title: Analysis of ethanol reforming process for hydrogen production

description: In this study, a thermodynamic analysis of steam reforming and autothermal reforming processes for the production of hydrogen from ethanol is performed. The aim is to determine optimal operating conditions for a hydrogen production system. Operational constraints, i.e., operating temperature and carbon formation, are taken into account. The simulation results on steam reforming and autothermal reforming show that feed stream with a high water-to-ethanol ratio is favorable for increasing hydrogen production and avoiding carbon deposition on catalyst. It is also found that at each water-to-ethanol ratio, there is an optimal temperature for steam reformer operation to provide the highest hydrogen yield. The carbon formation is favored at low operating temperatures and water-to-ethanol ratio. For autothermal reforming, a feed preheating temperature significantly affects oxygen-to-ethanol ratio; a higher preheating temperature can reduce the amount of oxygen required for preheating reactants and supplying endothermic reaction in the reformer under adiabatic condition. The carbon dioxide capture method using monoethanolamine (MEA) as solvent is studied in order to reduce carbon dioxide emission and purify hydrogen product. This process can purify hydrogen product stream from steam reforming system up to about 97 mol%

title: Analysis of a corporate identity color and its effect on corporate image

description: To investigate an effect of the corporate identity color on the corporate image. Firstly, the influence of corporate identity color on the audience’s memory was observed. Secondly, the effects of color on the corporate image in general purpose and graphic arts industry were observed through visual assessments. Twenty-nine color samples selected from the PCCS color system were employed to assess the feeling of the observer by means of the semantic differential scale questionnaire. The color samples consisted of six hues (Red, Orange, Yellow, Green, Blue, and Purple) varied in four different tones (Vivid, Light, Soft and Deep) and three achromatic samples (White, Grey and Black). The experimental raw data were analyzed to derive the correlations coefficient between visual results and CIE colorimetric values. In addition, a difference between the visual results of general purpose and graphic arts industry was analyzed by using an independent samples t-test. The results showed that the observers were able to recognize the company as a corporate identity color while the interpretation of the corporate images were varied depending on the dimensions of color such as lightness chroma and hue. Moreover, by using independent samples t-test, the corporate image of reliability, service and stability were found to be statistically different at a significant level of 0.05

title: Direct synthesis of benzaldehyde from toluene

description: This research studied the direct synthesis of benzaldehyde from toluene and hydrogen peroxide using titanium silicalite-1 catalysts modified with different amount of Al. The reaction is carried out at reaction temperature 70°C and 90°C, and toluene per hydrogen peroxide molar ratios 1:1 and 2:1. It is found that all modified catalysts yield benzaldehyde as the major product with o-cresol and p-cresol as by products. The experimental results also show that Al added into TS-1 promotes the formation of benzaldehyde and suppresses the formation of cresols. Too much Al added, however, will decrease the catalytic activity of the modified catalysts. Benzaldehyde selectivity increases with the increase in reaction temperature. On the contrary, benzaldehyde selectivity decreases if toluene per hydrogen peroxide molar ratio is increased from 1:1 to 2:1. This is due to toluene will cover the catalyst surface, leaving lesser hydrogen peroxide on the catalyst surface. The formation of benzaldehyde which requires twice amount of hydrogen peroxide than the formation of cresol, therefore, decreases

title: Soil analysis data for forest islands dispersed on savannas of Roraima, northern Brazilian Amazonia

