One large study by Ben D. Woodand Frank N. Freeman in 1932 paved theway for acceptance in elementary schools.The study included 14,947 children ofelementary-school age in an experimenton the effect of the typewriter on class-room performance (3). The children whohad typing instruction actually spent onlyan hour or two a week at the typewriter,yet at the end of the first year they out-performed the nontyping pupils in read-ing.

Durch die globale Erhitzung wird in Europa das Gebiet, in dem Fichten angebaut werden können, um 50% abnehmen abnehmen. Ein neuer Bericht der internationalen Union der Organisationen zur Erforschung der Wälder zeigt, dass auch andere Baumarten, die als mögliche Alternativen galten, unter den veränderten klimatischen Bedingungen nur schwer überleben. https://www.derstandard.de/story/3000000211551/was-tun-wenn-uns-die-fichte-als-superbaum-wegstirbt

Eine neue Studie der Universität für Bodenkultur beziffert erstmals, wieviel Kohlenstoff zwischen 1900 und 2015 langfristig oder kurzfristig in menschlichen Artefakten wie Gebäuden gespeichert wurde. Die Menge des dauerhaft gespeicherten Kohlenstoffs hat sich seit 1900 versechzehnfacht. Sie reicht aber bei weitem nicht aus, um die globale Erhitzung wirksam zu beeinflussen. Die Möglichkeiten, Boot in Gebäuden zu nutzen, um der Atmosphäre CO2 zu entziehen, werden bisher nicht genutzt. https://www.derstandard.at/story/3000000208522/co2-entnahme-durch-holzbau-ist-bisher-nicht-relevant-fuer-den-klimaschutz

Die nördlichen Wälder Kanadas wurden seit 1976 durch Holzfällen erheblich geschädigt, wie eine neue Studie über zwei Provinzen zeigt. Nicht nur ging der Waldbestand erheblich zurück, die übrig gebliebenen Gebiete sind durch Fragmentierung für den Klimaschutz weniger relevant als die ursprünglichen Wälder. Der Nachhaltigkeitsbegriff der kanadischen Regierung sei vor allem an den Bedürfnissen der Holzindustrie orientiert, stellt der Hauptautor der Studie fest. Experten bezeichnen die Ergebnisse der auch als methodisch wichtig angesehenen Studie als schockierend. https://www.nytimes.com/2024/01/04/world/canada/canada-boreal-forest-logging.html

Many daisy, rabbit, and fox types were first brought together by Lovelock to create a numerical model for biodiversity. In the real world, biological systems are continually being perturbed by the cycles of day and night, the turn of the seasons, changes in the climate, and innumerable other factors. When a Daisy-world in equilibrium is perturbed by the introduction of a herbivore or a sudden change in solar input, a transient burst of different daisy types appears until the system restabilizes, with new types dominant

we found this extraordinary paper from 1951 I think by Goldschmidt Walter Goldschmidt which nobody's read it has 00:29:14 got a very strange title something like a contribution to ethical and philosophical sociology or something which tells you very little about its content but it's about these Californian foragers who live next door to the 00:29:27 highly aristocratic slave keeping fishermen of the northwest coast and what Goldschmidt who was a student of Alfred Kroeber I believe the great sort of Dayan of 00:29:40 California anthropology what he argues there point four point is that these Californian hunter-gatherers actually had a kind of work ethic which is remarkably similar to what Max Weber 00:29:54 classically described as the Protestant work ethic of central and northern Europe
Walter Goldschmidt had a 1951 paper about coastal Californian foragers next to aristocratic slave keeping fishermen. These hunter-gatherers apparently had a work ethic similar to that of Max Weber's Protestant work ethic.
Did these fishermen have totem poles (aka decorated wood
Goldschmidt was a student of Alfred Kroeber. Would he have known or worked with Milman Parry?
Kroeber received his PhD under Franz Boas at Columbia University in 1901, the first doctorate in anthropology awarded by Columbia.

To grow, trees photosynthesize and turn water and carbon dioxide (pulled from the air), into hydrocarbons. A living tree sucks carbon dioxide from the air and locks it into wood as it grows. Even when the tree dies (unless we burn it), the carbon is still locked up in the wood
Cycle of tree's life
-
For a wood fire, ash is primarily composed of metal carbonates and oxides (such as Calcium Carbonate, and Potassium Carbonate), from the compounds in the original wood
Ash - compounds that did not burn
-
As long as there is a source of fuel (and oxygen), the fire will burn
Oxygen keeps the fire alive
-
As the fire gets hotter, more complete combustion occurs, less smoke is produced, and the flames lose the yellow color, turning more blue
As the fire gets hotter:
- more complete combustion
- less smoke
- yellow colour turns into blue
-
yellow flames seen in a fire are the result of incomplete combustion
Yellow flames - incomplete combustion
-
smoke produced (early stages of fire) is unburned carbon
Smoke - unburned
carbon
-
It is the volatile compounds that out-gas from the wood, and eagerly react with oxygen, that are burning, and generate the flames we see
Generation of flames -
volatile compounds
eagerly reacting withoxygen

When the temperature of wood is increased (through application of heat), first the water is driven off. This occurs up to about 200°C. Between approximately 200°C–280°C the heat starts to break down the hemicellulose compounds into Carbon Monoxide, Carbon Dioxide, Acetic Acid, (and more water vapour); these are driven out. Between 280°–500° decomposition of the longer cellulose and lignin begins and produces light tars and Methyl Alcohol
Burning process:
< 200°C
- water is driven off200°C-280°C
- heat breaks down the hemicellulose compounds into Carbon Monoxide, Carbon Dioxide, Acetic Acid, and more water vapour> 280°C
- hydrogen is still produced. Oxygen reacts directly with the Carbon left in the wood exothermically (process happening in the glowing embers)
-
A couple of hundred intermediate products (organic acids, ketones, esters, aldehydes …) have been identified as being produced by the pyrolysis of wood
Output from wood pyrolysis
-
The pyrolysis of wood is an incredibly intricate and complex process that is not completely mapped out and the exact output depends of many variables
Pyrolysis is complex and relies on lots of variables (type of wood, temperature...)
-
The correct term to describe what is going on when we ‘burn’ wood is Pyrolysis
Pyrolysis (from Greek) - correct term for "burning" wood (thermal decomposition)
-
The chemical composition of wood varies from species to species, but is approximately 50% carbon, 42% Oxygen, 6% Hydrogen, 1% Nitrogen, and 1% other elements (mainly Calcium, Potassium, Sodium, Magnesium, Iron, and Manganese) by weight
Chemical composition of wood. Mainly:
- 50% carbon
- 42% oxygen
- 6% hydrogen
-
Wood is the hard-fibrous material that comes from the trunk, stems, roots, and branches of a once living tree

He expects that the logging project near Quimby’s land will likely generate about $755,250 at the state’s average sale price, $50.35 per cord of wood. The land has about 1,500 harvestable acres that contain about 30 cords of wood per acre, or 45,000 cords, but only about a third of that will be cut because the land is environmentally sensitive, Denico said. The Bureau of Parks and Lands expects to generate about $6.6 million in revenue this year selling about 130,000 cords of wood from its lots, Denico said. Last year, the bureau generated about $7 million harvesting about 139,000 cords of wood. The Legislature allows the cutting of about 160,000 cords of wood on state land annually, although the LePage administration has sought to increase that amount.
