    To elucidate the role of retinoid X receptor (RXR) in the development of imposex caused by organotin compounds in gastropod molluscs, we investigated RXR gene expression and RXR protein content in various tissues of male and female wild rock shells (Thais clavigera). Quantitative real-time polymerase chain reaction, Western blotting, and immunohistochemistry with a commercial antibody against human RXR {alpha} revealed that RXR gene expression was significantly higher in the penises of males and imposex-exhibiting females than in the penis-forming areas of normal females (P < 0.01 and P < 0.05, respectively). Western blotting demonstrated that the antibody could detect rock shell RXR and showed that the male penis had the highest content of RXR protein among the analyzed tissues of males and normal females. Immunohistochemical staining revealed nuclear localization of RXR protein in the epithelial and smooth muscle cells of the vas deferens and in the interstitial or connective tissues and epidermis of the penis in males and imposex-exhibiting females. RXR could be involved in the mechanism of induction of male-type genitalia (penis and vas deferens) by organotin compounds in female rock shells.

    Full Text Available The basic type of rock mass reinforcement method for both preparatory and operational workings in underground metal ore mines, both in Poland and in different countries across the world, is the expansion shell or adhesive-bonded rock bolt. The article discusses results of static loading test of the expansion shell rock bolts equipped with originally developed deformable component. This component consists of two profiled rock bolt washers, two disk springs, and three guide bars. The disk spring and disk washer material differs in stiffness. The construction materials ensure that at first the springs under loading are partially compressed, and then the rock bolt washer is plastically deformed. The rock bolts tested were installed in blocks simulating a rock mass with rock compressive strength of 80 MPa. The rock bolt was loaded statically until its ultimate loading capacity was exceeded. The study presents the results obtained under laboratory conditions in the test rig allowing testing of the rock bolts at their natural size, as used in underground metal ore mines. The stress-strain/displacement characteristics of the expansion shell rock bolt with the deformable component were determined experimentally. The relationships between the geometric parameters and specific strains or displacements of the bolt rod were described, and the percentage contribution of those values in total displacements, resulting from the deformation of rock bolt support components (washer, thread and the expansion shell head displacements, were estimated. The stiffness of the yielded and stiff bolts was empirically determined, including stiffness parameters of every individual part (deformable component, steel rod. There were two phases of displacement observed during the static tension of the rock bolt which differed in their intensity.

    A key issue in underground mining is to understand and master the evolving patterns of stress induced by mining, and to control and utilize the action of rock pressure. Numerical and physical modeling tests have been carried out to investigate the distribution patterns of stress in the rock surrounding a fully mechanized top-coal caving (FMTC) face. The results showed that a macro-stress shell composed of high stress exists in the rock surrounding an FMTC face. The stress of the shell is higher than its internal and external stress and the stresses at its skewback producing abutment pressure for the surrounding rock. The stress shell lies in the virgin coal and rock mass in the vicinity of the face and its sagging zone. The stress shell, which bears and transfers the loads of overlying strata, acts as the primary supporting system of forces, and is the corpus of characterizing three-dimensional and macro-rock pressure distribution of mining face. Its external and internal shape changes with the variations in the working face structure as the face advances. Within the low-stress zone inside the stress shell, another structure, i.e. voussoir beam, which only bears parts of the load from the lower-lying strata, will produce periodic pressures on the face instead of great dynamic pressure even if the beam ruptures and loses stability. The results show that the FMTC face is situated within the lower-stress zone, which is protected by the stress shell of the overlying surrounding rock. We give an explanation of lower occurrence of rock pressure on FMTC faces, and reveal the mechanical nature of the top coal of an FMTC face acting as a 'cushion'. The strata behaviors of the face and its neighboring gates are under control of the stress shell. Drastic rock pressure in mine may occur when the balance of the stress shell is destruction or the forces system of the stress shell transfers. Crown Copyright

    The distribution of surrounding rock stress in fully mechanized top-coal caving (FMTC) face was fully researched by large-scale and non-linear three-dimensional numerical simulation and equivalent laboratory. The results show that, there is the structure that is made of macroscopical stress shell composed of high stress binds in overlying strata of FMTC face. Stress shell, which bears and pass load of overlying strata, is primary supporting body. The stress in skewback of stress shell forms abutment pressure of surrounding rock in vicinity of working face. Bond-beam structure lies in reducing zone under stress shell. It only bear partial burden of strata under stress shell. The uppermost mechanical characteristic of FMTC face is lying in the low stress area under stress shell. It is the essential cause of strata behaviors of FMTC face relaxation. On the basis of analyzing stress shell, the mechanical essence that top coal performs a function of bedding is demonstrated. 4 refs., 7 figs.

    The IGNS proton microprobe has been applied in a study of the distribution of Calcium, Strontium and Fluorine in the calcite shells of Pacific Oyster (Crassostrea gigas) and the native Rock oyster (Crassostrea glomerata). The ultimate aim is to derive information which could have application in such fields as archaeology, biology, palaeontology, aquaculture and environmental studies. Calcium and strontium were determined from their emissions of K X-rays under proton bombardment, and fluorine from the 19 F (p,alpha gamma) 16 O nuclear reaction. The three elements were determined simultaneously at points no more than 20 micrometres apart. A total of 14 one and 17 two-dimensional scans were performed on sections of the shells embedded in epoxy resin. We studied shells from nine Pacific oysters (five transferred from the Marlborough Sounds to Wellington Harbour and four from the Bay of Islands). (author). 11 refs.; 5 figs

    This study aimed to assess bacterial spoilage of half shell Pacific and Sydney rock oysters during storage using microbial culture and 16S rRNA pyrosequencing. Odour and pH of oyster meats were also investigated. Estimation of microbiological counts by microbial culture highlighted growth of psychrotrophic bacteria. During storage, odour scores (a score describing deterioration of fresh odours where a score of 1 is fresh and 4 is completely spoiled) increased from 1.0 to 3.0 for Pacific oysters and from 1.3 to 3.4 for Sydney rock oysters. pH results obtained for both species fluctuated during storage (range 6.28-6.73) with an overall increase at end of storage. Pyrosequencing revealed that the majority of bacteria at Day 0 represented taxa from amongst the Proteobacteria, Tenericutes and Spirochaetes that have not been cultured and systematically described. During storage, Proteobacteria became abundant with Pseudoalteromonas and Vibrio found to be dominant in both oyster species at Day 7. Analysis of the pyrosequencing data showed significant differences in bacterial profiles between oyster species and storage time (both P = 0.001). As oysters spoiled, bacterial profiles between oyster species became more similar indicating a common spoilage profile. Data presented here provides detailed insight into the changing bacterial profile of shucked oysters during storage and has identified two genera, Pseudoalteromonas and Vibrio, as being important in spoilage of shucked oysters.

    In order to explore the influence of different caving thicknesses on the MSS dis-tribution and evolving characteristics of surrounding rocks in unsymmetrical disposal and fully mechanized top-coal caving (FMTC), based on unsymmetrical disposal characteris-tics, the analyses of numerical simulation, material simulation and in-situ observation were synthetically applied according to the geological and technical conditions of the 1151(3) working face in Xieqiao Mine. The results show that the stress peak value of the MSS-base and the ratio of MSS-body height to caving thickness are nonlinear and inversely proportional to the caving thickness. The MSS-base width, the MSS-body height, the MSS-base distance to working face wall and the rise distance of MSS-base beside coal pillar are nonlinear and directly proportional to the caving thickness. The characteristics of MSS distribution and its evolving rules of surrounding rocks and the integrated caving thickness effects are obtained. The investigations will provide lots of theoretic references to the surrounding rocks' stability control of the working face and roadway, roadway layout, gas extraction and exploitation, and efficiency of caving, etc.

    Full Text Available This paper documents a qualitative investigation on the study of instructive methods of Thai traditional singing instructors in higher education in Thailand. The information was collected in the form of document analysis and interviews with Thai traditional music instructors from several universities across Thailand. The results of the analysis of Thai traditional singing instruction methods in higher education in Thailand revealed that there are 11 universities that offer Thai traditional singing instruction. The instruction is a part of curricula under four different governing bodies and four classifications of curriculum. The sets of practicum repertoires in every university were found to be almost identical. It was found that the instructors used several techniques. Some techniques were similar while some were different. All the techniques were transmitted orally. In order to successfully produce graduates of the desired standard, singing must be correctly taught from the basics, whether theory, pronunciation or rhyming. At the same time, creativity should also be encouraged

    2014-02-01

    Shell use and partitioning of two sympatric hermit crab species (Diogenes moosai and Diogenes lopochir), as determined by shell shape, size and availability, were examined from August 2009 to March 2011 in a tropical mudflat (Malaysia). Shells of 14 gastropod species were used but > 85% comprised shells of Cerithidea cingulata, Nassarius cf. olivaceus, Nassarius jacksonianus, and Thais malayensis. Shell partitioning between hermit crab species, sexes, and developmental stages was evident from occupied shells of different species, shapes, and sizes. Extreme bias in shell use pattern by male and female of both species of hermit crabs suggests that shell shape, which depends on shell species, is the major determinant of shell use. The hermit crab must however fit well into the shell so that compatibility between crab size and shell size becomes crucial. Although shell availability possibly influenced shell use and hermit crab distribution, this is not critical in a tropical setting of high gastropod diversity and abundance.

    Demand for natural gas in Thailand is increasing significantly as the Electricity Generating Authority of Thailand and the independent private power producers (IPPs) switch from oil to gas to fire their power stations in line with Government policy to reduce oil imports and use more gas from the Gulf of Thailand. The Petroleum Authority of Thailand (PTT) has the sole right to buy and sell natural gas and other petroleum products in Thailand. According to PTT, the surge in demand for natural gas in the first half of 2001 was matched by a fall in demand for refined oil products. The PTT has received Government approval to convert to a limited company ready for listing on the Thai Stock Exchange. This is expected to further increase gas consumption. Details of gas sales to power generation and other industrial sectors by PTT and Unocal, Thailand's largest producer, are given. PTT operations include work to extend its gas pipeline transmission system. A number of new pipeline schemes are planned, including one across southern Thailand to transfer offshore gas from the Joint Development Area gas field owned by Thailand and Malaysia. This has encountered protests over the proposed plant and pipeline route

    Men's health awareness, including the research and study of quality of life, sexual desires and risk factors, has increased worldwide. In Thailand, this advancement is made possible by cooperation, research and sponsorship from the local Thai community. This article aims to illustrate the sexual attitudes of Thai people, to determine the degree of erectile dysfunction (ED) and to investigate how to manage and cope with ED in a Thai community. We reviewed the relevant literature from Thai-based articles and surveys in regard to men's health, sexual attitudes, the prevalence of ED and common risk factors in the Thai community. The primary risk factor for ED in Thai men was age-related health decline and the presence of vascular disease. Most Thai men will seek consultation from their partner in regard to ED. The main presentation of metabolic disease in Thai patients was dyslipidemia. New selective serotonin reuptake inhibitors are not available for premature ejaculation in Thai communities. The debate in regard to malpractice compensation is an issue that should be closely monitored. There is currently a shortage of home care for the elderly in Thailand. The insights provided by the articles helped recruit the study patients and in turn, helped us gain knowledge that can be translated into improved men's health care in Thailand.

    This study, based on data collected in 2005 from Chai Nat province, examines the level of happiness of the Thai elderly population and its relationship to various external and internal factors. It was found that mean happiness was slightly above a feeling of "neutral." According to multiple regression analyses, external factors including economic hardship, living arrangements, functional ability, perceived social environment, and consumerism significantly influence the level of happiness. The strongest predictor of happiness is, however, the internal factor-that is, a feeling of relative poverty when compared to their neighbors. Controlling for demographic and all external factors, the respondents who do not feel poor show the highest level of happiness compared to those who feel as poor as or poorer than their neighbors. This is self-interpreted as a feeling of contentment with what one has, which has been influenced by Thai culture, which is pervaded by Buddhism.

    This paper reports that Thailand continues to mark progress on the ambitious expansion of its petrochemical industry. Among recent developments: The outlook for Thailand's troubled worldscale aromatics project has improved with a major cut in its estimated cost. In addition, the project apparently has drawn the interest of other companies seeking a possible equity stake. Amoco Chemical Co., which lost a tender to build a worldscale purified terephathalic acid (PTA) complex in Thailand to Taiwan's Tuntex Co., is reviving its bid with a proposal similar to its earlier one. Amoco contends there will be enough demand to warrant a second PTA plant in Thailand. Tuntex is negotiating with several business groups to take part in its $333 million, 350,000 ton/year PTA project in Thailand. Tuntex is soliciting interest from a number of Thai companies, including Bangkok Bank and the Saha Union industrial conglomerate to acquire portions of the 51% interest in the project earmarked for Thai shareholders. The firm also is negotiating with a number of Japanese companies with whom it has long trade ties, including Mitsui and Co. and Marubeni Corp. to acquire part of the 49% foreign shareholding in the project. Thai Olefins Co. (TOC) marked further progress with feedstock contracts and financing arrangements for its proposed $720 million olefins plant, part of Thailand's second worldscale petrochemical complex (NPC II).

    Full Text Available Namprik is a typical Thai food containing various herbs. The diversity of Namprik depends on herb composition and content, cooking method, and flavor. The objective of this study was to develop a fine, driedand granular Namprik formula for eating with rice. The ingredients included many commonly found Thai herbs. The recipe of lemon grass Namprik produced by Satree Ban-Tung group, Khaokram district, AmphurMueang, Krabi province, Thailand, was reformulated. Mixture design was applied to optimize the amounts of black pepper (10-33%, garlic (10-66.67% and shallot (10-66.67%. Contour plot of hedonic scores andthe predictive regression models were calculated. Results showed that optimal formula should have 23.33% black pepper, 66.67% garlic and 10% shallot. Optimum levels of additional mixed herbs consisting of 5-25%kaffir lime leaves and 75-95% holy basil in the formula, using the mixture design, were also investigated. The results of sensory evaluation using 9-point hedonic scale showed no significant differences in appearance,taste and overall liking (p>0.05. However, the formula containing 4.2% kaffir lime leaves and 15.8% holy basil obtained the highest average score for aroma (p<0.05. Various amounts of dried African chili (7, 5,3% were added to determine an acceptable hot and spicy flavor, using just-about-right scale. The results revealed that the formula containing 7, 5 and 3% dried African chili were defined as just-about-right by 22, 32 and 42% of the panelists, respectively. The final product was given average hedonic scores of aroma, taste,spicy and overall liking ranging from like moderately to like very much. Appearance scores were in the range of like slightly to like moderately. This study indicated that a more nutrition and healthier Namprik containing some Thai herbs can be produced.

    2015-01-01

    The purpose of this research was to develop and test the psychometric properties of the Thai version of the Work Ability Index (WAI). Forward translation and back-translation of the WAI were performed by seven bilingual professionals to ensure that the Thai WAI was culturally relevant and conceptually accurate. To ensure generalizability of the Thai WAI, a sample of 2,744 Thai workers from 19 different enterprises in five regions of Thailand completed the Thai version of the WAI along with the General Health Questionnaire. The 19 enterprises were from the following industries: canned food, snack food, cooking oil, footwear, pharmaceutical, ceramics, toy, steel, petrochemical, and auto parts. The results from exploratory factor analysis supported a 3-factor model, accounting for 53.49% of the total variance. The results also provided evidence for adequate test-retest reliability and internal consistency of the Thai WAI. The internal consistency of the Thai WAI was found to be slightly low due to the newness of the concept of work ability, which is not a common term used in the Thai language; therefore, explanation of the meaning of work ability is needed to increase understanding of workers. By providing early recognition of workers' health risks as well as risks of early termination, the WAI can help Thai human resources managers respond better to the needs of workers and be proactive in their efforts to retain workers in their organizations. Occupational health professionals could also utilize the WAI to evaluate the work ability of Thai workers in order to help organizations recognize early signs of their workers' health risks and possible early terminations and respond appropriately.

    To assess the validity and test-retest reliability of a Thai translation of the Migraine Disability Assessment (MIDAS) Questionnaire in Thai patients with migraine. Migraineurs from the Headache Clinic in Siriraj Hospital were recruited and asked to complete a 13-weeks diary and answered the Thai-MIDAS at once. Some participants were asked to provide the 2nd Thai-MIDAS in the next 2 weeks for test-retest reliability. Ninety-three patients had completed the 13-weeks diaries. Age range was 18-58 years with mean 37.69 +/- 9.60 years. All 5 items and the total score of Thai-MIDAS were moderately correlated with data from 13-weeks diary (Spearman's correlation coefficient = 0.32-0.62). The test-retest reliability of the total score of Thai-MIDAS in 30 patients demonstrated a highly reliable degree of intraclass correlation (ICC = 0.76, 95% CI 0.49-0.88). The present study reveals that the Thai-MIDAS has satisfactory validity and reliability in comparison with the original English MIDAS version.

    To determine the validity ofthe Thai version ofthe Bergen FacebookAddiction Scale (Thai-BFAS) using Facebook addiction screening in Thai high school students. The original BFAS was authorized for translation and validation in Thai. After content validity and usability were approved by three Thai psychiatrists, the Thai-BFAS was adjusted again by the authors and back translated by an English expert. Thisfinal version was investigated using the internal consistency method among 874 high schools students in Bangkok, Chiang Mai, Ubon Ratchathani and Songkhla, and confirmatoy factor analysis (CFA) was employed to prove that the six-component model could be representative of addiction behaviors. In addition, test-retest reliability was performed separately among 30 pilot high school students in Bangkok. The Thai-BFAS has six items, which are each scored on a 5-point scale with total score ranges from 0 to 24; the cutoff score for Facebook addition stands at least 12 points. The Cronbach s alpha coefficient was 0.91 (95% CI; 0.90, 0.92) and the inter-class correlation coefficient was 0.80 (95% CI; 0.49, 0.92). The CFA showed that the six items accurately represent the six-component model of addiction such as salience, mood modification, tolerance, withdrawal, relapse and conflict. The Thai-BFAS is consistent as a screening testfor Facebook addiction among high school students due to good reliability and validity. It also conforms well to the original version. The six items in the Thai-BFAS are a good representation of the addiction behaviors. Further studies should be undertaken in cases of sensitivity and specificity when compared with other similar tests of addiction as well as in various additional populations and circumstances.

    Out-of-school youth in Thailand engage in risky sexual behavior that puts them at risk for contracting HIV infection and can have other negative sexual reproductive health outcomes. No study has examined risky sexual behaviors and compared them between Thai and non-Thai out-of-school youth. The current study compares sexual risk behavior and HIV testing behavior between out-of-school Thai and non-Thai youth. We conducted face-to-face interviews in this study population in urban Chiang Mai during 2014. Participants were recruited through convenience sampling from two main sources: non-formal education centers (NFECs) and social meeting places. We recruited 924 youth, aged 15-24 years, of whom 424 (45.9%) were Thai and 500 (54.1%) were non-Thai. The majority were attending NFECs (82.3%). Of the sexually experienced participants (57.7%), 75.4% did not use condoms consistently, and 50.3% had at least 2 lifetime sexual partners. Among the study participants, the Thai studied youth had significantly higher odds of ever having had sex (AOR=2.33; 95% CI: 1.56-3.49; p<0.001), having an earlier sexual debut (AOR=5.52; 95% CI: 2.71-11.25; p<0.001) and having a larger number of lifetime sexual partners (AOR=2.31; 95% CI: 1.37-3.88; p=0.002) than non-Thai participants. There was no significant difference between the Thai and non-Thai participants in terms of having HIV testing. The Thai studied youth were more likely to engage in risky sexual behavior than the non-Thai youth. However, both groups displayed risky sexual behaviors. Future research should explore indepth the drivers of risky sexual behaviors among both Thai and non-Thai youth.

    Childhood asthma is a substantial health burden in Thailand. Due to a lack of pediatric respiratory specialists (pediatric pulmonologists and allergists; RS), most Thai children are cared for by general pediatricians (pediatric primary care providers (PCP)). We investigated whether current practices of Thai pediatricians complied with asthma guidelines and compared practices (diagnosis and treatments) provided by PCP and RS. A cross-sectional study was conducted using electronic surveys including four case scenarios of different asthma phenotypes distributed to Thai pediatricians. Asthma diagnosis and management were evaluated for compliance with standard guidelines. The practices of PCP and RS were compared. From 800 surveys distributed, there were 405 respondents (51%). Most respondents (81%) were PCP, who preferred to use clinical diagnosis rather than laboratory investigations to diagnose asthma. For acute asthmatic attacks, 58% of the pediatricians prescribed a systemic corticosteroid. For uncontrolled asthma, 89% of the pediatricians prescribed at least one controller. For exercise-induced bronchospasm, 55% of the pediatricians chose an inhaled bronchodilator, while 38% chose a leukotriene receptor antagonist (LTRA). For virus-induced wheeze, 40% of the respondents chose an LTRA, while 15% chose inhaled corticosteroids (ICS). PCP prescribed more oral bronchodilators (31% vs. 18%, p = 0.02), antibiotics (20% vs. 6%, p attack. Most of the Thai pediatricians' practices toward diagnosis and treatment of acute asthmatic attack and uncontrolled asthma conform to the guidelines. PCP prescribed more oral bronchodilators, antibiotics, and antihistamines than RS.

    Full Text Available A number of features of business discourse in English in a Thai workplace, for example, in e-mail memos, are integral to modern business operations. In this study, a questionnaire was used to find the important situations in which English is used in business communication. For this purpose, Thai businesses were requested to provide samples of written business correspondence—mostly e-mails in English. These e-mails were examined using genre analysis to identify typical moves and steps in order to understand the use of English at the linguistic and discourse levels. Genre can be defined as a class of communicative events, with the members sharing some set of communicative purposes. Interviews were also conducted to gather data in order to describe in-depth, the nature of English language communication and possible problems arising in a Thai business context. The findings showed that despite a large number of errors in usage in the English samples, they rarely caused problems with the running of the business as Thai communicators employed a move/step structure in their e-mails and other communications strategies including follow-up inquiries for clarification. Pedagogical implications are discussed.

    Full Text Available Through history of nation building, Thai and Javanese people interacted with other language speakers. For example, they interacted with Indian mbrchants who also brought their literature and religions. In their contacts, Thai and Javanese speakers adopted Sanskrit words for enriching their own vocabularies. This article attempts to describe the meanings of Sanskrit loanwords. In comparison between the meanings of Sanskrit loanwords in Thai and Javanese languages, there are 14 categories of semantic adaptations which are found in both languages. These changes reflect the changes of the socio-cultural background of the Thai and Javanese speakers.

    2004-05-01

    This paper reports on an ethnographic study of gender and sexuality as factors within contemporary Thai factory women's subjectivities. Competing discourses of what it means to be a woman in contemporary Thai society make women's self-presentations fluid and incoherent. Data from participant-observation and open-ended interviews suggest that the fluidity and inconsistency of women's self-presentations reflect both their negative experiences and oppression within the Thai patriarchal system, and women's strength and resistance to the normative discourses that oppress them. By naming or reinterpreting experiences and desires in their own terms, Thai factory women can redraw elements of their own lives.

  9. 'Escher' Rock

    [figure removed for brevity, see original site] Chemical Changes in 'Endurance' Rocks [figure removed for brevity, see original site] Figure 1 This false-color image taken by NASA's Mars Exploration Rover Opportunity shows a rock dubbed 'Escher' on the southwestern slopes of 'Endurance Crater.' Scientists believe the rock's fractures, which divide the surface into polygons, may have been formed by one of several processes. They may have been caused by the impact that created Endurance Crater, or they might have arisen when water leftover from the rock's formation dried up. A third possibility is that much later, after the rock was formed, and after the crater was created, the rock became wet once again, then dried up and developed cracks. Opportunity has spent the last 14 sols investigating Escher, specifically the target dubbed 'Kirchner,' and other similar rocks with its scientific instruments. This image was taken on sol 208 (Aug. 24, 2004) by the rover's panoramic camera, using the 750-, 530- and 430-nanometer filters. The graph above shows that rocks located deeper into 'Endurance Crater' are chemically altered to a greater degree than rocks located higher up. This chemical alteration is believed to result from exposure to water. Specifically, the graph compares ratios of chemicals between the deep rock dubbed 'Escher,' and the more shallow rock called 'Virginia,' before (red and blue lines) and after (green line) the Mars Exploration Rover Opportunity drilled into the rocks. As the red and blue lines indicate, Escher's levels of chlorine relative to Virginia's went up, and sulfur down, before the rover dug a hole into the rocks. This implies that the surface of Escher has been chemically altered to a greater extent than the surface of Virginia. Scientists are still investigating the role water played in influencing this trend. These data were taken by the rover's alpha particle X-ray spectrometer.

    The authors examined the relationship between socioeconomic status and smoking in Thai adults. A nationally representative sample of 7858 Thais adults (18 years and older) was surveyed during 2004 to 2005. Four demographic/socioeconomic indicators were examined in logistic models: gender, education, occupational status, and annual household income. Overall, 22.2% of the participants were smokers. Men were more likely to be smokers across all age groups and regions. Compared with nonsmokers, current smokers were less educated, more likely to be employed, but had lower household income. When stratified by gender, education and job levels were strongly associated with smoking prevalence among males. A significant relationship was found between annual household income and smoking. Those who lived under the poverty line were more likely to smoke than persons who lived above the poverty line in both genders. The present study demonstrated that socioeconomic factors, especially education level and occupational class, have a strong influence on smoking behavior in Thai adults.

    Foot and ankle problems in Thai monks have not been explored. This is an unshod population, and its members have a unique lifestyle living among others in our modern era. Beginning at their ordainment, they follow strict rules about barefoot walking, the amount of daily walking, and their sitting position, practices that theoretically can increase their risk of developing foot and ankle problems. To evaluate the prevalence ofcommon foot and ankle problems in Thai monks. A cross-sectional survey was conducted in combination with foot and ankle examinations of monks living in northern Thailand Foot morphology was examined using a Harris mat footprint. Results of the interviews and the foot and ankle examinations were evaluated. Two hundred and nine monks from 28 temples were included in this study. Common foot and ankle problems found included callosity (70.8%), toe deformities (18.2%), plantar fasciitis (13.4%), metatarsalgia (3.8%), and numbness (2.9%). Callosity and toe deformities were associated with prolonged barefoot walking over extended periods since ordainment (p < 0.05). The callosity was found on the forefoot (47.3%), lateral malleolus (40.7%), and heel (12%). Arch types were considered normal in 66.4% of cases, high in 21.6%, and low in 12%. No association was found between arch type and foot and ankle problems. Callosity and toe deformity were the most common foot and ankle problems found in Thai monks, especially those with prolonged period of barefoot walking and long-term duration ofordainment. The unique pattern of walking and sitting of Thai monks may have contributed to the development of those feet and ankle problems.

    Full Text Available During the past few decades, Thai women have learned how to extent their roles from a care taker of children and a household to natural resources and environmental protection and management in local and inter-regional communities. Due to the application of National Economic and Social Development Plans, rapid resource exploitation has brought in natural resource and environmental degradation all over the country threatening communal security. For this reason, there have been a number of emerging environmental leaders who want to correct directions of national development, especially Thai woman environmental leaders who are taking a successful role of environmental guardian in their communities. This research attempts to explore why they took leadership role in environment, how they work so successful as an environmental guardian, and what their next move is. During early 2013 till mid-2014, there are 28 Thai woman leaders who received the award of Thai Environmental Conservation Mother from the Faculty of Environment and Resource Studies, Mahidol University between 2004 and 2012. They were in-depth interviewed and collected data were preceded by content analysis. Their lessons learnt show that most leaders saved their communities' environment and natural resources from the intervention of new development activities. Most of them had their parents as a good role model in environmental management who provide knowledge of morals and environmental ethics as a good basic of leadership while some shared their husband's responsibility in the same matter. Significantly, teamwork is their working style with the assistance of public participation to hold teamwork and collaboration of the community. Almost all leaders had systematic working with talents of patience, gentleness and sensitivity. The working network also broadens their new information and knowledge between practitioners. In the same time, more than half of the leaders can prepare their

    Preservatives are added to cosmetics and other consumer products to prevent microbial growth and product degradation. Many cosmetic preservatives are skin sensitizers and frequent causes of contact dermatitis. The use of preservatives may vary by country and/or region, according to legislation, and may be reflected in differences in the prevalence rates of preservative allergy worldwide. To examine the type and frequency of preservative use in cosmetics sold in Thai markets in metropolitan Bangkok, Thailand. Preservatives contained in 1000 different cosmetics sold in Thai markets were documented and analysed, based on the labelling of ingredients. Most of the cosmetic and skincare products sold in Thai markets were international brands, with only a small proportion of cosmetic products being produced in Thailand. International brand cosmetics were more likely to contain non-formaldehyde-releasing preservatives than domestically produced brands. Isothiazolinone-based preservatives, which are responsible for the current increase in the prevalence of contact allergy, were found at a significant frequency in domestically produced, leave-on cosmetic products. Preservatives in cosmetics were significantly different according to source of production and type of cosmetics. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Ever since Chuck Berry coined the term “rocking pneumonia” in his 1956 song “Roll over Beethoven”, pneumonia has been mentioned frequently in modern blues and rock songs. We analyzed the lyrics of these songs to examine how various elements of pneumonia have been represented in popular music, specifically the cause of pneumonia, the risk groups, comorbidity (such as the boogie woogie flu), the clinical symptoms, and treatment and outcome. Up to this day, songwriters suggest that pneumonia is ...

    Pedagogical Content Knowledge (PCK) was accepted by worldwide Educators that it is a ubiquitous word in the preparation of teachers in the past decade. This study uses Pedagogical Content Knowledge (PCK) framework as a lens for classifying the guidelines and expectations for categorizing expertise teachers. Therefore, the paper tries to clarify the relationship between competencies of Thai expertise teacher and PCK elements. To promote skillful Thai teachers by offering them academic titles, the Office of the Teacher Civil Service and Education Personal Commission were developed to provide guidelines and expectations for categorizing expertise teachers (OTEPC, 2009). This article focuses on the guideline criteria which are three areas of consideration. The first area of consideration is teacher's disciplines including virtues and professional conducts. The second area of consideration is teacher's knowledge and teaching ability. The last area of consider is teacher's performance. It seemed that the OTEPC guideline pay too much attention on the first area. However, there are some issues of PCK appearing on the OTEPC teacher competency. The paper will discuss some suggestions of fill up PCK in the OTEPC guideline. The paper may have implication for Thailand teacher education.

    In recent years, Thai indigenous chickens have increasingly been bred as an alternative in Thailand poultry market. Due to their popularity, there is a clear need to improve the underlying quality and productivity of these chickens. Studying chicken genetic variation can improve the chicken meat quality as well as conserving rare chicken species. To begin with, a minimal set of molecular markers that can characterize the Thai indigenous chicken breeds is required. Using AFLP-PCR, 30 single nucleotide polymorphisms (SNPs) from Thai indigenous chickens were obtained by DNA sequencing. From these SNPs, we genotyped 465 chickens from 7 chicken breeds, comprising four Thai indigenous chicken breeds--Pradhuhangdum (PD), Luenghangkhao (LK), Dang (DA) and Chee (CH), one wild chicken--the red jungle fowls (RJF), and two commercial chicken breeds--the brown egg layer (BL) and commercial broiler (CB). The chicken genotypes reveal unique genetic structures of the four Thai indigenous chicken breeds. The average expected heterozygosities of PD=0.341, LK=0.357, DA=0.349 and CH=0.373, while the references RJF= 0.327, CB=0.324 and BL= 0.285. The F(ST) values among Thai indigenous chicken breeds vary from 0.051 to 0.096. The F(ST) values between the pairs of Thai indigenous chickens and RJF vary from 0.083 to 0.105 and the FST values between the Thai indigenous chickens and the two commercial chicken breeds vary from 0.116 to 0.221. A neighbour-joining tree of all individual chickens showed that the Thai indigenous chickens were clustered into four groups which were closely related to the wild RJF but far from the commercial breeds. Such commercial breeds were split into two closely groups. Using genetic admixture analysis, we observed that the Thai indigenous chicken breeds are likely to share common ancestors with the RJF, while both commercial chicken breeds share the same admixture pattern. These results indicated that the Thai indigenous chicken breeds may descend from the

    We report the differences in light stable isotopes between two kinds of Thai rice (Thai jasmine and Sungyod rice). Thai jasmine rice and Sungyod rice were cultivated in the northeast and the south of Thailand. Light isotopes including 13C, 15N and 18O of Thai jasmine rice and Sungyod rice samples were carried out using isotope ratio mass spectrometry (IRMS). Thai jasmine rice (Khao Dawk Mali 105) was cultivated from Thung Kula Rong Hai area, whereas Sungyod rice was cultivated from Phathalung province. Hypothesis testing of difference of each isotope between Thai jasmine rice and Sungyod rice was also studied. The study was the feasibility test whether the light stable isotopes can be the variables to identify Thai jasmine rice and Sungyod rice. The result shows that there was difference in the isotope patterns of Thai jasmine rice and Sungyod rice. Our results may provide the useful information in term of stable isotope profiles of Thai rice.

    Full Text Available West Beni Suef Concession is located at the western part of Beni Suef Basin which is a relatively under-explored basin and lies about 150 km south of Cairo. The major goal of this study is to evaluate the source rock by using different techniques as Rock-Eval pyrolysis, Vitrinite reflectance (%Ro, and well log data of some Cretaceous sequences including Abu Roash (E, F and G members, Kharita and Betty formations. The BasinMod 1D program is used in this study to construct the burial history and calculate the levels of thermal maturity of the Fayoum-1X well based on calibration of measured %Ro and Tmax against calculated %Ro model. The calculated Total Organic Carbon (TOC content from well log data compared with the measured TOC from the Rock-Eval pyrolysis in Fayoum-1X well is shown to match against the shale source rock but gives high values against the limestone source rock. For that, a new model is derived from well log data to calculate accurately the TOC content against the limestone source rock in the study area. The organic matter existing in Abu Roash (F member is fair to excellent and capable of generating a significant amount of hydrocarbons (oil prone produced from (mixed type I/II kerogen. The generation potential of kerogen in Abu Roash (E and G members and Betty formations is ranging from poor to fair, and generating hydrocarbons of oil and gas prone (mixed type II/III kerogen. Eventually, kerogen (type III of Kharita Formation has poor to very good generation potential and mainly produces gas. Thermal maturation of the measured %Ro, calculated %Ro model, Tmax and Production index (PI indicates that Abu Roash (F member exciting in the onset of oil generation, whereas Abu Roash (E and G members, Kharita and Betty formations entered the peak of oil generation.

