Alphanumeric codes

A card may be a typical card or another type of device, such as a key fob or wand. These cards store electronic information, which can range from a simple code (i.e., the alphanumeric code on a Proximity card) to individualized personal data (i.e., biometric data on a Smartcard). The card reader reads the information stored on the card and sends it to the control unit, which determines the appropriate action to take when a card is presented. For example, in a card access system, the control unit compares the information on the card to stored access authorization information to determine if the card holder is authorized to proceed through the door. If the information stored in the card reader system indicates that the key is authorized to allow entrance through the doorway, the system disengages the lock and the key holder can proceed through the door. 

Records are retained for an appropriate length of time (generally 10 years or two generations over treatment duration) in machine-readable form. This is perhaps the most technologically controversial provision. While it is theoretically possible to retain machine-readable records (ASCII, e.g.—the alphanumeric code—is several decades old), the hkelihood that a formatted electronic document will be physically readable several years later is remote. Consider, for example, the 514-in. floppy disks of 10 years ago and the fact that new sizes of CDs are currently being introduced. 

A minor change in an existing code imprint for a dosage form. For example, changing from a numeric to alphanumeric code. 

The chemical history of the particles is recorded (e.g., each T-bag is labeled by an alphanumeric code). 

An indexing or numbering system allows for ease in referencing and locating the SOP for current use, and it assists in pinpointing specific SOPs that were in effect for past studies. A unique number or alphanumeric code for each SOP can meet these needs. 

Personal Identification Number A PIN is an alphanumeric code or password used to authenticate the identity of an individual. 

Once the sampling grid has been defined, each cell should be labelled with an alphanumeric code later used to identify correspondent samples collected in the... 

Include the established (generic) and proprietary (trade) name(s), synonyms (e.g., different names being used for the same drug in other countries), CAS registry number, and code number(s). Most drugs early in their investigation are referred to by some alphanumeric code number until a generic name has been officially approved by the USAN and/or by the WHO as an INN. 

These are the power tools of the spreadsheet because they do the calculations. A cell can be referred to by its alphanumeric code, e.g. A5 (column A, row 5) and the value contained in that cell manipulated within a formula, e.g. (A5 + 10) or (A5 + B22) in another cell. Formulae can include a diverse array of pre-programmed functions which can refer to a cell, so that if the value of that cell is changed, so is the result of the formula calculation. They may also include limited branching options through the use of logical operators. 

In this edition, the world of minerals is divided by chemical features into ten classes, each of which is subdivided, on chemical-structural principles, into divisions, subdivisions, groups of isotypic and homeotypic minerals, or individual minerals with unique structure types groups with two or more mineral names comprise minerals with similar structure or composition. The classification system and alphanumeric coding scheme used in this 9 edition of the Strunz Mineralogical Tables were presented at the 1994 IMA meeting in Pisa. They permit the insertion of thousands of new minerals in the future without changing the basic classification framework. 

It is hoped that the small number of classes, the logical classification principles, the specific rendition of chemical formulae, and the alphanumeric coding scheme make it relatively easy for scientists and friends of mineralogy to keep the entire system in mind. 

The most general method of encoding a chemical library is based on a small device which, upon activation, emits a given radiofrequency (rf). This device needs to be attached to the synthetic platform (beads, resins, tubes, etc.) on/in which the synthesis of products takes place. The device (which is 8 mm x 1 mm in size) contains three components first, a memory for alphanumeric codes second, a rectifying circuit which absorbs radiofrequency energy and converts this energy into electrical energy. The latter is used by the third component, an antenna, to transmit the code to an external receiver that is linked to a computer. 

PDB-ID Codes. The structure record accessioning scheme of the Protein Data Bank is a unique four-character alphanumeric code, called a PDB-ID or PDB code. This scheme uses the digits 0 to 9 and the uppercase letters A to Z. This allows for over 1.3 million possible combinations and entries. Many older records have mnemonic names that make the structures easier to remember, such as 3INS, the record for insulin shown earlier. A different method is now being used to assign PDB-IDs, with the use of mnemonics apparently being abandoned. 

The laboratory must have a system to uniquely identify the samples and associate each sample with the collection document or other external chain of custody link. Typically, a unique numeric, or alphanumeric code will be assigned to... 

A coding system uses a few digits or alphanumeric codes to represent a group (family) of similar parts. The classification system is embedded into the coding system. For example, one can easily see that parts can be classified as rotational and nonrotational. A crude coding system can have 0 ... 

The selected alphanumeric code is closely related to the requirement s position in the hierarchic structure and enables more organized and easier woik with the requirements.

Chemical History of the Resin Formulations. The most straightforward solution to track the chemical history during split-and-pool synthesis is labeling paper disks," T-bags, wafers, or capsules with an alphanumeric code... 

There was a consensus that there is a need for a unique identifier a simple alphanumeric code based on the transformation event (rather than other options such as a new variety), with a single digit for verification. The unique identifier should be a key to unlocking more detailed information in the product database and interoperable systems (for example, the Biosafety Clearing-House). As such, it should be kept short, simple and user friendly. It should also be built in a flexible way and might potentially serve as a core unique identifier for future developments. It should also take into account experience with, and be applicable to, existing products. 

The unique identifier should include one verification digit, which shall be separated from the rest of the unique identifier digits by a dash. The verification digit is intended to reduce errors by ensuring the integrity of the alphanumeric code, entered by the users of the database. 

RC contains the alphanumeric code assigned to the approximately 33,000 compounds appearing on the EPA TSCA Inventory Candidate List of Chemical Substances. This code should be reported to EPA, along with the CAS Registry Number, to satisfy TSCA reporting requirements.
