Corn And Soybean Response To Wastewater-Recycled Phosphorus Fertilizers, Shane Ylagan 2020 University of Arkansas, Fayetteville

Corn And Soybean Response To Wastewater-Recycled Phosphorus Fertilizers, Shane Ylagan

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

The ability to recycle phosphorus (P) from wastewaters could provide a sustainable, continuous source of P that might also help protect surface water quality from P enrichment. The mineral struvite (MgNH4PO4·6H2O) is an understudied material that can be created from Pcontaining wastewater and has been shown to have agricultural fertilizer value. The objective of this study was to evaluate the effects of electrochemically precipitated struvite (ECST), chemically precipitated struvite (Crystal Green; CG), diammonium phosphate (DAP), monoammonium phosphate (MAP), rock phosphate (RP), and triple super phosphate (TSP) on corn (Zea mays) and soybean (Glycine max) response in a 79-day greenhouse ...

Wetland inventory maps are essential information for the conservation and management of natural wetland areas. The classification framework is crucial for successful mapping of complex wetlands, including the model selection, input variables and training procedures. In this context, deep neural network (DNN) is a powerful technique for remote sensing image classification, but this model application for wetland mapping has not been discussed in the previous literature, especially using commercial WorldView-3 data. This study developed a new framework for wetland mapping using DNN algorithm and WorldView-3 image in the Millrace Flats Wildlife Management Area, Iowa, USA. The study area has several ...

A growing need exists to identify, implement, and research alternative methods to communicate with, educate, and engage youth about science, in order to increase science literacy and knowledge of future societal decision-makers. Electronic field trips (EFTs) are one channel of non-formal communication and education that have been introduced in agricultural and natural resources to reach youth audiences with science-based information in real-time. EFTs can be conducted in several different ways due to the proliferation of video production and web-streaming technologies. The following professional development article offers science communication professionals and scientists a detailed model and specific steps to develop and ...


Student Emotional Responses To Different Communication Situations, Rachel E. Hendrix, Carley C. Morrison 2020 West Virginia University

Student Emotional Responses To Different Communication Situations, Rachel E. Hendrix, Carley C. Morrison

Journal of Applied Communications

Communication and emotion are closely linked. Emotions experienced while communicating with others can affect one’s message both verbally and nonverbally. This study asked participants to identify the emotions they experienced when communicating with groups of different sizes. These emotions were drawn from, and displayed upon, the Circumplex Model of Affect, a figure developed by Posner, Russell, and Peterson (2005). This model divides 16 emotions into quadrants that lie along two axes: pleasantness and emotional arousal. Results show that as audience size increases, speakers’ emotions become more unpleasant, more highly aroused, and more variable overall. Prior research indicates that these ...


Community Development In The Time Of Covid-19, Daniela Mattos 2020 University of Nebraska-Lincoln

Community Development In The Time Of Covid-19, Daniela Mattos

Cornhusker Economics

The global pandemic has driven the whole country into an unprecedented crisis. As the months passed and the death toll climbed, the pandemic did some-thing else: it unveiled deep inequities within the country. Those getting sick and dying were disproportionately low-income racial and ethnographic minorities, most of them essential workers. According to the lat-est data from the Center for Disease Control and Prevention, the virus has overly affected Black people and Latinos (https://www.cdc.gov/coronavirus/2019-ncov/covid-data/covidview/index.html). Communities of color are also over represented among essential workers who are generally unable to work from home ...


Distribution And Activity Patterns Of Large Carnivores And Their Implications For Human–Carnivore Conflict Management In Namibia, Summer Fink, Richard Chandler, Michael Chamberlain, Steven Castleberry, Shannon Glosenger-Thrasher 2020 University of Georgia

Distribution And Activity Patterns Of Large Carnivores And Their Implications For Human–Carnivore Conflict Management In Namibia, Summer Fink, Richard Chandler, Michael Chamberlain, Steven Castleberry, Shannon Glosenger-Thrasher

Human–Wildlife Interactions

Human–wildlife conflicts (HWCs) are increasing globally and contributing to the decline of wildlife species. In sub-Saharan African countries such as Namibia, most of the suitable land has been or is currently being converted to crop and livestock production to support income or subsistence agriculture. These changes in land use often incur increased levels of HWCs because of crop and livestock depredation by native species. To quantify livestock predation risks posed by carnivores in Namibia, we deployed 30 trail cameras on a 6,500-ha farm in the Khomas region of Namibia from May to July 2018. We developed occupancy models ...

Assumptions (Mistakes) That Parents Make With Estate Plans, Allan Vyhnalek 2020 University of Nebraska-Lincoln

Assumptions (Mistakes) That Parents Make With Estate Plans, Allan Vyhnalek

Cornhusker Economics

The main goal of many parents when writing their estate plan is for their children to continue to be a family. With this goal in mind, parents make many assumptions to “keep the peace” when planning their estate. If the family has a key fight then family activities, like holiday gatherings, no longer happen. Let’s look at these assumptions and make some observations about each. The overall goal is to think through our actions with the intent that the family stays together.

Without an estate plan, the assets are divided ac-cording to the laws of the state of Nebraska ...

Proof-Of-Concept Of High-Pressure Torrefaction For Improvement Of Pelletized Biomass Fuel Properties And Process Cost Reduction, Bartosz Matyjewicz, Kacper Świechowski, Jacek A. Koziel, Andrzej Białowiec

Agricultural and Biosystems Engineering Publications

This paper provides a comprehensive description of the new approach to biomass torrefaction under high-pressure conditions. A new type of laboratory-scale high-pressure reactor was designed and built. The aim of the study was to compare the high-pressure torrefaction with conventional near atmospheric pressure torrefaction. Specifically, we investigated the torrefaction process influence on the fuel properties of wooden-pellet for two different pressure regimes up to 15 bar. All torrefaction processes were conducted at 300 °C, at 30 min of residence time. The initial analysis of the increased pressure impact on the torrefaction parameters: mass yields, energy densification ratio, energy yield, process ...

Background: The impact of extreme changes in weather patterns in the economy and humanity welfare are some of the biggest challenges that our civilization is facing. From the anthropogenic activities that contribute to climate change, reducing the impact of farming activities is a priority, since its responsible for up to 18% of greenhouse gases linked to such activities. To this end, we tested if the ruminal and fecal microbiomes components of 52 Brazilian Nelore bulls, belonging to two experimental groups based on the feed intervention, conventional (A) and byproducts based diet (B), could be used as biomarkers for methane (CH ...
