The Effect Of A Sheet Tension Controller On The Productivity Of A Papermachine, Timothy J. Rummel Nov 1998

The Effect Of A Sheet Tension Controller On The Productivity Of A Papermachine, Timothy J. Rummel

Honors Theses

This thesis proposal outlines a project in which the efficiency of a papermachine is increased by controlling the tension through the dryer section. The controlled tension is expected to reduce wet end breaks and to decrease the steam demand of the dryer section. The experiment will be run by placing a laser positioning sensor above the open draw of a papermachine and monitoring the position of the draw until an optimum height of the paper has been determined. Then an automatic drive controller will be connected to the wet end drive to maintain a constant draw height and the machine …


Characterization Of Metal-Regulated Genes In Pseudomonas Fluorescens, Melanie Pearson Aug 1998

Characterization Of Metal-Regulated Genes In Pseudomonas Fluorescens, Melanie Pearson

Honors Theses

One side effect of today's industrialized world is increased levels of heavy metals in the environment. Many of these metals are necessary for biological function as trace elements, but at higher concentrations are toxic. Other metals, such as cadmium, are not beneficial at any level, and have only deleterious effects on living organisms. Cadmium is primarily thought to interfere with normal biological function of proteins. Human exposure to cadmium appears to primarily damage the kidneys, but may also affect the liver, lungs, immune system, and central nervous system. Bacteria, however, have developed several methods for handling toxic heavy metals: cation …

Shrimp Aquaculture: An Analysis Of Its Evolution And Organization; And The Development Of A Shrimp Growth Model, Adam Rana May 1998

Shrimp Aquaculture: An Analysis Of Its Evolution And Organization; And The Development Of A Shrimp Growth Model, Adam Rana

Honors Theses

This paper examines the impetus for the development and subsequent rise of the shrimp aquaculture industry and continues by exploring a model that seeks to improve shrimp farmers' harvests by identifying specific variables affecting shrimp growth. Evidence reviewed from 1980 through today suggest that technological advancements, reduced prices, and increases in both the supply and demand for shrimp are positively associated with the industry's rapid ascent. The introduction of vertically integrated shrimp farms along with the ability for shrimp farmers to differentiate their products are also correlated with the industry's growth. Variables affecting shrimp growth were also studied to determine …

The Effects Of Rose Bengal Application On The Production Of Salicylic Acid In Nahg Tobacco Plants, Nicole Christine Ott Apr 1998

The Effects Of Rose Bengal Application On The Production Of Salicylic Acid In Nahg Tobacco Plants, Nicole Christine Ott

Honors Theses

Plants have the ability to develop resistance to a wide range of pathogens following exposure to a single bacterium, fungus, or virus. This resistance occurs in all tissues, not only those that were previously infected. This mechanisms is termed systemic acquired resistance (SAR). The phenolic compound salicylic acid (SA) has been linked to SAR in tobacco, arabidopsis, and cucumber plants. Oxidative stress also causes SA production, which leads to SAR. An engineered tobacco plant (nahG) that does not have the ability to accumulate SA has been used as a research tool in investigations concerning SA activity. Rose Bengal …


Sustainable Development In The Third World: An Assessment Of The Conservation Actions In South Africa, Brazil, Malaysia, And Madagascar, Carol Rizkalla Apr 1998

Sustainable Development In The Third World: An Assessment Of The Conservation Actions In South Africa, Brazil, Malaysia, And Madagascar, Carol Rizkalla

Honors Theses

As a library research project, this thesis has gone beyond research in the library, and it could not have been possible without the aid of several people. First I must thank the organizations which responded to my request for information: the Center for Environmental Information, the Rainforest Action Network, the World Wildlife Fund, and Conservation International Specifically, Jill McLaughlin in the Communications Department of CI was· most gracious in sending me management plans for parks in Brazil and Madagascar. Carla Langeveld of the WWF, was very helpful during my visit to their library, and subsequently in my request for the …
