This study comprised three traverses extending parallel through the Northern, Central and Southern Mahmudiya districts, and perpendicular to the course of the Euphrates River. They were identified to collect (15) soil samples and some water samples as distributed within the land cover classes of the study area. Those classes were determined by visual interpretation and supervised classification for Landsat (TM) images obtained in August/2007. The digital classification was based on Maximum Likelihood method using six spectral bands excluding the thermal band. Chemical and physical laboratory analysis for the soil characteristics was performed to determine the types of land degradation in the study area.
The results showed that the highest percentage of degradation is related to the chemical degradation type having a percentage of (85.71%). It is distributed in the land areas of very height values of calcium carbonate, salinity and alkaline contents, with low values of organic material, total nitrogen and phosphorus. In the other hand the percentage of the physical degradation type was (14.29%) due to higher values of bulk density.

The Ottomans ruled Turkey for nearly six centuries, during which the Ottoman Empire passed through varying periods in terms of strength, influence, and the area of land they ruled. In the last decade of its rule, the Ottoman Empire was severely weakened in all political, military, administrative and economic aspects. In addition to the internal strife that was stirred up by the leaders of the Association (Union and Progression), that organization that led the coup movement against the Ottoman Empire later.
After the abolition of the Sultanate and the proclamation of the Turkish Republic, the social fabric in Turkey changed, and many customs and traditions alien to it emerged to society. One of the thing

Higher education is one of the foundational pillars that contributes to the development of societies and the achievement of social and economic progress. With the accelerating advancements in technological, environmental, and social fields, universities and educational institutions worldwide are facing significant challenges requiring them to adapt to these changes and develop new educational strategies. In this context, directing higher education towards achieving sustainable development goals (SDGs) has become imperative, as these goals are now an integral part of modern societies' vision, particularly in light of global challenges such as climate change, population growth, and unemployment. By the year 2050, educational institutions

The heating is simulated by a centrally located heat source on the bottom wall, and four different values of the dimensionless heat source length, 1/5, 2/5, 3/5, 4/5 are considered. The laminar flow field is analyzed numerically by solving the steady, two-dimensional incompressible Navier-Stokes and energy equations. The Cartesian velocity components and pressure on a collocated (non-staggered) grid are used as dependent variables in the momentum equations discretized by finite volume method; body fitted coordinates are used to represent the trapezoidal enclosure, and grid generatio

During recent decades, hundreds of thousands of Iraqis lost their lives as a result of wars, economic blockade, or acts of violence and terrorism. The loss of a family member, especially husband makes women suddenly bears full responsibility for the family. Lost could impose new changes in psychological, social, and economical roles. These changes usually combine with the negative effects aftermath the lost trauma. Some of the reports in Iraq showed there were increased and huge numbers of widows and orphans. This study aimed to identify the aspects of Posttraumatic Growth (PTG) in Iraq women who lost their close relatives (especially husbands). 52 of Iraqi women who lost their husband and 49 women who experienced other traumatic events
