advances in grid infrastructure and middleware development have enabled various types of applications in science and engineering to be deployed on the grid. The characteristics of these applications and the diverse infrastructure and middleware solutions developed, utilized or adapted by PRAGMA member institutes are summarized. The applications include those for climate modeling, computational chemistry, bioinformatics and computational genomics, remote control of instruments, and distributed databases. Many of the applications are deployed to the PRAGMA grid testbed in routine basis experiments. Strategies for deploying applications without modifications, and those taking advantage of new programming models on the grid are explored and valuable lessons learned are reported. Comprehensive end to end solutions from PRAGMA member institutes that provide important grid middleware components and generalized models of integrating applications and instruments on the grid are also described. Index Terms—PRAGMA, grid, applications, deployment, strategies, lessons

tuberculosis has shown a speedy worldwide spread. The incidence of drug-resistant Mycobacterium tuberculosis is increasing in almost all industrialized and developing countries. The epidemiology of multiple drug resistance varies in different regions and countries. The aim of this study was to determine the activities of first-line (isoniazid, rifampin, ethambutol and streptomycin) and second-line (kanamycin, para-aminosalicylic acid, ethionamide and capreomycin) antituberculosis drugs on 100 various clinical isolates of M. tuberculosis. Mycobacterium tuberculosis ATCC 27294, ATCC 35838, ATCC 35825 and ATCC 35837 were used for internal quality control. First-line drug resistant strains were isolated from 10 clinical specimens. Six of them showed resistance to a single drug and four to more than one first-line drug. All of the single-drug resistant strains were resistant to isoniazid. Of 100 isolates, 56 were resistant to capreomycin, 41 to kanamycin, 12 to para-aminosalicylic acid and four to ethionamide. All of the first-line drug-resistant strains were found to be susceptible to para-aminosalicylic acid and ethionamide. In view of the above findings, we suggest that clinicians should be well-informed about the current local epidemiology of tuberculosis, and health care institutions should maintain up-to-date drug susceptibility data on the local isolates of M. tuberculosis. Key Words: Mycobacterium tuberculosis, isoniazid, rifampin, ethambutol, streptomycin, kanamycin, para-aminosalicylic acid, ethionamide, capreomycin, susceptibility

Model checking and abstraction

by Peter J. Clarke, Djuradj Babich, Tariq M. King, B. M. Golam Kibria - ACM Transactions on Programming Languages and Systems , 1994
"... software developers are using the Java language as the language of choice on many applications. This is due to the effective use of the object-oriented (OO) paradigm to develop large software projects and the ability of the Java language to support the increasing use of web technologies in business ..."

applications. The recent release of the Java version 5.0 has further increased its popularity due to the inclusion of new features that exist in other OO languages. The transition from Java 1.4.x to Java 1.5.x has provided the programmer with more flexibility when implementing programs in Java. In this paper
