title: Treatment of synthetic cutting-oily wastewater by induced air flotation combined with coagulation process and reactive oil concept

description: To study the treatment efficiency of cutting oily-wastewater by using Induced Air Flotation (IAF) process combined with coagulation process called as Modified Induced Air Flotation (MIAF) and also reactive oily bubble concept. The experiment was conducted in 2 flotation columns; small column with 4.2 cm diameter and large column with 10 cm diameter. The optimal operating condition (gas flow rate, chemical dosage, bubble hydrodynamic and residence time distribution, RTD) were investigated whereby the batch and continuous processes. The results showed that cutting oil-droplet (average size approximately 1.3 µm) cannot be separated by decantation and also caused some limitation to IAF and reactive oily bubble coated with kerosene flotation processes. Concerning to the study of coagulation in jar test, the optimal condition was at an initial pH 7 and 150 mg/L of alum: highest removal efficiency was 91.23%. Note that this condition was then applied further in MIAF process. The treatment efficiencies obtained with small and large columns in batch MIAF process were 94.69% and 82.97%, respectively. The optimal conditions were 150 mg/L of alum dosage and 1.0 L/min of gas flow rate for the small column and 225 mg/L of alum and 2.0 L/min of gas flow rate for large column. Moreover, the treatment of cutting oily-wastewater was independent on a/G ratio related with bubble hydrodynamics and mixing parameters, and thus causes some limitation on oil droplet-bubbles agglomeration. In this work, the chemical destabilization was proven as the important treatment mechanism. Moreover, in continuous process, the treatment efficiencies obtained with small column (80%) were greater than those obtained with large column (25-45%): the difference in terms of momentum force, water recirculation and thus floc breaking phenomena occurred in large column should be responsible for these results. According to RTD experiments, tanks in series model were investigated with small column, while closely to ideal CSTR model were obtained with large column flotation: this can affect negatively the overall treatment efficiencies. In future, the continuous MIAF process with settling reactor or Sequencing Batch Reactors (SBR) should be applied in order to enhance the treatment of cutting oily-wastewater

title: A boundary rigidity problem of analytic function

description: In 1994, Burns and Krantz proved that an analytic function on the unit disc approaching a ̄xed point at the boundary with certain rate must be identity. This is essentially a boundary rigidity condition. In this thesis, we present the phenomena on simply connected domain with nice boundary and in the case of non-tangential limit. We also investigate the boundary rigidity problem on the Blascke's product

title: Bioactive compounds-producing endophytic fungi from kra thum na mitragyna javanica koord & val. leaves

description: One hundred and six endophytic fungal isolates were isolated from Mitragyna javanica leaves plants growing in Ayutthaya, Prathumthani and Amnatchareon provinces. These endophytic fungi were identified as Colletotrichum spp., Fusarium spp., Phomopsis spp., Phoma sp. Alternaria spp., Phyllostica spp. Xylaria spp., Penicillium spp., a Cladosporium sp. and the majority were mycelia sterilia. Crude extracts with ethyl acetate were examined for antimicrobial and anticancer activities. The antimicrobial activities were tested using paper disc diffusion assay technique against six reference microorganisms including Bacillus subtilis ATCC633, Staphylococus aureus ATCC25923, Pseudomonas aeruginosa ATCC9027, Escherichia coli ATCC25922, Saccharomyces cerevisiae TISTR5169 and Candida albicans ATCC1023. Seventy six percent showed antimicrobial activities against at least one tested microorganism with inhibition zones ranging from 7-40 mm. Six percent displayed a broad antimicrobial spectrum and twenty two percent inhibited the pathogenic yeast C. albicans. Moreover, the endophytic fungus isolate PT11 exhibited the strongest antimicrobial activity against all test microorganisms. Anticancer activities were examined with six human cancer cell lines including A375 ATCC no. CRL-1619(malignant melanoma), KatoIII ATCC no. HTB-103(gastric cancer), SW620 ATCC no. CCL-227(colorectal cancer), HepG2 ATCC no.HTB-8065 (liver cancer), BT474 ATCC no. HTB-20 (breast cancer), and Jurkat ATCC no. CRL-2063 (T-cell leukemia)) by the MTT method. The crude extracts of the endophytic isolates exhibited 58.49%, 60.38%, 58.49%, 45.28%, 61.32% and 31.13% cytotoxicity (cell viability &lt; 40%) against A375, Kato III, SW620, BT474, HepG2, and Jurkat, respectively. The endophytic isolate PT01 had the most specific activity against (0% cell viability) jurkat cells with potential induced 90.04% apoptosis cell death. The high potential endophytic fungus PT11 and PT01 were identified. Based on nucleotide sequencing of ITS region, they were closely related to 99% identity of Nodulisporium sp. and Phoma herbarum. The endophytic isolate PT11 showed strong antimicrobial and anticancer was chosen for further study of bioactive compounds. Isolation of culture both crude extract of the fungus isolate PT11 obtained pure compound 1 The compound 1 displayed apoptosis-inducing activities against the 66.35±1.46% Jurkat at with with IC50 37.5±0.76 µg/ml

