This paper presents the concept prospect and operation of Green Power Zone (GPZ). The GPZ is defined as part of power grid which provides electrical energy with varying quality depends on customer requirement. Different power quality levels in the premium zone can rang from better than normal utility supply to a supply close to an ideal situation. Electrical energy to the zone is supplied through two feeders from two independent substations. The GPZ center is fully equipped with custom power devices namely dynamic voltage restorer (DVR) and distribution static compensator (DSTATCOM) or even unified power quality conditioner (UPQC). The GPZ can also contain a distributed generator (DG) to take care the power interruption situations from the utility. The incoming feeders to the zone can be designed with improved grounding insulation arresters and reclosing. The simulation results are shown the performance of GPZ by using digital computer simulation program.

Activated carbon also called activated charcoal or activated coal is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions. In this research studies environmental impacts of activated carbon production processes which produced from two types of agricultural by-products namely : coconut shells and palm-oil shells . SimaPro software is applied to evaluate the environmental impacts of both processes. The results have shown that the environmental impacts for the process using coconut shells as raw material is higher than that using palm –oil shells as raw material.

This research aimed to assess the competency for vocational education administrators under Jurisdiction the Office of Vocational Education Commission Ministry of Education by using the Needs Assessment Process to assess their 5 core competencies and 11 functional competencies. The samples were 201 vocational education administrators. The questionnaire was used for data collection. The statistics were percentage mean and standard deviation respectively. The findings were summarized as follows: 1. In overall the vocational education administrators had high levels for core and functional competencies. 2. The competencies were ordered based on its mean as follows: 2.1 Core competencies: moral and ethics good governance team work achievement motivation and expertise 2.2 Functional competencies: self confidence leadership empowering others organization awareness human resources developmentvisionself controlworks control and monitoring analytical thinking communication and strategic orientation.

Heavy metal is one of the major environmental pollutants. However the protective cellular mechanisms in response to heavy metal stress are not well-understood yet. Previously it has been found that the yeast deletion mutants lacking vacuolar H+-ATPase (V-ATPase) activity which functions in vacuolar acidification exhibited growth defects under cadmium stress conditions. In addition several genes involved in H+-ATPase have been recently found to be required for resistance to aluminum. To investigate the roles of vacuolar H+-ATPase plasma membrane H+-ATPase and mitochondrial H+-ATPase in tolerance to cadmium we examined the growth of yeast deletion mutants lacking different types of H+-ATPase in YPD media containing 80 μM of cadmium. Our results showed that a number of mutants lacking V-ATPase activity were sensitive to cadmium suggesting the important role of V-ATPase in cadmium detoxification. We next examined the growth of mutants lacking genes responsible for different vacuolar functions in order to investigate the functional activities of vacuoles involved in cadmium detoxification mechanism. We found that the mutants lacking vacuolar protein-sorting genes exhibited high sensitivity to cadmium as well suggesting the importance of protein transportation during cadmium stress.

This paper presents the development of an initial rotor position estimation of permanent magnet synchronous motors (PMSM) without a position sensors drives with embedded digital signal controller. The principle of the estimation is based on induced voltage of electromagnetic flux by injecting high-frequency voltage at standstill. The controller is embedded digital signal controller (DSC) due to the small and cheap controller. Experimental results show that changing initial frequency capable of reliable.
