Rainwater Catchment System Designed For California Polytechnic State University Building 34, Jonah S. Aere
Construction Management
California Polytechnic State University currently receives its water supply from either Whale Rock Reservoir, for distilled water, or pumped from six ground wells, for agricultural use. Although the university’s Agricultural College requires a certain amount of water to grow crops, these demands are often not met due to the lack of water within these underground wells. A rainwater capture system could be constructed to ease the water supply burden which is already depleting, reduce wasted drainage, and maintain a sustainable agricultural water source without being dependent on other locations. This would benefit the institution by reducing imported water thereby saving …

Identifying How Summer Camp Experiences Affect Children’S Environmental Literacy, Quinn Kimbell
Department of Environmental Studies: Undergraduate Student Theses
Ensuring that children are prepared for environmental issues in the future can be aided by building the skill of environmental literacy. A key factor in building this skill is having natural experiences and creating one’s connection and perception of the environment. This paper aims to identify if summer camps increase children’s perception of the environment. This was completed by testing children with an environmental perception survey (Children’s Environmental Perception Scale) before and after attending a summer camp and assessing environmental pollution knowledge through drawing (modified Draw-An-Environment Test). The rural Nebraska summer camp subjected the children to many outdoor experiences, including …

Case Study Of A District-University Partnership: Developing Culturally Responsive Educators In A Rural Setting, Trenice Shauntel Durio
Educational Leadership & Workforce Development Theses & Dissertations
Using a theoretical framework of critical race theory and conceptual frameworks of cultural education, this study explores the intersection of district-university partnerships and culturally responsive education. The purpose of this mixed methods case study was to examine the formulation and outcomes of a district-university partnership established to offer a college level course focused on anti-discrimination, equity and inclusion, and social justice in schools. Using survey data, I explored the relationship between participation in the course and the participants’ self-reflection in the areas of empathic concern and perspective taking, preparation for culturally responsive teaching and equitable practices, and comfortability with discussions …

Assessment Of Novel Protein Ingredient Arthrospira Platensis (Microalgae) And Soybean Genotype Amino Acid And Oil Selection Improvements On Broiler Performance, Savannah Wells Crafton
Graduate Theses and Dissertations
Two experiments were conducted to assess the efficiency of including novel protein ingredient Arthrospira platensis or improved soybean meal in a broiler diet. The first experiment aimed to determine the feeding value of soybean meal produced from varieties of soybeans bred for increased amino acid content (SBAA) improved oil content (SBO) compared to a conventional soybean variety in an ANOVA design fed to Cobb 500 female broilers for 28-42d of age. The SBAA and SBO soybeans contained overall higher amino acid content and lower oligosaccharide content compared to the conventional soybean variety in addition to improved oil quality. The second …

Short-Term Changes Within An Agroforestry System Managed At Three Basal Areas With Fescue Compared To Orchardgrass, Matthew Janorschke
Graduate Theses and Dissertations
Silvopasture practices incorporate forages and woody perennials in the same system in order to create a sustainable system. The main objective of this study was to determine if one of two forage species can be successfully established in order to investigate agroforestry as a management system to promote soil health. Within a bottomland mixed hardwood forest in the Arkansas River Valley, an agroforestry system was established to evaluate three basal areas (determined as the cross-sectional area of trees at breast height) (7, 11.5, and 16 m2/ha) with mounded areas and two forages, tall fescue (Lolium arundinaceum [Schreb.] Darbysh) and orchardgrass …

University of Nebraska-Lincoln
The Impact Of Policy Design On Willingness To Pay For Ecosystem Services From Prairie Strips, Karina A. Schoengold, Badri Khanal, Taro Mieno, Lisa Schulte Moore
Cornhusker Economics
Ecosystem services from farmland conservation are public good benefits. The value of these benefits is primarily measured using methods that determine the willingness to pay (WTP) for those benefits. Prairie strips, a farmland conservation practice, provide ecosystem services such as improved water quality, soil health, and biodiversity (Schulte et al., 2017). The state of Iowa is a major corn producer and contributes significant amounts of nitrogen and phosphorous to the Gulf of Mexico (Alexander et al., 2008). The development of conventional agricultural systems has also resulted in a significant loss of biodiversity, including a dominant land cover of tallgrass prairie. …

In case that persons are trapped underground as a result of shaft and roadway damage due to a major disaster accident in a mine, the most effective way of rescue is to construct the rescue channel in a safely and efficient manner. The rescue channel is divided into the underground and ground types. Building a large diameter rescue channel through the collapsed section is the most direct way if underground construction conditions are available. However, if no underground construction conditions are available or it is prone to secondary disasters, it is necessary to drill small diameter rescue holes on the …

Coal Geology & Exploration
In order to solve the rescue problem of collapsed roadways in coal mines and improve the drilling speed of large-diameter rescue boreholes, the construction method of large-diameter borehole with pipe jacking technology was proposed. Specifically, the collapsed rock mass was crushed and the slag was removed by pushing the connectable pipe joints and cutter heads with the main jacking equipment arranged in the chamber, so as to form a rescue channel composed of jacked pipes at last. A composite cutter head with large opening under the condition of collapsed rock mass was developed, which is composed of 10 cutters, 10 …

The exploitation and utilization of critical metals in coal measures is of great significance to alleviate the shortage of strategic mineral resources in China. In addition to the critical metal germanium (Ge), the low-rank coal from Wulantuga Coal Mine of Shengli Coalfield in Inner Mongolia, China is enriched with the toxic elements Be, F, As, Hg, Sb and W. Considering the extraction and utilization of key metals and environmental protection, the coal in the study area must be washed. As shown in the previous study, flotation is relatively good for the removal of As, Sb and W inWulantuga coal, but …

The hidden dangers of road collapse and underground voids are usually difficult to notice and easy to occur in sudden. They have caused huge losses in people's lives and properties. Therefore, the detection and analysis of road collapse and underground voids are crucial. The ground-penetrating radar (GPR) is the main method for detecting the hidden dangers of urban road collapse currently by virtue of its high accuracy, high efficiency, continuous non-destructiveness and real-time imaging. A convolution type objective function FWI algorithm was proposed to solve the problem of the lower inversion accuracy and practicability caused by the inaccurate estimation of …