title: Dental students' perceptions of learning environment in the Faculty of Dentistry, Naresuan University

description: Objective: To identify the dental students’ perceptions of learning environment in the Faculty of Dentistry, Naresuan University in the academic year 2009. Research Design: Cross-sectional descriptive study Participants: All dental students enrolled in the academic year 2009. Methods: Modified questionnaires, 43-items measure for pre-clinical phase (9 dimensions) and 39-items measure for clinical phase (7 dimensions), were developed for identifying the dental students’ perceptions of learning environment. A response was scored on a 1-5 Likert scale. The measures were ensured for its content and construct validity, and also reliability. Internal consistency reliability (Cronbach’s coefficient alpha) ranged from 0.70-0.91 in pre-clinical phase and 0.72-0.93 in clinical phase. The data were collected and analyzed using descriptive statistics. Results: The response rate was 88 percent. The overall mean score were 57.4 (out of a maximum of 90) for pre-clinical phase and 42.9 (out of a maximum of 70) for clinical phase indicating relative satisfaction with the perceived environment on both phases. “Health and stress” dimension as the lowest rank which was identified that there are many issues which need changing from both phases. The second lowest domain mean score, pre-clinical students identified “Physical environment” dimension, while clinical students indicated “Clinical environment” dimension. Conclusion: “Health and stress” dimension might be primarily concerned from this dental school for improvement or enhancement

title: Luminescent materials containing pyrene and carbazole for organic light-emitting diode

description: Three N-substituted 3,6-dipyrenylcarbazole derivatives (2PCT, 4P2C and 2PCP) were synthesized and applied as blue light-emitting or hole-transporting materials in organic light-emitting diode (OLED). In CH2Cl2 solution, the 4- (diphenylamino)phenyl substituent increases electronic-vibration coupling in the excited state whereas the substituents have no effect on the photophysical properties of the compounds in solid state thin film. Toluyl and 4-(diphenylamino)phenyl substitutents promote electro-oxidative coupling of 2PCT and 2PCP in solution. All derivatives show high thermal stability and can be used as both emitting and holetransporting materials in OLED. 2PCP exhibits the most promising optoelectronic properties as it gives the highest maximum luminance of 1,600 cd/m2 at 8.8 V with the lowest turn-on voltage of 3.8 V

title: Ankle morphometry for development of ankle prosthesis

description: The goal standard treatment of ankle osteoarthritis is arthrodesis. Alternatively, total ankle arthroplasty can improve function. No ideal design for this operation. The novel systerms are developing. The fundamental data to achieve that is ankle morphology. This study measure of 32 ankle by MRI which is 3D modality. The appropriate section was selected and measure the parameters the important to creat the ankle prosthesis. The parameters include the anteroposterior, mediolateral diameter of talus and distal tibia, sagitl radius of talus, malleolar width and malleolar axis. Some parameters can not measure directly. Because external rotation of normal ankle distort the true length, the adjust method by trigonometrical equation modify the parameters closed to reality. The comparison of the true talar AP length and the adjusted sagital talar length demonstrate no statistical and clinical significant. This modification method will applied to some parameters. The results shows the detail of 10 ankle parameters. Female group has smaller size than male group significantly except malleolar axis that is not different. The non adjusted parameters compare with the current data from Europe show sample population have smaller parameters except tibial width. If compare with data from China, the sample have no statistical significant except sagital radius of talus. But if compare both Europe and China with adjusted parameters, all parameters except tibial width, sample population are smaller significantly. The reasons of this phenomenon are different in race, the different measurement tool (2D or 3D) and the effect of external rotation of ankle. Ankle parameters play an important role to design and size the novel total ankle prosthesis. No system design for Thai people available now. This study shows that TNK (from Japan) is the most compatible one for Thai population

