Introduction. Records in PASCAL database contain descriptors in English, French, Spanish, and German. Most records contain multiple descriptors in both English and French. Additional descriptors in Spanish may be present in some records in the area of biology since 1985 and all areas since 1987, and in German for the area of metallurgy since 1980. There is an average of 10 or more descriptors (in each available language) per record.

Searching with the /DE suffix retrieves descriptors in English, French, Spanish, or any language in which descriptors have been assigned in a particular record:

S ROBOT ARM/DE S1 177 ROBOT ARM/DE TYPE S1/DE 1/DE/1 DIALOG(R)File 144:(c) 2000 INIST/CNRS. All rts. reserv. English Descriptors: Robotics; Neural network; Automatic control; Robot dynamics; Cerebellum; Functions; Structure; Learning; Computational cerebellar model; Robot arm; Robot arm control; Cerebellar model articulation controller French Descriptors: Robotique; Reseau neuronal; Commande automatique; Dynamique robot; Cervelet; Fonction; Structure; Apprentissage; Algorithmique modele cerebelleux; Bras robot; Commande bras robot; CMAC Spanish Descriptors: Robotica; Red neuronal; Control automatico; Cerebelo; Estructura; Aprendizaje

Descriptors are indexed by an individual word and by a multiword phrase and may be selected as single words using proximity operators or as the complete phrase. Descriptors may include hyphens, commas, or other punctuation. Retain exact spacing and punctuation when selecting the descriptor as the complete phrase, e.g., SELECT X RAY ABSORPTION/DE. If the descriptor phrase contains a slash (/), a colon (:), or some other character that cannot be selected directly, enclose the entire descriptor in single or double quotation marks, e.g., SELECT "PB-206/PB-204"/DE. Use the proximity operators (W) or (N) to replace all punctuation when selecting descriptors as single words, e.g., S SILICA(W)SUB/DE.

A single-word descriptor may be searched using the /DF suffix to retrieve only that word as the full descriptor. Note the difference in retrieval in the following SELECT statements:

S ROBOT/DE S2 12580 ROBOT/DE S ROBOT/DF S3 3323 ROBOT/DF

Set 2 includes records with the word ROBOT anywhere in the Descriptor field, either as the full descriptor or as part of a phrase. SELECT ROBOT/DE re-trieves descriptors such as ROBOT ARM, INDUSTRIAL ROBOT, and ROBOT LAN-GUAGE, as well as the single-term descriptor ROBOT, whereas SELECT ROBOT/DF retrieves only ROBOT as the full descriptor.

Using the /DE suffix also retrieves terms from the Broad Descriptors field (/BT):

SELECT EUROPE/DE S4 390833 EUROPE/DE TYPE S4/BT,DE 4/BT,DE/1 DIALOG(R)File 144:(c) 2000 INIST/CNRS. All rts. reserv. English Descriptors: Architectural history; Architectural style; Underground architecture; Seaside architecture; Removable architecture; Wood construction; Subway station; Parking; Illustrated description; Belgium French Descriptors: Histoire architecture; Style architectural; Architecture souterraine; Architecture balneaire; Architecture demontable; Construction bois; Station metro; Stationnement; Description illustree; Belgique; SACRIPANTI (Maurizio); WOERNDL (Hans, Peter) Spanish Descriptors: Historia arquitectura; Estilo arquitectural; Arquitectura subterranea; Arquitectura balnearia; Arquitectura desmontable; Construccion madera; Estacion metro; Estacionamiento; Descripcion ilustrada; Belgica Broad Descriptors: Europe; Europe; Europa

Descriptors are also searchable by separate languages.

English Descriptor (/ED). English-language descriptors are searchable separately in the /ED field. English descriptors are indexed both by the individual word and by the complete phrase and are searchable using the /ED suffix, e.g.,

S LASER BEAMS/ED S5 4378 LASER BEAMS/ED TYPE S5/ED 5/ED/1 DIALOG(R)File 144:(c) 2000 INIST/CNRS. All rts. reserv. English Descriptors: Magazine article; Bose-Einstein condensation; Superfluidity; Rubidium; Gases; Vortices; Photon-atom collisions; Laser beams

Assigned descriptors in the /ED field may reflect either British or American spellings. Search strategy should reflect these variations, e.g., SELECT COLOR OR COLOUR/ED.

