Brain death is defined as a complete and irreversible cessation of brain activity. Absence of apparent brain function is not enough. Evidence of irreversibility is also required. Brain-death is often confused with the state of vegetation. Traditionally, death has been defined as the cessation of all body functions, including respiration and heartbeat. Since it became possible to revive some people after a period without respiration, heartbeat, or other visible signs of life, as well as to maintain respiration and blood f ...

A dye can generally be described as a colored substance that has an affinity to the substrate to which it is being applied. The dye is usually used as an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber. In contrast, a pigment generally has no affinity for the substrate, and is insoluble. Archaeological evidence shows that, particularly in India and the Middle East, dyeing has been carried out for over 5000 years. The dyes were obtained from either animal, vegetable or mineral origin, ...

The Chihuahuan Desert is a desert that straddles the U.S.-Mexico border. On the U.S. side it occupies the valleys and basins of central and southern New Mexico and Texas west of the Pecos River; south of the border, it covers the northern half of the Mexican state of Chihuahua and most of Coahuila. The terrain mostly consists of basins broken by numerous small mountain ranges. Several larger mountain ranges include the Sierra Madre, the Sierra del Carmen, the Sacramento Mountains, the Sandia-Manzano Mountains, the Magdal ...

Yellow grease is a term from the rendering industry. It usually means used frying oils from deep fryers and restaurants' grease traps. It can also refer to lower-quality grades of tallow from rendering plants. Yellow grease is recovered, traded as a marginally valuable commodity, and has traditionally been used to spray on roads as dust control, or as animal feed additive. But waste restaurant grease has recently become more desirable as one source of biodiesel fuel for cars. Although most biodiesel is developed from renewable ...

A primary characteristic of vegetation is its three-dimensional structure, sometimes referred to as its physiognomy, or architecture. Most people have an understanding of this idea through their familiarity with terms like "jungle", "woods", "prairie" or "meadow"; these terms conjure up a mental image of what such vegetation looks like. So, meadows are grassy and open, tropical rainforests are dense, tall, and dark, savannahs ...

Much of the work on vegetation classification comes from European and North American ecologists, and they have fundamentally different approaches. In North America, vegetation types are based on a combination of the following criteria: climate pattern, plant habit, phenology and/or growth form, and dominant species. In the current US standard (adopted by the Federal Geographic Data Committee (FGDC), and originally developed by UNESCO and The Nature Conservancy), the classification is hierarchical and incorporates the non-floristic criteria i ...

Vegetation scientists study the causes of the patterns and processes observed in vegetation at various scales of space and time. Of particular interest and importance are questions of the relative roles of climate, soil, topography, and history on vegetation characteristics, including both species composition and structure. Such questions are often large scale, and so cannot be addressed by experimentation in a meaningful way. Observational studies supplemented by knowledge of botany, paleobotany, ecology, soil science etc, are thus the rule in vegetation science. ...

A rhizome is a modified stem serving as an organ of vegetative reproduction. Prostrate aerial stems, called runners or stolons are important vegetative reproduction organs in some species, such as the strawberry, numerous grasses, and some ferns. Adventitious buds develop into above ground stems and leaves, forming on roots near the ground surface and on damaged stems (as on the stumps of cut trees). Adve ...

Leeks were prized by the Ancient Egyptians, Greeks, and Romans, who distributed the vegetable across Europe. The leek is one of the national emblems of Wales, whose citizens wear it on St. David's Day. According to legend, Saint David ordered his Welsh soldiers to identify themselves by wearing the vegetable on their helmets in an ancient battle against the Saxons that took place in a leek field. This story may have been made up by the English poet Michael Drayton but it is known that the leek has been a symbol of Wales for a long tim ...

Leeks are generally considered to have a finer flavor than the common onion. They are an essential ingredient of cock-a-leekie soup and of vichyssoise. They can also be used raw in salads, doing especially well when they are the prime ingredient. Because of their symbolism in Wales (see below) they have come to be used extensively in that country's cuisine. ...

Definition and meaning of Vegetation Regions

Vegetation Regions

Earth is covered with a variety of different associations of vegetation. The kind of vegetation that grows in a region varies with soil, temperature, and precipitation. Although there are numerous subcategories within these big categories, four types of vegetation regions can be identified in Texas and the United States: forest, savanna, grassland, and desert. The single most important factor affecting the distribution of these vegetation types is precipitation.

While olive oil and other pressed oils have been around for millenia, Procter & Gamble researchers were innovators when they started selling cottonseed oil as a creamed shortening, in 1911. Ginning mills were happy to have someone haul away the cotton seeds. P&G researchers learned how to extract the oil, refine it, harden it, and package it as a creamed shortening. Compared to the lard they were already selling to consumers, Crisco was cheaper, easier to stir into a recipe, and could be stored at room temperature for two years. (P&G ...

Vegetable Kingdom In the vegetable stage of the monad's evolution, the faculty of apperception begins to be clearly manifested, which differs from mere perception in that it is accompanied with a certain amount of awareness of results to be achieved.

This is shown in the many ways in which plants can care for themselves, as in sending out rootlets for water or providing for fertilization. In the list of seven creations (cf SD 1:450), the fourth is there called the mukhya or primary because it begins the following system of the four subsequent creations; and the Hindu systems place vegetable bodies in this fourth emanation because they possess individualized lives. All the seven kingdoms or life-waves are manifestations of different groups or life-waves of monads in various degrees of emanational self-manifestation.
