Synthesis and Characterization of Black Currant Selenium Nanoparticles (Part I)
...Show More Authors

The present study aimed to synthesize selenium nanoparticles (SeNPs) using aqueous extract of black currant as a reducing agent. The green synthesized black currant selenium nanoparticles (BCSeNPs) were identified by color change. The characterization of SeNPs was achieved by Ultraviolet-visible (UV–VIS) spectroscopy, scanning electron microscopy (SEM), X–ray diffraction analysis (XRD), and Fourier transform infrared spectroscopy (FTIR). These tests were used to detect: stability, morphology, size, crystalline nature, and functional groups present on the surface of BCSeNPs. The results revealed appearance of the brick-red color indicating the specific color of selenium nanoparticles, and UV-Vis spectroscopy showed band absorbance at 265 nm of intense surface plasmon resonance manifesting the formation and stability of the prepared BCSeNPs. The SEM image showed the prevalence of spherical selenium nanosized, XRD at 2θ revealed crystallin selenium nanoparticles, the size was in the average of 18-50 nm. Furthermore, FTIR revealed the presence of functional groups of the plant which act as stabilizing and reducing agents. In conclusion, the aqueous black currant extract can act as a reducing and capping agent to synthesize BCSeNPs in nano-scale size by a simple method

Synergistic Effect of Ag <sub>2</sub> O@CuO Photocatalyst in Engineering Highly Hydrophilic Photocatalytic Membranes With Superior Self‐Cleaning Properties for Organic Dyes Elimination
...Show More Authors
ABSTRACT<p> Polyvinyl chloride (PVC) ultrafiltration membranes were efficiently fabricated using a (0.1–0.5 wt.%) Ag <sub>2</sub> O@CuO heterojunction photocatalyst to form a PVC/Ag <sub>2</sub> O@CuO photocatalytic membrane (PM) stimulated by UV light. The PVC/Ag <sub>2</sub> O@CuO PM fabricated using the phase inversion process resulted in significant improvement in internal morphology, porosity, pure water flux, and separation efficacy of the doped membranes. The efficacy of the PVC/Ag <sub>2</sub></p> ... Show More

Abstract<sec><title>Background

There is a growing interest in studying the effects of arthritis on a person's work productivity using a growing variety of outcome indicators.

Objectives

To develop a valid and reliable shortened version of the Workplace Activity Limitation Scale 12 (WALS‐12) for assessing work productivity limitations in rheumatoid arthritis (RA) patients.

Methods

A cross‐sectional study involving 277 RA patients was conducted. An exploratory factor analysis on WALS‐12 was used for item reduction on the first sample. Then confirmatory factor ana

The extent to which the Iraqi environment responds to the requirements of IAS 12 in determining income tax: بحث تطبيقي في الهيئة العامة للضرائب/ قسم الشركات
...Show More Authors

The importance of this research comes from the possibility of achieving positive interaction between accounting and tax through the interest in setting accounting standards and adapting them to local tax legislation, as the adoption of the application of the international standard (IAS 12) for income taxes helps to measure and determine the base for income tax and may lead to an increase in the tax outcome. Through the reliance of enterprises on many accounting bases, and that the tax administration in Iraq depends on the element of personal judgment in determining the tax base, which leads to lack of objectivity in determining the tax outcome, as the impact of the accounting standard (IAS 12) on the tax base and tax outcome is one of th

Amis: NAFLD is considered to be the most common cause of liver conditions worldwide. Also, it is a primary reason that leads to coronary artery diseases, limiting blood flow to the heart. Therefore, This study aimed to evaluate the serum level of Nesfatin-1 and its ability to indicate the prognosis of CAD in patients with NAFLD. Material & Methods: one-hundred eighty Individuals were enrolled in the study, including In both genders, blood was collected from each Individual and sent to the laboratory for biochemical tests. Findings: Data from the current study showed a significant increase in Nesfatin-1 in the CAD group and a significant decrease in Nesfatin-1 in the NAFLD group compared to the control group. In addition, there w
