Authors: Li, X.; Advisor: -; Participants: Yang, X,; Ma, Y.; Hu, G.; Hu, X. (2018) - The Qinghai Lake Basin Critical Zone Observatory (QLBCZO) is being established to study alpine hydrology, carbon–water processes, and ecological functions on the northeastern QTP. Previous studies in the QLBCZO mainly focused on ecohydrologic processes and the water budget. Currently, the QLBCZO is designed to integrate state‐of the‐art observation techniques (such as including deep coring, ground‐penetrating radar, electrical resistance tomography, isotope technique, and remote sensing) and frontier modeling approaches to investigate: (i) the three‐dimensional architecture of the subsurface environment (vegetation–soil–rock–microbial community) as well as the carbon and water storage...

While Berberian (BBR) is an effective antivirus and possesses potentials of suppressing CVB replication, Zeng et al. explored a structural modification of BBR by incorporating a substituted primary amine enhance antiviral potency and safety. Based on data set from Zeng et al., we attempted to propose a QSAR model that can predict the bioactivity of unknown compounds as anti-CVB1.

Authors: Nex, F.; Stöcker, C.; Advisor: -; Participants: - (2017) - Within the past years, the development of high-quality Inertial Measurement Units (IMU) and GNSS technology and dedicated RTK (Real Time Kinematic) and PPK (Post-Processing Kinematic) solutions for UAVs promise accurate measurements of the exterior orientation (EO) parameters which allow to georeference the images. Whereas the positive impact of known precise GNSS coordinates of camera positions is already well studied, the influence of the angular observations have not been studied in depth so far. Challenges include accuracies of GNSS/IMU observations, excessive angular motion and time synchronization problems during the flight. Thus, this study assesses the final geometric accuracy...

Authors: Gogos, A.; Advisor: -; Participants: Wielinski, J.; Voegelin, A.; Kammer, F.V.D.; Kaegi, R. (2020) - Based on the assumption that the industrially used Ce is free of (most) other REE, we estimated the fraction of anthropogenic Ce in the sludges based on individual Ce/REE ratios. For the individual sludges the anthropogenic contributions were very variable (10–100%) but consistent fractions were obtained for individual sludges when calculated based on Ce/Dy (dysprosium), Ce/Er (erbium) and Ce/Eu (europium) ratios. Electron microscopy analysis of sludges dominated by anthropogenic Ce revealed that the Ce was mostly contained in nanoscale particles devoid of elements characteristic of Ce-bearing minerals. Thus, anthropogenic Ce contents derived from REE patterns may be used to validate ...

Authors: Hayat, F; Advisor: -; Participants: Zarebanadkouki, M.; Ahmed, M.A.; Buecherl, T.; Carminati, A. (2020) - We show how to use neutron radiography to quantify the rate of water efflux from the roots to the soil. Maize (Zea mays L.) plants were grown in a sandy substrate 40 cm deep. Deuterated water (D2O) was injected in the bottom wet compartment, and its transport through the roots to the top dry soil was imaged using neutron radiography. A diffusion–convection model was used to simulate the transport of D2O in soil and root and inversely estimate the convective fluxes. Overnight, D2O appeared in nodal and lateral roots in the top compartment. By inverse modeling, we estimated an efflux from lateral roots into the dry soil equal to jr = 2.35 × 10−7 cm−1. A significant fraction of the redis...

(2021) - Rare Earth Elements (REEs) are used in increasing amounts in technical applications and consumer products. However, to date, the contribution of industrial sources to the loads of individual REEs in wastewater streams have not been quantified. Here, we determine the REE contents in sludge collected from 63 wastewater treatment plants (WWTPs) across Switzerland. To quantify the industrial fraction of individual REEs in the sewage sludge, we develop two complementary approaches, based on REE ratios and REE pattern fitting. Unspecific (background) inputs, with REE patterns similar to the averaged REE pattern of soils collected across Switzerland, dominate the REE budget of most WWTPs.

