... Show Morethis paper consists of three sections, Section one deals with the most important difficulties and characteristics of English subordinate clauses whereas section two tackles the difficulties faced by the Iraqi EFL students at the third year in the Department of English, College of languages, University of Baghdad in recognizing and producing the subordinate clauses submitting them to a test consisting of two questions (recognition and production). Finally, some pedagogical recommendation of the findings can be found in section four.
The revolution in technology made students plagiarize others’ work and submit it as their own. The aim of this study is to find the effectiveness of teaching paraphrasing strategies in reducing students’ plagiarism in university of Baghdad. The Sample of the study is randomly chosen out of eighty, fourth year college students. The materials were taught within eight weeks of instruction about paraphrasing strategies. Results represent that treating the experimental group with paraphrasing strategies have resulted in expanding the range of avoiding plagiarism in the post-test. Moreover, the findings showed that plagiarism is a problem for the students at a college level and their assignment submitted during the course of study includes a

duration=300μsec) was used to perform drilling in samples of lead, stainless steel
304, brass, copper and aluminum. Laser irradiation was carried out in both air and
in a suitable chamber of controlled pressure inside. The effect of pressure inside the
chamber on the drilling process was investigated. Then, the chamber was filled with
argon gas to investigate its effect on drilling process where an enhancement in
drilling depth was observed compared to that in case of irradiation in air and
chamber of air pressure. As well, the effect of focus position on the process was
studied with the pressure varying inside the chamber in order to construct a

تم في هذا البحث دراسة الطرائق اللامعلمية الرتيبة لتقدير دالة الأنحدار اللامعلمي، ومعالجة القيم الشاذة الموجودة في دالة الأنحدار اللامعلمي لجعل الدالة رتيبة (متزايدة أو متناقصة).
لذا سنقوم أولاً بتقدير دالة الأنحدار اللامعلمي بإستخدام ممهد Kernel ومن ثم تطبيق الطرائق الرتيبة لجعل الدالة متزايدة إذ سنتناول ثلاث طرائق للتقدير:-

Show MoreThe repeated measurement design is called a complete randomized block design for repeated measurement when the subject is given the all different treatments , in this case the subject is considered as a block . Many of nonparametric methods were considered like Friedman test (1937) and Koch test(1969) and Kepner&Robinson test(1988) when the assumption of normal distribution of the data is not satisfied .as well as F test when the assumptions of the analysis of variance is satisfied ,where the observations within blocks are assumed to be equally correlated . The purpose of this paper is to summarize the result of the simulation study for comparing these methods as well as present the suggested