description: The dataset provides information on soil texture and fertility for twelve forest islands (or forest fragments) dispersed on savannas of Roraima, northern Brazilian Amazonia. The sampled forest islands are representations of semideciduous seasonal forests with paleoclimatic origin naturally dispersed over a landscape with low altitude (~90 m a.s.l.). They are situated in a forest–savanna ecotone and have been exposed to frequent anthropogenic impact as selective logging and understory forest fire. The fieldwork was carried out between 2013-2014, when were taken soil cores from a profile to 100 cm depth, divided into six intervals (0–10, 10–20, 20–30, 30–40, 40–50, and 90–100 cm). The samples were arranged equidistantly along transects to represent the variability in texture and soil fertility between the edges and the interior (gradient of position) of each fragment (see details in Turcios et al. 2016. Soil charcoal as long-term pyrogenic carbon storage in Amazonian seasonal forests. Global Change Biology, 22: 190–197). The dataset is presented in two files: (i) study_site - a figure indicating location of the study area, and (ii) soil_analysis – a file with the identification of each sampling unit (forest island), geographical location (lat / long - WGS84), and information on texture (% - sand, silt, clay) and soil fertility (chemical variables) associated to signs of presence-absence (yes or no) of cattle, understory fire and selective logging. This dataset was supported by the ‘Ecology and Management of Natural Resources of the Roraima Savanna’ project (PPI-INPA 015/122) and the National Council for Scientific and Technological Development of Brazil (CNPq 303081/2011-2), under a fellowship for R.I. Barbosa. M. M. Turcios and M. M. A. Jaramillo were supported by postgraduate fellowships from the Organization of American States (OAS), while L.C.S. Carvalho was supported by a fellowship from Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES/PNPD).

title: A randomized controlled trial of acupressure backrest in chronic low back pain: a study in office workers

description: The aim of this study was to investigate the effects of acupressure backrest and to compare those effects between the randomized and preferred groups among office workers with chronic low back pain. Ninety-six participants were randomly assigned to either no intervention (n=32), backrest with acupressure point (n=32) or backrest without acupressure point groups. The participants (n=37) who wished to try the backrest were recruited to the preference group. The study outcomes were pain, disability, psychological aspect, quality of life, spinal mobility and physical performance at baseline, 2, 4 weeks, 1, 2, 3 months. For between groups analysis, the results indicated that backrest with and without acupressure point groups showed a significantly difference in pain, disability, spinal mobility, physical performance and well-being compared to the control group (P&lt;0.05). Comparing between the backrest with and without acupressure point groups, there was no significant differences between them in the majority of outcomes. For within subject effect, the backrest with and without acupressure point groups showed significant improvement in pain, functional disability, quality of life, spinal mobility and physical performance at most of the points measured (P&lt;0.05). While a reduction of participants taking medication was presented in the acupressure backrest group only during the follow-up period. No significant difference found between the allocated and preferred backrest groups for pain and disability. These findings suggested that the acupressure backrest could improve low back pain conditions and reduce the medicine usage. Preference was not a powerful moderator to the significant treatment effect.

title: Effect of ultraviolet radiation on pigment and polyamine contents related to photosynthetic system in cyanobacterium Synechocystis sp. PCC 6803

description: This research studied about the effect of ultraviolet or UV radiations on intracellular pigments and polyamine contents associated to photosynthesis in cyanobacterium Synechocystis sp. PCC 6803. All UV radiations (UV-A, UV-B, and UV-C with intensity of 10, 1.3, and 1.3 w•m-2, respectively) had slight effects on growth but highly significant changes on intracellular pigments within 24 h-treatment. Chl a content was decreased within 24 h about 10 – 40% whereas carotenoid content was decreased about 30 – 80%. All UV radiations reduced the photosynthetic efficiency within 3 h-treatment by 90 -98% decreasing. For total polyamine content, all UV radiations affected decreasingly on polyamine contents in whole cell and polyamines associated with thylakoid membranes within 24 h-treatment. The dominant polyamine responded to UVs was spermidine. Moreover, the polyamines associated with photosystem was determined. The photosynthetic proteins on thylakoid membranes were solubilized from thylakoid membranes and separated those proteins of photosystems using sucrose gradient ultracentrifugation at 144,000xg, 4 ºC for 14 h. Polyamines associated with PSII which located at the boundary of 30 – 40% sucrose layer (F5) and the boundary of 40 – 50% sucrose layer (F6) were significantly changed under UV treatments. However, the level of polyamines associated with PSI which located at 10% sucrose layer (F2) was not changed. Altogether, polyamines had the important response to UV stress and were identified their association with photosynthetic systems.

