    Full Text Available Regional ecosystems have been greatly affected by the rapid expansion of urban areas. In order to explore the impact of land use change on net primary productivity (NPP in rapidly developing cities during the current urbanization process, we quantified land use change in Liaoning province between 2000 and 2010 using net primary productivity as an indicator of ecosystem productivity and health. The Carnegie–Ames–Stanford Approach model was used to estimate NPP by region and land use. We used a unit circle-based evaluation model to quantify local urbanization effects on NPP around eight representative cities. The dominant land use types were farmland, woodland and urban, with urban rapidly replacing farmland. Mean annual NPP and total NPP decreased faster from 2005 to 2010 than from 2000 to 2005, reflecting increasing urbanization rates. The eastern, primarily woodland part of Liaoning province had the greatest reduction in NPP, while the western part, which was primarily farmland and grassland, had the lowest reduction.

    Wetlands are impacted by economic and political initiatives, and their ecosystem services are attracting increasing public attention. It is crucial that management decisions for wetland ecosystem services quantify the economic value of the ecosystem services. In this paper, we aimed to estimate a monetary value for coastal wetland ecosystem services in Liaoning Province, China. We selected 433 observations from 85 previous coastal wetland economic evaluations (mostly in China) including detailed spatial and economic characteristics in each wetland, then used a meta-analysis scale transfer method to calculate the total value of coastal wetland ecosystem services in Liaoning Province. Our results demonstrated that, on average, the ecosystem services provided by seven different coastal wetland types were worth US40,648 per ha per year, and the total value was 28,990,439,041 in 2013. Shallow marine waters accounted for the largest proportion (83.97%). Variables with a significant positive effect on the ecosystem service values included GDP per capita, population density, distance from the wetland to the city center and the year of evaluation, while wetland size and latitude had negative relationships.

    This paper reports the successful entrepreneurial endeavors of members of a 20-person women's group in Liaoning Province, China. Jing Yuhong, a member of the Family Planning Association at Shileizi Village, Dalian City, provided the basis for their achievements by first building an entertainment/study room in her home to encourage married women to learn family planning. Once stocked with books, magazines, pamphlets, and other materials on family planning and agricultural technology, dozens of married women in the neighborhood flocked voluntarily to the room. Yuhong also set out to give these women a way to earn their own income as a means of helping then gain greater equality with their husbands and exert greater control over their personal reproductive and social lives. She gave a section of her farming land to the women's group, loaned approximately US$5200 to group members to help them generate income from small business initiatives, built a livestock shed in her garden for the group to raise marmots, and erected an awning behind her house under which mushrooms could be grown. The investment yielded $12,000 in the first year, allowing each woman to keep more than $520 in dividends. Members then soon began going to fairs in the capital and other places to learn about the outside world, and have successfully ventured out on their own to generate individual incomes. Ten out of twenty women engaged in these income-generating activities asked for and got the one-child certificate.

    Full Text Available Geological faults are highly developed in the eastern Liaoning Province in China, where Mesozoic granitic intrusions and Archean and Paleoproterozoic metamorphic rocks are widely distributed. Although the heat flow value in eastern Liaoning Province is generally low, the hot springs are very developed. It is obvious that the faults have significant control over the distribution of hot springs, and traditional methods of spatial data analysis such as WofE (weight of evidence usually do not take into account the direction of the distribution of geothermal resources in the geothermal forecast process, which seriously affects the accuracy of the prediction results. To overcome the deficiency of the traditional evidence weight method, wherein it does not take the direction of evidence factor into account, this study put forward a combination of the Fry and WofE methods, Fry-WofE, based on geological observation, gravity, remote sensing, and DEM (digital elevation model multivariate data. This study takes eastern Liaoning Province in China as an example, and the geothermal prospect was predicted respectively by the Fry-WofE and WofE methods from the statistical data on the spatial distribution of the exposed space of geothermal anomalies the surface. The result shows that the Fry-WofE method can achieve better prediction results when comparing the accuracy of these two methods. Based on the results of Fry-WofE prediction and water system extraction, 13 favorable geothermal prospect areas are delineated in eastern Liaoning Province. The Fry-WofE method is effective in study areas where the geothermal distribution area is obviously controlled by the fault. We provide not only a new method for solving the similar issue of geothermal exploration, but also a new insight into the distribution of geothermal resources in Liaoning Province.

    The forest vegetation carbon stock and carbon sequestration rate in Liaoning Province, Northeast China, were predicted by using Canadian carbon balance model (CBM-CFS3) combining with the forest resource data. The future spatio-temporal distribution and trends of vegetation carbon storage, carbon density and carbon sequestration rate were projected, based on the two scenarios, i. e. with or without afforestation. The result suggested that the total forest vegetation carbon storage and carbon density in Liaoning Province in 2005 were 133.94 Tg and 25.08 t x hm(-2), respectively. The vegetation carbon storage in Quercus was the biggest, while in Robinia pseudoacacia was the least. Both Larix olgensis and broad-leaved forests had higher vegetation carbon densities than others, and the vegetation carbon densities of Pinus tabuliformis, Quercus and Robinia pseudoacacia were close to each other. The spatial distribution of forest vegetation carbon density in Liaoning Province showed a decrease trend from east to west. In the eastern forest area, the future increase of vegetation carbon density would be smaller than those in the northern forest area, because most of the forests in the former part were matured or over matured, while most of the forests in the later part were young. Under the scenario of no afforestation, the future increment of total forest vegetation carbon stock in Liaoning Province would increase gradually, and the total carbon sequestration rate would decrease, while they would both increase significantly under the afforestation scenario. Therefore, afforestation plays an important role in increasing vegetation carbon storage, carbon density and carbon sequestration rate.

    Full Text Available This paper presents the results of snow cover monitoring studies in Liaoning Province, northeastern China, using MODIS data. Snow cover plays an important role in both the regional water balance and soil moisture properties during the early spring in northeastern China. In addition, heavy snowfalls commonly trigger hazards such as flooding, caused by rapid snow melt, or crop failure, resulting from fluctuations in soil temperature associated with changes in the snow cover. The latter is a function of both regional, or global, climatic changes, as well as fluctuations in the albedo resulting from variations in the Snow Covered Area (SCA. These impacts are crucial to human activities, especially to those living in middle-latitude areas such as Liaoning Province. Thus, SCA monitoring is currently an important tool in studies of global climate change, particularly because satellite remote sensing data provide timely and efficient snow cover information for large areas. In this study, MODIS L1B data, MODIS Daily Snow Products (MOD10A1 and MODIS 8-day Snow Products (MOD10A2 were used to monitor the SCA of Liaoning Province over the winter months of November–April, 2006–2008. The effects of cloud masking and forest masking on the snow monitoring results were also assessed. The results show that the SCA percentage derived from MODIS L1B data is relatively consistent, but slightly higher than that obtained from MODIS Snow Products. In situ data from 25 snow stations were used to assess the accuracy of snow cover monitoring from the SCA compared to the results from MODIS Snow Products. The studies found that the SCA results were more reliable than MODIS Snow Products in the study area.

    To understand the influence of floods on bacillary dysentery in Liaoning province. The monthly surveillance data of bacillary dysentery, floods, meteorological and demographic data in Liaoning from 2004 to 2010 were collected. Panel Poisson regression analysis was conducted to evaluate the influence of floods on the incidence of bacillary dysentery in Liaoning. The mean monthly morbidity of bacillary dysentery was 2.17 per 100 000 during the study period, the bacillary dysentery cases mainly occurred in during July-September. Spearman correlation analysis showed that no lagged effect was detected in the influence of floods on the incidence of bacillary dysentery. After adjusting the influence of meteorological factors, panel data analysis showed that the influence of floods on the incidence of bacillary dysentery existed and the incidence rate ratio was 1.439 4(95%CI: 1.408 1-1.471 4). Floods could significantly increase the risk of bacillary dysentery for population in Liaoning.

    The present study was performed to investigate the seroprevalence and risk factors for Dirofilaria immitis infection in cats from Liaoning province, northeastern China. From October 2014 to September 2016, sera of 651 cats, including 364 domestic cats and 287 feral cats (332 females and 319 males) were assessed. They were tested for the presence of D. immitis antigen using SNAP Heartworm RT test kit. In this population, the average prevalence was 4.5%. Age and rearing conditions (feral or domestic) were found to be associated with the prevalence of D. immitis. The prevalence was significantly higher in feral cats compared with domestic cats (8.4% vs 1.4%, P0.05), but older cats (≥3 years old) showed a statistically higher prevalence compared with younger cats (cats (2.4% vs 0.51%, P>0.05), all these results suggest that outdoor exposure time may be one of the most important factors for D. immitis prevalence in cats. Results reveal that D. immitis are prevalence in domestic and feral cats in northeastern China, which indicates that appropriate preventive measures should be taken to decrease the incidence of feline heartworm disease in Liaoning province, northeastern China.

    The contradiction between energy consumption and economic growth is increasingly prominent in China. Liaoning Province as one of Chinese heavy industrial bases, consumes a large amount of energy. Its economic development has a strong dependence on energy consumption, but the energy in short supply become more apparent. In order to further understand the relationship between energy consumption and economic growth and put forward scientific suggestions on low carbon development, we used the grey correlation analysis method to separately examine the relevance of economic growth with energy consumption industries and energy consumption varieties through analy sis of energy consumption and economic growth data in Liaoning Province from 2000 to 2012. The results showed that the wholesale and retail sector and hotel and restaurant sector were in the minimum energy consumption in all kinds of sectors, but they presented the closest connection with the economic growth. Although industry energy consumption was the maximum, the degree of connection between industry energy consumption and economic growth was weak. In all types of energy consumption, oil and hydro-power consumption had a significant connection with economic growth. However, the degree of connection of coal consumption with economic growth was not significant, which meant that coal utilization efficiency was low. In order to achieve low carbon and sustainable development, Liaoning Province should transform the economic growth mode, adjust industry structure, optimize energy structure, and improve energy utilization efficiency, especially promote producer services and develop clean and renewable energy.

    Water and energy are important resources for regional economies and are inextricably and reciprocally linked. Global water and energy demand will increase significantly by 2030 while climate change will worsen water availability. Thus, it is important to ensure a sustainable energy supply despite the increasing severity of water resource constraints. Numerous studies have analyzed water requirements to produce energy from production perspectives. However, energy is generally supplied by both internal and external producers. Thus, it is necessary to consider the availability of water to produce energy from consumption perspectives also. We evaluate the water footprint of the energy supply of Liaoning Province, China. We apply the standard top-down approach using an input–output framework. We estimate the water footprint of the energy supply of Liaoning Province at 854 million m 3 in 2002, with 47% of water used for electricity and heating. Our results reveal that energy supply could depend on water resources in neighboring provinces; external producers met 80% of the water footprint of energy supply, although only 35% of energy supply was imported. If Liaoning Province decreased its external dependency, withdrawal of available water resources within the province would increase from 86% to 91%. To guarantee future regional energy security, it is important to manage water resources effectively through water-efficient electricity generation and by allocating water resources among sectors. - Highlights: • We assess the water footprint of energy supply (WFES) for Liaoning Province, China. • The WFES for 2002 was 854 million m 3 , with 47% used for electricity and heating. • External sources accounted for 80% of the WFES and 47% of the energy supply. • Without energy imports, water resource withdrawal would increase from 86% to 91%. • Effective water resource management is important for regional energy security

    This study characterized the genetic variations of mitochondrial DNA (mtDNA) to elucidate the maternal genetic structure of Liaoning Han Chinese. A total of 317 blood samples of unrelated individuals were collected for analysis in Liaoning Province. The mtDNA samples were analyzed using two distinct methods: sequencing of the hypervariable sequences I and II (HVSI and HVSII), and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis of the coding region. The results indicated a high gene diversity value (0.9997 ± 0.0003), a high polymorphism information content (0.99668) and a random match probability (0.00332). These samples were classified into 305 haplotypes, with 9 shared haplotypes. The most common haplogroup was D4 (12.93%). The principal component analysis map, the phylogenetic tree map, and the genetic distance matrix all indicated that the genetic distance of the Liaoning Han population from the Tibetan group was distant, whereas that from the Miao group was relatively close.

    Accurate estimates of forest carbon storage and changes in storage capacity are critical for scientific assessment of the effects of forest management on the role of forests as carbon sinks. Up to now, several studies reported forest biomass carbon (FBC) in Liaoning Province based on data from China's Continuous Forest Inventory, however, their accuracy were still not known. This study compared estimates of FBC in Liaoning Province derived from different methods. We found substantial variation in estimates of FBC storage for young and middle-age forests. For provincial forests with high proportions in these age classes, the continuous biomass expansion factor method (CBM) by forest type with age class is more accurate and therefore more appropriate for estimating forest biomass. Based on the above approach designed for this study, forests in Liaoning Province were found to be a carbon sink, with carbon stocks increasing from 63.0 TgC in 1980 to 120.9 TgC in 2010, reflecting an annual increase of 1.9 TgC. The average carbon density of forest biomass in the province has increased from 26.2 Mg ha−1 in 1980 to 31.0 Mg ha−1 in 2010. While the largest FBC occurred in middle-age forests, the average carbon density decreased in this age class during these three decades. The increase in forest carbon density resulted primarily from the increased area and carbon storage of mature forests. The relatively long age interval in each age class for slow-growing forest types increased the uncertainty of FBC estimates by CBM-forest type with age class, and further studies should devote more attention to the time span of age classes in establishing biomass expansion factors for use in CBM calculations.

    In order to uncover driving forces for provincial CO 2 emission in China, a case study was undertaken to shed light on the CO 2 emission growth in such a region. Liaoning province was selected due to its typical features as one industrial province. The environmental input–output analysis and structure decomposing analysis have been conducted in order to provide a holistic picture on Liaoning's CO 2 emissions during 1997–2007. Research outcomes indicate that rapid increase of per capita consumption activities is the main driver for Liaoning to have a significant CO 2 emission growth, followed by consumption structure, production structure and population size. Energy intensity and energy structure partly offset the CO 2 emission increase. Electricity power and heat supply and construction sectors caused the most CO 2 emission, indicating that more specific mitigation policies for these two sectors should be prepared. From final demand point of view, it is clear that trade plays a leading role in regional CO 2 emission, followed by fixed capital investment and urban household consumption which become increasingly important over time. Consequently, in order to realize low carbon development, local governments should consider all these factors so that appropriate mitigation policies can be raised by considering the local realities. - Highlights: • Driving forces for Liaoning's CO 2 emission have been uncovered through the use of IO-SDA model. • Construction and electricity power/heat supply sectors have the highest embodied emissions. • Trade plays a key role on regional CO 2 emission in Chinese old industrial base. • Fixed capital investment and urban households generated more CO 2 emissions

    Carbon emissions due to land use change have an important impact on global climate change. Adjustment of regional land use patterns has a great scientific significance to adaptation to a changing climate. Based on carbon emission/absorption parameters suitable for Liaoning Province, this paper estimated the carbon emission of land use change in the city and town concentrated area of central Liaoning Province. The results showed that the carbon emission and absorption were separately 308.51 Tg C and 11.64 Tg C from 1997 to 2010. It meant 3.8% of carbon emission. was offset by carbon absorption. Among the 296.87 Tg C net carbon emission of land use change, carbon emission of remaining land use type was 182.24 Tg C, accounting for 61.4% of the net carbon emission, while the carbon emission of land use transformation was 114.63 Tg C, occupying the rest 38.6% of net carbon emission. Through quantifying the mapping relationship between land use change and carbon emission, it was shown that during 1997-2004 the contributions of remaining construction land (40.9%) and cropland transform ation to construction land (40.6%) to carbon emission were larger, but the greater contributions to carbon absorption came from cropland transformation to forest land (38.6%) and remaining forest land (37.5%). During 2004-2010, the land use types for carbon emission and absorption were the same to the period of 1997-2004, but the contribution of remaining construction land to carbon emission increased to 80.6%, and the contribution of remaining forest land to carbon absorption increased to 71.7%. Based on the carbon emission intensity in different land use types, we put forward the low-carbon regulation countermeasures of land use in two aspects.

    To achieve sustainable development of the society, the People's Republic of China (PRC) proposed in its 11th Five-Year Plan for National Economic and Social Development Program a shift in energy-saving target of decreasing energy intensity by 20% in 2010 compared with that of 2005. Liaoning province is one of the oldest industrial bases in China. Policymakers are often confronted with problems relating to adjustment in the development pattern as a means to secure steady economic growth. The power industry is a fundamental energy industry; it plays an important role in realizing of energy-saving targets. Based on the input-output model, this paper sets extensive, planning and 20% energy-saving scenarios in order to analyze energy-saving and power consumption situations for Liaoning by 2010. Through extensive simulations, the levels of energy-saving and power demand under different scenarios are obtained. Results from the analysis show that under the premises of adjusting the ratio of investment and consumption, optimizing products structure, and improving energy use efficiency, it is possible to achieve the proposed energy-saving target. Liaoning's power consumption can maintain a stable growth trend in the future. The percentage of electricity to the total energy use can also increase to 16% in 2010. (author)

    We imaged the crust structure beneath Jilin Province and Liaoning Province in China with fundamental mode Rayleigh waves recorded by 60 broadband stations deployed in the region. Surface-wave empirical Green's functions were retrieved from cross-correlations of inter-station data and phase velocity dispersions were measured using a frequency-time analysis method. Dispersion measurements were then utilized to construct 2D phase velocity maps for periods between 5 and 35 s. Subsequently, the phase-dispersion curves extracted from each cell of the 2D phase velocity maps were inverted to determine the 3D shear wave velocity structures of the crust. The phase velocity maps at different periods reflected the average velocity structures corresponding to different depth ranges. The maps in short periods, in particular, were in excellent agreement with known geological features of the surface. In addition to imaging shear wave velocity structures of the volcanoes, we show that obvious low-velocity anomalies imaged in the Changbaishan-Tianchi Volcano, the Longgang-Jinlongdingzi Volcano, and the system of the Dunmi Fault crossing the Jingbohu Volcano, all of which may be due to geothermal anomalies.

    Based on the integrated model of emergy-ecological footprint approaches, the ecological security of Liaoning Province, a typical case for the old industrial area, was quantitatively evaluated from 2003 to 2012, followed by a scenario analysis on the development trend of the ecological secu-rity by employing the gray kinetic model. The results showed that, from 2003 to 2012, the value of emergy ecological-capacity per capita in Liaoning Province decreased from 3.13 hm 2 to 3.07 hm 2 , while the emergy-ecological footprint increased from 13.88 hm 2 to 21.96 hm 2 , which indicated that the ecological deficit existed in Liaoning Province and the situation was getting worse. The ecological pressure index increased from 4.43 to 7.16 during the studied period, and the alert level of ecological security changed from light to middle level. According to the development trend, the emergy ecological capacity per capita during 2013-2022 would correspondingly decrease from 3.04 hm 2 to 2.98 hm 2 , while the emergy ecological footprint would increase from 22.72 hm 2 to 35.87 hm 2 , the ecological pressure index would increase from 7.46 to 12.04, and the ecological deficit would keep increasing and the ecological security level would slide into slightly unsafe condition. The alert level of ecological security would turn to be middle or serious, suggesting the problems in ecological safety needed to be solved urgently.

    Pig breeding pollution has become one of the important sources of environmental pollution, and the circular economy has provided an effective way to alleviate the pollution of pig breeding. In this paper, the “Three-in-one” and “Four-in-one” mode of circular economy with methane as link were constructed, and taking Liaoning Province as the research area, the economic benefits of different pig breeding modes were compared and analyzed. The results show that: (1) The modes of circular economy use the pig manure waste as raw materials through the digesters, solar greenhouse to generate new resources, compared with the traditional farming methods, created considerable economic benefits and also alleviated the pressure of pollution, is an effective way to control the pollution of pig breeding. (2) The economic benefit of the “Four-in-one” mode in Liaoning was much higher than the “Three-in-one” mode. The economic benefits of biogas digesters were higher than the “Three-in-one” mode of 125 million yuan, while the solar greenhouse would introduce the planting industry into the recycling chain, with a net profit of about 38.64*108 yuan.

    The distribution and zoning of air temperature over Liaoning Province, China were examined using the calculated values of air temperature derived from satellite data (GMS data) as well as from altitude data. The results are summarized as follows. At 02:00 LST the correlation coefficients for the air temperatures calculated from altitude compared with the observed air temperatures were the same as those of the air temperatures derived from GMS data. At 14:00 LST, however, the correlation coefficients for air temperatures calculated from altitude were less than those of the air temperatures derived from GMS data. This fact verifies that the distribution of air temperature in the day-time is affected by other factors than altitude. The distribution of air temperature in a cell of approximately 5'(latitude) x 7.5'(longitude) over Liaoning Province, china was estimated by using the regression equations between surface temperature derived from GMS and the observed air temperature. The distribution of air temperature was classified into 5 types, and the types are obtained at 14:00 LST are seasonal ones but the types at 02:00 LST are not related to season. Also, the regional classification for the air temperature was examined using this distribution of air temperature. This regional classification for the air temperature was similar to the published zoning of the agricultural climate. It became clear that the characteristic distribution of air temperature in a cell unit can be obtained by satellite data. And it is possible to define the zoning of air temperature for a cell unit by the accumulated analyses of satellite data over an extended period

  10. Emergy Evaluation of the Urban Solid Waste Handling in Liaoning Province, China

    Full Text Available Waste management is a distinct practice aimed at reducing its effects on health and the environment and increasing energy and material recovery. The urban waste management industry has been slow to adopt new technologies, such as sanitary landfills and incineration, which enable better treatment results. The aim of a thorough ecological-economic evaluation of different treatment technologies is to extract the maximum practical benefits from investments and to ensure the minimum environmental impacts of wastes. This paper compares four garbage treatment systems, including sanitary landfills systems, fluidized bed incineration system, grate type incineration system and the current landfills system in Liaoning Province, China. By considering the economic and environmental impacts of waste treatment and disposal, impact of emissions, and contribution of wastes input, this paper constructed an emergy-based urban solid waste model for evaluating the sustainability of the holistic systems. The results in Liaoning indicate that the human health losses caused by the harmful air emissions are ranked in this order: fluidized bed incineration > grate type incineration > current landfills > sanitary landfills, while the ecosystem losses are ranked: grate type incineration > fluidized bed incineration > sanitary landfills > current landfills. The electricity yield ratios are ranked: grate type incineration > fluidized bed incineration > sanitary landfills > current landfills. Taken together this suggests that in considering the incineration option, decision makers must weigh the benefits of incineration against the significant operating costs, potential environmental impacts, and technical difficulties of operating. Emergy analysis of the urban solid treatment systems can provide a set of useful tools which can be used to compare the comprehensive performances of different waste treatment processes for decision-making and optimizing the whole process.

    Full Text Available To promote sustainable urbanization and combat the economic, environmental, energy and safety issues that go with rapid motorization, the Ministry of Transport in China has introduced the “Transit Metropolis” program with a substantive amount of funds devoted to the implementation of the program in local governments. This represents the largest ever central government-led effort addressing transit metropolis development in the world. How has the program been implemented locally? Have the selected demonstration cities followed the same principle or taken comparable measures to implement their version of the transit metropolis? What is their performance? These questions remain unknown in the current literature. This article answers the above questions through a literature review, interviews and comparative case studies in Shenyang and Dalian, two large cities in Liaoning Province. It shows that both cities have successfully achieved the target levels for building a transit metropolis. Similarities between the two cities can be found their absence of any policies on automobile restriction and the presence of enormous efforts in transit network expansion and optimization. Differences lie in the fact that Shenyang has been more conventional in developing the transit metropolis, while Dalian has been more innovative and flexible in policy implementation. When comparing our empirical findings with the experience of creating transit metropolis elsewhere in China and in foreign countries, we find that policies and regulations restricting car use and calming traffic are not necessary conditions for successful transit metropolises; however, the attractiveness of transit infrastructure, combined with aesthetic and well-decorated street network is essential for a modal shift for transit. We also find that the perception on the transit metropolis in China more emphasizes transit service improvement, while the concept in Western countries more focuses on

    The characteristics of boundary layer structure during a persistent regional haze event over the central Liaoning city cluster of Northeast China from 16 to 21 December 2016 were investigated based on the measurements of particulate matter (PM) concentration and the meteorological data within the atmospheric boundary layer (ABL). During the observational period, the maximum hourly mean PM2.5 and PM10 concentrations in Shenyang, Anshan, Fushun, and Benxi ranged from 276 to 355 μg m-3 and from 378 to 442 μg m-3, respectively, and the lowest hourly mean atmospheric visibility (VIS) in different cities ranged from 0.14 to 0.64 km. The central Liaoning city cluster was located in the front of a slowly moving high pressure and was mainly controlled by southerly winds. Wind speed (WS) within the ABL (pollutants. A potential temperature inversion layer existed throughout the entire ABL during the earlier hazy episode [from 0500 Local Time (LT) 18 December to 1100 LT 19 December], and then a potential temperature inversion layer developed with the bottom gradually decreased from 900 m to 300 m. Such a stable atmospheric stratification further weakened pollutant dispersion. The atmospheric boundary layer height (ABLH) estimated based on potential temperature profiles was mostly lower than 400 m and varied oppositely with PM2.5 in Shenyang. In summary, weak winds due to calm synoptic conditions, strong thermal inversion layer, and shallow atmospheric boundary layer contributed to the formation and development of this haze event. The backward trajectory analysis revealed the sources of air masses and explained the different characteristics of the haze episodes in the four cities.

    Regional geologic characteristics, metallogenetic conditions and prospects of uranium ores in the central part of the Eastern Liaoning Province of North China is studied systematically. It demonstrates that the Archaean basement of the study area consists of a special type of granite-greenstone belts in China. It is called the granite-greenstone belts of the Liaoning-model, in which the granitic rocks are mainly migmatitic granite and granite-gneiss of migmatitic genesis. The greenstone belts in this area have undergone strong metamorphism. Large amounts of Precambrian geochronological studies have been made with U-Pb isotopic method on zircon; and a new Precambrian geologic time scale has been established. It is also proved that multistage activation of the Early Precambrian basement and the proto-platform took place in Early Proterozoic. Emphases are laid on uranium and thorium abundances and their variations as well as primary uranium contents of rocks in the granite-greenstone terrain and those of the Lower Proterozoic. At the same time, uraninite as accessory mineral in granitic rocks is found to exist more or less. Early Precambrian strata and many kinds of mineral deposits occurring in the strata are in origin chiefly of syngenetic hot brine sedimentation and of submarine extrusive gas-hydrothermal sedimentation superimposed by metamorphism. Metallogenetic features and models of various types of uranium deposits are studied emphatically and compared with similar large deposits abroad. In addition, overall synthetical appraisals are made for this area; and on this basis, prospecting directions and favourable sections of uranium metallization are suggested. (4 refs., 4 tabs.)

    Full Text Available Resource-based cities face unique challenges when undergoing urban transitions because their non-renewable resources will eventually be exhausted. In this article, we introduce a new method of evaluating the urban transition performance of resource-based cities from economic, social and eco-environmental perspectives. A total of 19 resource-based cities in Northeast China are studied from 2003 to 2012. The results show that resource-based cities in Jilin and Liaoning provinces performed better than those in Heilongjiang province. Liaoyuan, Songyuan and Baishan were ranked as the top three resource-based cities; and Jixi, Yichun and Heihe were ranked last. Multi-resource and petroleum resource-based cities performed better than coal and forestry resource-based cities. We also analyzed the factors influencing urban transition performance using the method of the geographic detector. We found that capital input, road density and location advantage had the greatest effects on urban transition performance, followed by urban scale, remaining resources and the level of sustainable development; supporting policies and labor input had the smallest effects. Based on these insights, we have formulated several recommendations to facilitate urban transitions in China’s resource-based cities.

    To explore the factors associated with burnout among female hospital nurses in China. Burnout has been a major concern in the field of occupational health, and yet there has been little research exploring the factors related to burnout among Chinese nurses. Exploring the factors associated with burnout is important in improving nurses' health and the quality of health care services in China. The study population consisted of 1845 female hospital nurses in the Liaoning Province of China. Burnout was measured using the Chinese version of the Maslach Burnout Inventory-General Survey; occupational stress was measured using the Chinese versions of the Job Content Questionnaire and Effort-Reward Imbalance Questionnaire. A general linear regression model was applied to analyse the factors associated with burnout. Mean scores (±SD) were 11.74 (7.14) for emotional exhaustion, 7.12 (5.67) for cynicism and 23.34 (9.60) for self-efficacy. Strong extrinsic effort was the most powerful predictor of emotional exhaustion and cynicism; strong psychological job demands were the most robust predictor of low self-efficacy. The findings suggest that occupational stress was strongly related to burnout among female hospital nurses in China. Occupational stress was identified as the most robust predictor of burnout among Chinese female hospital nurses. Reducing burnout among nurses working in China may require health education, health promotion and occupational training programmes aimed at improving work situations and reducing occupational stress. © 2012 John Wiley & Sons Ltd.

    As a kind of clean energy, wind power has gained rapid development in recent years. Liaoning Province has abundant wind resources and the total installed capacity of wind power is in the forefront. With the large-scale wind power grid-connected operation, the contradiction between wind power utilization and peak load regulation of power grid has been more prominent. To this point, starting with the power structure and power grid installation situation of Liaoning power grid, the distribution and the space-time output characteristics of wind farm, the prediction accuracy, the curtailment and the off-grid situation of wind power are analyzed. Based on the deep analysis of the seasonal characteristics of power network load, the composition and distribution of main load are presented. Aiming at the problem between the acceptance of wind power and power grid adjustment, the scheduling strategies are given, including unit maintenance scheduling, spinning reserve, energy storage equipment settings by the analysis of the operation characteristics and the response time of thermal power units and hydroelectric units, which can meet the demand of wind power acceptance and provide a solution to improve the level of power grid dispatching.

    Full Text Available China’s cities have been undergoing rapid and intense urbanization processes in the past few decades. Shandong is a coastal province which is located in East China with big economy and population scales, and which also plays an important role in the rapid process of China’s modernization. The DMSP/OLS dataset has been widely used for the urban development assessments in long time-series and large spatial scales situations. In this paper, we used a time series of nighttime light data to estimate the landscape spatial pattern changes of cities in Shandong province from 1994 to 2012. Nine landscape metrics were calculated and analyzed to figure out the spatial patterns of urban area developments of the cities in Shandong province. The landscape metrics include the number of patches (NP, the landscape total area (TA, the aggregation index (AI, the largest patch index (LPI, the mean patch area (AREA_MN, the landscape shape index (LSI, the total edge length (TE, the edge density (ED, and the mean radius of gyration (GYRATE_MN. The experimental results reveal that, in 1994–2012, the total urban area of cities in Shandong province expanded for 1.17 times, the average urban area increased by about 93.00%, the average annual growth rate of the TE metric is 2.67 %, while the ED metric decreased about 1.44 % annually. Bigger cities in this area show relative slower urbanization development processes, such as Jinan and Qingdao. Coastal cities represented much more rapid expansion velocities than inland cities. In the middle area of Shandong province, the connectivity between developed urban areas was constantly increased.

The landscape metrics include the number of patches (NP), the landscape total area (TA), the aggregation index (AI), the largest patch index (LPI), the mean patch area (AREA_MN), the landscape shape index (LSI), the total edge length (TE), the edge density (ED), and the mean radius of gyration (GYRATE_MN). The experimental results reveal that, in 1994-2012, the total urban area of cities in Shandong province expanded for 1.17 times, the average urban area increased by about 93.00%, the average annual growth rate of the TE metric is 2.67 %, while the ED metric decreased about 1.44 % annually. Bigger cities in this area show relative slower urbanization development processes, such as Jinan and Qingdao. Coastal cities represented much more rapid expansion velocities than inland cities. In the middle area of Shandong province, the connectivity between developed urban areas was constantly increased.

    During the Twelve Five period, China promulgated industrial policies promote the energy-intensive industries relocate to coastal areas in order to utilize marine shipping resources. Consequently, some major state-owned steel and petrochemical enterprises have relocated and resulted in a large scale coastal area development. Restricted by the port construction, most of the coastal industrial areas are located in the outer suburbs. To balance between employment and housing, new industrial coastal towns were constructed. In this paper, we adopt a case-study approach to analysis some typical industrial coastal towns of Liaoning Province situated in the Bohai Bay, which is currently under rapid economic growth. Our investigations reflect the common phenomenon of long distance commuting and massive amount of vacant residences. More specifically, large plant relocation caused hundreds of kilometers of daily commute and enterprises had to provide housing subsidies and education incentives to motivate employees to relocate to coastal areas. Nonetheless, many employees still refuse to relocate due to job stability, diverse needs of family members and access to convenient services. These employees averaged 4 hours of commute daily and some who lived further had to reside in temporary industrial housing units and subject to long-term family separation. As a result, only a small portion of employees purchase new coastal residences but mostly for investment and retirement purposes, leading to massive vacancy and ghost-town phenomenon. In contrast to the low demand, coastal areas tend to develop large amount of residences prior to industrial relocation, which may be directly related to local government finances. Some local governments have sold residential land to developers to general revenue to support the subsequent industrial development. Subject to the strong preference of ocean- view, residential housing developers tend to select coast-line land to construct new residential

    Maize water suitability (MWS) model was developed at growth stage scale. Frequency and severity of drought were evaluated by combining MWS estimates and agricultural meteorological drought indexes. The MWS at each growth stage was calculated by using maize observational data and conventional meteorological data at 52 sites in Liaoning during the period from 1981 to 2010. Based on the climatic trend and abrupt change analysis, spatiotemporal dynamics of MWS were investigated. Meanwhile, occurrence of agricultural drought and its severity were also estimated. The results showed that the variation of MWS largely differed at different growth stages. Climatic abrupt change happened in 1994, 1996 and 1999 at the stages of emergence to seven leaves (II), jointing to tasseling (IV) and physiological maturity to maturity (VI). During the past 30 years, MWS showed an obvious increasing trend at the stages of sowing to emergence(I) , seven leaves to jointing(III), IV and tasseling to physiological maturity(V), while it showed a decreasing trend at the stages of II and VI, and that at VI stage was statistically significant. In addition, the climatic trend of MWS showed apparently spatial variability. The frequencies of drought at different severities varied with maize growth stages. Areas of high variability of MWS were located in the Northwest and South of Liaoning at the stages of I , II , III and VI, where were also the regions of high frequency of mid- and severe-drought. At the stages of IV and V, the frequency of drought was low and only light- and mid-drought occurred in few areas. In conclusion, the regional mean MWS could be capable to reasonably assess the agricultural drought in Liaoning at the regional scale.

    Larch is the main timber species of forest plantations in North China. Imbalance in nutrient cycling in soil emerged due to single species composition and mono system structure of plantation. Thus it is necessary to grasp its biomass and nutrients allocation for scientific management and nutrient cycling studies of larch plantation. We measured aboveground biomass (stem, branch, bark and leaf) and nutrient concentrations (C, N, P, K, Ca, Mg, Fe, Mn, Cu and Zn), and analyzed the patterns of accumulation and distribution of 19-year-old larch plantation with diameter at breast height of 12. 8 cm, tree height of 15. 3 m, and density of 2308 trees · hm(-2), in a montane region of eastern Liaoning Province, China. The results showed that aboveground biomass values were 70.26 kg and 162.16 t · hm(-2) for the individual tree of larch and the stand, respectively. There was a significant difference between biomass of the organs, and decreased in the order of stem > branch > bark > leaf. Nutrient accumulation was 749.94 g and 1730.86 kg · hm(-2) for the individual tree of larch and the stand, respectively. Nutrient accumulation of stem was significantly higher than that of branch, bark and leaf, whether it was macro-nutrient or micro-nutrient. Averagely, 749.94 g nutrient elements would be removed from the system when a 19-year-old larch tree was harvested. If only the stem part was removed from the system, the removal of nutrient elements could be reduced by 40.7%.

    To determine the incidence of polycystic ovary syndrome (PCOS) among Han women of reproductive age in Liaoning Province in Northeastern China, based on the Revised Rotterdam 2003 criteria. A retrospective cohort study was carried out on 1,600 women using questionnaires, physical examination, ultrasonography, and biochemical indices (aged = 19 to 45 years; n = 1,600). PCOS patients were identified using the Revised Rotterdam 2003 criteria. A total of 132 Han women of reproductive age were diagnosed with PCOS, with a prevalence of 8.25%. The prevalence of menstrual dysfunction was as follows: 97 patients (73.48%) had abnormal menstruation, three (2.27%) had polymenorrhea, and 94 (71.21%) had oligomenorrhea. Up to 64 patients (48.48%) had androgen excess, 42 (31.82%) had biochemical evidence of androgen excess, and 34 (25.76%) had clinical androgen excess. Up to 34 patients (25.76%) were obese (body mass index [BMI] > or = 25) and 19 (14.39%) had hirsutism (F-G scoring > or = 6). A total of 127 patients (96.22%) were diagnosed with PCOS via ultrasonography, 67 of whom (50.76%) had a unilateral polycystic ovary and 60 (45.46%) had bilateral polycystic ovaries. The prevalence of PCOS in this study population was 8.25%, with an infertility rate of 27.8%. The classical manifestation of PCOS is PCO, abnormal menstruation, and obesity. The high-risk factors of PCOS include high free testosterone index, homeostasis model assessment-insulin resistance (HOMA-IR), increased serum testosterone and androstenedione, decreased sex hormone-binding globulin, long history of infertility, menarche later than 16 years old, and failure to have regular menstruation within two years.

    To clarify the diabetes prevalence trends among the rural population in northern China. All eligible permanent residents aged ≥ 35 years in selected rural villages of Liaoning province were invited to participate in the study. A total of 11 600 people completed all questionnaires and were included in the study. The response rate was 85.3%. Fasting plasma glucose levels were measured after at least 12 h of fasting and diabetes was diagnosed according to WHO criteria, i.e. fasting plasma glucose ≥ 7 mmol/l and/or being on treatment for diabetes. Impaired fasting glucose was defined according to the 1997 and the 2010 American Diabetes Association (ADA) criteria (6.1-6.9 and 5.6-6.9 mmol/l, respectively). Previous diagnoses of diabetes were assessed on the basis of self-reports. The prevalence of diabetes among adults in the rural population was 10.6% (10.0% in men and 11.1% in women). The prevalence of impaired fasting glucose was 13.0 and 36.1% according to the 1997 and the 2010 ADA criteria, respectively. The prevalence of previously diagnosed diabetes was 4.3% among the whole population (3.3% in men and 5.1% in women). The prevalence of previously diagnosed diabetes was 34.8% in men and 50.2% in women. Only 29.6% of men and 42% of women with diabetes had taken oral hypoglycaemic agents or insulin to lower their blood sugar. In multivariate analysis, age, drinking habits, BMI, dyslipidaemia and family history of diabetes were identified as independent risk factors for diabetes, and occupational physical activity, smoking and lean meat intake were identified as independent protective factors for diabetes. The prevalence of diabetes and impaired fasting glucose were found to be high in this rural population. Although the rate of treatment of people with diabetes has increased, the glycaemic control rate was still at a low level. © 2014 The Authors. Diabetic Medicine © 2014 Diabetes UK.

    Full Text Available In this paper, the spatio-temporal distribution characteristics of nitrogen dioxide (NO2 were investigated using data obtained routinely from air quality monitoring stations located in seven major cities and nine provinces in Korea for the period 1998 to 2003. The results indicate that annual trends in NO2 concentrations generally reflect changes in environmental conditions, while exhibiting cyclic and systematic patterns across seasons. Its wintertime concentrations were most prominent, with concentrations decreasing gradually across spring, fall, and summer. If concentration patterns are examined among different cities and/or provinces, the highest mean values were found from the Capital city, Seoul (34.7 ppb and the surrounding province, Gyunggi (30.2 ppb. In contrast, remarkably reduced NO2 concentrations were seen in such regions as the remote island, Jeju and Jeonnam province with mean values of 17.5 and 16.5 ppb, respectively. The overall results of our study indicate that there are strong geographical gradients in NO2 distributions to exhibit strongly polluted patterns consistently in densely populated urban areas (e.g., major city, compared to large rural areas (e.g., province.

    In China, the prevalence of hypertension is increasing and is showing an epidemic accelerating trend. However, there is a lack of studies reporting the hypertension status of rural residents with minimum living allowances. We performed a cross-sectional study including 11,435 (5285 men and 6150 women) from the general population aged ≥35 years in the Liaoning Province of China from 2012 to 2013, of which 1258 (11.0%) participants came from minimal assurance families. Anthropometric measurements, laboratory examinations and self-reported lifestyle factor information were collected by trained personnel. Multivariate logistic regression was used to detect the association between socioeconomic status (SES) and the risk of hypertension. We found that the prevalence of hypertension was as high as 61.9% in participants from minimal assurance families and the odd ratio for hypertension was 1.32 (95% CI: 1.15-1.52). The awareness, treatment, and control rates among treated hypertensive participants did not increase with higher level of income and education. In the total sample, the lower income levels increased the risk for hypertension, but education didn't show a significant association with hypertension. Thus, there is a severe hypertension situation in the Liaoning rural population of minimal assurance families, which need more attention and prevention and control measures for hypertension.

    Urban public health is an important global issue and receives public concern. The urban ecosystem health (UEH) indicator system was constructed with 27 assessment indicators selected from vigor, organization, resilience, service function, and population health, then the matter element analysis (MEA) and analytic hierarchy process (AHP) weighting method were used to assess the UEH of each city in Jiangsu Province during the period of 2000-2014. The results show that the overall ecosystem health status of each city shows continuous improvement. The UEH status of each city gradually transferred from poor, general, and medium condition to good and excellent condition. From the perspective of spatial distribution, the city's UEH showing a steady status after increasing for 10 years, and their spatial variations have gradually reduced. The UEH status in Southern Jiangsu and Central Jiangsu was better than that of Northern Jiangsu Province. From each component point of view, the vigor, resilience, and population health of each city in Jiangsu Province showed a trend of continuous improvement, while the organization and service function first increased and then decreased. The common limiting factors of UEH in Jiangsu Province were Engel's coefficient of urban households, number of beds of hospitals, health centers per 10,000 people, and total investment in the treatment of environmental pollution as percent GDP. These results help decision makers to make suitable decisions to maintain the UEH of each city in Jiangsu Province.

    By using Granier' s thermal dissipation probe, the sap flow of poplar in a poplar-maize agroforestry system in west Liaoning was continuously measured, and as well, the environmental factors such as air temperature, air humidity, net radiation, wind speed, soil temperature, and soil moisture content were synchronically measured. Based on the sap flow data, the canopy conductance of poplar was calculated with simplified Penman-Monteith equation. In the study area, the diurnal variation of poplar' s canopy conductance showed a "single peak" curve, whereas the seasonal variation showed a decreasing trend. There was a negative logarithm relationship between the canopy conductance and vapor pressure deficit, with the sensitivity of canopy conductance to vapor pressure deficit change decreased gradually from May to September. The canopy conductance had a positive relationship with solar radiation. In different months, the correlation degree of canopy conductance with environmental factors differed. The vapor pressure deficit in the whole growth period of poplar was the most significant environmental factor correlated with the canopy conductance.

    With the development of urbanization in China, buildings consumed lots of material and energy. How to estimate carbon emission of buildings is an important scientific problem. Carbon footprint of the central Liaoning agglomeration was studied with carbon footprint approach, geographic information system (GIS) and high-resolution remote sensing (HRRS) technology. The results showed that the construction carbon footprint coefficient of central Liaoning urban agglomeration was 269.16 kg·m -2 . The approach of interpreting total building area and spatial distribution with HRRS was effective, and the accuracy was 89%. The extraction approach was critical for total carbon footprint and spatial distribution estimation. The building area and total carbon footprint of central Liaoning urban agglomeration in descending order was Shenyang, Anshan, Fushun, Liao-yang, Yingkou, Tieling and Benxi. The annual average increment of footprint from 2011 to 2013 in descending order was Shenyang, Benxi, Fushun, Anshan, Tieling, Yingkou and Liaoyang. The accurate estimation of construction carbon footprint spatial and its distribution was of significance for the planning and optimization of carbon emission reduction.

    The results of a first phase of an indoor survey in a total of 1610 dwellings distributed in nine cities of the Eastern and the Western provinces of Saudi Arabia are presented. The objective of this radon survey was to obtain representative indoor radon data for seven cities in the Eastern province, Khafji, Hafr Al-Batin, Abqaiq, Qatif, Al-Ahsa, Dammam and Khobar and to compare this with two cities in the Western province, Madina and Taif. So far, detailed radon data is not available for Saudi Arabia; therefore, this radon survey provides a base line for Saudi Arabia in the Radon World Atlas. On average, 200 indoor radon dosemeters were distributed in each city and placed for a period of one year starting from May 2001 to May 2002. The total number of collected dosemeters was 847. A total of 724 houses and 98 schools were covered in this survey. The results of the survey in the cities showed that the overall minimum, maximum and average radon concentrations were 1, 137 and 22 Bq m {sup -3}, respectively. Geometric mean and geometric standard deviations of the radon distribution were found to be 18 and 1.92, respectively. In one of the dwellings in Qatif city, radon concentration, measured by a passive system and then confirmed by an active system, was found to be 535 {+-} 23 and 523 {+-} 22 Bq m {sup -3}, respectively. The result of a radon survey in 98 schools showed that the minimum, maximum and average radon concentrations were 1, 70 and 19 Bq m{sup -3}, respectively. The average radon concentration for each city was also determined. The lowest average radon concentration (8 Bq m{sup -3}) was found in Al-Ahsa while the highest average concentration (40 Bq m {sup -3}) was found in Khafji. (author)

    Serious land desertification and sandified threaten the urban ecological security and the sustainable economic and social development. In recent years, a large number of mobile sand dunes in Horqin sandy land flow into the northwest of Liaoning Province under the monsoon, make local agriculture suffer serious harm. According to the characteristics of desertification land in northwestern Liaoning, based on the First National Geographical Survey data, the Second National Land Survey data and the 1984-2014 Landsat satellite long time sequence data and other multi-source data, we constructed a remote sensing monitoring index system of desertification land in Northwest Liaoning. Through the analysis of space-time-spectral characteristics of desertification land, a method for multi-spectral remote sensing image recognition of desertification land under time-space constraints is proposed. This method was used to identify and extract the distribution and classification of desertification land of Chaoyang City (a typical citie of desertification in northwestern Liaoning) in 2008 and 2014, and monitored the changes and transfers of desertification land from 2008 to 2014. Sandification information was added to the analysis of traditional landscape changes, improved the analysis model of desertification land landscape index, and the characteristics and laws of landscape dynamics and landscape pattern change of desertification land from 2008 to 2014 were analyzed and revealed.

