Abstract Asthma is a complex disease defined by chronic airway inflammation and airflow limitation causing variable respiratory symptoms which include shortness of breath (SOB), wheezing, chest tightness and cough. Asthma guidelines advocate adding a second long acting bronchodilator to medium doses of inhaled corticosteroids (ICS) rather using high doses of ICS alone to control moderate to severe persistent asthma. The aim of this study was to evaluate the clinical outcomes of three medication regimens indicated for Iraqi patients suffering from persistent asthma. This study was interventional randomized clinical study conducted on a sample of adult Iraqi asthmatic patients in Baghdad City. The study composed of three visits distributed over eight weeks; baseline visit followed by first follow up and second follow up visits after four and eight weeks respectively. The study enrolled 78 adult patients with moderate to severe persistent asthma as diagnosed by specialist physician according to patient history and baseline pulmonary function test (PFT) and allocated them randomly to three groups (each group included 26 patients) to receive equivalent medium doses of budesonide inhaler in addition to either formoterol inhaler, oral modified release aminophylline tablets or tiotropium inhaler (first, second and third group respectively). Sixty four patients completed this study. The mean ages of patients were above 35 years with slightly more male predominance. The study groups developed significant increase of peak expiratory flow rate (PEFR) and forced vital capacity (FVC) values at the first follow up visit compared to baseline values (p<0.001). Thereafter, the first and third groups achieved significant higher values at the second follow up visit compared to first follow up visit (p<0.001), while second group produced no change. All the groups developed significant improvement of Mini asthma quality of life questionnaire (MiniAQLQ) scores and percentage of symptom free days (SFD) at first follow up visit and continued further significant improvement at the second follow up visit (p<0.001). Generally, between groups comparison according to extent of change of study parameters revealed that third group produced the greatest improvement over the entire study period followed by the first group, whereas the second group was associated with the least extent of improvement. This study concluded that all groups caused significant improvement in study parameters compared to baseline values and also concluded that the third group of inhaled [tiotropium/budesonide] was associated with the highest extent of improvement followed by first group, while the second group was the least.
Agricultural companies could push investment forward and help in production base variation and developing production techniques. They also play a significant role in organizing and providing requirements of market economy. This work aimed at studying economic efficiency of the six agricultural companies that are registered at Iraqi stock market for the period 2005-2016. Capital of these companies was between (300 million-7.5 billion IQD). Several financial analysis indicators were applied such as activity percentages. Average of capital circulation was 0.91 for private company of agricultural production، and lowest share was for Iraqi company for producing and marketing field crops. Assets average circulation was highest for the pr

requirements in the recent development in the automobile industry. The main engine control
input that satisfies the above requirements is the throttling angle which adjusts the air mass
flow rate to the engine port. Due to the uncertainty and the presence of the nonlinear
components in its dynamical model, the sliding mode control theory is utilized in this work
for the throttle valve angle control system to design a robust controller for this system in the

In this paper, a new equivalent lumped parameter model is proposed for describing the vibration of beams under the moving load effect. Also, an analytical formula for calculating such vibration for low-speed loads is presented. Furthermore, a MATLAB/Simulink model is introduced to give a simple and accurate solution that can be used to design beams subjected to any moving loads, i.e., loads of any magnitude and speed. In general, the proposed Simulink model can be used much easier than the alternative FEM software, which is usually used in designing such beams. The obtained results from the analytical formula and the proposed Simulink model were compared with those obtained from Ansys R19.0, and very good agreement has been shown. I

Show MoreResearchers classified deconstruction as a strategy concerned with reading the philosophical, literary, artistic and critical texts according to (construction and deconstruction) binarism, which is an applied procedural space that calls for researching the layers of meaning and its non-closure. It establishes reversals in the text level. The center changes into a margin and vice versa. Thus the two researchers sought to study the deconstruction strategy and its work in the theatre field, that deconstruction is considered one of the most important modern currents that actively inters in reading the theatre show. The research studies the procedure of the construction and deconstruction of the Iraqi theatre actor reg
