title: Purification and characterization of glucoamylase from endophytic fungus EF6

description: Selective 25 endophytic fungi from stock culture of RCBC found that EF6 has maximum amylase activity was obtained after 8 days of incubation. Amylase from EF6 was extracted with 90% (NH[subscript 4])[subscript 2]SO[subscript 4] and purified by ion exchange chromatography using Q sepharose and gel filtration using Superdex75, respectively. The purity of amylase was 14.93 fold over the original culture filtrate with a 10.93% recovery activity. The estimated molecular mass of purified amylase is about 62 kDa. Optimum conditions for this amylase are 50-60 degree celsius, pH 5.0-6.0. Amylase still functions with the temperature below 60 degree celsius. At this point the activity was decreased to 43%. The activity of this enzyme can be increased with the present of Ba[superscript 2+] , Ca[superscript 2+] and Mg[superscript 2+] whereas AI[superscript 3+] , Ag[superscript 2+] and Cu[superscript 2+] acted as enzyme inhibitors. For various type of starch, tapioca starch is the easiest material for the digestion process. The K[subscript m] and V[subscript max] value were 2.63 mg and 1.25 mM/min, respectively. The purified amylase was indentified by mass spectrometry. The result shown that purified amylase may be glucoamylase (3.2.1.3) because partial amino acid sequences of that enzyme similar to glucoamylase (3.2.1.3) from Amorphotheca resinae.

title: Production of methyl esters from palm fatty acids in supercritical methanol

description: This study investigated the biodiesel production via a noncatalytic esterification reaction in supercritical methanol. The palm oil fatty acids were chosen as the raw material because of its availability as a low cost byproduct of palm oil industry. The variables affecting the methyl ester (biodiesel) conversion were investigated. which included molar ratio of fatty acids and methanol (1:1 to 1:12), reaction temperature (250 and 300 degree celsius) and reaction time (from 10 to 80 min). the results from this study showed that esterification of palm oil fatty acids in supercritical methanol gave the high conversion of 94% and was obtained at the molar ratio 1:6 (fatty acids: methanol) and at 300 degree celsius after 30 min. Furthermore, water whose content in fatty acid between 0-30 %v/v was found to lower the percent yield of methyl ester by hydrolyzing methyl ester back to fatty acids, and the degree of hydrolysis increased as water content and reaction time increased. when compare the result of methyl esterification of fatty acids in with methyl transesterification of purified oil, the result shows that the esterification of palm fatty acids requires lower operating conditions (Molar ratio and Time). when compared with conventional acid catalyzed process, supercritical methyl esterification of fatty acids required shorter reaction time and no neutralization process was needed.

title: Raw materials warehouse improvement in a mechanical component manufacturing plant

description: This study involves the warehouse improvement campaign for a mechanical components manufacturer based in Thailand. The focused company has been long suffering from its poorly-managed raw materials warehouse, which leads to untidy condition of storage area, inefficient space and poor materials utillization, raw materials pilferage and potential safety trouble. Through the research, the root causes are identified as lack of proper material storage equipments, inappropriate warehouse layout setup, unclear responsibility in the warehouse and poor warehouse operation. Based on exploration of root causes, six pertinent solutions (1) appropriate storage equipment design, (2) proper warehouse layout, (3) new operation procedure formulation, (4) material handlings system development, (5) safety and security measures establishment (6) proper inventory records are proposed. With Japanese 5S technique, improving activities are subsequently put into action. After implementation campaign, there have been several improvements. The warehouse physical condition is significantly improved. Space utillization is increased by 45%; Material storage, retrieval, and delivery are easier and faster by 60%, which also helps reduce production lead time. No injury and accident is reported during the period of one month after the implementation and potential safety trouble is eliminated. Storage area is well secured.

