Embankment Design on Soft Clays
(Asce-Amer Soc Civil Eng, 1991)A new design procedure for stage-constructed embankments on soft clays is developed. The critical-state theory is applied and the plastic behavior of normally consolidated clays is taken into account. In the stage construction ... -
Epoxidation of Styrene with Aqueous Hypochlorite Catalyzed by a Manganese (III) Porphyrin Bound to Colloidal Anion-Exchange Particles
(1991)Epoxidation of styrene in aqueous sodium hypochlorite solution was catalyzed by the tetrasodium salt of 5,10,15,20-tetrakis(2,6-dichloro-3-sulfonatophenyl)porphinatomanganese(III) chloride (1). Manganese porphyrin 1 was ... -
Prediction of ripping machine performance in terms of rockmass properties
(1991)The rockmass parameters that affect the productivity of tractor mounted ripping are briefly reviewed. The results of a number of field ripping trials in a variety of sedimentary rocks on the Western Lignite opencast mines ... -
A-type proanthocyanidins from Prunus spinosa
(1991)The range of natural dimeric A-type proanthocyanidins is extended by identification of ent-epicatechin-(4? › 8; 2? › O › 7)-catechin and ent-epiafzelechin-(4? › 8;2? › O › 7)-epicatechin. They are accompanied in the flowers ... -
Ziziphora tenuior L., a new source of pulegone
(1991)The volatile constituents of Ziziphora tenuior L. (Lamiaceae), from two different regions of Turkey, were studied for the first time. Twenty-six compounds, out of the 33 detected were identified by means of capillary GC ... -
The essential oil of Origanum minutiflorum O. Schwarz and P. H. Davis
(1991)The oil of two collections of Origanum minutiflorum of Turkish origin was examined by GC and GC/MS. Forty-three constituents were identified with carvacrol (75.4–82%) being in most abundance -
A Constitutional Investigation of the Mo-Pd-Rh Ternary-System At 1100-Degrees-C
(Elsevier Science BV, 1991)Phase relations in the system Mo-Pd-Rh were studied at 1100-degrees-C using conventionally melted and ultrarapidly solidified samples. Optical microscopy, X-ray diffraction, scanning electron microscopy and electron probe ... -
Aristolochic acids and aristolactams from Aristolochia auricularia
(1991)A methanolic extract of the roots of Aristolochia auricularia was found to contain seven known compounds, aristolochic acids I, II, III and IV and aristolactams I, II and III. In addition, four novel compounds, the methyl ... -
Novel Method for the Analysis of Rlc Circuits
(Taylor & Francis LTD, 1991)The lagrangian formulation of classical mechanics is applied to RLC circuits. The generalized power function is introduced and the reduced Lagrange equations are used in the analysis of the system. This new method seems ... -
Modeling and applications of space manipulators
(Publ by ASME, New York, NY, United States, 1992)To control robot or teleoperated manipulators in space, the motion of the satellite (which is actually the base of the manipulator) which will move due to the force exerted by the moving manipulator, must be considered. ... -
Froth washing technology in mechanical flotation machines
(1992)This paper concentrates on the five recent plant trials/applications of froth washing in mechanical flotation cells in North America. Increased froth cleaning yielded better upgrading and some cases slightly improved ... -
Human Umbilical-Cord Vein Grafts for Replacement of the Superior Vena-Cava
(Edizioni Minerva Medica, 1992)We have used umbilical veins as experimental graft materials for superior vena cava replacement. The patency rate of these grafts in 25 laboratory animals was 96%; the mortality and graft thrombosis rate was 4%. ... -
The Factors Effecting Complement Activation in Open-Heart-Surgery
(Edizioni Minerva Medica, 1992)The activation of the complement system was investigated in 10 patients with rheumatic valve disease having heart surgery. The C3c, C4, leukocyte count and polymorphonuclear neutrophil count were determined in the blood ... -
Removal of Dye Stuffs From Waste-Water - Electrocoagulation of Acilan Blau Using Soluble Anode
(Taylor & Francis Inc, 1992)An attempt was made to remove a dye such as Acilan Blau using an electrochemical method. In the process a bipolar packed bed electrochemical reactor consisting of soluble electrodes was used and operated in the batch mode. ... -
