title: Application of polyvinyl acetate as release controlling agent in 17-β estradiol implant matrices

description: To apply low and high molecular weight polyvinyl acetate (PVAc) as the release controlling agent in 2% 17β-estradiol (E2) implant matrix system, polyvinylpyrrolidone (PVP K30) was used as releasing modifier. Two plasticizers, triethyl citrate (TEC, a water-soluble plasticizer) or diethyl phthalate (DEP, a water-insoluble plastcizer) was incorporated to alter the flexibility of the matrix. Solid dispersion of E2 in polymer was prepared by solvent evaporation method and compressed in a mold to have an implant matrix of 2 mm in diameter and 10 mm in length. Physicochemical characterization of implants was performed using differential scanning calorimetry (DSC), X-ray diffractometry and FTIR spectroscopy. It was observed that E2 released from implants increased with increasing weight percent of plasticizers and PVP K30. E2 matrix implant with 20% DEP and 30% PVP K30 released 48.13% of drug in 28 days. Released kinetic of the PVAc implant matrix was best described by Higuchi model which indicated drug release by diffusion process. PVAc could be applied in E2 matrix implant for long term delivery.

title: Preparation of activated carbon from jatropha waste via phosphoric acid, potassium hydroxide, and zinc chloride activations

description: The preparation conditions of activated carbon from waste of jatropha were determined at various temperatures (500, 600, and 700oC), activation times (60, 120, and 180 min.), and ratios of raw material:chemical agent (1:0.5-1:2). The derived activated carbon was analyzed for its specific surface area, iodine number, average pore size, net iodine number, net surface area, bulk density, %yield, functional groups, and purity. The best conditions for the production of high surface area of activated carbon from jatropha seed cake and shell were the activation with potassium hydroxide at the activation temperature of 700oC (for both cake and shell), activation time of 180 (cake) and 60 (shell) minutes, and impregnation ratio of 1:0.75 (cake) and 1:0.5 (shell). At this optimal condition, the BET surface areas were 666 and 699 m2/g, and iodine numbers were 696 and 631 mg/g for seed cake and shell, respectively. The average pore size of activated carbon from jatropha shell with zinc chloride was the largest, at 9.86 nm. The structure of activated carbon were mainly amorphous, where the activated carbon with zinc chloride might contain the crystals of ZnO and Zn5(OH)8Cl2 .H2O on the carbon surface. The surface of activated carbon might contain several functional groups including aromatic, benzene derivatives, and hydroxyl groups. When %yield was included in the consideration, the best combination for the production of activated carbon was to use jatropha seed cake as a raw material, and zinc chloride as activating agent as this provided the yield at as high as 0.64 g activated carbon/g raw material.

title: Outage behavior of cooperative diversity schemes with relay selection

description: New digital communication standards have been raised to support the dramatic rise of the capacity demand and to provide the comprehensive coverage. Thereby, many researchers have taken on the technical challenges in the part of wireless interface, which is the bottleneck of a communication system, due to its limited channel. The important idea that can improve the system in a major way is to use cooperative diversity, especially when the coherence time is too long compared to the transmission block, and the interleaver technique or channel coding is not long enough to combat the fading efficiently. In this thesis, we are particularly interested in the cooperative diversity schemes that employ multiple relay nodes with relay selection protocol. For systems employing diversity techniques, the outage probability and the outage capacity are the important figures of merit. We analyze both the outage probability and the outage capacity for such cooperative diversity schemes. The analyses show many insights, for example, there exists a signal-to-noise ratio threshold, below which some cooperative diversity schemes outperform direct communication. The obtained expressions are exact, simple, and applicable to arbitrary network topologies and signal-to-noise ratios in Rayleigh fading channels. Our results can serve as guidelines for efficient system design of cooperative diversity schemes and deployment of cooperative networks.

