Bead
A bead is a small, decorative object that is formed in a variety of shapes and sizes of a material such as stone, bone, shell, glass, plastic, wood, or pearl and with a small hole for threading or stringing. Beads range in size from under to over in diameter. Beads represent some of the earliest forms of jewellery, with a pair of beads made from ''Nassarius'' sea snail shells dating to approximately 100,000 years ago thought to be the earliest known example. Beadwork is the art or craft of making things with beads. Beads can be woven together with specialized thread, strung onto thread or soft, flexible wire, or adhered to a surface (e.g. fabric, clay). Types of beads Beads can be divided into several types of overlapping categories based on different criteria such as the materials from which they are made, the process used in their manufacturing, the place or period of origin, the patterns on their surface, or their general shape. In some cases, such as millefiori and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bead (woodworking)
A bead is a woodworking decorative treatment applied to various elements of wooden furniture, boxes and other items. A bead is typically a rounded shape cut into a square edge to soften the edge and provide some protection against splitting. Beads can be simple round shapes, or more complex patterns. A bead may be created with an electric router, a special moulding handplane or a scratch stock. Beads are usually cut directly into the edge of the item to which the bead is being applied. However, beads applied across the grain are usually cut into a separate piece which is then fixed in position. A bead is also an important design element in wood turning, a ring-shape or convex curve incised into a piece by the use of a chisel or skew Skew may refer to: In mathematics * Skew lines, neither parallel nor intersecting. * Skew normal distribution, a probability distribution * Skew field or division ring * Skew-Hermitian matrix * Skew lattice * Skew polygon, whose vertices do no ...

Beadwork
Beadwork is the art or craft of attaching beads to one another by stringing them onto a thread or thin wire with a sewing or beading needle or sewing them to cloth. Beads are produced in a diverse range of materials, shapes, and sizes, and vary by the kind of art produced. Most often, beadwork is a form of personal adornment (e.g. jewelry), but it also commonly makes up other artworks. Beadwork techniques are broadly divided into several categories, including loom and off-loom weaving, stringing, bead embroidery, bead crochet, bead knitting, and bead tatting. Ancient beading The art of creating and utilizing beads is ancient, and ostrich shell beads discovered in Africa can be carbon-dated to 10,000 BC. Faience beads, a type of ceramic created by mixing powdered clays, lime, soda, and silica sand with water until a paste forms, then molding it around a stick or straw and firing until hard, were notably used in ancient Egyptian jewelry from the First Dynasty (beginning in t ...

Ferrite Bead
A ferrite bead at the end of a Mini USB cable A ferrite bead (also known as a ferrite block, ferrite core, ferrite ring, EMI filter, or ferrite choke) is a type of choke that suppresses high-frequency electronic noise in electronic circuits. Ferrite beads employ high-frequency current dissipation in a ferrite ceramic to build high-frequency noise suppression devices. Use A ferrite bead with its plastic shell removed Ferrite beads prevent electromagnetic interference (EMI) in two directions: ''from'' a device or ''to'' a device. A conductive cable acts as an antenna – if the device produces radio-frequency energy, this can be ''transmitted'' through the cable, which acts as an unintentional radiator. In this case the bead is required for regulatory compliance, to reduce EMI. Conversely, if there are other sources of EMI, such as household appliances, the bead prevents the cable from acting as an antenna and ''receiving'' interference from these other devices. This is pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anal Beads
Anal beads are a sex toy consisting of multiple balls attached in series. Individual balls are continuously inserted through the anus into the rectum and then removed with varying speeds depending on the desired effect. The main use of anal beads are to help stimulate and or create a orgasm. Design Anal beads are available in many sizes, with individual beads measuring from 25 mm in diameter to 125 mm in diameter or larger. Most users enjoy beads of approximately 45 mm, but those more adventurous or with experience may try larger sizes. Anal beads are commonly made of silicone, plastic, rubber, latex, glass, or metal, and normally end with a ring or similar handle designed for pulling. The purpose of this ring is to prevent the beads from becoming fully lodged in the rectum and to make the toy easier to remove. The beads may either be joined flexibly, requiring individual insertion or by a semi-rigid thin shaft, allowing anal insertion in a single motion. The many ...

