Capillary pressure curve is used to account for the mass transport limitation in the porous gas diffusion layer (GDL) in modeling two-phase phenomena in conventional distributors. Various assumptions and approximations on capillary pressure curve have been made to develop models. To date the capillary pressure curve in gas diffusion medium in PEM fuel cell does not seem to have been obtained. In this study, volume displacement technique and neutron imaging technique that can obtain capillary pressure curve in gas diffusion material is described. An experimental data of capillary pressure curve of porous material used in PEM fuel cell will help two-phase models of PEM fuel cell to be more accurate in their predictions of fuel cell behaviors.

This paper discusses teaching approach and media in English as a foreign language (EFL) classroom. It brings to lights vocabulary teaching, bilingual approach and using flashcards in the teaching of vocabulary to young learners. As teaching vocabulary can take place from very early stage to a high level of learning, its introduction needs to be managed in such a way using an appropriate approach along with utilizing particular media, such as flashcards, that the learners can enjoy the teaching process. This is based on the consideration that not all teaching media fit in the context of vocabulary teaching through bilingual approach. For this reason, it is important that teachers of English whose concern is how young learners learn vocabulary adopt appropriate teaching media on their behalf. Once the learners feel secured and confortable with the media used, it is guaranteed that they can learn as many words as possible and, thus, the desired outcome of the learning can be projected to occur. This article emphasizes the issue of bringing together bilingual approach and flahcards together in the teaching of vocabulary to young learners.

This research aims to determine if using POSSE Strategy affects reading comprehension of students majoring in English education of Tadulako University. This is a pre-experimental study using the one group pretest and posttest design. The population was 319 students in academic year 2018/2019. The samples were 35 students selected employing purposive sampling technique. Paper-and-pencil method was used when collecting the data with a test as the instrument. The test was administered twice namely pretest and posttest. The data were analyzed statistically using .05 level of significance and 34 degree of freedom. The result showed that after receiving intervention through POSSE Strategy, students scores got improved. In other words, using POSSE Strategy is effective in improving the sampled-students’ reading comprehension on any kinds of English text.
