Nebraska Water Center: Faculty Publications

Carbamazepine (CBZ) is the most frequently detected pharmaceutical residues in aquatic environments effluent by wastewater treatment plants. Batch and column experiments were conducted to evaluate the removal of CBZ from ultra-pure water and wastewater treatment plant (WWTP) effluent using raw zeolitic tuff (RZT) and surfactant modified zeolite (SMZ). Point zero net charge (pHpzc), X-ray diffraction (XRD), X-ray fluorescence (XRF), and Fourier Transform Infrared (FTIR) were investigated for adsorbents to evaluate the physiochemical changes resulted from the modification process using Hexadecyltrimethylammonium bromide (HDTMA-Br). XRD and FTIR showed that the surfactant modification of RZT has created an amorphous surface with new alkyl …

The MALINA oceanographic campaign was conducted during summer 2009 to investigate the carbon stocks and the processes controlling the carbon fluxes in the Mackenzie River estuary and the Beaufort Sea. During the campaign, an extensive suite of physical, chemical and biological variables were measured across seven shelf-basin transects (south-north) to capture the meridional gradient between the estuary and the open ocean. Key variables such as temperature, absolute salinity, radiance, irradiance, nutrient concentrations, chlorophyll a concentration, bacteria, phytoplankton and zooplankton abundance and taxonomy, and carbon stocks and fluxes were routinely measured onboard the Canadian research icebreaker CCGS Amundsen and from a …

High biogenic silica (BSi) concentrations occur sporadically in lake sediments throughout the world; however, the processes leading to high BSi concentrations vary. We explored the factors responsible for the high BSi concentration in sediments of a small, high-latitude subarctic lake (Lake 850). The Si budget of this lake had not been fully characterized before to establish the drivers of BSi accumulation in this environment. To do this, we combined measurements of variations in stream discharge, dissolved silica (DSi) concentrations, and stable Si isotopes in both lake and stream water with measurements of BSi content in lake sediments. Water, radon, and …

School of Earth, Environmental, & Marine Sciences Faculty Publications

As the effects of anthropogenic climate change become more severe, several approaches for deliberate climate intervention to reduce or stabilize Earth’s surface temperature have been proposed. Solar radiation modification (SRM) is one potential approach to partially counteract anthropogenic warming by reflecting a small proportion of the incoming solar radiation to increase Earth’s albedo. While climate science research has focused on the predicted climate effects of SRM, almost no studies have investigated the impacts that SRM would have on ecological systems. The impacts and risks posed by SRM would vary by implementation scenario, anthropogenic climate effects, geographic region, and by ecosystem, …

Deepnec: A Novel Alignment-Free Tool For The Characterization Of Nitrification-Related Enzymes Using Deep Learning, A Step Towards Comprehensive Understanding Of The Nitrogen Cycle, Naveen Duhan Apr 2021

Deepnec: A Novel Alignment-Free Tool For The Characterization Of Nitrification-Related Enzymes Using Deep Learning, A Step Towards Comprehensive Understanding Of The Nitrogen Cycle, Naveen Duhan

Student Research Symposium

Abstract: Nitrification is an important microbial two-step transformation in the global nitrogen cycle, as it is the only natural process that produces nitrate within a system. The functional annotation of nitrification-related enzymes has a broad range of applications in metagenomics, agriculture, industrial biotechnology, etc. The time and resources needed for determining the function of enzymes experimentally are restrictively costly. Therefore, an accurate genome-scale computational prediction of the nitrification-related enzymes has become much more important.In this study, we developed an alignment-free computational approach to determine the nitrification-related enzymes from the sequence itself. We propose deepNEC, a novel end-to-end feature selection and …


Pyseqrna: An Automated Python Package For Advanced Rna Sequencing Data Analysis And Annotation, Naveen Duhan Apr 2021

Pyseqrna: An Automated Python Package For Advanced Rna Sequencing Data Analysis And Annotation, Naveen Duhan

Student Research Symposium

Abstract: With the advent of Next-Generation Sequencing (NGS) technologies, numerous data is being generated every day, however, streamlined analysis remains a big hurdle to efficiently use the technology. A large number of algorithms, statistical methods, and software tools have been developed in recent years to perform the individual analysis steps of various NGS applications. Some NGS applications data analysis procedures are therefore very complex, requiring several program tools to be downloaded for their various processing steps. There is a significant room for the development of scalable computing environments that link the individual software components to automated workflows to efficiently and …


Translating -Omics Big Data: Comprehensive Understanding Of Host-Pathogen Interactions To Control Bacterial Blight In Alfalfa Using Computational Approaches, Raghav Kataria Apr 2021

Translating -Omics Big Data: Comprehensive Understanding Of Host-Pathogen Interactions To Control Bacterial Blight In Alfalfa Using Computational Approaches, Raghav Kataria

Student Research Symposium

Plant infectious diseases are a major threat to the crops, owing to economic losses to the agriculture industry worldwide. Molecular interactions between the host and pathogen play a critical role in understanding the basis of pathogenesis. Majority of the Pseudomonas syringae strains are known to cause frost injury in plants, amongst which, P. syringae pv. syringae ALF3 is asserted to be a causal organism of bacterial stem blight in Medicago sativa (alfalfa). We elucidated the genome-scale host-pathogen interactions (HPIs) between alfalfa and P. syringae using two intense computational approaches: interolog (homology-based) and the domain-based method (based on 3D structure of …

Is Mitigation Of Drought Stress By Zinc Oxide Nanoparticles Driven By A Nano-Specific Mechanism Or Mitigation Of Micronutrient Deficiency?, Justin Deakin Apr 2021

Is Mitigation Of Drought Stress By Zinc Oxide Nanoparticles Driven By A Nano-Specific Mechanism Or Mitigation Of Micronutrient Deficiency?, Justin Deakin

Student Research Symposium

It has been reported that zinc oxide (ZnO) nanoparticles (NPs) can promote drought tolerance in crops when used as soil amendments. However, many of these experiments were conducted in Zn-deficient growth media with no comparison to currently available Zn fertilization methods, making it unclear if the benefits from adding ZnO NPs were caused by a nano-specifc mechanism or simply by the mitigation of a micronutrient deficiency. A review of the literature shows that of 12 published experiments considering the effects of ZnO NPs on plant health, 5 out of 6 studies that did not include a comparison to currently available …
