the continuous addition of industrial, municipal, and agricultural effluents to the environment has led to a great increase of toxic pollutants. it is well known that these pollutants are hazardous to animals, plants, microorganisms, and other living organisms including humans. as a result, effective technologies should be developed to remove these contaminants. biological remediation, as an ec...

Successful river flow forecasting is a major goal and an essential procedure that is necessary in water resource planning and management. There are many forecasting techniques used for river flow forecasting. This study proposed a hybrid model based on a combination of two methods: Self Organizing Map (SOM) and Least Squares Support Vector Machine (LSSVM) model, referred to as the SOM-LSSVM mod...

Self-sustained Treatment for Active Remediation (STAR) is a thermal remediation technology that uses smouldering, flameless form of combustion, destroying organic contaminants in soil. Injected cold air flowing through the soil to treatment zone supports release sufficient energy maintain self-sustained reaction and propagation contaminated as long airflow local exceeds minimum value. However, ...

in recent years, the water quality of karun river, iran, has been affected by different pollutant loads such as agricultural drainages, municipal and industrial wastewaters.water quality index (wqi) and gis as an efficient tool can be used to provide necessary support for decisions of the management actions in this river and also capability of time series models can be beneficial for forecastin...

The water quality of urban rivers in China has undergone significant improvement since the 13th Five-Year Plan period (2016–2020). Among these, Shenzhen are most representative. Assessing historical trends and analyzing driving forces river is great importance provides valuable insights. This study selects two typical watersheds, Maozhou River Longgang River, to explore how link with control pr...

This study proposed an integrated valorisation system, by combining adsorption and electro-Fenton processes for fast effective micropollutant remediation of a complex pharmaceutical mixture. The pharmaceuticals venlafaxine, fluoxetine trazodone, commonly detected in the environment (river water sediment), were selected this as target pollutants. Initially, degradation process ternary mixture wa...

INTRODUCTION A mercury (Hg) processing plant previously operating in KwaZulu-Natal Province (South Africa) discharged Hg waste into a nearby river system causing widespread contamination since the 1980s. Although the processing plant ceased operation in the 1990s, Hg contamination (due to residual Hg) remains significant. Previous studies in the area since the plant's closure have found elevate...

Considered signs of decreased welfare--abnormal behaviors such as self-injury and self-abuse among nonhuman primates housed in the laboratory--may put into question the validity and reliability of scientific research using these animals as models. Providing environmental enrichment decreases the incidence of some undesirable behaviors but is often unsuccessful at ameliorating the most severe ty...
