evaluating the quality and quantity of water resources is crucial for a sustainable development. one of the simplest methods that is able to indicate the conditions of water quality in a short period and at a low cost, compared with the physicochemical methods, is by using the biological water quality indices. identifying the contamination of water resources using biomarkers, especially indices...

Water quality indices (WQIs), which translate numerical values of several water quality characteristics of a sample into a single value, play a very important role in the monitoring, comparison and control of water quality. The WQIs of modern and post-modern times have been almost exclusively based on physical and chemical characteristics, and have seldom included 'biological' characteristics o...

The author shows that the use of high-resolution spectrum estimation methods instead of Fourier-based techniques can improve the accuracy of measurement of spectral parameters of distorted waveforms encountered in power systems, in particular the estimation of the power quality indices (such as inter/harmonic groups and subgroups). The comparison of the frequency and amplitude estimation error,...

The measurement of the impact of skin diseases on patients' quality of life is important. This review explains the reasons for this, explains the main methods of measuring quality of life in dermatology and describes recent research in this area. Virtually all aspects of patients' lives can be affected by skin disease. It is important to be able to measure this effect for clinical, therapeutic ...

introduction: periodontal disease is one of the most important diseases in health topics. the aim of this study was to determine the effect of periodontal treatment on quality of life. materials and methods: in this quasi-experimental, interventional study, 45 patients with chronic periodontitis were asked to complete the “quality of life” questionnaire before starting the treatment and four mo...
