Aims The complexity of today`s urban issues are such that researchers and urban designers can not manage to to focus on all topics simultaneously and explain the consequences of their decisions and their designs in urban spaces. Space syntax logic, which is one of the mechanisms that can help in overcoming these types of problems, uses software that has high accuracy in mathematical calculations and presentation of graphic maps. The purpose of this research is to investigate the qualities of the spatial dimension and the experience of pedestrians in Resalat Square, Tehran.

Methodes in this study, while using DepthMap software due to observations and interviews with residents, retailers and pedestrians and observing the problems of citizens' access to different parts of the square, the technical weaknesses of software related to space syntax logic were identified and the strengths and weaknesses were achieved through SWOT technique.

Findings After reviewing the preliminary results and observing the methodological contradictions, the field survey was renewed inorder to reveal the additional requirements. The results can be considered in two aspects. Firstly, raising additional awareness to refine space syntax logic, mathematical cognition, and DepthMap software, and secondly, achieving comprehensive cognition of Resalat Square in spatial structure.

Conclusion The human experience of the city can be different from the quantitative results obtained. The final results indicate that the south and southwest areas of Resalat Square have the best state of integration and connection with other urban spaces and consequently have the greatest potential for development.

The flavonoid and phenolic compounds are among the main pharmaceutical components of medicinal plants. These compounds are considered as effective anti-oxidant sources. Five cyanobacterial extracts were used to stimulate the plant growth and increase production of specific secondary metabolites in Plantago major as a medicinal plant. These cyanobacteria were isolated from the growth bed of the plant in its natural habitats. Nitrate-free BG11 medium was used for preparing axenic monoalgal cultures. Pot experiments were performed by spraying cyanobacterial extracts on the soil of treated plants every 20 days from the time of planting. Growth of plants was evaluated by measuring growth parameters such as plant height, root length, dry and fresh weight of plant, leaf number, leaf area, as well as inflorescence characteristics 60 days after planting. In addition to growth factors, the total amount of phenol and flavonoid of plants was also assessed. Statistical analysis showed that there was a significant difference in the vegetative and reproductive characteristics compared to the control plants. Also, the methanolic extraction of treated and control plants displayed the highest total phenolic and flavonoid content 77.23±3.21 µg of GA mg^-1 and 389.67±34.43 µg of RU mg^-1 in plants treated with Cylindrospermum michailovskoence. Based on the obtained results, cyanobacterial fertilizers are suggested as the biological elicitors to improve the quantity and quality of medicinal plants products. As a result of this study, chemical content of cyanobacterial extracts and the production of plant growth stimulating substances such as phytohormones can be proposed as factors affecting plant growth parameters and metabolites production.
