Main article: lead poisoning The concern about lead's role in mental retardation in children has brought about widespread reduction in its use (lead exposure has been linked to schizophrenia). Paint containing lead has been withdrawn from sale in industralised countries, though many older houses may still contain substantial lead in their old paint: it is generally recommended that old paint should not be stripped by san ...

Babies and some types of domestic birds, such as lovebirds and budgerigars can often be entertained for extended periods by being shown their reflection in the two different sides of a metal spoon. Many people also derive amusement from the practice of hanging a spoon from one's nose which can be accomplished by breathing on the curved area and then carefully placing it on the tip of your nose. This would however be considered poor table manners. ...

Ceramic - Mechanical properties. Ceramic materials are usually ionic or covalently-bonded materials, and can be crystalline or amorphous. A material held together by either type of bond will tend to fracture before any plastic deformation takes place, which results in poor toughness in these materials. Additionally, because these materials tend to be porous, the pores and other microscopic imperfections act as stress concentrators, decreasing the toughness further, and reducing the tensile strength. These combine to give catastrophic failures, as opposed to the ...

The PCB will then enter the fluxing zone, which applies flux to the underside of the board. Two types of fluxers are used: the spray fluxer and foam fluxer. Wave soldering - Spray fluxer. The spray fluxer consists of a robotic arm which travels from side to side while spraying a fine mist of flux onto the bottom side of the board. Some systems will then use compressed air to remove excess flux or to completely remove flux from some areas. See also:

Testament was formed in the San Francisco area in 1983 by guitarist Eric Peterson and his friend, Derrick Ramirez, also a guitarist, originally using the name Legacy. The band soon recruited bassist Greg Christian, drummer Louie Clemente, and vocalist Steve Souza. Ramirez was subsequently replaced by young guitar prodigy Alex Skolnick, who had studied under the legendary bay-area guitarist Joe Satriani. Steve Souza subsequently left the band, and suggested that Chuck Billy should replace him on lead vocals. While recording their first album, the band was forced to change their name to Testament because another ban ...

Early axial compressors offered poor efficiency, so poor that in the early 1920s a number of papers claimed that a practical jet engine would be impossible to construct. Things changed dramatically after A. A. Griffith published a seminal paper in 1926, noting that the reason for the poor performance was that existing compressors used flat blades and were essentially "flying stalled". He showed that the use of airfoils instead of the flat blades would dramatically increase efficiency, to the point where a practical jet engine was a real possibility. He concluded the paper with a basic diagram of such an engine, which included a se ...

Agricultural settlements had until this time been almost completely dependent on stone tools. In Eurasia, copper and bronze tools, decorations, and weapons began to become commonplace around 3000 BCE. After bronze, the Eastern Mediterranean region, Middle East and China saw the introduction of iron tools and weapons. The Americas may not have had metal tools until the Chavin horizon in 900 BCE. We also know that the Moche had metal armor, knives and tableware. Even the metal-poor Inca had metal-tipped plows, at least after the conquest of Ch ...

Gottlieb Daimler made his first mechanical-engineering activities in an industry at Graffenstaden. Which abandoned soon (1857) to begin serious studies of his vocation in the Polytechnic school of Stuttgart (continuing the Corps Stauffia.) After his graduation he acquired experience traveling through diverse European countries. In France he contacted the new gas engine of J J Lenoir; and worked in some factories: one of locomotives (Strasbourg) and other band-saw one. In United Kingdom, Daimler developed engineering works at Oldham, L ...

A step bit, step drill, or Unibit is a roughly conical bit with a stair-step profile. They are used for drilling in sheet metal up to the thickness of one of the steps. Due to their design, a single bit can be used for drilling a wide range of hole sizes. Some bits come to a point and are thus self-starting. The larger-size bits have blunt tips and are used for hole enlarging. They are now available in fractional inch and metric sizes. An additional use of step bits is deburring holes left by other bits, as the sh ...

Fuller's young daughter died from an infection contracted because they lived in poor housing during a Chicago winter. This horrid experience permanently changed Fuller's priorities. The first, most successful Dymaxion house design was for the U.S.S.R. for temporary housing during World War II. It was mass-produced and based on tooling for a sheet-metal grain silo. Several hundred units were constructed and installed, but before the war ended and the state housing ministry decided that the housing was unsuitable for permanent use. The grain-s ...