title: Ankle joint position sense of elderly engaged in difference types of exercise

description: To determine ankle joint position sense (JPS) of elderly engaged in difference types of exercise and no exercise. Subjects in this study were 160 Thai elderly aged 60-70 years old. They were classified in 4 groups, 40 persons per group, i.e. walking, tai chi, jogging, and non-exercise group. All of them were tested ankle JPS by passive reproduction test during weight bearing. The test foot was passively moved through a target position by an apparatus at a constant speed, 0.25 degrees per second. After that, the subjects indicate the joint position when they perceived that the target position had been reached. Mean values of two trials in each movement (total 4 movements i.e. inversion, eversion, plantarflexion, and dorsiflexion) were used for analysis. Furthermore, leg strength was tested with Senior’s chair stand test. The balance assessments were tested consequently with functional reach test, timed up&go test (TUG), single leg stance test, and the force platform test (BalanceCheck®) which presence of anterior-posterior (A-P) center of pressure (CoP) excursion, lateral center of pressure (CoP) excursion, and direction of maximum instability with eyes open and eyes closed either on a hard or soft surface. This study found that the non-exercise group had fall rate 30%, walking group 25%, jogging group 24.24%, and tai chi group 22.50%. Regarding joint position sense (JPS) test, exercise groups had significantly better ankle JPS for eversion, plantarflexion, and dorsiflexion in comparison with non-exercise group (p&lt;0.05). Whereas the leg strength of jogging group was greater than other groups. Otherwise, all three exercise groups had significantly better reaching distance and time of TUG test in comparison with non-exercise group (p&lt;0.05). The single leg stance time of all types of exercise groups were significantly better than non-exercise group (p&lt;0.05). Finally, the lateral CoP excursion with eyes closed on hard and soft surface of tai chi group were significantly better than other groups (p&lt;0.05). In conclusion, active elderly, tai chi practitioners, has best ankle proprioception and balance control, whereas jogging group has leg strength better than other groups. Their improvements in ankle proprioception and lower limb strength might reduce fall rate.

title: Acute mercury toxicity in tilapia (oreochromis niloticus), the pathological aspect

description: Mercury is one of most toxic heavy metals which can contaminate natural water sources. Humans can be exposed to mercury by consumption of mercury contaminated fish. Therefore, it is most appropriate model to use fish as environmental marker of mercury contamination. The purpose of this study is to investigate acute mercury toxicity in tilapia (Oreochromis niloticus) via histopathological, autometallography, Hg analysis by ICP-AES method and detecting metallothionein protein by immunohistochemistry techniques and metallothionein gene expression. Tilapias were divided into twelve experimental groups and one control group. The experimental groups included intraperitoneally injected with 0.5, 1, 2, 5 µg/g mercuric chloride (HgCl[subscript 2]), oral administration with 0.5, 1, 2, 5 mug/g HgCl[subscript 2] , and 0.5, 1, 2, 5 mug/ml HgCl[subscript 2] semi-static exposure groups. All fish showed the clinical appearance of respiratory failure followed by death in 2 and 5 mug/ml HgCl[subscript 2] semi-exposure groups on first day (day 0) of experiment. The major histopathological lesions includes tubulonephrosis, increasing immature nephrons, and deposit of crystal in trunk kidneys, increasing melanomacrophages centers (MMCs) in spleen, and losing of fat storage, degeneration of hepatocytes, and pancreatic atrophy in hepatopancreas. Following autometallography, silver-enhanced Hg grains were visualized in renal tubular epithelium, MMCs in spleen and in pancreatic acini in accordance with high mercury levels. The amount and location of visualized grains differ from routes and doses of HgCl[subscript 2]. The semi-exposure groups and higer concentration produced more grains than other routes and lower concentration. An expression of metallothionein (MT) protein revealed in renal tubular epithelium, MMCs in spleen, and pancreatic acini of 0.5, and 1 µg/ml semi-static exposure groups after day 9 and 6 respectively. From this present study, it concludes that pathological lesions, autometallography, expression of metallothionein protein by immunohistochemistry can be used to investigate acute mercury toxicity in tilapia.

