    A survey was carried in North Khorasan Province, Iran in 2010-2011, designed to identify Theileria spp. infections of both sheep and ticks. The tick species were also examined. Ninety sheep from different flocks were clinically examined, and blood samples and ixodid ticks were collected. Light microscopy of blood smears revealed Theileria spp. infection in 37 (41.1 %), while 74 (82.2 %) of blood samples were positive using semi-nested PCR. Theileria ovis, Theileria lestoquardi, and mixed infection were detected in 63/90 (70 %), 5/90 (5.5 %), and 6/90 (6.6 %) of samples, respectively. Of the 434 ticks that were collected, the most prevalent species was Rhipicephalus turanicus (69.3 %) followed by Hyalomma marginatum turanicum (18.4 %), Dermacentor marginatus (6.4 %), and Rhipicephalus bursa (5.7 %). The ticks were separated into 42 tick pools, and the salivary glands were dissected out in 0.85 % (w/v) saline under a stereomicroscope and examined using semi-nested PCR. Three pools of H. marginatum turanicum salivary glands were infected with T. ovis and T. lestoquardi, and one pool of R. turanicus was infected with T. ovis. Based on these results, it is concluded that the prevalence of T. ovis is higher than T. lestoquardi and that H. marginatum turanicum and R. turanicus are likely vectors of T. lestoquardi and T. ovis in this area.

    Full Text Available Roudgaz prospect area is a Cu, Sn, Pb, Zn, and Au polymetal vein system located to the southeast of Gonabad and in the northeast of Lut block. Oxidan subvolcanic Tertiary rocks with monzonite to monzodiorite porphyry composition intruded the metamorphic rocks of middle Jurassic. The majority of intrusive bodies are affected by carbonation, argillic, sericitic, and silicification-tourmaline alteration. Mineralization in the area is controlled by fault and is present as vein with domination of NW-SE direction and 85-90º dip. Primary minerals are quartz, tourmaline, chalcopyrite, pyrite, and secondary minerals are malachite, azurite, and goethite. Geochemical sampling using chip composite method indicated high anomalies of Cu, Sn, Pb, and As (up to 10000 ppm, Zn (up to 5527 ppm, and Au (up to 325 ppb. Broad gossan zone is present in the area and is related to the oxidation of sulfide minerals. IP/RS survey was performed over the geochemical anomalies for identification of the location and extension of sulfide mineralization at depth. Generally, chargeability increases in gossan zones, veins, old workings and geochemical anomalies. Resistivity over the quartzite unit and also in locations where mineralized vein is associated with quartz has a high anomaly of up to 425 ohm-m. Due to high geochemical anomaly of Sn and its relation with reduced subvolcanic intrusives, ground magnetic survey was performed to identify the location of magnetite (oxidant and ilmenite (reduced series at depth. Variation of Total Magnetic Intensity (TMI is 335.1 Gamma in the TMI map. The highest magnetic anomalies in the RTP map are located to the north of the survey area which is related to magnetite series (hornblende biotite monzodiorite porphyry and extend to the south at depth. The lowest magnetic anomaly is located to the center of the survey area and particularly to the east of the Roudgaz village correlating the highest chargeability and geochemical anomaly. Based

    The objective of this study was to develop a thermal model that can be used for prediction of saffron flowering time. For this purpose, existing data on saffron flower emergence time were collected in a wide range of temperature regimes over the saffron production regions of Khorasan province, Iran. Linear second-order polynomial and 5-parameter beta models were used and statistically compared for their ability in predicting saffron flowering time as a function of temperature. The results showed a significant delay in flowering date across the temperature gradient. While beta model had a better statistical performance but the simple linear model also showed a good predicting ability and therefore, can be used as a reliable model.

    Toxoplasmosis is an important zoonotic disease with worldwide distribution. The infection is observed in an unusually wide range of warm-blooded animals, including most of the livestock and humans. Many studies have shown high prevalence of toxoplasmosis in man and animals in Iran. The present study was conducted to investigate the seroprevalence of toxoplasmosis in Turkoman horses in the North Khorasan Province. During 2011-2012, 100 blood samples from horses were collected and tested for antibodies against toxoplasmosis using indirect fluorescent antibody test. The seroprevalence of toxoplasmosis was detected in 14 % (14) horses. The antibodies titres were detected in the range of 1:20-1:160 dilution. The lowest and highest frequencies of toxoplasmosis were observed in the age groups of toxoplasmosis frequencies and gender and usage of horses. With regard to the high frequency of toxoplasmosis in the sampled horses, attention must be paid to the animal health for the control and prophylaxis of the disease. PMID:27413330

    The causes and situation of exudative pleural effusion vary from one area to another. A cross-sectional study was conducted on 327 patients with exudative pleural effusion in South Khorasan province (Iran). The patients were older than 12 years and comprised 172 (52.6%) males and 155 (47.4%) females. The study commenced in 2007 with seven years duration. The Light’s criteria were used to define exudative effusion. Procedures including pleural fluid analysis, microbiological study, pleural biopsy, and systemic investigations were conducted to determine the special cause of pleural effusion. The mean age of the patients was 63.4±18.4 years. Malignancies, tuberculosis, and parapneumonia pleural exudation were diagnosed in 125 (38.2%), 48 (14.7%), and 45 (13.8%) cases, respectively. Among malignant effusions, metastasis from lung cancer made 48 (38.4%) of the cases. The origin of metastasis was not determined in 44 (35.2%) patients. The mean age of patients was not significantly different between malignant (66.9±14.3 years) and tuberculosis (63.9±19.7 years) cases (P=0.16). The older age of tuberculosis patients could be a new discussion point on the overall impression created on the subject of tuberculosis pleural exudation (TB-PLE) occurring in young people.

    Full Text Available Extended abstract1-IntroductionToday, one of the essential issues facing managers and planners is allocating resources to the spots which have the potentials to reserve the capital and provide the society with social and economic interests. In addition, finding a suitable spot has been the main concern of managers and planners, i.e. managers and planners, because of the resource deficiency, prefer to allocate the resources to the best places. In this regard, planners since a long time ago have tried to find out methods of choosing the best spot to centralize the industries and activities. Finding a scientific location finding method has always been a main concern of the planners. In this regard, selecting effective criteria in choosing the best spot and using suitable models to modulate data are considered as significant. In the paper, using modern methods of spotting (Hierarchical Analysis and taking economic, social aspects into account, some spots to establish markets for handicrafts in South Khorasan Province were suggested.2- Theoretical basesSimultaneously with the development of industry and its social and economic aftermaths, spotting theories to increase productivity of industrial activities and decrease their negative results and economic losses were offered. The theories have been proposed by thinkers such as: August Losch, A. Weber, Walter Isard, Greenhut, Smith, Palander, Lanhard, Christaler and Micheal Rawstron.Affected by the systemic approaches to the late 1970s issues, spotting theories had a try at concurrent modulation of two previous theories. In this approach activities and industries must be located in a way that it generates the difference between costs and incomes (profit as large as possible for the economic managers.The AHP method, as one of the most modern methods of spotting industry, made the proposed statement so easy by changing attitude, not very unexpectedly, so that it can be certainly used as the most efficient

Because it is likely that stored sesame seeds are contaminated with mycotoxins, the levels of aflatoxins (AF) in five lots of imported sesame seeds before their distribution to the market were studied during one year. A total of 269 sub-samples were obtained from a total of 9,321 tons of sesame seeds from five importing companies. Aflatoxins at >1 μg/kg were found in 50 % of all samples, but at low levels in most cases, which is illustrated by mean AFB1 and total AF levels of 1.25 ± 3.70 and 1.43 ± 4.38 μg/kg, respectively. A few (1.9 %) samples exceeded the National Iranian Standard maximum accepted level for AFB1 (5 μg/kg) or total AF (15 μg/kg); the maximum total AF level found in one sample was 48 μg/kg. The results indicate that the risk of a violative AF contamination in imported sesame seeds is not negligible but is currently relatively low.

Internal organs were examined for any parasites. Helminthes were identified based on morphological characteristics. Smears prepared from peripheral blood as well as liver, spleen and any skin lesion were stained by Giemsa and examined microscopically. Samples obtained from spleen were aseptically cultured in three culture media including NNN, Schneider’s Drosophila (HIMEDIA and RPMI1640 (GIBCO for isolation of Leishmania spp. The titer of anti-Leishmania and anti-Toxoplasma antibodies were measured by direct agglutination test (DAT and indirect fluorescent antibody test (IFAT, respectively.Results: 84% of dogs were infected at least with one species of intestinal helminthes. The species of parasites and rate of infection were as follows: Taenia hydatigena (61%, Dipylidium caninum (46%, Mesocestoides lineatus (19%, Echinococcus granulosus (10%, Toxascaris leonina (53% and Toxocara canis (7%. Anti-Leishmania antibodies were detected by DAT in 8 dogs (8% at 1:320 titers and higher. Forty seven dogs (47% showed anti-Toxoplasma titer at 1:10 and 17 (17% showed titer of ≥1:100. No blood parasites were found in prepared blood smears.Conclusion: The high rate of parasitic infection and presence of zoonotic species

    Full Text Available The closed nature of geochemical data has been proven in many studies. Compositional data have special properties that mean that standard statistical methods cannot be used to analyse them. These data imply a particular geometry called Aitchison geometry in the simplex space. For analysis, the dataset must first be opened by the various transformations provided. One of the most popular of the applied transformations is the log-ratio transform. The main purpose of this research is to identify the anomalous area in the Khusf 1:100000 sheet which is located in the western part of Birjand, South Khorasan province. To achieve the goal, a dataset of 652 stream sediments geochemically analysed for 20 elements was collected. In practice, the geochemical data were first opened by CLR transformation and then the range correlation coefficient (RCC ratio was calculated and mapped. In consequence, the robust factor analysis for compositional data was used to separate the elements, mostly in the high-value regions obtained by the method of RCC. Finally, the priority of anomalies was specified using weighted catchment analysis. The above procedures led to the recognition of some anomaly zones for elements of Cu, Bi, Sb, Ni and Cr in the study area. Such results can be useful for designing an appropriate exploratory plan for semi-detailed and detailed exploration steps.

    Full Text Available Introduction Hornblende-bearing gabbroic rocks are quite common in subduction-related magmatic suites and considered to represent magmatic differentiation process in arc magmas (Heliker, 1995; Hickey-Vargas et al., 1995; Mandal and Ray, 2012. The presence of hornblende as an important mineral phase in gabbroic rocks of subduction zone has been considered either as an early crystallizing mineral from water-bearing mafic magmas (Beard and Borgia 1989; Mandal and Ray, 2012 or as a product of reaction of early crystallized minerals (olivine, pyroxene and plagioclase and water-rich evolved melt/aqueous fluid (Costa et al., 2002; Mandal and Ray, 2012. The careful study of petrology and geochemistry of hornblende-bearing gabbroic rocks from Chahak area, of Neoproterozoic age, can provide important information about their petrogenesis. Because of the special characteristics of Chahak hornblende gabbros according to their age and their situation in the main structural units of Iran, their study can present critical keys for the knowledge of geological history of Iran specially central Iran zone. Material and Methods This study carried out in two parts including field and laboratory works. Sampling and structural studies were carried out during field work. Geological map for the study area was also prepared. 65 thin and polished thin sections for petrographical purpose were studied. Major oxides, rare earth elements and trace elements were analyzed for 4 samples (92P-1, 92P-3, B1and B6 from hornblende gabbros on the basis of 4AB1 method using ICP-MS of ACME Laboratory from Canada. In addition, major oxides of three hornblende gabbro samples (89P-62, 89P-59 and 89P-46 were used from Partovifar (Partovifar, 2012. Results and discussion Fariman metamorphic terrains, of Proterozoic age, consist of metamorphosed sedimentary and igneous (plutonic and volcanic rocks. Hornblende gabbros of the study area include plagioclase, hornblende, biotite pyroxene and

    Full Text Available Introduction Pyrite is the most abundant sulfide mineral in low sulfidation ore deposits. Experimental studies have shown that low-temperature ( 200°C from hydrothermal or metamorphic fluids (Butler and Rickard, 2000. Framboidal pyrite mostly occurs in sedimentary environments, though it could also form during metamorphism and hydrothermal alteration (Scott et al., 2009. The pyrite formed tends to be enriched in various trace elements such as Au and As. For this study we have combined the geology, alteration, mineralization with recent studies of the description of the deposit from core logging and underground mapping and geochemistry in the CheshmehZard gold district and also investigated the compositional variation and textural differences between pyrite types. This study is based on the results of our alteration and mineralization mapping and detailed logging of 1937.8 m of drill core. Materials and Methods Geology, hydrothermal alteration and mineralization were examined in drill holes along several cross sections. Host-rock alteration minerals and veins were determined for 11 samples using standard X-ray diffraction (XRD and X-ray fluorescence spectrometry (XRF techniques. Polished sections were studied by reflected light microscopy and backscattered electron images (BSE. In this study, the trace-element composition of pyrite samples from the Au-III vein system was obtained using electron microprobe analyzer (EMPA data. All analyseswere carried out at the department of Materials Engineering and Physics of the University of Salzburg in Austria. The EMPA measurements and BSE imaging were made using a JXA-8600 electron microprobe. Spot analyses of 30 pyrite grains from CheshmehZard are given in Table 1. Results The study area is located in the north of Khorasan Razavi Province 45 km to the south of Neyshabour. The area near CheshmehZard could become important as a site of economically significant gold mineralization. Six gold-bearing vein

The percentage change in CSR in 2010 compared to 2006 was conducted in each province, retrospectively. One hundred and ten centers were chosen from all provinces, to determine CSR in each, the weight of major (>3,000 annual surgeries and minor (3,000 annual surgeries or less centers was calculated based on the number of selected centers, and multiplied by the number of surgeries in each province.In eight provinces, CSR was decreased by 1-60%. One province (Booshehr showed no change. Eighteen provinces had 2-79% increase. No 2006 data was available in three provinces. North Khorasan had the most decrease while Kerman had the most increase in CSR. Six of these 8 provinces had CSR>3,000 despite a decrease in 2010, but North Khorasan had CSR<3,000 over the whole 5 year period. In 4 provinces, CSR had a gap from 3,000 despite an ascending trend, and in two, the gap was quite considerable.Although CSR has an improving trend in most provinces in Iran, it is decreasing in some provinces, and despite an already low CSR, the exacerbation continues. The growing population of over 50 year olds calls for prompt measures in such provinces. Even in improving provinces, some lag behind the minimum recommended by WHO, and the growth rate of the over 50 population reveals the necessity of immediate planning.

