The research aims to find a way to calculate the hydrodynamic and thermal characteristics of devices absorption foam used in the wet roads to clean the combustion products of SO2 to increase the effectiveness of these methods and economic. For it has been studied heat exchange and hydrodynamic device absorption with bilateral phase moving layer (foam) with different models of contact devices, and on the basis of experimental data and mathematical analysis have been obtained equations that allow assessment of the impact of contextual factors in the core layer foam variables. It was also stressed that the heat exchange in the field of foam layer is characterized by high efficiency heat exchange between the gas and the liquid in the foam layer and between the foam layer and the surface submerged, and give the temperature coefficient depends on the initial conditions of gaseous and liquid phase and the temperatures of the dew point of the gas and liquid teams at the entrance device absorption. As for the effectiveness of cleaning the combustion gases from the cleaning degree of SO2 in the upper border of the foam system up to (95,95%) on stage touches one. The study also allowed increase reliability for wet cleaning system by selecting the optimum poisoning and on the basis of data obtained.

Research summary
تهدف الدراسة إلى تطوير طريقة لحساب الخصائص الهيدروديناميكية والحرارية لأجهزة الامتصاص الرغوية المستخدمة في الطرق الرطبة لتنظيف نواتج الاحتراق من ثاني أكسيد الكبريت (SO2). تم إجراء دراسة تجريبية ومحاكاة رقمية لتبادل الحرارة والهيدروديناميكية في جهاز الامتصاص ذو الطبقة الرغوية ثنائية الطور. أظهرت النتائج أن التبادل الحراري في طبقة الرغوة يتميز بفعالية عالية بين الغاز والسائل، وأن معامل انتقال الحرارة يعتمد على الشروط الابتدائية للطورين الغازي والسائل وعلى فرق درجات حرارة نقطة الندى عند مدخل جهاز الامتصاص. توصلت الدراسة إلى أن درجة تنظيف غازات الاحتراق من SO2 تصل إلى 95.95% في مرحلة تلامس واحدة. كما أكدت الدراسة على أهمية اختيار التصميم الأمثل لزيادة وثوقية نظام التنظيف الرطب.
Critical review
دراسة نقدية: تعتبر الدراسة شاملة ومهمة في مجال تنظيف نواتج الاحتراق من SO2 باستخدام أجهزة الامتصاص الرغوية. ومع ذلك، يمكن توجيه بعض الانتقادات البناءة لتحسينها. أولاً، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل البيئية المختلفة على فعالية الأجهزة المستخدمة. ثانياً، كان من الممكن تضمين مقارنة بين فعالية الأجهزة الرغوية وأجهزة التنظيف الأخرى المستخدمة في الصناعة. ثالثاً، الدراسة تعتمد بشكل كبير على البيانات التجريبية، وكان من الممكن تعزيز النتائج باستخدام نماذج رياضية أكثر تعقيداً لتحليل البيانات. وأخيراً، لم يتم التطرق إلى التكلفة الاقتصادية لتطبيق هذه التكنولوجيا على نطاق واسع، وهو جانب مهم يجب مراعاته عند تقييم فعالية أي تقنية جديدة.

The research focused on the conclusion of a mathematical model to determine the proportion of nitrogen oxides emitted from the internal combustion engine based on the equations of chemical interaction of direct and reverse the conventional fuel wit h the use of many of the correction coefficients, as well as the possibility of developing this model. Search to find out the concentration of nitrogen oxides NO changes resulting from the combustion of fuel in internal combustion engines that run on diesel fuel and gasoline adopted, during work time, and then transform this relationship to calculate the ratio of the concentrations according to the angle of rotation of the engine crankshaft.
This study describes the improvement of the reliability and effectiveness of the straight flow used in piston compressors, valves, and by modeling the flow of gas and the movement of plate valve. This model distributes the gas pressure and distorti ons plate valve as a flexible plate to be determined. This modeling test gas flow through the valve in the static measurements in addition to dynamic measurements of the end plate valve movement in the compressor has checksum where the comparison between numerical results and experimental results measured.
The aim of this clinical study is to determine the efficiency of miswak (cleaning sticks – chewing sticks) in comparison with toothbrush in removingdental plaque from facial, lingual and interproximal surfaces and reducing Gingivitis. A total of 56 dental students who were divided into two groups were included in the study. This study was divided into two stages. The first stage, and after the experimental plaque accumulation, the volunteers cleaned their teeth (toothbrush or miswak) for five minutes. Then the clinical measurements were recorded. The second stage, the volunteers used according to their group either toothbrush and dentifrice or miswak twice a day for five minutes for three weeks. In the first stage, there was no difference between the two groups in gingivitis. The values of Turesky’s index to assess the plaque on facial and lingual surfaces were a little higher for miswak users, but the difference was statistically insignificant. While the cleaning of interproximal spaces was more evident in toothbrush users, either facial or lingual, and the difference was significant (P < 0.01). Generally, neither miswak nor toothbrush were able to produce completely interproximal dental health. So, the cleaning of facial surfaces by using toothbrush or miswak was better than lingual surfaces (P <0.05). In the second stage, the plaque and gingival values were higher in miswak users, but the difference was not significant. The result: miswak cannot remove dental plaque completely, but the site of plaque on the facial and lingual surfaces were almost similar to those among toothbrush users. Finally, a toothbrush possessed a clear superiority in cleaning interproximal spaces, thus making it the oral Hygiene aid of choice.
In this paper, spline approximations with five collocation points are used for the numerical simulation of stochastic of differential equations(SDE). First, we have modeled continuous-valued discrete wiener process, and then numerical asymptotic st ochastic stability of spline method is studied when applied to SDEs. The study shows that the method when applied to linear and nonlinear SDEs are stable and convergent. Moreover, the scheme is tested on two linear and nonlinear problems to illustrate the applicability and efficiency of the purposed method. Comparisons of our results with Euler–Maruyama method, Milstein’s method and Runge-Kutta method, it reveals that the our scheme is better than others.
In recent years the interest in renewable energy resources is increasing. Ethanol is considered as one of the promising alternative fuels. It has many advantages that make it an excellent motor fuel, Ethanol combustion relatively yields much lower amounts of poisonous carbon monoxide (that is very important in crowded cities), and it is also CO2-neutral in regards to the greenhouse effect. In comparison with gasoline, ethanol needs less amount of air for combustion, so the stoichiometric ratio for gasoline is 15:1, but for ethanol is 9:1. The burning velocity and flame structure of ethanol –air mixtures over a wide range of pressure and temperature have been studied using both a constant volume spherical and a cylindrical chamber with end windows. A thermodynamic model was used to calculate the burning velocity from the measured dynamic pressure rise in the spherical chamber. Photographic observations were made through the end windows in the cylindrical chamber. Smooth and cracked flames were all observed by using a highspeed camera.
