Magnetic susceptibility of L-amino acids in solid state at high
... Abstract: Magnetic molar susceptibilities (χm) are determined for amino acids in high magnetic fields. The magnetization of the solid state form of L-alanine, L-glutamic acid, L-histidine, L-isoleucine, L-tryptophan, and Ltyrosine were measured at 298 K and 310 K using a commercial SQUID magnetomete ...

... If one chooses a value of R4 = 150 k, g = 980 cm/sec2, and 4mm for z2 – z1, then C1 = 0.15 F. Although this is close to the optimum value, it is usually advisable to make either R4 or C1 adjustable. As the characteristics of the photodiode vary from unit to unit and also since it is difficult to p ...

Magnetic stripe card
A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card. The magnetic stripe, sometimes called swipe card or magstripe, is read by swiping past a magnetic reading head. Magnetic stripe cards are commonly used in credit cards, identity cards, and transportation tickets. They may also contain an RFID tag, a transponder device and/or a microchip mostly used for business premises access control or electronic payment.Magnetic recording on steel tape and wire was invented during World War II for recording audio. In the 1950s, magnetic recording of digital computer data on plastic tape coated with iron oxide was invented. In 1960 IBM used the magnetic tape idea to develop a reliable way of securing magnetic stripes to plastic cards, under a contract with the US government for a security system. A number of International Organization for Standardization standards, ISO/IEC 7810, ISO/IEC 7811, ISO/IEC 7812, ISO/IEC 7813, ISO 8583, and ISO/IEC 4909, now define the physical properties of the card, including size, flexibility, location of the magstripe, magnetic characteristics, and data formats. They also provide the standards for financial cards, including the allocation of card number ranges to different card issuing institutions.
