title: Formulation of oil-in-water emulsions containing spray-dried tamarind pulp extract and whitening efficacy test in volunteers

description: The aims of this study were to prepare spray-dried tamarind pulp extract and oil-in-water emulsions containing tamarind pulp extract. Physical and chemical properties were studied. Whitening and moisturizing efficacies of oil-in-water emulsion containing spray-dried tamarind pulp extract in volunteers were evaluated. Analytical method for determining tartaric acid in tamarind pulp, spray-dried tamarind pulp extract and oil-in-water emulsion containing spray-dried tamarind pulp extract were developed. In the preparation of spray-dried tamarind pulp extract, 10 %w/w acacia, inlet temperature 110 ºC, fan setting 50 were successful for spray drying tamarind pulp extract. Percent yield of spray-dried tamarind pulp extract was 55.73 ± 4.75 %, percent moisture content was 6.41 ± 0.64 %, spherical and smooth surface with slightly aggregated particles were obtained. The spray-dried tamarind pulp extract contained 7.83 ± 0.13 % w/w of tartaric acid. Stability of spray dried products were determined by keeping in tight, clear or light protected vials at accelerated temperature 40 ± 2ºC, relative humidity 75 ± 5% for 6 months. Amount of tartaric acid in spray-dried product was slightly decreased, finally, percent remaining of tartaric acid in both vials was as same as 93.16 % w/w. Eight percents by weight of spray-dried tamarind pulp extract was incorporated into oil-in-water emulsions. The prepared emulsions showed good physical and chemical stability at the ambient temperature for 6 weeks. Whitening and moisturizing efficacies of oil-in-water emulsion containing tamarind pulp extract using oil-in-water emulsion base as a control were tested in 35 healthy female volunteers which age in range 20 – 45 years. Tested and control sample of emulsions were applied on forehead twice per day for 6 weeks. Melanin value and moisture content were determined. After using emulsion containing spray-dried tamarind pulp extract, moisturizing value was increased in first week and significantly increased in three weeks more than using oil-in-water emulsion (p=0.000), melanin value at forehead was significantly decreased in four weeks more than using oil-in-water emulsion base (p=0.035).

title: Genetic variations of Noctiluca scintilllans in the inner gulf of Thailand

description: Noctiluca scintillans is the main causative red tide organisms in the inner Gulf of Thailand. Generally, this red tide could be observed around the river mouth areas including Chonburi and Petchburi coastal areas. However, the relationship between groups of N. scintillans in the inner Gulf of Thailand has not been known. Therefore, this study aimed to use the application of the molecular genetic technique to investigate genetic variation of N. scintillans. The samples were collected from 3 different locations in the inner Gulf of Thailand (Petchburi, Samotprakarn and Chonburi province), 2 locations from the eastern and southern part of the Gulf of Thailand (Chanthaburi and Chumpron province) and 2 sites from The Philippines and Indonesia. N. scintillans was cultured in ESM-culture medium, fed with Dunaliella. The DNA was extracted by salting out method for molecular genetic study. 48 ISSR primers were screened and 5 primers produced clear, polymorphic, and reliable ISSR profiles (814, SAS 3, 17898A, HB15 and 844A). The PCR product of COX I gene was about 450 bp in size. The analysis of the COX I sequences showed that there was no genetic variation among green N. scintillans samples. For ITS I region, the amplified PCR product was approximately 800 bp in size. The primer ITS_F1 was used to carry out sequencing reaction, 489 bp of DNA sequence were obtained, the sequence consisted of partial sequence of 18s rRNA (471 bases) and some part ITS region (27 bases). The sequence of PCR product of 56 bases were obtained by reversed primers ITS_R2. and contained part of 5.8s rRNA (41 bases) and part of ITS1 region (15 bases). The analysis of sequence obtained from ITS_F1 primers (489 bases) showed no differences among the samples collected from all stations. There was a problem to get the whole sequence of ITS I region of N. scintillans in this study. This might be caused by the variation between multiple copies of the gene within each sample since this gene has been reported that the multiple copies could be occurred.

title: Impact of zirconia modification on supported metallocene catalyst via ethylene/1-Octene coplymerization

