The study concludes that achieving visual persuasion in journalistic news websites is a complex process that requires the responsibility of the designer

The Visual Rhetoric of The Image in The Treatment of Press News Sites for Environmental Initiatives

The study sought to identify the connotations of visual rhetoric in addressing the press news websites of the environmental initiatives Green Saudi Arabia . The sample was represented in (6) fixed press photos. The choice was taken to be rich in symbols, connotations, signs and semiotic icons that help reveal the underlying meanings. Their selection on news sites (Okaz, Madam, previously), with two images from each site, during 2021, the year in which His Highness, the Saudi Crown Prince “Mohammed bin Salman” announced the “Green Saudi Arabia” initiative and analyzed them qualitatively by dismantling the components of the images. For (visual elements, rhetorical forms, graphic foundations), To reach the underlying connotations and meanings that visual rhetoric seeks to convey to the target audience, by using the media survey, semiotic, and it is quicker to persuade than words by presenting rational arguments for addressing the issues of environmental initiatives, visual rhetoric uses symbolism as a substitute for realism because it is more influential and more persuasive

Saudi Journalists Employing Artificial Intelligence Algorithms to Detect Fake News

The study aimed at quantitative monitoring and qualitative interpretation of the perceptions and attitudes of Saudi journalists, who are the study sample, towards the use of artificial intelligence algorithms in detecting false news. Saudi artificial intelligence algorithms rely on detecting false news, based on the media survey approach, both quantitative and qualitative, through the questionnaire tool to survey a sample of (35) Saudi journalists working in journalistic news sites in the Eastern Province. The study concluded, through what was confirmed by Rogers in the theory of the spread of new ideas, and what was concluded by Davis in the technology acceptance model, in the variation of expected reactions towards the introduction and use of technology in institutions. , that the spread and application of artificial intelligence algorithms in detecting false news depends on the extent of journalists awareness of these algorithms, their conviction in them, and the extent of their awareness of their benefits and advantages, and their need and use. And the need for international press institutions to keep up with and follow the successive developments in the use of these algorithms in detecting false news, in addition to the existence of some obstacles to their use, such as the lack of incentive methods for using these algorithms. Algorithms, the high cost of obtaining such software and the poor skills of journalists. The proportions of the respondents proposals converged to enhance the benefit from the need to provide the necessary technical infrastructure in all press institutions, benefit from global experiences, maximize the resources of press institutions, and establish clear policies for working using technologies that preserve property. Also take advantage of online self-learning resources

Numerical and experimental investigations on efficient design and performance of hydrokinetic Banki cross flow turbine for rural areas

Micro hydrokinetic energy scheme presents an attractive, environmentally-friendly and efficient electric generation in rural, remote and hilly areas. However, this scheme is yet to be fully discovered, as researchers are still searching for solutions for the main problems of low velocity of current in the open flow channels and low efficiency of hydrokinetic turbines. This research proposes a novel system configuration to capture as much kinetic energy as possible from stream water current. This system, known as bidirectional diffuser augmented (BDA) channel, functions by utilizing dual directed nozzles in the flow and is surrounded by dual cross flow/Banki turbines. It is also important to obtain the efficient design parameters of the turbines to use in the current configuration. The appropriate angle is important in order to guide the flow to touch the blades more perpendicularly to capture as much torque and power as possible. Hence, experimental and numerical investigations have been carried out in this research paper to study the performance characteristics of the CFT configuration applied in BDA system and investigate the effects of blades’ inlet and outlet angles of CFT runners on the internal flow characteristics and efficiency. In this study, four different runners with various inlet and outlet angles of two CFT have been investigated. The CFD results have been validated with the experimental work and proven acceptable with flow pattern and performance characteristics. The results of the current study conclude that the maximum power coefficients (Cp) of 0.612 and 0.473 for lower and upper turbines are recorded for best runner angles of Case 3

Metformin use in obese mothers is associated with improved cardiovascular profile in the offspring