title: Determination of sudan I-IV in chilli products using automated on-line solid phase extraction coupled with liquid chromatography-mass spectrometry

description: A rapid, accurate and precise method has been developed for the determination of Sudan I-IV in chili products using on-line solid phase extraction and LC-MS. Chili products were extracted with acetone and the analytes were cleaned up and enriched on an SPE column (C[subscript 18], 15-40 µm) through on-line SPE. Chromatographic separation was performed on a C[subscript 18] analytical column (2.1x150 mm, 3 mum) with gradient elution programming of 0.1% formic acid in water and 0.1% formic acid in acetonitrile. All four Sudan dyes were separated in less than 8 min. Using in-house validation data, a linearity coefficient of determination (R[superscript 2]) of more than 0.9997 was obtained. The limits of detection (LOD) and limits of quantitation (LOQ) were the same for Sudan I, II and IV and those values were 0.03 and 0.05 mg kg[superscript -1], respectively, and 0.04 and 0.1 mg kg[superscript -1] for Sudan III. The intra- and inter-day recoveries of the four Sudan dyes in chili powder were between 90.14-101.65% and 90.22-102.02%, respectively, with relative standard deviation (RSD) between 0.014-0.164% and 0.011-0.202%, respectively. The proposed method was used to detect Sudan I-IV in food samples such as chili sauce, roasted chili paste and dried chili. The results showed that Sudan I-IV were not found in real samples. To verify, real samples were spiked at 3 levels of standard Sudan dyes. The recoveries were found to be more than 90%. Therefore, the proposed method which is rapid, sensitive, less sample and solvent consumption could be applicable for the determination of Sudan I-IV in chili products.

title: Thai-Vietnamese relations during the first Indochina War (1946-1954)

description: To study the contributions of both the Vietnamese in Thailand and Thai people to the liberation movements in Vietnam during the First Indochina War and how the support from Thai people influenced the relations between Thai people and Vietnamese during this period. The study adopted a qualitative research method. Research techniques consisted of documentary research and interviews. Moreover, case studies were carried out in Nakhon Phanom and Udon Thani, where there was a large Vietnamese community and where the patriotic movements took place, in order to collect relevant data. The study finds that although the changes in Thai government from that of Prime Minister Pridi Banomyong (1946-1947) to the one led by Prime Minister Phibun Songkhram (1948-1954) had negative impacts on the Vietnamese community in Thailand, the Vietnamese community there still played a crucial role in supporting the war efforts in Vietnam. Moreover, it is undeniable that the patriotic movements of the Vietnamese received a lot of help from both Thai leaders, especially those in the Seri Thai group, and Thai people in the northeast. Furthermore, despite Phibun’s strict control of the Viet Kieu, relations between the Thai and Vietnamese were still good. This stemmed mainly from “Viet-Thai friendship” activities of the Vietnamese and also from Ho Chi Minh’s effort to promote friendship between the two peoples during his stay in Siam in the late 1920s. This partly accounted for the love and protection of many generations of Siamese for Viet Kieu. Siam became a place of providing human forces and was also a bridge for Vietnamese revolution to penetrate Vietnam.

title: Improvement of error concealment technique for H.264 scalable video coding

description: Today’s scalable video coding technology provides a solution to multimedia content delivery over heterogeneous network to various kinds of terminals. In this thesis, the main focus is on the application of spatial scalability, which enables the delivery of a single multimedia content to users with devices supporting low video resolution to high resolution. However, the ubiquitous delivery network still uses a packet-based approach which cannot necessarily offer a guaranteed Quality of Service (QoS). Some losses may still be corrupt the video bitstream. For a highly compressed H.264 video, a single frame loss may have a dramatic effect on the visual quality of the affected frame as well as its succeeding frames. Error concealment techniques are applied at the decoder side in order to estimate the lost information. Some works on error concealment for the H.264 video coding standard have been presented before, but their performance is found to be inadequate at times. In this thesis, we propose an improved error concealment scheme. We propose a motion estimation method which takes a weighted average of the motion vectors in a neighborhood of macroblocks from the previously decoded frame. Furthermore, the reconstructed frame is enhanced by filtering it with a hybrid median filter. The proposed algorithm was found to have an average gain up to 0.8 dB over the state of the art BL_Skip which was also reflected the better quality in the subjective evaluation. Further investigation also shows that the proposed algorithm is able to suppress the effects of error propagation on the frames succeeding the lost frame.
