Organizational learning is one of the most important means of human resource development in organizations, but most of the organizations, especially public ones do not realize the importance of organizational learning enough, and estimated his role accurately in building intellectual capital, the resource competitive importantly for organizations of the third millennium and who suffers is other end of lack of understanding of its meaning and how to prove its presence and measured in public organizations, so there is the need for this research, which aims to investigate the effect of organizational learning its processes (knowledge acquisition, Information transfer, Interpreting the information, Organizational memory) in building intellectual capital in public organizations through its componets (The human capital, The structural capital ,Capital of customers ,the creative Capital) comparative research between the universities of Baghdad and al-Mustansiriya , through three main Hypotheses branched from them ten Sub-hypotheses to compare between the two organizations and to know the relationship between and the impact of the two variables of the research through many of the Statistical methods , has been using the questionnaire as a tool for data collection, with a number of (174) teaching staff by (102 ) teaching staff from the University of Baghdad and (72) of the university teaching staff al-Mustansiriya. In the light of the achieved results, there were a set of conclusions the most important one was the relationship and the significance impact between organizational learning and the Intellectual capital .it appeared there were no meaning full difference between the two universities about organizational learning. But there were significant differences in terms of Intellectual capital and the two variables at each university. I ended the research with series of recommendations including the necessity to employ a relationship between organizational learning and intellectual capital in the formulation of plans for public organizations in development of human resources to build its intellectual capital and maintain it
Mass transfer has been studied at rotating cylinder electrodes fabricated with spiral-wound woven-wire meshes using reduction of copper as a test reaction. The experimental data were correlated by an empirical expression between the Sherwood number and the Reynolds number, both regarding the hydraulic diameter as a characteristic length. It was found that the Sherwood number was dependent upon the Reynolds number to the power of 0.521. An enhancement factor was adopted to compare the efficiency of the new rotating cylinder electrode with previous three-dimensional rotating cylinder electrodes. The results showed that the new type has a mass-transfer enhancement factor 2.3 times higher than those obtained with smooth rotating cylinder electr

Electronic and hand searches were conducted in three electronic databases for relevant articles published up to March 2022. Retrieved articles went through a two-step screening procedure, and the risk of bias (RoB) was assessed by the Joanna Briggs Institute checklists. The incidence of GBT after OT was set as the primary outcome, while the secondary outcomes were the risk factors associated with GBT and alveolar bone loss following OT. Out of 421 papers, 5

Show MoreRapid worldwide urbanization and drastic population growth have increased the demand for new road construction, which will cause a substantial amount of natural resources such as aggregates to be consumed. The use of recycled concrete aggregate could be one of the possible ways to offset the aggregate shortage problem and reduce environmental pollution. This paper reports an experimental study of unbound granular material using recycled concrete aggregate for pavement subbase construction. Five percentages of recycled concrete aggregate obtained from two different sources with an originally designed compressive strength of 20–30 MPa as well as 31–40 MPa at three particle size levels, i.e., coarse, fine, and extra fine, were test