title: Semigroups admitting nearring structure

description: A system (N, +, .) is called a right [left] nearring if (i) (N, +) is an abelian group, (ii) (N, . ) is a semigroup and (iii) (x+y) . z = x . z + y . z [z . (x +y) = z . x + z . y] for all x, y, z [is an element of a set] N A semigroup S is said to admit a right [left] nearring structure if (1) (S, +, .) is a right [left] nearring for some operation + on S where . is the operation on S or (2) (S[superscript 0], +, .) is a right [left] nearring for some operation + on S[superscript 0] where . is the operation on S[superscript 0] For a nonempty set X, let G(X), T(X), P(X) and I(X) denote respectively the symmetric group on X, the full transformation semigroup on X, the partial transformation semigroup on X and the symmetric inverse semigroup on X. In this research, we characterize when G(X), T(X), P(X) and I(X) admit a right nearring structure and a left nearring structure. We also consider the corresponding idea for certain matrix groups and some particular semigroups.

title: Surface degradation of polyethylene terephthalate induced by UV-evanescent field

description: Poly(ethylene terephthalate), PET, is a commercial polymer with various applications in many industries such as textile, food and automotive industries. However, PET has hydrophobic property, thus it is not appropriate for some applications. Surface degradation induced by UV-evanescent is a novel technique for improving hydrophilic property of PET. The degradation was initiated under the total internal reflection of the UV radiation at the interface of specimen that contacted with internal reflection element(UV-ATR). This technique induces surface degradation and creates hydrophilic species on the exposed side of PET surface only, but it cannot induce the degradation of opposite side. These chemical changes were investigated by attenuated total reflection Fourier Transform infrared(ATR FT-IR) spectroscopy and FT-Raman spectroscopy. Since the change only occurs at the surface of PET (nanometer level), the mechanical properties of the degraded PET under UV-evanescent field are expected to be unchanged.

title: Stratigraphy and paleontology of marine triassic rocks in Amphoe Mae sot-Phop phra, Changwat Tak, Thailand

description: The aims of this study are to define lithostratigraphy of marine Triassic sedimentary rocks, identify radiolarians and clarify the geological age of these rocks in Amphoe Mae Sot-Phop Phra, Changwat Tak, northwestern part of Thailand. Marine Triassic rocks in the study area can be subdivided into 3 facies: pelagic limestone, turbidite sequence and chert sequence. The pelagic limestone is composed of well bedded gray and dark gray limestone with abundant radiolarian faunas and bivalve fragments, intercalated with thin black calcareous shale containing Halobia. Turbidite sequence consists of fine- to coarse-grained and thin- to thick-bedded sandstone interbedded with thin calcareous shale. Halobia has been observed in calcareous shales. Bedded chert is composed mainly of 3-10 cm thick, well bedded chert intercalated with thin shale containing abundant radiolarias. Radiolarias observed in bedded chert belong to 26 gerera and 43 species: Oertlispongus sp., Pseudostylosphaera japonica, Pseudostylosphaera spinulosa, Pseudostylosphaera timorensis, Pseudostylosphaera sp., Eptingium manfridi manfridi, Eptingium cf. manfridi manfridi, Eptingium sp., Pentaspongodicus symmetricus, Muellertortis cochleata cochleata, Triassocampe cf. deweveri, Triassocampe sp., Spongostephanidium japonicum, Spongostephanidium sp., Baumgartneria bifurcata, Falcispongus falciformis, Falcispongus sp., Staurolonche trispinosa, Canoptum rhaeticum, Canoptum laxum, Canoptum cf. levis, Canoptum sp., Vinassaspongus sp., Capnuchosphaera triassica, Capnuchosphaera cf. triassica, capnuchosphaera cf. deweveri, Capnuchosphaera sp., Paronaella sp., Paleososaturnalis sp., Orbiculiforma sp., Hagiastrum augustum. Pentaspongodiscus sp., Dumitricasphaera sp., Poulpus sp., Castrum peronatum, Xiphotheca longa, Xiphotheca sp., Annulotriassocampe sulovensis, Zhamojdasphaera latispinosa, Kahlerosphaera sp., Ferresium sp., Canesium sp. Based on the evidences of paleontology and petrology, the age of the rocks in the study area should be assigned as Anisian to Norian (Middle to Late Triassic) and they show that the rocks were accumulated on continental shelf to slope.

