Their research, first reported in the 1980 paper, led them to propose a correlation between geographic areas with low sunlight levels and colon cancer deaths.
To examine seasonality of pregnancy hypertension rates, and whether they related to sunlight levels around conception.
This reference photovoltaic device, placed in the same lighting conditions than the module under test, allows the measurement of the sunlight levels through the monitoring of the maximum power of these devices.
By cross-checking this data against a database, the app provides information about the health of plants, when and how much to water them, and whether they should be moved to change sunlight levels.
Renewable energy poses a challenge to the grid when shifts in wind speeds or sunlight levels create short-term fluctuations that throw off the supply-demand balance.
Short-term variations in temperature and sunlight levels also have the most consistent effect across the different fields and seasons tested.
16 Brazil extends from the equatorial latitudes in the north to the temperate latitudes in the south, with a large variation in sunlight levels across the country.
Colon cancer incidence and mortality rates tend to be higher in areas with low winter sunlight levels, and lower in sunny areas.
For example, certain genes that responded to increases in sunlight in the absence of drought responded to both sunlight levels and the shortage of water when a drought occurred.
We hypothesized that active tuberculosis cases diagnosed in Australia would display seasonality in regions further from the equator but less so in the tropics and that this seasonality would manifest as increased tuberculosis activity several months after nadir sunlight levels.
