Further study on level ice resistance and channel resistance for an icebreaking vessel

International Journal of Naval Architecture and Ocean Engineering, 2016
In this paper, further research is carried out to investigate the resistance encountered by an icebreaking vessel travelling through level ice and channel ice at low speed range. The present paper focuses on experimental and calculated ice resistances by

Coupled regional climate–ice-sheet simulation shows limited Greenland ice loss during the Eemian [PDF]

Climate of the Past, 2013
During the last interglacial period (Eemian, 130–115 kyr BP) eustatic global sea level likely peaked at > 6 m above the present-day level, but estimates of the contribution of the Greenland Ice Sheet vary widely.

Wave interactions with circular ice ridge embedded in level ice

Cold Regions Science and Technology, 2018
Abstract The present study examines the wave interactions with a circular elastic body trapped within a thin cover of sea ice of substantial extent. This configuration is an idealization of an ice ridge embedded in a field of level ice. The ice cover and ice ridge are both modeled as thin elastic plates. Two independent approaches are used. The first

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

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.

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).

Land Ice and Sea Level Rise: A Thirty-Year Perspective [PDF]

Oceanography, 2011
The present-day assessment of contributions to sea level rise from glaciers and ice sheets depends to a large degree on new technologies that allow efficient and precise detection of change in otherwise inaccessible polar regions.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Numerical Simulation for the Collision Between Side Structure and Level Ice in Event of Side Impact Scenario

Latin American Journal of Solids and Structures
With the opening of the Northern Sea for international shipping routes, various vessels prefer to use this option to reach Europe as distance is significantly reduced if a ship is sailing through this route.

A scaling approach to project regional sea level rise and its uncertainties [PDF]

Earth System Dynamics, 2013
Climate change causes global mean sea level to rise due to thermal expansion of seawater and loss of land ice from mountain glaciers, ice caps and ice sheets.

Review of research on ice loading of offshore structures in level ice fields

Zhongguo Jianchuan Yanjiu, 2021
The physical and mechanical properties of sea ice and the failure modes of ice sheets significantly affect the ice loading of offshore structures. This paper first introduces the physical and mechanical characteristics of sea ice, then describes the ...
