Phenology is the science of natural occurrences, yearly events like the first snow, the first blooming of hepatica and the arrival of the first whippoorwill.
We used natural-log transformed yearly meanatural-log transformedling.
The radiation intensity at each RSA examination was 50 kilovoltage (kV) and 20 milliampere × second (mAs), and estimations from previous studies [11] with an equivalent experimental setup reveal that the total effective radiation dose throughout the study is only approximately 1% of the yearly natural background radiation.
Our outcome shows that Guangzhou has the highest and best yearly natural-ventilation potential, followed by Shanghai, Beijing and Urumqi, which is quite distinct from that of Yang et al. From the analysis, it is clear that our model evaluates the NVP values more consistently with the outdoor climate data and thus reveals the true value of NVP.
According to researchers at the Global Footprint Network, an ecological-economics think tank, American consumerism probably crossed the line into unsustainability meaning that U.S. per-capita consumption exceeded the natural resources theoretically available yearly to each world citizen sometime between 1940 and 1960.
In this article it is shown empirically that ballasted bridges in cold climates can exhibit a step-like variation of their natural frequencies as the yearly season changes.
Infrastructural data must become a natural component of the yearly routine data flow in a HIS as the melioration of facility infrastructure has the potential of improving health services [ 5, 9, 13] thus contributing to the final goal of better health of the population [ 17].
We carried out a quasi-Poisson time series regression analysis, with yearly all-cause natural deaths as the outcome, and the main exposures of interest being annual-heat and annual-cold.
The world's largest miner said it had achieved yearly production records in natural gas, aluminium, copper, nickel, iron ore and other commodities.
As for the oyster reefs, we need to think of them as an investment: rebuild the natural capital and harvest only the yearly interest, leaving the principal untouched.