    Jilin Province is one of the main grain-producing provinces of China, which has dominant position in maize production, by the view of its advantages in policy, location, breed and market. And after entering WTO,some measures have been taken to enhance maize competitive ability. But there are some difficulties in concentrating production to maize advantaged areas. This paper expounds the basis that Jilin Province becomes the advantage area of maize, analyzes the problems and puts forward the supporting policy. Some strategic measures are proposed,as developing comparable advantages, carrying out the strategy of un-equilibrium development and cultivating advantaged product areas of maize to rapidly improve the international competitive ability and productivity of maize in Jilin Province, cast the agricultural predicament off and promote the agricultural development into a new stage.

    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. PMID:15641386

    According to the age of major reservoirs, hydrocarbon occurrences in Libya and adjacent areas can be grouped into six major systems which, according to their geographic locations, can be classified into two major hydrocarbon provinces: (1) Sirte-Pelagian basins province, with major reservoirs ranging from middle-late Mesozoic to early Tertiary, and (2) Murzog-Ghadames basins province, with major reservoirs ranging from early Paleozoic to early Mesozoic. In the Sirte-Pelagian basins province, hydrocarbons have been trapped in structural highs or in stratigraphic wedge-out against structural highs and in carbonate buildups. Here, hydrocarbon generation is characterized by the combined effect of abundant structural relief and reservoir development in the same hydrocarbon systems of the same age, providing an excellent example of hydrocarbon traps in sedimentary basins that have undergone extensive tensional fracturing in a shallow marine environment. In the Murzog-Ghadames basins province, hydrocarbons have been trapped mainly in structural highs controlled by paleostructural trends as basement arches which acted as focal points for oil migration and accumulation.

Among Iranian species, five are found in the Razavi, North and South Khorasan provinces. Eighty morphological characters were measured in 44 herbarium specimens belonging to: H. calycinus, H. bituminosus, H. platystegius and H. elegans. The Kruskal-Wallis Test was implemented to evaluate which characters significantly differentiate the species. Thus, forty-two morphological characters were used in subsequent analyses. Taxonomic relationships were investigated using the Principal Component Analysis (PCA. H. bituminosus and H. platystegius were separated in two distinct groups. There was no sharp distinction between the two other species, H. calycinus and H. elegans. Canonical discriminant analysis (CDA was also applied to find the best discriminating traits among the species.

    Full Text Available This study aimed to estimate methane emissions from the mangrove area of Ranong Province andto explore the factors affecting the emissions, as part of an attempt to evaluate methane contribution to the global methane budget. Methane was measured by using a closed chamber technique and analyzed by a gas chromatograph equipped with a flame ionization detector (FID. The results showed that the annual estimated methane emission was released at approximately 157.32 mg/m2. The amount of methane emission from this mangrove area was lower than in other previously studied areas. Emission rates varied seasonally with the highest rate in the rainy season followed by summer and cold seasons, during which the values were 0.52, 0.27, and 0.19 mg/m2/day, respectively. Seasonal variations of methane emission was related to several factors depending upon field conditions such as water conductivity, soil temperature, and water level.

    The Eastern Coal Province is divided into 24 hydrologic reporting areas. This report describes the hydrology of area 18 which is located in the Cumberland River basin in central Tennessee near the southern end of the Province. Hydrologic information and sources are presented as text, tables, maps, and other illustrations designed to be useful to mine owners, operators, and consulting engineers in implementing permit applications that comply with the environmental requirements of the ' Surface Mining Control and Reclamation Act of 1977. ' Area 18 encompasses parts of three physiographic regions; from east to west the Cumberland Plateau, Highland Rim, and Central Basin. The Plateau is underlain by sandstones and shales, with thin interbedded coal beds, of Pennsylvanian age. The Highland Rim and Central Basin are underlain by limestone and dolomite of Mississippian age. Field and laboratory analyses of chemical and physical water-quality parameters of streamflow samples show no widespread water quality problems. Some streams, however, in the heavily mined areas have concentrations of sulfate, iron, manganese, and sediment above natural levels, and pH values below natural levels. Mine seepage and direct mine drainage were not sampled. Ground water occurs in and moves through fractures in the sandstones and shales and solution openings in the limestones and dolomites. Depth to water is variable, ranging from about 5 to 70 feet below land-surface in the limestones and dolomites, and 15 to 40 feet in the coal-bearing rocks. The quality of ground water is generally good. Locally, in coal-bearing rocks, acidic water and high concentrations of manganese, chloride, and iron have been detected. (USGS)

    Bueno Ramírez, Primitiva

    2002-12-01

    Full Text Available This paper offers a reflection on the social, cultural and chronological implications of the funeral world of the inland Tagus basin. In particular the data of the province of Toledo, analysed from the site of the megaliths of Azutan and the burial mound of the Castillejo, allows us to propose the contemporaneity of several architectural types in the early Megalithic culture of Iberia and the association between habitats and graves. The economic niches, mainly cultivated meadows with areas for sowing grain and pasture for animals, suggest the existence of a mixed economy in a peasant society practised by groups who returned to the same places from the earliest moments of the Neolithic to the Bronze Age.

    Se plantea una reflexión sobre las implicaciones sociales, culturales y cronológicas del mundo funerario al interior del Tajo. Concretamente los datos de la provincia de Toledo; analizados desde los yacimientos del dolmen de Azután y del túmulo del Castillejo, plantean la contemporaneidad de distintas versiones arquitectónicas en el megalitismo antiguo peninsular y la asociación manifiesta entre hábitats y sepulturas. Los nichos económicos, fundamentalmente dehesas cultivadas con zonas aclaradas para la siembra de cereal y para los pastos de los animales, abogan por proponer una economía mixta en un modelo de explotación campesina protagonizado por grupos que acuden de modo recurrente a los mismos lugares desde los momentos más antiguos del Neolítico hasta la Edad del Bronce.

    Full Text Available This paper aims to describe the adolescent fertility in Cuba during the period 2010-2014 and analyze its proximate determinants both nationally and by territory. Based on the data published in Demographic Yearbook, Studies and Data of the Population and birth databases of the National Bureau of Statistics and Information (ONEI, adolescent fertility rates in Cuba are calculated according to the groups 10-14 and 15-19, by province and area of residence. In addition, data on family formation, contraception and abortion of Cuban adolescents are shown. These elements could allow hypothesizing about the behavior of adolescent fertility in Cuba. The first important result is that fertility among 15-19 years group had a slight decrease in the period; however, the 10-14 years group has increased its level. On the other hand, the analysis by area of residence shows that urban fertility has gained prominence in the Cuban provinces, with an increase between 2010 and 2012 in more than half of them. Similarly, about a third of the provinces analyzed show higher levels of adolescent fertility in urban areas than in rural areas. High rates of abortion in adolescence, which exceeds fertility rates in ten provinces of the country; early onset of sexual intercourse and first marriage, and improper use of contraceptive methods, are elements worth looking into in order to find explanations to the reproductive behavior of Cuban adolescents.

    Full Text Available A scientific definition of the type of mountain area and an exploration of the spatial correlation between different types of mountain areas and regional land use at the county level are important for reasonable land resource utilization and regional sustainable development. Here, a geographic information system was used to analyze digital elevation model data and to define the extent of mountainous land and types of mountain areas in Guizhou province. Exploratory spatial data analysis was used to study the spatial coupling relation between the type of mountain area and land use degree in Guizhou province at the county level. The results were as follows: (1 Guizhou province has a high proportion of mountainous land, with a ratio of mountainous land to non-mountainous land of 88:11. The county-level administrative units in Guizhou province were exclusively mountainous, consisting of eight semi mountainous counties, nine quasi mountainous counties, 35 apparently mountainous counties, 13 type I completely mountainous counties, and 23 type II completely mountainous counties; (2 The land use degree at the county level in Guizhou province have remarkable spatial differentiation characteristics. Counties with a high cultivation coefficient are mainly located in the western area along the line between Yinjiang county and Anlong county in west Guizhou province. Counties with a large proportion of construction land or a high integrated index of land use degree are mainly distributed in the economically developed area of central Guizhou province, including parts of the counties (districts/cities administrated by Guiyang, Zunyi, Liupanshui, Anshun, Duyun, and Kaili; (3 County-level administrative units with relatively flat topography and a low proportion of mountainous land have a large proportion of construction land and a large degree of regional land exploitation. However, the extent of cultivation of county-level administrative units under similar

    Full Text Available DOI: 10.17014/ijog.v7i4.148Geological features in Labuhan area were studied from the middle of October to the middle of November 2011 covering seventy days. Surface and subsurface data were obtained from interpretation of landsat images and shallow hand-auger boreholes. The geological features are distinctly associated with active tectonics. The stratigraphy clearly indicates at least three phases of tectonic activities since the Late Miocene until Holocene. Tectonics of phase one occurred in the Late Miocene; phase two took place in the period from Pliocene to Late Pleistocene, while tectonics phase three is ongoing in the Holocene. Volcanic activity has intensified since the Early Pleistocene. The landsat images show an irregular outline of the northern coast line. This penomenon is interpreted to be the result of tectonic uplift. On the other hand, the southern coast is linear in plan which is interpreted to correlate with tectonic subsidence. Furthermore, stratigraphic correlation shows that depositional environment changed vertically due to a local subsidence. The northern researched area is occupied by Pleistocene volcanic eruption centres, whilst the younger ones tend to shift southward. This fact tends to indicate that the subduction zone moved southward slowly.

The selected area is located to the East of Coloradas, Department Catan Lil in the Province of Neuquén comprising a surface of 9000 ha, part of it being privately owned, and the rest being the government land occupied by livestock breeders. The selected area is justified by the fact that it is one of the poorest and most fragile areas of the province considering its ecosystem potentialities, different forms of property possession -government or private land- and the aborigine communities. In this particular case study, private land and that occupied by livestock breeders is considered. From the analysis, it appears that the dynamics and the landscape respond to forms of management according to the type of land possession.

    Full Text Available Khorasan wheat occupies a special place in the group of new-old cereals (Triticum turgidum, ssp. Turanicum McKey. It is an ancient species, native to eastern Persia, that is very close to durum wheat by morphological characteristics. Investigations were carried out in agro ecological conditions of the eastern Srem, with two wheat populations with dark and bright awns as objects of study. The following morphological and productive characteristics were investigated: plant height (PH, spike length (SH, number of spikelets per spike (NSS, absolute weight (AW and grain weight per spike (GW, seed germination (G and grains yield (YG. Field micro-experiments were set on the carbonate chernozem soil type on loess plateau in 2011 and 2012. Hand wheat sowing was conducted in early March with drill row spacing of 12 cm. The experiment was established as complete randomized block system with four replications. Tending crops measures were not applied during the growing season. Plants were grown without usage of NPK mineral nutrients. Chemical crop protection measures were not applied, although powdery mildew (Erysiphe graminis was appeared before plants spike formation in a small extent. The results showed that both populations have a genetic yield potential. In general, both populations manifested a satisfactory tolerance on lodging and there was no seed dispersal. Plants from bright awns population were higher, had longer spikes and larger number of spikelet’s per spike. However, plants from dark awns population had higher absolute weight and grains weight per spike, as well as grain yield per plant. Strong correlation connections were identified among the investigated characteristics. The determination of correlations, as well as direct and indirect affects, enabled easier understanding of the mutual relationships and their balancing in order to improve the yield per unit area.