    Full Text Available Liaoning cashmere goat is a famous goat breed for cashmere wool. In order to increase the transcriptome data and accelerate genetic improvement for this breed, we performed de novo transcriptome sequencing to generate the first expressed sequence tag dataset for the Liaoning cashmere goat, using next-generation sequencing technology.Transcriptome sequencing of Liaoning cashmere goat on a Roche 454 platform yielded 804,601 high-quality reads. Clustering and assembly of these reads produced a non-redundant set of 117,854 unigenes, comprising 13,194 isotigs and 104,660 singletons. Based on similarity searches with known proteins, 17,356 unigenes were assigned to 6,700 GO categories, and the terms were summarized into three main GO categories and 59 sub-categories. 3,548 and 46,778 unigenes had significant similarity to existing sequences in the KEGG and COG databases, respectively. Comparative analysis revealed that 42,254 unigenes were aligned to 17,532 different sequences in NCBI non-redundant nucleotide databases. 97,236 (82.51% unigenes were mapped to the 30 goat chromosomes. 35,551 (30.17% unigenes were matched to 11,438 reported goat protein-coding genes. The remaining non-matched unigenes were further compared with cattle and human reference genes, 67 putative new goat genes were discovered. Additionally, 2,781 potential simple sequence repeats were initially identified from all unigenes.The transcriptome of Liaoning cashmere goat was deep sequenced, de novo assembled, and annotated, providing abundant data to better understand the Liaoning cashmere goat transcriptome. The potential simple sequence repeats provide a material basis for future genetic linkage and quantitative trait loci analyses.

    The velocity structure of the crust beneath Liaoning province and the Bohai sea in China was imaged using ambient seismic noise recorded by 73 regional broadband stations. All available three-component time series from the 12-month span between January and December 2013 were cross-correlated to yield empirical Green's functions for Rayleigh and Love waves. Phase-velocity dispersion curves for the Rayleigh waves and the Love waves were measured by applying the frequency-time analysis method. Dispersion measurements of the Rayleigh wave and the Love wave were then utilized to construct 2D phase-velocity maps for the Rayleigh wave at 8-35 s periods and the Love wave at 9-32 s periods, respectively. Both Rayleigh and Love phase-velocity maps show significant lateral variations that are correlated well with known geological features and tectonics units in the study region. Next, phase dispersion curves of the Rayleigh wave and the Love wave extracted from each cell of the 2D Rayleigh wave and Love wave phase-velocity maps, respectively, were inverted simultaneously to determine the 3D shear wave velocity structures. The horizontal shear wave velocity images clearly and intuitively exhibit that the earthquake swarms in the Haicheng region and the Tangshan region are mainly clustered in the transition zone between the low- and high-velocity zones in the upper crust, coinciding with fault zones, and their distribution is very closely associated with these faults. The vertical shear wave velocity image reveals that the lower crust downward to the uppermost mantle is featured by distinctly high velocities, with even a high-velocity thinner layer existing at the bottom of the lower crust near Moho in central and northern the Bohai sea along the Tanlu fault, and these phenomena could be caused by the intrusion of mantle material, indicating the Tanlu fault could be just as the uprising channel of deep materials.

    To determine the contents of lignans, crude polysaccharides (CP) and total phenolic compounds (TPC) of Schisandra chinensis from various habitats in Liaoning province and evaluate their quality and free radical scavenging (FRS) activity. Contents of schisandrol, deoxyschizandrin and schisandrin B were determined by RP-HPLC. Contents of TPC, CP and FRS activity were determined by Folin-Cicalteu's, phenol-sulfuric acid and DPPH x method, respectively. Sample from Liaoyang city had the highest contents of lignans (21.75 mg/g); Sample from Shenbei New district of Shenyang city had the highest contents of CP (88.72 mg/g); Sample from Guanmenshan district of Benxi city had the highest contents of TPC and FRS activity (26.06 mg/g and 86.3%, respectively). Linear regression analysis results showed that contents of TPC had higher correlation coefficient with FRS activity than that of lignans. Their linear regression equations were Y = 1.3677X + 46.97, R2 = 0.6869 and Y = 2.5916X + 57.927, R2 = 0.1747 for TPC and lignans with FRS activity, respectively. The contents of lignans, CP and TPC are significantly different from samples collected from various habitats in Liaoning province. The main antioxidative substances are TPC, and lignans have no significant correlation with FRS activity.

    For the purpose of working out a comprehensive master plan for application of the coal utilization system, the paper surveyed and studied the coal utilization system in terms of environmental measures and efficiency improvement in the utilization of coal. As a result of the discussion with NEDO and the National Planning Committee of China, Liaoning Province (the whole China) and Shenyang City were selected as a model area and a model city for the survey and study. As energy conservation measures taken in the former, desirable are intensifying/capacity-increase of boilers, kilns, etc. and adoption of new-type/high-efficient equipment. Also expected are reinforcement of combustion control and improvement of efficiency by using coal preparation, industrial use coal briquette, etc. Measures taken in the latter are the same as those taken in the whole China. As SOx reduction measures for Liaoning Province, desirable is installation of dry-type desulfurization equipment and simple desulfurization equipment. As dust prevention measures for it, desirable is installation of electrostatic precipitators or high-functional bag filters. SOx reduction measures for Shenyang City are the same as those taken in the whole China. SOx can be reduced by using coal-prepared low-sulfur coal and industrial use coal briquette added with desulfurizing agent. 88 figs., 163 tabs.

    Concentrations of 13 perfluoroalkyl substances (PFASs) were quantified in 79 surface soil samples from 17 coastal cities in three provinces and one municipality along the Bohai and Yellow Seas. The ∑PFASs concentrations ranged from less than limitation of quantification (LOQ) to 13.97 ng/g dry weight (dw), with a mean of 0.98 ng/g dw. The highest concentration was observed along the Xiaoqing River from Shandong province, followed by that from the Haihe River in Tianjin (10.62 ng/g dw). Among four regions, ∑PFASs concentrations decreased in the order of Tianjin, Shandong, Liaoning and Hebei, which was consistent with levels of urbanization. Fluorine chemical industries allocated in Shandong and Liaoning played important roles in terms of point emission and contamination of PFASs, dominated by perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). Intensive anthropogenic activities involved in urbanization possibly resulted in increasing releases of PFASs from industrial and domestic sources. Copyright © 2015 Elsevier Ltd.

    The hand foot and mouth disease (HFMD) is a human syndrome caused by intestinal viruses like that coxsackie A virus 16, enterovirus 71 and easily developed into outbreak in kindergarten and school. Scientifically and accurately early detection of the start time of HFMD epidemic is a key principle in planning of control measures and minimizing the impact of HFMD. The objective of this study was to establish a reliable early detection model for start timing of hand foot mouth disease epidemic in Dalian and to evaluate the performance of model by analyzing the sensitivity in detectability. The negative binomial regression model was used to estimate the weekly baseline case number of HFMD and identified the optimal alerting threshold between tested difference threshold values during the epidemic and non-epidemic year. Circular distribution method was used to calculate the gold standard of start timing of HFMD epidemic. From 2009 to 2014, a total of 62022 HFMD cases were reported (36879 males and 25143 females) in Dalian, Liaoning Province, China, including 15 fatal cases. The median age of the patients was 3 years. The incidence rate of epidemic year ranged from 137.54 per 100,000 population to 231.44 per 100,000population, the incidence rate of non-epidemic year was lower than 112 per 100,000 population. The negative binomial regression model with AIC value 147.28 was finally selected to construct the baseline level. The threshold value was 100 for the epidemic year and 50 for the non- epidemic year had the highest sensitivity(100%) both in retrospective and prospective early warning and the detection time-consuming was 2 weeks before the actual starting of HFMD epidemic. The negative binomial regression model could early warning the start of a HFMD epidemic with good sensitivity and appropriate detection time in Dalian.

    The Yanliao Biota of northeastern China comprises the oldest feathered dinosaurs, transitional pterosaurs, as well as the earliest eutherian mammals, multituberculate mammals, and new euharamiyidan species that are key elements of the Mesozoic biotic record. Recent discovery of the Yanliao Biota in the Daxishan section near the town of Linglongta, Jianchang County in western Liaoning Province have greatly enhanced our knowledge of the transition from dinosaurs to birds, primitive to derived pterosaurs, and the early evolution of mammals. Nevertheless, fundamental questions regarding the correlation of fossil-bearing strata, rates of dinosaur and mammalian evolution, and their relationship to environmental change in deep time remain unresolved due to the paucity of precise and accurate temporal constraints. These limitations underscore the importance of placing the rich fossil record of Jianchang within a high-resolution chronostratigraphic framework that has thus far been hampered by the relatively low precision of in situ radioisotopic dating techniques. Here we present high-precision U-Pb zircon geochronology by the chemical abrasion isotope dilution thermal ionization mass spectrometry (CA-ID-TIMS) from three interstratified ash beds previously dated by secondary-ion mass spectrometry (SIMS) technique. The results constrain the key fossil horizons of the Daxishan section to an interval spanning 160.89 to 160.25 Ma with 2σ analytical uncertainties that range from ±46 to ±69 kyr. These data place the Yanliao Biota from Jianchang in the Oxfordian Stage of the Late Jurassic, and mark the Daxishan section as the site of Earth's oldest precisely dated feathered dinosaurs and eutherian mammals.

    As the largest developing country in the world, China has witnessed fast-paced urbanization over the past three decades with rapid economic growth. In fact, urbanization has been not only shown to promote economic growth and improve the livelihood of people but also can increase demands of regional logistics. Therefore, a better understanding of the relationship between urbanization and regional logistics is important for China's future sustainable development. The development of urban residential area and heterogeneous, modern society as well regional logistics are running two abreast. The regional logistics can promote the development of new-type urbanization jointly by promoting industrial concentration and logistics demand, enhancing the residents' quality of life and improving the infrastructure and logistics technology. In this paper, the index system and evaluation model for evaluating the development of regional logistics and the new-type urbanization are constructed. Further, the econometric analysis is utilized such as correlation analysis, co-integration test, and error correction model to explore relationships of the new-type urbanization development and regional logistics development in Liaoning Province. The results showed that there was a long-term stable equilibrium relationship between the new-type urbanization and regional logistics. The findings have important implications for Chinese policymakers that on the path towards a sustainable urbanization and regional reverse, this must be taken into consideration. The paper concludes providing some strategies that might be helpful to the policymakers in formulating development policies for sustainable urbanization.

    The aim of this study is to shed light on the hydrogeochemical characteristics of karst underground waters at shallow depth in Guiyang City, Guizhou Province with an emphasis on the geochemistry of major elements. Guiyang City bears abundant underground waters and it is also an important representative of the karst areas throughout the world. Ca 2+ and Mg 2+ are the dominant cations, accounting for 81%- 99.7% of the total, and HCO -3 and SO 2- 4 are the dominant anions. Weathering of limestones and dolostones is the most important factor controlling the hydrogeochemistry of underground waters, and weathering of sulfate and evaporite rocks is less important. Moreover, the precipitation and human activities also have a definite influence on the hydrogeochemistry of underground waters in the region studied.

    107 kinds of C₂-C₁₂ volatile organic compound (VOC) mass concentrations and profiles for four types of coal-fired stationary sources in Liaoning Province were studied by a dilution sampling system and GC-MS analysis method, which are of significant importance with regard to VOC emissions in northeast of China. The results showed that there were some differences among these VOC source profiles. The total mass concentrations of analyzed 107 VOC species varied from 10,917 to 19,652 μg m(-3). Halogenated hydrocarbons exhibited higher mass percentages for the VOC source profiles of iron smelt (48.8%) and coke production plant (37.7%). Aromatic hydrocarbons were the most abundant in heating station plant (69.1%). Ketones, alcohols and acetates held 45.0% of total VOCs in thermal power plant. For non-methane hydrocarbons (NMHCs), which are demanded for photochemical assessment in the USA, toluene and n-hexane were the most abundant species in the iron smelt, coke production and thermal power plant, with the mass percentages of 64.8%, 52.7% and 38.6%, respectively. Trimethylbenzene, n-propylbenzene and o,m-ethyltoluene approximately accounted for 70.0% in heating station plant. NMHCs emitted from coke production, iron smelt, heating station and power plant listed above presented different chemical reactivities. The average OH loss rate of NMHCs from heating station, was 4 to 5.6 times higher than that of NMHCs from iron smelt, coke production and power plant, which implies that VOCs emitted from heating station in northeast of China should be controlled firstly to avoid photochemical ozone pollution and protect human health. There are significant variations in the ratios of benzene/toluene and m, p-xylene/ethylbenzene of these coal-fired source profiles. The representativeness of the coal-fired sources studied and the VOC samples collected should be more closely examined. The accuracy of VOC source profiles related to coal-fired processes is highly dependent on

    Concentrations of 19 PFASs in riverwater, coastal wastewater and effluents from WWTPs which were directly discharged into the Bohai Sea of China were measured and their inputs to this sea area were calculated accordingly. For riverwater samples, the total PFAS concentrations ranged from 13.1 to 69 238 ng/L. PFAS levels in riverwater collected from Liaoning Province were comparable to those from Shandong Province, while they were two orders of magnitude greater than those from Hebei Province and the city of Tianjin. The dominant PFAS patterns were spatially different. PFBS and PFOA were the predominant PFASs in riverwater samples at sites where fluorochemical industry parks are located in Liaoning Province and Shandong Province, respectively. For other sites, PFOA and PFOS were the most abundant PFASs. In contrast, the total PFAS concentrations in coastal wastewater and effluent samples ranged from 16.7 to 7 522 ng/L and from 13.1 to 319 ng/L, respectively. PFOA was dominant in these samples. Inputs of PFASs to the Bohai Sea via riverine flow, discharge of coastal wastewater and effluents were estimated to be 87.3 tons per year. As compared with coastal wastewater and effluent discharge, riverine input was a major source for the PFAS pollution in the Bohai Sea except for PFBS. Copyright © 2016 Elsevier Ltd.

    A dendrochronological profile was generated from Chinese pines ( Pinus tabulaeformis Carr.) in the Qianshan Mountains in northeastern China. Based on correlation analyses, the pattern of precipitation from March to June ( P 36 ) was reconstructed using a simple linear model, which explained 42.7% of the total variance in observed precipitation from 1951 to 2012. The reconstructed P 36 series revealed a consistently increasing trend in precipitation during the twentieth century in the Qianshan Mountains. The reconstructed data showed trends that were similar to those in the variation in trends for March-June precipitation observed at the Shenyang station, the reconstructed January-May precipitation trends in Shenyang City, and the reconstructed average June-September relative humidity for Yiwulü Mountain. The reconstructed data also showed good agreement with the droughts reported in historical documents and recorded by meteorological stations in Liaoning. Spatial correlation analyses show that the reconstructed data reflect the variability in precipitation that occurs over much of northeastern China. In addition, our reconstruction showed a significant periodicity. The significant correlations between the reconstructed P 36 and the El Niño-Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO) and sunspot numbers indicate that precipitation variability in the Qianshan Mountain region is probably driven by extensive atmosphere-sea interactions and solar activities.

    The purpose of this study was to determine the concentrations and health risk of heavy metals in urban soils from a steel industrial district in China. A total of 115 topsoil samples from Anshan city, Liaoning, Northeast China were collected and analyzed for Cr, Cd, Pb, Zn, Cu, and Ni. The geoaccumulation index (Igeo), pollution index (PI), and potential ecological risk index (PER) were calculated to assess the pollution level in soils. The hazard index (HI) and carcinogenic risk (RI) were used to assess human health risk of heavy metals. The average concentration of Cr, Cd, Pb, Zn, Cu, and Ni were 69.9, 0.86, 45.1, 213, 52.3, and 33.5mg/kg, respectively. The Igeo and PI values of heavy metals were in the descending order of Cd>Zn>Cu>Pb>Ni>Cr. Higher Igeo value for Cd in soil indicated that Cd pollution was moderate. Pollution index indicated that urban soils were moderate to highly polluted by Cd, Zn, Cu, and Pb. The spatial distribution maps of heavy metals revealed that steel industrial district was the contamination hotspots. Principal component analysis (PCA) and matrix cluster analysis classified heavy metals into two groups, indicating common industrial sources for Cu, Zn, Pb, and Cd. Matrix cluster analysis classified the sampling sites into four groups. Sampling sites within steel industrial district showed much higher concentrations of heavy metals compared to the rest of sampling sites, indicating significant contamination introduced by steel industry on soils. The health risk assessment indicated that non-carcinogenic values were below the threshold values. The hazard index (HI) for children and adult has a descending order of Cr>Pb>Cd>Cu>Ni>Zn. Carcinogenic risks due to Cr, Cd, and Ni in urban soils were within acceptable range for adult.

    Full Text Available The study intended to explore planning strategies gaps in ten-year perspective and medium-term development framework plans for agro-based industrial development in secondary cities of Sindh Province, Pakistan. Document review and key informant interviews survey techniques were used for data collection. A total of 30 interviews were conducted from agro-based officials. The SWOT analysis technique was applied for data analysis. The results revealed the weaknesses of high priority for textile and sugar industries, lack of planning strategies for agro-based development in secondary cities, dependency on federal government for development funds and absence of finances to implement plans. The threats were unavailability of strategic agro-based infrastructure facilities in secondary cities, centralized planning system, cross border threats such as the war in Afghanistan and migration of Afghan refugees, weak law and order situation and diversion of development budget for defense activities. The study suggests decentralization of powers and robust planning strategies in the development plans to strengthen secondary cities of Sindh Province economically.

    Kurdistan Province, with an area of 28,203 square kilometers, is located in a mountainous area in the western part of Iran. From 1967 to 1997, the urban population in the major eight cities of the Kurdistan Province-namely, Baneh, Bijar, Divan Darreh, Saghez, Sanandaj, Ghorveh, Kamyaran, and Marivan-increased from 102,250 to 705,715. The proportion of the population residing in urban areas increased 90 percent during this period. In most of the cities, solid waste handling remains primitive, and well-organized procedures for it have not been established. Traditional methods of disposal, with marginal inclusion of modern conveniences, appear to be the common practice. In general, the shortcomings of the prevailing practices can be summarized as follows: The municipal solid waste management systems (MSWMSs) in this province include unsegregated collection and open dumping of municipal solid wastes. Separation of municipal solid waste in this province is in the hands of scavengers. The MSWMSs in this province lack essential infrastructure. Thus, design and implementation of modern MSWMSs in this province are essential. Principal criteria for and methods of implementing these systems are as follows: (1) rationally evaluating all functional elements so that they operate in a steady-state or equilibrium manner; (2) creating all support elements for the MSWMS in each city; (3) introducing gradual privatization of MSWMS activities; (4) creating guidelines, regulations, and instructions for all elements of MSWMSs; and (5) giving priorities to source separation and recycling programs. This paper reviews the present status of MSWMSs in eight major cities of Kurdistan Province and outlines the principle guidelines and alternatives for MSWMSs.

    Fusarium species, which can produce mycotoxins, are the predominant pathogens causing maize ear rot, a disease that results in severe economic losses and serves as a potential health risk for humans and animals. A survey was conducted in 2012 to investigate the contamination of maize by Fusarium species and fumonisins B1 and B2. A total of 250 maize samples were randomly collected from nine provinces (Hebei, Shanxi, Inner Mongolia, Yunnan, Sichuan, Guizhou, Heilongjiang, Liaoning and Ningxia) in China. Fusarium species were isolated and identified using morphological (electron microscope) and molecular methods (polymerase chain reaction (PCR) and sequencing). Fumonisins B1 and B2 were analysed using high-performance liquid chromatography with fluorescence detection (HPLC-FLD) with OPA (2-Mercaptoethanol, o-phthaldialdehyde) post-column derivatisation. A total of 2321 Fusarium isolates (20.7%) were obtained from all the samples. These isolates included nine Fusarium species, namely, F. graminearum, F. verticillioides, F. subglutinans, F. proliferatum, F. temperatum, F. oxysporum, F. equiseti, F. meridionale and F. chlamydosporum. The incidence of occurrence of Fusarium species in Guizhou was the highest, while in Inner Mongolia it was the lowest. F. verticillioides was the dominant species of maize ear rot in Liaoning, Sichuan, Hebei and Ningxia. F. graminearum was the dominant species in Yunnan, Guizhou and Shanxi. F. subglutinans was the dominant species in Heilongjiang. F. verticillioides and F. graminearum percentages were the same in Inner Mongolia. The incidence of fumonisins in Liaoning was high (up to 81.0%) and in Heilongjiang low (up to 10.3%). Except Shanxi, more than 50% of maize samples from other provinces were contaminated with fumonisins, with concentrations less than 500 ng g(-1). About 33% of maize samples from Yunnan were contaminated with high levels of fumonisins, and average of fumonisin levels were 5191 ng g(-1). Fusarium species causing maize

    By using Granier's thermal dissipation probe, the sap flow velocity of the poplars in agroforestry system in west Liaoning was continuously measured, and the microclimate factors were measured synchronously. Dislocation contrast method was applied to analyze the sap flow velocity and corresponding air temperature, air humidity, net radiation, and vapor pressure deficit to discuss the time lag effect between poplar' s sap flow velocity and microclimate factors on sunny days. It was found that the poplar's sap flow velocity advanced of air temperature, air humidity, and vapor pressure deficit, and lagged behind net radiation. The sap flow velocity in June, July, August, and September was advanced of 70, 30, 50, and 90 min to air temperature, of 80, 30, 40, and 90 min to air humidity, and of 90, 50, 70, and 120 min to vapor pressure deficit, but lagged behind 10, 10, 40, and 40 min to net radiation, respectively. The time lag time of net radiation was shorter than that of air temperature, air humidity, and vapor pressure. The regression analysis showed that in the cases the time lag effect was contained and not, the determination coefficients between comprehensive microclimate factor and poplar's sap flow velocity were 0.903 and 0.855, respectively, indicating that when the time lag effect was contained, the determination coefficient was ascended by 2.04%, and thus, the simulation accuracy of poplar's sap flow velocity was improved.

    Resource over-exploitation and resource depletion have received increasing attentions, especially for industrial regions. In this paper an innovative method that combines emergy analysis and an IPAT (Human Impact Population Affluence Technology) equation is developed in order to create an integrated framework for uncovering the driving forces on resource consumption in one industrial region. Liaoning province, one of the old heavy industrial bases in China, is selected as the case study region. The main results show that total emergy of Liaoning province increased from 9.25E + 23 sej in 2002 to 1.92E + 24 sej in 2012, with 165% growth on non-renewable emergy and 250% growth on imported emergy. Regional emergy/RMB ratio was higher than other developed regions and the average value of China, indicating that this province consumed more local free non-renewable resources to support its own development. The lower ESI (emergy sustainability index) indicates that Liaoning province's sustainability is still weak and far away from sustainable development. IPAT analysis further identifies that rapid economic growth was the main driving force to increase its total emergy use, while technology innovation offset the increase of total emergy use. Policy insights suggest that industrial regions should improve their energy efficiency and optimize their economic and energy structure by applying economic instruments and capacity building efforts. - Highlights: • Emergy analysis and IPAT are combined to evaluate the sustainability of Liaoning. • Total emergy of Liaoning increased from 2002 to 2011 and then decreased in 2012. • Economic scale is the key driving force to induce higher emergy consumption. • Valuable policy insights are proposed in order to promote sustainable development.

    There are 110 million people in Sichuan Province, China. Although most of the people in cities of Sichuan use river water, which contains low levels of radon, as potable water, people in countryside and in some communities of big cities still use well water as domestic consumption. This paper reports the radon concentrations in well water investigated in four cities, i.e. Chengdu, Chongqing, Leshan and Leijiang in Sichuan Province. Of the 80 wells investigated, the radon concentrations range from 3.5 to 181.6 KBqm -3 . Of the four cities, Chongqing has the highest well water radon concentration with the average 49.6 ± 54.1 KBqm -3 and the greatest variation. The investigation in four cities showed that the radon concentrations in well water are much higher than that in tap-water. In Chongqing where there are complex geological structures, mainly granite stratum, for example, the average radon concentration in well water is 112 times higher than that in the tap-water, and even much higher than that in river water in Yangtse River, Jialing River, Jinsha River and Mingjiang River. The population in four cities is about one sixth of the total population in Sichuan Province. Because of the common use of well water and the high radon concentrations in well water in Sichuan Province, the health effect of radon in well water to the public should be stressed. (author)

    Jowett, A J

    1989-10-01

    This is part 2 of a 2-part paper discussing mainland China's 1-child policy. In part 1, Jowett argues that a national 1-child program does not exist in China. Instead, China has a series of regional policies which vary between and within provinces. Part 2 discusses these variations in childbearing policy. 1 table contrasts the developed coastal province of Liaoning and the underdeveloped interior province of Guizhou. In Liaoning, more than 75% of the women are literate, and infant mortality is less that 20/1000. In Guizhou, fewer than 33% of the women are literate, and infant mortality is over 60/1000. The per capital gross national product is 4.5 times higher in Liaoning. The birth rate is almost 10 points higher and the fertility rate almost 2.5 times greater in Guizhou than in Liaoning. The defiance of the 1-child policy is partially linked to the shift in social values taking place in mainland China. A trend toward earlier marriage and earlier childbearing has contributed to the rising birth rates in the 1980s. Unlike the outcome of the student protests in Tiananmen Square, conflict over family size has generally been resolved in favor of individual wished rather than government objectives.

    To survey the cataract surgery rate (CSR) according to the report data and its influencing factors of Jiangsu Province in 2012 so as to further improve CSR in China. Through government websites in 2012, gross domestic product (GDP) and GDP per capital of 13 cities in Jiangsu Province and 7 counties of Nantong City reported to the Ministry of Health in China were collected to calculate CSR. The relationship between GDP and CSR of Jiangsu Province and Nantong City were analyzed with Spearman's rank correlation, and the differences in the proportion of cataract surgery between government and private hospitals were analyzed by Chi-square test. CSR in Jiangsu Province in 2012 was 939 cases per million population per year. Nantong City had the highest CSR (1362 cases per million population per year) and Suqian City the lowest (129 cases per million population per year). The GDP of 13 cities in Jiangsu Province had a positive correlation with CSR (spearman r = 0.59, P = 0.03), but there was no significant correlation with GDP per capital (spearman r = 0.50, P = 0.08). No significant correlation existed between GDP, GDP per capital and CSR of 7 counties of Nantong City (spearman r = -0.04, P = 0.94; spearman r = -0.29, P = 0.53). The proportion of private hospitals of Nantong was 33.3% and surgery cases were 4557 (45.9%). The CSR of Rugao County in 2012 was 3317 cases per million population per year. Socioeconomic level may be related with CSR. Providing village cataract screening services and lowering surgical costs help to boost CSR in China.

    Homeobox protein Hox-C8 (HOXC8) is a member of Hox family. It is expressed in the dermal papilla of the skin and is thought to be associated with the hair inductive capacity of dermal papilla cells. In the present study, we isolated and characterized a full-length open reading frame of HOXC8 cDNA from the skin tissue of Liaoning cashmere goat, as well as, established a phylogenetic relationship of goat HOXC8 with that of other species. Also, we investigated the effect of methylation status of HOXC8 exon 1 at anagen secondary hair follicle on the cashmere fiber traits in Liaoning cashmere goat. The sequence analysis indicated that the obtained cDNA was 1134-bp in length containing a complete ORF of 729-bp. It encoded a peptide of 242 amino acid residues in length. The structural analysis indicated that goat HOXC8 contained a typical homeobox domain. The phylogenetic analysis revealed that Capra hircus HOXC8 had a closer genetic relationship with that of Ovis aries, followed by Bos Taurus and Bubalus bubalis. The methylation analysis suggested that the methylation degree of HOXC8 exon 1 in anagen secondary hair follicle might be involved in regulating the growth of cashmere fiber in Liaoning cashmere goat. Our results provide new evidence for understanding the molecular structural and evolutionary characteristics of HOXC8 in Liaoning cashmere goat, as well as, for further insight into the role of methylation degree of HOXC8 exon 1 regulates the growth of cashmere fiber in goat.

    Full Text Available Mosque for Muslims who living in the middle of minority neighborhood in Province of Bali not only function as a signifier for the presence a Muslims community, but also have a central role because mosque is the only gathering place for fellow Muslims. In the present, Muslims in the province of Bali is facing various challenge that cause adaptation strategies of mosque architecture for the existence of mosque in the neighborhood can be accepted by society from other faith. This preliminary study aim to knowing the adaptation strategies of mosque architecture undertaken Muslims in the province of Bali along with the factor that drive adaptation. Study conducted using qualitative-inductive method. Locus of study in the Denpasar City and Badung Regency where is the center of activity and concentration of Muslims in the province of Bali with a different background neighborhood. Object of study used a large mosque that are the central of Muslims activity. The finding this study showed that there are three types of mosque architecture adaptation strategies undertaken by Muslims in the Province of Bali are (1 external factor are responded by applying dominate elements of Balinese style architecture, (2 internal factor is awareness to applying elements of Balinese style architecture to show identity as a Muslims who appreciate local value, and (3 internal factor to applying the characteristic architectural style of the Middle East mosque is considered ideal to represent identity as Muslims.

    Full Text Available Tanjung Pinang City of the Riau Islands Province (Provinsi Kepulauan Riau is a transit area for the troubled Indonesian overseas workers from Singapore and Malaysia. The Indonesian National Board for the Placement and Protection of Indonesian Workers (Badan Nasional Penempatan dan Perlindungan Tenaga Kerja Indonesia/BNP2TKI reported that 15,105 troubled Indonesian overseas workers were deported from January to November 2014 via Tanjung Pinang City.  Previous research revealed that citizens of Tanjung Pinang City criticized the treatments given by the local government to the deported workers by reason that they were not the citizens of the Riau Islands Province, yet the local government has to provide shelters and funds prior to returning them to their home towns. The treatments for the deported workers in the transit area have also raised pros and cons among the stakeholders who are in charge of handling the deported workers. This circumstance may not occur if a special regional regulation of the Riau Islands Province has been issued to govern the troubled Indonesian overseas workers in the transit area.  Due to this vacuum of law, this research aims to establish a mechanism in handling the deported workers in the transit area by designing an integrative-progressive model which can be adopted by the stakeholders. The model is to link the legal and non- legal issues and as well as to provide the collaborative mechanisms for the stakeholders based on the approaches of the integrative and progressive legal theory.

    Teaching has been reported to be one of the most stressful occupations in the world. Few studies have been conducted to explore the effects of occupational stress on burnout among teachers in developing countries. This study aimed to explore the relationship between occupational stress and burnout among teachers in primary and secondary schools in the Liaoning Province of China. A questionnaire that assessed occupational stress comprised of Karasek's job content questionnaire (JCQ), Siegrist's effort-reward imbalance questionnaire (ERI), and burnout assessed by the Maslach Burnout Inventory-General Survey was distributed to 681 teachers in primary and secondary schools. A total of 559 effective respondents became our final study subjects. Hierarchical linear regression and logistic regression analyses were performed through the use of SPSS 17.0 to explore the association between occupational stress and burnout. A high level of emotional exhaustion was significantly associated with high extrinsic effort, high overcommitment, low skill discretion, and high job demand. A high level of cynicism was associated with low reward, low skill discretion, high overcommitment, and low supervisor support. The low level of professional efficacy was associated with low coworker support, low reward, low skill discretion, and high job demand. Compared to the JCQ, the ERI was more likely to explain the burnout of teachers in our study. Occupational stress proved to be associated with dimensions of burnout among Chinese teachers. It is important for administrators of primary and middle schools to note that strategies to decrease teachers' occupational stress seem to be crucial to enhance physical and mental health of teachers in China.

    We describe a new ornithuromorph bird species, Gansus zheni from the Lower Cretaceous lacustrine deposits of the Jiufotang Formation (Jehol Group), Liaoning Province, China. A cladistic analysis resolves Gansus zheni as the sister taxon of the roughly contemporaneous Gansus yumenensis (Xiagou Formation, Gansu Province), and together as the most immediate outgroup to Ornithurae. Gansus zheni is the most advanced bird known today for the Jehol Biota. Its discovery provides the best-documented case of inter-basinal correlations (Jehol and Changma basins of Liaoning and Gansu provinces, respectively) using low-taxonomic clades of fossil birds. The existence of close relatives of Ornithurae in deposits formed at about 120 million years ago helps to mitigate the long-standing controversy between molecular and paleontological evidence for the temporal divergence of modern birds (Neornithes).

    Full Text Available Based on the surface meteorological data of Jiangsu Province during 1980–2012, the climatic characteristics and the trends of haze were analyzed. The results indicated that during 1980–2012 haze days increased; in particular, severe and moderate haze days significantly increased. In the northern and coastal cities of Jiangsu Province China, haze days showed a significant increase. Haze often appeared in fall and winter and rarely in summer in the study area. It also occurred more often inland, and less along the coast. Haze occurred more often in June due to straw burning in the harvest time. The haze day increased during the 1990s over southern and southwestern Jiangsu Province; in central and northern Jiangsu, haze day increased after 2000. The continuous, regional, and regional continuous haze days all showed increasing trends. As the urban area expanded each year, industrial emissions, coal consumption, and car ownership increased accordingly, resulting in regional temperature increase and relative humidity decrease, which formed the urban heat island and dry island effects. Hence, haze formation and maintenance conditions became more favorable for more haze days, which led to the increase of haze days, and the significant increases of continuous, regional, and regional continuous haze days.

    Tetracyclines (TCs), a class of antibiotics with a broad spectrum, are the most frequently used antibiotics in animal production. The major concern is that the widespread use of the antibiotics may lead to the emergence of new strains of bacteria that are resistant to these antibiotics. The objective of this study was to determine the residual levels of oxytetracycline and tetracycline in 80 animal manure samples that were collected from the livestock and poultry feedlots in Khuzestan Province. The residual levels of the antibiotics in the samples were extracted by using solid-phase extraction (SPE) method and subsequently were measured by liquid chromatography. Recoveries from the spiked poultry manure samples ranged from 65 to 113% for tetracycline and 86 to 132% for oxytetracycline. Relative standard deviations of the recoveries were less than 5.7% within the same day. Method detection limit (MDL) measured for oxytetracycline and tetracycline in the manure were 0.011 and 0.01 mg/kg, respectively. Analysis of the collected 50 chickens and 30 cow manure samples showed that the highest concentration of tetracycline was related to Behbahan City (5.36 mg/kg) and the lowest concentration was detected for Ramhormoz (0.05 mg/kg). The highest and lowest concentrations of oxytetracycline were respectively observed for Behbahan (13.77 mg/kg) and Ramhormoz (0.047 mg/kg). Based on the results, in chicken manure, there was significant statistical difference between the residual TC concentrations among five cities (p(value) oxytetracyclin (OTC) residual concentrations among five cities (p(value) > 0.05).

    Yanshan-Liaoning area is located in the east part of the northern margin of North-China platform. It is a famous metallogenic region of Mesozoic volcanic hydrothermal type U-Au-polymetallic deposits in the country. The metallogenesis is controlled by a united Late Mesozoic continental taphrogenic volcano-magmatic activity. The metallogenic epochs are concentrated in Late Jurassic-Early Cretaceous periods. The metallogenic media are moderate and moderate-low temperature volcanic hydrothermal solutions originated from the mixing of volcano-magmatic water, metamorphic water and atmospheric water. The ore-forming materials are mainly derived from enrichment type upper mantle and lower crust. (8 refs., 5 figs.)

    Based on the monitoring data for years in Shandong Province, current situation of acid rain in every city was assessed, and the temporal distribution of the dry, wet and total sulfur deposition in Jinan and Qingdao were studied. The results showed that Qingdao which had the largest precipitation acidity was the single city whose annul average precipitation pH was below 5. 60. The precipitation acidities in the main cities of Shandong Province were in a descent tendency. The total sulfur desposition in Jinan and Qingdao was basically stable or in a descent tendency, but also reached 10 t/(km(2)x a) or so. Among the total sulfur deposition flux, the dry deposition of sulfur had the greater contribution, and the contribution of SO2 dry deposition was higher than that of SO42- dry deposition. By analyzing the relation between the precipitation acidity and the SO2 discharge intensity, soil acidity and meteorological condition, the impact factors of acid precipitation in the cities of Shandong Province were revealed.

    Scenario analysis was used to study the environmental burden in a coastal city of Zhejiang province under different patterns of economic development. The aim of this research is to propose advices on decision making by illustrating how to make emissions reduced by transforming the pattern of economic development in a developed coastal area, which had acquired the level of 70 000 yuan GDP per cap. At first, 18 heavy pollution industries were screened out, by referencing total emissions of chemical oxygen demand, ammonia-nitrogen, sulfur dioxide, and nitrogen oxide. Then, a model of scenario analysis and the back-up calculation program were designed to study the sustainable development of the heavy pollution industries. With 2008 and 2015 as the reference year and the target year respectively, emissions of four pollutants mentioned above in the 18 heavy pollution industries in the city were analyzed under six scenarios. The total emissions of 4 pollutants should be reduced to an expectant degree, which is set as the constraint prerequisite of the scenario analysis. At last, some suggestions for decision-making are put forward, which include maintaining a moderate increase rate of GDP around 7%, strengthening the adjustment of economic structure, controlling the increasing rate of industrial added value of the industries with heavy pollution, optimizing the structure of industries with heavy pollution, decreasing the intensity of waste emission by implementing cleaner production to reduce emission produce at the source, and strengthening regulations on the operation of waste treatment plants to further promote the efficiency of waste treatment. Only by implementing such measures mentioned above, can the total emissions of chemical oxygen demand, ammonia-nitrogen, sulfur dioxide, and nitrogen oxide of the 18 industries with heavy pollution in the city be reduced by a 10%, 10%, 5%, and 15% respectively based on the reference year.

    Aflatoxin M(1) (AFM(1)) is the metabolite of aflatoxin B1 (AFB(1)) and is found in milk when lactating animals are fed with contaminated feedstuff. The presence of AFM(1) in milk, pose a major risk for humans especially kids as it can have immunosuppressive, mutagenic, teratogenic and carcinogenic effects. The present study is aimed to investigate the occurrence of AFM(1) in subsidized pasteurized milk in Babol, Mazandaran Province, Iran. Some 72 pasteurized milk packages were collected from supermarkets in various districts of city during January to March 2006. Milk samples were centrifuged and amounts of 100 μl of skimmed milk were tested for AFM(1) contamination by competitive ELISA. All the samples (100%) exhibited contamination with AFM(1). The contamination levels means in January, February, and March were 227.85, 229.64, and 233.1ng/l, respectively. The amount of AFM(1) in all the samples were above 50ng/l, the threshold set by the European community regulations. Monitoring of AFM(1) level should be part of quality control procedures in dairy factories, particularly the ones providing infant's milk. Production of safer and healthier milk and other dairy products with minimum AFM(1) level can be achieved by adopting prophylactic measures including control of humidity and water content of feedstuff, which favors mould production.

  6. From smart city to smart destination. The case of three Canadian cities

    2018-03-01

    Full Text Available Several cities around the world are self-proclaimed "smart" by integrating, in varying degrees, new technologies in the different spheres of the city. Nevertheless, despite this effervescence around the smart city, the concept requires more conceptualization from the researchers. This is even more important when it comes time to distinguishing between smart city and smart destination. The relationship between these two concepts is blurred and the transition from the smart city to the smart destination is not automatic. This situation is explained by the fact that the intrinsic characteristics of their respective target populations, being the citizens and the tourists, are different. This article compares three Canadian cities in the province of Quebec with the aim of demonstrating that the realization of a smart destination project requires the adaptation of governance structure and the involvement of all the stakeholders and more particularly in tourism.

    Serui City in Papua Province has many unique characters and must be maintained for the sake of the continuity of its identity. However, this city still lacks the facility and depend on other areas. Accordingly, it becomes vulnerable. The wholeness of the city is not just by having strong character but also having strength regarding vitality. The loss of it can affect the character and even eliminate it. Cities and people have many similarities regarding character and vitality. Therefore, there is a chance to solve the problems in the city using the similar approach to treat the human. We called city personification methods as problem-solving to the city. It means that we treat the city as a human being so that the problem can be solved as the human’s treatment. The personification of this city is conducted because of the many treatments that have proven effective in humans and may also be powerful to manifest in city. The personification makes the design will only focus on the particular networks and not on the whole “body,” remain in the hope for strengthening (maintain and improve) the quality of wholeness (character and vitality) city which in this case is Serui.

    Full Text Available Sistan and Baluchestan Province spans five degrees latitude, with variations in natural phenomena, with cultural and historical resources and beautiful beaches in the south that have a great potential in attracting tourists. To investigate the relationship between climate and tourism, the climate index has been developed so that data are presented showing the individuals’ reactions to climate. The current study chose the tourist major cities of Iran and meteorological data was used to calculate the 20-year period up to 2012. In order to calculate the three climate indices (Predict Mean Vote - PMV, the Physiological Equivalent Temperature - PET and the Standard Effective Temperature - SET, RayMan software was used. These indices were then discussed and the spatial distribution of climatic comfort was represented in GIS environment. The most important national, religious, historical, and natural places in the province were presented and the climate calendar of tourism was identified. The results showed that tourism is concentrated in two periods, hot and cold. The cold period in southern cities such as Chabahar, Konarak and Sarbaz makes them tourist destinations, while the cities of Zahedan, Khash, Zabol, located at higher latitudes, are chosen tourist destination in spring and autumn. Summer has the highest thermal stress in the province.

    Full Text Available This research presents an optimum framework for hardboard industry location selection in Mazandaran Province. Considering the existence of only two depreciated hardboard plants with very old technology in Iran, the establishment of new plants are vital. To materialize this goal, Mazandaran province enjoys priorities to other provinces based on its resources of raw lignocellulosic materials required for wood and paper industries. The model presented in this article uses AHP benefit/cost ratios. The results indicate that the criterion of ‘material and production’ with a weight of 0.327 and the sub-criterion of ‘reliability of supply’ with a weight of 0.146 have the highest priorities, and the city of Sari is the best alternative.

    Water footprint (WF) methodology is essential for quantifying total water consumption of crop production and making efficient water management policies. This study calculated the green, blue, grey and total WFs of maize production in Northeast China from 1998 to 2012 and compared the values of the provinces. This study also analyzed the spatial variation and structure characteristics of the WFs at the prefecture level. The annual average WF of maize production was 1029 m(3) per ton, which was 51% green, 21% blue and 28% grey. The WF of maize production was highest in Liaoning Province, moderate in Heilongjiang Province and lowest in Jilin Province. The spatial differences of the WFs calculated for the 36 major maize production prefectures were significant in Northeast China. There was a moderate positive spatial autocorrelation among prefectures that had similar WFs. Local indicator of spatial autocorrelation index (LISA) analysis identified prefectures with higher WFs in the southeast region of Liaoning Province and the southwest region of Heilongjiang Province and prefectures with lower WFs in the middle of Jilin Province. Spatial differences in the WF of maize production were caused mainly by variations in climate conditions, soil quality, irrigation facilities and maize yield. The spatial distribution of WFs can help provide a scientific basis for optimizing maize production distribution and then formulate strategies to reduce the WF of maize production. © 2015 Society of Chemical Industry.

    Objective To know the contamination status of Giardia lamblia and Cryptosporidium in drinking water of Jiangsu Province, so as to provide the evidence for producing hygiene and safety drinking water. Methods A total of 28 water plants of 13 cities in Jiangsu Province were selected, and the source water (10 L), chlorinated water (100 L) and tap water (100 L) were collected separately in each site. The water samples were then treated by filtration, washing, centrifuging concentration, immune magnetic separation, and immunofluorescent assay, to detect the numbers of Giardia cysts and Cryptosporidium oocysts. Results Totally 84 samples from 13 cities were collected, including 28 source water, 28 chlorinated water and 28 tap water samples. Among the chlorinated water and tap water samples, no Giardia cysts and Cryptosporidium oocysts were found. However, Giardia cysts were detected in 3 (10.71%, 3/28) source water samples (Yancheng, Lianyungang, Changzhou cities), with the density of 1 cyst/10 L of all. Cryptosporidium oocysts were also detected in 3 (10.71%, 3/28) source water samples (Nanjing, Zhenjiang, Yangzhou cities), with the density of 1 oocyst/10 L of all. Conclusions The source water in partial areas of Jiangsu Province has been contaminated by Giardia and Cryptosporidium . To ensure the safety of drinking, the regulation of source water and surveillance of drinking water should be strengthened.

