By comparing important indicators to World Health Organization (WHO) criteria, this study aims to analyze the river's water quality. It focuses on detection of cadmium (Cd), lead (Pb), nickel (Ni), arsenic (As), mercury (Hg), iron (Fe), and cobalt (Co). Fifteen samples of the Tigris River near the Al-Dura project of water remediation were obtained and cultured on selective media, and the water quality parameters, like TSS, TDS, TH, pH, turbidity, EC, BOD, COD, OD, TOC, and heavy metals, were estimated. Bacterial DNA was extracted, then efflux genes were detected with the presence of heavy metals in the tested samples. Results illustrated that K. pneumoniae gave positive results in nine of the total fifteen samples, and the water quality parameters were within the normal ranges, except for elevated levels of DO and TOC, and decreased levels of BOD and COD, with a significant relationship among heavy metal levels with both AcrAB and OqxA genes at a significance level of p ≤ 0.05.","PeriodicalId":14665,"journal":{"name":"Iraqi Journal of Industrial Research","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141341335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary driver of COVID-19 severity and mortality is the cytokine inflammatory storm. Elevated levels of ferritin, resulting from this storm and secondary hemophagocyticlymphohistiocytosis, have been observed in severe COVID-19 patients. The cytokine storm represents an uncontrolled and dysfunctional immune response within the pathogenic mechanism of COVID-19, leading to acute respiratory distress syndrome (ARDS) and systemic organ failure. Ferritin, an iron storage protein crucial for regulating cellular oxygen metabolism, shows a significant correlation with disease severity in COVID-19 patients.This study, conducted across three Libyan hospitals and two private laboratories from 2018 to 2022, targeted 500 cases to investigate ferritin's role in COVID‐19. Polymerase Chain Reaction (PCR) tests confirmed COVID-19 positivity. Ferritin levels were measured using a fully automatic device, revealing high levels in almost all positive cases, with some experiencing levels as high as 4532 ng/ml. Analysis of 209 negative COVID-19 cases before and after the pandemic showed consistently low or normal ferritin levels. Among the positive cases, 250 were admitted to the ICU, with a significant proportion experiencing elevated ferritin levels, and 82 ICU patients succumbed to the disease. Gender and age did not seem to influence ferritin elevation in COVID-19 cases.In conclusion, increased ferritin levels may indicate worsening COVID-19 cases and could be associated with disease severity and mortality.","PeriodicalId":14665,"journal":{"name":"Iraqi Journal of Industrial Research","volume":"30 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141338774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, a direct correlation has been established between the duration of chemical etching and the resultant silicon nanowire's (SN) length, irrespective of the total etching time. The research encompasses an exploration of various spectral phenomena, including total and specular infrared (IR) reflection, Raman scattering (RS) of light generated by WHs, photoluminescence (PL) spectra, and more. Remarkably, the study reveals a noteworthy linear relationship between the duration of chemical etching and the length of the silicon nanowires. Furthermore, our investigation into diverse spectral phenomena, such as total and specular infrared (IR) reflection, Raman scattering (RS) from light generated by WHs, and photoluminescence (PL) spectra, elucidates intriguing patterns.

The primary research problem was to assess the manufacturing process's stability and capability to consistently produce conical filters that meet required specifications. The study followed a sample-based approach, where twenty samples, each containing four observations, were collected continuously over a period of seven days. For each sample, the mean (X ̅) and range (R) were calculated. The mean X-Double bar of 319.32 and the average range R-bar of 0.848 were obtained through data analysis. The main findings revealed that, on average, the manufacturing process was relatively close to the target value (X-Double bar = 319.32). However, the presence of several data points outside the control limits indicated potential variability in the process. The average range (R-bar = 0.848) highlighted certain variations in the manufacturing process, which might contribute to issues like damaged or re-worked production. The study identified the need for further investigation to determine the root causes of these variations, which could include machine malfunctions, material fluctuations, or operator errors. By addressing these concerns and reducing process variability, the factory can enhance product quality, decrease waste, and improve customer satisfaction. In conclusion, continuous process monitoring and improvement initiatives, such as Six Sigma, are essential for achieving greater process capability in conical filter manufacturing. This research contributes valuable insights into process performance and provides a basis for implementing corrective actions to ensure consistent product quality and meet customer demands.","PeriodicalId":14665,"journal":{"name":"Iraqi Journal of Industrial Research","volume":"56 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138975047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advantages of laboratory control include accuracy of measurement and the radionuclide composition of the primary coolant, measured using high-precision laboratory equipment. Instrumental spectra were obtained for the detection units BDKG-205m with various options for the placement of waste in a container, their composition, mass of waste, average density, and various activity levels of waste. The basic idea behind gamma-ray spectroscopy is to detect and analyze the energy of incident gamma rays. Gamma rays of varying energy and intensity are emitted from radioactive sources. The gamma-ray energy spectrum is produced when gamma rays are detected and examined using a spectroscopy instrument. The initial stage in gamma-ray spectroscopy is to detect gamma rays using a suitable detector. The detector captures and measures the energy of incoming gamma rays. Scintillation detectors, semiconductor detectors, and gas-filled detectors are among the detectors used in gamma-ray spectroscopy. The incoming gamma-ray energy is converted into electrical signals that can be processed and studied by these detectors. The spectroscopic system measures and records the energy of gamma rays when they are detected. The derived energy spectrum depicts the intensity distribution of gamma rays as a function of energy. The spectrum is a visual representation of the different energy levels found in gamma-ray emission.","PeriodicalId":14665,"journal":{"name":"Iraqi Journal of Industrial Research","volume":"1974 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138973973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, the TiO2 films were annealed for 2 hours at a temperature of 400 °C.