    Muay Thai kickboxing is a common sport that uses the foot and ankle in fighting. Muay Thai kickboxing trainees usually receive training in Thailand Foot and ankle problems in this group ofpeople who usually train barefoot remain unexplored To evaluate the prevalence of common foot and ankle problems in Muay Thai kick boxers. The present study is a cross-sectional survey of Muay Thai kick boxers practicing in northern Thailand. Interviews were conducted and foot and ankle examinations were evaluated Foot morphology was examined using a Harris mat footprint. One hundred and twenty-three Muay Thai kickbox ersinnine training gyms were included in this study. Common foot and ankle problems found in the Muay Thai kick boxers were callosity (59%), gastrocnemius contracture (57%), toe deformities (49.3%), wounds (10%) and heel pain (9%). Callosity was most commonly found on the forefoot (77.5%), on the plantar first metatarsal (55.3%) and on the big toe (33.3%). An association was found between a tight heel cord and a history of foot injury with prolonged periods of weekly training. Toe deformities such as hallux rigidus (37.6%) were also associated with prolonged periods of training (p = 0.001). No correlation was found between type of foot arch and foot and ankle problems. Plantar forefoot callosities and wounds as well as toe deformities including tight heel cords are some of the foot and ankle problems commonly found in Muay Thai kick boxers. They are associated with prolonged periods of barefoot training. The unique pattern of training and of the kicks in Muay Thai might be a path mechanism, leading to the development of foot and ankle problems.

    Full Text Available Thai people like to cover sacred objects or things dear to them with gold leaf.. Statues of Buddha are sometimes covered with so many layers of gold leaf that they become formless figures, that can hardly be recognized. Portraits of beloved ancestors, statues of elephants and grave tombs are often covered with gold leaf. If one considers the number of Thai people and the popularity of the habit, the amount of gold involved could be considerable.

    This paper aimed to demonstrate the research and development of a rule-based expert system for skin problem consulting in the areas of acne, melasma, freckle, wrinkle, and uneven skin tone, with recommended treatments from Thai traditional medicine knowledge. The tool selected for developing the expert system is a software program written in the PHP language. MySQL database is used to work together with PHP for building database of the expert system. The system is web-based and can be reached from anywhere with Internet access. The developed expert system gave recommendations on the skin problem treatment with Thai herbal recipes and Thai herbal cosmetics based on 416 rules derived from primary and secondary sources. The system had been tested by 50 users consisting of dermatologists, Thai traditional medicine doctors, and general users. The developed system was considered good for learning and consultation. The present work showed how such a scattered body of traditional knowledge as Thai traditional medicine and herbal recipes could be collected, organised and made accessible to users and interested parties. The expert system developed herein should contribute in a meaningful way towards preserving the knowledge and helping promote the use of Thai traditional medicine as a practical alternative medicine for the treatment of illnesses.

  16. Regulation and competition issues in Thai electricity sector

    This paper explores the issues related to regulatory reform and liberalisation leading toward competition in the Thai electricity sector, which is still under the monopoly control of state-owned enterprises (SOEs). Following an overview of the current market structure of the Thai electricity sector, the process of liberalisation and deregulation that contributes to the uncompetitive market structure under SOEs’ control is examined. The author asserts that there are problems within the Energy Commission and the Energy Industry Act BE 2550 (2007) that contribute to the continuance of an uncompetitive electricity supply. Possible reforms to the Thai electricity regulation are proposed with the aim of creating market competition and efficiency in the Thai electricity sector. - Highlights: ► Author studies on the regulatory reform and a development of liberalisation plans on Thai electricity sector. ► The paper presents that the liberalisation plan was affected by the government implementation on electricity corporatisation. ► The paper asserts that the current energy regulation will not lead to market reform and competition in electricity. ► The paper also discusses on the current monopoly structure of Thai electricity sector under state owned enterprises. ► The paper concludes that Thailand needs an appropriate regulatory reform for building competition in electricity sector.

    This study investigated the presence of antinuclear antibody (ANA) in older Thais compared with middle-age and younger participants. Antinuclear antibody represents the first step in the diagnostic testing for lupus erythematosus (LE) and other autoimmune diseases. Due to the lack of reference ANA levels in older, middle-age and younger Thais healthy participants, this study will be useful for determining the proper diagnostic and treatment criteria. There were 28 older (60-76 years), 17 middle-age (41-59 years) and 13 younger (24-40 years) participants in this study. Immunofluorescence was performed to analyse the ANA staining pattern and titre levels in the participants' blood samples. The presence of serum ANA was found in 18 of 28 cases (64.3%), four of 17 (23.5%) and one of 13 cases (7.7%) of the older, middle-age and younger participants, respectively. The difference in the number of serum ANA-positive participants between the older, middle-age and younger groups was statistically significant (p < 0.05). Interestingly, the ANA positive in older participants presented more than one staining pattern. The speckled pattern was the most commonly detected ANA staining pattern in the older group, being found in 12 cases followed by cytoplasmic pattern (10 cases), homogeneous pattern (nine cases) and nucleolar pattern (five cases). In the middle-age group, the speckled pattern was found in four cases, whereas one younger participant presented a nucleolar pattern. Serum ANA positive was significantly higher in the older group compared with the middle-age and younger groups. There were variations of the serum ANA staining patterns in the older group. © 2016 John Wiley & Sons A/S and The Gerodontology Association. Published by John Wiley & Sons Ltd.

  19. Igneous Rocks

    Science.gov (United States)

    Doe, Bruce R.

    “Igneous Rocks was written for undergraduate geology majors who have had a year of college-level chemistry and a course in mineralogy … and for beginning graduate students. Geologists working in industry, government, or academia should find this text useful as a guide to the technical literature up to 1981 and as an overview of topics with which they have not worked but which may have unanticipated pertinence to their own projects.” So starts the preface to this textbook.As one who works part time in research on igneous rocks, especially as they relate to mineral deposits, I have been looking for such a book with this avowed purpose in a field that has a choking richness of evolving terminology and a bewildering volume of interdisciplinary literature. In addition to the standard topics of igneous petrology, the book contains a chapter on the role of igneous activity in the genesis of mineral deposits, its value to geothermal energy, and the potential of igneous rocks as an environment for nuclear waste disposal. These topics are presented rather apologetically in the preface, but the author is to be applauded for including this chapter. The apology shows just how new these interests are to petrology. Recognition is finally coming that, for example, mineral deposits are not “sports of nature,” a view held even by many economic geologists as recently as the early 1960's; instead they are perfectly ordinary geochemical features formed by perfectly ordinary geologic processes. In fact, the mineral deposits and their attendant alteration zones probably have as much to tell us about igneous rocks as the igneous rocks have to tell us about mineral deposits.

  20. A cross-sectional examination of growth indicators from Thai adolescent girls: evidence of obesity among Thai youth?

    Few studies have examined growth data from adolescent girls in Southeast Asia and almost none have been carried out in Thailand. Thus this study examines growth data from Thai adolescent girls. Cross-sectional growth data from a sample of Thai girls were compared to reference data from healthy well-nourished girls. It is hypothesized that the reference girls will be taller and heavier than the Thai girls; however, the growth indicators will also indicate that obesity is present among Thai girls. Anthropometric and age at menarche data were collected from a sample of 319 adolescent girls ages 11-17 years living in suburban Thailand. Thai girls are heavier than the reference girls at ages 11-13 years yet are shorter and lighter than the reference girls at ages 14-17 years. The data also reveal that 18.4% of the girls are overweight or obese as classified by the CDC BMI-for-age percentile growth curves. The findings suggest the presence of overweight and obesity among this adolescent Thai population. These data may reflect the impact of the improved economic situation of Thailand as well as the impact of body image concerns among these young girls.

  1. White Rock

    Science.gov (United States)

    2002-01-01

    (Released 19 April 2002) The Science 'White Rock' is the unofficial name for this unusual landform which was first observed during the Mariner 9 mission in the early 1970's. As later analysis of additional data sets would show, White Rock is neither white nor dense rock. Its apparent brightness arises from the fact that the material surrounding it is so dark. Images from the Mars Global Surveyor MOC camera revealed dark sand dunes surrounding White Rock and on the floor of the troughs within it. Some of these dunes are just apparent in the THEMIS image. Although there was speculation that the material composing White Rock could be salts from an ancient dry lakebed, spectral data from the MGS TES instrument did not support this claim. Instead, the White Rock deposit may be the erosional remnant of a previously more continuous occurrence of air fall sediments, either volcanic ash or windblown dust. The THEMIS image offers new evidence for the idea that the original deposit covered a larger area. Approximately 10 kilometers to the southeast of the main deposit are some tiny knobs of similarly bright material preserved on the floor of a small crater. Given that the eolian erosion of the main White Rock deposit has produced isolated knobs at its edges, it is reasonable to suspect that the more distant outliers are the remnants of a once continuous deposit that stretched at least to this location. The fact that so little remains of the larger deposit suggests that the material is very easily eroded and simply blows away. The Story Fingers of hard, white rock seem to jut out like icy daggers across a moody Martian surface, but appearances can be deceiving. These bright, jagged features are neither white, nor icy, nor even hard and rocky! So what are they, and why are they so different from the surrounding terrain? Scientists know that you can't always trust what your eyes see alone. You have to use other kinds of science instruments to measure things that our eyes can

    Since anesthesia, unlike medical or surgical specialties, does not constitute treatment, The Royal College of Anesthesiologists of Thailand host the Thai Anesthesia Incidents Study (THAI Study) of anesthetic outcomes to determine factors related to anesthesia related adverse events. A prospective descriptive study of occurrence screening was conducted in 20 hospitals comprised of 7 university, 4 general and 4 district hospitals across Thailand. Anesthesia personnels were required to fill up patient-related, surgical-related, anesthesia-related variables and adverse outcomes on a strutured data entry form. The data included preanesthetic evaluation intraoperative period and 24 hr postoperative period. Adverse events specific form was recorded when adverse events occurred. All data were keyed in data management unit with double entry technique and descriptive statistics was used in the first phase of this study. A total of 163403 consecutive cases were recorded in one year. The mean (S.D.) of age, weight and height of patients were 38.6(2.3) yrs, 53.9(17.7) kgs and 153.4(22.7) cm respectively. There were more female (52.9%) than male (47. 1%) patients with ASA PS 1, 2, 3, 4, 5 = 50.8%, 36.3%, 10.7%, 2.0%, 0.2% respectively. Hypertension (11.6%), anemia (7.7%) and diabetes melitus (6.8%) were the three most common abnormalities in preanesthetic history taking. Mallampati score of 111870 patients grade 1, 2, 3, 4 were 54.0%, 39.7%, 5.6%, 0.7% and laryngoscopic grade 1, 2, 3, 4 of 74888 patients were 81.0%, 15.5%, 3.0% and 0.5% respectively. The first phase of THAI study epidemiological project can represent both the anesthesia and surgical profiles in Thailand. The collected data available should be useful for the improvement of the quality of anesthesia, guidelines for clinical practices, medical education and for further research.

    On the research and development project 'Rock Stress Measurements' the BGR has developed and tested several test devices and methods at GTS for use in boreholes at a depth of 200 m and has carried out rock mechanical and engineering geological investigations for the evaluation and interpretation of the stress measurements. The first time a computer for data processing was installed in the borehole together with the BGR-probe. Laboratory tests on hollow cylinders were made to study the stress-deformation behavior. To validate and to interprete the measurement results some test methods were modelled using the finite-element method. The dilatometer-tests yielded high values of Young's modulus, whereas laboratory tests showed lower values with a distinct deformation anisotropy. Stress measurements with the BGR-probe yielded horizontal stresses being higher than the theoretical overburden pressure and vertical stresses which agree well with the theoretical overburden pressure. These results are comparable to the results of the hydraulic fracturing tests, whereas stresses obtained with CSIR-triaxial cells are generally lower. The detailed geological mapping of the borehole indicated relationships between stress and geology. With regard to borehole depth different zones of rock structure joint frequency, joint orientation, and orientation of microfissures as well as stress magnitude, stress direction, and degree of deformation anisotropy could be distinguished.

    This study explored the lived experiences of Thai women in relation to alcohol addiction in treatment. Twelve women aged 20 to 65 years, were participated. The participants were recruited from two special hospitals and one outpatient clinic in a general hospital. Descriptive phenomenology was applied to analyze the transcripts of the individual interviews. The explored phenomenon of Thai women experiencing alcohol addiction included four essential aspects, (1) feeling inferior and worthless (2) feeling physically and emotionally hurt, (3) fearing physical deterioration and premature death, and (4) feeling superior and powerful. Through these different aspects of Thai women's lived experiences, the following essence was synthesized. The essence of the lived experience of alcohol addiction among the studied Thai women was ambivalence between feeling inferior and worthless and feeling superior and powerful when acting as a man. Drinking alcohol lessened life's difficulties and fears; for example, of violence, bodily demolition, premature death and marginalization from family and society. Thai women who experience alcohol addiction are treated with gender-related double standards when trying to undo gender traditional roles. Their marginalization from family and society deepens making them even more vulnerable to the positive side effects of alcohol drinking. Copyright © 2017. Published by Elsevier B.V.

  6. Thai Electoral Campaigning: Vote-Canvassing Networks and Hybrid Voting

    Directory of Open Access Journals (Sweden)

    Anyarat Chattharakul

    2010-01-01

    Full Text Available Based on evidence gathered through participant observation, this article illuminates the nature of vote-canvassing, previously a black box in Thai electoral studies. Offering a close-up study of the internal mechanisms of an individual Thai election campaign, this article reveals that vote-canvasser networks are underpinned by long-term dyadic relationships, both hierarchical and horizontal, between the candidate, vote-canvassers and voters. These networks continue to be the most important factor in winning elections. This article documents how candidates draw up an election campaign map and identify voters along residential lines to maximise their vote-canvassing strategy. The findings of this article challenge Anek’s 1996 concept of “two democracies”, which argues that rural voters are influenced by money, local leaders, political factions and corrupt politicians while more well-educated, urban, middle-class voters are more oriented toward the alternative policies offered by competing parties. The case study of Kom’s election campaign showed that the role of the much-vaunted middle-class voters is not decisive, even in suburban areas of Bangkok. While political marketing has grown in importance in Thai elections, it has not displaced traditional electoral practices. Thai society is, in fact, deeply fragmented and diverse – too complex to be divided in such a simplistic manner. This article suggests that rather than undergoing a linear transformation, political hybridisation is a key trend in Thai election campaigns.

    To explore the way Thai patients perceive and manage their diabetes. Using a focused ethnographic approach, face-to-face interviews were conducted at two public hospitals in Bangkok. All interviews (n=27) were audio-taped and transcribed verbatim. Analysis of the interview transcripts was completed thematically. The findings showed that Thai patients manage their diabetes according to their beliefs about diabetes. These beliefs are constructed using both modern and traditional knowledge. For example, some patients explained the cause of their illness as being due to biomedical factors such as genetics, and also cultural factors such as karma from either previous or current lifetimes. The analysis also revealed that some aspects of Thai life facilitate diabetes self-management while other aspects hamper good control of the illness. For example, Buddhist values of moderation contribute positively to dietary change, while, on the other hand, the importance of rice in the Thai diet can impede successful self-management strategies. The results of this research indicate that Thai culture influences diabetes perceptions and management. Culturally appropriate treatment guidelines should be established for diabetes management that give special consideration to the significance and meaning of food and to Buddhist beliefs.

    Full Text Available Pengelaman sastra Melayu di Patani Selatan Thai di bawah pemerintahan yang bukan Melayu terjadi lebih dari 100 tahun lamanya. Dasar Siamisasi yang pelopori oleh Phibul Songkram dalam menyatukan seluruh bangsa jajahannya dengan dasar 1 Siam, 1 bahasa dan 1 budaya telah membunuh kekayaan seni budaya dan keindahan kesusasteraan Melayu. Namun kesusasteraan Melayu sangat penting bagi bangsa Melayu Patani kerana bahasa dan sastra merupakan jati diri dan identitas bangsa Melayu Islam di Patani. Masyarakat Patani sendiri tidak membedakan antara bahasa dan sastra. Apabila bicara tentang sastra di Patani secara tidak langsung akan membicarakan tentang bahasa Melayu. Dalam setiap upacara dan acara baik keagamaan maupun perkawinan, sastra menjadi menu wajib baik di tingkat rendah maupun di tingkat yang besar. Sastra tidak dapat dipisahkan dari hidup masyarakat Melayu di Patani sehingga sastra merupakan sebahagian keyakinan dan kehidupan orang Melayu Patani. Walaupun orang-orang Melayu Patani sudah kehilangan negeri yang berkerajaan dan mengamalkan Melayu tetapi orang Patani masih teguh dengan bahasa dan kesusastraan Melayu.

    Antioxidants have been used as radioprotectors in cosmetics and radiation therapy to protect normal tissues in cancer patients. The objective of this study is to determine the activities of antioxidants in Thai edible plants (holy basil, sesame (white and black). durian (Chanee and Monthong), parsley, morning glory, guava, chilies, pepper, sweet pepper, ash pumpkin, pumpkin, tomato, peppermint, and sweet basil) by using I, I-diphenyl-2-picryl-hydrazyl radical and to determine their capability to inhibit radiation-induced hemolysis. Gamma rays (10 KGy) from cobalt-60 was used to induce hemolysis of human red blood cells, and ascorbic acid was used as standard antioxidant. The extracts from all samples showed antioxidant activities. However, only the extracts (0.1-1,000 μg/8 x 10 9 red blood cells) from parsley, guava, peppermint, and sweet basil could significantly inhibit (p<0.05) radiation-induced hemolysis. Although ascorbic acid is a strong antioxidant, its ability to inhibit radiation-induced hemolysis was lower than the extracts. This maybe due to its hydrophilic property which limits its ability to penetrate cell membrane

    This study explored the perceptions of 18 people diagnosed with schizophrenia from 1-10 years to uncover how they perceived themselves and their illness. It also involved 12 family members who added their perceptions. The data were collected using in-depth interviews, reflective journaling, and observations. The data were analyzed through the lens of Heidegger's hermeneutic phenomenology. Four themes emerged: perceptions of mental illness, perceptions of the causes of illness, perceptions of discrimination, and attempting to live with schizophrenia. The findings included strong underlying cultural and spiritual beliefs, and attitudes unique to the Thai participants, including the causation of schizophrenia by supernatural powers, black magic, and bad karma stemming from past deeds. Understanding the perceptions of the participants might help health-care providers to be more sensitive to those living with schizophrenia in Thailand and elsewhere. In particular, the findings could be useful in informing psychiatric careproviders about developing better caring systems for clients diagnosed with schizophrenia. This should help the sufferers of schizophrenia to live their lives to their own satisfaction and as normally as possible.

    2009-12-01

    Full Text Available Moisture sorption study was conducted on Thai red curry powder prepared by two different drying methods, viz. microwave and hot-air drying. Moisture sorption isotherms of the red curry powder at 30 C and water activity in the range of 0.113-0.970 were determined by a static gravimetric method. The isotherms exhibited Type III behaviour. The moisture sorption data were fitted to several sorption models and a non-linear regression analysis method was used to evaluate the constants of the sorption equations. The fit was evaluated using the coefficient of determination (R2, the reduced chi-square (2 and the root mean square error (RMSE. The GAB model followed by the Lewiski-3 model gave the best fit to the experimental data. The monolayer moisture content, taken as the safe minimum moisture level in the red curry powder, was determined using the BET equation and was found to range between 0.080 - 0.085 gram water per gram dry matter.

    Full Text Available This research aims at studying an elderly employment model for the Thai automotive industry. Mixed methods with a sequential exploratory strategy were utilized. Grounded theory was employed by using in-depth interviews to investigate the characteristics of elderly employment in the Thai automotive industry. For this stage of the research, theoretical and purposive sampling was used to select 32 key informants from four groups of stakeholders: (1 elderly workers, (2 employers or human resource managers, (3 government officers, and (4 academics. The findings were then validated using a quantitative approach with structural equation modelling (SEM. A total of 308 elderly workers and human resource managers were surveyed regarding their opinion about elderly employment. Based on the survey, the elderly employment model in the Thai automotive industry, which is comprised of the approach to elderly employment, elderly employment preparation, and key success factors for elderly employment, was revealed to be a good fit.

    2015-01-01

    Full Text Available In this study, a mechanical model was developed, aiming to provide standardized and programmable traditional Thai massage (TTM therapy to patients. The TTM was modeled and integrated into a mechanical hand (MH system, and a prototype massage chair was built and tested for user satisfaction. Three fundamental principles of Thai massage were integrated: pull, press, and pin. Based on these principles, the mechanics of Thai massage was studied and a mathematical model was developed to describe the dynamics and conditions for the design and prototyping of an MH. On average, it was found that users were satisfied with the treatment and felt that the treatment was similar to that performed by human hands. According to the interview results, users indicated that they were likely to utilize the MH as an alternative to traditional massage. Therefore, integrated TTM with an MH may help healthcare providers deliver standardized, programmable massage therapy to patients as opposed to variable, inconsistent human massage.

  16. Perception of injury risk among amateur Muay Thai fighters.

    Science.gov (United States)

    Strotmeyer, Stephen; Lystad, Reidar P

    2017-12-01

    Muay Thai is a style of kickboxing that allows full-contact blows to an unprotected head, torso and legs, and, as in any combat sport, there is an inherent risk of injury. Previous observational studies have shown there is a substantial risk of injury in competitive kickboxing. None of these studies, however, have investigated the potential role of psychological risk factors and, consequently, little is known about the perception of injury risk among these athletes. Notwithstanding the important role risk perception may play in the occurrence and prevention of sports injuries, there is very limited empirical data pertaining to athletes in full-contact combat sports such as Muay Thai. Because the development and successful implementation of effective injury prevention policies for combat sports are likely to benefit from an increased understanding of the perception of injury risk and sport safety attitudes and behavior of its participants, further study is warranted. Muay Thai fighters were invited to complete an online survey in which they rated the perceived risk of injury in a range of different sports, including Muay Thai kickboxing. Perceived comparative risk was obtained indirectly by subtracting perceived risk of injury to oneself from perceived risk of injury to a peer. Data were analyzed using descriptive statistics, comparison of means, and ordinal logistic regression. Contrary to the best available epidemiological evidence, Muay Thai fighters perceived the risk of injury in their own sport to be average and significantly lower than that in other collision and contact sports, including popular combat sports such as boxing and mixed martial arts. On average, Muay Thai fighters perceived their own risk injury to be significantly lower compared to their peers (p injury risk perception and actual risk among Muay Thai fighters. Moreover, these athletes also exhibit a slight degree comparative optimism or unrealistic optimism. Because behavior is determined by

    1995-01-01

    The study assesses the groundwater geochemistry and geological environment of 44 study sites for radioactive waste disposal. Initially, the study sites were divided by rock type into 5 groups: (1) acid - intermediate rocks, (2) mafic - ultramafic rocks, (3) gabbros, amphibolites and gneisses that contain calc-silicate (skarn) rocks, (4) carbonates and (5) sandstones. Separate assessments are made of acid - intermediate plutonic rocks and of a subgroup that comprises migmatites, granite and mica gneiss. These all belong to the group of acid - intermediate rocks. Within the mafic -ultramafic rock group, a subgroup that comprises mafic - ultramafic plutonic rocks, serpentinites, mafic - ultramafic volcanic rocks and volcanic - sedimentary schists is also evaluated separately. Bedrock groundwaters are classified by their concentration of total dissolved solids as fresh, brackish, saline, strongly saline and brine-class groundwaters. (75 refs., 24 figs., 3 tabs.)

    Full Text Available The Thai Bangkaew dog is a Spitz-type dog that originated in Thailand. Legend has it that the dog is descended from hybrids between a native female dog and a male wild canid. To examine the mysterious story about the ancestry of the Thai Bangkaew dog's paternal lineage, sequence variation was examined for the last intron of the Y-chromosome-specific zinc-finger gene, ZFY, and its X homolog for male Thai Bangkaew dogs and other male Thai canids, including the Thai ridgeback and mixed breed dogs, Asiatic jackals (Canis aureus and a dhole (Cuon alpinus. A 1075-bp ZFY segment from DNA samples of Thai Bangkaew dogs was found to be 100% identical to the domestic dog ZFY and (if gaps are allowed showed 81% and 92% identity to jackal ZFY and dhole ZFY, respectively. However, if gaps were treated as missing data, the 1045-bp ZFY sequence for the Thai Bangkaew dogs was 100% identical to domestic dog ZFY and 99.5% to jackal ZFY and dhole ZFY, respectively. In addition, the 959-bp Thai Bangkaew ZFX fragments were identical and showed 100% identity to domestic dog ZFX. These genetic data suggest that the Thai Bangkaew dogs still present today share a common male ancestor with modern dogs, rather than being the descendants of dhole or jackal/dog hybrids.

    Full Text Available The aim of this study was to investigate prevalence and related factors of androgen receptor (AR expression in Thai breast cancer patients. A descriptive study was done in 95 patients, who were admitted to Charoenkrung Pracharak Hospital, Bangkok (2011–2013. Statistical relationships were examined between AR protein expression, tumor status, and patient characteristics. Compared with those from Western countries, ethnic Thai patients were younger at age of diagnosis and had a higher proliferative index (high Ki-67 expression, which indicates unfavorable prognosis. In addition, 91% of the Thai breast tumors that were positive for any of the following receptors, estrogen receptor (ER, progesterone receptor (PR, and human epidermal growth factor receptor 2 (HER2 also expressed the AR protein, while in triple negative breast tumors only 33% were AR positive. ER and PR expression was positively related with AR expression, while AR expression was inversely correlated to Ki-67 expression. AR status was strongly correlated with ER and PR status in Thai patients. There is an inverse relationship between Ki-67 and AR, which suggests that AR may be a prognostic factor for breast cancer.

    2017-01-01

    Full Text Available Objective: To determine the prevalence, and associated factors of atypical eating attitudes and behaviors in Thai medical students. Methods: A cross-sectional survey examined the eating abnormalities in Thai medical students, conducted in 2014. Research assistants collected data by using; self-reported questionnaires using The Eating Attitudes Test-26 (EAT-26 Thai Version. The statistical analysis used R-program for qualitative variables and logistic regression was applied to determine the correlation and P-value. Results: 141 Thai, medical students (15.9% were reported to have atypical attitudes towards eating, and displayed abnormal eating behaviors. There was no statistically significant correlation of attitude towards eating, and their current eating behaviors according to the medical students’ gender, year of studying and Grade Point Average. However, their eating attitudes and behaviors were, associated with Body Mass index. Normal weight (BMI 18.5- 23.49 and overweight (BMI 23.5-39.9 groups could increase by 2.2 (95% CI =1.2, 4.3 and 2.3 (95% CI=1.1, 4.8 times risk depending on atypical eating attitudes and abnormal eating behaviors respectively, when compared with the underweight group (BMI<18.5. Conclusion: There was no correlated difference in concerns to the Thai medical student’s abnormal eating habits, with gender, years of their study and Grade Point Average. Only normal to over-weight BMI were associated. Overweight male, medical students significantly represented more atypical attitudes towards eating and behaviors than other groups in this population. These results may reveal the changing trends of eating attitudes and behaviors due to the current ideal body image of being more muscular. However, prospective studies are still needed.

    Wang, Hongbin; Feng, Yinhan; Cheng, Liang

    2018-03-01

    Sentence similarity computation plays an increasingly important role in text mining, Web page retrieval, machine translation, speech recognition and question answering systems. Thai language as a kind of resources scarce language, it is not like Chinese language with HowNet and CiLin resources. So the Thai sentence similarity research faces some challenges. In order to solve this problem of the Thai language sentence similarity computation. This paper proposes a novel method to compute the similarity of Thai language sentence based on syntactic structure and semantic vector. This method firstly uses the Part-of-Speech (POS) dependency to calculate two sentences syntactic structure similarity, and then through the word vector to calculate two sentences semantic similarity. Finally, we combine the two methods to calculate two Thai language sentences similarity. The proposed method not only considers semantic, but also considers the sentence syntactic structure. The experiment result shows that this method in Thai language sentence similarity computation is feasible.

    2017-02-01

    Full Text Available The main purposes of the study were to determine the attitude of farmers towards Thai Koi farming in a selected area of Mymensingh district. Attempt was also made to identify the problems faced by the farmers in Thai Koi farming. Data were obtained from randomly selected 70 Thai Koi farmers of Shaiod and Ahmedpur villages in Kheruajani Union under Muktagachha Upazila of Mamensingh district during April, 2015. Attitude of the farmers was measured in respect of different aspects of Thai koi production. A three-point rating scale was used to indicate the Thai koi farmers’ response against each statement. The possible score for each respondent could range from 15 to 45 and observed score ranged from 31 to 41. It is evident that ‘I believe that Thai koi farming in pond can supply protein and nutrition to the family members ranked first as a statement in attitude scale of Thai Koi farmers. Second is ‘I like Thai Koi farming because it has higher growth rate than that of other local Koi’. Most of the Thai Koi farmers had highly favourable attitude. Among the problems, ‘high sensitivity to disease of Thai Koi’ got the highest problem confrontation score and stood the first ranked problem and other problem were ‘High price of Thai koi feed’, High price of drugs’ and ‘High price of farm labour’ etc. Farmers suggested from their experiences that there should have need-based spot training on effective management of Thai Koi farming. In achieving this target, Department of Fisheries and allied NGOs may play a crucial role.

    The phylum Mollusca is highly speciose, and is the largest phylum in the marine realm. The great majority of molluscs are shelled, including nearly all bivalves, most gastropods and some cephalopods. The fabulous and diverse colours and patterns of molluscan shells are widely recognised and have been appreciated for hundreds of years by collectors and scientists alike. They serve taxonomists as characters that can be used to recognise and distinguish species, however their function for the animal is sometimes less clear and has been the focus of many ecological and evolutionary studies. Despite these studies, almost nothing is known about the evolution of colour in molluscan shells. This review summarises for the first time major findings of disparate studies relevant to the evolution of shell colour in Mollusca and discusses the importance of colour, including the effects of visual and non-visual selection, diet and abiotic factors. I also summarise the evidence for the heritability of shell colour in some taxa and recent efforts to understand the molecular mechanisms underpinning synthesis of shell colours. I describe some of the main shell pigments found in Mollusca (carotenoids, melanin and tetrapyrroles, including porphyrins and bile pigments), and their durability in the fossil record. Finally I suggest that pigments appear to be distributed in a phylogenetically relevant manner and that the synthesis of colour is likely to be energetically costly. © 2016 Cambridge Philosophical Society.

  7. SYSTEMATICITY OF L1 THAI LEARNERS' ENGLISH INTERLANGUAGE OF DEPENDENT PREPOSITIONS

    2017-01-01

    Full Text Available The study investigates systematicity in English interlanguage of dependent prepositions among L1 Thai learners of L2 English. It is hypothesized that Thai learners show non-random use of English dependent prepositions in their English interlanguage, and that the systematicity is largely attributable to cross-linguistic influence and certain cognitive factors. To test the hypothesis, 30 L1 Thai undergraduate students of L2 English at elementary, intermediate, and advanced proficiency levels took two tests: a Thai–English translation test and a cloze test. The tests involved four types of relationship between English and Thai dependent prepositions: (1 [–prep] in English but [+prep] in Thai, (2 [+prep] in English but [–prep] in Thai, (3 [+prep1] in English but [+prep2] in Thai, and (4 [+prep] in English and [+prep] in Thai. The findings demonstrate that systematicity occurred in the learners’ English usage of prepositions of all such types, possibly due to negative transfer from the learners’ native language. Also, the L2 learners tended to exhibit such systematicity irrespective of their English proficiency level. It may be assumed that the cognitive aspect of L2 learners’ working memory is involved in processing the usage of the four types of English dependent prepositions. The results of the study are expected to shed light on the problems of L2 English interlanguage of dependent prepositions among L1 Thai learners.

    The aim of this study was to investigate the impact of motorcycle to car transitioning and urbanisation on traffic injury rates in Thailand. Analysis of two consecutive surveys of a large national cohort study. Thailand. The data derived from 57,154 Thai Cohort Study (TCS) participants who provided relevant data on both the 2005 and 2009 surveys. Motorcycle and car traffic crash injury self-reported in 2009, with twelve months' recall. In 2009, 5608(10%) participants reported a traffic crash injury. Most crashes involved a motorcycle (74%). Car access increased and motorcycle use decreased between 2005 and 2009. Among those who used a motorcycle at both time points, traffic injury incidence was 2.8 times greater compared to those who did not use a motorcycle at either time point. Multivariable logistic regression models were used to test longitudinal and cross sectional factors associated with traffic crash injury: in the adjusted model, cars were negatively and motorcycles positively associated with injury. Living in an urban area was not injury protective in the adjusted model of traffic crash injury. Ongoing urbanisation in Thailand can be expected to lead to further reductions in road traffic injuries based on transition from motorcycles to cars in urban areas. Cities, however, do not provide an intrinsically safer traffic environment. To accommodate a safe transition to car use in Thailand, traffic infrastructural changes anticipating the growing car density in urban areas is warranted.

    This predictive correlational study was designed to test a comprehensive model of depression for Thai adolescents. This sample included 800 high school students in Chiang Mai, Thailand. Data were collected using self-reported measures of depression, negative automatic thoughts, effective social problem solving, ineffective social problem solving, rumination, parental care, parental overprotection, and negative life events. Structural equation modeling revealed that negative automatic thoughts, effective and ineffective social problem solving mediated the effects of rumination, negative life events, and parental care and overprotection on adolescent depression. These findings provide new knowledge about identified factors and the mechanisms of their influence on depression among Thai adolescents, which are appropriate for targeting preventive interventions. © 2012 Wiley Periodicals, Inc.

    Full Text Available The effect of kefir starter from Wilderness Family Naturals Company on the initial formulation of Thai fermented sausage were evaluated. The differences found among batches in the main microbial populations and pH were not significant. Only, the total acid of batch D (added the kefir starter 15 ml was significantly higher (P0.05. It is concluded that the addition of kefir starter (7 ml could be useful to improve the final quality of Thai fermented sausages. The addition of kefir starter that initiates rapid acidification of the raw meat and that leads to a desirable sensory quality of the end-product are used for the production of fermented sausages, and represents a way of improving and optimizing the sausage fermentation process and achieving tastier, safer, and healthier products.

    The purpose of this study was to investigate the psychometric properties of the modified Thai Spiritual Well-Being Scale in patients with advanced cancer. This cross-sectional study was employed to investigate psychometric properties. Some 196 participants from three tertiary hospitals in Bangkok and suburban Thailand were asked to complete a Personal Information Questionnaire (PIQ), The Memorial Symptom Assessment Scale (MSAS), and the Spiritual Well-Being Scale (SWBS). Validity was determined by known-group, concurrent, and constructs validity. Reliability was estimated using internal consistency by Cronbach's α coefficients. Three factors were extracted: so-called existential well-being, religious well-being, and peacefulness accounted for 71.44% of total variance. The Cronbach's α coefficients for total SWB, EWB, RWB, and peacefulness were 0.96, 0.94, and 0.93, respectively. These findings indicate that the Thai SWBS is a valid and reliable instrument, and it presented one more factor than the original version.

