An investigation on the effects of the ball filling on the breakage parameters of natural amorphous silica
(Elsevier B.V., 2016)
The effects of ball filling on the selection (Si) and breakage functions (Bi,j) for the natural amorphous silica were investigated in this paper. At four levels (20%, 30%, 40% and 50%) of ball filling, the selection functions ...
Dichromate and phosphate sorption capacity of bis formyl calix[4]arene on superparamagnetic iron oxide nanoparticles in aqueous phase
(Chemical Publishing Co., 2016)
Calix[4]arene derivatives were added into aqueous phase phosphate and dichromate solutions in order to investigate sorption capacity at pH of 1.5 to 5.5. A 25 mg of polymers magnetic calix[4]arenes derivatives was added ...
Prognostic value of 18F-FDG PET/CT for identifying high- and low-risk endometrial cancer patients
(Studio K Krzysztof Molenda, 2016)
Objectives: To assess the usefulness of adding PET/CT as a preoperative test for determining the extent of endometrial cancer and discriminating low- and high-risk patients to identify candidates for surgical staging. ...
Preparation and characterization of pH responsive poly(methacrylic acid-acrylamide-N-hydroxyethyl acrylamide) hydrogels for drug delivery systems
(John Wiley and Sons Inc., 2016)
In this study, pH responsive polymers composed of methacrylic acid, acrylamide, and N-hydroxyethyl acrylamide were synthesized by free radical polymerization technique. The characterization was done with Fourier transform ...
Wideband long wave infrared metamaterial absorbers based on silicon nitride
(American Institute of Physics Inc., 2016)
In this paper, we present silicon nitride metamaterial absorber designs that accomplish large bandwidth and high absorption in the long wave infrared (LWIR) region. These designs are based on the metal-insulator-metal ...

Objective: To examine the influence of Modified Epley Maneuver on balance in patients with posterior semicircular canal (SCC) benign paroxysmal positional vertigo (BPPV) Design: Retrospective study Setting: Ankara Numune ...
Assessment of ecological status and water quality by using some trophic indices in a Dam Lake
(Scibulcom Ltd., 2016)
The composition and seasonal variations of benthic diatoms of Yedikir Dam Lake were studied using samples collected from two stations between November 2004 and April 2006. The diatom communities were diverse: 81 taxa were ...
Seasonal succession of the phytoplankton community and evaluation of water quality using trophic diatom index in a stream
(Scibulcom Ltd., 2016)
Phytoplankton species composition, seasonal variation and the factors effecting the variation were studied in this study one-year period, from June 2010 to May 2011. Water samples were collected monthly from four stations. ...
Seasonal distribution of epipelic diatom assemblages and relations to environmental variables in a mesotrophic pond
(Scibulcom Ltd., 2016)
The seasonal succession of diatom species in the epipelon of shallow, mesotrophic pond OMU Pond I (Turkey) with special attention to diatoms (particularly Navicula) is described. The composition of epipelic algal assemblages ...
