A Study on Transportation Models in Their Minimum and Maximum Values with Applications of Real Data

The purpose of this paper is to apply different transportation models in their minimum and maximum values by finding starting basic feasible solution and finding the optimal solution. The requirements of transportation models were presented with one of their applications in the case of minimizing the objective function, which was conducted by the researcher as real data, which took place one month in 2015, in one of the poultry farms for the production of eggs in the governorate of Ajlun- Jordan, where the eggs were stored in three stores until marketed to four markets. A suggested method was also presented in case of maximizing the objective function based on the use of the Minimax rule. In the first step, it determines the maximum marginal profit for each row and column, and then selects the smallest marginal profit between rows or columns until the rest next steps. This method used the costs used for real data in poultry farms to find marginal profits.                                                                                                                      

The most important results of starting basic feasible solution, is that Vogel's method was less total cost(3400) JD when compared with north west corner method and least cost method .                      

 In the optimal solution, MODI method was used for Vogel's method and other methods, where positive or negative values ​​were obtained for all costs or profits of the non-basic variables. The total profit of the proposed method in this paper is equal to the results of the different methods amounting to (20600) JD.

The efficiency calibration for local manufacturing gamma scanning systems of radioactive waste drums

The Local manufacturing scanning gamma system designed in Tuwaitha site for nondestructive assay method of radioactive waste drums, where it consist of two main parts with their belongings for controlling the of detector and drum movements up-down and rotation respectively. The volume of the used drum is 220 L with 85 cm height. The drum filled with Portland cement. Six cylindrical holes were made within cement drum and distributed in radial arrangement.The152Eu source inserted in these holes individually, to measure the average angular count rate of gamma radiation. The full energy efficiency value for geometry of drum and detector is computed for thirteen photo peaks. The average efficiency represented by the curve of these peaks indic

Hydrogeochemistry of the Umm er Radhuma Unconfined Aquifer, Western Desert Iraq- Saudi border

      The Umm Er Radhuma unconfined aquifer Hydrogeochemistry in the Saudi – Iraq border desert was studied to identify the main hydrogeochemical processes and rock-water interaction. The measurements were done using standard APHA procedures. The results indicated that Na+ and Cl- are the dominant ions in the groundwater. The average contribution of cations in the aquifer is Na+ + K+ ( 26 %), Ca2+ (14 %), and Mg2+ (10%) ; whereas anions contribution is Cl- (24 %) , SO42- (20 %), and HCO3- (6 %).  The results reflect that the examined water is hard water of neutral to slightly alkaline, slightly brackish, with m

Using Spatial Analysis Methods to Evaluate the Soil Contamination of Baghdad City, Iraq
Abstract<p>The current study aims to identify soil pollutants from heavy metals The study utilized 40 topsoil (5 cm) samples, which adapted and divided into seven regions lies in Baghdad governorate, included (Al-Husainya,(Hs) Al-Doura (Do), Sharie Al-Matar (SM), Al-Waziria (Wz), Nharawan (Nh), Abu Ghraib (Abu) and Al-Mahmoodyia (Mh)). Spatial distribution maps of Nickel (Ni), Manganese (Mn), Lead (Pb) and Zinc (Zn) were created for Baghdad city using Geographic Information Systems (GIS). The concentrations of four heavy metals in the soil of different area of Baghdad were measured and observed using XRF instrument.

Extracellular Enzyme of Endophytic Fungi Isolated from Ziziphus spina Leaves as Medicinal Plant

Endophytic fungi live inside plants or any part of them without creating any visible pathogenic signs. Endophytic fungi are found within medicinal plants and have shown strong biologic activity, such as anticancer and antioxidant activities, as well as producing extracellular enzymes. In this study, different fungal strains were isolated from the leaves of the medicinal plant Ziziphus spina, including Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Cladosporium sp., Rhizopus sp., and Mucor sp. Extracellular enzymes have been quantified using agar plate-based methods in which fungi were grown in specified growth media to detect the enzymes produced. The results showed that A. niger has the highest ability to produce amy
