Clathrate hydrate crystallization

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Clathrate hydrate crystallization has been an area of interest to chemical engineers from the point of view of crystal structure, thermophysical properties, phase equilibria, kinetics, industrial applications, and environmental (climate change) implications.

Expression, Purification, and Microscopy‐Based Assays for Engineered Recombinant Tyrosinated, Detyrosinated, and Δ2 Human Tubulin

open access: yesCytoskeleton, EarlyView.
ABSTRACT Microtubules are noncovalent polymers assembled from α/β tubulin dimers. Their structure, dynamics and interaction with effectors are regulated through the expression of diverse tubulin isotypes and chemically diverse posttranslational modifications, also known as the “tubulin code.” Understanding the biophysical correlates between tubulin ...

Talin1 Adhesion Morphology and Colocalization With Tensin3 Are Largely Unaffected by Polyacrylamide Substrate Stiffness

open access: yesCytoskeleton, EarlyView.
ABSTRACT Cells sense the stiffness of their extracellular matrix (ECM) and adapt their behavior accordingly. We investigated how ECM stiffness affects the spatial organization of talin1, a key mechanosensitive focal adhesion protein. Using polyacrylamide (PA) hydrogels with tunable stiffnesses (0.2–188 kPa), we analyzed cell morphology, migration ...

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

open access: yesDrug 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.

Northern Eurasia Future Initiative (NEFI): facing the challenges and pathways of global change in the twenty-first century [PDF]

open access: yes, 2017
During the past several decades, the Earth system has changed significantly, especially across Northern Eurasia. Changes in the socio-economic conditions of the larger countries in the region have also resulted in a variety of regional environmental ...

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

open access: yesDevelopmental 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.

Using Metaphorical Models for Describing Glaciers

open access: yesInternational Journal of Science Education, 2014
To date, there has only been little conceptual change research regarding conceptions about glaciers. This study used the theoretical background of embodied cognition to reconstruct different metaphorical concepts with respect to the structure of a glacier.

Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone

open access: yesEcography, EarlyView.
This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.

Spatiotemporal mass-balance variability of Jostedalsbreen Ice Cap, Norway, revealed by a temperature-index model using Bayesian inference

open access: yesAnnals of Glaciology
Jostedalsbreen in western Norway is the mainland Europe's largest ice cap and a complex system of more than 80 glaciers. While observational records indicate a significant sensitivity to climate fluctuations, knowledge about ice-cap wide spatiotemporal ...
