Background: Survey of the occlusion in population groups usually include in their objections the academic assessment of occlusal feature, the planning resources for public health treatment programmers, the comparison of different population and the screening of groups for orthodontic treatment. Likewise a thorough investigation of the occurrence of malocclusions among school–students would be of major importance in the planning of orthodontic treatment in the public dental health services. For this purpose it is necessary to have detailed information on the prevalence of individual malocclusion among boys and girls at different ages distributed regionally, and moreover, an analysis of the need for orthodontic treatment in the different school classes. Materials and methods: This study was conducted from 20th October 2011 to 9th May 2013 on (3424 ) students (1712 males and 1712 females); from which 62 students (1.8%) were excluded because of incomplete information (no molar relation can be attended) giving a valid sample of 3362 (1681 males and 1681 females) aged (15) years old were studied with respect to facial profile ,sagittal occlusion according to Angle's classification, overjet, overbite, anterior crossbite , posterior crossbite, scissorsbite, rotation and displacement spacing and crowding. Results: The normal profile were presented in (73.76%) students (74%) males and (73.53%) females. Convex profiles were presented (20.34%) students (20.46%) males and (20.23%) females. A concave profile were presented in (5.9%) students (5.54%) males and (6.24%) females), The malocclusion were presented (73.05%) students (73.46%) males and (72.64%) females, According to the Dental health component of index of the orthodontic treatment subjects with no need for treatment were about 44.11% , the subjects who need little treatment were about 26.82%, 13.06% of the subjects who need moderate treatment, 10.03% great treatment need and about 5.98% very greatly treatment need. Conclusions: Orthodontic treatment need according to IOTN shows that there was no significant difference between males and females in the malocclusion, Facial profile and treatment need.
Importance of study :
The interesting of industrial sector and developing it after corner stone. It is important to build economic balanced and get behind and front linkage for transformative industrials, and this is important to get balanced.

this research is to identify the level of information awareness of the chemistry students in their fourth year studying at Ibn Al-Haytham Education College of pure sciences at the University of Baghdad. The research sample consisted of (107) male and female students out of the total number of (153) students studying during the (2017-2018) academic year, The sample therefore represents 71% of the total students. The research methodology used consisted of two parts. The first part is concerned with measuring information awareness using a multiple choice type of test related to (40) issues. The students were required to select the between (5) alternative answers for each issue. The objectives of the test and the issues used are to measure the

The standard ISA (610) requires the external auditors to assess independence, the scope of internal audit unit, competence, and due professional care of internal auditors as indicators that reflect the quality of internal audit performance before deciding to rely on internal auditors.
The sample of this study consisted of external auditors in Iraqi Solidary Companies for Auditing. A questionnaire was distributed to them via e-mail

In the present work, a d.c. magnetron sputtering system was designed and fabricated. The chamber of this system was includes from two copper coaxial cylinders where the inner one used as a cathode (target) while the outer one used as the anode with Solenoid magnetic coil located on the outer cylinder (anode). The axial profile of magnetic field for various coil current (from 2A to 14 A) are shown. The plasma characteristics in the normal glow discharge region are diagnostics by the 2.2mm diameter Langmuir probe with different length along the cathode and located at different radial positions 1cm and 2cm from the cathode surface. The result of this work shows that, the electron energy distributions at different radial positions along the