    This study aims to establish the prevalence of risky health behaviors among Thai youth and to characterize the prevalence of these behaviors by gender, age group, educational status, and region. We analyzed data from a population-based, nationally representative, cross-sectional survey of 938 youth aged between 13 and 24 years, sampled from Bangkok and 4 regions of Thailand. The 2011 Youth Risk Behavior Surveillance System questionnaire was used to measure youth risk behaviors. This study finds that 15.9% of respondents had engaged in physical fights, and 8.1% had been cyber bullied. The prevalence of current cigarette smoking, alcohol, and marijuana use were 22.3%, 27.9%, and 2.3%, respectively. The prevalence of risky behaviors among Thai youth were found to be high, including behaviors that contribute to unintentional injuries and violence, unsafe sexual behaviors, and cigarette and alcohol consumption. © 2014 APJPH.

    Full Text Available Seventeen species of herbs established in Thai traditional remedies were microbially decontaminated by gamma-irradiation doses of 7.7 and 8.8 kGy. The herb samples were randomly collected four times from producers in Chiangmai during a 1-year period. These were tested, qualitatively and quantitatively, for total aerobic bacteria, Staphylococcus spp., Salmonella spp., coliform bacteria, and fungi before and after gamma treatment. No microorganisms were found after gamma treatment; and the color, aroma, and texture of the herbs remained normal. The applied dose of gamma irradiation was within the regulatory limits in Thailand (<10 kGy and the main export country (USA< 30 kGy. Gamma irradiation is an effective treatment for microbial decontamination of Thai export herbs.

    Full Text Available Leadership is deeply attached to culture. This study compares leadership styles in Thai and Australian public sectors. The data were collected from staff in public sector settings in Australia and Thailand. The results confirm four leadership styles that suit the public sector culture in both countries: communication-oriented, strategic thinking and planning, relationship building, and conflict management. In the Thai public sector system, leadership that focuses on goal orientation is ranked most highly: Australian public sector organisations focus on leadership that fosters equity among organisational members, creates a supportive environment in the workplace, and facilitates participation. It is evident from this study that significant distinctions between the organisational cultures of Thailand and Australia are matched by marked dissimilarities of preferred leadership styles. Thus, an understanding of local organisational culture is important for effective leadership at all levels.

    This paper tests the effect of systemic risk on deposit market discipline by interacting proxies for systemic risk with bank-specific default-risk variables. Discipline is measured by estimating a supply of deposit funds function at Thai banks from 1992 to 1997. The results show that supply decreases as bank-specific risk increases. Also, the sensitivity of funds to changes in bank-specific risk increases as systemic risk rises. Additionally, depositors decrease their sensitivity to deposit r...

    Highlights: ► Iodine oxide particles were produced from gaseous iodine and ozone. ► Ozone replaced the effect of ionizing radiation in the large-scale THAI facility. ► The mean diameter of the iodine oxide particles was about 0.35 μm. ► Particle formation was faster than the chemical reaction between iodine and ozone. ► Deposition of iodine oxide particles was slow in the absence of other aerosols. - Abstract: The conversion of gaseous molecular iodine into iodine oxide aerosols has significant relevance in the understanding of the fission product iodine volatility in a LWR containment during severe accidents. In containment, the high radiation field caused by fission products released from the reactor core induces radiolytic oxidation into iodine oxides. To study the characteristics and the behaviour of iodine oxides in large scale, two THAI tests Iod-13 and Iod-14 were performed, simulating radiolytic oxidation of molecular iodine by reaction of iodine with ozone, with ozone injected from an ozone generator. The observed iodine oxides form submicron particles with mean volume-related diameters of about 0.35 μm and show low deposition rates in the THAI tests performed in the absence of other nuclear aerosols. Formation of iodine aerosols from gaseous precursors iodine and ozone is fast as compared to their chemical interaction. The current approach in empirical iodine containment behaviour models in severe accidents, including the radiolytic production of I 2 -oxidizing agents followed by the I 2 oxidation itself, is confirmed by these THAI tests.

    To determine the type and number of injuries that occur during the training and practice of Muay Thai kick boxing and to compare the data obtained with those from previous studies of karate and taekwondo. One to one interviews using a standard questionnaire on injuries incurred during training and practice of Muay Thai kick boxing were conducted at various gyms and competitions in the United Kingdom and a Muay Thai gala in Holland. A total of 152 people were questioned, 132 men and 20 women. There were 19 beginners, 82 amateurs, and 51 professionals. Injuries to the lower extremities were the most common in all groups. Head injuries were the second most common in professionals and amateurs. Trunk injuries were the next most common in beginners. The difference in injury distribution among the three groups was significant (pinjury in the three groups. Fractures were the second most common in professionals, and in amateurs and beginners it was sprains and strains (pinjury rates were: beginners, 13.5/1000 participants; amateurs, 2.43/1000 participants; professionals, 2.79/1000 participants. For beginners, 7% of injuries resulted in seven or more days off training; for amateurs and professionals, these values were 4% and 5.8% respectively. The results are similar to those found for karate and taekwondo with regard to injury distribution, type, and rate. The percentage of injuries resulting in time off training is less.

    Full Text Available Thailand is ranked 12th in the world in automotive production, with 57 of the world’s top 100 auto parts manufacturers having factories in Thailand. The industry employs 525,000 workers and represents 12% of Thailand’s gross domestic production (GDP. The automotive industry has also been identified as a core industry in the transition to Thailand 4.0, with digitally enabled, knowledge workers key to its success. This study, therefore, undertook structural equation modeling to conduct an analysis of variables affecting Thai auto parts industry enterprises organizational performance. Using purposive sampling, 320 executives in the Thai automotive industry were selected whose responses to the question constructs were captured using a five-point Likert type agreement scale. Results determined that leadership skills have a significant effect on management skills, and that management skills have a direct and positive effect on management innovation. Additionally, innovation thus far has been viewed as an external process, primarily in response to customer demands or ‘home office’ requirements. Research findings, therefore, suggest that the Thai auto parts industry must develop innovative leadership management which is crucial to sustaining a competitive, domestic capability.

    In this qualitative study, we provide an in-depth understanding of the views of healthy aging among Thai elderly and explore the ways that contribute to healthy aging. Data were collected using focus groups and in-depth interviews in four selected provinces of Thailand, and were analyzed using content analysis. The results revealed that Thai elderly described being healthy as the result of multiple components involving physical, mental, and social well-being. Healthy aging was viewed as an absence of serious diseases, having functional independence, a positive psycho-emotional outlook, and making a social contribution. The factors considered to contribute to healthy aging included activities promoting physical and psychological health, as well as active engagement in social activities. Understanding how the elderly define healthy aging and identifying the most important components and factors that contribute to being healthy provides insight into possible policy implications and interventions to promote health and well-being among Thai elderly. © 2012 Wiley Publishing Asia Pty Ltd.

  7. The sacred foodscapes of Thai Buddhist temples in Sweden

    Full Text Available Thai Buddhist communities are by far the fastest-growing Buddhist establishments in Sweden, and – contrary to other Buddhist congregations that are mainly clustered in the cities – Thai Buddhist temples can be found in sparsely-populated areas and rural parts of Sweden. This article aims to document and analyse the ‘foodscape’ of diasporic Thai Buddhism in Sweden. In particular the article identifies and discusses five different strategies used by local communities- in order to support their temples in urban as well as rural areas: 1 local support, 2 pre-cooking and freezing, 3 pre-organised almsgiving in nearby cities, 4 change of food gifts, 5 change of the nikaya. A temple’s location in a rural area can drive forward a reinterpretation and adaptation of the monk’s rules, and contribute to a changing composition of food gifts. Food performs several functions. In addition to the religious functions that are associated with almsgiving, food can also serve as a means of generating bonding and bridging civic social capital, and providing economic income to temples.

    The Cachazo–He–Yuan (CHY) formula for on-shell scattering amplitudes is extended off-shell. The off-shell amplitudes (amputated Green's functions) are Möbius invariant, and have the same momentum poles as the on-shell amplitudes. The working principles which drive the modifications to the scattering equations are mainly Möbius covariance and energy momentum conservation in off-shell kinematics. The same technique is also used to obtain off-shell massive scalars. A simple off-shell extension of the CHY gauge formula which is Möbius invariant is proposed, but its true nature awaits further study.

    "Quality of life" has become a main focus of interest in medicine. The Pictorial Thai Quality of Life (PTQL) was developed in order to measure the Thai mental illness both in a clinical setting and community. The purpose of this study was to develop the Pictorial Thai Quality of Life (PTQL), having adequate and sufficient construct validity, discriminant power, concurrent validity, and reliability. To develop the Pictorial Thai Quality of Life Test, two samples groups were used in the present study: (1) pilot study samples: 30 samples and (2) survey samples were 672 samples consisting of normal, and psychiatric patients. The developing tests items were collected from a review of the literature in which all the items were based on the WHO definition of Quality of Life. Then, experts judgment by the Delphi technique was used in the first stage. After that a pilot study was used to evaluate the testing administration, and wording of the tests items. The final stage was collected data from the survey samples. The results of the present study showed that the final test was composed 25 items. The construct validity of this test consists of six domains: Physical, Cognitive, Affective, Social Function, Economic and Self-Esteem. All the PTQL items have sufficient discriminant power It was found to be statistically significant different at the. 001 level between those people with mental disorders and normal people. There was a high level of concurrent validity association with WHOQOL-BREF, Pearson correlation coefficient and Area under ROC curve were 0.92 and 0.97 respectively. The reliability coefficients for the Alpha coefficients of the PTQL total test was 0.88. The values of the six scales were from 0.81 to 0:91. The present study was directed at developing an effective psychometric properties pictorial quality of life questionnaire.

    Full Text Available We evaluated the associations between overweight and obesity and socio-economic status (SES, behavioral factors, and dietary intake in Thai adults. A nationally representative sample of 6,445 Thais adults (18–70 years was surveyed during 2004–2005. Information including demographics, SES characteristics, dietary intake, and anthropometrics were obtained. Overall, 35.0% of men, and 44.9% of women were overweight or obese (BMI ≥ 23 kg/m2 using the Asian cut-points. Regression models demonstrated that age was positively associated with being overweight in both genders. In gender-stratified analyses, male respondents who were older, lived in urban areas, had higher annual household income, and did not smoke were more likely to be classified as overweight and obese. Women who were older, had higher education, were not in a marriage-like relationship and were in semi-professional occupation were at greater risk for being overweight and obese. High carbohydrate and protein intake were found to be positively associated with BMI whereas the frequent use of dairy foods was found to be negatively associated with BMI among men. The present study found that SES factors are associated with being classified as overweight and obese in Thai adults, but associations were different between genders. Health promotion strategies regarding obesity and its related co-morbidity are necessary.

Data from the nationally representative 2005 Thai Global Youth Tobacco Survey (n = 15 774) were analyzed using descriptive statistics and logistic regression. Among nonsmoking Thai youth, boys were much more likely to have intention of future smoking (odds ratio [OR] = 0.56, 95% confidence interval [CI] = 0.37-0.84). Younger youth were more likely to be cigarette smokers in the future (OR = 0.70, 95% CI = 0.56-0.88). Youth having the intention of smoking from a friend's cigarette offer were 5.29 times more likely to have intention of future smoking, compared with those who did not (95% CI = 3.75-7.46). Understanding and targeting youth at higher risk for future smoking can provide for a lowering of the youth smoking rate in Thailand and contribute to the country's continued efforts in effective youth tobacco control. © 2013 APJPH.

    2002-01-01

    Full Text Available This paper explores the impact of Thai culture on managing the decision making process in requirements engineering and contribution a better understand of its influence on the management of requirements engineering process. The paper illustrates the interaction of technology and culture and shows that rather than technology changing culture, culture can change the way technology is used. Thai culture is naturally inherent in Thai daily life and Thais bring that into their work practices. The concepts of power and uncertainty in Thai culture contribute toward hierarchical forms of communication and decision making process in Thailand, especially during requirements engineering, where information systems requirements need to be established for further development. The research shows that the decision making process in Thailand tends to take a much longer time, as every stage during requirements engineering needs to be reported to management for final decisions. The tall structure of Thai organisations also contributes to a bureaucratic, elongated decision-making process during information systems development. Understanding the influence of Thai culture on requirements engineering and information systems development will assist multinational information systems consulting organisations to select, adapt, better manage, or change requirements engineering process and information systems developments methodologies to work best with Thai organisations.

    The THAI (THAI = Thermal hydraulics, Hydrogen, Aerosols, Iodine) experimental programme aims to address open questions concerning the behavior of hydrogen, iodine and aerosols in the containment of water cooled reactors. Since its construction in 2000, THAI programme is being performed in the frame of various national projects (sponsored by German Federal Ministry for Economic Affairs and Energy, BMWi) and two international joint projects (under auspices of OECD/NEA). THAI experimental data have been widely used for the validation and further development of Lumped Parameter (LP) and Computational Fluid Dynamics (CFD) codes with 3D capabilities. Selected examples of code benchmark exercises performed based on the THAI data include; hydrogen distribution experiment (ISP-47 and OECD/NEA THAI code benchmark), hydrogen combustion behaviour (ISP-49), hydrogen mitigation by PARs (OECD/NEA THAI-2 code benchmark), iodine/surface interactions, iodine mass transfer, and iodine transport and multi-compartment behaviour (EU-SARNET and EU-SARNET2), thermal-hydraulic tests (German CFD-network). In the present paper, a brief overview on the THAI experiments and their role in the containment safety assessment is discussed.

    Bradbury, Robert J.

    2001-08-01

    More than 40 years have passed since Freeman Dyson suggested that advanced technological civilizations are likely to dismantle planets in their solar systems to harvest all of the energy their stars wastefully radiate into space. Clearly this was an idea that was ahead of its time. Since that time, dozens of SETI searches have been conducted and almost all of them have focused their attention on stars which by definition cannot be the advanced civilizations that Dyson envisioned. I will review the data that created the confusion between Dyson spheres and Dyson shells. The sources that disprove Dyson spheres while still allowing Dyson shells will be discussed. The use of outmoded ideas that have biased the few searches for Dyson Shells that have occurred will be pointed out. An update of the concept of Dyson shells to include our current knowledge of biotechnology, nanotechnology and computer science will be explored. Finally, an approach to setting limits on the abundance of Dyson shells in our galaxy using existing optical astronomical data and future optical satellites will be proposed.

  14. Crazy for Ya Ba: methamphetamine use among northern Thai youth.

    Science.gov (United States)

    Cohen, Anjalee

    2014-07-01

    Since the mid-1990s, Thailand has been one of the largest per capita consumers of methamphetamine pills (ya ba - "crazy drug") in the world and one of the leading consumers of methamphetamine in Southeast Asia, with its youth comprising the majority of users. This article examines the socio-cultural context of methamphetamine use among young Thai in order to understand its widespread appeal. The study is based on 18 months of ethnographic research in Chiang Mai, northern Thailand, between 2002 and 2006 and a follow-up field trip in 2011. In-depth interviews were carried out with 211 young people aged between 15 and 25 in institutional and non-institutional settings. Many of the findings derive from participant observation and informal interviews with a small sample of 20 people. Chiang Mai youth have transformed methamphetamine from a labourers' drug centred on economic utility to a multi-purpose youth drug primarily consumed for pleasure and performance. Ya ba appeals to many young Thai due to its positive image as a modern and fashionable consumer commodity, with confidence in these synthetic pills drawing on and mirroring a broader faith in modern (western) medicine. The growing demand for ya ba in northern Thailand is in part a reflection of the changing social values that have accompanied rapid urbanisation and modernisation in Thailand. In their overwhelming aspiration to be modern, young Thai are consuming ya ba not to rebel against the dominant culture, but to keep up with the demands and expectations of a modern capitalist society.

    Obesity is a worldwide medical condition that leads to physical and psychological impairment. Specific ethnicity, gender and age group are related to different performances of anthropometric indices to predict obesity. The objectives of this study were to estimate the performance of the anthropometric indices for detecting obesity based on percentage of body fat (PBF), to study the correlation among those indices, and to determine the optimal cut-off point of the indices among young Thai adults. This is a cross-sectional study of healthy urban subjects in Khon Kaen, Thailand who were aged 20-39 years. Baseline characteristics and anthropometric measures were collected. PBF was determined using bioelectrical impedance analysis. Demographic data and anthropometric variables were analyzed using descriptive statistics. Receiver-operating characteristic (ROC) curves were used to compare the performance of anthropometric measures as predictors of obesity. One-hundred men and 100 women were recruited for this study. Body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR) and waist-to-stature ratio (WSR) were significantly correlated to PBF. BMI demonstrated the best performance according to the area under the ROC curves in both sexes at cut-off points of 22.5 in women or 25 kg/m(2) in men. WC and WSR showed better performance than WHR to detect obesity. In conclusion, anthropometric indices in young Thai adults were correlated well with PBF to predict obesity as shown in prior reports. Different cut-off points of these indices to define obesity in young Thai adults are recommended. The global cut-off points of WSR in women regardless of ethnicity are supported.

    This research aimed to investigate an optimal condition for astaxanthin production by Phaffia rhodozyma TISTR 5730 in two different media: synthetic YM medium and the medium added with coconut water and diluted with sewage from Thai traditional rice vermicelli plant (coconut water: sewage of 1:0, 1:1, 1:3 and 1:5 ration respectively). The basic medium formulation was composed of 10 g/L glucose, 3 g/L yeast extract, 0.1 g/L K2HPO4, 0.01 g/L NaCl, 0.01 g/L MgSO4 and 0.01 g/L CaCl2 with initial pH 5.5. The cultures were cultivated on 200 rpm shaking bath at 50 °C for 120 hr. It was found that P. rhodozyma TISTR 5370 grew optimally when cultivated in a mixture of coconut water and Thai rice vermicelli sewage (ratio of 1:3), with growth of 3.23 g dry biomass/L and specific astaxanthin production of 680 μg/g dry cell respectively. When fan palm sugar was added to increase reducing sugar from 10 to 15, 20 and 25 g/L, it was demonstrated that the 15 g/L formulation produced highest both dry cell weight (9.66 g/L) and astaxanthin (810 μg/g dry cell weight). Furthermore, when 0.5, 1.0 and 1.5 g/L citric acid was added as supplement, it was found that 1.0-g/L citric acid formulation gave the best result: 10.30 g/L dried cell weight and 930 μg/g dry cell weight astaxanthin. This study provides a promising alternative method of sewage reduction and valorization of wastewater from Thai traditional rice vermicelli plant.

    Double shell capsules are a potential low convergence path to substantial alpha-heating and ignition on NIF, since they are predicted to ignite and burn at relatively low temperatures via volume ignition. Current LANL NIF double shell designs consist of a low-Z ablator, low-density foam cushion, and high-Z inner shell with liquid DT fill. Central to the Double Shell concept is kinetic energy transfer from the outer to inner shell via collision. The collision determines maximum energy available for compression and implosion shape of the fuel. We present results of a NIF shape-transfer study: two experiments comparing shape and trajectory of the outer and inner shells at post-collision times. An outer-shell-only target shot measured the no-impact shell conditions, while an `imaging' double shell shot measured shell conditions with impact. The `imaging' target uses a low-Z inner shell and is designed to perform in similar collision physics space to a high-Z double shell but can be radiographed at 16keV, near the viable 2DConA BL energy limit.

    2016-12-01

    Muay Thai is a combat sport of Thailand that uses stand-up striking along with various clinching techniques. Currently, little is known about the injuries and risk factors for injuries among Muay Thai fighters. Gaining more insight into the nature and frequency of injury in this sport provides part of the overall sports injury picture, within the larger burden of injury as a public health issue. Generating this information is a critical first step toward the broader goal of improving the health and safety of Muay Thai fighters engaged in competition. This study is based upon a survey of 195 Muay Thai fighters. Participants were asked to complete a retrospective web survey on fight-related injuries. Regression analyses were conducted to determine whether injuries during sanctioned fights were related to factors such as fight experience, use of protective equipment, and injury history. Participants were aged 18 to 47 years old (median 26), predominantly male (85.9%), and white (72.3%). Respondents were professional (n = 96, 49.2%) and amateur (n = 99, 50.8%). Fighters reported a mean fight experience of 15.8 fights. Of the 195 respondents, 108 (55.4%) reported sustaining an injury during the most recent fight. The primary body region injured was the extremities (58%) versus the head, with a lower amount of self-reported concussions (5.4%). Nearly 2/3 (66.7%) of all injured fighters reported that the injury did not interfere with the bout outcome. Nearly 25% reported they missed no training time as a result of the injury. Injuries were related to professional fighter status (OR = 2.5, 95% CI = 1.4-4.5), fight experience (OR = 2.7, 95% CI = 1.5-4.9), weight class (OR = 0.923 heavy versus light, 95% CI = .86-.99), age (OR = 0.90 > 26 versus ≤26, 95% CI = .85-.95), use of protective equipment (OR = .46, 95% CI = .26-.82) and previous injury (OR = 1.81, 95% CI = .98-3.3).

    Highlights: • Thai industrial sector has been modelled using AIM/Enduse model. • Potential mitigation of CO 2 for 2050 is approximately 20% from Baseline scenario. • Abatement cost curves show that varied counter measures are practical in the industrial sector. • Energy security is enhanced due to CO 2 mitigation in the LCS scenario. - Abstract: Energy plays a dominant role in determining the individual competitiveness of a country and this is more relevant to emerging economies. That being said, energy also plays an important and ever expanding role in carbon emissions and sustainability of the country. As a developing country Thailand’s industrial sector is vibrant and robust and consumes majority of the energy. In addition, it also has the highest CO 2 emissions, provided the emissions of power generation are taken into account. Industry also accounts for the highest consumption of electricity in Thailand. The objective of this study is to model the Thai industrial energy sector and estimate the mitigation potential for the timeframe of 2010–2050 using the principles of Low Carbon Society (LCS). In addition, the paper would also evaluate emission tax as a key driver of Greenhouse Gas (GHG) mitigation along with Marginal Abatement Cost (MAC) analysis. Another secondary objective is to analyse the impact of mitigation on energy security of the industrial sector. The Thai industrial sector was modelled using AIM/Enduse model, which is a recursive dynamic optimisation model belonging to the Asia–Pacific Integrated Model (AIM) family. Thai industrial sector was divided into nine sub-sectors based on national economic reporting procedures. Results suggest that the mitigation potential in 2050, compared to the Baseline scenario, is around 20% with positive impacts on energy security. The Baseline emission will approximately be 377 Mt-CO 2 in the industrial sector. All four indicators of energy security, Primary Energy Intensity, Carbon Intensity, Oil

    Full Text Available The presence of Cd, Cu, Zn, Ni, Fe, Al, Zn, Mn, Cr, and Sn were attributed to metal industries. Cu contamination was associated with piggery industry. Shipping activities contribute to elevated levels of Pb, Cu and As. Elevated levels of metals in the sediments are attributed to anthropogenic activities. Samples were collected in April 2012 and analysed using inductively coupled plasma mass spectrometry (ICP-MS. Fe is the most abundant metal in the tissue and shell compared to the rest of the metals. The concentrations of heavy metals in the soft tissues of Nerita lineata taken from Tanjung Harapan follow this order: Fe > Zn > Ni > Cu > Cd while in Thais bitubercularis, the metal concentrations were higher following the order of Fe > Zn > Cu > Ni > Cd. The samples taken from Teluk Kemang were higher and exhibited different trend for both organisms. Results from this study are useful for further exploration of Thais bitubercularis as accumulators of Cu, Cd, and Zn. For recommendation, more studies on monitoring the concentration level of heavy metals in marine environment should be done regularly and increase numbers of samples use to biomonitor the heavy metals in marine environment as it is important to have information or data regarding the quality of marine environment in order to control pollution such as water pollution from being contaminated with heavy metals. This is essential as the pollutants emit in the marine environment may affect marine lives as well as human’s health

    Living in a care home is a source of stigma in Thai culture, although there is currently no measurement tool in the Thai language specifically designed to assess internalized stigma in care home residents. The Thai Version of Internalized Stigma of Living in a Care Home (TIS-LCH) scale was developed and tested for its psychometric properties among Thai older residents. The Thai version of Internalized Stigma of Mental Health Illness (ISMI) Scale was revised into the TIS-LCH by replacing the word of "mental health illness" to "living in a care home." Content validity of the TIS-LCH was determined through expert review (n = 6), and reliability testing was undertaken with older care home residents (n = 128). The TIS-LCH showed good internal consistency, with a Cronbach's alpha of .87. Test-retest reliability coefficient of TIS-LCH was excellent for the full scale (ICC = .90). The Thai version of IS-LCH (TIS-LCH) is a valid and reliable measurement tool for assessing internalized stigma in Thai care home residents. The IS-LCH will be a useful research tool to assess internalized stigma in older adults living in care settings. Understanding stigma will help health and social care professionals to plan interventions aimed at reducing or preventing negative emotional reactions and negative behavioural responses toward stigma, which are known to be associated with mental illness and particularly depression among this population.

    To investigate emergent literacy skills, including phonological awareness when presented with an initial phoneme-matching task and letter knowledge when presented with a letter-naming task in Thai preschoolers, and to identify key factors associated with those skills. Four hundred twelve typically developing children in their final kindergarten year were enrolled in this study. Their emergent reading skills were measured by initial phoneme-matching and letter-naming tasks. Determinant variables, such as parents' education and teachers' perception, were collected by self-report questionnaires. The mean score of the initial phoneme-matching task was 4.5 (45% of a total of 10 scores). The mean score of the letter-naming task without a picture representing the target letter name was 30.2 (68.6% of a total of 44 scores), which increased to 38.8 (88.2% of a total of 44 scores) in the letter-naming task when a picture representing the target letter name was provided. Both initial phoneme-matching and letter-naming abilities were associated with the mother's education and household income. Letter-naming ability was also influenced by home reading activities and gender. This was a preliminary study into emergent literacy skills of Thai preschoolers. The findings supported the importance of focusing on phonological awareness and phonics, especially in the socioeconomic disadvantaged group.

    In this research, the natural radioactivity concentrations and their respective annual effective dose of the naturally occurring radionuclides 226 Ra, 228 Ra and 40 K in selected medicinal herb plants were investigated. Seven kinds of popular Thai medicinal herb plants had been studied: turmeric, ginger, safflower, moringa, gotu kola, garlic and alexandria senna. The radiological risk associated with the use of these medicinal plants was assessed. The activity concentrations of 226 Ra, 228 Ra and 40 K were determined using the gamma-ray spectrometry technique. The radioactivity concentrations were found to range from less than 0.20 to 6.67 Bqkg -1 for 226 Ra, less than 0.10 to 9.69 Bqkg -1 for 228 Ra, and from 159.42 to 1216.25 Bqkg -1 for 40 K. Gotu kola showed the highest activity concentrations of 226 Ra and 228 Ra, while ginger showed the highest activity concentration of 40 K. The total annual effective dose due to ingestion of these herb plants were found to range from 0.0028 to 0.0097 mSvy -1 with an average value of 0.0060±0.0001 mSvy -1 . The results conclude that the Thai medicinal herb plants samples from this research are considered safe in terms of the radiological hazard. (paper)

    This work aims to study the antioxidants capacity, Total phenolic content and antibacterial activity of Thai medicinal plant for the treatment of dermatitis-related inflammations, Capparis micracantha. Crude extract from stem of Thai medicinal plant was extracted with hexane, ethyl acetate, methanol and water. The antioxidant activities (IC50) was evaluated with 1,1-diphenyl-1-princylhydrazyl (DPPH) radical scavenging assay. Total phenolic content (TPC) was determined by using Folin-Ciocalteu method. Bacterial activities was tested with four human pathogenic bacteria; Escherichia coli, Listeria monocytogenes, Staphylococcus aureus and Stapylococcus epidermidis by using agar diffusion assay. Minimum Inhibition Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were also determined by broth dilution method. For antioxidant activity, the methanol fraction from stem extract showed the highest activity with an IC50 of 2.4 mg/ml. Water extraction was the high TPC with 10,136.9 mg GAE/g dry weight. Methanol and water extraction showed the remarkable inhibition of bacterial growth was shown against L. monocytogenes and S. aureus. In addition, ethyl acetate, methanol and water fraction from stem extract against S. epidermidis. The present finding suggests that the extract of C. micracantha could be used to discover bioactive natural products that may serve as pharmaceutical products.

    Full Text Available Background: Men are overrepresented with regard to alcohol addiction and in terms of alcohol treatment worldwide. In Thailand, alcohol consumption continues to rise, but few of those afflicted with alcohol addiction attend alcohol treatment programs, even though there is universal care for all. No comprehensive studies have been done on men's experiences with addiction and alcohol treatment programs in Thailand. Objective: The aim of this study was to explore men's experiences in terms of the ‘pros and cons of alcohol consumption’ in order to identify the barriers that exist for Thai men with regard to alcohol addiction and the decision to stop drinking. Design: Purposive sampling was applied in the process of recruiting participants at an alcohol clinic in a hospital in Thailand. Thirteen men with alcohol addiction (aged 32–49 years were willing to participate and were interviewed in thematic interviews. The analysis of the data was done with descriptive phenomenology. Results: Through men's descriptions, three clusters of experiences were found that were ‘mending the body’, ‘drinking as payoff and doping related to work’, and ‘alcohol becoming a best friend’ as ways of describing the development of addiction. Conclusions: The results highlight the importance of addressing concepts of masculinity and related hegemonic ideas in order to decrease the influence of the barriers that exist for Thai men with alcohol addiction with regard to entering treatment and to stop drinking.

    Full Text Available The focus of this study is the transfer of marketing knowledge within Thai joint venture firms. The perspectives of Thai managers were surveyed using a structured instrument. The analysis identifies seven dimensions of marketing management knowledge: promotion management, price management, logistics management, product innovation management, strategic marketing management, cross-cultural management, and target marketing management. The incidence of transfer is highest for activities in strategic marketing management, followed by price management. Transfer in product innovation management and target marketing management tends to vary with the age of the joint venture. Joint venture firms with foreign partners originating from Western, advanced, industrialised nations recorded the highest incidence of knowledge transfer occurring within product innovation management. This trend also holds true for the management of promotion activities. The incidence of transfer in target marketing management is lowest among firms with foreign partners from neighbouring nations. The incidence of knowledge transfer within product innovation and target marketing also tends to vary with the age of the joint venture. An analysis based on industry classification revealed that the transfer of knowledge regarding logistics management occurs most for firms in the manufacturing sector. In the service sector, the highest incidence of knowledge transfer within the areas of promotion management and target marketing management occurred in the agricultural sector.

    2013-09-01

    Despite known health risks related to the use of powdered latex gloves (PLGs), they are still widely used in hospitals in developing countries due to the high cost of alternatives. To determine the prevalence of dermal and respiratory symptoms associated with latex glove use in nurses in Thailand and evaluate the influence of previously reported occupational risk factors in this population. A cross-sectional study in female nurses working in three Thai hospitals. Participants completed a questionnaire on demographics, occupational and personal history, use of latex products at work and dermal and respiratory symptoms attributed to occupational use of latex gloves. Of 899 nurses, 18% reported health effects attributed to the use of latex products. After adjustment for confounding, occupational risk factors associated with increased reporting of dermal symptoms included wearing more than 15 pairs of PLG per day (odds ratio (OR): 2.10, 95% confidence interval (CI): [1.32-3.34]), using chlorhexidine (OR: 2.07, 95% CI: [1.22-3.52]) and being an operating theatre nurse (OR: 2.46, 95% CI: [1.47-4.12]). Being a labour ward nurse (OR: 3.52, 95% CI: [1.26-9.85]) was the only factor associated with increased reporting of respiratory symptoms. Continuing use of PLGs in Thai nurses is associated with increased prevalence of dermal symptoms compared with data from developed countries. Measures to reduce such health effects are well established and should be considered. Additionally, replacement of chlorhexidine with an alternative detergent seems advisable.

    Full Text Available Several antioxidant nutrients have been described to inversely correlate with asthma. In order to quantify the intake of these substances, it is possible to measure skin levels by Raman spectroscopy, a novel non-invasive technique that can also be used in children. This cross-sectional school-based study involved 423 children from a rural area of Thailand. Asthmatic children were diagnosed according to a Health Interview for Asthma Control questionnaire. Skin carotenoid levels were measured with Raman spectroscopy. Demographic data were obtained by directly interviewing children and their parents, whereas anthropometric parameters were measured by trained staff. Intake of carotenoids, vitamin A and C were evaluated by a food frequency questionnaire. Overall incidence of asthma in Thai schoolchildren (aged 3.5-17.8 years was 17.3%. There was no significant difference in dietary intake of carotenoids and vitamin A and C, and skin carotenoid level between asthmatic and nonasthmatic children. Skin carotenoid level significantly correlated with all carotenoids and vitamin A intake (P<0.05. Carotenoids and vitamin A and C intakes, and skin carotenoid levels were not associated with the risk of asthma in Thai children. Skin carotenoids correlated with all carotenoids and vitamin A intake in mild to moderate degrees. Raman spectroscopy was confirmed to be a useful tool to determine antioxidant skin levels.

    Full Text Available Objectives. To determine the dietary patterns of middle-aged Thais and their association with metabolic syndrome (MetS. Methods. The Thai National Health Examination Survey IV data of 5,872 participants aged ≥30–59 years were used. Dietary patterns were obtained by factor analysis and their associations with Mets were examined using multiple logistic regression. Results. Three major dietary patterns were identified. The first, meat pattern, was characterized by a high intake of red meat, processed meat, and fried food. The second, healthy pattern, equated to a high intake of beans, vegetables, wheat, and dairy products. The third, high carbohydrate pattern, had a high intake of glutinous rice, fermented fish, chili paste, and bamboo shoots. Respondents with a healthy pattern were more likely to be female, higher educated, and urban residents. The carbohydrate pattern was more common in the northeast and rural areas. Compared with the lowest quartile, the highest quartile of carbohydrate pattern was associated with MetS (adjusted odds ratio: 1.82; 95% CI 1.31, 2.55 in men and 1.60; 95% CI 1.24, 2.08 in women, particularly among those with a low level of leisure time physical activity (LTPA.

    The Okha Shell Limestone Member of Chaya Formation is the coarse grained, shell rich deposit commonly recognized as the beach rocks. It has been age bracketed between Late Pleistocene and Holocene. Late Quaternary sea level changes have been studied with beach rocks along the Saurashtra coastal region. The present study has been carried out in the Okhamandal area of the Saurashtra peninsula especially on the Okha Shell Limestone Member as exposed at various locations along the coast from north to south. Temporal and spatial correlations of the observations have revealed three events in the Okha Shell Limestone Member of Chaya Formation that are correlated laterally. The events show depositional breaks represented by discontinuity surfaces, the taphofacies varieties and ichnological variations. The present study in the context of available geochrnological data of the region suggests a prominent depositional break representing low sea level stand (regression) during an Early Holocene during the deposition of Okha Shell Limestone Member.

