An investigation of anthropogenic pollution in soil samples from residential areas in Erzincan city center and its vicinity by evaluating chemical factors
(Springer Heidelberg, 2018)
To measure heavy metal pollution, 42 different soil samples were collected and analyzed from the center, cities, and villages of Erzincan. Average element concentrations in the soil samples in micrograms per gram were as ...
Manganese adsorption by iron impregnated pumice composite
(Elsevier Science Bv, 2017)
Manganese (Mn) is often present at high concentrations in ground and surface waters. Industrial discharges are also a major source of Mn pollution in the environment. Adsorption is a widely studied technique to abate Mn ...
Assesment of Chemical Tretability of Fur-Suede Processing Wastewater Together with Toxicity Removal
(Yildiz Technical Univ, 2018)
The aim of this study was to assess the conventional coagulation/flocculation treatability efficiency and the toxicity effect of chemically treated effluent on Daphnia magna for fur-suede processing wastewater. Three ...
Utility of a source-related matrix in basin management studies: a practice on a sub-Basin in Turkey
(Springer Heidelberg, 2021)
According to the water framework directive (WFD), the chemical status should be determined for each water body in a basin through monitoring and evaluation studies, and the gap between the status of water bodies and good ...
The Investigation of Toxic Element Pollution and Radioactivity Analyses of Marine Sediments in the Gulf of Gemlik (Bursa, Turkey)
(Corvinus Univ Budapest, 2021)
In this study, the Toxic element pollution and radioactivity of marine sediments in the Gulf of Gemlik was determined. Enrichment factor (EF) and Pollution index (PI) analyses have been applied to determine toxic element ...
Treatment of organic peroxide containing wastewater and water recovery by fenton-adsorption and fenton-nanofiltration processes
(Academic Press Ltd- Elsevier Science Ltd, 2021)
Treatment of organic peroxide-containing chemical industry wastewater by oxidation methods and recovery of water by the adsorption and nanofiltration (NP010) methods were investigated in this study. The COD and TOC removal ...
Nitrite and nitrate inhibition thresholds for a glutamate-fed bio-P sludge
(Pergamon-Elsevier Science Ltd, 2021)
Enhanced biological phosphorus removal (EBPR) is an efficient and sustainable technology to remove phosphorus from wastewater. A widely known cause of EBPR deterioration in wastewater treatment plants (WWTPs) is the presence ...
Memristor Based Sallen-Key Filters
(Gazi Univ, Fac Engineering Architecture, 2015)
In 1971, memristor is claimed as a missing circuit element and almost 40 years later than its prediction a memristive system behaving as a memristor has been found in 2008. Memristor is accepted by many as the new and the ...
Performance Analysis of a Memristor - Based Biquad Filter Using a Dynamic Model
(Soc Microelectronics, Electron Components Materials-Midem, 2014)
New kinds of programmable amplifiers, adaptive filters, and programmable oscillators can be designed using a new fundamental circuit element memristor. Application of the memristor to analog filters can result in many new ...
A new memristor-based low-pass filter topology and its small-signal solution using MacLaurin series
(Natl Inst Optoelectronics, 2015)
In this work, a new memristor-based low-pass filter topology is suggested. Memristor-based filters are nonlinear circuits and many of them cannot be solved analytically. To find an approximate analytical solution of the ...