    Full Text Available Background: Several studies have investigated the prevalence and awareness of diabetes mellitus (DM in China, but little is known about the situation of DM in the northeastern rural areas. Our present study investigated the prevalence, awareness and associated characteristics of DM in rural areas of Jilin Province, aiming to suggest more efforts for the prevention and control of DM. Methods: A multistage stratified random cluster sampling design was used in this cross-sectional study which took place in 2012. Data were collected by face-to-face interviews and physical examinations. Rao-Scott Chi-square test, t test and multivariate logistic regression analysis were used. Results: The estimated prevalence of DM in rural areas of Jilin province was 7.2%. DM was positively associated with age, Body mass index (BMI, hypotension, dyslipidemia and was high in participants with a family history of diabetes and those who exercise frequently, but low for high education level and married participants. 69.0% participants with DM were aware of their diabetes status, 88.2% of whom received treatment and 34.4% of whom had received treatment controlled their DM status. Conclusions: We observed a high prevalence and low awareness status of DM among the rural residents in Jilin Province, but the rate of effective control in those who have received treatment was considerable. The low rate of disease surveillance should draw health authority’s attention.

    This paper investigated the genus diversity of soil nematodes of different agricultural areas in Jiangsu Province, analyzed the relationship between soil nematodes and soil environmental factors, and discussed the roles of soil nematodes as biological indicators of soil health. The results showed that, a total of 41 nematode genera were found in all six agricultural areas, belonging to 19 families, 7 orders, 2 classes. The numbers and community compositions of nematodes were obviously influenced by soil texture, fertilization and tillage practices. In all six agricultural areas, the numbers of nematodes in coastal agricultural area (400 individuals per 100 g dry soil) were significantly larger than that in Xuhuai, Ningzhenyang, and riverside agricultural areas. While the smallest number of nematodes was found in Yanjiang agricultural area (232 individuals per 100 g dry soil), which might be due to the differences in soil texture, annual rainfall and annual air temperature and other factors. The dominant genera of nematodes were similar in the adjacent agricultural areas. Correlation analysis showed that there was a significant positive correlation between the number of soil nematodes and levels of soil nutrients (soil organic matter, total nitrogen, available nitrogen, available potassium and available phosphorus). Redundancy analysis (RDA) indicated the total nitrogen, available potassium and pH obviously affected some soil nematode genera. The analysis of spatial distribution characteristics of soil nematode community in farmland of Jiangsu Province could provide data for health assessment of agricultural ecosystems. PMID:26915207

    Full Text Available Alveolar echinococcosis (AE is a lethal parasitic disease. In Gansu Province of China, all AE cases reported in literature were from Zhang and Min Counties, the southern part of the province. Here, we report the discovery of nine AE cases and one cystic echinococcosis (CE case from Nanfeng Town of Minle County, in the middle of Hexi Corridor in west Gansu Province. The diagnosis of these cases were confirmed by serology, histopathology, computed tomography, B-ultrasound, immunohistochemistry method, DNA polymerase chain reaction and sequencing analysis. Because eight of nine AE cases came from First Zhanglianzhuang (FZLZ village, we conducted preliminary epidemiological analyses of 730 persons on domestic water, community and ecology such as 356 dogs' faeces of FZLZ, in comparison with those of other five villages surrounding FZLZ. Our studies indicate that Nanfeng Town of Minle County is a newly discovered focus of AE in China as a CE and AE co-epidemic area. Further research of Echinococcus multilocularis transmission pattern in the area should be carried for prevention of this parasitic disease.

    The seroepidemiological condition of malaria in three main districts of Hormozgan Province, a low transmission area in southeast of Iran, was investigated. Methods. Sera samples (803) were collected from healthy volunteers from the three main districts (Bandar Lengeh in the west, Bandar Abbas in the center, and Bandar Jask in the east) of Hormozgan Province. A questionnaire was used to record the sociodemographic features of the participants during sample collecting. An in-house ELISA test, using crude antigens obtained from cell culture of Plasmodium falciparum, was adapted and used to detect anti-malaria antibodies in the sera. Results. The overall seroprevalence of malaria was 8.7% (70 out of 803 samples). A significant correlation was found between seropositivity and place of residence, where the highest rate of seropositivity was seen in Bandar Lengeh (west of the province). The highest seroprevalence of malaria (13.2%) was seen in the age group of 11–20 years and also in low educated individuals. Correlation between seropositivity and gender, age, and educational levels of the participants was statistically significant (P < 0.05). Conclusion. Findings of this study indicate that the rate of seropositivity to malaria in this area is not high and this might be linked to the success of malaria control programs during the last decades in the region.

    This paper deals with the chemical and isotopic compositions of escaped gases from the Rehai geothermal area in Tengchong county of Yunnan Province. Results indicate that there is the mantle-derived magmatic intrusion in shallow crust at this area. Modern mantle-derived mag-matic volatiles are being released currently in a steady stream by way of active faults. The escaped gases are mostly composed of CO2, together with subordinate amounts of H2S, N2, H2, CH4, SO2, CO and He. At the studied area, the north-south directed fault is the deepest, and it may be interlinked with the deep-seated thermal reservoir that would be directly recharged by the mantle-derived magmatic volatile. The He, C isotopic evidence reveals that the modern active magma beneath Rehai area may originate from the historical mantle-derived magma which caused the latest eruptive activity of volcanoes in that region.

    Full Text Available Agroforestry areas have a significant and recognized productive, socio – economic, environmental and landscape role. An important ecological function performed by these areas is the net absorption of considerable quantities of atmospheric carbon dioxide. The scientific knowledge of the CO2 assimilation capacity of agroforestry ecosystems in a territory, is a useful and innovative means to support territorial planning. In the interests of environmental sustainability, emissions from human activities carried out in a specific local context, must be adapted by the simultaneous capacity of CO2 sequestration. For the protection of environmental quality, the choice of land use should therefore optimize the circuit of interaction between emissions and absorption. This work takes into account the agroforestry areas of the Province of Bari to estimate the potential capacity to absorb CO2 and compare it, with the current emission levels.

    Full Text Available This study on the natural and degraded natural vegetation of natural areas in the Potchefstroom Municipal Area, forms part of a research programme on spontaneous vegetation in urban open spaces in the North West Province, South Africa. Using a numerical classification technique (TWINSPAN as a first approximation, the classification was refined by applying Braun-Blanquet procedures. The result is a phytosociological table from which 6 plant communities were recognised, which are subdivided in sub-communities and variants, resulting in 18 vegetation units. Some of these vegetation units are similar to communities described previously in natural areas. The presence of degraded natural communities suggests huge anthropogenic influences in certain areas. An ordination (DECORANA scatter diagram shows the distribution of the plant communities along gradients which could be related to vegetation structure, altitude, soil depth, rockiness of soil surface, wetness or dryness of the habitat and number of introduced species. This study contributes to the compilation of a guideline for a conservation orientated management plan for the area, but also created a wealth of new knowledge of the reaction of indigenous plant species under disturbed conditions.

    Damaging earthquakes on faults typically recur at intervals of centuries to millennia but the seismographs that record them have only been around for about hundred years. Complete records of earthquakes of Ms5 or above for Anhui Province of China and its adjacent areas began in 1336 and most previous records were lost. To reduce the hazard from earthquakes we need a longer record of them than can be provided from such instruments. Archaeoseismological evidence has the potential to determine earthquake activity over millennial time spans, especially when integrated with historical documents and geological evidence. In recent years, taking advantage of large-scale civil excavations, our research team including earthquake and archaeological scientists have cataloged, identified, and analyzed deformation relics of the late-Quaternary period, especially the Neolithic Age. Prehistoric earthquake traces were found in the cultural layers of the Western Zhou Dynasty and the Spring and Autumn Period in Southwest Anhui, the late Dawenkou cultural period in North Anhui, and the Eastern Zhou in South Henan. Along the segment of the Tanlu Fault Zone on the border of Jiangsu-Anhui Provinces, several rapid deformation events mainly in the form of oblique translational thrust had occurred since Late Pleistocene, which was confirmed by microscopic studies. The research findings have partly filled the gap of earthquake records in the area and enriched research methodologies in archaeology, prehistoric earthquakes and earthquake prediction. The project was sponsored by China Earthquake Science Special Research Funding Program (#201308012)

The results showed that pollution of PM2.5 was serious and the concentration levels of S, Zn, Pb and As were similar to city. There are different seasonal distribution laws of pollutant elements in PM2.5 between two sampling sites, probably due to contribution of local sources, medium or long distance transportation of fine particulates and complicated meteorological conditions. The enrichment levels of S, Zn, Pb, As, K were high,reflecting the influence of anthropogenic activities. Particularly enrichment level of S was much higher in summer, which was probably related to meteorological condition. The result of principal components analysis showed major sources of PM2.5 included crustal resuspension, coal burning, metal processing industry or waste incineration, vehicular emission, which suggests anthropogenic activities is of important influence on PM2.5 in rural areas of southem Jiangsu Province.

  20. Charnockite Formation and Early Precambrian Crust Evolution in Yishui Area, Shandong Province, China

    Charnockite and granulite in Yishui area, Shandong Province are located in the middle part of the Tancheng-Lujiang fault zone, eastern China. Field studies have shown that the charnockites, derived from the adjacent granulites, are classified as three types: enderbite, garnet-enderbite and hypersthene-trondhjemite. In addition, two generations of minerals are present in the charnockites: the relic minerals such as garnet, hypersthene and clinopyroxene, and the neocrystallized minerals such as plagioclase and K-feldspar. The relic minerals occurring in the granulite facies stage were affected by the later partial melting. The relic minerals, irregular and usually ragged in shape, occupy the interstitial positions in the neocrystalline minerals. The neocrystalline minerals are usually euhedral-subhedral crystals. The study of petrology, mineralogy and geochemistry of charnokites concludes that the enderbite was formed by the anatexis of the two-pyroxene plagioclase granulite, that the garnet-enderbite was formed by the anatexis of sillimanite garnet gneiss, and that the hypersthene-trondhjemite was formed by the anatexis of the leucocratic two-pyroxene plagioclase granulite. The U-Pb dating of the zircon indicates that the formation of the charnockite and granulite was related to the Archean-Proterozoic upwelling of a mantle plume (hot spot)around 2 500 Ma, in Yishui area, Shandong Province.

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    Some places in Henan Province are investigated by using sample surveys and interviews. Result shows that land circulation in less developed agricultural area of Henan Province has the characteristics of small scale,single form,short period,and circulation land in economic core region. Problems in land circulation are as follows:slow transfer of rural surplus labor force,hard implementation of fundamental land circulation,complicated mentality towards rural land circulation,many misgivings about land circulation,the unformed social service system of land circulation,and imperfect agricultural risk prevention mechanism for circulated land use. Based on the characteristics of land circulation,suggestions for promoting the land circulation of less developed agricultural areas are put forward in order to solve the problems in land circulation and to lay the foundation for effective implementation of land circulation,such as speeding up the development of urbanization,developing the circulation of collective land,effectively implementing the laws and regulations of rural collective land circulation,transferring land according to law,establishing market mechanism of agricultural land circulation,promoting the agricultural industrialization,establishing market mechanism of agricultural land circulation,promoting the agricultural industrialization,energetically readjusting rural industrial structure,and developing economy with local characteristics.

    The apparent ages of samples are obtained from fission track dating of apatite samples collected from the fault zones in Mabian area, southern Sichuan Province.In addition, thermal history is simulated from the obtained data by applying AFTSolve Program, to acquire the thermal evolution history of the samples.The result shows that tectonically the Mabian area was relatively stable between 25 and 3 Ma, compared to the inner parts and other marginal areas of the Tibetan Plateau.The studied area had little response to the rapid uplift events that occurred for several times in the Tibetan Plateau during 25-3 Ma.The latest thermal event related to the activity of the Lidian fault zone (about 8 Ma) is later than that of the Ebian fault zone (18-15 Ma ) to the west, indicating to some extent that the evolution of fault activity in the Mabian area has migrated from west to east.The latest extensive tectonic uplift occurred since about 3 Ma.As compared with the Xianshuihe fault zone, the Mabian area is closer to the eastern margin of the plateau, while the time of fast cooling event in this area is later than that in the southeast segment of the Xianshuihe fault zone (3.6-3.46 Ma).It appears to support the assumption of episodic uplift and stepwise outward extension of the eastern boundary of the Tibetan Plateau in late Cenozoic.

