Simulation of Temperature Distribution in TIG Spot Welds of (Al-Mg) Alloy Using Finite Element Method
...Show More Authors

      This research concern to analyse and simulate the temperature distribution in the spot welding joints using tungsten arc welding shielded with inert gas (TIG Spot) for the aluminum-magnesium alloy type  (5052-O).

      The effect of and the quantity of the heat input that enter the weld zone has been investigated welding current, welding time and arc length on temperature distribution. The finite element method (by utilizing programme ANSYS 5.4) is presented  the temperature distribution in a circular weld pool and the weld pool penetration (depth of welding) through the top sheet ,across the interface into the lower sheet forming a weld spot.                                                                                                     

      A three dimensional (3-D) model has been constructed to study the temperature distribution and the depth or penetration of the weld spot. The results showed that the weld zone and heat affected zone (HAZ) suffer from high temperature variation caused by severe thermal cycle. The temperature reaches the highest value of the melt metal at the weld spot 698°C at weld current 130 Amp, weld time 6 sec and arc length 1.6 mm, then drops further away from the weld spot in the direction  the base metal.

      Figuers were plotted to explain the results and to show the temperature distribution and its value in the weld spot  and heat effected zone.

THE ROLE OF ELECTRONIC MARKETING IN PROMOTING THE PRODUCTS OF THE NATIONAL INDUSTRY IN IRAQ: THE ROLE OF ELECTRONIC MARKETING IN PROMOTING THE PRODUCTS OF THE NATIONAL INDUSTRY IN IRAQ
...Show More Authors

ABSTRACT

The research aims to clarify the role of electronic marketing and what it can achieve in promoting the products of the national industry in Iraq. Marketing channel depends on modern communication and information technology that industrial and metal companies can use in promoting and selling their products along with traditional marketing outlets. To achieve the objectives of the research, a questionnaire was used, which consists of three axes, the first includes the personal data of the sample (gender, age, educational attainment, place of residence, marital status, income level), while the second axis includes various questions about the products of the national industry. Third axis includes que

The Reality of Evaluating Teacher Performance in the Sultanate of Oman in Light of Global Models
...Show More Authors

The aim of the research is to reveal the reality of teacher performance evaluation in the Sultanate of Oman in light of some global models. The study followed a qualitative descriptive research design. Seven forms of teacher formative and summative assessments were analyzed. Besides, an analytical template was developed, consisting of six areas related to the teaching performance of teachers. These included: lesson planning and preparation, learning environment, education, professional development, student academic, and community and parental partnership. The study reached a number of results; the most notable is the lack of change of forms for more than a decade despite the rapid development of the educational system in the sultanate in

A chemical study was carried out to evaluate the efficiency of the liver enzyme concertation and uric acid level and its antagonists in the serum of the professors exposed to chemicals in the laboratories of the University of Samarra and their comparison with the healthy people. The research included 25 samples of the exposed professors and 20 samples as a group of officers.

              The results of the current study showed a significant increase in the level of   AST, ALT in the serum of professors exposed to chemicals compared to healthy people. The results showed no significant increase in

Multiple and Coherent Noise Removal from X-Profile 2D Seismic Data of Southern Iraq Using Common Depth Point Muting Procedures and Depending on Madagascar Open-Source Package
...Show More Authors

This article describes how to predict different types of multiple reflections in pre-track seismic data. The characteristics of multiple reflections can be expressed as a combination of the characteristics of primary reflections. Multiple velocities always come in lower magnitude than the primaries, this is the base for separating them during Normal Move Out correction. The muting procedure is applied in Time-Velocity analysis domain. Semblance plot is used to diagnose multiples availability and judgment for muting dimensions. This processing procedure is used to eliminate internal multiples from real 2D seismic data from southern Iraq in two stages. The first is conventional Normal Move Out correction and velocity auto picking and

The nuclear charge density distributions, form factors and
corresponding proton, charge, neutron, and matter root mean square
radii for stable 4He, 12C, and 16O nuclei have been calculated using
single-particle radial wave functions of Woods-Saxon potential and
harmonic-oscillator potential for comparison. The calculations for the
ground charge density distributions using the Woods-Saxon potential
show good agreement with experimental data for 4He nucleus while
the results for 12C and 16O nuclei are better in harmonic-oscillator
potential. The calculated elastic charge form factors in Woods-Saxon
potential are better than the results of harmonic-oscillator potential.

Contradictions in experience of Criticism in Andalus Poetry
...Show More Authors

Metaphor has been occupied first place among eloquent methods to build metaphors;
poetry with the latter becomes senseless thing. Metaphor is necessary part of energy that
sustains the poetry. Sentence of metaphor regarded more eloquent than the reality since it
does not conduct directly to the meaning , but rather get to it indirectly. Metaphor is
considered one of the most tools for the poet since it is a means of expression about his
sensation and feelings . Andalus paid concerns over metaphors as that being incited by their
country beauty and nature. The poet might resort to contradiction as to picture contraries
within himself.
Through pictures of contradictions depicted by the poets , it has explained that t
