The Current research aims to identify ( The effects of 4EX2 Model in Misconception of Chemical concepts and Higher Order Thinking for the Students of the Third grade average ) , To verify the objective of this research , the researchers added nul hypothesis following : There is no difference is statistically significant at the level of ( 0.05 ) between the average scores of students who studied 4EX2 Model and the average students who studied by using the Misconception of Chemical concepts and Higher Order Thinking test. The research was conducted on a sample of the average Third grade students in a Baghdad secretary for boys affiliated to the General Directorate for Educational in Baghdad Al – karkh 3 and for academic year ( 2015 – 2016 ) , the researchers adopted a two Experimental design as research sample ( 86 ) students from the average Third grade students were Selected randomly by the division of A by ( 43 ) students stood to represent the control group , who studied by using traditional method and the Division B by ( 43 ) students groups to represent the Experimental group that studied 4EX2 Model and rewarded the two groups in the Variables (chronological age in months and collection former in the subject of chemistry, previous and chemistry, information , Misconception of Chemical concepts) , and has one of the researchers thought himself by the two groups in two servings per week for each group , was preparing , Misconception of Chemical concepts test including ( 60 ) were verified face validity , by submitting it to a group of specialists , then applied on a prospective sample to calculated the discriminatory power of the item of the test was calculated construct validity and factor validity have been confirmed persistence of the codur retchrdson(20)reliability coefficient ( 0.82 ) . Using simplest t – test with the two ends of the two independent sample were null hypothesis testing yielded results in terms of statistically test. There is a statistically significant difference between the average degree of the experimental group wich used 4EX2 model and the control group in the the Misconception of Chemical concepts test for the experimental group, In the results of researchers sees the need to : 1- A adoption specimen 4EX2 Mode in teaching physics and included in the curricula and teaching methods course in colleges of education . 2- Conduct similar studies in several stages of study materials and to know their impact on other variables.

Objective: To review and see the pattern of histopathological diagnoses of one year appendectomy specimens.
Methodology: This retrospective study was carried in Sulaimani Teaching Hospital over the period of one year (from 1st
of January to 31st of December 2009). All pathological reports were reviewed retrospectively for patient’s age, sex,
histopathological diagnosis and operative findings (if present). Histopathological diagnoses then were classified into
either positive or negative for acute inflammation. Any associated findings or any surgical specimen removed with the
appendix was recorded. The obtained data were analyzed by using the statistical package social sciences (SPSS) version

The distribution of chilled water flow rate in terminal unit is a major factor used to evaluate the performance of central air conditioning unit. In this work, a theoretical chilled water distribution in the terminal units has been studied to predict the optimum heat performance of terminal unit. The central Air-conditioning unit model consists of cooling/ heating coil (three units), chilled water source (chiller), three-way and two-way valve with bypass, piping network, and pump. The term of optimization in terminal unit ingredient has two categories, the first is the uniform of the water flow rate representing in statically permanents standard deviation (minimum value) and the second category is the maximum heat transfer rate fro
