For this purpose, monthly samples were collected for a period of six months from October 2023 until March 2024, the first station (before treatment) represents the water coming out of the crude oil filter units. As for the second station (after treatment) it is located in the refinery waste treatment unit, the site represents the treated water. many physical and chemical tests were conducted on water, they ranged of temperature values ​​before the treatment ranged between (17-33) compared to its value after the treatment (15-31), and the electrical conductivity values ​​before the treatment ranged between (295-405)µS/cm, while after the treatment it was (349-471)µS/cm.

The objective of this study is to measure the genetic expression of Geh gene responsible for producing the lipase enzyme from <em>S. aureus </em>isolated from acne patients. This study was conducted by collecting 130 swabs from acne patients at Tikrit Teaching Hospital. Using routine bacterial isolation and identification methods, 50 samples (38.4%) of the total samples were identified as <em>S. aureus </em>through its ability to grow in mannitol salt agar medium, the fermentation of mannitol sugar, and the change of the medium color to yellow. The <em>Geh</em> gene expression of ten <em>S. aureus</em> isolates from acne patients was examined using RT-PCR. The results showed that <em>Geh</em> gene was expressed in all isolates, with an expression ranging from 1.5 to 7.2, and that the mean folding of the <em>Geh</em> gene for ten samples was 4.2. This indicates the presence of high gene expression of the <em>Geh</em> gene in <em>S. aureus</em> isolates. Therefore, it is concluded that Lipase enzyme plays an important role in the pathogenesis of <em>S. aureus</em> in acne patients. </p> 2024-10-25T00:00:00+02:00 Copyright (c) 2024 THIS IS AN OPEN ACCESS ARTICLE UNDER THE CC BY LICENSE http://creativecommons.org/licenses/by/4.0/ https://tjps.tu.edu.iq/index.php/tjps/article/view/1664 T Kinetic and thermodynamic study of the adsorption isotherm of methylene blue dye from aqueous solutions by activated carbon 2024-07-14T05:33:19+02:00 Asraa Fawzy Mustafa Altikrite ahshynab@student.daei.org <p>The efficiency of activated carbon in wastewater as a powerful blue dye remover has been studied. In this work, activated carbon manufactured from Sidr leaves was used to adsorb methylene blue dye. The factors affecting adsorption were studied, such as the weight of the adsorbent, temperature, contact time, and initial concentration of the dye, and the optimal conditions for adsorption were determined according to the experimental results. It was evident from the experimental results obtained that the removal efficiency increases with the increase of both the weight of the adsorbent material and the contact time. It was observed that the adsorption process was possible, spontaneous, and exothermic in the temperature range (293-333 K), and this is what determined the thermodynamic variables ΔG°, ΔH°, and ΔS°. The Langmuir, Freundlich, and Timken isotherms were used to examine the experimental equilibrium data. To follow the adsorption process, two logical models were chosen, represented by the Elovage equation and diffusion.</p> 2024-10-25T00:00:00+02:00 Copyright (c) 2024 THIS IS AN OPEN ACCESS ARTICLE UNDER THE CC BY LICENSE http://creativecommons.org/licenses/by/4.0/ https://tjps.tu.edu.iq/index.php/tjps/article/view/1676 Effect of Chloride Solution on Liquid Limit, and Plasticity Index of Soil in Selected Sites in Erbil /North Iraq 2024-08-07T08:16:05+02:00 Nadhmia Najmaddin Majeed nadhmia.majeed@su.edu.krd <p>This study is an attempt to investigate the effect of NaCl, CaCl<sub>2</sub>, KCl, and NH<sub>4</sub>Cl solutions with different concentrations (2.5%, 5%, 7.5%) on the liquid limit, plastic limit, and plasticity index of Sarbasty and Mamwastayan soil samples /Erbil Governorate. The soil samples' liquid and plastic limits were found by using the cone penetrometer method. The Results showed that the soil's liquid, plastic limits, and Plasticity index decreased with increasing salt solution concentration. Maximum reduction of liquid limit and plastic limit in Sarbasty was from 53.6 to 34.3 and in Mamwastayan from 35.9 to 27.2, both accomplished by adding a concentration of 7.5% of KCl and CaCl<sub>2 </sub>respectively. According to the Unified Soil Classification System, the Sarbasty soils were classified as high plasticity clay (CH), and Mamwastayan low plasticity clay (CL). After adding different concentrations of salt solution to the soil, the Sarbasty soil classification changed from CH to CL. Mineralogically these soils are composed of non-clay minerals of calcite and quartz and clay minerals consisting of Montmorillonite, Chlorite, swelling Chlorite, Kaolinite, Illite, Palygorskite, and Illite- Chlorite. Sarbasty soil was the most effective salt chloride solution than the Mamwastayan soil sample swelling.</p> 2024-10-25T00:00:00+02:00 Copyright (c) 2024 THIS IS AN OPEN ACCESS ARTICLE UNDER THE CC BY LICENSE http://creativecommons.org/licenses/by/4.0/ https://tjps.tu.edu.iq/index.php/tjps/article/view/1648 Study The Effect of Doping Zinc Oxide Thin Films With (0.5 wt. %) Carbon Nanotubes by Vacuum Evaporation 2024-07-02T18:02:49+02:00 ahmed mansoor ms230031pep@st.tu.edu Walla Mohammd Wlla.mahphod@tu.edu.iq <p>The study included the production of nano-thin films made of zinc oxide doped with carbon nanotubes (ZnO:CNTs) at a doping ratio of 0.5 wt%. The materials are applied onto glass substrates using the vacuum evaporation process. The structural characteristics of the thin films of undiluted and doped ZnO were assessed using X-ray diffraction (XRD). Additionally, the surface properties of the films were examined using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The optical characteristics of the thin films were analyzed and described using UV-Vis spectroscopy. The ZnO thin films exhibited crystalline formations. The thin films exhibited significant orientations along the (100), (002), and (101) crystallographic planes, indicating their hexagonal phase structures. The crystal size of ZnO thin films exhibited a range of 30.87 nm to 19.96 nm after the process of doping. The study findings demonstrate that the addition of carbon nanotubes leads to an increase in the absorption ratio. Zinc-doped carbon nanotube thin films has features that make them suitable for many applications, such as gas detectors and UV detectors.</p> 2024-10-25T00:00:00+02:00 Copyright (c) 2024 THIS IS AN OPEN ACCESS ARTICLE UNDER THE CC BY LICENSE http://creativecommons.org/licenses/by/4.0/
