summary. Most parts of the state are covered, except the southwest and north central, although many observers at least pass through those areas. A note about details on unusual observations. The new NOU Field Card, which can be ordered by sending a stamped, self-addressed envelope to the NOU Librarian, Univ of Nebraska State Museum, Lincoln, NE 68588-0514, indicates species that need complete documentations, mostly casual and accidental species. However, we realize that information about early and late migration dates, and rarity in the west or east is not …

"Notes On Bird Sightings In Nebraska," From Nebraska Bird Review (December 1996)

Nebraska Bird Review

House Finches. This species has been appearing at my backyard feeders, 10 to 30 feet from our window, for several years, increasing in number each year. They came nearly every day in 1996 except during a period that I associate with post-breeding molt. Numbers varied from one to a maximum of 17 at one time, with 11 counted for the 1996 Christmas Bird Count. We commonly use 7-8 power binoculars to look for a rare Purple Finch. House Finches are noticeably smaller than House Sparrows and slightly larger than American Goldfinches, and feed with both species.

Males have varied in …

The Effects Of Benzo(A)Pyrene And Dimethylbenzanthracene On Cultured Porcine Aortic Endothelial Function, Michelle Lynn Kagey

Masters Theses

Polycyclic aromatic hydrocarbons are environmental contaminants which have been shown to initiate and promote atherosclerosis and carcinogenesis in various animal species. These findings have been based primarily on the increase in incidence and size of smooth muscle cell tumors in these animals were exposed to benzo(a)pyrene (BaP) or dimethylbenzanthracene (DMBA). The endothelium has also been identified as an important mediator in vascular disease and atherogenesis, although the endothelial response to these PAHs has not been investigated. Thus, the focus of this study was on characterization of the endothelial response to BaP and DMBA. Concentration/response relationships for these chemicals were examined, …

Algorithms For Adapting Materialised Views In Data Warehouses, Mukesh Mohania, Guozhu Dong

Kno.e.sis Publications

In this paper we consider the problem of materialised view adaptation in data warehouses. Materialised views are important in data warehousing where they are used to speed up query processing on large amounts of data. User requirements change over time, which may change the definitions of views dynamically. For such situations, the question arises whether the materialised views should be recomputed from scratch for every change in the definition or they should be obtained by adapting old materialised views. Changes to a view definition may be expensive, if the view is recomputed from scratch. Therefore, it is worthwhile to examine …

About The Cellular Tropism Of The Gammaherpesvirus Bovine Herpesvirus Type 4, Fernando A. Osorio, J. A. Galeota-Wheeler, D. E. Reed, O. Lopez

Nebraska Center for Virology: Faculty Publications

We read with interest the recent report by Egyed et al. (4) about the distribution in tissue, in the natural host, of bovine herpesvirus type 4 (BHV-4), a member of the gammaherpesvirus group. Using PCR, those authors were able to trace BHV-4 (Movar strain) in several tissues of experimentally infected cattle (mostly spleen, lung, trachea, and nasal epithelium tissues) at different times, ranging from 3 to 48 days postinfection. The authors also report consistent detection of BHV-4 DNA in what they consider to be a pure population of lymphocytes obtained from peripheral blood of the BHV-4- infected cattle, and then …
