A simple spectrophotometric method for the determination of trimethoprim (TMP) in pure form and in its pharmaceutical formulation has been described. The method is based on the reaction of TMP with 2,4-dinitro-1-fluorobenzene reagent (DNFB) in acetone medium to give a highly rosy red colored product with maximum absorption at 538 nm with a molar ratio of 1:1. Beer's law is obeyed in the range 10-75 μg/ml with molar absorptivity of 1.917x103 l.mol-1.cm-1 and Sandell's sensitivity of 0.1514 µg/cm2. Precision (RSD) better than 1.7 % and accuracy (average recovery %) is 100.76 %. The suggested method has been applied to dosage forms as tablets and compared with the pharmacopoeial method, t-test is evaluated and found 1.828 at 95% confidence limit. The results show that there is no interference are present in commercial dosage forms.

Journal of Education and Science, 2011, Volume 24, Issue 2, Pages 79-88
DOI: 10.33899/edusj.1999.58726

In this paper, a new adapted optimal step-size is designed to improve the efficiency of pair conjugate method. At each linear search an acceptable step- size is estimated during quadratic interpolation and this estimate is used as an initial trial step-size. The technique needs only additional gradient evaluation at each search direction. Also we have improved Armijo line search technique to be used together with the new optimal stepsize.
The numerical results are more efficient than the results of the same method using the classical scheme for the linear search technique.

Since the mid of 1990th, Mosul city over all Iraq cities, is used widely the local power diesel generators. The generators exhaust emits a large amounts of hydrocarbon gases, including, of course, carbon dioxide. In most cases, the Purity of the fuel (gas oil) is below the accepted standard purity. Certainly, the emission of large quantities of such hydrocarbon gases to the atmosphere, play an important role in contributing to global warming. Therefore, a significant bad side-effects influence Mosul city thermal balance and climate changes.
Because the studied area is surrounded by Hills and highlands, therefore this topographic terrain leads to the precipitation of the exhaust generator output pollutants within the city air space, and leads to increase climate change which is reduce the green area proportion (i. e.; increasing the dryland spaces).
Unfortunately, large proportions of local forest trees in the studied area, have been subjected to logging operations by citizens under the current circumstances for use as fuel.
In this study, some treatments have been suggested to reduce further pollution emitting from the diesel generators. The aim is to reduce their negative effects on the environment, human health and land use. GIS software have been adopted in the current study (Global Mapper9, ArcGIS9.1) process and analyze the DEM data of the studied area with respect to satellite image to show the topographical features of the area and the location of the generators. GIS software also have been applied in the georeferncing process of the adopted remote sensing data.
The descriptive approach has been adopted in the completion stages of the study in addition to the available data
