Abstract	Many landslides can cause significant damage to infrastructure, property, and human life. To study landslide structure and processes, geophysical techniques are most productive when employed in combination with other survey and monitoring tools, such as intrusive sampling. Here, the integration of electrical resistivity tomography (ERT) and seismic refraction tomography (SRT) methods is used to assess landslides in Thungsong district, Nakhon Si Thammarat, the south of Thailand, where is a hilly and seasons of prolonged rainfall region. The 2D cross-plot analysis of P-wave velocity and resistivity values obtained by these two methods is introduced to identify potential landslide-prone zones in this region. The results of the 2D cross-plot model reveal detailed image of the subsurface conditions, highlighting areas of low P-wave velocity (lower than 600 m/s) and low resistivity (lower than 600 Ωm). These areas are indicative of weak zone and are potential to be sliding materials. Moreover, an intrusive sampling data from boreholes is also used for the calibration and validation geophysical data with geological data. This can improve the accuracy of landslide assessment and develop effective mitigation strategies to reduce the risk of landslides in this area. In addition of the 2D cross-plot, the volume of sliding material is also determined from the difference of the surface and slipping plane elevations. The volume calculation of sliding material is roughly 33447.76 m

Abstract	Gamma-rays from naturally occurring radionuclides are a major component of background radiation. They are an important tool for geology and are also important for radiation protection. In this paper we use over a quarter of a million geochemical measurements of concentrations of potassium, thorium and uranium in soils and in stream sediments to estimate outdoor gamma-ray dose rates across Great Britain. The soil concentrations are generally at a depth of 5-20 cm with some at 35-50 cm. Soil measurements will give spatially relatively precise estimates, but as soil data are not available for much of Scotland, stream sediment data are used there. Kriging methods are used to estimate surface concentrations of K, Th and U and dose rates are imputed from these concentrations. Our results are compared with measurement surveys of both outdoor and indoor gamma-ray dose rates. Recently there has been interest in exploring the carcinogenic risks of low dose radiation by investigating associations between childhood cancer rates and doses from natural background gamma radiation. To achieve adequate statistical power, such studies must be so large that it is impractical to assess exposures by direct measurements in the homes of study subjects. Instead the exposures must be modelled. The results presented here will be an important input to such work.

Abstract	Oxygen store management underlies dive performance and is dependent on the slow heart rate and peripheral vasoconstriction of the dive response to control tissue blood flow and oxygen uptake. Prior research has revealed two major patterns of muscle myoglobin saturation profiles during dives of emperor penguins. In Type A profiles, myoglobin desaturated rapidly, consistent with minimal muscle blood flow and low tissue oxygen uptake. Type B profiles, with fluctuating and slower declines in myoglobin saturation, were consistent with variable tissue blood flow patterns and tissue oxygen uptake during dives. We examined arterial and venous blood oxygen profiles to evaluate blood oxygen extraction and found two primary patterns of venous hemoglobin desaturation that complemented corresponding myoglobin saturation profiles. Type A venous profiles had a hemoglobin saturation that (a) increased/plateaued for most of a dive's duration, (b) only declined during the latter stages of ascent, and (c) often became arterialized [arterio-venous (a-v) shunting]. In Type B venous profiles, variable but progressive hemoglobin desaturation profiles were interrupted by inflections in the profile that were consistent with fluctuating tissue blood flow and oxygen uptake. End-of-dive saturation of arterial and Type A venous hemoglobin saturation profiles were not significantly different, but did differ from those of Type B venous profiles. These findings provide further support that the dive response of emperor penguins is a spectrum of cardiac and vascular components (including a-v shunting) that are dependent on the nature and demands of a given dive and even of a given segment of a dive.

Abstract	Adipose tissue mobilization increases circulating fatty acid (FA) concentrations, leads to increased hepatic FA uptake, and influences hepatic metabolism. Our objective was to trace carbon flux through metabolic pathways in primary bovine neonatal hepatocytes challenged with FA, and to examine the effect of FA challenge on oxidative stress. Primary bovine neonatal hepatocytes were isolated from 4 Holstein bull calves and maintained for 24 h before treatment with either 0 or 1 mM FA cocktail. After 21 h, either [1-

Abstract	The periparturient period for dairy cows is a metabolically dynamic time period where the cow is adjusting from gestation to the onset of lactation. Metabolic disorders such as ketosis, hypocalcemia, and fatty liver occur during this time; however, tools to diagnose these diseases on-farm is limited. The need for compact metabolite quantification devices that can quantify metabolites on farm from whole blood samples is warranted. The purpose of this study was to validate a portable blood analyzer (PBA) by analyzing metabolites on privately owned dairy farms in southcentral Wisconsin. Additional tests were completed to determine if plasma metabolite quantification was similar to whole-blood quantification. Two phases were conducted on two separate farms to complete these analyses and data were analyzed by Bland-Altman plot and correlations. Metabolites quantified from whole blood samples included albumin, alanine and aspartate aminotransferases, β-hydroxybutyrate, blood urea nitrogen, total calcium, cholesterol, creatinine kinase, γ-glutamyl transferase, glucose, magnesium, nonesterified fatty acids, phosphorous, and total protein and were analyzed in the lab after plasma separation to determine gold-standard laboratory concentrations. Across Phase 1 and 2, whole-blood PBA metabolite concentrations resulted in similar results compared to the laboratory assays. For plasma analyzed on the PBA, overall results were positively correlated, but robustness was dependent upon initial validation results indicating some metabolites are suitable for plasma quantification on the device. These results indicate that the PBA is a viable on-farm metabolite quantification tool that will be valuable for on-farm diagnosis of metabolic stress and dysfunction in transition dairy cows.