Bead Test
The bead test is a traditional part of qualitative inorganic analysis to test for the presence of certain metals. The oldest one is the borax bead test or blister test. It was introduced by Berzelius in 1812.''Materials Handbook: A Concise Desktop Reference'', François Cardarell/ref> Since then other salts were used as fluxing agents, such as sodium carbonate or sodium fluoride. The most important one after borax is microcosmic salt, which is the basis of the microcosmic salt bead test. Borax bead A small loop is made in the end of a platinum wire and heated in a Bunsen burner flame until red hot. A stick made of another inert substance such as a magnesia stick (MgO) may also be used. It is then dipped into powdered borax and held in the hottest part of the flame where it swells up as it loses its water of crystallization and then shrinks, forming a colourless, transparent glass-like bead (a mixture of sodium metaborate and boric anhydride). The bead is allowed to cool and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cell Disruption
Cell disruption is a method or process for releasing biological molecules from inside a cell. Methods The production of biologically interesting molecules using cloning and culturing methods allows the study and manufacture of relevant molecules. Except for excreted molecules, cells producing molecules of interest must be disrupted. This page discusses various methods. Another method of disruption is called cell unroofing. Bead method A common laboratory-scale mechanical method for cell disruption uses glass, ceramic or steel beads, 0.1 to 2 mm in diameter, mixed with a sample suspended in aqueous media. First developed by Tim Hopkins in the late 1970s, the sample and bead mix is subjected to high level agitation by stirring or shaking. Beads collide with the cellular sample, cracking open the cell to release intercellular components. Unlike some other methods, mechanical shear is moderate during homogenization resulting in excellent membrane or subcellular preparations. T ...

Tire Bead
Tire bead is the term for the edge of a tire that sits on the wheel. Wheels for automobiles, bicycles, etc. are made with a small slot or groove into which the tire bead sits. When the tire is properly inflated, the air pressure within the tire keeps the bead in this groove. It is common amongst drivers of off-road vehicles to decrease the air pressure in their tires. This makes the tread of the tire spread out, creating more surface area for the tire's tread to grip the terrain. If the pressure is too low, there may not be enough pressure to keep the bead on the wheel, thus causing the bead to pop off the wheel; this is often referred to as "losing a bead". Beadlocks, which clamp the bead on the wheel, are often used in this case. Often, the bead can become frozen to the rim after rusting occurs, requiring the use of a bead breaker A bead breaker is a tool used for separating tires from rims. The innermost diameter of the tire that interfaces with the rim of a wheel is cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Welding
Welding is a fabrication (metal), fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing Fusion welding, fusion. Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melting, melt the base metal (parent metal). In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that, based on weld configuration (butt, full penetration, fillet, etc.), can be stronger than the base material. Pressure may also be used in conjunction with heat or by itself to produce a weld. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or Oxidation, oxidized. Many different energy sources can be used for welding, including a gas flame (chemical), an electric arc (electrical), a laser, an electron ...

Welding Joint
In metalworking, a welding joint is a point or edge where two or more pieces of metal or plastic are joined together. They are formed by welding two or more workpieces according to a particular geometry. There are five types of joints referred to by the American Welding Society: Butt welding, butt, corner, edge, Lap joint, lap, and tee. These configurations may have various configurations at the joint where actual welding can occur. Butt welds Butt welds are welds where two pieces of metal to be joined are in the same plane. These types of welds require only some kind of preparation and are used with thin sheet metals that can be welded with a single pass. Common issues that can weaken a butt weld are the entrapment of slag, excessive porosity, or cracking. For strong welds, the goal is to use the least amount of welding material possible. Butt welds are prevalent in automated welding processes, such as submerged-arc welding, due to their relative ease of preparation. When met ...
