Impact of Textiled-Poly Bags as Economic and Environmentally Friendly Recycled Fibers on Mechanical Features of Soil

Heba A. Ahmed — 2023-07-10

Newly, the utilization of polypropene for packaging consumer products was populated significantly, which might make ecological problems. So, it is substantial to detect environmentally friendly techniques to recycle these waste substances without causing any environmental risks. One such technique could be the utilize poly wastes as stabilizer agents for soils. In the current investigation, textiled-poly bags (TPB) have been recycled and fabricated to be economy and environmentally-friendly fibers. The impact of utilizing different proportions and lengths of these fibers on the mechanical features of clayey soil has been evaluated. The investigation depended on four different fiber-proportions (1, 2, 3, &4)% of soil weight in two different lengths (1&2) cm. Geotechnical experimental test consequences demonstrated that the recycled fiber pieces minimize the optimum dry density (ODD) and the corresponding optimum water content (OWC) of the treated soil samples. Additionally, there was a notable increment in the uniaxial compression test results of the treated soil samples. Moreover, the consequences of California Bearing Ratio tests showed that the utilization of recycled TPB fibers in clayey soil samples enhances the resistance and deformation performance of the soils specially when utilizing 4% of recycled TPB fibers for both lengths (1 & 2) cm.

Clinical Prediction of Blood Parameters Associated with Breast, Colon, Thyroid, Ovarian, and Prostate Cancer

Ali J. Muhialdin — 2023-07-20

Cancer is a cellular change caused by uncontrolled cell growth and division. This disease develops from the growth of abnormal cells that have the potential to invade or spread to other parts of the body. The aim of this study was to investigate the relationship between blood parameters (e.g., Mean corpuscular volume (MCV), Mean corpuscular hemoglobin (MCH), Mean Corpuscular Hemoglobin Concentration (MCHC), Haemoglobin (HGB), White Blood Cell (WBC), and Red Blood Cell (RBC)) and different types of cancer. Breast cancer, thyroid gland cancer, ovarian cancer, testicular cancer, brain tumors as well as other types of cancer are based on the cell of the tissue found on or in the body. Any of these types of cancer are associated with a variety of health issues that put the patient's life in danger. Performing the complete blood count (CBC) test prior to or after a cancer diagnosis is necessary as abnormalities in the body can cause blood component rates to either increase or decrease, depending on the type of cancer, the patient's physiological mechanism, and the structural component. Since the CBC test belongs to hematology, drawing a blood sample and putting it into the anticoagulant tube for testing were preferred. In this study, the blood components of almost all patients were normal except for a few of them which may be due to other medical and biological factors. There is a significant relationship between blood parameters and cancer types.

The Opinion and Awareness of Citizens on the Commitment of Bakers, Butchers, and Food Sellers to Health Instructions and their Application during COVID-19 Outbreak

Yaseen Galali — 2023-07-30

Many countries follow the recommendation of the World Health Organization (WHO) by practicing physical gathering avoidance as one health measure to decrease COVID-19 the spread. The current study identifies the opinions and awareness of citizens about the commitments of workers (bakers, butchers, and food sellers) to health instructions and prevention. This descriptive cross-sectional study was done in different premises in Kurdistan Region-Iraq from 20.9.2021 to 20.4.2022 using online platforms and printed forms. The study included socio-demographic characteristics, citizens' opinions, and commitment related-questions. A thousand copies were collected and analyzed. The results showed that the majority of citizens have positive opinions and awareness and agreed that workers (bakers, butchers, and food sellers) are committed to COVID-19 regulations. There was a significant correlation between the variables of opinions and awareness of the commitments of workers to the prevention of COVID-19. All professional workers have a good obligation to prevention from COVID-19 so that the population in the Erbil city has accepted those workers to deal with food and meat and with complete prevention from Covid-19. These perfect commitments of workers to prevention may help to break down the chain of COVID-19 infection which consequently reduces mortality and morbidity rate.

Applying the Bayesian Technique in Designing a Single Sampling Plan

Dler H. Kadir — 2023-08-05

The Bayesian sampling plans for production inspection are considered a technique of sampling inspection techniques for determining the characteristics of the sampling plan based on the assumption that the rate of defectives is a random variable that varies from one production batch to the next, resulting in a probability distribution f(p) that could be determined based on experience and the available quality information available. As part of this study, the parameters of a single Bayesian sampling plan (n,c) were derived by using the Beta-Binomial distribution and compared with those of other single sampling plans. Researchers have identified (ALA company for soft drinks), which handles product quality control. 120 production batches were selected, and the size of the batch and the number of defective items were used to determine the proportion of defective items, given that the variable varies randomly from one production batch to the next. Bayesian and decision-making models can be implemented to create a single sampling inspection process that is close to the actual quality level. The researchers discovered that when the decision-making model was used, the sample size was minimal compared to other inspection plans, leading to a low inspection cost.

Physical and Mechanical Properties of an Artificial Aggregate Made up of Ground Granulated Blast-Furnace Slag

Mais A. Ibrahim — 2023-08-25

Manufacturing artificial aggregate by utilizing waste materials has gained great importance as the aggregate occupies a high volume in concrete (60–70%). In this paper, ground granulated blast furnace slag (GGBFS) is utilized in aggregate manufacturing. Cold bonding and sintering methods were used as production processes. The pellets were put through a series of tests like dry density, specific gravity, water absorption, and crushing strength. The results indicated that the density of pellets increased by increasing the GGBFS dosage while the water absorption capacity was reduced. Furthermore, the highest crushed strength was recorded at 50% addition of GGBFS.

Electromagnetic Field Pollution Level Measurement for Mobile Phone Networks at Cihan University-Erbil

Adil H. Mohammed — 2023-08-25

The health effects by impact of radio-frequency (RF) electromagnetic fields (EMF) have become of increasing concern. We conducted a Specific Absorption Rate (SAR) study and measurements of wireless and mobile phone networks to evaluate the hazard of RF radiation limit. Our measurements have been carried out at different locations on the campus of Cihan University – Erbil. The RF strength level measurement of a base station on site was done by using spectrum analyzer with a dipole antenna and Electro Magnetic Field detector (EMF) application in the handsets for mobile networks, then comparing our measurements with the international slandered SAR’s levels.