title: Behavior of vertical and lateral load on T-Shape barrette and bored piles

description: The large diameter long bored piles are commonly used as foundation for high-rise buildings and bridges in Bangkok, Thailand. However, in case of high loading capacity requirement in the limited area, the use of barrette pile foundations would make a better alternative to bored piles. Generally, the main load component of pile foundation is vertical loading. For some structures, piled-foundation might be designed to resist the high lateral loading. The T-shape barrette pile is, therefore, proposed to be an alternative deep foundation not only to support vertical loading but also to resist high lateral loading. The pile under vertical and lateral loading is the soil-pile interaction problem which concern to many parameters in both structure and soil properties. Therefore, the selected parameters for analysis and design pile size, pile length and number of piles in footing must be considered with allowable load, allowable settlement and movement of soil and piles. In this research, The full scale static pile load tests were conducted to verify the vertical and lateral load capacities of T-shape barrette and bored piles with pile tip founded in the second dense silty sand layer about 55 m depth below ground surface. The analyses were performed using PLAXIS 3D Foundations, the 3D Finite Element Method (FEM) Program. The test results show that the shear plane is not positioned along the T-shape barrette shaft perimeter under vertical loading. For piles under lateral loading, apparently, possible concrete cracking in the FEM analysis of the pile significantly affects the calculated results of both T-shape barrette and bored piles. If concrete cracking effect is neglected in the numerical analysis, the results tend to overestimate the pile capacity. For the design approach, the back analysis suggests that input soil stiffness for T-shape barrette should be about 3 times of empirically calculated value for bored pile to predict deflection values before concrete cracking. Besides, that the flexural stiffness of T-shape barrette should be decreased by approximately 70% to obtain the lateral movement after concrete cracking.

title: Robust constrained model predictive control for piecewise affine systems using saturated linear feedback controller

description: Piece-Wise Af_ne (PWA) systems belong to a promising class of hybrid systems. PWA systems can be considered as a natural model class for nonlinear systems since they can be used to approximate a range of nonlinearities by a set of af_ne/ linear function. This class of representation is still an active research area. This thesis presents the application of the Robust Constrained Model Predictive Control (RCMPC) design framework for discrete-time PWA systems under parametric uncertainties. In order to guarantee robust performance, the control law applies a parameter-dependent Lyapunov function which corresponds to the vertices of the polytopic uncertainties of the PWA systems. We consider saturated linear feedback control law in deriving tractable and robustly stable closed-loop PWA systems. The design approach is divided into two parts. The first part focuses on the design of a robust control law for uncertain time-varying PWA systems with delay-free. The second part emphasizes on the design of a robust control law for uncertain time-varying PWA systems with timedelays. Moreover, we consider two sub-parts of the systems, which are PWA systems with timeinvariant delays and PWA systems with time-varying delays. The design formulations are then cast as a Linear Matrix Inequalities (LMIs) optimization problem and the algorithms are solved on-line to guarantee the robust stability of the closed-loop systems. Once a feasible solution is found, the system is guaranteed to be asymptotically stable for time kappa is more than The numerical results demonstrate that the framework adopted here is suitable and effective.

title: An experimental and numerical study of asphaltic concrete under tropical environments

description: The asphaltic concrete is an essential material for flexible pavement construction. Its behaviour is however so complicated, especially the behaviour depended on the change of temperature and/or stain rate. The pavement design of Thailand has been still based on the standard of foreign countries. In fact most of them were created and developed based on the database observed under their environments. Those databases and methods from foreign countries may not be suitable to the condition of Thailand thereby this research focuses on the asphaltic concrete behaviour under the various temperatures and the changing rates which relate to the environment in the tropical countries such as Thailand. This study consists of two main parts which are to study the asphaltic concrete behaviour based on the laboratory test and to analyse the test result and then to model the asphaltic concrete behaviour. The former is composed of four tests which are the static and the cyclic indirect tensile tests and the static and the cyclic unconfined compress tests. All test results are analysed using the conventional pavement engineering method such as analyses result employing the time-temperature superposition. By all results of analysis they can be next used to produce the database for the road design in Thailand. The later studied the behaviour of asphaltic concrete can be used to validate the constitutive model based on the hyperplasticsity theory. The main feature of this theory is that it enables to define the constitutive law by setting the potential energy equation and the flow potential equation. This constitutive model also relies on the kinematic hardening plasticity and the rate-dependent plasticity principle. Following this study both the model and the parameters can be future benefits to numerical application in the pavement analysis and design.

