Against a backdrop of increasing internationalization in higher education, students and teachers frequently move between learning-to-write and writing-to-learn. For example, in English as a foreign/second language (EFL/ESL) classrooms, learning-to-write would be a priority, whereas in English as a medium of instruction (EMI) classrooms, writing-to-learn may be a more appropriate goal. However, little is known about how teachers who move between such classrooms adjust their writing pedagogy as they do so. Accordingly, we bring together the views, beliefs, and experiences of three Thai university lecturers who teach across EFL, CLIL, and EMI platforms. Collectively, they serve as researchers/participants in the co-construction of joint autoethnographies on teaching English writing at Thai universities. Their emergent themes give valuable insights into how they navigate the complexities of moving between language and content concerns, expectations and realities, and idealism and pragmatism. Results also show how there is no one-size-fits-all approach for these researchers/ participants, and that both bottom-up and top-down constraints shape their actions and beliefs as writing teachers. Overall, by drawing on their combined experiences, we hope to raise awareness of the challenges placed upon English language teachers when teaching writing and provide useful guidance for those working in similar contexts.

The purposes of this research were 1) to study satisfaction of website visitors about mushrooms products website in community enterprise at Prachaupkirikhan province in 3 aspects; design, contents, and application and 2) to add supplemental opinions and suggestions. Research samples were 387 internet users, derived through simple random sampling technique. The instruments used for gathering the data were the rating-scale and open-ended questionnaire. The statistics used for analyzing the data were frequency, percentage, mean, standard deviation, and content analysis. Research findings were as follows: 1) satisfaction of website visitors about mushrooms products website in community enterprise at Prachaup kirikhan province was a high level, when considered in each aspect it was found that all aspects were at a high level, and 2) the supplemental suggestions gathered from this study were; the mushrooms products website in community enterprise at Prachaup kirikhan province is interesting, especially in the video of demonstrating about how to use mushrooms products.

During the last decade, there have been two RANS-based transition models used in commercial CFD software: θ γ Re − model and L k model. The present work is aimed to combine the merit parts of both transition models. Apart from the base turbu-lence model, the transition model proposed here is composed of the original L k -equation and the new γ algebraic model. Only the production and destruc-tion terms of the turbulent kinetic energy equation are modified to account for the transitional effect on the mean flow. Compared to the original L k model, the number of constants and functions in this alge-braic model is reduced from 27 to 16, and 9 to 8 re-spectively. Its performance is tested using the ex-perimental data of T3B, T3A, T3AM and TSK, and its results are compared with those of the θ γ Re − and L k models in terms of the distributions of the skin friction coefficient along the flat plate. Besides its less computational time, the present model is more accurate than the original L k model in cases of T3A, T3AM and TSK.

The design of IP network that support traffic engineering for both unicast and multicast traffic is a very difficult problem. This paper proposes an IP network design algorithm called M-MENTOR that concern routing of both types of traffic. However, since multicast traffic model could be employed in many situations and could be managed by various kinds of multicast routing protocols, this paper consider only the design process of the IP networks with following features: (1) network of within the same Autonomous System (AS), (2) routing protocol support multiple weight on each link, (3) the multicast traffic from different sources share the same multicast tree.

1. Abstract In this paper, Equal Gain Combining (EGC) technique is considered because it provides performance comparable to the optimal Maximal ratio combining (MRC) technique but with greater simplicity. Although, performance evaluation of EGC diversity is a much more difficult task in comparison with other classical techniques but it has been presented several times in literature. However, the problem concerning multiple antennas on limited space has never been presented. This is because the correlation between multiple antennas can be neglected if the antenna spacing is large enough. In practice, the dimension of user terminal is fixed with the trend of small in size. Therefore, it is impossible to avoid the effect of antenna correlation due to limited space. In this paper, the performance investigation of EGC diversity technique is presented by considering the problem of multiple antennas on limited space. The simulation results reveal the significant differences observed if neglecting the antenna correlation.

The design of IP networks to support traffic engineering for both unicast and multicast traffic is a very difficult problem. This paper proposes a heuristic design algorithm called M-MENTOR that concern routing of both types of traffic. However, since multicast traffic model could be employed in many situations and could be managed by various kinds of multicast routing protocols, this paper consider only the design process of the IP networks with following features: (1) network of within the same Autonomous System (AS), (2) routing protocol support multiple weight on each link, (3) the multicast traffic from different sources share the same multicast tree. The efficiency of M-MENTOR is evaluated for various traffic demands and networks of 10, 30 and 50 node and compared with MENTOR-II. The experimental results show that, in almost all cases, M-MENTOR give better performance in term of installation cost.

An investigation was carried out into the fate and behaviour of metals and heavy metals contained in septage when applied to constructed wetlands for dewatering. Total metal contents in raw septage were determined, as well as their accumulation in the dewatered septage layer as the organic matter gradually decomposes. Metal availability was assessed by means of analysis of plant uptake by Typha angustifolia, as well as by single and sequential extraction techniques. Metal mobility was also assessed in terms of leachability. It was found that most metal concentrations in septage are very low, except Zn. Upon organic matter decomposition, zinc accumulation will possibly exceed safe levels for reuse as fertilizer or soil amendment, as shown by the heating experiment. In the field, no significant accumulation is yet observed due to the limited degree of decomposition. Fifty to ninety percent of zinc was extracted by NH 4 OA-EDTA solution, which means that Zn is readily available for plant uptake and for leaching. Both phenomena were observed. The high uptake of Cu and Zn caused a reduced uptake of essential elements such as Mn and Fe, which could possibly lead to deficiency symptoms.

This paper presents an algorithm for Thai-English cross-language transliterated word retrieval. The algorithm enables retrieval of documents containing either the Eng-lish keywords or the corresponding English-to-Thai transliterated words. This is done by retrieving docu-ments based on phonetic codes of keywords rather than the keywords themselves. The phonetic coding is based on the Soundex coding of Odell and Russell where the encoding table is slightly modified to incorporate Thai characters and the code is extended to unlimited length. Experimental results showed that a high recall and precision of more than 80% can be achieved especially when the phonetic codes are longer than four.

Sludge or septage treatment technologies as are used in larger treatment systems in industrialized countries (e.g. mixed anaerobic digesters; chemically aided, mechanical dewatering/drying systems) proved to usually not be sustainable in developing countries. Cost of investment and operation of such systems are typically beyond economic and financial affordability. The constructed wetland system, a sand-gravel filter cultivated with emergent plants such as cattails, has already proven to be an efficient and low-cost technology for sludge and wastewater treatment. To investigate and evaluate the potential of this technology also for septage treatment, the vertical-flow pilot plants were constructed at AIT and planting with narrow-leave cattails (Typha augustifolia). Design considerations such as removal mechanisms and treatment components of the AIT pilot-plants were described in the context.
