    Full Text Available Abstract Background Symptom-based surveys suggest that the prevalence of gastrointestinal diseases is lower in China than in Western countries. The aim of this study was to validate a methodology for the epidemiological investigation of gastrointestinal symptoms and endoscopic findings in China. Methods A randomized, stratified, multi-stage sampling methodology was used to select 18 000 adults aged 18-80 years from Shanghai, Beijing, Xi'an, Wuhan and Guangzhou. Participants from Shanghai were invited to provide blood samples and undergo upper gastrointestinal endoscopy. All participants completed Chinese versions of the Reflux Disease Questionnaire (RDQ and the modified Rome II questionnaire; 20% were also invited to complete the 36-item Short Form Health Survey (SF-36 and Epworth Sleepiness Scale (ESS. The psychometric properties of the questionnaires were evaluated statistically. Results The study was completed by 16 091 individuals (response rate: 89.4%, with 3219 (89.4% of those invited completing the SF-36 and ESS. All 3153 participants in Shanghai provided blood samples and 1030 (32.7% underwent endoscopy. Cronbach's alpha coefficients were 0.89, 0.89, 0.80 and 0.91, respectively, for the RDQ, modified Rome II questionnaire, ESS and SF-36, supporting internal consistency. Factor analysis supported construct validity of all questionnaire dimensions except SF-36 psychosocial dimensions. Conclusion This population-based study has great potential to characterize the relationship between gastrointestinal symptoms and endoscopic findings in China.

    Full Text Available Objectives. We report the single-incision laparoscopic cholecystectomy (SILC learning experience of 2 hepatobiliary surgeons and the factors that could influence the learning curve of SILC. Methods. Patients who underwent SILC by Surgeons A and B were studied retrospectively. Operating time, conversion rate, reason for conversion, identity of first assistants, and their experience with previous laparoscopic cholecystectomy (LC were analysed. CUSUM analysis is used to identify learning curve. Results. Hundred and nineteen SILC cases were performed by Surgeons A and B, respectively. Eight cases required additional port. In CUSUM analysis, most conversion occurred during the first 19 cases. Operating time was significantly lower (62.5 versus 90.6 min, P = 0.04 after the learning curve has been overcome. Operating time decreases as the experience increases, especially Surgeon B. Most conversions are due to adhesion at Calot’s triangle. Acute cholecystitis, patients’ BMI, and previous surgery do not seem to influence conversion rate. Mean operating times of cases assisted by first assistant with and without LC experience were 48 and 74 minutes, respectively (P = 0.004. Conclusion. Nineteen cases are needed to overcome the learning curve of SILC. Team work, assistant with CLC experience, and appropriate equipment and technique are the important factors in performing SILC.

    We present Spin-SILC, a new foreground component separation method that accurately extracts the cosmic microwave background (CMB) polarisation E and B modes from raw multifrequency Stokes Q and U measurements of the microwave sky. Spin-SILC is an internal linear combination method that uses spin wavelets to analyse the spin-2 polarisation signal P = Q + iU. The wavelets are additionally directional (non-axisymmetric). This allows different morphologies of signals to be separated and therefore the cleaning algorithm is localised using an additional domain of information. The advantage of spin wavelets over standard scalar wavelets is to simultaneously and self-consistently probe scales and directions in the polarisation signal P = Q + iU and in the underlying E and B modes, therefore providing the ability to perform component separation and E-B decomposition concurrently for the first time. We test Spin-SILC on full-mission Planck simulations and data and show the capacity to correctly recover the underlying cosmological E and B modes. We also demonstrate a strong consistency of our CMB maps with those derived from existing component separation methods. Spin-SILC can be combined with the pseudo- and pure E-B spin wavelet estimators presented in a companion paper to reliably extract the cosmological signal in the presence of complicated sky cuts and noise. Therefore, it will provide a computationally-efficient method to accurately extract the CMB E and B modes for future polarisation experiments.

    2015-04-01

    Full Text Available Validation is an essential and important step before the application of remote sensing products. This paper introduces a prototype of the validation network for remote sensing products in China (VRPC. The VRPC aims to improve remote sensing products at a regional scale in China. These improvements will enhance the applicability of the key remote sensing products in understanding and interpretation of typical land surface processes in China. The framework of the VRPC is introduced first, including its four basic components. Then, the basic selection principles of the observation sites are described, and the principles for the validation of the remote sensing products are established. The VRPC will be realized in stages. In the first stage, four stations that have improved remote sensing observation facilities have been incorporated according to the selection principles. Certain core observation sites have been constructed at these stations. Next the Heihe Station is introduced in detail as an example. The three levels of observation (the research base, pixel-scale validation sites, and regional coverage adopted by the Heihe Station are carefully explained. The pixel-scale validation sites with nested multi-scale observation systems in this station are the most unique feature, and these sites aim to solve some key scientific problems associated with remote sensing product validation (e.g., the scale effect and scale transformation. Multi-year of in situ measurements will ensure the high accuracy and inter-annual validity of the land products, which will provide dynamic regional monitoring and simulation capabilities in China. The observation sites of the VRPC are open, with the goal of increasing cooperation and exchange with global programs.

  8. Cost-Effectiveness of Introducing the SILCS Diaphragm in South Africa.

    Aurélia Lépine

    Full Text Available Though South Africa has high contraceptive use, unintended pregnancies are still widespread. The SILCS diaphragm could reduce the number of women with unmet need by introducing a discreet, woman-initiated, non-hormonal barrier method to the contraceptive method mix.A decision model was built to estimate the impact and cost-effectiveness of the introduction of the SILCS diaphragm in Gauteng among women with unmet need for contraception in terms of unintended and mistimed pregnancies averted, assuming that the available contraceptives on the market were not a satisfying option for those women. Full costs were estimated both from a provider's and user's perspective, which also accounts for women's travel and opportunity cost of time, assuming a 5% uptake among women with unmet contraceptive need. The incremental cost-effectiveness ratio is computed at five and 10 years after introduction to allow for a distribution of fixed costs over time. A probabilistic sensitivity analysis was conducted to incorporate decision uncertainty.The introduction of the SILCS diaphragm in Gauteng could prevent an estimated 8,365 unintended pregnancies and 2,117 abortions over five years, at an annual estimated cost of US$55 per woman. This comes to a cost per pregnancy averted of US$153 and US$171 from a user's and provider's perspectives, respectively, with slightly lower unit costs at 10 years. Major cost drivers will be the price of the SILCS diaphragm and the contraceptive gel, given their large contribution to total costs (around 60%.The introduction of the SILCS diaphragm in the public sector is likely to provide protection for some women for whom current contraceptive technologies are not an option. However to realize its potential, targeting will be needed to reach women with unmet need and those with likely high adherence. Further analyses are needed among potential users to optimize the introduction strategy.

    The Chinese Sun Hazemeter Network(CSHNET)provides the necessary ground-based observation to validate and assess the applicability of MODIS aerosol optical depth(AOD)products over different ecological and geographic regions in China for the first time.The validation results show that the comprehensive utilization ratio and applicability of MODIS products varied very much over different regions and seasons from August 2004 to July 2005.On the Tibetan Plateau,the comprehensive utilization ratio of MODIS data was low:MODIS products only accounted for 16% of the ground-based observation;on average,31% to 45% of MODIS products fell within the retrieval errors issued by NASA.A similar result was found in northern desert areas with the ratio of MODIS to observation ranging from 15% to 55%,with 7% to 39% of MODIS products within errors.In the remote northeast corner of China,low ratios of MODIS to observation were also found ranging from 14% to 46%,with 49% to 69% of MODIS within errors.The forested sites exhibited moderate ratios of MODIS to observation ranging from 46% to 65%,with 30% to 59% of MODIS within errors.This was similar to numbers observed at sites along eastern seashore of China and inland urban sites with the ratio of MODIS to observation between 63% to 75%,with 25% to 67% of MODIS within errors for sites along eastern seashore of China and 43% to 78%,with 35% to 75% of MODIS within errors for inland urban sites.The ratio of MODIS to observation over agricultural areas ranged from 61% to 89%;59%-88% of MODIS fell within the retrieval errors.At homogeneous and well vegetated areas,the comprehensive utilization ratio of MODIS products was over 80% and above 70% of MODIS products fell within the retrieval errors in growing Season.

    Rogers, Keir K; Leistedt, Boris; McEwen, Jason D; Pontzen, Andrew

    2016-01-01

    We present new clean maps of the CMB temperature anisotropies (as measured by Planck) constructed with a novel internal linear combination (ILC) algorithm using directional, scale-discretised wavelets --- Scale-discretised, directional wavelet ILC or SILC. Directional wavelets, when convolved with signals on the sphere, can separate the anisotropic filamentary structures which are characteristic of both the CMB and foregrounds. Extending previous component separation methods, which use the frequency, spatial and harmonic signatures of foregrounds to separate them from the cosmological background signal, SILC can additionally use morphological information in the foregrounds and CMB to better localise the cleaning algorithm. We test the method on Planck data and simulations, demonstrating consistency with existing component separation algorithms, and discuss how to optimise the use of morphological information by varying the number of directional wavelets as a function of spatial scale. We find that combining t...

    We present new clean maps of the cosmic microwave background (CMB) temperature anisotropies (as measured by Planck) constructed with a novel internal linear combination (ILC) algorithm using directional, scale-discretized wavelets - scale-discretized, directional wavelet ILC or Scale-discretised, directional wavelet Internal Linear Combination (SILC). Directional wavelets, when convolved with signals on the sphere, can separate the anisotropic filamentary structures which are characteristic of both the CMB and foregrounds. Extending previous component separation methods, which use the frequency, spatial and harmonic signatures of foregrounds to separate them from the cosmological background signal, SILC can additionally use morphological information in the foregrounds and CMB to better localize the cleaning algorithm. We test the method on Planck data and simulations, demonstrating consistency with existing component separation algorithms, and discuss how to optimize the use of morphological information by varying the number of directional wavelets as a function of spatial scale. We find that combining the use of directional and axisymmetric wavelets depending on scale could yield higher quality CMB temperature maps. Our results set the stage for the application of SILC to polarization anisotropies through an extension to spin wavelets.

    The quality of a newly merged soil moisture product (ECV_SM v0.1) from active and passive microwave sensors has attracted widespread international attention. The performance evaluation of this product will benefit studies on climate, meteorology, agriculture, hydrology, ecology and the environment. In this study, meteorological station data and the Noah soil moisture product were used to validate the ECV_SM product in China. First, some conventional statistical measures, such as correlation coefficients, bias, root mean square difference (RMSD) and mean relative error (MRE), were computed to describe the level of agreement between the meteorological station data and ECV_SM values. The accuracy was moderately high (the correlation was significant at the 0.05 level), although the two datasets differed slightly for various types of land cover. Compared with cropland and urban and built-up areas, the performance of ECV_SM was best in grassland regions. Second, the triple collocation technique was used to assess the random error in the meteorological station data, Noah soil moisture product and ECV_SM product. The mean errors in these three datasets were 0.108, 0.079 and 0.075 m3 m-3, respectively, on July 8, 2010 and 0.099, 0.061 and 0.059 m3 m-3, respectively, on October 8, 2010. Only two days of data were used for the triple collocation test as a representative, but this cannot precisely indicate that the test results on any other day correspond with the test results on these two days. Additionally, a trend analysis of ECV_SM during 2003-2010 was carried out using the Mann-Kendall trend test.

    Freshwater ecoregion is currently widely used by biologists, conservators and resource managers. Most of ecoregion delineations are developed at the basin scale and are not fully adapted in a practical manner because operational water resources management is primarily conducted by political administrative departments. In this study, an ecoregion delineation framework was proposed to classify three-level ecoregions in Jinan City with geographic information systems and cluster analysis. The first level ecoregion was composed of three watersheds (a part of the Yellow River, Xiaoqing River and Tuhaimajia River) plus the urban area, which was primarily determined on the basis of the city administrative divisions and river watersheds. The classification of the second level ecoregion is primarily based on the spatial heterogeneity of land use. The third level ecoregion was delineated for each second level ecoregion by using the cluster analysis on water quality. At the same time, administrative boundaries were used to rectify the boundaries of each ecoregion in this study to facilitate the administration of each ecoregion. Furthermore, ecological health assessment (IBI) based on fish communities were employed to validate the freshwater ecoregion. The results demonstrated that 73.3% of ecoregions were in line with the distribution of fish IBI, indicating that the freshwater ecoregions are acceptable for future water resources management.

    Full Text Available Abstract Background Gastroesophageal reflux disease (GERD causes a wide range of clinical symptoms and potentially serious complications, but epidemiological data about GERD in China are limited. The aim of this pilot study was to develop and validate a methodology for the epidemiological study of GERD in China. Methods Regionally stratified, randomized samples of Shanghai residents (n = 919 completed Mandarin translations of the Reflux Disease Questionnaire (RDQ, GERD Impact Scale, Quality of Life in Reflux and Dyspepsia (QOLRAD questionnaire and 36-item Short Form Health Survey (SF-36. Reliability and construct validity were tested by appropriate statistical analyses. Results The response rate was 86%. The test-retest reliability coefficients for the RDQ, GERD Impact Scale, QOLRAD and SF-36 were 0.80, 0.71, 0.93 and 0.96, respectively, and Cronbach's alpha coefficients were 0.86, 0.80, 0.98 and 0.90, respectively. Dimension scores were highly correlated with the total scores for the QOLRAD and SF-36, and factor analysis showed credible construct validity for the RDQ, GERD Impact Scale and SF-36. The RDQ GERD score was significantly negatively correlated with QOLRAD dimensions of food and drink problems and social functioning, and was significantly negatively correlated with all dimensions of the SF-36. All eight of the SF-36 dimensions were significantly correlated with the QOLRAD total score. Conclusion This study developed and tested a successful survey methodology for the investigation of GERD in China. The questionnaires used demonstrated credible reliability and construct validity, supporting their use in larger epidemiological surveys of GERD in China.

    Research on students' views on nature of science (VNOS) in Asian countries such as China is notably lacking. This study aimed to develop and validate an instrument to measure South China high school students' VNOS. Based on the previously acquired qualitative data, the instrument included seven VNOS dimensions which reflect the crucial aspects of NOS indicated by the literature and/or the dominating ideology in China (i.e., Marxism). A sample (N = 604) was randomly divided into two groups used for exploratory analyses and confirmatory analyses. The results indicated that the instrument expressed satisfactory reliability and validity and the seven NOS dimensions could be explained by a higher-order dimension. That is, the data of this study supported the multi-dimensional framework that treats VNOS as comprising several more-or-less correlated dimensions. Two distinct dimensions, namely "Accumulative-Empirical Source" and "Pragmatic Justification" which have not been explicitly specified in the past literature, were found. In addition, the Chinese high school students generally held a constructivist/relativist-oriented view of all seven dimensions. Differences in gender and grade level were hardly observed in any dimension of the instrument. The findings are further discussed through a socio-cultural lens to enrich the current understanding of VNOS.

  7. Validation and Algorithms Comparative Study for Microwave Remote Sensing of Snow Depth over China

    International Nuclear Information System (INIS)

    In this study, five different snow algorithms (Chang algorithm, GSFC 96 algorithm, AMSR-E SWE algorithm, Improved Tibetan Plateau algorithm and Savoie algorithm) were selected to validate the accuracy of snow algorithms over China. These algorithms were compared for the accuracy of snow depth algorithms with AMSR-E brightness temperature data and ground measurements on February 10-12, 2010. Results showed that the GSFC 96 algorithm was more suitable in Xinjiang with the RMSE range from 6.85cm to 7.48 cm; in Inner Mongolia and Northeast China. Improved Tibetan Plateau algorithm is superior to the other four algorithms with the RMSE of 5.46cm∼6.11cm and 6.21cm∼7.83cm respectively; due to the lack of ground measurements, we couldn't get valid statistical results over the Tibetan Plateau. However, the mean relative error (MRE) of the selected algorithms was ranging from 37.95% to 189.13% in four study areas, which showed that the accuracy of the five snow depth algorithms is limited over China

    In this paper, the performance of two operational ocean forecasting systems, the global Mercator Océan (MO) Operational System, developed and maintained by Mercator Océan in France, and the regional South China Sea Operational Forecasting System (SCSOFS), by the National Marine Environmental Forecasting Center (NMEFC) in China, have been examined. Both systems can provide science-based nowcast/forecast products of temperature, salinity, water level, and ocean circulations. Comparison and validation of the ocean circulations, the structures of temperature and salinity, and some mesoscale activities, such as ocean fronts, typhoons, and mesoscale eddies, are conducted based on observed satellite and in situ data obtained in 2012 in the South China Sea. The results showed that MO performs better in simulating the ocean circulations and sea surface temperature (SST), and SCSOFS performs better in simulating the structures of temperature and salinity. For the mesoscale activities, the performance of SCSOFS is better than MO in simulating SST fronts and SST decrease during Typhoon Tembin compared with the previous studies and satellite data; but model results from both of SCSOFS and MO show some differences from satellite observations. In conclusion, some recommendations have been proposed for both forecast systems to improve their forecasting performance in the near future based on our comparison and validation.

    The gap between the demand and delivery of mental health services in mainland China can be reduced by validating freely available and psychometrically sound psychological instruments. The present research examined the Chinese version of the 21-item Depression Anxiety Stress Scales (DASS-21). Study 1 administered the DASS-21 to 1,815 Chinese college students and found internal consistency indices (Cronbach's alpha) of .83, .80, and .82 for the Depression, Anxiety, and Stress subscales, respectively, and .92 for the total DASS total. Test-retest reliability over a 6-month interval was .39 to .46 for each of the 3 subscales and .46 for the total DASS. Moderate convergent validity of the Depression and Anxiety subscales was demonstrated via significant correlations with the Chinese Beck Depression Inventory (r = .51 at Time 1 and r = .64 at Time 2) and the Chinese State-Trait Anxiety Inventory (r = .41), respectively. Confirmatory factor analyses supported the original 3-factor model with 1 minor change (nonnormed fit index [NNFI] = .964, comparative fit index [CFI] = .968, and root mean square error of approximation [RMSEA] = .079). Study 2 examined the clinical utility of the Chinese DASS-21 in 166 patients with schizophrenia and 90 matched healthy controls. Patients had higher Depression and Anxiety but not Stress subscale scores than healthy controls. A discriminant function composed of the linear combination of 3 subscale scores correctly discriminated 69.92% of participants, which again supported the potential clinical utility of the DASS in mainland China. Taken together, findings in these studies support the cross-cultural validity of the DASS-21 in China. (PsycINFO Database Record PMID:26619091

  10. Ocean color products retrieval and validation around China coast with MODIS

    Waters along China coast are very turbid with high concentrations of suspended sediment nearly all the time, especially at the Hangzhou Bay, the Changjiang (Yangtze) River Estuary and the shoal along Jiangsu Province. In these turbid and optically complex waters, the standard MODIS ocean color products tend to have invalid values. Because the water-leaving radiances in the near-infrared (NIR) are significant resulting from the strong scattering of suspended particles, the standardMODIS atmospheric correction algorithm often gets no results or produces significant errors. And because of the complex water optical properties, the OC3 model used in the standard MODIS data processing tends to get extremely high chlorophyll-a (Chl-a) concentrations. In this paper, we present an atmospheric correction approach using MODIS short wave infrared (SWIR) bands based on the fact that water-leaving radiances are negligible in the SWlR region because of the extreme strong absorption of water even in turbid waters. A regional Chl-a concentration estimation model is also constructed for MODIS from in situ data. These algorithms are applied to MODIS Aqua data processing in the China coastal regions. In situ data collected in the Yellow Sea and the East China Sea in spring and autumn, 2003 are used to validate the performance. Reasonably good results have been obtained. It is noted that water-leaving reflectance in the NIR bands are significant in waters along the China coast with high sediment loadings. The satellite derived and in-situ reflectance spectra can match in the turbid waters along China coast, and there is relatively good linear relationship between satellite derived and in-situ reflectance. The RMSE value of Rrs(λ)is 0.0031 sr-1 for all the nine ocean color bands (412 to 869 nm). The satellite-derived Chl-a value is in the reasonable range and the root mean square percentage difference is 46.1%.

