Thai gas demand seen outstripping supply
Energy Technology Data Exchange (ETDEWEB)
Thailand's demand for gas will outstrip supplies in the late 1990s as rapid economic growth continues. Gas will be a cornerstone for Thai energy policy throughout the growth, although sources in neighboring countries need development. Thai gas production will rise 25% from 1992 to average 1 bcfd by 1995. Including production from new discoveries, production could rise to 1.5 bcfd by 2000, up almost 90% from the 1992 level. Increased gas flow output in the mid-1990s will be due largely to development of Gulf of Thailand fields. By 1998, production from Gulf of Thailand fields will not be enough to offset the decline in today's fields. Thailand will need to import more than 1 bcfd by 2005 in the absence of future discoveries in the country. The paper discusses new pipelines and imports.

The effects of the fluctuations of the Thai economy of the country's petroleum industry and the outlook for the future are discussed. Thailand witnessed enormous economic growth during the 1980s and the first part of the 1990s, but events since 1997 have caused it to stutter. However, the petroleum industry remains buoyant with measures to stimulate gas and oil production and moves to privatise and deregulate energy markets. Key statistics for Thailand, historical demand trends for petroleum, the impact of the 1997 Asian economic crisis, regulation of the Thai oil market, crude and condensate production levels, refinery capacity, new entrants to the refinery sector, the Thai refinery expansion programme, the product trade balance, the challenges of fuel reformulation and demand scenarios are considered.

Indoor radon concentration measurements are carried out in an area close to uraniferous fluorite veins in northern Thailand. The concentrations are found to vary from season to season, having the highest value of 154 {plus minus} 51 Bq.m{sup -3} in winter and lowest value of 50 {plus minus} 12 Bq.m{sup -3} in summer. In the rainy season the concentration is 65 {plus minus} 23 Bq.m{sup -3}. There is a large discrepancy in radon concentrations from house to house in winter. These phenomena are believed to be influenced primarily by the degree of ground moisture content and air mass movement, i.e. much lower moisture content and less air movement during the winter compared to the summer and rainy season. The annual average radon concentrations in these dwellings very from 56 to 163 Bq.m{sup -3}, having an arithmetic mean of 89 {plus minus} 22 Bq.m{sup -3}, compared to the arithmetic mean of 37 {plus minus} 7 Bq.m{sup -3} found from dwellings in the Chiang Mai ...

Risk estimates of liver cancer due to aflatoxin exposure from peanuts and peanut products
Energy Technology Data Exchange (ETDEWEB)
An assessment was undertaken of the risk of liver cancer in the USA associated with aflatoxin ingestion from peanuts. Both laboratory-animal data and epidemiological data collected from the scientific literature and several prominent mathematical extrapolation techniques were used. Risk estimates differed by a factor of greater than 1000 when the extrapolated results of three selected animal studies were analysed. Dose-response data for the male Fischer rat, the most sensitive mammalian species studied, produced an estimate of 158 cases of liver cancer per year in the USA at current levels of aflatoxin exposure. An estimate of 58 annual cases was predicted on the basis of epidemiological data of populations in Africa and Thailand.

Port-induced erosion prediction and valuation of a local recreational beach
British Library Electronic Table of Contents (United Kingdom)
This study attempts to integrate environmental economics and coastal engineering in managing port-induced coastal erosion occurring at a common beach by using Map Ta Phut port in Thailand as a case study. The existence of the port creates coastal erosion which can be considered an externality that affects local inhabitants, and a port owner and shipping companies can be seen as ?polluters??. Overlaying of aerial photographs provided strong evidence that the coastline was severely eroded after the construction of the port. Coastal engineering softwares, LITPACK and MIKE 21 PMS, were utilized to predict future shoreline positions and investigate wave patterns around the port. The port alters wave climate and the port-induced erosion is jeopardizing a local recreational beach called Nam Rin, ...

A declaration for achieving universal basic education adopted by the World Conference on Education for All in Jomtien, Thailand, as it relates to Latin America is discussed in this paper. The document then offers an examination of educational expansion in Latin America, a discussion of disproportionate educational budget cuts, and an analysis of challenges that stem from two trends: (1) the growing gap between population growth and educational expansion; and (2) low educational quality and high repetition rates. Proposals are offered for major, gradual educational reforms based on an increased level of fiscal resources, and a change in resource management responsive to economic needs. The major obstacle to implementation is argued to be the political economy of education and of adjustment. International support of local initiatives is important in achieving basic educational equity. (33 references) (LMI)

Artificial neural network modeling of physicochemical changes of shrimp during boiling
British Library Electronic Table of Contents (United Kingdom)
Frozen boiled shrimp and dried shrimp are among the high-value fishery products of Thailand. During the production of these products boiling is one of the most important steps that affects significantly the product physicochemical properties, especially the quantity and quality of proteins, which in turn affect other apparent properties perceived by consumers. The protein changes are, however, difficult to evaluate comparing to other typical physical properties of shrimp. The objective of this study was therefore to develop an artificial neural network (ANN) model to predict the protein changes of shrimp in terms of protein loss and protein denaturation as a function of the boiling conditions, namely, concentration of salt solution and boiling time, as well as a rather easily determined ch...

