Comparative Study of Activated Carbon and Silver Nanoparticle-Loaded Activated Carbon Derived from Tea Waste for Removal of Tetracycline from Aqueous Solution
...Show More Authors

The present work elucidates the utilization of activated carbon (AC) and activated carbon loaded with silver nanoparticles (AgNPs-AC) to remove tetracycline (TC) from synthetically polluted water. The activated carbon was prepared from tea residue and loaded with silver nanoparticles. Scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and Brunauer-Emmett-Teller (BET) were used to characterize the activated carbon (AC) and silver nanoparticles-loaded activated carbon (AgNPs-AC). The impact of various parameters on the adsorption effectiveness of TC was examined. These variables were the initial adsorbate concentration (Co), solution acidity (pH), adsorption time (t), and dosage of the adsorbent. The maximum TC removal percentage was (88%) at pH = 9, time = 230 min, Co = 60 ppm, and dosage = 0.39 g/25 ml using AC as an adsorbent. Whereas the maximum TC removal percentage was (98%) at pH = 9, time = 46 min, Co = 60 ppm, and dosage = 0.0406 g/25 ml using AgNPs-AC. The isotherm models were also studied. It was found that the Langmuir isotherm model fitted well with the experimental data. The adsorption kinetics study showed that the pseudo-second-order accurately describes the experimental results. The analysis of the adsorption thermodynamics revealed that TC adsorption on TAC and AgNPs-AC was endothermic and spontaneous. The study aims to make activated carbon from tea waste and load silver nanoparticles on that activated carbon (AgNPs-AC). It also studies how two adsorbents (activated carbon and activated carbon loaded with silver nanoparticles) remove tetracycline from artificially polluted water. Then, the outcomes were compared.

The Salivary Inflammatory Biomarkers (Interleukin-6, C - reactive protein) in Relation with Caries-Experience among a Group of 12 Year Old Obese Boys
...Show More Authors

Background: Obesity and dental caries are multifactorial diseases related to poor eating habits and show a close relationship with the sociodemographic characteristics of individuals presenting these diseases. This research aimed to investigate the severity of dental caries among group of obese boys aged 12 year in relation to salivary interleukin-6 (IL-6) and C-reactive protein (CRP) of unstimulated whole saliva in comparison with normal weighted boys of the same age. Materials and Methods: The study group included 40 obese boys, with an age of 12 year. The control group included 40 normal weighted boys of the same age. The total sample involved for nutritional status assessment using Body Mass Index specific for age and gender according t

Clients' Satisfaction with Nursing Services by Using the Patient Satisfaction with Nursing Care (PSNCS): An Applied Research in some of Baghdad Teaching Hospitals
...Show More Authors

Abstract:

     This study aims to identify the level of patients’ satisfaction among a sample of hospitalized patients in the targeted hospital (Al-Kindy Teaching Hospital, and Al-Yarmook Teaching Hospital). Moreover, this study highlights the reality of services for patients, especially in the targeted governmental teaching hospitals. The Patient Satisfaction with Nursing Care (PSNCS) has been measured in these hospitals through the revised scale by Tang et al, (2013).This scale includes four major domains; Health Information (5 items), Influencing Support (4 items), Decision Control (4 items), Specialized Technical Competence (7 items). The method of surveying patients’ opinions about the degree

Violet Laser Irradiation Effect on The Optical Properties of Cobalt oxide (CoO<sub>2</sub>) Thin Films deposited via Semi-Computerized Spraying System
...Show More Authors
Abstract<p>The existing investigation explains the consequence of irradiation of violet laser on the optic properties of (CoO<sub>2</sub>) films. The film was equipped by the utilization of semi-computerized spray pyrolysis technique (SCSPT), it is the first time that this technique is used in the preparation and irradiation using a laser in this technique. From the XRD analysis, the crystalline existence with trigonal crystal system was when the received films were processed by continuous violet laser (405 nm) with power (1W) for different laser irradiation time using different number of times a laser scan (0, 6, 9, 12, 15 and 18 times) with total irradiation time(0,30,45,60,75,90 min</p> ...

A Novel Single Nucleotide Polymorphism of Interleukin-10 Gene is Linked to Type 2 Diabetes Mellitus in Iraqi Patients with Toxoplasmosis(Conference Paper )#
...Show More Authors

Type 2 diabetes mellitus (T2DM) is a chronic disorder that is a serious health concern all over the globe, it is linked to Interleukin-10 (IL-10) single nucleotide polymorphisms (SNPs) at the promoter region. On the other hand, diabetes influences the cellular and humoral immunity predisposing the patient to a variety of opportunistic parasites one of them is Toxoplasma gondii (T. gondii), which may infect any nucleated cell, including pancreatic cells. The purpose of this research was to explore the association of IL-10 genetic polymorphisms with T2DM and latent toxoplasmosis among Iraqi patients with T2DM. Fifty-five and fifty-eight venous blood samples were taken from T2DM patients and age-matched non-diabetic person

FIRST RECORD OF THE LARGE-BILLED CROW CORVUS MACRORHYNCHOS WAGLER, 1827 PREDEATING ON THE VULNERABLE INDIAN ROOFED TURTLE PANGSHURA TECTA (GRAY, 1831) IN INDIA
...Show More Authors

The Vulnerable Indian Roofed Turtle Pangshura tecta (Gray, 1831) (Testudines: Geoemydidae) occurs in the Sub-Himalayan lowlands of India, Nepal, Bangladesh, and Pakistan. Little is known about its natural history, no studies have been conducted revealing its natural predators. In this study, a group of Large-billed Crow Corvus macrorhynchos Wagler, 1827 (Passeriformes: Corvidae) was observed hunting and predating on an Indian Roofed Turtle carcass in the bank of river Kuakhai, Bhubaneswar, India. The first record of this predation behaviour is reported and substantiated by photographic evidence.
