The method of powder technology has been utilized in fabrication of machinable
ceramics by the approach of glass-ceramic principles. The crystalline ceramic phases
partially dissolved by host glass while the undissolved part remain responsible for the
machinability by the usual cutting tools. Thus avoiding the unnecessary use of special
dies to cast fully melted composition and initiate recrystallization process. Two types of
machinable ceramics have been successfully prepared, the first with high silica content
and the other with high alumina content. A comparison of their properties and discussed.

Reliability has an important role in both the industrial and engineering applications. So the need for Reliability Tests appeared are series of tests a discover out of factors that  appear through the test, knowledge limit of fit a specifics production addition for getting on goodness of production.

Therefore, the need for research to test for censor data from ( Type II ) for exponential distribution with one parameter and that test it’s (Reliability Growth) includes three curves are Idealized Growth curve estimation parameters and reliability with maximum likelihood method, Duane Growth curve takes estimation parameters and reliability with least squares method, Exponential Reliability Growth Cur

This study aimed to study the inhibition activity of purified bacteriocin produced from the local isolation Lactococcuslactis ssp. lactis against pathogenic bacteria species isolated from clinical samples in some hospitals Baghdad city. Screening of L. lactis ssp. Lactis and isolated from the intestines fish and raw milk was performed in well diffusion method. The results showed that L. lactis ssp. lactis (Lc4) was the most efficient isolate in producing the bacteriocin as well observed inhibitory activity the increased that companied with the concentration, the concentration of the twice filtrate was better in obtaining higher inhibition diameters compared to the one-fold concentration. The concentrate

The aim of present investigation was Litilizing cow, sheep and chicken bones that included both hollow and flat to produce fat. The extraction rat was increased propotionally with rising temperature and extraction time for both cow and sheep bones. The lowest extraction rat form hollow and flat bones for cow and sheep was 12.66, 6.55, 6.93 and 7% respectively at 60°C for 3 hours. The highest extraction rat for hollow cow bones was 21.90% at 90°C for 5 houers, values for flat cow bones, hollow and flat sheep bones was 15.04, 16.4 and 12.8% respectively at 100°C for 5 hours. While, hollow and flat chicken bones resulted lowest extraction rate, thus thermal treatment was conducted only at 90 °c and showed propotional increase with incre

Abstract :

          Researchers have great interest in studying the black box models this thesis has been focused in the study one of the black box models , a ARMAX model which is one of the important models and can be accessed through a number of special cases which models (AR , MA , ARMA, ARX) , which combines method of the time series that depend on historical data and and regression method as explanatory variables addition to that past errors , ARMAX model importance has appeared in many areas of application that direct contact with our daily lives , it consists of constructing ARMAX model several traditional stages of the process , a iden

         The availability of statistical data plays an important role in planning process. The importance of this research which deals with safety of statistical data from errors and outliers values. The Objective of this study is to determine the outlier values in statistical data by using modern exploratory data methods and comparing them with parametric methods. The research has been divided into four chapters ,the main important conclusions reached are:1-The exploratory methods and the parametric methods showed variation between them in determining the outlier values in the data.

2-The study showed that the box plot method was the best method used in determining