title: Synthesis and nucleic acid binding properties of novel peptide nucleic acids carrying beta amino acid spacer

description: A synthetic method for novel Peptide Nucleic Acid (PNA) carrying Beta-amino acid spacers has been developed. The PNA monomers in this research were pyrrolidine derivatives modified with 4 natural nucleobases at C-4 position. The thymine monomers were synthesized in all possible stereoisomers including "cis-D", "trans-D", "cis-L" and "trans-L". The adenine, cytosine and guanine monomers were synthesized only in "cis-D" configuration. These PNA monomers were coupled with Beta-amino acid spacers in an alternate fashion by Fmoc solid phase peptide synthesis. The spacers included in this studies were classified into three categories: acyclic (amino-oxy acetic acid, N-amino N-methylglycine), cyclic with one stereogenic center (D-aminopyrrolidine carboxylic acid or D-APC, L-aminopyrrolidine carboxylic acid or (L-APC), cyclic with two stereogenic centers [(1S,2S), (1R,2R), (1S,2R) and (1R,2S)-2-aminocylopentane carboxylic acids (ACPC)]. The solid-phase synthesis proceeded efficiently with more than 90% average efficiency for each individual coupling step. PNA sequences in 5-10 base lengths were successfully synthesized and were characterized by MALDI-TOF MS. Binding properties of these PNA with DNA were studied by UV-titration, T[subscript m], gel electrophoresis, circular dichroism and fluorescence experiments. These revealed that the cis-D pyrrolidine PNA containing the D-aminopyrrolidine carboxylic acid (D-APC) or (1S,2S)-2-aminocyclopentane carboxylic acid [(1S,2S)-ACPC] spacers can form stable 1:1 hybrids with DNA. The PNA-DNA interactions followed the Watson-Crick base-pairing rules (A.T, C.G). The cis-D/D-APC PNA also exhibited a strong preference for binding to DNA in antiparallel fashion.

title: Synthesis methodology affecting vanadium titanium silicalite-1 catalyst

description: Vanadium titanium silicalite-1 (V/TS-1) samples (Si/Ti = 50, Si/V = 100) are synthesized by using hydrothermal method. To determine a suitable synthesis method that can control the amounts of titanium and vanadium in the MFI structure of synthesized catalysts, the effects of synthesis methodology (the vanadium salt addition method) and type of vanadium salt (VCl₃, VO(acac)₂and V₂O[subscript 5] ) are investigated. The synthesized catalysts are characterized using various techniques such as XRF, XRD, BET, SEM, FT-IR, NH –TPD and ESR. The catalytic behavior is evaluated using the gas phase oxidation of 2-propanol (8 vol% oxygen, 5 vol% 2-propanol, balanced with argon). The catalytic reaction is carried out in a microreactor at a temperature range 100-500 degree Celsius, atmosphere pressure. This research shows that the vanadium salt addition method and the type of vanadium salt do not significantly affect the MFI structure as well as the reaction pathway. During the synthesis procedure, the vanadium species existing in the part of cation complex when it dissolved in aqueous solution is easier to be incorporated into the TS-1 structure than the ones exist in the part of anion complex. The surface area of the synthesized catalysts decrease inversely with the amount of vanadium incorporated. The NH₃ –TPD results indicate that the synthesized catalysts have two different types of acid site; the weaker one desorbed NH₃ at the temperature range 135-145 degree Celsius and the stronger one desorbed NH₃ at around 222-242 degree Celsius. For catalytic behavior, it is found that the synthesized V/TS-1 catalysts which have the vanadium active species derived from VCl₃ bonded on its surface are active in the 2-propanol oxidation and it can inhibit the dehydration and the combustion of 2-propanol. However, the ones which have the vanadium active species derived from VO(acac)₂ bonded on the catalyst surface do not be active in the 2-propanol oxidation but it can inhibit the 2-propanol combustion. Moreover, it is found that V₂O₅ is not the suitable vanadium source for this synthesis method because V⁵+ tends to stay in the anion complex which is more difficult to be incorporated into the TS-1 structure.

