Films of poly (methyl methacrylate) PMMA and PMMA doped with zinc oxide nanoparticles (ZnONPs) with different amounts were created using the solution casting technique. Different amounts of zinc oxide ranging from (0.001-0.005) g in step 0.001g were investigated and added to a polymer of constant amount (0.5) g of PMMA in 15ml Tetrahydrofuran (THF). It is known that increasing the amount of ZnONPs in this technique contributes to the appearance of ZnONP peaks within the polymer. The differences in the XRD spectrum show that the nanomaterial changed the microstructure of the polymer. This was discovered using a nanoscale scanning electron microscope (SEM). SEM revealed that the PMMA polymer surface exhibit an amorphous nature with a smooth surface. Fourier Transform Infrared (FTIR) spectroscopy demonstrates that there was no chemical reaction between the PMMA polymer and ZnONPs. Spectrophotometric measurements of absorbance and transmittance in the wavelength range 200- 900 nm were used to evaluate the optical characteristics of all films. Increased amounts of ZnONPs improve the absorbance, absorption coefficient, and extinction coefficient of PMMA polymer. With increasing ZNO content, the variance in computed optical energy gap values has been interpreted, the optical energy gap dropped from 4.65 eV to 4.10 eV. The solar radiation intensity in Baghdad for the pure PMMA films and PMMA/ZnO nanocomposites was measured at a rate of 1 hour for seven days in beginning in early September 2021, from 6 A.M to 6 P.M (13 h). As can be observed, almost all films have the same ratio of intensity of transmitted radiation to intensity of sunlight for all hours and days.

In this paper, our purpose is to study the classical continuous boundary optimal triple control vector problem (CCBOTCVP) dominating by nonlinear triple parabolic boundary value problem (NLTPBVP). Under suitable assumptions and with given classical continuous boundary triple control vector (CCBTCV), the existence theorem for a unique state triple vector solution (STVS) of the weak form W.F for the NLTPBVP is stated and demonstrated via the Method of Galerkin (MGa), and the first compactness theorem. Furthermore, the continuity operator between the STVS of the WFO for the NLTPBVP and the corresponding CCBTCV is stated and demonstrated. The continuity of the Lipschitz (LIP.) operator between the STVS of the WFo for the QNLPBVP and the corresponding CCBTCV is proved. The existence of a CCBOTCV is stated and demonstrated under suitable conditions.

Hormones are thought to primarily influence cancer risk by regulating the pace of cell division, cell differentiation, and the amount of cancer-vulnerable cells. Higher insulin levels and cortisol have been linked to some cancers, including breast cancer. Here, we evaluated the relationship between insulin and cortisol signaling and cancer, as well as the effect of these two hormones on organs, subcellular elements, and the process of carcinogenesis. We also consider the time points to prevent and cure breast cancer in insulin signaling. The ultimate objective is to enhance general health. Insulin and cortisol levels were tested and the results showed much higher insulin levels in breast cancer patients compared with control (p<0.001), whereas cortisol levels tested were lower in breast cancer patients compared with control with no statistically significant changes (p>0.05).

Colorectal cancer (CRC), the second most fatal cancer and the 3rd most common cancer is expected to cause 0.9 million deaths globally in 2025. Carcinoembryonic antigen (CEA) is currently used in the follow-up of patients with colorectal cancer, and in this study, we are trying to find a better marker than CEA in following up on patients' health and knowing the effectiveness of the treatment used and as a diagnostic marker for colorectal cancer. To determine the significance of Cancer antigen 72-4 (CA72-4) as a prognosis predictor in patients with colorectal cancer, compare its prognostic validity to the CEA biomarker. this case-control study includes (150) participants, 100 patients (59 males and 41 females), and 50 healthy controls (26 males, 24 females). Blood samples were collected from all participants to measure the serum concentrations of CA72-4 and CEA using an enzyme-linked immunosorbent assay (ELISA). Between November 2020 and February 2021 in Baghdad, Iraq, this investigation was conducted at the oncology teaching hospital's gastrointestinal consulting clinic. There was a strong positive relation between CA242 and CEA (R = 0.953, p <0.001) and participants with colorectal cancer had considerably greater levels of CA72-4 than healthy controls (p <0.001). AUC was 0.944, sensitivity was 86%, specificity was 94%, and the cutoff value was 50 U/ml for the CA72-4. while AUC was 0.919, sensitivity was 91%, specificity was 80%, and the cutoff value was 5 ng/ml for the CEA.CA72-4 can serve as a potential prognostic and diagnostic biomarker for colorectal cancer.

