Risk, Hazards &Crisis in Public Policy, Volume 14, Issue 4, Page 343-365, December 2023., 2023 Abstract This article traces the historical evolution of risk perception around the Nuclear Research Centre Karlsruhe, Germany, from 1956 to 1997. It does so by targeting the evolution of water‐related risks. Federal hopes in the postwar era that the Nuclear Research Centre would bring progress and prosperity clashed with local values and local ...

ChemCatChem, Volume 15, Issue 13, July 7, 2023., 2023 Cyclohexene oxide alcoholysis: SU‐101 was applied for the Lewis acid‐catalyzed ring‐opening alcoholysis of cyclohexene oxide. Abstract SU‐101 was screened for the acid‐catalyzed ring‐opening alcoholysis of cyclohexene oxide. Results indicated access to open metal sites within SU‐101, a fundamental requirement (Lewis acid Bi+3 sites) for this reaction ...

Ambient Noise H/V Spectral Ratio in Site Effect Estimation in La Mesa de Macaracas, Panama
International Journal of Geophysics, Volume 2022, Issue 1, 2022., 2022 In the last 10 years, the community of La Mesa de Macaracas (central Panama) has experienced considerable aftershocks due to earthquakes of magnitudes up to 5.7 Mw. Although most of the community consists of single‐storey houses, the agricultural development in the region has led to multistorey building projects.

Journal of Agrarian Change, Volume 21, Issue 2, Page 332-355, April 2021., 2021 Abstract This article explores the relations between agricultural production, international migration, wage labour and processes of differentiation among peasant households. It does so based on the analysis of the ejido Jesús María in the northeast of the state of Guanajuato, Central Mexico. The history of this ejido and how Mexican neoliberal policies

Evaporation From Unsaturated Soils as a Function of the Air and Soil Sides of the Land Surface
Water Resources Research, Volume 56, Issue 12, December 2020., 2020 Abstract A theoretical framework for computing the evaporation from unsaturated soils is presented and validated based on laboratory experiments that were conducted in an uncontrolled environment where forcing variables vary in time according to diurnal meteorological cycles. This theory introduces a dimensionless number that controls the ratio between

Hydrodynamic Analysis of the Flow inside the Submerged Entry Nozzle
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 The quality of steel produced by continuous casting depends mainly on the characteristics of the liquid steel flow pattern within the mold. This pattern depends on the flow dynamics of the nozzle that is immersed in liquid steel. This work characterizes the fluid dynamics within two separate submerged entry nozzle models with a square cross section ...

Water Resources Research, Volume 61, Issue 8, August 2025.Abstract Mountains play a critical role in the hydrological cycle by transferring heavy precipitation to lowland aquifers. However, their complexity and remoteness limit our understanding of groundwater flow, particularly the influence of faults. To fill the gap, semi‐idealized 3D numerical models calibrated using the mountain river network and the ...
