The effects of the new (2020) and old (2012) engines on the most important parameters, kinematic viscosity, flash point, and fire point were investigated. Measurements were performed on four-engine oil samples. Profi-car Endurance SAE 10W-30 semi-synthetic was used for all the engines. The maximum trip length for the oil samples was 8,000 Km. Kinematic viscosity was measured by using a KV1000 Bath (according to the ASTM D445). In addition, the flash point and fire point of the samples were determined by using the Open Cleveland method. This work investigates the difference between old and new engines in actual use on the roads in the rate of decrease in engine oil properties. The cumulative results obtained help drivers protect their car engines by changing engine oil when the engine’s mileage is above 100,000 Km. The comparison of the average results shows that the rate of deterioration of used oil in old engines is higher than in the new engines. It has been shown that the rate of difference in oil viscosity deterioration between old and new engines at cold temperatures, 40°C, and 100°C were 9.3%, 10%, and 4.78% respectively. Also, the different rate for the oil flash points and fire points was 5.56% and 6.75%.","PeriodicalId":33835,"journal":{"name":"Passer Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45824032","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}

{"title":"Effect of Blending Aromatic and Oxygenates Additives with Fuels to Enhance Fuel Properties","authors":"Ahlam Kareem, Z. Ahmed, S. Mustafa","doi":"10.24271/psr.2022.360689.1159","DOIUrl":"https://doi.org/10.24271/psr.2022.360689.1159","url":null,"abstract":"This work aims to show the influence of several oxygenates and aromatic additives in different types of unleaded fuels in the Kurdistan region of Iraq on upgrading the physicochemical properties of blends. Consuming super-grade gasoline as a fuel for automotive cars can produce large amounts of environmental emissions, a severe global problem, especially in the Kurdistan region in recent years. The physicochemical properties of mixtures, such as the research octane number (RON), Motor Octane number (MON), density, and distillation curves, will be tested by using ERASPEC spectroscopy as a fuel properties analyzer. As a result, the blending process has improved the gasoline grade to super grade by enhancing the physicochemical properties of blends. The additives used in this work as oxygenators are; Ethanol and Methyl Tertiary Butyl Ether (MTBE) added to two base fuels, light Naphtha, and unleaded Gasoline, in various ratios of (5%, 10%, 15% and 20%). An aromatic component (Aniline) is also mixed with light Naphtha and base gasoline in low concentrations (1%, 3%, and 5%). The results of blending Ethanol, MTBE, and Aniline with fuels demonstrate that the Research Octane Number (RON) and Motor Octane Number (MON) of fuels increase with the addition of different ratios of all-octane boosters. The best-recorded result of both types of octane numbers (13 points increased from the bases) is recorded by blending 3% of Aniline with the fuels. However, Ethanol can provide a more significant increase in RON and MON than Methyl Tertiary Butyl Ether (MTBE) for the same blending ratio. The Density of the mixtures also increases because both additives have a higher density than the fuel due to the presence of different hydrocarbon compounds. The mixture's distillation curves are distorted, especially when the low to the middle percent of blenders are added to fuels. However, higher percentages of additives show lower distillation temperatures. © 2022 Production by the University of Garmian.

The main aim of this study is to highlight the effect of mobile pandemic applications in Iraqi society and the trustworthiness of developers and distributors of apps. To this end, we explored differences in the attitudes of smartphone users toward pandemic apps and shared the data to conduct research. The method adopted to achieve the Survey in this study is an Email and telephone-based Survey of (318) participants adults over 18 years old in Iraq. We used a total of (315) for Statistical Analysis. This 9-item Survey examined the current use of epidemic applications, motivations for using them, trust in app distributors, data handling, willingness to share coded data with researchers using a pandemic app, attitudes toward app use among people, demographics, and personal characteristics. The results of this study showed that most participants stated they were using smartphones (307/315, 97.5), but only (77/307, 24.4) were using pandemic apps on their smartphones. Intriguingly, in this Survey, when participants asked for the preferable organizations for storing data and application division, trust in federal or state government, regional health office, public-appointed such as statutory health insurance, or government-funded organizations (research institutes) was much higher than in private organizations (private research institutions, clinics, health insurances, information technology companies). © University of Garmian.

In the program model, mammography is conducted for normal and symptomatic women. This study aims to assess the program’s model effectiveness in terms of mammography cancer detection rates and other screening determinates in the Iraqi Early Detection Program. Method: This is a retrospective study based on data from the Breast Disease Treatment Centre (BDTC) in Sulaimani, Iraq. From September 2016 to August 2021, 35,045 women visited the centre for BC screening and diagnosis of breast disorders. In BDTC, 16,186 mammograms and 1,289 biopsies were conducted, and 404 women were diagnosed with BC. This study measured the percentage of women who visited BDTC for screening, the women’s ages at diagnosis, the cancer detection rate (BC per 1,000 women visiting), the mammography detection rate (BC per 1,000 mammograms) and the percentage of positive core biopsies. Results: The cancer detection rate (CDR) in 1,000 women was 11.53, the overall mammography detection rate was 24.96, and the highest rate was observed in 2018 (42.2). The overall percentage of positive core biopsies was 31.34%. The highest percentage biopsy rate was in 2017 (43.84%). From 2016 to 2021, the percentage of visits for screening increased gradually, rising from 9.5% to 28.6%. Conclusion: The early detection program in Iraq is considered effective in terms of high mammography cancer detection rates and the percentage of positive biopsies. Compared to the previous data, more women participated in the program for screening than for diagnosis. https://creativecommons.org/licenses/by-nc/4.0/","PeriodicalId":33835,"journal":{"name":"Passer Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68882184","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}

COVID-19 infected individuals, according to a clinical study, are most usually contaminated with a severe condition after coming into a primary infection. The chest radiograph (also known as the chest X-ray or CXR) or a chest CT scan is a more reliable imaging method for diagnosing COVID-19 infected individuals. This article proposed a novel technique for classifying CXR scan images as healthy or affected COVID-19 by fusing the features extracted using Histogram of Oriented Gradient (HOG) and Local Phase Quantization (LPQ). This research is an experimental study that employed 7232 CXR images from a COVID-19 Radiography dataset as training and testing data. As a result, by using both individual and fused feature extraction methodologies, a developed model was created and fed into the machine learning techniques.

According to previous studies, this sequence is designated as Red Beds Series (RBS), consisting of more than 2000 m of fine and coarse red and grey clastics. The present study found recently recognized lithologies (RRLs) about 100 thick inside the series and encompassed green marlstone with subsidiary detrital limestone which has significant tectonic and paleogeographic results. The petrography, biostratigraphy, and boundary conditions studies are applied to uncover their origin. The new lithologies are deposited in the subsiding basin in the Imbricate Zone during the Middle Eocene. During this age, the Tertiary Foreland Basin was separated by a paleohigh into two basins, (northern and southern basins). In the northern basin, the RRLs have deposited as deep facies of the Naopurdan Formation while in the southern basin the Pila Spi Formation was deposited as lagoonal facies. The former formation was deposited as reefal facies in the shelf area of the northern basin to the northeast Chawrta and Mawat Towns. The RRLs, units one and two of the series (in the Thrust Zone) are correlated respectively with Pila Spi, Sinjar and Gercus formations in the High Folded Zone. These correlations are shown on the stratigraphic columns and paleogeographic models with the aid of nannofossil and benthonic foraminiferal studies. This study is the most important step for solving the tectonic and paleogeographic setting of northeastern Iraq and for a better understanding of the Zagros Collisional belt.","PeriodicalId":33835,"journal":{"name":"Passer Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48689473","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}