    Full Text Available Objective: In Zhejiang Province, there are several highly developed cities near the coast and several relatively under-developed mountain areas. Analysis of the composition of bacteria isolated from patients as well as their antibiotic resistance profile from various areas of this province, and tracing of such data year-by-year, will help to delineate the bacterial resistance profile of these areas and to understand how the stage of socio-economical development impacts on the composition of clinical micro-flora and their resistance profile. Methods: In order to investigate variation in resistance rates and isolation rates of Enterobacteriaceae, from 2000 to 2009 in Zhejiang Province, China, Enterobacteriaceae isolated from 15 hospitals located in different regions of the province were surveyed. Results: The total numbers of the Enterobacteriaceae isolated increased more than 20-fold from 2000 to 2009. Among the Enterobacteriaceae, Escherichia coli and Klebsiella pneumoniae were the dominant isolates. The percentage of E. coli and K. pneumoniae that produced detectable extended-spectrum ?-lactamases (ESBLs increased from 2000 to 2007, and then declined slightly in 2008 and 2009. The percentages of K. pneumoniae and E. coli that were resistant to ceftazidime increased sharply from 2000 to 2009. There were remarkable increases in the carbapenem resistant rates during the decade, but they were much higher for the isolates from the developed cities than from the rural areas. In 2002, carbapenem-resistant E. coli was first found in Hangzhou, one of the highly developed cities in Zhejiang Province. By 2009, carbapenem-resistant bacteria were found for all species of Enterobacteriaceae surveyed in almost all areas of the province, although they were more frequently identified in developed areas than in rural areas. Conclusion: Much restrictive actions have to be taken in terms of rational use of antibiotics and nosocomial control to prevent the further

    Background Acanthamoeba spp. are free-living amoebae commonly found in the environmental sources such as water, soil, and air. This ubiquitous amoeba is the causative agent of amoebic keratitis (AK). The objective of the present study was to investigate the presence of Acanthamoeba spp. in water and soil sources in Ahvaz City, Khuzestan Province, southern Iran. Methods In general, 110 samples of water and soil were taken from different localities of Ahvaz including agricultural canals, rivers, and swimming pools. Filtration and cultivation were carried out on non-nutrient agar medium (NNA). Axenic cultivation was performed for all of positive isolates. PCR analysis was conducted on positive samples. Sequencing was done for 15 PCR products. Genotypes were identified by Blast search and homology analysis. Results Acanthamoeba spp. was found in 43 (71.6%) of samples of water and 13 (26%) soil samples. Genotyping of 15 samples proved that Acanthamoeba belonged to T4 (86.6%), T2 (6.6%), and T5 (6.6%) genotypes. Conclusion TYI-S-33 medium could be better than PYG medium for Acanthamoeba axenic culture. PMID:23323088

    To determine the epidemiological characteristics of fatal traffic accidents in Fars province, Iran. This cross-sectional study included 3642 traffic accident deaths in Fars province, Iran between November 2009 and November 2011. The data source was the Fars Forensic Medicine Registry, which covers the entire province. According to Iranian law, all deaths resulting from injuries or accidents must be investigated to determine the exact cause of death by autopsy. All such deaths are referred to forensic medicine centres in each city, and all data are sent to the main centre in Shiraz, the capital city of Fars province. Males accounted for 78.3% of the decedents (sex ratio of almost 3.6:1), and the mean ± standard deviation age of all decedents was 32.2 ± 20.3 years. Autopsy reports indicated that head trauma was the most common cause of death. Most collisions were vehicle-vehicle crashes (52.3%), with cars and motorcycles being the most prevalent modes of transport (39.6% and 24.6%, respectively). Fatal accidents were most common during the summer. Most fatal injuries (61.4%) occurred on outer-city roads and 27.4% occurred on inner-city roads. Significant associations were found between decedent's status (car driver, motorcycle driver or passenger, pedestrian or passenger) and interval between injury and death, light conditions at the scene of the accident, place of death, site of injury and cause of death. Although the clinical management of trauma patients has improved in Iran, coordination between trauma system organizations is required to decrease the burden of injuries.

    Full Text Available The relationship between transportation infrastructure investment and regional economic growth has been the focus of domestic and foreign academic research. Using the models of coupling degree and coupling coordination degree, this paper calculated the coupling degree and coupling coordination degree between the comprehensive level of transportation infrastructure investment and economic development in Hubei province and its 17 cities, and analyzed its temporal and spatial characteristics. The result showed that, from 2001 to 2013, the coupling and coupling coordination between transportation infrastructure investment and economic development in Hubei province were on a steady rise in the time sequence characteristics. It experienced the upgrade from the uncoordinated – nearly uncoordinated – barely coordinated – intermediately coordinated stages. In the year of 2013, the coupling and coupling coordination of transportation infrastructure investment and economic development in the 17 prefecture-level cities of Hubei Province showed a very uneven spatial difference. Good coordination, primary coordination, barely coordinate, and barely in-coordination are distributed in the province. The average coordination degree of the 17 prefecture-level cities in Hubei is relatively low, and there is a negative tend to expand the difference. This study has confirmed the relationship between transportation infrastructure investment and the economic development to be in an interactive coupling and coordination, but in different regions and different stages, the degree of coordination has obvious spatial and temporal differences.

    Full Text Available Anemia is the main micronutrient deficiency problem among adolescent girls in Indonesia. Anemia due to iron deficiency often coexists with zinc deficiency. Both iron deficiency anemia and zinc deficiency can increase the risk of obstetric complications among pregnant women i.e. bleeding during labor and post-partum hemorrhage. Iron-folate supplementation among pregnant women had been conducting since long time ago throughout this country; however, effort to improve the nutritional status particularly among adolescent girls prior to pregnancy is still lack behind. Iron and zinc have antagonistic interaction. Therefore it was challenging to alleviate anemia problem among adolescent girls with appropriate ratio of iron-zinc supplementation, and will give a benefit to improve their nutritional status. This study was aimed to investigate the different ratios of ironzinc supplementation on reducing the prevalence of anemia as improving the nutritional status of adolescent school girls.A female elementary school students age 10-12 years old (n= 137 were screened in rural area of Kupang City, East Timor Province. Subjects were assigned randomly to one of the three groups for daily iron-zinc supplementation for 12 weeks; Group 1 (iron; 60 mg/day, Group 2 (iron and zinc; 30 mg and 15 mg/day, Group 3 (iron and zinc; 60 mg and 15 mg/day. Hemoglobin concentration was measured by cyanmethemoglobin method (Hemocue to determine the prevalence of anemia (Hb level < 120 g/L, while anthropometric assessment was conducted for measuring weight and height to determine the nutritional status. General characteristics was assessed through interview. At base line, 29.1% of subjects suffered from anemia and in general, the prevalence was reduced to around 13.1% after they took iron supplements with or without zinc. Hemoglobin concentration was significantly increased among all subjects euther suffered from anemia or not. The result of this study showed that subject who

    Background In China, a growing number of adolescents have experienced traumatic events that have resulted in PTSD (post-traumatic stress disorder). Post-traumatic symptoms are common psychological problems in adolescents who have experienced traumatic events. However, existing studies tend to focus on the factors influencing PTSD, such as the response styles and social support, and studies on the relationships between parenting style, resilience and post-traumatic symptoms are still rare. Objectives To analyze the relationships between parenting style, resilience and post-traumatic symptoms among adolescents in China. Methods A cross-sectional survey was conducted from June to December 2013 in the Liaoning Province, China. N = 5765 adolescents (aged 12 to 18 years old) were ultimately chosen to participate. The Chinese version of the Essen Trauma Inventory for Kids and Juveniles (ETI-KJ), a modified version of the Parental Authority Questionnaire, and the Chinese Resilience Scale were used to estimate the post-traumatic symptoms, parenting style, and resilience, respectively. Pearson’s correlations, multiple linear regression analyses and structural equation modeling (SEM) were applied to analyze the data. Results Of the adolescents, 39.76% (N = 2292) had been exposed to traumatic events during their lives. The prevalence of probable PTSD at the time of the interview (one-month-prevalence) was 12.65%. Parenting style and resilience were significantly associated with post-traumatic symptoms.

Post-traumatic symptoms are common psychological problems in adolescents who have experienced traumatic events. However, existing studies tend to focus on the factors influencing PTSD, such as the response styles and social support, and studies on the relationships between parenting style, resilience and post-traumatic symptoms are still rare. To analyze the relationships between parenting style, resilience and post-traumatic symptoms among adolescents in China. A cross-sectional survey was conducted from June to December 2013 in the Liaoning Province, China. N = 5765 adolescents (aged 12 to 18 years old) were ultimately chosen to participate. The Chinese version of the Essen Trauma Inventory for Kids and Juveniles (ETI-KJ), a modified version of the Parental Authority Questionnaire, and the Chinese Resilience Scale were used to estimate the post-traumatic symptoms, parenting style, and resilience, respectively. Pearson's correlations, multiple linear regression analyses and structural equation modeling (SEM) were applied to analyze the data. Of the adolescents, 39.76% (N = 2292) had been exposed to traumatic events during their lives. The prevalence of probable PTSD at the time of the interview (one-month-prevalence) was 12.65%. Parenting style and resilience were significantly associated with post-traumatic symptoms. According to the SEM, parenting style had a significant direct effect on resilience (0.70, Pparenting style had a significant indirect effect (-0.43×0.70 = -0.30. PParenting style and resilience have significant effects on adolescents' post-traumatic symptoms. Schools and social-related departments could share knowledge on the impact of parenting style with parents enabling them to improve their own parenting style and their children's resilience and ability to respond effectively to traumatic events.

    According to the World Health Organization (WHO) reports, Iran is located in the global fluoride belts, so that is why carrying out extended research on this contaminant anion in water supplies must be considered. Due to the various industries in the Ardakan city, this region is severely suffering from fluoride contamination. This study was designed to investigate the fluoride concentration and its distribution pattern as well as related health risk assessment in groundwater resources of 28 villages of the Ardakan city in Yazd province using SPADNS method according to standard instructions. Our results show that, the average concentration of fluoride was 2.92 mg/l (range: 0.9-6 mg/l), also in half of the villages, the concentration range of this element was over than standard level (1.5 mg/l) given by WHO rules. In addition, risk assessment results showed that HQ value is higher than 1 in 46.4% of samples of groundwater resources in age groups of infants, children, teenagers and adults. Therefore, it is necessary to take measures to reduce fluoride concentration in drinking water in order to control resultant fluorosis. Actions should be implemented to enhance monitoring of fluoride levels to avoid the potential risk of high Fluoride concentration.

    Concentrations of 13 perfluoroalkyl substances (PFASs) were quantified in 79 surface soil samples from 17 coastal cities in three provinces and one municipality along the Bohai and Yellow Seas. The ∑PFASs concentrations ranged from less than limitation of quantification (LOQ) to 13.97 ng/g dry weight (dw), with a mean of 0.98 ng/g dw. The highest concentration was observed along the Xiaoqing River from Shandong province, followed by that from the Haihe River in Tianjin (10.62 ng/g dw). Among four regions, ∑PFASs concentrations decreased in the order of Tianjin, Shandong, Liaoning and Hebei, which was consistent with levels of urbanization. Fluorine chemical industries allocated in Shandong and Liaoning played important roles in terms of point emission and contamination of PFASs, dominated by perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). Intensive anthropogenic activities involved in urbanization possibly resulted in increasing releases of PFASs from industrial and domestic sources. - Highlights: • PFASs were detected in the soil of rapidly developing coastal regions in China. • PFAS concentrations ranged from LOQ to 13.97 ng/g dw, with a mean of 0.98 ng/g dw. • Higher concentrations of PFASs correspond to higher levels of urbanization. • Existence of fluorine industry induced PFAS pollutions dominated by PFOA and PFOS. • Intensive urbanization caused increasing emission of industrial and domestic PFASs. - Among urban, suburban and rural areas in the coasts, soils from urban area showed high degrees of PFASs contamination with the existence of industrial emissions dominated by PFOA and PFOS

    Full Text Available The term “eco-city,” and similar concepts such as “green” and “sustainable” cities, has evolved overtime concurrent to the development of the understanding of social change and mankind’s impact on environmental and economic health. With the advent of climate change impacts, modern economies developed the green city policy to create sustainable urban development, low emission, and environmentally friendly cities. In South Africa municipalities, including Buffalo City Metropolitan Municipality (BCMM have been tasked to and implement the green city policy. However, BCMM is yet to develop the green city policy that clearly articulate how the municipality will combat climate change and reduce its Green House Gases (GHG emissions in its spatial planning designs. Against this background, this article reviews and analyses green policy landscape in Metropolitan Municipalities. It is envisaged that the research will provide the basis for the development of a comprehensive green policy strategies and programmes for the local transition to action in Buffalo City Metropolitan Municipality, in the Eastern Cape Province.

    Full Text Available BACKGROUND: The objectives of the survey were to identify the level of influenza vaccination coverage in China in three influenza seasons 2009/10 to 2011/12, and to find out potential predictors for seasonal influenza vaccination. METHODS: In September and October 2011, representative urban household telephone surveys were conducted in five provinces in China with a response rate of 6%. Four target groups were defined for analysis: 1 children ≤ 5 years old; 2 elderly persons aged ≥ 60 years old; 3 health care workers (persons working in the medical field and 4 chronically ill persons. RESULTS: The overall mean vaccination rate was 9.0%. Among the four target groups, the rate of vaccination of children aged ≤ 5 years old (mean = 26% was highest and the rate of elderly people aged ≥ 60 years old (mean = 7.4% was the lowest, while the rates of persons who suffer from a chronic illness (mean = 9.4% and health care workers (9.5% were similar. A subsidy for influenza vaccination, age group, health care workers, suffering from a chronic illness and living in Eastern China were independent significant predictors for influenza vaccination. CONCLUSIONS: The seasonal influenza vaccination coverage rates among urban populations in selected cities and provinces in China were far below previously reported rates in developed countries. Influenza vaccination coverage rates differed widely between different target groups and provinces in China. Subsidy policy might have a positive effect on influenza vaccination rate, but further cost-effectiveness studies, as well as the vaccination rate associated factors studies are still needed to inform strategies to increase coverage.

    Full Text Available The characteristics of equipping the Subcarpathian province cities with water supply infrastructure was made on the basis of data collected from the Provincial Office, Statistical Office, reports submitted by water companies regarding the functioning of water supply infrastructure and literature data. The indicators characterizing water supply infrastructure were determined for the years 1995-2014. In the paper the indicators of equipping cities with water supply systems were presented. Also water consumption and changes in the length of the water supply network in the cities of the Subcarpathian Province were examined. The analysis shows that the water consumption for the years 1995-2014 decreased by almost 6 m3∙year-1 per capita. The reason for such situation was the increasing price of water and the ecological awareness of the inhabitants of the Subcarpathian region. In the last year of the analysis the water supply system in urban areas of the Subcarpathian province was used by 95% of the population and, for comparison, in rural areas by 77% of the population. In the paper also changes in prices for water in the Subcarpathian region were shown, on the basis of data from the water tariffs in individual water companies. The important element of urban development is the technical infrastructure which reduces the investment costs. The determined indicators of equipping cities with water supply systems show an upward trend in the development of technical infrastructure. Based on the operational data from the water companies the failure rates in selected water supply networks were determined.

    The recent discovery of small paravian theropod dinosaurs with well-preserved feathers in the Middle-Late Jurassic Tiaojishan Formation of Liaoning Province (northeastern China) has challenged the pivotal position of Archaeopteryx, regarded from its discovery to be the most basal bird. Removing Archaeopteryx from the base of Avialae to nest within Deinonychosauria implies that typical bird flight, powered by the forelimbs only, either evolved at least twice, or was subsequently lost or modified in some deinonychosaurians. Here we describe the complete skeleton of a new paravian from the Tiaojishan Formation of Liaoning Province, China. Including this new taxon in a comprehensive phylogenetic analysis for basal Paraves does the following: (1) it recovers it as the basal-most avialan; (2) it confirms the avialan status of Archaeopteryx; (3) it places Troodontidae as the sister-group to Avialae; (4) it supports a single origin of powered flight within Paraves; and (5) it implies that the early diversification of Paraves and Avialae took place in the Middle-Late Jurassic period.

    Taking 2000-2003’s data of foreign exchange income and the number of inbound tourism from as the sample, we studied the inbound tourism flow and the change of the Liquiity and the synergy degree in these cities. The flow of inbound tourism and the Liquiity in Henan province presented the characteristics of opposite change. In flow, it presents the steady uptrend, there were 3 general forms: gradually reducing, gradually rising and cross rolling type. In Liquiity, its types of high-quality and low-quality flows are basic equivalence, presents the staggered change state. Inbound tourism flow and the evolution of the Liquiity in Henan province can be divided into 3 stages, 2003 and 2008 is a node of its division. The evolution of the inbound tourism flow and Liquiity collaborative structure show that the complex conditions, especially the evolution of the synchronous 2-high type cities and synchronous middle type cities show a trend of decline. The number of later one appears to a change trend of increasing first and then, steady. The number of deviation cities is volatility. The reverse deviation cities are the most, which present a trend of decreasing at first, then coming steady.

    Full Text Available China is an agriculturally-producing country and the safety of its vegetables will have an extensive attention at home and abroad. Recently, contamination of soils and vegetables caused by mining activities is of great social concern because of the potential risk to human health, especially to the residents whom live near metal or metalloid mines. In this study, 18 topsoil and 141 vegetable samples were collected from the contaminated areas in Daye City Hubei Province, China and the concentrations of copper (Cu, zinc (Zn, arsenic (As, cadmium (Cd and lead (Pb were analyzed. A self-designed questionnaire was assigned to obtain the exposure scenario and the USEPA health risk assessment model was adopted to assess two type of risks (non-carcinogenic risks and carcinogenic risks of vegetables to humans. The results showed that the average contents of metal(loids in soils exceeded the background value of Daye City. The average contents of metal(loids, especially As, Cd, Pb, in three kinds of vegetables were significantly higher than the permissible values based on Chinese national standard. Leafy vegetables had relatively higher concentrations and the transfer factors of As (0.015, Cd (0.080 and Pb (0.003 were comparable to leguminous and fruit vegetables. Leguminous vegetables had relatively higher concentrations and transfer factors of Cu (0.032 and Zn (0.094 than leafy and fruit vegetables. The transfer factors from soil to plants follows a decreasing order as Cd (0.068, Zn (0.047 > Cu (0.023 > As (0.006, Pb (0.002.

    Some of the local government in Indonesia claimed they already created a smart city. Mostly the claim based of IT utilization for their governance. In general, a smart city definition is to describe a developed urban area that creates sustainable economic development and high quality of life by excelling in multiple key; economy, mobility, environment, people, living, and government. For public services, the law guarantees good governance by setting the standard for e-government implicitly including for local government or a city. Based on the arguments, this research tries to test the condition of e-government of the Indonesian city in 34 provinces. The purpose is to map e-government condition by measuring indicators of smart government, which are: transparent governance and open data for the public. This research is departing from public information disclosure law and to correspond with the existence law. By examining government transparency, the output of the research can be used to measure the effectiveness of public information disclosure law and to determine the condition of e-government in local government in which as part of a smart city.

    To explore a new mode of malaria elimination through the application of digital earth system in malaria epidemic management and surveillance. While we investigated the malaria cases and deal with the epidemic areas in Jiangsu Province in 2011, we used JISIBAO UniStrong G330 GIS data acquisition unit (GPS) to collect the latitude and longitude of the cases located, and then established a landmark library about early-warning areas and an image management system by using Google Earth Free 6.2 and its image processing software. A total of 374 malaria cases were reported in Jiangsu Province in 2011. Among them, there were 13 local vivax malaria cases, 11 imported vivax malaria cases from other provinces, 20 abroad imported vivax malaria cases, 309 abroad imported falciparum malaria cases, 7 abroad imported quartan malaria cases (Plasmodium malaria infection), and 14 abroad imported ovale malaria cases (P. ovale infection). Through the analysis of Google Earth Mapping system, these malaria cases showed a certain degree of aggregation except the abroad imported quartan malaria cases which were highly sporadic. The local vivax malaria cases mainly concentrated in Sihong County, the imported vivax malaria cases from other provinces mainly concentrated in Suzhou City and Wuxi City, the abroad imported vivax malaria cases concentrated in Nanjing City, the abroad imported falciparum malaria cases clustered in the middle parts of Jiangsu Province, and the abroad imported ovale malaria cases clustered in Liyang City. The operation of Google Earth Free 6.2 is simple, convenient and quick, which could help the public health authority to make the decision of malaria prevention and control, including the use of funds and other health resources.

Today that the idea of smart city draws the attention of urban planners and policy makers and, at the same time, global competitiveness is considered essential for the success of a city, the paper aims to investigate the relationship between the concept of smart city and that of competitive city, identifying common characteristics and differences and answer the question: is “smartness” a new concept for urban studies? The analysis has been conducted in the Italian context, comparing the competitive structure of Italian provinces with their performance as smart cities. To rank Italian provinces because of their level of competitiveness, a previous ranking, carried out in 1995, has been updated with the most recent data available and the new hierarchy, thus obtained, has been compared with that of Italian smartest cities proposed by Forum PA.  The benchmarking shows that smartness and competitiveness are strictly connected: today, a city needs to improve its smart quotient in order to be more attractive and so more competitive, in fact, the efficiency and livability of cities, sought by potential citizens, can be improved by using ICTs, as supported by the advocates of smart cities, and represent a strategic factor for gaining a competitive advantage.

    Full Text Available Together, the regional economy, tourism industry, and ecological environment form mutually interactive and interdependent relationships. Therefore, a better understanding of their evolutionary relationships could help reveal the spatial-temporal evolution patterns of their coordinated development and promote a successful implementation of strategies for regional sustainable development. By choosing the 14 cities (12 cities and 2 city-level prefectures in Gansu Province as cases, this study establishes the respective evaluation indices for assessing the coordinated developmental level of the tourism system. With a combination of varying quantitative methods including order parameter analysis, fuzzy membership classification, regression analysis and gray correlation analysis, measurement models for assessing the coordinated developmental level and analyzing the associated spatial-temporal evolution patterns are established between 2000 and 2016. The conclusions are as follows. Between 2000 and 2016, the development of the regional economy, tourism industry, and ecological environment mutually reinforced one another in Gansu Province. Overall, the coordinated developmental level kept gradually improving over time. However, the development of the ecological environment lagged behind that of the tourism industry and economic growth, and synchronous and coordinated development among these three subsystems was not achieved. The overall level of coordination among 14 cities was also gradually improved, as manifested by the good level of coordinated development. However, spatial differences still existed.

    As a common source of environmental noise in China and many developing countries worldwide, construction work provokes many complaints and deterioration in acoustic climate quality. This paper describes research to obtain an improved understanding of people's community response to, and evaluation of, construction noise in three central cities of Zhejiang province, China. This involved carrying out a social survey using standard questionnaires developed by the International Commission on Biological Effects of Noise (ICBEN). A dose-response relationship model is established using a quadratic polynomial regression analysis based on construction noise exposure measurements from 40 construction sites in Hangzhou, Ningbo and Wenzhou. The results of the study indicate that the majority of people have a negative attitude to construction noise; the noise ranges between 60 dB and 80 dB (compared with 50 dB-70 dB traffic noise in Tianjin), with the percentage of highly annoyed people affected increasing from 15%-20% to 30%-40% over the range. There also different levels of annoyance depending on the time of day, and the location and activities of those affected. Other cultural differences are also apparent both between Ningbo/Wenzhou and the more urbane citizens of Hangzhou, and the Chinese people and their more noise-tolerant EU and Vietnam counterparts. The findings of this study provide a new perspective for the study of construction noise that can help local governments have an improved understanding of how residents react to construction noise for the purpose of selecting construction noise-mitigation projects and introducing construction noise-control regulations.

    Full Text Available Various socio-cultural and economic factors change the lifestyle of the people due to the changes of villages into cities. Lifestyle preferences of the people are demonstrated in leisure activities, clothing, nutrition, body management, architecture and interior design of houses. This study is aimed to examine social, cultural and economic factors that may have an impact on the lifestyle of the residents of the villages that have been converted into cities in the Khorasan Razavi Province, namely Khaf and Roshtkhar counties. According to available information between the years 2002 -2004, three suburbs called Nashtifan, Salami and Jangal were converted into cities. Theoretical research based on the theories of Ibn-Khaldun, Weber, Veblen, Simmel, Bourdieu, Giddens and Cheney have been developed. The research method was based on a survey, and a questionnaire was developed to collect data. The results show that more changes in the lifestyles of the people in the cities Salami and Nashtifan were caused by cultural factors and those in the Jangal have been caused by economic factors. Also the results show that there is a significant relationship between social participation, political and administrative organizations, ways and means of communications, individualism, identity and relationships, indirect and secondary classes as factors of social, cultural and educational facilities, wasteful  consumption and cultural capital as cultural factors, consumerism, shopping, tendency towards speculative interests, fading support of joint economic prosperity as economic factors and lifestyle.

    Population growth has an implication on increasing demand for land. The demand for built-up area is filled by land conversion, mostly from agricultural land. On the other hand, population growth requires an increase in food production as well as land for agriculture. Conversion of agricultural land can threaten the availability and food security. The purpose of this study is to identify the spatial pattern of changes in agricultural land in West Java Province as input to improve food security condition in this province. Descriptive statistics and spatial analysis were used to analyse the area of agricultural land, conversion of agricultural land, and spatial pattern of changes in agricultural land in West Java Province. The data used is time series data in the period of 2005-2014. The result of analysis shows that there are still areas with a high percentage of agricultural land in West Java Province. The rate of conversion of agricultural land varies widely. Cities or regions with very high land conversion rate tend to concentrate in metropolitan areas.

    Full Text Available Abstract This report represents the first exploratory study of Chinese men who provide commercial sex services to other men ("money boys" in Jilin Province, People's Republic of China, through a convenience sample drawn from Changchun and Jilin City. A total of 86 active money boy participants (Changchun, n = 49; Jilin City, n = 37 were surveyed concerning background and demographics, basic HIV transmission knowledge, and sexual practices. The survey indicated that while Jilin Province money boy behavior matches other studies concerning propensity to high risk behavior and significant bridging potential, the Jilin money boys, unlike previous studies, exhibited a high level of basic HIV/AIDS transmission knowledge. In spite of this level of knowledge, none of the participants reported always using a condom in their sexual activities. They also exhibited a high level of awareness of voluntary counseling and testing available in the province, yet relatively few had availed themselves of these services. These preliminary findings will be used as a baseline and springboard for continuing study in the Jilin Province money boy community. Even now, however, it is becoming clear that the dynamics of male commercial sex work may vary greatly depending upon local influences, and will necessitate that future interventions are highly tailored to area-specific circumstances.

We conducted a time series analysis of restaurant and bar revenues in the province of Santa Fe 31 months before and 29 months after the implementation of the 100% smoke-free environment law. The neighboring province of Entre Rios without smoking restrictions at the time of this study, was used as the control province. Average taxable revenues post-legislation in the province of Santa Fe as a whole and in the two most important cities were higher when compared to the total provincial revenue pre-legislation. No significant differences were observed with the total revenue from the province of Entre Rios. We found no statistically significant evidence that the 100% smoke-free environment legislation in the province of Santa Fe, Argentina, had a negative impact on the revenues of local bars and restaurants.

    By using rice growth period, yield and climate observation data during the recent two decades, the impact of climate warming on rice in Northeast China was investigated by mathematical statistics methods. The results indicated that in the three provinces of Northeast China, the average, maximum and minimum temperatures in rice growing season were on the. rise, and the rainfall presented a downward trend during 1989-2009. Compared to 1990s, the rice whole growth periods of Heilongjiang, Jilin and Liaoning provinces in 2000s were prolonged 14 d, 4.5 d and 5.1 d, respectively. The increase of temperature in May, June and September could extend the rice growth period, while that in July would shorten the growth duration. The rice growth duration of registered varieties and experiment sites had a similar increasing trend in Northeast China except for the Heilongjiang Province, and the extension of registered varieties growth period was the main factor causing the prolonged growth period of rice at experiment sites. The change in daily average, minimum and maximum temperatures all could affect the rice yield in Northeast China. The increasing temperature significantly increased the rice yield in Heilongjiang Province, especially in the west region of Sanjiang Plain. Except for the south of Liaoning Province, rice yields in other regions of Northeast China were promoted by increasing temperature. Proper measures for breeding, cultivation and farming, could be adopted to fully improve the adaptation of rice to climate warming in Northeast China.

    Full Text Available In this study economic and welfare impacts of establishing irrigation water market in Qazvin province as well as potentiality of irrigation water transfer under stress irrigation conditions in the cities of Qazvin province were analyzed. To achieve the above objectives, Positive Mathematical Programming model and State Wide Agricultural Production functions were used. To achieve applicable results, the production function with a constant elasticity of substitution and cost function with an exponential form were included into the Positive Mathematical Programming model was imported. The study data for the year 2011-2012 was collected by asking the relevant offices in each city of Qazvin province. The proposed model was solved in six successive stages using the GAMS software. After solving the model, amount changes in the area of irrigated crops, farmer's gross profit and labor surplus under the two conditions of “existence of water market” and “lack of water market “at the regional level were calculated. The results showed that establishing irrigation water market increases total irrigated lands for 1/2 percent, total farmer’s gross profit for 1/86 percent and total labor force employed in agriculture for 1/8 percent in the province. Ultimately, considering the supportive and constructive role of regional water markets, it is recommended to provide necessary conditions and tools to establish an optimal use of such a mechanism associated with the type of market in Qazvin province.

    Full Text Available Background: The main purpose of this study was to analyze and assess the development level of health services in Kermanshah province from the perspective of social justice in 2010. Methods: The data extracted from the statistical yearbooks in Statistical Center of Iran and Governor's House in Kermanshah Province were studied by Division by Mean and Principal Component Methods in the framework of GIS, SPSS and Excel software using thirteen indicators of access to health. Results: Findings indicated that, based on the composite index gained, Kermanshah, Qasr-e Shirin and Paveh cities were the most advantaged in terms of a range of health indicators and Salas Babajani, Ravansar and Dalaho were the most disadvantaged cities. Conclusion: Factors such as lack of spatial planning perspective, special concern for the provision of health services in war-torn cities and motivation to work in the hometown, have affected this issue. Thus, the data indicate lack of balance and proportion of the quantity and distribution of health services to the population of the cities as well as inequality in citizens’ access to the civil welfare.

    Full Text Available Yucheng City is located in northwestern Shandong Province, China, and is situated on the Huang-Huai-Hai Plain, the largest alluvial plain in China. In this study, 86 surface soil samples were collected in Yucheng City and analyzed for cation exchange capacity (CEC, soil organic matter (SOM, pH, available phosphorus (avail. P, phosphorus (P, aluminum (Al, and iron (Fe. These soils were also analyzed for ‘total’ chromium (Cr, nickel (Ni, copper (Cu, zinc (Zn, arsenic (As, mercury (Hg, cadmium (Cd, and lead (Pb, together with 92 wheat samples and 37 corn samples. There was no obvious heavy metal contamination in the soil and irrigation water. But the long-term accumulation of heavy metals in soil has lead to an increase of Ni, As, Hg and Pb concentrations in some of wheat and corn samples and Cd in wheat samples. Because of the numerous sources of soil heavy metals and the lower level of heavy metal in irrigation water, there is no significant relation between soil heavy metal concentrations and irrigation water concentrations. Cr, Ni were mainly from the indigenous clay minerals according to multivariate analysis. Little contribution to soil heavy metal contents from agricultural fertilizer use was found and the local anomalies of As, Cd, Hg, Pb in wheat and corn grain are attributed to the interactive effects of irrigation and fertilizer used. Aerial Hg, however may also be the source of Hg for soil, wheat and corn.

    Carbon footprint is a new method to measure carbon emissions, and the ecological compensation criterion can be determined according to the regional carbon footprint and carbon carrying capacity. The spatial and temporal patterns of ecological compensation criterion were studied among 11 cities in Jiangxi Province using carbon footprint, carbon capacity and carbon surplus/deficit models. Our results found that carbon footprint in Jiangxi Province showed a rapid growth trend from 2000 to 2013, with an average annual growth rate of 8.7%. The carbon carrying capacity always remained surplus, but the net carbon surplus amount decreased from 2000 to 2013. Among the 11 cities, Nanchang and Jiujiang made the biggest contribution to total carbon emission, and Ganzhou, Ji'an and Shangrao had provided the largest contribution to carbon total absorption. In 2013, the total carbon surplus amount was 2.273 billion yuan in Jiangxi Province. Ganzhou, Ji'an, Fuzhou and Shangrao should be given priority to ecological compensation money. These results could provide a scientific basis for the establishment of ecological compensation mechanism in Jiangxi Province and the transfer of CO 2 emission rights.

    Fueled by internal migration, Manila's rapid population has left the philippine capital unable to provide basic services to the city's population. With an annual growth rate of 2.3%, Manila's current population of 8 million is expected to increase to 10 million by the year 2000. The number of migrants to the city has steadily increased over the last 20 years; a recent study indicates that 1/2 of the population currently living in the Manila metropolitan area was born in the province. The growth that began in the 1970 has coincided with increases in the birth rate. As one expert noted, by the year 2000, 1/2 of the city's growth will be due to a high birth rate. The rapidly growing population has made it difficult for the government to provide adequate food, water systems, and other services. The increasing number of people living in squalor are at great risk on contracting communicable diseases, and suffer from poor maternal and child health, inadequate nutrition, and lack safe drinking water and waste disposal systems. Most of the migrants come to the city looking for employment and opportunity, but many are left economically trapped, working in low-paying and often gruelling jobs. Critics attribute the population imbalance to government policies that have favored the city and neglected the countryside. Realizing the dangers associated with the massive urban growth, the government has begun to address the problem. It has asked business to invest in the countryside, it has built roads and bridges there to spur economic growth, and has tried to convince people to return to the province.

    Yunnan Province is located in southwestern China and neighbors the Southeast Asian countries, all of which are dengue-endemic areas. In 2000-2013, sporadic imported cases of dengue fever (DF) were reported almost annually in Yunnan Province. During 2013-2015, we confirmed that a large-scale indigenous DF outbreak emerged in cities of Yunnan Province near the China-Myanmar-Laos border. Epidemiological characteristics of DF in Yunnan Province during 2013-2015 were evaluated by retrospective analysis. A total of 232 dengue virus (DENV)-positive sera were randomly collected for sequence analysis of the capsid/premembrane region of DENV from patients with DF in Yunnan Province. The envelope gene of DENV isolates was also amplified and sequenced. Phylogenetic analyses were performed using the neighbor-joining method with the Tajima-Nei model. Phylogenetically, all DENV-positive samples could be classified into DENV-1 genotype I and DENV-2 Asian I genotype during 2013-2015 and DENV-4 genotype I in 2015 from Ruili City; and DENV-3 genotype II in 2013 and DENV-2 Cosmopolitan genotype in 2015 from Xishuangbanna Prefecture. Our results indicated that imported DF from patients from Laos and Myanmar was the primary cause of the DF epidemic in Yunnan Province. Additionally, DENV strains of all four serotypes were identified in indigenous cases in Yunnan Province during the same time period, while the dengue epidemic pattern observed in southwestern Yunnan showed characteristics of a hypoendemic nature: circulation of DENV-1 and DENV-2 over consecutive years.

    Full Text Available This study investigated diarrheic broiler and layer chickens (60 days; n=64 for E. bieneusi genotypes in northeast China and evaluated the potential roles of chickens and pigs in zoonotic transmission of microsporidiosis. Two 45-day-old layer chickens in city Jixi, Heilongjiang province and one 23-day-old broiler chicken in city Songyuan, Jilin province were identified to harbor a human-pathogenic E. bieneusi genotype Henan-IV and a new genotype named CC-1, respectively, by nested PCR and sequence analysis of the ribosomal internal transcribed spacer (ITS. Eleven of 64 (17.2% duodenal mucosal specimens from pigs in city Tianjin, city Tongliao of Inner Mongolia, cities Jilin and Songyuan of Jilin province, and cities Daqing, Harbin, and Suihua of Heilongjiang province, were positive for E. bieneusi, with the infection rates of weaned pigs (35%, 7/20 significantly higher than preweaned ones (3.6%, 1/28; P<0.05. Nucleotide sequences of the ITS were obtained from 6 pig specimens, belonging to 3 known genotypes CHN7, EbpC, and Henan-IV. That the previous reports have described the occurrence of genotypes EbpC and Henan-IV in humans and EbpC in wastewater in central China and the clustering of genotypes CC-1 and CHN7 into a major phylogenetic group of E. bieneusi genotypes with zoonotic potential indicated that chickens and pigs could be potential sources of human micorsporidiosis. To our knowledge, this is the first report describing the existence of zoonotic E. bieneusi genotypes in diarrheic chickens.

    Full Text Available Background: In recent years, overweight and obesity have dramatically increased in many countries, and this trend is also visible among children. Childhood obesity will increase the chance of obesity and its associated diseases in adulthood. This study was aimed to investigate the prevalence and determinants of overweight and obesity in middle school students of Pakdasht. Methods: In this cross-sectional study, 995 female students were selected from all middle schools of Pakdasht city, Tehran Province by stratified random sampling method. The required information on demographic variables, social determinants of health, type of entertainment, daily physical activity and eating habits was collected and Body Mass Index (BMI was calculated. Results: The mean age of students was 12.6 years. Finally, 9.1% and 15.1% of the students were obese and overweight, respectively. The results of univariate analysis showed that overweight and obesity were significantly associated with age, type of transportation to school, time of computer use, first-degree family history of obesity and daily physical activity. Overweight and obesity were also independently related to type of transportation to school, time of computer use, first-degree family history of obesity, birth weight and daily physical activity based on the results of multivariate analysis. Conclusion: Considering the relatively high prevalence of overweight and obesity in middle school students, it is necessary to design and implement ongoing interventional and multidimensional programms in order to declin or eliminate the mentioned risk factors.

    Full Text Available This paper analyses the problems derived from the metropolitan cities entities in Italy and the simultaneous reform of the provinces. These two issues are part of a broader and current Italian political debate related to targets for reduction of public spending and have to do with the achievement of a new order of local government different from that established in the Title V of the Italian Constitution after its 2001 reform. After an examination of previous attempts to regulate metropolitan cities entities, the article examines the aspects contained in decree law on spending review (d.l. n. 95/2012. In this way, the article aims to highlight both the difficulties and incoherencies of the identification of administrative functions and of the general structure to be assigned to the new level of government (the metropolitan city, provided in the Italian Constitution in 2001 but not yet established. Consequently, the article considers the effects that this new model has upon the other and already existing levels of government (such as municipalities, as provinces and as regions.

    Background: Few studies have assessed the impact of residential home characteristics and home environmental risk factors on respiratory diseases in Chinese women. Therefore, this study sought to determine the association between residential home features, domestic pets, home renovation and other indoor environmental risk factors with respiratory health outcomes of Chinese women. Methods: This cross-sectional study included a study sample of 30,780 Chinese women aged 23 to 49 from 25 districts of seven cities in Liaoning Province, Northeast China. Information on respiratory health, residential characteristics, and indoor air pollution sources was obtained by a standard questionnaire from the American Thoracic Society. Multivariable logistic regression was used to estimate prevalence odds ratios (POR) and 95% confidence interval (95%CI). Results: The odds of respiratory diseases were higher for those who lived near the main road, or near ambient air pollution sources. Pet-keeping was associated with increased odds of chronic bronchitis (POR = 1.40; 95%CI: 1.09–1.81) and doctor-diagnosed asthma (POR = 2.07; 95%CI: 1.18–3.64). Additionally, humidifier use was associated with increased odds of chronic bronchitis (POR = 1.44; 95%CI: 1.07–1.94). Home renovation in recent 2 years was associated with increased likelihood of allergic rhinitis (POR = 1.39; 95%CI 1.17–1.64). Conclusion: Home renovation and residential home environmental risk factors were associated with an increased likelihood of respiratory morbidity among Chinese women. - Highlights: • Relatively few significant associations were observed. • Pet ownership was associated with increased odds of asthma and chronic bronchitis. • Home renovation was associated with increased odds of allergic rhinitis in women. • Humidifier use was associated with increased odds of chronic bronchitis in women.

    To study the heavy metal contamination status in river water and mud in the suburb of a city in Henan Province. Typical sampling method is used to select a farmland irrigation river of the suburb of a city. Use the atomic absorption spectrophotometry, and measure the heavy metal cadmium (Cd), copper (Cu), lead (Pb) in the river water samples and mud samples by graphite furnace method and flame method, respectively. The results of water were compared with GB 3838-2002, Environmental Quality Standards for Surface Water, and GB 5084-2005, Standards for Irrigation Water Quality. The results of mud were compared with national soil background value. The contents of Cu and Cd in the river samples do not exceed the standard, and that of Pb is 3 to 6 times higher than the standard. According to the single factor pollution index method, the single factor pollution indice of Cu, and Cd in the river are less than 0.2 and are of clean level, while that of Pb reaches 6.84, indicating the Pb pollution in river water is severe. Cu in mud is more than 4 times of the soil background value, and that of Cd is more than 69 times of the soil background value, and that of Pb is more than 2 times of the soil background value. The single item pollution index indicates, in mud, the pollution index of Pb is 2.5, medium level pollution. The pollution indice of Cu and Cd in mud are more than 3, is severe pollution, and the Cd pollution is especially heavy, and the single pollution index reaches 67.76. The comprehensive pollution indice of the river and the mud are 5.346 and 84.115, respectively, indicating that both are at heavy pollution level. The main pollution source of the river originates from Pb, and that of the mud is from Cd and it is required to take measure and control as early as possible.

    This study examined population mobility among residents of 5 cities in China: Wuhan, Beijing, Shanghai, Guangzhou, and Shenzhen. Data were obtained from the 1995 Sample Survey of 1% of Wuhan Population and provincial Statistical Yearbooks. The total mobile population in China has increased from 20-80 million during 1982-95. Shanghai is the largest Chinese city. Beijing has a large proportion of international and internal migrants. Guangzhou is a capital city that was the first to adopt economic reforms. Migration fueled development in Shenzhen. A larger mobile population was related to larger population density. The mobile population was 20% in all cities, 30% of central city population, and 140.5% of the central city of Shenzhen. Beijing and Shanghai had the highest growth rates. Construction accounts for the largest percentage of business-related mobile population in Wuhan, Beijing, and Shanghai. Manufacturing accounts for the largest percentage in Guangzhou and Shenzhen. Most of the mobile population in capital cities such as Wuhan and Guangzhou, originates from within the provinces. The largest percentage of mobile population in Beijing and Shanghai come from adjacent provinces. Guangzhou receives many migrants from adjacent Hong Kong, Macao, and Taiwan. 47.8-78.8% of mobile population were farmers. More migrants are men. Educational levels are low. The mobile population contributes to industry and informational/cultural exchange. The migrants detract from urban areas in population pressure on housing and services, shortages of employment, illegal activities and crime, and unplanned births.

    Zhen Zhu

    Full Text Available A rubella outbreak occurred in Anqing city of Anhui province, China, from February to July of 2012, and a total of 241 clinically diagnosed or lab-confirmed patients were reported. The highest number of rubella cases during this outbreak was recorded in teenagers between 10 and 19 years of age who had not previously received the rubella vaccine. Genotyping results indicated that the genotype 2B rubella virus (RV was responsible for the outbreak. However, a phylogenetic analysis showed that the genotype 2B RVs isolated in Anqing City were not related to 2B RVs found in other cities of Anhui province and in other provinces of China, thus providing evidence for importation. After importation, the transmission of Anqing RVs was interrupted owing to an effective immunization campaign against rubella, suggesting the timeliness and effectiveness of contingency vaccination. Strengthening rubella surveillance, including the integration of epidemiologic information and laboratory data, is a vital strategy for rubella control and elimination. In addition, except for routine immunization, targeted supplementary immunization activities aimed at susceptible groups according to sero-epidemiological surveillance data also play a key role in stopping the continuous transmission of rubella viruses and in preventing further congenital rubella syndrome cases.

  16. Is ‘Charter-City Status’ a Solution for Financing City Services in Canada — or Is That a Myth?

    Full Text Available In 2007, the province of Ontario effectively granted Toronto “charter-city status,” handing the municipal government a new arsenal of tools it could use to raise additional revenue. Charter-city status has often been held up as a reasonable way to help satisfy municipal-financing demands without cities relying on property taxes and provincial transfers — something municipal politicians have been known to say they very much need. Since Toronto got its charter, however, the city has barely touched these tools. Free to impose municipal levies on bars, cars, land sales, parking lots, billboards and road tolls, the city has so far only implemented a tax on billboards and land transfers. It tried taxing vehicle registrations, but that tax was soon cancelled. Toronto is not unique in that it has been given special legislation to levy municipal taxes beyond traditional property taxes: There are nearly a dozen cities across Canada that now benefit from similar legislation. They have proven even less inclined to use additional revenue tools. Calgary and Edmonton signed a memorandum of understanding with the Alberta government to gain charter-city status; the process has gone no further than that. Most often, the reason Canada’s so-called charter cities do not seize the apparent opportunity provided by this special legislation is that it typically does not provide them that many additional tools. Toronto is, in fact, exceptional in the range of taxes it can use. One possible reason that Canadian charters have been kept within rather confining bounds is that provinces tend to be reluctant to share their tax bases more than they already do through property tax sharing. But if Toronto is any guide, even having a wider scope of taxing powers does not mean a city will take advantage of them. It may be that local politicians relish the idea of new taxes in theory, but recoil at the political reaction the new taxes are sure to provoke. After all, former

    The Fars province is located in the south-west region of Iran where different nuclear sites has been established, such as Bushehr Nuclear Power Plant. In this research, 92 water samples from the water supplies of Shiraz city and springs of the Fars province were investigated with regard to the concentrations of natural radioactive elements, total uranium, 226 Ra, gross alpha and gross beta. 226 Ra concentration was determined by the 222 Rn emanation method. To measure the total uranium concentration, a laser fluorimetry analyzer (UA-3) was used. The mean concentration of 226 Ra in Shiraz's water resources was 23.9 mBq l -1 , while 93% of spring waters have a concentration 2 mBq l -1 . The results of uranium concentration measurements show the mean concentrations of 7.6 and 6 mg l -1 in the water of Shiraz and springs of Fars, respectively. The gross alpha and beta concentrations measured by the evaporation method were lower than the limit of detection of the measuring instruments used in this survey. The mean annual effective doses of infants, children and adults from 238 U and 226 Ra content of Shiraz's water and spring waters were estimated. According to the results of this study, the activity concentration in water samples were below the maximum permissible concentrations determined by the World Health Organization and the US Environmental Protection Agency. Finally, the correlation between 226 Ra and total U activity concentrations and geochemical properties of water samples, i.e. pH, total dissolve solids and SO 4 2- , were estimated. (authors)

    Polychlorinated biphenyl (PCB) concentrations in human serum samples pooled by donor age and sex (≥60, 50-59, 40-49, 30-39, and 20-29 years old) were determined. The pooled samples were supplied by hospitals in five Chinese cities, which were Yitong (Jilin Province), Weifang (Shandong Province), Ganzi (Sichuan Province), Huaihua (Hunan Province), and Lingshui (Hainan Province). The total PCB concentrations were relatively low compared with concentrations that have been found in other parts of the world. Pentachlorobiphenyls were the dominant PCBs. The total PCB concentrations and the concentrations of most of the pentachlorobiphenyl congeners were slightly higher in the samples from younger donors than in the samples from older donors. The results indicated there is a new source of PCBs in China. Heptachlorobiphenyls in Lingshui may have been transported from Vietnam. Statistical analysis showed that young and old people had been exposed to different sources of PCBs. PCB 126 contributed more than the other dioxin-like PCBs to the total toxic equivalents when the samples were examined as a whole or by city, and the total toxic equivalents were higher in younger people than in older people for the whole sample set and for the Yitong samples.

