today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
Data mining technology allows large volumes of data to be exploited for discovering previously unknown,possibly useful knowledge. The speed and extent of developments in information technologies have increased the power and potential of data mining.However, the privacy of personally sensitive information is not respected generally in the process,which creates ethical and legal problems in some ...
background: primary health care is the major infrastructure of health care systems. it is clear that making and improving primary health care information systems would not be possible without awareness of their condition. therefore, this comparative study was conducted in order to determine the situation of primary health care information systems in health centers of tehran, iran. methods: this...
Introduction: Admission and medical record system (AMRS) is one of the most important subsystems of hospital information system, which is used by many users in admission, discharge, and health information management. Interface usability problems can reduce user speed, precision, and efficiency in user-system interaction. This study aimed to identify the usability problems of AMRS in a hospital ...

Purpose: This paper aims to evaluate the security of web-based information systems of Iran Public Libraries Foundation (IPLF). Methodology: Survey method was used as a method for implementation. The tool for data collection was a questionnaire, based on the standard ISO/IEC 27002, that has the eleven indicators and 79 sub-criteria, which examines security of web-based information systems of IP...
Access to justice has become an important issue in many justice systems around the world. Increasingly, technology is seen as a potential facilitator of access to justice, particularly in terms of improving justice sector efficiency. The international diffusion of information systems (IS) within the justice sector raises the important question of how to insure quality performance. The IS litera...
Accurate performance evaluation of any deployed system is important to its user community. The distributed nature of network measurement infrastructures escalates the complexity of this performance evaluation. In this work, we evaluate the performance of a measurement service, the S system [3]. We measure the performance in terms of resource utilization and response times under increasing measu...
