Thammasat University , or in brief TU , is Thailand's second oldest institute of higher education. Officially established to be the national university of Thailand on 27 June 1934, the university was originally named by founder Pridi Banomyong, The University of Moral and Political science , reflecting the political fervor of Thailand. It started as an open university, with 7,094 students enrolled in its first academic year studying law and politics. The guiding philosophy of the university was "to teach students to love and cherish democracy". In 1952, the university's name was shortened to its present one by the military junta of Field Marshal Plaek Phibunsongkhram who also became the first rector of the university. Nevertheless, Thammasat University has always been involved in Thai national politics, counting most Thai political leaders among its graduates. Its original campus at Tha Phra Chan was the site of the 14 October 1973 uprising and the 6 October 1976 Massacre.In 1960, the university ended its free-entry policy and became the first university in Thailand that requires passing national entrance examinations for admission. Thammasat today offers more than 240 academic programs in 23 different faculties and colleges located on four campuses. Over the nearly 80 years since its founding, Thammasat University has evolved from an open university for law and politics to a prestigious international university offering all levels of academic degrees in many fields and disciplines. It has graduated more than 300,000 undergraduate and graduate students who have greatly contributed to the development and progress of Thai society and the nation. The university’s alumni have included most of all Prime Ministers, leading politicians and government figures, Bank of Thailand governors, Supreme Court presidents, judicial officers, and most of the city’s governors. The university's Bangkok Campus is in Phra Nakhon, Bangkok in close proximity to many tourist destinations. The Rangsit campus, where most undergraduate programmes are now held, is in Khlong Luang, Pathum Thani. Thammasat has smaller regional campuses in Lampang, Pattaya, Narathiwat, and Udon Thani. It is ranked No.447 in the world by QS. Wikipedia.

Continued progress in cell-phone devices has made them powerful mobile computers, equipped with sophisticated, permanent physical sensors embedded as the default configuration. By contrast, the incorporation of permanent biosensors in cell-phone units has been prevented by the multivocal nature of the stimuli and the reactions involved in biosensing and chemical sensing. Biosensing with cell phones entails the complementation of biosensing devices with the physical sensors and communication and processing capabilities of modern cell phones. Biosensing, chemical-sensing, environmental-sensing, and diagnostic capabilities would thus be supported and run on the residual capacity of existing cell-phone infrastructure. The technologies necessary to materialize such a scenario have emerged in different fields and applications. This article addresses the progress on cell-phone biosensing, the specific compromises, and the blend of technologies required to craft biosensing on cell phones. © 2014 Elsevier Ltd.

BANGKOK, Feb. 28, 2017 /PRNewswire/ -- Thammasat University (TU), Thailand's second-oldest university, has launched an initiative to install solar panels on its rooftops for intra-campus electricity generating with the goal of reaching overall production of 15 megawatts by the end of 2017, the biggest among all universities in Asia and the fourth-largest in the world. Professor Dr. Somkit Lertpaithoon, Thammasat University rector, said the move was part of TU's "Sustainable University" project. The solar rooftops are set to be installed at the university's Rangsit Campus in two phases. The first phase will generate a total of six megawatts of power and the second phase will bring the total to nine megawatts by the end of 2017. Currently, the top three universities in the world with the highest capacity of electricity generated from solar cells are Colby College at 30 megawatts, Arizona State University at 24 megawatts and the University of California at 16 megawatts. All three are located in the US. If the initiative is completed in 2017, the rector said that TU will become the number one university in Asia in terms of rooftop power generating, replacing Nanyang Technological Univeristy in Singapore, which generates five megawatts of electricity from its current rooftop project, the world's fourth-most, after the three US-based universities. TU deputy rector Parinya Thewanarumitkul said that fossil consumption is the major factor behind global warming and climate change. Thailand generates nearly 70% of its electricity from fossil fuel. The initiative will help support TU to generate around 30-40% of its own electricity.

Head and neck squamous cell carcinoma (HNSCC) is a complex tissue that contains tumor cells and the surrounding stroma, which is populated by different types of mesenchymal cells and the extracellular matrix (ECM). Collectively, they are referred to as the tumor microenvironment (TME). Recent studies have shown that TME has a more profound influence on the growth and metastasis of HNSCC than was previously appreciated. Because carcinoma- associated fibroblasts (CAFs) are frequently observed in the stroma of the tumor, this review focuses on the potential role of tumor-CAFs interactions in progression of HNSCC. Tumor-CAFs crosstalk enhances the production of growth factors, cytokines, chemokines, matrix metalloproteinases (MMPs), and inflammatory mediators, which eventually facilitates tumor growth. In fact, factors and cells that do not support tumor growth are usually down regulated or mitigated in TME. Therefore TME may determine the fate of the tumors at the site of invasion and metastasis. For tumor cells that survive at these sites, stromal activation may serve to establish a supportive tumor stroma, fostering the outgrowth of the metastatic cells. The concept of tumor-stromal interactions and microenvironmental niche has profound consequences in tumor growth and metastasis and therefore, it's understanding will open up new strategies for the diagnosis, prognosis and therapy of HNSCC. © Ivyspring International Publisher.