    By means of osculation value method, several provinces are selected to study the energy saving and emission reduction effect of nuclear power from provincial range according to the statistic data in 2010. Theoretically, nuclear power effect is reducing the consumption of non-renewable energy such as coal and reducing the release of pollutants such as CO 2 . The result shows that the comprehensive evaluation of energy saving and emission reduction effect in Zhejiang and Jiangsu provinces are the best. In comparison, Guangdong province falls behind Hubei and Fujian provinces. Total consumption of coal per unit of GDP in Guangdong, Zhejiang, and Jiangsu provinces is apparently lower than that of Hebei, Shanxi, Liaoning, and Hubei provinces. However, total release of SO 2 and NOx, etc. is apparently reduced in provinces with nuclear power, compared with provinces without nuclear power. But total release of CO 2 from thermal power generation (coal) per unit of GDP is not apparently reduced in provinces with nuclear power than those without. (authors)

    Background : The evidence of increased mortality attributable to extreme temperatures is widely characterized in climate-health studies. However, few of these studies have examined the role of humidity on temperature-mortality association. We investigated the joint effect between temperature and humidity on cardiovascular disease (CVD) mortality in Zhejiang Province, China. Methods : We collected data on daily meteorological and CVD mortality from 11 cities in Zhejiang Province during 2010-2013. We first applied time-series Poisson regression analysis within the framework of distributed lag non-linear models to estimate the city-specific effect of temperature and humidity on CVD mortality, after controlling for temporal trends and potential confounding variables. We then applied a multivariate meta-analytical model to pool the effect estimates in the 11 cities to generate an overall provincial estimate. The joint effects between them were calculated by the attributable fraction (AF). The analyses were further stratified by gender, age group, education level, and location of cities. Results : In total, 120,544 CVD deaths were recorded in this study. The mean values of temperature and humidity were 17.6 °C and 72.3%. The joint effect between low temperature and high humidity had the greatest impact on the CVD death burden over a lag of 0-21 days with a significant AF of 31.36% (95% eCI: 14.79-38.41%), while in a condition of low temperature and low humidity with a significant AF of 16.74% (95% eCI: 0.89, 24.44). The AFs were higher at low temperature and high humidity in different subgroups. When considering the levels of humidity, the AFs were significant at low temperature and high humidity for males, youth, those with a low level of education, and coastal area people. Conclusions : The combination of low temperature and high humidity had the greatest impact on the CVD death burden in Zhejiang Province. This evidence has important implications for developing CVD

By the modernization processes of the second half of the XIX century belong urbanization, industrialization, bureaucratization et al. Samara province during the period belongs to the vast provinces of European Russia and at the end of the XIX century has an economically developed province of the Middle Volga. Agriculture ranks first place in the economic development of the Samara province, therefore industrial production is subject to the processing of agricultural and livestock products. In the second half of the twentieth century on the territory of the Samara province were industrial company, which were at different stages of economic development in the form of property and on the organization of manufacture. By the end of the XIX century, the level of industrial production is much higher than the pre-reform figures, but still inferior to agriculture. During the study period in the Samara province formed the main directions of the region's industry, such as of animal products (skinner, plants furnace animal fat, plant products (churn factory, and conversing minerals (brickyard. The growth and size of cities has determined the pace and scope of development of the industry.

    Full Text Available There is a direct relation between the prevalence of some parasitic diseases and the presence of those etiologic agents in water. The purpose of this research was to determine the contamination rate of wells drinking water to parasites in Mazandaran province in the north of Iran. 989 water samples were randomly taken based on the population of towns and number of health centers from 12 cities of Mazandaran province and transferred to the laboratory in sterile containers. Water samples were then filtered and analyzed according to the World Health Organization guidelines. Direct method and Gram staining procedure were used to identify the parasites. If cryptosporidium was seen, floatation (sheather’s sugar and modified Ziehl-Neelsen staining method were performed. Parasites count was undertaken using McMaster counting slide (0.3 mL. 197 out of 989 water samples were contaminated with different parasites. From 197 contaminated samples, 20 different types of parasites were separated of which 53 (26.9% were pathogenic, 100 (50.8% non pathogenic, and 44 non-infective stages of parasites. Distance between wells and sources of contamination, type of water distribution systems, city and chlorination status had significantly statistical relationship with contamination prevalence (p<0.001. According to the results and considering the direct correlation between safe water and human health, proper implementation of providing hygienic drinking water should be enforced.

    Full Text Available Background: Anecdotal information has suggested that sodium benzoate is used with more than permissible doses during production steps of food products especially pickles and pickled cucumbers in food producing factories in Markazi province and other food producing factories . The present study was done to evaluate factual concentration of sodium benzoate in these products. Methods: In this study, 8 samples from canned pickled cucumbers and 10 samples from canned pickles were randomly gathered from food production factories in Markazi province between March and September 2010. Also, 25 samples from canned pickled cucumbers and 15 samples from canned pickles and 7 samples of bulk cargo pickled cucumbers were collected from the other provinces in Arak city. Sodium benzoate level was determined in the samples using UV-VIS spectrophotometry method. The determined values were analyzed by N-par test using SPSS software version 16.0. Results: Sodium benzoate level was near zero in the samples of canned pickles and pickled cucumbers from producing factories. This was 200-400 PPM in 7 samples from bulk cargo pickled cucumbers which was higher than permissible dose. There was not a statistically significant difference between mean benzoate level of canned pickles and pickled cucumbers produced in Markazi providence factories and other food factories. Benzoate level was significantly higher than permissible dose in bulk cargo pickled cucumbers. Conclusion: Food products from production factories do not have higher than permissible level of sodium benzoate; however, this is higher in bulk cargo pickled cucumbers. Hence, stricter control on bulk cargo pickled cucumber products is recommended.

    Full Text Available In China, a growing number of adolescents have experienced traumatic events that have resulted in PTSD (post-traumatic stress disorder. Post-traumatic symptoms are common psychological problems in adolescents who have experienced traumatic events. However, existing studies tend to focus on the factors influencing PTSD, such as the response styles and social support, and studies on the relationships between parenting style, resilience and post-traumatic symptoms are still rare.To analyze the relationships between parenting style, resilience and post-traumatic symptoms among adolescents in China.A cross-sectional survey was conducted from June to December 2013 in the Liaoning Province, China. N = 5765 adolescents (aged 12 to 18 years old were ultimately chosen to participate. The Chinese version of the Essen Trauma Inventory for Kids and Juveniles (ETI-KJ, a modified version of the Parental Authority Questionnaire, and the Chinese Resilience Scale were used to estimate the post-traumatic symptoms, parenting style, and resilience, respectively. Pearson's correlations, multiple linear regression analyses and structural equation modeling (SEM were applied to analyze the data.Of the adolescents, 39.76% (N = 2292 had been exposed to traumatic events during their lives. The prevalence of probable PTSD at the time of the interview (one-month-prevalence was 12.65%. Parenting style and resilience were significantly associated with post-traumatic symptoms. According to the SEM, parenting style had a significant direct effect on resilience (0.70, P<0.01 and post-traumatic symptoms (-0.15, P<0.05, and resilience had a significant direct effect on the post-traumatic symptoms (-0.43, P<0.01. Furthermore, parenting style had a significant indirect effect (-0.43×0.70 = -0.30. P<0.01 on the post-traumatic symptoms through resilience.

    We mapped leukemia risk among children and youths in the Azuay province, Rio Paute river basin, Ecuador, in 2000-2010, using a Bayesian disease mapping model. We assessed the comprehensiveness of the list of leukemia cases from the Sociedad de Lucha contra el Càncer en el Ecuador (SOLCA) Hospital in Cuenca, the only referral center for oncology in the whole Rio Paute area, by comparison to the Quito cancer registry. Risk of leukemia did not vary significantly by canton within the Azuay province. However, a moderate increase in risk of borderline statistical significance was observed in the city of Cuenca and particularly among males in a heavily industrialized parish, who had an almost eight-fold excess (95% CI 3.03, 20.39, p = 0.01) of AML. Analytical studies are warranted to properly address specific etiological factor of leukemia among children and youths of the Azuay province of Ecuador.

    Full Text Available Dalian is the second–most important city in the southern part of Liaoning Province in northeast China. The city can trace its history back to the Qingniwa settlement. This settlement was occupied from 1858 until 1950 in succession by the British, Japanese and Russian Empires, with each imposing its own building styles on the city. However, from 1950, when the city was finally returned to China by the Russians, who had captured it from the Japanese during the Second World War, most of the imperial buildings and sites were lost to redevelopment within the city. The most dramatic changes have taken place since 1984, when the city was declared a Special Economic Zone, and particularly during the 1990s, when Bo Xilai became the mayor and introduced parks, extensive motorways and many traffic circles. At present, having lost most of its traditional built environment, Dalian is a modern city marked by dramatic housing developments and dominated by multi-family high-rise buildings to accommodate its population of 5.72 million. In 2011, a survey was conducted among 400 inhabitants of the city to ascertain their perceptions concerning life in Dalian and the Dalian Development Zone, their living conditions and their level of satisfaction with their housing. From the survey, it was clear that the majority of the interviewees were uncertain about the variables concerning the structural quality of their housing units and the nature, quality and accessibility of the services provided. However, most of them indicated that public transport, open spaces, parks and recreational facilities were within easy reach of their housing units.

    High consumption of bakery products such as cream-filled pastries may cause serious health risks and food poisoning to humans. Therefore, investigation of the microbial and chemical qualities of bakery products containing cream is necessary. The purpose of the present study was to investigate the chemical qualities and microbial contaminations of cream-filled pastries collected from confectioneries located in six cities in Chaharmahal Va Bakhtiari province (Southwestern Iran). Microbial tests and chemical characteristics (fat and acidity level) were done on 228 cream-filled pastries samples that were collected randomly from various confectioneries. After microbial tests, it was found that 33.33% of all samples were contaminated by microbial agents. The microbial tests showed that Shahrekord (10.09%) and Broujen (9.21%) cities had high levels of contamination and in Koohrang (1.31%) it was low compared with the other four cities. High contamination of coliforms (61.84%), staphylococci (48.68%), and yeast (27.63%) were observed in almost all samples. The chemical analysis showed maximum amounts of fat content and titratable acidity in cream-filled pastry samples obtained from Lordegan and Shahrekord cities, respectively. The findings of the present work demonstrated that the microbial contamination and chemical quality of cream-filled pastries produced in confectionaries of Chaharmahal Va Bakhtiari province were not in acceptable ranges. These problems may be related to fecal contamination of cream samples or lack of hygiene by handlers and it is necessary to observe the standards of hygiene and to develop safe food handling techniques and aseptic pastry manufacturing systems in some confectioneries of Chaharmahal Va Bakhtiari province.

    The Lower Congo is one of eleven provinces in the Democratic Republic of Congo, and is located southwest of Kinshasa Town Province. It has an area of approximately 53.947 km2 with a population of 1,504,361 at an estimated 237 persons per km2. The Province comprises five districts, including Lukaya and Cataracts where rural poverty is severe and the population struggle to make a living through agriculture and woodcutting. These activities result in excessive resource exploitation. The high demand for foodstuffs and the high consumption of wood (for energy, construction and export) in Kinshasa, the capital city of the Democratic Republic of Congo and the expanding towns of Matadi and Boma in the Lower Congo Province, are speeding the deforestation rate and unbalancing forest ecosystems. In addition there is the stress resulting from reduced josher (the rest period for agriculture ground), plus climate change and erosion. The phenomena that that we need to address in these two districts include deforestation, reduced josher, excessive agriculture, erosion, burning and climate change which taken together largely explain the current soil degradation. These areas are marked by excessive post deforestation savannah formation and extended areas of sandy soil, distributed throughout grass and shrub savannahs. This desertification, which is rampant in Lukaya and Cataracts, risks imprisoning the rural population in a vicious cycle of poverty if adequate solutions are not found.

    Full Text Available The traditional concepts of water resource development and utilization have caused serious hydrological and environmental issues in some regions. In addition, policy issues in China have led to a severe water crisis. The quantitative accounting of water resources is a theoretical approach to solving these problems. In this paper, 13 indicators were selected from four classes, including resources, the environment, society, and efficiency, and a case study of Jinan, Shandong Province, was performed using a set pair analysis model to calculate the water resource assets from 2011–2015. In previous methods of water resource accounting, the water quality was not considered; therefore, the loss coefficient of water resource assets was proposed to improve the reliability of accounting. According to the relationships among the unit price of water, water quantity, and water quality, physical and quantitative accounting methods were used to create water balance sheets from 2011–2015. The calculation results showed that the physical change in water resource assets in Jinan City was −30 million m 3 , and water resource assets initially increased and then decreased. In 2011, 2012, 2013, 2014, and 2015, water resource assets totalled 36.5 million USD, 45.9 million USD, 66.7 million USD, 35.5 million USD, and 37.5 million USD, respectively (at 6.4588, 6.3125, 6.1932, 6.2166, 6.2284 USRMB, respectively. This initial accounting provides quantitative and physical support for the improved management of water resources.

    Full Text Available The tourism sector has a significant contribution to the economy of Manado City, North Sulawesi Province. However, on the other hand, it has a negative effect on the increase in the number of child commercial sexual exploitation victims and makes children into commercial sex workers. Despite not effective, the Local Government of Manado City, North Sulawesi Province, has made efforts to cope with the child commercial sexual exploitation victims. In connection with the case, this study is designed to analyze the causes of ineffectiveness of Local Government efforts in tackling child commercial sexual exploitation victims. The study was conducted in tourism area of Manado City, North Sulawesi Province. The informants involved in this study were divided into two types: experts and non-experts. The informants were determined by using Opportunistic Sampling, and the sampling is using Snowball Sampling. The results of the study showed that the development of tourism sector has negative effect on children in the communities. Efforts made to cope with child commercial sexual exploitation victims by the local government and relevant parties have not been effective due to limited allocation of budgets and skilled, quality human resources, the lack of harmonious understanding between police with judges and public prosecutors as law apparatus, supervision, and protection of victims in solving the cases of child commercial sexual exploitation victims, the implementation of action committee’s duties and responsibility have been not effect, the number of obstacles facing them.

    To understand the situation of diarrhea cases treatment modules in the areas and to provide reference data for setting up national strategies for treatment and control of diarrhea diseases. Using the method of multistage and cluster random sampling, we selected twelve counties/cities and 60 streets communities/villages from Guangdong, Henan and Gansu provinces that representing three kinds of economic development. According to the definition of diarrhea case published by World Health Organization, we conducted a four-time investigation at the community level in four different seasons. The overall incidence of diarrhea within two weeks was 0.79% (95%CI: 0.74% - 0.84%) in the residents from twelve counties/districts in Guangdong, Henan and Gansu. The incidence rate within two weeks under the 5 years old was 2.30% (95%CI: 1.96% - 2.67%), obviously higher than the incidence rates seen in other age groups. The average percentage of visiting a doctor seeking for help on diarrhea within the two weeks was 55.89% for the three provinces. The highest percentage was 79.88% in the age group under 5 years old. 35.38% of the patients with diarrhea in urban area went to the community or street clinics for treatment, but 75.04% of the diarrhea cases in rural areas went to see village or private rural doctors. Factors influencing the behaviors of visiting a doctor seeking for help were found by logistic Regression method. It was found that factors as: when diarrhea cases with voluminous or soft-rice like watery stools or with dark blood stools; when a patient was with fever, more episodes per day or with longer duration, the patients would turn more to the doctors for help. Diarrhea cases from the rural areas would see doctors more often than the cases from the urban areas. People having had partial 'new rural medical insurance' would see doctors more often than those without medical insurance. We studied the modules of diarrhea case treatment between the urban and rural area in

    To analyze the status quo of quantitative classification in Hunan Province catering industry, and to discuss the countermeasures in-depth. According to relevant laws and regulations, and after referring to Daily supervision and quantitative scoring sheet and consulting experts, a checklist of key supervision indicators was made. The implementation of quantitative classification in 10 cities in Hunan Province was studied, and the status quo was analyzed. All the 390 catering units implemented quantitative classified management. The larger the catering enterprise, the higher level of quantitative classification. In addition to cafeterias, the smaller the catering units, the higher point of deduction, and snack bars and beverage stores were the highest. For those quantified and classified as C and D, the point of deduction was higher in the procurement and storage of raw materials, operation processing and other aspects. The quantitative classification of Hunan Province has relatively wide coverage. There are hidden risks in food security in small catering units, snack bars, and beverage stores. The food hygienic condition of Hunan Province needs to be improved.

    In China, the gender ratio of suicide rates did not match the Western patterns, which was higher for females than males. However, the rural men were at relatively high risk of suicide in Liaoning province. Impulsivity was an important factor of suicide behaviors, but there was a lack of studies in China. This research aimed to study the relationship between impulsive personality traits and suicidal behavior among Chinese rural youths. Suicides were consecutively sampled from six randomly selected counties in Liaoning Province in China. Between 2005 and 2007, a total of 162 suicide victims were enrolled in the study along with 162 community controls matched for age, gender, and location. The psychological autopsy method was used to collect data from informants knowledgeable about the selected suicide victims and controls. The results showed the suicide victims in the study were more likely to demonstrate dysfunctional impulsivity and less likely to demonstrate functional impulsivity compared with the controls. Mental disorders, acute negative life events, and dysfunctional impulsivity contributed to the risk of suicide; educational and functional impulsivity were protective factors. Suicide prevention efforts in rural China may address impulsivity.

    During the last 2 years of the project, we have tried to develop the technology to make a distinction of the production areas for Korean ginsengs cultivated in the various provinces in Korea and foreign countries. It will contribute to secure the health food safety for public and stability of its market. In this year, we collected ginseng samples cultivated in the northeastern province in Chinese mainland such as Liaoning province, Jilin province and Baekdu mountain within Jilin province. 10 ginseng samples were collected at each province. The elemental concentrations in the ginseng were analyzed by using a neutron activation analysis technique at the HANARO research reactor. The distinction of production area was made by using a statistical software. As a result, the Chinese Korean ginsengs were certainly differentiated from those cultivated in the famous province in Korea though there was a limitation that the number of our sample we analyzed is very small.

    In the context of global climate change, drought has become an important factor that affects the maize yield in China. To analyse the impact of drought on maize yield loss in Northeast China in current and future climate scenarios, the Composite Meteorological Drought Index (CI) is introduced to reconstruct the following drought indicators: drought accumulative days (DAD), drought accumulative intensity (DAI), and consecutive drought days (CDD). These three drought indicators are used to describe the three-dimensional characteristics of drought in this study. Sen's slope method and three-dimensional copula functions are adopted to analyse the variety of drought features, and Ensemble Empirical Mode Decomposition (EEMD) is used to analyse the variations in maize yield. A temporal assessment of the standardized yield residuals series (SYRS) of maize from 1961 to 2014 is conducted. A panel regression model is applied to demonstrate the drought impact on maize yield at various growth stages under the RCP4.5 scenario. The results show that the drought risk level for midwest Jilin Province, western Liaoning, and eastern Heilongjiang increase with global warming in the current scenario. The shorter three-dimensional joint return periods, 44-80 yr, were mainly located in western Jilin Province, Liaodong Peninsula, and northwestern Liaoning. Eastern Heilongjiang has a slightly longer joint return period of 80-100 yr. The SYRS shows a strong statistical correlation with drought indicator variations; drought-prone regions exhibit strong positive correlations. In comparison, excess precipitation regions show strong negative correlations with drought indicators in most growth stages. Drought indicators have a relatively strong association with SYRS at the milky-mature maize growth stage, and the occurrence of drought during this period primarily determines the maize yield changes in the future. Maize yield changes are -2.04%, -2.65% and -1.57% for Liaoning, Jilin, and

    Full Text Available Abstract Background The 2003 heat wave had a high impact on mortality in Europe, which made necessary to develop heat health watch warning systems. In Spain this was carried-out by the Ministry of Health in 2004, being based on exceeding of city-specific simultaneous thresholds of minimum and maximum daily temperatures. The aim of this study is to assess effectiveness of the official thresholds established by the Ministry of Health for each provincial capital city, by quantifying and comparing the short-term effects of above-threshold days on total daily mortality. Methods Total daily mortality and minimum and maximum temperatures for the 52 capitals of province in Spain were collected during summer months (June to September for the study period 1995-2004. Data was analysed using GEE for Poisson regression. Relative Risk (RR of total daily mortality was quantified for the current day of official thresholds exceeded. Results The number of days in which the thresholds were exceeded show great inconsistency, with provinces with great number of exceeded days adjacent to provinces that did not exceed or rarely exceeded. The average overall excess risk of dying during an extreme heat day was about 25% (RR = 1.24; 95% confidence interval (CI = [1.19-1.30]. Relative risks showed a significant heterogeneity between cities (I2 = 54.9%. Western situation and low mean summer temperatures were associated with higher relative risks, suggesting thresholds may have been set too high in these areas. Conclusions This study confirmed that extreme heat days have a considerable impact on total daily mortality in Spain. Official thresholds gave consistent relative risk in the large capital cities. However, in some other cities thresholds

    As an important theme in global climate change and urban sustainable development, the changes of land surface temperature (LST) and surface urban heat island (SUHI) have been more and more focused by urban ecologists. This study used land-use data to identify the urban-rural areas in 285 cities in China and comparatively analyzed LST in urban-rural areas with the perspective of spatial-temporal dynamics heterogeneity. The results showed that, 98.9% of the cities exhibited SUHI effect in summer nighttime and the effect was stronger in northern cities than that in southern cities. In 2010, the mean SUHI intensity was the largest in summer daytime, with 4.6% of the cities having extreme SUHI of over 4°C. From 2001 to 2010, the nighttime LST of most cities increased more quickly in urban areas compared with rural areas, with an increasing tendency of the urban-rural LST difference. The difference in the urban- rural LST change rate was concentrated in the range of 0-0.1°C/year for 68.0% of cities in winter and 70.8% of cities in summer. For the higher LST increasing in urban areas compared with rural areas, there were more cities in summer than winter, indicating that the summer nighttime was the key temporal period for SUHI management. Based on the change slope of urban-rural LST, cities were clustered into four types and the vital and major zones for urban thermal environment management were identified in China. The vital zone included cities in Hunan, Hubei and other central rising provinces as well as the Beibu Gulf of Guangxi Province. The major zone included most of the cities in Central Plain Urban Agglomeration, Yangtze River Delta and Pearl River Delta. These results can provide scientific basis for SUHI adaptation in China.

    After an historical introduction about ancient institutional regime of present Littoria/Latina province (until 1870 organized in Naples kingdom and Papal States), this essay is going to a swift analysis of marshes who reigned all over the land from the periphery of Rome to Fondi, when transient sheperds and woodmen were the only human beings of marshy land. So teachers for that unlettered people came into these lands, and so physicians came to fight against malary, first symbiotic enemy of man. So drainages were tried from Roman's epoch to Medieval and Illuministic one. We'll see Popes, feudal ladies and at last drainage trusts, all working to improve human life before the birth of Latina province. New cities and towns were born just during these trials; after the experiences of Angelo Celli, Italian Red Cross and Istituto per il risanamento antimalarico della regione pontina, many laws looked to medical aid for workers in malaric zones (exactly specified in topographic maps). In 1934 the Comitato provinciale antimalarico was introduced all over italian territory with the R.D.n. 1265.

    Recent studies on regional haze pollution over China come up in general with strong variability of main causes of heavy polluted episodes, in linkage with local specificities, sources and pollution characteristics. This paper therefore aims at elucidating the main specific sources and formation mechanisms of observed strong haze pollution episodes over 1-15 November 2015 in Northeast region considered as one of biggest megacity clusters in China. The Northeast China mega-city cluster, including Heilong Jiang, Jilin and Liaoning provinces, is adjacent to Russia in the north, Mongolian at the west, North Korea at east, and representing key geographical location in the regional and transnational air pollution issues in China due to the presence of heavy industries and intense economic activities. The present study, based on air quality monitoring, remote sensing satellite data and sensitivity experiments carried on the Nested Air Quality Prediction Modeling System (NAQPMS), quantitatively assesses the impact of meteorological conditions and potential contributions from regional chemical transport, intensive energy combustion, illegal emission and biomass burning emissions to PM 2.5 concentration variation. The results indicate strong inversion occurrence at lower atmosphere with weak near-surface wind speed and high relative humidity, leading to PM 2.5 concentration increase of about 30-50%. Intensive energy combustion (plausibly for heating activities) and illegal emission also significantly enhance the overall PM 2.5 accumulation by 100-200 μg m -3 (60-70% increase), against 75-100 μg m -3 from the biomass burning under the northeast-southwest transport pathway, corresponding to a contribution of 10-20% to PM 2.5 concentration increase. Obviously, stagnant meteorological conditions, energy combustion, illegal emission and biomass burning are main drivers of strong haze formation and spatial distribution over Northeast China megacity cluster.

    Full Text Available BACKGROUND: HIV prevalence among men who have sex with men (MSM has increased rapidly. MSM may play a bridging role in the spread of HIV and other STDs from the high-risk population to the general population. Interventions to reduce high-risk behavior are the key to controlling the spreading of HIV in the MSM population and the primary strategy for reducing the spread of AIDS in China. The purpose of the study was to examine the demographic characteristics of MSM, evaluate the HIV-related knowledge of MSM, and identify factors associated with unprotected anal intercourse (UAI among MSM to make recommendations for future research. METHODOLOGY/PRINCIPAL FINDING: A cross-sectional survey was conducted among 293 MSM in Fushun and Huludao City, China. A total of 91 participants (34.0% reported engagement in UAI with a male partner during the previous six months. The results of univariate analysis showed that UAI was associated with older age, lower levels of education, less knowledge about HIV, and not receiving condoms, lubricant, peer education, AIDS counseling, STD checks, and informational materials (p<0.05. In a multivariate logistic regression model, awareness of the major HIV transmission routes (OR = 2.191; 95% CI: 0.869 to 5.524, receiving condoms (OR = 2.164; 95% CI: 1.149 to 4.076, receiving peer education (OR = 2.632; 95% CI: 1.566 to 4.426, and AIDS counseling (OR = 2.347; 95% CI: 1.260 to 4.372 were independently associated with a lower risk of UAI. CONCLUSIONS/SIGNIFICANCE: The study suggested that UAI could be decreased by improving education about AIDS, increasing the promotion of voluntary counseling and testing (VCT, and improving the accessibility and convenience of service.

    This paper first applied material flow analysis (MFA) to construct three levels of regional eco-efficiency indicators, i.e., regional direct eco-efficiency (RDE), regional total eco-efficiency (RTE), and holistic eco-efficiency (HE), and adopted the newly developed data envelopment analysis (DEA) to evaluate the eco-efficiency of Tongling City during the period of 1990-2008. We also applied Malmquist productivity index (MPI) to explore the eco-efficiency change between two following years and its driving factors. The main results were summarized as 1) though the RDE of Tongling City in 1990-2008 kept an increasing trend, its mean eco-efficiency was not high (close to 0.8 in 80% of the years), being lower than that of the RTE and HE, and 2) the RDE change was closely relevant to the improvement in resource management and the technical input in environmental protection in recent years. In order to further improve the RDE of the City, it would be necessary to raise its eco-efficiency via expanding raw material input, reducing domestic extraction, promoting resources productivity, and taking more measures on environmental protection facilities construction.

    Using social network analysis method,this paper made an empirical study on growth of evil forces in land requisition and relocation in City G of Hubei Province. It obtained following results:(i) lawless developers and inefficient public security organs form interested parties of evil forces. Besides,the inward closeness centrality of evil forces is high,manifesting that evil forces independently possess decentralized power of network and have unscrupulous behavior in land requisition and relocation to a certain extent.(ii) Activities of evil forces have complicated spatial correlation and their geographical distribution is uneven,taking on irregular characteristics. In the field of land requisition and relocation,some evil forces are expandi Xng and spreading,while other forces are relatively weak. In conclusion,growth of evil forces comes from premeditation and collaboration of lawless developers,lack of functions and weak attack of public security organs; growth of evil forces has periodic changes,when in power,they will take opportunity to expand,while losing power,they will hide or even disappear.

Primary data were collected through ninety eight semi-structured surveys carried out in the space units that comprise the study area. The selection of the sampling units was accomplished through a non probabilistic method. The results show a set of non similarities among distinctive settlement lines, and even within them, and point to processes of consolidation of the social-territorial fragmentation beyond the main district urban area.

    Taiping Temple is the sole surviving monument from the Xibe people's early history. It is located in Heping District, Shenyang, Liaoning Province. There are differing reports in historical records as to the time of its construction. On the basis of the frequent migrations of the Xibe people, historians agree the most likely construction date is 1707, during the reign of Emperor Kangxi. It was constructed with 60 taels of silver.

    To investigate multicontaminant air pollution in Chinese cities, to quantify the urban population affected and to explore the relationship between air pollution and urban population size. We obtained data for 155 cities with 276 million inhabitants for 2014 from China's air quality monitoring network on concentrations of fine particulate matter measuring under 2.5 μm (PM 2.5 ), coarse particulate matter measuring 2.5 to 10 μm (PM 10 ), nitrogen dioxide (NO 2 ), sulfur dioxide (SO 2 ) and ozone (O 3 ). Concentrations were considered as high, if they exceeded World Health Organization (WHO) guideline limits. Overall, 51% (142 million) of the study population was exposed to mean annual multicontaminant concentrations above WHO limits - east China and the megacities were worst affected. High daily levels of four-contaminant mixtures of PM 2.5 , PM 10 , SO 2 and O 3 and PM 2.5 , PM 10 , SO 2 and NO 2 occurred on up to 110 days in 2014 in many cities, mainly in Shandong and Hebei Provinces. High daily levels of PM 2.5 , PM 10 and SO 2 occurred on over  146 days in 110 cities, mainly in east and central China. High daily levels of mixtures of PM 2.5 and PM 10 , PM 2.5 and SO 2 , and PM 10 and SO 2 occurred on over  146 days in 145 cities, mainly in east China. Surprisingly, multicontaminant air pollution was less frequent in cities with populations over 10 million than in smaller cities. Multicontaminant air pollution was common in Chinese cities. A shift from single-contaminant to multicontaminant evaluations of the health effects of air pollution is needed. China should implement protective measures during future urbanization.

    Full Text Available Mapping spatial patterns of potential biodiversity threats is one of the important steps for effective conservation planning and activities. To determine the spatial patterns of threats in Golestan province, 12 criteria in four main groups including structural (fractal coefficient of perimeter, circularity ratio of area, average slope, compositional aspects of biodiversity (presence of species at risk, non-biological threats (distance to city, distance to village, distance to road, distance to infrastructure, distance to agricultural land, soil pollution, risk of fire and isolation (Nearest Neighbor Index were used. These data layers were digitized in GIS environment and were weighted through Analytical Hierarchy Process. A weighted linear combination was then used to map the spatial pattern of biodiversity threats in the province. Compositional aspect (0.59, non-biological threats (0.23, isolation (0.11, and structural aspect (0.07 were relatively weighted in the order of importance. Central parts of the province and patches in the northern and southern parts were recognized to be more exposed to biodiversity threats. The central parts of the province were mostly threatened by urban, industrial, road and agricultural development, whereas the northern and southern parts were recognized as areas of conservation importance having a variety of threatened birds.

    Full Text Available Background: One of the most common anomalies in newborn infants is cleft lip and/or cleft palate (CL/P. In spite of several studies about the prevalence of this, no investigation evaluated this prevalence in the West and North-West of Iran. With due attention to different ethnic groups in this area, the aim of this study is to investigate whether the distribution of CL/P live births varies regionally in this area of Iran. Materials and Methods: A cross-sectional study was conducted using hospital registry records to identify all children born with CL/P. The hospitals with a maternity unit were selected in the capital cities of four provinces in the West and North-West of Iran, East Azarbaijan, Kurdestan, Gilan, and Markazi. The population under study included all infants born alive from 2008 to 2012. Results: During the study period, 107,317 live births were registered in the hospitals with a maternity unit of four cities, and 52 infants (0.485/1000 live births were born with CL/P. The prevalence in Rasht, Arak, Sanandaj, and Tabriz cities was 0.557, 0.352, 0.503, and 0.559/1000 live births, respectively (P 0.05, whereas the prevalence of CL/P based on sex was statistically different among the four provinces (P < 0.05. Conclusion: This study shows regional variations in the birth prevalence of clefts and various cleft types. The different effects of gender on the birth prevalence of CL/P from city-to-city may be explained environmentally and/or by genetic factors affecting the development of oral clefts.

    There is no information concerning the genotype of Canine parvovirus (CPV) currently circulating in Henan province, China. Therefore, the aim of the present study was to provide insights into the epidemiology and molecular characterization of CPV circulating in Henan province from 2009 to 2014. Nineteen thousand nine hundred seven dogs from pet hospitals in the cities of Luoyang, Anyang, Jiaozuo, Sanmenxia, Xinxiang, Zhengzhou in Henan province between 2009 and 2014 were investigated. Over the 6-year period, 1169 CPV-positive cases were identified and the morbidity of CPV infection ranged from 4.16 to 8.06 %, although morbidity was not significant (P > 0.05) between 2009 and 2014. Factors associated with morbidity included sampling season, dog age, breed, vaccination status, and sex. CPV co-infection with coccidium (10.00 %), canine distemper virus (4.79 %), hookworm (2.40 %), canine coronavirus (1.11 %), roundworm (1.03 %), tapeworm (0.17 %) and Babesia spp. (0.09 %) were observed. The new CPV-2a variant was more prevalent than the new CPV-2b variant in Henan province. CPV 2c was not observed in this study. The epidemiology of CPV infection and identification of the circulating genotypes in Henan province, China from 2009 to 2014 determined that the new CPV-2a variant was more prevalent.

    This paper examines the impact of climate change on children’s health, in the Limpopo Province of South Africa. Twenty one years climatic data were collected to analyse climatic conditions in the province. The study also employs 12 years hospital records of clinically diagnosed climate-related ailments among children under 13 years to examine the incidence, spatio-temporal, age and sex variations of the diseases. Regression analysis was employed to examine the relationships between climatic parameters and incidence of diseases and also to predict distribution of disease by 2050. The results show that the most prevalent diseases were diarrhea (42.4%), followed by respiratory infection (31.3%), asthma (6.6%) and malaria (6.5%). The incidence varied within city, with the high density areas recording the highest proportion (76.7%), followed by the medium (9.4%) and low (2.5%) density residential areas. The most tropical location, Mussina, had the highest incidence of the most prevalent disease, diarrhea, with 59.4%. Mortality rate was higher for males (54.2%). Analysis of 21 years of climatic data show that maximum temperature is positively correlated with years in four cities with r coefficients of 0.50; 0.56, 0.48 and 0.02, thereby indicating local warming. Similarly rainfall decreased over time in all the cities, with r ranging from −0.02 for Bela Bela to r = 0.18 for Makhado. Results of the regression analysis show that 37.9% of disease incidence is accounted for by the combined influence of temperature and rainfall. PMID:22690167

    Objective: To investigate the current status of job burnout in in-service sailors, and to provide a basis for the development of intervention measures for job burnout in sailors. Methods: From September 2015 to May 2016, stratified cluster random sampling was used to select 6 172 in-service sailors from 13 provinces and cities as research subjects. General demographic data including age, education background, and household registration and occupational characteristics such as job position, navigating zone, and nature of employment were collected. The Maslach Burnout Inventory-General Survey (MBI-GS) was used to measure the levels of emotional exhaustion, depersonalization, low occupational efficiency, and job burnout, and the influencing factors for job burnout were also analyzed. Results: Of all 6 172 in-service sailors, 112 (1.8%) had a positive result in emotional exhaustion, 870 (14.1%) had a positive result in depersonalization, and 3 517 (57.0%) had a positive result in low occupational efficiency. Of all sailors, 63.3% had job burnout, among whom 54.1% had mild burnout, 8.7% had moderate burnout, and 0.5% had severe burnout. There was a significant difference in the score of job burnout between the sailors with different ages, education backgrounds, types of household registration, job positions, navigating zones, ornature of employment ( P burnout in in-service sailors ( P burnout in the sailors with an age of 30-39 years, education background of junior college or above, urban registration, a job position of second mate/third engineer, a navigating zone of coastal lines, orthe nature of employment of freelance sailor. Conclusion: There is a high incidence rate of job burnout among in-service sailors, and the sailors with a young age, urban registration, a navigating zone of coastal lines, or thenature of employment of freelance sailor tend to have low occupational efficiency. Related measures should be adopted for active intervention.

    ); in addition, it was seen that high risk areas were not randomly distributed within the province, but showed a sharp clustering. The most perceptible cluster involved a collection of municipalities around the Maglie area (Istat code: 75039), while the association among the municipalities of Otranto, Poggiardo and Santa Cesarea Terme (Istat codes: 75057, 75061, 75072) was more ambiguous. For females, it was noteworthy the significant risk excess in the city of Lecce (Istat code: 75035), where an SMR of 1.83 and rhoi < 0.01 have been registered. BYM model for the province of Lecce: For males, Bayes estimates of relative risks varied around an overall mean of 1.04 with standard deviation of 0.1, with a minimum of 0.77 and a maximum of 1.25. The posterior relative risks for females, although smoothed, showed more variation than for males, ranging form 0.74 to 1.65, around a mean of 0.90 with standard deviation 0.12. For males, 95% posterior credible intervals of relative risks included unity in every area, whereas significantly elevated risk of mortality was confirmed in the Lecce area for females (95% posterior CI: 1.33 - 2.00). BYM model for the whole Apulia: For males, internally standardized maps showed several high risk areas bordering the province of Lecce, belonging to the province of Brindisi, and the presence of a large high risk region, including the southern part of the province of Brindisi and the eastern and southern part of the Salento peninsula, in which an increasing trend in the north-south direction was found.Ecological correlation study with deprivation (Cadum Index): For males, posterior mean of the ecological regression coefficient beta resulted to be 0.04 with 95% posterior credible interval equal to (-0.01, 0.08); similarly, beta was estimated as equal to -0.03 for females (95% posterior credible interval: -0.16, 0.10). Moreover, there was some indication of nonlinearly increasing relative risk with increasing deprivation for higher deprivation

    Full Text Available Human settlement expansion has very important effects on regional population migration, economic balance and ecosystem services. Understanding the evolution of settlement expansion and regional differences is significant for regional sustainability. The results showed that in the past 30 years, the urbanization rate in Jiangsu province was lower. From 1980 to 2010, the expansion area of urban settlement was larger than that of rural settlement. Urban settlement expanded slowly from 1980 to 2005 and strongly from 2005 to 2010. Rural settlement expanded greatly from 1980 to 1995, and 37.14% of settlement was mostly on cropland. The type of urban settlement expansion from 1980 to 1995 and from 2000 to 2005 was compact expansion. Settlement expansion in the south of Jiangsu province was greater than that in the north of Jiangsu province. The spatial pattern of settlement in most cities was a cluster. In the past 30 years, urban and rural settlement expansion had significantly different impacts on the soil and water environment. Urban settlement expansion was great in the south of Jiangsu province and widened the economic and social gap between the south and north of Jiangsu province.

    Transformation of the natural environment will press the humanity to search for the new look at the problems of architecture and urban design. Nowadays passive houses construction is a standard and green roofs are incorporated in the design of contemporary cities. That's why city cluster will be successively transformed into sustainable bionic systems, which allows to protect the nature and stop further degradation and exploitation of public green space. The good examples of contemporary trend of designing in harmony with nature are energy sustainable underground buildings of Malcolm Wells, who in 60s designed his first energy sufficient construction. The underground cities and rock houses were built from the early beginning of architecture, with significant examples of cities: Sanmenxia in China in Henan Province, Matmata (Tunisia), Cappadocia (Turkey), Uplisciche (Georgia) or Brlhovce (Slovakia) etc. The underground buildings and cities, blending in with the background of topography, have a positive influence on the landscape and are energy sustainable. Climate responsive design materials create effective insulation, which allows to maintain the stable temperature inside the buildings. Bioarchitecture improves the microclimate in the neighborhood through increasing oxygen concentration in atmosphere and limiting of CO2 emission. Bioarchitecture represents new direction in changing the design priorities towards being closer with nature and it's needs.

    The present study examines some heavy metals (As, Cd, Co, Cr, Cu, Ni, Pb and Zn) contents in urban soils of 23 cities in Isfahan province, central Iran. For this purpose, 83 topsoil samples were collected and analyzed by ICP-MS. Results showed that the concentrations of As, Cd, Cu, Pb and Zn are higher than background values, while Co, Cr and Ni concentrations are close to the background. Compared with heavy metal concentrations in selected cities around the world, As, Cd, Cu, Pb and Zn concentrations in urban soils of Isfahan are relatively enriched. Moreover, natural background concentrations of Co, Cr and Ni in Isfahan province soil are high and the apparent enrichment relative to other major cities of the world is due to this high background contents. Calculated contamination factor (CF) confirmed that As, Cd, Cu, Pb and Zn are extremely enriched in the urban soils. Furthermore, pollution load index (PLI) and Geoaccumulation index (Igeo) highlighted that highly contaminated cities are mostly affected by pollution from traffic, industries and Shahkuh Pb-Zn mine. Based on hazard quotients (HQ), hazard index (HI) and cancer risk (CR) calculated in this study, human health risk (particularly for Pb and Cd) have reached alarming scales. Results from principle component analysis (PCA) and positive matrix factorization (PMF) introduces three sources for soils heavy metals including mine and industries (mainly for Pb, Zn, Cd and As); urban activities (particularly for Cu, Pb and Zn); and geogenic source (Ni, Co and Cr).

    Uranium was found in Mendoza in 1946 in 'Soberania' and 'Independencia' mines. After its creation in 1950 CNEA, together with Cuyo National University (UNC), developed the mining industry starting with the 'Papagayos' mine. It can be considered the beginning of the systematic exploitation of uranium in the country. In course of time the province of Mendoza passed to get one of the most uraniferous reserve of Argentina and it has accumulated the major production till now. However, in the last years there has been opposition to resume the production in the Sierra Pintada Uranium Manufacturing Complex. There was also a powerful land continuous progress in the field of no energetic applications of nuclear techniques in the province. The most outstanding example is the 'School of Nuclear Medicine Foundation', with installations in Mendoza city and in San Rafael. Besides, there is a research and development group in Cuyo National University devoted to the Nuclear Safety. Finally, we can not fail to mention the Auger Pierre Project, which is building in Malargue an observatory for the study of the cosmic rays. (author) [es

    A total of 79 topsoil samples (ranging from 0 to 20 cm in depth) were collected from a grape cultivation area of Zhangjiakou City, China. The total concentrations of As, Cd, Hg, Cr, Cu, Mn, Ni, Pb, and Zn in soil samples were determined to evaluate pollution levels and associated health risks in each sample. Pollution levels were calculated using enrichment factors (EF) and geoaccumulation index (I geo). Health risks for adults and children were quantified using hazard indexes (HI) and aggregate carcinogenic risks (ACR). The mean concentrations of measured heavy metals Cd, Hg, and Cu, only in the grape cultivation soil samples, were higher than the background values of heavy metals in Hebei Province. According to principal component analysis (PCA), the anthropogenic activities related to agronomic and fossil fuel combustion practices attributed to higher accumulations of Cd, Hg, and Cu, which have slightly polluted about 10-40% of the sampled soils. However, the HI for all of the heavy metals were lower than 1 (within safe limits), and the ACR of As was in the 10(-6)-10(-4) range (a tolerable level). This suggests the absence of both non-carcinogenic and carcinogenic health risks for adults and children through oral ingestion and dermal absorption exposure pathways in the studied area. It should be also noted that the heightened vulnerability of children to health risks was accounted for higher HI and ACR values. Consequently, heavy metal concentrations (e.g., Cd, Hg, Cu) should be periodically monitored in these soils and improved soil management practices are required to minimize possible impacts on children's health.

    A new species of cyst nematode, Cactodera chenopodiae n. sp., parasitizing common lambsquarter, Chenopodium album L., is described from native vegetation in Liaoning, China. Cactodera chenopodiae n. sp. has a circumfenestrate pattern typical of the genus and is morphologically similar to C. cacti Krall Krall, 1978. However, in the new species, females and cysts show a larger L/W ratio whereas second-stage juveniles (J2s) have a longer hyaline region. The new species is also morphologically similar to C. milleri Graney Bird, 1990, but the J2s differ by a larger b ratio and longer tail. Based on DNA sequences of the 28S and ITS rRNA, C. chenopodiae n. sp. comes close to C. estonica Krall Krall, 1978, although it is distinct from the latter with respect to the presence of a punctate eggshell and larger b ratio in the J2s. Although morphometric comparisons with additional Cactodera species show the overlapping of diagnostic morphological characters, our phylogenetic analyses based on both rRNA genes support C. chenopodiae n. sp. as a unique lineage.

