Separate or combined effects of inulin and mannan oligosaccharide supplements on the growth, survival, body composition and salinity resistance of kutum roach (Rutilus frisii kutum) fry (410 ± 19 mg)  were investigated for 45 days in 40-liter tanks containing 30 individuals. Fish were fed 7 to 12% body weight with a commercial diet (35% protein and 12% lipid) supplemented with 0 (control), 5 g kg^-1 inulin, 5 g kg^-1 MOS and 2.5 g kg^-1 inulin + 2.5 g kg^-1 MOS in a totally randomized design trial in triplicate.  A general enhanced growth performance and feed efficiency were observed in fish fed on diet containing 5 g kg^-1 MOS (p<0.05). There were no significant differences in survival rate among treatments (p>0.05). NO significant difference was observed in body composition, but protein and lipid contents in the whole body increased in fish fed with 5 g kg^-1 MOS and control group. In general, the fish fed 5 g kg^-1 MOS had the highest survival index after 48 hours exposed to salinity stress (15 ppt). Results showed 5 g kg^-1 MOS could improve growth performance, survival and salinity stress resistance of kutum fry.

Problem:Urban public spaces, especially parks, are vital places for families.However, until now,less emphasis has been placed on articulating spatial quality indicators for all ages,and the environmental requirements for different groups of all age are rarely integrated.
Aims:This research aims to discover indicators from the perspective of urban space for all ages in parks and provide a tool for advancing towards lifelong communities and at a higher level to improve the quality of public space.
Methods:The research method in this study is applied and It employs descriptive-analytical method. In the present study, one dependent variable titled and 12 independent variables have been introduced in Mellat Park in Qazvin as a case study.
Findings:we found that "comfort" and "social participation and encouragement of intergenerational relationships" have the greatest impact,while "security" and "sensory richness and creativity in design" have the least impact on explaining the dependent variable.indicators such as "safety" and "sensory richness and creativity in design" are more significant for younger ages, whereas indicators such as "security" and "respect for diversity and differences of all ages with any level of ability" are more significant for older ages, making them some of the most influential factors in determining the quality of Mellat Park in Qazvin.
Conclusion:Based on the research findings,it can be concluded that Mellat Qazvin Park is not yet suitable for all ages.The differing priorities of indicators for various age groups suggest that achieving an average across all indicators could make the park more inclusive for everyone.

The combined effects of two major contributing factors, i.e. inertial soil-structure interaction (SSI) and near-fault ground motions, on structural responses were studied. Considering nearfault characteristics, soil-structure systems are subjected to both actual near-fault ground motion records and their dominant kinematic characteristics, i.e. forward rupture-directivity pulses, coherently travelling waves seen as a large amplitude and short duration pulse-type motion at the beginning of each fault-normal component of the record. As a result of the suitability of forward rupture-directivity pulses for quantifying the salient response features of structures, a mathematical model, proposed by Makris, was used to represent the forward rupture-directivity pulse-type motions. Using a comprehensive parametric study, the structure, a bilinear single degree of freedom (SDOF) system, the soil beneath the structure and a homogeneous elastic half-space were combined based on a discrete model to constitute the overall soil-structure model. The results have been presented in the form of elastic strength demand graphs for a wide range of non-dimensional key parameters, which describe the SSI effects. Both the soil-structure systems and the corresponding fixed-base structures were considered and compared. Using numerical time-stepping analyses, it was found that the response of soil-structure systems subjected to actual near-fault records is similar to those subjected to forward rupture-directivity pulses. Consequently, the forward rupture-directivity pulses can be used to predict the salient response features of soil-structure systems in seismically active regions. They can also be a realistic representation of near-fault ground motions for predicting the response of long-period structures. It was further observed that quite interestingly, the response of soil-structure systems subjected to actual near-fault records, has two maximum regions. However, it was recognized that further study would be required to clarify these regions. The results also indicated that considering SSI is critical for a variety of structures. Accordingly, underestimated near-fault responses could be obtained when the SSI effects are ignored.

Abstract The main objective of this research was to investigate mechanisms to reduce agricultural waste applying the views of specialists of the field. This research was an applied research with a quantitative nature. The data were collected in a descriptive survey method and it has been designed using Delphi method to attain group agreement. The panel of expert members in the research has been all specialists in the field of agricultural waste management in three academic levels, administrative organizations and research organizations among which 18 expert and experienced specialists were selected through the purposeful chain sampling method to answer the research main questions. The main data-collecting tool was a structural questionnaire. Based on the results of the research, the specialists agreed on 48 mechanisms to reduce agricultural waste that were classified into seven factors including infrastructure - social, economical, policy making - planning, productive – production, technical,– extension- education and research.
