Adsorption of UV254 in Kerian River water onto ZeliacTM: Analysis using linear and non-linear forms of isotherm models

by

Hamidi Abdul Aziz et al. View all

Water Resources Management

The composite media, Zeliac TM was developed with the initial aim to provide low cost adsorbent with promising adsorption capacity. This study was conducted to investigate the removal of UV absorbance at 254 nm (UV 254) in Kerian river water using Zeliac TM as the media. Batch experiments study was...

Modeling a Drought Index Using a Nonparametric Approach

by

Olya H. et al. View all

General

Alternatively, to other studies that used parametric distributions (e.g. Gamma) in the estimation of the Standardized Precipitation Index (SPI), this study aims to apply a nonparametric method based on Kernel Density Estimator (KDE) for calculating the SPI. Results of the proposed method were...

A multi-stage methodology for selecting input variables in ANN forecasting of river flows

by

Dionysia Panagoulia et al. View all

General

The scientific community has recognized the necessity for more efficiently selected inputs in artificial neural network models (ANNs) in river flows and has worked on this despite some shortcomings. Moreover, there is none or limited inclusion of ANN inputs coupled with atmospheric circulation under...

Evaluation of three pollutant dispersion models for the environmental assessment of a district in Kocaeli, Turkey

by

Kazım Onur Demirarslan et al. View all

Air Quality

Air Quality Modeling is a method used to manage urban air quality. Various pollutant dispersion models are available, and each of these models is characterized by its own advantages and disadvantages. Thus, we aimed to evaluate the advantages and disadvantages of the models and to determine their...

The contribution of natural and artificial regeneration at the restoration of fire-affected peri-urban forest of Thessaloniki (Northern Greece)

by

Chatzichristaki Chrysoula et al. View all

General

In this study, the post-fire regeneration of three coniferous species ( Pinus brutia, Cupressus sempervirens and Cupressus arizonica) was examined in the peri-urban forest of Thessaloniki, Northern Greece. The wildfire took place in July 1997 and burned almost 60% of the forest vegetation. During...

Synthesis and application of CeO2/sawdust nanocomposite for removal of As (III) ions from aqueous solutions using a fixed bed column system

by

Reza Ansari et al. View all

Wastewater treatment

In this study, nanocomposite of ceria sawdust (CeO 2/SD) synthesized by precipitation method was utilized for removal of As (III) ions from aqueous solutions. Study of the process was done in column system. Characterization of the nano sized adsorbent particles was carried out using XRD and SEM...