Conference proceedings ; Online: A new probe for geofluids? Measurements of attenuation anisotropy using instantaneous frequency

Asplet, J. / Wookey, J. / Kendall, J. / Chapman, M.

XXVIII General Assembly of the International Union of Geodesy and Geophysics (IUGG)

Abstract: ... the lithosphere, facilitating rifting (Kendall et al., 2005) and other surface expressions of tectonic processes ...

Abstract	The presence of fluids in closely aligned fractures is important for a range of processes within the Earth. In the near-surface, understanding systems of fluid-filled fractures is important in various applications such as geothermal energy production, monitoring CO 2 storage sites and exploring for metalliferous sub-volcanic brines (e.g., Blundy et al., 2021). In the mantle, melting is an important geodynamic process, exerting control over mantle composition and dynamic processes. Upper mantle melting weakens the lithosphere, facilitating rifting (Kendall et al., 2005) and other surface expressions of tectonic processes. Models of aligned fluid-filled fractures, or inclusions with small aspect ratios, predict both velocity and attenuation anisotropy for shear-waves (e.g., Hudson, 1982; Chapman 2003). Forward modelling shows that attenuation anisotropy is highly sensitive to important fracture properties, such as fracture length and orientation, and can be frequency dependent. Attenuation anisotropy can be observed by measuring shear-wave splitting as the two separated shear-waves experience a different seismic quality factor as they propagate through the anisotropic medium.Measurements of attenuation anisotropy therefore offer a new approach to seismically detect fluids in the subsurface. Here we present a method for measuring attenuation anisotropy using an adaptation of the instantaneous frequency method of Mathenay and Nowack (1995). We explore the potential of this technique using synthetics and make measurements of attenuation anisotropy in SKS data collected at the Yellowknife array, Canada, and at stations across the Main Ethiopia Rift. These results highlight the potential for attenuation anisotropy as a tool to detect geofluids in the subsurface.

Abstract	Background: Cabbage stem flea beetle (CSFB, Psylliodes chrysocephala L.) is a major pest of oilseed rape (OSR, Brassica napus L.) in the UK and low availability of effective chemical control has increased the need for integrated pest management approaches. The risk of OSR to lodging is strongly related to stem strength, however, the impact of CSFB larval tunnelling on stem strength and subsequent risk to stem lodging is unknown. The study investigated this by applying the Generalised Crop Lodging Model to conventionally grown OSR crops scored for varying levels of CSFB larval tunnelling. Lodging risk mitigation strategies including plant growth regulators (PGR) and varying nitrogen regimes were tested under high CSFB larval pressure. Results: Stems of OSR plants were categorised by the proportion of visual damage (< 5%; 5-25%; 26-50%; 51-75%; 75-100%). Stems of 26-50% damage had significantly lower breaking strengths and diameters compared to plants that scored < 5%, with the associated reduction in stem failure windspeed equivalent to an order of magnitude increase in the risk of a lodging event occurring in the UK. PGR use reduced plant height and subsequently lodging risk variably across the sites. Conclusion: Estimating the proportion of stem tunnelling alongside larval pressure may be a useful tool in considering the contribution of CSFB pressure to lodging risk. The research demonstrates that the use of canopy management principles to optimise canopy size through nitrogen management and PGR use may help offset increased lodging risk caused by CSFB tunnelling. © 2024 Society of Chemical Industry.

Abstract	As electric vehicle (EV) sales grow across the world, a common question arises: "what happens to the batteries?" Using expert elicitation, this study identifies the current pathways for retired EV batteries in the United States and Canada and anticipates how the network might evolve in the future. The majority of end-of-life (EOL) EVs are currently managed within the manufacturer and dealership network, but more will enter the independent afterlife market as growing volumes reach EOL out-of-warranty. The interviews indicate that safety, transportation, and accessible information about battery composition and remaining capacity are critical issues across sectors. Participants demonstrated a strong commitment to creating a closed-loop value chain, motivating novel partnerships between recyclers and producers. At the same time, the value of EOL batteries as a material supply source may create competition between recycling and repurposing in the short term. State and federal governments are implementing policies to facilitate access to information and incentivize domestic manufacturing, but compared to other countries, the US lacks a mechanism to ensure that batteries will be collected and recycled. In addition, there is no national tracking system that would provide more robust data on LIB management. Multiple participants noted that the network handles the majority of EOL batteries without significant policy intervention. However, at present, the system depends the economics of reuse and recycling when accounting for the cost of collection and processing, which creates a risk of stranded batteries and/or wasted materials for packs that are lower-value or difficult to access.
