The picture has taken a place that sometimes enables it to take precedence over media analysis، psychology، and political communication.
The image has the ability to influence to obtain persuasion، not only emotionally or
dramatically، but also on the level of commercial and political persuasion. In every
image، the intention of that persuasion is hidden.
It can be identified by a set of underlying dimensions such as vitality، social dominance، and confidence، for which a group of specific suggestions or movements، such
as a smile، the movement of hands، or the nature and way of looking with the eyes، is
established. The visual image often precedes its verbal counterpart in the proce

The mechanical properties and microstructure of hot-rolled steel are critical in determining its performance in industrial applications, particularly when exposed to elevated temperatures. This study examines the effects of varying temperatures and soaking times on these properties through a series of controlled experiments. The primary objective was to optimize the key response parameters, including tensile strength, yield strength, and elongation, by analyzing the influence of temperature and time. A full factorial design approach was used, applying the desirability function theory to explore all possible combinations and identify optimal processing conditions. The experimental results showed that the soaking time played a critica

Due to the high mobility and dynamic topology of the FANET network, maintaining communication links between UAVs is a challenging task. The topology of these networks is more dynamic than traditional mobile networks, which raises challenges for the routing protocol. The existing routing protocols for these networks partly fail to detect network topology changes. Few methods have recently been proposed to overcome this problem due to the rapid changes of network topology. We try to solve this problem by designing a new dynamic routing method for a group of UAVs using Hybrid SDN technology (SDN and a distributed routing protocol) with a highly dynamic topology. Comparison of the proposed method performance and two other algorithms is simula

In the present work, radon gas concentrations in different surface soil samples in Baghdad governorate were measured using RAD-7 detector. The results have been shown that, the Radon gas concentrations ranged between (41.67±1.78Bq/m3), to (185.67±4.22Bq/m3), a map showing the distribution of the concentration of radon in selected areas was defined to identify areas with high pollution level. The reason for the high concentration of radon is that these surface soil samples are taken from agricultural areas. It is also known that fertilizers contain uranium levels as well as areas bombed in wars in the country. It is worth noting that all radon concentrations in Baghdad governorate are below the recommended minimum of 200-300Bq/m3) (Inte

This research demonstrates an efficient method for the synthesis and storage of molecularly imprinted polymers (MIP) using bulk polymerization of Pregabalin (PGB), which is carried out at room temperature. This method has the advantages of high sensitivity, low cost, increased stability, and longer lifetime of the polymers. The research used specific ratios between template, monomer, and cross-linking agents to ensure suitable adsorption capacity. Benzoyl peroxide (BPO) was used as an initiator for the functional monomer styrene and ethylene glycol dimethacrylate (EGDMA) cross-linking to create the MIP of Pregabalin (PGB-MIP). The molecularly imprinted polymer was studied using ultraviolet-visible spectroscopy (UV-VIS) a

This study experimentally investigated Free-Fall Gravity Drainage (FFGD) under combination-drive conditions in a two-dimensional Hele-Shaw model representing a water-drive reservoir. An initially high gravity potential from the oil column enabled early oil drainage before aquifer support became dominant. Three water-drive strengths were tested, demonstrating that a stronger aquifer (1.15 psig) accelerated oil recovery to approximately 75% of the original oil in place (OOIP) within 60 minutes, resulting in a final recovery of 79.5%. However, this was accompanied by rapid water breakthrough after 2.5 minutes and high-water cuts exceeding 90%. In contrast, a weaker aquifer (0.725 psig) stabilized the oil–water contact

In this study presents a numerical investigation of natural convection heat transfer in an annular enclosure partially filled with metal foam. The inner cylinder is maintained at a constant temperature, while the outer cylinder is subjected to a uniform heat flux; both vertical sidewalls are thermally insulated. The fluid flow is modeled using the Navier–Stokes equations under the Boussinesq approximation, and the porous medium is described by the Brinkman–Forchheimer Darcy model, assuming local thermal equilibrium. Simulations are conducted using ANSYS FLUENT to examine the effects of pore density (10 PPI and 40 PPI), inclination angle (0°, 30°, 60°, 90°) and Rayleigh number (10⁴ ≤ Ra ≤ 10⁶) on thermal p

