An Expert System for Managing an Activated Sludge Wastewater Treatment Plant

A diagnostic expert system for an activated sludge wastewater treatment plant has been designed to link with a relational database management system for obtaining operational parameter values that are used by the program to diagnose operational problems that may occur in the process. The problems that are dealt with by the system are bulking sludge, floating sludge, defloculation, ashing, solids washout, foaming problems, high soluble effluent BOD and problems in the aeration system. The link between the expert system and the database is accomplished via programming that is initiated by the expert system program. The operator of the system is not required to perform any action in order for the appropriate retrievals of operational parameter values to occur. The system is designed such that parameter values are retrieved from the database if such a database exists and contains appropriate values and, if no such database exists or if the appropriate values are not present, the operator is queried for the parameter values. Since many wastewater treatment plants maintain database management systems for operational parameter values, such an expert system has advantages over stand alone systems. However, an override of the database query is possible, making the system useful for experimental queries and for training

The Round Table on Women's Issues snapshot project: the status of women in libraries internationally

This project was commissioned by the Round Table on Women's Issues (RTWI) at the 66th IFLA conference. The Round Table on Women's Issues is a sub-division of IFLA which concerns itself extensively with questions and issues that have special relevance for women in the library profession and in the user community. Further it develops programmes designed to enhance the opportunities and the image of these two groups of women. The Round Table on Women's Issues promotes the collection, research, publication and dissemination of information on the status of women in librarianship. Another concern is to identify discrimination in all forms, and disparities in resources, programmes, and opportunities relating to women in librarianship. At the 66th Conference, members of the Round Table discussed the Association of Research Libraries' Annual Salary Survey, 1999-2000 and noted that the average salary for female directors (USD 132,000) in United States university libraries was slightly higher than the average salary of male directors (USD 125,000) (pp. 16-18). There is now the highest number of women in top administrative positions than there has been before: 54 women out of a total of 111 directorships. This was of course the good news.The bad news was that the overall salary for women in research and academic libraries in the USA was still only 94 percent that of men. During the 19 years that statistics have been gathered women have been gradually closing the earnings gap, as in 1980 they earned only 87 percent, but it is a slow process. Overall, men represent only 35 percent of the workforce among professional librarians. The Round Table felt it would be interesting to discover how this compared with salaries in other countries and other sectors. This could form the basis for some comparative statistics if other members of the group could follow up. Although aware that delegates at IFLA conferences were not representative of the profession as a whole, it was felt that it might be possible to conduct a 'snapshot' project of delegates, women officers and committee members at IFLA's 67th conference to ascertain the status of women librarians internationally. Sandra Parker and Pat Gannon-Leary from the Information Management Research Institute, University of Northumbria School of Information Studies, obtained an IFLA small grant to undertake this work and to report on findings at the 68th IFLA conference

An Evaluation of the Effect of Discharging a High Quality Effluent into a Small Ozark Mountain Stream

Recently the newly constructed Fayetteville wastewater treatment plant went on line and directed a portion of its discharge to a point in the Mud Creek drainage basin that had previously not received any effluent. Prior to the discharge, a background study had been performed to establish the water quality in the basin. The background data, when compared to the data collected by this study, allowed any alteration of the stream water quality to be evaluated. Also the modeling procedure used to set the effluent limits for the treatment plant was analyzed. All stream data were compared to the limits set forth for surface water quality by the Department of Pollution Control and Ecology. The new discharge had some effect on the receiving stream, however, the stream still meets Arkansas water quality standards for all parameters

Local Water Resource Information Management System

A Beaver Lake water quality database has been designed as a relational database. It has been implemented using software called R:base 5000, a system available for microcomputers using MS- or PC- DOS operating systems. The data in the database include that concerned with the author(s), title, date of publication, agency doing the study, agency funding the study and complete reference for the document. Other aspects of the database are designed to allow retrievals based on any author, study dates, parameters measured and keywords

Use of Microcomputers to Aid Wastewater Treatment Plant Operations

This report presents the development of a microcomputer based data management system for wastewater treatment plants. The relational database model was shown to be well suited for data management applications in wastewater treatment plants. A general data management system was developed for use with a microcomputer using a commercially available relational database management system. Use of the developed system requires no special computer training. The system was tailored for use at the wastewater treatment plant at Springdale, Arkansas. The capabilities of the system were demonstrated with actual data from the Springdale plant

Violence on campus: Practical recommendations for legal educators

Recent rampage killings compel greater attention to anger and violence on the college campus. In each of these tragic mass murders, vengeful individuals sought to address perceived grievances against faculty and/or other employees of the university. In each of these situations, numerous clues of impending violence were evident. Sadly, however, in each of these cases the schools failed to take preventive actions. While prediction of violent behavior will never be an exact science, universities must begin to enact violence prevention strategies. Maintaining an attitude that \u27this couldn\u27t happen here\u27 hampers the necessary education of faculty, staff, and security personnel. Our purpose in this paper is to provide guidelines for dealing with angry students. Additionally, we will point out characteristics of potentially violent students and suggest some violence prevention measures. Although we will touch on security issues, our goal is to help law educators prevent students from erupting violently rather than to stop a mass murder already in progress

Wie hilfreich sind "ethische Richtlinien" am Einzelfall?: Eine vergleichende kasuistische Analyse der Deutschen Grundsätze, Britischen Guidelines und Schweizerischen Richtlinien zur Sterbebegleitung

Zusammenfassung: Entscheidungen der Therapiebegrenzung und in der Betreuung am Lebensende sind häufig komplex und von ethischen Problemen begleitet. Im Mittelpunkt der Untersuchung steht die entscheidende Frage, wie hilfreich existierende "Ethik-Richtlinien", die eine ethische Orientierung bei solchen Entscheidungen geben sollen, in der klinischen Praxis tatsächlich sind. Die Frage, welchen Nutzen "Ethik-Richtlinien" bei der Entscheidungsfindung haben oder haben können, wird hier exemplarisch an einem klinischen Fallbeispiel aus einer Ethik-Kooperationsstudie in der Intensivmedizin analysiert. Vergleichend werden hierzu "Ethik-Richtlinien" aus Deutschland, der Schweiz und aus Großbritannien herangezogen, die Gegenstand eines internationalen Projekts zur Analyse von Richtlinien waren. Die Möglichkeiten und Grenzen einer ethischen Orientierung an "Ethik-Richtlinien" bei Entscheidungsproblemen der Therapiebegrenzung und in der Betreuung am Lebensende werden anhand der Fallstudie diskutiert und illustriert. Abschließend werden Schlussfolgerungen für die Entwicklung ethischer Richtlinien für die klinische Praxis formulier
