The effects of Co addition on the mechanical and microstructural properties of the matrix material of a Fe-based marble cutting tool
(Redakcia Kovove Materialy, 2016)
In this study, four different kinds of marble cutting matrices with a base composition of Fe-Cu-Sn and with variable amounts of Co powder were produced. For compaction, hot sintering process was carried out at 850 degrees ...
Genetic characterization of the Akkaraman, Morkaraman and Karayaka sheep through microsatellite variation
(Agricultural Research Communication Centre, 2015)
Genotypes have to be controlled periodically and necessary-precautions should be taken in order to ensure that animal biodiversity is not lost. In this study, the genotypes of the Akkaraman, Karayaka and Morkaraman species ...
Modeling of Co(II) adsorption by artificial bee colony and genetic algorithm
(Techno-Press, 2018)
In this work, it was investigated the usability of artificial bee colony (ABC) and genetic algorithm (GA) in modeling adsorption of Co(II) onto drinking water treatment sludge (DWTS). DWTS, obtained as inevitable byproduct ...
Synthesis of cyclohexane derivatives including Br, Cl, N, O, and S at 1,2,4,5-positions: selectivity in addition reactions
(Pergamon-Elsevier Science Ltd, 2014)
Brominations of mono addition products of 1,4-cyclohexadiene with 2,4-dinitrobenzenesulfenyl chloride (RSCI) selectively gave 1R(S),2R(S),4R(S),5R(S)-4,5-dibromo-2-(2,4-dinitrophenylthio)cyclohexyl acetate and 1R(S),2R(S ...
Entropy generation of nanofluid flow in a microchannel heat sink
(Elsevier Science Bv, 2018)
Present study aims to investigate the effects of the presence of nano sized TiO2 particles in the base fluid on entropy generation rate in a microchannel heat sink. Pure water was chosen as base fluid, and TiO2 particles ...
Safety and Effectiveness of 5-mm and 10-mm Electrothermal Bipolar Vessel Sealers (LigaSure) in Laparoscopic Resections for Sigmoid Colon and Rectal Cancers
(Mary Ann Liebert, Inc, 2012)
Background: LigaSure (TM) (Covidien, Mansfield, MA) has been used in cases undergoing laparoscopic colon and rectal resections. This study aims to analyze the efficacy and safety of the 5-mm and 10-mm devices. Subjects and ...
Automated Model Updating Effect on the Linear and Nonlinear Dynamic Responses of Historical Masonry Structures
(Springer, 2018)
Finite element models supply the simulation of the problems to obtain the structural behaviors under different loading conditions. The updating processes based on changing the uncertain parameters such as material properties, ...
Estimation of the temperature profiles of reinforced concrete cross sections exposed to standard fires by using artificial neural networks with different topologies
(Wiley, 2016)
The thermal analysis in structural members can be extremely complex, especially for materials that retain moisture and have a low thermal conductivity. The simplest method of defining the temperature profile through the ...
Effectiveness of Black Mulberry Molasses in Prevention of Radiotherapy-Induced Oral Mucositis: A Randomized Controlled Study in Head and Neck Cancer Patients
(Mary Ann Liebert, Inc, 2017)
Objectives: Radiation-induced oral mucositis is one of the problems experienced by 70%-80% of patients receiving radiation therapy (RT). This randomized controlled trial assessed the effectiveness of black mulberry molasses ...
The effects of chemical attacks on physical and mechanical properties of concrete produced under cold weather conditions
(Elsevier Sci Ltd, 2014)
This study investigates the effects of corrosive conditions on the physical and mechanical properties of concrete produced in cold weather. 30% calcium nitrate and 5% hydroxyethylaminemixture (HEA) were used as additives ...
