A field Experiment was carried out in Baghdad for the purpose of compare five horticulture machines during used two types of fuel deffirance in octane number, normal and super fuel which produced in Iraqi and measuring the vibrations transmitted of the three axes are longitudinal X , lateral Y and vertical Z from handlebar in (Mowers) to the operator which walks behind the mower, and the determine of the productivity practical of cutting, productivity passing and fuel consumption. Experiment Factorial used with two factors, The first factor was Five Mowers vary in width , types, weight and company manufacturer, The Second factor was the types of fuel used internal combination engine horticulture mowers were Normal fuel with Octane Number 82 and super fuel with Octane Number 95, according to randomized complete block design were used in this experiment with three replication . Least Significant Design (LSD) 0.05 was used to compare the mean of treatments. The result showed mower A type John Deer recorded the lowest vibration values in longitudinal, lateral, vertical and resultant whole vibration 5.21, 2.55, 3.85 and 6.97 m/sec² , higher productivity practical cutting 1160 m²/hr, higher productivity passing 128 kg/donam and least fuel consumption 1.378 L/donam. Super fuel recorded lowest longitudinal, lateral, vertical and resultant whole vibrations 4.63, 2.53, 3.86 and 6.54 m/sec², higher productivity practical cutting 1045 m²/hr and least fuel consumption 1.446 L/donam. The Result in the five mowers exceeded the legislated permissible vibration exposure limits in the worldwide.
A pots experiment was conducted in the plastic house of Kalar Horticulture station Province of Sulaimania, by using soil brought from one of Kalar region fields during growing season of 2007-2008, to study the effect of increasing levels of urea fertilizer which is (0, 0.20,0.40,0.80) g/pot which equals to (0,100,200,400) kg urea/ha, and super phosphate fertilizer which is (0,0.24,0.48)gm/pot which is equal (0,120,240) kg sup/ha, in nutrition state of wheat IPA 95 component, clay determining Nitrogen, Phosphor and Potassium content in green part and seeds. The Completely Randomized Design was used with three replication per t
... Show MoreA numerical simulation is made on the thermal lensing effect in an laser diode end-pumped Nd:YAG laser rod. Based on finite element method (FEM), the laser rod temperature distribution is calculated and the focal length is deduced for a Gaussian and super-Gaussian pump beam profiles.
At the pump power of 20W, the highest temperature located at the center of end-pumped face was 345K, and the thermal lens focal length was 81.4mm along the x-z axis.
The results indicate that the thermal lensing effect sensitively depend on the pump power, waist radius of the pump beam and the pump distribution in a laser rod geometry.

Ibn al-Haytham is the pioneer of optics, which is a science that had described optics circumstances. Optics or landscape science as it was known by the Arab and Muslim scientists at the time when is a science known as the conditions of sighters in their quantity and quality as the proximity and distance from the beholder , the different forms , conditions and what mediate between the beholder and the microscopes , to explain useful knowledge of what obscures the sight of the conditions of sighters and is used to measure the space Distant criminality and mirrors.

Objectives: This study aims to explore the efficiency of renal system functions as indicated by renal function tests and electrolyte levels among bladder cancer patients.
Methods: All patients in this case-control study were recruited from Ghazi Al-Hariri Hospital for surgical specialties in Baghdad during the period from December 2021 to June 2022. A total of 100 individuals were enrolled in this study and divided into two groups.

This paper aims at presenting a comparison between objective and subjective tests . This paper attemptsto shed light on these two aspects of tests and make do a compression by using suitable techniques for objective and subjective tests .
The paper compares between the two techniques used by the objective and subjective tests respectively, the time and efforts required by each type, the extent to which each type can be reliable, and the skills each type is suitable to measure.
The paper shows that objective tests, on the contrary of the subjective ones, encourages guess> Objective tests are used to test specific areas of langua
