Oil agglomeration of a lignite treated with microwave energy: Effect of particle size and bridging oil
(ELSEVIER SCIENCE BV, 2005)
Oil agglomeration of Sivas-Divrigi (S-D) Uluayir lignite fines was carried out using kerosene and kerosene-extract oil (which was obtained from lignite treated with microwave energy) mixture as a bridging oil. The effects ...
Lead removal by polyacrylamide-bentonite and zeolite composites: Effect of phytic acid immobilization
(ELSEVIER SCIENCE BV, 2005)
Polyacrylamide (PAA)-bentonite (B) and zeolite (Z) composites were prepared by direct polymerization of PAA in suspensions of B and Z. Phytate (Phy) immobilized onto the composites to obtain their Phy modifications. FT-IR ...
Determination of trace elements in fly ash samples by FAAS after applying different digestion procedure
(ELSEVIER SCIENCE BV, 2005)
The fly ash samples obtained from Kangal Power Plant were prepared for FAAS analysis by a new approach. The trace elements of the fly ash samples were leached with appropriate solvents under suitable conditions. The leaching ...
Dragline cycle time analysis
(NATL INST SCIENCE COMMUNICATION-NISCAIR, 2005)
Draglines operate in a cyclic nature. Excluding the infrequent walking, a dragline spends its major operational time by digging the dirt and paying it out on a spoil pile. Considering the fact that a dragline performs tens ...
Molecular modeling study on the relative stabilities of the flotation products for arsenic-containing minerals: dixanthogens and arsenic(III) xanthates
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005)
The interactions of As(III) ion with C2H5OCS2- and C2H5SCS2-, known as the most popular collector ions, were studied by density functional theory (DFT) at the B3LYP/6-31G** level in connection with the arsenic-containing ...
The interaction of N2O with ZSM-5-type zeolites: A transient, multipulse investigation
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005)
The interaction of N2O with MFI zeolites was investigated by a multipulse transient response method at 250 degrees C with subsequent temperature-programmed desorption. It was shown that the active sites for the formation ...
Nasal septal suture technique versus nasal packing after septoplasty
(OCEAN SIDE PUBLICATIONS INC, 2005)
Background: The aim of this study was to compare eustachian function and blood gas changes with nasal packing (NP) and nasal septal suturing (NSS) after septoplasty. Methods: Eighty patients who have nasal septal deviation ...
Combined biological removal of nitrate and pesticides using wheat straw as substrates
(ELSEVIER SCI LTD, 2005)
Nitrate and the selected pesticides, trifluralin, fenitrothion and endosulfan (alpha + beta) removal was studied in an up flow biological denitrification reactor packed with wheat straw as carbon source and support particles ...
In vitro antioxidant activities of the methanol extracts of five Allium species from Turkey
(ELSEVIER SCI LTD, 2005)
This study was designed to examine the in vitro antioxidant activities of the methanol extracts of five Allium species, namely Allium nevsehirense, A. sivasicum, A. dictyoprosum, A. scrodoprosum subsp. rotundum and A. ...
Blood pressure, heart rate and temperature variability during periodontal surgery
(UNIV WEST INDIES FACULTY MEDICAL SCIENCES, 2005)
The aim of the present study is to investigate changes in blood pressure, pulse rate and temperature before and after periodontal surgery. The study included 12 7 normal healthy patients (43 males, 84 females) with age ...
