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 ...
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 ...
Spatiotemporal variability of four precipitation-based drought indices in Xinjiang, China
(Springer Wien, 2017)
Global increases in duration and prevalence of droughts require detailed drought characterization at various spatial and temporal scales. In this study, drought severity in Xinjiang, China was investigated between 1961 and ...
Control of dry and wet Januaries and winters in the Mediterranean Basin by large-scale atmospheric moisture flux and its convergence
(Elsevier, 2018)
The associations between the seasonal moisture budget (precipitation minus evaporation) and atmospheric and oceanic teleconnections related with dry and wet conditions in the greater Mediterranean Basin are investigated. ...
Axial dynamics of a nanorod embedded in an elastic medium using doublet mechanics
(Elsevier Sci Ltd, 2017)
This study investigates the axial vibration of carbon nanotubes (CNTs) embedded in an elastic medium using scale dependent doublet mechanics (DM) theory. Governing equations and all boundary conditions of CNTs are derived ...
Job and Personnel Assessment in the Apparel Industry Using Fuzzy Logic
(Inst Chemical Fibres, 2014)
In this study, a new approach to job and personnel assessment for the apparel industry is presented. The purpose of this new approach is to evaluate both qualitative and quantitative data at the same time. For this purpose, ...
