Sulfur dioxide (also sulphur dioxide) is the chemical compound with the formula SO
2. At standard atmosphere, it is a toxic gas with a pungent, irritating, and rotten smell. The triple point is 197.69 K and 1.67 kPa. It is released naturally by volcanic activity.
Sulfur dioxide was used by the Romans in winemaking when they discovered that burning sulfur candles inside empty wine vessels kept them fresh and free from vinegar smell.

Scheduling in pulp mills
The pulp process involves many production stages, usually coupled with intermediate storage tanks. As each stage has a different reliability and bottlenecks may vary from day to day, scheduling a pulp mill needs to take into account these bottlenecks and the probability of a disturbance or breakdown. Each stage also may have different decision variables, such as steam / water / chemical input, etc.

"I became obsessed with the Valentine’s letter, trying to figure out how
to fold it. Finally, after hours of folding, I did. Here are some
pictures I had taken after the experiments. What I didn’t know was that
the letters were called Victorian puzzle purses. If it is too hard to
figure out how to fold via the images above, here is some further
explanation from the origami resource center,"

"Religion from O.Fr. religion "religious community," from L. religionem (nom. religio)
"respect for what is sacred, reverence for the gods,"
"obligation, the bond between man and the gods"
is derived from the Latin religiō, the ultimate origins of which are obscure.
One possibility is an interpretation traced to Cicero,
connecting lego "read", i.e. re (again) + lego in the sense of
"choose", "go over again" or "consider carefully".
Modern scholars such as Tom Harpur and Joseph Campbell favor the derivation from ligare
"bind, connect", probably from a prefixed re-ligare, i.e. re (again) + ligare or
"to reconnect,""

"Aluminium (or aluminum; see spelling differences) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal. Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal in the Earth's crust.
It makes up about 8% by weight of the crust, though it is less common
in the mantle below. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals. The chief ore of aluminium is bauxite.
Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates.
Despite its prevalence in the environment, no known form of life uses aluminium salts metabolically. In keeping with its pervasiveness, aluminium is well tolerated by plants and animals. Owing to their prevalence, potential beneficial (or otherwise) biological roles of aluminium compounds are of continuing interest." Wikipedia
The Holy Graal ("The Holy Grail is a dish, plate, stone, or cup that is part of an important theme of Arthurian literature. According to legend, it has special powers, and is designed to provide happiness, eternal youth and food in infinite abundance.") can be metaphored as
an aluminium cup filled with sand.