    "Tian Op", a traditional Thai scented candle, is used for the smoking and flavoring of sweets, cakes, and other desserts for the purpose of adding a unique aroma to the final product. Gas chromatography-olfactometry, aroma extract dilution analysis, and GC-MS were applied to identify the potent odorants in two types of traditional Thai desserts ("num dok mai" and "gleep lum duan") prepared using a Tian Op smoking process. On the basis of the results of AEDA and calculated odor-activity values, the predominant odorants in the Tian Op flavored desserts were vinyl ketones (C(5)-C(9)), n-aldehydes (C(5)-C(11)), (E)-2-unsaturated aldehydes (C(8)-C(11)), and omega-1-unsaturated aldehydes (C(8) and C(9)). Sensory studies of model mixtures confirmed the importance of n-aldehydes, omega-1-unsaturated aldehydes, and guaiacol as predominant odorants; however, the results showed that vinyl ketones and (E)-2-unsaturated aldehydes, despite having high odor-activity values, may be of only minor importance in the typical aroma profiles of traditional Tian Op smoked desserts.

  1. Shells on elastic foundations

    1977-01-01

    No realistic analytical work in the area of Shells on Elastic Foundations has been reported in the literature. Various foundation models have been proposed by several authors. These models involve one or more than one parameters to characterise the foundation medium. Some of these models cannot be used to derive the basic equations governing the behaviour of shells on elastic foundations. In the present work, starting from an elastic continuum hypothesis, a mathematical model for foundation has been derived in curvilinear orthogonal coordinates by the help of principle of virtual displacements, treating one of the virtual displacements as known to satisfy certain given conditions at its edge surfaces. In this model, several foundation parameters can be considered and it can also be used for layered medium of both finite and infinite thickness. (Auth.)

    Cognitive impairment, such as dementia, has emerged as the leading public health problem among the elderly. Therefore, early detection of the disorder and providing appropriate healthcare and management is important, particularly, for the patients with comorbid diabetes who require long-term treatment strategies. In Thailand, because of a large number of elderly patients with diabetes, and time constraints in primary care settings, a short and effective cognitive screening test is required. The Mini-Cog is a short and valid cognitive screening test that was specifically designed for use in primary care settings. The present study translated the English language version into a Thai language version, and then measured the interrater reliability and concurrent validity. The processes of cross-language translation were carried out to develop a Thai language version of the Mini-Cog. A total of 21 Thai older adults with type 2 diabetes with a mean aged of 69 ± 7 years were recruited into a study investigating the interrater reliability and concurrent validity of the Mini-Cog Thai version in one primary care center in Thailand. The Mini-Cog Thai version showed a good interrater reliability (K = 0.80, P validity (r = 0.47, P = 0.007, 95% CI 0.37,0.55) with the Mini-Mental State Examination Thai 2002. The findings show that the Thai version of the Mini-Cog is a reliable, performance-based tool in the screening for cognitive function in primary care settings in Thailand. It is recommended that it could be used as a new cognitive screening test for the aging population in the Thai community. © 2014 Japan Geriatrics Society.

    The current aim is to examine the prevalence of intimate partner violence (IPV) among Thai women residing in Sweden and its association with mental health. We also investigate the potential influence of social isolation and social capital regarding the association between IPV and mental health outcome. A public health questionnaire in Thai was distributed by post to the entire population of Thai women, aged 18-64, residing in two regions in Sweden since 2006. Items included aspects related to IPV (physical/sexual/emotional), sociodemographic background, physical health, mental health (GHQ-12), social isolation, and social capital (i.e. social trust/participation). The response rate was 62.3% (n=804). Prevalence of lifetime reported IPV was 22.1%, with 20.5% by a previous partner and 6.7% by a current partner. Previous IPV exposure was significantly related to current IPV exposure, and all IPV exposure measures were significantly related to poor mental health. However, Thai women experiencing IPV by a current partner were more at risk for poor mental health than Thai women with previous or without any experience of IPV. Also, among all women exposed to IPV, those with trust in others and without exposure to social isolation seemed to have partial protection against the adverse mental health consequences associated with IPV. Most Thai women had never been exposed to IPV, and after migrating to Sweden, women had lower IPV exposure than in Thailand. However, the increased risk for poor mental health among those Thai women exposed to IPV suggests the need for supportive measures and targeted interventions to prevent further injuries and adverse health consequences. Although poor mental health in Thai women represents an obstacle for integration, the potential resilience indicated in the group with high social trust and without exposure to social isolation suggests that such aspects be included in the program designed to facilitate integration.

    2001-01-01

    In vivo studies were conducted using marine snails (Thais chocolata) artificially contaminated in a tank containing sea water inoculated with a pure culture of Vibrio cholerae, such that 10 5 colony forming units per gram (CFU/g) were uptaken by the mollusks in 1.5 h. A radiation D 10 value of 0.12 kGy was determined for V. cholerae upon subsequent irradiation of the live snails at doses in the range 0.0-4.0 kGy. A second series of tests were conducted using naturally contaminated, non-inoculated snails, shelled and packaged simulating commercial procedures, irradiated at 0.0-3.0 kGy, and stored at 2-4 deg. C. These tests indicated that a dose of 2.0 kGy was optimal to extend the microbiological shelf-life of the snails to 21 days without inducing significant adverse sensory or chemical effects. Non-irradiated snails similarly treated and stored spoiled after only seven days. (author)

    Background Exercise has been shown to be effective in cardiovascular endurance in the elderly. We studied the effect of Thai dancing on physical performance of Thai elderly. Methods This was an open-labeled, randomized intervention study. The Thai dancing group exercised for 40 minutes three times a week for 6 weeks. Physical performance ability was the primary outcome, including a 6-minute walk test (6MWT), five-times sit-to-stand (FTSST), and a sit-and-reach test measured before and after 6 weeks of intervention. Results There were 42 subjects enrolled in the study, and 38 female subjects completed (20 in Thai dance group, 18 controls), with an average age of 65.8 ± 5.1 years. The Thai dance group had significantly better physical performance in all measurements at the end of the study. The 6MWT was longer (416.7 ± 58.7 versus 345.7 ± 55.1 m; P = 0.011), FTSST was quicker (10.2 ± 1.5 versus 14.4 ± 3.3 seconds; P dance group than the control group. Conclusion Thai dance can improve physical performance in recently aged (elderly) female adults. PMID:23950640

    The impact of climate change is estimated to be particularly severe in Thailand. Overall, the country faces an increase in surface temperatures, severe storms and floods, and a possible increase in the number of mass disasters in the region. It is extremely important that forensic scientists have access to sex estimation methods developed for use on a Thai population. The goal of this project is to evaluate the accuracy of sex estimation discriminant functions, created using contemporary Mexican and Greek populations, when applied to a contemporary Thai sample. The length of the glenoid cavity (LGC) and breadth of the glenoid cavity (BGC) were measured. The sample included 191 individuals (95 males and 96 females) with age ranges from 19 to 96years old. Overall, when the Mexican and Greek discriminant functions were applied to the Thai sample they showed higher accuracy rates for sexing female scapulae (83% to 99%) than for sexing male scapulae (53% to 92%). Size comparisons were made to Chilean, Mexican, Guatemalan, White American, and Greek populations. Overall, in males and females of the Thai sample, the scapulae were smaller than in the Chilean, Mexican, White American, and Greek populations. However, the male and female Thai scapulae were larger than in the Guatemalan sample. Population-specific discriminant functions were created for the Thai population with an overall sex classification accuracy rate of 83% to 88%.

    Thai classical dance is a traditional dramatic art, the technique of which has many features in common with South East Asian performing art. The choreographic patterns consist of various forms of balance control together with limb movements in slow rhythm. The grace and beauty of the dancer are dependent on how well the limb movements curve and angle. The relationship of whole body proportion and balance control in various patterns of support base is also important. The purpose of this study was to compare balance abilities between Thai classical dancers and non-dancers in different balance conditions. Twenty-five Thai classical dancers and 25 non-dancers performed the modified Sensory Organization Test (mSOT) and were further challenged by adding dynamic head tilts (DHTs) in four different directions during mSOT. Mixed model ANOVA was applied to determine the equilibrium score in each balance condition and also the interaction between dancer and non-dancer groups. It was found that Thai classical dancers achieved better equilibrium scores in all mSOT conditions except the least challenging one. Moreover, additional multitask conditions (mSOT+DHT) were revealed to profoundly affect differences between dancers and controls. In conclusion, Thai classical dancers demonstrated a better ability to maintain postural stability during different challenging postural tests. This information suggests various ways of putting the practice of Thai classical dance to use in the future.

    To determine the prevalence ofFacebook (FB) addiction and its related factors among Thai high school students. This cross-sectional study was performed among 972 high school students in four provinces associated with high economic prosperity in Thailand: Bangkok, Ubon Ratchathani, Chiang Mai and Songkhla, utilizing a multistage cluster sampling technique. A self-administrative questionnaire was produced composing of three parts; demographic data, a Thai version of the Bergen Facebook Addiction Scale (Thai-BFAS) and the Thai version of the General Health Questionnaire-28 items. Multivariate analysis was employed to analyze thefactors associated with FB addiction. The prevalence ofFB addiction amongst Thai adolescents was 41.8% (95% CI; 38.6, 45.2). Related factors included gender school location, sufficiency ofpersonalfinance, devices ofFB access, duration ofstaying online via FB, andFB usage during holidays. In addition, every 1-hour increase in usage enhanced the risk for FB addiction (OR = 1.12, 95% CI; 1.05, 1.19). The prevalence of FB addiction in Thai high school students was found to be higher than in many other countries. Relatedfactors should be controlled in order to reduce FB addiction and its detrimental impacts, such as behavior modification and the promotion of healthier free-time activities. Further studies are recommended to understand why FB addiction is so high in Thailand.

    Ethnic and racial differences in infant skin have not been well characterized. The purpose of this study was to establish whether there are ethnic differences and similarities in the stratum corneum (SC) functions of Thai and Chinese infants. Healthy infants 6 to 24 months of age (N = 60; 30 Thai, 30 Chinese) who resided in Bangkok, Thailand, were enrolled. Transepidermal water loss (TEWL) and SC hydration (capacitance) on the thigh, buttock, and upper arm were measured. Ceramide content was determined in the SC on the upper arm. SC hydration was not remarkably different between the two ethnicities at any site measured, but TEWL was significantly higher in Chinese infants than in Thai infants at all sites. Hydration of the SC was not significantly correlated with age in either ethnicity. TEWL had significant but weak correlations with age on the thigh and upper arm in Thai infants. Ceramide content was significantly higher in Chinese SC than in Thai SC. No relationship between ceramide content and TEWL or hydration was observed in either ethnicity. The significant differences in TEWL and ceramide contents between Chinese and Thai infant skin could prove useful in designing skin care and diapering products that are best suited for each ethnicity. © 2017 Wiley Periodicals, Inc.

    The work presented in this paper compares traditional Chinese medicine and traditional Thai medicine, expounding on origins, academic thinking, theoretical system, diagnostic method and modern development. Based on a secondary analysis of available literature, the paper concentrates on two crucial historical developments: (1) the response to, and consequences of, the impact of the Western medicine; and (2) the revival of traditional medicine in these two countries and its prospects. From a comparative perspective, the analysis has led to the conclusion that the rise and fall of traditional medicine is an issue closely related with social and political issues; and the development of traditional medicines requires national policy and financial support from governments, human resource development, the improvement of service quality, and the dissemination of traditional medicine knowledge to the public. In addition, this paper also suggests deepening exchanges and cooperation between China and Thailand, strengthening cooperation between traditional medicine and medical tourism.

    Talent development in Thailand and Malaysian service firms has become a prioritized human resource management practice as these societies move toward knowledge-based economies. This paper discusses talent management in the social, organizational and managerial context of firms in Thailand...... and Malaysia, and argues that such structures often counterbalance investments made in talent development. The paper concludes that new human resource management practices do not produce a difference per se. It is the mindset and attitude of various managers that makes the difference. The learning...... for practitioners is that they need to adapt existing social and organizational structures to their new human resource management practices. The paper is based mainly on qualitative interviews with human resource managers from Thai and Malaysian service firms....

Methods: This is a 16-week, randomized, parallel, open-label, controlled trial in a menopausal clinic in a tertiary health care center in Northeastern Thailand. The intervention group received a 60-minute session of MR training and were encouraged to practice 15–20 minutes a day, at least 5 days a week. The control group received lifestyle education, including diet and exercise. The primary and secondary outcomes were systolic and diastolic blood pressure (SBP and DBP. Results: Of 432 participants, 215 and 217 were randomly allocated to the MR and control groups, respectively. Of those, 167 participants in the MR group and 175 participants in the control group completed the study. The SBP was significantly more reduced in the MR group, with a mean of 2.1 mmHg (P < 0.001. There was no significant difference between groups on the changed DBP. Conclusion: The MR technique may be effective in lowering SBP in Thai postmenopausal women visiting a menopause clinic. Its efficacy may be observed as soon as 4 weeks after start of treatment. Long-term and combined relaxation therapy and antihypertensive agents are warranted in a large cohort of this population.

    Rhineland leadership practices contrast sharply with the prevailing Anglo/US business model of short-term maximization of profitability, and are said to lead to greater corporate sustainability, at least in highly developed economies. However, the applicability of Rhineland leadership to less developed economies has not yet been demonstrated. This paper sets out to compare the business practices of a social enterprise that delivers healthcare services in Thailand and Avery's 19 sustainable leadership practices derived from Rhineland enterprises. Adopting a case study approach, multi-data collection methods included non-participant observations made during visits to the enterprise, and reference to internal and published documentation and information. Semi-structured interview sessions were held with many stakeholders, including top management, staff, patients and a former consultant. In the Thai healthcare organization studied, evidence was found for compliance with 15 of Avery's 19 sustainable leadership elements, but to varying degrees. The elements were grouped into six core sets of practices: adopting a long-term perspective, staff development, organizational culture, innovation, social responsibility, and ethical behavior. One element was found to be not applicable, and no evidence was found for conformity with Rhineland principles on the remaining three sustainable practices. The paper concludes that Avery's 19 Rhineland practices provide a useful framework for evaluating the corporate sustainability of this Thai enterprise. Healthcare enterprises in Thailand and possibly in other Asian countries that wish to sustain their organizational success could adopt Avery's 19 Sustainable Leadership Grid elements to examine their leadership practices, and adjust them to become more sustainable. The relevance of Rhineland sustainable leadership principles to enterprises in less developed economies remains to be investigated. This study attempts to uncover this unknown.

  8. Wrinkling of Pressurized Elastic Shells

    2011-10-01

    We study the formation of localized structures formed by the point loading of an internally pressurized elastic shell. While unpressurized shells (such as a ping-pong ball) buckle into polygonal structures, we show that pressurized shells are subject to a wrinkling instability. We study wrinkling in depth, presenting scaling laws for the critical indentation at which wrinkling occurs and the number of wrinkles formed in terms of the internal pressurization and material properties of the shell. These results are validated by numerical simulations. We show that the evolution of the wrinkle length with increasing indentation can be understood for highly pressurized shells from membrane theory. These results suggest that the position and number of wrinkles may be used in combination to give simple methods for the estimation of the mechanical properties of highly pressurized shells. © 2011 American Physical Society.

    Accelerator controls systems provide parameter display pages which allow the operator to monitor and manipulate selected control points in the system. Display pages are generally implemented as either hand-crafted, purpose-built programs; or by using a specialized display page layout tool. These two methods of display page development exhibit the classic trade-off between functionality vs. ease of implementation. In the Direct Manipulation Shell we approach the process of developing a display page in a manifestly object-oriented manner. This is done by providing a general framework for interactively instantiating and manipulating display objects. (author)

It identifies the recommended motivational factors that influence the airline customers’ decision to their airline choices. Airlines use different customer relationship management programs to attract returning customers.  This paper suggested the most attractive motivation factors for Thailand's air travel market. Design/methodology/approach: This research paper is an attempt to study and identify the factors, including loyalty program, distribution channel, customer services, promotions and other influence causes that affected the customer preference in the airline ticket purchasing behavior in Thailand. A questionnaire survey was conducted with the sample identified through unrestricted non probability sampling technique at four major airports in Thailand. The data collected are analyzed to identify the favorable drivers that lead to customer decision on airline choice. Findings: The result from the study has demonstrated that price, and promotion has a significant impact on customer preference and positively leads to repurchase intention for their future travel. Moreover, flight schedules are also a main factor influencing the travelers’ final decision on airline choice. However, when the promotional strategies and schedule are comparable between airlines, customers are attracted by the airline amenities and services. Loyalty program (frequent-flier program flier program is showing a less attractive motivator while distribution channel demonstrates the least important affecting the travelers’ choice of airline. Originality/value: The paper begins with an overview of previous research in the area of airlines customer relationship management and then moves on to what is currently being implemented by the airlines.

    Recent technologic developments have required a more comprehensive approach to the behavior of rock mass or rock substance plus discontinuities than was adequate previously. This work considers the inherent problems in such operations as the storage of hot or cold fluids in caverns and aquifers, underground storage of nuclear waste, underground recovery of heat from hydrocarbon fuels, tertiary recovery of oil by thermal methods, rapid excavation of large openings at shallow to great depths and in hostile environments, and retrofitting of large structures built on or in rock. The standardization of methods for determining rock properties is essential to all of the activities described, for use not only in design and construction but also in site selection and post-construction monitoring. Development of such standards is seen as a multidisciplinary effort

    Basic igneous rocks, containing less than 52% SiO 2 , constitute an important part of the Finnish Archaean and Proterozoic crust. In the Archaean crust exist two units which contain the majority of the basic rocks. The Arcaean basic rocks are metavolcanics and situated in the Greenstone Belts of Eastern Finland. They are divided into two units. The greenstones of the lower one are tholeiites, komatiites and basaltic komatiites. The upper consists of bimodal series of volcanics and the basic rocks of which are Fe-tholeiites, basaltic komatiites and komatiites. Proterozoic basic rocks are divided into seven groups according to their ages. The Proterozoic igneous activity started by the volominous basic magmatism 2.44 Ga ago. During this stage formed the layered intrusions and related dykes in the Northern Finland. 2.2 Ga old basic rocks are situated at the margins of Karelian formations. 2.1 Ga aged Fe-tholeiitic magmatic activity is widespread in Eastern and Northern Finland. The basic rocks of 1.97 Ga age group are met within the Karelian Schist Belts as obducted ophiolite complexes but they occur also as tholeiitic diabase dykes cutting the Karelian schists and Archean basement. The intrusions and the volcanics of the 1.9 Ga old basic igneous activity are mostly encountered around the Granitoid Complex of Central Finland. Subjotnian, 1.6 Ga aged tholeiitic diabases are situated around the Rapakivi massifs of Southern Finland, and postjotnian, 1.2 Ga diabases in Western Finland where they form dykes cutting Svecofennian rocks

    We present photographic representations of the combination of two Hi surveys, so as to eliminate the survey boundaries at Vertical BarbVertical Bar = 10 0 . We also present high-contrast photographs for particular velocities to exhibit weak Hi features. All of these photographs were used to prepare a new list of Hi shells, supershells, and shell-like objects. We discuss the structure of three shell-like objects that are associated with high-velocity gas, and with gas at all velocities that is associated with radio continuum loops I, II, and III. We use spatial filtering to find wiggly gas filaments: ''worms'': crawling away from the galactic plane in the inner Galaxy. The ''worms'' are probably parts of shells that are open at the top; such shells should be good sources of hot gas for the galactic halo

    One of the more unusual rocks at the site is Ginger, located southeast of the lander. Parts of it have the reddest color of any material in view, whereas its rounded lobes are gray and relatively unweathered. These color differences are brought out in the inset, enhanced at the upper right. In the false color image at the lower right, the shape of the visible-wavelength spectrum (related to the abundance of weathered ferric iron minerals) is indicated by the hue of the rocks. Blue indicates relatively unweathered rocks. Typical soils and drift, which are heavily weathered, are shown in green and flesh tones. The very red color in the creases in the rock surface correspond to a crust of ferric minerals. The origin of the rock is uncertain; the ferric crust may have grown underneath the rock, or it may cement pebbles together into a conglomerate. Ginger will be a target of future super-resolution studies to better constrain its origin.Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals.

    In the paper the result of elemental analysis by Nuclear Techniques of Coal and Embedded rocks samples from Vietnamese Quang Ninh and Thai Nguyen basins were presented. Methods used were: Neutron activation Analysis at Dalat Reactor, low counting with HP-Ge and NaJ detectors and X-ray fluorescent analysis with planar Si (Si) detector. Mean concentrations of 19 elements in coal and 9 in rocks were determined. Correlation between concentrations of elements were found. It appears that the correlation between ash content and U, K, Th, concentrations was poor for Quang Ninh antracitecoal. Correlation coefficient was found to be 0,63 for ash range 0-40%. Content of Th in anthracite Quang Ninh coal was much higher than reported in literature for subbituminous, bituminous and lignite coals, while Thai Nguyen fat coal contains considerable amount of Cu, Pb, Zn. Obtained data were useful for evaluation of potential hazard for environment from using coal as fuel for coal fired power plants, for estimation of possibility of using nuclear technique in coal industry in Vietnam. They could be used also for geochemical investigations. The simple of-line coal ash gauge basing on attenuation of soft gamma radiation from Fe-55 was also described.

    Active aging is central to enhancing the quality of life for older adults, but its conceptualization is not often made explicit for Asian elderly people. Little is known about active aging in older Thai adults, and there has been no development of scales to measure the expression of active aging attributes. The aim of this study was to develop a culturally relevant composite scale of active aging for Thai adults (AAS-Thai) and to evaluate its reliability and validity. EIGHT STEPS OF SCALE DEVELOPMENT WERE FOLLOWED: 1) using focus groups and in-depth interviews, 2) gathering input from existing studies, 3) developing preliminary quantitative measures, 4) reviewing for content validity by an expert panel, 5) conducting cognitive interviews, 6) pilot testing, 7) performing a nationwide survey, and 8) testing psychometric properties. In a nationwide survey, 500 subjects were randomly recruited using a stratified sampling technique. Statistical analyses included exploratory factor analysis, item analysis, and measures of internal consistency, concurrent validity, and test-retest reliability. Principal component factor analysis with varimax rotation resulted in a final 36-item scale consisting of seven factors of active aging: 1) being self-reliant, 2) being actively engaged with society, 3) developing spiritual wisdom, 4) building up financial security, 5) maintaining a healthy lifestyle, 6) engaging in active learning, and 7) strengthening family ties to ensure care in later life. These factors explained 69% of the total variance. Cronbach's alpha coefficient for the overall AAS-Thai was 0.95 and varied between 0.81 and 0.91 for the seven subscales. Concurrent validity and test-retest reliability were confirmed. The AAS-Thai demonstrated acceptable overall validity and reliability for measuring the multidimensional attributes of active aging in a Thai context. This newly developed instrument is ready for use as a screening tool to assess active aging levels among older

    Full Text Available Marine shells have been used as musical instruments in almost all parts of the world (Izikowitz 1935, including Mesoamerica, where large univalves, also called conch shells in the literature, had a utilitarian function as trumpets. Their use is well documented in most cultural areas of Mesoamerica, as in Western Mexico, through their various occurrences in archaeological contexts and museums collections.

    A general formalism for the dynamics of nonrotating cylindrical thin-shell wormholes is developed. The time evolution of the throat is explicitly obtained for thin-shell wormholes whose metric has the form associated with local cosmic strings. It is found that the throat collapses to zero radius, remains static, or expands forever, depending only on the sign of its initial velocity

    An Expert System Development (ESD) Shell design implementation is desribed in detail. The shell provides high-level generic facilities for Knowledge Representation (KR) and inferencing and tools for developing user interfaces. Powerful set of tools in the shell relieves much of the programming burden in the ES development. The shell is written in PROLOG under IBM PC/AT. KR facilities are based on two very powerful formalisms namely, frames and rules. Inference Engine (IE) draws most of its power from unification and backward reasoning strategy in PROLOG. This basic mechanism is enhanced further by incorporating both forward and backward chaining of rules and frame-based inferencing. Overall programming style integrates multiple paradigms including logic, object oriented, access-oriented and imperative programming. This permits ES designer a lot of flexibility in organizing inference control. Creation and maintainance of knowledge base is a major activity. The shell, therefore, provides number of facilities to simplify these tasks. Shell design also takes note of the fact that final success of any system depends on end-user satisfaction and hence provides features to build use-friendly interfaces. The shell also provides a set of interfacing predicates so that it can be embedded within any PROLOG program to incorporate functionalilty of the shell in the user program.

    The moderate-amplitude axisymmetric oscillations of an inviscid liquid shell surrounding an incompressible gas bubble are calculated by a multiple-time-scale expansion for initial deformations composed of two-lobed perturbations of the shell and a displacement of the bubble from the center of mass of the liquid. Two types of small-amplitude motion are identified and lead to very different nonlinear dynamic interactions, as described by the results valid up to second order in the amplitude of the initial deformation. In the ''bubble mode,'' the oscillations of the captive bubble and the liquid shell are exactly in phase and the bubble vibrates about its initial eccentric location. The bubble moves toward the center of the drop when the shell is perturbed into a ''sloshing mode'' of oscillation where both interfaces move out of phase. These results explain the centering of liquid shells observed in several experiments

    Full text: Background: Childhood obesity is one of the global malnutrition problem. To assess body composition, stable isotope has been widely used for total body water (TBW) and body fat assessments. In the year 2008, Thailand involved in the IAEA Technical Cooperation Project (TC project) which aimed to develop and validate tools for Thai children to assess obesity in 247 pre-adolescent children aged 8 to 10 years. Later in the year 2011, only 100 children were agreed to be tracked for their body composition assessment. Objective: To explore the changes of body composition and to compare the changes between gender in 3 years period. Materials and methods: A total of 100 children (49 boys and 51 girls), who involved the project in 2008 (P1) and later in 2011 (P2) were measured for their body composition. BMI for age using WHO 2007 cut off was used to identify their nutritional status. TBW was determined by deuterium oxide dilution technique. Fat-free mass (FFM) and fat mass (FM) were estimated. Results: Out of 100 children, 87 children (41 boys and 46 girls) provided the completed data of TBW at P1 and P2. They all grew up with significantly increased in weight, height, BMI (p<0.001). Their body composition in terms of %TBW, %FEM and %FM were not changed in both genders. Boys had significant higher %FFM than girls in P1 (71.5% in boys and 67.4% in girls, p<0.05) while %FM were significant lower than girls (28.5% in boys and 32.6% in girls, p<0.05). However, after 3 years, no significant different between boys and girls was observed. Over the 3 years period, based on BMI for age, the proportion of overweight and obese children increased from 36.6% to 48.8% for boys, and from 32.6% to 41.3% for girls. Around 17% of normal boys became overweight and obese, and for girls only 8.7% was found. Less than 5% of overweight and obese boys became normal, and none for girls. Conclusion: The obesity problem was inevitably increased when children are advance in age. However for

    The current study details the nuclear organization of the rock hyrax amygdaloid complex using both Nissl and myelin stains, along with a range of immunohistochemical stains. The rock hyrax appears to be the least derived of the Afrotherians, a group with a huge range of body phenotypes, life histories and specialized behaviours, brain sizes, and ecological niches. In this sense, the rock hyrax represents a species where the organization of the amygdaloid complex may be reflective of that in stem Eutherian mammals. Our analysis indicates that the nuclear organization of the rock hyrax amygdaloid complex is indeed very similar to that in other mammals studied, with four major nuclear groupings (the deep or basolateral group; the superficial or cortical-like or corticomedial group; the centromedial group; and the other amygdaloid nuclei) being observed, which is typical of Eutherian mammals. Moreover, each of these groupings is composed of several nuclei, the vast majority of which were readily identified in the rock hyrax. Small nuclei identified in rodents and primates were absent in the superficial and centromedial groups, seemingly involved with olfaction. A novel shell-like nucleus of the accessory basal nuclear cluster was observed in the rock hyrax, again, likely to be involved in olfaction. The current study underlines the conserved nature of nuclear parcellation in the Eutherian mammal amygdaloid complex and indicates that across most species, the flow of information processing related to species-specific affective-laden stimuli and the resultant physiological and behavioural outcomes are likely to be similar across species.

  17. Reflection of Confucianism, Hinduism, and Buddhism on gender relations and gender specific occupation in Thai society.

    It is posited that present-day Thai society is the product of different settlement patterns among Chinese Confucian followers and those ascribing to matrilocal practices. Chinese settled in urban areas and maintained Confucian dogma that barred women from high ranking positions and dictated a women's role of subservience to men. Matrilocal systems proliferated in rural areas. The village kinship system was egalitarian, until a class-state society was instituted and patriarchal systems dominated. At that time, women's status was reduced. Massive Chinese immigration occurred during the mid-19th century until World War II. Some Indians also migrated during this time period. The dominant use of the Thai language forced the Chinese to assimilate into Thai culture. Thai Buddhist practices were open and similar enough to Confucian ideology that religious assimilation also occurred. A small group of Chinese immigrants retained their ties to Chinese customs. The pattern of foreigners' involvement in the Thai economy was promoted by official policy. In the last several decades Thai policy shifted to an increasingly Thai-influenced economy. Other influences on gender patterns and Thai culture were the Hinduism of Indians who settled in Central Siam, the Mon aristocracy, and Brahmin cults. After the Khmers took over control of this region, the Indian caste system and the Hindu belief in Manu were integrated into Khmer culture. Women were considered the weaker and inferior sex and dependent upon men. The kings of Siam followed Brahmin rituals after the 15th century. Buddhism and the "sangha" became the central Thai religious institution. Even today Buddhist monks are given 3 months time off with pay for time spent as a monk, while maternity leave for women is limited to 45 days. The status of women is traced during the Sukothai period (1250-1350), the Ayudhaya period (1350-1767), and the Ratanakosin period (since 1782). Present occupational patterns reflect women's dominance in

    Due to the change of life style of people in developed and developing countries, there is an increased economic growth of prepared meals. In Thailand, there is a dynamic growth of market for chilled prepared meals because of the growth of food services in supermarkets and convenient stores. However, the shelf-life for ready-to-eat chilled food including chilled prepared meals is quite short and sometimes insufficient to meet market requirements and it is implicated in a number of serious foodborne disease outbreaks. Irradiation could provide a potential to improve the microbiological safety and extend the shelf-life of chilled prepared meals. Therefore, the study about the possibility to use irradiation for extending shelf-life and ensure microbiological safety of chilled prepared meals should be conducted. Also, information relevant to the application of food safety control system like Hazard Analysis and Critical Control Point (HACCP) should be gathered to ensure more safety of the irradiated prepared meals. Many traditional Thai dishes are popular in Thai restaurants over the world. Thai dishes are normally composed of herb and spicy with different types of meat. All dishes are eaten along with rice. Aromatic rice is the most preference for Thai consumers and foreigners. Thai spicy basil rice dish with selected meat such as chicken is selected as a prepared meal in this study due to its popularity and feasibility of commercial production.

    To investigate prospectively the type and rate of injuries sustained during amateur Muay Thai competition. Prospective cohort study collection of data following clinical examination. Amateur Muay Thai competitions in the United Kingdom organized by the International Amateur Muay Thai Federation. Amateur Muay Thai boxers. Both sexes. Lightweight to super heavyweight. There were 92 participants, 12 females and 82 males. The average age was 17.3 years, and the average previous number of bouts was 3.9. A total of 588.5 minutes of competition time was assessed during a total of 10 events. Injury rates were 1.3 injuries per 100 minutes of competition in the lightweight category, 2.25 per 100 minutes of competition in the middleweight category, 30 per 100 minutes of competition in the heavyweight category, and 2.54 per 100 minutes of competition in the super heavyweight category. Compared with other reported martial arts, the injury rates are higher in Muay Thai. The head was shown to be the most common site of injury in amateur fighters, but there was an almost complete absence of lower limb injuries, which again is at variance with reported figures for other martial arts.

    This study examines the Thai version of the Multidimensional Scale of Perceived Social Support (MSPSS) for its psychometric properties. In total 462 participants were recruited - 310 medical students from Chiang Mai University and 152 psychiatric patients, and they completed the Thai version of the MSPSS, the State Trait Anxiety Inventory (STAI), the Rosenberg Self-Esteem Scale (RSES) and the Thai Depression Inventory (TDI). Test-retest reliability was conducted over a four week period. Factor analysis produced three-factor solutions for both patient (PG) and student groups (SG), and overall the model demonstrated adequate fit indices. The mean total score and the sub-scale score for the SG were statistically higher than those in the PG, except for 'Significant Others'. The internal consistency of the scale was good, with a Cronbach's alpha of 0.91 for the SG and 0.87 for the PG. After a four week retest for reliability exercise, the intra-class correlation coefficient (ICC) was found to be 0.84. The Thai-MSPSS was found to have a negative correlation with the STAI and the TDI, but was positively correlated with the RSES. The Thai MSPSS is a reliable and valid instrument to use.

    To translate the 14-item Condom Self-Efficacy Scale (CSES) into Thai and to validate the Thai version of the Condom Self-efficacy Scale (CSES-T) among Thai adolescents and young adults. The CSES was translated using a back-translation technique and validated with a cluster-based sample of 425 participants aged 18 to 22 years from eight randomly selected private vocational schools in Bangkok. Participants completed anonymous self-administered scales. Principal component analysis with varimax rotation was conducted to identify latent factors. Factor analysis indicated three factors: communication, correct use, and consistent use. Items loading on the original CSES also loaded on the same factors of the CSES-T except one item. The Cronbach's alpha coefficients were .85 for the total scale, .70 for consistent use, .79 for correct use, and .80 for communication. Based on psychometric properties, the CSES-T is a valid and reliable tool. It is culturally appropriate for Thai young adults. Thai researchers and health care providers can use the CSES-T to assess adolescents' and young adults' self-efficacy to use condoms as well as to further develop and evaluate interventions to increase condom use.

    Full Text Available The rhomboid fossa of clavicle is used to determine the age and sex in anthropology and forensic sciences. The variant types of rhomboid fossa on inferior surface have been reported in many races except in Thais. This study therefore was aimed at classifying the types of the rhomboid fossa in Northeastern Thais. The identified 476 Northeastern Thais dried clavicles (270 males and 206 females were observed and recorded for the types of rhomboid fossa. The results showed that Thai-rhomboid fossa could be classified into 4 types: Type 1: smooth; Type 2: flat; Type 3: elevated; and Type 4: depressed, respectively. The incidences of rhomboid fossa were as follows: Type 1: 0.21%; Type 2: 19.75%; Type 3: 76.26%; and Type 4: 3.78%, respectively. Additionally, it was found that the percentage of Type 4 (11.84% was much greater than that of female (1.94% compared to other types. This incidence of rhomboid fossa types especially Type 4 may be a basic knowledge to be used in sex identification. The high incidence of rhomboid fossa in both sexes of Northeastern Thai clavicles was Type 3 (elevated type.