title: Strategies for blank holder force and pressure design through fea simulation in sheet hydroforming

description: To determine loading paths of blank holder force (BHF) and pressure in hydromechanical deep drawing (HMD) process of the parabolic cups is aim of this research. The process of HMD, the sheet is formed against a counter pressure in the pot rather than a female die in regular stamping operation. Successful HMD process requires the optimum relationship of the key process parameters. Excessive BHF leads to the part thinning. Conversely, insufficient BHF can lead to flange wrinkle. In case of pressure, excessive pressure leads to the part thinning. In opposition, insufficient pressure can lead to side wall wrinkle. Trial-and-error for the process design can be very time consuming. Finite element method coupled with optimization technique is applied to determine the proper constant BHF and proper linear counter pressure. The adaptive finite element method coupled with fuzzy logic control is applied to determine loading profiles of BHF and pressure just one simulation. The parabolic parts are used to investigate. The thinning is the index to compare the quality of part. The crack and wrinkles will be disappeared at the end of stroke.

title: Influences of gasohols on glass fiber reinforced polyamide 6 composite

description: In this study, the influences of gasohol on physical and mechanical properties of glass fiber reinforced polyamide 6 (PA6) composites were investigated. The pellets of neat PA6 and PA6 compound with 15 wt% and 30 wt% glass fiber were used. Test specimens were prepared by compression and injection molding machines.These specimens were immersed in 4 different test fuels, namely, C(E0)A, C(E20)A, C(E85)A, and C(E100)A at room temperature for 16 weeks. The test fuels were changed every 3 weeks. Morphology, water absorption, mass and dimension change, tensile, flexural, compressive and impact properties were examined by scanning electron microscope (SEM), balance, universal testing machine (INSTRON) and impact tester, respectively. The experimental results showed that the PA6 matrix had an excellent adhesion to glass fiber reinforcement. The glass fiber could improve the mechanical properties of the composites and mass and dimensional stability of specimens by reducing amorphous region while increasing crystalline region. Test fuels containing alcohol, i.e. C(E20)A, CE(85)A and C(E100)A affected the tensile strength, flexural strength and Young’s modulus of both unreinforced and reinforced PA6 composites more than C(E0)A due to adsorption of water and alcohols from C(E20)A, CE(85)A and C(E100)A by both unreinforced and reinforced PA6 composites.

title: Vector magnetic anomaly of kilns at Sri Satchanalai Ancient City, Changwat Sukhothai

description: Sri Satchanalai ancient kiln which produced the Sangkalok (ancient ceramic) around 13th to 16th century (all 800-500 years ago) were selected for measuring the ancient magnetic direction of the kiln. Two kiln i.e. kiln no.1 and kiln no.2 were studied, fluxgate magnetometer was employed and the results show that the magnetic susceptibility vary from 50-500 nT. This figure indicate that magnetic susceptibility of the kiln were high enough to be investigated. Moreover, proton magnetometer was also use. The results show that proton magnetometer step two is most suitable. The total magnetic intensity varies from 42,000-44,000 nT. Vector magnetic gradiometer was invented. It consist of three axis sensors that are x, y and z. This equipment can measured in both horizontal and vertical magnetic direction. The data from this measurement are enormous. It need special computer software to calculate and compile. The result show that there is four degrees of mis-alignment and offset about 100-200 nT from the theoretical calculation. Therefore, the newly invented vector magnetic gradiometer need to be improved both hardware (more sensitive fluxgate magnetometer) and computer solfware.

