1. PLANTS OF HASHILAN WETLAND, KERMANSHAH, IRAN
Volume 12, Issue 3 , Summer 2001

Abstract
  Plants of Hashilan, a 260 ha freshwater wetland, located at 35 km northwest of Kermanshah, the provincial capital of Kermanshah Province, western Iran, were studied. Altogether, 116 species of plants (77 terrestrial and 39 aquatic) representing 96 genera and 42 families were identified. Asteraceae with ...  Read More

2. BIOOXIDATION OF MOUTEH REFRACTORY GOLD-BEARING CONCENTRATE BY AN ADAPTED THIOBACILLUS FERROOXIDANS
Volume 12, Issue 3 , Summer 2001

Abstract
  The Mouteh refractory pyrite concentrates at pulp densities of 1.5%, 3%, 4.5% and 6% were treated, using Thiobacillus ferrooxidans DSM 581 and the same bacteria adapted on the Mouteh pyritic concentrate. Compared with a non-adapted culture, use of an adapted inoculum of T. ferrooxidans increased bioleaching ...  Read More

3. CYTOGENETICAL STUDY IN SOME ALFALFA CULTIVARS OF IRAN
Volume 12, Issue 3 , Summer 2001

Abstract
  A cytogenetical study on 13 alfalfa (Medicago sativa) cultivars available in Iranian Forest and Rangelands Genebank was performed in order to obtain basic information on the variability in chiasma frequency/distribution, chromosome association and segregation. Such cytogenetic information is useful for ...  Read More

4. STUDY ON SORPTION OF SOME TOXIC AND HEAVY IONS IN DILUTE SOLUTIONS BY CLINOPTILOLITE
Volume 12, Issue 3 , Summer 2001

Abstract
  The deposits of clinoptilolite (CLI) in Iran after activation with sodium chloride or sodium hydroxide solution was subjected to ion exchange with some heavy and toxic cations. The results showed that the absorption for Ca2+ (7.5 ppm), Cu2+ (50 ppm), Zn2+ (40 ppm), Cd2+ (40 ppm), Pb2+ (500 ppm) and ...  Read More

5. SYNTHESIS OF AZINES FROM CARBONYL COMPOUNDS IN A SOLVENT-FREE CONDITION
Volume 12, Issue 3 , Summer 2001

Abstract
  In an environmentally benign solventless system, aldehydes and ketones were readily converted to their corresponding azines with hydrazine sulfate, sodium hydroxide and alumina in high yield.  Read More

6. A NEW STRATEGY FOR THE SYNTHESIS OF TRICYCLIC AND TETRACYCLIC SYSTEMS OF INDOLE ALKALOIDS
Volume 12, Issue 3 , Summer 2001

Abstract
  Reaction of tryptamine 1 with dimethyl -3-methoxyallylidenemalonate 2 afforded N?-[4,4-bis (methoxycarbonyl)-1,3-butadienyl] tryptamine 3 which in combination with acetylchloride and pyridine in dichloromethane gave N?, N?-[acetyl]-[(4,4-dinethoxycarbonyl) 1,3butadienyl] tryptamine 4. Treatment of 3 ...  Read More

8. GENERAL SYNCHRONIZATION OF COUPLED PAIR OF CHAOTIC ONE-DIMENSIONAL GAUSSIAN MAPS
Volume 12, Issue 3 , Summer 2001

Abstract
  In this paper we review some recent ideas of synchronization theory. We apply this theory to study the different synchronization aspects of uni-directionally coupled pair of chaotic one-dimensional Gaussian maps.  Read More

9. TESTING FOR AUTOCORRELATION IN UNEQUALLY REPLICATED FUNCTIONAL MEASUREMENT ERROR MODELS
Volume 12, Issue 3 , Summer 2001

Abstract
  In the ordinary linear models, regressing the residuals against lagged values has been suggested as an approach to test the hypothesis of zero autocorrelation among residuals. In this paper we extend these results to the both equally and unequally replicated functionally measurement error models. We ...  Read More

10. COMPARISON OF DIFFERENT GLASS COMPOUNDS FOR INTRINSIC FIBER OPTIC TEMPERATURE SENSORS
Volume 12, Issue 3 , Summer 2001

Abstract
  Different glasses suitable for temperature sensing in the fiber optic sensors were studied in this article. The phase changes for eight different glass materials were calculated and results were compared. Our results showed that extra dense flint glass is the most sensitive one, while pure silica results ...  Read More

11. SADDLE POINT VARIATIONAL METHOD FOR DIRAC CONFINEMENT
Volume 12, Issue 3 , Summer 2001

Abstract
  A saddle point variational (SPV ) method was applied to the Dirac equation as an example of a fully relativistic equation with both negative and positive energy solutions. The effect of the negative energy states was mitigated by maximizing the energy with respect to a relevant parameter while at the ...  Read More
