By investigating how educational practitioners participate in activities around open educational practices (OEP), this paper aims at contributing to an understanding of open practices and how these practitioners learn to use OEP. Our research is guided by the following hypothesis: Different social configurations support a variety of social learning activities. The social configuration of OEPs i...

Though it is vital to estimate infiltration as one of the key factors in effective management of water resources, only few studies have been carried out either to determine the infiltration or to compare the performance of infiltration models for coarse textured soils. Thus, the present study was conducted to accomplish two objectives. First to estimate the Horton’s infiltration model parameter...

Plant protection based on novel alternative strategies is a major concern in agriculture to sustain pest management. The marc extract of red grape cultivars reveals plant defence inducer properties. Treatment with grape marc extract efficiently induced hypersensitive reaction-like lesions with cell death evidenced by Evans Blue staining of tobacco leaves. Examination of the infiltration zone an...

soil infiltration characteristics affect the design, evaluation and management of furrow irrigation over afield. on the other hand, different variables influence furrow infiltration, making infiltration modeling for afield a complex process. this study was conducted to investigate the direct and indirect effects of allvariables affecting furrow infiltration. the blocked furrow method was used t...

Land application of sewage sludge requires careful monitoring because of its potential for contamination of surface water and ground water. A rainfall simulator was used th investigate the effects of freshly applied sludge on infiltration, and on runoff of sediment and nutrients from agricultural crop lands. Rain was applied to 16 experimental field plots. A three-run sequence was used to simul...

Infiltration is the process of water penetration from the ground surface into the soil and is an important process in the hydrological cycle by which surface runoff and groundwater recharge can be linked. Over the years, the importance of the infiltration process resulted in the development of several simplified analytical models for predicting infiltration. These infiltration models range from...

DDesigned and undersigned fires in rangelands affect vegetation and soil, and then are necessary to give enough knowledge about them. Infiltration is one characteristic that have predict had affected by fire but had not studied enough yet. So spot fire have been seen in Artemisia aucheri type in Charat sub watershed at Mazandaran province, in this research were investigated primary, final infil...
