This book provides a comprehensive treatment of the cavitation
erosion phenomenon and state-of-the-art research in the field. It
is divided into two parts. Part 1 consists of seven chapters,
offering a wide range of computational and experimental approaches
to cavitation erosion. It includes a general introduction to
cavitation and cavitation erosion a detailed description of
facilities and measurement techniques commonly used in cavitation
erosion studies, an extensive presentation of various stages of
cavitation damage (including incubation and mass loss) and insights
into the contribution of computational methods to the analysis of
both fluid and material behavior. The proposed approach is based on
a detailed description of impact loads generated by collapsing
cavitation bubbles and a physical analysis of the material response
to these loads. Part 2 is devoted to a selection of nine papers
presented at the International Workshop on Advanced Experimental
and Numerical Techniques for Cavitation Erosion
Prediction (Grenoble, France, 1-2 March 2011) representing
the forefront of research on cavitation erosion. Innovative
numerical and experimental investigations illustrate the most
advanced breakthroughs in cavitation erosion research.

The aims of the present study were to development, validation and
normalization of mathematics anxiety scales (MAS), as an instrument
to measure students' Mathematics anxiety for high schools . By
using all of aspects of Mathematics anxiety a primarily
questionnaire with 96 item was developed and piloted based on a
sample of 2400 students. Data entry was performed using descriptive
statistics, exploratory and confirmatory factor analysis and
goodness of fit by SPSS and Lisrel soft wears. Analyzing the data
extracted two factors for mathematics anxiety as math test anxiety
and numerical anxiety. Psychometric properties of reliability and
validity have shown significant results and are improved remarkably
that this instrument can be considered as a suitable criterion for
prospective clinical interventions. The MAS linked a communication
gap between students and teachers. Through use of the scale,
students, teachers and counselors are able to work together towards
improving Mathematics courses and increasing Mathematical literacy.