  12. Validating a dust production model by field experiment in Mu Us Desert, China

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    Field experiments of dust production have been seldom performed in Chinese deserts that are identified as one of main dust sources in the world, and such an experiment to validate a dust production model (DPM) has not been made in China until now. Saltation flux, dust emission flux, surface features and meteorological parameters (U*, Z0, Ri, etc.) were investigated in Mu Us Desert of China to verify the DPM model and accumulate dust emission data during the spring of 2002. It indicates that observed saltation fluxes from 0.07 to 8.00 g·m-1·s-1 are in good agreement with the ones predicted by the DPM model when the constant of the saltation flux equation is tuned to about 2.61, which corresponds to wind friction velocities from 0.26 to 0.35 m·s-1. Unfortunately, during three local dust emission events, the observed dust fluxes are from 1 to 3μg· m-2· s-1, lower than the modeled ones, implying that the model needs to be improved further under lower wind velocity. In comparison with data from a sandy soil with physical crust and a loam soil, saltation fluxes of the loose sandy soil in Mu Us Desert are obviously higher, which suggests that deserts and sandy land with desertification are major dust sources in northern China.

    Full Text Available This paper presents a rigorous validation of five widely used global land cover products, i.e., GLCC (Global Land Cover Characterization, UMd (University of Maryland land cover product, GLC2000 (Global Land Cover 2000 project data, MODIS LC (Moderate Resolution Imaging Spectro-radiometer Land Cover product and GlobCover (GLOBCOVER land cover product, and a national land cover map GLCD-2005 (Geodata Land Cover Dataset for year 2005 against an independent reference data set over China. The land cover reference data sets in three epochs (1990, 2000, and 2005 were collected on a web-based prototype system using a sampling-based labeling approach. Results show that, in China, the highest overall accuracy is observed in GLCD-2005 (72.3%, followed by MODIS LC (68.9%, GLC2000 (65.2%, GlobCover (57.7% and GLCC (57.2%, while UMd has the lowest accuracy (48.6%; all of the products performed best in representing “Trees” and “Others”, well with “Grassland” and “Cropland”, but problematic with “Water” and “Urban” across China in general. Moreover, in respect of GLCD-2005, there are significant accuracy differences across seven geographical locations of China, ranging from 46.3% in the Southwest, 77.5% in the South, 79.2% in the Northwest, 80.8% in the North, 81.8% in the Northeast, 82.6% in the Central, to 89.0% in the East. This study indicates that a regionally focused land cover map would in fact be more accurate than extracting the same region from a globally produced map.

    Full Text Available Background: Previous research has shown considerable variation in the relationship between women's educational attainment and second births in contemporary Europe. A negative association is found in some countries, while a positive or non-negative relationship is reported in others. Existing studies come mainly from single-country perspectives, which renders the results not strictly comparable. Objective: We investigate the association between women's and their partners' educational attainment and transition to second births comparatively in regions and sub-regions of Europe. Methods: The data come from the 2005 and 2011 waves of the EU Statistics on Income and Living Conditions (EU-SILC. We estimate separate discrete-time event history models for regions and sub-regions and multilevel models for all EU-SILC countries. Results: Northern Europe exhibits a positive association between women's and their partners' education and second childbearing. Western Europe features a positive relationship among partners but demonstrates a U-shaped pattern among women. This pattern occurs due to German-speaking countries where women's educational attainment appears inversely related to second births. A negative relationship between women's education and second childbearing also prevails in Eastern Europe; in some sub-regions it extends to male partners. Except for in Eastern Europe, the time-squeeze adds to the positive effect of women's high education. In Northern Europe it enables highly educated women to wholly catch up with their counterparts with medium and low education as regards the proportion having second births. In Southern Europe, by contrast, the educational gradient turns negative following the consideration of the time-squeeze effect. Conclusions: We conclude that the relationship between educational attainment and second births varies not only by individual country but also by larger geographical area in Europe. Although smaller in scale than

    Full Text Available OBJECTIVE: The aim of the paper is to report the development and psychometric testing of Diabetes Attitude Scale. METHOD: A prospective study was performed. The cultural equivalency and content validity of the Diabetes Attitude Scale were determined by panels of endocrinologists, physiologists, nurses and dieticians. An accurate and usable translation was obtained for each of five subscales examining attitudes on need for special training, the seriousness of type-2 diabetes, the need for controlling the condition, its psychosocial impact and the degree of autonomy given to patients in decision making. The validation was derived from 5961 patients with type-2 diabetes, recruited from 50 centers in 29 provinces throughout China between March 1st and September 30th, 2010. RESULTS: The modified Diabetes Attitude Scale showed an acceptable level of internal consistency. The strength of the inter-correlations among the domains of five subscales suggests that the instrument measures related but separate domains of patients' attitudes toward diabetes. Moreover, the test-retest intraclass correlation coefficients were high enough to support the stability of the Chinese version of the third version of the scale. CONCLUSIONS: The psychometric properties of the Chinese version of Diabetes Attitude Scale demonstrated satisfactory validity and reliability and appeared to effectively evaluate attitudes toward diabetes in patients with type-2 diabetes.

    STRs, scattered throughout the genome with higher mutation rate, are attractive to genetic application like forensic, anthropological and population genetics studies. STR profiling has now been applied in various aspects of human identification in forensic investigations. This work described the developmental validation of a novel and universal assay, the Huaxia Platinum System, which amplifies all markers in the expanded CODIS core loci and the Chinese National Database in one single PCR system. Developmental validation demonstrated that this novel assay is accurate, sensitive, reproducible and robust. No discordant calls were observed between the Huaxia Platinum System and other STR systems. Full genotypes could be achieved even with 250 pg of human DNA. Additionally, 402 unrelated individuals from 3 main ethnic groups of China (Han, Uygur and Tibetan) were genotyped to investigate the effectiveness of this novel assay. The CMP were 2.3094 × 10(-27), 4.3791 × 10(-28) and 6.9118 × 10(-27), respectively, and the CPE were 0.99999999939059, 0.99999999989653 and 0.99999999976386, respectively. Aforementioned results suggested that the Huaxia Platinum System is polymorphic and informative, which provides efficient tool for national DNA database and facilitate international data sharing.

  5. Validation and Variation of Upper Layer Thickness in South China Sea from Satellite Altimeter Data

    2008-06-01

    Full Text Available Satellite altimeter data from 1993 to 2005 has been used to analyze the seasonal variation and the interannual variability of upper layer thickness (ULT in the South China Sea (SCS. Base on in-situ measurements, the ULT is defined as the thickness from the sea surface to the depth of 16°C isotherm which is used to validate the result derived from satellite altimeter data. In comparison with altimeter and in-situ derived ULTs yields a correlation coefficient of 0.92 with a slope of 0.95 and an intercept of 6 m. The basin averaged ULT derived from altimeter is 160 m in winter and 171 m in summer which is similar to the in-situ measurements of 159 m in winter and 175 m in summer. Both results also show similar spatial patterns. It suggests that the sea surface height data derived from satellite sensors are usable for study the variation of ULT in the semi-closed SCS. Furthermore, we also use satellite derived ULT to detect the development of eddy. Interannual variability of two meso-scale cyclonic eddies and one anticyclonic eddy are strongly influenced by El Niño events. In most cases, there are highly positive correlations between ULT and sea surface temperature except the periods of El Niño. During the onset of El Niño event, ULT is deeper when sea surface temperature is lower.

    Global time series of the Essential Climate Variable (ECV) soil mositure (SM) is being developed from passive and active satellite microwave sensors at a coarse spatial resolution with Climate Change Initiative program funded by European Space Agency. This study aims to validate the reliability of ECV SM dataset, and attempts are made to analyze SM trends in cropland. Firstly, in-situ SM measurements during crop growing seasons from 1992 to 2010 for 228 stations across China and 21 stations over cropland of North China Plain (NCP) were employed to validate ECV SM product. Then, the spatiotemporal variations of ECV SM were analyzed during growing period of winter wheat (April-June) and summer maize (July-September) from 1981 to 2010 in NCP. Finally, the possible relationship between SM, precipitation, evapotranspiration and NDVI were explored. Results showed that ECV SM could generally capture the seasonal SM dynamics. The average triple collocation random error of ECV SM in China was 0.052 m3 m-3 while the error in cropland ranged from 0.003 to 0.156 m3 m-3. The averaged Spearman correlation coefficient between ECV SM and all in-situ observations was 0.42 (p < 0.01) in China and 0.43 (p < 0.01) for cropland over NCP. Spatially, ECV SM was decreasing in most areas during wheat season, whereas the trends of ECV SM were positive in south and negative in north during maize season in NCP, being consistent with the precipitation fluctuation. Overall, ECV SM is potentially suitable for trend analysis in NCP and its validations and analysis will be helpful for further enhancement of the ECV SM product.

    To evaluate the reliability and validity of the Chinese version of addiction severity index (ASl)-5th version (ASI-C-5), in illegal drug users receiving methadone maintenance treatment (MMT) in China. Methods One hundred and eighty-six heroin addicts (144 men and 42 women) receiving MMT at three clinics in Guizhou province, southwest China, were recruited. They were all interviewed with a questionnaire of ASI-C-5 and 35 were re-interviewed at an interval of seven days to assess its test-retest reliability. Results Cronbach's alpha for internal consistency of CSs varied from 0.60 to 0.81 in all domains. Test-retest reliability of composite scores (CSs) of ASI-C-5 were satisfactory (r=0.38-0.97). Based on item analysis and expert's suggestions, five items were deleted and one item was modified in ASI-C-5. Criterion validity of ASI-C-5 was found acceptable, as compared to addicts' self-rating anxiety scale (SAS) and self-rating depression scale (SDS) (r=0.59 and 0.45) except for social support rating scale (SSRS). Conclusions ASI-C-5 can be used for heroin addicts receiving MMT with acceptable reliability and validity.

  15. Vaporization of mercury from molten lead droplets doped with mercury: Pb/Hg source term experiment for the APT/SILC target

    International Nuclear Information System (INIS)

    Experiments were performed to measure the fraction of mercury inventory released when droplets of molten lead, doped with a known concentration of mercury, fall through a controlled environment. The temperature of molten droplets ranged from 335 C to 346 C, and the concentration of mercury in the droplets ranged from 0.2 mass % to 1.0 mass %. The environment consisted of an air stream, at a temperature nominally equal to the melt temperature, and moving vertically upwards at a velocity of 10 cm/s. Direct observations and chemical analysis showed that no mercury was released from the molten droplets. Based upon the experimental results, it is concluded that no mercury vapor is likely to be released from the potentially molten source rod material in the APT-SILC Neutron Source Array to the confinement atmosphere during a postulated Large Break Loss Of Coolant Accident scenario leading to the melting of a fraction of the source rods

    AIM: To assess the reliability and validity of the translated version of Nepean Dyspepsia Index (NDI) in Chinese patients with documented functional dyspepsia (FD).METHODS: The translation process included forward translation, back translation, pretest and cross-cultural adaptation. Reliability and validity of the translated version were examined by asking 300 subjects to complete the Chinese version of the NDI. The mean age of subjects was 39.24 years and 68.7% of the subjects were women. Internal consistency analysis with Cronbach's α was performed to test the reliability. Correlation analysis was used to assess the content validity. Factor analysis and structural equation models were used to assess the construct validity.RESULTS: The Cronbach's α coefficients ranged 0.833-0.960, well above the acceptable level of 0.70. Correlation analysis showed that each item had a strong correlation with the corresponding domain, but a weak correlation with other domains. Confirmatory factor analysis indicated that the comparative fit index was 0.94, higher than the acceptable level of 0.90.CONCLUSION: The Chinese version of the NDI is a reliable and valid scale for measuring health-related quality of life and disease severity in Chinese patients with FD.

    This discussion of China focuses on the following: the people; geography; history (early history, 20th century China, the People's Republic of China; the "Great Leap Forward" and the Sino Soviet Split, the Cultural Revolution, and Mao's death and present directions); government (state structure, Chinese Communist Party, and legal system); education; economy; foreign relations; defense; and relations between China and the US. As of 1982, China's population totaled just over 1.008 billion with an annual growth rate of 1.5%. Life expectancy is 68 years. Government authorities endorsed birth control in the 1950s, played it down in 1958, and began to promote it again in 1962. The present family planning program began in the early 1970s and has become more fully mobilized since 1979. The largest ethnic group is the Han Chinese, who constitute 93.3% of the total population. The People's Republic of China, located in eastern Asia, is almost as large as the European continent. 2/3 of China's area is mountainous or semidesert; only about 1/10 is cultivated. China is the oldest continuous major world civilization with records dating back about 3500 years. Mao's death in September 1976 removed a towering figure from Chinese politics and set off a scramble for succession. The post 11th Party Congress leadership has emphasized economic development and renounced the mass political movements of prior years. Important educational reforms were made in early 1978. Since 1979, the Chinese leadership has moved toward more pragmatic positions in almost all fields. The Chinese government has always been subordinate to the Chinese Communist Party (CCP), its role being to implement party policies. The primary instruments of state power are the State Council, an executive body corresponding to a cabinet, and the NPC, a legislative body. China has made impressive progress in primary education since 1949. About 93% of eligible children are enrolled in 1st grade, though only 65% finish primary

    This paper reports on the reason for China's future nuclear policy. First, assuming a continued decline in superpower influence, China's focus will be on regional issues. The policies of Japan, the NICs and other Chinese neighbors will be more relevant than those of the superpowers. Second, Chinese domestic politics will have to resume the road to reform. A more unstable and suspicious Chinese leadership will perceive a more hostile and unstable world. Even when China was on the path to reform, its foreign relations were not always peaceful. However, it would be wrong to suggest that even a more xenophobic and unstable Chinese leadership would necessarily expand China's nuclear capability or lead China into a major war. Even at the height of the Cultural Revolution, Chinese foreign policy was careful, nuclear proliferation was avoided and crises were well-managed. Still China's basic domestic and foreign policy needs will likely remain unfulfilled for the foreseeable future. Furthermore, although the East Asian balance of power may not appear to be particularly dangerous at present, there is enough uncertainty to ensure that China remains a nuclear power and a maverick one at that at least in the near term

    The rapid development of computer technologies has given rise to the increase of open source web-based map services such as OpenStreetMap, a global vector data created by volunteers for free use. There is a concern about the quality and usability of the OpenStreetMap data because the volunteers that contribute the data generally lack the sufficient cartographic training. This paper focuses on the data quality analysis method for OpenStreetMap. A model for usability evaluation has been proposed. A benchmark between OpenStreetMap data and the 1:10 000 topographic data in some areas of China has been done to verify the proposed model, and the method proves to be effective.

  2. Validity of the Bouchet's complementary relationship at 102 observatories across China

    Bouchet in 1963 hypothesized that for large homogeneous land surface with minimum advection of heat and moisture, there exists a 1:1 complementary relationship of potential and actual evaporation coupled through land-atmosphere feedbacks. The complementary relationship has been widely used to estimate regional actual evaporation and explain the pan evaporation paradox. We examine the stan-dardized potential evaporation (potential evaporation divided by wet environment evaporation) at 102 observatories at different elevations across China. Generally, the relationship is appropriate at the low elevations (<1000 m). With the increase of elevation, vapor transfer power becomes much less than radiation energy budget because of lower vapor pressure deficit and stronger global solar radiation. As a result, at the high elevations (over 1000 m), the excess energy resulted by limited moisture availability is not enough to be converted into drying power of the air. This result suggests that the complementary relationship is asymmetric at the high elevations.

    Full Text Available The 14-item Chalder Fatigue Scale (CFS is widely used, while the 11-item version is seldom to be found in current research in mainland China. The objectives of the present study is to compare the reliability and construct validity between these two versions and to confirm which may be better for the mainland Chinese setting. Based on a cross-sectional health survey with a constructive questionnaire, 1887 individuals aged 18 years or above were selected. Socio-demographic, health-related, gynecological data were collected, and 11-item and 14-item Chalder Fatigue Scale (CFS were used to assess fatigue. Confirmatory factor analysis and exploratory structural equation modeling (ESEM were performed to test the fit of models of the two versions. Confirmatory factor analysis of the two versions of CFS did not support the two-factor theorized models. In addition, a three-factor ESEM model of the 11-item version, but not the 14-item version, showed better factor structure and fitness than the other models examined. Both the versions had good internal consistency reliability and a satisfactory internal consistency (Ω = 0.78–0.96, omega coefficient indicates the internal consistency reliability was obtained from the optimal model. This study provided evidence for satisfactory reliability and structural validity for the three-factor model of the 11-item version, which was proven to be superior to the 14-item version for this data.

    InDels are short-length polymorphisms characterized by low mutation rates, high inter-population diversity, short amplicon strategy and simplicity of laboratory analysis. This work describes the developmental validation of an X-InDels panel amplifying 18 bi-allelic markers and Amelogenin in one single PCR system. Developmental validation indicated that this novel panel was reproducible, accurate, sensitive and robust for forensic application. Sensitivity testing of the panel was such that a full profile was obtainable even with 125 pg of human DNA with intra-locus balance above 70%. Specificity testing was demonstrated by the lack of cross-reactivity with a variety of commonly encountered animal species and microorganisms. For the stability testing in cases of PCR inhibition, full profiles have been obtained with hematin (≤1000 μM) and humic acid (≤150 ng/μL). For the forensic investigation of the 18 X-InDels in the HAN population of China, no locus deviated from the Hardy–Weinberg equilibrium and linkage disequilibrium. Since they are independent from each other, the CDPfemale was 0.999999726 and CDPmale was 0.999934223. The forensic parameters suggested that this X-Indel panel is polymorphic and informative, which provides valuable X-linked information for deficient relationship cases where autosomal markers are uninformative.

    Daily increment validation in fish otolith is fundamental to studies on fish otolith microstructure, age determination and life history traits, and thus is critical for species conservation and fishery management. However, it has never been done for Schizothoracine fish, which is the dominant component of fish fauna in the Tibetan Plateau. This study validated the daily increment formation of Gymnocypris selincuoensis, as a representative of Schizothoracine fish, by monitoring the growth of hatchery-reared larvae group and wild-caught post-yolk-sac larvae group under controlled experiments. The results from monitoring the hatchery-reared larvae group showed that sagittae and lapilli were found in yolk-sac larvae, and formed 5-7 days before hatching, but asterisci were not found until 11 days post-hatching. The first increment in sagittae and lapilli was formed in the first day after hatching. The daily periodicity of increment formation was examined and confirmed in sagittae and lapilli of both larvae groups. However, sagittae were better for age determination than lapilli for larvae at earlier days. For larval G. selincuoensis older than 50 days, lapilli were the only otolith pair suitable for larvae daily age determination. This study validated the daily increment formation in Schizothoracine fish for the first time has primary implications to other fishes from this subfamily. PMID:26380660

    Full Text Available This study evaluates the performance of four evapotranspiration methods (Priestley-Taylor, Penman-Monteith, Hargreaves and Makkink of differing complexity in a semi-arid environment in north China. The results are compared to observed water vapour fluxes derived from eddy flux measurements. The analysis became necessary after discharge simulations using an automatically calibrated version of the Soil and Water Assessment Tool (SWAT failed to reproduce runoff measurements. Although the study area receives most of the annual rainfall during the vegetation period, high temperatures can cause water scarcity. We investigate which evapotranspiration method is most suitable for this environment and whether the model performance of SWAT can be improved with the most adequate evapotranspiration method.

