Determining the Optimal Water Storage Depth of Apple Orchards in the Chinese Loess Plateau: Balancing Soil Desiccation Mitigation, Plant Utilization, and Engineering Construction

Land Degradation &Development, EarlyView.
ABSTRACT Deep‐rooted plantations are central to dryland ecological restoration, yet their long‐term cultivation drives widespread deep soil desiccation, threatening ecosystem sustainability. While artificial water replenishment is a key deep soil desiccation mitigation strategy, the depth‐dependent positional effect of stored water on eco‐hydrological ...

Evaluation of a non‐radioactive rapid test for determination of serum progesterone in South American camelids

Veterinary Record, EarlyView.
Abstract Background Determination of the serum progesterone (P4) concentration is of high importance in reproductive medicine and may be applied for diagnosing pregnancy in South American camelids. P4 measurements in alpacas and llamas are usually performed using immunoassays, which are time consuming and require appropriate expertise of laboratory ...

Migration of tritium in the components of the natural environment

Вісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. Екологія
Formulation of the problem. Tritium formed as a result of natural or man-made processes is included in migration flows depending on the forms of its presence – gaseous (NT), aqueous (NTO) and organically bound (OZT).

Quantum‐Level Influences on Enzyme Reactions and Their Ripple Effects on Biological Phenomena

Advanced Physics Research, Volume 5, Issue 9, September 2026.
Because living organisms are ultimately composed of atoms and molecules, quantum‐mechanical effects are expected to contribute to biological phenomena. Quantum biology seeks to elucidate life processes from a quantum‐mechanical perspective. This review discusses how quantum‐level effects, including quantum tunneling, may propagate from enzymatic proton‐

Synthesis and Characterization of Tritium‐Labeled Neuropeptide Y Y5 Receptor Ligands Derived From CGP71683A

Archiv der Pharmazie, Volume 359, Issue 8, August 2026.
From a synthesized series of 2,4‐diaminoquinazoline‐type Y5R ligands, three were prepared as tritium‐labeled compounds and characterized by saturation equilibrium binding at HEC‐1B‐hY5R cells. [3H]32 was further applied in a competition binding assay. High non‐specific binding of the radioligands prompted investigation of material‐dependent adsorption.

Improving the Reliability of Groundwater Recharge Estimates by Modelling Stable Water Isotope Transport in Soils

Hydrological Processes, Volume 40, Issue 7, July 2026.
Three 1‐D unsaturated zone models (HYDRUS‐1D with isotope fractionation) were calibrated with volumetric water content (θ) alone versus θ and δ18O δ2H from soil water. Adding isotopes constrains the parameter spaces and reproduces isotope profiles despite θ extremes, and reveals heterogeneous recharge in semi‐arid Tamil Nadu, South India.

Variability and Complexity of Environmental Drivers on Catchment Transit Times Across Space: A Systematic Review

WIREs Water, Volume 13, Issue 4, July/August 2026.
Environmental drivers influence or modulate transport processes that finally determine catchment transit times. TTD represents transit time distribution; MTT is the mean transit time; and Fyw means young water fraction. ABSTRACT Catchment transit time, the time water takes to travel from precipitation to streamflow, is a key diagnostic of how ...

Comparing Piston Flow and Dispersion Models for the Age of Groundwater Collected Through Very Short Screens

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract In previous groundwater dating studies involving samples collected through probes with very short screens, the tracer analysis has assumed the groundwater to have an age range so narrow that it can reasonably be considered a single age (a piston flow interpretation).

Karst Vadose Zone Hydrology Explored Through Cave Drip Water Dynamics: The Roles of Soil, Epikarst and Climate

Hydrological Processes, Volume 40, Issue 6, June 2026.
Cave drip rate monitoring in Nova Grgosova Cave reveals three types of drip sites: (1) predominantly constant, (2) seasonally varying and (3) mostly constant with occasional sharp increases. The observational data coupled with one‐dimensional water‐balance model demonstrates that evapotranspiration and soil–epikarst storage, rather than precipitation ...
