This study describes the determination of some phenols in four different zones of Tigris river in Iraq including, AL-Krieat, AL-Kadhimiya, AL-Jadiriyah, and AL-Adhamiyah. The phenolic compounds analyzed were (2,3-dimethylphenol, 4-chlorophenol, 3-nitrophenol and 2,4-dinitrophenol) using reverse phase high performance liquid chromatography (RPHPLC) with a UV detector on ODS-C18 column(150×4.6 mm I.D) and a mobile phase consisted of methanol-water(30:70)%(v/v) at pH 5.0, and a column temperature at 30C° with 20 µL injection. UV detection helps to identify different phenols at wave length at 280 nm with a flow rate at 0.5 ml/min. The separation time was (< 6) min.The results indicated that the AL-Adhamiyah zone contains the highest concentration of 3-nitrophenol (0.094 µg/mL), while the AL-Jadiriyah zone recorded the lowest concentration of 3-nitrophenol (0.056 µg/mL).On the other hand the other phenolic compounds studied did not record any concentration in four zones of Tigris river. The values of correlation coefficient and accuracy were calculated for 3-nitrophenol, the graph was linear with very good correlation coefficient (R2>0.9999).
The environmental references represented by the intellectual, social, economic, political and religious pressures are considered fundamental factors for the artistic achievement whose importance comes from their multiplicity and branching into natural and psychological pressures that affect the multiplicity, diversity and variability of the artistic and performative methods. Thus they determine the artist's orientations and the creative artistic visions are summoned through symbols and semantic signs of the visual surface, because the societal thought in art in general and the fine art in specific occupies an influential position
... Show MorePetrophysical properties evaluation from well log analysis has always been crucial for the identification and assessment of hydrocarbon bearing zones. East Baghdad field is located 10 km east of Baghdad city, where the southern area includes the two southern portions of the field, Khasib formation is the main reservoir of East Baghdad oil field.
In this paper, well log data of nine wells have been environmentally corrected, where the corrected data used to determine lithology, shale volume, porosity, and water saturation. Lithology identified by two methods; neutron-density and M-N matrix plots, while the shale volume estimated by single shale indicator and dual shale indicator, The porosity is calculated from the three common po

Two methods have been used to calculate the lateral carrying capacity of piles foundation; the first one is two-line slopes intersection method (TLSI) and the second method is a modified model of soil degradation. The model proposed by Heerama and then developed by Smith has been modified to take into consideration the effects of heavy loads and soil contamination. The ultimate lateral carrying capacity of single pile and piles group (2×2) driven into samples of contaminated clayey soils have been calculated by using the two methods. Clayey soil samples are contami

P. aeruginosa has a well-known biofilm forming ability. The expression of polysaccharide encoding locus (pelA gene) by P. aeruginosa is essential for this ability. The purpose of the current research was to determine the biofilm formation in P. aeruginosa isolated from clinical samples and to evaluate the role of the selected PelA gene in biofilm formation using PCR method in Iraqi patients. Results revealed that 24 (96%) isolates were found to have the ability to form biofilm that was remarkably related to gentamicin resistance. Moreover, the pelA gene was found in all biofilm-producers. In c

Three land cover indices are used which are the Normalized Difference Vegetation Index, Normalized Multi-Band Drought Index and the top of atmosphere surface temperature to build a fuzzy decision about the desertification degree using eight decision roles. The study covers a temporal period of 38 years, where about every 10 years a sample is elected to verify the desertification status of the region, starting from 1990 to 2018. The results show that the desertification status varied every 10 years, wherein 2000 encountered the highest desertification in the south-west of Iraq.
This study aims at shedding light on the linguistic significance of collocation networks in the academic writing context. Following Firth’s principle “You shall know a word by the company it keeps.” The study intends to examine three selected nodes (i.e. research, study, and paper) shared collocations in an academic context. This is achieved by using the corpus linguistic tool; GraphColl in #LancsBox software version 5 which was announced in June 2020 in analyzing selected nodes. The study focuses on academic writing of two corpora which were designed and collected especially to serve the purpose of the study. The corpora consist of a collection of abstracts extracted from two different academic journals that publish for writ

Show MoreThe study analyzed the current situation of public hospitals in the capital of Baghdad exclusively and diagnosed the resources available; especially after the high demand for these hospitals as a result of the citizen’s need to review the hospital to take care of them, especially after the Corona pandemic. Eight major hospitals in Baghdad were selected to determine the current reality of providing fire safety tools or equipment and what are the preventive measures needed to reduce it. The results after practical study showed many defects and weaknesses in the current situation due to their reliance on the traditional management to manage and provide all preventive measures and safet
Psoriasis is one of the skin’s chronic inflammatory diseases. Psoriasis etiology isn’t exactly known. Recently, it has been suggested that the imbalances in oxidant-antioxidant status happening because of the increase in reactive oxygen species production (ROS) and/or deficient function regarding the antioxidant system might be included in psoriasis pathogenesis. The major goal is to evaluate the antioxidant defense status in patients experiencing psoriasis and oxidative stresses represented by malondialdehyde (MDA) level and evaluate liver enzymes and vitamin D3. There are some tests of biochemical parameters and vitamins (GSH, MDA, VitD3, SOD, GPx, CAT, AST, ALT, and ALP) are conducted on 35 patients experiencing psoriasi