French Descriptor (/FD). French-language descriptors are searchable separately in the /FD field. When there is a difference in the number of descriptors assigned in each language, French descriptors are the most numerous. French descriptors are indexed both by the individual word and by the complete phrase and are searchable using /FD suffix, e.g.,

S TURBULENCE(W)OPTIQUE/FD S6 19 TURBULENCE(W)OPTIQUE/FD TYPE S6/FD 6/FD/1 DIALOG(R)File 144:(c) 2000 INIST/CNRS. All rts. reserv. French Descriptors: Etude theorique; Equation Schroedinger; Equation non lineaire; Optique non lineaire; Propagation onde electromagnetique; Air; Faisceau laser; Faisceau pulse; Domaine temps fs; Generation plasma; Filamentation; Turbulence optique; Distance propagation; 5250J; 4265J

Spanish Descriptor (/SD). Spanish-language descriptors are searchable separately in the /SD field. Spanish descriptors are indexed both by the individual word and by the complete phrase and are searchable using the /SD suffix, e.g.,

S ESPECTRO(N)POTENCIA/SD S7 2363 ESPECTRO(N)POTENCIA/SD TYPE S7/SD 7/SD/1 DIALOG(R)File 144:(c) 2000 INIST/CNRS. All rts. reserv. Spanish Descriptors: Sueno paradojal; Encefalo; Electroencefalografia; Analisis espectral; Espectro potencia; Ritmo gamma; Ritmo beta ; Campo magnetico; Alta frecuencia; Analisis temporal; Serie temporal; Hombre; Correlacion cruzada

Other Language Descriptor (/OD). Descriptors in languages other than French, English, and Spanish are searchable separately in the /OD field. Only German-language descriptors for the area of metallurgy appear in the Other Language Descriptor field. Other language descriptors are indexed both by the individual word and by the complete phrase and are searchable using the /OD suffix, e.g.,

S EXPERIMENTELLE UNTERSUCHUNG/OD S8 345202 EXPERIMENTELLE UNTERSUCHUNG/OD TYPE S8/OD 8/OD/1 DIALOG(R)File 144:(c) 2000 INIST/CNRS. All rts. reserv. Other Descriptors: Impfen; Fluessige Legierung; Kornfeinen; Giessen; Mathematisches Modell; Korngroesse; Titanlegierung; Experimentelle Untersuchung

Alloys and composites. The composition of alloys and notes on other composites are searchable with the /DE or /FD suffix, but are not included in the other language-specific descriptor fields (/ED, /SD, or /OD). Expressions describing an alloy and its composition often include symbols that cannot be selected directly. Search such a phrase by en-closing the entire phrase in single or double quotation marks, e.g.,

S "ALLIAGEM NI:>50"?/FD S9 2210 "ALLIAGEM NI:>50"?/FD TYPE S9/DE 9/DE/1 DIALOG(R)File 144:(c) 2000 INIST/CNRS. All rts. reserv. English Descriptors: Fatigue; Temperature effect; Crack propagation; Fatigue crack; Superalloy; Cyclic load; Nickel alloy; High temperature; Scanning electron microscopy; In situ; Propagation velocity; Mechanical properties; Nickel Aluminium Cobalt Chromium Molybdenum Titanium Alloys French Descriptors: Fatigue; Effet temperature; Propagation fissure; Fissure fatigue; Superalliage; Charge cyclique; Nickel alliage; Haute temperature; Microscopie electronique balayage; In situ; Vitesse propagation; Propriete mecanique; Nickel Aluminium Cobalt Chrome Molybdene Titane Alliage; AlliageM Ni:>50 Al:1-1.5 Co:10-15 Cr:15-20 Mo:3-5 Ti:3-5; Waspaloy Spanish Descriptors: Fatiga; Efecto temperatura; Propagacion fisura; Fisura fatiga; Superaleacion; Carga ciclica; Niquel aleacion; Alta temperatura; Microscopia electronica barrido; In situ; Velocidad propagacion; Propiedad mecanica; Niquel Aluminio Cobalto Cromo Molibdeno Titanio Aleacion

Note that if a phrase enclosed in quotation marks is truncated, the truncation symbol must follow the closing quotation mark.

When using proximity operators, use the (W) operator to replace all punctuation, e.g., SELECT ALLIAGEM(W)NI(W)50/FD.
