One of the problems found in the dam reservoirs is the sedimentation of cohesive sediments just upstream of the dam. By increasing the sediment volume, the CONSOLIDATION PROCESS is initiated and the sediments will be consolidated over time. To dredge or flush these sediments either through mechanical or hydraulic PROCESSes, it is important to determine the physical properties of consolidated sediments. An experimental study was conducted to investigate the mechanism of CONSOLIDATION for submerged cohesive sediments. In order to identify and review the sedimentation and CONSOLIDATION PROCESSes for cohesive sediments and to define the required physical parameters, a physical test model consisting of a Plexiglas cylindrical tube with a diameter of 30 cm and a height of 3,5 m was constructed. Experiments were carried out on the cohesive sed. with various initial heights and density. During the initial hours of the test, water within the test cylinder was muddy, yet the sediments gradually began to settle and a visible sediment – water interface was formed and it was possible to measure the CONSOLIDATION PROCESS. in the model. Results of this study show that the sedimentation and CONSOLIDATION PROCESS is not only affected by the type of water and sediment but also the initial height and density of the water and sediment mixture. The developed dimensionless parameters revealed a correlation between various experiments with different initial height and density. The results of the study also reveal a four separate logarithmic relationship between sediment density and time in the sedimentation and CONSOLIDATION PROCESS.

In this article, based on the current historical data on the emergence and development of the Human Sciences, we looked at this thinking approach that different social forces were placed together-in a coordinated or opposite way-and made possible the acquisition of the available sciences, especially the Humanities. Given the nature of the issue, the research method was a historical analysis and the method of data collection was documentary. The researchers tried to review systematically and coherently, the context and historical conditions in the PROCESS of the development of the Humanities. In this research, we showed that the humanities appeared discursively in terms of breakdowns, inequalities and divisions (1796-1831). Two events of coincidence and inconsistencies during cholera, defeat from Russia and the arrival of French and British forces to Iran were the background for acquisition of the humanities. Through discourse acquisition of the humanities, the ground for discourses conflict was provided in Iran, and through this conflict, the humanities discourses became problematic (1941-1953). We also showed that contrariwise to the humanities discourse that has always been dominated by conflict and hostility, humanities institutions have been drafted in the era of security and authority of government. The CONSOLIDATION of the humanities has been the result of two distinct periods in terms of security (humanities institutions) and conflict (humanities discourse).

How to profoundly change the beliefs of the polytheists during the age of revelation from the denial of the Prophet (pbuh) to the certainty of his Message and the acceptance of his full guardianship is a question worthy of attention. The order of verses about prophecy based on the order of revelation is the reason to lead a transformative PROCESS and a special Quranic method in institutionalizing the belief of prophecy in the lives of Arabs. In the first stage, the Holy Quran in the first Makkī (Arabic: المکّیّ, suras revealed in Mecca) chapters has prepared the community from the motivational side to accept the truth of the Prophet’s (pbuh) prophecy and briefly stating the key issues surrounding it. The Holy Book of Quran at the time of the emergence of oppositions and doubts (the second stage) destroyed the arguments of the polytheists and explained the prophecy and proved its authenticity from a cognitive perspective in the second stage by presenting clear arguments. and the Holy Book of Quran in the third stage after Madanī (Arabic: المدنیّ, suras revealed in Medina) period has undertaken measures in order to fulfill the goals of the Massage by explaining the true position of the Prophet (pbuh) to deepen and operationalize the Prophetic belief through explaining practical duties for the Prophet (pbuh) and behavior based on the acceptance of Walaya (Arabic: ولایة, meaning “guardianship” or “governance”).

A formulation of the Element Free Galerkin (EFG), one of the mesh-less methods, is developed for solving coupled problems and its validity for application to soil-water problems is examined through numerical analysis. The numerical approach is constructed to solve two governing partial differential equations of equilibrium and the continuity of pore water, simultaneously. Spatial variables in a weak form, the displacement increment and excess pore water pressure increment, are discretized using the same EFG shape functions. An incremental constrained Galerkin weak form is used to create the discrete system equations and a fully implicit scheme is used to create the discretization of the time domain. Implementation of essential boundary conditions is based on penalty method. Examples are studied and the obtained results are compared with closed-form or finite element method solutions to demonstrate the capability of the developed model. The results indicate that the EFG method is capable of handling coupled problems in saturated porous media and can predict well, both soil deformation and the variation of pore water pressure, over time.

Vertical drains installation can be used to accelerate the CONSOLIDATION settlement. In this research, three dimension equation of CONSOLIDATION in cylindrical coordinate with certain boundary condition was obtained and the analytical solution was performed. Then, the results at the MATLAB were written and the variation of degree of the settlement versus time was investigated. The results with experimental data of odoemeter test were also compared. The account of radial drains in this model were considered 0.5, 1, 1.5 and 2 cm. To verify the analytical solution, in the isotropic soils and zero radius of the vertical drain, the results and the traditional Terzaghi's method were fully established with suitable satisfactory. The results showed. The most difference of 100% settlement velocity between of Terzaghi method and radial-vertical method was related to 40kg loads at the drain's with 2 cm radius. This amount was 6 hr, however, the least of difference time of 100% settlement velocity was related to 5 kg loads at the drains with 0.5 cm radius and this time is 1 hr. However, results showed the analytical solution in comparison to numerical methods are predicted less time of average degree of CONSOLIDATION as more accuracy.

In recent decades numerical modeling of self-weight CONSOLIDATION of very soft soils which has a number application in the analysis of CONSOLIDATION of dredged materials and deposited materials behind tailing dams, has attracted special attention.In this paper, by considering large strain effects and variation of permeability and compressibility of soft soils during CONSOLIDATION, and employing a new technique for discretization of spatial domain during stage filling, a finite difference based computer program has been developed that is capable of modeling different scenarios of self-weight CONSOLIDATION. Then the performance of the model for analyzing of practical applications has been evaluated via comparing the model results with measured values in the site as well as computer programs results that have been verified previously.

Background and aims: The extensive studies examined necessary offline periods for happening CONSOLIDATION enhancement in implicit and explicit memory in humans and obtained conflict findings. This study was aimed was to compare the effect of different offline periods on enhancement-based CONSOLIDATION PROCESS in implicit motor memory.Methods: In this semi- experimental research, 60 health female students in the range of 20-30 years old were selected in convenience way and randomly divided into three groups with distance of 6, 24 and 72 hours in offline periods. This research consisted of two phases of learning and retention and serial reaction time task was used for this research. Data were analyzed using ANOVA with repeated measure and Bonferroni Post Hoc tests.Results: Results showed that in skill learning stage, group main effect and interaction effect between groups were not significant (P>0.05), but epoch main effect was significant (P<0.05), and practice led to decrease the reaction time in fifth epoch compared to other epochs. In retention stage, the epoch main effect and its interactive effect between group and epoch were significant (P<0.05). Furthermore, results showed that three groups in retention test epoch have better performance rather than epoch 5 in learning stage. Bonferroni Post Hoc tests showed that practice in group with 24h offline period appeared the better performance in reaction time rather than two other groups (P<0.05).Conclusion: The search results indicated that make offline period after learning phase could be facilitated the implicit motor memory CONSOLIDATION.
