Abstract

Givotia rottleriformis Griff. (Vern: Tel-Tella Poniki), the White catamaran deciduous tree, is traditionally used in the toy industry. Due to regular cutting and over exploitation, this species has become endangered. Propagation of this species is mainly through seed and the natural regeneration of the species through seed is very poor. In order to enhance the seed germination percentage, the seeds were treated with different concentrations and durations of GA₃. The results of germination evaluation after 36 hrs of sowing revealed the beneficial effects of GA₃. (3%) over the rest with 90 per cent germination against 5 per cent in control. It was observed that the GA₃. treated seeds showed the enhancement in germination and breakage of seed dormancy in the species. Thus the present methodology can be used for in-situ conservation of the species.

Abstract

Distributed generation (DG) generally refer to small scale electric power generators produce electricity that is bound to an electric distribution system. Distributed generation systems such as photovoltaic (PV) or wind energy systems are parts of the future smart grids. By applying intelligent techniques these future grids change as smarter grids. During the past few years electrical energy consumption to the investment is increased when compared to cost on transmission and distribution resulting in compromised reliability and high energy costs. So there is need to change from conventional grid to smart grid. Micro grids consist of small power sources called distributed generation system. Many distributed generation systems such as photovoltaic systems are grid interfaced through power electronic voltage source inverters.

In this paper a boost inverter technique is explained and distributed generation sources such as PV and fuel cell are connected in series with the help of PQ controller technique the above system is evaluated.

Keywords

Abstract

In the current era of education, quality of the content delivery is considered as important as the course content, to attain the objectives of the course. Quality content delivery method influences the student and emphasis on active learning strategies. This paper describes collaboration of learning practices with specialized topics in stream line approach mindmapping using jigsaw method. The jigsaw method is an effective way to increase student engagement through group work that facilitates peer-to-peer learning. Teams of students are assigned to investigate different aspects of the topics or issue. Assign the different problems/topics to each team. Once each team members thoroughly understands his/her team's aspect of the problem in content Based Learning using Mind- Mapping, then after, new groups are formed, with at least one representative from each original team. Each individual then explains his/her team's aspect of the problem to the new group. In this way, every student learns every aspect of the problem/topic. Each group expected to explain their aspects to other team members in Expert Team, then uses the combined information to evaluate a summary issue. In our study we have divided the five members as a team and batches and assigned the different problems of different topics to all the teams. Analyze the student's performance batch wise, formative assessment and summative assessment has performed. This approach can index that in one session all students are learned in cooperative learning with Mind-Mapping and each student in each group becomes an 'expert' on a smaller part of problems /topics.
