development—defining it as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs”—and described how it could be achieved. At the 1992United Nations Conference on Environment and Development(also called the Earth Summit),...
They based their calendars on three natural cycles: the solar day, marked by the successive periods of light and darkness as the earth rotates on its axis; the lunar month, following the phases of the moon as it orbits the earth; and the solar year, defined by the changing seasons that ...
This paper aims to identify the economic factors that significantly affect the demand for and supply of housing in three major cities in Turkey, such as Istanbul, Ankara, and Izmir. This study uses monthly data ranges from January 2010 to December 2020 because of the limited housing price data...
Figure 14 illustrates the major components of the data acquisition equipment. The ultrasonic data acquisition system consists of a computer, an ultrasonic pulse transmitter, a water pool, high-speed data-acquisition, and a probe-motion double-3D-coordinate automatic positioning control system. The ...
This is a major issue if ice sheet evolution is being investigated over long time periods, such as glacial cycles. In addition to adaptive grids, a further improvement in numerical methods is exemplified by the Parallel Ice Sheet Model (PISM). This model uses an approach whereby the ‘shallow...
EM:Good point. So you've referred to these three major trends or megatrends: Transforming Technology, Changing Sociodemographics and Preserving the Earth. I'm going to test your knowledge on this domain, on this area. I've done some more homework and here you will hear a compilation of voi...
Major research findings at the PAP-SO in its first ~20 years of operation include the discovery of seasonal input of detritus to the seabed (Billett et al., 1983), revisions to the midwater carbon budget (Giering et al., 2014), and links between interannual detrital supply and benthic co...
Furthermore, freshwater input from major river systems in the region may play a role in the observed changes. Conversely, the steric components, especially the thermosteric, are crucial in explaining interannual variability. This is supported by a strong correlation (r = 0.79) between the ...
•Sustained severe Se depletion in the past oceans correlates closely with three major mass extinction events.•These represent periods of Se depletion >1.5-2 orders of magnitude lower than current ocean levels.•Se depletion may have thus been one of several factors in these complex extinction...
Major similarities in community composition became only apparent at higher taxonomic levels and comprised Alpha-, Gamma- and Deltaproteobacteria, as well as Planctomycetes and Acidobacteria (Supplementary Figure 1). tested for Skagerrak) needed time to adjust to elevated acetate concentrations (Figure 3)...