    The evapotranspiration models were tested in two consecutive years with different rainfall amounts. In general, the simple Hargreaves and Makkink equations outmatch the more complex Priestley-Taylor and Penman-Monteith methods, although their performance depended on water availability. Effects on the quality of SWAT runoff simulations, however, remained minor. Although evapotranspiration is an important process in the hydrology of this steppe environment, our analysis indicates that other driving factors still need to be identified to improve SWAT simulations.

    Perceived stress while driving may affect how critical driving events are handled. The current study validates a Chinese version of the Driver Stress Inventory (DSI) and explores its correlation with dangerous driving behaviors and gender. A sample of 246 drivers completed the Chinese version of the DSI and the Driver Behavior Questionnaire (DBQ). We also evaluated specific sociodemographic variables and traffic violations (including speeding, violating traffic signs or markings, driving while intoxicated, running a red light, and incurring penalty points). A confirmatory factor analysis (CFA) verified the DSI's internal structure. The DSI was also validated using questionnaires related to the DBQ, self-reported traffic accidents and violations, and sociodemographic characteristics. First, all of the DSI dimensions were moderately or weakly correlated with the DBQ subscales. Second, aggression, hazard monitoring and fatigue were weakly correlated with minor accidents. Third, drivers who had sped and violated traffic signs during the previous three years reported higher aggression and thrill seeking, while drivers who had violated traffic signs or markings during the previous three years reported decreased hazard monitoring compared with non-offenders. Finally, there were significant gender differences in driver stress. The Chinese version of the DSI will be useful for classifying and diagnosing drivers who may be at an increased risk for stress reactions. PMID:26642077

    Full Text Available BACKGROUND: This study aims to evaluate the reproducibility and validity of a food frequency questionnaire (FFQ developed for female adolescents in the Suihua area of North China. The FFQ was evaluated against the average of 24-hour dietary recalls (24-HRs. METHODOLOGY/PRINCIPAL FINDINGS: A total of 168 female adolescents aged 12 to 18 completed nine three consecutive 24-HRs (one three consecutive 24 HRs per month and two FFQs over nine months. The reproducibility of the FFQ was estimated using intraclass correlation coefficients (ICCs, and its relative validity was assessed by comparing it with the 24-HRs. The mean values of the 24-HRs were lower than those of the FFQs, except for protein (in FFQ1 and iron (in FFQ2. The ICCs for all nutrients and food groups in FFQ1 and FFQ2 were moderately correlated (0.4-0.8. However, all the ICCs decreased after adjusting for energy. The weighted κ statistic showed moderate agreement (0.40-0.6 for all nutrients and food groups, except for niacin and calcium, which showed poor agreement (0.35. The relative validity results indicate that the crude Spearman's correlation coefficients of FFQ1 and the 24-HRs ranged from 0.41 (for Vitamin C to 0.65 (for fruit. The coefficients of each nutrient and food group in FFQ2 and the 24-HRs were higher than those in FFQ1 and the 24-HRs, indicating good correlation. Although all energy-adjusted Spearman's correlation coefficients were lower than the crude coefficients, de-attenuation to correct for intra-individual variability improved the correlation coefficients. The weighted κ coefficients of nutrients and food groups ranged from 0.32 for beans to 0.52 for riboflavin in FFQ1 and the 24-HRs, and 0.32 for Vitamin C to 0.54 for riboflavin in FFQ2 and the 24-HRs. CONCLUSION: The FFQ developed for female adolescents in the Suihua area is a reliable and valid instrument for ranking individuals within this study.

    SummaryThe latent heat of evapotranspiration (ET) plays an important role for water resource management in water scarcity areas. Compared to the water balance method or to in situ measurements, an operational integrated monitoring method of regional surface ET from remote sensing data is a potentially useful approach to achieve water saving. This study presents new algorithms for the aerodynamic roughness length for complex landscape, for gap filling for cloud days, and for data fusion at different resolutions, based on the Penman-Monteith equation. It also presents an improved algorithm for ET calculation with remotely sensed data for clear days. Algorithms were integrated into the ETWatch. The research objective was to present the enhanced features of the ETWatch algorithm and its validation in the 320,000 km2 Hai Basin in Northern China. This area faces serious over-exploitation of groundwater. ET was modeled and extensive field campaigns were done to collect data on soil moisture depletion, lysimeter measurements, eddy covariance measurements, and water balance calculations at diverse landscapes. The overall deviation for individual fields on a seasonal basis was 12% and decreased to 6% for an annual cycle. For larger areas, the deviation was 3% for an annual cycle. These levels of deviation are within the error bands for in situ measurements. The study concludes that data sets from ETWatch are able to aid consumptive water use reduction management in the study area.

    An enthalpy-based frozen soil model was developed for the simulation of water and energy transfer in cold regions. To simulate the soil freezing/thawing processes stably and efficiently, a three-step algorithm was applied to solve the nonlinear governing equations: (1) a thermal diffusion equation was implemented to simulate the heat conduction between soil layers; (2) a freezing/thawing scheme used a critical temperature criterion to judge the phase status and introduced enthalpy and total water mass into freezing depression equation to represent ice formation/melt and corresponding latent heat release/absorption; and (3) a water flow scheme was employed to describe the liquid movement within frozen soil. In addition, a parameterization set of hydraulic and thermal properties was updated by considering the frozen soil effect. The performance of the frozen soil model was validated at point scale in a typical mountainous permafrost basin of China. An ice profile initialization method is proposed for permafrost modeling. Results show that the model can achieve a convergent solution at a time step of hourly and a surface layer thickness of centimeters that are typically used in current land surface models. The simulated profiles of soil temperature, liquid water content, ice content and thawing front depth are in good agreement with the observations and the characteristics of permafrost. The model is capable of continuously reproducing the diurnal and seasonal freeze-thaw cycle and simulating frozen soil hydrological processes.

The RPQ was administered to 11 year-old participants in the China Jintan Child Cohort Study, a population-based longitudinal study of 1352 children. Similar to other studies, a two-factor solution with one reactive and one proactive subscale best described the data. Overall, the Chinese version of the RPQ had good construct validity, internal consistency, and test-retest reliability. These findings suggest that the RPQ is psychometrically similar when administered to children and adolescents in the United States and in China and need not be modified to measure aggressive behavior in Chinese samples.

We determine the tropospheric vertical column densities (VCDs), near surface concentrations and vertical profiles of aerosols, NO2, SO2, HCHO from the MAX-DOAS observations using the optimal estimation profile retrieval algorithm (refered to as "PriAM"). We verified the results by comparing them with results from independent techniques, such as sun photometer (AERONET), a visibility meter and a long-path DOAS instrument. We acquire the cloud and aerosol conditions using a cloud classification scheme based on the MAX-DOAS observations (Wang et al., AMTD, 2015). Based on the obtained results, we characterize the effect of the clouds on the trace gas and aerosol profiles retrieved from MAX-DOAS. Then we characterize the diurnal, annual and weekly variations of the trace gases and aerosols and validate the tropospheric trace gas VCDs derived from the Ozone Monitoring instrument (OMI) on the Aura satellite platform as well as the model results from the IMAGES, CHIMERE and Lotos-Euros models and analyse the agreement depending on the cloud and aerosol conditions. Besides the direct comparison with the satellite data, we also use the trace gas and aerosol profiles derived from MAX-DOAS to recalculate the air mass factor (AMF) for the satellite observations and to evaluate the corresponding improvement of the satellite VCDs. In some periods with strong aerosol pollution, we evaluate the

    An effective population-based screening tool is needed to identify possible cases of Developmental Coordination Disorder (DCD) among preschool children in mainland China. We examined the psychometric properties of the DCD questionnaire'07 (DCDQ'07) in Chinese children aged 4-6. A total of 3316 children from 10 nursery schools were involved in the study. Internal consistency and test-retest reliability of the DCDQ'07 were estimated using Cronbach's alpha, item-total correlation and intraclass correlation co-efficient (ICC). The construct validity was evaluated using the exploratory and confirmatory factor analysis. Receiver operating characteristic (ROC) analysis was used to measure the accuracy of the DCDQ'07. The results showed that both internal consistency (Cronbach's alpha value of all items were above 0.85) and test-retest reliability (ICCs of 13 items and subscales were above 0.9) were excellent. Confirmatory factor analysis showed that each goodness-of-fit indices of the 3-factor model was above 0.9, indicating a satisfactory fit of the data to the model. Area under the ROC curve was comparatively small (0.641). With the exception of construct validity in younger children (4 years old) and discriminative validity, the Chinese version of the DCDQ'07 achieves satisfactory reliability and construct validity in mainland China. Nevertheless, the questionnaire should be not used in younger children, and further studies are needed to explore the use of Little DCD-Q in Chinese preschool children. PMID:26513741

    Full Text Available A challenge for the quantitative analysis of tropospheric nitrogen dioxide (NO2 column data from satellite observations is posed partly by the lack of satellite-independent observations for validation. We performed such observations of the tropospheric NO2 column using the ground-based Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS technique in the North China Plain (NCP from 29 May to 29 June, 2006. Comparisons between tropospheric NO2 columns measured by MAX-DOAS and the Ozone Monitoring Instrument (OMI onboard the Aura satellite indicate that OMI data (the standard product, version 3 over NCP may have a positive bias of 1.6×1015 molecules cm−2 (20%, yet within the uncertainty of the OMI data. Combining these results with literature validation results for the US, Europe, and Pacific Ocean suggests that a bias of +20%/−30% is a reasonable estimate, accounting for different regions.

  1. Using GOCI Retrieval Data to Initialize and Validate a Sediment Transport Model for Monitoring Diurnal Variation of SSC in Hangzhou Bay, China

    2016-03-01

    Full Text Available The diurnal variation of the suspended sediment concentration (SSC in Hangzhou Bay, China has been investigated using remotely-sensed SSC derived from the Geostationary Ocean Color Imager (GOCI in combination with a coupled hydrodynamic-ecological model for regional and shelf seas (COHERENS. The SSC maps were inferred through a UV-AC atmospheric correction algorithm and an empirical inversion algorithm from the GOCI Level-1B data. The sediment transport model was initialized from maps of the GOCI-derived SSC and the model results were validated through a comparison with remotely-sensed data. The comparison demonstrated that the model results agreed well with the observations. The relationship between SSC distribution and hydrodynamic conditions was analyzed to investigate the sediment transport dynamics. The model’s results indicate that the action of tidal currents dominate the sediment deposition and re-suspension in the coastal waters of the East China Sea. This is especially the case in Hangzhou Bay where the tidal currents are strongest. The satellite-derived sediment data product can not only dramatically improve the specification of the initial conditions for the sediment model, but can also provide valuable information for the model validation, thereby improving the model’s overall performance.

    Full Text Available According to the preliminary concept of the high-level radioactive waste (HLW repository in China, a large-scale mock-up facility, named China-Mock-Up was constructed in the laboratory of Beijing Research Institute of Uranium Geology (BRIUG. A heater, which simulates a container of radioactive waste, is placed inside the compacted Gaomiaozi (GMZ-Na-bentonite blocks and pellets. Water inflow through the barrier from its outer surface is used to simulate the intake of groundwater. The numbers of water injection pipes, injection pressure and the insulation layer were determined based on the numerical modeling simulations. The current experimental data of the facility are herein analyzed. The experiment is intended to evaluate the thermo-hydro-mechano-chemical (THMC processes occurring in the compacted bentonite-buffer during the early stage of HLW disposal and to provide a reliable database for numerical modeling and further investigation of engineered barrier system (EBS, and the design of HLW repository.

  6. Measuring coverage in MNCH: a validation study linking population survey derived coverage to maternal, newborn, and child health care records in rural China.

    Directory of Open Access Journals (Sweden)

    Li Liu

    Full Text Available BACKGROUND: Accurate data on coverage of key maternal, newborn, and child health (MNCH interventions are crucial for monitoring progress toward the Millennium Development Goals 4 and 5. Coverage estimates are primarily obtained from routine population surveys through self-reporting, the validity of which is not well understood. We aimed to examine the validity of the coverage of selected MNCH interventions in Gongcheng County, China. METHOD AND FINDINGS: We conducted a validation study by comparing women's self-reported coverage of MNCH interventions relating to antenatal and postnatal care, mode of delivery, and child vaccinations in a community survey with their paper- and electronic-based health care records, treating the health care records as the reference standard. Of 936 women recruited, 914 (97.6% completed the survey. Results show that self-reported coverage of these interventions had moderate to high sensitivity (0.57 [95% confidence interval (CI: 0.50-0.63] to 0.99 [95% CI: 0.98-1.00] and low to high specificity (0 to 0.83 [95% CI: 0.80-0.86]. Despite varying overall validity, with the area under the receiver operating characteristic curve (AUC ranging between 0.49 [95% CI: 0.39-0.57] and 0.90 [95% CI: 0.88-0.92], bias in the coverage estimates at the population level was small to moderate, with the test to actual positive (TAP ratio ranging between 0.8 and 1.5 for 24 of the 28 indicators examined. Our ability to accurately estimate validity was affected by several caveats associated with the reference standard. Caution should be exercised when generalizing the results to other settings. CONCLUSIONS: The overall validity of self-reported coverage was moderate across selected MNCH indicators. However, at the population level, self-reported coverage appears to have small to moderate degree of bias. Accuracy of the coverage was particularly high for indicators with high recorded coverage or low recorded coverage but high specificity. The

  7. Tropospheric NO2 column densities deduced from zenith-sky DOAS measurements in Shanghai, China, and their application to satellite validation

    2008-09-01

    Full Text Available Zenith-sky scattered sunlight observations using differential optical absorption spectroscopy (DOAS technique were carried out in Shanghai, China (31.3° N, 121.5° E since December 2006. At this polluted urban site, the measurement provided NO2 total columns in the daytime. Here, we present a new method to extract time series of tropospheric vertical column densities (VCD of NO2 from these observations. The derived tropospheric NO2 VCD is an important quantity for the estimation of emissions and for the validation of satellite observations. Our method makes use of assumptions on the relative NO2 height profiles and on the diurnal variation of the stratospheric NO2 VCD. The influence of these parameters on the retrieved tropospheric NO2 VCD is discussed; for a polluted site like Shanghai, the accuracy of our method is estimated to be <20% for solar zenith angle (SZA lower than 85°. From simultaneously performed long-path DOAS measurement, the NO2 surface concentration at the same site was observed and the corresponding tropospheric NO2 VCD was estimated using the assumed seasonal NO2 profiles in the planetary boundary layer (PBL. By making a comparison between the tropospheric NO2 VCD from zenith-sky and long-path DOAS measurements, it was found that the former provided more realistic information about total tropospheric pollution than the latter, so it's more suitable for satellite data validation than the in situ measurement. A comparison between the tropospheric NO2 VCD from ground-based zenith-sky measurement and SCIAMACHY was also made. Satellite validation for a strongly polluted area is highly needed, but exhibits also a great challenge. Our comparison showed good agreement, considering in particular the different spatial resolutions between the two measurements.

    Accurate monitoring of the spatiotemporal distribution and variation of snow cover is important for snowmelt runoff simulation and water resources management especially in mountainous areas. In this work, we develop a snow data assimilation scheme based on Ensemble Kalman Filter (EnKF) algorithm and Common Land Model (CoLM), which can assimilate snow cover fraction (SCF) products from the Moderate resolution imaging Spectroradiometer (MODIS) into CoLM for improving snow depth (SD) and snow cover area simulations. An empirical model between SD and SCF has been built based on MODIS SCF and snow depth observations at meteorological stations located in study area, which is used as observation operator in snow data assimilation scheme. The assimilation experiment is conducted during 2004-2007, in Xingjiang province, west China. The preliminary assimilation results are very promising and show that the assimilation of SCF could significantly improve the CoLM capability of simulating snow cover area and snow depth. The assimilation results are more closer to those of observations, which have more reasonable and reliable snow accumulation and melting trends throughout the snow season. After assimilating MODIS SCF observations, the Root Mean Square Error (RMSE) and Mean Bias error (MBE) of snow cover or snow depth are significantly reduced compared to the results without assimilation.

    An extraordinary dust event over Beijing (April 2006) was followed by a synergy of lidar, Sun photometric and satellite measurements. Extreme aerosol optical depth (AOD) values (1-4) were measured by AERONET and MODIS over Beijing. The size distribution of the particles remained close to 2.5 μm and the single scattering albedo was around 0.92 +/- 0.5 (440 nm). Coarse particles contributed to more than 60-80% to the AOD values, indicating the presence of very large particles (Ångström exponent DREAM forecast model was applied for the accurate description of the dust event evolution. Ground-truth data were used for the validation of DREAM over the Beijing area.

    Full Text Available Model calibration is essential for hydrologic modeling of large watersheds in a heterogeneous mountain environment. Little guidance is available for model calibration protocols for distributed models that aim at capturing the spatial variability of hydrologic processes. This study used the physically-based distributed hydrologic model, MIKE SHE, to contrast a lumped calibration protocol that used streamflow measured at one single watershed outlet to a multi-site calibration method which employed streamflow measurements at three stations within the large Chaohe River basin in northern China. Simulation results showed that the single-site calibrated model was able to sufficiently simulate the hydrographs for two of the three stations (Nash-Sutcliffe coefficient of 0.65–0.75, and correlation coefficient 0.81–0.87 during the testing period, but the model performed poorly for the third station (Nash-Sutcliffe coefficient only 0.44. Sensitivity analysis suggested that streamflow of upstream area of the watershed was dominated by slow groundwater, whilst streamflow of middle- and down- stream areas by relatively quick interflow. Therefore, a multi-site calibration protocol was deemed necessary. Due to the potential errors and uncertainties with respect to the representation of spatial variability, performance measures from the multi-site calibration protocol slightly decreased for two of the three stations, whereas it was improved greatly for the third station. We concluded that multi-site calibration protocol reached a compromise in term of model performance for the three stations, reasonably representing the hydrographs of all three stations with Nash-Sutcliffe coefficient ranging from 0.59–072. The multi-site calibration protocol applied in the analysis generally has advantages to the single site calibration protocol.

