in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
Orifice-weir structures are being used to reduce peak drainage rates and to store water during the growing season in poorly drained pine plantations. Earlier studies have demonstrated their effectiveness in reducing drainage outflows while conserving water during the growing season. This study reports on criteria and preliminary guidelines for designing such structures. The guidelines were deve...
Information about hydrological systems and water table fluctuations is important for water management and is needed to assess choices for long-term water management policy. Preferably, uncertainty about the future water table depths is quantified to enable risk assessment. The aim of this study is to map water table depths and quantify the associated uncertainty, in order to indicate extreme sc...
A water-table dependent reservoir model to investigate the effect of drought and vascular plant invasion on peatland hydrology. Author manuscript, published in "Journal of Hydrology (2013) 32 p." 2 ABSTRACT: This paper investigates the water table dynamics in a peatland showing a wide range of water table fluctuations. A reservoir model of water table fluctuations in a double-porosity peat is p...
Regarding the importance of the watershed plans on one hand and extensive effects of these plans in the rural regions on the other hand, the main purpose of this descriptive-correlative survey was to identify and analyze the effect of watershed plans implement in Deh Jalal village in Zanjan province. The statistical population of this study consisted of all the heads of households of Deh Jalal ...
the purpose of this study was to find the relationship between critical thinking and self-regulation with reading comprehension of iranian female elementary language learners. the present study is a correlational one having a descriptive design. two questionnaires, critical thinking questionnaire and self-regulation questionnaire which were valid and reliable questionnaires and four reading com...
background when a primary radiation interacts with a medium, the secondary radiations are produced, that the contribution of these secondary radiation should considered in the calculation of dose. build-up factor is a dosimetric correction factor to assume effect of secondary radiation in calculation of dose. calculation of this factor is very difficult and time consuming. due to significance o...
Acknowledgments First of all, I would like to thank God for giving me good health and patience to complete this work. I would foremost like to thank my family and close friends who have always given me unlimited support and encouraged me through this effort. This thesis is also dedicated to my deceased mother who has given me her protection from heaven. Special acknowledgment is also dedicated ...
Peatland carbon and water cycling are tightly coupled, so dynamic modeling of peat accumulation over decades to millennia should account for carbon-water feedbacks. We present initial results from a new simulation model of long-term peat accumulation, evaluated at a wellstudied temperate bog in Ontario, Canada. The Holocene Peat Model (HPM) determines vegetation community composition dynamics a...
