The growth of cities and population growth has changed the structure and imbalance between the body of the city and nature, and increasing the need for public places to pass and acquire comfort. Parks were created in order to balance the urban and nature. But with the passage of time and thriving places; Parks, to the place of crime, also made it difficult to use for all strata. The purpose of this paper is to assess and measure the security factors of women in urban parks with emphasis on environmental security (studied by Allameh Ahvaz); According to the nature of the subject and goals for which predicted, descriptive-analytical type; The statistical population of women in Allameh park, which was selected, were selected randomly. Data analysis was performed using SPSS software and Friedman's correlation test, Kurkal Wallis Ht-test. Findings indicate that the ranking of social and security variables based on Friedman test shows that the presence of people at different hours of day with an average of 13\/6, ranked first, communicating with the park with an average of 32\/5, ranked Second, the permeability of motor vehicles, security in the commute with an average of 4.79 in the third place.

Social monitoring, comfort and comfort and socialization, etc. directly affects the desirability of public spaces from the perspective of women, which utilizes this issue and modify and modify any of these independent variables in space Urban can provide adsorbent environments for the presence of all users and especially women.

Study the effect of silisum spray in rosa flowers, experiment in a completely randomized design with 7 treatments included 3 replications and each replications with 3 pots were conducted. Treatments include sodium silicate, calcium silicate and potassium silicate, each with two levels of 25 and 50 ppm and the pot was considered as control without spraying. Pots, two times in the first week of spraying was conducted on the same basis and traits such as petals antocyanin, leaf total chlorophyll, phenyl alanin amonialyase activity and flowers longevity on plant were evaluated. The results showed that the treatment of CaSi 50 ppm had the greatest effect on correction the traits. Result at 1% statistical level had significant effect.

In this paper vertically aligned Multi-walled carbon nanotubes (VA-MWCNTs) have been successfully synthesized by chemical vapor deposition (CVD) using ethanol (C2H5OH) as a carbon source and Co as a catalyst on quartz substrate. The effects of growth time and growth temperature on MWCNT growth were studied in detail. At 45 min growth time, by increasing the growth temperature from 550 oC to 650 oC, the length and density of MWCNTs increase. At 750 oC, MWCNTs become spaghetti-like. The optimum growth conditions were found to be at growth temperature of 650 oC. At 650 oC, by increasing the growth time from 30 min to 75 min, the length of carbon nanotubes increases (from 2μm to 12μm approximately). The morphology and structure of the grown MWCNTs were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Raman spectroscopy techniques.

For study the effect of silisum spray in rosa flowers, experiment in a completely randomized design with 7 treatments included 3 replications and each replications with 3 pots were conducted. Treatments include sodium silicate, calcium silicate and potassium silicate, each with two levels of 25 and 50 ppm and the pot was considered as control without spraying. Pots, two times in the first week of spraying was conducted on the same basis. Morphological traits such as flower fresh weight, flower dry weight, flower diameter, stem diameter and flowers stem lenght were evaluated. The results showed that the treatment of CaSi 50 ppm had the greatest effect on correction the traits. Result at 1% statistical level had significant effect.
