Investigation of suitable digestion methods for the determination of total phosphorus in soils
(Elsevier Science Bv, 1997)Total phosphorus in five soils with different compositions which were obtained from different places were extracted by using Na2CO3 fusion, HClO4 digestion, HClO4 + HNO3 digestion, HF + HClO4 digestion or NaOBr oxidation ... -
Electrokinetic properties of perlite
(Academic Press Inc Jnl-Comp Subscriptions, 1997)Electrokinetic properties of expanded and unexpanded perlite samples have been investigated using the microelectrophoresis technique. Perlite samples yield practically no isoelectric point in the pH range of 3 to II. Both ... -
Thermal behaviour of some metal complexes of N,N-diethyl-N'-benzoyl thiourea
(John Wiley & Sons Ltd, 1997)The thermal behaviour of the complexes of N,N-diethyl-N'-benzoylthiourea (DEBT) with NI(II), Cu(II), Pt(II), Pd(II) and Ru(III) was studied using differential thermal analysis (DTA) and thermogravimetry (TG). These complexes ... -
Essential oils of calamintha pamphylica boiss. et Heldr. subsp. pamphylica and subsp. davisii (Quezel et Contandr.) Davis
(1997)Water-distilled essential oils of two subspecies of Calamintha pamphylica namely, subsp. pamphylica and subsp. davisii, both of which are endemic taxa to Turkey, were analyzed by GC and GC/MS. In the oil of subsp. pamphylica ... -
A tunable hot-electron light emitter
(IOP Publishing LTD, 1997)We demonstrate the operation of a novel tunable wavelength surface emitting device. The device is based on a p-GaAs and n-Ga1-xAlxAs heterojunction containing an inversion layer on the p-side, and GaAs quantum wells on the ... -
Monte Carlo calculations of medium energy positrons in metals
(Pergamon-Elsevier Science Ltd, 1997)The Monte Carlo code, which has been used previously to simulate the transport of positrons in aluminium and copper, was modified for simulating the positron transport in silver, tin, gold and lead with incident positron ... -