title: Thermomechanical properties of polybenzoxazine modified with dianhydrides

description: To study the mixture between benzoxazine resin (BA-a) and dianhydrides, i.e. 3, 3’, 4, 4’ benzophenonetetracarboxylic dianhydride (BTDA), pyromellitic dianhydride (PMDA) or 3, 3’, 4, 4’ biphenyltetracarboxylic dianhydride (s-BPDA) at various mole ratios of BA-a: dianhydrides on thermal and mechanical characteristics. The glass transition temperature (Tg) and the storage modulus (E’) values of BA-a: BTDA, BA-a: PMDA, and BA-a: s-BPDA films were observed to be significantly higher than that of the neat polybenzoxazine (PBA-a) owing to the enhanced crosslink density. This greater crosslink density resulted from esterification reaction between the hydroxyl group of polybenzoxazine and the carboxylic group of dianhydride, which formed by thermal curing. The maximum Tg values of BA-a: PMDA &gt; BA-a: s-BPDA &gt; BA-a: BTDA were observed at an alloy composition of 1.5: 1 mole ratio. Moreover, the degradation temperature (Td) reported at 10 percent weight loss under nitrogen atmosphere and char yield at 800 degresss celsius of the polymer alloys were found to be much greater than those of the neat polybenzoxazine (PBA-a) while the calculated LOI of all BA-a: dianhydride alloys were above the self-extinguishable limit i.e. &gt; 26. In addition, tensile strength, tensile elongation at break, tensile modulus, and toughness of PBA-a increased by alloying with BTDA or PMDA or s-BPDA. These results suggested the alloys to be casted to yield tougher and stronger films. The ultimate mechanical and thermal properties for BA-a: dianhydrides were also obtained at 1.5:1 mole ratio. The obtained alloy sample is appropriate for an application as polymeric film for high temperature resistance material such as electronic packaging, thermal resistance coating and matrix for composite materials.

description: A lectin was purified from the rhizomes of Curcuma amarissima Roscoe by aqueous extraction, fractionation with 80% saturated ammonium sulphate, and a combination of affinity and gel chromatography on ConA Sepharose and Superdex G-75, respectively. The molecular mass of the purified lectin was of 32.4 kDa, as estimated by SDS-PAGE. This purified lectin contains 33.21% of carbohydrate and show the specific activity for rabbit and rat erythrocytes but not for mouse, guinea pig, goose, sheep and human blood groups (A, B, AB and O) erythrocytes This lectin is stable at temperatures below 40 degerss calsius, but the hemagglutinating activity was reduced to halved when it was heated up to 45-85 degerss calsius and completely lost activity at 95 degerss calsius. Surprisingly, the hemagglutinating activity is more stable at 80 degerss calsius than at 70 degerss calsius, and was rapidly inactivated at 90 degerss calsius. It showed a maximum hemagglutination activity within the pH range of 8-11. Metal ions including Hg [superscript 2+], Co[superscript 2+], and EDTA can inhibit its activity whereas Mg [superscript 2+], Mn [superscript 2+], Fe [superscript 2+] and Ca [superscript 2+] were no effect. The deduced amino acid sequence of an internal tryptic peptide sequence of this purified lectin showed sequence similarity (homology) to other members of the leucoagglutinating phytohemagglutinin precursor family, whilst the complete lectin inhibited the in vitro growth of three plant pathogenic fungi, Fusarium oxysporum, Exserohilum turicicum, Colectrotrichum cassiicola, at a concentration of 17.5 to 35 µg, and four microbial, B. subtilis, C. albican, E. coli, and S. aureus at concentration ≥ 0.446, 0.446, 0.223, 0.892 mg/ml, respectively. Furthermore, this lectin showed in vitro cytotoxicity against the BT474 breast cancer cell line with IC[subscript 50 ] of ~21.2 micro gram Additionaly, IC[subscript 50 ] for an alpha-glucosidase activity is 0.073 mg/ml protein.

title: Oxidation stability of hydraulic lubricants from vegetable oils

description: The lubricants produced from petroleum base stock are generally toxic to environment and difficult to dispose after use. Vegetable oils can be used as an alternative base stock for lubricants besides petroleum base because of their excellent lubricity, biodegradability, viscosity characteristic and low volatility. The hydraulic lubricants from vegetable oil were manipulated in this research. Their physical properties including viscosity, viscosity index, flash point and four- ball wear were investigated comparing with those of commercial hydraulic lubricants. OIL-HR, lubricants produced from rice bran oil was exhibited excellent lubricity and viscosity–temperature properties in the same level as commercial industrial lubricants. The oxidation stability of manipulate hydraulic lubricants from soybean oil and rice bran oil under the tested conditions of oven oxidation test in the presence of 0.5% diphenylamine exhibited excellent antioxidant property. The copper corrosion behavior of hydraulic OIL-HC, OIL- HP, OIL-HSF and OIL-HR, lubricants produced from coconut, palm, sunflower and rice bran oil, revealed these blended oils were classified into 1a class, which showed good anticorrosion. The hydraulic lubricant from rice bran oil displayed good anticorrosion and viscosity-temperature characteristic.
