Image retrieval is an active research area in image processing, pattern recognition, and
computer vision. In this proposed method, there are two techniques to extract the feature
vector, the first one is applying the transformed algorithm on the whole image and the second
is to divide the image into four blocks and then applying the transform algorithm on each part
of the image. In each technique there are three transform algorithm that have been applied
(DCT, Walsh Transform, and Kekre’s Wavelet Transform) then finding the similarity and
indexing the images, useing the correlation between feature vector of the query image and
images in database. The retrieved method depends on higher indexing number. <

The effect of temperature range from 298 K to 348 K and volume filler content ф on electrical properties of polyethylene PE filled with nickel Ni powders has been investigated. The volume electrical resistivity V  of such composites decreases suddenly by several orders of magnitude at a critical volume concentration (i.e. фc=14.27 Vol.%) ,whereas the dielectric constant   and the A.C electrical conductivity AC  of such composites increase suddenly at a critical volume concentration (i.e. фc=14.27 Vol.%).For volume filler content lower than percolation threshold ф<фc the resistivity decreases with increasing temperature, whereas the dielectric constant and the A.C electrical conductivity of

In this work, we calculate and analyze the photon emission from quark and anti-quark interaction during annihilation process using simple model depending on phenomenology of quantum chromodynamic theory (QCD). The parameters, which include the running strength coupling, temperature of the system and the critical temperature, carry information regarding photon emission and have a significant impact on the photons yield. The emission of photon from strange interaction with anti-strange is large sensitive to decreases or increases there running strength coupling. The photons emission increases with decreases running strength coupling and vice versa. We introduce the influence of critical temperature on the  photon emission  rate in order

It has been shown that the presented model has the best accuracy and efficiency compared to the differen

         The present pandemic of Coronavirus Disease 2019 (COVID-19) causes a multitude of lasting impacts on the human body. It has immediate and extensive effects on the human body, particularly the thyroid gland. A rise in adenylyl cyclase 2 (ACE2) and transmembrane serine protease 2 (TMPRESS2) makes it easier for viruses to get into human cells. COVID-19 triggers a hyperactive immune response that produces interleukin-6 (IL-6) and other pro-inflammatory cytokines. This hyperactive immune response leads to severe thyroid malfunction. The current study aimed to research the relationship between the recovering Iraqi subjects of COVID-19 and thyroid hormones and lipid profiles. This study aims to evaluate triiodothyronine (T3), thyr

     Osteoarthritis (OA) is a degenerative disease that causes pain in humans' joints during movement, especially in the elderly and many women. Since cartilage plays a major destructive role during OA incidence, its chemical components can serve as a sensitive biomarker for diagnosing the onset and severity of OA disease. Cartilage acidic protein 1 (CRTAC1) is a critical component of the cartilage's extracellular matrix. We have aimed to test the sensitivity of CRTAC1 to the prognosis of OA disease in pre-and post-menopausal women with OA disease. The results showed that the levels of CRTAC1 in the serum of pre-and postmenopausal women with OA disease were significantly higher than those in control groups of the same age. C-reactive

     Acromegaly is a condition that results from excessive growth hormone production by the anterior pituitary gland. Prolidase (PLD) is the only known human enzyme that can hydrolyze dipeptides with an amino acid at their C terminus. Reports indicate that PLD activity serves as a marker for oxidative stress in numerous disorders such as diabetes, diabetic neuropathy, chronic liver diseases, and osteoporosis. The current study aims to estimate the values of PLD, its correlation with the rest of the parameters, and ROC in acromegaly patients. A group of 61 patients with confirmed acromegaly were collected from the National Diabetic Center, Mustansyrriah University, and 60 control groups were analyzed in the same place for the paramete

Nowadays, there is an increase in interest in creating and researching silver nanoparticles (AgNPs) because of their numerous applications in many fields, especially medical fields such as burn, wound healing, dental and bone implants, antibacterial, viral, fungal, and arthropodal activities.

In response to the water crisis, further research is necessary to comprehend the impact of human activities on nutrient concentrations in aquatic ecosystems, building on the extensive studies already conducted to understand these impacts on the water quality of various aquatic ecosystems. We hypothesized that human activities in the Tigris River's catchments could alter the nutrient concentrations in the water along the river. The results showed that phosphate concentration differed significantly among the studied sites due to distributed human activities, while nitrate concentration did not. Water temperature did not affect phosphate and nitrate concentrations. We concluded that human activities on the surrounding landscapes could be mo

     Diabetes mellitus (DM) is a chronic metabolic disorder characterized by persistent hyperglycemia. It may be due to impaired insulin secretion, resistance to insulin's peripheral actions, or both. The aim of this study was to estimate the percentage impact of obesity on the incidence of DM, as well as compare the levels of Apelin-36, glutathione-S-transferase, and insulin resistance (IR) in subjects with and without DM for both sexes. This study included 120 subjects, divided into 60 as a control group and 60 as a patient group of both sexes; all were adults between the ages of 30 and 65. The participants with fasting blood sugar, lipid profile, glycated hemoglobin (HbA1c), apelin-36, body mass index, insulin hor

Although considered a good alternative to organophosphate pesticides, there are reports indicating adverse effects of neonicotinoid insecticides on reproduction. The present work was designed to determine the chronic effects of orally administered for treated with 20 mg/kg/b.w. of imidacloprid pesticides and treated with 20 mg/kg/b.w. of nano-imidacloprid on biochemical blood profile in male rats for a duration of 60 d. Result: the exposure caused a significant decline in red blood cells (RBCs) and hemoglobin (H.b.) in all treated groups compared with the control, while causing an increase in blood platelets (PLT) and white blood cells (WBCs) in all rats treated as compared with the control rats. Furthermore, oxidative stress parameters

We conducted a study on the quality of non-diatom planktonic algae in the Tigris River during the autumn 2022 and winter 2023 seasons. The study focused on the impact of the medical city waste discharge to the Tigris River at three sites: Al-Sarafiya Bridge in the north, Medical City, and the Bab Al-Mu'adam Bridge in the south of Khader Elias. The study also examined some physical and chemical variables of the river water. Findings showed that there are 74 species (38 genera) of non-diatom algae in four orders. The blue-green algae Cyanophyceae and Chlorophyceae had the most species, with 35 species belonging to 19 genera and 16 genera per division, or 47% of all algae. Euglenophyceae had 5%, with 3 species and 2 genera, and Chrysophycea
