Grassland Research, EarlyView.In this study, we compared two sampling approaches to assess autumn freezing resistance. Our goal was to determine whether the commonly employed cutting method, which disrupts root‐tissue connectivity, provides a valid measure of true freezing resistance.

Influence of Ambient Temperature on the Snow Removal Performance of Self-heating Photovoltaic Panels
Zhileng xuebao, 2020 The removal of snow on photovoltaic (PV) panels has become an important issue in current research on PV panels. In this study, the influence of ambient temperature on the snow removal effect ofself-heating PV panels was studied using the basic principles

Snow mechanics: from snow microstructure to avalanche formation
, 2022 Snow is a fascinating material. Its composition is relatively simple, mainly air and ice, but the arrangement of these components in three dimensions is extremely diverse. This diversity of microstructure, often reduced to discrete snow types, originates from different snowflake growth mechanisms in the atmosphere and the continuous evolution of snow ...

Microscopy Research and Technique, EarlyView.Integrated macroscopic, histological, and ultrastructural analyses revealed five distinct lingual papillae types (filiform, fungiform, conical, foliate, and vallate) in the Anatolian wild boar (Sus scrofa libycus). Mechanical papillae showed marked structural specialization, while gustatory papillae exhibited region‐specific distribution of taste buds.

International Journal of Climatology, EarlyView.Historical observations and bias‐corrected CMIP6 projections reveal intensifying warm extremes, declining cold events and increasingly irregular precipitation patterns across Morocco. Future warming, particularly under SSP5‐8.5, produces an almost linear amplification of heat, aridity and hydrological stress, leading to longer droughts and more intense

International Journal of Climatology, EarlyView.This study investigates summer Greenland atmospheric blocking using the Lagrangian tracking Python package blocktrack applied to ERA5 reanalysis and CMIP6 models. Two types of blocks—upstream (Northern Canada origin) and retrograding (Northern Atlantic origin)—are distinguished, with upstream blocks driving recent observed frequency increasing trends ...

Fracture mechanics of volcanic eruptions [PDF]
, 2009 Seismology is a key tool in the forecasting of volcanic eruptions. The onset of an eruption is often preceded and accompanied by an increase in local seismic activity, driven by fracturing within the edifice.

Crevasses triggered on Pine Island Glacier by drilling through an exceptional melt layer [PDF]
, 2010 The basic theory of crevasse formation suggests that crevasses initiate at or near the surface. However, due to variations in stress with depth, it has been suggested that it is possible for crevasses to initiate at depths of 10–30m.

Experimental study on the unconfined apparent shear strength of compacted snow
Journal of GlaciologyTo address the scarcity of data on compacted snow shear damage under complex conditions, unconfined shear tests were conducted in Northeast China. This study examined apparent shear strength variations with density (300–550 kg·m−3), temperature (−17.4°C ...

Snow particle motion in process of cornice formation [PDF]
The CryosphereSnow cornices are a common snow pattern in cold regions, and their fracture and collapse can easily trigger avalanches. Despite numerous observations and experimental simulations on their formation process, the microscopic mechanism of their initial ...
