Goal  of  research  is  to  investigate  the  impact  of the  use  of  effective  learning  model in the  collection  of  the  fourth  grade  students/Department of  physics in the material  educational methods  and the  development  of  critical thinking  .to teach  this goal  has  been  formulated  hypothesis cefereeten zero  subsidiary  of the second hypothesis  .To  investigate  the  research  hypothesis  were  selected  sample  of  fourth-grade  students of the  department  of physics at the university for the academic year (2015-2016) the sum of its members reached (71) students .and distributed this sample in to two divisions.one representing the exberimental groub and the other group represents the control and by (35-36)students respectively.i was conducted parity processon the two sets of search variables(intelligence.the collection of physics for previous year .chronological age.critical thinking). It has been teaching the experimental groub .according to the model of effective learnin g and the control  group according to the usual way. The researcher creating the necessary supplies for research and of identifying scientific material and formulation of behavioral purposes of article specific and preparing  lesson plans teach the experimental and control groups.according to the model of effective learning and the way ordinary.as well as carrying out the provision of teaching aids and tools laboratory of application experience.and requests the search and there are two tools.The first achievement test in the supject of the teaching aids where the researcher prepared and be in its final form(45) paragraph checksums objective of pairing tybe (conforming) and multiple choice surgeon (fill in the blanks) has been marked by total test honesty and consistency have been extracted difficulty discriminatory and strength to the level of paragraphs and all werew ithin the acceptable rang the difficulty and discrimination as well as the effectiveness of alternatives to the wrong vertebrae multiple choice.the second tool they test critical thinking prepared by (al-alwani.1999)and be its final form of the (75)paragraph checksums distributed(5)areas to measure the mental capacity critic representative skills (finding.evaluating arguments knowledge of assumptions.deducation.interpretation)has only researcher extracted sincerity and persistence. Abblied exberience .starting from the first semester of the academic year (2015-2016) as has beenthe bar-test procedure for critical thinking of students on the research sample (18/10/2015)and began to exberiment on (19/10/2015)and lasted on antire semester by three hours aweek to be Total college classes(27hours) for each groub.the experiment was completed after the application tools(achievement test and test critical thinking posttest)date(24/12/2015).After date collection and statistical analysis using altaia test for two independent samples:showed results as follows

1-There is astatistically significant difference between the average achivevment of the two sets of research in educational material means and in the experimental group

2-There is a statistically significant difference between the average skill development (conclusion.deduction.interpretation .and critical thinking as awhole)to the tow sets of search and infavor of the experimental group.in light of the search results researcher came out with a number 0f conclusions including the effectiveness of the model of effective learning(activelearning)in the collection of the fourth grade students of the physics department at the material educational methods and the development ofcritical thinking compared to the usual way.the researcher recommended a number of recommendations.including the establishment of training courses for teachers of physics on the use of model and new strategies in teaching including a model of effective learning(active learning) as well as attention to jean-authored book include book physics intellectual and skill activities including stimulates the energies of students and enhances their thinking in general skills and critical thinking in particular.complementing the current research .scholar proposals for future research mode

D-Shaped Photonic Crystal Fiber Toxic Metal Ions (Arsenic) Sensor Based on Surface Plasmon Resonance
...Show More Authors

In this work, a Photonic Crystal Fiber (PCF) sensor based on the Surface Plasmon Resonance (SPR) technology was proposed. A thin layer of gold (Au) was deposited on a D-shaped Photonic Crystal Fiber (PCF), which was coated with plasmonic chemically stable gold material with a thickness of 40nm. The performance parameters like sensitivity including wavelength sensitivity and amplitude sensitivity and resolution were evaluated by simulation using COMSOL software. The proposed sensor was created by using the finite element approach, it is numerically examined. The results show that the surface of D-shaped Photonic Crystal Fiber coated with Au behaves as a sensor to detect the refractive index (IR) of toxic metal ions. The impacts of the str

Soft tissue sarcomas: Evaluation by immunohistochemistry
...Show More Authors

Soft tissue sarcomas represent a histologically heterogenous group of malignant tumors arising from the soft tissue compartments, i.e smooth muscles, skeletal muscles, adipose tissue, blood vessels, connective tissue mesenchyme, neural tissue and other tumors of uncertain histogenesis(1). Soft tissue sarcomas are relatively rare tumors, represent less than 1% of adult malignancies based on data report from American Cancer Society (2). The crude incidence rate in Iraq for soft tissue sarcomas was 219/ 100,000 population during 2014 with male: female ratio of 1.3:1, and highest peak age between 30-34 years (3). The histological subtype and microscopic criteria are two parameters that influence the tumor grade which is the best predictor fo