    2011-01-01

    Background With the medical reform, the function of community health centres emerged to be more important recently in China. However, the health service capabilities were tremendously different between metropolitan cities and small cities. This study aims to clarify the level of job satisfaction of Chinese community health workers between a metropolitan (Shenyang) and a small city (Benxi) in Liaoning province and explore its associated factors. Methods A cross-sectional survey was conducted from December 2009 to February 2010. A multi-stage sample was used and a total of 2,100 Chinese community health workers from the two cities completed self-administered questionnaire pertaining to job satisfaction indicated by Minnesota Satisfaction Questionnaire (MSQ), demographic characteristic and working situations, stress and job burnout. The effective response rate was 80.7%. Hierarchical regression analysis was performed to explore the related factors. All data analyses for the two cities were performed separately. Results The averages of overall job satisfaction score of Chinese community health workers were 67.17 in Shenyang and 69.95 in Benxi. Intrinsic job satisfaction and extrinsic job satisfaction among Chinese community health workers were significantly different between Shenyang and Benxi (p job satisfactions, respectively. In Benxi, the fourth model explained 48%, 52% of the variance of intrinsic and extrinsic job satisfactions, respectively. Three significant predictors of intrinsic and extrinsic job satisfactions for the two cities were the two dimensions (social support and decision latitude) of stress and cynicism of burnout. Conclusion From this study, the job satisfaction among Chinese community health workers in the two cities enjoyed a moderate level of job satisfactions, which represented they are not fully satisfied with their jobs. Community health workers in Shenyang had lower job satisfaction as compared to those in Benxi. This study strengthened the

  16. The False Panacea of City Charters? A Political Perspective on the Case of Toronto

    Directory of Open Access Journals (Sweden)

    Andrew Sancton

    2016-01-01

    Full Text Available Toronto is unlike any other city, as its local boosters will not hesitate to point out. That was the basis, after all, of the “charter movement” that demanded special rights for a mega-city that the movement’s backers insisted was so vital that it even warranted a status similar to that of an entire province. Their efforts culminated in the province’s passage in 2006 of the City of Toronto Act, which appeared on its face to grant the metropolis the power it believed it required and merited. In reality, the Ontario government may have actually set Toronto back, leaving it more at the mercy of provincial power than other smaller municipalities. The few additional taxation powers that were granted by the ostensible Toronto “charter” — the City of Toronto Act — are, in reality, still overseen by the province, which retains the right to limit those revenue tools if it considers it “desirable in the provincial interest to do so.” But while Toronto may have been given just a small number of revenue tools, which it has used only sparingly, and the use of those tools is ultimately decided by Queen’s Park, their very existence has given the province licence to sidestep the city’s calls for more funding. The provincial Liberals have, in the past, insisted that Toronto make use of its own taxes before it demands more provincial funds. Meanwhile, the City of Toronto Act did nothing to curtail the power of the Ontario Municipal Board (OMB. Because municipal zoning decisions made in Toronto can be appealed to the OMB, which can substitute its own idea of “good planning” for elected local government, the City of Toronto is ultimately left with limited control over its planning decisions. In sum, virtually none of the desires that Toronto expected would be served by a city charter have been fulfilled. Quite the opposite, it would appear that the dreams once imagined by charter-city proponents have been snuffed out, and there is no

    Trichomonas vaginalis (TV) is a protozoan parasite that causes trichomoniasis, a sexually transmitted disease, worldwide. In this study, we investigated the prevalence and genetic characterization of T. vaginalis and contrasted the most prevalent strains of T. vaginalis isolated from Xinxiang City, Henan Province, China. In Xinxiang from September 2015 to September 2017, a total of 267 (1.64%, 95% confidence interval, CI: 1.45-1.85) clinical T. vaginalis-positive samples from vaginal secretions were observed by wet mount microscopy from 16,294 women with some clinical symptoms of trichomoniasis. We found that trichomoniasis frequently occurred in the 21- to 40-year-old age group and in winter. After the 267 clinical T. vaginalis positive samples were cultured, 68 isolates of T. vaginalis were harvested and identified as genotype E (58.82%), H (17.65%), mixed 1 (17.65%) and mixed 2 (5.88%) using a sensitive and reliable polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) typing method on the actin gene. The phylogenetic diversity analysis showed that the genotype E samples fell within a separate clade compared to the other T. vaginalis isolates, while the samples of the genotype H separated into two clades. Our results demonstrate a notable gene polymorphism of clinical isolates from the targeted population and provide insight into the performance of these genetic markers in the molecular epidemiology of trichomoniasis. However, further studies are needed to clarify the association between a certain genotype and the pathogenicity of T. vaginalis.

    With currently China's farmland transformation for non-agricultural advancement is speeding up, such disadvantages as low standard and simplified mode of compensation obviously appears in our land expropriation (requisition) system. And land expropriation (requisition) price has been distorted seriously, which has caused a series of social problems aroused more attention from many fields. It's high time to establish new criteria of land compensation. This paper presents a new method to analyze the compensation standard of cultivated-land Expropriation and requisition respectively through defining and normalize the connotation of tenure system and relevant rights of cultivated land in China, and to explore the value composition of rights over cultivated land. Methods of logic analysis, comparison and empirical analysis were applied. The results show that the tenure system of cultivated land is composed of five parts: natural productive price, social security price, social stabilization price, ecological security price and development right price. The values of all these rights vary under different socio-economic conditions, and they have to be embodied gradually in the process of land Expropriation and requisition. Moreover, the new proposed methodology has been applied to a case study of paddy lands located in Nanyang City, Henan Province in order to demonstrate its goodness. From the results of this work we can conclude that the approach proposed stands out as a good alternative to current compensation standard of cultivated-land Expropriation (requisition).

    It is generally believed that there is an inverse relationship between population growth and vegetation cover. However, reports about vegetation protection and reforestation around the World have been continuously increasing in recent decades, which seems to indicate that this relationship may not be true. In this paper, we have taken 21 cities in Guangdong Province, China as the study area to test the long-term relationship between population growth and vegetation cover, using an AVHRR NDVI data set and the panel cointegrated regression method. The results show that there is a long-term inverted N-shaped curve relationship between population growth and vegetation cover in the region where there are frequent human activities and the influence of climate change on vegetation cover changes is relatively small. The two turning points of the inverted N-shaped curve for the case of Guangdong Province correspond to 2,200 persons · km(-2) and 3,820 persons · km(-2), and they can provide a reference range for similar regions of the World. It also states that the population urbanization may have a negative impact on the vegetation cover at the early stage, but have a positive impact at the later stage. In addition, the Panel Error Correction Model (PECM) is used to investigate the causality direction between population growth and vegetation cover. The results show that not only will the consuming destruction effect and planting construction effect induced by the population growth have a great impact on vegetation cover changes, but vegetation cover changes in turn will also affect the population growth in the long term.

    Full Text Available Social Stratification can be described as “differentiation of a certain population hierarchically, namely, classes being located one after another in social terms”. As at present time, in the past periods as well, one of the most important factors that affected the social stratification was the posts of the persons, that is to say, the occupations and economic power they had. In Ottoman State, human communities living in cities were composed of different groups in general. It has been possible to arrange human groups especially with respect to their jobs or their economical situations and educational positions. As in the other Ottoman cities, in the city and the province of Diyarbakır, those groups constituted the social stratums. In this study, about social stratification in Diyarbakir city and state are given. Family and women issues form the main core of these layers are discussed in detail. Of the pillars of society throughout history and despite being one of the cornerstones of the nuclear family; this aspect of women in various cultures and periods or have been denied or ignored by hovering, has been reduced to a passive position.

    Full Text Available As one of the areas where typical late Archean crust is exposed in the Eastern Block of the North China Craton, the northern Laioning Complex consists principally of tonalitic-trondhjemitic-granodioritic (TTG gneisses, massive granitoids and supracrustal rocks. The supracrustal rocks, named the Qingyuan Group, consist of interbedded amphibolite, hornblende granulite, biotite granulite and BIF. Petrological evidence indicates that the amphibolites experienced the early prograde (M1, peak (M2 and post-peak (M3 metamorphism. The early prograde assemblage (M1 is preserved as mineral inclusions, represented by actinotite + hornblende + plagioclase + epidote + quartz + sphene, within garnet porphyroblasts. The peak assemblage (M2 is indicated by garnet + clinopyroxene + hornblende + plagioclase + quartz + ilmenite, which occur as major mineral phases in the rock. The post-peak assemblage (M3 is characterized by the garnet + quartz symplectite. The P–T pseudosections in the NCFMASHTO system constructed by using THERMOCALC define the P–T conditions of M1, M2 and M3 at 490–550 °C/<4.5 kbar, 780–810 °C/7.65–8.40 kbar and 630–670 °C/8.15–9.40 kbar, respectively. As a result, an anticlockwise P–T path involving isobaric cooling is inferred for the metamorphic evolution of the amphibolites. Such a P–T path suggests that the late Archean metamorphism of the northern Liaoning Complex was related to the intrusion and underplating of mantle-derived magmas. The underplating of voluminous mantle-derived magmas leading to metamorphism with an anticlockwise P–T path involving isobaric cooling may have occurred in continental magmatic arc regions, above hot spots driven by mantle plumes, or in continental rift environments. A mantle plume model is favored because this model can reasonably interpret many other geological features of late Archean basement rocks from the northern Liaoning Complex in the Eastern Block of

    Full Text Available The distribution of goods in urban areas, together with private traffic flows, are among the main sources of energy consumption, air pollution and noise. As a consequence, in the 2000s, several EU cities started to implement logistical solutions for the sustainable city. In this context, this study addresses the implementation of a new eco-logistic system, which serves multiple adjacent cities by using electric vehicles to deliver goods of any type within their urban areas. This paper describes the results of a project developed in the province of Vicenza (northern Italy and covering the main cities (Bassano del Grappa, Thiene, Schio and Valdagno in the foothills (the so-called Pedemontana Veneta zone. The eco-logistic system aims to cover the last 50 miles of distribution (typical area of an Italian province with a centralised platform that performs green deliveries with electric vehicles from/to the downtown areas. A preliminary and extensive “on field” analysis by means of door-to-door questionnaires was conducted to identify the performance required by the eco-logistic system. Therefore, the design of such a distribution system is performed to assess and define the conditions that make this solution profitable from both the economic and the environmental perspective.

    Full Text Available Smart cities have been recently recognized as the most pleasing and attractive places to live in; due to this, both scholars and policy-makers pay close attention to this topic. Specifically, urban “smartness” has been identified by plenty of characteristics that can be grouped into six dimensions (Giffinger et al. 2007: smart Economy (competitiveness, smart People (social and human capital, smart Governance (participation, smart Mobility (both ICTs and transport, smart Environment (natural resources, and smart Living (quality of life. According to this analytical framework, in the present paper the relation between urban attractiveness and the “smart” characteristics has been investigated in the 103 Italian NUTS3 province capitals in the year 2011. To this aim, a descriptive statistics has been followed by a regression analysis (OLS, where the dependent variable measuring the urban attractiveness has been proxied by housing market prices. Besides, a Cluster Analysis (CA has been developed in order to find differences and commonalities among the province capitals.The OLS results indicate that living, people and economy are the key drivers for achieving a better urban attractiveness. Environment, instead, keeps on playing a minor role. Besides, the CA groups the province capitals a

Noted that the rapid increase in the number of city residents not only contributed to the expansion of urban processes, but also significantly reflected in the increase in the scale of manifestations of deviance. Focuses on the fact that such reverse the impact of migration processes as material poverty and poverty were the reason for the growth in the cities the number of robberies, theft, begging, prostitution, suicide or violent deaths. According to the observations of the author considerable influence on the distribution of social «diseases» of urban society province had the moral degradation of the population ­ the shamelessness and thirst for easy money, disrespect for the law and unwillingness to work. All this caused the deterioration of the crime situation in the cities, the growth of alcoholism, prostitution, the number of suicides and other, less dangerous manifestations of deviant behavior, which considerably decreased the indicators of living conditions in the province. And although charitable activities and conduct of moral and educational talks, shelters, lodging houses and houses of diligence somewhat softened the situation, they could not solve the problems of social contrasts the modern city of the region.

    To analyze the status and characteristics of dental manpower in the center for disease controls (CDC) in Sichuan Province and to provide more evidence for strengthening the oral healthcare workforce in the CDC system. A mass survey on dental manpower was made in CDCs in Sichuan Province through questionnaire investigation. Data were collected and entered with the Epidemiological Dynamic Data Collection (EDDC) platform and analyzed with SPSS 13.0 software. Sichuan Province had 0.15 hospitals providing oral health services and 0.38 dentists on average per 10,000 people. About 65.53% (135/206) of the CDCs had one department responsible for the oral health service. However, oral health care personnel comprised only 2.23% (237/10,624) of the personnel of the whole CDC system. About 64.67% (119/184) of county CDCs and 47.62% (10/21) of city CDCs knew well the dental health status of local residents. Less than 5% of the CDCs used the data and assisted in the policy making of public health administrators. The dental care personal deficit exists in the CDC system in Sichuan Province. The distribution and composition of dental manpower are not reasonable. The oral health service ability of CDCs in Sichuan Province should be strengthened and improved.

    Shandong province is located on the east coast of China and has a coastline of about 3100 km. There are only a few tsunami events recorded in the history of Shandong Province, but the tsunami hazard assessment is still necessary as the rapid economic development and increasing population of this area. The objective of this study was to evaluate the potential danger posed by tsunamis for Shandong Province. The numerical simulation method was adopted to assess the tsunami hazard for coastal areas of Shandong Province. The Cornell multi-grid coupled tsunami numerical model (COMCOT) was used and its efficacy was verified by comparison with three historical tsunami events. The simulated maximum tsunami wave height agreed well with the observational data. Based on previous studies and statistical analyses, multiple earthquake scenarios in eight seismic zones were designed, the magnitudes of which were set as the potential maximum values. Then, the tsunamis they induced were simulated using the COMCOT model to investigate their impact on the coastal areas of Shandong Province. The numerical results showed that the maximum tsunami wave height, which was caused by the earthquake scenario located in the sea area of the Mariana Islands, could reach up to 1.39 m off the eastern coast of Weihai city. The tsunamis from the seismic zones of the Bohai Sea, Okinawa Trough, and Manila Trench could also reach heights of >1 m in some areas, meaning that earthquakes in these zones should not be ignored. The inundation hazard was distributed primarily in some northern coastal areas near Yantai and southeastern coastal areas of Shandong Peninsula. When considering both the magnitude and arrival time of tsunamis, it is suggested that greater attention be paid to earthquakes that occur in the Bohai Sea. In conclusion, the tsunami hazard facing the coastal area of Shandong Province is not very serious; however, disasters could occur if such events coincided with spring tides or other

    Green spaces which are one of the most important public spaces in urban design have an important role on qualified daily urban life. People escape from intense work pressure and traffic jam of metropoles to those urban green areas to take a breath even they cover a small size. In time, people’s expectations from green spaces as functional and quantitative needs are changing. This change occurs due to increasing population and as the character of the urban life. This study examines the functional use and quantitative change of urban green spaces of Kırklareli Province from past to present. Kırklareli is a border city to Bulgaria which is located in north-west part of Turkey and this gives a transitional and a multicultural character to the city. The population is about 67360. In the course of time; green space needs have increased by the increasing population. In addition to this, green spaces’ functional use change has been identified. According to the results of the study; from the aspect of the green space standards, Kırklareli found above standards with 17.5 m2 per capita, but on the other hand, sport and playground areas found insufficient. The Oldest and the newest city plans of Kırklareli (1940s and 2012s cadastral plans) have been compared and site surveys implemented as the methodology. In site survey, current green spaces’ functional uses as sport or playground are observed and determined and also current quantitative measure of the green spaces are verified. Urban green spaces in Kırklareli Province evaluated through considering world’s most populated urban green space standards and Turkey’s standards. This study utilizes to compose a substructure of the urban green space. Determined deficiencies and inadequacies of green spaces and functional needs in this study, can guide to further studies and implementations of Kırklareli Municipality.

    Pollution and health risks generated by improper solid waste management are important issues concerning environmental management in developing countries. In most cities, the use of open dumps is common for the disposal of wastes, resulting in soil and water resource contamination by leachate in addition to odors and fires. Solid waste management infrastructure and services in developing countries are far from achieving basic standards in terms of hygiene and efficient collection and disposal. This paper presents an overview of current municipal solid waste management in Rasht city, Gilan Province, Iran, and provides recommendations for system improvement. The collected data of different MSW functional elements were based on data from questionnaires, visual observations of the authors, available reports and several interviews and meetings with responsible persons. Due to an increase in population and changes in lifestyle, the quantity and quality of MSW in Rasht city has changed. Lack of resources, infrastructure, suitable planning, leadership, and public awareness are the main challenges of MSW management of Rasht city. However, the present situation of solid waste management in this city, which generates more than 400 tons/d, has been improved since the establishment of an organization responsible only for solid waste management. Source separation of wastes and construction of a composting plant are the two main activities of the Rasht Municipality in recent years

    Objective: To investigate the understanding of infectious diseases, their prevention, and control, and the factors influencing this literacy among urban and rural residents of Zhejiang Province. Methods: In November- December 2014, a multistage stratified cluster sampling questionnaire was administered at study sites in eight districts of Zhejiang province: Hangzhou city Gongshu district, Hangzhou city Chun'an county, Wenzhou city Cangnan county, Dongyang city, Jiaxing city Jiashan county, Zhoushan city Putuo district, Linhai city, Lishui city Jinyun county. The inclusion criteria were: 15-60 years old, living locally for more than six continuous months, and no mental illness. The exclusion criteria were: foreigner residing locally, resident of Hong Kong, Macau, or Taiwan, or unable to communicate through speech or writing. In this study, 4 091 questionnaires were distributed, and 4 020 valid questionnaires were returned(98.26%). Health literacy regarding infectious diseases was measured at five levels: knowledge, skills, behaviors, access to information, and understanding of the prevention of infectious diseases. A total score was calculated for each questionnaire, and a total score of ≥80 was deemed to indicate an understanding of the prevention of infectious diseases. A χ 2 test was used to compare the levels of health literacy in different populations with single-factor analyses, and a multivariate unconditional logistic regression model was used to analyze the factors affecting infectious diseases prevention and treatment literacy levels. Results: Of the 4 020 respondents(aged(43.84 ± 10.28)years), 1 964 were male(48.86%)and 2 056 were female(51.14%). In the total surveyed population, 15.17%( n =610)understood the prevention of infectious diseases, 294 were male(14.97%)and 316 were female(15.37%)(χ 2 =2.48, P =0.115).

    Full Text Available Ascaris lumbricoides is the most common intestinal parasite in the world. Various studies has indicated the high prevalence of this parasite in Iran, specially in the west parts of Iran. The epidemiological study of intestinal parasitic infection is prerequisite for planning of control programs. The Hamadan province is one of the most tourist attraction regions of Iran and providing a safe environment for travelers is the main aim of regional authorities. A mass chemotherapy for Ascariasis performed in rural areas of Hamadan province for a five years period but, no any intervention was done for control of this parasite in the Hamadan city. Therefore, an epidemiological study of Ascariasis in this town was necessary. A cross sectional study carried out by cluster random sampling in Hamadan and 580 stool specimens collected from different parts of city. The stools were examined by formalin ether concentration technique for ova and parasites and intensity of infection was determined by quantitative modified Stoll method. Mean infection rate of Ascariasis was 19.5%. The Farhangian suburb (northern part had higher infection rate than other parts(28.5% and central parts of city showed lower infection rate(12.7%. The highest infection rate were found in the 31-40 years age group (33.8% and in the females(23.9%.In view of intensity, 59.3% of infections were moderate and 48.3% had low intensity. No any high intensity were found. Mean egg per gram(epg were 7129 and 48.7% of eggs were infertile. This study indicated that , prevalence of Ascaris in Hamadan city is considerable at present and a suitable intervention, like health education and selective chemotherapy is necessary to decrease the infection.

    The carbon intensity of economic activity, or CO 2 emissions per unit GDP, is a key indicator of the climate impacts of a given activity, business, or region. Although it is well-known that the carbon intensity of countries varies widely according to their level of economic development and dominant industries, few studies have assessed disparities in carbon intensity at the level of cities due to limited availability of data. Here, we present a detailed new inventory of emissions for 337 Chinese cities (every city in mainland China including 333 prefecture-level divisions and 4 province-level cities, Beijing, Tianjin, Shanghai, and Chongqing) in 2013, which we use to evaluate differences of carbon intensity between cities and the causes of those differences. We find that cities' average carbon intensity is 0.84 kg of CO 2 per dollar of gross domestic product (kgCO 2 per $GDP), but individual cities span a large range: from 0.09 to 7.86 kgCO 2 per $GDP (coefficient of variation of 25%). Further analysis of economic and technological drivers of variations in cities' carbon intensity reveals that the differences are largely due to disparities in cities' economic structure that can in turn be traced to past investment-led growth. These patterns suggest that "carbon lock-in" via socio-economic and infrastructural inertia may slow China's efforts to reduce emissions from activities in urban areas. Policy instruments targeted to accelerate the transition of urban economies from investment-led to consumption-led growth may thus be crucial to China meeting both its economic and climate targets.

    Full Text Available In the city, all people see. In the city, all people are seen. The look and its related questions – what to see, as to see, the interpretation of what is seen – Is one of the central questions of the urban space since century XIX, with the growth of the cities and the phenomenon of the multitude. The look becomes, therefore, crucial to this urban man, whom it looks to recognize in this another one – the stranger – the signals of friendship or danger. This importance of the look in the city is investigated in this essay through two films: Rear window, Alfred Hitchcock (1954, and Caché, Michael Haneke (2005. In the first movie, the personages look the city. In the other, they are seen by this city. In the two films, we have the extremities of the same process: the social life transformed into spectacle. And the cinema, playing one of its main functions: the construction of representations of the human lives in the city.

    Analysis with some habitat indexes of different succession stage, this paper quantitatively measured the degradation degree of degraded ecosystems in this region. The results showed that the average dissimilarities between natural Quercus forest, natural Chinese pine (Pinus tabulaeformis) forest and Populus-Quercus forest in Nanliuzhangzi forestry centre and Chinese pine plantations in Niuheliang region and Qitian forestry centre were 0.655, 0.665, 2.029 and 3.919, respectively, and as a whole, the dissimilarities represented the places of the forests in the process of ecosystem succession/degradation. It was also showed that most habitats were degraded to the stage between shrubbery and pioneer arbor forest, and closer to the succession stage of pioneer arbor forest. Some suggestions were made for the management of the existing plantation and the construction of mixed forest, e.g., to increase the proportion of shrubbery and pioneer arbor species, especially that of nitrogen fixation tree species. The plant species list of several main vegetation types in western Liaoning we offered could provide scientific reference for the vegetation restoration and the management of pure Chinese pine plantation in this region.

    According to the report of the World Health Organization (WHO) on the list of 50 cities with the most polluted air in Europe as many as 33 are located in Poland. All the cities that are on the list exceed the maximum concentration of dust recommended by WHO at least three times. In the Lubuskie Province there is a very serious problem of maintaining good air quality. The air in Poland is among the most polluted in the European Union and this also applies to less-industrialized areas, such as Lubuskie, where the concentration levels of substances hazardous to human health and the environment are recorded as exceeded. One of the main factors affecting the poor air quality in the region is road transport. It is not just a problem near roads with heavy traffic, but also applies to the cities, where there is a large movement of cars, which are often old and do not meet current environmental standards. This article aims to identify the main sources of low emission from road transport and identify potential solutions to help reduce emission from this sector. The actions aimed at limiting low emission from road transport can bring a significant positive ecological effect. The aim of this article is to review one of the main sources of low emission in the province of Lubuskie, which is transportation. Moreover, the authors of the paper indicate the main problems associated with the emission coming from road transport and describe the possibilities for opportunities to reduce pollution from this sector. In addition, the article presents the three-scenario simulation of annual emissions from passenger cars that could take place in 2020.

    to estimate the spatial distribution of risk, in order to assess its correlation to environmental pollution exposure around the large production facilities located in the Taranto area, and to identify high risk areas not previously reported. Italy, Taranto province (581,508 inhabitants). incidence data in 29 municipalities of the Taranto province were extracted from the Jonico Salentino Cancer Registry (RTJS) for the following cancer sites: lung (ICDX C33-C34); pleura, pleuric mesothelioma (ICDX C45.0); bladder, malignancies only (ICDX C67); brain (ICDX C70-72); non-Hodgkin lymphoma (ICDX C82-85, C96); leukaemia (ICDX C91-5). Age standardized incidence rates for the whole province were computed. High-level risk areas were classified using a Poisson model, computing area-specific p-values associated to the null hypothesis of no increased risk (i.e. relative risk equal to 1). A hierarchical spatial Bayesian model was estimated to strengthen results: specifically two additional variance components, accounting for relative risk spatial autocorrelation and excess heterogeneity respectively, were considered in the model specification. Bayesian mapping of disease incidence allows for the drawing of regularized (smoothed) maps. To adjust for the effect of socio-economic deprivation, a five-variable index was introduced into the model as an ecological covariate. an increased risk of lung, pleura and bladder cancer was observed among male residents in the city of Taranto (respectively: SIR 1.24, p-value sexe risk (especially among males) of lung, pleura and bladder cancer is likely related to the chemical pollutants and asbestos, due to the presence of many industries and shipyards in the city of Taranto.

    To investigate the contamination of aflatoxins in food in Shaanxi Province, and provide the basic data of dietary intakes of aflatoxins for food safety assessment. In year 2012- 2015, 1007 food samples of eight kinds of food including grains, beans, vegetable oil, nuts and seeds, condiment, liquor, tea and infants' food were collected randomly from ten cities, and determined with UPLC. 1007 samples were detected aflatoxins and the total detection rate was 10. 7%. The detection range was 0. 070- 323 μg / kg, with the mean value of 2. 34 μg / kg. Among all food samples, only peanut products were more seriously polluted than other kinds of foods. The overall level of aflatoxins contamination in market food is low, but peanut products might be the contaminated foods with aflatoxins in Shaanxi Province, and should be given more attention.

    Full Text Available City parks, important environments built for physical activity, play critical roles in preventing chronic diseases and promoting public health. We used five commonly used park indicators to investigate the spatiotemporal trend of city parks in mainland China between 1981 and 2014 at three scales: national, provincial and city class. City parks in China increased significantly with a turning point occurring around the year 2000. Up until the end of 2014, there were 13,074 city parks totaling 367,962 ha with 0.29 parks per 10,000 residents, 8.26 m2 of park per capita and 2.00% of parkland as a percentage of urban area. However, there is still a large gap compared to the established American and Japanese city park systems, and only 5.4% of people aged above 20 access city parks for physical activity. The low number of parks per 10,000 residents brings up the issue of the accessibility to physical activity areas that public parks provide. The concern of spatial disparity, also apparent for all five city park indicators, differed strongly at provincial and city class scales. The southern and eastern coastal provinces of Guangdong, Fujian, Zhejiang and Shandong have abundant city park resources. At the scale of the city classes, mega-city II had the highest of the three ratio indicators and the large city class had the lowest. On one hand, the leading province Guangdong and its mega-cities Shenzhen and Dongguan had park indicators comparable to the United States and Japan. On the other hand, there were still five cities with no city parks and many cities with extremely low park indicators. In China, few cities have realized the importance of city parks for the promotion of leisure time physical activity. It is urgent that state and city park laws or guidelines are passed that can serve as baselines for planning a park system and determining a minimum standard for city parks with free, accessible and safe physical activity areas and sports facilities.

    Full Text Available The aim of this study was to evaluate the contagious diseases surveillance studies after the flood disaster between 31.10.2006 and 02.11.2006 in Batman province. After flood disaster, there had been taken some measures about water sanitation, immunization and organization of the health services and the public education issues.Super chlorination procedure had been applied to drinking water in the city center. The free chlorine levels of 890 water specimens from different areas of the province had been measured and the results were between 0.3 to 0.8 ppm. A random 359 specimens were tested biologically and chemically and they have been found eligible to use. Health units of the municipality had been provided with adequate tetanus vaccine in order to inoculate the persons who had been wounded. Children without adequate childhood vaccinations and immunizations were encouraged to complete their vaccinations in the closest dispensaries. A structural questionnaire had been applied with the aim of collecting data about potential contagious diseases in the area. For the following two weeks after the disaster, 0.6 % of the residents were observed to have gastroenteritis. However, the EPI Curve of the gastroenteritis cases do not show a potential epidemic in the province. Active surveillance system which applies by visiting households is important for taking essential preventive measures; besides, early detecting of potential contagious diseases.

    Productivity of oil and gas and their high cost benefit in matters than combustion, in one hand and their problem of environmental pollution when they are burnt, on the other hand attracted the decision markers in Iran to consider the wind energy as a good alternative for energy resources . It is especially important because of the existence of regions with high potential for wind energy in Iran. The Kurdestan province is one of the windy places in Iran that has not been considered for wind energy yet. In this paper, the general characteristics of the different kinds of winds which are blown throughout the year in Kurdestan province are considered firstly. Then by using the information from the stations in the sixth major cities in the province, the wind characteristics including power, direction, intensity and probability at different months of the year, are considered. The statistical studies show that Bijar, Zarine Obatoo, Ghorveh, Sanandaj and Marivan have the most wind energy potential, and Bijar and Ghorveh are the best places to install the wind turbine. for all of the above regions, the maximum of the wind average speed and powe are obtained in March, April. May, and the minimum of the average wind speed occurs in December. Bijar, Ghorveh and Zarine Obatoo have high average wind speed and its recommended to search for best places in these regions for the wind turbine sites

    Psychiatry has been considered as one of the most stressful medical specialities, and psychiatrists are likely to experience impaired health-related quality of life (HRQOL). However, few studies are available in regard to related factors of HRQOL among psychiatrists in China. This study aims to evaluate the condition of HRQOL of psychiatrists and explore its predictive factors, especially the effects of occupational stress and psychological capital. A cross-sectional, multicenter survey was conducted among psychiatrists from different regions of Liaoning province, China, during August 2013-April 2014. Self-administrated questionnaires including the 36-item Short-Form Health Survey (SF-36), the Chinese version Psychological Capital Questionnaire, effort-reward-imbalance (ERI) scale and participants' basic characteristics were distributed to 500 psychiatrists from 10 psychiatric hospitals of 8 major cities in Liaoning province. Overall, 373 psychiatrists became our final research objects. Hierarchical multiple regression analysis (HMR) was performed to explore the predictors of psychiatrists' HRQOL. The mean (SD) scores of PCS and MCS among psychiatrists were 79.78 (16.55) and 71.50 (19.24) respectively. The mean (SD) of ERR were 0.777 (0.493), and 89 (23.9%) had ERR scores above 1 (ERR > 1). Hierarchical multiple regression analysis showed that, psychiatrists' basic characteristics that significant correlated with PCS and MCS were educational level, turnover intention, and exercise; age, weekly working hours were associated with MCS; psychiatrists' experienced occupational stress (both ERR and overcommitment), and PsyCap were significant predictors for PCS and MCS. Chinese psychiatrists experienced relatively good physical QOL but impaired mental QOL, and they experienced high level of occupational stress. For the sake of psychiatrists' HRQOL, the reduction of occupational stress should be implemented. The enhancement of PsyCap could be a new intervention

    One important aspect of disaster mitigation planning is hazard mapping. Hazard mapping can provide spatial information on the distribution of locations that are threatened by disaster. Semarang City as the capital of Central Java Province is one of the cities with high natural disaster intensity. Frequent natural disasters Semarang city is tidal flood, floods, landslides, and droughts. Therefore, Semarang City needs spatial information by doing multi hazard mapping to support disaster mitigation planning in Semarang City. Multi Hazards map modelling can be derived from parameters such as slope maps, rainfall, land use, and soil types. This modelling is done by using GIS method with scoring and overlay technique. However, the accuracy of modelling would be better if the GIS method is combined with Fuzzy Logic techniques to provide a good classification in determining disaster threats. The Fuzzy-GIS method will build a multi hazards map of Semarang city can deliver results with good accuracy and with appropriate threat class spread so as to provide disaster information for disaster mitigation planning of Semarang city. from the multi-hazard modelling using GIS-Fuzzy can be known type of membership that has a good accuracy is the type of membership Gauss with RMSE of 0.404 the smallest of the other membership and VAF value of 72.909% of the largest of the other membership.

    The Alto Paraguay Province is located at the border of the State of Mato Grosso do Sul and Paraguay, between the coordinates 21 deg 10 ' to 23 deg 25 ' of Southern latitude and 57 deg 10 ' to 58 deg 00 ' , having the city of Porto Murtinho as the main reference point. The geotectonic domain of the area is governed by the precambric units of the Southern extreme of the Amazonic craton which developed a long and accentuated activity, giving rise to folds and important faults, that in several cases seem to have exerted an effective control of the magmatic manifestations. Radiometric data indicate that the emplacement of the syenitic bodies took place in the Permo-Triassic period, with a major incidence in the interval 260-240 Ma, representing thus, an important phase of alkaline magmatic affinity associated to the Parana Basin which is believed is to be unique, since the other known areas (Central, Amambay and Rio Apa Provinces, Paraguay, Velasco Province, Bolivia) are considerably younger (140-120 Ma). Syenitic rocks from the Alto Paraguay Province show wide variation in the ratio 87 Sr/ 86 Sr (0.703361 - 0.707734). Excluding the Cerro Boggiani rocks (0.703837-0.707734), values for the nepheline syenites (0.703361-0.703672) general lower than those of the other syenites types. Alkaline syenites cover the interval 0.703510- 0.703872, while quartz syenites and syenogranites are 0.704562 and 0.707076, respectively. geologic evidence, in addition to petrographic, geochemical and isotopic (Sr) data, suggest that the syenitic rocks have been derived from an unique mantelic parental liquid, by fractional crystallization and assimilation processes, which are assumed to be occurred during the emplacement of the magma in the crust.

    2016-11-01

    Full Text Available During the past 30 year of economic growth, China has also accumulated a huge environmental pollution debt. China’s government attempts to use a variety of means, including tax instruments to control environmental pollution. After nine years of repeated debates, the State Council Legislative Affairs Office released the Environmental Protection Tax Law (Draft in June 2015. As China’s first environmental tax law, whether this conservative “Environmental Fee to Tax (EFT” reform could improve the environment has generated controversy. In this paper, we seek insights to this controversial issue using the machine learning approach, a powerful tool for environmental policy assessment. We take Hubei Province, the first pilot area as a case of EFT, and analyze the institutional incentive, behavior transformation and emission intensity reduction performance. Twelve pilot cities located in Hubei Province were selected to estimate the effect of the reform by using synthetic control and a rapid developing machine learning method for policy evaluation. We find that the EFT reform can promote emission intensity reduction. Especially, relative to comparable synthetic cities in the absence of the reform, the average annual emission intensity of Sulfur Dioxide (SO2 in the pilot cities dropped by 0.13 ton/million Yuan with a reduction rate of 10%–32%. Our findings also show that the impact of environmental tax reform varies across cities due to the administrative level and economic development. The results of our study are also supported by enterprise interviews. The EFT improves the overall environmental costs, and encourages enterprises to reduce emissions pollution. These results provide valuable experience and policy implications for the implementation of China’s Environmental Protection Tax Law.

    Full Text Available During the Visigothic period, the city of Arcavica was one of the three bishoprics placed in the present province of Cuenca, together with those of Segobriga and Valeria. With the exception of the signatures of Arcavica's prelates on Council minutes there is no direct mention of the city in the sources available. Even so, the importance of its archaeological site is reflected in the numerous remains found on the hill where the Roman-Celtiberian city of Ercavica used to lay. However important the city itself may be, archaeological research in this area is mainly focused on the problem of locating the Servitanus Monastery founded by the North-African abbot Donatus and his seventy monks. Its location in Arcavica, as the authors of the present article defend, is essential to interpret the remains found in this site and to understand a significant part of Spain's history that takes place during the crucial years of Leovigild's and Recared's reigns.

    Ecosystems and their components provide a lot of benefits for the welfare of human beings. Coupled with increasing socioeconomic development, most of the rapidly developing and transitional countries and regions have been experiencing dramatic land use changes. This has resulted in a large amount of forestland, grassland, and wetland being occupied as residential and industrial land or reclaimed for arable land, which in turn results in a sharp deterioration of ecosystem services around the world. Shandong Province, an economically powerful province of China, was chosen as a case study in order to capture the impact of socioeconomic development on ecosystem services. By way of the study, land uses and their changes were categorized between 1980 and 2006, and the ecosystem services capital and changes of 111 counties of Shandong Province in different phases were evaluated, as well as the total ecosystem services capital, followed by the zoning of ecosystem services function region of Shandong Province. We found that the counties in mountainous areas and wetlands, where generally the prefectural-level cities are located with a rapid socioeconomic development, experienced a successive deterioration of ecosystem services especially during the 2000s. Finally, three conservation strategies for managing and improving ecosystem services were proposed and discussed with the aim of achieving coordinate and sustainable development of the socioeconomy, environment, and ecosystems not only in Shandong Province but also in other provinces of China, as well as in other developing and transitional countries and regions.

    The purpose of this study was to classify determinants of cost increases into two categories, negotiable factors and non-negotiable factors, in order to identify the determinants of health care expenditure increases and to clarify the contribution of associated factors selected based on a literature review. The data in this analysis was from the statistical yearbooks of National Health Insurance Service, the Economic Index from Statistics Korea and regional statistical yearbooks. The unit of analysis was the annual growth rate of variables of 16 cities and provinces from 2003 to 2010. First, multiple regression was used to identify the determinants of health care expenditures. We then used hierarchical multiple regression to calculate the contribution of associated factors. The changes of coefficients (R(2)) of predictors, which were entered into this analysis step by step based on the empirical evidence of the investigator could explain the contribution of predictors to increased medical cost. Health spending was mainly associated with the proportion of the elderly population, but the Medicare Economic Index (MEI) showed an inverse association. The contribution of predictors was as follows: the proportion of elderly in the population (22.4%), gross domestic product (GDP) per capita (4.5%), MEI (-12%), and other predictors (less than 1%). As Baby Boomers enter retirement, an increasing proportion of the population aged 65 and over and the GDP will continue to increase, thus accelerating the inflation of health care expenditures and precipitating a crisis in the health insurance system. Policy makers should consider providing comprehensive health services by an accountable care organization to achieve cost savings while ensuring high-quality care.

    Rabies is a global fatal infectious viral disease that is characterized by a high mortality after onset of clinical symptoms. Recently, there has been an increase in the incidence of rabies in China. The aim of this study was to investigate the incidence of human rabies and characterize the rabies virus nucleoprotein gene in dogs sampled from Fujian Province, Southeast China from 2002 to 2012. Data pertaining to human rabies cases in Fujian Province during the period from 2002 through 2012 were collected, and the epidemiological profiles were described. The saliva and brain specimens were collected from dogs in Quanzhou, Longyan and Sanming cities of the province, and the rabies virus antigen was determined in the canine saliva specimens using an ELISA assay. Rabies virus RNA was extracted from canine brain specimens, and rabies virus nucleoprotein gene was amplified using a nested RT-PCR assay, followed by sequencing and genotyping. A total of 226 human rabies cases were reported in Fujian Province from 2002 to 2012, in which 197 cases were detected in three cities of Quanzhou, Longyan and Sanming. ELISA assay revealed positive rabies virus antigen in six of eight rabid dogs and 165 of 3492 seemingly healthy dogs. The full-length gene fragment of the rabies virus nucleoprotein gene was amplified from the brain specimens of seven rabid dogs and 12 seemingly healthy dogs. Sequence alignment and phylogenetic analysis revealed that these 19 rabies virus nucleoprotein genes all belonged to genotype I, and were classified into three genetic groups. Sequencing analysis showed a 99.7% to 100% intra-group and an 86.4% to 89.3% inter-group homology. This study is the first description pertaining to the epidemiological characteristics of human rabies cases and characterization of the rabies virus nucleoprotein gene in dogs in Fujian Province, Southeast China. Our findings may provide valuable knowledge for the development of strategies targeting the prevention and control of

    Palembang as the capital city of South Sumatera Province is one of the metropolitan cities in Indonesia that flooded almost every year. Flood in the city is highly related to Musi River Basin. Based on Indonesia National Agency of Disaster Management (BNPB), the level of flood hazard is high. Many natural factors caused flood in the city such as high intensity of rainfall, inadequate drainage capacity, and also backwater flow due to spring tide. Furthermore, anthropogenic factors such as population increase, land cover/use change, and garbage problem make flood problem become worse. The objective of this study is to develop flood hazard map of Palembang City by using two dimensional model. HEC-RAS 5.0 is used as modelling tool which is verified with field observation data. There are 21 sub catchments of Musi River Basin in the flood simulation. The level of flood hazard refers to Head Regulation of BNPB number 2 in 2012 regarding general guideline of disaster risk assessment. The result for 25 year return per iod of flood shows that with 112.47 km2 area of inundation, 14 sub catchments are categorized in high hazard level. It is expected that the hazard map can be used for risk assessment.

    Full Text Available The idea of a circular economy (CE, which differs from traditional linear economy with a high consumption of natural resources and pollution, has captured much interest and attention. This paper uses a CE system of coal power and cement in Kongtong District, Pingliang City, Gansu Province, China as a case study to analyze the comprehensive effects of CE paradigm. Our simulation results, based on system dynamics (SD modeling, infer that the transformation of manufacturing towards a CE system can prominently help coal power and cement enterprises reduce waste emission and increase economic profits. Through solid waste exchanges, a power plant can achieve over RMB 80 million of additional revenue per year at the highest level. CE also contributes to the reduction of regional pollution, saves mineral resources, and improves the atmospheric environment, an accumulated total of 14.11 million t of natural gypsum and 22.67 million t of coal can be saved. This sets a promising example for coal power and cement plants worldwide. Effective regulatory measures and further optimization towards a circular economy system are essential in maintaining the stable development of a CE system due to the risk of surplus production of upstream industries and other defects.

    Objective By analyzing the under 5 mortality rate (U5MR) and its contributors in Zhejiang Province of China from 2000 to 2009, we tried to understand the trend of U5MR change in Zhejiang Province and thus propose strategies to reduce child mortality. Methods Thirty cities/counties/districts from Zhejiang Province were selected using stratified cluster sampling approach. Children under five years in these areas were enrolled as the subjects. The U5MR and its contributors were analyzed in terms of age, migration status of mothers, and other indicators using classic descriptive methods and Chi square test. Results The U5MR in Zhejiang Province showed a declining trend from 14.83‰ in 2000 to 9.49‰ in 2009. In 2009, the U5MR was significantly higher in the rural areas than in the urban areas (9.14‰ vs.6.50‰, Pbirth/low birth weight was the leading cause of U5MR in 2009. More specifically, preterm birth/low birth weight, congenital heart disease, and birth asphyxia were the top three causes of deaths among infants (falls were the leading causes of deaths among children (1-4 years). Conclusion The U5MR in Zhejiang Province in 2009 differed between urban areas and rural areas and between floating populations and local residents. The main causes of death differ between infants and young children. Prevention of preterm birth/low birth weight and congenital anomalies will reduce infant death, while the main intervention for young children is to avoid accidental injuries. PMID:26835282

    Urbanization process creates a tremendous spatial phenomenon since the last century. Especially for the country of the South, the phenomenon is still relevant to the situation today and the processes will still going until the foreseeable future. The metropolitan-based of urbanization process involves the development of peri-urban areas, which could be defined as transitional zones between city and rural areas characterized by integrated mixed-structures of agricultural and non-agricultural activities. This article reveals the characteristics of periurbanization process of an emerging secondary city in Java, which uses Surakarta, the second largest city in Central Java Province based on the population size, as the case. During the last ten years, there have been significant changes in peri-urban areas regarding urban population, land use, and urban activities that strengthening the contribution of the urban component into peri-urban system.

    A mass of Longquan celadon shards were excavated from the Chuzhou site of Huai'an City in Jiangsu Province, China. These celadon shards were fired during the period of the Late Yuan Dynasty to the Tianshun era of the Ming Dynasty, as identified by archaeologists at Nanjing Museum. In order to research the chemical composition features of this ancient celadon porcelain, energy dispersive X-ray fluorescence (EDXRF) for non-destructive analysis was used to determine the chemical composition of the porcelain body and glaze in these shards. The results indicate that Ti and Fe in the body of Longquan celadon are characteristic elements which can distinguish porcelain produced during the Late Yuan Dynasty from those produced in the Ming Dynasties. The results of the principal component analysis (PCA) show that different body and glaze raw materials were used for the production of porcelain in different periods and the raw materials of the body and glaze are also different for various vessel shapes. The chemical compositions in the porcelain body of civilian ware are slightly different. The imperial and civilian Longquan celadon porcelains produced during the Hongwu era to the Tianshun era of the Ming Dynasty are distinguishable by the MnO, Fe2O3, Rb2O and SrO content in their porcelain glaze.

    Land consolidation, as one of the major driving forces for the changes of land use/cover, has significant impacts on landscape patterns, ecological functions, and ecosystem services. In this paper, a land consolidation project conducted in Da'an City, Jinlin Province, China, was selected to evaluate the ecosystem service values before and after land consolidation at three spatial scales, i. e., village, town, and county. The results indicated that the land consolidation with the goal to increase the area of cultivated land might cause the decrease of the saline and alkaline land, grassland, and wetland. In addition, land consolidation resulted in the reduction of the total ecosystem service values at varying degree at the three scales. Compared to the pre-consolidation status, the total post-consolidation ecosystem service values at the village, town and county scales were 7.96, 843.01 and 1205.86 million yuan, and reduced by 10.5%, 14.2% and 33.1%, respectively. Based on the evaluation of ecosystem service value, strategies of landscape ecological design were discussed to improve the ecological functions and to provide the guidance for the sustainable development of land consolidation.

