Wool is the fibre derived from the hair of animals of the Caprinae family, principally sheep and goats, but the hair of other mammals such as alpacas may also be called wool. This article deals with the wool produced from domestic sheep. Wool is the fibre produced as the outer coat of sheep. Most of the fibre from domestic sheep has two qualities that distinguish it from hair or fur: it has scales which overlap like shingles on a roof and it is crimped; in some fleeces the wo ...

Air pollution is a broad term applied to all physical (particulate matter), chemical, and biological agents that modify the natural characteristics of the atmosphere. Some definitions also consider physical perturbations such as noise pollution, heat, radiation or light pollution as air pollution.[citation needed] Definitions commonly include the term harmful as a requisite ...

An apartment (or flat in Britain and other Commonwealth countries) is a self-contained housing unit that occupies only part of a building. Apartments may be owned (by an owner-occupier) or rented (by tenants). Some apartment-dwellers own their apartments, either as co-ops, in which the residents own shares of a corporation that owns the building or development; or in condominiums, whose residents own their apartments and share ownership of the public spaces. Most apartments are in buildings designed for the ...

A vacuum cleaner is a device that uses an air pump to create a partial vacuum to suck up dust and dirt, usually from carpeted floors. Most homes with carpeted floors in developed countries possess a domestic vacuum cleaner for cleaning. The dirt is collected by a filtering system or a cyclone for later disposal. Vacuum cleaner - Configurations. Several general configurations for vacuum cleaners have emerged: Upright vacuum cleaners have the pump mounted directly above the suction intake, ...

A bedroom is a room used primarily for sleep, rest or sexual activities. It may or may not contain a bed. In some cultures, dedicated bedrooms form an important part of a home. In others, spaces used primarily for other activities by day become bedrooms at night. Bedroom - Bedrooms in North America and Europe. Many houses in North America and Europe have at least two bedrooms – usually a master bedroom (dedicated to the heads of the household, such as a husband and wife) and one or m ...

Although formaldehyde is a gas at room temperature, it is readily soluble in water, and it is most commonly sold as a 37% solution in water called by trade names such as formalin or formol. In water, formaldehyde polymerizes, and formalin actually contains very little formaldehyde in the form of H2CO monomer. Usually, these solutions contain a few percent methanol to limit the extent of polymerization. Formaldehyde exhibits most of the general chemical properties of the aldehydes, except that is generally more ...

As the raw material has been readily available since the widespread domestication of sheep and similar animals, the use of wool for clothing and other fabrics dates back to some of the earliest civilizations. Prior to invention of shears - probably in the Iron Age - they probably plucked the wool out by hand or by bronze combs. In medieval times, the wool trade was serious business. English wool exports - which bordered on European monopoly - were a significant source of income to the crown. Over the centuries, various British laws co ...

Apartments can be classified into several types. Studio or efficiency apartments tend to be the smallest apartments with the cheapest rents in a given area. These kinds of apartment usually consist mainly of a large room which is the living, dining, and bedroom combined. There are usually kitchen facilities as part of this central room, but the bathroom is its own smaller separate room. Moving up from the efficiencies are one-bedroom apartments where one bedroom is a separate room from the rest of the apartment. Then the ...

Several general configurations for vacuum cleaners have emerged: Upright vacuum cleaners have the pump mounted directly above the suction intake, with the bag mounted on the handle, which rises to about waist height. Upright designs usually employ mechanical beaters, often rotating brushes, to help disturb dust to be vacuumed up; these beaters are usually driven by a belt attached to the vacuum motor. Canister (or cylinder) designs have the motor and bag in a separate canister unit (usual ...

Many houses in North America and Europe have at least two bedrooms – usually a master bedroom (dedicated to the heads of the household, such as a husband and wife) and one or more bedrooms for either the children or guests. In buildings with multiple self-contained housing units (e.g., apartment), the number of bedrooms vary widely. While many such units have at least one bedroom – frequently, these units have at least two – some of these un ...

It is estimated that three million people indirectly die of air pollution each year worldwide. About 90% of these mortalities are largely attributable to indoor air pollution in developing nations. In the U.S. between 50,000 and 100,000 deaths per year are linked to air pollution, more people than die from car accidents. Research published in 2005 suggests that 310,000 Europeans die from air pollution annually. Direct causes of air pollution related deaths include aggravated asthma, bronchitis, emphysema, lung and heart diseases, and other r ...

The first hand-powered cleaner using vacuum principles may have been the "Whirlwind", invented in Chicago in 1865. The first powered cleaner employing a vacuum was patented by H. Cecil Booth, a British engineer, in 1901. He noticed a device used in trains that blew dust off the chairs, and thought it would be much more useful to have one that sucked dust. He tested the idea by laying a handkerchief on the seat of a dinner chair, putting his mouth to it and sucking hard. He nearly choked, but upon seeing the dust and dirt collecte ...

Vacuum cleaners working on the cyclone principle became popular in the 1990s. These were adapted from industrial cyclonic separators by James Dyson in 1985. He launched his cyclone cleaner first in Japan in the 1980s at a cost of about US$1,800 and later the Dyson DC01 upright in the UK in 1995 for £200. It was expected that people would not buy a vacuum cleaner at twice the price of a normal cleaner, but it later became the most popular cleaner in the U.K.. Cyclonic cleaners do not use bags: instead, the dust collects in a detachable, cyli ...

The performance of a vacuum cleaner, when mentioned at all by the manufacturer, can be measured by several parameters: airflow, in cubic feet per minute (CFM or ft³/min) or litres per second (l/s) air speed, in miles per hour (mph) or metres per second (m/s) suction, vacuum, or water lift, in inches of water or pascals (Pa) The suction is the maximum pressure difference that the pump can create. For example, a typical domestic model has a suction of about negative 20 kPa. This means that it can l ...

Industrially, formaldehyde is produced by the catalytic oxidation of methanol. The most commonly used catalysts are silver metal or a mixture of an iron oxide with molybdenum and vanadium. In the more commonly used iron oxide system (Formox process), methanol and oxygen react at 250°C to produce formaldehyde according to the chemical equation 2 CH3OH + O2 → ...

In addition to clothing, wool has been used for carpeting, felt, and upholstery. Wool felt covers piano hammers and it is used to absorb odors and noise in heavy machinery and stereo speakers. Ancient Greeks lined their helmets with felt and Roman legionnaires used breastplates made of wool felt. Shoddy is recycled or remanufactured wool. To make shoddy, existing wool fabric is cut or torn apart and respun. As this process makes the wool fibres shorter, the remanufactured fabric is inferior to the original. The recycled wool ma ...

Global wool production is approximately 1.3 million tonnes per annum of which 60% goes into apparel. Australia, China and New Zealand are leading commercial producers of wool. Most Australian wool comes from the merino breed. Breeds such as Lincoln and Romney produce coarser fibres and wool of these sheep is usually used for making carpets. In the United States, Texas, New Mexico and Colorado also have large commercial sheep flocks and their mainstay is the Rambouillet (or French Merino). There is also a thriving 'home flock' continge ...
