Level ice interactions with multi-legged offshore structures
Инженерно-строительный журнал, 2017 The task of determining the total ice load from drifting level ice floes on 3- and 4-legged structures, widely used in the development of offshore oil & gas fields, was considered in the article.

Snow metamorphism: a fractal approach
, 2010 Snow is a porous disordered medium consisting of air and three water phases: ice, vapour and liquid. The ice phase consists of an assemblage of grains, ice matrix, initially arranged over a random load bearing skeleton.

Peridynamic Simulation of the Penetration of an Ice Sheet by a Vertically Ascending Cylinder
Journal of Marine Science and EngineeringThe vertical ice breaking of marine structures in ice-covered areas involves the deformation and failure of an ice sheet. Different from the existing conventional scenarios where the ice sheet is used as a transportation and support medium, the damage to

A comparison of regression models for the ice loads measured during the ice tank test
Brodogradnja, 2023 To evaluate the time-domain positioning performance of arctic marine structures, it is necessary to generate an ice load appropriate for the current position and heading of the structure. The position and orientation angle of a floating body continuously

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Ice loads acting on a model podded propeller blade (OMAE2005-67416) [PDF]
, 2007 With the increase in popularity of podded propulsors and arctic navigation, understanding the interaction between a podded propulsor and ice has become more important.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Finite Element Analysis of Small Scale Continuous Calving [PDF]
, 2013 Ice shelves are floating ice masses, which are sensitive to climate changes. The main mechanisms for the mass loss of ice shelves around Antarctica are basal melting and calving.