title: Synthesis of linear low-density polyethylene (LLDPE) / Alumina nano composite via in situ polymerization with metallocene catalysts

description: It is known that linear low-density polyethylene (LLDPE) can be synthesized by copolymerization of ethylene and 1-olefins using metallocene catalysts. However, the properties of LLDPE can be improved by adding organic or inorganic fillers. It should be mentioned that by adding nanoscale fillers into LLDPE, LLDPE-nanocomposites can be achieved. Among methods to produce polymer nanocomposites such as solution blending, melt mixing process and in situ polymerization, the in situ polymerization is perhaps the most promising method to produce the LLDPE-nanocomposite with an exceptional dispersion of nanoparticles inside the polymer matrix. This is due to the direct lingkage of active centers to the surface of nanoparticles. Therefore, it is necessary to immobilize the active centers onto nanoparticle surface or fillers. In this present study, LLDPE/Al[subscript 2]O[subscript 3] – nanocomposites were synthesized by the in situ polymerization with dried-modified methylaluminoxane (d-MMAO)/zirconocene catalyst. The nano-Al[subscript 2]O[subscript 3] was commercially obtained from Aldrich. The amounts of nanomaterials filled were also varied. Yields, activities, and polymer morphologies were discussed. It was found that the polymerization activity strongly depended on the [Al][subscript d-MMAO]/[Zr] ratios. The samples were further characterized using SEM/EDX, DSC, [superscript 13]C NMR, and GPC.

title: The growth and characterization of long chains of InAs quantum dot molecules

description: InAs quantum dot molecules (QDMs) are obtained from quantum dot (QD) overgrowth on nanopropeller templates which are grown by thin-capping-and-regrowth molecular beam epitaxy (MBE) process. The template structure is elongated along [110] crystallographic direction with QDs at the centre. They were used to grow QDMs aligned in that direction. Multi-cycles of thin-capping-and-regrowth with appropriate thin-capping thickness were investigated in order to create long nanopropeller templates. They are used as templates for the growth of long chain quantum dot molecules. By overgrowth of additional QDs in the final cycle of thin-capping-and-regrowth, satellite QDs are created on nanopropeller blades. With proper overgrowth thickness, long chain QDMs are successfully created on long nanopropeller templates. Lateral alignment of long chain QDMs contribute to anisotropic coupling among QDs. They lead to different magnitudes of wave vectors between [110] and [110] directions in the energy band structure of QDs ensembles. Hence, long chain QDMs demonstrate anisotropy of optical property, i.e. polarization dependence of PL spectrum, while as-grown QDs and small-group QDMs do not exhibit this property. The polarization degree of optical property agrees with the length of QDMs and their templates. However high QD density limits the anisotropic property due to increased QD coupling along the [110] direction.

title: The potential for tactical asset allocation in Hedge funds : evidence from index returns

description: Active portfolio management techniques and tactical asset allocation in particular may be growing in importance for traditional assets, but relatively little research has been conducted on hedge funds. We seek to build on the work of. Amenc (2002) which tried to predict nine CSFB/Tremont hedge fund indices utilizing financial variables and lagged index returns. Instead of predicting individual indices, we use Principal Components Analysis on twenty-five indices of two providers for the 1996-2005 period and find three common factors explain 64% of the variation between index returns. The three factors relate to equity market performance, and the relationship between corporate credit spreads and equity market performance and expected volatility. Further departing from Amenc (2002), we lengthen the forecast window to three and six months because a well-known "return smoothing" effect impacts the less liquid hedge fund strategies in particular, but may not be exploitable due to liquidity constraints. We develop regression equations to predict the tree factors, which incorporate financial variables on the equity market, credit spreads, and expected volatility. Although the first factor is only marginally predictable using market valuation ratios, the second and three factors appear to be more predictable. An asset allocation optimization over seven years (1999-2005) incorporating the predicted equations show modest improvement of five to eight basis points a month in realized return over an allocation using only historical factor exposures and returns.
