DETERMINATION OF OPTIMUM CONDITIONS FOR BIOREMEDIATION OF IMIDACLOPRID BY RHIZOBIUM PUSENSE STRAIN IHB 1(OP218458.1) AND PSYCHROBACTER CELER STRAIN IHB2(OP672320.1)
...Show More Authors

Imidacloprid (1-[(6-chloro-3-pyridinyl) methyl]-N-nitro-2-imidazolidinimine), is a recent systemic and contact insecticide with high activity against a wide range of pests. Continuous dispersion of this pesticide in the environment and its stability in soil results in environmental pollution which demands remediation. Used in this research Rhizobium pusense strain IHB 1 (OP218458.1) and Psychrobacter celer strain IHB2(OP672320.1). which were previously isolated from botanical fields soil of greenhouses which has been using imidacloprid pesticides for many years to determine optimum condition and degradation ability for imidacloprid by tested in minimal salt medium (MSM) for a duration of 21 days. The temperature, pH number, and concentration of the pesticide were determined for the growth of bacteria. The best growth of Psychrobacter celer strain IHB2(OP672320.1) was at 28°C, pH 6, and pesticide concentration 50ppm, while Rhizobium pusense strain IHB1 (OP218458.1) had the best growth at 24°C, pH 7, and pesticide concentration 75ppm.Levels of imidacloprid in MSM medium were analyzed by high-performance liquid chromatography (HPLC). Rhizobium pusense strain IHB 1 (OP218458.1) was able to degrade 50.2% and Psychrobacter celer strain IHB2(OP672320.1) was able to degrade 59.01% of the initial amount of imidacloprid at the concentration of 25 mg /L in MSM media. All bacteria introduced in this study were among the first reports of imidacloprid degrading isolates in MSM-limited media from greenhouse soil. Therefore, the results of this study demonstrate the effectiveness of using soil bacteria for microbial degradation of imidacloprid. These findings suggest that these strains may be promising candidates for bioremediation of imidacloprid-contaminated soils.

This research deals with the role that the media can play in spreading awareness, culture and sound behavior among members of society, due to its ability to reach the largest number of individuals; its wide spread within society; and the moral responsibility of the media in consolidating the components of civil peace. The media works on forming intellectual convictions and behavioral attitudes by publishing opinions and ideas, introducing them to people's awareness and enhancing them in the practice of their daily lives, he was its media medium. Sociologists and psychologists confirm that the media. The significance of the research comes due to the broadening of violence and sectarian fighting; the absence of a culture of civil social pe

Strength and Deformation of Concrete-Encased Grouting-Filled Steel Tubes Columns Exposed to Monotonic Quasi-Static Loading Conditions
...Show More Authors

This study aimed to evaluate the effectiveness of a novel concrete-encased column (CE) using small circular steel tubes filled with cementitious grouting material (GFST) as the primary reinforcement instead of traditional steel bars. The research involved three different types of reinforcement: conventional steel bars, concrete-filled steel tubes with 30% of the reinforcement ratio of steel bars, and concrete-filled steel tubes with the same reinforcement ratio as steel bars. Twenty-four circular concrete columns were tested and categorized into six groups based on the type of reinforcement employed. Each group comprised four columns, with one subjected to concentric axial load, two subjected to eccentric axial load (with eccentrici

Analysis the effect of economic conditions on the vegetative change in Baghdad using GIS and remote sensing techniques
...Show More Authors

The study of vegetative change of cities is one of the most important studies related to human life because of its direct correlation with the temporal conditions that occur. These include the economic problems that force people to move and look for job opportunities in the city, which leads to an increase in the population density of cities, especially for cities with an important economic and administrative location as in the capital city of Baghdad. In this study, the effect of the increasing in population density was analyzed on the urban planning of Baghdad city. The decreasing in vegetation was due to the increasing of urban areas on the outskirts of the city, which led to an increase in its area. Moreover, urban cities increased t

Multiple sclerosis (MS) is a chronic, inflammatory demyelinating disease of central nervous system with complex etiopathogenesis that impacts young adults (Lee et al., 2015), and MS impacts younger and middle aged character and leads to a range of disabilities that can alter their daily routines (Yara et al, 2010). Although, the exact cause of MS is still undetermined, the disease is mediated by adaptive immunity through the infiltration of T cells into the central nervous system (Bjelobaba et al, 2017). MS causes the Focal neurological symptomsand biochemical changes in the molecular level and the variation of neural cells such as loss or alteration of sensation, motor function, visible signs such as blurred vision or transient blindness,

Spectrophotometric Determination of Rantidine –HCl in Pharmaceutical Formulations
...Show More Authors

Spectrophotometric methods were developed for the determination of rantidine-HCl in pharmaceutical tablets. These methods were based on the reaction of DDQ and p-chloranil with rantidine-HCl, resulting in the formation of an orange-red and purple colored products which are quantified spectrophotometrically at 460 and 540nm in DDQ and p-chloranil, respectively. A graph of absorbance versus concentration show that Beer’s law is obeyed in a concentration ranges of 20-160 and (30-120)g/ml with molar absorptivities of 2.631 x 103 and 1.052 x 103 The optimum conditions for color development are described and the proposed methods were applied satisfactory to pharmaceutical preparations

Twosimple, sensitive,accurate, and precise spectrophotometric methods have been developed for the determination of chlorpromazine – HCl in pure form and pharmaceutical formulation. The first method involved treatment of cited drug with a measured excess of permanganate in acid medium and the unreacted oxidant was measured at 525 nm. The second method involves the reaction of the drug with potassium permanganate in the presence of sodium hydroxide to produce a bluish – green colored manganite which is measurable at 610nm. All the experimental variables affecting the development of the manganite ions were investigatedand conditions were optimized. Working linearity ranges were 5-45 µg.mL-1and 1-20 µg.mL-1 by two methods respectively. Th