    Ningbo and its surrounding area is the forefront in the rapid economic development in the Yangtse delta, and the main production area for food supplies, cotton, edible oil and hemp;and at the same time, is the main area for wetland protection in Zhejiang Province. Our objectives were to quantify land cover change in Ningbo and its surrounding area from 1987 to 2000 and to analyze the causative factors of the change. Using 30-m resolution Landsat TM/ETM+ data and maximum likelihood classification method, we classified the study area into six land cover types: forest, agriculture, urban, freshwater, seawater and bottomland.The research results showed that significant changes in land cover occurred in the study area, and that agriculture and urban land cover change dominated most of the land cover change and were main causes for the changes of other types with human activities,such as urbanization, industrialization, etc. being the main factor while it was not very obvious whether climatic conditions have any role in the land cover changes. Agriculture, bottomland and other nature dominated land cover types are undergoing significant changes due to industrialization and urbanization, which threaten the stabilization of the environment. The study conclusion called for finding reasonable ways to solve the problems between land cover change and land use.

  7. Study on Rural Poverty in Ecologically Fragile Areas——A Case Study of the Tibetan Areas in Sichuan Province

    Institute of Scientific and Technical Information of China (English)

    2012-01-01

    This article offers an overview of natural environment, economic development, and social development in the Tibetan areas in Sichuan Province. The major manifestations of the status quo of poverty in the Tibetan areas are as follows: there is a wide range of poverty and a large poor population; the poverty degree is high and it is difficult to alleviate poverty; the natural disasters are frequent and the phenomenon of poverty arising from disasters is serious. We analyze the factors responsible for poverty of farmers and herdsmen in Sichuan Province as follows: first, the natural conditions are inclement and the ecological environment is fragile; second, the social attitudes are stale and the religious influence is deep; third, the development of education lags behind, the human capital inputs are short and the self-development capacity is weak; fourth, the state poverty alleviation and development policy is weakly directed at region; fifth, the Tibetan areas are facing the dilemma of choosing resources endowments or ecological protection. Following proposals are put forward to resolve the poverty issue in the Tibetan areas of Sichuan Province: strengthen infrastructure construction, and underpin self-development capacity of the Tibetan areas in Sichuan Province; reinforce organic connection of social security and poverty alleviation and development, and promote self-development capacity of impoverished farmers and herdsmen in the Tibetan areas; strengthen policy support, and improve self-development policy and mechanism of the Tibetan areas in Sichuan Province; drive the popularization of technology and culture in the Tibetan areas, and update the development concept of farmers and herdsmen in the Tibetan areas; accelerate the development of competitive industries in Tibetan areas, and promote economic development capacity of the Tibetan areas.

    This paper takes poverty-stricken county as the basic unit, and selects net income per peasant to study the poverty status in Hebei Province during 1986~2000.Temporal and spatial changes of povertystricken areas are analyzed. The result shows that poverty-stricken areas in Hebei Province distributed concentratedly and the areas decreased during 1986~2000, the net income per peasant was on the rise with an increasing speed in off-poverty counties being slightly higher than that in poverty-stricken counties, but the growth rate was extremely unstable,rising slowly in off-poverty counties while dropping in poverty-stricken counties. The main driving forces that influenced temporal and spatial changes were economic development of the whole province,ecological environment quality, infrastructure conditions and radiation of the key city. On this basis, some anti-poverty countermeasures suitable to local conditions are proposed.

    Full Text Available Anaplasma phagocytophilum is a zoonotic agent of public health importance, infecting both humans and animals. An investigation of the presence of Anaplasma phagocytophilum as well as Anaplasma platys was conducted in a forest area of Selenge province, Mongolia, where ticks are widely distributed and tick-borne diseases are highly endemic. Ticks were collected and tested using polymerase chain reaction based on groEL methodology. Anaplasma phagocytophilum was detected in 14 (6% of Ixodes persulcatus ticks and four (1% Dermacentor nuttalli ticks; infection of Anaplasma platys was detected in 1% of Ixodes persulcatus ticks and 10% of Dermacentor nuttalli ticks. The phylogenetic tree showed that the Anaplasma phagocytophilum clustered with the Russian group, most likely due to similar geographical locations. This finding is significant for both veterinary and public health officials given that these agents can cause both animal and human illness.

    Golestan Province, located in the south-east littoral of the Caspian Sea in northern Iran, has one of the highest rates of oesophageal cancer (OC) in the world. We review the epidemiologic studies that have investigated the epidemiologic patterns and causes of OC in this area and provide some suggestions for further studies. Oesophageal squamous cell carcinoma (OSCC) constitutes over 90% of all OC cases in Golestan. In retrospective studies, cigarettes and hookah smoking, nass use (a chewing tobacco product), opium consumption, hot tea drinking, poor oral health, low intake of fresh fruit and vegetables, and low socioeconomic status have been associated with higher risk of OSCC in Golestan. However, the association of tobacco with OSCC in this area is not as strong as that seen in Western countries. Alcohol is consumed by a very small percentage of the population and is not a risk factor for OSCC in this area. Other factors, such as polycyclic aromatic hydrocarbons, N-nitroso compounds, drinking water contaminants, infections, food contamination with mycotoxins, and genetic factors merit further investigation as risk factors for OSCC in Golestan. An ongoing cohort study in this area is an important resource for studying some of these factors and also for confirming the previously found associations. PMID:19800783

    The Tertiary Magmatic Province of Veneto, known as Veneto Volcanic Province (VVP), in the North-East of Italy, represents the most important volcanic distric of Adria Plate. It is composed by five volcanic bodies: Val d'Adige, Marosticano, Mts. Lessini, Berici Hills and Euganean Hills. Most of the volcanic products are relatively undifferentiated lavas and range in composition from nephelinites to tholeiites. Often VVP nephelinites and basanites carry mantle xenoliths (mainly harzburgites and lherzolite). This study reports petrological comparison between Marosticano xenoliths (new outcrop) and xenoliths from the Lessinean and Val d'Adige areas already studied by many Authors (Siena & Coltorti 1989; Beccaluva et al., 2001, Gasperini et al., 2006). Mineral major elements analyses show that the Marosticano lherzolites and harzburgites reflect "more restitic" composition than the mantle domain beneath the other VVP districts (Lessini Mts. and Val d'Adige). In fact, olivine and pyroxene of Marosticano xenoliths have the highest mg# values of the entire district (Marosticano→90-93; literature→86-92). At comparable mg# (45-85 wt%) Marosticano spinels tend to be higher in Cr2O3 (23-44 wt%) contents with respect to the other VVP sp (7-25 wt%). It is worth noting that, Ni contents of Marosticano olivines in both harzburgites and lherzolites are higher (2650-3620 ppm) than those of the Lessinean xenoliths (1500- 3450 ppm), and similar to that of Val d'Adige lherzolites (3000-3500 ppm), approaching the contents of Archean cratonic mantle (Kelemen, 1998). In turn, Lessinean olivines properly fall in the Ni-mg# Phanerozoic field. At fixed pressure of 15 kbar, the equilibration temperature of Marosticano xenoliths are similar (Brey & Köhler: 920-1120°C) to those of Lessini (O'Neill & Wall: 990-1110°C; Beccaluva et al., 2007), but higher than those of Val d'Adige (Wells: 909-956°C; Gasperini et al., 2006). Finally, Marosticano mantle fragment show similar relatively high

    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.

  16. Estimation of the resident's additional dose in bone-coal mining areas of the five provinces

    International Nuclear Information System (INIS)

    This paper introduces the resident's additional dose in bone-coal mining areas. The increase of the annual additional effective doses accepted by the residents living in the carbide-brick houses, the staffs working in the carbide-brick houses and the miners working in the bone-coal mining areas of Hubei, Hunan, Jiangxi, Zhejiang and Anhui Provinces is caused by the rising of environmental radioactive level. The investigation of natural background radiation in the bone-coal mining areas indicated that both mining and utilizing bone-coal cause the rise of environ- mental radioactive level. The ranges of the annual additional effective dose accepted by the residents, staffs and miners is 1.9-6.8 mSv, 0.5-2.0 mSv and 8.2-71 mSv, and with an average of 3.8 mSv, 1 mSv and 40 mSv, respectively. The annual additional effective doses accepted by part residents and staffs exceed the dose limit of 1 mSv for public exposure, and part miners exceed the dose limit of 20 mSv for occupational exposure. And the contribution of dose caused by inhaled radon to the total additional effective dose is over 76%. (authors)

    A nationwide need for information characterizing hydrologic conditions in mined and potential mine areas has become paramount with the enactment of the Surface Mining Control and Reclamation Act of 1977. This report, one in a series covering the coal provinces nationwide, presents information thematically by describing single hydrologic topics through the use of brief texts and accompanying maps, graphs, or other illustrations. The summation of the topical discussions provides a description of the hydrology of the area. Area 54, in north-central Colorado and south-central Wyoming, is 1 of 20 hydrologic reporting areas of the Northern Great Plains and Rocky Mountain coal provinces. Part of the Southern Rocky Mountains and Wyoming Basin physiographic provinces, the 8,380-square-mile area is one of contrasting geology, topography, and climate. This results in contrasting hydrologic characteristics. The major streams, the North Platte, Laramie, and Medicine Bow Rivers, and their principal tributaries, all head in granitic mountains and flow into and through sedimentary basins between the mountain ranges. Relief averages 2,000 to 3,000 feet. Precipitation in the mountains may exceed 40 inches annually, much of it during the winter, which produces deep snowpacks. Snowmelt in spring and summer provides most streamflow. Precipitation in the basins averages 10 to 16 inches annually, insufficient for sustained streamflow; thus, streams originating in the basins are ephemeral. Streamflow quality is best in the mountains where dissolved-solids concentrations generally are least. These concentrations increase as streams flow through sedimentary basins. The increases are mainly natural, but some may be due to irrigation in and adjacent to the flood plains. In the North Platte River, dissolved-solids concentrations are usually less than 300 milligrams per liter; in the Laramie and the Medicine Bow Rivers, the concentrations may average 500 to 850 milligrams per liter. However

    Tibetan areas in Sichuan province include Ganzi Tibetan Autonomous Prefecture , Aba Tibetan and Qiang Prefecture , Muli Tibetan Autonomous County , and some Tibetan Autono-mous Townships scattered in Mianning County , Yuexi County , Ganluo County of Liangshan Yi Autonomous Prefecture , Baoxing County of Ya ’ an District, Pingwu County and Beichuan County of Mianyang District . Among these areas , Ganzi Prefecture and Aba Prefecture are the main Tibetan areas in Sichuan province . The stability and de-velopment of Tibetan areas in Sichuan Province are important for the stability of the Tibetan Region and even for the entire country.Historically, an important cause for the bloody conflicts and insta-bility of this region was the competition over the re-sources in the grasslands and border areas . For several decades after democratic reform , the num-bers of these kinds of criminal conflicts maintained a fixed level, and did not increase .This was ob-viously due to an overall lag of national economic development together with strong governmental con-trol.However, during the recent decade , rapid economic and social development in this Tibetan area of Sichuan and the diversification of the bene-fit structure became one of the main reasons for the increase in these kinds of criminal conflicts .The cause of these conflicts include the competition o-ver resources , such as the grasslands , Chinese caterpillar fungus , matsutake mushrooms , with neighboring provinces , counties , township or vil-lages.The conflicts are also caused by environ-mental issues resulting from present economic de-velopment projects , such as hydroelectric develop-ment , sand excavation and mining explorations . There are also conflicts due to traffic accidents , medical disputes and other events .These conflicts are always followed by serious consequences , in-cluding the loss of life and personal injury , the loss of property etc .Some cases are very difficult to resolve and control .In

    The total mercury (T-Hg) and methyl mercury (Me-Hg) concentrations in the hair were measured to evaluate mercury (Hg) exposure for the residents in Da-shui-xi Village (DSX) and Xia-chang-xi Village (XCX) in the Wanshan Hg mining area, Guizhou Province, Southwestern China. The mean concentrations in the hair of DSX residents were 5.5 ± 2.7 μg/g and 1.9 ± 0.9 μg/g for T-Hg and Me-Hg, respectively. The concentrations in the hair of XCX residents were 3.3 ± 1.4 μg/g and 1.2 ± 0.5 μg/g for T-Hg and Me-Hg, respectively. Hair Me-Hg concentrations were significantly correlated to T-Hg (r = 0.42, P < 0.01) in the two sites; on average, hair Me-Hg concentration accounted for 40 and 44% of T-Hg for DSX and XCX residents, respectively. Age has no obvious correlation with hair Hg and the hair Hg levels showed a significant gender difference, with higher T-Hg and Me-Hg concentrations in the hair from males than females. The rice collected from the two sites showed high levels of T-Hg and Me-Hg concentration. The results indicated a certain Hg exposure for the residents in DSX and XCX in the Wanshan Hg mining area.

