Conifers Of Mexico
Mexican conifers extend mainly across the main mountain ranges Sierra Madre Oriental, Sierra Madre Occidental and the Trans-Mexican Volcanic Belt. Enclosed between these mountains there are dispersed groups of conifers in mid and high elevations valleys when rainfall conditions allow their growth. Mexican conifers grow in some places often associated with oaks. The dry season is about 7–8 months. Most rainfall (80-95%) occurs from June to October (5 months) and for only four months in the north. Precipitation throughout the year is present only in a little portion of the Sierra Madre Oriental in the State of Veracruz. The greatest number of species belong to the ''Pinus'' genus, including about 60 species and subspecies. Mexican conifers growing in subtropical climates include Pinus chiapensis, Pinus oocarpa, and Pinus tecunumanii. Mexican conifers in temperate-to-cool climates are as follow: * Pinus ayacahuite * Pinus cembroides * Pinus durangensis * Apache pine, Pinus engelman ...

Sierra Madre Oriental
The Sierra Madre Oriental () is a mountain range in northeastern Mexico. The Sierra Madre Oriental is part of the American Cordillera, a chain of mountain ranges (cordillera) that consists of an almost continuous sequence of mountain ranges that form the western "backbone" of North America, Central America, South America, and Antarctica. Setting Spanning the Sierra Madre Oriental runs from the Rio Grande on the border between Coahuila and Texas south through Nuevo León, southwest Tamaulipas, San Luis Potosí, Querétaro, and Hidalgo to northern Puebla, where it joins with the east-west running Eje Volcánico Transversal of central Mexico. The northernmost are the Sierra del Burro and the Sierra del Carmen which reach the border with the United States at the Rio Grande. North of the Rio Grande, the range continues northwestward into Texas and beyond as the Davis and Guadalupe Ranges. Mexico's Gulf Coastal Plain lies to the east of the range, between the mountains and the Gul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Resin
In polymer chemistry and materials science, resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses on naturally occurring resins. Plants secrete resins for their protective benefits in response to injury. The resin protects the plant from insects and pathogens. Resins confound a wide range of herbivores, insects, and pathogens, while the volatile phenolic compounds may attract benefactors such as parasitoids or predators of the herbivores that attack the plant. Composition Most plant resins are composed of terpenes. Specific components are alpha-pinene, beta-pinene, delta-3 carene, and sabinene, the monocyclic terpenes limonene and terpinolene, and smaller amounts of the tricyclic sesquiterpenes, longifolene, caryophyllene, and delta-cadinene. Some resins also contain a high proportion of resin acids. Rosins on the other hand are less ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paper
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year. It is a versatile material with many uses, including printing, painting, graphics, signage, design, packaging, decorating, writing, and cleaning. It may also be used as filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, or currency and security paper, or in a number of industrial and construction processes. The papermaking process developed in east Asia, probably China, at least as early as 105 CE, by the Han court eunuch Cai Lun, although the ...

Rustic Furniture
Rustic furniture is furniture employing sticks, twigs or logs for a natural look. The term “rustic” is derived from Latin “rusticus” (peasant; as opposed to urban). The style is rooted in Romantic tradition. In the US it is almost synonymous with the National Park Service rustic style of architecture. Many companies, artists and craftspeople make rustic furniture in a variety of styles and with a variety of historical and contemporary influences. History The rustic furniture movement developed during the mid- to late-1800s. John Gloag in “A Short Dictionary Of Furniture” says that “chairs and seats, with the framework carved to resemble the branches of trees, were made in the middle years of the 18th century, and there was a popular fashion for this naturalistic rustic furniture” in England. Sue Howard Stephenson explains in her “Rustic Furniture” (1979) that the movement was actually a revival of European styles introduced during the Romantic movement and a ...
