Moderate Resolution Imaging Spectroradiometer (Modis) Observations Of Cyanobacteria Blooms In Taihu Lake, China, Chuanmin Hu, Zhongping Lee, Ronghua Ma, Kun Yu, Daqiu Li, Shaoling Shang

Marine Science Faculty Publications

A novel approach was used with data from the Moderate Resolution Imaging Spectroradiometer (MODIS) to characterize the intense blooms of cyanobacteria (primarily Microcystis aeruginosa) in Taihu Lake, China's third largest freshwater lake. The approach involves first deriving a floating algae index (FAI) based on the medium‐resolution (250 and 500 m) MODIS reflectance data at 645, 859, and 1240 nm after correction of the ozone/gaseous absorption and Rayleigh scattering effects and then objectively determining the FAI threshold value (−0.004) to separate the bloom and nonbloom waters. By definition, the term “bloom” or “floating algae” refers to bloom where cyanobacteria form …

Wildlife are key components in the ecosystem functions of riparian zones and require consideration in peri-urban planning as well. This study reviews relevant literature to determine the recommended minimum riparian buffer width for maintaining water quality and habitat along Stevens Creek in Lincoln, Nebraska. Only sources that listed a specific purpose related to water quality …

A Potential Plan Of Action For Emerald Ash Borer In Nebraska, Lee Wheeler

Department of Environmental Studies: Undergraduate Student Theses

Abstract Emerald Ash Borer (Agrilus planipennis) (EAB) is an invasive insect pest. It feeds on the cambium tissues of ash tree species. It was first discovered in the United States in 2002 in Detroit, Michigan. Their effects on ash trees are deadly, and it is quickly spreading across the Midwest. Nebraska has not yet been invaded, but confirmed findings continue getting closer and closer. The major problem facing Nebraskans, with regards to EAB, is how to begin preparations to prevent a dramatic economic loss when an infestation does occur. So, to address this problem, I have conducted street and park …

Yellowstone Super-Volcano: Evaluation, Potential Threats, And Possible Effects On Nebraska Citizens Health And Prosperity, Jennie Korgie

Department of Environmental Studies: Undergraduate Student Theses

Abstract Yellowstone National Park is located over a hot spot under the North American tectonic plate and holds a potentially explosive super-volcano that has the ability to cause deadly consequences on the North American continent. After an eruption the surrounding region would see the greatest devastation, covered by pyroclastic deposits and thick ash fall exterminating most all life and destroying all structures in its path. In landscapes of greater distance from the event the consequences will be less dramatic yet still substantial. Records of previous eruption data from the Yellowstone super-volcano show that the ash fall out from the eruption …

Cellulosic Ethanol: The Benefits, Obstacles, And Implications For Nebraska, Cassidee Lin Thompson

Department of Environmental Studies: Undergraduate Student Theses

Abstract Ethanol is a biofuel that has unique capabilities to mitigate global climate change by reducing greenhouse gas emissions while simultaneously supporting rural economies and decreasing the United States’ dependence on foreign oil.

Distribution Of Dioecious Eastern Red Cedar (Juniperus Virginiana) Along An Environmental Gradient In Ogallala, Ne, Taylor Sloey

Department of Environmental Studies: Undergraduate Student Theses

Abstract

The purpose of this research was to study the sex distribution and energy allocation of dioecious Eastern Red Cedars (Juniperus virginiana) along an environmental resource gradient. The trees surveyed were growing in a canyon located at the University of Nebraska’s Cedar Point Biological Research Station in Ogallala, Nebraska. Due to the geography of this canyon, environmental factors necessary for plant growth should vary depending on the tree’s location within the canyon. These factors include water availability, sun exposure, ground slope, and soil nitrogen content, all of which are necessary for carbon acquisition.

Juniperus virginiana is a dioecious conifer. Dioecious …

The Role Of The Ras Superfamily Small G-Proteins In The Proinflammatory Environment Of Rhinovirus-Exposed Monocytic-Lineage Cells, Michael Schreiber

Lawrence University Honors Projects

Rhinoviral infections are a major cause of asthma exacerbations, and though productive rhinovirus infection occurs predominantly in the bronchial epithelial cells of the upper airway, monocytic-lineage cells are implicated in establishing the inflammatory microenvironment observed during rhinoviral asthma exacerbation. It has remained unclear whether small G-protein activation plays a role in establishing this inflammatory microenvironment. The small molecular- weight G-proteins are known to be activated in a variety of cell types upon exposure to a range of viruses. However, it is unclear if small G-protein activation during viral exposure is a byproduct of receptor attachment, is important for viral replication, …

Fire Smoulders In The Veins: Toyen's Queer Desire And Its Roots In Prague Surrealism, Karla Huebner

Art and Art History Faculty Publications

This essay explores Toyen’s development of queer themes and places it in the context of her Prague origins. It first looks at its place within the Prague group’s early erotica, then considers early Czech surrealism in relation to interwar Czech sex reformism, feminism, and homoerotic activism, and finally examines how Toyen’s production of artworks can be seen as enacting her queer desire in a tangible form. In closing, it relates Czech surrealist theory and practice to French surrealist ideas. The article also shows how inter-war Czechs participated in the struggle for sexual minority rights.

Pushing Techniques Used By Midwives When Providing Second Stage Labor Care, Kathryn Osborne

Dissertations (1934 -)

A growing body of evidence suggests that spontaneous pushing during the second stage of labor results in better outcomes than directed pushing, which usually involves repeated use of the Valsalva maneuver. However, birth attendants in the United States (U.S.) continue to use directive methods when caring for women in the second stage of labor. This study used quantitative methods with the Theory of Diffusion of Innovations as a framework to identify and describe the practices used by certified nurse-midwives and certified midwives, practicing in the U.S., when caring for women in second stage labor. Data were gathered using a questionnaire …

Exploring Differences In Teacher Attitudes And Instructional Strategies Between Traditional And Block Schedule High Schools: A Comparison Of Two Large Schools, Jerry Randolph Raines

Dissertations

As schools continue to strive to meet federal testing requirements, many schools have been looking at ways to improve. During the 1990’s many school districts thought they had found the method, tool, or program, with which to accomplish this goal: the block schedule. This study was a comparison of the teaching strategies and attitudes of teachers at two high schools with a block schedule and two high schools with a traditional schedule. The researchers began showing interest in this topic when several local schools decided to abandon the block schedule at their high schools, because of the increased cost associated …

Locked Plate Fixation Of Osteoporotic Humeral Shaft Fractures: Are Two Locking Screws Per Segment Enough?, David J. Hak, Peter Althausen, S J. Hazelwood

Biomedical Engineering

Objective: The purpose of this study was to compare the biomechanical behavior of using two versus three locking screws per bone segment in a cadaveric humerus fracture gap model.

Methods: Six matched pairs of elderly osteoporotic fresh–frozen human cadaveric humerii were used. An eight-hole locking compression plate was placed posteriorly on the humeral shaft and secured with either four or six bicortical locking screws. A 5-mm middiaphyseal gap osteotomy was created to simulate a comminuted fracture without bony contact. Specimens were tested in offset axial compression, four-point anteroposterior bending, four-point medial– lateral bending, and torsion. After the initial testing in …
