Recent energy balance of Earth
A recently published estimate of Earth’s global warming trend is 0.63 ± 0.28 W/m, as calculated from ocean heat content anomaly data spanning 1993–2008. This value is not representative of the recent (2003–2008) warming/cooling rate because of a “flattening” that occurred around 2001–2002. Using only 2003–2008 data from Argo floats, we find by four different algorithms that the recent trend ran...
متن کاملThermoregulation, energy balance, regulatory peptides: recent developments.
Energy balance of the body is determined mainly by the function of various hypothalamic and brainstem nuclei, according to a complex interaction between the regulation of body temperature (actual metabolic rate vs. heat loss) and regulation of body weight (metabolic rate vs. food intake). The direct effect of central anabolic neuropeptides (neuropeptide Y, orexins, melanin concentrating hormone...
متن کاملEarth ’ S Global Energy
W eather and climate on Earth are determined by the amount and distribution of incoming radiation from the sun. For an equilibrium climate, OLR1 necessarily balances the incoming ASR, although there is a great deal of fascinating atmosphere, ocean, and land phenomena that couple the two. Incoming radiant energy may be scattered and reflected by clouds and aerosols or absorbed in the atmosphere....
متن کاملSeasonal Control of Mammalian Energy Balance: Recent Advances in the Understanding of Daily Torpor and Hibernation.
Endothermic mammals and birds require intensive energy turnover to sustain high body temperatures and metabolic rates. To cope with the energetic bottlenecks associated with the change of seasons, and to minimise energy expenditure, complex mechanisms and strategies are used, such as daily torpor and hibernation. During torpor, metabolic depression and low body temperatures save energy. However...
متن کاملRAM analysis of earth pressure balance tunnel boring machines: A case study
Earth pressure balance tunnel boring machines (EPB-TBMs) are favorably applied in urban tunneling projects. Despite their numerous advantages, considerable delays and high maintenance cost are the main disadvantages these machines suffer from. Reliability, availability, and maintainability (RAM) analysis is a practical technique that uses failure and repair dataset obtained over a reasonable ti...
