Design And Testing Of A Multi-Depth Soil Temperature Sensor Array Intended As A Candidate Irrigation Scheduling Tool, Lillian Glaeser Aug 2020

Design And Testing Of A Multi-Depth Soil Temperature Sensor Array Intended As A Candidate Irrigation Scheduling Tool, Lillian Glaeser

Biological and Agricultural Engineering Undergraduate Honors Theses

A crucial measure in the advancement of water conservation and sustainable agricultural strategies is increasing efficiencies of irrigation systems. Because of the lack of availability of affordable, durable, and scalable soil moisture monitoring devices, this thesis proposes a low-cost, multi-depth soil temperature sensor array as a candidate for monitoring soil moisture content and guiding farmer’s irrigation scheduling. Propagation of diurnal temperature waves through soil is dependent on the thermal diffusivity of the soil, which can be determined by examining temperature waves at different soil depths. Thermal diffusivity is dependent on several factors, though, in undisturbed soil, water has the ...

Low-Temperature Pyrolysis Of Municipal Solid Waste Components And Refuse-Derived Fuel—Process Efficiency And Fuel Properties Of Carbonized Solid Fuel, Kacper Swiechowski, Ewa Syguła, Jacek A. Koziel, Paweł Stepien, Szymon Kugler, Piotr Manczarski, Andrzej Białowiec

Agricultural and Biosystems Engineering Publications

New technologies to valorize refuse-derived fuels (RDFs) will be required in the near future due to emerging trends of (1) the cement industry’s demands for high-quality alternative fuels and (2) the decreasing calorific value of the fuels derived from municipal solid waste (MSW) and currently used in cement/incineration plants. Low-temperature pyrolysis can increase the calorific value of processed material, leading to the production of value-added carbonized solid fuel (CSF). This dataset summarizes the key properties of MSW-derived CSF. Pyrolysis experiments were completed using eight types of organic waste and their two RDF mixtures. Organic waste represented common morphological ...


Application Of An Ultrasonic Sensor To Monitor Soil Erosion And Deposition, Jessica E. Johnson May 2020

Application Of An Ultrasonic Sensor To Monitor Soil Erosion And Deposition, Jessica E. Johnson

Biological Systems Engineering--Dissertations, Theses, and Student Research

While erosion and deposition are naturally occurring processes, these processes can be accelerated by human influences. The acceleration of erosion causes damage to human assets and costs billions of dollars to mitigate. Monitoring erosion at high resolutions can provide researchers and managers the data necessary to help manage erosion. Current erosion monitoring methods tend to be invasive to the area, record low frequency measurements, have a narrow spatial range of measurement, or are very expensive. There is a need for an affordable monitoring system capable of monitoring erosion and deposition non-invasively at a high resolution. The objectives of this research ...


Using Infrared Radiometry Thermometer For Irrigation Management Of Dry Edible Beans In Western Nebraska, Isabella Presotto Possignolo May 2020

Using Infrared Radiometry Thermometer For Irrigation Management Of Dry Edible Beans In Western Nebraska, Isabella Presotto Possignolo

Biological Systems Engineering--Dissertations, Theses, and Student Research

Proper irrigation management requires farmers to determine the right timing and amount to irrigate. Soil water sensors are one of the most popular sensor-based approach used by farmers to decide when and how much to irrigate. However, installation and retrieval of soil water sensors require excavation of soil and can be challenging. Other than soil water sensors, there are plant-based water stress monitoring technologies that are less soil disturbing such as infrared radiometry thermometer (IRT). Using canopy temperature measured from IRT, researchers can calculate thermal-based indices such as crop water stress index (CWSI) for many crops around the world. Yet ...

Reducing Dissolved Phosphorus In Stream Water May Not Influence Estimation Of Sediment Equilibrium Phosphorus Concentrations, Eleanor Henson May 2020

Reducing Dissolved Phosphorus In Stream Water May Not Influence Estimation Of Sediment Equilibrium Phosphorus Concentrations, Eleanor Henson

Biological and Agricultural Engineering Undergraduate Honors Theses

The potential for stream sediments to adsorb or release phosphorus (P) depends on the equilibrium P concentration (EPC), which is the water column P concentration where P is neither (net) adsorbed nor released from the sediments. Current methods of measuring EPC in streams include adding known P concentrations to stream water, mixing with fresh sediments, and allowing the mixture to reach equilibrium through P sorption. Sediment EPC is usually calculated as the x-intercept of the linear relationship between initial P concentrations and P absorbed by the sediments. However, the x-intercept is often an extrapolation past the known data set (i ...


