paragraph_text: The basic time periods from which the calendar is constructed are the Martian solar day (sometimes called a sol) and the Martian vernal equinox year, which is slightly different from the tropical year.  The sol is 39 minutes 35.244 seconds longer than the Terrestrial solar day and the Martian vernal equinox year is 668.5907 sols in length (which corresponds to 686.86 days on Earth).  The basic intercalation formula therefore allocates six 669-sol years and four 668-sol years to each Martian decade.  The former (still called leap years even though they are more common than non-leap years) are years that are either odd (not evenly divisible by 2) or else are evenly divisible by 10, producing 6,686 sols per ten years (668.6 sols per year).

paragraph_text: Sweetened potato casserole (Finnish "imelletty perunalaatikko") is a traditional Finnish dish from Päijät-Häme, eaten elsewhere in Finland at Christmastime. It is prepared by letting puréed potatoes, mixed with wheat flour, stand at a temperature of around 50°C (122°F). The amylase in the flour will start to break down the potato’s starches to shorter carbohydrate chains, that is sugars. The temperature cannot exceed 75°C (167°F); otherwise, the amylase molecules will break down. Through this process, the dish gets its distinct sweet flavour; nowadays, however, dark syrup (Finnish "tumma siirappi") can be added to give it sweetness. Dark syrup is made from sugarcane and it's the most common type of syrup in Finland. It has a similar taste to molasses, but is sweeter.

paragraph_text: During the summer growing season, phosphate is at a high level. It has a vital role in the breakdown of the sugars manufactured by chlorophyll. But in the fall, phosphate, along with the other chemicals and nutrients, moves out of the leaf into the stem of the plant. When this happens, the sugar-breakdown process changes, leading to the production of anthocyanin pigments. The brighter the light during this period, the greater the production of anthocyanins and the more brilliant the resulting color display. When the days of autumn are bright and cool, and the nights are chilly but not freezing, the brightest colorations usually develop.