    The biomineralization process of iron oxidizing bacteria and its influence on accumulation of metals were investigated by modern biological observation techniques (i.e., SEM and TEM) and geochemical methods, in coastal area of Zhoushan Island, Zhejiang province where a thick ancient wood layers were buried, Results show that the iron mud samples mainly contain Leptothrix-like sheaths and Gal-lionella-like stalks, which are known as neutrophilic iron-oxidizing bacteria. These two bacteria are present as obviously different abundance in two sampling sites, which may be regulated by the geo-chemistry of seepage water. The biomineralization product of iron oxidizing bacteria is ferrihydrite, a poorly ordered iron oxide, and formation of amorphous mineral is affected by the factors of bacteria, minor Si and temperature preventing any further transformation into more crystalline phases. Organic functional groups, extracellular polymers and surface charges can provide favorable nucleation sites or template for formation of iron precipitates on the bacterial surface. The mineralization process of the iron oxidizing bacteria is divided into different stages,i.e., extracellular mineralization, intracellular mineralization and the whole cell mineralization. Furthermore, due to BIOS containing the bacterial organic matter, the accumulation capacity of metals specially Fe and Co is highly increased, suggest-ing that BIOS exert a degree of controlling in the cycling of metal elements in seepage area.

    Full Text Available Povinding quality health care services, without constant qualitative and quantitative studeies/evaluation, seem to be impossible. High rate of children immunization coverage in Iran, however, represents parts of a quality assessment of mother and child health care services in rural areas of West-Azerbaijan Province, Iran. In this cross-sectional study, LQAS method was employed for the purpose of quality assessment. Children between 10 to 36 months old from the pre-mentions areas constitute the study population of present report. Sample was selected through a multistage sampling method and a questionnaire together with a checklist was utilized for data collection. Findings demonstrate a very high rate immunization coverage of children (>96%. Mother’s knowledge about the data of next vaccination and DPT potential side effect's are estimated to be 32%, and 58%, respectively. Children's overall immunization adequacy rate, despite the high rate coverage, equalled to 59% which does not represent a high quality service in this respect. This study approves the reliability and practicality of LQAS method for quality assurance of health services.

    Hydrologic information and analysis are needed to aid in decisions to lease Federally owned coal and for the preparation of the necessary Environmental Assessments and Impact Study Reports. This need has become even more critical with the enactment of the Surface Mining Control and Reclamation Act of 1977 (Public Law 95-87). This report, one in a series of nationwide coal province reports, presents information thematically by describing single hydrologic topics through the use of brief texts and accompanying maps, graphs, or other illustrations. The report broadly characterizes the hydrology of Area 53 in northwestern Colorado, south-central Wyoming, and northeastern Utah. The report area, located primarily in the Wyoming Basin and Colorado Plateau physiographic provinces, consists of 14,650 square miles of diverse geology, topography, and climate. This diversity results in contrasting hydrologic characteristics. The two major rivers, the Yampa and the White Rivers, originate in humid granitic and basaltic mountains, then flow over sedimentary rocks underlying semiarid basins to their respective confluences with the Green River. Altitudes range from 4,800 to greater than 12,000 feet above sea level. Annual precipitation in the mountains, as much as 60 inches, is generally in the form of snow. Snowmelt produces most streamflow. Precipitation in the lower altitude sedimentary basins, ranging from 8 to 16 inches, is generally insufficient to sustain streamflow; therefore, most streams originating in the basins (where most of the streams in coal-mining areas originate) are ephemeral. Streamflow quality is best in the mountains where dissolved-solids concentrations generally are small. As streams flow across the sedimentary basins, mineral dissolution from the sedimentary rocks and irrigation water with high mineral content increase the dissolved-solids concentrations in a downstream direction. Due to the semiarid climate of the basins, soils are not adequately leached

    Landsat TM data were used for lithological discrimination and mapping in the little-known, semiarid 900 km 2 area around Caraculo station and the middle course of the Rio Giraul (Namibe Province, SW Angola) following two main procedures. The first of these was based on visual evaluation of three-band composites, band-ratio composites and Principal Component Analysis. The second method relied on the extraction of spectral signatures, and their use to obtain automatic classifications. Satisfactory results were reached with the first procedure, thus allowing - with limited support of ground information — the draft of a lithological map, while the second method was not systematically efficient, even for confirmation of data acquired with the first procedure. Image interpretation suggests that an extensive but hithertoun differentiated metasedimentary complex consisting of a heterogeneous supracrustal sequence should be subdivided into at least two units. Field observations proved that one of these is marked by a notable frequency of marbles and the other is characterized by a widespread occurrence of amphibolitic bodies. Moreover, a belt of undetermined (thermally metamorphosed ?) metamorphic rocks is interposed between them. The distinction of so far unidentified units, though restricted to interpretation of processed Landsat TM data, has significant geological implications also in the regional context and will be helpful in guiding future work with conventional geological methods.

    In order to evaluate the soil erosion rate for different land uses and make recommendations on land-use alternatives for erosion control in hilly and mountain areas on a Purplish soil (Regosols in FAO taxonomy), experimental data were obtained from three continuously monitored sites located at Yanting,Nanbu and Pengxi of Sichuan province. The data showed that the rank of erosion rate is farmland >unfenced grassland > fenced grassland > forestland.The erosion rate of farmland was more than 3 times higher than that of forestland and fenced grassland,indicating that restricting human activity is crucial for over-erosion. The erodibility was higher at the initial period of rainy season for all the three types of land use. The erosion rates of fenced grassland and mature afforestation land were not proportional to rainfall intensity because these land uses changed impact energy of the rainfall. This research showed that restricting human activity, intensifying the management of initial period of rainy season, and increasing the cover rate of land surface are the three major measures for soil erosion prevention. It is recommended that farmers should cease cultivation on farmland at the top of hills and steep slope land return those lands back to grassland or forestland.

    The hydrogeology of the Basin and Range Physiographic Province in parts of Arizona, California, New Mexico, Utah, and most of Nevada was classified at basin and larger scales to facilitate information transfer and to provide a synthesis of results from many previous hydrologic investigations. A conceptual model for the spatial hierarchy of the hydrogeology was developed for the Basin and Range Physiographic Province and consists, in order of increasing spatial scale, of hydrogeologic components, hydrogeologic areas, hydrogeologic flow systems, and hydrogeologic regions. This hierarchy formed a framework for hydrogeologic classification. Hydrogeologic areas consist of coincident ground-water and surface-water basins and were delineated on the basis of existing sets of basin boundaries that were used in past investigations by State and Federal government agencies. Within the study area, 344 hydrogeologic areas were identified and delineated. This set of basins not only provides a framework for the classification developed in this report, but also has value for regional and subregional purposes of inventory, study, analysis, and planning throughout the Basin and Range Physiographic Province. The fact that nearly all of the province is delineated by the hydrogeologic areas makes this set well suited to support regional-scale investigations. Hydrogeologic areas are conceptualized as a control volume consisting of three hydrogeologic components: the soils and streams, basin fill, and consolidated rocks. The soils and streams hydrogeologic component consists of all surface-water bodies and soils extending to the bottom of the plant root zone. The basin-fill hydrogeologic component consists of unconsolidated and semiconsolidated sediment deposited in the structural basin. The consolidated-rocks hydrogeologic component consists of the crystalline and sedimentary rocks that form the mountain blocks and basement rock of the structural basin. Hydrogeologic areas were

    Keshavarzi, B.; Moore, F.

    2009-04-01

    The environmental impacts of gold mining and processing on geochemical and biogeochemical cycles in Muteh region located northwest of Esfahan province and northeast of Golpaygan city is investigated. For this purpose systematic sampling was carried out in, rock, soil, water, and sediment environments along with plant, livestocks and human hair samples. Mineralogical and Petrological studies show that ore mineral such as pyrite and arsenopyrite along with fluorine-bearing minerals like tremolite, actinolite, biotite and muscovite occur in green schist, amphibolite and lucogranitic rocks in the area. The hydrochemistry of the analysed water samples indicate that As and F display the highest concentrations among the analysed elements. Indeed arsenic has the highest concentration in both topsoil and subsoil samples when compared with other potentially toxic elements. Anthropogenic activity also have it s greatest effect on increasing arsenic concentration among the analysed samples. The concentration of the majority of the analysed elements in the shoots and leaves of two local plants of the region i.e Artemesia and Penagum is higher than their concentration in the roots. Generally speaking, Artemesia has a greater tendency for bioaccumulating heavy metals. The results of cyanide analysis in soil samples show that cyanide concentration in the soils near the newly built tailing dam is much higher than that in the vicinity of the old tailing dam. The high concentration of fluorine in the drinking water of the Muteh village is the main reason of the observed dental fluorosis symptoms seen in the inhabitants. One of the two drinking water wells which is located near the metamorphic complex and supplies part of the tap water in the village, probably has the greatest impact in this regard. A decreasing trend in fluorine concentration is illustrated with increasing distance from the metamorphic complex. Measurements of As concentration in human hair specimens indicate that As

    To understand the ecophysiological adapta-tion of Lilium "Oriental Hybrids", which are grown for their commercial bulbs, the gas exchange, leaf N and chlorophyll content of the three varieties were investigated in the central areas of the Yunnan Province. Among the three varieties, light-saturated photosynthetic rate at ambient CO2 (Amax) of Tiber was the highest, while that of Siberia was the lowest. The difference in the Amax was related to the carboxylation efficiency (CE), leaf mass per unit area and leaf N content per mass, which indicated that their photosynthetic capacity was influenced by the activity and/or the quantity of Rubisco. The three vari-eties had lower photosynthetic saturation points and pho-tosynthetic compensation points, but the photosynthetic rates were not decreased up to 2000 μmol.m-2s-1 of the light intensity. This indicates that the three varieties had broad adaptability to light intensity. There were signifi-cant differences in the photosynthetic optimum temper-ature among the three varieties. Siberia had the highest photosynthetic optimum temperature (25.5℃-34.9℃), and is likely to grow well in warm areas. Sorbonne had the lowest photosynthetic optimum temperature (19.3℃-25.6℃), and its growth is favored in cool areas. Tiber can maintain a high photosynthetic rate within a wide range of temperature. Therefore, Tiber is the most suitable variety for the climate in the central areas of the Yunnan Province, China.

    Full Text Available Soil-inhabiting nematodes, including plant-parasitic nematodes, are considered to be the most abundant multicellular organisms in the soil, and of particular interest since they are an integral part of the interlocking chain of nutrient conversions. Because of their abundance and relative susceptibility to both physical and chemical changes, these organisms are used as indicator organisms. The National Collection of Nematodes (NCN consists of a core collection, the Meloidogyne Collection and the Juan Heyns Collection, which are housed at the Plant Protection Research Institute of the Agricultural Research Council in Pretoria. Vast amounts of biodiversity data are contained in NCN, and the digitising of the collection from 2007 to 2014 yielded unpublished locality information, especially datasets of plant nematodes reported from protected areas of the Eastern Cape. Two hundred and thirty plant nematode species belonging to 36 genera were reported from the Eastern Cape. Of these, only 80 were from protected areas, whilst 163 were from uncultivated areas (outside protected areas and 148 from cultivated areas. Ten species were described from protected areas, namely Criconemoides silvicola, Meloinema silvicola, Ogma tuberculatum, Paralongidorus cebensis, Paralongidorus hanliae, Scutellonema tsitsikamense, Trichodorus vandenbergae, Xiphinema erriae, Xiphinema ornatizulu and Xiphinema simplex. Only M. silvicola, O. tuberculatum, P. cebensis and S. tsitsikamense were not reported from other provinces, suggesting endemism.Conservation implications: The diversity of nematode fauna is not adequately protected as most nematode biodiversity in the Eastern Cape lies outside protected areas, with only 80 of the 230 plant-feeding nematode species in the province being reported from protected areas.

    Full Text Available The most widely-spread type of a rural dwelling-house in the Hainan province presenting the most populated part of China is a «Siheyuan» country estate. Its lay-out structure contains an open internal courtyard and all the buildings are practically always located symmetrically relative to a central axis on the sides of the courtyard. The Siheyuan composition permits to divide it in elements which are convenient for a separate construction and for being connected in multi-element block-schemes.  In this connection the designing block-module method can be recommended as the most prospective one for improvement of the methodology for designing rural dwelling houses. Their large-scale construction on the valley territories of the Hainan province is planned by the leadership of the People’s Republic of China.

    Water scarcity and water pollution are severe problems in the Northern part of China, strongly affecting socio-economic development and standards of living and environment. The Shandong province is specifically plagued by water scarcity. In the coastal catchments of the Shandong province the water scarcity is even increased due to saltwater intrusion, reducing the usability of water resources available. The pressing water problems in the costal catchments in the Shandong province and resulting socio-economic troubles forced the Chinese authorities to implement a variety of measures to relieve water scarcity and abate saltwater intrusion. But not much has been achieved so far as the measures are not coordinated in their effects and cost-benefit relations have not been considered sufficiently. Such a situation calls for good, which means integrated, sustainable water management. The assessment of this situation in the project "Flood Control and Groundwater Recharge in Coastal Catchments" financed by the German Ministry of Research and Education is presented. Further objectives and first ideas for an IWRM-concept are explained. These ideas are based on concepts developed in Germany in the context of the fulfilment of the European Water Framework Directive.

