Influence of Different Washing Hair Procedures in the Quantitative Determination of THC and THCCOOH

Drug Testing and Analysis, EarlyView.
Different hair decontamination protocols significantly affect THC quantification, with marked analyte loss—particularly after aqueous‐organic washing—whereas THCCOOH remains stable. These findings highlight the risk of misinterpretation and the need for standardized washing procedures in hair analysis.

The flow of salt glaciers

Geophysical Research Letters, 1979
The flow of salt glaciers is investigated. On the basis of data extracted from published sources, order of magnitude estimates (and probable upper and lower limits) for the stress and strain rate in a salt glacier in Iran are determined. The estimate of strain rate is much larger (by a factor of ∼108) than strain rates predicted by previously ...

Detection of the GH Analogue Redalsomatropin Alfa in Sports Drug Testing: Immunological Approaches and LC‐HRMS/MS

Drug Testing and Analysis, EarlyView.
After evaluating the compatibility of the GH analogue redalsomatropin alfa with approved doping control immunoassays for rhGH, it was implemented into the existing detection method for somatrogon employing affinity purification with GHR‐Fc‐conjugated magnetic beads, tryptic digestion, and LC‐HRMS/MS to allow for a specific and sensitive detection ...

Testing Numerical Models of Glacier Flow [PDF]

Journal of Glaciology, 1979
AbstractThe recent glaciological literature contains a number of numerical simulations of ice-mass flow based on the mass conservation equation. Although rather complex ice masses have been modelled, there has been little discussion of the necessary tests for correct response time and amplitudes in the models. The analytical work of J. F.

Heterozygous Med13l mice recapitulate a developmental growth delay and craniofacial anomalies seen in MED13L syndrome

Developmental Dynamics, EarlyView.
Abstract Background Gene transcription is crucial for embryo and postnatal development and is regulated by the Mediator complex. Mediator is comprised of four submodules, including the kinase submodule (CKM). The CKM consists of MED13, MED12, CDK8, and CCNC.

Sub-regional variability in the influence of ice-contact lakes on Himalayan glaciers

Journal of Glaciology
Ice-contact lakes modify glacier geometry and dynamics by shifting the majority of mass loss from the ice surface to the terminus. Lake-terminating glaciers are known to experience greater thinning rates and higher velocities than land-terminating ...

Geometry and drainage of a retreating glacier overlying and recharging a karst aquifer, Tsanfleuron-Sanetsch, Swiss Alps

Acta Carsologica, 2010
Alpine glaciers store large amounts of freshwater contributing to groundwater recharge during warmer periods, but the inter­actions between glaciers and aquifers have rarely been inves­tigated in detail.

A Novel Multilevel Conceptual Framework for Flood Risk Governance

Environmental Policy and Governance, EarlyView.
ABSTRACT Globally, flood risk is increasing as climate change progresses. Contemporary flood risk management practice often utilises hydrodynamic modelling (for hazard risk assessments), social vulnerability assessments, and risk communications in silo, which fragments evidence‐based decision‐making for effective flood risk management. We hence develop

Using PlanetScope-derived time-series elevation models and orthophotos to track glacier 3D dynamics in mid-latitude mountain regions

GIScience & Remote Sensing
Assessing glacier surface height changes provides crucial insights into glacier mass loss and the impact of climate variability. Remote sensing images play a vital role in providing data points for monitoring.

Earthquake‐triggered avalanche altered glacier flow [PDF]

Eos, Transactions American Geophysical Union, 2012
Landslides are common in areas with mountain glaciers and could affect the movement of glaciers. Shugar et al. used satellite radar imagery and numerical modeling to investigate the effects of earthquake‐triggered avalanches on the Black Rapids Glacier in central Alaska. Three avalanches were triggered there by the 2002 magnitude 7.9 Denali earthquake.