    Taste perception is influenced by several factors. However, the relation between taste perception and food culture is unclear. This study compared taste thresholds between populations with different food culture, i.e. Thai and Japanese. A matched case-control study was conducted in 168 adults (84 for each; aged between 50 and 90 years). The age, sex, systemic disease, medication, smoking, xerostomia, and oral hygiene of both groups were not different. Recognition thresholds (RTs) of sweet, salty, sour, bitter, and umami were measured using filter paper disc (FPD). Detection taste thresholds were measured using electrogustometry. Spicy preference was measured by calibrated questionnaires. Higher RTs of all tastes and higher detection taste thresholds were found in Thai as compared to those of Japanese (P differences between 2 countries. The average thresholds for sweet, salty, sour, and bitter in Thai and Japanese were 4 and 2, respectively. The average threshold for umami in Thai and Japanese was 5 and 3, respectively.

    This study aims to investigate the elemental compositions in 93 Thai rice samples using instrumental neutron activation analysis (INAA) and to identify rice according to their types and rice cultivars using statistical analysis. As, Mg, Cl, Al, Br, Mn, K, Rb and Zn in Thai jasmine rice and Sung Yod rice samples were successfully determined by INAA. The accuracy and precision of the INAA method were verified by SRM 1568a Rice Flour. All elements were found to be in a good agreement with the certified values. The precisions in term of %RSD were lower than 7%. The LODs were obtained in range of 0.01 to 29 mg kg-1. The concentration of 9 elements distributed in Thai rice samples was evaluated and used as chemical indicators to identify the type of rice samples. The result found that Mg, Cl, As, Br, Mn, K, Rb, and Zn concentrations in Thai jasmine rice samples are significantly different but there was no evidence that Al is significantly different from concentration in Sung Yod rice samples at 95% confidence interval. Our results may provide preliminary information for discrimination of rice samples and may be useful database of Thai rice.

    BACKGROUND Peripheral neuropathy is the most common complications of diabetic patients and leads to loss of plantar cutaneous sensation, movement perception, and body balance. Thai foot massage is an alternative therapy to improve balance. Therefore, the purpose of this study was to investigate the effects of Thai foot massage on balance performance in diabetic patients with peripheral neuropathy. MATERIAL AND METHODS Sixty patients with type-2 diabetes were recruited and randomly assigned into either the Thai foot massage or control groups. The Thai foot massage group received a modified Thai traditional foot massage for 30 min, 3 days per week for 2 weeks. We measured timed up and go (TUG), one leg stance: OLS), the range of motion (ROM) of the foot, and foot sensation (SWMT) before treatment, after the first single session, and after the 2-week treatment. RESULTS After the single treatment session, only the Thai foot massage group showed a significant improvement in TUG. After the 2-week treatment, both Thai foot massage and control groups showed a significant improvement of TUG and OLS (Pfoot massage group showed better improvement in TUG than the control group (pfoot massage group also showed significant improvements in ROM and SWMT after the 2-week treatment. CONCLUSIONS The results of this study suggest that Thai foot massage is a viable alternative treatment for balance performance, ROM of the foot, and the foot sensation in diabetic patients with peripheral neuropathy.

    The case is made for exempting geological specimens from the IAEA Regulations for Safer Transport of Radioactive Materials. It is pointed out that many mineral collectors in Devon and Cornwall may be unwittingly infringing these regulations by taking naturally radioactive rocks and specimens containing uranium ores. Even if these collectors are aware that these rocks are radioactive, and many are not, few have the necessary equipment to monitor the activity levels. If the transport regulations were to be enforced alarm could be generated and the regulations devalued in case of an accident. The danger from a spill of rock specimens is negligible compared with an accident involving industrial or medical radioactive substances yet would require similar special treatment. (UK)

    Full Text Available AbstractA major motivation of this study is to examine the factors that are the most important in contributing to the relatively poor efficiency performance of Thai manufacturing small and medium sized enterprises (SMEs. The results obtained will be significant in devising effective policies aimed at tackling this poor performance.This paper uses data on manufacturing SMEs in the North-eastern region of Thailand in 2007 as a case study, by applying a stochastic frontier analysis (SFA and a technical inefficiency effects model. The empirical results obtained indicate that the mean technical efficiency of all categories of manufacturing SMEs in theNorth-eastern region is 43%, implying that manufacturing SMEs have high levels of technical inefficiency in their production processes.Manufacturing SMEs in the North-eastern region are particularly labour-intensive. The empirical results of the technical inefficiency effects model suggest that skilled labour, the municipal area and ownership characteristics are important firm-specific factors affecting technical efficiency. The paper argues that the government should play a more substantial role in developing manufacturing SMEs in the North-eastern provinces through: providing training programs for employees and employers; encouraging a greater usage of capital and technology in the production process of SMEs; enhancing the efficiency of state-ownedenterprises; encouraging a wide range of ownership forms; and improving information and communications infrastructure.

  9. Changes in Thai sexual behavior lower HIV spread.

    1997-06-02

    More than 700,000 people are thought to be HIV positive in Thailand. A booming sex industry and social attitudes which support the male patronage of prostitutes are major factors in the spread of disease in the country. A 4-day workshop on sexual behavior and AIDS in Thailand was attended by representatives from Burma, Cambodia, China, Indonesia, Malaysia, the Philippines, Thailand, and Vietnam. According to the Joint UN Program on HIV/AIDS (UNAIDS), the percentage of military conscripts in northern Thailand who visited a brothel in the past year fell from 58% in 1991 to 23% in 1995, while the percentage of recruits using condoms during their most recent brothel visits increased from 60% to 90% over the same period. Statistics from the Thai Public Health Ministry indicate that the percentage of men in the general population who used condoms when visiting a brothel increased from 40% in 1990 to 90% in 1994. Furthermore, a nationwide survey among military conscripts found the prevalence of HIV infection fell from 3.7% in 1993 to 2.5% in 1995, with the downward trend continuing in 1996. This success in reducing the level of sexual risk behavior and the incidence of HIV infection in Thailand lends hope for the possibility of changing the course of the HIV/AIDS epidemic elsewhere.

    To investigate the knowledge and attitudes of Thai dental practitioners regarding patients with HIV, a cross-sectional study using self-administered questionnaires was conducted. The questionnaires requested demographic information and included questions evaluating the knowledge and attitude of dental practitioners towards HIV. The results were analyzed using Scheffe method for multiple comparisons at the 95 percent confidence level. Out of 1,200 questionnaires sent, 446 questionnaires were returned (response rate 37.2 percent). The subjects included final (sixth)-year dental students (11.9 percent), general dentists (29.1 percent), specialist dentists (15.5 percent), dental hygienists (30.5 percent), and dental assistants (13 percent). More than 80 percent of the dental practitioners correctly answered the questions testing their basic knowledge of HIV such as routes of transmission and common opportunistic infections. However, knowledge about HIV pathogenesis, complications, and advances in HIV management was lacking. Dental hygienists and dental assistants had statistically significant lower scores in knowledge about HIV than other groups. Sixty-seven percent of dental practitioners said they feel worried when treating patients with HIV, and 20.4 percent said they would deny treatment for patients with HIV if possible. While knowledge about HIV may be adequate among dental practitioners in Thailand, greater effort should be put into emphasizing positive attitudes towards patients with HIV.

    Full Text Available Thalassemia and hemoglobin E (Hb E are common in Thailand. Individuals with thalassemia trait usually have a normal hemoglobin concentration or mild anemia. Therefore, thalassemic individuals who have minimum acceptable Hb level may be accepted as blood donors. This study was aimed at determining the frequency of α-thalassemia 1 trait, β-thalassemia trait, and Hb E-related syndromes in Southern Thai blood donors. One hundred and sixteen voluntary blood donors, Southern Thailand origin, were recruited for thalassemia and Hb E screening by red blood cell indices/dichlorophenolindophenol precipitation test. β-Thalassemia and Hb E were then identified by high performance liquid chromatography and 4 common α-thalassemia deletions were characterized by a single tube-multiplex gap-polymerase chain reaction. Overall frequency of hemoglobinopathies was 12.9%, classified as follows: homozygous α-thalassemia 2 (1.7%, heterozygous α-thalassemia 1 (1.7%, heterozygous β-thalassemia without α-thalassemia (0.9%, heterozygous Hb E without α-thalassemia (5.2%, double heterozygotes for Hb E/α-thalassemia 1 (1.7%, homozygous Hb E without α-thalassemia (0.9%, and homozygous Hb E with heterozygous α-thalassemia 2 (0.9%. The usefulness of thalassemia screening is not only for receiving highly effective red blood cells in the recipients but also for encouraging the control and prevention program of thalassemia in blood donors.

    Over 50% of animal bites and potential rabies exposures in Thailand are in children and they also have the more severe injuries due to inexperience, smaller size and less ability to fend off attacks. Potential rabies exposures and animal bites are common in Thailand. Majority of these are in children where the extent of the injuries is also much more severe. The bitten areas correlate to the age of the children and level of the bitten animal head. These are areas noted for a higher risk of infection with rabies virus and shorter incubation periods. The vast majority of bites are due to dogs (86%) of which 74.6% are stray or community-owned animals. The prevalence of dog bites shows no seasonal variation in adults but there are two peaks during school vacation period for children. Extensive educational efforts directed at the Thai public are responsible for the rapid presentation of victims for post-exposure treatment. The dramatic reduction of human rabies deaths in Thailand during the last decades was achieved largely by the provision of expensive WHO standard post-exposure treatment, utilizing modern tissue culture vaccines and immunoglobulins. Canine and feline rabies is nevertheless still endemic and not likely to be controlled or eliminated till sustainable humane methods of dog population control and comprehensive countrywide canine rabies vaccination become possible through government policy.

    Full Text Available This paper presents an analysis of energy saving and changes in energy intensities in Thai manufacturing sector by Logarithmic Mean Divisia Index decomposition technique. This method includes three effects consists of the energy intensity effect, the structural effect and the effect of the economic growth on the energy consumption in Thailand by using the 25-year annual data from 1990 to 2014, carried out in four phases; (i before National Energy Conservation law, (ii during the effect of the law, (iii Transition period of the law from first to second version, and (iv during the effect of the law (No.2. We found that the most effective intensity effect is in the third phase due to the effect of the implementation of new energy efficient equipment from the second phase by enforcement of the law, especially in non-metallic sector, while the first phase illustrates the lowest intensity effect due to the energy conservation law had not been occurred. However, due to the highest economic growth of the country and change from agricultural to industrial development direction, the first phase presents the most effective structural effect, then this effect continuously decreased by time. We also conclude that the energy conservation law have direct effect to energy efficiency of the country however, strictly individual regulation which have target to enforce to energy intensive industries is still required for sustainable energy efficiency improvement.

    Various dermatological disorders and microbial skin infection can cause hyperpigmentation. Therefore, screenings for whitening and antimicrobial agents from Thai medicinal plants have been of research interest. Seventy-seven ethanol plant extracts were investigated for antityrosinase activity, eleven samples showed the tyrosinase inhibition more than 50 % were further preliminary screening for antimicrobial activity by agar disc diffusion and broth micro-dilution methods. Artocarpus integer (Thunb.) Merr. (Moraceae) root extract, which showed the potential of tyrosinase inhibition with 90.57 ± 2.93 % and antimicrobial activity against Staphylococcus aureus, S. epidermidis, Propionibacterium acnes and Trichophyton mentagophytes with inhibition zone as 9.10 ± 0.00, 10.67 ± 0.09, 15.25 ± 0.05 and 6.60 ± 0.17 mm, respectively was selected for phytochemical investigation. Three pure compounds were isolated as artocarpin, cudraflavone C and artocarpanone. And artocarpanone exhibited anti-tyrosinase effect; artocarpin and cudraflavone C also showed the potential of antibacterial activity against S. aureus, S. epidermidis and P. acnes with MIC at 2, 4 and 2 μg/ml, respectively and MBC at 32 μg/ml for these bacteria. So, these pure compounds are interesting for further study in order to provide possibilities of new whitening and antibacterial development. This will be the first report of phytochemical investigation of A. integer root.

    Ethyl acetate and methanol extracts of 18 Thai medicinal plants were investigated for their antibacterial activity against Propionibacterium acnes, Stapylococcus aureus, and S. epidermidis. Thirteen plant extracts were capable of inhibiting the growth of P. acnes and S. epidermidis, while 14 plant extracts exhibited an inhibitory effect on S. aureus. Based on the broth dilution method, the ethyl acetate extract of Alpinia galanga (L.) Wild. (Zingiberaceae) rhizome showed the strongest antibacterial effect against P. acnes, with minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values of 156.0 and 312.0 microg/mL, respectively. On the basis of bioassay-guided purification, the ethyl acetate extract was isolated to afford the antibacterial active compound, which was identified as 1'-acetoxychavicol acetate (1'-ACA). 1'-ACA had a strong inhibitory effect on P. acnes with MIC and MBC values of 62.0 and 250.0 microg/mL, respectively. Thus, 1'-ACA was used as an indicative marker for standardization of A. galanga extract using high performance liquid chromatography. These results suggest that A. galanga extract could be an interesting agent for further studies on an alternative treatment of acne.

    Childhood obesity is an emerging national health problem in Thailand. Our previous study found that one third of obese children and adolescents had impaired glucose tolerance (IGT) and 2.6 percent had already developed type 2 diabetes mellitus. An immediate strategy needs to be established in order to improve these metabolic problems. To determine whether diet and exercise education for lifestyle modification with or without metformin therapy in our diabetes clinic is enable to improve these metabolic problems. Twenty-six Thai obese children and adolescents with IGT, who received at least 6 months of treatment consisting of lifestyle modification alone or lifestyle modification and metformin (combined treatment) were enrolled into this study. Each patient underwent the second 2-hour oral glucose tolerance test (OGTT). Plasma glucose, insulin levels, HbA1C and lipid profiles were measured. The results were compared with historical pre-treatment data. Approximately 1 year after intervention, 19 out of 26 patients with IGT completed the second 2-hour OGTT. Sixteen patients (84.2%) successfully reversed to be normal glucose tolerance whereas 3 patients (15.8%) remained IGT. Body mass index (BMI), BMISDS, 2-hour plasma glucose, basal insulin level, 2-hour insulin level were significantly decreased after treatment in normal OGTT group (Ps youth is a reversible abnormality by lifestyle modification with or without metformin.

    This study was focused on determining Arsenic (As), Lead (Pb), Cadmium (Cd) and Zinc (Zn) in 33 indigenous plants and 12 soil in-situ plant samples in Thai Nguyen Province, Vietnam. The results showed that the soils of surveyed mining areas contained 181.2- 6754.3 mg kg(-1) As, 235.5-4337.2 mg kg(-1) Pb, 0.8- 419 mg kg(-1) Cd and 361.8-17565.1 mg kg(-1) Zn depending on the characteristics of each mining site. These values are much higher than those typical for normal soil. The heavy metal uptake into shoots and roots of 33 indigenous plant species was also determined. Two species of the plants investigated, Pteris vittata L. and Pityrogramma calomelanos L. were As hyperaccumulators, containing more than 0.1% heavy metals in their shoots. Eleusine indica L., Cynodon dactylon L., Cyperus rotundus L. and Equisetum ramosissimum (Vauch) accumulate very high Pb (0.15-0.65%) and Zn (0.22-1.56%) concentration in their roots. Additional experiments to clarify the potential of six these plants as good candidates for phytoremediation of heavy metal pollution soil are being carried out in our laboratory.

    2011-01-01

    MicroShell is a lightweight shell environment for engineers and software developers working with embedded microprocessors in Xilinx FPGAs. (MicroShell has also been successfully ported to run on ARM Cortex-M1 microprocessors in Actel ProASIC3 FPGAs, but without project-integration support.) Micro Shell decreases the time spent performing initial tests of field-programmable gate array (FPGA) designs, simplifies running customizable one-time-only experiments, and provides a familiar-feeling command-line interface. The program comes with a collection of useful functions and enables the designer to add an unlimited number of custom commands, which are callable from the command-line. The commands are parameterizable (using the C-based command-line parameter idiom), so the designer can use one function to exercise hardware with different values. Also, since many hardware peripherals instantiated in FPGAs have reasonably simple register-mapped I/O interfaces, the engineer can edit and view hardware parameter settings at any time without stopping the processor. MicroShell comes with a set of support scripts that interface seamlessly with Xilinx's EDK tool. Adding an instance of MicroShell to a project is as simple as marking a check box in a library configuration dialog box and specifying a software project directory. The support scripts then examine the hardware design, build design-specific functions, conditionally include processor-specific functions, and complete the compilation process. For code-size constrained designs, most of the stock functionality can be excluded from the compiled library. When all of the configurable options are removed from the binary, MicroShell has an unoptimized memory footprint of about 4.8 kB and a size-optimized footprint of about 2.3 kB. Since MicroShell allows unfettered access to all processor-accessible memory locations, it is possible to perform live patching on a running system. This can be useful, for instance, if a bug is

    Among the stress instruments that measure the degree to which life events are perceived as stressful, the Perceived Stress Scale (PSS) is widely used. The goal of this study was to examine the psychometric properties of a Thai version of the PSS-10 (T-PSS-10) with a clinical and non-clinical sample. Internal consistency, test-retest reliability, concurrent validity, and the factorial structure of the scale were tested. A total sample of 479 adult participants was recruited for the study: 368 medical students and 111 patients from two hospitals in Northern Thailand. The T-PSS-10 was used along with the Thai version of State Trait Anxiety Inventory (STAI), the Thai Version of the Rosenberg Self-Esteem Scale (RSES), and the Thai Depression Inventory (TDI). Exploratory Factor Analysis (EFA) yielded 2 factors with eigenvalues of 5.05 and 1.60, accounting for 66 percent of variance. Factor 1 consisted of 6 items representing "stress"; whereas Factor 2 consisted of 4 items representing "control". The item loadings ranged from 0.547 to 0.881. Investigation of the fit indices associated with Maximum Likelihood (ML) estimation revealed that the two-factor solution was adequate [chi2 = 35.035 (df = 26, N = 368, p reliability. The Thai version of the PSS-10 demonstrated excellent goodness-of-fit for the two factor solution model, as well as good reliability and validity for estimating the level of stress perception with a Thai population.

    Full Text Available Background/purpose: Many factors, including economic, psychosocial statuses and ethnicity, affect patients' decision to seek orthodontic treatment. The present study compared orthodontic patients' motivation, attitude and the factors affecting this motivation in Taiwanese and Thai patients. We investigated the association between the aforementioned variables and patient characteristics. Materials and methods: We enrolled 250 Thai and 250 Taiwanese patients (age ≥ 20 years from Sunprasitthiprasong and Taipei Medical University Hospitals, respectively, by using self-administered questionnaires. Demographic characteristics were analyzed using Pearson's chi-square test, patients' motivation, attitude and the factors affecting this motivation were analyzed using the sample t-test. The association among the variables was investigated by multiple regression analysis. Results: In both hospitals, the main motivation for seeking orthodontic treatment was esthetic concerns; the patients believed that treatment could make them more beautiful. Taiwanese and Thai patients rejected treatment because of high treatment costs and long treatment periods, respectively. A significant association was observed between household income and Thai patients' motivation (p < 0.05. Sex was significantly associated with Thai patients' attitude (p < 0.05. Age, sex, active treatment duration, and marital status were associated with Taiwanese attitude toward treatment (p < 0.05. In addition, age, household income, and information resources were significantly associated with the factors affecting Taiwanese patients' motivation (p < 0.05. Conclusion: Ethnicity influenced patients' motivation. Economic status was the main factor affecting Thai patients, whereas many factors affected Taiwanese patients' decision to seek orthodontic treatment. However, esthetic concerns were a crucial motivation for both groups. Keywords: factors affecting

    Full Text Available Abstract Background Among the stress instruments that measure the degree to which life events are perceived as stressful, the Perceived Stress Scale (PSS is widely used. The goal of this study was to examine the psychometric properties of a Thai version of the PSS-10 (T-PSS-10 with a clinical and non-clinical sample. Internal consistency, test-retest reliability, concurrent validity, and the factorial structure of the scale were tested. Methods A total sample of 479 adult participants was recruited for the study: 368 medical students and 111 patients from two hospitals in Northern Thailand. The T-PSS-10 was used along with the Thai version of State Trait Anxiety Inventory (STAI, the Thai Version of the Rosenberg Self-Esteem Scale (RSES, and the Thai Depression Inventory (TDI. Results Exploratory Factor Analysis (EFA yielded 2 factors with eigenvalues of 5.05 and 1.60, accounting for 66 percent of variance. Factor 1 consisted of 6 items representing "stress"; whereas Factor 2 consisted of 4 items representing "control". The item loadings ranged from 0.547 to 0.881. Investigation of the fit indices associated with Maximum Likelihood (ML estimation revealed that the two-factor solution was adequate [χ2 = 35.035 (df = 26, N = 368, p r = 0.60, p r = 0.55, p r = -0.46, p Conclusions The Thai version of the PSS-10 demonstrated excellent goodness-of-fit for the two factor solution model, as well as good reliability and validity for estimating the level of stress perception with a Thai population. Limitations of the study are discussed.

    2017-08-01

    Interest in the origin and evolution of the turtle shell has resulted in a most unlikely clade becoming an important research group for investigating morphological diversity in developmental biology. Many turtles generate a two-component shell that nearly surrounds the body in a bony exoskeleton. The ectoderm covering the shell produces epidermal scutes that form a phylogenetically stable pattern. In some lineages, the bones of the shell and their ectodermal covering become reduced or lost, and this is generally associated with different ecological habits. The similarity and diversity of turtles allows research into how changes in development create evolutionary novelty, interacting modules, and adaptive physiology and anatomy.

    Nineteen young Thai women were purposively selected from networks of nongovernmental organizations involving children and youths in Bangkok. Our grounded theory findings indicated that these young women used the basic social process they called "waiting for the right time" in order to maintain heterosexual abstinence. Waiting for the right time involved one overarching condition, honoring parental love, and included three overlapping properties: learning rules, planning life path, and ways of preserving virginity. The findings provide information that may lead to the development of culturally competent interventions for middle-class Thai youths to remain healthy and avoid pregnancy.

  10. Elastic Rock Heterogeneity Controls Brittle Rock Failure during Hydraulic Fracturing

    2014-12-01

    For interpretation and inversion of microseismic data it is important to understand, which properties of the reservoir rock control the occurrence probability of brittle rock failure and associated seismicity during hydraulic stimulation. This is especially important, when inverting for key properties like permeability and fracture conductivity. Although it became accepted that seismic events are triggered by fluid flow and the resulting perturbation of the stress field in the reservoir rock, the magnitude of stress perturbations, capable of triggering failure in rocks, can be highly variable. The controlling physical mechanism of this variability is still under discussion. We compare the occurrence of microseismic events at the Cotton Valley gas field to elastic rock heterogeneity, obtained from measurements along the treatment wells. The heterogeneity is characterized by scale invariant fluctuations of elastic properties. We observe that the elastic heterogeneity of the rock formation controls the occurrence of brittle failure. In particular, we find that the density of events is increasing with the Brittleness Index (BI) of the rock, which is defined as a combination of Young's modulus and Poisson's ratio. We evaluate the physical meaning of the BI. By applying geomechanical investigations we characterize the influence of fluctuating elastic properties in rocks on the probability of brittle rock failure. Our analysis is based on the computation of stress fluctuations caused by elastic heterogeneity of rocks. We find that elastic rock heterogeneity causes stress fluctuations of significant magnitude. Moreover, the stress changes necessary to open and reactivate fractures in rocks are strongly related to fluctuations of elastic moduli. Our analysis gives a physical explanation to the observed relation between elastic heterogeneity of the rock formation and the occurrence of brittle failure during hydraulic reservoir stimulations.

  12. Isogeometric shell formulation based on a classical shell model

    KAUST Repository

    Niemi, Antti

    2012-09-04

    This paper constitutes the first steps in our work concerning isogeometric shell analysis. An isogeometric shell model of the Reissner-Mindlin type is introduced and a study of its accuracy in the classical pinched cylinder benchmark problem presented. In contrast to earlier works [1,2,3,4], the formulation is based on a shell model where the displacement, strain and stress fields are defined in terms of a curvilinear coordinate system arising from the NURBS description of the shell middle surface. The isogeometric shell formulation is implemented using the PetIGA and igakit software packages developed by the authors. The igakit package is a Python package used to generate NURBS representations of geometries that can be utilised by the PetIGA finite element framework. The latter utilises data structures and routines of the portable, extensible toolkit for scientific computation (PETSc), [5,6]. The current shell implementation is valid for static, linear problems only, but the software package is well suited for future extensions to geometrically and materially nonlinear regime as well as to dynamic problems. The accuracy of the approach in the pinched cylinder benchmark problem and present comparisons against the h-version of the finite element method with bilinear elements. Quadratic, cubic and quartic NURBS discretizations are compared against the isoparametric bilinear discretization introduced in [7]. The results show that the quadratic and cubic NURBS approximations exhibit notably slower convergence under uniform mesh refinement as the thickness decreases but the quartic approximation converges relatively quickly within the standard variational framework. The authors future work is concerned with building an isogeometric finite element method for modelling nonlinear structural response of thin-walled shells undergoing large rigid-body motions. The aim is to use the model in a aeroelastic framework for the simulation of flapping wings.

  14. Creep buckling of shells

    International Nuclear Information System (INIS)

    Stone, C.M.; Nickell, R.E.

    1977-01-01

    Because of the characteristics of LMFBR primary piping components (thin-walled, low pressure, high temperature), the designer must guard against creep buckling as a potential failure mode for certain critical regions, such as elbows, where structural flexibility and inelastic response may combine to concentrate deformation and cause instability. The ASME Boiler and Pressure Vessel Code, through its elevated temperature Code Case 1592 (Section III, Division 1) provides design rules for Class 1 components aimed at preventing creep buckling during the design life. A similar set of rules is being developed for Class 2 and 3 components at this time. One of the original concepts behind the creep buckling rules was that the variability in creep properties (especially due to the effects of prior heat treatment), the uncertainty about initial imperfections, and the lack of confirmed accuracy of design analysis meant that conservatism would be difficult to assure. As a result, a factor of ten on service life was required (i.e. analysis must show that, under service conditions that extrapolate the life of the component by ten times, creep buckling does not occur). Two obvious problems with this approach are that: first, the creep behavior must also be extrapolated (since most creep experiments are terminated at a small fraction of the design life, extrapolation of creep data is already an issue, irrespective of the creep buckling question); second the nonlinear creep analysis, which is very nearly prohibitively expensive for design life histograms, becomes even more costly. Analytical results for an aluminum cylindrical shell subjected to axial loads at elevated temperatures are used to examine the supposed equivalence of two types of time-dependent buckling safety factors - a factor of ten on service life and a factor of 1.5 on loading

    Neosporosis has a worldwide distribution and causes economic losses in farming, particularly by increasing the risk of abortion in cattle. This study investigated the effects of Thai piperaceae (Piper betle, P. nigrum, and P. sarmentosum) extracts on Neospora caninum infections in vitro and in vivo. In an in vitro parasite growth assay based on the green fluorescent protein (GFP) signal, P. betle was the most effective extract at inhibiting parasite growth in human foreskin fibroblast cells (IC 50 of GFP-expressing N. caninum parasites, 22.1μg/ml). The P. betle extract, at 25μg per ml, inhibited parasite invasion into host cells. Furthermore, in two independent experiments, treating N. caninum-infected mice with the P. betle extract for 7days post-infection increased their survival. In trial one, the anti-N. caninum effects of the P. betle extract reduced the mouse clinical scores for 30days post-infection (dpi). The survival rate of the mice treated with 400mg/kg was 100% compared with 66.6% for those treated with 100mg/kg and the non-treated controls. In trial two, treating the infected mice with the P. betle extract increased their survival at 50dpi. All mice in the non-treatment group died; however, the survival rates of the 400mg/kg-treated and 100mg/kg-treated mice were 83.3% and 33.3%, respectively. Also, a trend towards a reduced parasite burden was noted in the brains of the P. betle extract-treated mice, compared with the control mice. Therefore P. betle extract has potential as a medicinal plant for treating neosporosis. Copyright © 2017 Elsevier B.V. All rights reserved.

    A cross-sectional study was conducted from June to December, 2003 among Thai Buddhist monks in 4 provinces of the central region (Nonthaburi, Pathum Thani, Saraburi and Chai Nat) and in 4 provinces of the eastern region (Chachoengsao, Rayong, Trat, and Sa Kaeo) of Thailand. Data were collected using face to face interviews, questionnaires, and physical examination reports (weight, height, heart rate, blood pressure, etc) as the research tools. This study focused on sociodemographics, history of illness, and smoking behavior. The proportion of the cigarette smoking was 47.6% of the total of 920 Buddhist monks. The age group 20-34 years, Maha Nikaya section and Public temple were the majority of the study subjects. Multivariate analysis revealed that only four factors were related to smoking consumption: dharma education, Naktharm To (grade 2) (OR = 0.6, 95% Cl: 0.4-0.9), Naktharm Aek (grade 3) or above (OR = 0.4, 95% Cl: 0.2-0.6); Lay education, secondary school (OR = 0.7, 95% Cl: 0.5-0.9), bachelor degree or above (OR = 0.4, 95% Cl: 0.2-0.8); systolic blood pressure > or = 140 mmHg (OR = 1.8, 95% Cl: 1.1-2.8) and history of respiratory illness (OR = 3.2, 95% Cl: 1.5-6.9). As a result, dharma education and well educated persons were the crucial factors which led to success in decreasing cigarette smoking. Smoking cessation campaigns and education of the consequences of smoking are strongly recommended among risk groups.

    Prognosis of cerebral venous sinus thrombosis (CVST) has never been studied in Thailand. A simple prognostic score to predict poor prognosis of CVST has also never been reported. The authors are aiming to establish a simple and reliable prognostic score for this condition. The medical records of CVST patients from eight neurological training centers in Thailand who received between April 1993 and September 2005 were reviewed as part of this retrospective study. Clinical features included headache, seizure, stroke risk factors, Glasgow coma scale (GCS), blood pressure on arrival, papilledema, hemiparesis, meningeal irritation sign, location of occluded venous sinuses, hemorrhagic infarction, cerebrospinal fluid opening pressure, treatment options, length of stay, and other complications were analyzed to determine the outcome using modified Rankin scale (mRS). Poor prognosis (defined as mRS of 3-6) was determined on the discharge date. One hundred ninety four patients' records, 127 females (65.5%) and mean age of 36.6 +/- 14.4 years, were analyzed Fifty-one patients (26.3%) were in the poor outcome group (mRS 3-6). Overall mortality was 8.4%. Univariate analysis and then multivariate analysis using SPSS version 11.5 revealed only four statistically significant predictors influencing outcome of CVST They were underlying malignancy, low GCS, presence of hemorrhagic infarction (for poor outcome), and involvement of lateral sinus (for good outcome). Thai venous stroke prognostic score (TV-SPSS) was derived from these four factors using a multiple logistic model. A simple and pragmatic prognostic score for CVST outcome has been developed with high sensitivity (93%), yet low specificity (33%). The next study should focus on the validation of this score in other prospective populations.

    The prevalence, gender distribution and clinical presentation of IBS differ between Asian and Western countries. This study aimed at studying and comparing enteroendocrine, Musashi 1 (Msi 1) and neurogenin 3 (neurog 3) cells in Thai and Norwegian IBS patients. Thirty Thai and 61 Norwegian IBS patients as well as 20 Thai and 24 Norwegian controls were included. Biopsy samples were taken from each of the sigmoid colon and the rectum during a standard colonoscopy. The samples were immunostained for serotonin, peptide YY, oxyntomodulin, pancreatic polypeptide, somatostatin, Msi 1 and neurog 3. The densities of immunoreactive cells were determined with computerized image analysis. The densities of several enteroendocrine cell types were altered in both the colon and rectum of both Thai and Norwegian IBS patients. Some of these changes were similar in Thai and Norwegian IBS patients, while others differed. The findings of abnormal densities of the enteroendocrine cells in Thai patients support the notion that enteroendocrine cells are involved in the pathophysiology of IBS. The present observations highlight that IBS differs in Asian and Western countries, and show that the changes in large-intestine enteroendocrine cells in Thai and Norwegian IBS patients might be caused by different mechanisms.

    2017-01-01

    As a typical failure phenomenon, rock burst occurs in many mines. It can not only cause the working face to cease production, but also cause serious damage to production equipment, and even result in casualties. To explore how to govern rock burst of working face under igneous rock, the 10416 working face in some mine is taken as engineering background. The supports damaged extensively and rock burst took place when the working face advanced. This paper establishes the mechanical model and conducts theoretical analysis and calculation to predict the fracture and migration mechanism and energy release of the thick hard igneous rock above the working face, and to obtain the advancing distance of the working face when the igneous rock fractures and critical value of the energy when rock burst occurs. Based on the specific conditions of the mine, this paper put forward three kinds of governance measures, which are borehole pressure relief, coal seam water injection and blasting pressure relief.

    1978-04-01

    Geologic and geochemical criteria were developed for the occurrence of economic uranium deposits in alkaline igneous rocks. A literature search, a limited chemical analytical program, and visits to three prominent alkaline-rock localities (Ilimaussaq, Greenland; Pocos de Caldas, Brazil; and Powderhorn, Colorado) were made to establish criteria to determine if a site had some uranium resource potential. From the literature, four alkaline-intrusive occurrences of differing character were identified as type-localities for uranium mineralization, and the important aspects of these localities were described. These characteristics were used to categorize and evaluate U.S. occurrences. The literature search disclosed 69 U.S. sites, encompassing nepheline syenite, alkaline granite, and carbonatite. It was possible to compare two-thirds of these sites to the type localities. A ranking system identified ten of the sites as most likely to have uranium resource potential

    Purpose: To convert radioactive wastes into the final state for storage (artificial rocks) in a short period of time. Method: Radioactive burnable wastes such as spent papers, cloths and oils and activated carbons are burnt into ashes in a burning furnace, while radioactive liquid wastes such as liquid wastes of boric acid, exhausted cleaning water and decontaminating liquid wastes are powderized in a drying furnace or calcining furnace. These powders are joined with silicates as such as white clay, silica and glass powder and a liquid alkali such as NaOH or Ca(OH) 2 and transferred to a solidifying vessel. Then, the vessel is set to a hydrothermal reactor, heated and pressurized, then taken out about 20 min after and tightly sealed. In this way, radioactive wastes are converted through the hydrothermal reactions into aqueous rock stable for a long period of time to obtain solidification products insoluble to water and with an extremely low leaching rate.

