Abstract
With the increase in urbanization and degradation of the urban environment, sanitation is becoming a predominant challenge within the short run. High-resolution satellite imagery gives the first conception of polluted drainage sites, whether by the river or in residential areas. This helps in studying the seriousness of pollutants and their causes. The main objective of this research was to evaluate the pollutants in wastewaters received at pump stations in Al-Kut city in Wasit governorate, Iraq by using GIS data and techniques. . These were in addition to, evaluating the quality of sewer network in one of the highly polluted areas and propose the most suitable location for the establishment of a wastewater treatment unit. Collected three samples of water in the following months: February, March and April in 2017. Samples were analyzed for (BOD, COD, PO4-, NO2-, NO3-, TDS, TSS, H2S, and EC). The spatial distribution of these pollutants within the studied area was carried out using Ordinary Kriging (OK). The results revealed an increase in the concentrations of the studied pollutants when compared with Iraqi standards. The mean concentrations were: 247.54, 8.96, 0.59, 2.92, 1557.58, 232.79, 21.55, 2164.58, and 283.63 mg l-1 for BOD, PO4-, NO2-, NO3-, TDS, TSS, H2S, EC and COD, respectively.The results revealed that the sewer network in Al-Anwar area complies with the international standards regarding to pipe slopes and flow velocity. Finally, a multi-criteria model was also used to propose the most suitable location for the establishment of a treatment unit in Al-Kut city. That model took into account the type of land use, wind direction, and proximity to main sewer lines, main streets, electricity lines and residential areas. It was found that the location in the east side of the city has the best conditions for establishing that waste water treatment unit.

Abstract The problem of the research on the number of phenomena that resulted from the survey study in both office and field, and the most important of these phenomena low level of production processes and there are lost and damaged ratios, and the company faces strong foreign competition. The importance of the study stems from two aspects، one of which is related to the presentation of an intellectual framework for the variables it addresses (knowledge management, organizational creativity). This study will contribute to enriching these variables and the other practical ones related to the researcher's understanding of the importance of knowledge management in organizational creativity. These companies develop these companies for multiple purposes including the desire to go global. The study group also consisted of Diyala, and the category of the inquisitors was included in the managers and employees of the company. The research on the study hypothesis was based on the design and testing of a specially designed survey list. The list included two parts. The first part dealt with knowledge management. The second part includes organizational creativity. The second chapter deals with the conceptual framework for knowledge management and organizational creativity, while the third chapter deals with the field study and statistical analysis of the data. The fourth chapter discusses the results of the field study and the recommendations.

Abstract The aim of the present study is to know the water specification which ejected from Al-Kut sewage treatment plants in the Tigris River the main great river in Iraq and going through Al- Kut City the center of Wasit Province. It is located 32.516 latitude and 45.847 longitudes, and it is situated at elevation 22 meters above sea level. Four sewage treatment plants stations were selected in Al-Kut City, Bimonthly sampling was carried out from January 2018 till December 2018; two samples were taken each month. Station one was AL-zahraa plants. The second station was Dawr aleummal plants, the third station is Aleiza plants and the four stations is ALfalahia plants. In the present study twenty-eight physical and chemical parameters were selected on the importance of these parameters. These parameters are ranged as follows: COD 98 to 360 mg/L, water temperature 13.3 to 34 ºC, EC 1337 to 3800 µS/cm H2S 9 to 81 mg/L, TDS 800 to 2450 g/L, NO2 = ND to 0.9 mg/L ,TSS 40 to 560 mg/L, pH 7 to 8.1 , NH3 22 to 95 mg/L، BOD5 53 to 318 mg/L، Cl- 153 to 447 mg/L, Sulfate 125 to 987 mg/L, NO3 -2 ND to 9 mg/L PO4 -2 ND to 19.5 mg/L. Concluded from the current study, all wastewater treatment has a direct impact on the water characteristics of the Tigris River.

Abstract: The study aims to achieve the best returns, particularly, the volatility of prices for financial assets. We will attempt to find a way to determine the best buying and selling when the price of the asset is subject to mean- reverting model. This model deals with the price that balance and stationarity. We will use stochastic and numerical algorithm to get the best price for buying and selling. The sample of the study (hotels, industry, communications), which includes (8) companies listed in the Iraqi market selected for the period (1/1 / 2015-30 / 6/2018). To make the hypotheses of the study, the two statistical programs (R Maple) were used. The study resulted in several conclusions: The random algorithm used in our study is a method that does not need to determine the distribution of the price variable. The advantages of prices using the random algorithm are relatively less than the price advantages using the numerical algorithm. This is what distinguishes the random algorithm. The few benefits indicate that the financial market is balanced and efficient and that prices are subject to market mechanism and supply and demand forces In it, in light of this Conclusions reached a set of recommendations including: the adoption of random algorithm in the Iraqi market for securities because they achieved a reasonable profit margin and ease of implementation by the dealers and researchers because they rely on the daily stock price only.

ABSTRACT The continuation emergence of multidrug resistant bacterial infections and the decline in discovery of new antibiotics are main challenges for health care throughout the world. Recently, chemically and biologically synthesis nanoparticles are used as new antimicrobial agents. Present study focused on detection antimicrobial action of biosynthesis nanoparticles versus chemically synthesis nanoparticles on bacterial infections in Lab. Method: in this study, zinc oxide nanoparticles (ZnONPs) and silver nanoparticles (AgNPs) are produced from zinc nitrate and silver nitrate respectively by chemical and biological methods. One concentrations of metallic nanoparticles (60ppm) are tested against salmonella typhi (S. typhi), Pseudomonas aeruginosa (P. aeruginosa), Streptococcus pneumonia (S. pneumonia) and Streptococcus aureus (S. aureus) by disc diffusion method. Result: biologically synthesis AgNPs more effected on bacterial species (especially on S. pneumonia) than biologically synthesis ZnONPs, chemically synthesis ZnONPs and chemically synthesis AgNPs. On other hand biologically synthesis ZnONPs more effected than chemically synthesis ZnONPs on bacterial species especially S. pneumonia. Conclusion: biologically synthesis nanoparticles more effected on tested bacterial species especially S. pneumonia then chemically synthesis nanoparticles. Biologically synthesis AgNPs are an excellent antimicrobial agent.

Abstract
Abstract: The electronic spectra within UV‌‌-Vis region for benzene (C6H6) and Carbone tetrachloride (CCl4) molecules have been studied. Since Benzene molecule belongs to D6h point group, with very high symmetry elements, therefore it may be expected for its internal vibrations to be either infrared or Raman active only. The spectral properties of (CCl4) are also have been studied. This (CCl4) belongs to Td point group, where its fundamental internal vibrations will be also, infrared or Raman actives. These aspects will be considered and discussed in this work.