title: Effects of temperature on gonadal development of the snail-eating turtle malayemys macrocephala

description: Increase in average temperature that gradually warms the earth can change both physical and biological environments and affects survival of organisms. Reptiles, especially freshwater turtles, are considered as susceptible species since their development is dependent on incubating temperature. Current research thus aimed to examine effects of temperature on somatic and gonadal development of the snail-eating turtle, Malayemys macrocephala, a native and the most common freshwater turtles in Thailand. Turtle eggs were collected from rice fields in Bang Ban district, Phra Nakhon Si Ayutthaya province from December 2011 to February 2012. Based on 5 field surveys, a total of 712 eggs from 126 clutches of M. macrocephala were collected and transported to a laboratory. Eggs were incubated in microprocessor-controlled incubators at three different temperatures (26°C, 29°C and 32°C)and randomly dissected on weekly basis until hatch. It was found that incubation period, time from beginning of incubation until hatch, was not significantly different among temperatures (115+11, 115+20 and 109+18 days, respectively). Development of M. macrocephala was studied in reference to the standard stages of turtle development based on morphological characters. Growth patterns as indicated by stage of development and carapace length were significantly different among temperatures. At high temperature (32 °C), turtle embryos grew significantly more rapid than low temperature (26 °C) and pivotal temperature (29°C). However, embryos incubated at high temperature had a significantly higher incidence of malformation than other temperatures. Histological analysis for gonadal development showed that incubating temperature could affect differentiation of gonads into ovaries or testes as well as degree of development of the gonad, suggesting that M. macrocephala exhibits a temperature-dependent sex determination. Overall, the results indicated that incubating temperature is an important variable affecting both somatic and gonadal development of M. macrocephala. The data from this study could be used to assess the impact of global trend of temperature change and potential mitigation measure to reduce this impact on the freshwater turtle in order to conserve their natural populations.

title: Inventory management : a case study of an electric industry company

description: One of the most important factors in business operations is inventory, especially Raw Material, as it protects against fluctuation in supply and realizes economy of scale for a company. Nevertheless, inventory is a costly asset. Reducing inventory levels allows a company to increase liquidity and to be more responsive to customer’s demands. This case study proposes the use of ABC Classification to classify high-impact raw-material in an electronic industry company and the use of lot-sizing to improve the procurement process. The inventory performance measure of the case study company is in Inventory Turnover Days where a target of no more than 10 days is set. ABC Classification and other prerequisites results in 12 items from 3 different refrigerator models on which further study is conducted. Comparing results from lot sizing heuristics showed that the Part-Period balancing heuristic performs best, resulting in a total cost difference of 12.09% from the optimum values obtained from Wagner-Whitin algorithm. The Part-Period Balancing heuristic also came as close to within 3% of the optimum values for two parts. Implementing the Part-Period Balancing heuristic to just the 12 selected items, out of 1,008 possible items resulted in a considerable Inventory Turnover Days reduction of 0.5 days. As Lot Sizing heuristics and algorithms leave little or no inventory at the end of each period, Safety Stock levels for the aforementioned items are established to guard against stock-outs.

title: Sustainable provincial power development plan : case study of Nakhon Si Thammarat Province