    Like other big cities in Indonesia, Semarang City as the capital of Central Java Province also has various city problems, one of them is the transportation problem. Transportation problems arise due to increased mobility of society that is not in balanced with the public transportation facilities and infrastructure availability. In order to create a better transportation system, the local government of Semarang City held Trans Semarang bus rapid transit (BRT) which began operating in 2010. This study aims to analyze the feasibility of BRT Trans Semarang corridor VI shelters. This research uses descriptive critique technique. The results are expected to be considered in determining the right policy in creating a better transportation system. Based on observations made, the majority of BRT Trans Semarang corridor VI uses non-permanent shelters and is less feasible to be a BRT shelter. Thus, the local government is expected to improve the feasibility of BRT Trans Semarang shelter so that the sense of security and comfort can be obtained by users of BRT. In addition, the local government is also expected to maintain the quality of services provided. These services include ticket service, the condition of buses, speed and waiting time, as well as the placement and condition of shelters.

  18. An allometric scaling relation based on logistic growth of cities

    Science.gov (United States)

    Chen, Yanguang

    2014-08-01

    The relationships between urban area and population size have been empirically demonstrated to follow the scaling law of allometric growth. This allometric scaling is based on exponential growth of city size and can be termed "exponential allometry", which is associated with the concepts of fractals. However, both city population and urban area comply with the course of logistic growth rather than exponential growth. In this paper, I will present a new allometric scaling based on logistic growth to solve the abovementioned problem. The logistic growth is a process of replacement dynamics. Defining a pair of replacement quotients as new measurements, which are functions of urban area and population, we can derive an allometric scaling relation from the logistic processes of urban growth, which can be termed "logistic allometry". The exponential allometric relation between urban area and population is the approximate expression of the logistic allometric equation when the city size is not large enough. The proper range of the allometric scaling exponent value is reconsidered through the logistic process. Then, a medium-sized city of Henan Province, China, is employed as an example to validate the new allometric relation. The logistic allometry is helpful for further understanding the fractal property and self-organized process of urban evolution in the right perspective.

    The Tertiary sedimentary basins are distributed along the eastern coast of Korean Peninsula. The northernmost Bukpyeong Basin is located in Donghae City, Gangwon-do Province, Korea. The Bukpyeong Basin consists of Bukpyeong Formation and Dogyeongri Conglomerate in ascending order. The geologic age of Bukpyeong Formation has been suggested as from Early Miocene to Pliocene, In particular, Lee & Jacobs (2010) suggested the age of the Bukpyeong Formation as late Early Miocene to early Middle Miocene based on the fossils of rodent teeth. Sedimentary environment has been thought as mainly fresh water lake and/or swamp partly influenced by marine water. Lately, new outcrops of Bukpyeong Formation were exposed during the road construction and abundant fossil plants were yielded from the newly exposed outcrops. As a result of palaeobotanical studies 47 genera of 23 families have been found. This fossil plant assemblage is composed of gymnosperms and dicotyledons. Gymnosperms were Pinaceae (e.g., Pinus, Tsuga), Sciadopityaceae (e.g., Sciadopitys) and Cupressaceae with well-preserved Metasequoia cones. Dicotyledons were deciduous trees such as Betulaceae (e.g., Alnus, Carpinus) and Sapindaceae (e.g., Acer, Aesculus, Sapindus), and evergreen trees such as evergreen Fagaceae (e.g., Castanopsis, Cyclobalanopsis, Pasania) and Lauraceae (e.g., Cinnamomum, Machilus). In addition, fresh water plants such as Hemitrapa (Lytraceae) and Ceratophyllum (Ceratophyllaceae) were also found. The fossil plant assemblage of the Bukpyeong Formation supported the freshwater environment implied by previous studies. It can be suggested that the palaeoflora of Bukpyeong Formation was oak-laurel forest with broad-leaved evergreen and deciduous trees accompanying commonly by conifers of Pinaceae and Cupressaceae under warm-temperate climate.

    The paper presents the development of a comprehensive wind atlas of the Province of Quebec. This study differs from previous studies by 1) use of a standard classification index to categorize the wind resource, 2) extensive review of surface and upper air data available for the Province to define the wind resource, and 3) integration of available wind data with the topography of the Province. The wind resource in the Province of Quebec is classified using the scheme proposed by Battelle-Pacific Northwest Laboratory (PNL). The Battelle-PNL classification is a numerical one which includes rankings from Wind Power Class 1 (lowest) to Wind Power Class 7 (highest). Associated with each numerical classification is a range of wind power and associated mean wind speed at 10 m and 50 m above ground level. For this study, a classification for 30 m above ground level was interpolated and used. A significant amount of wind data was gathered for the Province. These data were obtained from Atmospheric Environment Service (AES), Canada, from wind project developers, and from climatological summaries of surface and upper air data. A total of 35 primary data sites were selected in the Province. Although a number of wind data sites in the Province were identified and used in the analysis, large areas of the Province lacked any specific wind information. The Province was divided into grid blocks having dimensions of 1/4 o latitude by 1/3 o longitude. Each grid block is assigned a numerical Wind Power Class value ranging from 1 to 7. This value is based on the integration of the available wind data and the topography within the square. The majority of the Province was classified as 1 or 2. Coastal locations and topographic features in the interior of the Province typically have Wind Power Class 3 or higher. (author)

    In China historical and cultural heritage resources include historically and culturally famous cities, towns, villages, blocks, immovable cultural relics and the scenic spots with cultural connotation. The spatial distribution laws of these resources are always directly connected to the regional physical geography, historical development and historical traffic geography and have high research values. Meanwhile, the exhibition and use of these resources are greatly influenced by traffic and tourism and other plans at the provincial level, and it is of great realistic significance to offer proposals on traffic and so on that are beneficial to the exhibition of heritage resources based on the research of province distribution laws. This paper takes the spatial analysis of Geographic Information System (GIS) as the basic technological means and all historical and cultural resources in China's Zhejiang Province as research objects, and finds out in the space the accumulation areas and accumulation belts of Zhejiang Province's historic cities and cultural resources through overlay analysis and density analysis, etc. It then discusses the reasons of the formation of these accumulation areas and accumulation belts by combining with the analysis of physical geography and historical geography and so on, and in the end, linking the tourism planning and traffic planning at the provincial level, it provides suggestions on the exhibition and use of accumulation areas and accumulation belts of historic cities and cultural resources.

    Indica-japonica hybridization is one of the most important breeding methods in China, whereas identifying subspecies differentiation mechanisms is the key in indica-japonica hybridization breeding. By using InDels (Insert/Deletion) and ILPs (Intron Length Polymorphism), an analysis was made on the F6 populations derived from the hybridization of indica-japonica (Qishanzhan/Akihikari) planted in Liaoning and Guangdong provinces and generated by bulk harvesting (BM), single-seed descent methods (SSD), and pedigree method (PM). No segregation distortion was observed for the BM and SSD populations. The frequency distribution of japonica kinship percentage (Dj) was concentrated in 40%-60%. The PM populations in the two provinces presented indica-deviated distribution (30%-55%), with significant difference between Guangdong (38%) and Liaoning (42%). In addition, there was a significant positive correlation between the Dj and the kinship of functional gene regions in the BM and SSD populations. However, part of the positive correlation was broken in the PM populations that showed a regular distribution in the genotype patterns of indica and japonica loci. The above results demonstrated that artificial selection could be the main factor affecting the population differentiation in indica-japonica hybridization, and, with the synergistic effect of natural selection, induced the phenomenon of segregation distortion. There existed a close relationship between the differentiation of subspecies and the important agronomic traits, which could be the main reason why indica-japonica hybridiation breeding could not achieve the expected effect of combining the two subspecies advantages.

    Based on Sichuan province environmental statistical survey data and other relevant activity data, volatile organic compounds (VOCs) emissions from typical anthropogenic sources in Sichuan province were calculated for the year of 2011 by applying the emission factor method. Besides, ozone and secondary organic aerosol formation potentials of these typical anthropogenic sources were discussed. The total VOC emission from these sources was about 482 kt in Sichuan province, biomass burning, solvent utilization, industrial processes, storage and distribution of fuel, and fossil fuel combustion contributed 174 kt, 153 kt, 121 kt, 21 kt and 13 kt, respectively; architecture wall painting, furniture coating, wood decoration painting and artificial board were the major emission sectors of the solvent utilization; while for the industrial processes, 19.4% of VOCs emission was from the wine industry. Chengdu was the largest contributor compared to the other cities in Sichuan, whose VOCs emission from these typical anthropogenic sources in 2011 was 112 kt. OFP of these sources was 1,930 kt altogether. Solvent utilization contributed 50.5% of the total SOA formation potentials, biomass burning and industrial processes both contributed about 23% , with storage and distribution of fuel and fossil fuel combustion accounting for 1% and 1.4%, respectively.

    The study aims to investigate the cognition degree and influencing factors of first aid knowledge among dentists in Sichuan province, and to provide suggestions for the training of oral clinician. A questionnaire was designed for this study. It included the basic situation of population, first aid knowledge level, emergency situation often encountered in stomatology clinic, first aid training situation, learning approach and attitude of first aid knowledge, etc. This questionnaire was used to investigate the dentists of medical institutions in various cities in Sichuan province. The survey results was statistical analyzed. There were 245 valid questionnaires. 1) The level of first aid knowledge of dentists was generally lower in Sichuan province. Work department and other departments work experience were the influencing factors of knowledge level of first aid knowledge among dentists. 2) 87.3% of dentists believed that it was very necessary to master the knowledge of first aid, but in the event of an emergency situation, 73.5% of dentists only can find other doctors to guide themselves to help. 3) The most common way to learn first aid knowledge was through work experience and medical school's first aid course. Dentists should strengthen the learning and training to improve the first aid skill.

    Full Text Available A biologically productive area was used in the ecological footprint method to measure the demand and impact of human activities on the natural capital, and further, to judge whether the impact is within the scope of the regional bio-capacity. In this presentation, an indicator “ecological footprint distance (Def” is proposed. The results indicated that the proposed indicator Def could identify the outward extension of a city’s ecological footprint with the city’s rapid expansion. From 2008 to 2012, the proportion of imported bio-capacity increased approximately from 48% to 64%, which implied that the ecological impact of Beijing had expanded year by year. The Def of Beijing increased from 567 km in 2008 to 677 km in 2012, with an average annual increase of about 25 km. From the perspective of seasonal change, Beijing’s ecological footprint distance in winter and spring was much higher than in summer and fall. The main features of provincial-spatial distribution of Beijing’s Def were as follows: grain and oil and meat and eggs were mainly supplied by Heilongjiang, Jilin, Liaoning, Hebei and Inner Mongolia; yet vegetable and fruit were mainly supplied by Hainan, Guangdong, Hebei and Shandong. Measures should be taken to decentralize the sources of imported bio-capacity, so as to ensure a sustainable development in Metropolitan cities.

    Denpasar city is a Capital City of Bali Province and one of the leading tourist destinations in Indonesia. Denpasar area is relatively flat with high rain fall intensity with the domince of settlement. This makes Denpasar City becomes prone area of flood. The aim of this research is to find out the spatial distribution flood hazard and the risk of population which are affected to the flood hazard. Weighting, scoring and overlaying method were used in this research. Six indicators were used to analyze the flood hazard: landuse, rainfall, type of soil, slope, altitute and drainage density. The vulnerability is analyzed per Desa or Kelurahan (Rustic/Neighborhood) with the indicator of age, education and population density. Risk was calculated by multiplied hazard with vulnerability and divided with coping capacity. In this research, coping capacity is determined by the amount of internal budget for each Desa or Kelurahan for development purpose. Flood risk in Denpasar city is divided into five classes, very low risk, low risk, medium risk, high risk and very high risk. Total population with very high risk reached 202478 people or 13.16% of total population. The total area is 780.7 ha or 16.02% from total settlement in Denpasar city. Total population with high risk reached 202478 people or 13.16% of total population. The total area is 780.7 ha or 16.02% from total settlement in Denpasar city. The number of population with medium risk reached 202478 people or 33.51% of total population which occupied 22.95% of total settlements or 1118.18 ha. The total number of population with low risk reached 79435 people or 13.14% of total population with area of low flood risk is 716.89 ha or 14.71% of total settlements in Denpasar City. Very low flood risk with total population at risk reached 19184 people or 31.74% of total population and occupied 2003.54 areas or 41.12% of total areas of settlements.

    In order to obtain unique information of Ganoderma lucidum spores, FTIR microspectroscopy was used to study G. lucidum spores from Anhui Province (A), Liaoning Province (B) and Shangdong Province (C) of China. IR micro-spectra were acquired with high-resolution and well-reproducibility. The IR spectra of G. lucidum spores from different areas were similar and mainly made up of the absorption bands of polysaccharide, sterols, proteins, fatty acids, etc. The results of curve fitting indicated the protein secondary structures were dissimilar among the above G. lucidum spores. To identify G. lucidum spores from different areas, the H1078/H1640 value might be a potentially useful factor, furthermore FTIR microspectroscopy could realize this identification efficiently with the help of hierarchical cluster analysis. The result indicates FTIR microspectroscopy is an efficient tool for identification of G. lucidum spores from different areas. The result also suggests FTIR microspectroscopy is a potentially useful tool for the study of TCM.

    Full Text Available Environmental factors are among the key determinants of real estate prices. They include landscape attractiveness, land relief, exposure to sunlight and proximity to natural features. In large urban centers, traffic noise emissions significantly affect decision-making on the real estate market. Weakly developed road networks and the absence of ring roads that shift road traffic outside residential districts are a widespread problem in the cities of Central-Eastern Europe. The prevention of traffic noise pollution, one of the key environmental problems in Europe, is an important goal of European Union policy. This paper analyzes the correlations between apartment prices and traffic noise levels in Olsztyn, the capital city of the Warminsko-Mazurskie Voivodeship (province in north-eastern Poland. A linear correlation analysis was performed, and the distribution of unit prices of apartments was mapped by ordinary kriging.

    Toxolasma gondii is one of the most important obligate intracellular protozoan parasites. Recently, toxoplasmosis is of increasing concerns because T. gondii not only has a worldwide distribution but also can infect virtually all warm-blooded hosts including donkeys. However, limited information is available concerning the genetic characterization of T. gondii in donkeys in northeastern China. In this study, a total of 302 brain tissue samples collected from donkeys from Jilin (n=108) and Liaoning (n=194) provinces, northeastern China, were examined for T. gondii infection by semi-nested PCR of B1 gene. The positive samples were genotyped at 11 loci (i.e., SAG1, alternative SAG2, 5'-and 3'-SAG2, SAG3, L358, BTUB, c22-8, GRA6, c29-2, PK1 and Apico) using polymerase chain reaction-restriction fragment length polymorphism technology. Of 302 brain tissue samples, 19 (6.29%) were PCR-positive for T. gondii. The prevalence rates of T. gondii were 6.48% (7/108) and 6.19% (12/194) in Jilin Province and Liaoning Province, respectively. The prevalence of T. gondii in different season groups varied from 5.56% to 7.41%. The prevalence of T. gondii in "Cage-free" donkeys was higher than that in "Captive" donkeys. Of the 19 positive samples, only two isolates were successfully genotyped at all loci, three were genotyped at 9 loci. In total, four samples belong to ToxoDB genotype #9, one belong to ToxoDB genotype #10. This is firstly characterized the T. gondii isolates from donkeys in northeastern China. The results of the present study will improve the information of the distribution of T. gondii genotypes in China. Copyright © 2017. Published by Elsevier B.V.

    Full Text Available The development of suburban areas of Malang City has developed an expansion of built-up areas between urban and suburban areas. There has been a great phenomenon that mostly occurs along the suburban areas where industrial activities took place. This study aims to determine what factors have influenced the land use change in the suburban areas of Malang City by employing “GeoDa” application. It is one of the Geographical Information System applications that particularly deals with statistical analysis. To achieve this purpose, the objectives are: delineating the study area, analyzing the characteristics of land use change, assessing and analyzing the variable influencing the land use change. The results have shown that the characteristics of land use change, such as population, distance, migration, and occupation transformation are directly proportional to the land use change. It has also been identified that the high level of density is only located in the surrounding areas of industries. From the assessed variables through the statistical model, population (X1, density (X2 and migration (X3 are found as the influencing factors of land use change.

    Full Text Available Waste-to-energy (WTE is a viable option for municipal solid waste (MSW management and a renewable energy source. MSW is a chronic problem in Saudi Arabia and more specifically in Saudi Urban areas. The MSW practices in KSA are simply done by collecting the waste and dumping it in open landfill sites. KSA is considering WTE as a potential renewable energy source that can contribute to electricity demand in the Kingdom. This research aims to assess potential contribution of WTE facility to meet electricity demand in the three main cities in the Western Province of Saudi Arabia and to provide an alternative solution to landfills. Three scenarios for WTE utilization were developed: Mass Burn, Mass Burn with recycling, and refused derived fuel (RDF with biomethanation. The Mass Burn scenario implies full waste stream incineration; the Mass Burn with recycling scenario considers segregation of reusable materials and the waste leftover for incineration; while RDF with biomethanation considers segregation of general waste stream into inorganic and organic waste and utilizes organic waste for biomethanation and inorganic for RDF. The analyses were completed for Jeddah, Makkah, and Madina cities; with current total population of about 6.3 million. The results show that Jeddah has the potential to produce about 180 MW of electricity based on incineration scenario; about 11.25 MW based on incineration with recycling scenario; and about 87.3 MW based RDF with biomethanation scenario by the year 2032. These values and other two cities values are based on theoretical ideals and they help in identifying the optimal WTE techniques for each city.

    Full Text Available This article aims to explain from a theoretical conceptual approach the particularities that exist in Victoria, San Fernando, Buenos Aires, from its urban production. Through a series of field works, semi-structured interviews and observations, it was possible to perceive that in this locality, there are three logics of city production, market, state and necessity, according to Abramo, P. (2002. The post-development cities of Latin America, a space in which constant tensions are generated that alter the harmonious development of daily life and the interaction of those who inhabit the area. On the other hand, it is also perceived that the inhabitants naturalize that way of life, their spatial disposition, the progressive privatization of public areas and the proliferation of closed housing estates. Here is a quote that we have heard repeatedly in interviews with the neighbors: "No one in Victoria gives a ball to anyone." At the moment of understanding Victoria from the theory, we take into account such concepts as the "heterotopy" of Foucault M. (1967 - understood as the juxtaposition of spaces that would be incompatible -the term "com-fusa city" (Abramo P. - as an urban structure that interweaves two traditional models (the Mediterranean compact and the Anglo-Saxon diffused, the notion of "privatopia" by I.Rodriguez Chumillas (2005 and E. Mckenzie (1994 as private spatial consolidation, and finally the concepts: informative and dual cities of R Castells (1995 terms that emerge from the process of globalization, which may be useful to think about the reality of Victoria .

    While the demand for health services keep escalating at the grass roots or rural areas of China, a substantial portion of healthcare resources remain stagnant in the more developed cities and this has entrenched health inequity in many parts of China. At its conception, China's Deepen Medical Reform started in 2012 was intended to flush out possible disparities and promote a more equitable and efficient distribution of healthcare resources. Nearly half a decade of this reform, there are uncertainties as to whether the attainment of the objectives of the reform is in sight. Using a hybrid of panel data analysis and an augmented data envelopment analysis (DEA), we model human resources, material, finance to determine their technical and scale efficiency to comprehensively evaluate the transverse and longitudinal allocation efficiency of community health resources in Jiangsu Province. We observed that the Deepen Medical Reform in China has led to an increase concern to ensure efficient allocation of community health resources by health policy makers in the province. This has led to greater efficiency in health resource allocation in Jiangsu in general but serious regional or municipal disparities still exist. Using the DEA model, we note that the output from the Community Health Centers does not commensurate with the substantial resources (human resources, materials, and financial) invested in them. We further observe that the case is worst in less-developed Northern parts of Jiangsu Province. The government of Jiangsu Province could improve the efficiency of health resource allocation by improving the community health service system, rationalizing the allocation of health personnel, optimizing the allocation of material resources, and enhancing the level of health of financial resource allocation.

    Full Text Available Antibiotic resistance has become a global public health concern as a wide num­ber of resistant bacteria are continuously emerging. Animals have been pointed out as one of the sources of antibiotic-resistant bacteria that can be transferred to humans. To enrich the data on antibiotic resistance in animals in Rwanda, a cross-sectional study was carried out in the Eastern Province and in Kigali City to isolate Escherichia coli from free-range and commercial poultry farms. Fecal samples were collected from 294 poultry farms and E. coli strains were isolated and identified. In total 241 E. coli isolates were subjected to an antibi­otic sensitivity test using five antibiotics (gentamicin, streptomycin, rifampicin, doxycycline and erythromycin. Antibiotic use in poultry was low in free-range poultry farms (30.9% compared to layer and broiler production farms (100%. Among 151 farmers who reported using antibiotics in poultry, almost half (49.7% always used antibiotics with a veterinarian prescription. Out of 241 E. coli isolates, 43.2% had a multiple resistance to four of the five antibiotics tested. Almost all the isolates (98.8% were resistant to erythromycin, 78.8% were resistant to streptomycin, 77.6% were resistant to doxycycline, 69.3% were resistant to rifampicin and only a few were resistant to gentamicin (3.7%. No statistically significant difference was observed regarding isolate resistance against antibiotics according to the farming system type. However, resistance of isolates to doxycycline was significantly higher in farms where antibiotic use was reported (84% than in farms where antibiotic use was not reported (70%. The observed antibiotic resistance of E. coli shows the existence of a potential source of resistance that can be transferred to pathogenic bacteria and impact humans as well as animals.

    To isolate and identify Nocardia spp. from soil in different regions of Isfahan province in the center of Iran. This study was conducted in 32 districts (16 cities and 16 villages) in Isfahan province during two years. A total of 800 soil samples from these regions were studied by using kanamycin. The isolated Nocardia species were examined by gram and acid-fast staining and were identified biochemically and morphologically. The frequency and distribution of Nocardia spp. were determined in relation to different factors such as soil pH and temperate climate. From 153 (19.1%) Nocardia isolates identified, Nocardia asteroids (N. asteroids) complex (45.5%) and Nocardia brasiliensis (N. brasiliensis) (24.7%) were the most frequently isolated species, followed by Nocardia otitidiscaviarum (2.2%), Nocardiopsis dassonvillei, Actinomadura actinomadura (each 1.7%) and Nocardia transvalensis (1.1%) and also unknown spp. (23.0%). In this study, most species (54.4%) of Nocardia, especially N. asteroides complex were isolated from soils with pH: 7.01-8, whereas in pH: 8.01-9 more N. brasiliensis was isolated. The most Nocardia spp. was detected from regions with semi-nomadic and temperate climate (41.1%). N. asteroids complex is more prevalent in Isfahan province and soil can be a potential source of nocardiosis infections. It is to be considering that climate and soil pH are involved in the frequency and diversity of aerobic Actinomycetes.

    On April 23, 2016, the Democratic Republic of the Congo's (DRC's) Ministry of Health declared a yellow fever outbreak. As of May 24, 2016, approximately 90% of suspected yellow fever cases (n = 459) and deaths (45) were reported in a single province, Kongo Central Province, that borders Angola, where a large yellow fever outbreak had begun in December 2015. Two yellow fever mass vaccination campaigns were conducted in Kongo Central Province during May 25-June 7, 2016 and August 17-28, 2016. In June 2016, the DRC Ministry of Health requested assistance from CDC to control the outbreak. As of August 18, 2016, a total of 410 suspected yellow fever cases and 42 deaths were reported in Kongo Central Province. Thirty seven of the 393 specimens tested in the laboratory were confirmed as positive for yellow fever virus (local outbreak threshold is one laboratory-confirmed case of yellow fever). Although not well-documented for this outbreak, malaria, viral hepatitis, and typhoid fever are common differential diagnoses among suspected yellow fever cases in this region. Other possible diagnoses include Zika, West Nile, or dengue viruses; however, no laboratory-confirmed cases of these viruses were reported. Thirty five of the 37 cases of yellow fever were imported from Angola. Two-thirds of confirmed cases occurred in persons who crossed the DRC-Angola border at one market city on the DRC side, where ≤40,000 travelers cross the border each week on market day. Strategies to improve coordination between health surveillance and cross-border trade activities at land borders and to enhance laboratory and case-based surveillance and health border screening capacity are needed to prevent and control future yellow fever outbreaks.

  19. Did the Establishment of Poyang Lake Eco-Economic Zone Increase Agricultural Labor Productivity in Jiangxi Province, China?

    Full Text Available In this paper, we take the establishment of Poyang Lake Eco-Economic Zone in 2009 as a quasi-natural experiment, to evaluate its influence on the agricultural labor productivity in Jiangxi Province, China. The estimation results of the DID method show that the establishment of the zone reduced agricultural labor productivity by 3.1%, lowering farmers’ net income by 2.5% and reducing the agricultural GDP by 3.6%. Furthermore, this negative effect has increased year after year since 2009. However, the heterogeneity analysis implies that the agricultural labor productivities of all cities in Jiangxi Province will ultimately converge. We find that the lack of agricultural R&D activities and the abuse of chemical fertilizers may be the main reasons behind the negative influence of the policy, by examining two possible transmission channels—the R&D investment and technological substitution. Corresponding policy implications are also provided.

    Full Text Available Authors examine the question of the types, scale, efficiency of public aid and social support of soldiers' families in Yenisei province during the First World War. Particular attention is paid to the activities of cities and urban guardianship organizations that have paid to families of the mobilized amount exceeding the amount of state benefits. It is shown that in the rural guardianship organizations did not have more money. They failed to organize labor help with the agricultural work. Soldiers' families reduced tillage, many of them wanted to move to the provincial center. Siberian city were not a major commercial and industrial centers, their budgets have been modest. Siberia had no zemstvo institutions, therefore, the city suffered heavy costs for the solution of many other problems caused by wartime (the organization of assistance to refugees and the injured, the fight against the high cost and lack of, the development of cooperatives, and others, they were making regular payments for all-Russian charitable societies. The flow of donations to urban guardianship and charitable organizations has decreased dramatically in 1916, and the number in need has increased significantly, the municipal government began to curtail payments to soldiers' families. The discontent of the soldiers' wives resulted in the pogroms of malls and attacks against members of municipal self-government bodies of Minusinsk, Krasnoyarsk, Kansk in 1916–1917.

    Full Text Available The main objective of this article is to discuss and present data showing the everyday practices of a city: Manáos in the second half of the nineteenth century, which had become a place of multiple sociability, where a mix of people from overseas decided it as a place for residence, or income generation. In this perspective, the vision of the "outside" is distant and the local elite, as to the latter, the city boasted the "pride of civilization" and its inhabitants all had left behind the customs and habits of Manáos of old, connected to the delay, the uncivil, the river and the indigenous. We leave especially the iconographic analysis in this souvenir album of the Chicago Exposition of 1883, which Manaus was presented as a place of wealth and civilization and the environment of the province, a place of rurality and extensive nature. Thus, we will highlight the everyday life of this city, this routine marked by different "ways of doing."

    differences. Under the BAU scenario, the construction land is mainly in the south of Lijiang City and the northeastern part of Kunming. Under the FP scenario, the new construction land is concentrated near the Lashi dam in northern Yunnan Province, and the high-quality arable land in the valley will be better protected. The research results can provide reference for the optimization of land use pattern in Yunnan Province, and provide scientific basis for land use management and planning. Based on the value of ecosystem services, we should implement the policy of strict protection of arable land, both to ensure food supply and promote the healthy development of ecological environment.

    Many contributions have been made in the studies of the factors that influence public acceptance of nuclear power. However, previous studies seldom focused on nuclear power plants in the planning stage. Actually public perception is usually more sensitive at the preliminary planning stage of a nuclear power station. Mainly utilizing questionnaire survey and focus group methods, we have identified the factors that are correlated with local acceptance of planned nuclear power plants in China. We conducted our survey in two cities, Huludao, Liaoning province in northern China, and Shanwei, Guangdong province in southern China, where the local government was planning to build its first nuclear power plant. We find that people who live closer to the plant sites are less willing to accept nuclear power than those who live farther away. As for “surface psychology” factors, perceived benefits and risks significantly influence local acceptance. As for “deep psychology” factors, emotional identification and social trust can significantly influence local acceptance, while perceived knowledge cannot. When citizens are unfamiliar with nuclear power plants, they are more inclined to evaluate the benefits and risks through emotional identification and social trust, rather than through pure rational deduction based on concrete facts. - Highlights: • We focus on the local acceptance of nuclear power in the planning stages. • People who live closer to plant sites are less willing to accept nuclear power. • Perceived benefits and risks significantly influence local acceptance. • Emotional identification and trust can significantly influence local acceptance. • While perceived knowledge cannot significantly influence local acceptance.

    Full Text Available Rodents are mammals that comprise more than 2000 species and approximately 30 families. There are many morphological and ecological differences among them as variations in their shape, size, weight and habitat. In addition to significant economic losses, rodents have a major role in the dissemination of infectious diseases caused by viruses, bacteria, parasites or other micro-organisms. Rodents are important reservoirs of diseases which have been observed in many cities of Iran provinces especially along Caspian Sea border to Alborz Mountain. The aim of this study is to assess the geographical distribution of rodents in three provinces of northern part of Iran as reservoir of potential endemic infectious diseases. Rodents in 10 major parts of each of the three provinces of Mazandaran, Gilan and Golestan, northern Iran were collected and a total of 404 rodents were trapped alive. They were determined by the key characteristics such as gender, genus, species, different locations and topological situation. Statistical analysis was performed to characterize the study sample and to correlate all variables and parameters. The distribution frequencies of three, five and six genera of rodents were identified in Mazandaran, Gilan and Golestan provinces respectively. The overall distribution frequency of eight genera of rodents in the three provinces were identified as Rattus (R. norvegicus (67.3%, R. rattus (13.6%, Apodemus sylvaticus (13.9%, Arvicola (1%, Mus musculus (0.3%, Nesokia indica (2.5%, Cricetulus migrates (0.7% and Rhombomys opimus (0.7%. The results of this study determined the geographic distribution of the rodents in the three northern provinces of Iran. It is indicated the association of various distribution and diversity of rodents with provincial location. The overall distribution frequency of eight genera of rodents was recognized in the above three provinces geographical locations. This study confirms epidemiological distribution of

    Full Text Available Today, tourism as a global and social phenomenon has special implication of its own. The mechanism behind the phenomenon intertwines and takes different forms in different times and places and completely different effects on the human beings (de freitas, 2003:47. There are many types of tourism. One of the most important tourism forms is religious tourism. Religious tourism is a combination of travel and religion. Most writers are taking into account religious tourism as a part of cultural tourism. Of course, both are quite different, but these two are tied together, and religion is a part of culture. Religious Cultural Festival is an event that causes tourism to travel to a foreign country for looking for religion and heritage experience. Hence the Muharram ceremonies (Ashura and Tasua as a religious event can be raised as an event that can familiarize domestic and foreign tourists with part of Iranian religious and culture society. Iran is an old and historical country and its present religious is Islam, most of the people are Shia? The ceremonies of Tasua and Ashura in most part of this country with different showings are done. One of those is in Taft city located in Yazd province. This research is with aims to optimize utilization of the Ashura and Tasua religious festival in order to develop Taft city and to remove barriers on the way of Taft religious tourism using the SWOT model. This evaluation model (that evaluated strengths, weaknesses, opportunities and threats is considered one of the best strategies for tourism planning. Methods of data collection and analysis of required data is more documentaries, analytical and Survey research. The results indicate that proximity to population centers and urban centers, such as the city of Yazd and distinctive funeral's style from other parts of Province, are the best strengths for this city's religious tourism. Short duration of tourists stay in the cities and Lack of tourists' economic outputs

    Leishmania infantum is the principal agent of visceral leishmaniosis (kala-azar) in all areas of Iran. The disease is endemic in Fars, Ardabil, East Azerbaijan and Bushehr provinces while it is sporadic in other parts of the country. Dog as a member of canidae family is the main animal reservoir host of kala-azar. The present study was carried out to determine the sero-prevalence of canine leishmaniosis in Mashhad, the capital city of Khorasan Razavi Province, in the north east of Iran. Two-hundred and nine dogs in two different classes including stray and sheepdogs were selected for this cross-sectional study. The blood samples were collected and tested by indirect immunofluorescent antibody test for detection of anti-Leishmania infantum antibodies. The results showed that 16/209 (7.6 %) of blood samples were positive. The sero-prevalence rates in stray and sheepdogs were 11/94 (11.7 %) and 5/115 (4.3 %), respectively (p < 0.05). Based on the results obtained, it is concluded that visceral leishmaniosis is distributed among dogs of this area, also sero-prevalence of canine leishmaniosis in stray dogs higher than sheepdogs.

    Full Text Available Urbanization is a major driver of land use change and global environmental decline. With accelerated urbanization worldwide, it is essential to put in place new policies to conserve urban ecosystems, species and the services these provide in order to secure more sustainable, resilient and livable cities for the 21st century. In urban planning, the concept of resilience has broadly replaced the word sustainability. In recent years, resilience indicators have been gradually developed, but few address urban resilience from a social-ecological systems perspective. We develop a methodological framework to measure urban resilience, define an urban resilience index and apply it to Spanish province capitals as a case study. Results show that most Spanish province capitals are far from being resilient. We conclude that increased efforts to measure urban resilience should be in place, and we offer the urban resilience index as a theoretical framework for measuring resilience in urban social-ecological systems that can be gradually improved as more data become available.

    Vehicle emissions have become a major source of air pollution in Shandong province, which has experienced a sharp growth of vehicle numbers in recent years and now has the largest vehicle population in China. This paper combines the COPERT IV model with the vehicle age distribution to estimate the temporal trends and map the spatial distributions of vehicle emissions in Shandong province during the period ranging from 2000 to 2014. Both conventional air pollutants and greenhouse gases are included. In addition, a high-resolution vehicle emission inventory at the prefecture level is developed and mapped on a 0.05° × 0.05° grid based on road information. Our results show that the emissions of all of the conventional air pollutants have decreased to various extents over the recent past, but greenhouse gas emissions have continued to increase due to the lack of effective control strategies. The total emissions of CO, NMVOC, NOX, PM10, CO2, CH4 and N2O from the Shandong vehicle fleet changed from 1734.5 Gg, 277.9 Gg, 177.0 Gg, 12.4 Gg, 19239.7 Gg, 11.3 Gg and 0.6 Gg, respectively, in 2000 to 1723.3 Gg, 234.2 Gg, 513.8 Gg, 29.5 Gg, 138,419.5 Gg, 15.3 Gg and 3.9 Gg, respectively, in 2014. Vehicle emissions were mainly concentrated in cities and became more dispersed in Shandong province between 2000 and 2014.

    Based on the analysis of geological characteristics and genesis of Niangnianggong deposit, this paper suggested that the deposit is controlled by the EW direction faults and belongs to quartz vein type. Average value of δ 34 S of the ore is 2.19‰, and the variation ranges from 1.6‰ to 4.9‰, which shows the feature of hydrothermal sulfur. The result of lead isotope is fall into original lead zone, which shows the feature of primeval lead system. The result of H-O isotope is close to meteoric line, which means the participation of precipitations. Rb-Sr age of ore is 186.6 Ma, which is similar to the age of diorite dike. Multi-disciplinary analysis concludes that the deposit is a quartz vein type deposit with composite hydrothermal origin. (author)

    Full Text Available Considering the importance of connecting urbanization phenomena and vulnerability assessments, this paper aims to explore vulnerability assessment in three different city sizes in the northern coast of Central Java province of Indonesia. It compares the vulnerability levels of the three cities based on their sizes (that is, levels of urbanization. It uses the most current secondary data from the lowest administrative levels, called as kelurahan (urban village, for its assessment. There are two indexes used to indicate their vulnerability levels, namely exposure and sensitivity index (ESI and adaptive capacity index (ACI. By combining the ESI and ACI, the study found that the kelurahans in Tegal (the medium sized city have similar vulnerability levels. The kelurahans in Semarang (as the big city have more combination of vulnerability levels—indicating that the city has various sensitivity, exposure, as well as adaptive capacity among its kelurahans. In Lasem (the small sized city, due to limitations imposed by adaptation—mostly because of lack of public services and high dependency on primary economic sectors—all of its kelurahans were found to be vulnerable. The study therefore concluded that the bigger a city is, the more the different areas of that city will have varying levels of vulnerability, leading to a high propensity of vulnerability among its inhabitants. On the other hand, the smaller a city is, the less capacity it will have in reducing its emerging vulnerability challenges.

    In recent years, in the Northeast of China, the heating period comes with large range of haze weather. All the units of coal power plants in Jilin Province have completed the cogeneration reformation; they provide local city heat energy. Many people believe that coal power plants heating caused the heavy haze. In is paper, by compared concentration of PM2.5 in environment in heating period and non heating period, meanwhile the capacity of local coal power plants, conclude that the PM2.5 emission of coal power plants not directly cause the heavy haze in Changchun and Jilin in the end of October and early November. In addition, the water-soluble iron composition of PM2.5 coal power plant emissions is compared with environment, which further proves that the heating supply in coal power plants is not the cause of high concentration of PM2.5 in Jilin province.

    Penicillium sp. P6, isolated from coal mine soil at the Qiantong colliery Liaoning Province, Northeast China, can degrade Chinese lignite in 36 h on a plate colony and in 48 h using a 4-day cultured cell-free filtrate. Results of elemental analysis and IR spectrometry indicated that solubilized products exhibited some alterations in comparison to the original lignite. The amount of fulvic acid extracted from the biodegraded lignite was high, and the molecular distribution of the humic acids from biodegraded lignite changed distinctively in comparison to which extracted from the control lignite, possibly due to the depolymerization associated with fungal biodegradation.

    Full Text Available Issues of authenticity and identity are particularly significant in cities where social and cultural change is shaping active transformation of its urban fabric and structure in the post-war condition. In search of sustainable future, Iraqi cities are stretched between the two ends of the spectrum, authentic quarters with its traditional fabric and modern districts with their global sense of living. This paper interrogates the reciprocal influences and distinct qualities and sustainable performance of both authentic and modern quarters of Erbil, the capital of the Iraqi province of Kurdistan, as factors in shaping sustainable urban forms for Iraqi cities. In doing so, the paper, firstly, seeks to highlight the urban identity as an effective factor in relation to sustainable urban form. Secondly, the city of Erbil in Iraq has been chosen as a field study, due to its regional, social, political and historical role in the region. Thirdly, the study emphasises the dynamic activities and performance of residential projects according to rational sustainable criteria. The research concludes that urban identity and the sense of place in traditional and historical places should inform design strategies in order to achieve a more sustainable urban context.

    Green open space is one of the land that its existence is quite important in urban areas where the minimum area is set to reach 30% of the total area of the city. Malang which has an area of 110,6 square kilometers, is one of the major cities in East Java Province that is prone to over-land conversion due to development needs. In support of the green space program, calculation of green space is needed precisely so that remote sensing which has high accuracy is now used for measurement of green space. This study aims to analyze the area of green open space in Malang by using Landsat 8 image in 2015. The method used was the vegetation index that is Normalized Difference Vegetation Index (NDVI). From the study obtained the calculation of green open space was better to use the vegetation index method to avoid the occurrence of misclassification of other types of land use. The results of the calculation of green open space using NDVI found that the area of green open space in Malang City in 2015 reached 39% of the total area.

    Full Text Available The urban heat island effect is often associated with large metropolises. However, in the Netherlands even small cities will be affected by the phenomenon in the future (Hove et al., 2011, due to the dispersed or mosaic urbanisation patterns in particularly the southern part of the country: the province of North Brabant. This study analyses the average night time land surface temperature (LST of 21 North-Brabant urban areas through 22 satellite images retrieved by Modis 11A1 during the 2006 heat wave and uses Landsat 5 Thematic Mapper to map albedo and normalized difference temperature index (NDVI values. Albedo, NDVI and imperviousness are found to play the most relevant role in the increase of night-time LST. The surface cover cluster analysis of these three parameters reveals that the 12 “urban living environment” categories used in the region of North Brabant can actually be reduced to 7 categories, which simplifies the design guidelines to improve the surface thermal behaviour of the different neighbourhoods thus reducing the Urban Heat Island (UHI effect in existing medium size cities and future developments adjacent to those cities.

    Full Text Available The llanera music and culture is a social construction that has been developed for over 200 years in the Colombian-Venezuelan plains. However, this imaginary has been adopted and strengthened in a relatively short time in the Colombian  province of Meta since 1960. The vastness of the Colombian-Venezuelan plains has lead to a differentiation of various types of llanero, as each one of them live and experience the llanera culture in a particular way, depending on the characteristics of the place where they live, their daily tasks, and so on. The ";urban llanero of foothill "; -inhabitant of cities like Yopal and Villavicencio- is multicultural and cosmopolitan; he feels, worships  and experiences the llanera culture and its music, as well as other different kinds of music and visions of the world, in his own particular way. Hence the necessity to think it all again, in order to find a new meaning for the notion of the llanero in the city, adapting it to the urban context and disregarding any static vision of this kind of culture, in order to encourage its construction in the city as an ";urban music";.

    Objective: To evaluate prevalence of hepatitis A antibody (anti-HAV IgG) among population covered by different hepatitis A vaccine immunization strategies in Shandong Province in 2015. Methods: In October 2015, according to the geographical location of Shandong Province, the stratified random sampling method was used to stratify the 17 municipal distrcts, and the random number table method was used for sampling, First, two eastern cites (Qingdao, Rizhao), two western cities (Liaocheng, Zaozhuang) and three central cities (Jinan, Zibo and Laiwu) were selected; secondly, one county was drawn from each city. Finally, the participants were divided into five age groups including ≤7 years (age group covered by free hepatitis A vaccination strategy), 8-11 years (age group who receive hepatitis A vaccination at their own charge), 12-24 years (age group covered by catch-up vaccination of hepatitis A), 25-34 years (age group born before hepatitis A vaccine was used) and ≥35 years (age group born before hepatitis A vaccine was used). After all the paticipants or their guardians asked and registered basic information such as age, gender, home address, blood samples were collected from them and anti-HAV IgG was detected by ELISA method. The positive rate of anti-HAV IgG and 95% CI were calculated. Results: A total of 1 654 participants were involved in the final analysis, including 856 males (51.75%) and 798 females (48.25%) whose mean age was (13.44±13.06) years. The crude positive rate of anti-HAV IgG was 91.41% (1 512/1 654, 95% CI: 89.96%-92.72%) and the age-adjusted rate was 90.93% (95% CI: 90.92%-90.94%). The positive rates of anti-HAV IgG was at the highest level in the age group of ≤7 years (95.90%, 95% CI: 95.88%-95.91%) and was at the lowest level in the age group of 25-34 years (83.23%, 95% CI: 83.21%-83.25%). The age-specific positive rates of anti-HAV IgG in eastern areas (96.79%, 95% CI: 96.78%-96.80%) were higher than those in both middle areas (86.66%, 95

    The Lagoa Real Uranium Province, situated in South Central Bahia in the region of Caetite and Lagoa Real, is considered the most important monomineralic province of Brazil. The urban population who lives in the proximities of this uranium province in the cities of Caetite, Lagoa Real and Livramento uses public supply water, while the inhabitants of the rural area due to long terms of dry weather use water from wells, cisterns, small dams, reservoirs and dikes which are supplied with the rains. In this work it was determined the concentration of uranium in the water consumed by the rural and urban population living in the proximities of the Lagoa Real Uranium Province. The study comprehends 32 sampling spots spread throughout the region of interest. Samples were collected in January and July 2010, covering superficial, underground and public supply water from the region. The uranium concentrations were determined by an inductively coupled plasma mass spectrometer (ICP-MS). Preliminary results showed that the uranium concentrations in the water from the Lagoa Real Uranium Province varied from 0.064 {+-} 0.005 {mu}g.L{sup -1} to 90 {+-} 1,5 {+-}g.L{sup -1}. It was observed that only two of them obtained values higher than the World Health Organization's recommended limit (2011) of 30 {mu}g.L{sup -1} for maximum uranium concentration in the water for human consumption. For a conclusive evaluation, the uranium concentrations results will be analyzed together with total alpha and beta concentrations determined elsewhere for the same samples. (author)

    The Lagoa Real Uranium Province, situated in South Central Bahia in the region of Caetite and Lagoa Real, is considered the most important monomineralic province of Brazil. The urban population who lives in the proximities of this uranium province in the cities of Caetite, Lagoa Real and Livramento uses public supply water, while the inhabitants of the rural area due to long terms of dry weather use water from wells, cisterns, small dams, reservoirs and dikes which are supplied with the rains. In this work it was determined the concentration of uranium in the water consumed by the rural and urban population living in the proximities of the Lagoa Real Uranium Province. The study comprehends 32 sampling spots spread throughout the region of interest. Samples were collected in January and July 2010, covering superficial, underground and public supply water from the region. The uranium concentrations were determined by an inductively coupled plasma mass spectrometer (ICP-MS). Preliminary results showed that the uranium concentrations in the water from the Lagoa Real Uranium Province varied from 0.064 ± 0.005 μg.L -1 to 90 ± 1,5 ±g.L -1 . It was observed that only two of them obtained values higher than the World Health Organization's recommended limit (2011) of 30 μg.L -1 for maximum uranium concentration in the water for human consumption. For a conclusive evaluation, the uranium concentrations results will be analyzed together with total alpha and beta concentrations determined elsewhere for the same samples. (author)

    The underdeveloped institutional framework and trade barriers between China’s provinces make cross-province acquisitions challenging. We explore how Chinese firms can mitigate this problem. Drawing on social network theory we propose that cross-province rotation of political leaders—a key element...... of the promotion system of political cadres in China—is a mechanism enabling growth through cross-province acquisitions. We conceptualize rotated leaders as brokers between two geographically dispersed networks. We contribute to the literature on the characteristics of Chinese social networks, the effect...... of political connections on firm strategy, and the impact of political rotations on firm growth in China’s provinces....