description: For years, metallocene catalysts have brought much attention to research in olefin polymerization. As a matter of fact, it has led to an extensive effort for utilizing metallocene catalysts more efficiently. It is known that the copolymerization of ethylene with higher 1-olefins is a commercial importance for production of elastomer and linear low-density polyethylene (LLDPE). Metallocene catalysts with methylaluminoxane (MAO) have been studied for such a copolymerization. In particular, zirconozene catalysts along with MAO have been reported for a potential use to polymerize ethylene with 1-olefins. Nevertheless, it was found that a homogeneous metallocene catalytic system has two major disadvantages: the lack of morphology control of polymers produced and reactor fouling. Therefore, binding these metallocene catalysts onto inorganic supports can provide a promising way to overcome these drawbacks. Unfortunately, due to the supporting effect it is found that the catalytic activity of catalysts in the heterogeneous system is usually lower than the homogeneous one. It has been reported that many inorganic supports have been studied for years. In fact, silica has been one of the most supports used so far. However, the properties of silica itself may not be suitable. Hence, the modification of silica would be necessary. It was reported that zirconia modification on supports exhibited a promising enhancement for activity of many catalysts. In this thesis, impact of zirconia modification on the silica-supported metallocene catalyst was investigated. Experimentally, the zirconia-modified silica was prepared by impregnation of a zirconium (IV) n-propoxide solution onto the silica, then reacted with MAO. In order to study the catalytic behaviors during polymerization, the ethylene/1-olefin copolymerization reaction was carried out in a 100 mL semibatch stainless steel autoclave reactor. At first, 0.2 g of the supported MAO and the zirconozene catalyst (rac-Et[Ind]2ZrCl2) ([Al]MAO/[Zr]= 2270) and 0.018 mole of 1-olefin along with toluene were put into the reactor. The reactor was heated up to the polymerization temperature at 70C. By feeding ethylene (0.018 mole) into the reactor, the polymerization was started. The polymer samples were the chacracterized by means of 13C NMR and DSC. It was found that polymerization activities increased with Zr modification about 4 to 7 times. By means of 13C NMR, the Zr modification also resulted in higher degree insertion of 1-olefins resulting in low Tm of polymer obtained

title: Improvement of the phenylalanine dehydrogenase immobilization method for the production of phenylalanine

description: Phenylalanine dehydrogeanase (PheDH) produced from recombinant Escherichia coli was partially purified by ammonium sulfate precipitation and DEAE-Toyopearl column chromatography with a 20.2% yield and 2.6 purification fold. The enzyme had a molecular weight of 44.5 kDa. The enzyme was chemically modified with a series of group-specific reagents to identify essential amino acid residues. It was found that tryptophan, methionine, histidine and lysine residues may play an important role in the enzyme catalysis. Different immobilization methods were then used, i.e. immobilization via its amino groups, carboxylic groups and ionic interaction on various supports including silica, alumina, chitosan, epoxy-alumina and epoxy-chitsan. The immobilization of PheDH via its carboxylic groups by using carbodiimine gave the highest immobilized activity on silica. The optimum condition for enzyme immobilization was to activate carboxylic groups of the enzyme for 6 hours using 10 mM carbodiimide. Twenty five units of activated PheDH were then added to the silica (500 mg) which was activated with 2% (v/v) -aminopropyltriethoxysilane and incubated for 21 hours at 4°C. The activity of the immobilized enzyme was 1.41 U/g support with 5.17% of immobilization yield. When compared to the free enzyme, using coupled reaction with diaphorase, both enzymes showed the same optimum pH at 9.5 and the optimum temperature at 40ºC. The immobilized enzyme was stable over the pH range of 5.0-12.0 whereas the free enzyme was in the range 5.0-8.5. The immobilized enzyme had slightly higher temperature stability and storage stability at room temperature over the free enzyme. When the immobilized PheDH was used in batch production of L-phenylalanine, the immobilized PheDH produced L-phenylalanine 58% yield when incubated with 5 mol of phenylpyruvate at room temperature for 6 hours and retained its activity up to 84% after being used for three cycles. The immobilized PheDH was further applied for the production of amino acids using their corresponding keto acids as substrates, the product yields were ranging between 62.5-100%.

title: International cooperation and China's energy security concerns

description: China’s dramatic economic growth has made energy into a security issue. As China grows, so do its energy needs. Though China’s per capita energy usage ranks low globally, its enormous population makes it the second highest energy consumer with signs indicating that it will surpass the United States, the highest energy consumer, in the near future. China’s increased consumption has made China more active in securing energy. Its increased dependence on foreign energy imports is already driving up global prices and is raising fears of conflict as China’s search for energy converges with the interests of its neighbors and the United States. This thesis argues that while China’s energy security policy has stimulated concerns in developed oil dependent countries, it would not necessarily lead to conflict but would instigate increased aid and exchange of information over renewable energy technology as it is the most attractive alternative to current conventional fuel. The thesis explores the Chinese government’s involvement in various renewable energy cooperative efforts to assess the commitment to renewable energy on the part of China. Though renewable energy consists of a very small sector of energy consumption, and will continue to be so in the near future, renewable energy is better for energy security in the long run as it is available domestically. The current cooperation over renewable energy is not enough to make China more secure over its energy security nor is it enough to change the current situation in which China travels the globe to increase its energy supply but China’s participation in the various projects demonstrates its willingness to invest in renewable energy in the long term.

