public relations at Al-Shuhadaa Establishment: an analytical study of social networking sites and the website) came to know and monitor the contents of social networking sites for Al-Shuhadaa Establishment, the research problem was represented by the main question: (What is the effectiveness of social networking sites and the website of Al-Shuhadaa Establishment) ,This research was classified within the descriptive research, and the two researchers adopted the survey method in order to achieve the objectives of the research, and they used the tool: content analysis as a research tool, the analysis of the contents included the official website of the establishment (Instagram page), and other social networking sites that Al-Shuhadaa Establishment communicate with its audience, and the content analysis included publications for the period from 1/7/2021 to 31/7/2021, which amounted to 48 publications. The research several results, the most important of which were: 1-The news of the general managers comes first in the institution's publications on Instagram page. 2-The establishment does not respond to most of the questions and inquiries from the public that they raise through comments on its publications, as it did not answer about 400 questions during the research period. 3-he presence of several pages on Facebook by the name (Al-Shuhadaa Establishment) and identifying itself as a governmental organization. 4-The unofficial pages bearing the name of the institution on Facebook obtain more interactions from the public than the official page of the establishment. 5-The lack of knowledge of those in charge of managing the social networking sites in the establishment about the newsletter and cultural magazine , and the issuance of the guide.
The paper aims to propose the maximum track length (Lmax) measurement as an alternative approach to evaluate and extract the bulk etch rate (Vb) of the nuclear detector PADC CR-39, and compare it with the results obtained by the removal layer thickness measurement of the etched detector. The alternative Lmax-method mainly relies on the measuring the length of the etched tracks, their maximum values and saturation times from the obtained track profile images. The detectors were irradiated with different energies of alpha particles emitted from the 241Am source and then etched in a 6.5 N NaOH solution at 70±1oC for different successive time intervals. In

Rheumatoid arthritis (RA) is a chronic inflammatory polyarithritic disease
associated with remission and exacerbation with different immunological
features.Rheumatoid factor(RF) screening test was used quantitatively and qualitatively
using an enzyme immunoassay (EIA), RF-isotypes (RF-IgG, RF-IgM, RF-IgA) ,
Interleukin-18 (IL-18) and Interleukin – 18 binding protein (IL-18BP) were detected
quantitatively usingenzyme linked immunosorbent assay(ELISA). Results indicated a
51% positivity in RF among RA patients and a prevalence of the RF-isotype (RF-IgM)
with the highest level at (41.6±16.3 U/ml) (p < 0.05) among other RF-isotypes at a
percentage of 85.5% , results also indicatedan elevated serum level of IL-18
This research evaluates the optical properties of an inhomogeneous and non-paraxial system using a solar ball lens (SBL) as a new thermal solar concentrated collector. This evaluation is based on detecting a diacaustic curve in a straightforward and accurate manner, with the diagnostic relying on image processing as a computational tool using the MATLAB program rather than a complicated numerical analytic procedure. The circle of least confusion (CLC) of the (SBL), (Fluorinated ethylene propylene (FEP) polymer – water core), was calculated. Furthermore, the study evaluated the maximum geometrical concentration ratio (G C) of refracted solar radiation that can be captured by a receiver of the (SBL). Without energy losses due

In the current research, we investigated the absorption spectrum for R590 and C480 dyes in ethanol solvent for different dye solution concentrations of 10-4, 10-5 and 10-6M. These dyes have been prepared and studied before and after gamma irradiation (first, second ionization) using cesium-137 source with absorbed doses of 18.36 Gy (time exposure of 10 days) and 73.44 Gy (with time exposure of 40 days). We noticed that the absorption intensity was decreased with decreasing concentration, before gamma irradiation while the absorption spectrum peak shifted towards the short wavelength (blue shift). It was also found that the intensity of absorption spectrum increased and shifted the absorption spectrum peak towards the long wavelength (red

Through an experimental program of eighteen specimens presented in this paper, the bond strength between reinforcing bar and rubberized concrete was produced by adding waste tire rubber instead of natural aggregate. The fine and coarse aggregate was replaced in 0%, 25%, and 50% with the small pieces of a waste tire. Natural aggregate replacement ratio, rebar size, embedded rebar length, the rebar yield stress of rebar, cover, and concrete compressive strength were studied in this investigation. Ultimate bond stress, bond stress-slip response, and failure modes were presented. The experimental results reported that a reduction of 19% in bond strength was noticed in 50% replaced rubberized concrete compared with convention

The study seeks to investigate the effect of Dunn Dunn learning style model on students’ achievement. Besides, the way of developing students’ deductive thinking by testing the null hypothesis: there is no significant difference between experimental group who takes Dunn Dunn model as style in studying geography and control group that follows a traditional method in studying geography at the level of (0,05). Additionally, there is no significant difference between experimental group who takes Dunn Dunn model as style in studying geography and control group that follows a traditional method in studying geography at the level of (0,05) on testing developing deductive thinking skills. The researcher adopted a quasi-experimental posttest

Electrospun nanofiber membranes are employed in a variety of applications due to its unique features. the nanofibers' characterizations are effected by the polymer solution. The used solvent for dissolving the polymer powder is critical in preparing the precursor solution. In this paper, the Polyacrylonitrile (PAN)-based nanofibers were prepared in a concentration of 10 wt.% using various solvents (NMP, DMF, and DMSO). The surface morphology, porosity, and the mechanical strength of the three prepared 10 wt.% PAN-based nanofibers membranes (PAN/NMP, PAN/DMF, and PAN/DMSO) were characterized using the Scanning Electron Microscopy (SEM), Dry-wet Weights method, and Dynamic Mechanical Analyzer (DMA). Using DMF as a solvent resulted in a lon
