Management Of Interdependent Data: Specifying Dependency And Consistency Requirements, Amit P. Sheth, Marek Rusinkiewicz Nov 1990

Management Of Interdependent Data: Specifying Dependency And Consistency Requirements, Amit P. Sheth, Marek Rusinkiewicz

Kno.e.sis Publications

Multiple databases that serve the needs of various application systems are considered. One of the significant problems in managing these databases is to maintain the related data items consistent to the required degree. This problem is frequently referred to as `redundant data management'. Since the term `redundancy' tends to imply that the data is unwanted or superfluous, the authors use the more general term `management of interdependent data'. Some preliminary ideas in this area are discussed. The problem of managing interdependent data is characterized, and some important types of interdatabase dependency are identified.


Perforated Prehistoric Ornaments Of Curaçao And Bonaire, Netherlands Antilles, Jay B. Haviser Jan 1990

Perforated Prehistoric Ornaments Of Curaçao And Bonaire, Netherlands Antilles, Jay B. Haviser

BEADS: Journal of the Society of Bead Researchers

This paper describes some of the more distinctive characteristics of perforated prehistoric ornaments, primarily beads and pendants, found on the Caribbean islands of Curaçao and Bonaire. The production and stylization of these ornaments is briefly compared between the islands, as well as with specimens recovered from sites on the South American mainland.


Trade Beads From Hudson's Bay Company Fort Vancouver (1829-1860), Vancouver, Washington, Lester A. Ross Jan 1990

Trade Beads From Hudson's Bay Company Fort Vancouver (1829-1860), Vancouver, Washington, Lester A. Ross

BEADS: Journal of the Society of Bead Researchers

Archaeological excavations conducted at Hudson's Bay Company Fort Vancouver recovered 100,000+ trade beads of 152 varieties, including 80 varieties of drawn, 57 varieties of wound, 10 varieties of mold-pressed and 3 varieties of blown glass beads, as well as one variety each of "Prosser-molded" ceramic and cut-stone beads. An additional 6000+ beads recovered from excavations at the HBC Kanaka village and riverside complex sites may include 39 additional varieties possibly associated with the HBC occupation: 17 varieties of drawn, 12 varieties of wound, and 5 varieties of mold-pressed glass beads, as well as one variety each of stone ...

Dominique Bussolin On The Glass-Bead Industry Of Murano And Venice (1847), Karlis Karklins Jan 1990

Dominique Bussolin On The Glass-Bead Industry Of Murano And Venice (1847), Karlis Karklins

BEADS: Journal of the Society of Bead Researchers

One of the earliest detailed descriptions of the Venetian bead industry is contained in an obscure book published in French in 1847 by the Venetian glassmaker Domenico Bussolin. Intended as a "Guide for the Foreigner," this work contains much useful information concerning bead manufacturing techniques and the socioeconomic aspects of the industry. To make this text generally available, a translation prepared by Karklins and Adams is provided here.

Beadmaking In Islam: The African Trade And The Rise Of Hebron, Peter Francis Jr. Jan 1990

Beadmaking In Islam: The African Trade And The Rise Of Hebron, Peter Francis Jr.

BEADS: Journal of the Society of Bead Researchers

This paper complements one which appeared in volume 1 of this journal, as it also deals with beads in the Islamic world. However, the present work takes a somewhat different approach, being based primarily on historical sources. It also has a different geographical orientation, dealing with commerce between the Islamic world and the northern portion of Africa. Concentrating mostly on the period from the 12th to the 20th century, it documents the rise of a new beadmaking center at Hebron, in the West Bank. The name "Kano beads" has recently been assigned to one class of Hebron beads, and their ...


Some Improvements To Turner's Algorithm For Bracket Abstraction, Martin W. Bunder Jan 1990

Some Improvements To Turner's Algorithm For Bracket Abstraction, Martin W. Bunder

Faculty of Engineering and Information Sciences - Papers: Part A

A computer handles A-terms more easily if these are translated into combinatory terms. This translation process is called bracket abstraction. The simplest abstraction algorithm-the (fab) algorithm of Curry (see Curry and Feys [6])-is lengthy to implement and produces combinatory terms that increase rapidly in length as the number of variables to be abstracted increases.


Observations And Problems In Researching The Contemporary Glass-Bead Industry Of Northern China, Roderick Sprague, An Jiayao Jan 1990

Observations And Problems In Researching The Contemporary Glass-Bead Industry Of Northern China, Roderick Sprague, An Jiayao

BEADS: Journal of the Society of Bead Researchers

The status of glass-bead manufacturing in northern China is undergoing rapid change due to the development of the plastic-bead industry. Several manufacturing plants, including the large Beijing Glass Ware Factory, are no longer making beads and several other plants are contemplating changes. The variety of domestic glass beads available for purchase today would indicate a greater number of manufacturing sites than are mentioned in the popular literature.

Identification Of Giardia Lamblia-Specific Antigens In Infected Human And Gerbil Feces By Western Immunoblotting, Henry H. Stibbs, Mansour Samadpour, Jerry E. Ongerth Jan 1990

Identification Of Giardia Lamblia-Specific Antigens In Infected Human And Gerbil Feces By Western Immunoblotting, Henry H. Stibbs, Mansour Samadpour, Jerry E. Ongerth

Faculty of Engineering and Information Sciences - Papers: Part A

Western immunoblot analysis of aqueous extracts of feces obtained from five giardiasis patients and from experimentally infected gerbils (Meriones unguiculatus) with rabbit antiserum to Giardia lamblia cysts has revealed antigens of three molecular weight groups. A stepladderlike, evenly-spaced set of strongly reactive antigens (darkest at a molecular weight [m.w.] of 55,000 to 70,000) appeared in the gerbil feces from day 4 (first experiment) or day 2 (second experiment) and lasted to about day 7 but disappeared completely by day 8 and did not reappear later. These antigenic bands were seen in gerbils infected with two isolates of ...


Evaluation Of Dna Probes For Detection Of Shiga-Like-Toxin- Producing Escherichia Coli In Food And Calf Fecal Samples, Mansour Samadpour, John Liston, Jerry E. Ongerth, Phillip I. Tarr Jan 1990

Evaluation Of Dna Probes For Detection Of Shiga-Like-Toxin- Producing Escherichia Coli In Food And Calf Fecal Samples, Mansour Samadpour, John Liston, Jerry E. Ongerth, Phillip I. Tarr

Faculty of Engineering and Information Sciences - Papers: Part A

The use of DNA probes for Shiga-like toxin I (SLT-I) and SLT-II for detection of SLT-producing Escherichia coli (SLTEC) in foods and calf fecal samples was evaluated. Enrichment cultures were prepared from food or fecal samples. Colonies formed by plating of enrichment cultures were probed for SLTEC by colony hybridization. Alternatively, enrichment cultures were analyzed for SLTEC presence by dot blot. The lowest detected concentration of SLTEC in sample homogenates inoculated with E. coli 0157:H7 corresponded to 1.3 CFU/g of sample. Of the 44 food samples and 28 fecal samples from dairy calves tested by the colony ...
