  These days, using Smartphone is getting more common in the world and they are provided with powerful hardware resources and variety of communicating methods. A robust security model is applied to develop android operating systems that works on Smartphone and tablets. But it does not satisfy some users, especially whom with confidential and delicate data transmission and whom who keeps these kinds of data on their devices. At this time, users may turn to use third party applications to archive this satisfaction. In this research, a combination of Steganography and Cryptography techniques is proposed to design a third-party application for devices that run android platform to solve this issue. Also, resource limitations of different Smartphones and tablets is assessed to test whether this new technique can be handled by these devices or not as mobile devices has resource limitations if it compared to personal computers. Least Significant Bit (LSB) Steganography algorithm is used for hiding the texts and enhanced playfair algorithm as a Cryptography algorithm is used for encrypting the texts. It seems that through considering the attitudes to clean energies and their efficiency through inspiring past experiences in a combination of past and present time can not only show response to the coming problems but also it can cover some parts of economic considerations.

  The language of Iraqi education system before university study is in either Arabic or Kurdish. However, when students come to universities, especially, scientific departments, the language of instructions will become English. This often becomes a great challenge for the students to deal with. Therefore, most of the colleges set an English module as one of the required modules at the first stage. Obtaining views and perceptions from students will be helpful in improving the quality of the module effectively. This research is conducted in the University of Human Development, College of Science and Technology at the end of their first year (2015-2016). The purpose is to obtain views from students in favor of further improving the module. For this, a questionnaire which consists of twelve questions was prepared and carried out amongst hundred and sixty students. The results, show several outcomes. First, students are not so aware of the university system before they join. This is because more than half of them were shocked when they first knew that English is the language of instruction in the college. Secondly, their English has improved and they feel more confident of doing activities in English now. However, they still need more time to study English because more than a quarter of the students are not satisfied with level of their understanding. Finally, according to the class activities, the study presents that students have progressed in speaking and listening skills but still have difficulties in both writing and reading skills.
