In chemical terms, the difference between hardwood and softwood is reflected in the composition of the constituent lignin. Hardwood lignin is primarily derived from sinapyl alcohol and coniferyl alcohol. Softwood lignin is mainly derived from coniferyl alcohol.
Which wood has lignin that comes primarily from one type of alcohol?
Softwood

Swaziland derives its name from a later king named Mswati II. KaNgwane, named for Ngwane III, is an alternative name for Swaziland the surname of whose royal house remains Nkhosi Dlamini. Nkhosi literally means "king". Mswati II was the greatest of the fighting kings of Swaziland, and he greatly extended the area of the country to twice its current size. The Emakhandzambili clans were initially incorporated into the kingdom with wide autonomy, often including grants of special ritual and political status. The extent of their autonomy however was drastically curtailed by Mswati, who attacked and subdued some of them in the 1850s.
What is the literal translation of Nkhosi?
king

Agriculture and horticulture seek to optimize the capture of solar energy in order to optimize the productivity of plants. Techniques such as timed planting cycles, tailored row orientation, staggered heights between rows and the mixing of plant varieties can improve crop yields. While sunlight is generally considered a plentiful resource, the exceptions highlight the importance of solar energy to agriculture. During the short growing seasons of the Little Ice Age, French and English farmers employed fruit walls to maximize the collection of solar energy. These walls acted as thermal masses and accelerated ripening by keeping plants warm. Early fruit walls were built perpendicular to the ground and facing south, but over time, sloping walls were developed to make better use of sunlight. In 1699, Nicolas Fatio de Duillier even suggested using a tracking mechanism which could pivot to follow the Sun. Applications of solar energy in agriculture aside from growing crops include pumping water, drying crops, brooding chicks and drying chicken manure. More recently the technology has been embraced by vinters, who use the energy generated by solar panels to power grape presses.
During the Little Ice Age, what did English and French farmers use to increase collection of solar energy?
fruit walls