description: The study was carried out to survey an energy outlook as well as renewable energy potential in Nakhon Si Thammarat province in order to enhance energy security and energy self-reliance of the province. Most information were reviewed from reports and statistical data prepared by various related agencies and academic institutes. Dialogues and in-depth interviews were also carried out to collect opinion and suggestion from stakeholders, including Provincial Electricity Authority, provincial and local government agency, power producer business, Member of the Parliament of Nakhon Si Thammarat province, community’s leader, the nuclear and coal projects’ antagonists, and both local and national energy policy makers. Regarding to electricity outlook of the province, the study found that electricity generated in the province exceeded its demand, which implies that the province exports electricity to other provinces in the southern part of Thailand and trends to be one of electricity supplier targets for the country. However, electricity generation in the province mainly relies on natural gas, while generating from renewable source only low proportion (installation capacity as of 2011 was only 42 MW). Even though the previous study reported that Nakhon Si Thammarat province had high potential of renewable energy for electricity generation as much as approximately 3,200 MW (without dependable factor), but only about 1,600 MW if multiplied with EGAT’s dependable factor using for PDP2010. In order to promote renewable energy development as well as enhancing energy security and energy self-reliance, the province should have its own power development plan (PDP) which can be integrated with the national plan. Therefore, this present study has proposed a model for sustainable provincial PDP process, where its path way to develop the plan that would consist of accredited committees including provincial PDP committee, provincial energy assumption sub-committee and provincial renewable energy research sub-committee to work under public organization structure and function. However, the authorized local and provincial administratives would be decided by law enforcement and governmental policy. In addition, policy integration, renewable energy database and technology innovation were found to be key successful factors for sustainable energy planning.

title: Formation of N₂O and SO₃ on V-W-Mo/TiO₂ catalysts prepared from sequential loading method during the selective reduction of NO with NH₃

description: This work studies formation of N₂O and SO₃ on V-W-Mo/TiO₂ catalysts that prepared from sequential loading method during the selective catalytic reduction of NO with NH3. The formation of N₂O and SO₃ testing is carried out in a temperature range 120°C-450°C. The results indicate that all catalysts produced N₂O at high temperature and significant increasing of N₂O when NO conversion decreases. The formation of N₂O occurs from the reaction between NH₃ on surface of catalyst and NO in gas phase followed Eley-Rideal mechanism. It also found that decreasing amount of W content tends to increases the amount of N₂O, but decreasing amount of Mo content was less affected. In the part of formation of SO₃, it is found that overall the catalysts studied, the oxidation of SO₂ to SO₃ does not occur.

title: The chemistry of titanium precursors, butylchloride and cocatalyst for improvement of catalyst activity in ethylene polymerization

description: The improvement of Ziegler-Natta catalyst activity can be achieve by adjusting the related factors. This research was aimed to investigate the effects of titanium precursors, butylchloride and cocatalyst on the ethylene polymerization activity. The amount of precursors was varied, and then polymerized at 80 0C for 2 h. The results showed that the decrease of catalytic activity was observed when the amount of titanium (IV) alkoxide was increased. Inversely, an increase of butylchloride amount resulted in an increase of catalytic activity Moreover, the effects of types and amount of cocatalyst were also investigated. The obvious increase of catalytic activity was obtained when the amount of cocatalyst was increased and the cocatalyst type was TEA. In addition, the obtained activity from butylchloride per magnesium ratio of 2.5 was similar to the usage of TEA as cocatalyst and a mole ratio per titanium of 5. The external morphology of the obtained polymers was amorphous as the catalyst morphology. However, the molecular weight and molecular weight distribution were narrower when the TEA having molar ratio per titanium of 5 was used.

title: Development and characterization of chitosan blended bacterial cellulose film

description: In order to develop a bio-degradable food packaging film combined the preservative functions of antimicrobials; the chitosan/bacterial cellulose (CBC) composite film was developed by blending the chitosan in acetic acid solution and bacterial cellulose (BC) slurry. The composite bio-films were prepared by casting method and were characterized for physical, mechanical, and antimicrobial properties. It was found that the physical and mechanical properties of CBC films were improved in comparison to those of the chitosan pure film, which was remarkably dependent on molecular weight of chitosan and the amount of BC content. The FTIR result indicated the intermolecular interaction between chitosan and BC. The crystallinity and the water absorption capacity were also enhanced with the BC content up to the weight ratio of chitosan: BC around 10:6-10:8. The CBC film exhibited the antimicrobial activity against the gram positive bacteria, Staphylococcus aureus. It was shown that the modified CBC film structure and interactions in ionic-crosslinked chitosan combined with interactions with BC fibril networks were effective for the control and limit of chitosan release from the CBC films. The modified chitosan films by blending with BC show the benefit properties for further development as food packaging material.