    Full Text Available The most important environmental pollutant in steel industry is air pollution due to the process of its products. Optimise sitting for this industry, in a great extend will prevent pollutants and emissions. Khorasan Steel Company is located near some populous villages and three rivers. It is necessary to perform an investigation for providing abatement and control of air pollution, in time of planning and manufacturing of control instruments. The manufacturing company has determined air pollution reduction instruments in this site, according to the emission suspended particulate and its climatic conditions. The air pollution reducer's instruments were used back-fither. But, this offer was not agreed by the Department of the Environment of Iran. Perhaps, this disagreement was announced just for another original problem, which was the site selection of plants. This research was on the filtration which has been offered by the manufacturing company, if this selection can improve the future regional air pollution. These figures, of course, were obtained from the present data and plume rise particulate, considering Gausian distribution mode for all the rural population and rivers rounding to the site, up to 5 km. The results showed that the produced particulates were less than permissible limit and the proposed methods will improve the complex air pollution difficulties So, the proposed methods were provided for increasing the control and operating the system for conducting of cyclone before input of particulate to the back-filter.

    In order to explore input pathways and pollution characteristics of Cd contamination in paddy soil in Youxian, Hunan Province, Cd contents in paddy soils, sediments of irrigation canals, typical mineral and industrial products such as coal, gangue and cement were analyzed. It was suggested that the average contents of Cd both in surface paddy soil and the corresponding natural soil were higher than the soil quality standard 0.3 mg x kg(-1). Cd contents in gangue and cement were similar as those in the corresponding natural soils. The atmosphere deposition of Cd was the highest in factory area. The profiles of Cd in 0-100 cm paddy soil and 0-40 cm in natural soils varied significantly from the upper to the lower layer. Cd contents in 0-40 cm layer in paddy soil were much higher than those in corresponding natural soils in mineral and mineral-factory areas. The potentiality for downward movement of Cd in soils in mineral area was the highest among the three studied areas. It suggested Cd contents in surface paddy soil were higher in upwind areas than those in downwind areas in mineral-factory and factory areas. It could be concluded that the main input pathways of Cd in mineral and mineral-factory. areas were from irrigation water, while contribution of atmosphere deposition in mineral-factory and factory areas was also very significant.

    Full Text Available Khorasan wheat is an ancient grain with previously reported health benefits in clinically healthy subjects. The aim of this study was to examine whether a replacement diet, thereby substituting all other cereal grains, with products made with organic khorasan wheat could provide additive protective effects in reducing lipid, oxidative and inflammatory risk factors, in patients with Acute Coronary Syndromes (ACS in comparison to a similar replacement diet using products made from organic modern wheat. A randomized double-blinded crossover trial with two intervention phases was conducted on 22 ACS patients (9 F; 13 M. The patients were assigned to consume products (bread, pasta, biscuits and crackers made either from organic semi-whole khorasan wheat or organic semi-whole control wheat for eight weeks in a random order. On average, patients ingested 62.0 g dry weight (DW day−1 khorasan or control semolina; and 140.5 g DW day−1 khorasan or control flour, respectively. An eight-week washout period was implemented between the respective interventions. Blood analyses were performed both at the beginning and end of each intervention phase; thereby permitting a comparison of both the khorasan and control intervention phases, respectively, on circulatory risk factors for the same patient. Consumption of products made with khorasan wheat resulted in a significant amelioration in total cholesterol (−6.8%, low-density lipoprotein cholesterol (LDL-C (−8.1% glucose (−8% and insulin (−24.6% from baseline levels, independently of age, sex, traditional risk factors, medication and diet quality. Moreover, there was a significant reduction in reactive oxygen species (ROS, lipoperoxidation of circulating monocytes and lymphocytes, as well as in the levels of Tumor Necrosis Factor-alpha. No significant differences from baseline in the same patients were observed after the conventional control wheat intervention phase. The present results suggest that a

    Experiments were conducted during 2007-2008 at the Zhangbei Agricultural Resource and Ecological Environment Key Field Research Station, Hebei Province, China to study water-efficient pumpkin planting patterns in this area. Four treatments of pumpkin and oil sunflower intercropping were used to study the problem of water resource scarcity and inefficient water use in the plateau of northern Hebei Province. The four treatments were: pumpkin sole cropping (Sp), oil-sunflower sole cropping (So), intercropp ing one row oil sunflower (IC1) or two rows (IC2) between pumpkin rows. The results showed that oil sunflower competed for soil water with pumpkin during late growth stage of pumpkin in IC2, but there was no water competition in IC1. Total rainfall during the growing season was 201.6mm and the soil water balance differed between treatments. In all cases the water percolation was low and soil moisture storage always negative. Nearly all water loss was through evapotranspiration, which varied by treatment. The seasonal evapotranspiration of IC1 was less than So, Sp and IC2, 46.57%, 41.22% and 46.73%, respectively. Economic yield of pumpkin decreased from 30.00% (IC1) to 71.42% (IC2). However, yield per plant of intercropping oil sunflower increased from 190.71% to 241.26%. as compared with So, because oil sunflower showed remarkably partial advantage. The Land Equivalent Ratio (LER) of pumpkin-oil sunflower was 1.08-1.22, and the Water Equivalent Ratio (WER) of pumpkin-oil sunflower was 1.07-1.26. Economic value of sole pumpkin was greatest but did not differ from treatment IC1. Other treatments had significantly less economic value. In this region of rain-fed dry land farming, a sparse planting of sole pumpkin with high efficiency production could realize water resources most effectively in the Plateau of northern Hebei Province.

    Objective Mercury (Hg), as one of the priority pollutants and also a hot topic of frontier environmental research in many countries, has been paid higher attention in the world since the middle of the last century. Guizhou Province (at N24°30′-29°13′, E103°1′-109°30′, 1 100 m above the sea level, with subtropical humid climate) in southwest China is an important mercury production center. It has been found that the mercury content in most media of aquatics, soil, atmosphere and in biomass of corns, plants and animals, is higher than the national standard.The present study aims to explore the influence of mercury pollution on the health of local citizens. Methods The effect of rice from two mercury polluted experimental plots of Guizhou Province on the expression of c-jun mRNA in rat brain and c-jun protein in cortex, hippocampus and ependyma was observed using reverse transcription polymerase chain reaction (RT-PCR) and immunocytochemical methods. Results The results showed that the mercury polluted rice induced expression of c-jun mRNA and its protein significantly. Selenium can reduce Hg uptake, an antagonism between selenium and mercury on the expression of c-jun mRNA and c-jun protein. Conclusion c-jun participates in the toxicity process of brain injury by mercury polluted rice, the expression of c- jun mRNA in brain, and c-jun protein in rat cortex and hippocampus can predict neurotoxicity of mercury polluted rice. People should be advised to be cautious in eating any kind of Hg-polluted foods. To reveal the relationship between c-jun induction and apoptosis, further examinations are required.

In addition, the specific activities of 238U and 226Ra in air aerosol samples from the bone-coal mine areas were 0.6 and 0.5 mBq/m3, respectively. (authors)

  16. Numerical simulation for the coupling effect of local atmospheric circulations over the area of Beijing,Tianjin and Hebei Province

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    Using the model system MM5.V3 and multi-layer grid nesting technique, we have done a multi-scale numerical simulation over the area of Beijing, Tianjin and Hebei Province to analyze the temperature and wind field there and study its local circulations. The results show a coupling effect of Urban Heat Island Circulation (UHIC), Mountain Valley Breeze (MVB) and Sea Land Breeze (SLB) occurs in this area when the synoptic system is weak. The SLB can penetrate deep into the mainland for about 200 km when it is blooming. MVB can extend to south and cover almost the whole plain area in Beijing. Both MVB and SLB are diurnal periodical; meanwhile the phase of MVB drops behind that of SLB for about six hours. As a local circulation, the UHIC weakens the two circulations above, and it also has a diurnal period. As a result, the coupling effect of circulations reveals not only different features in spring-summer period and autumn-winter period in a year but also the difference between early morn- ing to noonday and afternoon to night in a day. We noted the diffusion of contamination over the area around Beijing, and found the steady presence of a transport routine of contamination over North-China throughout the year caused by the Coupling Effect mentioned above. This find is important for studying the environment pollution in this area.

  17. SHRIMP zircon U-Pb dating and its geological significance of Chibaisong gabbro in Tonghua area, Jilin Province,China

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    SHRIMP zircon U-Pb dating for Chibaisong No.1 gabbro in the Tonghua area, Jilin Province, is discussed in the paper. The cathodoluminescence (CL) images of the zircons indicate that they can be divided into two major types, i.e. euhedral-subhedral one with striped absorption and round one with obvious oscillatory zoning rims. The dating results of the zircons suggest that Chibaisong gabbro in the Tonghua area was formed at 134±7Ma-the Early Cretaceous. The concordia ages of 2497±13Ma, 787±35Ma, 321±10Ma, 217±11Ma of zircons imply that the Tonghua area might geologically be located in the convergent region of the Yangtze Block (YB) and the North China Block (NCB) in the early Mesozoic and the zircons should be caught during magma intrusion. The existence of the Early Cretaceous basic dyke swarm in the Tonghua area shows that an intensive extensional environment occurred in the Early Cretaceous. It is suggested that the magmatism and lithospheric extension in the Tonghua area should be related to the subduction of the Pacific plate.

    Using the model system MM5.V3 and multi-layer grid nesting technique,we have done a multi-scale numerical simulation over the area of Beijing,Tianjin and Hebei Province to analyze the temperature and wind field there and study its local circulations.The results show a coupling effect of Urban Heat Island Circulation (UHIC),Mountain Valley Breeze (MVB) and Sea Land Breeze (SLB) occurs in this area when the synoptic system is weak.The SLB can penetrate deep into the mainland for about 200 km when it is blooming.MVB can extend to south and cover almost the whole plain area in Beijing.Both MVB and SLB are diurnal periodical;meanwhile the phase of MVB drops behind that of SLB for about six hours.As a local circulation,the UHIC weakens the two circulations above,and it also has a diurnal period.As a result,the coupling effect of circulations reveals not only different features in spring-summer period and autumn-winter period in a year but also the difference between early morning to noonday and afternoon to night in a day.We noted the diffusion of contamination over the area around Beijing,and found the steady presence of a transport routine of contamination over North-China throughout the year caused by the Coupling Effect mentioned above.This find is important for studying the environment pollution in this area.

The objective of this study was the assessment of riboflavin status of rural school children in Kerman province and its relationship with riboflavin, protein and energy intake. Methods: In this cross-sectional study, 327 primary school children were randomly selected by the stratified multistage cluster sampling method. Variables for classifications were sex and socio-economic status (according to the educational level. This study was conducted by the Department of Nutrition and Biochemistry of School of Public Health in Tehran University in the winter of 2001. A twenty-four hour recall questionnaire was completed by and 5 cc of venous blood was taken from each student. Riboflavin status was assessed by measuring the glutathione reductase activity coefficient (EGR – AC of the red blood cells. Chi-Square and Pearson’s correlation coefficient tests were used to determine correlations. Student’s t–test was used to show the differences in the mean of EGR – AC between the classifications of independent factors. Results: The relationship between riboflavin status and its independent variables including the status of riboflavin, protein and calorie intake were assessed. Outputs of the study indicated that 39.7% of the boys and 43.6% of the girls (41.8% together were marginally riboflavin deficient. Furthermore, 37.7% of the boys, 33.4% of the girls (35.4% together were frankly riboflavin deficient. An average of 67.2% of the children (70.1% boys, 63.7% girls had enough intake of riboflavin, and 76.2% of the children (79.9%, boys, 72.5% girls had adequate intake of protein. However, only 22% of the children (24.5% boys, 19.3% girls had sufficient caloric intake. Outputs of this dietary evaluation reveal that there is a relationship

    Full Text Available The genus Carex L. is one of the largest genera (2000 spp. of the flowering plants . There are 85 species of Carex in Iran plateau that approximately half of them are present in Iran. In this study, stem and leaf anatomy of 12 species and subspecies of Carex from two subgenera, Carex and Vignea, were investigated using hand cutting method and blue toluidine staining. The results showed that some of anatomical features such as, location of vascular bundles, size of air cavities, type of triangular stem, number of sclerenchyma layer and amount of lignified stem and cuticle thickness were effective in determining the species. This study did not confirm the classical taxonomy based on morphological characteristics and the results revealed that anatomical characteristics were correlated with plant water conditions.

