Bioavailability and Biodegradability of Dissolved Organic Nitrogen Originated From Municipal and Animal Wastewater
(North Dakota State University, 2015)
Due to the increased concern on dissolved organic nitrogen (DON) in surface waters, it is necessary to understand the biodegradability and bioavailability of DON in point and non-point sources. In this study, algae and ...
Quantification and Characterization of Particulate Matter Generated from Unpaved Roads in the Oil Development Area of Western North Dakota
(North Dakota State University, 2016)
Western North Dakota, USA is experiencing particulate matter (PM) emissions, especially coarse (PM10) and fine (PM2.5), due to heavy traffic on unpaved roads from rapid oil development. Particulate matters may affect human ...
Thermal, Physico-Mechanical and Degradation Characteristics of Compatibilized Biodegradable Biopolymers and Composites
(North Dakota State University, 2017)
Due to negative effects of petroleum-based plastic waste on environment, a significant consideration is given to biopolymers as sustainable alternatives. However, incompetence in technology and cost prevent the applications ...
Combined Effect of Densification and Pretreatment on Cellulosic Ethanol Production
(North Dakota State University, 2012)
Biomass densification enhances material stability, improves flowability, and decreases both handling and transportation costs. The effect of densification, before or after pretreatment, was tested to determine the effect ...
Developing a New Powered Seed Delivery System with Constant Seed Release Speed Using Two Confronting Belts
(North Dakota State University, 2018)
Seed delivery devices are aimed to carry seeds down to open furrow that might affect uniformity of plant stand and spacing. The objective of this study was to develop and evaluate a new seed delivery system utilizing a ...
Incorporation of Subsurface Drainage and Subirrigation Into the Checkbook Method
(North Dakota State University, 2016)
The highly variable climate of the Red River Valley of the North brings both flood and drought conditions, leading to an interest in subsurface water management systems (WMS). These subsurface WMS can drain excess water ...
Sweet Corn Production with Different Mulches, Varieties, and Planting Dates in North Dakota
(North Dakota State University, 2016)
Sweetcorn is a high value crop that can grow almost anywhere given the right temperature conditions. In North Dakota those conditions are not always met. Using mulch increases the soil temperature. Early planting will have ...
Infield Biomass Bales Aggregation Logistics and Equipment Track Impacted Area Evaluation
(North Dakota State University, 2017)
Efficient bale stack location, infield bale logistics, and equipment track impacted area were conducted in three different studies using simulation in R. Even though the geometric median produced the best logistics, among ...
Remediation of Feedlot Nutrients Runoff by Hydroponic Treatment and Electrolysis Process
(North Dakota State University, 2014)
Intensive livestock farming in feedlot producing large amounts of manure and wastewater. Hydroponic and electrolysis treatments were studied for the remediation of nutrients from feedlot runoff. Water hyacinth, water ...
Evaluation of Storage Techniques to Preserve Fermentable Sugars from Sugar Beets for Ethanol Production
(North Dakota State University, 2012)
New sugar beet varieties may qualify as an advanced biofuel feedstock in the U.S., but new alternatives to conventional pile storage are necessary to preserve fermentable sugars and allow yearlong beet ethanol production. ...