    Hoarding disorder, newly included as a separate diagnostic entity in the Obsessive-Compulsive and Related Disorders section of DSM-5, has been reported to have significantly different symptoms and etiology than obsessive-compulsive disorder (OCD). However, the validity of this new diagnosis in China – where the storing of possessions is sanctioned and normalized – remains to be proven. We considered available data about pathological hoarding in East Asia and found the condition to be relatively common and symptomatically similar to that reported in western countries. We conclude that the ‘Hoarding Disorder’ diagnosis defined in DSM-5 is a valid clinical entity in China, though when making the diagnosis clinicians must take care to differentiate pathological hoarding that is distressing to the individual and significantly interferes with social and occupational functioning from culturally sanctioned thriftiness that is not associated with either distress or social dysfunction.%概述:囤积障碍(hoarding disorder),作为新近被纳入DSM-5强迫症和相关障碍部分的一个独立疾病,与强迫症(obsessive-compulsive disorder, OCD)相比具有明显不同的症状和病因。然而,在中国,人们认可储藏个人财物并认为这是正常的,这种新的诊断方法在中国的效度还有待证明。我们研究了东亚地区有关病理性囤积的可用数据,并发现囤积是比较常见的情况,而且出现的症状也类似于西方国家的报道。我们认为, DSM-5中定义的“囤积障碍”在中国是一种合理的临床实体,虽然临床医生在作出该诊断时必须小心区分病理性囤积与文化上所认可的节俭,前者令患者非常痛苦并且明显妨碍其社会和职业功能,而后者与痛苦或社交障碍都不相关的。

    Full Text Available Validation and performance evaluations are beneficial for developing methods that estimate the remotely sensed land surface temperature (LST. However, such evaluations for Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER data are rare. By selecting the middle reach of the Heihe River basin (HRB, China, as the study area, the atmospheric correction (AC, mono-window (MW, single-channel (SC, and split-window (SW methods were evaluated based on in situ measured LSTs. Results demonstrate that the influences of surface heterogeneity on the validation are significant in the study area. For the AC, MW, and SC methods, the LSTs estimated from channel 13 are more accurate than those from channel 14 in general cases. When the in situ measured atmospheric profiles are available, the AC method has the highest accuracy, with a root-mean squared error (RMSE of about 1.4–1.5 K at the homogenous oasis sites. In actual application without sufficient in situ measured inputs, the MW method is highly accurate; the RMSE is around 1.5–1.6 K. The SC method systematically overestimates LSTs and it is sensitive to error in the water vapor content. The two SW methods are simple to use but their performances are limited by accuracies, revealed by the simulation dataset. Therefore, when the in situ atmospheric profiles are available, the AC method is recommended to generate reliable ASTER LSTs for modeling the eco-hydrological processes in the middle reach of the HRB. When sufficient in situ measured inputs are not available, the MW method can be used instead.

    2016-02-01

    Full Text Available The 3 km Dark Target (DT aerosol optical depth (AOD products, 10 km DT and Deep Blue (DB AOD products from the Collection 6 (C6 product data of Moderate Resolution Imaging Spectroradiometer (MODIS are compared with Sun-sky Radiometer Network (SONET measurements at Song Mountain in central China, where ground-based remote sensing measurements of aerosol properties are still very limited. The seasonal variations of AODs are significant in the Song Mountain region, with higher AODs in spring and summer and lower AODs in autumn and winter. Annual mean AODs (0.55 µm vary in the range of 0.5–0.7, which indicates particle matter (PM pollutions in this mountain region. Validation against one-year ground-based measurements shows that AOD retrievals from the MODIS onboard Aqua satellite are better than those from the Terra satellite in Song Mountain. The 3 km and 10 km AODs from DT algorithms are comparable over this region, while the AOD accuracy of DB algorithm is relatively lower. However, the spatial coverage of DB products is higher than that of 10 km DT products. Moreover, the optical and microphysical characteristics of aerosols at Song Mountain are analyzed on the basis of SONET observations. It suggests that coarse-mode aerosol particles dominate in spring, and fine-mode particles dominate in summer. The aerosol property models are also established and compared to aerosol types used by MODIS algorithm.

    Previous studies have suggested the cross-cultural generalizability of a 5-factor structure for personality traits. In this article, we analyzed the utility of 2 versions (100-item and 50-item) of the IPIP Big-Five factor markers in both heterosexual (N = 633) and homosexual (N = 437) samples in China. Factor analysis within versions showed that both versions of these IPIP measures showed clear 5-factor orthogonal structures that were nearly identical to the American structure in both subject samples. The reliabilities of the five factors were quite high except for the 50-item measure of Agreeableness. The part-whole correlations between the 100-item and 50-item factors were high, as were the factor congruence coefficients between the heterosexual and the homosexual samples. Both versions of the IPIP Big-Five factor markers were strongly correlated with the scales from the Big Five Inventory (BFI: John, Donahue & Kentle, 1991), thus providing some concurrent validation in a Chinese context.

    This paper has conducted a short-term national-scale assessment of flood hazards in China based on the theory of natural disaster risks and by means of the powerful spatial analytic tool of GIS, as well as the normalization and analytic hierarchy process. The pre- cipitation of the current day and last three days, topographic elevation, topographic stand- ard deviation, network of rivers and lakes respectively were extracted as assessment factors, the methods of flood hazard factors computation and the models of flood hazard inde xes were advanced, as well as hazard assessment model was built for the national-scale flood hazard. Combined with disasters records, analysis of the minimum and maximum of hazard indexes by statistical method, the flood hazards are divided into four levels: high, medium, low and zero by dividing points of 0.3, 0.45 and 0.6, respectively. Then the model of short-term flood hazard assessment was built and used for a flood hazard assessment on September 14, 2009. It was applied for real-time flood events from June 18 to September 16, 2009 on daily basis. Finally, this paper puts forward the result validation method of flood hazard assessment based on the official report of disaster data. It collects the data from official report of disasters to build the disaster spatial database for the same period of the flood season in 2009, and validates the flood hazard assessment results in the point of view of quantity and area from both county-based and district-based validation u- nit. And the result shows that the rate of correct assessment (i. e. both the hazards and disasters occurrence) is above 65% for counties as the assessment unit and above 84% for districts as the assessment unit in the point of view of quantity. The validation result reveals that short-term national flood hazard assessment conforms basically to the actual disaster data. This model has been successfully applied to the forecast of flood hazards by the Disaster

    North China (NC), namely Huabei in Chinese, is one of the most severely polluted regions in China, and the air pollution issues in this region have received a worldwide attention. We performed ground-based Multi Axis Differential Absorption Spectroscopy (MAX-DOAS) measurements at Gucheng, (39°08‧N, 115°40‧E), a rural site of North China about 110 km southwest of Beijing, from September 2008 to September 2010. The tropospheric vertical column densities (VCDs) of NO2 and SO2 were retrieved using the so-called geometric approximation. The results show that the tropospheric NO2 and SO2 VCDs over NC have nearly the same seasonal variation pattern, with the maximum in winter and minimum in summer, while their diurnal variations are different. We also compared the tropospheric NO2 and SO2 VCDs from our MAX-DOAS measurements with several products of corresponding OMI (Ozone Monitoring Instrument) satellite observations. While in summer good agreement is found, the satellite observations systematically underestimate the tropospheric NO2 in winter over the polluted rural area of NC, probably mostly due to the so called aerosol shielding effect. In contrast, for SO2 no such clear conclusion can be drawn, probably owing to the larger uncertainties from MAX-DOAS and in particular satellite retrievals. This indicates that improvements of the retrieval algorithm for MAX-DOAS and off-line corrections of satellite measurements for the tropospheric SO2 VCDs should be given more emphasis in the future.

We describe normative data, reliability and validity of the Chinese translation of the SDQ (parent, teacher and self report versions in a large group of children from Shanghai. Methods The SDQ was administered to the parents and teachers of students from 12 of Shanghai's 19 districts, aged between 3 and 17 years old, and to those young people aged between 11 and 17 years. Retest data was collected from parents and teachers for 45 students six weeks later. Data was analysed to describe normative scores, bandings and cut-offs for normal, borderline and abnormal scores. Reliability was assessed from analyses of internal consistency, inter-rater agreement, and temporal stability. Structural validity, convergent and discriminant validity were assessed. Results Full parent and teacher data was available for 1965 subjects and self report data for 690 subjects. Normative data for this Chinese urban population with bandings and cut-offs for borderline and abnormal scores are described. Principle components analysis indicates partial agreement with the original five factored subscale structure however this appears to hold more strongly for the Prosocial Behaviour, Hyperactivity – Inattention and Emotional Symptoms subscales than for Conduct Problems and Peer Problems. Internal consistency as measured by Cronbach's α coefficient were generally low ranging between 0.30 and 0.83 with only parent and teacher Hyperactivity – Inattention and teacher Prosocial Behaviour subscales having α > 0.7. Inter-rater correlations were similar to those reported previously (range 0.23 – 0

    Full Text Available Abstract Background Health related quality of life (HRQOL has increasingly emphasized on cancer patients. The psychometric properties of the standard Chinese version of the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30 (EORTC QLQ-C30, version 3.0 in brain tumor patients wasn't proven, and there was no baseline HRQOL in brain tumor patients prior to surgery. Methods The questionnaire EORTC QLQ-C30 (version 3.0 was administered at three time points: T1, the first or the second day that patients were hospitalized after the brain tumor suspected or diagnosed by MRI or CT; T2, 1 to 2 days after T1, (T1 and T2 were both before surgery; T3, the day before discharge. Clinical variables included disease histologic types, cognitive function, and Karnofsky Performance Status. Results Cronbach's alpha coefficients for multi-item scales were greater than .70 and multitrait scaling analysis showed that most of the item-scale correlation coefficients met the standards of convergent and discriminant validity, except for the cognitive functioning scale. All scales and items exhibited construct validity. Score changes over peri-operation were observed in physical and role functioning scales. Compared with mixed cancer patients assessed after surgery but before adjuvant treatment, brain tumor patients assessed pre-surgery presented better function and fewer symptoms. Conclusions The standard Chinese version of the EORTC QLQ-C30 was overall a valid instrument to assess HRQOL in brain tumor patients in China. The baseline HRQOL in brain tumor patients pre-surgery was better than that in mixed cancer patients post-surgery. Future study should modify cognitive functioning scale and examine test-retest reliability and response validity.

    Full Text Available We performed MAX-DOAS measurements during the PRiDe-PRD2006 campaign in the Pearl River Delta region 50 km north of Guangzhou, China, for 4 weeks in June 2006. We used an instrument sampling at 7 different elevation angles between 3° and 90°. During 9 cloud-free days, differential slant column densities (DSCDs of O4 (O2 dimer absorptions between 351 nm and 389 nm were evaluated for 6 elevation angles. Here, we show that radiative transfer modeling of the DSCDS can be used to retrieve the aerosol extinction and the height of the boundary layer. A comparison of the aerosol extinction with simultaneously recorded, ground based nephelometer data shows excellent agreement.

    This study evaluates the accuracy of total ozone column derived from Ozone Monitoring Instruments (OMI) with two algorithms: OMI Total Ozone Mapping Spectrometer (OMI-TOMS) and OMI Differential Optical Absorption Spectroscopy (OMI-DOAS), compared to ground-based Brewer and Dobson spectrophotometers located at eight China stations from July 2009 to December 2013, including Xianghe, Kunming, Mt.Waliguan, Lhasa, Taipei, Chengkung, Cape D'Aguilar and Longfengshan. Results showed that the agreement between OMI ozone data and ground-based measurements is excellent. Total ozone columns from both OMI-TOMS and OMI-DOAS data are on average about 1.5% lower than ground-based data. For both OMI ozone data products the SZA dependence of the mean relative differences (RD) between satellite data and the ground-based data is relative obvious when the SZA is larger than 50°. Similar to the SZA, the satellite view zenith angle (VZA) dependence of the mean relative differences (RD) between satellite and ground is relatively markedly when the VZA is smaller than 10° in eight stations. Finally, the dependence of the mean relative differences (RD) (-4.28% to 0.818%) between OMI-DOAS data and ground-based data for the total ozone column is remarkable. While for OMI-TOMS data the dependence is not obvious (the RD value varies from -3.30% to -0.676%).

    Climate change is impacting agro-ecosystems, crops, and farmer livelihoods in communities worldwide. While it is well understood that more frequent and intense climate events in many areas are resulting in a decline in crop yields, the impact on crop quality is less acknowledged, yet it is critical for food systems that benefit both farmers and consumers through high-quality products. This study examines tea (Camellia sinensis; Theaceae), the world's most widely consumed beverage after water, as a study system to measure effects of seasonal precipitation variability on crop functional quality and associated farmer knowledge, preferences, and livelihoods. Sampling was conducted in a major tea producing area of China during an extreme drought through the onset of the East Asian Monsoon in order to capture effects of extreme climate events that are likely to become more frequent with climate change. Compared to the spring drought, tea growth during the monsoon period was up to 50% higher. Concurrently, concentrations of catechin and methylxanthine secondary metabolites, major compounds that determine tea functional quality, were up to 50% lower during the monsoon while total phenolic concentrations and antioxidant activity increased. The inverse relationship between tea growth and concentrations of individual secondary metabolites suggests a dilution effect of precipitation on tea quality. The decrease in concentrations of tea secondary metabolites was accompanied by reduced farmer preference on the basis of sensory characteristics as well as a decline of up to 50% in household income from tea sales. Farmer surveys indicate a high degree of agreement regarding climate patterns and the effects of precipitation on tea yields and quality. Extrapolating findings from this seasonal study to long-term climate scenario projections suggests that farmers and consumers face variable implications with forecasted precipitation scenarios and calls for research on management

    Full Text Available Abstract Background The Pediatric Quality of Life Inventory (PedsQL is widely used instrument to measure pediatric health-related quality of life (HRQOL for children aged 2 to 18 years. The purpose of the current study was to investigate the feasibility, reliability and validity of the Chinese mandarin version of the PedsQL 4.0 Generic Core Scales and 3.0 Cancer Module in a group of Chinese children with cancer. Methods The PedsQL 4.0 Genetic Core Scales and the PedsQL 3.0 Cancer Module were administered to children with cancer (aged 5-18 years and parents of such children (aged 2-18 years. For comparison, a survey on a demographically group-matched sample of the general population with children (aged 5-18 and parents of children (aged 2-18 years was conducted with the PedsQL 4.0 Genetic Core Scales. Result The minimal mean percentage of missing item responses (except the School Functioning scale supported the feasibility of the PedsQL 4.0 Generic Core Scales and 3.0 Cancer Module for Chinese children with cancer. Most of the scales showed satisfactory reliability with Cronbach's α of exceeding 0.70, and all scales demonstrated sufficient test-retest reliability. Assessing the clinical validity of the questionnaires, statistically significant difference was found between healthy children and children with cancer, and between children on-treatment versus off-treatment ≥12 months. Positive significant correlations were observed between the scores of the PedsQL 4.0 Generic Core Scale and the PedsQL 3.0 Cancer Module. Exploratory factor analysis demonstrated sufficient factorial validity. Moderate to good agreement was found between child self- and parent proxy-reports. Conclusion The findings support the feasibility, reliability and validity of the Chinese Mandarin version of PedsQL 4.0 Generic Core Scales and 3.0 Cancer Module in children with cancer living in mainland China.

    We have developed an operational model to simulate water and energy fluxes in the Haihe River Basin (231,800 km2 in size) for the past 28 years. This model is capable of estimating water and energy fluxes of irrigated croplands and heterogeneous grids. The model was validated using actual evapotranspiration (ETa) measured by an eddy covariance system, measured soil moisture in croplands, groundwater level measurements over the piedmont plain and runoff observations in a mountainous catchment. A long-term time series of water and energy balance components were then simulated at a daily time step by integrating remotely sensed information and meteorological data to examine the spatial and temporal distribution and changes in water and energy fluxes in the basin over the past 28 years. The results show that net radiation (Rn) in the mountainous regions is generally higher than that in the plain regions. ETa in the plain regions is higher than that in the mountainous regions mostly because of higher air temperature and larger areas of irrigated farmland. Higher sensible heat flux (H) and lower ETa in the urban areas are possibly due to less vegetation cover, an impervious surface, rapid drainage, and the heat island effect of cities. During the study period, a water deficit continuously occurred in the plain regions because of extensive pumping of groundwater for irrigation to meet the crop water requirements. Irrigation has led to significant groundwater depletion, which poses a substantial challenge to the sustainability of water resources in this basin.

According to random walk hypothesis, by using logarithm dynamic auto-regression model, run test and unit root test, through testing the validity of Shanghai and Shenzhen stock exchange market, it concludes that both have reached to the weak efficiency. But the test cannot prove that the mutual influence between them exists and the prices overlap, it's necessary to justify whether the two markets are efficiency jointly. Through the Johansen cointegration test and the Granger causality test, it can be proved that the returns of Shanghai has a slight role in prediction on the Shenzhen, however, there is no long-term and harmonious relationship between Shanghai and Shenzhen stock markets. Based on this, the two market are weak efficiency jointly.

    2007-01-01

    The four experiments, ALICE, ATLAS, CMS and LHCb are currently under construction at CERN. They will study the products of proton-proton collisions at the Large Hadron Collider. All experiments are equipped with sophisticated tracking systems, unprecedented in size and complexity. Full exploitation of both the inner detector and the muon system requires an accurate alignment of all detector elements. Alignment information is deduced from dedicated hardware alignment systems and the reconstruction of charged particles. However, the system is degenerate which means the data is insufficient to constrain all alignment degrees of freedom, so the techniques are prone to converging on wrong geometries. This deficiency necessitates validation and monitoring of the alignment. An exhaustive discussion of means to validate is subject to this document, including examples and plans from all four LHC experiments, as well as other high energy experiments.

    SANSMIC is solution mining software that was developed and utilized by SNL in its role as geotechnical advisor to the US DOE SPR for planning purposes. Three SANSMIC leach modes - withdrawal, direct, and reverse leach - have been revalidated with multiple test cases for each mode. The withdrawal mode was validated using high quality data from recent leach activity while the direct and reverse modes utilized data from historical cavern completion reports. Withdrawal results compared very well with observed data, including the location and size of shelves due to string breaks with relative leached volume differences ranging from 6 - 10% and relative radius differences from 1.5 - 3%. Profile comparisons for the direct mode were very good with relative leached volume differences ranging from 6 - 12% and relative radius differences from 5 - 7%. First, second, and third reverse configurations were simulated in order to validate SANSMIC over a range of relative hanging string and OBI locations. The first-reverse was simulated reasonably well with relative leached volume differences ranging from 1 - 9% and relative radius differences from 5 - 12%. The second-reverse mode showed the largest discrepancies in leach profile. Leached volume differences ranged from 8 - 12% and relative radius differences from 1 - 10%. In the third-reverse, relative leached volume differences ranged from 10 - 13% and relative radius differences were ~4 %. Comparisons to historical reports were quite good, indicating that SANSMIC is essentially the same as documented and validated in the early 1980's.

