The aim of this research is to use robust technique by trimming, as the analysis of maximum likelihood (ML) often fails in the case of outliers in the studied phenomenon. Where the (MLE) will lose its advantages because of the bad influence caused by the Outliers. In order to address this problem, new statistical methods have been developed so as not to be affected by the outliers. These methods have robustness or resistance. Therefore, maximum trimmed likelihood: (MTL) is a good alternative to achieve more results. Acceptability and analogies, but weights can be used to increase the efficiency of the resulting capacities and to increase the strength of the estimate using the maximum weighted trimmed likelihood (MWTL). In order to perform this research, the need for detection and investigation of the impact of pollution of the Tigris River in Kut city was necessitated by wastewater, particularly TDS dealt as dependent variable, and the impact of three pollutants (PO4, CL, SO4) that represented explanatory variables. In order to achieve this goal, a sample of (91) samples was drawn and checked in the laboratory of the directors of Kut city. Root of Mean Squared Error: RMSE was used as comparison criterion.

A language is a kind of substitution. A vocal disorder that may be a disease of speech, and it is one of the obstacles caused by organic and congenital causes, perhaps the common one is genetic.If we separate between lisping in children and separating it from what happens in adults, we find that lisping in children may have psychological causes as well as other ones, this is what we will show in this research.
Key words: psychological factor,lisps,children,vocal study .
IF we called twentieth century, the century of productivity and information revolution, the suitable address for twenty-first century is (( The quality century )) .
The research aims to initiate Arabic prize for quality to apply concepts and strategies of total quality management at Higher education sector, which is a vital sector and it may be the most importance sector because it provide efficient human manpower working at all other sectors.
The suggested prize take in consideration the specialty of this sector, and when we apply perspectives of this prize this will promote Arabic universities performance as well as the quality of graduates.
The importance of this research due to the necessity of this pri