    Full Text Available Trichomonas vaginalis is a causative agent of vaginitis in female and urethritis in men. It is primarily transmitted by sexually route. It is known that each geographical area has its own set of Trichomonas vaginalis strain. Parasite strains in each region have its specific characterizations and different strains of the parasite are able to cause various diseases with the acuity and severity. The aim of this study was to determine the genotyping of Trichomonas vaginalis strains in the Shahrekord city (Chaharmahal Va Bakhtiari province, southwest Iran. A total of 1725 vaginal samples were taken from clinically suspected women for Trichomonas vaginalis infection and 21 specimens were diagnosed as positive by direct smear wet mount and culture repeated passage of the parasite in the modified TYI-S-33 medium. The genomic DNA was extracted from each sample and the nested polymerase chain reaction was applied using specific oligonucleotide primers for actin gene amplification. Finally, the restriction fragment length polymorphism using RsaI, MseI, and HindII restriction enzymes were done on PCR products for genotyping. PCR-RFLP analysis of 21 positive cases (1.22% was showing the most frequent genotype was H (8 cases, followed by G (4 cases, E (3 cases, and P (2 cases. N and I genotypes were detected in each 1 case. Also, there was 2 cases mix (E and H genotype. The findings of the present work were showed 7 different genetic strains in isolated Trichomonas vaginalis from symptomatic and asymptomatic women in Shahrekord city. In this study high level of H genotype in referred women in Shahrekord city was observed and H, G, E, and I genotypes were may be related to burning and itching as well as H, P, and mix genotypes were associated with malodorous discharge with pelvic pain in this region of Iran. For a suggestion, it would be better in further studies the accurate determination of genetic diversity of this parasite done in Chaharmahal Va Bakhtiari

    Although the extraction of mineral wealth has been the major influence in the history of Johannesburg and the surrounding Witwatersrand regions (with about 45% of all gold ever mined coming from there), the discovery of now-famous hominid fossils at the Sterkfontein Caves, and the convening of the world's largest-ever conference on environment and development, are setting a new stage for the future. The United Nations began the second Development and Environment Conference in Johannesburg on August 26, 2002. This meeting addresses the implementation of international goals to fight poverty and protect the global environment that were established at the first such conference held in Rio de Janeiro in 1992. The Johannesburg summit involves about forty thousand participants, and perhaps 100 world leaders. One of several official opening ceremonies for the conference was held at the Sterkfontein Caves to recognize the outstanding universal value of the paleo-anthropological fossils found there.These views from the Multi-angle Imaging SpectroRadiometer (MISR) highlight a number of the land use, vegetation, and geological features found within Gauteng Province (including the urban center of Johannesburg and the capital city Pretoria) and parts of the North West and Free State Provinces. The image on the right displays vegetation in red hues and is a false-color view utilizing data from MISR's near-infrared, red and blue bands. Both the natural-color view (left) and the false-color version were acquired by MISR's nadir camera on June 16, 2002. The urban areas appear as gray-colored pixels in the natural-color view, and exhibit colors corresponding with the relative abundance of vegetation found in the urban parts of this arid region.The mountains trending east-west near the center of the images extend from Pretoria in the east to Rustenberg in the west. These ranges, the Magaliesberg and Witwatersberg, separate the low-lying, hotter bushveld to the north from the cooler

    Full Text Available AIM: To determine the group distribution characteristics of lachrymal duct obstruction diseases in major Li Miao minority areas of Hainan province. METHODS: Totally 5 353 residents were selected and researched by randomized cluster sampling in the major Li Miao minority areas of Hainan province. Ocular examination and lachrymal duct flushing were carried out, and questionnaire survey on lachrymal duct obstruction was conducted. The ratio of lachrymal duct obstruction diseases and group distribution characteristics were analyzed based on above research. RESULTS: The prevalence ratios of lachrymal duct obstruction was 4.47% in major Li Miao minority areas of Hainan province, with 2.62% in urban area, and 5.93% in rural area respectively. Prevalence ratios of men and women group were 1.69% and 6.39% correspondingly. Difference between the two groups was statistically significant(χ2=67.2821, P=0.0000. The highest prevalence ratio was 40-69 year-old group, second one was 70-79 year-old group, especially for women in these groups. The prevalence ratios of Ledong, Lingshui, Baisha and Changjiang county were higher than those of Baoting, Qiongzhong county and Wuzhishan city. No significant difference was found between both eyes. CONCLUSION: In major Li Miao minority areas of Hainan province, lachrymal duct obstruction mainly occurs in 40-79 year-old patients, with specially higher ratio of women. Statistically, significant difference of the prevalence ratio between urban and rural areas exists. The higher prevalence ratio is attributed to age, gender, geographical location, climate condition, health environment and so on. The prevalence ratio is higher in the dry and windy areas than in the humid and less windy areas.

    2010-01-01

    A seismotectonic province is a kind of seismic source where, in general, seismic characteristics are assumed to be uniform. It is different from earthquake-generating geological structures such as faults or folds. It is an area or a zone where earthquakes diffusely occur but no specific geological structure is identified to be responsible for those earthquakes. The terminology, a seismotectonic province is originated from a tectonic province of U.S. federal code, with emphasis on earthquakes. The seismotectonic province is called the seismogenic source in the regulatory guides of U.S. Nuclear Regulatory Commission (NRC), and the zone of diffuse seismicity in a guide of International Atomic Energy Agency (IAEA). In Korea, existing seismotectonic province maps were constructed based on the geological information due to insufficient earthquake data. As understood in its name, however, a seismotectonic province map should be based on the seismic information. Moreover, it should be noted that the Korean (geologic) tectonic structures cannot correctly represent the current tectonic regime because they were formed before the Cenozoic. In this context, we attempted to construct a seismotectonic province map by using seismic and geophysical information as well as geologic information

    Full Text Available BACKGROUND: Improving the health and well-being of women and children has long been a common goal throughout the world. From 2005 to 2011, Suizhou City had an annual average of 22,405 pregnant and parturient women (1.04% of the population and 98,811 children under 5 years old (4.57% of the population. Understanding the status of maternal and child health care in Suizhou City during such period can provide the local health administrative department valid scientific bases upon which to construct effective policies. METHODS: Various types of annual reports on maternal and child health care were collected and analyzed retrospectively. RESULTS: Mortality rates for infants and children under 5 years showed a declining trend, while the rates of newborn home visiting, maternal health service coverage, and children health systematic management increased annually in Suizhou City from 2005 to 2011. The incidence of birth defect increased from 2.42 ‰ in 2005 to 3.89 ‰ in 2011. The maternal mortality ratio (MMR fluctuated from 8.39/100,000 to 28.77/100,000, which was much lower than the national MMR (30.0/100,000 in 2010. The rates of hospitalized delivery and births attended by trained health personnel for pregnant women increased to more than 90% in the past five years. CONCLUSIONS: The improvements in maternal and child health care work in Suizhou City are worthy of recognition. Thus, the government should continue to increase funding in these areas to promote the complete enhancement of the maternal and child health care system.

    To investigate the characteristics of pesticide poisoning in Jiangsu Province, China, and to provide a scientific basis for developing effective intervention measures and prevention strategies. The data from report cards of pesticide poisoning in Jiangsu Province from 2006 to 2013 were arranged using EXCEL tables, and assessed. Statistical analysis was applied to the epidemiological data using SPSS. From 2006 to 2013, a total of 32672 cases of pesticide poisoning were reported in Jiangsu Province. Most of the cases were caused by non-occupational poisoning (life poisoning) (72.78%). A majority of patients with pesticide poisoning were 35-54 years old (40.85%) or older than 65 years (15.69%). There were more female patients (58.22%) than male patients (41.78%). Among patients with occupational poisoning, male patients (50.90%) were more than female patients. Among patients with non-occupational poisoning, female patients were more than male patients (38.37%). Pesticide poisoning mainly occurred from July to September. The case-fatality rate of occupational poisoning (0.47%) was lower than that of non-occupational poisoning (7.10%). All 13 cities in Jiangsu Province reported cases of pesticide poisoning. There were more cases in the northern regions than in the southern regions. Pesticide poisoning was mainly caused by organophosphorus insecticides including methamidophos, dichlorvos, dimethoate, omethoate, and parathion, which accounted for 65.58%of all cases. Paraquat had the highest case-fatality rate (10.06%) among all pesticides, followed by tetramine (10.00%), dimethoate or omethoate (7.85%), methamidophos (7.79%), and dimehypo (7.68%). Pesticide poisoning cannot be ignored. The management and control should be improved in production and usage of highly toxic pesticides including organophosphorus insecticides, rodenticides, and herbicides. More attention should be paid to the protection of vulnerable groups including women, children, and the elderly.

    Full Text Available Deaths by venomous animals are medical emergencies that can lead to death and thus constitute sanitary problems in some regions of the world. In the South of America, the accidents by these animals are a common sanitary problem especially in warm, tropical or subtropical regions, related with rural work in several countries. Argentina is located in the extreme South of South America and a minor part of the continental surface is in tropical or subtropical regions, where most of the accidents by venomous animals happen. However, in the big cities in the center and South of the country, with no relation to rural work, scorpionism, mostly due to the synanthropic and facultative parthenogenetic scorpion Tityus trivittatus, has become a sanitary problem in the last few decades. This scorpion is present in the biggest cities of Argentina and in the last decades has killed over 20 children in provinces of the center and north of the country, mostly in big cities. In addition, it seems that this species is growing and spreading in new regions of the cities. In this revision, some characteristics of this scorpion regarding its habitat, spreading in Buenos Aires city, combat measures and available treatments are discussed.

    To study the status and source of aluminum (Al) contamination, a total of 21 sampling sites along six rivers near Xi'an City (Shaanxi province, China) were investigated during 2008-2010. The results indicated that the average concentration of total Al (Al(t)) in the six rivers increased by 1.6 times from 2008 to 2010. The spatial distribution of Al(t) concentrations in the rivers near Xi'an City was significantly different, ranged from 367 μg/L (Bahe River) to 1,978 μg/L (Taiping River). The Al(t) concentration was highest near an industrial area for pulp and paper-making (2,773 μg/L), where the Al level greatly exceeded the water quality criteria of both the USA (Criterion Continuous Concentration, 87 μg/L) and Canada (100 μg/L). The average concentration of inorganic monometric aluminum (Al(im)) was 72 μg/L which would pose threats to fishes and other aquatic lives in the rivers. The concentrations of exchangeable Al (Al(ex)) in the sediment of the Taiping River sampled were relatively high, making it to be an alternative explanation of increasing Al concentrations in the rivers near Xi'an City. Furthermore, an increasing Al level has been detected in the upstream watershed near Xi'an City in recent years, which might indicate another notable pollution source of Al.

  3. Uranium provinces and the exploration industry

    1988-01-01

    There is little doubt that exploration by mining companies in established districts or 'provinces' has led to the discovery of substantial additional ore reserves. However, the competition for, and expenses of, land acquisitions in these known districts often prompts companies to search further afield. In some cases, new discoveries can merely be regarded as extensions of known provinces while others are located in completely new areas. Whether the explorers utilized concepts of metallogenic provinces in the course of such discoveries is questionable; rather, they would have sought the particular combinations of geological circumstances required by the model. Once a new deposit is found, however, the concept of a province, whether correct in that situation or not, is usually responsible for stimulating further activity. Recent examples of such behaviour are the Arizona Strip and NE Nebraska (USA) in provincial extensions and Roxby Downs, Lone Gull (NW Territories, Australia) and Lagoa Real (Brazil) in new areas. More routine and scientific application of metallogenic province theory by the uranium exploration industry would require evidence that not only the bulk of the world's uranium reserves but also the majority of the individual world-class deposits fall into geologically definable provinces. Such evidence should include the demonstration that particular areas of the Earth's crust had been enriched in uranium (with or without related elements) and that this enrichment had persisted through periods of crustal reworking and been responsible for concentrations of the metal ore deposits. The evidence described in the volume is critically reviewed in this context. (author). Refs, 4 figs

    To investigate the contamination of zearalenone in food in Shaanxi Province, and to assess the dietary zearalenone exposure and the health risk of intaking zearalenone from corn products for Shaanxi residents. In 2013-2016, samples of five kinds of food including grains, vegetable oil, liquor and infants' food were collected randomly from ten cities, and determined with ultra-performance liquid chromatography. Dietary intake assessment of human exposure to zearalenone was carried out in combination of food consumption data with concentration of zearalenone. 1193 samples were detected zearalenone and the total detection rate was 17. 27%, with the mean value of 13. 5 μg/kg. Among all food samples, oil products were more seriously polluted than other kinds of foods, its detection rate was 79. 37%. And 12 samples of grain products exceed the standard, the exceeding standard rate was 1. 64%, which were all corn products. The level of zearalenone detected in wheat flour, rice, millet, beer and bakery products was low. The overall level of zearalenone contamination inmarket food is common, but corn products may be the severely contaminated foods with zearalenone in Shaanxi Province. The risk assessmentresult suggests that the current dietary intake of zearalenone from corn products in Shaanxi Province has no appreciable effect on health, however, the concentrations of zearalenone in corn products are relatively high, and need to be monitored in the future.

    About 160 samples of coal, corn, capsicum and drinking water were collected from the endemic fluorosis area of Zhenxiong and Weixin County, Zhaotong City of Yunnan Province, to determine the arsenic (As), selenium (Se) and mercury (Hg) content by AAF-800. The study found that the As content in the main coal seam from the Late Permian coal mines in Zhaotong City is 8.84 mg/kg and some civil coal can reach 89.09 mg/kg. The Se and Hg in the coal samples of Late Permian is lower, but Se and Hg are more concentrated in the pyritic coal balls and the pyritic gangue of the coal seam. The As content in corn and capsicum dried by coal-burning is more than 0.7 mg/kg, the natural standard amount of arsenic content permitted in food by China. The Se and Hg content in corn dried by coal-burning is lower than the natural standard of Se and Hg content in food in China but the Se and Hg content of capsicum dried by coal-burning exceeds the amount permitted by the natural standard for food in China. Clay, used as an additive for the coal-burning process and as a binder in making briquettes, contains a high content of As, generally more than 16 mg/kg. However, the Se and Hg content of clay itself are low. The As, Se and Hg content of drinking water are lower than the natural standard of As, Se and Hg content in the drinking water. So, there is high-As content coal and high-As content dried corn and capsicum in the endemic fluorosis area of Zhaotong City of Yunnan Province. The high As content of the dried corn and capsicum might have originated from the high arsenic content of burnt coal and clay. 30 refs., 4 tabs.

    Waste is currently main problem experienced by cities all over the world. The waste has brought negative impacts on public health, environment, development and social of the cities. However, there must be solutions to overcome the piles of waste in case the individual citizens or community-based organization wisely deal with the problem. In the municipal area of Medan in the Province of North Sumatra, there is sort of organization established by community-based organization (CBO) so-called Bank Sampah or Waste Bank which is placed as a flatform for the member to do business of waste materials by collecting them from households around, sorting the materials into waste categories and ended up by purchasing and selling them to make some money. The organization is not merely a flatform for doing a business of waste materials yet the media for other social activities and efforts of reaching social and family welfare. The study is conducted in some sites of such organization activities in the city, and there are some observations of how the community run the business and in the same time arranging other social activities. The study tries to portray the activities and analyzes the means and the significancy of the CBO on reducing waste problems in the city.

    Dengue is endemic and affects people in all Indonesian provinces. Increasing dengue cases have been observed every year in Sukabumi in West Java province. Despite the endemicity, limited data is available on the genetic of dengue viruses (DENV) circulating in the country. To understand the dynamics of dengue disease, we performed molecular and serological surveillance of dengue in Sukabumi. A total of 113 patients were recruited for this study. Serological data were obtained using anti-dengue IgM and IgG tests plus dengue NS1 antigen detection. Dengue detection and serotyping were performed using real-time RT-PCR. Viruses were isolated and the envelope genes were sequenced. Phylogenetic and evolutionary analyses were performed to determine the genotype of the viruses and their evolutionary rates. Real-time RT-PCR detected DENV in 25 (22%) of 113 samples. Serotyping revealed the predominance of DENV-2 (16 isolates, 64%), followed by DENV-1 (5 isolates, 20%), and DENV-4 (4 isolates, 16%). No DENV-3 was detected in the samples. Co-circulation of genotype I and IV of DENV-1 was observed. The DENV-2 isolates all belonged to the Cosmopolitan genotype, while DENV-4 isolates were grouped into genotype II. Overall, their evolutionary rates were similar to DENV from other countries. We revealed the distribution of DENV serotypes and genotypes in Sukabumi. Compared to data obtained from other cities in Indonesia, we observed the differing predominance of DENV serotypes but similar genotype distribution, where the infecting viruses were closely related with Indonesian endemic viruses isolated previously.

    Taking the Dongguan City with rapid urbanization as a case, and selecting landscape ecological security level as evaluation criterion, the urbanization cellular number of 1 km x 1 km ecological security cells was obtained, and imbedded into the transition rules of cellular automata (CA) as the restraint term to control urban development, establish ecological security urban CA, and simulate ecological security urban development pattern. The results showed the integrated landscape ecological security index of the City decreased from 0.497 in 1998 to 0.395 in 2005, indicating that the ecological security at landscape scale was decreased. The CA-simulated integrated ecological security index of the City in 2005 was increased from the measured 0.395 to 0.479, showing that the simulated urban landscape ecological pressure from human became lesser, ecological security became better, and integrated landscape ecological security became higher. CA could be used as an effective tool in researching urban ecological security.

    Full Text Available Although lead recycling activities are a known risk factor for elevated blood levels in South East Asia, little is known regarding the prevalence of and risk factors for elevated blood lead levels (BLL among the general pediatric population in Vietnam. This study is a cross-sectional evaluation of 311 children from Children’s Hospital #2 in Ho Chi Minh City, Vietnam. Capillary blood lead testing was performed using the LeadCare II. Mean BLLs were 4.97 μg/dL (Standard Deviation (SD 5.50, with 7% of the participants having levels greater than 10 μg/dL. Living in Bing Duong province (OR 2.7, 95% CI 1.4–5.6.1 or the Dong Nai province (OR 2.3, 95% CI 1.0–5.1 and having an age greater than 12 months (OR 6.0, 95% CI 3.1–11.8 were associated with higher BLLs. The prevalence of elevated BLLs in Vietnam is consistent with other SE Asian countries. Mean BLLs in Ho Chi Minh City are markedly less than those seen in a separate study of children living near lead recycling activities. Additional evaluation is necessary to better detail potential risk factors if screening is to be implemented within Vietnam.

  14. An allometric scaling relation based on logistic growth of cities

    2014-01-01

    Highlights: • An allometric scaling based on logistic process can be used to model urban growth. • The traditional allometry is based on exponential growth instead of logistic growth. • The exponential allometry represents a local scaling of urban growth. • The logistic allometry represents a global scaling of urban growth. • The exponential allometry is an approximation relation of the logistic allometry. - Abstract: The relationships between urban area and population size have been empirically demonstrated to follow the scaling law of allometric growth. This allometric scaling is based on exponential growth of city size and can be termed “exponential allometry”, which is associated with the concepts of fractals. However, both city population and urban area comply with the course of logistic growth rather than exponential growth. In this paper, I will present a new allometric scaling based on logistic growth to solve the above mentioned problem. The logistic growth is a process of replacement dynamics. Defining a pair of replacement quotients as new measurements, which are functions of urban area and population, we can derive an allometric scaling relation from the logistic processes of urban growth, which can be termed “logistic allometry”. The exponential allometric relation between urban area and population is the approximate expression of the logistic allometric equation when the city size is not large enough. The proper range of the allometric scaling exponent value is reconsidered through the logistic process. Then, a medium-sized city of Henan Province, China, is employed as an example to validate the new allometric relation. The logistic allometry is helpful for further understanding the fractal property and self-organized process of urban evolution in the right perspective

    Dengue is a major global public health problem with increasing incidence and geographic spread. The epidemiology is complex with long inter-epidemic intervals and endemic with seasonal fluctuations. This study was initiated to investigate dengue transmission dynamics in Binh Thuan province, southern Vietnam. Wavelet analyses were performed on time series of monthly notified dengue cases from January 1994 to June 2009 (i) to detect and quantify dengue periodicity, (ii) to describe synchrony patterns in both time and space, (iii) to investigate the spatio-temporal waves and (iv) to associate the relationship between dengue incidence and El Niño-Southern Oscillation (ENSO) indices in Binh Thuan province, southern Vietnam. We demonstrate a continuous annual mode of oscillation and a multi-annual cycle of around 2-3-years was solely observed from 1996-2001. Synchrony in time and between districts was detected for both the annual and 2-3-year cycle. Phase differences used to describe the spatio-temporal patterns suggested that the seasonal wave of infection was either synchronous among all districts or moving away from Phan Thiet district. The 2-3-year periodic wave was moving towards, rather than away from Phan Thiet district. A strong non-stationary association between ENSO indices and climate variables with dengue incidence in the 2-3-year periodic band was found. A multi-annual mode of oscillation was observed and these 2-3-year waves of infection probably started outside Binh Thuan province. Associations with climatic variables were observed with dengue incidence. Here, we have provided insight in dengue population transmission dynamics over the past 14.5 years. Further studies on an extensive time series dataset are needed to test the hypothesis that epidemics emanate from larger cities in southern Vietnam.

    To determine the biodiversity of arenaviruses in China, we captured and screened rodents and shrews in Wenzhou city, Zhejiang province, a locality where hemorrhagic fever diseases are endemic in humans. Accordingly, arenaviruses were detected in 42 of 351 rodents from eight species, and in 12 of 272 Asian house shrews (Suncus murinus), by RT-PCR targeting the L segment. From these, a single arenavirus was successfully isolated in cell culture. The virion particles exhibited a typical arenavirus morphology under transmission electron microscopy. Comparison of the S and L segment sequences revealed high levels of nucleotide (>32.2% and >39.6%) and amino acid (>28.8% and >43.8%) sequence differences from known arenaviruses, suggesting that it represents a novel arenavirus, which we designated Wenzhou virus (WENV). Phylogenetic analysis revealed that all WENV strains harbored by both rodents and Asian house shrews formed a distinct lineage most closely related to Old World arenaviruses. - Highlights: • A novel arenavirus (Wenzhou virus) was identified in Zhejiang province, China. • The virus is highly circulating in five species of rats and one species of shrews • More efforts are needed to infer whether it is pathogenic to humans or not.

    Full Text Available Founded in 438 and included on the World Heritage List in 2003, the ancient city of Derbent emerged in the area which, by the time of its foundation, was known under various names which belong, as it is shown in the paper, to different Bulgar (Turkic languages: province of Chor, Ζουάρ-ος fortress, Chora / Djora way, Τζοΰρ, city of Chora, Chola / Choga / Chol, gate of Chola / Choga, province of Sul. These dialectal place names meaning ʻsteep bank, precipiceʼ meet the localization of the city in a narrow passageway between the Greater Caucasus and the Caspian Sea. The author argues that all etymologies of the considered oikonyms and horonyms based on linguistic data other than Bulgar should be recognized as inadequate. Their Bulgar origin is supported by the toponymic landscape and the names of the peoples who lived within its borders in the early Middle Ages. The existence of toponymic parallels outside the region in question is explained by the migration, in the first centuries AD, of the Bulgars from the North-Eastern Caucasus and Dagestan to Eastern and Southern Europe — the Volga region, the Balkans and Crimea.

    The particle size, total organic carbon (TOC), total nitrogen (TN), C/N ratio and metal concentrations as well as activities of 210Pb were determined in Liaohe River estuary area (LN-2) and Shenyang area (LN-5), and the organic matter resources were discussed in two core sediments. Also the index of geoaccumulation (Igeo) and enrichment factors (EFs) methods were applied to evaluate the state of heavy metal contamination in the studied sties. The study showed that both sediment cores LN-2 and LN-5 were dominated by silts, and the vertical variations of grain-size composition and organic matter were well distributed in LN- 2 while fluctuated in LN-5. According to the organic matter source analysis through C/N ratio, C/N ratio varied in the scale of 5. 24-7.93 in LN-2 which was dominated by river source, and 9.94-14.21 in LN-5 which was dominated by terrestrial input. Al, Ca, Fe, Mn, Ni, Cu, Zn, Cd, Pb and Cr in two sediment cores had different vertical changing rules, Ni and Zn in LN-2 as well as Pb and Zn in LN-5 were affected by both natural and human factors, other elements had similar distributions to those of organic matters, which showed that these elements were mainly affected by the natural activities. Based on Igeo and EFs, both sediment cores were more severely polluted with Ni, Zn and Pb than other metals. The effects of human activities on the environment were also discussed in this study, combined with the economical development of Liaoning Province and the studied sites in the past 20 years.

    Full Text Available Though the greenhouse whitefly, Trialeurodes vaporariorum (Westwood (Hemiptera: Aleyrodidae was introduced into China more than 60 years ago, the genetic diversity and structure of this exotic insect pest and virus vector have not been studied. To investigate the population genetic characteristics of this invasive species and to identify potential invasion routes, the genetic diversity and population structure of 17 collections of T. vaporariorum from nine provinces in China were analyzed using seven microsatellite loci. The results of the analyses indicated that the genetic diversity for the populations examined from the four provinces: Jilin, Ningxia, Guizhou and Qinghai, was lower than the genetic diversity of populations from the five provinces: Yunnan, Shandong, Shanxi, Liaoning, and Gansu. The T. vaporariorum populations analyzed in this study grouped as two distinct genetic clusters based on the analysis using STRUCTURE, whereas, 8 clusters were identified based on the BAPS analysis. Of the 136 genetic distance (Fst values, 128 (94% were associated with a significant exact test. However, there was no significant relationship between Fst and geographical distance. These results demonstrate that populations of T. vaporariorum in China exhibit significant genetic differentiation, indicating the likelihood that multiple introductions of T. vaporariorum into China have occurred. Also, the populations collected from the provinces of Jilin, Ningxia, Guizhou and Qinghai appear to represent secondary introductions originating from other Chinese provinces.

    A probabilistic seismic hazard assessment of the Province of Murcia in terms of peak ground acceleration (PGA) and spectral accelerations [SA( T)] is presented in this paper. In contrast to most of the previous studies in the region, which were performed for PGA making use of intensity-to-PGA relationships, hazard is here calculated in terms of magnitude and using European spectral ground-motion models. Moreover, we have considered the most important faults in the region as specific seismic sources, and also comprehensively reviewed the earthquake catalogue. Hazard calculations are performed following the Probabilistic Seismic Hazard Assessment (PSHA) methodology using a logic tree, which accounts for three different seismic source zonings and three different ground-motion models. Hazard maps in terms of PGA and SA(0.1, 0.2, 0.5, 1.0 and 2.0 s) and coefficient of variation (COV) for the 475-year return period are shown. Subsequent analysis is focused on three sites of the province, namely, the cities of Murcia, Lorca and Cartagena, which are important industrial and tourism centres. Results at these sites have been analysed to evaluate the influence of the different input options. The most important factor affecting the results is the choice of the attenuation relationship, whereas the influence of the selected seismic source zonings appears strongly site dependant. Finally, we have performed an analysis of source contribution to hazard at each of these cities to provide preliminary guidance in devising specific risk scenarios. We have found that local source zones control the hazard for PGA and SA( T ≤ 1.0 s), although contribution from specific fault sources and long-distance north Algerian sources becomes significant from SA(0.5 s) onwards.

This survey was carried out in order to recover the ethnobotanical and ethnomedicinal knowledge of the residents of this province. They are using medicinal and functional plants for treating or preventing several diseases. Materials and Methods: Ethnobotanical data sheets were run with the native inhabitants and people of the province by arranging frequent field trips to different parts of the province and direct interviews with them especially those who were more familiar with the plants and their usage.Results: A total of 150 plant species belonging to 53 families were recorded for their ethnobotanical and ethnomedicinal uses among the people of province. The records were developed by scientific names, family names, local names, medicinal parts used, different ways of their application, and traditional uses of the plants. There was high compliance in the use of plants in painful disorders, gastrointestinal, and dermatological diseases.Conclusion: This study revealed that the people of Hormozgan province have a rich knowledge of natural resources. The use and consumption of medicinal plants are still important parts of their life. Rational use of native medicinal plants may benefit and improve their living standards and quality of life. The results of this study can be used as a basis for selecting herbs for further pharmacological, phytochemical, and pharmacognostical studies.

    This work studies O3 pollution for Chon Buri city in the eastern region of Thailand, where O3 has become an increased and serious concern in the last decade. It includes emission estimation and photochemical box modeling in support of investigating the underlying nature of O3 formation over the city and the roles of precursors emitted from sources. The year 2006 was considered and two single-day episodes (January 29 and February 14) were chosen for simulations. It was found that, in the city, the industrial sector is the largest emissions contributor for every O3 precursor (i.e., NO(x), non-methane volatile organic compounds or NMVOC, and CO), followed by on-road mobile group. Fugitive NMVOC is relatively large, emitted mainly from oil refineries and tank farms. Simulated results acceptably agree with observations for daily maximum O3 level in both episodes and evidently indicate the VOC-sensitive regime for O3 formation. This regime is also substantiated by morning NMVOC/NO(x) ratios observed in the city. The corresponding O3 isopleth diagrams suggest NMVOC control alone to lower elevated O3. In seeking a potential O3 control strategy for the city, a combination of brute-force sensitivity tests, an experimental design, statistical modeling, and cost optimization was employed. A number of emission subgroups were found to significantly contribute to O3 formation, based on the February 14 episode, for example, oil refinery (fugitive), tank farm (fugitive), passenger car (gasoline), and motorcycle (gasoline). But the cost-effective strategy suggests control only on the first two subgroups to meet the standard. The cost of implementing the strategy was estimated and found to be small (only 0.2%) compared to the gross provincial product generated by the entire province where the city is located within. These findings could be useful as a needed guideline to support O3 management for the city. Elevated O3 in the urban and industrial city of Chon Buri needs better

    Background: Both the levels and patterns of outdoor and indoor air pollutants have changed dramatically during the last decade in China. However, few studies have evaluated the effects of the present air pollution on the health of Chinese children. This study examines the association between outdoor and indoor air pollution and respiratory diseases among children living in Liaoning, a heavy industrial province of China. Methods: A cross-sectional study of 23,326 Chinese children aged 6 to 13 years was conducted in 25 districts of 7 cities in Northeast China during 2009. Three-year (2006–2008) average concentrations of particles with an aerodynamic diameter of ≤ 10 μm (PM{sub 10}), sulfur dioxide (SO{sub 2}), nitrogen dioxides (NO{sub 2}), and ozone (O{sub 3}) were calculated from monitoring stations in each of the 25 districts. We used two-level logistic regression models to examine the effects of yearly variations in exposure to each pollutant, controlling for important covariates. Results: The prevalence of respiratory symptoms was higher for those dwelling close to a busy road, those living near smokestacks or factories, those living with smokers, those living in one-story houses typically with small yards, and those with home renovation, bedroom carpet or pets. Ventilation device use was associated with decreased odds of asthma in children. The adjusted odds ratio for diagnosed-asthma was 1.34 (95% confidence interval [CI], 1.24–1.45) per 31 μg/m{sup 3} increase in PM{sub 10}, 1.23 (95%CI, 1.14–1.32) per 21 μg/m{sup 3} increase in SO{sub 2}, 1.25 (95%CI, 1.16–1.36) per 10 μg/m{sup 3} increase in NO{sub 2}, and 1.31 (95%CI, 1.21–1.41) per 23 μg/m{sup 3} increase in O{sub 3}, respectively. Conclusion: Outdoor and indoor air pollution was associated with an increased likelihood of respiratory morbidity among Chinese children. - Highlights: • We studied air pollution and respiratory health in 23,326 Chinese children. • Home renovation, carpet

    Tianshui City is one of the mountainous cities that are threatened by severe geo-hazards in Gansu Province, China. Statistical probability models have been widely used in analyzing and evaluating geo-hazards such as landslide. In this research, three approaches (Certainty Factor Method, Weight of Evidence Method and Information Quantity Method) were adopted to quantitively analyze the relationship between the causative factors and the landslides, respectively. The source data used in this study are including the SRTM DEM and local geological maps in the scale of 1:200,000. 12 causative factors (i.e., altitude, slope, aspect, curvature, plan curvature, profile curvature, roughness, relief amplitude, and distance to rivers, distance to faults, distance to roads, and the stratum lithology) were selected to do correlation analysis after thorough investigation of geological conditions and historical landslides. The results indicate that the outcomes of the three models are fairly consistent.

    Large Igneous Provinces (LIPs) are important features of the Earth history especially recognized during Paleo to Mezosoic times when they are related to the break up of supercontinents (Coffin and Eldhom, 1994). These provinces occur in several different tectonic settings such as volcanic passive margins, submarine ridges and continental and oceanic plateaux. Mafic-dominanted provinces are the most well known among the LIPs and the best examples are the Karoo, Kerguelem and Ontong-Java. LIPs including an important silicic component have been described in some basaltic provinces of southern Africa (Milner et al. 1992). More recently, silicic-dominated LIPs have been recognized in eastern Australia (Bryan et al., 2000), in southern South America (Pankhurst et al. 1998) and in Antartica Penninsula (Riley and Leat, 1999). The common characteristics of this kind of LIP include: 1) large volume of silicic rocks with dominance of ignimbrites, 2) active over 40 to 50 m.y.; and 3) spatially and temporally associated with plate break up. In this paper we present the main geologic and geochronologic characteristics of the Teles Pires volcanic province from southwest Amazon Craton, which allow its classification as a Paleoprotorozoic silicic-dominated LIP. Geologic implications of this suggestion includes the existence of a large cratonic plate as old as 1.81Ga for the Amazon Craton, therefore the proposed 1.85-1.55 Ga magmatic arc of Rio Negro-Juruena Province should be reviewed (au)

    2012-07-01

    CityGML is the international standard of the Open Geospatial Consortium (OGC) for the representation and exchange of 3D city models. It defines the three-dimensional geometry, topology, semantics and appearance of the most relevant topographic objects in urban or regional contexts. These definitions are provided in different, well-defined Levels-of-Detail (multiresolution model). The focus of CityGML is on the semantical aspects of 3D city models, its structures, taxonomies and aggregations, allowing users to employ virtual 3D city models for advanced analysis and visualization tasks in a variety of application domains such as urban planning, indoor/outdoor pedestrian navigation, environmental simulations, cultural heritage, or facility management. This is in contrast to purely geometrical/graphical models such as KML, VRML, or X3D, which do not provide sufficient semantics. CityGML is based on the Geography Markup Language (GML), which provides a standardized geometry model. Due to this model and its well-defined semantics and structures, CityGML facilitates interoperable data exchange in the context of geo web services and spatial data infrastructures. Since its standardization in 2008, CityGML has become used on a worldwide scale: tools from notable companies in the geospatial field provide CityGML interfaces. Many applications and projects use this standard. CityGML is also having a strong impact on science: numerous approaches use CityGML, particularly its semantics, for disaster management, emergency responses, or energy-related applications as well as for visualizations, or they contribute to CityGML, improving its consistency and validity, or use CityGML, particularly its different Levels-of-Detail, as a source or target for generalizations. This paper gives an overview of CityGML, its underlying concepts, its Levels-of-Detail, how to extend it, its applications, its likely future development, and the role it plays in scientific research.

    The aim of this work was to investigate the current situation of Trichinella infection from domestic pigs in the historical endemic areas of Henan province, central China. A total of 823 diaphragm samples from the indoor-raised pigs were collected in five cities of Henan during 2014-2015 and examined by artificial digestion method. The overall prevalence of Trichinella infection in pigs was 0.61 % (5/823). Trichinella larvae were detected in 0.91 % (5/550) of pigs from Nanyang city of Henan. The larval burden in infected animals was 0.03 larvae per gram (lpg) of muscles with a range from 0.02 to 0.05 lpg. The larvae were identified as Trichinella spiralis by multiple PCR. Our study confirms the existence of swine trichinellosis in Henan, but the infection level was under the minimum level for defining infectious sources for humans. However, the prevalence of swine Trichinella infection in Henan need to be further evaluated with a large scale of pork samples for ensuring meat food safety.

    Full Text Available To effectively manage water resources in agricultural production, it is necessary to understand the spatiotemporal variation of the water footprint (WF and the influences of agricultural inputs. Employing spatial autocorrelation analysis and a geographically weighted regression (GWR model, we explored the spatial variations of the WF and their relationships with agricultural inputs from 1998 to 2012 in Northeast China. The results indicated that: (1 the spatial distribution of WFs for the 36 major maize production prefectures was heterogeneous in Northeast China; (2 a cluster of high WFs was found in southeast Liaoning Province, while a cluster of low WFs was found in central Jilin Province, and (3 spatial and temporal differentiation in the correlations between the WF of maize production and agricultural inputs existed according to the GWR model. These correlations increased over time. Our results suggested that localized strategies for reducing the WF should be formulated based on specific relationships between the WF and agricultural inputs.

    Full Text Available This study was conducted to evaluate the incidence of non-typhoidal Salmonella (NTS serotypes in raw and ready-to-eat (RTE broiler products in the North West Province of South Africa. A total of 120 raw broiler samples, 40 samples of polonies and 20 samples of smoked viennas were obtained from retail points in major cities and towns in the province. Samples were subjected to aerobic plate count and later screened for the presence of NTS using phenotypic and genotypic techniques. The average bacterial count in raw products was 3.1 x 105 cfu/g whereas bacterial contamination of RTE products was 1.8 x 103 cfu/g. The average recovery rate of NTS species from raw broiler products was 12.5% and the serotypes identified were S. typhimurium (46.4%, S. enteritidis (30.9% and S. newport (22.9%. No NTS was recovered from the RTE products. However, S. typhimurium was the predominant serotype in whole carcasses whereas S. enteritidis and S. newport were prevalent in chicken parts. Out of the 160 presumptive NTS isolates screened by polymerase chain reaction (PCR, 140 (87.5% were confirmed for the presence of the Salmonella-specific invA gene. In addition, 115 (82.4% of the confirmed isolates harboured the plasmid spvC gene. Random Amplified Polymorphic DNA (RAPD fingerprinting of isolates using RAPD 1 and RAPD 3 primers, revealed some inter- and intra-serotype genetic diversity among isolates, suggesting varying sources of contamination. The results of this study represent the first report on the incidence and prevalent serotypes of NTS in chicken products in the North West Province of South Africa.

    Full Text Available Abstract Background Men who have sex with men (MSM have become one of high-risk population for human immunodeficiency virus (HIV infection, due to their multiple sex partners and unprotected anal intercourse. Promoting HIV testing is an effective strategy for the prevention and control of HIV infection. We assessed the factors associated with a prior HIV testing history, which could provide guidance for implementation of future HIV intervention programs. Methods A cross-sectional study was conducted in three cities of Zhejiang Province, namely, Hangzhou, Ningbo and Wenzhou, using respondent-driven sampling, between December 2013 and June 2014. A face-to-face questionnaire survey was employed to collect relevant information about HIV testing. Univariate and multivariate logistic regression analyses were used to identify the factors associated with a prior HIV testing history. Results The adjusted rate of prior HIV testing among MSM in Zhejiang Province was 55.9 %. The adjusted rates of HIV and syphilis infections among MSM in Zhejiang Province were 14.0 % and 11.4 %, respectively. A weighted multivariate analysis showed that MSM of older age were more likely to be tested, as were MSM with higher level of education, self-reported homosexuality and a higher frequency of receiving AIDS/sexually transmitted infections educational intervention in the past year. MSM with suicidal inclination and self-perceived lower possibility of HIV infection were less likely to report ever having undergone an HIV test. Conclusions The prevalence of prior HIV testing among MSM in Zhejiang Province, China is low. Effective and more frequent interventional measures should be adopted to improve risk awareness and psychosocial support for younger, less educated MSM, and to encourage more MSM to undergo HIV testing.

  2. Cogeneration opportunities in the maritime provinces

    With the arrival of natural gas in New Brunswick in November 1999, the province will be faced with new power generation development opportunities in four different categories of power projects. These include industrial self generation (including cogeneration), merchant power plants, power projects to replace aging facilities, and power projects to help meet future environmental needs. New Brunswick's competitive advantage in harnessing the power generation development opportunities lies in the fact that it is close to major electricity markets in Quebec and New England. It also has many available generation sites. The province's many pulp and paper plants with large process steam needs are also ideal candidates for cogeneration. Some of the major competitive advantages of natural gas over coal are its lower operation and maintenance costs, it is thermally more efficient, produces lower emissions to the environment and prices are competitive. One of the suggestions in New Brunswick Power's new restructuring proposal is to unbundle electricity service in the province into generation and transmission and distribution services. Three gas-fired projects have already been proposed for the province. The 284 MW Bayside Power Project at the Courtenay Bay Generating Station is the most advanced

    Indentifying the spatio-temporal patterns of ecosystem services supply and demand and the driving forces is of great significance to the regional ecological security and sustainable socio-economic development. Due to long term and high-intensity development, the ecological environment in central and southern Liaoning urban agglomerations has been greatly destroyed thereafter has restricted sustainable development in this region. Based on Landsat ETM and OLI images, land use of this urban agglomeration in 2005, 2010 and 2015 was extracted. The integrative index of multiple-ecosystem services (IMES) was used to quantify the supply (IMESs), demand (IMESd) and balance (IMESb) of multiple-ecosystem services, The spatial patterns of ecosystem services and its dynamics for the period of 2005-2015 were revealed. The multiple regression and stepwise regression analysis were used to explore relationships between ecosystem services and socioeconomic factors. The results showed that the IMESs of the region increased by 2.93 %, whereas IMESd dropped 38 %. The undersupplied area was reduced to 2. The IMESs and IMESb were mainly negatively correlated with gross domestic product (GDP), population density, foreign investment and industrial output, while GDP per capita and the number of teachers had significant positive impacts on ecosystem services supply. The positive correlation between IMESd and GDP, population density and foreign investment were found. The ecosystem services models were established. Supply and balance of multiple-ecosystem services were positively correlated with population density, but the demand was the opposite. The results can provide some reference value for the coordinately economic and ecological development in the study area.

  4. Large igneous provinces (LIPs) and carbonatites

    2010-03-01

    There is increasing evidence that many carbonatites are linked both spatially and temporally with large igneous provinces (LIPs), i.e. high volume, short duration, intraplate-type, magmatic events consisting mainly of flood basalts and their plumbing systems (of dykes, sills and layered intrusions). Examples of LIP-carbonatite associations include: i. the 66 Ma Deccan flood basalt province associated with the Amba Dongar, Sarnu-Dandali (Barmer), and Mundwara carbonatites and associated alkali rocks, ii. the 130 Ma Paraná-Etendeka (e.g. Jacupiranga, Messum); iii. the 250 Ma Siberian LIP that includes a major alkaline province, Maimecha-Kotui with numerous carbonatites, iv. the ca. 370 Ma Kola Alkaline Province coeval with basaltic magmatism widespread in parts of the East European craton, and v. the 615-555 Ma CIMP (Central Iapetus Magmatic Province) of eastern Laurentia and western Baltica. In the Superior craton, Canada, a number of carbonatites are associated with the 1114-1085 Ma Keweenawan LIP and some are coeval with the pan-Superior 1880 Ma mafic-ultramafic magmatism. In addition, the Phalaborwa and Shiel carbonatites are associated with the 2055 Ma Bushveld event of the Kaapvaal craton. The frequency of this LIP-carbonatite association suggests that LIPs and carbonatites might be considered as different evolutionary ‘pathways’ in a single magmatic process/system. The isotopic mantle components FOZO, HIMU, EM1 but not DMM, along with primitive noble gas signatures in some carbonatites, suggest a sub-lithospheric mantle source for carbonatites, consistent with a plume/asthenospheric upwelling origin proposed for many LIPs.

    The experiment data used in this paper include CDOM(Chromophoric dissolved organic matter) absorption coefficient, water apparent optical properties and petroleum pollution concentration, which were obtained in May 2008, August 2009 and June 2010 respectively at Liaohe Oilfield in Panjin city, Liaoning province of China. A model between CDOM absorption coefficient and petroleum pollution concentration was developed, and then was applied to eight HJ-1CCD remote sense images obtained from 2009 to 2011, to produce multi-period temporal and spatial distribution maps of petroleum concentration in costal waters. Based on these thematic maps, the dynamic monitoring of petroleum pollution concentration distribution was done. The results showed that (1)There was a decreasing trend of petroleum concentration from costal waters to open sea, which manifest itself as an approximately zonal distribution;(2) due to low precipitation in May and June every year, the concentration of petroleum keeps in a relatively high value state; (3) in September, the concentration of petroleum decreases dramatically as pre increases, most of the area below 0.29 mg/L; (4) compared with that in the same period, the concentration of petroleum in April 2010 is apparently higher than in April 2011, and among the images in September from 2009 to 2011,the highest concentration of petroleum appears in 2010, and the lowest in 2009

    Objective: To understand the status of birth defects among the perinatal infants in the areas contiguous to Hongyanhe nuclear power plant before its normal operation, so as to provide background information for the evaluation of the impact of nuclear power plant on birth defects. Methods: From 1 October 1995 to 30 September 2009 the midwifery units at second class and above of Wafangdian City were asked to be in charge of recording the birth defects among the perinatal infants born during this period within the range of 50 km around the Hongyanhe nuclear power plant. Results: The total number of birth defects was 697, and the maternal number Was 83779. The average defect rate Was 83.20/10 4 . There were significant differences in the birth defect rate among different years (χ 2 =39.54, P<0.05), however, without linear trend therein,and among the survey areas (χ 2 =15.36, P<0.05) as well. The top five birth defects were congenital heart disease (148 cases), cleft lip with cleft palate (67 cases), congenital hydrocephalus (63 cases), and spina bifida (37 cases) and cleft lip (36 cases). Conclusions: The birth defect rate within the range of 50 km around the Hongyanhe nuclear power plant is lower than that of the region of Liaoning Province and the national rate of birth defects.