Design Of A Deep Flow Technique Hydroponic System And An Elementary Education Module For Tri Cycle Farms, Cady Rosenbaum May 2020

Design Of A Deep Flow Technique Hydroponic System And An Elementary Education Module For Tri Cycle Farms, Cady Rosenbaum

Biological and Agricultural Engineering Undergraduate Honors Theses

Hydroponics is an agricultural technique in which plants are grown without soil and are instead grown in water systems that include nutrients and other growth-supporting media. Hydroponic systems typically reside inside, so that the system can be fully controlled by the grower by manipulating the temperature and amount of light the plants receive. The benefits of growing plants using hydroponics include: the amount of water used is reduced, it is less labor to grow organic produce with an indoor system, less space used, and it allows for growing food anywhere. Tri Cycle Farms is planning for the construction of a ...

Removal Of Fluoride From Mine Water Via Adsorption For Land-Applied Soil Amendment, Ethan Phan, Adrian Damian, Kevin Le, Mary Johnson, Courtney Golman, Michelle Dopp, Jacqueline Payne

Chemical Engineering Undergraduate Honors Theses

The process of mining minerals and elements from ores and rocks creates acid rock drainage (ARD). This drainage is water that contains heavy metals and minerals that can be dangerous for human consumption or damaging to the environment. The mining industry has employed various water treatment methods to prevent these metals and minerals from being discharged into water sources such as ponds, lakes, and streams. Currently, the most used treatment process in the mining industry is a cost-effective high-density sludge (HDS) process. This method reduces the concentration of metals and elements with the use of lime/limestone. However, the concentration ...

Providing Sustainable Power Through Renewable Energy For Developing Communities In Central America, Elizabeth Topping

Biological and Agricultural Engineering Undergraduate Honors Theses

Rural electrification through an expansion of the power grid into remote villages in Central America is a development that is still years away. Using renewable energy technology, access to electricity is available even in the most remote areas of the world. These individual power grids are also called “microgrids.” Creating microgrids in rural areas provides the people living there with access to power they did not have before. With this newfound access to power, these communities can expand their access to education, using computers or mobile devices. They can power lights, refrigerators, and other devices to continue development.

Evaluating Evapotranspiration Values In Rwanda While Using The Turc And Hargreaves-Samani Equations., Elizabeth Uwase, Derek M. Heeren, Lameck O. Odhiambo

UCARE Research Products

Evapotranspiration (ET) is an important component of the hydrologic cycle and involves the exchange of water between the surrounding water bodies, soil, crop surfaces, and the atmosphere. Crop growth and yields are largely affected by the rate of ET, especially in semi-arid areas where the rate of ET is high and rainfall is not sufficient and reliable to add more water into the soil for crop use. Solar radiation, relative humidity, air temperature, rainfall, and wind velocity are some of the meteorological factors that affect ET. Therefore, this research was aimed at determining ET and its trend across Rwanda using ...

Assessment Of Nanoparticle Accumulation With Dynamic Contrast-Enhanced Magnetic Resonance Imaging, Hunter Miller

Biological Systems Engineering--Dissertations, Theses, and Student Research

Nanoparticle (NP)-based therapeutics promise to improve medicine in multiple areas by increasing target engagement. To date, most research has focused on cancer, aiming to increase uptake using the enhanced permeability and retention (EPR) effect. Despite pre-clinical success in proof-of-concept studies, understanding of the fundamental interactions between NP and biological systems that govern outcomes remains incomplete. To realize the potential of NPs for cancer therapeutics, and to expand their application into other diseases, the roles physicochemical properties play in NP uptake must be better understood. Some investigations have been performed into the effects of size and surface charge on uptake ...

  • During a Foreign Animal Disease (FAD) outbreak, it is critical that people, equipment, and vehicles do not inadvertently move the disease-causing agent between premises (i.e., locations where animals are housed or otherwise handled).
  • To prevent this potential transmission, a cleaning and disinfection (C&D) station must be established at the clean/dirty line on infected premises, and everything going on or off the premises pass through it.
  • Without this critical precaution, more viruses may remain in the environment and cause potential infection of other premises and herds; thus, making FAD containment a challenge.
