background: noise prediction is considered to be the best method for evaluating cost-preventative noise controls in industrial workrooms. one of the most important issues is the development of accurate models for analysis of the complex relationships among acoustic features affecting noise level in workrooms. in this study, advanced fuzzy approaches were employed to develop relatively accurate ...

background: the purpose of this research was to determine the traffic noise level and changes in the kerman city, southeast iran in recent years. methods: this cross-sectional study was carried out in 2008 to investigate the existing noise situation in kerman. sound levels (l max , l min , l eq , l 99 , l 90 , l 50 and l 10 ) were determined throughout 13 stations using sound level measurement ...

it is accepted that noise pollution has a major impact on health, such as physical, physiological, psychological and performance related effects, all over the world. this study aims to evaluate noise pollution in four urban parks located in sanandaj city, iran and to zone it in gis environment. sound pressure level (spl) and maximum sound level (lmax) were measured at 45 points (each point was ...

Enzymes perform an essential role in catalysing extensive reactions. Yet, their instability upon repetitive use, as well as their activity inhibition by different solvent remains a cumbersome task. We present here a simple method to immobilize Aspergillus niger lipase (ANL) onto polyaniline–silver functionalized graphene oxide nanocomposites (PANI/Ag/GO), involving the facile synthesis of PANI/...

In this work, the degradation performance of Fe2+/PAA/H2O2 on three typical pollutants (reactive black 5, ANL, and PVA) in textile wastewater was investigated comparison with Fe2+/H2O2. Therein, had a high removal RB5 (99%) mainly owing to contribution peroxyl radicals and/or Fe(IV). Fe2+/H2O2 showed relatively PVA (28%) resulting from ·OH. comparative removals ANL. Additionally, more sensitive...

Argonne National Laboratory (ANL), along with other national laboratories, has been developing a solvent extraction process for partitioning of spent fuel constituents to lead to safer and cheaper disposal of high-level waste. The process, known as UREX+, separates key radionuclides from dissolved spent fuel into: (1) uranium for disposal as LLW, (2) technetium for disposal as HLW, (3) iodine f...

abstract background: previous studies have indicated an unspecific correlation between noise exposure and blood pressure disturbances. blood pressure disturbances could be caused by the environmental hazards such as noise exposure. the aim of this study is to analyze whether there is a relationship between noise exposure and hypertension. methods: atotal sample of 218 workers working in a small...
