In this paper, we have improved solutions for two of the Multi-Criteria Machine Scheduling Problems (MCMSP). These problems are to maximize early jobs time and range of lateness jobs times (1//(E_max,R_L ), and the second problem is maximum tardy jobs time and range of lateness jobs times (1//(T_max,R_L ) in a single machine with Multi-Objective Machine Scheduling Problems (MOMSP) 1//(E_max+R_L ) and 1//(T_max+R_L ) which are derived from the main problems respectively. The Local Search Methods (LSMs), Bees Algorithm (BA), and a Simulated Annealing (SA) are applied to solve all suggested problems. Finally, the experimental results of the LSMs are compared with the results of the Branch and Bound (BAB) method for a reasonable time. These results are ensuring the efficiency of LSMs.

The study investigates the effect of radioactive sources on Salmonella typhi, a gram-negative, rod-shaped bacterium that infects various cell types. Salmonella primarily spreads through contaminated food, commonly tainted by human or animal waste. In this descriptive research, 50 S. typhi samples from diverse patients at Baghdad Hospital were utilized. The method involved identifying the bacteria using Viteck2, culturing them on Nutrient broth and Nutrient agar, and exposing them to various radioactive sources: Na23 and CO60 (1 µCi and CO60 10 µCi). Petri dishes containing Nutrient agar were used for sample plating, followed by incubation for 24 hours at 37°C. The results showed that exposure to beta and gamma rays emitted by Na23 at an activity level of 10 µCi resulted in increased radiation levels with time. Without Almmonium, the radiation doses for 1, 2, and 3 hours were 9.64 mSv, 19.29 mSv, and 28.93 mSv, respectively, leading to varying viable cell counts. With Almmonium, the doses for the same periods were significantly lower, with fewer viable cells. Similarly, exposure to CO60 (1 µCi) resulted in varied radiation levels and viable cell counts, indicating a similar trend with and without Almmonium. CO60 (10 µCi) also demonstrated an increase in radiation doses over time, displaying an impact on viable cell counts. The study concludes that radiation emitted from Sodium and Cobalt radioactive sources exhibited effectiveness in eliminating S. typhi in direct proportion to increased exposure time and dose. This research highlights the potential for radioactive sources to impact the viability of Salmonella typhi cells.

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by autoantibody's presence in the circulation and involvement of many systems. The current study aims to study the role of some immunological and non-immunological parameters in SLE development and to illustrate the correlations between these parameters. The current study included 50 blood samples collected from SLE patients and apparently healthy control. The methods of work included Complete Blood Count (CBC) analysis to assess blood components, you mean to analyse Hb, WBC, ESR, ELISA technique to measure serum levels of TLR-7, IL-17, and TNF-γ, antinuclear antibody test (ANA) and double-strand DNA antibody (anti ds DNA). The study results showed a significant increase in serum levels of each WBC (p< 0.005), ESR (p< 0.001), IL17(p< 0.004), TLR7(p< 0.005), IFN-γ (p< 0.001), ANA (p< 0.001), and anti dsDNA (p< 0.001) in SLE patients compared to apparently healthy control but the Hb is decreasing level was low in the SLE patients compared with control. In conclusion, the low hemoglobin, WBC, and ESR are non-specific parameters associated with SLE pathogenesis. ANA, Anti-ds-DNA as excellent biomarkers for the diagnosis of SLE and serum level of TLR-7, TNF-γ, and IL-17 were evaluated in SLE patients compared to healthy people and they may be suggested as a prognostic tool in SLE patients.

The test was conducted on a sample consisting of mixing three samples of Iraqi Aromatic rice (Amber) bran obtained from the private mills in Najaf Governorate. The MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) method was used to study the cytotoxic effect of alcoholic and aqueous extract of Iraqi Aromatic rice bran on B16 cell line, it is a murine tumor cell line used as a model to study human melanoma. The results showed that all concentrations of alcoholic extract (5, 10, 20, 40, and 80) % caused a significant inhibition on the B16 cell line. The inhibition rate reached to (13.00, 27.00, 47.33, 71.67 and 86.67) % respectively, after 48 hours while the cell viability was (87.00, 73.00, 52.67, 28.33and 13.33) % with a statistically significant difference at P≤. 0.05 compared to the control. The results showed that the aqueous extract had less inhibition effectiveness (for the same concentrations) after 48 hours, (10.00, 19.33, 27.00, 46.67 and 66.33) % and the cell viability rate was (90.00, 80.67, 73.00, 53.33 and 33.67) % respectively. The study shows that both alcoholic and aqueous extract prepared from Iraqi Aromatic rice bran had a toxic and anti-proliferative effect on B16 cell line, and this effect increases with increasing concentration. Treatment of these cells with the two extracts caused shrinkage, a decrease in numbers, and a clear morphological change in this type of cells.