    Geologic and geochemical criteria were developed for the occurrence of economic uranium deposits in alkaline igneous rocks. A literature search, a limited chemical analytical program, and visits to three prominent alkaline-rock localities (Ilimaussaq, Greenland; Pocos de Caldas, Brazil; and Powderhorn, Colorado) were made to establish criteria to determine if a site had some uranium resource potential. From the literature, four alkaline-intrusive occurrences of differing character were identified as type-localities for uranium mineralization, and the important aspects of these localities were described. These characteristics were used to categorize and evaluate U.S. occurrences. The literature search disclosed 69 U.S. sites, encompassing nepheline syenite, alkaline granite, and carbonatite. It was possible to compare two-thirds of these sites to the type localities. A ranking system identified ten of the sites as most likely to have uranium resource potential.

  6. Rock and mineral magnetism

    1984-01-01

    The past two decades have witnessed a revolution in the earth sciences. The quantitative, instrument-based measurements and physical models of. geophysics, together with advances in technology, have radically transformed the way in which the Earth, and especially its crust, is described. The study of the magnetism of the rocks of the Earth's crust has played a major part in this transformation. Rocks, or more specifically their constituent magnetic minerals, can be regarded as a measuring instrument provided by nature, which can be employed in the service of the earth sciences. Thus magnetic minerals are a recording magnetometer; a goniometer or protractor, recording the directions of flows, fields and forces; a clock; a recording thermometer; a position recorder; astrain gauge; an instrument for geo­ logical surveying; a tracer in climatology and hydrology; a tool in petrology. No instrument is linear, or free from noise and systematic errors, and the performance of nature's instrument must be assessed and ...

    Results of the DBM and FEM analysis in this study indicate that a suitable rock mass for repository of radioactive waste should be moderately jointed (about 1 joint/m 2 ) and surrounded by shear zones of the first order. This allowes for a gentle and flexible deformation under tectonic stresses and prevent the development of large cross-cutting failures in the repository area. (author)

    The problems of statisfying similarity between a physical model and the prototype in rock wherein fissures and cracks place a role in physical behavior is explored. The need for models of large physical dimensions is explained but also testing of models of the same prototype over a wide range of scales is needed to ascertain the influence of lack of similitude of particular parameters between prototype and model. A large capacity centrifuge would be useful in that respect

    Mathematical models are the only way of examining the return of radioactivity from nuclear waste to the environment over long periods of time. Work in Britain has helped identify areas where more basic data is required, but initial results look very promising for final disposal of high level waste in hard rock repositories. A report by the National Radiological Protection Board of a recent study, is examined.

  11. Rock pushing and sampling under rocks on Mars

    Moore, H.J.; Liebes, S.; Crouch, D.S.; Clark, L.V.

    1978-01-01

    Viking Lander 2 acquired samples on Mars from beneath two rocks, where living organisms and organic molecules would be protected from ultraviolet radiation. Selection of rocks to be moved was based on scientific and engineering considerations, including rock size, rock shape, burial depth, and location in a sample field. Rock locations and topography were established using the computerized interactive video-stereophotogrammetric system and plotted on vertical profiles and in plan view. Sampler commands were developed and tested on Earth using a full-size lander and surface mock-up. The use of power by the sampler motor correlates with rock movements, which were by plowing, skidding, and rolling. Provenance of the samples was determined by measurements and interpretation of pictures and positions of the sampler arm. Analytical results demonstrate that the samples were, in fact, from beneath the rocks. Results from the Gas Chromatograph-Mass Spectrometer of the Molecular Analysis experiment and the Gas Exchange instrument of the Biology experiment indicate that more adsorbed(?) water occurs in samples under rocks than in samples exposed to the sun. This is consistent with terrestrial arid environments, where more moisture occurs in near-surface soil un- der rocks than in surrounding soil because the net heat flow is toward the soil beneath the rock and the rock cap inhibits evaporation. Inorganic analyses show that samples of soil from under the rocks have significantly less iron than soil exposed to the sun. The scientific significance of analyses of samples under the rocks is only partly evaluated, but some facts are clear. Detectable quantities of martian organic molecules were not found in the sample from under a rock by the Molecular Analysis experiment. The Biology experiments did not find definitive evidence for Earth-like living organisms in their sample. Significant amounts of adsorbed water may be present in the martian regolith.

    1994-01-01

    In 1989, UK Nirex began a programme of surface-based characterization of the geology and hydrogeology of a site at Sellafield to evaluate its suitability to host a deep repository for radioactive waste. The next major stage in site characterization will be the construction and operation of a Rock Characterization Facility (RCF). It will be designed to provide rock characterization information and scope for model validation to permit firmer assessment of long-term safety. It will also provide information needed to decide the detailed location, design and orientation of a repository and to inform repository construction methods. A three-phase programme is planned for the RCF. During each phase, testwork will steadily improve our geological, hydrogeological and geotechnical understanding of the site. The first phase will involve sinking two shafts. That will be preceded by the establishment of a network of monitoring boreholes to ensure that the impact of shaft sinking can be measured. This will provide valuable data for model validation. In phase two, initial galleries will be excavated, probably at a depth of 650 m below Ordnance datum, which will host a comprehensive suite of experiments. These galleries will be extended in phase three to permit access to most of the rock volume that would host the repository. (Author)

    Full Text Available The purpose of this article is to discuss the role of Rock in Rio: The Musical, as herald of megafestival Rock in Rio. Driven by the success that musicals have reached in Brazil, we believe that the design of this spectacle of music, dance and staging renews the brand of the rock festival, once it adds the force of young and healthy bodies to its concept. Moreover, the musical provides Rock in Rio with some distance from the controversal trilogy of sex, drugs and rock and roll, a strong mark of past festivals around the world. Thus, the musical expands the possibilities of growth for the brand.

    2017-01-01

    To study the extent of Internet addiction (IA) and its association with depression in Thai medical students. A cross-sectional study was conducted at Faculty of Medicine, Ramathibodi Hospital. Participants were first- to fifth-year medical students who agreed to participate in this study. Demographic characteristics and stress-related factors were derived from self-rated questionnaires. Depression was assessed using the Thai version of Patient Health Questionnaire (PHQ-9). A total score of five or greater derived from the Thai version of Young Diagnostic Questionnaire for Internet Addiction was classified as "possible IA". Then chi-square test and logistic regression were used to evaluate the associations between possible IA, depression and associated factors. From 705 participants, 24.4% had possible IA and 28.8% had depression. There was statistically significant association between possible IA and depression (odds ratio (OR) 1.92, 95% confidence interval (CI): 1.34-2.77, P-value depression in possible IA group was 1.58 times of the group of normal Internet use (95% CI: 1.04-2.38, P-value = 0.031). Academic problems were found to be a significant predictor of both possible IA and depression. IA was likely to be a common psychiatric problem among Thai medical students. The research has also shown that possible IA was associated with depression and academic problems. We suggest that surveillance of IA should be considered in medical schools.

    1981-06-01

    The relations between educational research, policy, planning and implementation in Thailand are the topic of this paper. The major focus is on the research/policy linkage. A complex educational administrative structure and a pluralistic informal power structure characterize the Thai research context. A tetrahedral model of linkages provides the conceptual framework for the analysis. Details are then provided with respect to the actual operationalization of the model in terms of the Thai approach in practice. Major elements in the Thai approach include the use of expert policy committees, joint committees involving both administrators and researchers, problem-oriented seminars, and commissioned research. Actual examples of research efforts described are an educational reform study, local level school mapping, a school cluster experiment, a budget exercise to improve the equity of primary school resource allocations, and a policy evaluation of sub-district secondary schools. Finally, lessons to be learned from the Thai experience are summarized. Thailand has experienced some success in building analytical educational research capacity and ensuring its utilization. Key elements in this success have been an emphasis on strengthening human capacities; judging political will in a timely, flexible manner; creatively utilizing bureaucratic forms such as committees; and remaining both politically detached and sensitive.

    2013-06-01

    To develop a model of healthy aging from the perspective of Thais, a grounded theory approach, including in-depth interviews and focus groups, was used. A purposive sample of 39 community-dwelling adults aged 40-85 years old was interviewed. The Thai healthy aging model composed of three themes: normality, nature, and dharma. In Thai, they are called tham-ma-da, tham-ma-chat, and tham-ma, or "Thai 3Ts". The theme of normality encompasses subthemes of staying physically active by being involved in plenty of physical activities, and being mentally active with creative and thoughtful hobbies and work. The theme of nature encompasses subthemes of living simply and being careful with money. The theme of dharma encompasses subthemes of enjoyment through helping family and participating in community activities, staying away from stress and worries by talking openly and honestly with someone, making merit, and helping other people without expecting anything in return. A greater understanding of healthy aging is a benefit for older adults and healthcare providers in an intervention-design process. Research can contribute valuable information to shape policy for healthy aging as well. © 2013 Wiley Publishing Asia Pty Ltd.

  8. The Experience Economy in Thai Hotels and Resort Clusters: The Role of Authentic Food

    Directory of Open Access Journals (Sweden)

    Thanan Apivantanaporn

    2013-04-01

    Full Text Available Although hotels and other tourist institutions in Thailand have been making some sporadic attempts to incorporate specifically Thai food and beverage (F&B elements into their overall product offering, this has rarely been attempted in a thoughtful and systematic manner. This is despite the importance of F&B in determining overall levels of customer satisfaction and the recent importance attached to incorporating ‘Thainess’ into the hotel and tourism industry nationwide. It is, therefore, rather surprising that little if any sustained effort has been made to define authenticity with respect to Thai food (bearing in mind also regional variations or to incorporate certificates of quality to establishments providing such authentic dishes. This paper draws on qualitative research and personal observation undertaken in a wide range of Thai hotels with a view to identifying emergent value-adding clusters in the domestic hospitality sector. It describes and categorizes the uses of Thai F&B currently and identifies shortcomings in industry vision, which leads to recommendations for both hotel and resort managers and also to those responsible for national level tourism development efforts. The paper also recognizes the problematic nature of the concepts of ‘authenticity’ in this context and attempts to reconcile differing conceptions.

    2013-03-01

    Graphic symbols are a vital part of most augmentative and alternative communication systems. Communication fluency of graphic symbol user depends on how well the relationship between symbols and its referents are learnt. The first aim of this study is to survey the perception of the selected graphic symbols across seven age groups of participants with different educational background. Sixty-five individuals identified themselves as Thai and ranged in age from 10 to 50 years participated in the investigation used 64 graphic symbols. The last aim of this study is to demonstrate the analysis of multimeaning graphic symbols, which will be used in Thai Picture-based communication system. The twenty graphic symbols with 9-14 meanings are analyzed in both syntactic and semantic aspects. The meanings are divided into five categories: noun, verb/adjective, size, color and shape. Respect to the first aim, the results suggest that the participants under investigation with different sexes, age groups, as well as various educational levels perceive the features or inherent characteristics of such graphic symbols similarly. The results of the analysis of multimeaning of graphic symbols indicate that the foundation of Minspeak, polysemy and redundancy of the words illustrates the inherit meanings of the real-life objects, and it also conveys that the Thai graphic symbols are influenced by numerous factors in Thai circumstance such as ability, motivation, experience, worldview and culture.

  11. Forensic Applicability of Femur Subtrochanteric Shape to Ancestry Assessment in Thai and White American Males.

    Science.gov (United States)

    Tallman, Sean D; Winburn, Allysha P

    2015-09-01

    Ancestry assessment from the postcranial skeleton presents a significant challenge to forensic anthropologists. However, metric dimensions of the femur subtrochanteric region are believed to distinguish between individuals of Asian and non-Asian descent. This study tests the discriminatory power of subtrochanteric shape using modern samples of 128 Thai and 77 White American males. Results indicate that the samples' platymeric index distributions are significantly different (p≤0.001), with the Thai platymeric index range generally lower and the White American range generally higher. While the application of ancestry assessment methods developed from Native American subtrochanteric data results in low correct classification rates for the Thai sample (50.8-57.8%), adapting these methods to the current samples leads to better classification. The Thai data may be more useful in forensic analysis than previously published subtrochanteric data derived from Native American samples. Adapting methods to include appropriate geographic and contemporaneous populations increases the accuracy of femur subtrochanteric ancestry methods. © 2015 American Academy of Forensic Sciences.

    Energy Technology Data Exchange (ETDEWEB)

    Eichhammer, W.; Gruber, E.; Cremer, C.

    2000-06-01

    In 1992 the Thai Government passed the Energy Conservation Promotion (ECP) Act to improve energy efficiency in Thai industry and commerce. The Thai-German Energy Efficiency Promotion Project (ENEP) is supporting the Department of Energy Development and Promotion (DEDP) in its effort to implement the Energy Conservation Program for large buildings and designated factories. About 4000 buildings and factories under the Compulsory Program, have to report every 6 months their energy consumption data to DEDP. Every 3 years energy audits have to be conducted by registered energy consultants, to identify energy saving opportunities, to set saving targets and to recommend energy conservation measures. Investments in energy efficient technologies are subsidized from an Energy Conservation Fund. Data from the energy consumption reports and the energy audit reports are collected in DEDP's database for further processing. The database is structured according to the Thai Standard Industrial Classification. In order to exploit the wealth of information provided by the auditing procedure the objective of the present work carried out by the consultant FhG-ISI for DEDP/BERC on behalf of the German Gesellschaft fuer Technische Zusammenarbeit (GTZ) was to recommend an appropriate set of energy efficiency indicators. This indicator set should allow DEDP to extract from the energy consumption reports, energy audit reports and other sources, useful statistical information to monitor and improve energy efficiency in Thailand.

    2015-07-01

    Cultural or ethnic factors may play an important role in subjects' pain reports. The aim of the study was to compare the prevalence of orofacial pain symptoms between Finnish and Thai populations. The Finnish study population comprised the Northern Finland Birth Cohort 1966, of which 5696 subjects participated in the present study. The Thai sample consisted of 1501 randomly selected people living in 10 different districts in Bangkok. Data on orofacial pain was collected based on questionnaires. After adjusting for age, gender and education, the logistic regression analysis showed that Thai subjects had an increased risk for reporting oral pain (OR = 4.5, 95% CI = 3.7-5.4), tooth pain (OR = 2.0, 95% CI = 1.8-2.4) and pain in the face (OR = 1.5, 95% CI = 1.2-1.7). It can be concluded that Thai people report more orofacial pain symptoms than Finnish subjects. Cross-cultural factors exist in the background of reporting pain symptoms in the oral and facial area.

    To study the association of the butyrylcholinesterase K variant (BChE-K) and the plasma BChE activity with mild cognitive impairment (MCI) in Thai community-dwelling patients. One hundred patients diagnosed with MCI and 100 control subjects were recruited from the community-dwelling setting in Bangkok, Thailand. The genotype and allele distributions of the BChE-K were determined by polymerase chain reaction and subsequent DNA sequencing. The BChE activity was measured in plasma according to the Ellman's method. The BChE-K allele frequencies in the Thai community-dwelling patients were in accordance with other ethnics. The BChE-K allele frequency in the control subjects (12%) was higher than that of MCI patients (5.5%), suggesting a protective role of BChE-K for MCI in the Thai community-dwelling patients. The BChE-K homozygotes were significantly associated with lower BChE activity. Our results suggested that the BChE-K may be implicated as a protective factor for MCI in the Thai community-dwelling patients, although a further study with a large sample size is warranted to confirm this.

    The authors report on their work to produce a foam shell target for two possible applications: (1) as liquid-layered cryogenic target on Omega Upgrade, and (2) as a back-up design for the NIF. This target consists of a roughly 1 mm diameter and 100 μm thick spherical low-density foam shell surrounding a central void. The foam will be slightly overfilled with liquid D 2 or DT, the overfilled excess being symmetrically distributed on the inside of the shell and supported by thermal gradient techniques. The outside of the foam is overcoated with full density polymer which must be topologically smooth. The technology for manufacturing this style of foam shell involves microencapsulation techniques and has been developed by the Japanese at ILE. Their goal is to determine whether this technology can be successfully adapted to meet US ICF objectives. To this end a program of foam shell development has been initiated at LLNL in collaboration with both the General Atomics DOE Target Fabrication Contract Corporation and the Target Fabrication Group at LLE

  10. The evolution of mollusc shells.

    2018-05-01

    Molluscan shells are externally fabricated by specialized epithelial cells on the dorsal mantle. Although a conserved set of regulatory genes appears to underlie specification of mantle progenitor cells, the genes that contribute to the formation of the mature shell are incredibly diverse. Recent comparative analyses of mantle transcriptomes and shell proteomes of gastropods and bivalves are consistent with shell diversity being underpinned by a rapidly evolving mantle secretome (suite of genes expressed in the mantle that encode secreted proteins) that is the product of (a) high rates of gene co-option into and loss from the mantle gene regulatory network, and (b) the rapid evolution of coding sequences, particular those encoding repetitive low complexity domains. Outside a few conserved genes, such as carbonic anhydrase, a so-called "biomineralization toolkit" has yet to be discovered. Despite this, a common suite of protein domains, which are often associated with the extracellular matrix and immunity, appear to have been independently and often uniquely co-opted into the mantle secretomes of different species. The evolvability of the mantle secretome provides a molecular explanation for the evolution and diversity of molluscan shells. These genomic processes are likely to underlie the evolution of other animal biominerals, including coral and echinoderm skeletons.

    2015-01-01

    The present article contains a review of the literatures on the creep buckling of shell structures published from late 1950's to recent years. In this article, the creep buckling studies on circular cylindrical shells, spherical shells, partial cylindrical shells and other shells are reviewed in addition to creep buckling criteria. Creep buckling is categorized into two types. One is the creep buckling due to quasi-static instability, in which the critical time for creep buckling is determined by tracing a creep deformation versus time curve. The other is the creep buckling due to kinetic instability, in which the critical time can be determined by examining the shape of total potential energy in the vicinity of a quasi-static equilibrium state. Bifurcation buckling and snap-through buckling during creep deformation belong to this type of creep buckling. A few detailed descriptions are given to the bifurcation and snap-through type of creep buckling based on the present authors' works. (author)

    A reactor for the synthesis of gold nanoparticles is one of the uses of a poly(styrene)-block-poly(2-vinylpyridine)-block-poly(ethylene oxide) triblock copolymer (PS-b-P2VP-b-PEO) which forms core-shell-corona micelles in water. Very low polydispersity spherical micelles are observed that consist of a PS core surrounded by a pH-sensitive P2VP shell and a corona of PEO chains end-capped by a hydroxyl group. The corona can act as a site for attaching responsive or sensing molecules. © 2001 WILEY-VCH Verlag GmbH, Weinheim, Fed. Rep. of Germany.

  13. Femoral hip prosthesis design for Thais using multi-objective shape optimization

    2015-01-01

    Highlights: • A multi-objective shape optimization was proposed to design hip prosthesis for Thais. • The prosthesis design was optimized in terms of safety of both cement and prosthesis. • The objective functions used the Soderberg fatigue strength formulations. • Safety factors of the cement and prosthesis are 1.200 and 1.109 respectively. • The newly designed prosthesis also fits well with chosen small-sized Thai femurs. - Abstract: The long-term success of Total Hip Arthroplasty (THA) depends largely on how well the prosthetic components fit the bones. The majority of cemented femoral hip prosthesis failures are due to aseptic loosening, which is possibly caused by cracking of the cement mantle. The strength of cement components is a function of cement mantles having adequate thickness. Since the size and shape of cemented femoral hip prostheses used in Thailand are based on designs for a Caucasian population, they do not properly conform to most Thai patients’ physical requirements. For these reasons, prostheses designed specifically for Thai patients must consider the longevity and functionality of both cement and prosthesis. The objective of this study was to discover a new design for femoral hip prostheses which is not only optimal and safe in terms of both cement and prosthesis, but also fits the selected Thai femur. This study used a small-sized Thai femoral model as a reference model for a new design. Biocompatible stainless steel 316L (SS316L) and polymethylmethacrylate (PMMA) were selected as raw materials for the prosthesis and bone cement respectively. A multi-objective shape optimization program, which is an interface between optimization C program named NSGA-II and a finite element program named ANSYS, was used to optimize longevity of femoral hip prostheses by varying shape parameters at assigned cross-sections of the selected geometry. Maximum walking loads of sixty-kilograms were applied to a finite element model for stress and

    When foundation base rocks are deeper than the level of installing structures or there exist weathered rocks and crushed rocks in a part of base rocks, often sound artificial base rocks are made by substituting the part with concrete. But in the construction of Kashiwazaki Kariwa Nuclear Power Station of Tokyo Electric Power Co., Inc., the foundation base rocks consist of mudstone, and the stiffness of concrete is large as compared with the surrounding base rocks. As the quality of the substituting material, the nearly same stiffness as that of the surrounding soft rocks and long term stability are suitable, and the excellent workability and economical efficiency are required, therefore, artificial soft rocks were developed. As the substituting material, the soil mortar that can obtain the physical property values in stable form, which are similar to those of Nishiyama mudstone, was selected. The mechanism of its hardening and the long term stability, and the manufacturing plant are reported. As for its application to the base rocks of Kashiwazaki Kariwa Nuclear Power Station, the verification test at the site and the application to the base rocks for No. 7 plant reactor building and other places are described.

    1999-11-01

    It is crucial to evaluate the hydrogeological characteristics of rock in Japan in order to assess the performance of geosphere. This report summarizes the hydrogeological characteristics of various rock types obtained from broad literature surveys and the fields experiments at the Kamaishi mine in northern Japan and at the Tono mine in central Japan. It is found that the hydraulic conductivity of rock mass ranges from 10 -9 m/s to 10 -8 m/s, whereas the hydraulic conductivity of fault zone ranges from 10 -9 m/s to 10 -3 m/s. It is also found that the hydraulic conductivity tends to decrease with depth. Therefore, the hydraulic conductivity of rock mass at the depth of a repository will be smaller than above values. From the investigations at outcrops and galleries throughout the country, fractures are observed as potential pathways in all rock types. All kinds of crystalline rocks and pre-Neogene sedimentary rocks are classified as fractured media where fracture flow is dominant. Among these rocks, granitic rock is considered the archetype fractured media. On the other hand, andesite, tuff and Neogene sedimentary rocks are considered as intermediate between fractured media and porous media where flow in fractures as well as in rock matrix are significant.

    Dominant thermogravimetric signatures related to lignin were observed in cashew shell as compared to these signatures in cashew shell cake. The phenomenon of weakening of lignin from cashew shell to cashew shell cake was explained on the basis of changes in the activation energies. The pertinent temperature regimes responsible for the release of different constituents of both the bio-materials were identified and compared. The activation energies of cashew shell and cashew shell cake were compared using Kissinger-Akahira-Sunose method. Thermogravimetric profiling of cashew shell and cashew shell cake indicated that these were different kinds of bio-materials. Copyright © 2013 Elsevier Ltd. All rights reserved.

  17. Grinding into Soft, Powdery Rock

    This hole in a rock dubbed 'Clovis' is the deepest hole drilled so far in any rock on Mars. NASA's Mars Exploration Rover Spirit captured this view with its microscopic imager on martian sol 217 (Aug. 12, 2004) after drilling 8.9 millimeters (0.35 inch) into the rock with its rock abrasion tool. The view is a mosaic of four frames taken by the microscopic imager. The hole is 4.5 centimeters (1.8 inches) in diameter. Clovis is key to a developing story about environmental change on Mars, not only because it is among the softest rocks encountered so far in Gusev Crater, but also because it contains mineral alterations that extend relatively deep beneath its surface. In fact, as evidenced by its fairly crumbly texture, it is possibly the most highly altered volcanic rock ever studied on Mars. Scientific analysis shows that the rock contains higher levels of the elements sulfur, chlorine, and bromine than are normally encountered in basaltic rocks, such as a rock dubbed 'Humphrey' that Spirit encountered two months after arriving on Mars. Humphrey showed elevated levels of sulfur, chlorine, and bromine only in the outermost 2 millimeters (less than 0.1 inch) of its surface. Clovis shows elevated levels of the same elements along with the associated softness of the rock within a borehole that is 4 times as deep. Scientists hope to compare Clovis to other, less-altered rocks in the vicinity to assess what sort of water-based processes altered the rock. Hypotheses include transport of sulfur, chlorine, and bromine in water vapor in volcanic gases; hydrothermal circulation (flow of volcanically heated water through rock); or saturation in a briny soup containing the same elements. In this image, very fine-grained material from the rock has clumped together by electrostatic attraction and fallen into the borehole. NASA/JPL/Cornell/USGS

    Muay Thai is a martial art that requires complex skills and tactical excellence for success. However, the energy demand during a Muay Thai competition has never been studied. This study was devised to obtain an understanding of the physiological capacities underlying Muay Thai performance. To that end, the aerobic energy expenditure and the recruitment of anaerobic metabolism were assessed in 10 male athletes during a simulation match of Muay Thai. Subjects were studied while wearing a portable gas analyzer, which was able to provide data on oxygen uptake, carbon dioxide production, and heart rate (HR). The excess of CO2 production (CO2 excess) was also measured to obtain an index of anaerobic glycolysis. During the match, group energy expenditure was, on average (mean +/- standard error of the mean), 10.75 +/- 1.58 kcal.min-1, corresponding to 9.39 +/- 1.38 metabolic equivalents. Oxygen uptake and HRs were always above the level of the anaerobic threshold assessed in a preliminary incremental test. CO2 excess showed an abrupt increase in the first round, and reached a value of 636 +/- 66.5 mL.min-1. This parameter then gradually decreased throughout the simulation match. These data suggest that Muay Thai is a physically demanding activity with great involvement of both the aerobic metabolism and anaerobic glycolysis. In particular, it appears that, after an initial burst of anaerobic glycolysis, there was a progressive increase in the aerobic energy supply. Thus, training protocols should include exercises that train both aerobic and anaerobic energetic pathways.

    Thai females injecting drugs are ensnared in a web of problems arising from forms of prejudice that magnify their vulnerability. They are vulnerable, at risk, and exposed to a high degree of social suffering. This paper aims to elucidate how social production and structural violence combine to shape the lives of these women. Using a qualitative methodology, two focus groups with 5 key informants and in-depth interviews involving a total of 35 women injecting drugs were conducted in Bangkok. The findings reveal that the structural environment that directly impacts upon these women's lives becomes the reason for their suffering. The structural environment puts these women at risk of violence in numerous social settings in which these women engage as well as generating tension at a subjective level (i.e. the habitus) of these women. Thai female injecting drug users are trapped in a difficult tension between the demands for being Thai women seeking to exist in the masculine world of drug use but at the same time meeting Thai society's expectations of womanhood. Unequal gender relations are manifest in the everyday violence that women face in the drug community, culminating in the essential nature of women being questioned, undermined and threatened. Living in the drug community, women are subjected to violence and harassment, and gendered brutality by intimate partners. In conclusion, the social suffering that Thai female injecting drug users find themselves confronting is confined to dilemmas cause by tensions between drug use and the overriding gender habitus.

    This study aimed to determine human neutrophil antigen (HNA) frequency, estimate possible HNA incompatibilities and predict the risk of HNA alloimmunisation in the Northeastern Thai, Burmese and Karen populations. Alloantibodies against HNA are implicated in a number of clinical conditions, including immune-mediated neutropenia and transfusion reactions. A total of 400 unrelated healthy Thais, 261 Burmese and 249 Karen was included in this study. DNA samples were typed for HNA-1, -3, -4 and -5 systems using polymerase chain reactions with sequence-specific primers (PCR-SSP). In this cohort, HNA-1a was more prevalent than HNA-1b. Accordingly, the possible risk of HNA-1a alloimmunisation against HNA-1a is lower than HNA-1b (0·0802-0·1351 vs 0·2293-0·2497). This is in contrast to the situation reported in Caucasian and African populations. The predicted risk of HNA-3 incompatibility in Thais, Burmese and Karen were 28·09%, 30·66% and 22·77%, respectively. The possible risks of HNA-3a alloimmunisation were 0·0493 in Thais, 0·0608 in Burmese and 0·0196 in Karen, respectively. No individuals were found to be homozygous for HNA-4bb. The probability of developing alloantibodies against HNA-4a was low in these populations and every population in Asia. In contrast, the overall frequency of HNA-5bb homozygous individuals was high in this study, peaking at 0·192. This is the first study that reported the allele frequencies of HNA-1, -3, -4, and -5 in a large sample of healthy unrelated individuals from ethnic Thais, Burmese and Karen. Our results indicated the high possible risk of HNA-1, -3 and -5 alloimmunisation in these populations. © 2017 British Blood Transfusion Society.

    We review quantum Monte Carlo methods for dealing with large shell model problems. These methods reduce the imaginary-time many-body evolution operator to a coherent superposition of one-body evolutions in fluctuating one-body fields; the resultant path integral is evaluated stochastically. We first discuss the motivation, formalism, and implementation of such Shell Model Monte Carlo (SMMC) methods. There then follows a sampler of results and insights obtained from a number of applications. These include the ground state and thermal properties of pf-shell nuclei, the thermal and rotational behavior of rare-earth and γ-soft nuclei, and the calculation of double beta-decay matrix elements. Finally, prospects for further progress in such calculations are discussed. (orig.)

  3. Cask for concrete shells transportation

    2001-01-01

    Nowadays, nuclear plant radioactive waste are conditioned in situ into concrete shells. Most of them enter in the industrial waste category defined by the regulations of radioactive material transportation. However, the content of a few ones exceeds the limits set for low specific activity substances. Thus, these shells must be transported into type B packagings. To this end, Robatel has undertaken, for EDF (Electricite de France), the development of a container, named ROBATEL TM R68, for further licensing. The particularity of this packaging is that the lid must have a wide opening to allow the usual handling operations of the concrete shells. This leads to a non-conventional conception, and makes the package more vulnerable to drop test solicitations. In order to define a minimal drop test program on a reduced scale model, we use a simple method to find the most damageable drop angle. (author)

    2014-01-01

    Background Human enterovirus 71 (EV71) is an important pathogen caused large outbreaks in Asian-Pacific region with severe neurological complications and may lead to death in young children. Understanding of the etiological spectrum and epidemic changes of enterovirus and population’s immunity against EV71 are crucial for the implementation of future therapeutic and prophylactic intervention. Results A total of 1,182 patients who presented with the symptoms of hand foot and mouth disease (67.3%) or herpangina (HA) (16.7%) and admitted to the hospitals during 2008-2013 were tested for enterovirus using pan-enterovirus PCR targeting 5′-untranslated region and specific PCR for viral capsid protein 1 gene. Overall, 59.7% were pan-enterovirus positive comprising 9.1% EV71 and 31.2% coxsackievirus species A (CV-A) including 70.5% CV-A6, 27.6% CV-A16, 1.1% CV-A10, and 0.8% CV-A5. HFMD and HA occurred endemically during 2008-2011. The number of cases increased dramatically in June 2012 with the percentage of the recently emerged CV-A6 significantly rose to 28.4%. Co-circulation between different EV71 genotypes was observed during the outbreak. Total of 161 sera obtained from healthy individuals were tested for neutralizing antibodies (NAb) against EV71 subgenotype B5 (EV71-B5) using microneutralization assay. The seropositive rate of EV71-B5 was 65.8%. The age-adjusted seroprevalence for individuals was found to be lowest in children aged >6 months to 2 years (42.5%). The seropositive rate remained relatively low in preschool children aged > 2 years to 6 years (48.3%) and thereafter increased sharply to more than 80% in individuals aged > 6 years. Conclusions This study describes longitudinal data reflecting changing patterns of enterovirus prevalence over 6 years and demonstrates high seroprevalences of EV71-B5 NAb among Thai individuals. The rate of EV71 seropositive increased with age but without gender-specific significant difference. We identified

    1981-09-01

    The mined geologic burial of high level nuclear waste is now the favored option for disposal. The US National Waste Terminal Storage Program designed to achieve this disposal includes an extensive rock mechanics component related to the design of the wastes repositories. The plan currently considers five candidate rock types. This paper deals with the three hard rocks among them: basalt, granite, and tuff. Their behavior is governed by geological discontinuities. Salt and shale, which exhibit behavior closer to that of a continuum, are not considered here. This paper discusses both the generic rock mechanics R and D, which are required for repository design, as well as examples of projects related to hard rock waste storage. The examples include programs in basalt (Hanford/Washington), in granitic rocks (Climax/Nevada Test Site, Idaho Springs/Colorado, Pinawa/Canada, Oracle/Arizona, and Stripa/Sweden), and in tuff

Indirect stress measurements using overcoring methods with BGR-probes and CSIR-triaxial cells as well as direct stress measurements using the hydraulic-fracturing method were made. To determine in-situ rock deformation behavior borehole deformation tests, using a BGR-dilatometer, were performed. Two types of the BGR-probe were applied: a four-component-probe to determine horizontal stresses and a five-component-probe to determine a quasi three-dimensional stress field. The first time a computer for data processing was installed in the borehole together with the BGR-probe. Laboratory tests on low cylinders were made to study the stress-deformation behavior. To validate and to interprete the measurement results some test methods were modelled using the finite-element method. The dilatometer-tests yielded high values of Young's modulus, whereas laboratory tests showed lower values with a distinct deformation anisotropy. Stress measurements with the BGR-probe yielded horizontal stresses being higher than the theoretical overburden pressure. These results are comparable to the results of the hydraulic fracturing tests, whereas stresses obtained with CSIR-triaxial cells are lower. The detailed geological mapping of the borehole indicated relationships between stress and geology. With regard to borehole depth different zones of rock structure joint frequency, joint orientation, and orientation of microfissures as well as stress magnitude, stress direction, and degree of deformation anisotropy could be distinguished.

  11. Wave Function Engineering in CdSe/PbS Core/Shell Quantum Dots.

    The synthesis of epitaxial CdSe/PbS core/shell quantum dots (QDs) is reported. The PbS shell grows in a rock salt structure on the zinc blende CdSe core, thereby creating a crystal structure mismatch through additive growth. Absorption and photoluminescence (PL) band edge features shift to lower energies with increasing shell thickness, but remain above the CdSe bulk band gap. Nevertheless, the profiles of the absorption spectra vary with shell growth, indicating that the overlap of the electron and hole wave functions is changing significantly. This leads to over an order of magnitude reduction of absorption near the band gap and a large, tunable energy shift, of up to 550 meV, between the onset of strong absorption and the band edge PL. While the bulk valence and conduction bands adopt an inverse type-I alignment, the observed spectroscopic behavior is consistent with a transition between quasi-type-I and quasi-type-II behavior depending on shell thickness. Three effective mass approximation models support this hypothesis and suggest that the large difference in effective masses between the core and shell results in hole localization in the CdSe core and a delocalization of the electron across the entire QD. These results show the tuning of wave functions and transition energies in CdSe/PbS nanoheterostructures with prospects for use in optoelectronic devices for luminescent solar concentration or multiexciton generation.

