Influence of Matric Potential on Survival and Activity of Genetically Engineered Ralstonia eutropha H850Lr
Although the application of biodegradative genetically engineered micro organisms (GEMs) for bioremediation is very promising, the risks of their release should be assessed before their introduction into the environment. Lux-marked Ralstonia eutropha H850Lr (formerly Alcaligenes eutrophus H850Lr) was introduced into sterile and non-sterile soil microcosms at matric potentials ?2.11, ?30, ?750, and ?1500 kPa. Viable cell concentration and luminescence activity of R. eutropha H850Lr was measured by plate counting and luminometry respectively. R. eutropha H850Lr could survive better in non-sterile soil at ?30 kPa than other matric potentials. Luminescence values were closely related to viable cell concentrations indicating the usefulness of a Bioluminescence-marker system for tracking the above bacterium in the environment. Statistical analysis showed a significant effect of matric potential on viable cell concentrations. The luminescence activities in the soil environment emphasize that these factors should be considered during application of GEMs in the natural environment.

A Preliminary Study on the Molecular Identification of Herpes Simplex Virus Type 1 in Iranian Population
Herpes Simplex Virus Type 1 (HSV-1) is a member of the Herpesviridae family that causes herpetic disease in human. During the last 25-30 years, many investigations have been conducted on pathogenesis and molecular biology of this virus in several countries. In Iran HSV-1 has been isolated from patients and detected using immunological techniques. In this study, we investigated the molecular aspects of two Iranian isolated viruses by PCR-RFLP of HSV-1 DNA Polymerase gene. The result of Southern blot hybridization indicated that the Iranian isolates are HSV type 1. Moreover, the restriction pattern of the Iranian isolates is different from the KOS strain for DpnI enzyme. It is proposed to use this difference as a molecular marker of the Iranian strain.

Synthesis of some New Imidazolones and 1,2,4-Triazoles Bearing Benzo[b]thiophene Nucleus as Antimicrobial Agents
2-Phenyl-1-(3?,5?-dichloro-2?-benzo(b)thiophenoylamino)-4-arylidine-5-imidazolones (2a-j) were prepared from the 2-hydrazinocarbonyl-3,5-dichlorobenzo[b]thiophene 1 by the reaction with different oxazolinone which were prepared by the condensation of substituted benzaldehyde with benzoyl glycine in presence of sodium acetate and acetic anhydride. Reaction of 1 with different aromatic isothiocyanate afforded the corresponding N1-(3?,5?-dichlorobenzo[b]thiophen-2?-yl)-N4-substituted aryl thiosemicarbazides (3a-j). Compounds (3a-j) on reaction with sodium hydroxide yielded 3-(3?,5?-dichlorobenzo[b]thiophen-2?-yl)-4-aryl-5-mercapto-1,2,4-triazoles (4a-j). The pharmacological evaluations were performed for their antitubercular and antimicrobial activities. Some novel imidazolones and 1,2,4-triazoles were synthesized and evaluated for in vitro antibacterial activity against Escherichia coli ATCC 25922, Proteus vulgaris ATCC 6380, Bacillus megaterium ATCC 14581, Staphylococcus aureus ATCC 29213, and antifungal activity against Aspergillus niger ATCC 9029. The in vitro antimycobacterial activity of the new compounds was also investigated against Mycobacterium tuberculosis H37RV (ATCC 27294) in BACTEC 12B medium using the ALAMAR radiometric system. The structures of new compounds were supported by IR, 1H-NMR and Mass spectral data.

Syntheses of Substituted 1,3,4-Oxadiazole, 1,3,4-Thiadiazole and 1,2,4-Triazole Derivatives as Potential Antimicrobial Agents
A series of 2-(4-nitro-1-imidazolylmethyl)-1,3,4-oxadiazole, 1,3,4-triazole and 3-(4-nitro-1-imidazolylmethyl)-1,2,4-triazole derivatives were synthesized and tested for their antimicrobial activity. Some of the tested compounds were active against Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, Clostridium difficile, Aspergillus niger and Cryptococcus neoformans.