Portal hypertension (PH) plays an important role in the natural history of cirrhosis, and is associated with several clinical consequences. The introduction of transjugular intrahepatic portosystemic shunts (TIPS) in the 1980s has been regarded as a major technical advance in the management of the PH-related complications. At present, polytetrafluoroethylene-covered stents are the preferred option over traditional bare metal stents. TIPS is currently indicated as a salvage therapy in patients with bleeding esophageal varices who fail standard treatment. Recently, applying TIPS early (within 72 h after admission) has been shown to be an effective and life-saving treatment in those with high-risk variceal bleeding. In addition, TIPS is recommended as the second-line treatment for secondary prophylaxis. For bleeding gastric varices, applying TIPS was able to achieve hemostasis in more than 90% of patients. More trials are needed to clarify the efficacy of TIPS compared with other treatment modalities, including cyanoacrylate injection and balloon retrograde transvenous obliteration of gastric varices. TIPS should also be considered in bleeding ectopic varices and refractory portal hypertensive gastropathy. In patients with refractory ascites, there is growing evidence that TIPS not only results in better control of ascites, but also improves long-term survival in appropriately selected candidates. In addition, TIPS is a promising treatment for refractory hepatic hydrothorax. However, the role of TIPS in the treatment of hepatorenal and hepatopulmonary syndrome is not well defined. The advantage of TIPS is offset by a risk of developing hepatic encephalopathy, the most relevant postprocedural complication. Emerging data are addressing the determination the optimal time and patient selection for TIPS placement aiming at improving long-term treatment outcome. This review is aimed at summarizing the published data regarding the application of TIPS in the management of complications related to PH. © 2014 Baishideng Publishing Group Inc.

This paper describes an orientation-independent method for detecting activities of daily living based on reference coordinate transformation. With the proposed method, a classification model can be trained using data acquired during a specific sensor orientation and applied to other input signals regardless of the orientation of the device. The technique is validated using activity recognition experiments with four different orientations of a single tri-axial accelerometer placed on the waist of 13 subjects performing a sub-class of activities of daily living. A high subject- independent accuracy of 90.42% has been achieved, reflecting a significant improvement of 11.74% and 16.58%, compared with classification without input transformation and classification with orientation-specific models, respectively. © 2010 IEEE.

The paper presents a survey of five-axis computer numerical controlled (CNC) machining optimization methods employing adaptable geometric patterns. First, the survey introduces evolution of CNC interpolators from the simplest Taylor series-based routines to sophisticated procedures based on constraint minimization from dynamic systems control theory. Furthermore, a variety of methods based on spline interpolation, NURBS interpolation and Farouki's Pythagorean-hodograph curves is presented and analyzed. Next, the survey deals with techniques to optimize the positions and orientations of the tool in a particular neighborhood of the part surface. The most important application of these techniques is cutting by a flat-end or a fillet mill while avoiding local overcuts or undercuts due to the curvature interference and rear gouging. This section is supplemented by detection of global interference using visibility cone schemes and their recent modifications and improvements. Solutions offered by solid modeling are presented as well. Finally, adaptable geometric patterns employed for tool path generation are considered and analyzed. The adaptation is performed using certain criteria of the tool path quality, such as kinematics error, scallops, possible undercuts or overcuts, and the continuity of the path. Also covered are complex pocket milling employing geometric patterns capable of following the boundary, such as the offset methods, regional milling, the potential path methods, and clustering. The chapter also presents tool path optimization based on the adaptable curvilinear grids connecting the cutter location points. Finally, navigation approaches and the shortest-path schemes are considered, along with the adaptive spacefilling curve algorithms and their combinations with grid generation.© Springer-Verlag London Limited 2009.

Energy and energy security have become important to countries aiming to go on the path of sustainable development. In this regard this paper analyses the improvement of energy security which occurs as a result of energy efficiency (EE) improvements in the power sector. In this paper energy security is measured along three main themes which are oil security, gas security and sustainability. The energy systems of the selected countries, namely Sri Lanka, Thailand and Vietnam are modeled using an integer programming based optimization model called Model for Energy Supply Strategy Alternatives and their General Environmental Impacts - MESSAGE. Each country is modeled with two scenarios namely the reference scenario which maintains the status quo at the start year and the EE scenario which models EE options in the demand side as supply side alternatives. The time horizon is 2007-2030, where 2007 is the base year and 2030 is the end year. The results are presented for oil security, gas security, sustainability, and also for co-benefits such as mitigation of CO2 emissions, reduction in conventional primary energy use and reduction of local air pollutants such as SO2 and NOx. Results show that energy efficiency in Sri Lanka significantly increases the energy security whilst also accruing co-benefits of CO2 mitigation, mitigation of local air pollution and reducing the conventional primary energy use. In the case of Thailand and Vietnam, energy security is enhanced in the earlier years (2007-2015), but in the longer term of modeling horizon (2020-2030) energy security of both the reference and EE scenarios converge indicating that in terms of long term energy security implementing energy efficiency measures alone would not enhance energy security. © 2012 Elsevier Ltd.

This paper discusses the strengthening of opening in R/C beams by FRP rods. A total number of thirteen beams with circular and square opening have been tested. The opening is shown to significantly reduce the shear capacity of beam. Two patterns of strengthening by FRP rod are investigated: one is to place FRP rods enclosing the opening and the other is to place FRP rods diagonally throughout the entire depth of the beam. It is found that simply placing FRP rods around the opening is not fully effective because a diagonal crack can propagate through the beam with the crack path diverted to avoid intersecting with the FRP rod. When FRP rods are placed throughout the entire beam's depth, a significant improvement in loading capacity and ductility is achieved, similar to strengthening by pre-fabricated internal steel bars. The flexural failure mode is restored. A nonlinear finite element analysis, based on smeared crack approach, is conducted for numerical verification and examining the effect of length, position and inclination of FRP rods. The plot of analytical principal compressive stress illustrates two strut mechanisms associated with FRP rod. The inclined rods are found to be more effective than vertical ones. © 2009 Elsevier Ltd.