Authors: Tian, H.; Advisor: -; Participants: Wei, C.; Lai, Y.; Chen, P. (2018) - In analyzing the phase transition and water migration processes in multiphase porous systems, it is helpful to properly evaluate the unfrozen capillary water content and adsorptive water content, respectively. In this study, an innovative procedure was developed to determine the total, adsorptive, and capillary water contents in frozen soils based on the nuclear magnetic resonance (NMR) technique. We found a threshold value of the proton spin–spin relaxation time, T2, that separates the unfrozen pore water into two distinct regimes: the adsorptive regime for small T2 values and the capillary regime for large T2 values. We showed that the relationship between adsorptive (or capillary) ...

Authors: -; Advisor: -; Participants: - (2016) - As the new National 3D Elevation Program (3DEP) prepares to provide high-resolution lidar coverage for continental United States, Hawaii, and the territories, it is important to consider that terrain information captured in elevation data are pixel-based instead of feature-based. Referencing 3DEP data for semantic access and inferencing requires the transcription of pixels into accessible features. Indeed, accessing and inferencing terrain features renders them more operational for long-term national mapping. Much progress has been made in transcribing pixels into terrain features using Geographic Object-Based Image Analysis (GEOBIA), as compared to traditional, pixel-based image anal...

Authors: Conley, G.; Advisor: -; Participants: Beck, N.; Riihimaki, C.A.; Tanner, M. (2020) - We ran a series of laboratory and field experiments to identify clogging mechanisms and quantify infiltration performance declines as a function of sediment loading. The results show rapid initial declines of infiltration rate, primarily due to accumulation of material at the bottom of the infiltration BMP. The performance decline trajectories were sensitive to BMP geometry, with BMPs that had greater lateral infiltration surface area declining less quickly. We integrated these experimental results to a spatially distributed stormwater model to illustrate how they can be used to predict BMP performance declines over time and assess cost trade-offs. Results will be used to adapt algori...

Authors: Loo, S.E.; Advisor: -; Participants: Zebarth, B.J.; Ryan, M.C.; Forge, T.A.; Cey, E.E. (2019) - This study quantified the magnitude and timing of NO3–N leaching under a commercial red raspberry field over 30 mo (October 2010–March 2013) using passive capillary wick samplers installed below the root zone at three row locations (irrigated row, nonirrigated row, and alley) after the critical period of field renovation and replanting. Substantial NO3–N leaching (240 kg N ha−1) during the first year of monitoring was attributed to the effects of field renovation (including autumn chopping and incorporation of raspberry canes and soil fumigation and spring poultry broiler manure application) in the year prior to the initiation of monitoring. Lower NO3–N leaching (80 kg N ha−1) occurre...

Authors: Turunen, M.; Advisor: -; Participants: Hyväluoma, J.; Heikkinen, J.; Keskinen, R.; Kaseva, J.; Koestel, J.; Rasa, K. (2019) - The imaged porosities of the materials differed significantly with decomposition degree. Drying curve observations showed that drying of the materials occurred in three phases with (i) large changes in the air‐filled porosity in the matric potential range 0.2 to 3.2 kPa, (ii) clearly smaller changes at 3.2 to 312 kPa, and (iii) large changes at 312 to 1585 kPa, comparable to the change in the wet end of the drying curves (0.2–3.2 kPa). The aeration of the materials was sufficient for plant growth in the second and third phases, where the amount of easily available water was low. This challenges the suitability of the materials under conditions without regular irrigation. The 3D imagin...

Authors: Kuhl, A.S.; Advisor: -; Participants: Kendall, A.D.; Van Dam, R.L.; Hyndman, D.W. (2018) - In this study, we developed and tested a coupled hydrogeophysical inversion approach that uses electrical resistivity data to estimate soil hydraulic, petrophysical, and root dynamic parameters. This builds on prior research that used either a coupled hydrogeophysical inversion to estimate soil hydraulic parameters only, or a hydrological inversion to estimate root distribution or root water uptake parameters. Our results indicate that under the conditions tested, this approach accurately captures root water dynamics and soil hydraulic parameters. This opens up opportunities to noninvasively image a variety of root distributions and soil systems, better understand the dynamics of RWU ...