title: Measuring hospital efficiency of public hospitals under Office of Permanent Secretary of Ministry of Public Health in Thailand : a data envelopment analysis approach

description: The objectives of the study are to measure the hospital efficiency of public hospitals and identify the determinants of hospital efficiency. The first stage is to measure hospital efficiency and total factor productivity (TFP) index before and after universal coverage policy using DEA. The second stage is to identify the determinants of hospitals efficiency with Tobit regression analysis. All 805 public hospitals were included in the study. It is found that they are operating at 59% level of efficiency. Only 35 (4.3%) are technically efficient hospitals that were located on the frontier. About 16% of all inefficient hospitals have efficiency scores more than 80% and 56% of those have less than 60%. The large hospitals are more efficient than small ones. The average pure technical efficiency score of all public hospitals is 67.3%. There are only 130 (16.1%) pure technically efficient hospitals. In the inefficient group, 100% of regional hospitals, 81.8% of general hospitals have scores more than 60%. While 56% of community hospitals has scores less than 60%. The average scale efficiency score of all public hospitals is 88.6%. Most hospitals are operating very close to their optimal size. Regarding the pattern of scale inefficiency, decreasing returns to scale is the predominant form of scale inefficiency observed in regional and general hospitals while about 96.2% of small community hospitals were operating on increasing return to scale. For cost efficiency analysis, the average cost, technical and allocative efficiency scores of all public hospitals are 53.1, 56.9 and 93.4% respectively. The regional and general hospitals are more cost and technical efficient than community hospitals. All levels of public hospitals are much highly allocatively efficient at efficiency score more than 90%. The results of TFP index measurement showed that the scores of overall technical efficiency change, technical change and total factor productivity change are 1.300, 0.647 and 0.841 respectively. The scores of pure technical and scale efficiency change that decomposed of overall technical efficiency change are 1.037 and 1.253 respectively. The results of Tobit regression showed that the numbers of bed, occupancy rate, geographic location and service complexity are associated with technical efficiency. All aboved information could be used as a tool to support policy formulation process for health resuorce management of health care organization. In addition, these informations could be used as a guideline for hospital management.

title: Modification of ziegler–natta catalysts for propylene polymerization with organic and inorganic compounds

description: Propylene polymerizations were carried out with the direct addition of CaO in a semibatch type reactor. A certain amount of CaO enhanced the activity of Ziegler-Natta catalyst, but decreased isotacticity. The results indicated that CaO accelerated the initial polymerization rates and improved catalyst against deactivation without effects on melting point, crystallinity and morphology of the polypropylene obtained. The electron spin resonance (ESR) results revealed that CaO facilitated the reduction of Ti4+ species to lower valence active Ti species. In a similar way, the addition of the SiO2-supported MAOs moderately increased the activity of Ziegler-Natta catalyst, but unchanged the properties of the polypropylene produced. Catalyst activity was improved in the order of dried-modified methylaluminoxane (dMMAO)/SiO2 &gt; methylaluminoxane (MAO/SiO2) &gt; modified methylaluminoxane (MMAO/SiO2) &gt; SiO2-free &gt; SiO2. However, the stronger interaction between the MAOs and SiO2 support caused a decrease in polymerization activity. The observed polymer microstructure reflected an increase of active site concentrations rather than the increased propagation rate constant. The effect of the chemically different poisoning materials on the activity and isospecificity of the catalyst has also been investigated. The variations in deactivation power were listed as follows: methanol &gt; acetone &gt; ethylacetate. Addition of the poisoning materials caused decrease in the activity through the reduction of the number of active centers which was confirmed by a kinetic analysis with the stopped-flow method, whereas the catalyst isospecificity was hardly affected by these materials.

title: Data on arbuscular mycorrhizal fungal variables and soil properties from coffee plantations in Colombia

description: Data on soil properties from two coffee plantations located in Chachagüí, Nariño, Colombia. Three lots called Albergue (AL), Lajas (LA) and Mataredonda (MA) were sampled three times in May 2015, September 2015 and February 2016. 17, 19 and 20 sampling sites were established within the lots AL, LA and MA, respectively. Data presented here were used to perform discriminant analyses between the three lots with the contribution of the variables arbuscular mycorrhizal colonization percentage, arbuscular mycorrhizal spore density, easily extractable glomalin, bulk density, organic matter, pH, electrical conductivity, total nitrogen, water soluble phosphorus, extractable phosphorus, cation exchange capacity, available iron, phosphatase activity, ammonia monooxygenase activity, β-Glucosidase activity and clay content to the lot classification. Statistical analyses were carried-out with R (StatR, RWizard platform version 2.0). For conducting the multivariate analyses, a dataset for each sampling time was employed separately. When a row had a “not available” value for any of the 16 variables included, the row was excluded from the dataset, resulting in the three files presented here.