    Full Text Available A China that is in a frenzied state of economic boom and potential social instability, which is most vividly represented in its architectural and urban developments, is, I hope I will convince you, ephemeral. A quite different China, perhaps is not so visible as its new buildings and cities, is metaphorically ‘handmade’. I should like to extend the meanings of the handmade to the more stable and long lasting attitudes towards social life, and even mortality. My sources for the second China are partially from literature (not from architecture. With the construction boom since the mid-1990s, mainstream Western architectural journals and galleries have been racing to expose new architecture in China; celebrity Western architects have been winning major commissions in China: the 2008 Beijing Olympic Games is a case in point. The sheer quantity and speed of China’s development, as evidenced in architecture and urbanisation, causes an ‘unbearable lightness of being’ (to paraphrase Milan Kundera. Does all this then suggest that China, as solidified in its buildings and cities, is no longer ‘handmade’ in the sense that memory and a sense of history are redundant (particularly for a country that has a recorded history of more than 5000 years, which have been so lovingly recorded in handmade artefacts? The true meaning of the handmade, which absorbs labour — an ‘honourable labour’ as Joseph Conrad lovingly put it in his Mirror of the Sea, as well as memory, like that of a home, is a static artefact, which harbours our changing emotion, the frailties of human life, and indeed, the growing awareness that comes with time of our mortality: the handmade offers the necessary enshrinement of life’s vulnerability. Let me assure you, the seemingly fast-changing China, as represented in its new architecture and city forms, as well in its frenzied urbanisation and booming economy, is but a smoke screen. It is, in other words, ephemeral. The

    2006-08-01

    Effective management of water resources in arid and semi-arid areas demands studies that cross over the disciplinaries of natural and social sciences. An integrated Hydrological, Ecological and Economical (HEE) modeling system at regional scale has been developed to assess water resources use and ecosystem production in arid and semi-arid areas. As a physically-based distributed modeling system, the HEE modeling system requires various input parameters including those for soil, vegetation, topography, groundwater, and water and agricultural management at different spatial levels. A successful implementation of the modeling system highly depends on how well it is calibrated. This paper presented an automatic calibration procedure for the HEE modeling system and its test in the upper and middle parts of the Yellow River basin. Previous to calibration, comprehensive literature investigation and sensitivity analysis were performed to identify important parameters for calibration. The automatic calibration procedure was base on conventional Monte Carlo sampling method together with a multi-objective criterion for calibration over multi-site and multi-output. The multi-objective function consisted of optimizing statistics of mean absolute relative error (MARE), Nash-Sutcliffe model efficiency coefficient (E NS), and coefficient of determination (R2). The modeling system was calibrated against streamflow and harvest yield data from multiple sites/provinces within the basin over 2001 by using the proposed automatic procedure, and validated over 1993-1995. Over the calibration period, the mean absolute relative error of simulated daily streamflow was within 7% while the statistics R2 and E NS of daily streamflow were 0.61 and 0.49 respectively. Average simulated harvest yield over the calibration period was about 9.2% less than that of observations. Overall calibration results have indicated that the calibration procedures developed in this study can efficiently calibrate

    The assessment of cluster validity plays a very important role in cluster analysis. Most commonly used cluster validity methods are based on statistical hypothesis testing or finding the best clustering scheme by computing a number of different cluster validity indices. A number of visual methods of cluster validity have been produced to display directly the validity of clusters by mapping data into two- or three-dimensional space. However, these methods may lose too much information to corre...

    中国古代逻辑也是研究推理和论证的。推理和论证的主要目的是揭示一个命题为真的原因或理由。推理关系是一种 "必然地得出" 的关系。墨子提出了四种推理模式:"辟"、"侔"、"援"、"推",而且把 "推" 又分为两种 "止",即归纳"止" 式推论和演绎 "止" 式推论。特别地,墨家提出了 "效" 作为判定推理是否有效的标准。%Ancient Chinese logic concerns reasoning and argumentation. The main aim of argumentation is to reveal the reasons for true statements. The relation between the reasons and the statement to be explained is how the truth of the the statement "necessarily comes about"given the reasons. The Mohists advanced four kinds of reasoning pattern: "illustrating (pi,辟)", "parallelizing (mou, 侔)", "adducing (yuan, 援)" and "inferring (tui, 推)". "Inferring"can also be divided into two kinds of "stopping (zhi, 止)", that is to say, inductive and deductive "stopping" inferences. In addition, the Mohists proposed a standard called "xiao (效)" for determining whether or not reasoning is valid.

The low sun angle, and light snow cover highlight a section of the Great Wall, visible as a black line running diagonally through the image from lower left to upper right. The Great Wall is over 2000 years old and was built over a period of 1000 years. Stretching 4500 miles from Korea to the Gobi Desert it was first built to protect China from marauders from the north.This image is located at 40.2 degrees north latitude and 112.8 degrees east longitude.Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. Science team leader; Moshe Pniel of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The primary goal of the ASTER mission is to obtain high-resolution image data in 14 channels over the entire land surface, as well as black and white stereo images. With revisit time of between 4 and 16 days, ASTER will provide the capability for repeat coverage of changing areas on Earth's surface.The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats, monitoring potentially active volcanoes, identifying crop stress, determining cloud morphology and physical properties, wetlands Evaluation, thermal pollution monitoring, coral reef degradation, surface temperature mapping of soils and geology, and measuring surface

  10. Verification and validation methodology of training simulators

    International Nuclear Information System (INIS)

    A full scope training simulator comprising of 109 plant systems of a 300 MWe PWR plant contracted by Pakistan Atomic Energy Commission (PAEC) from China is near completion. The simulator has its distinction in the sense that it will be ready prior to fuel loading. The models for the full scope training simulator have been developed under APROS (Advanced PROcess Simulator) environment developed by the Technical Research Center (VTT) and Imatran Voima (IVO) of Finland. The replicated control room of the plant is contracted from Shanghai Nuclear Engineering Research and Design Institute (SNERDI), China. The development of simulation models to represent all the systems of the target plant that contribute to plant dynamics and are essential for operator training has been indigenously carried out at PAEC. This multifunctional simulator is at present under extensive testing and will be interfaced with the control planes in March 1998 so as to realize a full scope training simulator. The validation of the simulator is a joint venture between PAEC and SNERDI. For the individual components and the individual plant systems, the results have been compared against design data and PSAR results to confirm the faithfulness of the simulator against the physical plant systems. The reactor physics parameters have been validated against experimental results and benchmarks generated using design codes. Verification and validation in the integrated state has been performed against the benchmark transients conducted using the RELAP5/MOD2 for the complete spectrum of anticipated transient covering the well known five different categories.

The authors propose that evaluation be culturally responsive and the evaluation design be rooted in the particular cultural context where an evaluation is conducted. The appropriate use of the participatory rural appraisal (PRA) approach and methods helps generate data that are relevant and meaningful for evaluation purposes in rural China. PMID:25045841

    International Nuclear Information System (INIS)

    The ESCADRE code system (Ensemble de Systems de Codes d'Analyse d'accidents Des Reactors a Eau) is tool designed to help in evaluating the response of nuclear power plants during hypothetical severe accidents. It is an integral code, built with simple engineering models describing major phenomena involved in the accidental sequences; its main objective is to compute the whole sequence, starting from the core uncover right up to the release of fission products outside the plant containment. In the last few years, ESCADRE has been extensively used in France and Eastern countries such as Russia, Hungary, Slovakia, Bulgaria, China, etc...and also modified to match the Russian PWR (WWER) reactors. Since this, ESCADRE has been significantly improved to cope with the needs of French Probabilistic Safety Analysis level 2, which require extensive calculations involving numerous scenarios and parametric studies. A new release, ESCADRE mod 1.1 has been thus developed and is currently used in France and will be soon available for foreign countries. In a first part, new features of ESCADRE mod 1.1 are presented; on the modeling point of view (for example improvement in the core degradation phenomenology description, consideration of Direct Containment Heating phenomena...) and on the mode of use (improved coupling between ESCADRE modules, safety systems management, consideration of events occurring during the accident). A brief description of the new environment of ESCADRE, making this code much more user friendly, is also provided. Second part of the presentation concerns the ESCADRE validation program. The validation is supported by both French and foreign experimental programs. A validation test matrix is presented, showing the experiments used so far for the validation (only the tests for which a validation work has been achieved and documented are mentioned). This validation effort is still in progress. As an illustration, some of the results of this validation work are

  8. Validation: the eluding definition

    International Nuclear Information System (INIS)

    The term 'validation' is featured prominently in the literature on radioactive high-level waste (HLW) disposal. There exists, however, no unique definition of 'validation' although it is generally understood to be related to model testing using experiments. This paper reviews the several definitions of 'validation' and proposes their categorization into three main classes. The first class links validation to the goal of predicting the physical world as faithfully as possible. This view has been criticized as being unattainable and, in any event, unsuitable for setting goals for the safety analyses. Other definitions (Class 2) are strictly operational, and associate validation only to situations where the models can be tested against observational data. In this view, the decision to retain a predictive model for use in safety assessments does not belong to the remit of 'validation'. The third class of definitions focuses, instead, 'validation' on the quality of the decision-making process, which shifts the debate from validation in the observational sense to 'reasonable assurance' and 'confidence building'. In this third view, one cannot determine when a model or a suite of models are actually 'validated'. The lack of consensus on the meaning of 'validation' is linked to its short history as a technical term. The first technical definition dates from the mid-fifties. The term was adopted thereafter in the computer field and elevated to its present status by the computer revolution of the seventies and early eighties. The term has made its appearance in some HLW safety standards only in the late eighties and it is virtually unmentioned in the low-level waste standards for disposal safety. The continued informal use of the term 'validation' in the field of HLW disposal can become cause for endless speculations. The paper proposes either abandoning the use of this term or agreeing to a common definition. (author) 36 refs

    The primary objective for the Model Validation Status Review was to perform a one-time evaluation of model validation associated with the analysis/model reports (AMRs) containing model input to total-system performance assessment (TSPA) for the Yucca Mountain site recommendation (SR). This review was performed in response to Corrective Action Request BSC-01-C-01 (Clark 2001, Krisha 2001) pursuant to Quality Assurance review findings of an adverse trend in model validation deficiency. The review findings in this report provide the following information which defines the extent of model validation deficiency and the corrective action needed: (1) AMRs that contain or support models are identified, and conversely, for each model the supporting documentation is identified. (2) The use for each model is determined based on whether the output is used directly for TSPA-SR, or for screening (exclusion) of features, events, and processes (FEPs), and the nature of the model output. (3) Two approaches are used to evaluate the extent to which the validation for each model is compliant with AP-3.10Q (Analyses and Models). The approaches differ in regard to whether model validation is achieved within individual AMRs as originally intended, or whether model validation could be readily achieved by incorporating information from other sources. (4) Recommendations are presented for changes to the AMRs, and additional model development activities or data collection, that will remedy model validation review findings, in support of licensing activities.

  1. Verification and validation benchmarks.

    Oberkampf, William Louis; Trucano, Timothy Guy

    2007-02-01

    Verification and validation (V&V) are the primary means to assess the accuracy and reliability of computational simulations. V&V methods and procedures have fundamentally improved the credibility of simulations in several high-consequence fields, such as nuclear reactor safety, underground nuclear waste storage, and nuclear weapon safety. Although the terminology is not uniform across engineering disciplines, code verification deals with assessing the reliability of the software coding, and solution verification deals with assessing the numerical accuracy of the solution to a computational model. Validation addresses the physics modeling accuracy of a computational simulation by comparing the computational results with experimental data. Code verification benchmarks and validation benchmarks have been constructed for a number of years in every field of computational simulation. However, no comprehensive guidelines have been proposed for the construction and use of V&V benchmarks. For example, the field of nuclear reactor safety has not focused on code verification benchmarks, but it has placed great emphasis on developing validation benchmarks. Many of these validation benchmarks are closely related to the operations of actual reactors at near-safety-critical conditions, as opposed to being more fundamental-physics benchmarks. This paper presents recommendations for the effective design and use of code verification benchmarks based on manufactured solutions, classical analytical solutions, and highly accurate numerical solutions. In addition, this paper presents recommendations for the design and use of validation benchmarks, highlighting the careful design of building-block experiments, the estimation of experimental measurement uncertainty for both inputs and outputs to the code, validation metrics, and the role of model calibration in validation. It is argued that the understanding of predictive capability of a computational model is built on the level of

    Two validation suites, one for criticality and another for radiation shielding, have been defined and tested for the MCNP Monte Carlo code. All of the cases in the validation suites are based on experiments so that calculated and measured results can be compared in a meaningful way. The cases in the validation suites are described, and results from those cases are discussed. For several years, the distribution package for the MCNP Monte Carlo code1 has included an installation test suite to verify that MCNP has been installed correctly. However, the cases in that suite have been constructed primarily to test options within the code and to execute quickly. Consequently, they do not produce well-converged answers, and many of them are physically unrealistic. To remedy these deficiencies, sets of validation suites are being defined and tested for specific types of applications. All of the cases in the validation suites are based on benchmark experiments. Consequently, the results from the measurements are reliable and quantifiable, and calculated results can be compared with them in a meaningful way. Currently, validation suites exist for criticality and radiation-shielding applications.

  19. Containment Code Validation Matrix

    International Nuclear Information System (INIS)

    The Committee on the Safety of Nuclear Installations (CSNI) formed the CCVM (Containment Code Validation Matrix) task group in 2002. The objective of this group was to define a basic set of available experiments for code validation, covering the range of containment (ex-vessel) phenomena expected in the course of light and heavy water reactor design basis accidents and beyond design basis accidents/severe accidents. It was to consider phenomena relevant to pressurised heavy water reactor (PHWR), pressurised water reactor (PWR) and boiling water reactor (BWR) designs of Western origin as well as of Eastern European VVER types. This work would complement the two existing CSNI validation matrices for thermal hydraulic code validation (NEA/CSNI/R(1993)14) and In-vessel core degradation (NEA/CSNI/R(2001)21). The report initially provides a brief overview of the main features of a PWR, BWR, CANDU and VVER reactors. It also provides an overview of the ex-vessel corium retention (core catcher). It then provides a general overview of the accident progression for light water and heavy water reactors. The main focus is to capture most of the phenomena and safety systems employed in these reactor types and to highlight the differences. This CCVM contains a description of 127 phenomena, broken down into 6 categories: - Containment Thermal-hydraulics Phenomena; - Hydrogen Behaviour (Combustion, Mitigation and Generation) Phenomena; - Aerosol and Fission Product Behaviour Phenomena; - Iodine Chemistry Phenomena; - Core Melt Distribution and Behaviour in Containment Phenomena; - Systems Phenomena. A synopsis is provided for each phenomenon, including a description, references for further information, significance for DBA and SA/BDBA and a list of experiments that may be used for code validation.

    Full Text Available The application of games for behavioral change has seen a surge in popularity but evidence on the efficacy of these games is contradictory. Anecdotal findings seem to confirm their motivational value whereas most quantitative findings from randomized controlled trials (RCT are negative or difficult to interpret. One cause for the contradictory evidence could be that the standard RCT validation methods are not sensitive to serious games’ effects. To be able to adapt validation methods to the properties of serious games we need a framework that can connect properties of serious game design to the factors that influence the quality of quantitative research outcomes. The Persuasive Game Design model [1] is particularly suitable for this aim as it encompasses the full circle from game design to behavioral change effects on the user. We therefore use this model to connect game design features, such as the gamification method and the intended transfer effect, to factors that determine the conclusion validity of an RCT. In this paper we will apply this model to develop guidelines for setting up validation methods for serious games. This way, we offer game designers and researchers handles on how to develop tailor-made validation methods.

    China aims to become an innovation-led nation by 2020, but its leadership is generally sceptical--and oftentimes hostile--to the market forces, open exchange of ideas, and creative destruction that have unlocked innovation in other countries. Instead, Beijing hopes to promote innovation in China through a massive expansion in higher education,…

    Full Text Available In this paper, I respond to the challenge raised against contemporary experimental neurobiology according to which the field is in a state of crisis because of the multiple experimental protocols employed in different laboratories and strengthening their reliability that presumably preclude the validity of neurobiological knowledge. I provide an alternative account of experimentation in neurobiology which makes sense of its experimental practices. I argue that maintaining a multiplicity of experimental protocols and strengthening their reliability are well justified and they foster rather than preclude the validity of neurobiological knowledge. Thus, their presence indicates thriving rather than crisis of experimental neurobiology.

    This paper discusses the past and the status quo of electricity securitization in China. First, the stranded cost securitization in American electricity industry and the ongoing securitization progress in emerging market countries are investigated, which enlightens the way of electricity securitization in China. Through analysis of electricity industry in China, the paper proposes constructive policy suggestions for regulators who intend to prompt securitization to develop electricity infrastructure, and detailed recommendations for companies who plan to raise money at reduced cost. It is concluded that even though it is at the very beginning stage in China, securitization not only provides financing for investment projects, but also speeds up the reform by stranded cost securitization, a novel idea for electricity industry in China.

  3. AREVA in China

    International Nuclear Information System (INIS)

    China has a great need for secure, safe, and economic energy supplies that combat the greenhouse effect and global warming. Since January 2002, China, the most heavily populated country with more than 1.3 billion inhabitants in a territory of 9.5 million km2 (17 times larger than France), has a nuclear capacity of 9 GWe with 11 nuclear plants on line. Forecasts of electricity consumption report a need for 900 to 1,000 GWe per year through 2020, and at this time the country's objective is to increase nuclear generated electricity from 1% to 4% of its total output. This means a need for additional 30 GWe, which is the equivalent of twenty 1,500 MWe reactors. In addition to nuclear power, China is pushing renewable energy. With the passage of the 2005 Renewable Energy Law, China's government imposed a national renewable energy requirement that is expected to boost the use of renewable energy capacity from 10 to 12 percent by 2020, up from 3% in 2003. This law requires power operators to buy electricity from alternative energy providers and gives economic incentives to these providers. Consequently, China is expanding its interests in renewable energy sources including wind and bio-energies, among others. It is in this context that AREVA, a world expert in energy, creates and offers solutions to generate, transmit, and distribute electricity for China. Based on its long experience and global presence, AREVA has become the worldwide leader for nuclear energy in the areas of construction, equipment, and services for nuclear power plants, and for the whole nuclear fuel cycle. AREVA is also a world leader in electrical power-grid equipment and systems. This document presents: China's need for energy; the Sources of China's energy mix; the challenges of China's nuclear program; AREVA's action in supporting China's ambitious nuclear program; the strong opportunities in renewable energy; and the high potential market for AREVA's T and D Division

  6. Sensitivity analysis and validation

    International Nuclear Information System (INIS)

    In the field of performance assessment modelling for high-level radioactive waste disposal in geologic repositories, evaluating model uncertainties is a key factor in estimating radionuclide transport rate and extrapolating thousands of years into the future. Sensitivity and uncertainty analysis is performed to determine the relationships among the input and output variables of a mathematical model through numerical methods. Because post-closure performance assessment relies heavily on models, sensitivity and uncertainty analyses will become an integral part of the model evaluation and validation process. Model validation is also needed to establish the credibility of predictions to the technical community, and to achieve grater public confidence in the long-term safety of a geologic repository. In this paper, the role of sensitivity analysis as a part of near-field performance assessment will be discussed in terms of model validation. A description of the ENTRY (the Engineered Scale Test and Research Facility) project for validation study will also be presented. (au) (17 refs., 5 figs.)

  14. China's power policy

    International Nuclear Information System (INIS)

    Whether the People's Republic of China may develop to an economical super-government in future depends on the amount of power and resources of this land. The security of power supply is in an extremely prominent position in the Agenda of the Chinese government. Under this aspect the author of the contribution under consideration reports on the power policy of China. The main aspects of this contribution are: (a) Trends of power consumption, productions and imports of power; (b) Power political targets, measures and instruments of China; (c) Characteristics, national and international impacts of the power policy of China. Due to the economical activities of the chinese oil industry worldwide as well as due to the increasing dependence from imports of petroleum and natural oil, China becomes a global player. Thus, one may expect an intensification of Beijing's economical activities with an increased military component. Nevertheless, the power policy of China is an important factor in the global competition according to fossil resources. In order to understand the future behaviour of China's power policy, one may have to take notice of the strategies relating the power policy and relating to foreign affairs. Furthermore, trends and problematic areas concerning the securitization of the power supply in the national area have to be observed

    Full Text Available Review of: Judith Shapiro. 2012. China's Environmental Challenges. Cambridge: UK and Malden, MA: Polity Press. Judith Shapiro's latest ambitious work picks up the story of modern China's checkered relationship with the environment at approximately the point where her previous study, Mao's War Against Nature (2001, left off. This latest book sets out to address questions of grave importance to China and to the world. The litany of challenges – poisonous water and toxic air, scarcity of water and other resources, deforestation, soil erosion, loss of biodiversity – seem nearly insurmountable, despite evidence of considerable attention from the Chinese government and from China's public, and despite the rocket-like rise of China's economic power and political influence in the world. Shapiro adds to this list the growing problems with lapses in environmental justice, both within China and passed on to its neighbours and to the countries with which it trades. Not only do growing environmental problems affect China's ability to achieve the government's stated goals of a 'harmonious society' with 'moderate prosperity for all,' but these problems, and the ways that ...

