The cosine of the hour angle (cos(h)) is used to calculate the solar zenith angle. At solar noon, h = 0.000 so cos(h) = 1, and before and after solar noon the cos(± h) term = the same value for morning (negative hour angle) or afternoon (positive hour angle), so that the Sun is at the same altitude in the sky at 11:00AM and 1:00PM solar time.

If a planet rotates prograde, and the sidereal day exactly equals the orbital period, then the formula above gives an infinitely long solar day (division by zero). This is the case for a planet in synchronous rotation ; in the case of zero eccentricity, one hemisphere experiences eternal day, the other eternal night, with a "twilight belt ...
Alberta, Yukon, Northwest Territories, and Nunavut have no territorial sales taxes, so only the GST is collected. Other provinces have either a Provincial Sales Tax (PST) or the Harmonized Sales Tax (HST), which is a single, blended combination of the GST and PST.
The Winkler index uses the standard method of calculating growing degree-days in viticulture and is based on using a base temperature of 50 °F (10 °C) with no upper temperature cut-off. The first issue is that 50 °F (10 °C) is not likely the best base temperature even though it is the most commonly used value.
Australian GST revenue is collected by the Federal government, and then paid to the states under a distribution formula determined by the Commonwealth Grants Commission. Australians pay tax for the provision of healthcare , education , defense, roads and railways and for payments to welfare, disaster relief and pensions . [ 1 ]

Fst values between European populations. The fixation index (F ST) is a measure of population differentiation due to genetic structure.It is frequently estimated from genetic polymorphism data, such as single-nucleotide polymorphisms (SNP) or microsatellites.
The Government of Canada collects about $5 billion per year in excise taxes on gasoline, diesel, and aviation fuel [21] as well as approximately $1.6 billion per year from GST revenues on gasoline and diesel (net of input tax credits).