Due to the population's health risk, radon has emerged as a major worldwide health problem. 50% of the total eugenic radiation dose is caused by radon and its progenies; therefore, pollution of river water with minerals and radon that cause serious harm to human health. Through the practical results obtained, the theoretical results were linear and a high correlation coefficient. Radon concentrations were measured with CR-39 nuclear track detectors (NTDs). Radon gas concentration and annual effective dose were below the recommended limits. This indicates that the water of the Euphrates River is safe for aquatic life.

A thin film of polyvinylpyrrolidone (PVP) polymer doped with different weight ratios of magnesium oxide nanoparticles produced by using the low-temperature hydrothermal method was prepared, and the morphology of the doped thin film was verified using a scanning electron microscope and an atomic force microscope. The X-ray diffraction pattern showed that magnesium oxide has a multi cubic crystal structure with a diffraction peak of high density associated with the level (200) (at the diffraction angle of 42.69◦) and a crystal drop size of 25 nm. Measurements of the Fourier A transformation of the infrared spectrum of a polyvinylpyrrolidone polymer doped with metal oxides was carried out. It showed a clear difference from the pure polymer, where a (Mg-O-Mg) bond appeared at a wavelength of 450 cm^-1 to confirm the effect of MgO addition on the chemical bonding of polyvinylpyrrolidone. Optical properties, including absorbance, maximum wavelength, and energy gap, have been studied. Determined by ultraviolet examination. The band gap decreased when MgO was doped with PVP films, and the Hall coefficient effect was used to calculate the electrical properties, including the conductivity, kinetics of charge carriers, and their type. The highest conductivity was (0.1*10^-2 Sm), and the tainted membrane was of the n type), where it can be used in optical applications.

The rapid tech growth and widespread internet usage caused a surge in sharing multimedia (text, images, videos, audio) across public networks. Protecting this data is vital, demanding encryption to prevent unauthorized access. Image encryption distorts images for security. This paper highlights encryption's vital role in safeguarding multimedia, especially amid rising internet use and media exchange. It introduces a novel solution: a chaotic three-dimensional system for color image encryption. The study scrutinizes system traits using math software. It employs a new chaotic system to generate a crucial key sequence for pixel scrambling. Utilizing stream cipher encryption enhances security. Extensive security analysis tests its resilience against attacks like histogram and correlation techniques. Results are promising: a fairly uniform histogram, minimal correlation among pixels nearing zero, and entropy close to the ideal. Metrics like NPCR and UACI almost match ideal values, ensuring high security. Experiments confirm its effectiveness in encrypting diverse color images. The approach guarantees a uniform histogram, minimal pixel correlation nearing zero, entropy near the ideal value (8), and NPCR/UACI values close to ideals (99.61191% and 33.41068% respectively).

Medical image processing has become one of the crucial elements of the diagnostic process because of the increased usage of medical imaging recently, and clinicians' dependence on such computer-processed medical images in diagnosing patients. As the traditional Canny edge detection algorithm is sensitive to noise, it is easy to lose weak edge information when filtering out the noise, and its fixed parameters show poor adaptability. The suggested algorithm introduced the concept of image block intensity operator to replace image gradient. In addition, the computing speed of the suggested algorithm is relatively fast because it works block by block rather than pixel by pixel. Two adaptive threshold selection methods are presented, one based on the median accumulative histogram of image gradient magnitude and the other on the standard deviation for both types of image pixels (one with less edge information and the other with rich edge information). The proposed algorithm can be dividing into four stages: Input the medical digital image, convert the color medical image to gray-scale, applied improved canny edge detection, then calculate the MSE & PSNR Measures, in addition conduct a visual questionnaire by oncologists to find out which method that made the enhancement of the medical image clearer.

The simulate microphysical processes in the atmosphere, a cloud chamber, which behaves as the atmosphere, has been designed and fabricated in order to be used to execute several atmospheric experiments. These experiments allow a better understanding of clear visual cloud formation. The executed temperature and saturated pressure experiments clarify the basic mechanisms of the ice crystals nucleation, which in contrast, represent the core of the cloud microphysics. The cloud chamber can represent an isolated environment that deals with a certain volume of pure air and contains certain nucleation particles or ice nuclei. The temperature range in such a chamber is similar to that found at the mid-latitudes between the surface of the earth and the top of the troposphere. Thus, it is possible to simulate clouds of the type of Cirrostratus at the bottom of the chamber. It has been designed with dimensions of 22×22×59 cm3 and made of 3mm in thickness copper with a purity of 99.9%, and thermal conductivity of 401 W/m.°K.

These experiments allow a better understanding of clear visual cloud formation. The executed temperature and saturated pressure experiments clarify the basic mechanisms of the ice crystals nucleation, which in contrast, represent the core of the cloud microphysics. The cloud chamber can represent an isolated environment that deals with a certain volume of pure air and contains certain nucleation particles or ice nuclei. The temperature range in such a chamber is similar to that found at the mid-latitudes between the surface of the earth and the top of the troposphere.
