Immersion pulmonary edema (IPE) is a condition with sudden onset in divers and swimmers suspected to be due to pulmonary arterial or venous hypertension induced by exercise in cold water, although it does occur even with adequate thermal protection. We tested the hypothesis that cold head immersion could facilitate IPE via a reflex rise in pulmonary vascular pressure due solely to cooling of th...

In this white paper, the warm water direct liquid cooling solution implementation in the CCS cluster solution is described. First, literature review of a range of direct liquid cooling solutions implemented in various competing vendors and their pros and cons are briefly presented. Design choices of datacenter cooling water distribution mechanisms (single loop vs primary/secondary loops), types...

Calcareous nannofossil assemblages recovered from a long, continuous section have been described from the Sarayan region in Lut Block in east Iran. The marine Upper Cretaceous sediments of this section yield medium diverse and well-preserved calcareous nannofossil assemblages. A structural analysis of Upper Cretaceous calcareous nannofloras has revealed 30 nannofossil species. A revised zonatio...

California is suffering from a serious drought and the future of turfgrass and other landscape plants has never been more uncertain. Use of drought tolerant plant species should be at the forefront of water conservation management plans for golf courses and other landscapes. Warm-season or C4 grasses are better adapted to warmer, drier climates and use at least 20% less water compared to cool-s...

[1] There is much uncertainty surrounding the mechanisms that forced the abrupt climate fluctuations found in many palaeoclimate records during Marine Isotope Stage (MIS)-3. One of the processes thought to be involved in these events is the Atlantic Meridional Overturning Circulation (MOC), which exhibited large changes in its dominant mode throughout the last glacial period. Giant piston core ...

We explain the physical basis of a model for small globular proteins with water interactions. The water is supposed to access the protein interior in an “all-or-none” manner during the unfolding of the protein chain. As a consequence of this mechanism (somewhat speculative), the model exhibits fundamental aspects of protein thermodynamics, as cold, and warm unfolding of the polypeptide chain, a...

1. Reproductive fitness is often compromised at the margins of a species' range due to sub-optimal conditions. 2. Set against this backdrop, the Mediterranean's largest loggerhead sea turtle (Caretta caretta) rookery at Zakynthos (Greece) presents a conundrum, being at a very high latitude for this species, yet hosting a high concentration of nesting. 3. We used visual surveys combined with glo...

[1] During the 1997–1998 El Niño event, the average sea surface temperature (SST) in the Taiwan Strait (TWS) in the winter was 1.4 C higher than that of the winter climatological mean. The areal ratio of the warm water ( 2 C above the regional mean) to the cold water ( 2 C below the regional mean) in the TWS increased by 25%while the area of the eutrophic water (chlorophyll a >1 mg m ) was halv...
