© 2020 Parlar Scientific Publications. All rights reserved.Sediment core samples (H002, H003, H005 and H006) recovered from the basin of Lake Hazar located in the South East Region of Turkey. Core sam¬ ples were collected from the four sampling stations by UWITEC corer to determine diatom flora distri¬ bution in Lake Hazar. Diatom counts and identifica¬ tions were made from the sediments sampled at 1-2 cm intervals. Total of 142 species of diatoms were recorded, most of them were pennate diatoms. Ulnaria ulna, Nitzschia gracilis, Synedra nana, and Cyclotella ocellata dominated the assemblage in the sampling points. Our objective was to investigate the environmental and ecological history of Lake Hazar, and to recover diatom microfossil profils using paleolimnological techniques.

Spatio-temporal distribution of picophytoplankton (Pico-eukaryotes, Synechococcus and Prochlorococcus) abundance in the northeastern mediterranean Kilic, Ece; Uysal, Zahit; Tugrul, Suleyman; Yucel, Nebil (2020-07-01) © 2020 Parlar Scientific Publications. All rights reserved.Primary productivity mostly relies on marine cyanobacteria in the oligotrophic north-eastern Mediterranean (NEM). However, wide shelf basin is fed by nutrient-rich rivers (namely Goksu, Lamas, Seyhan, Ceyhan, Asi) leading to apparent increase in algal production at coastal regions. In the present study, variation of picophytoplankton (pico-eukaryotes, Synechococcus and Prochlorococcus) abundance of at different trophic levels of NEM were investigate...
Sulfate removal from drinking water by commercially available nanofiltration membranes: A parametric study Karabacak, Aslı; Dilek, Filiz Bengü; Yılmaz, Levent; KİTİŞ, Mehmet; Yetiş, Ülkü (2020-01-01) © 2020 Desalination Publications. All rights reserved.The efficacy of nanofiltration (NF) in removing sulfate from a high sulfate content (370–460 mg/L) surface water was investigated. NF tests were carried out using a laboratory-scale cross-flow NF module operated in total-recycle (full-recycle) mode. Membranes of varying characteristics; namely, DK-NF (Desal DK: GE Osmonics, USA), DL-NF (Desal DL: GE Osmonics, USA), and NF270 (Dow Filmtec Co., USA) were tested, and the effects of main operational paramete...
Prediction of yields and composition of char from fast pyrolysis of commercial lignocellulosic materials, organosolv fractionated and torrefied olive stones Magalhães, Duarte; Gürel, Kaan; Matsakas, Leonidas; Christakopoulos, Paul; Pisano, Italo; Leahy, J.J.; Kazanç Özerinç, Feyza; Trubetskaya, Anna (Elsevier BV, 2021-04-01) © 2020 The Author(s)This study investigated the fast pyrolysis behaviour of torrefied olive stones, fractionated olive stones and lignocellulosic commercial compounds. Olive stones were reacted in a continuous industrial torrefaction unit. The olive stones were also fractionated into their main components in an organosolv reactor at temperatures from 170 to 190 °C in both the presence and absence of an acidic catalyst. All samples were reacted in a wire mesh reactor at different temperatures (800–1150 °C) a...
Investigation of optical characteristics of PbMoO4 single crystals by spectroscopic ellipsometry Delice, S.; Isik, M.; Hasanlı, Nızamı; Darvishov, N.H.; Bagiev, V.E. (2022-07-01) © 2022 Elsevier GmbHIn this study, we investigated the optical properties of PbMoO4 single crystals grown by Czochralski method. Spectroscopic ellipsometry measurements were carried out in the energy region between 1.0 and 5.5 eV at room temperature. X-ray diffraction measurements were achieved for structural characterization. The resulted pattern exhibited one peak belonging to (200) plane. Spectral variations of complex dielectric function, complex refractive index, absorption coefficient and dissipation ...
Investigation of Mars' ionospheric response to solar energetic particle events Uluşen, Demet; Brain, David A.; Luhmann, Janet G.; Mitchell, David L. (2012-12-11) We investigate the effects of solar energetic particle (SEP) events on the Martian ionosphere using observations from the Mars Global Surveyor (MGS) Electron Reflectometer (ER) and Radio Science (RS) experiments. Although MGS/ER is not designed to measure solar storm particles, it detects SEPs as increased instrument background. Using this proxy for SEP fluxes near Mars, we compare electron density profiles obtained from the RS experiment during periods of high and low SEP activity. Six case studies show no...