    Full Text Available Research treats about producing activated carbons for CO2 capture from hazelnut shells (HN, walnut shells (WN and peanut shells (PN. Saturated solution of KOH was used as an activating agent in ratio 1:1. Samples were carbonized in the furnace in the range of temperatures 600°C–900°C. Properties of carbons were tested by N2 adsorption method, using BET equation, DFT method and volumetric CO2 adsorption method. With the increase of carbonization temperature specific surface area of studied samples increased. The largest surface area was calculated for samples carbonized at 900°C and the highest values of CO2 adsorption had samples: PN900 at 0°C (5.5 mmol/g and WN900 at 25°C (4.34 mmol/g. All of the samples had a well-developed microporous structure.

    1979-08-01

    Nonlinear theory of elastic shells is developed which incorporates both geometric and physical nonlinearities and which does not make use of the well known Love-Kirchhoff hypothesis. The resulting equations are formulated in tensorial notation and are reduced to the ones of common use when simplifying assumptions encountered in the especific litterature are taken. (Author) [pt

  19. Shell energy scenarios to 2050

    International Nuclear Information System (INIS)

    2008-01-01

    Shell developed two scenarios that describe alternative ways the energy future may develop. In the first scenario (Scramble) policymakers pay little attention to more efficient energy use until supplies are tight. Likewise, greenhouse gas emissions are not seriously addressed until there are major climate shocks. In the second scenario (Blueprints) growing local actions begin to address the challenges of economic development, energy security and environmental pollution. A price is applied to a critical mass of emissions giving a huge stimulus to the development of clean energy technologies, such as carbon dioxide capture and storage, and energy efficiency measures. The result is far lower carbon dioxide emissions. Both these scenarios can help Shell to test their strategy against a range of possible developments over the long-term. However, according to Shell, the Blueprints' outcomes offer the best hope for a sustainable future, whether or not they arise exactly in the way described. However, with the right combination of policy, technology and commitment from governments, industry and society globally, Shell believes it can be realized. But achieving the targets will not be easy, and time is short. Clear thinking, huge investment, and effective leadership are required

  20. Collapse analysis of toroidal shell

    International Nuclear Information System (INIS)

    Pomares, R.J.

    1990-01-01

    This paper describes a study performed to determine the collapse characteristics of a toroidal shell using finite element method (FEM) analysis. The study also included free drop testing of a quarter scale prototype to verify the analytical results. The full sized toroidal shell has a 24-inch toroidal diameter with a 24-inch tubal diameter. The shell material is type 304 strainless steel. The toroidal shell is part of the GE Model 2000 transportation packaging, and acts as an energy absorbing device. The analyses performed were on a full sized and quarter scaled models. The finite element program used in all analyses was the LIBRA code. The analytical procedure used both the elasto-plastic and large displacement options within the code. The loading applied in the analyses corresponded to an impact of an infinite rigid plane oriented normal to the drop direction vector. The application of the loading continued incrementally until the work performed by the deforming structure equalled the kinetic energy developed in the free fall. The comparison of analysis and test results showed a good correlation

  1. A smart rock

    Science.gov (United States)

    Pressel, Phil

    2014-12-01

    This project was to design and build a protective weapon for a group of associations that believed in aliens and UFO's. They collected enough contributions from societies and individuals to be able to sponsor and totally fund the design, fabrication and testing of this equipment. The location of this facility is classified. It also eventually was redesigned by the Quartus Engineering Company for use at a major amusement park as a "shoot at targets facility." The challenge of this project was to design a "smart rock," namely an infrared bullet (the size of a gallon can of paint) that could be shot from the ground to intercept a UFO or any incoming suspicious item heading towards the earth. Some of the challenges to design this weapon were to feed cryogenic helium at 5 degrees Kelvin from an inair environment through a unique rotary coupling and air-vacuum seal while spinning the bullet at 1500 rpm and maintain its dynamic stability (wobble) about its spin axis to less than 10 micro-radians (2 arc seconds) while it operated in a vacuum. Precision optics monitored the dynamic motion of the "smart rock."

  2. Rock critics as 'Mouldy Modernists'

    Directory of Open Access Journals (Sweden)

    Becky Shepherd

    2011-08-01

    Full Text Available Contemporary rock criticism appears to be firmly tied to the past. The specialist music press valorise rock music of the 1960s and 1970s, and new emerging artists are championed for their ‘retro’ sounding music by journalists who compare the sound of these new artists with those included in the established ‘canon’ of rock music. This article examines the narrative tropes of authenticity and nostalgia that frame the retrospective focus of this contemporary rock writing, and most significantly, the maintenance of the rock canon within contemporary popular culture. The article concludes by suggesting that while contemporary rock criticism is predominately characterised by nostalgia, this nostalgia is not simply a passive romanticism of the past. Rather, this nostalgia fuels a process of active recontextualisation within contemporary popular culture.

  3. What are the health needs, familial and social problems of Thai migrants in a local community in Australia? A focus group study.

    Vatcharavongvan, Pasitpon; Hepworth, Julie; Lim, Joanne; Marley, John

    2014-02-01

    This study explored the health needs, familial and social problems of Thai migrants in a local community in Brisbane, Australia. Five focus groups with Thai migrants were conducted. The qualitative data were examined using thematic content analysis that is specifically designed for focus group analysis. Four themes were identified: (1) positive experiences in Australia, (2) physical health problems, (3) mental health problems, and (4) familial and social health problems. This study revealed key health needs related to chronic disease and mental health, major barriers to health service use, such as language skills, and facilitating factors, such as the Thai Temple. We concluded that because the health needs, familial and social problems of Thai migrants were complex and culture bound, the development of health and community services for Thai migrants needs to take account of the ways in which Thai culture both negatively impacts health and offer positive solutions to problems.

    2018-04-27

    Background: Breast cancer screening programme is seen as the best practice to detect breast cancer early. However, there are circumstances that can prevent immigrant women from attending screening programmes. Little is known about Thai migrants and the barriers to their seeking breast cancer screening when living in a new homeland. This paper aimed to discuss the barriers to attending screening services among Thai migrant women living in Australia. Methods: This study adopted qualitative approach. Semi-structured in-depth interviewing and drawing methods were employed as data collection technique with 25 Thai migrant women who had not experienced breast cancer and were living in Metropolitan Melbourne, Australia. Thematic analysis method was employed to analyse the data. Results: Basing on the Health Belief Model, most Thai migrant women did not perceive that they were at risk of breast cancer. Despite seeing a breast cancer screening programme as important, the women rarely paid attention to breast cancer screening and used the mammography services provided by the Australian health care system. The barriers included the location of the services, unfamiliar patterns of health care provision, and language difficulties. Conclusions: There are many barriers that that they encountered in Australia that prevent Thai migrant women living in Melbourne Australia to pay attention to mammographic screening service provided by Australia health system. Our findings suggest that health services and interventions need to be designed more sensitive to the needs and socio-cultural context of migrant women in general and Thai migrant women in particular.

    2007-08-01

    Full text: Electron spin resonance (ESR) dating was conducted for some ungulate tooth enamel samples and shell fossils of the the Tham Lod rock shelter Area I (S23W10) located in Highland Archaeology Project in Pang Mapha District, Mae Hong Son Province, Thailand. Age estimation for wave-induced breaching of the cavity and initial sand deposition (Level 19-29) was 33,200 - 18,700 years and 32,300 years for teeth enamel and the shell fossils of Nodularia scobinata sp. (Carditidae) respectively. ESR spectra showed g-factor g1 (gll, gcenter) = 2.0030 - 2.0036, g2 = 2.0040 - 2.0041 and g3 (g?) = 1.997 - 1.9988 formed by CO2- orthorhombic free radical for teeth enamel and g-factor (gcenter) = 2.0042 + 0.0003 formed by SO3- free radical for fresh shell fossils

  13. Extensions to a nonlinear finite-element axisymmetric shell model based on Reissner's shell theory

    International Nuclear Information System (INIS)

    Cook, W.A.

    1981-01-01

    Extensions to shell analysis not usually associated with shell theory are described in this paper. These extensions involve thick shells, nonlinear materials, a linear normal stress approximation, and a changing shell thickness. A finite element shell-of-revolution model has been developed to analyze nuclear material shipping containers under severe impact conditions. To establish the limits for this shell model, the basic assumptions used in its development were studied; these are listed in this paper. Several extensions were evident from the study of these limits: a thick shell, a plastic hinge, and a linear normal stress

    HOOS was developed as an extension of the Western Ontario and McMaster Universities' Osteoarthritis Index questionnaire for measuring symptoms and functional limitations related to the hip(s) of patients with osteoarthritis. To determine the validity and reliability of the Thai version of the Hip disability and Osteoarthritis Outcome Score (HOOS) vis-à-vis hip osteoarthritis, the original HOOS was translated into a Thai version of HOOS, according to international recommendations. Patients with hip osteoarthritis (n = 57; 25 males) were asked to complete the Thai version of HOOS twice: once then again after a 3-week interval. The test-retest reliability was analyzed using the intraclass correlation coefficient (ICC). Internal consistencies were analyzed using Cronbach's alpha, while the construct validity was tested by comparing the Thai HOOS with the Thai modified SF-36 and calculating the Spearman's rank correlation coefficients. The Thai HOOS produced good reliability (i.e., the ICC was greater than 0.9 in all five subscales). All of the Cronbach's alpha showed that the Thai HOOS had high internal consistency (Cronbach's alpha greater than 0.8), especially for the pain and ADL subscales (0.89 and 0.90, respectively). The Spearman's rank correlation for all five subscales of the Thai HOOS had moderate correlation with the Bodily Pain subscale of the Thai SF-36. The pain subscale of the Thai HOOS had a high correlation with the Vitality and Social Function subscales of the Thai SF-36 (r = 0.55 and 0.54)-with which the symptom subscale had a moderate correlation. The Thai version of HOOS had excellent internal consistency, excellent test-retest reliability, and good construct validity. It can be used as a reliable tool for assessing quality of life for patients with hip osteoarthritis in Thailand.

  16. STRATEGY IMPLEMENTATION STYLES OF MALAYSIAN, THAI AND HUNGARIAN MIDDLE MANAGERS

    Directory of Open Access Journals (Sweden)

    Maheshkumar P. Joshi

    2004-01-01

    Full Text Available There is a need for more comparative empirical research that examines middle manager roles in strategic change. This paper reports a study of middle managers in two dynamic settings: the Asia/Pacific region – Malaysia and Thailand; and Central/Eastern Europe – Hungary. Results of 213 respondents across three countries indicate that middle managers from all three tend toward use of authoritarian management styles even in proactive strategic change situations. However, Hungarians are less likely to use these styles than Thai and Malaysian middle managers. For all three countries, managers with less work experience were found to have lower tendencies to use an authoritarian style of implementation. When top managers exhibit an aggressive strategic posture, middle-managers from all three countries are also less likely to use an authoritarian style.Firms that want to stay competitive in the global market place must continuously evolve by successfully accomplishing strategic change (Struckman & Yammarino 2003. Although senior managers are critical in leading the strategic change process, even the best-planned strategic changes will not achieve their full potential unless they are well implemented. Part of the strategic leadership responsibility, therefore, includes establishing a climate in which the organization's rank and file will experience both a positive attitude about change and the confidence to actively seek change opportunities (Kanter 2003. Research attention is bringing more insight into the important roles of middle-managers in this process of implementing strategic change (Balogun & Jenkins 2003; Floyd & Wooldridge, 1992, 1994; Wooldridge & Floyd 1990. Although there is little doubt that active support by middle managers is critical for the strategies to be well implemented (Guth & MacMillan 1986, there remain many important questions with regard to how middle managers participate in this process (Balogun 2003.The need for research

  17. Rock.XML - Towards a library of rock physics models

    2016-08-01

    Rock physics modelling provides tools for correlating physical properties of rocks and their constituents to the geophysical observations we measure on a larger scale. Many different theoretical and empirical models exist, to cover the range of different types of rocks. However, upon reviewing these, we see that they are all built around a few main concepts. Based on this observation, we propose a format for digitally storing the specifications for rock physics models which we have named Rock.XML. It does not only contain data about the various constituents, but also the theories and how they are used to combine these building blocks to make a representative model for a particular rock. The format is based on the Extensible Markup Language XML, making it flexible enough to handle complex models as well as scalable towards extending it with new theories and models. This technology has great advantages as far as documenting and exchanging models in an unambiguous way between people and between software. Rock.XML can become a platform for creating a library of rock physics models; making them more accessible to everyone.

    2005-05-01

    Physicists have used nuclear magnetic resonance to investigate the destructive effects of the crystallization of salt. Salt-weathering is one of the main causes of rock disintegration in nature, particularly in deserts, polar regions and along coastlines. However, it is also a very widespread cause of damage to man-made constructions. Bridges, for example, are attacked by de-icing salts, and cities such as Bahrain, Abu Dhabi and Adelaide are affected by rising damp from high ground-water levels. Indeed, many examples of cultural heritage, including the Islamic sites of Bokhara and Petra in Jordan and the Sphinx in Egypt, may ultimately be destroyed due to the effects of salt-weathering. Now Lourens Rijniers and colleagues at Eindhoven University in the Netherlands have developed a way to observe the solubility of various salts inside porous materials directly (Phys. Rev. Lett. 94 075503). (U.K.)

    Lindstrom, D. J.; Haskin, L. A.

    1979-01-01

    Electrolysis of silicate melts has been shown to be an effective means of producing metals from common silicate materials. No fluxing agents need be added to the melts. From solution in melts of diopside (CaMgSi2O6) composition, the elements Si, Ti, Ni, and Fe have been reduced to their metallic states. Platinum is a satisfactory anode material, but other cathode materials are needed. Electrolysis of compositional analogs of lunar rocks initially produces iron metal at the cathode and oxygen gas at the anode. Utilizing mainly heat and electricity which are readily available from sunlight, direct electrolysis is capable of producing useful metals from common feedstocks without the need for expendable chemicals. This simple process and the products obtained from it deserve further study for use in materials processing in space.

    Sahoo, Sarmila

    2017-01-01

    This book focuses on the free vibrations of graphite-epoxy laminated composite stiffened shells with cutout both in terms of the natural frequencies and mode shapes. The dynamic analysis of shell structures, which may have complex geometry and arbitrary loading and boundary conditions, is solved efficiently by the finite element method, even including cutouts in shells. The results may be readily used by practicing engineers dealing with stiffened composite shells with cutouts. Several shell forms viz. cylindrical shell, hypar shell, conoidal shell, spherical shell, saddle shell, hyperbolic paraboloidal shell and elliptic paraboloidal shell are considered in the book. The dynamic characteristics of stiffened composite shells with cutout are described in terms of the natural frequency and mode shapes. The size of the cutouts and their positions with respect to the shell centre are varied for different edge constraints of cross-ply and angle-ply laminated composite shells. The effects of these parametric variat...

  2. Preliminary results of consequence assessment of a hypothetical severe accident using Thai meteorological data

    2017-06-01

    Consequence assessment of a hypothetical severe accident is one of the important elements of the risk assessment of a nuclear power plant. It is widely known that the meteorological conditions can significantly influence the outcomes of such assessment, since it determines the results of the calculation of the radionuclide environmental transport. This study aims to assess the impacts of the meteorological conditions to the results of the consequence assessment. The consequence assessment code, OSCAAR, of Japan Atomic Energy Agency (JAEA) is used for the assessment. The results of the consequence assessment using Thai meteorological data are compared with those using Japanese meteorological data. The Thai case has following characteristics. Low wind speed made the radionuclides concentrate at the center comparing to the Japanese case. The squalls induced the peaks in the ground concentration distribution. The evacuated land is larger than the Japanese case though the relocated land is smaller, which is attributed to the concentration of the radionuclides near the release point.

  3. Use of model analysis to analyse Thai students’ attitudes and approaches to physics problem solving

    Rakkapao, S.; Prasitpong, S.

    2018-03-01

    This study applies the model analysis technique to explore the distribution of Thai students’ attitudes and approaches to physics problem solving and how those attitudes and approaches change as a result of different experiences in physics learning. We administered the Attitudes and Approaches to Problem Solving (AAPS) survey to over 700 Thai university students from five different levels, namely students entering science, first-year science students, and second-, third- and fourth-year physics students. We found that their inferred mental states were generally mixed. The largest gap between physics experts and all levels of the students was about the role of equations and formulas in physics problem solving, and in views towards difficult problems. Most participants of all levels believed that being able to handle the mathematics is the most important part of physics problem solving. Most students’ views did not change even though they gained experiences in physics learning.

    Full Text Available In Asia, voluntary intention to leave within the information technology sector is reaching epidemic proportions. In multiple ASEAN countries, HR professionals have stated that information technology professional ‘job hopping’ has become a culture with the cost to productivity and the corporate bottom line becoming enormous. The researchers have therefore undertaken a study to investigate the variables affecting Thai Information technology professionals’ intention to leave. Simple random sampling will be used to gather data through self-administrated questionnaires from an anticipated total of 340 respondents comprising IT managers, executives, and HR managers so as to study how work exhaustion, job satisfaction, and organizational commitment affect intention to leave. The importance of the study is significant as Thailand’s ICT market accounts for 11 percent of GDP and is the largest in Southeast Asia, with Thai government plans to make the Kingdom the hub for ASEAN’s new $US2.5 trillion GDP digital economy.

    The purpose of this study was to discover and describe the meanings and expressions of cultural care of a group of Thai immigrants in Sweden. Participants included 15 key informants and 24 general informants living in and around the town of Uppsala. The conceptual framework was provided by Leininger's theory of cultural care diversity and universality. Use was made of the ethnonursing method and the Sunrise Model in the search for multiple and related dimensions that influenced the generic and professional care practices of the Thai immigrants. Four major themes were formulated. Thus, care (a) means family and kinship relationships as expressed in daily life, (b) is expressed in traditional gender roles, (c) means religious beliefs as expressed in the Buddhist worship, and (d) means support of traditional health care practices. These themes support the cultural care theory and also confirm the Sunrise Model.

    Full Text Available Common problems of Thai nurses are low quality of life, working long hours, and a high turnover rate. The workload imbalance among nurses also worsens the turnover rate. With careful schedule planning, nurses do not have to work in consecutive shifts and can rest more. We interviewed and collected data from an emergency department at a hospital administered by a Thai university, related to objectives and constraints of monthly nurse scheduling, and actual monthly schedules. A multi-objective mathematical model was developed using the open source “OpenSolver” software in MS-Excel for nurse schedulers to freely use. We tested the model using actual data collected from the department and found that the schedules created by the model tended to provide more balanced workloads and more days off compared to the schedules created manually by a real scheduler. The model also suggested an easy policy to increase the number of nurses for future expansion.

    A pilot study was conducted to determine effects of an empowerment intervention on antiretroviral therapy (ART) adherence among Thai youth living with HIV/AIDS. It compared two groups of 23 young persons (15-24 years) who receive ART from AIDS clinics at two community hospitals. One hospital's patients served as the experimental group, and the other as a control group. The experimental groups attended five sessions that empowered them to take control of their own health. The control group received the standard of care. The data were analyzed using descriptive statistics and Chi-square statistics. Before the empowerment, no one from the experimental group or the control group had ART adherence ≥ 95%. After the intervention, the 82.6% of the experimental group had ≥ 95% adherence compared to the control group, which had 21.7% adherence (p < .0001). The empowerment intervention resulted in a significant increase in ART adherence among Thai youth.

    Kamcharean, Chanwit; Wattanakasiwich, Pornrat

    The objective of this study was to diagnose misconceptions of Thai and Lao students in thermodynamics by using a two-tier multiple-choice test. Two-tier multiple choice questions consist of the first tier, a content-based question and the second tier, a reasoning-based question. Data of student understanding was collected by using 10 two-tier multiple-choice questions. Thai participants were the first-year students (N = 57) taking a fundamental physics course at Chiang Mai University in 2012. Lao participants were high school students in Grade 11 (N = 57) and Grade 12 (N = 83) at Muengnern high school in Xayaboury province, Lao PDR. As results, most students answered content-tier questions correctly but chose incorrect answers for reason-tier questions. When further investigating their incorrect reasons, we found similar misconceptions as reported in previous studies such as incorrectly relating pressure with temperature when presenting with multiple variables.

    The next generation of exploration mission human systems will require environmental protection such as radiation protection that is effective and efficient. In order to continue human exploration, habitat systems will require special shells to protect astronauts from hostile environments. The Pressure Shell Approach to integrated environmental (radiation) protection is a multi-layer shell that can be used for multifunctional environmental protection. Self-healing, self-repairing nano technologies and sensors are incorporated into the shell. This shell consists of multiple layers that can be tailored for specific environmental protection needs. Mainly, this innovation focuses on protecting crew from exposure to micrometeorites, thermal, solar flares, and galactic cosmic ray (GCR) radiation. The Pressure Shell Approach consists of a micrometeoroid and secondary ejecta protection layer; a thin, composite shell placed in between two layers that is non-structural; an open cavity layer that can be filled with water, regolith, or polyethylene foam; a thicker composite shell that is a structural load bearing that is placed between two layers; and a bladder coating on the interior composite shell. This multi-layer shell creates an effective radiation protection system. Most of its layers can be designed with the materials necessary for specific environments. In situ materials such as water or regolith can be added to the shell design for supplemental radiation protection.

    Viking's soil sampler collector arm successfully pushed a rock on the surface of Mars during the afternoon of Friday, October 8. The irregular-shaped rock was pushed several inches by the Lander's collector arm, which displaced the rock to the left of its original position, leaving it cocked slightly upward. Photographs and other information verified the successful rock push. Photo at left shows the soil sampler's collector head pushing against the rock, named 'Mister Badger' by flight controllers. Photo at right shows the displaced rock and the depression whence it came. Part of the soil displacement was caused by the collector s backhoe. A soil sample will be taken from the site Monday night, October 11. It will then be delivered to Viking s organic chemistry instrument for a series of analyses during the next few weeks. The sample is being sought from beneath a rock because scientists believe that, if there are life forms on Mars, they may seek rocks as shelter from the Sun s intense ultraviolet radiation.

  13. Indentation of Ellipsoidal and Cylindrical Elastic Shells

    KAUST Repository

    2012-10-01

    Thin shells are found in nature at scales ranging from viruses to hens\\' eggs; the stiffness of such shells is essential for their function. We present the results of numerical simulations and theoretical analyses for the indentation of ellipsoidal and cylindrical elastic shells, considering both pressurized and unpressurized shells. We provide a theoretical foundation for the experimental findings of Lazarus etal. [following paper, Phys. Rev. Lett. 109, 144301 (2012)PRLTAO0031-9007] and for previous work inferring the turgor pressure of bacteria from measurements of their indentation stiffness; we also identify a new regime at large indentation. We show that the indentation stiffness of convex shells is dominated by either the mean or Gaussian curvature of the shell depending on the pressurization and indentation depth. Our results reveal how geometry rules the rigidity of shells. © 2012 American Physical Society.

  14. Double containment shell for nuclear power plants

    International Nuclear Information System (INIS)

    Sykora, D.

    1977-01-01

    A double containment shell is proposed for nuclear power plants, especially those equipped with pressurized water reactors. The shell offers increased environmental protection from primary circuit accidents. The inner shell is built of steel or concrete while the outer shell is always built of concrete. The space between the two shells is filled with water and is provided with several manholes and with stiffeners designed for compensation for load due to the water hydrostatic pressure. Water serves the airtight separation of the containment shell inside from the environment and the absorption of heat released in a primary circuit accident. In case the inner shell is made of concrete, it is provided with heat-removal tubes in-built in its walls ensuring rapid heat transfer from the inside of the containment to the water in the interwall space.

    2016-01-01

    This volume focuses on the relevant general theory and presents some first applications, namely those based on classical shell theory. After a brief introduction, during which the history and state-of-the-art are discussed, the first chapter presents the mechanics of anisotropic heterogeneous shells, covering all relevant assumptions and the basic relations of 3D elasticity, classical and refined shell models. The second chapter examines the numerical techniques that are used, namely discrete orthogonalization, spline-collocation and Fourier series, while the third highlights applications based on classical theory, in particular, the stress-strain state of shallow shells, non-circular shells, shells of revolution, and free vibrations of conical shells. The book concludes with a summary and an outlook bridging the gap to the second volume.

    Thai traditional medicine (TTM) is widely practiced in Thailand and continues to gain importance in cancer management, but little is known about the TTM practitioners' emic concepts and practice. With this study we firstly aim to document the practice of cancer treatment and prevention by TTM practitioners and, secondly, to evaluate how such traditional concepts and practices are correlated with biomedical ones. This in turn can form the basis for developing novel strategies for designing pharmacological experiments and longer term strategies to develop TTM practice. Semi-structured interviews with 33 TTM practitioners were performed in five provinces in different regions of Thailand. The following information were recorded; basic information of informants, descriptions of cancer (mareng in Thai), causes, diagnosis, treatment, and prevention. Plants used in the treatment and prevention of mareng were also collected. Using an in depth ethnographic approach four representative case studies to assist in a better understanding of the characteristics of mareng, its diagnosis, treatment, and prevention are reported here. Five characteristics of mareng - waste accumulation (khong sia), chronic illnesses (krasai), inflammation (kan aksep), bad blood (luead) and lymph (namlueang), and the imbalance of four basic elements (dhātu si) - have been identified. Explanatory models of cancer in TTM were linked with biomedical concepts and relevant pharmacological actions. Traditional uses and available scientific evidence of medicinal plants mentioned in the case studies for the treatment or prevention of mareng are presented and discussed. Here for the first time five main characteristics of cancer based on Thai traditional medical concepts are analysed. Our findings are relevant not only for the planning of clinical studies or pharmacological experiment in the search for novel compounds for cancer treatment and prevention, but also for the integration of Thai traditional

    The purpose of the study was to compare the effects of different frequencies of Muay Thai training on body composition, and physical fitness in healthy untrained women. Twenty women were randomly assigned to one of two training groups: G2X (n = 9) performed Muay Thai twice a week, while G3X (n = 11) performed the same program three times a week, both for 13 weeks. Anthropometric dimensions, fat-free mass, fat mass, resting metabolic rate, VO2 max, upper-body and abdominal muscle endurance, explosive leg power, agility, flexibility, and dietary intake were measured at pre and post-training. Training intensity was estimated every training session by rating of perceived exertion with a Borg 10- point scale. Both groups significantly improved in all measured physical fitness variables, without any significant changes in body composition. G2X was not significantly different from G3X on any variable. Average relative changes for all performance variables in G2X and G3X were 28.5% and 27.5%, respectively. Thirteen-weeks of Muay Thai practice can improve physical fitness in women, regardless of weekly frequency (two or three times a week). This suggests that instructors and coaches can structure a Muay Thai training program based on a twice or three-times per week protocol in order to promote positive changes in several important outcomes related to health for healthy untrained women. Moreover, practitioners are able to choose their training frequency preference, since both frequencies provided similar adaptations.

    This paper is a report of the psychometric properties of the Thai language versions of the Childbirth Self-Efficacy Inventory and the Childbirth Attitudes Questionnaire, and the equivalence of the Thai and English versions of these instruments. The Childbirth Self-Efficacy Inventory and the Childbirth Attitudes Questionnaire were developed to measure women's abilities to cope with labour and fear of childbirth. Consistent with Bandura's Self-Efficacy Theory, women who have greater confidence in their ability to cope with labour have reported having less fear in childbirth. However, research is needed to validate the measures and this relationship in countries other than the United States of America, where the tools were developed. Back-translation was used. Content validity was examined by experts. The psychometric properties were estimated with internal consistency reliability, construct validity, contrasted groups and criterion-related validity with 148 pregnant women at a hospital in Thailand in 2008. Both measures were shown to have high internal consistency. Contrasting group and criterion-related validity were consistent with self-efficacy theory and findings in the United States. Differences between the stages of labour across expectancies in the Childbirth Self-Efficacy inventory were found only for second stage. Support for good validity and reliability of the instruments when used with Thai women was demonstrated. It may be appropriate for Thai women to use The Childbirth Self-Efficacy Inventory only in relation to the second stage of labour. © 2010 The Authors.

    Gamma irradiation was applied to extend the shelf life of selected Thai prepared meals, which comprised rice, meats and vegetables and which were kept under chilled conditions. For Thai spicy chicken basil rice (kao ka pao kai), cooked rice was prepared so as to obtain a harder texture and irradiated at 2 kGy. Three components (cooked chicken, sauce and blanched basil leaf) were separately packed and irradiated at 2 kGy for chicken and sauce and 0.1 kGy for basil leaves. The shelf life of irradiated spicy chicken (2 kGy) separately packed (>4 weeks) was much longer than the control sample (2 weeks), considering sensory quality. However, this dose was not enough to kill entirely the inoculated Listeria monocytogenes in spicy cooked chicken. Likewise, there is a need to preserve basil leaf, since it was microbiologically spoiled by the second week of storage. For stir-fried rice noodle with dried shrimp (pad Thai), a dose of 4 kGy was recommended because the product was free from L. monocytogenes and Escherichia coli, safe from microbial spoilage and had acceptable sensory quality. Irradiation at 4 kGy could extend the shelf life of chilled pad Thai to more than 4 weeks compared with a normal chilled ready meal, which has a shelf life of 5-7 d. For steamed sticky rice, roasted chicken and papaya salad (kao neaw som tom), a dose of 3 kGy was enough to control L. monocytogenes and E. coli during chilled storage. The product irradiated at 3 kGy and upwards remained microbiologically safe after 8 weeks of chilled storage whereas the non-irradiated sample was spoiled after the second week. Panellists accepted irradiated steamed sticky rice and roasted chicken, which kept under chilled conditions for 8 weeks, but they rejected irradiated papaya salad owing to the soft texture and tainted taste.

    To investigate the relationship between Facebook addiction and mental health among high school students. This cross-sectional analytic study was performed among 972 high school students from four provinces associated with high economic prosperity in Thailand: Bangkok, ChiangMai, Ubon Ratchathani and Songkhla, utilizing a multistage cluster sampling technique. Facebook addiction was assessed using the Thai version of the Bergen-Facebook Addiction Scale (Thai-BFAS), while a Thai version ofthe General Health Questionnaire (Thai GHQ-28) was used for mental health evaluation. The relationship between Facebook addiction and mental health was analyzed through multiple logistic regressions. The prevalence of Facebook addiction and abnormal mental health were 41.9% (95% CI; 38.6, 45.2), and 21.9% (95% CI; 19.2, 24.8), respectively. After adjustment for confounding factors (sufficiency of household income, school location, level of education, GPAX learning deficits and attention deficit hyperactivity disorder), the individuals identified as having Facebook addiction were discovered to be at a high risk of developing abnormal general mental health (ORadj = 1.7, 95% CI: 1.1, 2.4), somatic symptoms (OR = 1.2, 95% CI: 0.9, 1.7), anxiety and insomnia (ORadj = 1.3, 95% CI: 0.9, 1.8), social dysfunction (OR = 1.5, 95% CI: 1.1, 2.1) and severe depression (ORadj = 1.5, 95% CI: 1.0, 2.2). Moreover; there were pronounced trends of increasing risk according to the level of Facebook addiction (Ptrend students could be associated with abnormal, general mental health status, somatic symptoms, anxiety & insomnia, social dysfunction, and severe depression. Therefore, it is essential that the relevant authorities educate young people about the mental health impacts linked with Facebook addictive usage and impose appropriate public health policies by screening Facebook addiction and mental health issues in risk groups.

This study aimed to (a study time spent on television in Thai infants and toddlers (age Methods Two hundred and sixty children and their parents were recruited into the study. Time spent on television and parental perceptions on television viewing toward their child's development were recorded during face-to-face and telephone interviews. Language development was assessed at the age of 2 years using the Clinical Linguistic Auditory Milestone Scale (CLAMS, and parents' report. Association between delayed language development and time spent on television viewing, as well as other various parameters such as gender, maternal education and family income, were analysed using a multivariate logistic regression model. Results Most Thai infants and toddlers watched television at the age of 6 months, 1 year and 2 years old (98.0, 95.3 and 96.7%, respectively. On average, 1-year-old children watched television 1.23 ± 1.42 hours per day. This increased to 1.69 ± 1.56 hours per day when they were 2 years old. However, watching television longer than 2 hours per day did not associate with delayed language development. On multivariate logistic regression analysis, gender (male was the only significant factor associated with delayed language development (OR = 6.9, 95% CI = 1.5–31.3. Moreover, 75%, 71%, and 66% of Thai parents believed that television viewing yielded benefits to children's developments. Conclusion Thai children commenced watching television at an early age and the amount of television viewing time increased by age. Most parents had positive perceptions to television viewing. The study found no association between time spent on television viewing (≥ 2 hours per day and delayed language development at the age of 2 years. Gender (male was the only variable associated with delayed language development.

    This study assessed the accuracy of age estimates produced by a regression equation derived from lower third molar development in a Thai population. The first part of this study relied on measurements taken from panoramic radiographs of 614 Thai patients aged from 9 to 20. The stage of lower left and right third molar development was observed in each radiograph and a modified Gat score was assigned. Linear regression on this data produced the following equation: Y=9.309+1.673 mG+0.303S (Y=age; mG=modified Gat score; S=sex). In the second part of this study, the predictive accuracy of this equation was evaluated using data from a second set of panoramic radiographs (539 Thai subjects, 9 to 24 years old). Each subject's age was estimated using the above equation and compared against age calculated from a provided date of birth. Estimated and known age data were analyzed using the Pearson correlation coefficient and descriptive statistics. Ages estimated from lower left and lower right third molar development stage were significantly correlated with the known ages (r=0.818, 0.808, respectively, P≤0.01). 50% of age estimates in the second part of the study fell within a range of error of ±1 year, while 75% fell within a range of error of ±2 years. The study found that the equation tends to estimate age accurately when individuals are 9 to 20 years of age. The equation can be used for age estimation for Thai populations when the individuals are 9 to 20 years of age

The stage of lower left and right third molar development was observed in each radiograph and a modified Gat score was assigned. Linear regression on this data produced the following equation: Y=9.309+1.673 mG+0.303S (Y=age; mG=modified Gat score; S=sex). In the second part of this study, the predictive accuracy of this equation was evaluated using data from a second set of panoramic radiographs (539 Thai subjects, 9 to 24 years old). Each subject's age was estimated using the above equation and compared against age calculated from a provided date of birth. Estimated and known age data were analyzed using the Pearson correlation coefficient and descriptive statistics. Ages estimated from lower left and lower right third molar development stage were significantly correlated with the known ages (r=0.818, 0.808, respectively, P≤0.01). 50% of age estimates in the second part of the study fell within a range of error of ±1 year, while 75% fell within a range of error of ±2 years. The study found that the equation tends to estimate age accurately when individuals are 9 to 20 years of age. The equation can be used for age estimation for Thai populations when the individuals are 9 to 20 years of age.

