Like other people with disabilities are entitled to the comfort of roads, streets, offices and banks in this regard with the problem and hinder traffic and do not. Failure to comply with appropriate legislation and remove architectural barriers at the level of problems for people with disabilities, veterans, people with disabilities, the elderly and .... Buildup. The purpose of this study was to create flexible urban streets and in accordance with the wishes and needs of the disabled. Cochran method is used. And randomly assigned 384 people with disabilities and 164 officials were evaluated. To collect data, a questionnaire was used. And data analysis, was done with SPSS software. The findings showed that in Region 2 and 10 of Tehran has been partially consistent with the standards. And if the implementation rules and regulations tailored to the needs of the disabled community, the movement of other people will improve.  In the current situation for lower share of the disabled population of the total population in the census; Lack of sufficient financial resources of municipalities, And a lack of understanding of the necessity of implementing rules and regulations tailored to the needs of the disabled community by the relevant authorities is the most important reasons the lack of compliance passages tailored to the needs of persons with disabilities.

Different types of soil erosion including gully erosion occur in many parts of Iran. The west of Iran is further threatened by gully erosion due to its specific physical and climatic conditions. However, few studies have been carried out to study the sediment production of gully erosion in Iran. This research was therefore conducted to measure storm-wise sediment production of gully erosion in the west of Iran. To achieve the study objectives, 48 gullies located in three small watersheds viz. Darreh-Shahr, Abbas-Abad and Hollowsh in Ilam and Lorestan Provinces were monitored. The volumes of gullies were measured before and after 5 rainstorms for Darreh-Shahr and Abbas Abad watersheds and 6 rainstorms for Hollowsh watershed from 2005 to 2007. Sediment production was calculated on storm basis for each gully. The results revealed that the minimum and maximum volumes of gully erosion were 0.002 and 1.010 m³, respectively, for one millimeter of rainfall. The results indicated that soil moisture, percentage of silt and clay, amount and intensity of rainfall and drainage area were the most important factors on formation and sediment production of gully erosion.

Understanding the development of gully volumes requires the empirical relations between gully volume (V) and length (L) to be established in the field. So far, such V–L relations have been proposed for a limited number of gullies/environments and were especially developed for ephemeral gullies.In this study, V–L relations were established for ephemeral gullies in southern Ilam. In order to take the regional variability in environmental characteristics into account, controlling factors of gully cross-sectional morphology were studied for 90 cross-sections. The results indicated that the soil properties were the most important controls of gully cross-sectional shape and size. Cross-sectional size could be fairly well predicted by their drainage area. The V–L relationship for the complete dataset was V=15.45 L ^0.12 (n = 90, R²=0.06). In addition, gully volume was also related to its catchments area (A) and catchment slope gradient (S_c). This study demonstrated that the V–L and V–A×Sc relations were not suitable to assess ephemeral gully volume.

Aim: Caspian locust, native to Hyrcanian forests of Iran, is one of the pioneer species, which it distributed in the moist soils of these forests. So far, the response of its seedlings to permanent and temporary flooded beds has not been reported. This study was conducted with the objective to analyze the physiological responses of Caspian locust seedlings to flooding and flooding-recovery conditions.

Materials & Methods: Flooding conditions were examined for 90 days in the greenhouse of the Tarbiat Modares University. The study was carried out in a factorial experiment as a completely randomized design with 5 treatments and 4 replications. Treatments included: (1) continuous flooding for 90 days (F90), (2) flooding for 60 days followed by a 30-day recovery (F60+R30), (3) flooding for 45 days followed by a 45-day recovery (F45+R45), (4) flooding for 30 days followed by a 60-day recovery (F30+R60) and (5) Control.
Findings: Results showed that flooding for 90 days induced a significant decrease in net photosynthesis (-91%), stomatal conductance (-77%), transpiration (-81%), Chl a (-63%), Chl b (-67%) and Chl _Tot (-64%) compared to the control (p<0.05). When flooding was removed for 30-60 days, plants were able to recover gas exchange activities from 30 to 90% and Chl content by 55-90%.
Conclusion: Based on our results, seedlings of G. caspica can survive and grow throughout a medium period of soil waterlogging. Therefore, Caspian locust appears to be a promising species for reforestation programs in the riverine areas and temporarily flooded wetlands.

The response surface methodology was used to produce cherry jam containing stevia sweetener with desirable physicochemical, sensory and rheological properties. These experiments were planned using a central composite design (CCD) with three independent variables including sugar, pectin and stevia. The production process of samples was done in five levels of sucrose (50-10%), pectin (0.5-1%) and stevia (0.6-0.2%) in a constant amount of 300 g of fruit. To evaluate the jam, the physicochemical, sensory and rheological properties of the jam were determined and optimized. Concentrations of sucrose, pectin and stevia had a significant effect on the color, sensory and rheological properties of the jam. The results showed that none of the linear and interaction effects of the studied factors on the pH of cherry jam were significant. The values ​​of L * (brightness) and b * (yellowness) increased with increasing concentrations of sucrose and stevia, also increasing pectin increased a * (redness) of the jam. The evaluation results of sensory tests showed that the sugar variable plays an important role in improving the sensory parameters of the jam. Examination of the tests resulting from the creep test showed that the sugar factor plays an important role in the value of the parameters G0 and η0. The results show that the viscosity shown by Dashpot Maxwell (η0) can be a good indicator of the effect of sucrose concentration in the jam. Also, G1 and η1 parameters can not be clear indicators for understanding the structural changes in the jam with changes in the concentration of sugar, pectin and stevia. In general, the results of the study showed that using pectin and stevia sweetener can reduce the amount of sucrose in the jam and produce a low-calorie product with optimal quality and desirability index of 0.69 on a commercial scale.

Cheese is one of the most consumed milk products. At present, one of the most widely used salty white cheeses in Iran is the cheese produced by the ultrafiltration method. Non-thermal (cold) plasma is a new method to remove food microorganisms. In this research, the effect of cold plasma on the reduction of microbial load and qualitative and rheological characteristics of cheese samples produced through different tests was investigated. The samples were prepared and produced in Pegah Hamadan Company under two microbial treatments (yeast mold and coliform) and the duration of plasma application at two levels (7 and 13 minutes) and the control sample (lack of contamination, no plasma) and during the storage period of 30 days. They were tested once every ten days with 2 repetitions by colorimetric tests, pH, and tissue test (TPA) and Warner test. The results of the statistical analysis of the obtained data showed a significant difference in the evaluated traits between the control sample and the treatments that underwent the cold plasma process. The value of parameter L* in the samples treated with cold plasma decreased compared to the control sample, also the index b* (yellowness index) did not increase significantly for all cheese samples at the end of the storage period. There was no significant difference in the amount of Springiness between the samples treated with plasma and the control sample, and the amount of gumminess did not increase significantly during the storage period. There was a significant increase in shear modulus, shear stress and shear force between the first day and the 10th, 20th, and 30th days. It can also be concluded that the treatments with coliform contamination have less stiffness and strength than other treatments and the type pollution added to the samples is the cause of this significant difference.
