The impact of computer software on print advertising Design: an analytical study
The advertisement is no longer an idea designed and presented to the public. Rather, it has become instrumental in the process of achieving persuasion and attracting interest in the product and its worth. After the introduction of computer software for advertising, the elements and the technical aspects of advertising have become decisive in determining the success of any advertisement. As such, the problem that the research presents is based on a set of questions. The most important question is whether the level of manually executed advertisement are different from those based on the computer and whether they have any mental impact. The aim of the research is to detect the differences between the manual-based advertisement and the computer-based ones. lt also discusses operational techniques used in the computer-based advertisements. The researcher adopted the analytical descriptive method for analyzing the advertisement samples that reached 70 of the total research society (200 advertisements). The research offers a set of conclusions and recommendations. There is a clear variation in the level of manually executed advertisements and digitally executed advertisements in terms of design and output. There is also a need to adopt both old designing methods like having a painter, and modern methods based on computer graphics. The use of both modern techniques especially in the field of technical drawings and traditional techniques can result in worthy advertisements

Dual techniques of load shedding and capacitor placement considering load models for optimal distribution system
Voltage stability represents one of the main issues in electrical power system. Under voltage load shedding (UVLS) has long been regarded as one of the most successful techniques to prevent the voltage collapse. However, the ordinary load shedding schemes do not consider the different load models and decreasing in the economic cost that resulted from load disconnection, so the dual techniques of load shedding with reactive compensation are needed. Usually loads being modeled as constant power, while in fact of load flow the various load models are utilized. An investigation of optimal dual load shedding with reactive compensation for distribution system based on direct backward forward sweep method (DBFSM) load flow along with a comparison among the other load models are presented in this paper. The teaching learning-based optimization (TLBO) algorithm is executed in order to reduce power losses and enhance the voltage profile. This algorithm is tested and applied to IEEE-16 bus distribution test system to find the optimal superior capacitor size and placement while minimizing load shading for the network. Five different load shedding sequences are considered and the optimization performance of load models demonstrated the comparison through MATLAB program
Optimum reactive power compensation for distribution system using dolphin algorithm considering different load models
The distribution system represents the connection between consumers and the entire power network. The radial structure is preferred for distribution system due to its simple design and low cost. The electrical distribution system suffers from problems of rising power losses higher than the transmission system and voltage drop. One of the important solutions to improve the voltage profile and to reduce the electrical distribution system losses is the reactive power compensation which is based on the optimum choice of position and capacitor size in the network. In this paper, different models of electrical loads such as constant power(P), constant current(I), constant impedance(Z), and composite (ZIP) model are implemented with comparisons between them in order to identify the most effective load type that produces the optimal settlement for alleged loss reduction ,enhancement of the voltage profile, and cost savings. To minimize search space, Dolphin Optimization Algorithm (DOA) is applied for selecting the size and location of capacitors. Two case studies (IEEE 16- bus and 33- bus) are employed to evaluate the different load models with optimal reactive power compensation. The results of comparison between the different load models show that ZIP model is the best to produce the optimum solution for capacitor position and size. In addition, comparison of results with literature works are done and showed that DOA is the most robust among other algorithms to achieve the optimum solution for voltage profile enhancement significant reduction of losses, and saving cost

Dual technique of reconfiguration and capacitor placement for distribution system