    The efficiency and productivity of aquaculture strongly depends on the development of advanced technology for water quality management system. The most important factor for the success of intensive aquaculture system is controlling the water quality of fish rearing media. This paper reports the design of fine bubbles (FBs) generator and performance evaluation of the system to improve water quality in thai catfish media (10 g/ind) with density (16.66 ind./L). The FBs generator was designed to control the size distribution of bubble by controlling its air flow rate entry to the mixing chamber of the generator. The performance of the system was evaluated based on the produced debit, dissolved oxygen rate and ammonia content in the catfish medium. The size distribution was observed by using a high speed camera image followed by processing using ImageJ. freeware application. The results show that air flow rate 0.05 L/min and 0.1 L/min received average bubble size of 29 µm and 31 µm respectively. The generator produced bubbles with capacity of 6 L/min and dissolved oxygen rate 0.2 ppm/min/L. The obtained DO growth was 0.455 ppm/second/L while the average decay rate was 0.20 ppm/second/L. (0.011/0.005 fold). In contrast, the recieved DO growth rate is faster compared to the DO consumption rate of the Thai catfish. This results indicated that the potential application of FBs enhanced the density of thai catfish seed rearing. In addition, ammonia can be reduced at 0.0358 ppm/hour/L and it is also observed that the inhibition of bacterial growth of air FBs is postive to Aeromonas hydrophila bacteria compared to the negative control. It is concluded that as-developed FBs system can be potentially applied for intensive thai catfish culture and expected to improve the feeding efficiency rate.

    Some mistakes in the evaluation of the proven reserves of Royal Dutch Shell group, the second world petroleum leader, will oblige the other oil and gas companies to be more transparent and vigilant in the future. The proven reserves ('P90' in petroleum professionals' language) are the most important indicators of the mining patrimony of companies. These strategic data are reported each year in the annual reports of the companies and are examined by the security exchange commission. The evaluation of reserves is perfectly codified by the US energy policy and conservation act and its accountable translation using the FAS 69 standard allows to establish long-term cash-flow forecasts. The revision announced by Shell on January 9 leads to a 20% reduction of its proven reserves. Short paper. (J.S.)

    Future Integrated Coal Gasification Combined Cycle (ICGCC) power plants will have superior environmental performance and efficiency. The Shell Coal Gasification Process (SCGP) is a clean coal technology, which can convert a wide range of coals into clean syngas for high efficiency electricity generation in an ICGCC plant. SCGP flexibility has been demonstrated for high-rank bituminous coals to low rank lignites and petroleum coke, and the process is well suited for combined cycle power generation, resulting in efficiencies of 42 to 46% (LHV), depending on choice of coal and gas turbine efficiency. In the Netherlands, a 250 MWe coal gasification combined cycle plant based on Shell technology has been built by Demkolec, a development partnership of the Dutch Electricity Generating Board (N.V. Sep). The construction of the unit was completed end 1993 and is now followed by start-up and a 3 year demonstration period, after that the plant will be part of the Dutch electricity generating system.

    1993-01-01

    This presentation emphasizes the importance of a detailed description of the nonlinear deviatoric (strength) response of the surrounding rock in the numerical simulation of underground nuclear explosion phenomenology to the late times needed for test ban monitoring applications. We will show how numerical simulations which match ground motion measurements in volcanic tuffs and in granite use the strength values obtained from laboratory measurements on small core samples of these rocks but also require much lower strength values after the ground motion has interacted with the rock. The underlying physical mechanisms for the implied strength reduction are not yet well understood, and in fact may depend on the particular rock type. However, constitutive models for shock damage and/or effective stress have been used successfully at S-Cubed in both the Geophysics Program (primarily for DARPA) and the Containment Support Program (for DNA) to simulate late time ground motions measured at NTS in many different rock types

    Full Text Available Rho kinases (ROCKs have a crucial role in actin-cytoskeletal reorganization and thus are involved in broad aspects of cell motility, from smooth muscle contraction to neurite outgrowth. The first marketed ROCK inhibitor, called fasudil, has been used safely for treatment of cerebral vasospasm since 1995 in Japan. During the succeeding decades ROCK inhibitors have been applied in many pathological conditions from central nervous system disorders to cardiovascular disease as potential therapeutic agents or experimental tools to help understand the underlying (pathomechanisms. In 2014, a fasudil derivate named ripasudil was accepted for clinical use in glaucoma and ocular hypertension. Since ROCK kinases are widely expressed in ocular tissues, they have been implicated in the pathology of many ocular conditions such as corneal dysfunction, glaucoma, cataract, diabetic retinopathy, age-related macular degeneration, and retinal detachment. This paper aims to provide an overview of the most recent status/application of ROCK inhibitors in the field of eye disease.

    Superfluid helium consists of two inter-penetrating fluids, a viscous normal fluid and an inviscid superfluid, coupled by a mutual friction. We develop a two-fluid shell model to study superfluid turbulence and investigate the energy spectra and the balance of fluxes between the two fluids in a steady state. At sufficiently low temperatures a 'bottle-neck' develops at high wavenumbers suggesting the need for a further dissipative effect, such as the Kelvin wave cascade.

    The layered → rock-salt phase transformation in the layered dioxide cathodes for Li-ion batteries is believed to result in a “core-shell” structure of the primary particles, in which the core region maintains as the layered phase while the surface region undergoes the phase transformation to the rock-salt phase. Using transmission electron microscopy, here we demonstrate the formation of an “anti-core-shell” structure in cycled primary particles with a formula of LiNi0.80Co0.15Al0.05O2, in which the surface and subsurface regions remain as the layered structure while the rock-salt phase forms as domains in the bulk with a thin layer of the spinel phase between the rock-salt core and the skin of the layered phase. Formation of this anti-core-shell structure is attributed to the oxygen loss at the surface that drives the migration of oxygen from the bulk to the surface, thereby resulting in localized areas of significantly reduced oxygen levels in the bulk of the particle, which subsequently undergoes the phase transformation to the rock-salt domains. The formation of the anti-core-shell rock-salt domains is responsible for the reduced capacity, discharge voltage and ionic conductivity in cycled cathode.

    There is a dynamic growth of market for chilled prepared meals in Thailand because of the growth of food services in supermarkets and convenient stores. However, the shelf life of this food is short furthermore it is implicated in a number of serious foodborne disease outbreaks. Irradiation could provide a potential to improve the microbiological safety and extend the shelf life of chilled prepared meals. It is possibly used alone or together with chilling. With the combination of irradiation and chilling, frozen condition could be replaced resulting to saving in energy and cost. However, there is a limitation of information about the application of irradiation on chilled prepared meals. Also, information relevant to the application of food safety control system like Hazard Analysis and Critical Control Point (HACCP) should be gathered to ensure more safety of the irradiated prepared meals. For Thai dishes, they are normally composed of herb and spicy with different types of meat. All dishes are eaten along with rice. Both Thai aromatic rice and herb are susceptible to deterioration in quality by processing factors. Therefore, the study of the effect of irradiation on Thai dishes, which compose of these two components, is necessary.

    Muay Thai fighters strongly rely on the use of the roundhouse kick due to its effectiveness (i.e. power) and implications on the final score. Therefore, different striking tempos at full power are used during training as a method to enhance kicking power. However, the neuromuscular responses are unknown. Thus, the goal of this study was to investigate neuromuscular responses to a single bout of shorter (every second = H1) and longer (every 3s = H3) kick striking time intervals, measured with the countermovement jump (CMJ). Nine professional Muay Thai fighters participated in this randomized, cross-over trial. CMJs were measured on force plates before and after (post 0min, post 5min, post 10min, post 20min and post 30min) two striking (1set x 20reps) conditions (H1; H3). Although no difference was observed between H1 and H3 values, neuromuscular fatigue parameters displayed different patterns over time. CMJ height decreased immediately after H3 striking (PMuay Thai and conditioning coaches should focus on hard striking with both long and slow pacing during specific heavy bag or pad work.

    This study was designed to determine situation and effectiveness of the safety management system currently implemented in the Royal Thai Air Force. Reviewing the ICAO's SMS and the RTAF's SMS was conducted to identify similarities and differences between the two safety management systems. Later, the researcher acquired safety statistics from the RTAF Safety Center to investigate effectiveness of its safety system. The researcher also collected data to identify other factors affecting effectiveness of the safety system during conducting in-depth interviews. Findings and Conclusions: The study shows that the Royal Thai Air Force has never applied the International Civil Aviation Organization's Safety management System to its safety system. However, the RTAF's SMS and the ICAO's SMS have been developed based on the same concepts. These concepts are from Richard H. Woods's book, Aviation safety programs: A management handbook. However, the effectiveness of the Royal Thai Air Force's safety system is in good stance. An accident rate has been decreasing regularly but there are no known factors to describe the increasing rate, according to the participants' opinion. The participants have informed that there are many issues to be resolved to improve the RTAF's safety system. Those issues are cooperation among safety center's staffs, attitude toward safety of the RTAF senior commanders, and safety standards.

    Within the context of Rosenbaum's theory of learned resourcefulness, this correlational study examined the relationships among family functioning, self-esteem, and resourceful coping in Thai adolescents with asthma. A convenience sample of 132 Thai adolescents (aged 12-17 years) with asthma was recruited from the outpatient asthma clinics of four hospitals in Bangkok. Self-administered questionnaires included an assessment of demographic information and asthma status, the revised Family APGAR, the Rosenberg Self-Esteem Scale, and the Children's Self-Control Scale. Hierarchical multiple regression analysis was used to examine the relationships among variables. Effective family functioning had a significant positive effect on self-esteem (beta = .27, p self-esteem was not significantly correlated with resourceful coping (beta = .15, p = .08). The findings suggest that nursing interventions should take into account the role of family functioning in promoting self-esteem and resourceful coping in Thai adolescents with asthma. Recommendations for future research include replication of the study with a larger sample of adolescents with asthma and with adolescents with other chronic illnesses.

    Although, the effect of Ramadan fasting on the risks for Cardiovascular Disease (CVD) has been reported in several studies, the results were inconsistent. In addition, the effect of Ramadan fasting on biochemical parameters in Thai subjects has not been evaluated. The aim of this study was to investigate the effect of Ramadan fasting on anthropometry, blood pressure, Fasting Blood Glucose (FBG), lipid profiles, and body composition in healthy Thai subjects. A total of 65 healthy subjects (21 men and 44 women) aged between 19-24 years were randomly recruited. Anthropometry, blood pressure, FBG, Total Cholesterol (TC), Triglyceride (TG), High Density Lipoprotein-Cholesterol (HDL-C), Low Density Lipoprotein-Cholesterol (LDL-C), and body composition were measured before Ramadan, end of Ramadan and after one month of Ramadan. There were no changes in anthropometry, blood pressure, lipid profiles and body composition in both genders before Ramadan, end of Ramadan and after one month of Ramadan. Nevertheless, FBG levels were significantly increased after one month of Ramadan compared with baseline (5.09±0.50 versus 4.83±0.38 mmol/L, p=0.016, respectively) in women. The Ramadan fasting did not affect the lipid, anthropometric and body composition in healthy Thai subjects. However, the increased FBG levels after one month of Ramadan were observed in women. To improve the favourable biochemical parameters after Ramadan fasting, the lifestyle modifications such as, increased intake of healthy diets and increased physical activity should be recommended.

    This study was undertaken to investigate the effects of green tea on weight reduction in obese Thais. A randomized, controlled trial involving 60 obese subjects (body mass index, BMI > 25 kg/m2) was conducted. All subjects consumed a Thai diet containing 3 meals (8373.6 kJ/day) for 12 weeks, prepared by the Nutritional Unit at Srinagarind Hospital. The diet contained 65% carbohydrates, 15% protein, and 20% fat. Body weight, BMI, body composition, resting energy expenditure, and substrate oxidation were measured at baseline, and during weeks 4, 8, and 12 of the study. Serum levels of leptin and urine VMA were measured at baseline and during the 12th week. Differences over time and between the treatments (green tea or placebo) over time were determined using two-factor ANOVA with repeated measures. In comparing the two groups, differences in weight loss were 2.70, 5.10, and 3.3 kg during the 4th, 8th, and 12th weeks of the study, respectively. At the 8th and 12th weeks of the study, body weight loss was significantly different (P tea can reduce body weight in obese Thai subjects by increasing energy expenditure and fat oxidation.

    This study sought to identify factors associated with intention to change sexual practices among heterosexual Thai males diagnosed with sexually transmitted infections (STIs). STI clinic patients (n = 247) reported their sexual behaviors and condom use during the previous 3 months. STI and HIV knowledge, motivation to change sexual practices, and behavioral skills were assessed. Then, self-reported behavior change intention, including consistent condom use, reducing number of sexual partners, not using drugs and alcohol when having sex, and refusal of condomless sex, was examined. Consistent condom use in the past 3 months by Thai males diagnosed with STIs was low across all types of sexual partners (lover 13.8%, casual partner 14.9%, and sex worker 2.5%). Risk reduction self-efficacy (p behavior change intention. Significant predictors of behavior change intention were risk reduction self-efficacy (p behavior change intention variance. Intervention aimed at enhancing motivation and behavioral skills to adopt preventive behaviors should be developed to prevent recurrent STIs, including HIV infection, among heterosexual Thai males diagnosed with STIs.

    2008-01-01

    The CDM Executive Board recently took a positive decision on programmatic CDM, also known as a CDM Programme of Activities. This prompts the author to present a new tool that has been developed recently for the Thai electricity market. The Renewable Energy Development (RED) Model, initially developed in the framework of the DANIDA funded project: Promotion of Renewable Energy in Thailand (PRET), at the Ministry of Energy of Thailand, was designed for the modelling of different incentive schemes and their effects on the Thai power system for the promotion of renewable energy technologies (RETs). Within this article, an extension of the existing RED model, including the CDM as additional incentive measure, is presented (RED-CDM). Along with the project-based approach, also a sectoral and programmatic approach is included as well. Several scenarios developed with the RED-CDM model show the influence of different incentive mechanisms on the Thai power market and their potentials for reaching the policy targets stated in the Energy Strategy of Thailand for Competitiveness. The main results show that reaching the policy targets is possible, while the price can be extremely high if the targets are to be achieved on schedule. Another important result is that a sectoral CDM approach could help financing about 20% of the incentives needed for a shift towards a more sustainable power grid, if the certified emission reductions (CERs) are sold at a price of 15 Euro/ton

    Studies of sexual behavior among HIV-infected Thai youth show conflicting results due to the different ages of the respondents. This study examined the relationships between sexual self-efficacy and risk behaviors among 92 HIV-positive Thai youth aged 14 to 21 years. A questionnaire previously validated in Thailand measured sexual self-efficacy. There were low levels of sexual activity with 13 respondents having sex in the last 6 months. The sexual self-efficacy scales were inversely related to the risk behaviors of having sex, having multiple partners, and drinking alcohol in the last 6 months. The scores of the sexual self-efficacy scale and its subscales were significantly lower in those aged 17 to 21 than in 14 to 16. Sexual risk behaviors were significantly higher in those aged 17 to 21 than in 14 to 16. These findings suggest that interventions to increase sexual self-efficacy should be emphasized as HIV-infected Thai youth reach late adolescence. © The Author(s) 2013.

    This paper is a report of a study of how Thai Buddhist people with type 2 diabetes practice self-management. The importance of diabetes self-management is recognized in the literature. However, research on self-care management in Thailand, in particular concerning Buddhist people with type 2 diabetes, is scarce. A descriptive qualitative study was conducted. Purposive convenience sampling was used, and thirty men and women with diabetes, aged 28-79 years, participated. Data were collected from June to August 2009 and analysed by use of manifest and latent content analysis. Five themes of self-management among Thai Buddhist people with type 2 diabetes were identified: cultural influence on disease control, Buddhism and Thai culture, struggle for disease control, family support and economy a high priority. Even though the Buddhist people with diabetes had certain self-management capabilities, many had poor control of their blood sugar levels and needed assistance. Reference to Buddhist moderation can be an effective means of helping the people with diabetes better manage their disease and change their lifestyles. In addition to cultural and religious traditions, family, economy and social environment should be taken into account both in the care and in interventions aimed at helping people with diabetes cope and empowering them to control their disease. © 2011 Blackwell Publishing Ltd.

    Examine intakes of energy and macronutrients, and identify their food sources, in Thai preschool children. Data from the Thai National Health Examination Survey (NHES) IV were used. Mothers/caregivers were interviewed regarding their children's 24-hour-dietary intake. Dietary data were analyzed for energy and macronutrients, and their food sources were investigated. Due to skewed data, Mann-Whitney U test was used to compare energy and macronutrient intake between sexes and age groups. Among 256 preschool children, more than 90% had protein intakes higher than the recommended level. Only 12.7 to 29.0% met the recommended intake for energy. Amounts of carbohydrate and fat consumed varied from below to above the Dietary Reference Intake (DRI) recommendation. Intakes of carbohydrate in boys and fat in girls were statistically different between age groups (p energy came from dairy products, grains and starchy products. The major carbohydrate contributors were grains and starchy products. Dairy products were the main source of protein. Important food sources of fat were dairy products for one- to three-year-old children and fat and oils for four- to five-year-old children. Thai preschool children have inappropriate intakes of energy and macronutrients. Dairy products and grains and/or starchy products were the main sources of energy, carbohydrate, and protein. Dietary fat sources varied by age group.

    Full Text Available This paper deals with the result of the recognition under the ILO Conventions 87 and 98 of the freedom of association and subsequent introduction of union representation in the Royal Thai civil service. As a consequence, the Royal Thai Government has changed the Constitution to allow for union representation in its civil service. A decree has been drafted and focus groups have been interviewed to establish the views of a cross-section of civil servants on their expectations and desires in being allowed to form and join a union. The paper discusses the approach taken to union representation in terms of collective bargaining versus joint consultation and centralization versus decentralization and the discourse that has surfaced as a result of the interviews between the policy makers and civil servants, particularly with regard to its context of a high power distance culture. The analysis provides the best practice and effective approach to the introduction of union representation within the Thai Civil Service.

    To develop a conceptual framework of adherence to treatment among Thai people living with tuberculosis, a grounded theory approach was used. A purposive sample of 20 Thai people living with tuberculosis, aged from 23 to 85 years, was interviewed. From the participants' perspective, a core category of social belonging was highlighted, with three categories of conditions connected: personal barriers, personal resilience, and social facilitation. Personal barriers encompassed fear of stigma, concealing the illness, and lack of knowledge and motivation to complete the treatment regime. Personal resilience encompassed positive thinking and self-awareness. Social facilitation encompassed the ease of access to health services, continuity in the health service's ability to choose a directly-observed therapy observer, and social support. This study contributes a deeper understanding of the perspective of Thai people living with tuberculosis with regards to adherence to tuberculosis treatment. It might improve how local healthcare workers provide tuberculosis care, and inspire them to tailor care to people living with tuberculosis in a local community to increase personal resilience and reduce stigma. © 2017 John Wiley & Sons Australia, Ltd.

    In this study, MELCOR simulation was carried out for THAI HM-2 experiment of OECD. As a results, stratification of hydrogen cloud was reasonably captured in MELCOR simulation. Furthermore, the pressure from simulation results in cases where mass transfer coefficient of MELCOR condensation model was modified was good agreement with the experimental results. Containment Filtered Ventilation System (CFVS) has been introduced as facility to prevent containment failure during severe accident. However, possibility of hydrogen risk has been issued due to inflow of hydrogen, condensation and removal of steam and complicated inner structure in CFVS. Preferentially benchmark work for THAI HM-2 experiment of OECD was decided to validate the methodology before detailed assessment of hydrogen risk in CFVS. The objectives of THAI HM-2 experiment were evaluation of hydrogen behavior, verification of numerical analysis tools and so on. In this paper, therefore, MELCOR simulation was carried out in comparison with the experiment results. Additionally, steam condensation effect was considered for detailed simulation. Hydrogen concentration from MELCOR results was underestimated in comparison to the experimental results.

    Boxing is often believed to be a frequent cause for parkinsonism caused by chronic repetitive head injury, with Muhammad Ali frequently cited as an example. The purpose of this study is to determine the prevalence of Parkinson's disease (PD) in retired Thai traditional boxers. Two standardized screening questionnaires were sent to all registered Thai traditional boxers. Subjects who screened positive for parkinsonism were invited for clinical examinations by two independent neurologists. Among 704 boxers (70%) who completed the questionnaires, 8 boxers (1.14%) had parkinsonism: 5 with PD, 1 with progressive supranuclear palsy and 2 with vascular parkinsonism. Boxers with PD were found to have an older mean age than those without PD (P = 0.003). The analysis of probable risk factors disclosed an association between the number of professional bouts (>100 times) and PD (P = 0.01). The crude prevalence of PD in Thai boxers was 0.71% (95% CI: 0.09-1.33), with a significant increase with age. The prevalence rate of PD in those aged 50 and above was 0.17% (95% CI: 0.15-0.20), age-adjusted to the USA 1970 census, which is comparable to that of the general populations. The analysis determined that the number of professional bouts is a risk factor among these boxers, supporting the notion that repetitive head trauma may pose an additional risk to certain individuals who are already susceptible to PD. © 2010 Movement Disorder Society.

  4. Plastic buckling of cylindrical shells

    Cylindrical shells exhibit buckling under axial loads at stresses much less than the respective theoretical critical stresses. This is due primarily to the presence of geometrical imperfections even though such imperfections could be very small (e.g., comparable to thickness). Under internal pressure, the shell regains some of its buckling strength. For a relatively large radius-to-thickness ratio and low internal pressure, the effect can be reasonably estimated by an elastic analysis. However, for low radius-to-thickness ratios and greater pressures, the elastic-plastic collapse controls the failure load. in order to quantify the elastic-plastic buckling capacity of cylindrical shells, an analysis program was carried out by use of the computer code BOSOR5 developed by Bushnell of Lockheed Missiles and Space Company. The analysis was performed for various radius-to-thickness ratios and imperfection amplitudes. The purpose of the analytical program was to compute the buckling strength of underground cylindrical tanks, that are used for storage of nuclear wastes, for realistic geometric imperfections and internal pressure loads. This paper presents the results of the elastic-plastic analyses and compares them with other available information for various pressure loads

  5. Buckling shells are also swimmers

    Quilliet, Catherine; Dyfcom Bubbleboost Team

    We present an experimental and numerical study on the displacement of shells undergoing deformations in a fluid. When submitted to cycles of pressure difference between outside and inside, a shell buckles and debuckles, showing a succession of shapes and a dynamics that are different during the two phases. Hence such objects are likely to swim, including at low Reynolds (microscopic scale). We studied the swimming of buckling/debuckling shells at macroscopic scale using different approaches (force quantization, shape recording, displacement along a frictionless rail, study of external flow using PIV), and showed that inertia plays a role in propulsion, even in situations where dimensionless numbers correspond also to microswimmers in water. Different fluid viscosities were explored, showing an optimum for the displacement. Interestingly, the most favorable cases lead to displacements in the same direction and sense during both motor stroke (buckling phase) and recovery stroke (de-buckling phase). This work opens the route for the synthesis with high throughput of abusively simple synthetic swimmers, possibly gathered into nanorobots, actuated by a scalar field such as the pressure in echographic devices.

    The rural areas of Northern Thailand are home to a large cultural diversity of ethnic minority groups. Previous studies have shown that young people in rural Thailand have low levels of knowledge on HIV/AIDS and high sexual risks. We compared sexual behaviors between the lowland Thai youth and the youth from ethnic minority groups. This is a cross-sectional quantitative study conducted among high-school Thai and ethnic students in Chiang Mai. From a total 1215 participants, 487 (40.1%) were lowland Thai and 728 (59.9%) were from ethnic minorities. Overall, 17.9% of respondents reported "ever had sex." Lowland Thai adolescents were more likely to have ever had sex compared with ethnic minority adolescents (AOR, 1.61; CI, 1.06-2.45; P< 0.01). A higher proportion of lowland Thai respondents reported having ≥ 2 lifetime sexual partners (51.9% vs. 33.3%, P = 0.003), or currently having a boy/girlfriend (59.9% vs. 45.3%, P< 0.001) compared to ethnic minority adolescents. Consistent condom use was low in both groups (22.6%). The common significant factors associated with "ever had sex" in both groups were "ever drunk alcohol in the past year" and "currently having a boy/girlfriend." Specifically, for lowland Thai youth, being around the age of 17 or 18 years and "ever used methamphetamine in the past year" were associated with increased odds of "ever had sex". For ethnic minority adolescents, being female and belonging to religions other than Buddhism were associated with decreased odds of "ever had sex". A substantially higher proportion of lowland Thai engage in risky sexual behaviors when compared to ethnic minorities. However, both groups remained vulnerable to HIV and other sexually transmitted infections. To minimize sexual risks, education program and school-based interventions are warranted to increase awareness of young people about risky behaviors and to promote essential life skills.

  8. Natural analogue and microstructural studies in relation to radionuclide retardation by rock matrix diffusion in granite

    The possibility that radionuclide retardation by rock matrix diffusion will be limited in granitic rocks by geological factors is studied, as well as the possibility that diffusion will be confined to a narrow zone from water-conducting fractures. Petrophysical measurements, uranium series and geochemical analyses in the rock adjacent to fractures, have been performed to establish the extent of fracture-related microstructural changes that might influence the potential for diffusion and whether or not there is any record of diffusion of uranium, its daughters, or other elements. The results obtained from El Berrocal (Spain), Stripa (Sweden) and White-shell (Canada) granites, suggest that: (a) there is a zone adjacent to the fractures (generally less than 100 mm) where microstructural changes and enhanced uranium mobility exist; (b) the evidence for diffusion having taken place in the rock is confined largely to this zone. So, it appears that diffusivity determinations on rock collected away from the influence of fractures will not give representative data for diffusion modelling, in addition to the effect of distressing after removing rocks from depth. It is suggested that diffusion will be of limited effectiveness as a retardation mechanism in many granitic rocks, particularly in water movement confined to narrow channels where access by nuclides to the fracture walls is restricted. 51 refs., 56 figs., 9 tabs., 9 appendices

  10. Rock salt constitutive modeling

    International Nuclear Information System (INIS)

    Nickell, R.E.

    1980-01-01

    The Serata model is the best operational model available today because it incorporates: (1) a yield function to demarcate between viscoelastic and viscoplastic behavior of rock salt; (2) a pressure and temperature dependence for yield stresses; and (3) a standard linear solid, which can be readily extended into the non-linear regime, to represent creep behavior. Its only deficiencies appear to be the lack of secondary creep behavior (a free dashpot) and some unsettling arbitrariness about the Poisson's ratio (ν → 0.5) argument for viscoplasticity. The Sandia/WIPP model will have good primary and secondary creep capability, but lacks the viscoplastic behavior. In some cases, estimated inelastic strains may be underpredicted. If a creep acceleration mechanism associated with brine inclusions is observed, this model may require extensive revision. Most of the other models available (SAI, RE-SPEC, etc.) are only useful for short-term calculations, because they employ temporal power law (t/sup n/) primary creep representations. These models are unsatisfactory because they cannot represent dual mechanisms with differing characteristic times. An approach based upon combined creep and plasticity is recommended in order to remove the remaining deficiency in the Serata model. DOE/Sandia/WIPP should be encouraged to move aggressively in this regard

    Teollisuuden Voima Oy (TVO) has carried out research into basic rock types in Finland. The research programme has been implemented in parallel with the preliminary site investigations for radioactive waste disposal in 1991-1993. The program contained two main objectives: firstly, to study the properties of the basic rock types and compare those with the other rock types under the investigation; secondly, to carry out an inventory of rock formations consisting of basic rock types and suitable in question for final disposal. A study of environmental factors important to know regarding the final disposal was made of formations identified. In total 159 formations exceeding the size of 4 km 2 were identified in the inventory. Of these formations 97 were intrusive igneous rock types and 62 originally extrusive volcanic rock types. Deposits consisting of ore minerals, industrial minerals or building stones related to these formations were studied. Environmental factors like natural resources, protected areas or potential for restrictions in land use were also studied

    Skin microbiome varies from person to person due to a combination of various factors, including age, biogeography, sex, cosmetics and genetics. Many skin disorders appear to be related to the resident microflora, yet databases of facial skin microbiome of many biogeographies, including Thai, are limited. Metagenomics derived B-RISA and 16S rRNA gene sequencing was utilized to identify the culture-independent bacterial diversity on Thai male faces (cheek and forehead areas). Skin samples were categorized (grouped) into (i) normal ( teenage.hea ) and (ii) acne-prone ( teenage.acn ) young adults, and normal (iii) middle-aged ( middle.hea ) and (iv) elderly ( elderly.hea ) adults. The 16S rRNA gene sequencing was successful as the sequencing depth had an estimated >98% genus coverage of the true community. The major diversity was found between the young and elderly adults in both cheek and forehead areas, followed by that between normal and acne young adults. Detection of representative characteristics indicated that bacteria from the order Rhizobiales, genera Sphingomonas and Pseudoalteromonas , distinguished the elderly.hea microbiota, along the clinical features of wrinkles and pores. Prediction of the metabolic potential revealed reduced metabolic pathways involved in replication and repair, nucleotide metabolism and genetic translation in the elderly.hea compared with that in the teenage.hea . For young adults, some unique compositions such as abundance of Propionibacterium acnes and Staphylococcus epidermidis , with a minor diversity between normal and acne skins, were detected. The metabolic potentials of the acne vs. normal young adults showed that teenage.acn was low in many cellular processes (e.g., cell motility and environmental adaptation), but high in carbohydrate metabolism, which could support acne growth. Moreover, comparison with the age-matched males from the US (Boulder, Colorado) to gain insight into the diversity across national biogeography

    Existing fractures crossing a deposition hole may be activated and sheared by an earthquake. The effect of such a rock shear has been investigated by finite element calculations. The buffer material in a deposition hole acts as a cushion between the canister and the rock, which reduces the effect of a rock shear substantially. Lower density of the buffer yields softer material and reduced effect on the canister. However, at the high density that is suggested for a repository the stiffness of the buffer is rather high. The stiffness is also a function of the rate of shear, which means that there may be a substantial damage on the canister at very high shear rates. However, the earthquake induced rock shear velocity is lower than 1 m/s which is not considered to be very high. The rock shear has been modelled with finite element calculations with the code Abaqus. A three dimensional finite element mesh of the buffer and the canister has been created and simulation of a rock shear has been performed. The rock shear has been assumed to take place either perpendicular to the canister at the quarter point or at an inclined angle of 22.5 deg in tension. Furthermore horizontal shear has been studied using a vertical shear plane either at the centre or at 1/4-point for the canister. The shear calculations have been driven to a total shear of 10 cm. The canister also has to be designed to withstand the loads caused by a thick ice sheet. Besides rock shear the model has been used to analyse the effect of such glacial load (either combined with rock shear or without rock shear). This report also summarizes the effect when considering creep in the copper shell

    2016-12-01

    Rock glaciers are common in many mountain ranges in which the ELA lies above the peaks. They represent some of the most identifiable components of today's cryosphere in these settings. Their oversteepened snouts pose often-overlooked hazards to travel in alpine terrain. Rock glaciers are supported by avalanches and by rockfall from steep headwalls. The winter's avalanche cone must be sufficiently thick not to melt entirely in the summer. The spatial distribution of rock glaciers reflects this dependence on avalanche sources; they are most common on lee sides of ridges where wind-blown snow augments the avalanche source. In the absence of rockfall, this would support a short, cirque glacier. Depending on the relationship between rockfall and avalanche patterns, "talus-derived" and "glacier-derived" rock glaciers are possible. Talus-derived: If the spatial distribution of rock delivery is similar to the avalanche pattern, the rock-ice mixture will travel an englacial path that is downward through the short accumulation zone before turning upward in the ablation zone. Advected debris is then delivered to the base of a growing surface debris layer that reduces the ice melt rate. The physics is identical to the debris-covered glacier case. Glacier-derived: If on the other hand rockfall from the headwall rolls beyond the avalanche cone, it is added directly to the ablation zone of the glacier. The avalanche accumulation zone then supports a pure ice core to the rock glacier. We have developed numerical models designed to capture the full range of glacier to debris-covered glacier to rock glacier behavior. The hundreds of meter lengths, tens of meters thicknesses, and meter per year speeds of rock glaciers are well described by the models. The model can capture both "talus-derived" and "glacier-derived" rock glaciers. We explore the dependence of glacier behavior on climate histories. As climate warms, a pure ice debris-covered glacier can transform to a much shorter rock

    The types of fault rocks, microstructural characteristics of fault tectonite and their relationship with uranium mineralization in the uranium-productive granite area are discussed. According to the synthetic analysis on nature of stress, extent of crack and microstructural characteristics of fault rocks, they can be classified into five groups and sixteen subgroups. The author especially emphasizes the control of cataclasite group and fault breccia group over uranium mineralization in the uranium-productive granite area. It is considered that more effective study should be made on the macrostructure and microstructure of fault rocks. It is of an important practical significance in uranium exploration

    Potash mining, salt mining, design of solution caverns in salt rocks, disposal of waste in salt repositories, and the use of granular halite backfill in underground salt rock mines are all mining activities which are practised or contemplated for the near future. Whatever the purpose, the need for high quality design parameters is evident. The authors have been testing salt rocks in the laboratory in a number of configurations for some time. Great care has been given to the quality of sample preparation and test methodology. This paper describes the methods, presents the elements of equipment design, and shows some typical results

    Highlights: • Large scale facility for investigating representative LWR severe accident scenarios. • Coupled effect tests in the field of thermal-hydraulics, hydrogen, aerosol and iodine. • Measurement techniques improved and adapted for severe accident conditions. • Testing of passive mitigation systems (e.g. PAR) under accident conditions. • THAI data application for validation and development of CFD and LP codes. - Abstract: The test facility THAI (thermal-hydraulics, hydrogen, aerosol, and iodine) aims at addressing open questions concerning gas distribution, behaviour of hydrogen, iodine and aerosols in the containment of light water reactors during severe accidents. Main component of the facility is a 60 m{sup 3} stainless steel vessel, 9.2 m high and 3.2 m in diameter, with exchangeable internals for multi-compartment investigations. The maximal design pressure of the vessel is 14 bar which allows H{sub 2} combustion experiments at a severe accident relevant H{sub 2} concentration level. The facility is approved for the use of low-level radiotracer I-123 which enables the measurement of time resolved iodine behaviour. The THAI test facility allows investigating various accident scenarios, ranging from turbulent free convection to stagnant stratified containment atmospheres and can be combined with simultaneous use of hydrogen, iodine and aerosol issues. THAI experimental research also covers investigations related to mitigation systems employed in light water reactor containments by performing experiments on, e.g. pressure suppression pool hydrodynamics, performance behaviour of passive autocatalytic recombiners, and spray interaction with hydrogen–steam–air flames in phenomenon orientated and coupled-effects experiments. The THAI experimental data have been widely used for the validation and further development of Lumped Parameter and Computational Fluid Dynamics codes with 3D capabilities, e.g. International Standard Problems ISP-47 (thermal
