The present research was conducted with the purpose of presenting the model of using mentoring (development of communication skills, education, etc.) in personal development.

The statistical community in the qualitative part of the research included Tehran municipality experts, 20 of whom were considered as the sample size using the saturation principle. In the quantitative part, it included all the executive managers of Tehran municipality, 225 of whom were selected as the research sample. The method of data analysis was used in the qualitative part of theoretical coding and in the quantitative, descriptive and inferential part (tests such as Pearson correlation, confirmatory factor analysis) using SPSS-v21, Smart Pls-v2 and Lisrel-v8 software.

The results of the research showed that among the 84 indicators (items) available, 15 main components can be identified. The components of development of inherent skills, development of technical skills, development of communication skills, development of environmental skills were identified as the components of using mentoring in personal development, and the components of innovative performance, sustainable competitive advantage and educational quality were identified and introduced as effective factors on the use of mentoring in personal development. Were placed.

managerial, technological and educational factors were identified as strategies, environmental, democratic and educational factors as facilitators and technological and educational factors as existing obstacles. Finally, a model was presented that had a good fit.

Nickel (Ni) is an element which has been added recently to the list of necessary micronutrients for plants. But, as a heavy metal, especially at high concentrations, it causes oxidative stress in plants. Knowledge of physiological and biochemical responses of plants to Ni stress can help to understand the mechanisms of adaptability. The effects of Ni on chlorophyll content, proline, soluble proteins and protein electrophoresis pattern were investigated in 40 day-old Coronilla Varia plants grown in hydroponic condition in Hoagland solution that was treated with 0, 2.5, 5, 7.5 and 10 mM NiCl2. After 24 and 72 hours, the chlorophyll content, proline, soluble proteins and protein electrophoresis pattern of leaves were measured. Results revealed that chlorophyll a, b and total chlorophyll content of leaves declined progressively under Ni stress at both times. But this change was more sensible after 72 hours. A significant increase of proline content was detected in leaves after 24 and 72 hours exposure to Ni. In general, increase of proline content was more pronounced in shorter exposures to Ni, which could be due to the adaptation of plants to Ni stress in longer durations. The soluble protein content of leaves was reduced significantly with increasing Ni stress. Protein electrophoresis pattern was changed in Ni treatments; at higher Ni concentrations, the 72 and 250 k Dalton bands disappeared and 95 and 130 k Dalton bands were appeared. The results of this research discuss the contradictory effects of Ni on accumulation of chlorophyll and protein content with respect to proline.

In this study, the effects of Ni and Zn to leaf anatomy, some flavonoids and nitrotoxin of Coronilla varia were investigated. 40 days aged grown Coronilla varia L. plants in equal growth condition were treated with different concentration of ZnCl2 (0, 7.5, 15, 22.5 and 30 mM) and NiCl2 (0, 2.5, 5, 7.5 and 10 mM) for 24 and 72 hours in hydroponic culture and the effects of imposing heavy metals on Leaf anatomy, some flavonoids of control and treated plants examined and compared using 2-DPC (Two Dimensional Paper Chromatography) and TLC (Thin Layer Chromatography) methods. Nitrotoxin measured using spectrophotometer too. All of Data compared together. Results showed anatomical changes in polluted plants responses to Zn and Ni. In general results showed a wide changes in leaf flavonoids profile with increases number of total flavonoids at Zn and Ni stress. However, Nitrotoxin increased significantly when Zn and Ni increased. Probably, C. varia L. can tolerate against heavy metals stress of Zn and Ni with changes of flavonoids content and nitrotoxin.
