Low insertion force sockets LIF are integrated circuit sockets that are designed so the force required to insert or remove a package is low. Initially, the LIF connectors were designed as a cheaper alternative compared to Zero insertion force ZIF connectors, to facilitate programming and testing of equipment. Compared with standard IC sockets, they have a lower friction force between the contacts of the device and the socket, making insertion and removal of the device easier, while at the same time eliminating the need for the complex mechanism that is used in ZIF sockets. The disadvantages of LIF connectors are that the grip force between the contacts is lower, and the contacts can oxidize faster and decrease the lifespan of the connector. With the advent of frequent changes in PC processors, a need arose for these systems. Intel introduced the LIF socket system, in which the processor is inserted into the socket, rather than fixed by a lever. This type of socket was used for some types of 386s and early 486s. This type of socket has been replaced by the zero insertion force ZIF socket, although LIF sockets are now used in modern 1.8 hard disks.

Orphan date February 2009 In the field of engineering mechanics , a zeroforce member refers to a member a single truss segment in a truss which, given a specific structural load load , is at rest neither in tension mechanics tension , nor in compression physical compression . In a truss a zeroforce member is often found at pins any connections within the truss where no external load is applied and three or fewer truss members meet. Recognizing basic zeroforce members can be accomplished by analyzing the force s acting on an individual pin in a physical system . NOTE If the pin has an external force or Moment physics moment applied to it, then all of the members attached to that pin are not zeroforce members UNLESS the external force acts in a manner that fulfills one of the rules below If only two members meet in an unloaded Joint building joint , both are zeroforce members. If three members meet in an unloaded joint of which two are in a direct line with one another, then the third perpendicular member is a zeroforce member. If two members meet in a loaded joint and the line of action of the load coincides with one of the members, the other member is a zeroforce member.

An insertion sequence also known as an IS , an insertion sequence element , or an IS element is a short DNA sequence that acts as a simple transposon transposable element . Insertion sequences have two major characteristics they are small relative to other transposable elements generally around 700 to 2500 base pair bp in length and only code for proteins implicated in the transposition activity they are thus different from other transposons , which also carry accessory genes such as antibiotic resistance genes . These proteins are usually the transposase which catalyses the enzymatic reaction allowing the IS to move, and also one regulatory protein which either stimulates or inhibits the transposition activity. The coding region in an insertion sequence is usually flanked by inverted repeat s. For example, the well known IS 911 1250 bp is flanked by two 36bp inverted repeat extremities and the coding region has two genes partially overlapping orfA and orfAB , coding the transposase OrfAB and a regulatory protein OrfA . http www is.biotoul.fr is IS infos IS3 family.html IS911 A particular insertion sequence may be named according to the form IS n , where n is a natural number number ....

Unreferenced stub date December 2009 Orbit insertion is a deceleration or acceleration manoeuvre performed by a spacecraft designed to allow the spacecraft to be captured into orbit around a planet or other body such as a natural satellite moon . From a trans planetary perspective, the spacecraft approaches a body at a speed greater than the escape velocity of that body. The spacecraft must reduce its speed to below the body s escape velocity. This is usually accomplished through a Retrorocket rocket firing orbit insertion burn . The reduction in speed allows the spacecraft to settle into orbit around the body. Aerobraking can also be used to slow the spacecraft, assuming the body in question has an atmosphere. From a launch perspective, orbit insertion is also the manoeuvre used by spacecraft to establish an orbit around a body. Many flight profiles involve establishing a base orbit in space during the launch phase and performing refining manoeuvres to insert the craft into the desired orbit. The difference here is that the vehicle usually must make minor course corrections and possibly even accelerate to attain desired orbit around a body as opposed to decelerating from a trans planetary trajectory.

This is one of the three main requirements in a nuclear weapon design to create a working fission atomic bomb . The need for a short insertion time with plutonium is the reason why the implosion method was chosen for the first plutonium bomb, while with uranium 235 it is possible to use a gun design. The basic requirements are To start with a subcritical system To create a super prompt critical system To make the change between these two states in a length of time insertion time which is shorter than the time between the random appearance of a neutron in the fissile material through spontaneous fission or by other random processes. Also at the right moment in time, neutrons must be injected into the fissile material to start up the fission process. This can be done by several methods. Alpha emitters such as polonium or plutonium 238 can be rapidly combined with beryllium to create a neutron source.

Nofootnotes date January 2009 An insertion device is a part of a synchrotron which produces highly brilliant, forward directed and quasi monochromatic synchrotron radiation . The name comes from the fact that these are devices which are inserted into a straight section of a synchrotron or a storage ring . They are not essential to the operation of the storage ring itself, their only function is to generate synchrotron radiation. Insertion devices typically consist of arrays of magnets which are used to generate a spatially periodic magnetic field at the electron beam path. The magnetic fields cause transverse acceleration to the relativistic electron s, causing them to emit synchrotron radiation. There are two types of insertion devices in wide usage at List of synchrotron radiation facilities synchrotron radiation facilities . In a wiggler synchrotron wiggler the period and the strength of the magnetic field is not tuned to the frequency of radiation produced by the electrons. Thus every electron in the electron bunch radiates independently, and the resulting radiation spectrum is broad. A wiggler can be considered to be series of bending magnet s concatenated together, and its radiation intensity scales as the number of magnetic poles in the wiggler. In an undulator source the radiation produced by the oscillating electrons interferes constructively with the motion of other electrons, causing the radiation spectrum to have a relatively narrow bandwidth. The intensity of radiation scales as math N 2 math , where math N math is the number of poles in the magnet array. Undulators are the brightest sources of X ray s and extreme ultraviolet radiation mankind has yet invented. Insertion devices are also the radiation producing element in free electron laser s.

Repeater insertion is a technique for reducing the time delay associated with long wire lines in integrated circuits. The technique involves cutting the long wire into one or more short wires and inserting a repeater between each new pair of short wires. The time it takes for a signal to travel from one end of a wire to the other end is known as wire line delay or just delay. In an integrated circuit, this delay is characterized by RC circuit RC , the Electrical resistance resistance of the wire R multiplied by the wire s capacitance C . Thus, if the wire s resistance is 100 ohm s and its capacitance is 0.01 Farad microfarad F , the wire s delay is one microsecond s . To first order, the resistance of a wire on an integrated circuit is directly proportional , or linear , according to the wire s length. If a 1 mm length of the wire has 100 ohms resistance, then a 2 mm length will have 200 ohms resistance. For the purposes of our highly simplified discussion, the capacitance of a wire also increases linearly along its length. If a 1 mm length of the wire has 0.01 F capacitance, a 2 mm length of the wire will have 0.02 F, a 3 mm wire will have 0.03 F, and so on. Thus, the time delay through a wire increases with the square of the wire s length. This is true, to first order, for any wire whose cross section remains constant along the length of the wire. border 1 style text align center wire length resistance R capacitance C time delay t 1 mm 100 ohm 0.01 F 1 s 2 mm 200 ohm 0.04 F 4 s 3 mm 300 ohm 0.09 F 9 s wire resistance capacitance time delay length R C t 1 mm 100 ohm 0.01 F 1 s 2 mm 200 ohm 0.02 F 4 s 3 mm 300 ohm 0.03 F 9 s The interesting consequence of this behavior ... by cutting it in half and inserting a repeater is known as repeater insertion .