BACKGROUND: Maternal obesity increases the risk for pregnancy complications and adverse neonatal outcome and it has also been associated with long lasting adverse effects in the offspring, including increased body fat mass, insulin resistance and increased risk for premature cardiovascular disease. Lifestyle interventions in pregnancy have produced none or modest effects in reducing adverse pregnancy outcomes in obese mothers. Metformin use in Obese Pregnant women trial was associated with reduced adverse pregnancy outcomes and had no effect on birthweight. However, the long-term implications of metformin on the health of offspring remain unknown. OBJECTIVE: The purpose of this study was to assess whether prenatal exposure to metformin can improve the cardiovascular profile and body composition in the offspring of obese mothers. STUDY DESIGN: In 151 children from the Metformin use in Obese-Pregnant women trial we measured body composition, peripheral blood pressure and arterial pulse wave velocity. Central hemodynamics (central blood pressure and augmentation index) were estimated using the Vicorder device. Left ventricular cardiac function and structure were assessed by echocardiography. RESULTS: Children were 3.9±1.0 years of age and 77 were exposed to metformin prenatally. There was no significant difference in peripheral blood pressure, arterial stiffness and body composition apart from gluteal and tricep circumferences which were lower in the metformin group (p<0.05). The metformin, compared to the placebo group, had lower central hemodynamics (mean adjusted decrease - 0.707mmHg for aortic systolic blood pressure, -1.65mmHg for aortic pulse pressure and -2.68% for augmentation index, p<0.05 for all) and lower left ventricular diastolic function (adjusted difference in left atrial area -0.525cm2, in isovolumic relaxation time -0.324msec and in pulmonary venous systolic wave 2.97cm/s, p<0.05 for all). There were no significant differences in metabolic profile between the groups. CONCLUSION: Children of obese mothers who were prenatally exposed to metformin, compared to those exposed to placebo, have lower central hemodynamic and cardiac diastolic indices. These results suggest that administration of metformin in obese pregnant women may potentially have a beneficial cardiovascular effect for their offspring

Silver-enriched ZnO:Ag thin films deposited by magnetron co-sputtering: Post annealing effects on structural and physical properties

The ZnO semiconductor is probably among the most mentioned compounds in the scientific literature during the last decade, which is mainly due to its wide spectrum of applications. Compounds based on ZnO (in doped or composite form) are of great relevance for the development of high-tech devices. In this work, we present the growth and characterization of samples deposited by DC Magnetron co-sputtering from two pure Zn and Ag targets in an O2 / Ar atmosphere. The samples were characterized as deposited and after an annealing treatment in a reducing atmosphere. We have used XRD, RBS, ellipsometry, UV visible photoluminescence, and electrical measurements for sample characterization. The results revealed the amorphization of ZnO when the Ag content increases and, after annealing, a mixture of crystalline phases was detected for the samples with higher Ag content. It is also demonstrated the strong effect of the presence of Ag atoms in the stimulated optical and electrical responses from ZnO:Ag compounds obtained in this wor

Quantitative microbial risk assessment of a non-membrane based indirect potable water reuse system using Bayesian networks

Indexación ScopusRisk-based approaches are used to define performance standards for water and wastewater treatment to meet health-based targets and to ensure safe and reliable water quality for desired end use. In this study, a screening level QMRA for a non-membrane based indirect potable reuse (IPR) system utilizing the sequential managed aquifer recharge technology (SMART) concept was conducted. Ambient removals of norovirus, Campylobacter and Cryptosporidium in advanced water treatment (AWT) steps were combined in a probabilistic QMRA utilizing Bayesian networks constructed in Netica. Results revealed that all pathogens complied with disease burden at the 95th percentile, and according to the assumptions taken about pathogen removal, Cryptosporidium was the pathogen with the greatest risk. Through systematic sensitivity analysis, targeted scenario analysis, and backwards inferencing, critical control points for each pathogen were determined, demonstrating the usefulness of Bayesian networks as a diagnostic tool in quantifying risk of water reuse treatment scenarios. © 2021 Elsevier B.V.https://www-sciencedirect-com.recursosbiblioteca.unab.cl/science/article/pii/S0048969721015308?via%3Dihu

Enhanced corrosion protection of Epoxy/ZnO-NiO nanocomposite coatings on steel

ZnO-NiO nanocomposite with epoxy coating on mild steel has been fabricated by the sol–gel assisted method. The synthesized sample was used to study corrosion protection. The analysis was performed by electrochemical impedance spectroscopy in 3.5% NaCl solution. The structural and morphological characterization of the metal oxide nanocomposite was carried out using XRD and SEM with Energy Dispersive Absorption X-ray (EDAX) analysis. XRD reveals the ZnO-NiO (hexagonal and cubic) structure with an average ZnO-NiO crystallite size of 26 nm. SEM/EDAX analysis of the ZnO-NiO nanocomposite confirms that the chemical composition of the samples consists of: Zn (8.96 ± 0.11 wt.%), Ni (10.53 ± 0.19 wt.%) and O (80.51 ± 3.12 wt.%). Electrochemical Impedance Spectroscopy (EIS) authenticated that the corrosion resistance has improved for the nanocomposites of ZnO-NiO coated along with epoxy on steel in comparison to that of the pure epoxy-coated steelThis research was funded by the Undergraduate Research Experience Program project no.