People in most countries suffer from tooth decay due to various reasons, and the germs responsible for tooth decay show an increase in resistance towards standard antibiotics used in treatment because of the inappropriate and indiscriminate use of these antibiotics. This study aimed to search for natural products that have fewer side effects and are more effective for treatment. Natural verjuice was used to study its effectiveness against some bacterial species including Escherichia coli, Streptococcus mutans, Staphylococcus aureus, and Pseudomonas aeruginosa that cause caries, which were obtained from the Microbiology Research Laboratory in a previous study. The results showed the superiority of the effectiveness of verjuice over the effectiveness of most of the selected antibiotics against the studied bacteria, which confirms its effectiveness as a natural product without the need to extract the active substances with organic solvents.

Solar energy is the most abundant renewable energy source. This energy can be converted directly into electricity using solar panels. The fixed tilt solar panels are the most practical and the most widely installed throughout the world. Optimum tilt angle calculation has the advantage that it does not use expensive solar trackers. This research calculates the seasonal optimum tilt angle of solar panels for 17 cities in Iraq and 83 cities in 83 countries distributed around the world. Solar Panel Angle Calculator program was used in calculating the optimum tilt angles from vertical. The optimum tilt angle varies between 6° and 112° throughout the year. This angle for winter, spring/ autumn and summer seasons are found to be between 6° to 66°, 30° to 89° and 54° to 112°, respectively. All angles calculated from the calculator program are validated by comparing it with those obtained from equations. An excellent agreement was established. Cities which have approximately the same absolute values of the latitudes are have the same optimum tilt angles. Based on the results, adjusting angles four times a year is recommended. This work can serve as a guidance for installing solar panels.

Apolipoprotein B100 (ApoB100) provides a good assessment of atherogenic lipoproteins (very low, intermediate, and low-density lipoproteins (VLDL, IDL, and LDL)). There is evidence that polymorphism of ApoB100 was observed in many conditions and it links with obesity, diabetes mellitus hypertension, and chronic inflammation, which could be related to the broad field of the atherothrombotic process, and could be one of the leading causes of coronary artery disease (CAD). It can be computed using a formula that makes use of a measurement of non-high-density lipoprotein levels. This study aimed to derive an estimated equation of ApoB100 from the measured ApoB100 levels specific to the healthy subjects of Kurd race/ethnicity in the Kurdistan region of Iraq taking into consideration the gender-based effect and the status of fasting and postprandial effects. A total number of 45 healthy subjects (23 males and 22 females) were enrolled in the study. The following measurements were achieved: anthropometric indices, blood pressure, lipid profile, including ApoB100, and blood sugar. The biochemical measurements were carried out at fasting and postprandial states. Specific equations were derived for calculating the levels of ApoB100. Significant differences in the anthropometric indices, blood pressure, and lipid profile were observed between males and females. The calculated ApoB100 levels were significantly less than the measured ApoB100 levels in both genders and fasting and postprandial states. The estimated equations for ApoB100 for females have differed from that for males at fasting and postprandial states. The levels of ApoB100 can be determined instead of measuring it in the laboratory by using a specific equation for healthy Kurd people. These equations are gender and race/ethnicity based. The established equation of estimated ApoB100 levels in males differed from that in females which is attributed to the cardio-metabolic factors and higher levels of systolic and mean arterial blood pressures among males. Apo B level is a quantitative index of plasma atherogenic lipids in hypertensive patients who presented with dyslipidemia.

Text summarization is an important research topic in the field of information technology because of the large volume of texts, and the large amount of data found on the Internet and social media. The task of summarizing the text has gained great importance that requires finding highly efficient ways in the process of extracting knowledge in various fields, Thus, there was a need for methods of summarizing texts for one document or multiple documents. The summarization methods aim to obtain the main content of the set of documents at the same time to reduce redundant information. In this paper, an efficient method to summarize texts is proposed that depends on the word association algorithm to separate and merge sentences after summarizing them. As well as the use of data mining technology in the process of redistributing information according to the (K-Mean) algorithm and the use of (Term Frequency Inverse Document Frequency TF-IDF) technology for measuring the properties of summarized texts. The experimental results found that the summarization ratios are good by deleting unimportant words. Also, the method of extracting characteristics for texts was useful in grouping similar texts into clusters, which makes this method possible to be combined with other methods in artificial intelligence such as fuzzy logic or evolutionary algorithms in increasing summarization rates and accelerating cluster operations.

Also, the method of extracting characteristics for texts was useful in grouping similar texts into clusters, which makes this method possible to be combined with other methods in artificial intelligence such as fuzzy logic or evolutionary algorithms in increasing summarization rates and accelerating cluster operations.","PeriodicalId":7867,"journal":{"name":"Al-Mustansiriyah Journal of Science","volume":"127 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90293572","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 aim of this paper is to define new concepts, A homogenous system of difference equations is called -semi homogenous of order if there exists a non-zero matrix
本文的主要目的是定义一些新概念，如果存在一个非零矩阵，则称齐次差分方程组为阶-半齐次
