Background: Penetrating neck injuries are common problem in our country due to increasing violence, terrorist bombing and military operations.
These injuries are potentially life threating and need great attention and proper management.
Objective: The aim of this study is to focus on the importance of anatomical zonal classification of the neck in the management of penetrating injuries of the visceral compartment of the Neck.
Methods :70 patients with various injuries who were managed at causality unit and Otolaryngology department in Al-Kindy Teaching Hospital during aperiod from January 1st 2015 to October 31st 2015.
The study carried on those patient depending on proper clinical examination and their urgent management.
Results : Both civilian and military patients were admitted to the hospital, 34 patients (47.2%) in their 20s age group, while only 2 (2.8%) in 60s.
High percentage of penetrating neck injuries in zone , 48 patient (68.6%) and lowest in zone , 6 patients (8.5%).
40 patients (57.1%) presented with tracheal and laryngeal injuries and 12 patients (17.5%) were with pharyngeal injuries, 4 patients (5.7) were with recurrent laryngeal nerve injury and 13 patients (18.5%) presented with vascular injuries.
Radiological examination done for 53 patients (75%) and we found foreign bodies in 30 patients (56.6%), tracheal deviation in 4 patients (7.5%) and emphysema in 19 patients (35.8%).
Tracheostomy done in 51 patients (72.8%) neck, exploration in 20 patients (28.5%) and a 9 patients (12.8%) treated conservatively.
Conclusion: Zonal classification of penetrating neck injuries was helpful in the management. Our study explains demographics and location of the injuries. Young men involved in violence and bombing was at high risk.
Zone with involvement of trachea, larynx and pharynx were most common areas of injuries.
Recommendations
Anatomical zone classification should be used as a guideline in management of penetrating neck injuries. (Trauma lifesaving guideline).Tracheostory should be practiced by every doctor in casualty unit. Team of surgeons and anaesthiologist should be always ready for any intervention with patient present to the casualty unite with a penetrating neck injury. Emergency medicine medical practice must be presents in every casualty unit to deal with insults.
Aim of the study
1.To recognize penetrating injuries of the neck according to the anatomic neck zones.
2.Identify the outcome of their treatment
An investigation was conducted for dewaxing of lubricating oil fraction by urea to reduce the pour point.In this study mixture of 45 % methyl ethyl ketone (MEK) and 55 % toluene was used as a solvent. The studied variables are mixing time (10-70 min), solvent to oil volume ratio (0.5:1- 2:1), urea to wax weight ratio (2- 6) and constant mixing speed 1500 rpm. By analysis of the experimental results, the best operating conditions achieved are mixing time 40 min, solvent/oil 2:1 volume ratio, and urea/wax 4:1 weight ratio. At these conditions the pour point of the lubricating oil decreases from 24 ° C to -13 °C.
Preparation of epoxy/ TiO2 and epoxy/ Al2O3 nanocomposites is studed and investigated in this paper. The nano composites are processed by different nano fillers concentrations (0, 0.01, 0.02 ,0.03, 0.04 ,0.05 ,0.07 and 0.1 wt%). The particles sized of TiO2,Al2O3 are about 20–50 nm.Epoxy resin and nano composites containing different shape nano fillers of (TiO2:Al2O3 composites),are shear mixing with ratio 1 to 1,with different nano hybrid fillers concentrations( 0.025 ,0.0 5 ,0.15 ,0.2, and 0.25 wt%) to Preparation of epoxy/ TiO2- Al2O3 hybrid composites. The mechanical properties of nanocomposites such as bending ,wearing, and fatigue are investigated as mechanical properties.
The problem of this research is:
What are the sustainable development goals that received the priority in the press addressing of the newspapers under study?
What are the journalistic arts adopted by these newspapers in addressing the sustainable development goals?
What are the journalistic sources that Arab newspapers depended on when addressing the sustainable development goals?
What are the geographic range the Arab newspapers adopted in addressing the sustainable development goals? The research is categorized into descriptive research, adopting the survey method, and using the content analysis method.
The sample of research was determined by the preparation of the Arabic newspapers (Al-

These are most copious in the liver and spleen;therefore, infection leads to an expansion of both of them. This study determined the burden of visceral leishmaniasis (VL) infection on liver and spleen. A total of 20 mice were infected peritoneally with 2x107promastigotes of Leishmania donovani / ml and other 12 mice left without infection as a healthy control. The weight of whole body, liver and spleen were measured and the histological development using hematoxylin and eosin stains were determined after 15, 30, 45-and 60-days post infection. The results represent that the mean weights of liver and spleen were increased in inf
