Background: Today, the effects of environmental pollution on human life and human needs, which reduces the level of community health caused by traffic noise in large cities, are clearly visible by creating irritation and pathogenic conditions. The aim of this study was to assess the risk of noise pollution resulted from central traffic in Shiraz by analyzing its indicators and related componen...

Merged indexes are B-trees that contain multiple traditional indexes and interleave their records based on a common sort order. In relational databases, merged indexes implement “master-detail clustering” of related records, e.g., orders and order details. Thus, merged indexes shift de-normalization from the logical level of tables and rows to the physical level of indexes and records, which is...

Previous authors have shown how to build FM-indexes efficiently in external memory, but querying them efficiently remains an open problem. Searching näıvely for a pattern P requires Θ(|P |) random access. In this paper we show how, by storing a few small auxiliary tables, we can access data only in the order in which they appear on disk, which should be faster. An FM-index [4] is a compressed r...

The present study was carried out near an industrial area with a high-density urban population and large-scale agricultural activities. These anthropogenic activities lead to groundwater pollution depletion of the water table. This attempted classify sources hydrochemical facies that help ensure suitability for agriculture drinking. Irrigation indexes, quality index (WQI), principal component a...

To evaluate the clinical usefulness of measuring transthoracic electrical impedance in patients with pulmonary edema, we studied 27 normal subjects and 33 patients. In normal subjects, impedance increased when body position changed from supine to standing (p less than 0.01) and when lung volume increased from residual volume to total lung capacity (p less than 0.01). Impedance values vari7 omeg...

In this study, biogas residue fermented by engineering was used as compost raw material, and different quality biochar added in the composting process to explore effect of on transformation heavy metals process. The comprehensively analyzed with potential ecological risk assessment redundancy analysis. addition 10.0% during had a strong passivation exchangeable Cu Cd, rates 11.75 63.89%, respec...

This report describes the results of a set of experiments conducted with AIMS (Assisted Indexing at Mississippi State), a system that aids human document analysts in the assignment of indexes to physical chemistry journal articles. We defined four different experiments using four different combinations of portions of an article (such as the title and the abstract) to determine which portions of...
