Reducing frost heave and salt migration in saline soil foundations of channels in seasonal frozen regions using solidification

open access: yesGuan'gai paishui xuebao
【Objective】Saline soils in seasonal frozen regions are often used as channel foundations but are prone to frost heave and salt migration, which can compromise structural stability.

CALCULATION OF TANGENTIAL FROST HEAVE STRESSES BASED ON PHYSICAL, MECHANICAL AND STRESS-STRAIN BEHAVIOR OF FROZEN SOIL

open access: yesArchitecture and Engineering, 2017
Development of northern territories opens up new opportunities for social and economic development of the society. However, designing construction facilities in such areas is complicated by special features of the severe climate; frost heave of soils is ...

Non-isothermal transport of multi-phase fluids in porous media. The entropy production [PDF]

open access: yes, 2018
We derive the entropy production for transport of multi-phase fluids in a non-deformable, porous medium exposed to differences in pressure, temperature, and chemical potentials.

Historic disturbance events overruled climatic factors as drivers of ruderal species distributions in the Scandinavian mountains

open access: yesNordic Journal of Botany, EarlyView.
The contemporary interaction of climate and disturbance drives vegetation composition and species distribution shifts, making their respective roles difficult to disentangle. This study describes the long‐term ruderal plant species distributions along the ‘Rallarvägen' in Abisko, subarctic Sweden.

Experimental Study on the Frost Heave Characteristics of Silt Clay Modified With Hydrophobic Nano-ZnO

open access: yesAdvances in Civil Engineering
Silty clay is widely distributed in seasonally frozen zones in China and frequently engages in engineering projects. Nevertheless, it exhibits significant frost susceptibility and generates substantial related freezing damage.

Assessing the performance of protective winter covers for outdoor marble statuary: pilot investigation [PDF]

open access: yes, 2005
Outdoor statuary in gardens and parks in temperate climates has a tradition of being covered during the winter, to protect against external conditions. There has been little scientific study of the environmental protection that different types of covers ...

Effects of Static and Dynamic Loads on Frost Heave Deformation of Coarse-Grained Subgrade Soil in Cold Regions

open access: yesApplied Sciences
With the rapid development of high-speed and heavy-haul railways in cold regions, understanding the influence of external loads on the frost heave behavior of subgrade fillings is of great importance.

Frost Heave Deformation Analysis Model for Microheave Filler [PDF]

open access: yes, 2019
With the rapid development of high-speed railway, high-speed railways pose new requirements on subgrade frost heave deformation control. Microheave in conventional non-frost-heave filler cannot meet the requirements of high-speed railways for high levels

Mathematical model of the zebrafish ventricular cardiomyocyte action potential and calcium transient

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study presents the development and validation of the first biophysically detailed computational model of the zebrafish ventricular action potential (AP). The model is based on a human cardiomyocyte framework and reparameterized using published and newly generated patch‐clamp recordings of zebrafish ionic currents.

Relationships between vegetation patterns and periglacial landforms in northwestern Svalbard [PDF]

open access: yes, 2004
We studied the small-scale vegetation pattern in the high Arctic at Ny Angstromlesund to assess if the plant distribution was related to periglacial landforms.