S-C-O Isotopes, Fluid Inclusion Microthermometry, and the Genesis of Ore Bearing Fluids at Qaleh-Zari Fe-Oxide Cu-Au-Ag Mine, Iran
Qaleh-Zari is a Fe-oxide Cu-Ag-Au vein type deposit located 180 km south of Birjand, in eastern Iran. Host rocks are mainly Tertiary calc-alkaline to K-rich calc-alkaline with transition to shoshonitic andesite and andesitic basalts, but in the central part shale and sandstone of Jurassic age. Andesitic rocks from the western region of Qaleh-Zari were dated to 40.5 ± 2 Ma. Four trends of faults and joints are identified in the mine area. Cu-Ag-Au mineralization is present only in the oldest sets of faults and joints that crosscut the Tertiary and Jurassic units. Three major sub-parallel steep quartz veins are identified. No.1 vein is about 650 m long and No.3 vein is less than 500 m long. No.2 vein is traced for more than 3.5 km horizontally along strike (N40° W) and more than 350 m down dip. Specularite and quartz are the most abundant primary oxides. Chalcopyrite is the only hypogene copper mineral. Silver is present as sulfosalt minerals. Paragenesis: Stage I: specularite, quartz, Fe-chlorite, chalcopyrite and sulfosalts. Specularite deposited first and forms 10 to 25 percent of the vein. Stage II: quartz, chalcopyrite, pyrite, chlorite ± hematite ± sulfosalt minerals. Stage III: quartz ± pyrite ± chalcopyrite. Stage IV: hematite, quartz, and ± calcite. The ores grade typically 2-9% Cu, 100-650 ppm Ag, and 0.5-35 ppm Au. Homogenization temperatures of fluid inclusions associated with Cu, Ag, and Au deposition were varying between 360°C and 240°C. The salinity of the fluid was between 1 to 6 wt % NaCl equiv and the CO2 content was low (less than 1 mole %). The ?34SCDT values of pyrite and chalcopyrite were between 0.4 to 2.2‰, which was consistent with a magmatic-hydrothermal or leached volcanic source. The ?13CPDB values of calcite were between 16.9 to 17.4‰ and the calculated ?13CPDB of the fluid is between ?3.8 and ?3.0‰. The ?18OSMOW of the carbonates were between 16.96 and 19.40‰. Calculated fluid ?18OSMOW values were 7.4 to 9.8‰, which overlapped the range of magmatic water. The C and O isotopic values of calcite were similar to porphyry copper deposits, possibly indicating magmatic affinities for the ore fluids. Based on the presence of hematite, chalcopyrite, Fe-rich chlorite and locally pyrite, and on the absence of magnetite and pyrrhotite, the ore fluid was very oxidized. Oxygen fugacity was estimated to have been between 10?27 and 10?32, and the fugacity of H2S was less than 10?3.5.

Parallel Generation of t-ary Trees
A parallel algorithm for generating t-ary tree sequences in reverse B-order is presented. The algorithm generates t-ary trees by 0-1 sequences, and each 0-1 sequences is generated in constant average time O(1). The algorithm is executed on a CREW SM SIMD model, and is adaptive and cost-optimal. Prior to the discussion of the parallel algorithm a new sequential generation with O(1) average time complexity, and ranking and unranking algorithms with O(t n) time complexity is also given.

Study of Iridium (Ir) Thin Films Deposited on to SiO2 Substrates
Very smooth thin films of iridium have been deposited on super polished fused silica (SiO2) substrates using dc magnetron sputtering in argon plasma. The influence of deposition process parameters on film micro roughness has been investigated. In addition, film optical constants have been determined using variable angle spectroscopic ellipsometery, over the spectra range from vacuum ultraviolet to middle infrared (140 nm-35 ?m). Also the surface roughnesses were measured by atomic force microscopy (AFM).