  3. Patient organ doses from CT scan examinations in eleven state owned hospitals of Khorasan Province of Iran

    International Nuclear Information System (INIS)

    Full text: CT is a high dose technique; it involves higher patient doses than most conventional X-ray examinations. It is important that CT exposure parameters are optimized and ALARA principle is observed, however high image quality is maintained. A comple mentary approach to the in-air or in phantom measurements is to measure ESD by TLD. Methods In this study we have investigated radiation exposure of 341 patients at II hospitals. Organ and effective doses were estimated for all patients who underwent CT examination of brain by ImPACT software. ESD of same patients were measured by TLD-I 00. Brain examinations were performed with fixed kV, mA and T for all scanners. Results Patients who were scanned by Toshiba XVTdmachine received maximum brain dose (33.5 mGy), on the other hand GE Highlight scanner gave rise to minimum brain dose (12.7 mGy). Average effec tive dose of patients included in this work was 0.85 0.23 mSv which is smaller than the corresponding value (1.81 0.24 mSv) reported by NRPB. Scanning by Toshiba XVTD gave rise to maximum ESD (29.8 mGy). On the other hand minimum ESD (5.65 mGy) was achieved when patients were scanned by GE Hilight machine. Conclusion The dosimetric quantities presented in this study provide a valuable tool for the optimization of Head CT protocols in the region. The radiation dose to a particular organ from any given CT test depends on: number of scans, mAs, patient's size, axial scan range, kVp, and scanner design. Many of these factors are contro lable (Table I).

    Full Text Available Numerous studies have been done to obtain a written pattern in order to determine auditing quality since 1981 following documentation of auditing quality according to company size by Linda De Angelo. Multiple factors such as auditing company size, tenure period of auditor and report type were applied in various investigations to determine quality. Recently, the tendency to evaluate factors affecting auditing quality has been increased among researchers due to the change of demands of auditor services. Pattern of internal studies have indicated that a company's size (organization as big and society as small and tenure period of an auditor are the main factors in studies. Divergent findings have been obtained. In this paper a company’s size is considered as auditing quality scale. We examined the two proposed hypothesis using statistical logistic regression and multivariate regression. Tests were conducted using real data related to 155 companies chosen from those companies accepted in Tehran stock exchange during (2004-2009, in these tests the known software SPSS and LISREL were used.

    2000-01-01

    @@The Mianluening area, Shaanxi Province, China, located between the Qinling-Yangtze plate and Songfan-Ganzi fault zone, is an important base of multi-metal mineral resources.Since the Late Archean, the mineralization process has been complicated by multi-tectonic movements, multi-age magma heat events, multi-age metamorphism and deformation. In this case, the complex mineralization background has made it difficult to establish the linear quantitative forecasting model.The line and loop structure of TM remote-sensing is classified as four groups: the east-west and north-east structures containing deposits, the south-north structure restricting deposits and the north-west structure. Positive and negative magnetic fields are associated with these structures.

  7. Using Remote Sensing Data to Delineate the Lineaments for Hydrothermal Mineral Prediction in Heqing Area, Northwest Yunnan Province, China

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Lineament extraction and analysis is one of the routine work in mapping medium and large areas using remote sensing data, most of which are satellite images. Landsat Enhanced Thematic Mapper (ETM) of 945×1 232 pixels subscene acquired on 21 March 2000 covering the northwestern part of Yunnan Province has been digitally processed using ER Mapper software. This article aims to produce lineament density map that predicts favorable zones for hydrothermal mineral occurrences and quantify spatial associations between the known hydrothermal mineral deposits. In the process of lineament extraction a number of image processing techniques were applied. The extracted lineaments were imported into MapGIS software and a suitable grid of 100 m×100 m was chosen. The Kriging method was used to create the lineament density map of the area. The results show that remote sensing data could be useful to extract the lineaments in the area. These lineaments are closely correlated with the faults obtained through other geological investigation methods. On comparing with field data the lineament-density map identifies two important high prospective zones, where large-scale deposits are already existing. In addition the map highlights unrecognized target areas that require follow up investigation.

    High concentrations of arsenic were determined in sediments from the Kouhsorkh area, Khorasan province, NE Iran. The main rock formations in the area consist of Tertiary volcanic rocks as Tuffaceous sandstone, polymictic conglomerate and andesite. Furthermore, some As-Sb-Au mineralization occurred in this area. Concentrations of arsenic in sediments were determined to range between 4.2 and 268.2 ppm, exceeding US EPA (2004) limits. It seems that young volcanic activity is one of the most important factors for arsenic contamination in this area. The first stage of this medical geology study was done at 2 villages in the Kouhsorkh area in which the arsenic concentration in water is high. People in this residential area suffer from skin diseases including hyperpigmentation, hypopigmentation, keratosis on head, hands, and feet. The 24-h urine specimens were tested for arsenic, the level of total arsenic in urine were determined to range between 13.66 and 75.92 μg/l day, exceeding permissible limits from 5 to 40 μg/day. More systematic studies are needed to determine the link between As exposure and its related diseases. PMID:21960314

    The Zhangcunping area is located at the north limb of the Huangling anticline in Yichang, Hubei Province. Here, the sedimentary succession of the Ediacaran Doushantuo Formation is similar with that in the Weng'an area, Guizhou Province. A large number of new microfossils (mainly acanthoacritarchs) from the Doushantuo Formation in this area are reported in this paper. The fossil assemblage shows similarity as the phosphatized biota of the Doushantuo Formation at Wang'an, Guizhou Province and the silicified biota of the Doushantuo Formation at the Yangtze Gorges, which suggests that the Zhangcunping area is a key for correlation of the Doushantuo Formation between the Weng'an area,Guizhou Province and the Yangtze Gorges. Besides, a new zircon SHRIMP U-Pb age (614.0±7.6 Ma) is first obtained from a horizon underneath the exposed surface in the middle of the Doushantuo Formation in the Zhangcunping area. This age not only provides a new datum for subdivision of the Ediacaran Doushantuo Formation, but also indicates that the age of the exposed surface in the middle of the Doushantuo Formation in the Yangtze Platform should be posterior to 614.0±7.6 Ma. Due to the horizon of the Weng'an biota situated above the exposed surface, the age of the Wang'an biota should be posterior to 614.0±7.6 Ma as well.

    Add regions of the wodd occupy up to 35% of the earth's surface, the basis of various definitions of climatic conditions,vegetation types or potential for food production. Due to their high ecological value, monitoring of add regions is necessary and modem vegetation studies can help in the conservation and management of these areas. The use of remote sensing for mapping of desert vegetation is difficult due to mixing of the spectral reflectance of bright desert soils with the weak spectral response of sparse vegetation. We studied the vegetation types in the semiarid to arid region of Mond Protected Area, south-west Iran, based on unsupervised classification of the Spot XS bands and then produced updated maps.Sixteen map units covering t2 vegetation types were recognized in the area based on both field works and satellite mapping. Halocnemum strobilaceum and Suaeda fruticosa vegetation types were the dominant types and Ephedra foliata,Salicornia europaaa-Suaeda heterophylla vegetation types were the smallest. Vegetation coverage decreased sharply with the increase in salinity towards the coastal areas of the Persian Gulf. The highest vegetation coverage belonged to the riparian vegetation along the Mond River, which represents the northern boundary of the protected area. The location of vegetation types was studied on the separate soil and habitat diversity maps of the study area, which helped in final refinements of the vegetation map produced.

    There existed intense Cu anomaly on the northeastern side of the geochemical boundary with NW strike in the border area between the Yunnan and Guizhou provinces. Through field observation, ore bodies of high-grade native coppers have been found. The copper mineralization was constrained by the ancient volcanic vents of Permian basalt eruption and the overlain strata of carbonaceous argillites. Native coppers with flaky, net veined and impregnated occurrences, fine-grained tenorites and massive chalcocites widely occur in volcanic breccias, tuffs, carbonaceous-siliceous argillites and siliceous bitumen rocks with bed thickness of about 15-80 m. Cu contents vary from 0.5% to 20%. The copper mineralization was tightly related to actinolite-tremolitization, zeolitization and bituminization and involved in extensive reduction environments. Continental flood basalts erupted in mantle plume environments usually have high Cu concentrations (~170 ×10-6 in the Emeishan basalts), which provided a copper source of mineralization. Thus, metallogenesis of the native copper deposits in the Yunnan-Guizhou border area is tightly associated with intensive crust-mantle and organic-inorganic interactions. The tremolitization and chalcocitization indicate that the metallogenic temperatures are in a range of 400-100℃. The geologic background and characteristics of ore and alteration for the native copper deposits in this area are somewhat similar to those of the Keweenawan native copper deposit in Michigan, USA.

  18. Distribution and source of heavy metals in the surface sediments from the near-shore area, north Jiangsu Province, China

    International Nuclear Information System (INIS)

    Highlights: • The sediment source controls the distribution of the heavy metals. • There is no Cu, Pb, Zn and As pollution instead of slight Cd pollution. • Cu, Pb and Zn are lithogenic while Cd and As are mixed in origin. • Cd in polluted stations showed obvious anthropogenic origin. - Abstract: Samples of surface sediment and vibrocore were collected in the near-shore area of north Jiangsu Province for grain size, elements, 210Pbexcess and 137Cs analyses. In our study area, the diversity of metal concentration was controlled not by the grain size, but by the source. The element content of the old Yellow River Delta was used as baseline for our study area. Geoaccumulation indexes indicate that no station was polluted by Cu, Pb, Zn and As, but the Igeo values of As were close to zero in some stations. Slight pollution caused by Cd was observed in some stations. Correlation and enrichment factors suggest that Cu, Pb and Zn are lithogenic in origin, while As and Cd are mixed in origin. Especially, in some polluted stations Cd was obviously anthropogenic in origin

    2000-01-01

    We have collected a suite of Paleoloxodon naumanni-Coelodonta antiquitatis fossils from a river terrace profile between Xi'an and Xianyang cities in Guanzhong Area, Shaanxi Province. A detailed examination of the fossils, together with 14C determinations and pollen analyses, have enabled us to reconstruct preliminary features of climate and environment changes and their evolutionary processes, within the last glacial maximum (LGM): about 20 ka ago, the climate was basically cool and wet, and was favourable for the existence of Paleoloxodon naumanni-Coelodonta antiquitatis fauna. This was followed by a cold, dry phase which was no longer suitable for this type of faunal suite, causing the death of a large number of mammalian assemblages. The available evidence indicates the existence of cold-dry and cool-wet climate and environment fluctuations during the LGM. The cool-wet stage within the LGM reflects a Heinrich event occurring in the high latitude areas, proving the existence of a teleconnection between polar-high latitude areas and the Loess Plateau.

    Shot hole disease of stone fruit trees caused by some plant pathogenic fungi is a major constraint to stone fruit production worldwide where the trees are grown. Identification of the causal agents of the disease and their overwintering forms in stone fruit trees of Khorasan Razavi was necessary for disease management programs. Buds, twigs, fallen leaves and fruits were collected from the infected peach, apricot, nectarine and almond trees in winter 2007. The samples were superficially disinfested in 1% sodium hypochlorite for 2-3 min and then in 70% ethanol for 45 sec. Two to three fragments of 4x4 mm from each tissue were separately cultured on 2% water agar and potato dextrose agar (PDA), and purified on PDA. Just a pathogenic fungal species, Wilsonomyces corpophilus was isolated from the infected buds and twigs. No microorganism was isolated from the fallen leaves and fruits collected from underneath of the infested stone fruit trees. Pathogenicity of the fungus was examined on detached shoots of current year of four varieties of stone fruit trees. Fungal discs were placed under the bark of the bud base. Control shoots were similarly treated with sterile PDA discs. Inoculated shoots were placed in a humid growth chamber at 25 degrees C. Fungal hyphae appeared at 30 days post inoculation. Control shoots were asymptomatic. Pathogenicity intensities or lesion lengths were significantly different among the four varieties tested. A completely randomised design with five replicates was employed to measure the number of spores in infested buds and twigs of each variety of stone fruit tree. The samples were sliced and placed into a glass tube of centrifuge containing 3 ml of sterile distilled water. They were mixed on a vortex mixer for 30-40 min and centrifuged at 3000 rpm for 5 min. Pelleted material from each sample was suspended in 500 microl of sterile distilled water and the spores were counted using a hemocytometre. Results revealed that the fungus overwinters

    The toxicity of methylmercury (Me-Hg) has caused widespread public human concern as a result of several widely publicized disasters. Me-Hg is highly toxic, and the nervous system is its principal target tissue for humans. Although the general population is primarily exposed to Me-Hg through contaminated fish and marine mammals, in Hg mining areas a long history of mining activities can produce serious Hg pollution to the local environment In a study of 98 persons from the Wanshan Hg mining area, hair Me-Hg levels indicated Me-Hg exposure. Rice, the staple food of the local inhabitants also showed high total Hg (T-Hg) and Me-Hg levels. The geometric mean concentration of T-Hg and mean concentration of Me-Hg in rice samples collected from 3 villages in Wanshan Hg mining area were 36.2 (ranging from 4.9 to 214.7), and 8.5 (ranging from 1.9 to 27.6) microg/kg, respectively, which were significantly elevated compared to the rice samples collected from a reference area, where the mean T-Hg and Me-Hg concentrations were 7.0 (3.2-15.1) and 2.5 (0.8-4.3) microg/kg, respectively. Pork meat, vegetable, and drinking water samples collected in Wanshan Hg mining area contained highly elevated T-Hg, but very low levels of Me-Hg. The relationships between the estimated rice Me-Hg intake and hair Me-Hg levels (r = 0.65, p levels indeed was the main route of Me-Hg exposure for the local residents in the Wanshan Hg mining area. From our study, we can conclude that the main human exposure to Me-Hg via food consumption is not restricted to fish, but in some cases in mining areas of China to frequent rice meals.

