In the present study, an efficient protocol has been developed for callus induction and production of RA in callus culture of Satureja khuzistanica for the first time. In vitro callus induction was achieved from young shoot tip explants cultured on MS and B5 media supplemented with different concentrations of IBA (0.1, 1.0, 2.0 and 5.0 mgl-1) solely or in combination with cytokinins BAP and KIN...

in this study chitosan hydrogel beads with porosity ~ 0.86 and diameter ~ 20.07 mm were prepared from 85 % deacetylated chitosan for removal of cd2+ ions from aqueous solutions.  chitosan powder was dissolved into dilute acetic acid as solvent and formed into spherical beads using a phase inversion technique. the effect of temperature, initial concentration of cd2+ ions, and the period of agita...

in this study, rainbow trout (oncorhynchus mykiss) eggs were treated with effective doses of  daenensis thyme, thymus daenensis (20, 10 and 5 mgl-1) and mentha, mentha longifolia (10, 5 and 2.5 mgl-1), during incubation period (20 days) until hatching for 30 minutes per every other day as constant flow bath treatment method. the mortality level in normal control (without any treatment) was sign...

Synthetic nitrogen fertilizers can contribute to environmental hazards. Moreover, their manufacturing is an energy-intensive process which causes greenhouse gas emissions, lead climate change. Therefore, it should evaluate the possibility use organic sources such as Azolla a partial substitute for synthetic in cultivation, this may reduce cost of fertilizer inputs, and promote sustainable agric...

The distribution of microbial communities in the Menggulin (MGL) and Ba19 blocks in the Huabei Oilfield, China, were studied based on 16S rRNA gene analysis. The dominant microbes showed obvious block-specific characteristics, and the two blocks had substantially different bacterial and archaeal communities. In the moderate-temperature MGL block, the bacteria were mainly Epsilonproteobacteria a...

We analyze the surface plasmons (SPs) propagating along optically pumped single-graphene layer (SGL) and multiple-graphene layer (MGL) structures. It is shown that at sufficiently strong optical pumping when the real part of the dynamic conductivity of SGL and MGL structures becomes negative in the terahertz (THz) range of frequencies due to the interband population inversion, the damping of th...

Bioremediation of phenol was done using Candida tropicalis SSK01 immobilized cells isolated from petroleum contaminated soil. Optimization of phenol degradation studies was carried at 30 °C to 40 °C, pH 6 to 8 and initial concentration of 300 mgl⁻¹ to 900 mgl⁻¹. Candida tropicalis SSK01 cells immobilized using sodium alginate were used in phenol degradation studies. Optimization of phenol degra...

Introduction: 2013 marks the 25 anniversary of the NASA Planetary Science Summer School (PSSS) [1], which is held every summer at the NASA Jet Propulsion Laboratory to provide postdocs and Ph.D. students with an intensive interdisciplinary experience in planetary robotic mission design under the tutelage of JPL's Advanced Projects Design Team ("Team X") [2]. This abstract summarizes the work of...
