This research is done in an experiment by plaster in the circumstances of Homs. The aim of this paper to study the effect of adding four different levels of phosphogypsum as much as (0.00, 6.72, 13.44, 20.16)ton / hectare (three replicates for eac h treatment) on bulk density and structure stability for clay soil has taken from (Kattina). The results showed improvement in the stability of the structure of soil specially (0.25-1)mm, increasing in aggregation degree , increasing of the rate of total porosity ,air filled porosity in comparison to the control at the two levels(13.44, 20.16)ton/hectare and also by increasing the added level . Whereas the dispersion ratio , and Bulk density were decreased when increasing the level of phosphogypsum at the same two levels. The main achieved results in this study showed , a significant increase in aggregation degree in the soil when increasing the ratio of the added phosphogypsum at the levels( 6.72, 13.44, 20.16) in comparasion with control . In other way the dispersion ratio was decreased and had negative relationship when increasing the level of the added phosphogypsum in comparasion with control .
The Dams are large and complex projects, and are generally characterized by the enormous cost of implementation in some cases, and the length of the implementation period, are rarely carried out a dam in Syria within the estimated plan which develo ped his of the cost and time, this is due to the risks that intercepted projects during the implementation phase and directly influenced the basic project objectives ( cost and time and quality). This research experiences to the reality of the implementation of the late dams, through undertake a study the risks suffered by the implementation of sector and influenced the basic objectives of the project (cost - time - quality), through a field survey study includes more than thirty-five dams in Syria. For this purpose have been used survey was distributed to a slice of experts and technicians in the form of dams, has enabled to obtain a list of the risks faced by the implementation of dams in addition to the assessment, In an attempt to develop a scientific methodology to analyze and manage the risks of dam projects by assessing the probability of their occurrence and their impact on the objectives of the project in the event of occurrence, with introduce a new standard for evaluating a detection / control, As per the approach to FMEA /Failure Mode and Effect Analysis/ and incorporate logic fuzzy, and arrange those risks according the Risk Criticality Number (RCN) for each risk early in order be sensitive to them than we can handled properly with proposing appropriate response strategies.
Changing is a natural Phenomenon. It guides all of existents apparent in different fields. But transformation is another exercise to make a change in different fields of human life in nature, moral, politic, economic, and others fields. We have t wo ideas: changing and transformation. There is so much difference between these two ideas, though they have the same source, but this difference is connected with nature of act. The important matter which we are trying to clear is the ability and capacity we can benefit from in changing and transformation as they spontaneous operation. To have these benefits we are studying these two ideas from those conceptions, particularities of the nature of this act.
We suggest to model human-annotated Word Usage Graphs capturing fine-grained semantic proximity distinctions between word uses with a Bayesian formulation of the Weighted Stochastic Block Model, a generative model for random graphs popular in biology , physics and social sciences. By providing a probabilistic model of graded word meaning we aim to approach the slippery and yet widely used notion of word sense in a novel way. The proposed framework enables us to rigorously compare models of word senses with respect to their fit to the data. We perform extensive experiments and select the empirically most adequate model.
In this paper, we introduce a continuous mathematical model to optimize the compromise between the overhead of fault tolerance mechanism and the faults impacts in the environment of execution. The fault tolerance mechanism considered in this rese arch is a coordinated checkpoint/recovery mechanism and the study based on stochastic model of different performance critics of parallel application on parallel and distributed environment.