    In order to study the carbon cycling in China deeply, a forest above ground biomass (AGB) estimation research is carried out under the support of 'Strategic Priority Research Program - Climate Change: Carbone Budget and Related Issues' of the Chinese Academy of Sciences (Carbon Project). The research aims to estimate the forest AGB in 2000, 2005 and 2010 in China, and analyzes its dynamic changes. The overall thinking of the research is using field works and airborne LiDAR data as basis to estimate the AGB in GLAS footprints, and then extrapolating discrete AGB to continuous results with optical and auxiliary data. Due to the large area of China, totally 8 sub-areas are marked out based on the different forest ecosystems and some other factors (Table 1 and Fig. 1). Here, a latest China's land cover product (the background of Fig 1), named 'ChinaCover', and also supported by the 'Carbon Project', is imported to classify the forest types. There are around 5000 sample plots (Table 1) surveyed by the 'Carbon Project'. It can provide a large number of training and validation data. At the same time, the research sets 6 other typical sample areas, which have areas of 60 to 200 km2, and airborne LiDAR flights are carried out to obtain high accuracy AGB in these areas. With the sample plots and 6 typical sample areas, the AGB in GLAS footprint is estimated. Since the sample plots and LiDAR flights were carried out in 2012, the height and area parameters extracted from GLAS footprint are corrected by tree growth model of different forest types. In a further step, extrapolation models are built together with time-series MODIS and auxiliary data. These models fully consider the time-series features and propose several long time-series indices to minimize the influence of spectral saturation. Results are validated by samples and compared to the result of some other researches. At last, the models are applied to the data of 2000, 2005 and 2010 to get the corresponding AGB maps

    International Nuclear Information System (INIS)

    In this report some validation tests for the TESEO code are described. The TESEO code was developed at ENEA - Clementel Center in the framework of the C2RV code sequence. This code sequence produces multigroup resonance cross sections for fast reactor analysis. It consists of the codes TESEO, MC2-II, GERES, ANISN, MEDIL. The TESEO code processes basic nuclear data in ENDF-B format and produces an ultrafine group (2082 groups) cross section library for the MC2-II code. To validate the TESEO algorithms, the data produced by TESEO code were compared with the data produced by other well-tested codes which use different algorithms. No substantial differences was found between these data and the data produced by TESEO code. TESEO algorithms showed high reliability. A detailed study of TESEO calculation options was carried out. Their use and functions are shown to inform the user of the code

    Since the end of the Cold War, China's military diplomacy has displayed an omni-directional and multi-level form, and with an increasing transparency which has increased trust and reduced doubt. China has enhanced its conventional military functions and strengthened its military soft power. This has helped China develop into a responsible state on the world stage. Through military exchanges with other countries, the Chinese military has gradually strengthened its ability to undertake a variety of tasks. The Chinese military has to make greater efforts to counter the perception of a "China threat." There is also a need to establish a system of military spokesmen and to develop a theory of military diplomacy with Chinese characteristics.

    Full Text Available Orphan care in China was once provided by the central government as a means of social control. The centralized welfare delivery guaranteed some of the poorest orphans to be protected by the government. Since the economic reform, the central government started to relinquish its control over social welfare delivery, new forms of orphan care were introduced into China, sharing the responsibilities and burdens for caring the orphans. Yet, many issues and problems exist in social delivery due to a lack of finances, professionals, and policy support. In this chapter, we will discuss the background of social welfare changes in China, as pertains to orphan care, focusing on the different types of orphans as a result of social issues, service delivery, barriers and solutions. It is claimed that during the reform, the burden of orphan care in China may not be reduced in the coming future, and we offer suggestions to cope with that.

Twenty years later, the number of HIV/AIDS patients has risen alarmingly. In 2003, the Chinese Ministry of Health launched an AIDS Epidemiological Investigation across China with the support of the WHO and UN AIDS Program. Its results show that there are currently 840,000 HIV carriers, including 80,000 people with full-blown AIDS, in 31 Chinese provinces, municipalities and autonomous regions. This means China has the second highest number of HIV/AIDS cases in Asia and 14th highest in the world.

    Vegetation indices (Ⅵ) are one of the standard science products available from the Moderate Resolution Imaging Spectroradiometer (MODIS). Validation of MODIS-Ⅵ products was an important prerequisite to using these variables for global modeling. In this study, validation of the MODIS-VI products including single-day MODIS, level 2 (gridded) daily MODIS surface reflectance (MOD09), 16-day composited MODIS (MOD13) was performed utilizing multisensor data from MODIS, Thematic Mapper (TM), and field radiometer, for a rice-planting region in southern China. The validation approach involved scaling up independent fine-grained datasets, including ground measurement and high spatial resolution imagery, to the coarser MODIS spatial resolutions. The 16-day composited MODIS reflectance and Ⅵ matched well with the ground measurement reflectance and Ⅵ. The Ⅵ of TM and MODIS were lower than the ground Ⅵ. The results demonstrated the accuracy, reliability, and utility of the MODIS-Ⅵ products for the study region.

    The Energy Analysis Program (EAP) at the Lawrence Berkeley Laboratory (LBL) first became involved in Chinese energy issues through a joint China-US symposium on markets and demand for energy held in Nanjing in November of 1988. Discovering common interests, EAP began to collaborate on projects with the Energy Research Institute (ERI) of China`s State Planning Commission.

Preparing this volume confronted us with a number of difficult issues. The most frustrating usually involved the different approaches to sectoral divisions taken in China and the US. For instance, fuel used by motor vehicles belonging to industrial enterprises is counted as industrial consumption in China; only fuel use by vehicles belonging to enterprises engaged primarily in transportation is countcd as transportation use. The estimated adjustment to count all fuel use by vehicles as transportation energy use is quite large, since a large fraction of motor vehicles belong to industrial enterprises. Similarly, Chinese industrial investment figures are skewed compared to those collected in the US because a large portion of enterprises` investment funds is directed towards providing housing and social services for workers and their families.

It also suggests that the development of China's geoculture should be based on a triple-circled geopolitical pattern, and should adopt a strategy of addressing regional issues first and global issues second. China's priorities should be the building up of its own culture, the consolidation of neighboring geocultural space, promoting the geocultural integration of Asia, becoming more involved in global geocultural interactions, and enhancing China's cultural influence and status.

    The South China Sea is poorly understood in terms of its marine biota, ecology and the human impacts upon it. What is known is most often contained in reports and workshops and conference documents that are not available to the wider scientific community. The South China Sea has an area of some 3.3 million km{sup 2} and depths range from the shallowest coastal fringe to 5377m in the Manila Trench. It is also studded with numerous islets, atolls and reefs many of which are just awash at low tide. It is largely confined within the Tropic of Cancer and, therefore, experiences a monsoonal climate being influenced by the Southwest Monsoon in summer and the Northeast Monsoon in winter. The South China Sea is a marginal sea and, therefore, largely surrounded by land. Countries that have a major influence on and claims to the sea include China, Malaysia, the Philippines and Vietnam, although Thailand, Indonesia and Taiwan have some too. The coastal fringes of the South China Sea are home to about 270 million people that have had some of the fastest developing and most vibrant economics on the globe. Consequently, anthropogenic impacts, such as over-exploitation of resources and pollution, are anticipated to be huge although, in reality, relatively little is known about them. The Indo-West Pacific biogeographic province, at the centre of which the South China Sea lies, is probably the world's most diverse shallow-water marine area. Of three major nearshore habitat types, i.e., coral reefs, mangroves and seagrasses, 45 mangrove species out of a global total of 51, most of the currently recognised 70 coral genera and 20 of 50 known seagrass species have been recorded from the South China Sea. The island groups of the South China Sea are all disputed and sovereignty is claimed over them by a number of countries. Conflicts have in recent decades arisen over them because of perceived national rights. It is perhaps because of this that so little research has been undertaken

    2016-08-01

    The Dyadic Coping Inventory (DCI, Bodenmann, 2008) assesses how couples support each other when facing individual (e.g., workload) and common (e.g., parenting) stressors. Specifically, the DCI measures partners' perceptions of their own (Self) and their partners' behaviors (Partner) when facing individual stressors, and partners' common coping behaviors when facing common stressors (Common). To date, the DCI has been validated in 6 different languages from individualistic Western cultures; however, because culture can affect interpersonal interactions, it is unknown whether the DCI is a reliable measure of coping behaviors for couples living in collectivistic Eastern cultures. Based on data from 474 Chinese couples (N = 948 individuals), the current study examined the Chinese version of the DCI's factorial structure, measurement invariance (MI), and construct validity of test scores. Using 3 cultural groups (China, Switzerland, and the United States [U.S.]), confirmatory factor analysis revealed a 5-factor structure regarding Self and Partner and a 2-factor structure regarding Common dyadic coping (DC). Results from analyses of MI indicated that the DCI subscales met the criteria for configural, metric, and full/partial scalar invariance across cultures (Chinese-Swiss and Chinese-U.S.) and genders (Chinese men and women). Results further revealed good construct validity of the DCI test scores. In all, the Chinese version of the DCI can be used for measuring Chinese couples' coping behaviors, and is available for cross-cultural studies examining DC behaviors between Western and Eastern cultures.

Sets of rules, ways to assess the consistency of rules and behavior within the organization are defined. Using ontologies are obtained qualifications that assess the organization's audit. Elaboration of the audit reports is a perfect algorithm-based activity characterized by generality, determinism, reproducibility, accuracy and a well-established. The auditors obtain effective levels. Through ontologies obtain the audit calculated level. Because the audit report is qualitative structure of information and knowledge it is very hard to analyze and interpret by different groups of users (shareholders, managers or stakeholders. Developing ontology for audit reports validation will be a useful instrument for both auditors and report users. In this paper we propose an instrument for validation of audit reports contain a lot of keywords that calculates indicators, a lot of indicators for each key word there is an indicator, qualitative levels; interpreter who builds a table of indicators, levels of actual and calculated levels.

    Over the past 50 years, with the improvement of relationship between India and China, the scope of India studies in China's IR research has been broadened and the new areas of studies are being explored. The research agenda of India studies has already extended to the areas like economy, society, culture, security, national strategy and their impact on both bilateral and international relations. In this situation, the focuses of India studies in China's IR research can be mainly identified as follows: reviews on India's social, political and economic systems; analysis on the national strategy and foreign policy; Sino-Indian relations; India's relations with some international organizations. However, even though many fresh progresses have been made in India studies, the India studies in China's IR research still lag far behind the study of other important countries like the U.S., UK, Russia and Japan, and more problems and challenges will face in the coming future. The paper believes that a fuller understanding of India probably will not make China and India close friends, but it definitely will help to prevent them from becoming fierce enemies.

    Palaeogeography is a science that studies the features and evolution of physical geography in geological history and human history. The palaeogeography of China has multiple disciplines and multiple types of palaeogeographic map. These perfectly reflect "a hundred flowers blossom and a hundred schools of thought content". The palaeogeography of China has three characteristics. The first is multiple disciplines flourishing simultaneously. The second is that lithofacies palaeogeography is in a leading position. The third is that palaeogeography of China is closely connected with industrial practice. It is why palaeogeography, especially lithofacies palaeogeography of China, can flourish continually. We have two journals of palaeogeography, i. e. Journal of Palaeogeography (Chinese Edition) and Journal of Palaeogeography (English Edition). The former primarily publishes articles of Chinese authors regarding Chinese palaeogeography and related disciplines and has a foothold in China. The latter will publish the articles of both Chinese and international authors and caters to foreign readers. These two journals will cooperate together and display their own expertise, which will effectively make a great contribution to the development and innovation of Chinese palaeogeography and international palaeogeography.

    China is a country with significant but unevenly distributed water resources. The water stressed North stays in contrast to the water abundant and polluted South defining China's current water environment. In this paper we use the latest available data sets and adopt structural decomposition analysis for the years 1992 to 2007 to investigate the driving forces behind the emerging water crisis in China. We employ four water indicators in China, that is, freshwater consumption, discharge of COD (chemical oxygen demand) in effluent water, cumulative COD and dilution water requirements for cumulative pollution, to investigate the driving forces behind the emerging crisis. The paper finds water intensity improvements can effectively offset annual freshwater consumption and COD discharge driven by per capita GDP growth, but that it had failed to eliminate cumulative pollution in water bodies. Between 1992 and 2007, 225 million tones of COD accumulated in Chinese water bodies, which would require 3.2-8.5 trillion m(3) freshwater, depending on the water quality of the recipient water bodies to dilute pollution to a minimum reusable standard. Cumulative water pollution is a key driver to pollution induced water scarcity across China. In addition, urban household consumption, export of goods and services, and infrastructure investment are the main factors contributing to accumulated water pollution since 2000. PMID:25226569

    Test data on canonical weapon-like fixtures are used to validate previously developed analytical bounding results. The test fixtures were constructed to simulate (but be slightly worse than) weapon ports of entry but have known geometries (and electrical points of contact). The exterior of the test fixtures exhibited exterior resonant enhancement of the incident fields at the ports of entry with magnitudes equal to those of weapon geometries. The interior consisted of loaded transmission lines adjusted to maximize received energy or voltage but incorporating practical weapon geometrical constraints. New analytical results are also presented for bounding the energies associated with multiple bolt joints and for bounding the exterior resonant enhancement of the exciting fields.

It will then provide more information on the 11 operating NPPs, the 11 reactors under the construction in China, and the plans for the future. The current plan for 2005-2020 is to reach 40 GWe for NP by 2020, but the Chinese government is modifying this plan to increase the nuclear power target to 70 GWe along with other 30 GWe under the construction. Is it dream or will be implemented in the future? The total drilling footage finished in last two years reached 950 000 meters (450 000 meters in 2007 and 500 000 in 2008) including the 700 000 meters focused on the sedimentary basins in the northern China.

    2014-12-01

    This paper focuses on the radiative transfer in stars where opacities seem to raise problems : β-Cephei and solar-type stars. We first concentrate on the iron bump (log T = 5.25), responsible for β-Cephei pulsations through the κ-mechanism. To discriminate between the different opacity calculations used to predict their oscillations, new well-qualified calculations are used and compared to OP calculations. In parallel with this theoretical work, an experiment has been conducted at LULI 2000 in 2011 on iron and nickel. We show that this extended study pushes for the revision of the tables in the conditions corresponding to the iron bump region, at least for nickel. We will then deal with the Sun case for which we are preparing an opacity experiment on a high-energy laser, in some conditions of the radiative zone (T = [2 - 15 ×10^{6} K] and ρ = [0.2 - 150 g/cm^{3}]). To reach these high temperatures and densities at LTE and validate or not plasma effects and line widths, we are exploring an approach called the Double Ablation Front, driven by plasma radiative effects. The 1D simulations performed with the code CHIC show that with this technique, we could reach conditions equivalent to the conditions of half of the solar radiative zone.

  17. Spare Items validation

    International Nuclear Information System (INIS)

    There is an increasing difficulty for purchasing safety related spare items, with certifications by manufacturers for maintaining the original qualifications of the equipment of destination. The main reasons are, on the top of the logical evolution of technology, applied to the new manufactured components, the quitting of nuclear specific production lines and the evolution of manufacturers quality systems, originally based on nuclear codes and standards, to conventional industry standards. To face this problem, for many years different Dedication processes have been implemented to verify whether a commercial grade element is acceptable to be used in safety related applications. In the same way, due to our particular position regarding the spare part supplies, mainly from markets others than the american, C.N. Trillo has developed a methodology called Spare Items Validation. This methodology, which is originally based on dedication processes, is not a single process but a group of coordinated processes involving engineering, quality and management activities. These are to be performed on the spare item itself, its design control, its fabrication and its supply for allowing its use in destinations with specific requirements. The scope of application is not only focussed on safety related items, but also to complex design, high cost or plant reliability related components. The implementation in C.N. Trillo has been mainly curried out by merging, modifying and making the most of processes and activities which were already being performed in the company. (Author)

It is important to ensure that the data being sent is valid as it may contain entry errors, which may be consumed by different systems causing further errors. XML has become the defacto standard for data transfer. The XML Schema Definition language (XSD was created to help XML structural validation and provide a schema for data type restrictions, however it does not allow for more complex situations. In this article we introduce a way to provide rule based XML validation and correction through the extension and improvement of our SRML metalanguage.

  19. Why is China going nuclear?

    International Nuclear Information System (INIS)

    In November 2007, China's State Council approved its 'Medium- and Long-Term Nuclear Power Development Plan', which set as a goal to increase the nation's nuclear capacity from about 7 to 40 GWe by 2020. In March 2008, the National Development and Reform Commission suggested installed nuclear power capacity might even exceed 60 GWe by 2020 due to faster than expected construction. Even with this growth, nuclear power's share of China's installed total capacity would be only about 5 percent. Yet China's rapid nuclear expansion poses serious financial, political, security, and environmental challenges. This study investigates China's claim that nuclear energy is necessary to meet its growing energy demands by analyzing China's energy alternatives and assessing their likelihood of contributing to total Chinese capacity. By looking at China's transformative energy policy from several perspectives, this study finds that nuclear energy is indeed a necessity for China.

    Three uranium provinces are recognized in China, the Southeast China uranium province, the Northeast China-lnner Mongolia uranium province and the Northwest China (Xinjiang) uranium province. The latter two promise good potential for uranium resources and are major exploration target areas in recent years. There are two major types of uranium deposits: the Phanerozoic hydrothermal type (vein type) and the Meso-Cenozoic sandstone type in different proportions in the three uranium provinces. The most important reason or prerequisite for the formation of these uranium provinces is that Precambrian uranium-enriched old basement or its broken parts (median massifs) exists or once existed in these regions, and underwent strong tectonomagmatic activation during Phanerozoic time. Uranium was mobilized from the old basement and migrated upwards to the upper structural level together with the acidic magma originating from anatexis and the primary fluids, which were then mixed with meteoric water and resulted in the formation of Phanerozoic hydrothermal uranium deposits under extensional tectonic environments. Erosion of uraniferous rocks and pre-existing uranium deposits during the Meso-Cenozoic brought about the removal of uranium into young sedimentary basins. When those basins were uplifted and slightly deformed by later tectonic activity, roll-type uranium deposits were formed as a result of redox in permeable sandstone strata.

