The applications of porous media burners are of massive interest to researchers from decades, and still trending in the modern world because of their tremendous advantages, such as high thermal efficiency and low emissions. In this work, a microburner was made to achieve surface and submerged flame region for different thicknesses of preheat layers. A reaction layer of alumina foam with a predefined thickness was used, whereas the preheat layer of porcelain foam was replaced with three different thicknesses namely 5, 10, and 15 mm. By using 5 mm preheat layer, only surface flame was visible with absolutely no trace of submerged flame region, while 10 and 15 mm can undergo both surface and submerged flame region. Equivalence ratio of 0.7 was observed to give best performance with regards to surface flame, while 0.5 for submerged flame region. Only 10 mm can able to give highest thermal efficiencies reaching 90% and 38% for the surface and submerged flame region respectively. Finally, low emission rate for NOx and CO was seen for all the possible individual cases. © 2017 Elsevier Ltd

Objectives: Autologous blood pleurodesis (ABP) is used for the treatment of pneumothorax with a good efficacy. The aim of this study is to determine the efficacy and safety of ABP in the treatment of malignant pleural effusion (MPE). Methods: A prospective study was conducted at Songklanagarind Hospital, Thailand. Symptomatic MPE patients were randomized to receive pleurodesis with either autologous blood or tetracycline. In the ABP group, 100 ml of autologous venous blood was instilled via chest tube followed by 50 ml of sterile normal saline (NSS). In the tetracycline group, 20 ml of 1% lidocaine diluted in 30 ml NSS was instilled followed by 1 g of tetracycline diluted in 100 ml of NSS. The chest tube was clamped for 2 hours, then reconnected to suction and removed. Pleurodesis effectiveness was evaluated according to Paladine's criteria and adverse events were recorded. Results: A total of 48 symptomatic MPE patients were recruited. Of these, 24 cases were randomized to receive ABP and 24 cases received tetracycline. There was no difference between the two groups in baseline characteristics. The overall success rate of pleurodesis was the same in both the autologous blood group and the tetracycline group (83.4% versus 87.5%, p = 0.36). In the ABP group, the pain score and fever were significantly lower (8.3% versus 29.1%, p = 0.003) and there was a small percentage of cases that needed analgesia (4.2% versus 75%, p ≤ 0.001); no serious events occurred. Conclusions:: ABP was as effective as tetracycline in the treatment of MPE. ABP produced less pain and fever, and could shorten the hospital stay. © The Author(s), 2015.

The friction coefficient of the sulphurprevulcanized natural rubber (SPNR) film could be effectively reduced by deposition of poly(methyl methacrylate) (PMMA) particles. The nanoscale surface roughness of rubber, determined by atomic force microscope, was directly proportional to the particle size of PMMA particle at 12% surface coverage (Cs). The %Cs and surface roughness of the modified SPNR increased, while the friction coefficient decreased, with increasing PMMA latex concentration and immersion time. By using a mixture of latexes having both large and small sizes, the increase in the amount of small particles resulted in the better distribution of large particles deposited on the rubber surface. © 2009 Wiley Periodicals, Inc.

The purpose of this study is to provide a scale development process, in order to preliminarily address the reliability and validity of CEO transformational leadership, some key organizational factors, and product innovation performance constructs. Data for this study were collected from 264 manufacturing firms in Thailand. The measurement scales were pre-assessed using the Q-sort method, and exploratory factor analysis (EFA) was also conducted to assess the construct reliability and validity. This research established a theoretical framework of CEO transformational leadership, organizational factors including innovation strategy, organizational learning, innovation culture, new product development process, and product innovation performance. Q-sort technique and EFA can help improve the content validity and the construct validity of CEO transformational leadership, some key organizational factors, and product innovation performance. This study provided the initial developmental steps toward the building of a theoretical framework and scale measurement to allow better understanding of the constructs based on the context of firms in Thailand. This will allow researchers to bring new insights when exploring these constructs under differing operational conditions. The findings address additional steps required towards improved methodological aspects in terms of how to pre-validate and develop a measurement scale in various constructs within alternative domains.

In order to enhance the number of completions, educational institutes establish and implement strategies to improve students' satisfaction and academic development. Technological supports are a strategy that many universities provide to service and assist staff and students. In this study, a prediction model called Electronic Grade (e-Grade) is used to model the likelihood of a student's Grade and achievement for particular subjects. This model aims to assist lecturers to supervise students, and to pay extra attention for students who are likely to get marginal results that could lead to withdrawal prior to completion of that subject. The e-Grade model comprises two sub-models that are Likelihood of Grade Before midterm examination, and Likelihood of Grade After midterm examination. In the experiment, two datasets are used. The results will provide supports to counsel the students on their possible performance and classroom achievement. The usefulness of the proposed e-Grade model for the monitoring of students' progress is verified against benchmark data. The results are interpretation of the performance of the new model of research based on linear regression and clustering techniques. The experiment results found that the proposed model enhances the accuracy of linear regression techniques in comparison to the benchmark model. © 2013 IEEE.

This systematic review paper integrates and analyzes previous empirical results between 2002-2012 to characterize the theories and variables that examine the leadership-innovation relationship. Even though there were many studies examining the effects of leadership on various types of innovation, the empirical results showing the leadership-product innovation relationship were scarce. Among a variety of styles or characteristics of leadership, transformational leadership was used most as explanatory variable to predict innovation. However, there was no single study revealing the positive effect of transformational leadership on product innovation. This article provides the pathway for researchers to further investigate the leadership-product innovation relationship. © 2012 IEEE.

In order to support the academic management processes, many universities in Thailand have developed innovative information systems and services with an aim to enhance efficiency and student relationship. Some of these initiatives are in the form of a Student Recommendation System (SRM). However, the success or appropriateness of such system depends on the expertise and knowledge of the counselor. This paper describes the development of a proposed Intelligent Recommendation System (IRS) framework and experimental results. The proposed system is based on an investigation of the possible correlations between the students' historic records and final results. Neural Network techniques have been used with an aim to find the structures and relationships within the data, and the final Grade Point Averages of freshmen in a number of courses are the subjects of interest. This information will help the counselors in recommending the appropriate courses for students thereby increasing their chances of success.

The title aza-stilbene derivative, C14H13NO2 {systematic name: (E)-2-[(4-meth-oxy-benzyl-idene)amino]-phenol}, is a product of the condensation reaction between 4-meth-oxy-benzaldehyde and 2-amino-phenol. The mol-ecule adopts an E conformation with respect to the azomethine C=N bond and is almost planar, the dihedral angle between the two substituted benzene rings being 3.29(4). The meth-oxy group is coplanar with the benzene ring to which it is attached, the Cmeth-yl-O-C-C torsion angle being -1.14(12). There is an intra-molecular O-HN hydrogen bond generating an S(5) ring motif. In the crystal, mol-ecules are linked via C-HO hydrogen bonds, forming zigzag chains along [10-1]. The chains are linked via C-H inter-actions, forming a three-dimensional structure.
