The present study aimed to identify the extent to which the content of social and national studies courses was included in interactive thinking maps in the educational stages in the Kingdom of Saudi Arabia, and to achieve the goal of the study, the researcher used the descriptive and analytical approach, and the study tool used consisted of a content analysis card; Where it included a list of the types of thinking maps, where the study sample consisted of all social and national studies courses at the elementary and intermediate levels, and it is (12) books for the student in its first and second parts, and after verifying the validity and reliability of the tool, it was applied to the study sample, and the study reached conclusions, including: The percentage of inclusion focused Thinking maps at the school level, each of the intermediate stage in the first and second semesters (54.9%), followed by the elementary stage (45.1%). The percentage of inclusion of thinking maps at the level of classroom arrangement in the first semester of elementary school ranked first with a percentage (30.6%), and with a high degree of availability, followed by the first and second semester of intermediate school in second place with a percentage (28.9%), (26.0) %), With medium availability, then the rest of the chapters with low availability. The order of thinking maps came in first place: the tree map was ranked first, with a total inclusion percentage in the primary and middle stages (37.0%), with a high degree of availability, then the flow chart came in second place with a percentage (19.7%), with a medium degree of availability, followed by the rest of the thinking maps with a degree Low availability. The study recommended that thinking maps should be included in a balanced and in-depth manner in all social and national studies courses at the different educational stages and more broadly, to conduct similar studies on different educational stages and other decisions.

Visual pollution is one of the major obstacles that affect the process of urban development. This study addressed one of the environmental pollutants that humans feel and live with and has become part of their daily lives. In 2003, this research aims to identify the manifestations of visual pollution and its causes and effective solutions to reduce them. for the city dwellers. One of the most common causes of visual pollution in the city of Al-Dura (Abu Dashir) is the spread of waste and garbage due to the lack of environmental awareness, and the abundance of billboards and the difference in the colors of building covers and their design, which means the marginalization of the additional environmental aspect. for the course city as well as

The complexity of supporting tissue structure makes the regeneration a challenge for periodontists. Early investigations were focused on discovering therapeutic substitutes that are biocompatible, simple to prepare and economic. This might cause a local release of growth factors that accelerate the healing process of the soft and hard tissue. Recently, platelet-rich fibrin (PRF) has received a wide attention as a biocompatible regenerative material in both dental and medical fields. PRF is a natural fibrin-derived biomaterial, and it is easy to obtain. It can be gotten from individual blood without the use of any external anticoag

The study aims at showing the role of tax audit in Impact the quality of tax statements. Tax audit is one of the most important means used by tax management to identify taxable revenues in a just, fair manner. The quality of statements relies on the extent to which the information provided by taxpayers is true and accurate. Tax audit works is compatible with the strategy of increasing tax adherence and detecting non-adherence cases and penalizing those who commit such violations. The study reached a number of results and conclusions. One of the most important results is that tax audit helps improve the information content of the taxpayers tax statements. This leads to recalculating taxable incomes and re-fixing t

This research aims to distinguish the reef environment from the non-reef environment. The Oligocene-Miocene-succussion in western Iraq was selected as a case study, represented by the reefal limestone facies of the Anah Formation (Late Oligocene) deposited in reef-back reef environments, dolomitic limestone of the Euphrates Formation (Early Miocene) deposited in open sea environments, and gypsiferous marly limestone of the Fatha Formation (Middle Miocene) deposited in a lagoonal environment. The content of the rare earth elements (REEs) (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Er, Ho, Tm, Yb, Lu, and Y) in reef facies appear to be much lower than of those in the non-reef facies. The open sea facies have a low content of REEs due to bein

In this paper, an algorithm through which we can embed more data than the
regular methods under spatial domain is introduced. We compressed the secret data
using Huffman coding and then this compressed data is embedded using laplacian
sharpening method.
We used Laplace filters to determine the effective hiding places, then based on
threshold value we found the places with the highest values acquired from these filters
for embedding the watermark. In this work our aim is increasing the capacity of
information which is to be embedded by using Huffman code and at the same time
increasing the security of the algorithm by hiding data in the places that have highest
values of edges and less noticeable.
