The Subject

The excretion system are completely abstractive and complex, so it is desirable a tool that can visualize the excretion process and enable students to understand the modules well. The using of picture storybook is potential to increase the interest and activities of students. The response is a measurable reaction produced by somebody in analyzing an object that can generate an attitude. So, the purpose of this study is to investigate students’ responses to the picture storybook as a part of the teaching material which can facilitate students' thinking. This study involved the seven steps: the introduction, planning, and development of the initial product, initial field trial, revision on the main product, field trial, and revision on the operational product. The field trial was conducted to determine students’ responses to the dimension of cognitive, affective, and conative aspects through exploring three secondary schools around Pontianak, Indonesia.  Subjects in this study were students in grade 8 who had been educated with an excretion system with a total number of three students in each school for the initial field trials; while there were 12 students from each school for the main field trials. Instruments used in this study were a validation paper and a student response form. The results of the initial field trial showed the cognitive aspects (84.57%); the affective aspects (89.38%); and the conative aspects (89.46%). The implication of this research was about the possibility to use a picture storybook for increasing students' interests in science learning that we examined by the subject categories

Test Result

Field test of particle impact drilling (PID) technology was firstly carried out in deep well and hard formation in Sichuan province china on Oct. 2013. The test formation was named Xu Jiahe, which was very difficult to penetration. Field test result shows that the ROP (rate of penetration) was nearly doubled by this technology. It indicates that there is a profound application prospect of particle impact drilling, especially for hard rock formation. In this paper, the equipment and working principle was analyzed. The experiment and simulation results showed that the rock breaking efficiency was highly increased by this technology. The details of this field test were presented too in this paper that proved the sound effect of PID.

This paper represents a preliminary study of the botany, natural history and taxane chemistry of the Mexican yew, Taxus globosa Schltdl. Taxonomic history, morphological comparison to other North American species and ecological habitat are discussed. Chemical study involved leaf and twig material from forty-nine plants from three localities in Mexico. Levels of taxol, cephalomannine and baccatin III were determined by HPLC analysis. Intrapopulational variation was found to be very high while mean taxane levels for each of the three populations were very similar. The average percentage of taxol in leaves of T. globosa is higher than in all other species of Taxus (0.0121% dry wt.).