In addition, FESEM analysis showed a granular morphology that showed a tendency for fragmentation into smaller particles with the growth of the thickness of the sample. The thickness of the thin films was determined using the FESEM cross-section, and the results showed that the thicknesses were 278.01, 1630.53, and 2579.66 nm for TiO2 at laser energy of 700, 800, and 900 mJ, respectively. As the laser energy increased, the results showed an increase in the thickness of the thin film. In addition, the absorbance increased while the transmittance decreased with increasing thin film thickness.

Compared to the heterogenous Fenton process with ultraviolet irradiation, it increased oxidation and was affected by catalyst load, power of hydrogen pH, hydrogen peroxide amounts, and temperature. The findings showed that the iron-doped zeolite catalyst, pH, and temperature significantly degraded the chemical oxygen demand.

Most of the studies aim to find alternative natural materials to replace the carcinogenic chemical adhesives. A mixture of natural materials that are available in abundance, cheap in price and are resistant to water and heat, the failure of the interface between two solid dielectrics is a major source of insulation system failure, hence it is crucial to understand the principles regulating this breakdown occurrence. It is generally agreed that the tangential AC breakdown strength of solid-solid surfaces is primarily determined by the elastic modulus (elasticity), radial/tangential pressure, surface smoothness/roughness, and dielectric strength of the ambient environment. For this purpose, we made use of dextrin and Arabic gum. Physical parameters (Lap shear strength, pull off strength, hardness, roughness, electrical and thermal insulations) of the combination formed with varying amounts of each ingredient were investigated. The adhesive characteristics of D were enhanced by the incorporation of AG, with improved pull off adhesion and lap shear strength at increasing AG levels at 80%. D /AG 20/80 compositions had pull off adhesion values 189 times greater than pure D, and lap shear strength values 820 times higher. It is evident because of the dispersion of AG molecules in decreasing the surface roughness of D/AG films and increasing their hardness on the shore scale. There is a positive correlation between the amount of AG added and the blending matrix of D, therefore boosting A with AG increases A. The dielectric strength, and thermal insulation increases with the increase in the weight ratio of Arabic gum. The blend prepared as an adhesive for wood is a good electrical and thermal insulator at 8% AG/20% D.","PeriodicalId":14665,"journal":{"name":"Iraqi Journal of Industrial Research","volume":"11 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138974677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hydrothermal technique was used to synthesize the transport layers. According to the results, using TiO2/G as an electron transport layer enhances the transfer of negative charges from perovskites, which increases the efficiency of the solar cell. This is thanks to improved electrical conductivity and less loss of negative charges in the transport layer. The positive gap transition from the perovskite layer to the gap transport layer was enhanced using ZrO2/G. The chemical and physical properties of ZrO2/G help to build a strong interface with perovskite, which promotes gap crossing and reduces the loss of positive charges. Regarding the photonic layer, the efficiency of the solar cell increased significantly when CsPbBr3 quantum dots were used as the active element due to their strong abilities to absorb light from the visible light spectrum according to absorption spectrometry measurements. The efficiency of converting light into electrical charges increases because they can absorb more sunlight, including low-level solar energy. Quantum dots have efficient charge transfer paths, which reduces charge loss and improves conversion efficiency. CsPbBr3 quantum dots are chemically and crystallineally stable. These factors work together to increase the efficiency of the perovskite solar cell when using CsPbBr3 quantum dots from 10.004% to 10.425%.","PeriodicalId":14665,"journal":{"name":"Iraqi Journal of Industrial Research","volume":"28 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139003243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
