Sediment transport is a complex phenomenon due to the nonlinearity and uncertainties of the *** present study applies Gene Expression Programming（GEP） to develop bedload transport models in sewer pipes. In this regard, two types of bedload were considered: loose bed（deposition state） and rigid bed（limit of deposition state）. In order to develop the models, two scenarios with different input combinations were considered: Scenario 1 considers only hydraulic characteristics and Scenario 2 considers both hydraulic and sediment characteristics as inputs for modeling bedload discharge. The results proved the capability of GEP in prediction of sediment transport and it was found that for prediction of bedload transport in sewer pipes Scenario 2 performed more successfully than Scenario 1. According to the outcome of sensitivity analysis, Frm（Modified Froude number） and d50/y（relative particle size） for rigid boundary and Frmfor loose boundary had key roles in the modeling. The outcome of the GEP models also was compared with existing empirical equations and it was found the GEP models yielded better results. It was also found that pipe diameter affected the transport capacity of the sewer pipe. Increasing pipe diameter caused an increase in model efficiency. A pipe with a diameter of 305 mm yielded to the best results.

In this paper, remote sensing techniques,as well as field studies, have been used to investigate the geomorphological processes and landscape evolution along the Saravan Fault, SE Iran to highlight how topographic features were influenced by active tectonics. Quantitative geomorphic analysis was carried out using mountain-front sinuosity(Smf),valley floor width-valley height ratio(Vf), drainage basin asymmetry factor(Af), Hypsometric integral(Hi), drainage basin shape index(Bs), mean axial slope of channel(MASC), standard deviation of topography(STD) and index of active tectonic(Iat).Remote sensing techniques, as well as field studies revealed that the Saravan Fault have three parts trending N-S, NW-SE, and E-W. Obtained results show that basins with high Iat index are located at where the strike of the Saravan Faults changes and where several strike-slip faults are crossed the Saravan fault.

Objective: The effort–reward imbalance(ERI) model claims that work that has the characteristics of high effort and low reward has a mutual defect between input and output and this imbalance may result in sustained and long-lasting results. This study aimed to investigate the relationship between the intention to leave the profession(ILP) and ERI and job satisfaction among the medical staff in Qom ***: A descriptive-correlative study was conducted on 202 medical staff in Qom Province based on random sampling in 2018. Demographics checklist, standard ILP, job satisfaction, and Siegrist’s ERI questionnaires were used for data collection. The chisquared test, independent t-test, and one-way Analyses of Variance(ANOVA) were used to analyze ***: The mean age of employees was 32.04 ± 7.9 years, and 165(87.1%) of the employees were women. The results showed that the medical staff was willing to leave their profession at a moderate level(40.7 ± 10.3). There was no significant relationship between demographics and ILP. Nevertheless, a significant and inverse relationship was observed between ERI(r:0.318, P < 0.01) and ILP(r: 0.197, P < 0.01). Leave the profession(LP) had a negative correlation with the dimensions of job descriptive index(JDI) such as job, manager, coworker and wage score(P < 0.01, r:-0.147, r:-0.262, r:-0.292, r:-0.271, r:-0.396).Conclusions: According to the results, managers need to make sure that their working staff is rewarded as they deserve. According to the results, managers need to ensure that the reward factor is observed for the staff, while an ERI imbalance may contribute to ILP of the staff. On the other hand, it leads to job satisfaction.
