BACKGROUND The intestine is extremely sensitive to ischemic preservation and reoxygenation injury. Current vascular perfusion and cold storage with University of Wisconsin (UW) solution neglect the intestinal lumen and the ongoing mucosal metabolism during hypothermia. This study was designed to test the effects of luminal preservation with an alternative preservation solution in addition to th...

Abstract In the Ross Sea sector of Antarctica, periodic large-scale marine ice-sheet fluctuations since mid-Miocene are recorded by drill core and seismic data, revealing a dynamic response to past increases in temperature atmospheric CO2. adjacent, predominantly ice-free McMurdo Dry Valleys (MDVs), preserved terrestrial landscapes reflect persistent cold conditions have been interpreted as ind...

The palaeoceanographic studies are largely limited by poor carbonate preservation in high-latitude regions. To improve our knowledge this key area, we studied a sediment core (ANT32-RA05C) terms of paleomagnetic and 230 Th dating geochemical properties, collected from the continental slope Ross Sea, Antarctica. two major results as follows: 1 ) sedimentation rate based on isotopes is 1.37 cm/ky...

This study investigates how variations in Arctic sea ice and sea surface conditions influence δ18O of presentday Arctic precipitation. This is done using the model isoCAM3, an isotope-equipped version of the National Center for Atmospheric Research Community Atmosphere Model version 3. Four sensitivity experiments and one control simulation are performed with prescribed sea surface temperature ...

Miners in Australia frequently perform physically demanding work under high ambient temperatures and humidity, often whilst wearing personal protective equipment, leading to heat-related illnesses. This study investigated effects of replacing 100% and 50% sweat losses with 5% carbohydrate liquid or ice-slurry solution on core temperature during simulated mining conditions. Five randomized tread...

Ice duration has shortened and the ice-off date has become earlier for Lake Mendota from 1905 to 2000 as air temperatures have warmed and snowfall has increased. In addition, the ice record has cyclic components at i...

HARMONIE-AROME is a convection-permitting non-hydrostatic model that includes the multipurpose SURFEX surface model. It is developed for high resolution (1–3 km) weather forecasting and applied in a number of regions in Europe and the Mediterranean. A version of HARMONIE-AROME is also under development for regional climate modelling. Here we run HARMONIE-AROME for a domain over Greenland that i...

Areas of dark ice have appeared on the Greenland ice sheet every summer in recent years. These are likely to have a great impact on the mass balance of the ice sheet because of their low albedo. We report annual and geographical variations in the bare ice and dark ice areas that appeared on the Greenland Ice Sheet from 2000 to 2014 by using MODIS satellite images. The July monthly mean of the e...