    The work of radiation protection has been given great attention in China. The Ministry of Health is the competent authority in charge of the work. Before the accident at Chernobyl, the government had formulated and promulgated laws and regulations concerning the radiation protection, such as the Basic Standard for Radiation Protection, the Basic Standard for Radiation Protection of Nuclear Plants, the institutions and organizations for monitoring radioactive pollution at national level and provincial level had been set up. After the accident at Chernobyl, each of the monitoring institutions and organizations took samples of air, subsided substances of atmosphere, rainwater, terrestrial surface water from various sources, vegetables, milk and thyroid glands of sheep and goats immediately, for the detection of radiation contamination. As far as we know that the samples had small extent contamination, the extent of contamination of samples in the south of China is smaller than that of samples in the north of China, that the content of nuclides in various samples is lower than the limits of radioactive substances set in national standard, and that radiation dosage subjected by residents of China caused by the contamination is also lower than the set quota in the national standard. The contamination did not interfere with the regular life of the residents

    The response to the first edition of the China Energy Databook was overwhelmingly positive, and has encouraged us to issue this revised, updated, and expanded edition. It has been a natural counterpart to the Energy Analysis Program`s continuing program of collaborative research with the Energy Research Institute. No other current reference volume dedicated to China`s energy system contains a similar variety and quality of material. We have revised some of the categories and data that appeared in the old volume. The adjustment for energy consumption in the transportation sector, for instance, has been slightly changed to include some fuel use in the commercial sector, which was previously left out. As another example, natural gas consumption statistics in the first edition greatly overstated electric utility use; we have rectified that error. Some tables have changed as statistical collection and reporting practices change in China. Figures on gross output value by sector stop with 1992, and economic output in subsequent years is covered by various measures of value-added, such as national income and gross domestic product.

  15. Nonrenewable energy cost of corn-ethanol in China

    International Nuclear Information System (INIS)

    Nonrenewable energy cost is accounted for the believed renewable biofuel of corn-ethanol in China. By a process-based energy analysis, nonrenewable energy cost in the corn-ethanol production process incorporating agricultural crop production, industrial conversion and wastewater treatment is conservatively estimated as 1.70 times that of the ethanol energy produced, corresponding to a negative energy return in contrast to the positive ones previously reported. Nonrenewable energy cost associated with wastewater treatment usually ignored in previous researches is shown important in the energy balance. Denoting the heavy nonrenewability of the produced corn-ethanol, the calculated nonrenewable energy cost would rise to 3.64 folds when part of the nonrenewable energy cost associated with water consumption, transportation and environmental remediation is included. Due to the coal dominated nonrenewable energy structure in China, corn-ethanol processes in China are mostly a conversion of coal to ethanol. Validations and discussions are also presented to reveal policy implications against corn based ethanol as an alternative energy in long term energy security planning. - Highlights: ► Nonrenewable energy (NE) cost is conservatively accounted for corn-ethanol in China. ► Corn cultivation, ethanol conversion and wastewater treatment are included. ► NE cost is estimated as 1.70 times that of the ethanol energy produced. ► Corn-ethanol processes in China are mostly a conversion of coal to ethanol.

    Cancer remains to be the second most common cause of death, and its incidence and mortality rates are increasing in China. According to the 2015 National Central Cancer Registry (NCCR) of China, the incidence of bladder cancer and prostate cancer ranked sixth and seventh, respectively, in male cancers. The majority of prostate cancer patients were diagnosed at an advanced stage. Early diagnosis of prostate cancer is the key to improve prostate cancer survival in China. Radical prostatectomy or radical radiotherapy is the main treatment for localized prostate cancer, and a comprehensive therapy based on androgen deprivation therapy is the treatment for advanced disease. The most common histologic types of bladder cancer in China were urothelial carcinoma, followed by adenocarcinoma and squamous carcinoma. The majority of patients were diagnosed using white-light cystoscopy with biopsy. Fluorescence and narrow-band imaging cystoscopy had additional detection rates and are becoming more popular. Following Chinese guidelines, most non-muscle invasive bladder cancer patients were treated with diagnostic transurethral resection and more than half of the muscle invasive bladder cancer patients were treated with radical cystectomy. Due to the increased detection rate of kidney tumors by ultrasound in physical examination, the number of incidentally diagnosed renal cell carcinoma has increased. Localized kidney cancers are more and more often treated by nephron-sparing surgery. Radical nephrectomy is still the main treatment option for patients with locally advanced renal cell carcinoma. Both laparoscopic and robotic-assisted laparoscopic surgeries have been used in big medical centers. Both testicular cancer and penile cancer have lower incidence levels than that in Europe. As we have an enormous population base, the absolute patient number is big. The diagnosis and treatment follows the Chinese guidelines. In China, both medical professionals and public should concern

    International Nuclear Information System (INIS)

    The Energy Analysis Program at the Lawrence Berkeley Laboratory (LBL) first became involved in Chinese energy issues through a joint China-US symposium on markets and demand for energy held in Nanjing in November of 1988. Discovering common interests, EAP began to collaborate on projects with the Energy Research Institute of China's State Planning Commission. In the course of this work it became clear that a major issue in the furtherance of our research was the acquisition of reliable data. In addition to other, more focused activities-evaluating programs of energy conservation undertaken in China and the prospects for making Chinese industries more energy-efficient, preparing historical reviews of energy supply and demand in the People's Republic of China, sponsoring researchers from China to work with experts at LBL on such topics as energy efficiency standards for buildings, adaptation of US energy analysis software to Chinese conditions, and transportation issues, we decided to compile, assess, and organize Chinese energy data. We are hopeful that this volume will not only help us in our work, but help build a broader community of Chinese energy policy studies within the US. In order to select appropriate data from what was available we established several criteria. Our primary interest was to use the data to help understand the historical evolution and likely future of the Chinese energy system. A primary criterion was thus that the data relate to the structure of energy supply and demand in the past and indicate probable developments (e.g., as indicated by patterns of investment). Other standards were accuracy, consistency with other information, and completeness of coverage. This is not to say that all the data presented herein are accurate, consistent, and complete, but where discrepancies and omissions do occur we have tried to note them

Most assessments of functional ability include Physical ADL (PADL) and Instrumental ADL....... The measure of Instrumental ADL included 30 activities in relation to tiredness and reduced speed. Construct validity was tested by the Rasch model for item analysis; internal validity was specifically addressed by assessing the homogeneity of items under different conditions. The Rasch item analysis...... of IADL showed that 14 items could be combined into two qualitatively different additive scales. The IADL-measure complies with demands for content validity, distinguishes between what the elderly actually do, and what they are capable of doing, and is a good discriminator among the group of elderly...

  5. Experimental validation of UTDefect

    International Nuclear Information System (INIS)

    This study reports on conducted experiments and computer simulations of ultrasonic nondestructive testing (NDT). Experiments and simulations are compared with the purpose of validating the simulation program UTDefect. UTDefect simulates ultrasonic NDT of cracks and some other defects in isotropic and homogeneous materials. Simulations for the detection of surface breaking cracks are compared with experiments in pulse-echo mode on surface breaking cracks in carbon steel plates. The echo dynamics are plotted and compared with the simulations. The experiments are performed on a plate with thickness 36 mm and the crack depths are 7.2 mm and 18 mm. L- and T-probes with frequency 1, 2 and 4 MHz and angels 45, 60 and 70 deg are used. In most cases the probe and the crack is on opposite sides of the plate, but in some cases they are on the same side. Several cracks are scanned from two directions. In total 53 experiments are reported for 33 different combinations. Generally the simulations agree well with the experiments and UTDefect is shown to be able to, within certain limits, perform simulations that are close to experiments. It may be concluded that: For corner echoes the eight 45 deg cases and the eight 60 deg cases show good agreement between experiments and UTDefect, especially for the 7.2 mm crack. The amplitudes differ more for some cases where the defect is close to the probe and for the corner of the 18 mm crack. For the two 70 deg cases there are too few experimental values to compare the curve shapes, but the amplitudes do not differ too much. The tip diffraction echoes also agree well in general. For some cases, where the defect is close to the probe, the amplitudes differ more than 10-15 dB, but for all but two cases the difference in amplitude is less than 7 dB. 6 refs

    Since China adopted an open door policy in 1978, its economy has grown rapidly. Between 1980 and 1993, China`s real GNP growth averaged 9.4 percent per year. Economists at the Chinese Academy of Social Sciences forecast that GNP will increase by 11.5 percent in 1994. During the rest of the decade, the Chinese government plans to reduce its annual GNP growth rate to 8-9 percent. During the 2001-2010 period, the economic growth rate is projected to decline to 6.5 percent per year. Table 1 compares China`s economic growth to other Asia-Pacific Economies, and includes projections to 2010. During the 1980s, China`s GDP growth rate was only second to that of South Korea. In the 1990`s, China is projected to have the highest economic growth in the Asia-Pacific region. China`s rapid economic growth is due to dramatic increases in the effective labor supply and effective capital stock. For the remainder of the 1990s, the effective labor supply should continue to increase rapidly because: (1) Chinese state enterprises are over-staffed and labor system reforms will move millions of these workers into more productive activities; (2) reforms in the wage system will provide increased incentives to work harder; (3) relaxation of migration controls from rural to urban areas will cause nominal labor in the industrial sector to accelerate; (4) differentials in personal income will increase and develop peer pressure on workers to work harder and earn more money; and (5) at China`s low personal income level, Chinese people are willing to trade leisure for more income as wages increase.

    Full Text Available Rather than China versus Islam, the overarching theme of this special issue is “Islam in China/China in Islam.” In thinking through “Islam in China,” we argue that the relationship between China and Islam is not one of opposition, but rather one of cultural, linguistic, and economic imbrication. Indeed, it is difficult to describe Islam and China as two separate or essentialized entities. For some Muslim minorities in certain regions of China, there is no distinction between neo-Confucianism and Islam or between the nation-state and the global umma (community of Muslims. Through intellectual labor, modes of prayer and worship, art, calligraphy, architecture, cuisine, linguistic creoles, and legal pluralism, these Muslims embody multiple cultural referents. For other Muslim minorities in other regions in China, political and economic circumstances present challenges to living in accordance with Islam while also being a citizen of the PRC. In other words, the Muslim experience in China encompasses a complex mosaic of accommodation, adjustment, preservation, and, at times, resistance. Thus, generalizations about this incredibly diverse population are unhelpful, and careful attention must be paid to history, politics, and place...

There are over 300,000 hectare of plantations in southern China, the main species planted since 1950 being Eucalyptus citriodora, E. exserta, and E. globulus. They provide a wide range of products including sawn timber, posts, poles, fuelwood and essential oils, and are a potential source of pulp and fibreboard. A recent policy decision to increase forest cover from 12.7 to 20% of the land area by 2000 will require an increase in afforestation rate to 2 million hectares/year: it is anticipated that eucalypts will play a significant role.

    The family planning program in China is integrated into the general political situation and the overall development program. The organization covers workers, peasants, and soldiers. The program is based on the following 3 aspects of Chinese society: 1) the equality of women, 3) late marriage, and 3) free and accessible contraceptive services. No incentives are offered since family planning is considered a national duty. Participation is said to be voluntary but peer opinion exerts its own social pressure. All contraceptive devices used in China are domestically produced. Barefoot doctors have a large role in their distribution. Examples from several localities indicate that the acceptance rate for contraception is high. An official with the Health Ministry is quoted regarding the family planning program. PMID:12277575

    International responsibility falls upon the shoulders of every country. China's growing contributions to world peace and development have surpassed the view of her as a "threat. "Instead, it was, among world mainstream opinion, expected to shoulder a still-bigger burden. Such external expectations, together with internal yearnings for a higher profile abroad, urge a response in terms of Chinese diplomacy. What is to be done? This paper explores the answer.

    Over the last decade, China has focused its policies simultaneously on moderating the rapid energy demand growth that has been driven by three decades of rapid economic growth and industrialization and on increasing its energy supply. In spite of these concerted efforts, however, China continues to face growing energy supply challenges, particularly with accelerating demand for oil and natural gas, both of which are now heavily dependent on imports. On the supply side, the recent 11th and 12th Five-Year Plans have emphasized accelerating conventional and nonconventional oil and gas exploration and development through pricing reforms, pipeline infrastructure expansions and 2015 production targets for shale gas and coal seam methane. This study will analyze China’s new and nonconventional oil and gas resources base, possible development paths and outlook, and the potential role for these nonconventional resources in meeting oil and gas demand. The nonconventional resources currently being considered by China and included in this study include: shale gas, coal seam methane (coal mine methane and coal bed methane), tight gas, in-situ coal gasification, tight oil and oil shale, and gas hydrates.

So far, over 120 important biologically active materials have been measured by radioimmunoassay in China, and 44 types of RIA kit have been supplied commercially. More than 50,000 cases of hyperthyroidism have been treated satisfactorily with 131I. Radionuclide imaging of practically all organs and systems of the human body has been performed, and adrenal imaging and nuclear cardiology have become routine clinical practice in several large hospitals. The thyroid iodine uptake test, renogram tracing and cardiac function studies with a cardiac probe are also commonly used in most Chinese hospitals. The active principles of more than 60 medicinal herbs have been labelled with isotopes in order to study the drug metabolism and mechanism of action. Through the use of labelled neurotransmitters or deoxyglucose, RIA, radioreceptor assay and autoradiography, Chinese researchers have made remarkable achievements in the study of the scientific basis of acupuncture analgesia. In 1980 the Chinese Society of Nuclear Medicine was founded, and since 1981 the Chinese Journal of Nuclear Medicine has been published. Although nuclear medicine in China has already made some progress, when compared with advanced countries, much progress is still to be made. It is hoped that international scientific exchange will be strengthened in the future. (author)

    Background So far, in China, there has been no effective or easy procedure to define the control of asthma. This study assesses the validity of Asthma Control Test in Chinese patients.Methods Three questionnaires (Asthma Control Test, Asthma Control Questionnaire and the 30 second asthma test)were administered to 305 asthma patients from 10 teaching hospitals across China. Spirometry was also used. Asthma specialists rated the control of asthma according to patients' symptoms, medications and forced expiratory volume in first second. The patients were divided into noncontrolled group and controlled group according to the specialists' rating.Reliability, empirical validity and screening accuracy were conducted for Asthma Control Test scores. Screening accuracy was compared among 3 questionnaires. The patients' self rating and the specialists' rating were also compared.Results The internal consistency reliability of the 5-item Asthma Control Test was 0.854. The correlation coefficient between Asthma Control Test and the specialists' rating was 0.729, which was higher than other instruments. Asthma Control Test scores discriminated between groups of patients differing in the percent predicted forced expiratory volume in first second (F=26.06, P<0.0001), the specialists' rating of asthma control (F=88.24, P<0.0001) and the Asthma Control Questionnaire scores (F=250.57, P<0.0001). Asthma Control Test showed no significant difference with Asthma Control Questionnaire in the percent correctly classified, while the percent correctly classified by Asthma Control Test was much higher than 30 second asthma test. The patients' self rating was the same as assessment of the specialists (t=0.65, P=0.516).Conclusion The Asthma Control Test is an effective and practicable method for assessing asthma control in China.

    2010-12-01

    Full Text Available Data Clustering is a technique of finding similar characteristics among the data set which are always hidden in nature and grouping them into groups, called as clusters. Different clustering algorithms exhibit different results, since they are very sensitive to the characteristics of original data set especially noise and dimension. The quality of such clustering process determines the purity of cluster and hence it is very important to evaluate the results of the clustering algorithm. Due to this, Cluster validation activity had been a major and challenging task. The major factor which influences cluster validation is the internal cluster validity measure of choosing the optimal number of clusters. The main objective of this article is to present a detailed description of the mathematical working of few cluster validity indices and not all, to classify these indices and to explore the ideas for the future promotion of the work in the domain of cluster validation. In addition to this, a maximization objective function is defined assuming to provide a cluster validation activity.

    Genetically modified organisms (GMOs) entered the European food market in 1996. Current legislation demands the labeling of food products if they contain GMO, as assessed for each ingredient of the product. To create confidence in the testing methods and to complement enforcement requirements, there is an urgent need for internationally validated methods, which could serve as reference methods. To date, several methods have been submitted to validation trials at an international level; approaches now exist that can be used in different circumstances and for different food matrixes. Moreover, the requirement for the formal validation of methods is clearly accepted; several national and international bodies are active in organizing studies. Further validation studies, especially on the quantitative polymerase chain reaction methods, need to be performed to cover the rising demand for new extraction methods and other background matrixes, as well as for novel GMO constructs.

    XSL Transformations (XSLT) is a programming language for defining transformations among XML languages. The structure of these languages is formally described by schemas, for example using DTD or XML Schema, which allows individual documents to be validated. However, existing XSLT tools offer no...... static guarantees that, under the assumption that the input is valid relative to the input schema, the output of the transformation is valid relative to the output schema. We present a validation technique for XSLT based on the XML graph formalism introduced in the static analysis of JWIG Web services...... and XACT XML transformations. Being able to provide static guarantees, we can detect a large class of errors in an XSLT stylesheet at the time it is written instead of later when it has been deployed, and thereby provide benefits similar to those of static type checkers for modern programming...

    The purpose of this thesis is to investigate how China's gender imbalance could affect East Asian security with respect to China-Japan relations and China-Taiwan relations. The research result is ambiguous in that China's excess males may or may not force the Chinese government to adopt a more aggressive foreign policy stance with Japan and Taiwan. On the one hand, the Chinese government has been relatively calm in its dealings with Japan and Taiwan despite the rise of Chinese nationalism. Th...

    The progress of nuclear instruments and their applications in China`s industries have been greatly dependent on the development of social economy. In recent years, the economy in China demands an increasing application of industrial nuclear instruments. The reliability of system performance and its adaptability are prerequisites to ensure widespread application in industry. Through the efforts over 40 years, a sound foundation for the development of nuclear instruments and their application has formed in China with the establishment of a comprehensive nuclear industrial system and skilled technical teams. The international cooperation and technical exchange between China and other countries has provided more opportunities to absorb new concepts, new ideas and new technology for upgrading current products and shorten the gap with the developed countries.

