Design of Wireless Automatic Microwave Antenna Alignment System

Microwave link aligning is an important operation in communication systems. Misalignment in line of sight link due to rain, wind etc considered the basic problem that faced the microwave system. This problem caused a direct terminating of the microwave link. Automatic antenna alignment will guarantee best communication at the link’s ends without any risks of human interface. This paper presented a low cost design of an automatic antenna alignment system based on arduino and using Xbee wireless technology. The design in the paper is automatically adjusting the horizontal and vertical angles in the transmitter and receiver sides of the microwave link. The controller compared the measured values of these two angles with a reference values. The correction of the error in the angles is done by moving the antenna towards the correct position. The design was tested in different angles positions and the results were reported in the paper. The simulation results ensure that the system works successfully

The Role of the Universities in Counterterrorism and Electronic Extremism from the Viewpoint of the Faculty Members at Al Balqa Applied University and Naif Arab University for Security Sciences

The purpose of the study is to investigate the role of the universities in counterterrorism and electronic extremism from the view point of faculty members at Al Balqa Applied University and Naif Arab University for Security Sciences; it aims also to investigate the effect of faculty members' gender, academic qualification, and experience on their viewpoint. The sample of the study was selected purposefully. It consisted of (94) faculty members, (71) male and (23) female faculty members at Al Balqa Applied University and Naif Arab University for Security Sciences. This sample was used to investigate the role of the universities in counterterrorism and electronic extremism and a questionnaire was distributed among them.The findings of the study indicated that there are no statistically significant differences at (α= 0.05) in faculty members' views about the role of the universities in counterterrorism and electronic extremism due to Gender variable. Results also showed that there are statistically significant differences at (α= 0.05) in faculty members' opinion due to qualification variable in favor of PhD Degree, there are statistically significant differences at (α= 0.05) due to experience variable. To find out Multiple Comparisons differences post hoc test using Scheffe Method was conducted, results showed that there are statistically significant differences at (α= 0.05) between Less than 5 years and 10 years or above in favor of 10 years or above. Keywords: Counterterrorism, Electronic Extremism

The Level of Ethical Sensitivity among Jordanian University Students According to their Educational Level & Specialization

This study aimed to investigate the level of ethical sensitivity among Princess Alia University College Students in Jordan and how this is influenced by their educational level and specialization. To achieve the objects of the study, the ethical sensitivity scale questionnaire (ESSQ) was used, as developed by Narvaez (2001). This was used to measure the moral sensitivity of adults and adolescents. It consists of (28) items in seven dimensions, which are the ability to read emotions, to represent the views of others, interest in communication with others, the activation of personal relations, taking into account differences and controlling social prejudice, working to generate interpretations and alternatives, and identifying the consequences of an event and the available options. The sample of the study consisted of (126) randomly selected undergraduate and graduate students. The results of the study showed that the level of ethical sensitivity among Princess Alia University College Students was low, and there were statistically significant differences in the level of ethical sensitivity due to specialization, in favor of humanities students, as well as statistically significant differences in the level of ethical sensitivity due to the educational level, in favor of master’s students

Length versus radius relationship for ZnO nanowires grown via vapour phase transport

We model the growth of ZnO nanowires via vapour phase transport and examine the relationship predicted between the nanowire length and radius. The model predicts that the lengths of the nanowires increase with decreasing nanowire radii. This prediction is in very good agreement with experimental data from a variety of nanowire samples, including samples showing a broad range of nanowire radii and samples grown using a lithographic technique to constrain the nanowire radius. The close agreement of the model and the experimental data strongly support supporting the inclusion of a surface diffusion term in the model for the incorporation of species into a growing nanowire

Teachers’ Perspectives on Social Values and Their Influence on Sustainable Development in Ajloun Governorate

This study examines the level of social values among teachers and its correlation with their understanding of sustainable development requirements. The study’s sample consisted of 220 teachers randomly selected from Ajloun schools. The study's findings indicate that social values are highly regarded across various domains, except for work values, which received an average ranking. Moreover, the results reveal a statistically significant gender-based difference in the level of social values (α = 0.05), favoring females, as well as variations based on experience, favoring the “9 years or more” category. Furthermore, the study highlights a strong awareness of the interconnected requirements for sustainable development, particularly in social, environmental, and economic dimensions. The findings also demonstrate a statistically significant positive correlation (α = 0.01) between participants’ overall evaluation of social values and their comprehensive assessment of sustainable development principles. The study proposes the integration of societal ideals and sustainable development criteria into student curricula and teacher training programs. This integration aims to enhance the understanding and application of sustainable development concepts among teachers