Radial Distribution System (RDS) suffer from high real power losses and lower bus voltages. Distribution System Reconfiguration (DSR) and Optimal Capacitor Placement (OCP) techniques are ones of the most economic and efficient approaches for loss reduction and voltage profile improvement while satisfy RDS constraints. The advantages of these two approaches can be concentrated using of both techniques together. In this study two techniques are used in different ways. First, the DSR technique is applied individually. Second, the dual technique has been adopted of DSR followed by OCP in order to identify the technique that provides the most effective performance. Three optimization algorithms have been used to obtain the optimal design in individual and dual technique. Two IEEE case studies (33bus, and 69 bus) used to check the effectiveness of proposed approaches. A Direct Backward Forward Sweep Method (DBFSM) has been used in order to calculate the total losses and voltage of each bus. Results show the capability of the proposed dual technique using Modified Biogeography Based Optimization (MBBO) algorithm to find the optimal solution for significant loss reduction and voltage profile enhancement. In addition, comparisons with literature works done to show the superiority of proposed algorithms in both techniques
Immunohistochemical and Molecular Studies of p53 and KRAS Protein and Their Relations to Colorectal Carcinoma
The study inc1uded 50 tissue blocks embedded in paraffin wax (16 females and 34 males), obtained from a patients group with (CRC) colorectal cancer , as well as 35 Tissue blocks that were embedded in paraffin wax from norma1 co1on (ulcerative co1itis) as controls. A relatively few oncogenes and most prominently tumor-suppressing genes, Kirastien rat sarcoma virus (KRAS), and P53 genes have been mutated into a significant part of CRCs, and a broad collection of mutated genes has been defined in CRC subsets. Current findings showed very significant differences between patients and control subjects in the p53 positive rate (P<0.001). TP53 Pro/Pro genotype positivity was higher in the contro1 group I than in the patient group I and this was a significant difference (Pi<0.001) with an odd ratio of less than one. The genotype Pro/Pro was considered to be protective against colorectal carcinoma preventively fractured 0.767. The positive rate of p53 Arg/Arg genotype in patients was more frequent and statistically significant (P <0.01), because the odd ratio was more than one. The genotype Arg/Arg would be considered a colorectal carcinoma risk factor. We conclude that p53 over expression is used as an indicator of p53 mutation (as identified by immuno-historic chemistry) and KRAS protein expression was negatively impaired for all the patients in the current study
Minimization of Loss in Small Scale Axial Air Turbine Using CFD Modelling and Evolutionary Algorithm Optimization
Small scale axial air driven turbine (less than 10 kW) is the crucial component in distributed power generation cycles and in compressed air energy storage systems driven by renewable energies. Efficient small axial turbine design requires precise loss estimation and geometry optimization of turbine blade profile for maximum performance. Loss predictions are vital for improving turbine efficiency. Published loss prediction correlations were developed based on large scale turbines; therefore, this work aims to develop a new approach for losses prediction in a small scale axial air turbine using computational fluid dynamics (CFD) simulations. For loss minimization, aerodynamics of turbine blade shape was optimized based on fully automated CFD simulation coupled with Multi-objective Genetic Algorithm (MOGA) technique. Compare to other conventional loss models, results showed that the Kacker & Okapuu model predicted the closest values to the CFD simulation results thus it can be used in the preliminary design phase of small axial turbine which can be further optimized through CFD modeling. The combined CFD with MOGA optimization for minimum loss showed that the turbine efficiency can be increased by 12.48% compare to the baseline design
Biocompatibility of Newly Prepared Nanocalcium Oxide Based Root Canal Sealer (In Vivo study)
Aims: To evaluate in vivo the biocompatibility of newly prepared calcium oxide-based nanosealer. Materials and Methods: Twenty albino healthy male rabbits were used, each received three polyethylene tubes; one filled with BioRoot sealer (+ve control), one received the newly prepared nanosealer, and the last left empty served as (-ve control) were implanted in the corresponding skin pockets made at the dorsal skin of the anesthetized rabbits. Then the rabbits divided into four equal groups according to the observation periods. Tissue biopsies were collected at (3, 7, 14, and 28) day after the implantation. The specimens were processed and stained with hematoxylin and eosin and examined microscopically. Statistical analysis was performed by Kruskal Wallis and Mann-Whitney tests for analyses the inflammatory tissues response of each group at observation times. Results: Histopathologically; at 3 days (-ve) and (+ve) control groups revealed sever inflammatory reaction, while the experimental group represented moderate tissues inflammation. These inflammatory tissues reactions were reduced over times for all group until subsided completely at 28 days but still faster for experimental sealer. All groups revealed thin full organized fibrous capsule at 28 days representing the tissues tolerance of implanted materials. Statistically the experimental nanosealer represented the least inflammatory tissue reaction among groups. There were no statistically significance differences in fibrous capsule thickness among the groups. Conclusions: The prepared nanosealer represented high biocompatibility than other groups
