Abstract:
The soil sorption coefficient (Kd) of glyphosate mainly controls its transport and fate in the environment. Laboratory-based analysis of Kd is laborious and expensive. This study aimed to test the feasibility of visible near-infrared spectroscopy (vis–NIRS) as an alternative method for glyphosate Kd estimation at a country scale and compare its accuracy against pedotransfer function (PTF). A total of 439 soils with a wide range of Kd values (37–2409 L kg−1) were collected from Denmark (DK) and southwest Greenland (GR). Two modeling scenarios were considered to predict Kd: a combined model deve

Abstract. A global constant value of the extinction coefficient (Kd) is usually specified in lake models to parameterize water clarity. This study aimed to improve the performance of the 1-D freshwater lake (FLake) model using satellite-derived Kd for Lake Erie. The CoastColour algorithm was applied to MERIS satellite imagery to estimate Kd. The constant (0.2 m−1) and satellite-derived Kd values as well as radiation fluxes and meteorological station observations were then used to run FLake for a meteorological station on Lake Erie. Results improved compared to using the constant Kd value (0.2

The vertical diffuse attenuation coefficient Kd (PAR) is used for calculating the euphotic zone, the first optical depth that is important for primary productivity models. Currently, Kd (PAR) can be estimated using an irradiometer or a Secchi disk (SD). The main objective of this work is to define a model that can be applied to a wide range of optical marine conditions to estimate Kd (PAR) by SD. We used irradiance profiles and SD depth (ZSD) from 679 stations in various marine regions. Three parametric models were developed, and their statistical performance was evaluated in view of previous

Beach protection is vital to reduce the damage to shorelines and coastal areas; one of the artificial protections that can be utilized is the tetrapod. However, much damage occurred when using a traditional tetrapod due to the lack of stability coefficient (KD).

The modification seeks to hold the drag force from the wave and offer a good interlocking in between the tetrapod. This research applied physical model test research using

The dominating factors affecting sorption of per- and polyfluoroalkyl substances (PFAS) remain subject of research and debate. Traditionally, distribution coefficients (e.g., Kd and KOC) are used to calculate the fractionation of the contaminant between soil and water, to estimate leaching and subsequently the risks it imposes reaching water reservoirs. Research has aimed to establish the sorption mechanisms for PFAS but, due to the complexity of interactions between the substance specific physiochemical properties and geochemical sorbent characteristics, it has shown to be a complicated task.

Abstract:
This study investigates the relationship between inflation and gross domestic product (GDP) growth in Germany over the period 2012-2022. The objective of this study was to investigate the relationship between inflation and its potential influence on GDP growth. The conducted research reveals a weak positive linear relationship (correlation coefficient of 0.18) between inflation and GDP growth, suggesting that increased inflation corresponds to a moderate increase in GDP growth. This study underscores the importance of ongoing monitoring of inflation and its influencing factors, as it contribut

Abstract:
A computer code named Fitting for Diffusion Parameters (FDP) based on Mathematica 6.0 has been developed for modeling through- and out-diffusion experiments. FDP was used to determine the diffusion coefficients (De) and the rock capacity factors (α) for tritiated water (HTO) and 22Na+ and the distribution coefficient (Kd) of 22Na+ in Opalinus Clay (OPA). The values for De and α were obtained by fitting the results of experimental data of both transient and steady-state phases to the analytical solution of accumulated activity. The quality of the parameters De and α was tested by using them as

Abstract:
As HPHT activity continues to grow and well conditions become more severe, more advanced analysis methods are required. Thermal/heat transfer and structural Finite Element Analyses (FEA) play a fundamental role in the design of subsea equipment for HPHT application. The objective of this study is to evaluate the effect of seawater convective heat transfer coefficient on design verification of a subsea drilling connector in the HPHT environment (bore pressure more than 15,000 psi, and/or bore temperature more than 300°F). The design verification work contains the elastic-plastic assessments inc

Abstract:
Abstract Considering the effects of poroelasticity in oil flow models becomes the modeling regarding formation evaluation and reservoir engineering more realistic. It occurs because poroelastic parameters, e.g., in situ overburden stress, σob, Young's modulus, E and Biot's coefficient, α have a fundamental role in reservoir depletion response. This paper develops a new perturbative solution for the nonlinear hydraulic diffusivity equation (NHDE) in Biot's effective stress-sensitive infinite-acting-oil reservoirs. For this modeling, the NHDE is perturbed until the first-order using the dimensio

Abstract:
This report summarizes the results of eight field Jet Erosion Tests (JETs) performed on Benbrook Dam, TX. The results from these tests will be used by the U.S. Army Corps of Engineers, Fort Worth District, in assessments of the erosion resistance of the Benbrook Dam with regards to possible overtopping by extreme flooding. The JETs were performed at four different locations, i.e., two locations at the lowest crest elevation and two locations at the mid-slope face of the downstream embankment. Variations in estimated critical hydraulic shear stress and erosion rate values may have been caused b
