Today wireless sensor networks are developed and comprised of a small fully autonomous processing communication and sensing devices. It has been restricted power supply low computing power. WSNs work in vast area unreachable or crucial area send and receive raw data from each sensor node. It has the ability to cooperatively collect data and retransmit in order to process or alert. This paper used ns-2 simulation propose a power efficient wireless sensor network ant colony system that can adapt it’s function to reduce average energy consumption per node and work in area for a longer time.

This paper proposes a study of an Ozone generator. The generator under the study is designed using the electrode with uniform field. The electrode is constructed in the plane shape with positive potential. The transformer oil is used as insulating materials to prevent discharges around the electrode discharges in the air void depends on the size the types of dielectrics and level of applied voltage. Between the electrode and the air void there is acyclic dielectric. The stainless electrode with water is used as a ground potential. The breakdown depends on the electric field intensity. It is found that there is sufficient amount of ozone due to the ionization Development and design ozone generator this research electric field intensity on the water type and this can be used as a principle to construct a new type of ozone generator.

Presently the application of computer technologies for pedagogical purposes have been spectacularly realised across a variety of disciplines. In terms of foreign language teaching and learning; researchers educators and teachers are aware of the increasingly prominent role of computer-assisted language learning (CALL). The article therefore manifests interesting research findings and opinions concerning computer usage in the sphere of language education. In the first section the emphasis is put on history and new trends of CALL usage. Then computer and language learning and teaching are discussed through contrastive points of view based on a literature study of researchers and educators involved in language pedagogy. Instead of reviewing extensive advantages of CALL for both teachers and learners limitations are also discussed particularly for the teachers to gain a critical insight as to how computer technologies may affect language learners and classrooms. Finally suggestions and recommendations for integrating CALL into language classroom are provided in order to maximise the exploitation of computer technologies to its full potential.

Hydraulic machines were used in both medium and large scale From industries studying problems of hydraulic systems around 70-80 percentage of the machine expiration was due to the deterioration of hydraulic oil from contamination so the best way to maintain the hydraulic machine was to take care of hydraulic oil to have the purity level and other properties suitable for the components in those machines. This article described the duty of hydraulic oil types of contamination sources of contamination the standard for measuring the purity level of oil equipments used to measure and analyze the contamination in hydraulic oil recommended purity levels the effects from the contamination in hydraulic oil to machine and methods to protect and to eliminate the contamination in hydraulic oil. All of these were useful as the guidelines to maintain the hydraulic machines to work in high efficiency and more long life time.

Rajamangala University of Technology Phra Nakhon has gained support from the Commission on Higher Education to set up a business incubators unit called Rajamangala University of Technology Phra Nakhon - University Business Incubators or RMUTP-UBI. The agency has a principal missihon in creating new potential entrepreneurs by utilizing results of research works inventions innovations and technology of the university. The agency๛s main aim is to get income for oneself for the university and for the country as a whole; as well as to provide information service and consultation to users both inside and outside the university. In 2007 the RMUTP-UBI had incubated 10 entrepreneurs. Among these 2 were start-up companies 3 were incubatees and 5 were pre-incubatees. It also conducted public relations visiting tours trainings setting up activity groups of students and entrepreneurs and providing academic services to meet the goal of the project.
