Investigation of the structure of and the properties of the potentially tautomeric 1,2,3,4-tetrahydro-5,7-dimethyl-6H-pyrrolo[3,4-d]pyridazine-1,4-diones in the gaseous and aqueous phases using the AM1 semi-empirical method
(Elsevier Science BV, 1998)
Potentially tautomeric 1,2,3,4-tetrahydro-5,7-dimethyl-6H-pyrrolo[3,4-d]pyridazine-1,4-diones and their fixed tautomeric forms have been studied in order to predict their tautomeric equilibrium constants and pK(a) values ...
Inhibitory and Stimulatory Effects of Cumin, Oregano and Their Essential Oils on Growth and Acid Production of Lactobacillus-Plantarum and Leuconostoc-Mesenteroides
(Elsevier Science BV, 1991)
Cumin at concentrations of 0.5, 1.0 and 2.0 % (w/w) stimulated growth and acid production of Lactobacillus plantarum and Leuconostoc mesenteroides in a liquid medium. Essential oil from cumin at high concentrations (300 ...
A novel approach to isolated word recognition
(IEEE-Inst Electrical Electronics Engineers Inc, 1999)
A voice signal contains the psychological and physiological properties of the speaker as well as dialect differences, acoustical environment effects, and phase differences. For these reasons, the same word uttered by ...
Self-dual gauge fields in eight dimensions
(1997)
Self-dual gauge fields in even dimensional spaces are characterised by a set of constraints on the eigenvalues of F. We derive a new topological bound (Latin small letter esh sign)M(F, F)2 ? ?M P12 on a compact 8-manifold ...
Downhill walk from the top of a hill by evolutionary programming
(IEEE Computer Society, 1999)
When we search for an infinitely large number of solutions by evolutionary algorithms, it is helpful to learn the topology of the fitness landscape to know whether the solutions we obtained are representative samples of ...
Beneficial-Effects of Hydrogen Pressure in the Pyrolysis of Biomass - a Study of Euphorbia-Rigida
(Elsevier Science BV, 1993)
Fixed-bed pyrolysis and hydropyrolysis experiments at different temperatures and pressures have been conducted on a sample of Euphorbia Rigida extracted with n-hexane and methanol to remove low molecular mass terpenoids ...
Oil production from an arid-land plant: Fixed-bed pyrolysis and hydropyrolysis of Euphorbia rigida
(Butterworth-Heinemann LTD, 1996)
Fixed-bed pyrolysis and hydropyrolysis experiments at different temperatures, heating rates and pressures have been conducted on a sample of Euphorbia rigida to investigate the product yields and characteristics. In hydrogen ...
Thioethers in Urine of Sterilization Personnel Exposed to Ethylene-Oxide
(Blackwell Science LTD, 1992)
Biological monitoring of exposure to ethylene oxide (EO) was carried out in 31 hospital workers in the sterilization facilities of five hospitals. The excretion of total thioethers was determined in the urine of sterilization ...
Fındık kabuklarından hızlı piroliz yöntemiyle sentetik sıvı yakıt eldesi
(1998)
Bu çalışmada, fındık kabuklarının sabit yataklı borusal reaktörde farklı piroliz koşullarında hızlı pirolizi gerçekleştirilmiştir. Hızlı piroliz çalışmaları, borusal reaktörde sürükleyici gaz ortamında iki farklı grupta ...