Lo-fi music is a musical genre which uses lo-fi recording practices. The aim is to sound authentic, rather than over-produced. Many lo-fi artists use inexpensive cassette tape recorders for their music. Lo-fi music arguably dates back to the Beatles or Buddy Holly (Holly recorded some songs in a converted garage). As a genre, lo-fi is mainly associated with recordings from the 1980s onwards, when cassette technology such as Tascam's four-track Portastudio became widely available. Prime early exponents included Daniel Johnston, ...

Live action cut scenes have many similarities to films. For example, the cut scenes in Wing Commander IV utilised both fully constructed sets, and "name" actors such as Mark Hamill and Malcolm McDowell for the portrayal of characters. Recently, some movie tie-in games, such as Electronic Arts' Lord of the Rings games, have also extensively used film footage and other assets from the film production in their cut scenes. Another movie tie-in, Enter the Matrix, used film footage shot concurrently with The Matrix Reloaded that was also dire ...

His scheme of composition is grand and decorous; his chiaroscuro excellent, and especially his perspectives, which he would design on a very elaborate scale by the eye alone; his color is more open to criticism, but this remark applies much less to the frescoes than the tempera-pictures, which are sometimes too broadly and crudely bright. He worked in these two methods alone never in oils; and his frescoes are what t ...

Born in Honolulu, Hawaii, Cayetano was estranged from his mother at a young age. Cayetano was raised by his father in Kalihi, an ethnic Filipino neighborhood west of Downtown Honolulu. He would grow up as a latchkey child. In Kalihi, he attended Wallace Rider Farrington High School, a public school aptly known locally as "Home of the Governors" as its buildings were named after several early Hawaii statesmen. The school was only a few blocks from his home. Cayetano received poor grades throughout his years at Farrington and was often disciplined by his teachers and counselors. He b ...

The traditional view of historians, informed by the work of Michael Rostovtzeff, was of a widespread economic decline at this time. However, consistent archaeological evidence has told another story, and the accepted view is undergoing re-evaluation. The destruction of many sites is now believed to be much later than had formerly been thought. Many buildings changed use, but were not destroyed. There were growing barbarian attacks, but focused on vulnerable rural settlements rather than the towns. Some villas such as Great Casterton in Rutla ...

Iron ores are overwhelmingly derived from ancient sediments known as banded iron formations (BIFs). These sediments are composed of iron oxide minerals deposited on the sea floor. Particular environmental conditions are needed to transport enough iron in sea water to form these deposits, such as acidic and oxygen-poor atmospheres within the Proterozoic Era. Often, more recent weathering during the Tertiary or Eocene is required to convert the usual magnetite minerals into more easily processed hematite. Some iron deposits withi ...

Lattimer massacre - Slavic immigration. The agricultural economy of Eastern Europe was in difficulty in the late 19th century. Most families farmed small plots of land, sometimes no bigger than today's suburban backyards. These conditions produced a mass exodus to the United States at a time when that region was experiencing rapid industrialization and an explosion in steel production. Many of these new immigrants mined the coal needed to fuel this burgeoning industry. < ...

The result of hair metal's decline was the grunge explosion in the early 1990s. By 1992 (1992 in music), hair metal bands were massively unpopular as grunge groups like Nirvana (Nevermind), Pearl Jam (Ten) and Alice in Chains (Dirt) dominated the charts. Their success lasted only a few years, however, as bands found it difficult to maintain their "alternative" sound after going mainstream. In addition, former N.W.A. member Dr. Dre (The Chronic) brought gangsta rap to pop audiences. By the mid-90s, alternati ...

Megadeth - The Early Years. Shortly after lead guitarist Dave Mustaine was fired from Metallica due to alcohol problems and personality conflicts, Mustaine and bassist David Ellefson formed Megadeth. As Mustaine himself says, "I could only focus on one thing [after being kicked out of Metallica]: I wanted blood... theirs." After searching for a vocalist and not finding what he wanted, Mustaine became the band's singer and primary lyricist as well as the main songwriter and rhythm guitarist. The band soon added ja ...