  9. Validation: an overview of definitions

    International Nuclear Information System (INIS)

    The term validation is featured prominently in the literature on radioactive high-level waste disposal and is generally understood to be related to model testing using experiments. In a first class, validation is linked to the goal of predicting the physical world as faithfully as possible but is unattainable and unsuitable for setting goals for the safety analyses. In a second class, validation is associated to split-sampling or to blind-tests predictions. In the third class of definition, validation focuses on the quality of the decision-making process. Most prominent in the present review is the observed lack of use of the term validation in the field of low-level radioactive waste disposal. The continued informal use of the term validation in the field of high level wastes disposals can become cause for misperceptions and endless speculations. The paper proposes either abandoning the use of this term or agreeing to a definition which would be common to all. (J.S.). 29 refs

    经济发展与城市蔓延一直是学者研究的热点,其假说大都建立在发展与保护矛盾不断激化的基础之上,论文基于国内外城市发展轨迹的判断,提出新的研究假说:经济发展与城市蔓延存在Logistic曲线关系,并选择华东地区典型城市进行实证检验。结果表明:第一,国外(区域)经济发展由快速城市化、工业化初级阶段过渡到高级或后工业化阶段进程中,对城市蔓延扩张的依赖程度逐渐减弱;第二,中国1978—2003年间经济发展与城市蔓延增长具有周期性波动特征,2003年以后两者波动出现明显脱钩或分歧;第三,实证结果显示,上海、南京、无锡和徐州的第二三产业GDP在分别达到2.91×1011、1.02×1011、4.43×1010、9.42×1010元时,城市蔓延扩张出现拐点,验证了研究假说,其规模上限分别为8.99×104、6.01×104、2.20×104、3.43×104 hm2。研究结论能够为我国城市蔓延治理和公共政策调整提供科学依据和直接参考。%Economic development and urban sprawl have been the scholar' s research hot spot, and the hypothesis is mostly based on the contradiction of the development and protection. This paper, based on the development track of cities at home and abroad, puts forward the new research perspective judgment. There is the Logistic curve between economic development and urban sprawl, and then the authors select the typical cities in East China for empirical test. As the results show: First, economic growth' dependence on urban sprawl weakened gradually abroad from the rapid ur- banization, industrialization primary phase transiting to the senior or after the process of industriali- zation stage. Second, China's economic growth and urban sprawl has periodical fluctuating charac- teristics from 1978 to 2003, and there have been significant decoupling or different fluctuations since 2003. Third, the empirical results show that turning points would come in urban

    This paper provides an outline of Cretaceous stratigraphy and paleogeography in China, which is based on rich data obtained from recent researches. Cretaceous deposits are widespread in China. Most strata are of nonmarine origin and marine sediments occur only in Tibet, western Tarim Basin of Xinjiang, Taiwan and limited localities of eastern Heilongjiang. All deposits are rich in fossils and well-constrained biostratigraphically. The stratigraphic successions of different regions are illustrated, and general stratigraphic division and correlation have been introduced. The marine deposits are described in the Tibetan Tethys, Kashi-Hotan Region of Xinjiang, eastern Heilongjiang, western Yunnan and Taiwan; the nonmarine deposits are outlined from northeast China, southeast China, southern interior China, southwest China, the Shaanxi-Gansu-Ningxia region, and northwestern China intermontane basins. The sedimentary facies and paleogeography are diversified. In Tibet the basin evolution is largely related to the subduction and collision of the Indian Plate against the Eurasian Continent, and shows a tectonic evolution in the Cretaceous. Foraminifera are a dominant biota in the Tibet Tethys. Nonmarine sediments include variegated and red beds, coal- or salt-bearing horizons, and volcanic rocks. These deposits contain diverse and abundant continental faunas and floras, as well as important coal and oil resources. The Cretaceous stratigraphy and paleogeography in China have presented a foundation for geological studies.

    Through analysis the actual coal supply and demand in the US and China, the properties of the coal supply-demand market in both countries are investigated based on the energy supply-demand network. The validity of our model is verified by comparing numerical results with empirical results. The comparison of empirical results and the comparison of coal network model parameters between in the US and in China reveal the essence of the internal differences and similarities of coal supply and demand in these two countries. The third stage of China's coal network was close to that of the US in 1995, indicating that the evolutional situation of China's coal market begins to transit to an oligopolistic type. Finally, suggestions for China's coal supply-demand strategy are put forward. (interdisciplinary physics and related areas of science and technology)

    Full Text Available Abstract Background China has had no effective and systematic information system to provide guidance for strengthening PHC (Primary Health Care or account to citizens on progress. We report on the development of the China results-based Logic Model for Community Health Facilities and Stations (CHS and a set of relevant PHC indicators intended to measure CHS priorities. Methods We adapted the PHC Results Based Logic Model developed in Canada and current work conducted in the community health system in China to create the China CHS Logic Model framework. We used a staged approach by first constructing the framework and indicators and then validating their content through an interactive process involving policy analysis, critical review of relevant literature and multiple stakeholder consultation. Results The China CHS Logic Model includes inputs, activities, outputs and outcomes with a total of 287 detailed performance indicators. In these indicators, 31 indicators measure inputs, 64 measure activities, 105 measure outputs, and 87 measure immediate (n = 65, intermediate (n = 15, or final (n = 7 outcomes. Conclusion A Logic Model framework can be useful in planning, implementation, analysis and evaluation of PHC at a system and service level. The development and content validation of the China CHS Logic Model and subsequent indicators provides a means for stronger accountability and a clearer sense of overall direction and purpose needed to renew and strengthen the PHC system in China. Moreover, this work will be useful in moving towards developing a PHC information system and performance measurement across districts in urban China, and guiding the pursuit of quality in PHC.

  10. [Family planning in China].

    Family planning in People's Republic of China between 1956 to 1970 has been marked by rapid change and total interrelation with the political and social developments. Since 1949, the Communist government has taken several measures to protect the mother and child. The campaign for family planning was started in 1956 by public meetings, posters, lectures with films, and an extensive distribution of contraceptive means. However, in 1965 there were still 2 trends among women: 1, based on tradition, supported the idea that a large number of children was a source of honor, prosperity and security; the other taking hold among younger women was in favor of family planning. The rural population was the latest to start practicing family planning. In 1963 a movement of socialist education was launched together with the formation of mobile medical teams to inform and educate people all over the country and to make known the various forms available for family planning. The contraceptive methods used included: male and female sterilisation (vasectomy for men and tube ligation for women), IUD, and condom; abortion, legal for women who already had children or if it was necessary for the mother's health; and oral contraceptives, which were produced in China. Medical services were reorganized and teams of "bare-foot doctors" were sent all over China. They lectured on health measures and fertility regulation. Intellectuals were sent to live in villages and exchange their knowledge with that of the peasants and workers. The tendency has been to limit the number of children to 2 or 3. The young people are recommended to postpone their marriage, women till they are 25, men till later. Nationally produced contraceptive means are being experimented with such as herbs, or a new intrauterine plastic device called "flower". The regions with national minorities like Tibet, the Inner Mongolia and Sinkiang had been under underpopulated and therefore population growth has been encouraged mainly

    Purpose.To introduce the epidemical, pathological, and clinical characteristics as well as the diagnostic and therapeutical experiences of endomyocardial fibrosis(EMF) in China. Data sources.A CMBdisc search was done of the Chinese-language literature published from January 1983 through June 1997 about EMF and/or restrictive cardiomyopathy. A manual search was then done for other contributions, including abstracts, between January 1965 and June 1997.Results. Eighty-seven Chinese cases of EMF were collected in this paper. There were 49 men and 38 women, with a mean age of 28±13 years(range, 8 to 68 years). The distribution of the cases is mainly in the south of China. Combined right and left ventricular disease occurs in 48 percent of cases, with pure right ventricular involvement occurring in 42 percent and pure left ventricular involvement in the remaining 10 percent of patients who are examined postmortem. The diagnosis of EMF was confirmed in 21 cases at autopsy, and in 66 cases by echocardiography, angiocardiography, and/or endomyocardial biopsy which showed the characteristic changes. Clinically, right-sided disease is the commonest variety. Endocardiectomy and tricuspid(n=7) or mitral(n=1) valves replacement have been performed in 8 patients. There were 2 operative deaths. Six patients had a satisfactory recovery postoperatively and living well in the follow-up duration. Conclusion.EMF has been diagnosed clinically and confirmed at necropsy in a number of cases in the south of China. The etiology, incidence and epidemiology are still unknown. The pathological and clinical features are similar to those in tropical areas, but right ventricular involvement is the commonest type in our country.

    Multiple-choice questions have long been widely used inlarge-scale language proficiency tests in China. Nowadays withthe dramatic increase in the number of test takers, the validityof this type of test is of much concern to various parties. Drawing upon the psycholinguistic theories, the author ofthis article recommends exploring the hidden process the test-takers go through in order to examine its validity. Takingmultiple-choice reading comprehension as an example, theauthor investigates the strategies the test takers employ intackling multiple-choice questions, thereby gaining insights intothe validity of the test type discussed. Such inquiry into test validity not only helps test-developersin their own validation of items, but also helps languageteachers and students in developing a positive attitude towardstests.

  19. China: Ingestion study

    International Nuclear Information System (INIS)

    Diet samples in China were collected according to the sampling strategy devised for the 'First Total Diet Study in China' in 1990 by the Institute of Nutrition and Food Hygiene, Chinese Academy of Preventive Medicine. Based on geographic location, dietary habits and cooking style, the whole of China was divided into 4 regions and from each region one province was selected for the survey. In each of these provinces, 3 survey points (one town and two countryside) were identified, from where 30 families were randomly chosen. The diet composition and the consumption of various food items were recorded by means of weight record for three successive days. Some of these details are given in second total diet study, carried out in China in 1992 [48]. The total diet composition as well as the average daily consumption of each food for Chinese adults, engaged in light physical activity was calculated for each region. Based on the composition of diet and individual food materials, all foods and the products derived from them were classified into the following 13 types: (1) Grain; (2). Beans and nuts; (3) Yam; (4) Meat (including poultry); (5) Egg; (6) Aquatic foods; (7) Milk; (8) Vegetable; (9) Fruits and its salads, etc.; (10) Sugar; (11) Soft beverages and drinking water; (12) Alcoholic beverages; (13) Spices and cooking oil. These foods were collected in 1997 from nearby vegetable markets, subsidiary food stores and farmer markets within the three-survey points in each region. Various foods thus collected were treated and cooked according to the local dietary habit in assigned restaurants and kitchens. Cooked foods were then ground and mixed in the blender. In all, 48 individual food samples were obtained representing the four regions. Samples under frozen condition were shipped to the analytical laboratory for further processing and analysis. All possible precautions already stated in the sampling and quality control chapter were taken to avoid contamination of samples

    The Beijing Olympics has focused unprecedented world attention on China this year. Many people hail the Games as an occasion that showcases China's growing contribution to world development and harmony. But intent on politicizing this global event, a few modern Cassandras still cling to the flawed China Threat theory. In this paper, the author traces the origins of this fallacious theory. He sees it as a product of Western empiricism viewed through an historical and philosophical prism. He argues that the assertion of threat arises from a generalization of historical facts. The assertion links China's growing clout with declining Western dominance in international affairs. Starting with the myth that peace is possible only among democracies, the theory predicts the inevitability of conflict between the West and China, a country with an alleged expansionist tradition and under an authoritarian system.

  5. Quality data validation: Comprehensive approach to environmental data validation

    International Nuclear Information System (INIS)

    Environmental data validation consists of an assessment of three major areas: analytical method validation; field procedures and documentation review; evaluation of the level of achievement of data quality objectives based in part on PARCC parameters analysis and expected applications of data. A program utilizing matrix association of required levels of validation effort and analytical levels versus applications of this environmental data was developed in conjunction with DOE-ID guidance documents to implement actions under the Federal Facilities Agreement and Consent Order in effect at the Idaho National Engineering Laboratory. This was an effort to bring consistent quality to the INEL-wide Environmental Restoration Program and database in an efficient and cost-effective manner. This program, documenting all phases of the review process, is described here

    As a naturally part of information technology, Remote Sensing (RS) is strongly required to provide very precise and accurate information product to serve industry, academy and the public at this information economic era. To meet the needs of high quality RS product, building a fully functional and advanced calibration system, including measuring instruments, measuring approaches and target site become extremely important. Supported by MOST of China via national plan, great progress has been made to construct a comprehensive calibration and validation (Cal&Val) site, which integrates most functions of RS sensor aviation testing, EO satellite on-orbit caration and performance assessment and RS product validation at this site located in Baotou, 600km west of Beijing. The site is equipped with various artificial standard targets, including portable and permanent targets, which supports for long-term calibration and validation. A number of fine-designed ground measuring instruments and airborne standard sensors are developed for realizing high-accuracy stepwise validation, an approach in avoiding or reducing uncertainties caused from nonsynchronized measurement. As part of contribution to worldwide Cal&Val study coordinated by CEOS-WGCV, Baotou site is offering its support to Radiometric Calibration Network of Automated Instruments (RadCalNet), with an aim of providing demonstrated global standard automated radiometric calibration service in cooperation with ESA, NASA, CNES and NPL. Furthermore, several Cal&Val campaigns have been performed during the past years to calibrate and validate the spaceborne/airborne optical and SAR sensors, and the results of some typical demonstration are discussed in this study.

    Whether the People's Republic of China may develop to an economical super-government in future depends on the amount of power and resources of this land. The security of power supply is in an extremely prominent position in the Agenda of the Chinese government. Under this aspect the author of the contribution under consideration reports on the power policy of China. The main aspects of this contribution are: (a) Trends of power consumption, productions and imports of power; (b) Power political targets, measures and instruments of China; (c) Characteristics, national and international impacts of the power policy of China. Due to the economical activities of the chinese oil industry worldwide as well as due to the increasing dependence from imports of petroleum and natural oil, China becomes a global player. Thus, one may expect an intensification of Beijing's economical activities with an increased military component. Nevertheless, the power policy of China is an important factor in the global competition according to fossil resources. In order to understand the future behaviour of China's power policy, one may have to take notice of the strategies relating the power policy and relating to foreign affairs. Furthermore, trends and problematic areas concerning the securitization of the power supply in the national area have to be observed.

  9. Process validation for radiation processing

    International Nuclear Information System (INIS)

    Process validation concerns the establishment of the irradiation conditions that will lead to the desired changes of the irradiated product. Process validation therefore establishes the link between absorbed dose and the characteristics of the product, such as degree of crosslinking in a polyethylene tube, prolongation of shelf life of a food product, or degree of sterility of the medical device. Detailed international standards are written for the documentation of radiation sterilization, such as EN 552 and ISO 11137, and the steps of process validation that are described in these standards are discussed in this paper. They include material testing for the documentation of the correct functioning of the product, microbiological testing for selection of the minimum required dose and dose mapping for documentation of attainment of the required dose in all parts of the product. The process validation must be maintained by reviews and repeated measurements as necessary. This paper presents recommendations and guidance for the execution of these components of process validation. (author)

  10. Validating LES for Jet Aeroacoustics

    2011-01-01

    Engineers charged with making jet aircraft quieter have long dreamed of being able to see exactly how turbulent eddies produce sound and this dream is now coming true with the advent of large eddy simulation (LES). Two obvious challenges remain: validating the LES codes at the resolution required to see the fluid-acoustic coupling, and the interpretation of the massive datasets that result in having dreams come true. This paper primarily addresses the former, the use of advanced experimental techniques such as particle image velocimetry (PIV) and Raman and Rayleigh scattering, to validate the computer codes and procedures used to create LES solutions. It also addresses the latter problem in discussing what are relevant measures critical for aeroacoustics that should be used in validating LES codes. These new diagnostic techniques deliver measurements and flow statistics of increasing sophistication and capability, but what of their accuracy? And what are the measures to be used in validation? This paper argues that the issue of accuracy be addressed by cross-facility and cross-disciplinary examination of modern datasets along with increased reporting of internal quality checks in PIV analysis. Further, it is argued that the appropriate validation metrics for aeroacoustic applications are increasingly complicated statistics that have been shown in aeroacoustic theory to be critical to flow-generated sound.

  11. Independent validation of ultrasonic inspection

    International Nuclear Information System (INIS)

    As a part of its inspection strategy for the Sizewell-B PWR station, the Central Electricity Generating Board (in part now Nuclear Electric) decided that the ultrasonic inspection procedures for the incredibility of failure components would be subjected to independent confirmation of their adequacy. The incorporation of validation into a large-scale inspection strategy was unique at the time (1982), indeed remains so today. The CEGB's general philosophy is one of diversity, redundancy and validation. In order to carry out independent validation of the specific procedures and ultrasonic operators to be used during the manufacture and in-service inspection of the reactor pressure vessel and steam plant components, the Inspection Validation Centre (IVC) has operated as a contractor to Nuclear Electric with special arrangements in place to guarantee independence. The setting-up and early methods of operation of IVC are briefly reviewed, the most recent operational experience summarized and the technical significance of the validations to date discussed.

    Full Text Available National legislation has been recognized as a valid and effective tool for connectivity conservation worldwide. However, the existing policy and law in China is not sufficient to meet the increasing challenges of connectivity conservation. Only a few regulations focus on fundamental principles rather than any substantive result, these are related to issues including without consideration of connectivity conservation in land-use plans, ambiguity of responsibility and accountability of design entity and management authority, lack of corresponding design criteria and operating guidelines. China needs to strengthen and integrate connectivity conservation factors into legal frameworks, which relate to plan content, the rights and responsibilities of all parties, and the process of environmental impact statement preparation.

  17. The awakening of China

    International Nuclear Information System (INIS)

    China has made a spectacular entry onto the international energy scene. Excluding one or two minor points, all studies agree on three essential factors:- 1) Energy consumption will continue to rise sharply over the next two decades even in the event of outstandingly high gains in energy efficiency.- 2) Coal will remain the predominant energy source during this same period despite the government's stated wish to significantly increase the use of natural gas and renewable energy sources.- 3) The increase in oil consumption over the next two decades will account fir or almost 20 % of the global increase in consumption. Fears in China and around the world concerning the negative impacts upon the environment both at a local and global scale and the continued tension in the oil market are both justified. It is likely that, as in the past, the oil market will adjust itself in order to balance supply and demand, but probably at a slower pace due to anticipated structural changes. Solutions to solve the problems related to the environment are not easy, and will require dialogue (involving India, the other y Asian giant) in addition to international co-operation going far be and the development mechanism itself.

  18. General aviation in China

    Science.gov (United States)

    Hu, Xiaosi

    In the last four decades, China has accomplished economic reform successfully and grown to be a leading country in the world. As the "world factory", the country is able to manufacture a variety of industrial products from clothes and shoes to rockets and satellites. But the aviation industry has always been a weak spot and even the military relies on imported turbofan engines and jet fighters, not to mention the airlines. Recently China has launched programs such as ARJ21 and C919, and started reform to change the undeveloped situation of its aviation industry. As the foundation of the aviation industry, the development of general aviation is essential for the rise of commercial aviation. The primary goal of this study is to examine the general aviation industry and finds the issues that constrain the development of the industry in the system. The research method used in this thesis is the narrative research of qualitative approach since the policy instead of statistical data is analyzed. It appears that the main constraint for the general aviation industry is the government interference.

  19. Breastfeeding in China.

    Liu, D S; Wang, X

    1995-01-01

    In China, where breast feeding was almost universal 30-40 years ago, the prevalence of breast feeding has declined rapidly in urban and periurban areas because of 1) separation of the newborn and mother in the hospital, 2) mothers returning to work early and working far from home, 3) perceptions of too little milk, and 4) easy access to substitutes. Studies have revealed that breast-fed babies over 6 months old grow at a slightly lower rate than bottle-fed babies, suggesting that proper weaning foods should be provided after 6 months of age. Breast feeding is associated with lower infant morbidity (lower respiratory infection, gastrointestinal tract infection, eczema, and rickets). Despite their fears to the contrary, Chinese mothers produce an amount of breast milk in the range of that produced by women in Western countries and greater than that produced by women in other developing countries. Studies of the nutritional composition of the milk of Chinese mothers also found that it is adequate for the baby's needs. Research has indicated, however, that the foods offered to the baby during weaning satisfy only about 18% of their caloric needs. Thus, not only does breast feeding need promotion in China, weaning practices also require modification. PMID:7495141

  20. Autosuficiencia alimentaria en China

    Full Text Available La seguridad alimentaria ha sido componente esencial de las diferentes estrategias de desarrollo socioeconómico de la República Popular China durante casi 50 años. Pero lo que comenzó como autosuficiencia en granos en el espacio de la aldea rural, en el contexto de economía cerrada y de aislamiento casi total respecto del resto del mundo evolucionó hasta convertirse en un conjunto de políticas para la agricultura, tendientes a la preservación de la independencia nacional en el aprovisionamiento de alimentos básicos, ya con amplia apertura al exterior y cierto grado de aprovechamiento de las ventajas comparativas regionales. El reto para China es preservar la seguridad alimentaria sin recurrir a las políticas anteriores de autosuficiencia a ultranza, cuyos costos económicos y sociales han dejado rastros en términos de desigualdad creciente entre campo y ciudad.
