Background : The number of primary hip arthroplasty is growing with every passing year. At present this surgical operation has no equal in the rate of yielding good results. Despite the fact that in many cases in the long term after surgery radiolucent lines around the cup are observed, the clinical outcomes remain satisfactory.
Aim of the study :To study the clinical and radiological manifestations of the aseptic loosening of the endoprosthesis
Methods: This is a prospective study based on an analysis of diagnostic findings of 51 patients with aseptic loosening of hip joint components, aged 30 to 84 years. We depend for diagnosis of a septic losing by both clinical evaluation and X-ray assessment Results:The majority of clinical and radiological evidence of aseptic loosening appear after three years (47%).All our patients had a pain syndrome of varying intensity, with (43.2%) used a walking-stick. Shortening limb from 1 to 7 cm was found in 43 patients 85.2%.
The aseptic losing are common in cementless hip prosthesis especially in femoral stem part of prosthesus 53.9% versus 25.6% in cemented type,
Revision surgery for primary hip prosthesis occur mainly for femoral stem involve 49% while other 25.5% involve both acetabular cup and femoral stem, while the rest of patient(25.5%) involve revision of acetabular cup only. Discussion :At present this surgical operation has no equal in the rate of yielding good results. The lifetime of the majority of artificial joints does not exceed 15 years mainly due to aseptic loosening of one or both endoprosthetic components There are many causes of aseptic instability: substandard surgical technique, unwarranted extension of the indications for arthroplasty, inappropriate choice of the prosthesis dimension type, incorrect installation of components, reaction to the massive foreign body and the development of synovial-like membrane on the metal-bone interface .
As a rule, early instability within 1 year was associated with defects in the operative techniques, from 1 to 3 years mostly due to the wrong selection of the type of primary endoprosthesis while more than 3 years period, the instability was caused by two reasons: excessive load on the operated extremity or traumas and the rapid wear of plastic with large areas of osteolysis due to the high loads or inaccurate positioning of the prosthetic cup.
Conclusions: X-ray examination is the fundamental for diagnosing of aseptic loosening of hip endoprosthesis , and improved surgical techniques, the proper selection of the type of prosthesis are the keys for reduction of risk of aseptic loosening
Nowadays laser in medicine is a rapidly growing field in both researches and applications and many studies have been done in bacteriology against different types of lasers. The effect of the laser depends on many factors, one of the laser factors was the wavelength. The red wavelength band has been considered as a stimulated wavelength for prokaryotic and eukaryotic cells. In this study, three clinical species of Gram-negative bacteria (E. coli, Proteus mirabilis, and Pseudomonas aeruginosa) were exposed to 650 nm band of red region wavelength by a diode laser. The effect of that wavelength appeared on the growth curves for each species along 3 days after laser treatment. The energy density (E.D.) 2.8 J/cm2 gave a positive effect on grow

Lately great interests have emerged to find educational alternatives to teach and improve motor skills according to modern educational methods that take into account individual differences and speed in learning for the learner through individual learning that the learner adopts by teaching himself by passing through various educational situations to acquire skills and information in the way he is The learner is the focus of the educational process and among these alternatives the interactive video, the researchers noted through the educational training units at the Model Squash School of the Central Union, and that most of the methods and methods used in learning basic skills take a lot of time in the educational program and do not involve

This research is an attempt to define the concept of journalistic information pollution, and what are the causes and sources of this pollution. The research applied the descriptive research method to achieve its objectives. A questionnaire was used to collect data. The findings indicate that journalists are aware of the existence of information pollution in journalism, and this pollution has its causes and resources.
Iraq suffers from serious pollution with harmful particles that have important direct and indirect effects on human activities and human health. In this research, a system for detecting pollutants in the air was designed and manufactured using infrared laser technology. This system was used to detect the presence of pollutants in the dust storms that swept the city of Baghdad which could have a negative impact on human health and living organisms.
The designed detection system based on the use of infrared laser (IR) with a wavelength of 1064 nm was used for the purposes of detecting pollutants based on the scattering of the laser beam from these pollutants. The system was aligned to obtain the best signal for the scattered rays, w