    Full Text Available Chlamydia spp. are obligate intracellular bacteria distributed all over the world, known to cause various forms of diseases in animals and humans. In the present study, a serological survey was conducted to detect the seroprevalence and risk factors associated with rabbit chlamydiosis in northeast China, including Liaoning province, Jilin province, Heilongjiang province, and Inner Mongolia Autonomous Region. Antibodies to Chlamydia were determined by indirect hemagglutination assay (IHA. The overall seroprevalence was estimated at 17.88% in total of 800 blood samples. The Chlamydia seroprevalence varied in domestic rabbits from different factors, and genders of domestic rabbits were considered as major risk factors associated with Chlamydia infection. Our study revealed a widespread and high prevalence of Chlamydia infection in domestic rabbits in northeast China, with higher exposure risk in female domestic rabbits. These findings suggested the potential importance of domestic rabbits in the transmission of zoonotic Chlamydia infection, and thus Chlamydia should be taken into consideration in diagnosing rabbit diseases. To our knowledge, there is no report of Chlamydia infection in domestic rabbits in China and the results extend the host range for Chlamydia, which has important implications for public health and the local economy.

    SO2 and NO2, the important gaseous precursors of atmospheric fine particles, are closely related to urban air quality. Chengdu located in the western China, is the capital city of Sichuan province. Though Sichuan province is one of four heavily polluted areas in China, the air pollution research in Chengdu is in a relative lack, when compared to developed cities as Beijing, Guangzhou, etc. This paper, based on characteristics of SO2 and NO2 in Chengdu, shows that: the average concentration of SO2, NO2 was 25.29 (mainly in the rage 10-40 ), 64.41 (mainly in the range 30-80 ), respectively. There is a similar annual and seasonal variation for them, yet significant differences in diurnal variation. Except summer, the air condition in Chengdu is seriously affected by SO2 and NO2, while the latter plays a more significant role. Multiple regression has good fitting performance to the diurnal variation in Chengdu. The purification efficiency of precipitation in different magnitude is also discussed.

    Background : Township cadres, considered as basic executors of state policy, play an important role in Chinese society. Their job satisfaction is a vital issue for township management, but there are few studies on this topic in China. The goal of this study is to analyze the relationship between occupational stress and job satisfaction, and to further examine whether psychological capital (PsyCap) can serve as a mediator between stress and job satisfaction in Chinese township cadres. Methods : A cross-sectional survey was carried out during the period of from October 2015 to January 2016 in Liaoning Province of China. The questionnaires, which consisted of an effort-reward imbalance scale, Minnesota Satisfaction Questionnaire (MSQ) for job satisfaction, and the psychological capital questionnaire (PCQ-24), as well as questions about demographic characteristics, were distributed to 1800 township cadres and complete responses were received from 1525 participants. Structural equation modeling was used to examine the role that psychological capital played in mediating between occupational stress and job satisfaction. Results : In the present study, effort-reward ratio (ERR= 11 × effort/6 × reward) was negatively associated with job satisfaction (r = -0.372, p stress and job satisfaction. Conclusions : Psychological capital partially mediated the relationship between job stress and job satisfaction among Chinese township cadres. Interventions to improve Chinese township cadres' job satisfaction should be developed in the future, especially the enhancement of PsyCap. Interventions need to be verified in further cohort studies. At present, we are only proposing a theoretical model. Intervention effects need to be validated in further cohort studies.

    The principal characteristics of the Brazil-Angola Alkaline Carbonatite Province are defined and described with specific reference to tectonic setting and economic aspects. The economic aspects of the Brazilian uranium deposits are emphasised. The Brazil-Angola Alkaline-Carbonatite Province can be divided into six Brazilian sub-provinces and two Angolan sub-provinces. Correlation between the sub-provinces of Brazil and Angola remains speculative due to the lack of detailed information, especially age determinations on the Angolan rocks. However, an analysis of the tectonic and petrochemical aspects suggests that the two Brazilian sub-provinces situated along the littoral of Rio de Janeiro/ Sao Paulo and around the periphery of the Parana Basin may be more easily comparable to the two Angolan sub-provinces than the remaining four.

    A crust-upper mantle configuration is proposed for the Tharsis province of Mars which is isostatic and satisfies the observed gravity data. The model is that of a low density upper mantle compensating loads at both the surface and crust-mantle boundary. Solutions are found for lithospheric thickness greater than about 300 km, for which the stress differences are less than 750 bars. This model for Tharsis is similar to the compensation mechanism under the Basin and Range province of the western United States. These provinces also compare favorably in the sense that they are both elevated regions of extensional tectonics and extensive volcanism

    High groundwater nitrate-N is a serious problem especially in highly active agricultural areas. In study, the concentration and spatialtemporal distribution of groundwater nitrate-N under cropland in Shandong province were assessed by statistical and geostatistical techniques. Nitrate-N concentration reached a maximum of 184.60 mg L-1 and 29.5% of samples had levels in excess of safety threshold concentration (20 mg L-1). The median nitrate-N contents after rainy season were significantly higher than those before rainy season, and decreased with increasing groundwater depth. Nitrate-N under vegetable and orchard area are significantly higher than ones under grain. The kriging map shows that groundwater nitrate-N has a strong spatial variability. Many districts, such as Weifang, Linyi in Shandong province are heavily contaminated with nitrate-N. However, there are no significant trends of NO3 --N for most cities. Stepwise regression analysis showed influencing factors are different for the groundwater in different depth. But overall, vegetable yield per unit area, percentages of orchard area, per capita agricultural production, unit-area nitrogen fertilizer, livestock per unit area, percentages of irrigation areas, population per unit area and annual mean temperature are significant variables for groundwater nitrate-N variation.

    Full Text Available Introduction: Stock shortage is one of the development impasses in developing countries and trough it the agriculture sector has faced with the most limitation. The share of Iran’s agricultural sector from total investments after the Islamic revolution (1979 has been just 5.5 percent. This fact causes low efficiency in Iran’s agriculture sector. For instance per each 1 cubic meter of water in Iran’s agriculture sector, less that 1 kilogram dry food produced and each Iranian farmer achieves less annual income and has less mechanization in comparison with similar countries in Iran’s 1404 perspective document. Therefore, it is clear that increasing investment in agriculture sector, optimize the budget allocation for this sector is mandatory however has not been adequately and scientifically revised until now. Thus, in this research optimum budget allocation of Iran- Khorasan Razavi province agriculture sector was modeled. Materials and Methods: In order to model the optimum budget allocation of Khorasan Razavi province’s agriculture sector at first optimum budget allocation between agriculture programs was modeled with compounding three indexes: 1. Analyzing the priorities of Khorasan Razavi province’s agriculture sector experts with the application of Analytical Hierarchy Process (AHP, 2. The average share of agriculture sector programs from 4th country’s development program for Khorasan Razavi province’s agriculture sector, and 3.The average share of agriculture sector programs from 5th country’s development program for Khorasan Razavi province’s agriculture sector. Then, using Delphi technique potential indexes of each program was determined. After that, determined potential indexes were weighted using Analytical Hierarchy Process (AHP and finally, using numerical taxonomy model to optimize allocation of the program’s budget between cities based on two scenarios. Required data, also was gathered from the budget and planning

    A high resolution regional emission inventory of typical primary air pollutants (PAPs) for the year 2012 in Beijing and the surrounding five provinces (BSFP) of North China is developed. It is compiled with the combination of bottom-up and top-down methods, based on city-level collected activity data and the latest updated specific emission factors for different sources. The considered sources are classified into 12 major categories and totally 36 subcategories with respect to their multi-dimensional characteristics, such as economic sector, combustion facility or industrial process, installed air pollution control devices, etc. Power plant sector is the dominant contributor of NOX emissions with an average contribution of 34.1%, while VOCs emissions are largely emitted from industrial process sources (33.9%). Whereas, other stationary combustion sources represent major sources of primary PM2.5, PM10 and BC emissions, accounting for 22.7%, 30.0% and 33.9% of the total emissions, respectively. Hebei province contributes over 34% of the regional total CO emissions because of huge volume of iron and steel production. By comparison, Shandong province ranks as the biggest contributor for NOX, PM10, PM2.5, SO2, VOCs and OC. Further, the BSFP regional total emissions are spatially distributed into grid cells with a high resolution of 9 km × 9 km using GIS tools and surrogate indexes, such regional population, gross domestic product (GDP) and the types of arable soils. The highest emission intensities are mainly located in Beijing-Tianjin-Tangshan area, Jinan-Laiwu-Zibo area and several other cities such as Shijiazhuang, Handan, and Zhengzhou. Furthermore, in order to establish a simple method to estimate and forecast PAPs emissions with macroscopic provincial-level statistical parameters in China, multi-parameter regression equations are firstly developed to estimate emissions outside the BSFP region with routine statistics (e.g. population, total final coal consumption

    In August 2016, a yellow vein disease was observed on leaves of Euonymus bungeanus Maxim (Euonymus, Celastraceae) in Liaoning, China. Virions measuring 750 × 13 nm were observed in a sample from the diseased plant. A potexvirus was detected in the sample by small-RNA deep sequencing analysis and recovered by traditional cloning. The genome of this potexvirus consists of 7,279 nucleotides, excluding the poly(A) tail at the 3' end, and contains five open reading frames (ORFs). Based on the nucleotide and amino acid sequences of the coat protein gene, the virus shared the highest sequence similarity with white clover mosaic virus (WCMV, X16636) (40.1%) and clover yellow mosaic virus (ClYMV, D00485) (37.1%). Phylogenetic analysis showed that the virus clustered with potexviruses and is most closely related to strawberry mild yellow edge virus. These results indicate that this virus is a distinct member of the genus Potexvirus, for which the name euonymus yellow vein associated virus (EuYVAV) is proposed. To our knowledge, this is the first report of a potexvirus on E. bungeanus.

    Borujerd and Aleshtar cities, and as we go south, the planting date postponed. The beginning of the cultivation is a function of temperature, so that the latest planting date was observed in Poldokhtar city as the warmest region of the province. In the observation period, the latest harvesting date was observed in Aligoodarz and Aleshtar cities and the earliest harvesting date was observed in Poldokhtar city. In the forecast period, the beginning of crop cultivation did not change much and remained constant for less than 10 days compared to the observation period. However, many changes occurred in the harvesting date. So that the most changes with 60 days earlier occurred at the Poldokhtar city. The duration of the growth period reduced at all the stations. The greatest reduction in the duration of the growth period was observed at the Aligudarz city with 62 days. The decreasing duration of the growth period was due to changes in temperature and precipitation. This shows that the fall precipitation, which is related to the cold season, does not change much, but the precipitation of the warm season decreases. One of the limitations of rainfed barley cultivation in Lorestan province is temperature in the tillering stage. This restriction will continue in future. In the observation period, temperature of flowering and grain filling period was in optimal conditions, but in the forecast period, with increasing temperature, we will encounter high temperature stress in these two stages. The adaptation strategies are different depending on the type of farming and the climate change scenario. Among these strategies we can mention changes in planting date and crop rotation, use of resistant varieties to the warm conditions and irrigation management. Conclusion The results showed that at all stations, the planting date will be earlier and the duration of the growth period will decrease in the period 2011–2030.

    Full Text Available RACT Protein consumption level of society in Yogyakarta Province has yet to meet the target, but the beef is a source of animal protein that is easily obtainable. Therefore, research on the analysis of demand for beef in this province needs to be done. Objective: (1 Determine the factors that affect the demand for beef in Yogyakarta. (2 Determine the own price elasticity and income elasticity of demand for beef in this province, and to know the cross-price elasticity of demand for beef to changes in the price of mutton, chicken, rice, and cooking oil. Metode: descriptive statistics, followed by inductive statistics , and hypothesis testing. The data used are primary and secondary data. Data were analyzed by multiple linear regression with the value of t and F tests, and analysis of the coefficient of determination. Results: Taken together, the factors that affect the demand for beef in the province is the price of beef, mutton, chicken, rice, cooking oil, income, number of inhabitants. Individually, beef demand is influenced by the price of beef and income residents. Beef inelastic demand means that beef is the daily necessities that are affordable and easy to obtain population of Yogyakarta Province. The increase in income population does not add to demand for beef. Substitutes of beef in the province is goat and chicken, while the complementary goods are rice and cooking oil.

  6. Influence of exposure differences on city-to-city heterogeneity ...

    Science.gov (United States)

    Multi-city population-based epidemiological studies have observed heterogeneity between city-specific fine particulate matter (PM2.5)-mortality effect estimates. These studies typically use ambient monitoring data as a surrogate for exposure leading to potential exposure misclassification. The level of exposure misclassification can differ by city affecting the observed health effect estimate. The objective of this analysis is to evaluate whether previously developed residential infiltration-based city clusters can explain city-to-city heterogeneity in PM2.5 mortality risk estimates. In a prior paper 94 cities were clustered based on residential infiltration factors (e.g. home age/size, prevalence of air conditioning (AC)), resulting in 5 clusters. For this analysis, the association between PM2.5 and all-cause mortality was first determined in 77 cities across the United States for 2001–2005. Next, a second stage analysis was conducted evaluating the influence of cluster assignment on heterogeneity in the risk estimates. Associations between a 2-day (lag 0–1 days) moving average of PM2.5 concentrations and non-accidental mortality were determined for each city. Estimated effects ranged from −3.2 to 5.1% with a pooled estimate of 0.33% (95% CI: 0.13, 0.53) increase in mortality per 10 μg/m3 increase in PM2.5. The second stage analysis determined that cluster assignment was marginally significant in explaining the city-to-city heterogeneity. The health effe

    The Mason City quadrangle covers 6900 miles of the northern Midwestern Physiographic Province in northern Iowa and southern Minnesota. The surface is largely covered by Quaternary glacial and related deposits. The subglacial surface is exposed only in the northeast and is composed of thin Mesozoic and Paleozoic sediments overlying Precambrian basement. A search of available literature revealed no known uranium deposits. A total of 89 uranium anomalies were detected and briefly described in this report. None were considered significant, and all appear to be related to cultural features. Concentrations of K, U, and T are extremely low throughout the quadrangle. Magnetic data appear to illustrate complexities in the underlying Precambrian

After morphological identification and DNA extraction, designing specific primer were used to amplification of ITS1, 5.8s and ITS2 regions, 50 samples were conducted to sequence, randomly. Result: Using morphometric characters 99.14% and 0.86% of isolates identified as F. hepatica and F. gigantica, respectively. PCR amplification of 1081 bp fragment and sequencing result showed 100% similarity with F. hepatica in ITS1 (428 bp), 5.8s (158 bp), and ITS2 (366 bp) regions. Sequence comparison among current study sequences and GenBank data showed 98% identity with 11 nucleotide mismatches. However, in phylogenetic tree F. hepatica sequences of West Azerbaijan Province, Iran, were in a close relationship with Iranian, Asian, and African isolates. Conclusions: Only F. hepatica species is distributed among sheep and cattle in West Azerbaijan Province Iran. However, 5 and 6 bp variation in ITS1 and ITS2 regions, respectively, is not enough to separate of Fasciola spp. Therefore, more studies are essential for designing new molecular markers to correct species identification.

    Although adverse effects of high temperature on mortality have been studied extensively in urban areas, little is known of the heat-mortality associations outside of cities. We investigated whether heat-mortality associations differed between urban and nonurban areas and how urbanicity affected the vulnerability to heat-related mortality. We first analyzed heat-related mortality risk in each of 102 counties in Jiangsu Province, China, during 2009-2013 using a distributed-lag nonlinear model. The county-specific estimates were then pooled for more urban (percentage of urban population ≥ 57.11%) and less urban (percentage of urban population risk comparing the 99th vs. 75th percentiles of temperature was 1.43 [95% posterior intervals (PI): 1.36, 1.50] in less urban counties and 1.26 (95% PI: 1.23, 1.30) in more urban counties. The heat effects on cardiorespiratory mortality followed a similar pattern. Higher education level and prevalence of air conditioning were significantly associated with counties having lower risks, whereas percentage of elderly people was significantly associated with increased risks. Our findings reveal that nonurban areas have significant heat-related mortality risks in Jiangsu, China. These results suggest the need for enhanced adaptation planning in Chinese nonurban areas under a changing climate. Citation: Chen K, Zhou L, Chen X, Ma Z, Liu Y, Huang L, Bi J, Kinney PL. 2016.

    The Chinese province of Shandong, and more particularly its cities Dezhou, Jinan and Rizhao, have established an international reputation of being hotbeds for solar water heating (SWH) technology development and dissemination. The article aims to unveil the evolution of this innovative environment by applying the Functions of Innovation Systems (FIS) approach to the Chinese province of Shandong. It examines the actors, institutions and policy instruments that shape Shandong's innovation system for SWH, the dominant drivers and barriers during the evolution of the TIS and also assesses the applicability of the IS approach to China. It appears that the presence of influential interest organizations and proactive support from local governments have acted as strong drivers for the emergence of Shandong's innovation system for SWHs. On the other hand, the lack of adequate personnel and an overreliance on government policies act as main barriers. With regard to the Chinese specificities potentially detracting from the relevance of applying IS theory to China, we did not find that the central government acted as an initiator of innovation nor that state-owned enterprises had dominant positions in the market. In this innovative industry the impetus for development came from the bottom up and from private corporations. - Highlights: • Application of the functions of innovation systems framework to Chinese province. • Analysis of the evolution of Shandong's solar water heating industry and market. • Local governments and interest organizations make innovation environment successful. • Bottom-up development and dissemination of renewable energy in China.

    According to the major pollution sources of urban water environment, 10 indexes such as industrial sewage quantity were closen to establish evaluation indexes system about the types and influencing factors of the typical and medium-small-sized cities in the southern China. Case studies of 16 typical and medium-small-sized cities were taken in Jiangsu, Zhejiang, Hubei and Anhui provinces. Combined with SPSS 11.0 cluster analysis results, city types were divided in reference to the values of water resources comprehensive pollution indexes and economical development indexes. The driving forces about city water environment pollution were studied by principal component analysis method. The result indicates that the 16 cities belong to two categories and four sub-categories, which are rich economy as well as light pollution of water environment and poor economy as well as heavy pollution of water environment. The influencing factors of water environment pollution are in sequence of industrial water pollution, agricultural no-point source pollution and urban domestic water pollution. The main factors of water environment pollution influenced I category cities, II as well as IV category cities and III category cities are industrial water pollution, urban domestic pollution and agricultural no-point source pollution respectively.

    In 2009, China implemented the National Essential Medicines System (NEMS) to improve access to high-quality low-cost essential medicines. To measure the prices, availability and affordability of medicines in China following the implementation of the NEMS. 120 public hospitals and 120 private pharmacies in ten cities in Shaanxi Province, Western China. The standardized methodology developed by the World Health Organization and Health Action International was used to collect data on prices and availability of 49 medicines. Median price ratio; availability as a percentage; cost of course of treatment in days' wages of the lowest-paid government workers. In the public hospitals, originator brands (OBs) were procured at 8.89 times the international reference price, more than seven times higher than the lowest-priced generics (LPGs). Patients paid 11.83 and 1.69 times the international reference prices for OBs and generics respectively. A similar result was observed in the private pharmacies. The mean availabilities of OBs and LPGs were 7.1 and 20.0 % in the public hospitals, and 12.6 and 29.2 % in the private pharmacies. Treatment with OBs is therefore largely unaffordable, but the affordability of the LPGs is generally good. High prices and low availability of survey medicines were observed. The affordability of generics, but not OBs, is reasonable. Effective measures should be taken to reduce medicine prices and improve availability and affordability in Shaanxi Province.

    The Elk City quadrangle in north central Idaho and western Montana lies within the Northern Rocky Mountain province. The area is dominated by instrusives of the Idaho and Sawtooth Batholiths, but contains significant exposures of Precambrian metamorphics and Tertiary volcanics. Magnetic data apparently show some expression of the intrusives of the Idaho Batholith. Areas of faulted Precambrian and Tertiary rocks appear to express themselves as well defined regions of high frequency and high amplitudes wavelengths. The Elk City quadrangle has been unproductive in terms of uranium mining, though it contains significant exposures of the Challis Formation, which has been productive in other areas south of the quadrangle. A total of 238 anomalies are valid according to the criteria set forth in Volume I of this report. These anomalies are scattered throughout the quadrangle. The most distinctive group of anomalies with peak apparent uranium concentrations of 10.0 ppM eU or greater

    Full Text Available Against the background of global warming, China has vowed to meet a series of carbon emissions reduction targets and plans to launch a national carbon emissions rights trading market by 2017. Therefore, from the provincial value chain perspective, using input-output tables from China in 2002, 2007, and 2010, this study constructs models to calculate the CO2 emissions responsibility of each province under the production, consumption, and value capture principles, respectively. Empirical results indicate that Shandong, Hebei, Jiangsu, Guangdong, and Henan bear the most responsibility for CO2 emissions under the three principles in China, while Hainan and Qinghai have the least responsibility. However, there is a great difference in the proportion of carbon emissions responsibility for each province during the same period under different principles or different periods under the same principle. For consumption-oriented areas such as Beijing, Tianjin, Zhejiang, Shanghai, and Guangdong, the production principle is more favorable, and the consumption principle is more beneficial for production-oriented provinces such as Hebei, Henan, Liaoning, Shanxi, Inner Mongolia, and Shaanxi. However, the value capture principle strikes a compromise of the CO2 emissions responsibility of each province between the production and consumption principles, and it shares the CO2 emissions responsibility based on the actual value captured by each province in the provincial value chain. The value capture principle is conducive to the fair and reasonable division of CO2 emissions rights of each province by sectors, as well as the construction of a standardized carbon emissions rights trading market.

    In the People's Republic of China (P.R.C.), the pervasive use of soft coal leads to situations where the concentrations of SO2 and particulate matter approach or surpass those historically observed in London. A cooperative investigation of the effects of air pollution upon the lung function of children in five Chinese cities has been developed among China EPA, U.S. EPA and Robert Wood Johnson Medical School. The paper presents initial results of a winter air pollution field study conducted in Wuhan, one of the selected cities. A 2-week intensive ambient aerosol study was conducted in December 1988 in Wuhan (Hubei Province), a city of nearly 2 million located on the Yangtze River in central China (P.R.C.). This is an industrial region where soft coal burning is widespread, and emission controls for vehicles and industrial facilities are minimal. The sampling site was located in one of the civic centers where residential and commercial density is highest. The purpose of this initial intensive study period was to obtain information on the chemical and physical characteristics of the aerosol species in the urban P.R.C. setting. The focus was the composition and acidity of fine particulate material

    Full Text Available Being bordered by the South China Sea and with long coastline, the coastal zone of Guangdong Province is often under severe risk of storm surges, as one of a few regions in China which is seriously threatened by storm surges. This article systematically analyzes the vulnerability factors of storm surges in the coastal area of Guangdong (from Yangjing to Shanwei. Five vulnerability assessment indicators of hazard-bearing bodies are proposed, which are social economic index, land use index, eco-environmental index, coastal construction index, and disaster-bearing capability index. Then storm surge vulnerability assessment index system in the coastal area of Guangdong is established. Additionally, the international general mode about coastal vulnerability assessment is improved, and the vulnerability evolution model of storm surges in the coastal area of Guangdong is constructed. Using ArcGIS, the vulnerability zoning map of storm surges in the study region is drawn. Results show that there is the highest degree of storm surge vulnerability in Zhuhai, Panyu, and Taishan; second in Zhongshan, Dongguan, Huiyang, and Haifeng; third in Jiangmen, Shanwei, Yangjiang, and Yangdong; fourth in Baoan, Kaiping, and Enping; and lowest in Guangzhou, Shunde, Shenzhen, and Longgang. This study on the risk of storm surges in these coastal cities can guide the land use of coastal cities in the future, and provide scientific advice for the government to prevent and mitigate the storm surge disasters. It has important theoretical and practical significance.

    As one of the key topics in the research of landscape ecology, regional ecological security patterns can effectively promote regional sustainable development and terrestrial ecological barriers construction. It is extremely important for middle Yunnan, with frequent disasters and fragile ecolo-gical environment, to construct ecological security patterns so as to effectively avoid the geological disasters, maintain ecosystem health, and promote the coordinated development of regional ecological system and social economic system. Taking Yuxi City as a case study area, this study firstly estimated the ecosystem services importance of water conservation, carbon fixation and oxygen release, soil conservation, and biodiversity according to the basal characteristics of regional ecological environment, and then identified ecological sources in consideration of the quality of integrated ecosystem services and single types. Secondly, the resistance surface based on land use types was modified by the sensitivity of regional geological disasters. Lastly, the ecological corridors were identified using minimum cumulative resistance model, and as a result, the ecological security pattern of Yuxi City was constructed. The results showed that there were 81 patches for ecological sources in Yuxi City, accounting for 38.4% of the total area, and overlaying 75.2% of nature protection areas. The ecological sources were mainly distributed in the western mountainous areas as well as eastern water areas of the city. The length of ecological corridors was 1642.04 km, presenting a spatial pattern of one vertical and three horizontals, and extending along river valleys and fault basins with high vegetation coverage. This paper constructed ecological security patterns in mountainous areas aiming at the characteristics of geological disasters, providing spatial guidance for development and conservation decision-making in mountain areas.

    The bombing of the Novi Sad Oil Refinery in 1999 has lead to soil pollution by the products of burning oil and oil derivatives. These products were first carried by winds to the Rimski Sancevi Experiment Field of the Institute of Field and Vegetable Crops (located in the vicinity of the Novi Sad Oil Refinery), where they entered the soil via precipitation. Later, they spread to the city of Novi Sad, its vicinity, and the whole of the Vojvodina province, contaminating the soil. In the present study, we examined the extent to which this soil had been polluted. In 1999, we began to study the level of soil contamination at the Institute's Experiment Field at Rimski Sancevi. In 2000, we carried out the same kind of study in and around the city of Novi Sad, while in 2001 we expanded the study to the whole of Vojvodina. The studies' findings show that the soil reaction has not changed and that the levels of heavy metals in the soil have not exceeded the maximum tolerable concentration (MTC). The presence of PAHs at various concentrations was detected, however. This presence is a result of the fires at the Novi Sad Oil Refinery. (author)

    Surabaya is the second largest city in Indonesia and the capital of East Java Province with rapid population and industrialization. The impact of urbanization in the big city can suffer potential disasters either nature or anthropogenic such as land subsidence and flood. The pattern of land subsidence need to be mapped for the purposes of planning and structuring the city as well as taking appropriate policy in anticipating and mitigating the impact. This research has used interferometric Synthetic Aperture Radar (InSAR) Small Baseline Subset (SBAS) technique and applied time series analysis to investigate land subsidence occured. The technique includes the process of focusing the SAR data, incorporating the precise orbit, generating interferogram and phase unwrapping using SNAPHU algorithms. The results showed land subsidence has been detected during 2014-2017 over Surabaya city area using ALOS-2/PALSAR-2 images data. These results reveal the subsidence has observed in several area in Surabaya in particular northern part reach up to ∼2 cm/year. The fastest subsidence occurs in highly populated areas suffer vulnerable to flooding and sea level rise impact. In urban areas we found a correlation between land subsidence with residential or industrial land use. It concludes that land subsidence is mainly caused by ground water consumption for industrial and residential use respectively.

    Beta-thalassemia is among the most common genetic disorders in the world and in Iran, with widespread occurrence. A cross-sectional study on 648 beta-thalassemia patients in Shiraz, Iran was carried out to determine the demography of beta-thalassemia major in Shiraz city, Fars province, Iran and also the rate of consanguinity and the significance of pre-marriage counseling in decreasing familial marriages and consequently preventing this autosomal recessive genetic disease. All interviewed patients had thalassemia major and their age, sex, and the consanguinity between parents were recorded. 40.6% of beta-thalassemia patients were outcomes of first-cousin marriages. Comparison of the percentages of familial marriages (consanguinity) between parents of beta-thalassemia patients and a sample of normal population, revealed a statistically significant difference (pmarriages among thalassemic families, however, more education and awareness of young women and men about the increased risk of beta-thalassemia after familial marriage through pre-marriage counseling is still necessary.

    An investigational study was conducted of the project for energy conservation and greenhouse effect gas reduction by introducing the energy utilization system combined with CCS equipment and cogeneration system to general industry plants at the industrial complex in Namping City, Fujian Province, China. As a result of the field survey, it was concluded that the capacity suitable for CCS center was 200,000 t/y and the size suitable for pulverized coal boiler at each site was 35 t/h. The energy conservation amount in this project was the coal use reduction amount by 88,000 t/y (48,000 toe/y), and the greenhouse effect gas reduction amount was approximately 90,000 t-CO2/y. As to the economical efficiency of the project, the period of ROI was about 5.1 years, and the internal earning rate at each site was 14-23%. The materialization of the project was confirmed. However, in the case of raising the required funds from city banks in China, financing conditions are strict, and the financing seems to be difficult at each site. It is necessary to raise low-interest funds such as the special environment yen credit. (NEDO)

    Utilizing low-grade waste heat from industries to heat and cool homes and businesses through fourth generation district energy systems (DES) is a novel strategy to reduce energy use. This paper develops a generalizable methodology to estimate the energy saving potential for heating/cooling in 20 cities in two Chinese provinces, representing cold winter and hot summer regions respectively. We also conduct a life-cycle analysis of the new infrastructure required for energy exchange in DES. Results show that heating and cooling energy use reduction from this waste heat exchange strategy varies widely based on the mix of industrial, residential and commercial activities, and climate conditions in cities. Low-grade heat is found to be the dominant component of waste heat released by industries, which can be reused for both district heating and cooling in fourth generation DES, yielding energy use reductions from 12%-91% (average of 58%) for heating and 24%-100% (average of 73%) for cooling energy use in the different cities based on annual exchange potential. Incorporating seasonality and multiple energy exchange pathways resulted in energy savings reductions from 0%-87%. The life-cycle impact of added infrastructure was small (<3% for heating) and 1.9% ~ 6.5% (cooling) of the carbon emissions from fuel use in current heating or cooling systems, indicating net carbon savings. This generalizable approach to delineate waste heat potential can help determine suitable cities for the widespread application of industrial waste heat re-utilization.

  14. Branding Cities, Changing Societies

    DEFF Research Database (Denmark)

    Ooi, Can-Seng

    Societal changes are seldom discussed in the literature on city branding. The time element is important because it highlights the fluctuating reality of society. The city brand message freezes the place but in fact, the city branding exercise is a continuous process. Society emerges too. City...... brands are supposed to accentuate the uniqueness of the city, be built from the bottom-up and reflect the city's identity. This paper highlights three paradoxes, pointing out that city branding processes can also make cities more alike, bring about societal changes and forge new city identities. A city...... branding campaign does not just present the city, it may change the city. The relationships between the branding exercise and the city are intertwined in the evolution of the place....

    2016-10-01

    Smart cities present a substantial growth opportunity in the coming years. The role of GIS in the smart city ecosystem is to integrate different data acquired by sensors in real time and provide better decisions, more efficiency and improved collaboration. Semantically enriched vision of GIS will help evolve smart cities into tomorrow's much smarter cities since geospatial/location data and applications may be recognized as a key ingredient of smart city vision. However, it is need for the Geospatial Information communities to debate on "Is 3D Web and mobile GIS technology ready for smart cities?" This research places an emphasis on the challenges of virtual 3D city models on the road to smarter cities.

  20. Political Ideology and Economic Freedom across Canadian Provinces

    DEFF Research Database (Denmark)

    Bjørnskov, Christian; Potrafke, Niklas

    This paper examines how political ideology influenced economic freedom in the Canadian provinces. We analyze the dataset of economic freedom indicators compiled by the Fraser Institute in 10 Canadian provinces over the 1981-2005 period and introduce two different indices of political ideology......: government and parliament ideology. The results suggest that government ideology influenced labor market reforms: market-oriented governments promoted liberalization of the labor market. Parliamentary ideology did not influence economic liberalization at all. This finding (1) identifies differences between...... leftist and rightwing governments concerning the role of government in the economy and (2) indicates that ideological polarization concerns governments but less parliamentary fractions in the Canadian provinces. ...

    2013-07-01

    Full Text Available Background: In April 2013, a hospital in Suzhou City notified authorities of a patient with nitrite poisoning with two other family members who had similar toxic symptoms five days prior. We investigated the event to identify the cause, source and possible route of contamination. Methods: A case was defined as any person living in the Yang Shan Hua Yuan community who had been diagnosed with cyanoderma and food poisoning symptoms from 15 to 25 April 2013. Active case finding was conducted by interviewing community residents and reviewing medical records from local clinics; information was then retrospectively collected on the patient’s food history, cooking procedures and food sources. Results: We identified three nitrite poisoning cases, one male and two females, from the same family. The time between dinner and onset of illness was less than an a hour. A retrospective survey showed that a substance presumed to be sugar mixed with asparagus on 17 April and with stir-fried asparagus on 21 April wasthe suspected contaminant. The presumed sugar came from a clean-up of a neighbouring rental house. Nitrite was detected in a vomitus sample, the sugar substance and two leftover food samples. Conclusion: This family cluster of nitrite poisoning resulted from the mistaken use of nitrite as sugar to cook dishes. We recommend that sodium nitrite be dyed a bright colour to prevent such a mistake and that health departments strengthen food hygiene education to alert people about the danger of eating unidentified food from an unknown source.

    Full Text Available Schistosomiasis (SCH in The Philippines is caused by Schistosoma japonicum and remains endemic in 28 provinces in 12 regions. Effective SCH control requires describing areas at risk where control efforts may be focused. This study aims at demonstrating the utility of geographical information system (GIS as a tool for SCH surveillance in the province of Davao del Norte. Qualitative and quantitative data on SCH determinants, obtained from local government offices, partner agencies and institutions, were standardised, formatted and incorporated into a GIS map. Atrisk areas are described in terms of determinants and (variables, which included geography and climate (topography, temperature and flood-prone areas, agriculture (irrigation and land use, poverty (percentage of households with income below the poverty threshold, sanitation level (percentage of households with sanitary toilets, intermediate and reservoir hosts (presence of snail colonies and reservoir hosts as well as prevalence and treatment coverage. Endemic villages (barangays were generally found to be located in flood-prone areas in the lowlands near major rivers. New Corella has the highest poverty index among the SCH-endemic areas studied as well as the highest number of confirmed snail colonies. Among known endemic localities in Davao del Norte, Tagum City was found to be the only city meeting the poverty index target of <16.6%. Clustering of SCH cases were reported in six barangays ranging from 0.48% (8 out of 1,655 in Braulio Dujali to 2% (25 out of 1,405 in Asuncion. This study demonstrates the utility of GIS in predicting and assessing SCH risk, which allows prioritisation and allocation of control resources and delivery of services in areas at the highest risk for SCH.

    2017-09-01

    Full Text Available Introduction: Insects as the largest category of arthropods include numerous groups and families that the most important of them belong to order Diptera, family Culicidae. Because of feeding on the human's blood, a number of species of this family have been known as responsible for the transmission of pathogens for many diseases such as malaria, filariasis, encephalitis, yellow fever and dengue fever in the world. Given that no research has been conducted to determine the fauna of existing mosquitoes in the city of Poldokhtar, Lorestan Province, the present study aimed to exactly determine the mosquitoes' fauna in this city to perform appropriate prevention measures. Methods: In this faunistic and cross-sectional descriptive study, four urban areas and four rural areas in four geographic directions in the city of Poldokhtar were determined. In each urban area, two places and in each designated rural area, four places including two human places and two animal places were selected. From the early of April 2015 to the early of January 2016, larvae, pupae and adult mosquitoes of the Culicidae family were collected. Sampling methods for larvae, pupae and mature were ladling, night catch, total and hand catch with an aspirator. Characteristics including the name of the collector, date of collection, code related to habitat, habitat status (permanent or temporary, type of vegetation cover, type of substrate, and the situation of sunlight were recorded in the related form. The samples were identified by resources and valid identification keys. The data were analyzed using the SPSS software version 19. Results: Totally, 5392 mosquito adults of the Culicidae family including 1818 mosquito adults and 3574 larvae in designated areas in the city as well as four rural areas were collected. The three genera Anopheles (21.9%, Culex (64.6%, and Culiseta (13.5% were diagnosed. Also, from three genera, 12 species were identified as follows: Culex theiler, Cx

    As projected by UN that two-thirds of Indonesia’s population will live in urban areas by 2050, rapid urbanization is happening in Indonesian cities. Initial research on eight Indonesian Cities (which includes Medan, Jatinegara, Bandung, Surakarta, Yogyakarta, Surabaya, Balikpapan, and Manado) by Tunas Nusa Foundation since 2012 shows that urbanization of each city has happened throughout history creating cultural, economic, and environmental networks that are distinct from one city to another. While the networks remain until today and continuously shapes the urban agglomeration pattern, not all parts of the city could undergo subsequent development that confirms the existing pattern, leading to the creation informality. Nor could it make future planning that comprehends the nature of its integrated urban dynamic beyond its current administrative authority. In this paper, we would like to share our study for Medan, North Sumatra as it shows a portrait of a city with a long relationship to a global network since the Maritime trade era. Medan has become home to many ethnic groups which have sailed and migrated as part of a global economic agenda creating a strong economic network between port cities along the Malacca Strait. The city has kept its role in the global economic network until today, to name a few, becoming the frontier for the Indonesia-Malaysia-Thailand Growth Triangle. While we celebrate Medan’s potential to become a global city with major infrastructure development as well as cultural assets as its advantage in the future, we argue that microscale cohesion supported by government policy in agreed planning documents are fundamental for the city to thrive amidst the challenges it is facing. Yet, these cultural assets, as well as micro scale cohesion in Medan City today, are still undermined. Thus, informality in Medan exists as result of ignorance and marginalization of certain socio-cultural groups, abandoning places and identity, as well as the

    the contemporary city and maybe the understanding of the city needs to be updated in some areas, before we are able to do so. In this paper, the focus will be directed towards two themes which become present with the Shrinking Cities phenomenon and therefore seems important to discuss in order to understand...... the concept of Shrinking Cities. These two themes may affect the understanding of the existing city theory. The first theme is concerned with the physical understanding of the city where the traditional assumption about the city as a high density area, with buildings as the dominant structure, is questioned....... Here the concept of the city as an urban landscape will be introduced. The second theme points to the need for a discussion regarding the object of our planning when developing the cities. Previously, the purpose of city development has been growth and expansion, but with the Shrinking Cities...

    A coprological survey including 476 2-18 year old school children from six rural localities between 2627 and 3061 m altitude was performed in Cajamarca province, Peru. Prevalences of fascioliasis ranging from 6.7 to 47.7% (mean 24.4%) proved to be the highest so far recorded in that human hyperendemic area. Higher prevalences in females and in the 2-5 year old group were not significant. Intensities ranged from 24 to 864 eggs per gram (arithmetic mean: 113; geometric mean: 68), the majority shedding less than 100, and without significant differences according to gender or age group. Fasciola hepatica was the most common helminth within a spectrum of 11-12 protozoan and 9-11 helminth species, 97.3% of the children showing infection with at least one parasite. The highest levels corresponded to coinfection with seven different species in females and subjects older than 5 years. Fascioliasis prevalence correlation with altitude appeared significant. An epidemiological characterisation of the valley transmission pattern of fascioliasis in Cajamarca is made by comparison with other better known hyperendemic areas. Results suggest that human fascioliasis may be widespread throughout different parts of Cajamarca province, even far away from the city, and that long-term fascioliasis chronicity and superimposed repetitive infections may be probably frequent.

    Shang Guan, Chang-Yue; Li, Yu; Ma, Hong-Lin

    2017-01-01

    Background: Township cadres, considered as basic executors of state policy, play an important role in Chinese society. Their job satisfaction is a vital issue for township management, but there are few studies on this topic in China. The goal of this study is to analyze the relationship between occupational stress and job satisfaction, and to further examine whether psychological capital (PsyCap) can serve as a mediator between stress and job satisfaction in Chinese township cadres. Methods: A cross-sectional survey was carried out during the period of from October 2015 to January 2016 in Liaoning Province of China. The questionnaires, which consisted of an effort-reward imbalance scale, Minnesota Satisfaction Questionnaire (MSQ) for job satisfaction, and the psychological capital questionnaire (PCQ-24), as well as questions about demographic characteristics, were distributed to 1800 township cadres and complete responses were received from 1525 participants. Structural equation modeling was used to examine the role that psychological capital played in mediating between occupational stress and job satisfaction. Results: In the present study, effort-reward ratio (ERR= 11 × effort/6 × reward) was negatively associated with job satisfaction (r = −0.372, p job satisfaction in township cadres (r = 0.587, p job stress and job satisfaction. Conclusions: Psychological capital partially mediated the relationship between job stress and job satisfaction among Chinese township cadres. Interventions to improve Chinese township cadres’ job satisfaction should be developed in the future, especially the enhancement of PsyCap. Interventions need to be verified in further cohort studies. At present, we are only proposing a theoretical model. Intervention effects need to be validated in further cohort studies. PMID:28846644

  13. The City on Screen: A Methodological Approach on Cinematic City Studies

    Directory of Open Access Journals (Sweden)

    Sertaç Timur Demir

    2015-07-01

    Full Text Available The city has a strong memory and it never forgets its own experiences. The past, the present and the future of the city can be read in its streets, buildings, sounds, myths, rhythms and stories. More importantly, if the city is portrayed through a camera, it becomes as fictional and designable as films. At this stage, there is no difference between watching a film and seeing a city. Also, cinema itself turns into a paradigm that belongs to the city. This parallelism between the city and film is like an inevitable destiny so much so that they constitute and develop each other. Accordingly, those who attempt to understand the notion of the city should consult the films made about them and vice versa; hence, this paper deals with the question of how the city is cinematized, but this question involves another question: how does the cinematic imagination fictionalize itself in the city?

    2013-09-01

    A total of 8 representative surface sediment sampling sites were collected from the Qingshan Reservoir in Lin'an City of Zhejiang Province to investigate the differences in the total concentrations of As, Cr, Cu, Ni, Mn, Pb, and Zn among the sampling sites. The different forms of the heavy metals, i. e., acid soluble, easily reducible, easily oxidizable, and residual, were determined by BCR sequential extraction method, and the pollution degrees and potential ecological risk, of the heavy metals in the surface sediments at different sampling sites of the Reservoir were assessed by using geo-accumulation index (I(geo)) and Hakanson potential ecological risk index. There existed obvious spatial differences in the total concentrations of the heavy metals in the surface sediments of the Reservoir. The sampling sites nearby the estuaries of the tributaries flowing through downtowns and heavy industrial parks to the Reservoir had obviously higher heavy metals concentrations in surface sediments, as compared to the other sampling sites. In the sediments, Mn was mainly in acid extractable form, Cu and Pb were mainly in reducible form, and As was mainly in residual form. The surface sediments at the sampling sites nearby the estuaries of the tributaries flowing through downtowns to the Reservoir had higher proportions of acid extractable and reducibles forms of the heavy metals, which would have definite potential toxic risk to aquatic organisms. Among the 7 heavy metals in the surface sediments, As showed the highest pollution degree, followed by Cu, Ni, Mn, Pb, and Zn, which were at moderate pollution degree, while Cr was at non-pollution degree, with relatively low potential ecological risk. Through the comparison of the sampling sites, it was observed that the surface sediments at the sites nearby the estuaries of Jinxi River and Hengxi River flowing through downtowns and heavy industrial parks to the Reservoir showed obviously higher heavy metals pollution degree and

    Surveys were performed in the main Xianlajiao chili pepper-producing areas of Shaanxi Province to determine whether a phytoplasma was associated with the incidence of Arbuscular Lobular Disease (ALD). During July 2012 and 2013, 92 and 86 chili pepper plants, respectively, showing ALD-like symptoms were collected from 12 counties and the cities of Baoji, Weinan, Xianyang, and Xian. Samples from paulownia trees and plantain with symptoms of paulownia witches' broom and little leaf, respectively, located in pepper fields in Baoji city, Fengxiang county were also collected. Universal DNA primers for amplification of the phytoplasma 16S rRNA gene were used for nested PCR assays and DNA sequencing. Phytoplasma DNA was amplified from two chili pepper plants, the paulownia trees, and the plantain collected from Baoji city. The phylogenetic analysis of 16S rDNA sequences of the phytoplasmas detected in the chili pepper confirmed that these phytoplasmas are members of the 16SrI group "Candidatus Phytoplasma asteris". The results of virtual RFLP analysis and sequence homology comparison showed that the two Xianlajiao phytoplasmas have high homology with phytoplasmas 16SrI-B and 16SrI-M. Transmission electron microscopy assays revealed the presence of typical phytoplasma pleomorphic bodies in the phloem of phytoplasma-infected Xianlajiao chili pepper plants. Although our results did not establish a strong association between the presence of the phytoplasma and ALD, the simultaneous detection of a 16SrI phytoplasma in two symptomatic Xianlajiao chili peppers, the paulownia trees, and the plantain suggests a complex epidemiology related to the 16SrI phytoplasma pathogen in these new plant hosts.

    2017-11-01

    Full Text Available This article describes the daunting challenge of precarious housing in Salvokop located in the southern part of inner City of Tshwane, Gauteng Province. Insecure tenure, unmaintained dwellings, overcrowding, mushrooming of backyard shacks and the rise of the informal settlement, all that led to deep levels of vulnerability and neighbourhood deterioration. Current conditions show that life in that neighbourhood is fraught as substandard housing degenerated into slum and squalor. This concern emerged among other salient pressing issues of poverty and vulnerability from the World Café and Focus Groups with the inner city churches including those from Salvokop. The article set out to describe precarious housing, unpleasant living conditions owing to the fact that human beings stay in unsuitable dwellings while the environment deteriorates. Taking into account their circumstances, the article’s aim was to recapture the extent to which the residents suffer as a result of living in dwellings unfit for human habitation, rethinking an alternative model to respond. A theological agenda for future ecclesiological engagement was discerned forthwith recommendations. The article makes a contribution towards the theology of the city in that it stimulates church practices and housing of poor people in Tshwane. It does so by engaging in a unique way grassroots knowledge from the different inner city congregations. This process used the platform of surveys, World Café style gatherings and Focus Groups. In conversation with the primary source, this article also contributed with original data generated with the Salvokop residents whose stories helped to expend on horizons of housing, which is acknowledged. All the inner city church contributors of the realisation of the study objectives are also recognised.