This study evaluates the performance of Self-Compacting Engineered Cementitious Composites (SCC-ECC) under standard 28-day water curing, aiming to develop a mixture with optimal flowability, high mechanical strength, and enhanced durability. Twenty-seven SCC-ECC mortar mixtures (without coarse aggregate) were prepared and tested according to EFNARC (2002) guidelines for self-compacting mortars. Fresh results (slump flow 240–260 mm, V-funnel 6–12 s, L-box >0.80) confirmed adequate flowability. In addition, direct tensile tests on dog-bone specimens demonstrated strain-hardening with multiple fine cracks and strain capacity exceeding 2%, verifying the ECC behavior. The mixtures were prepared with varying fly ash con

In this paper two main stages for image classification has been presented. Training stage consists of collecting images of interest, and apply BOVW on these images (features extraction and description using SIFT, and vocabulary generation), while testing stage classifies a new unlabeled image using nearest neighbor classification method for features descriptor. Supervised bag of visual words gives good result that are present clearly in the experimental part where unlabeled images are classified although small number of images are used in the training process.

Background: Dental caries is generally given the highest priority in national oral health services for adult populations. Yet, there is no study which has explored the impact on quality of life specifically related to dental caries in samples of dental students. The purpose of the current study was to assess the impact of caries experience on quality of life among dental students in three governorates in Iraq. Materials and Methods: This observational study included 1364 dental students aged 18–22 years old, from three governorates. Information on quality of life was obtained from a structured, self-administered questionnaire from the students who were willing to participate in the study. The data was collected, summarized and sta

The relationship between cinema and architecture has witnessed an increasing presence in contemporary studies, as both converge at a common point: shaping human experience within a specific temporal and spatial space. Cinema uses the principles of rhythm, sound, and memory to shape visual and auditory narratives, while architecture seeks to embody these principles in tangible spaces that organize human movement and influence sensory and emotional perception. This relationship demonstrates that cinematic expression tools can enrich architectural experience. However, the challenge lies in the limited theoretical frameworks that explain how to translate these principles into design strategies, particularly in cultural archi

The process of drilling wells has become more complex today due to greater depths and advanced drilling techniques. Therefore, obtaining ideal specifications for drilling fluids has become of great importance to overcome drilling problems and reduce costs. Therefore, studies have begun to investigate the effect of nanomaterials on drilling fluids. This study is an investigation into the effect of nano-iron oxide on drilling fluid specifications.

         The Na-alginate bead is commonly used in biotechnology fields such as adsorption due to ion exchange between Ca and Na with elements. Scanning electron microscopy (SEM-EDX) has proven to be a comparative method in the detections of these adsorbed elements, but the un-flat forming area of beads that can introduce impossible of the detection of element adsorbed. In contrast, X-ray fluorescence (XRF) documents analysis of elements, direct examination, which may analysis the adsorbents of elements. Here, this Study evaluated the possibility by using XRF for the direct analysis for examples of Cd and Ag in a bench stand. This Study compared this to commonly use

Apical periodontitis (AP) is the most prevalent chronic inflammatory disease of the teeth. Bone resorption dynamics in symptomatic and asymptomatic AP are still unrecognized. This study examined different inflammatory markers within gingival crevicular fluid, including matrix metalloproteinases 8 (MMP8), tissue inhibitors of metalloproteinases 1 (TIMP1), receptor activator of nuclear factor κB (RANK), its ligand (RANKL), and osteoprotegerin (OPG), to be used in comparing symptomatic apical periodontitis (SAP) and asymptomatic apical periodontitis (AAP) versus healthy teeth. Subjects with SAP, AAP, and a control group were recruited and GCF samples were collected by Periopaper strips. Clinical and radiographical measures were used f

One way to synthesis texture in a fast and easy way is image quilting proposed by Efros and Freeman in
2001. This research brings the adaptive search power of genetic algorithm and combines it with the
concept of image quilting to propose new texture synthesis algorithm. The proposed GA is ran on many
different images from standard texture sets. Visual comparison of our proposed GA with image quilting
algorithm is considered. The texture results generated by the proposed GA are roughly comparable in
quality to those generated from Efros and Freeman algorithm.