Radioiodination of chicken luteinizing hormone without affecting receptor binding potency
Energy Technology Data Exchange (ETDEWEB)
By improving the currently used lactoperoxidase method, we were able to obtain radioiodinated chicken luteinizing hormone (LH) that shows high specific binding and low nonspecific binding to a crude plasma membrane fraction of testicular cells of the domestic fowl and the Japanese quail, and to the ovarian granulosa cells of the Japanese quail. The change we made from the original method consisted of (1) using chicken LH for radioiodination that was not only highly purified but also retained a high receptor binding potency; (2) controlling the level of incorporation of radioiodine into chicken LH molecules by employing a short reaction time and low temperature; and (3) fractionating radioiodinated chicken LH further by gel filtration using high-performance liquid chromatography. Specific radioactivity of the final {sup 125}I-labeled chicken LH preparation was 14 microCi/micrograms. When specific binding was 12-16%, nonspecific binding was as low as 2-4% in the ...

Ozone transport from stratosphere to troposphere
International Nuclear Information System (INIS)
"7Be produced by the interaction of cosmic rays with oxygen and nitrogen, predominantly in the stratosphere, has been used to identify and measure stratospheric ozone at the ground level. Simultaneous measurements at Whiteface Mountain, New York, in July 1975 show that the maximum "7Be concentrations are accompanied by increased ozone concentrations. Peaks in "7Be concentrations occurred on July 5-6, 11-12, 16-17, 23, and 27. Ozone peaks were observed on July 7-9, 11, 18, 24, and 27. Isentropic trajectory calculations also showed that the trajectories reaching Whiteface Mountain on July 11-12, 15-16, 23, and 27 had stratospheric origin. One-day delay in ozone peaks on July 7-9, 18, and 24 is attributed to increased tropospheric ozone production. The observed relationship between "7Be and ozone is used to deduce an upper limit of 37 ppb stratospheric ozone at Whiteface Mountain during July 1975. Thus, even during midsummer months, when ...

Abstract The salts [Cnmim]2[Mo6Cl14] (mim = methylimidazolium; n = 4, 6, 12, 16, 18) have been obtained by reaction of CnmimCl with MoCl2. Thermal analysis shows the melting point decreases with increasing alkyl chain length of the cation. The imidazolium chloromolybdates(II) with n = 6-18 decompose above 340 C; [C18mim]2[Mo6Cl14] is thermally stable up to 390 C. All compounds are insensititve to the constituents of the atmosphere. Of the higher melting salts [Cnmim]2[Mo6Cl14] (n = 4, 6), high-quality single crystals could be obtained. Single-crystal X-ray structural analyses clearly show that the cluster complex anion [Mo6Cl14]2- has an electron-precise octahedral {Mo6} cluster. For [C4mim]2[Mo6Cl14], two polymorphs differing in the cation alkyl-side-chain conformation were obtained. The ...

Thailand's natural rubber economy in an international setting: an econometric investigation
Energy Technology Data Exchange (ETDEWEB)
The Thai natural rubber economy is described in the context of the world rubber market. An econometric model is estimated for 15 structural equations; it includes the Thai, US, and rest-of-the-world rubber economies. Several simulation experiments are analyzed for the period from 1984 to 1995. Impact and dynamic multipliers are reported for major endogenous variables in response to changes in US GDP, world crude oil price, Thai replanting cess tax and Thai natural rubber production. A 1%, one-time increase in the US GDP has a positive effect on the Singapore natural rubber price. A world crude oil price decline shock has a negative effect in both the short-run and the long-run. The INRO buffer stock stabilization policy as well as alternative domestic Thai policies of market intervention are analyzed. The simulation results show that buffer stock management which allows a price band of +/-20% around the price target has the most stabilized price, compared to other band widths and no ...

Thai Family Health Routines: scale development and psychometric testing.
The aims of the study were to develop and test the psychometric properties of the Thai Family Health Routines (TFHR) scale, a 70-item self-report questionnaire used to measure the health of Thai families through their routine behaviors in daily life. Development of the TFHR was based on the structural domains of Denham's Family Health Model. The TFHR scale was initially composed of 85 items and tested on 1,040 families living in the central region of Thailand. The confirmatory factor analysis, with an acceptable factor structure model, yielded 70 items aligned with six factors: self-care, safety and prevention, mental health behavior, family care, family caregiving, and illness care routines. The preliminary psychometric properties demonstrated that the TFHR scale had satisfactory internal consistency, criterion validity, and construct validity. The test results suggested that the TFHR scale has potential benefits for family and community nurses to assess Thai ...

Least cost electricity generation options based on environmental impact abatement
Energy Technology Data Exchange (ETDEWEB)
The power sector in Thailand is the largest contributor to CO{sub 2} emissions. There is high potential to mitigate CO{sub 2} emission via alternative power generating plants. Alternative plants considered in this study include nuclear plants, integrated gasification combined cycle plants, biomass-based plants and supercritical thermal power plants. The biomass-based plants considered here are fueled with four types of biomass; paddy husk, municipal solid waste (MSW), fuel wood and corncob. The methodology for the optimal expansion plan of the power generating system over the planning horizon is based on the least-cost approach. The results from the least-cost planning analyses show that the nuclear alternative has the highest potential to mitigate not only CO{sub 2} but also other airborne emissions. Moreover, the nuclear option is the most effective abatement strategy for CO{sub 2} reduction due to its negative incremental cost of CO{sub 2} reduction.