    Full Text Available Groundwaters hydrochemistry of Ayrakan and Cheshmeh Shotori areas and geochemistry of rare earth elements, indicate Ayrakan alkali granite as the origin of uranium and other dissolved elements in groundwaters of these areas. Geochemical and hydrogeochemical studies as well as the trend of uranium and thorium transition and mobility in aqueous environments of these areas indicate uranium adsorption by iron hydroxide (goethite as the deterrent agent against uranium transition and mobility from depth to surface. Gamma-ray spectroscopic study of sediments from Cheshmeh Shotori area by HPGe detector indicates the presence of 226Ra in high contents and as the radioactive nuclide that is the reason for high activity of these sediments. Production of 226Ra from 238U decay, shorter half-life of 226Ra compared to 238U, radium transition by groundwaters from depth to surface as well as hydrogeochemical evidences, all suggest the possibility of existence of hidden uranium deposit and uranium mineralization in depth and the distance between Ayrakan and Cheshmeh Shotori areas.

    Vanadium is a trace element, which may be biologically beneficial and possibly essential but certainly harmful to human beings and some living organisms if excessive. After over 40 years of development, the mining industry has caused serious environmental problems in the Panzhihua mining area. Vanadium is significantly accu-mulated in the soil of the Panzhihua area. Human activities have intensified the pollution and release of vanadium and caused serious damages to the ecological system there. In the past few years, the authors have made investiga-tions into and assessments on the geochemical distribution, chemical speciation, adsorption characteristics and transfer behavior of vanadium in the topsoil in the Panzhihua mining area. The results showed that: (1) the difference in the contents of vanadium in soil between premonsoon and monsoon is insignificant; (2) the adsorption isotherms of vanadium on soil in the Panzhihua mining area ate well described by the Langmuir type; (3) the transfer ability of vanadium in soil is interrelated to soil properties; and (4) the chemical speciation of vanadium shows an order of insoluble residue > oxidizable=reducible > soluble component. According to the above results, some countermea-sures to control pollution of vanadium in soil should be put forward.

    On the basis of introducing relevant theories of Engel’s coefficient,this paper analyzes the limitation of these theories in practical application currently in China,for example,continuing to use original theory,not in line with reality of China;comparison invalidity in length and breadth,is not conducive to relevant analysis;culling out the special factors easily causes distortion of conclusion.Taking rural areas in Hebei Province as an example,this paper analyzes the limitation of Engel’s coefficient in analyzing the gap of rural economy:in terms of region horizontally,Engel’s coefficient neglects the difference of consumption structure among regions,and difference of economic stages among regions;in terms of time vertically,Engel’s coefficient neglects the periodic change of consumption structure and the ratio change of different families in different periods.According to the reality of China’s rural areas,the correction model of Engel’s coefficient is established as follows.Firstly,Engel’s coefficient=Percentage of expenditure variation(food+ education+ medical service) /Percentage of total expenditure variation;Engel’s coefficient=Percentage of expenditure variation(food+ education+ medical service) /Percentage of income variation.Secondly,Engel’s coefficient=Percentage of expenditure variation of food/Percentage of variation of(total expenditure educational expenditure-medical expenditure.Thirdly,Engel’s coefficient=Percentage of expenditure variation of food/Percentage of total expenditure variation.

    SummaryThis paper deals with a systematic hydrochemical study carried out at proximity basalt and granite areas of Deccan Volcanic Province (DVP) in India to assess groundwater quality and evaluate the hydrochemical processes. A total of 40 groundwater samples were collected equally from these areas and analyzed. Results showed that the groundwaters rich in alkaline earth in the basalt and alkali rich element in the granite. The dominancy of cations was observed as Ca2+ > Mg2+ > Na+ > K+ in the basalt and Na+ > Mg2+ > K+ > Ca2+ in the granite, whereas anions as HCO3->Cl>SO42- and Cl>HCO3->SO42-, respectively. Hydrochemical processes were identified with the helps of ion exchange, carbonate weathering and dissolution, multiple ionic ratios, and silicate weathering, which shown the predominance of carbonate, dolomite, calcite and silicate (anorthite) weathering in basalt, but in granite, silicate (alkali feldspar) weathering was dominated. Factor analysis also showed that there were multiple processes acting on groundwaters, were separated from the main cluster. Salinity, Sodium Absorption Ratio (SAR), Soluble Sodium Percentage (SSP), Residual Sodium Carbonate (RSC), Kelley's Ratio (KR) and Permeability Index (PI) in well samples showed that groundwater in basalt was more suitable for irrigation purposes. Further, a digital elevation model (DEM) was generated using Global mapper (8.0 version) software, which aided to decipher the thickness of basalt trap, and vertical transition zone of basaltic (trap) and granitic (basement) aquifer at this DVP comprising with the well depths and groundwater chemistry.

    Contents of lead in several crops as well as its uptake and distribution by paddy in typical lead-zinc deposit area of western Hunan province were studied based on field systematic sampling and laboratory analysis. The average concentration of lead in rice, maize and soy bean in the deposit was 2.4, 1.2 and 3.3 times higher than that in control area, respectively, suggesting that crops in the deposit were heavily contaminated by the element. Significant difference of the lead concentrations in crops was found among different crop species and different organs of the same crops. The average concentration of lead followed the trend: soy bean > rice > maize (among crop species), and root > haulm > seed (among organs). Paddy root exhibited strong binding and tolerant capacity to lead. Correlation analysis indicated that soil lead was main retention in paddy root, whereas the gaseous lead might be the main source for lead in the aerial part of crop. Heavy metals such as Hg, Cd as well as Pb co-enriched in crops, therefore the mechanism and health risk of the combined pollution of heavy metals in the deposit crops should be paid attention to.

    Picea likiangensis (Franch. ) Pritz. primary forest is one of the dominant forest types in the Small Zhongdian area in Shangri-La County of Yunnan Province. In this paper, the responses of P. likiangensis tree-ring width to climate change were analyzed by dendrochronological methods, and the dendrochronology was built by using relatively conservative detrending negative exponential curves or linear regression. Correlation analysis and response function analysis were applied to explore the relationships between the residual chronology series (RES) and climatic factors at different time scales, and pointer year analysis was used to explain the reasons of producing narrow and wide rings. In the study area, the radial growth of P. likiangensis and the increasing air temperature from 1990 to 2008 had definite 'abruption'. The temperature and precipitation in previous year growth season were the main factors limiting the present year radial growth, and especially, the temperature in previous July played a negative feedback role in the radial growth, while the sufficient precipitation in previous July promoted the radial growth. The differences in the temperature variation and precipitation variation in previous year were the main reasons for the formation of narrow and wide rings. P. likiangensis radial growth was not sensitive to the variation of PDSI.

    Full Text Available Introduction The Ramand area, southwest of Buin- Zahra, about 60 kilometers from Qazvin, lies in the igneous belt of the Urmieh-Dokhtar region, the main structural zone of north-central Iran. Rhyodacite and rhyolite lava flows are the principal host rocks of mineralization and alteration of the area, most of which occurs in faulted and brecciated zones alongmaj or northwest-trending fault systems (such as Kour-Cheshmeh, Hassan Abad and their branches. Clay minerals determined from satellite images indicated principally argillic hydrothermal alteration before laboratory mineralogical analysis. According to instrumental analyses, mineralized alteration with greater amounts of argillic halos and lesser amounts of sericitic-propylitic minerals contains quartz veinlets in the vertical and lateral sections. Initially, alteration in the Ramand area was revealed in ETM images by using the SPCA technique of Crosta and Moore, 1990 (Selective Principle Component Analysis. Compared with other techniques, SPCA results have reliable spectral signatures for identifying argillic minerals and Fe-oxides as the main mineralogical association in hydrothermal environments. Subsequently, multispectral images (ASTER were analyzed using band ratios.The results indicated silicification alteration along the faulted regions in the Ramand area. Later, areas of silicification alteration were prospected for precious and base metal mineralization.Sampling results suggested that the altered areas have some potential for epithermal mineralization, according to instrumental analyses and micrographic evidence. Materials and methods 1- Collecting satellite images, geological evidence and related documents 2- Image processing to reveal and identify the mineralized alteration. 3- Sampling of the mineralized zones indicated by the remote sensing. 4- Thin- and polished section microscopic studies. 5- X-ray diffraction analysis (XRD (19 samples, inductively coupled plasma mass

    2007-01-01

    By comparing micromorphological features of irrigated and non-irrigated soils in Guanzhong areas, China, this paper tries to illustrate the influences of farming management methods on the soil-forming process. The micromorphology was observed under a petrographic microscope and its image was quantificationally measured by Nikon NISBR 2.2 software.Both irrigated and non-irrigated soils have the same soil profile pattern, AP1-Ap2- BC, but the former has a more obvious profile dissimilation. The minerals assemblage of soil profiles A and B are very similar, which is mainly composed of Q and Pl. Compared with non-irrigated soil, grains of irrigated soil remarkably decrease in length, area, eqdiameter, perimeter,elongation, roundness, and C/F10 μm ratio; voids are characterized by more regular void shape and more smooth void wall;there is more abundant residual clay and small amount of illuvial clay. All results in this study suggest that the farming management method has influences on soil profile dissimilation and micromorphology. Agricultural irrigation could strengthen the degree of weathering, make smaller and rounder soil grains, cause a significant increase of residual clay and appearance of illuvial clay. But no significant change has been observed in the minerals assemblage of coarse grains.

    The use of high As-bearing coals has caused more than 3,000 cases of arsenosis patients in southwest Guizhou Province, China. The mode of occurrence of arsenic in coal is an important key role in understanding its behavior during usage and damage pathway to human health. Coal samples from endemic arsenosis areas were analyzed with INAA, EMPA, SEM-EDX, LTA, XRD, XAFS, and sequential leaching experiment. Arsenic in pyrite is from under the limit of EMPA to 1.75%, and in most cases, the content of arsenic is lower than 0.5%. Besides pyrite and arsenopyrite, SEM-EDX combined with LTA and XRD find that sulfates, clay and phosphates also contain arsenic. XAFS shows that arsenic mainly exists in the form of As5+. More than 50% of arsenic stayes in residual solid and combined with organic matrix in two samples, but most arsenic is leached out in other samples. The occurrence of such exceptionally high As contents in coal and the fact that the arsenic is dominantly organically associated are unique observations.

    2012-06-01

    A method is described for the generation of multivariate stochastic climate sequences for the Berg and Breede Water Management Areas in the Western Cape province of South Africa. The sequences, based on joint modeling of precipitation and minimum and maximum daily temperatures, are conditioned on annualized data, the aim being to simulate realistic variability on annual to decadal time scales. A vector autoregressive (VAR) model is utilized for this purpose and reproduces well those statistical attributes, including intervariable correlation and serial autocorrelation in individual variables, most relevant for the regional climate in this setting. The sequences incorporate nonlinear climate change trends, inferred using an ensemble of global climate models from the Coupled Model Intercomparison Project (CMIP5). Subannual variability is simulated using a block resampling scheme based on the k-nearest-neighbor approach, preserving both temporal patterns and spatial correlations. Downscaling to a network of quinary-level catchments enables distributed runoff, streamflow, and crop simulations and the assessment and integration of impacts. Final output takes the form of daily sequences, structured for driving the ACRU agrohydrological model of the University of KwaZulu-Natal, South Africa.

    In response to a hemorrhagic fever with renal syndrome case in November 2000, a seasonal rodent-borne disease surveillance program was initiated at Dagmar North Training Area (DNTA), Gyeonggi Province, Republic of Korea. From April 2001-December 2005, 1,848 small mammals were captured. Apodemus agrarius accounted for 92.5%, followed by Mus musculus (3.6%), Crocidura lasiura (2.1%), and Microtus fortis (1.1%). Three species of rodents were found to be antibody-positive (Ab+) for Hantaan virus (HTNV): A. agrarius (22.3%), M. musculus (9.1%), and M. fortis (5.0%). Ab+ rates for A. agrarius increased with increasing weight (age), except for those weighing <10 g. The peak HTNV transmission period in Korea coincided with the peak reproductive potential of A. agrarius during the fall (August/September) surveys. HTNV strains from DNTA were distinct from HTNV strains from the People's Republic of China. From these studies, more accurate risk assessments can be developed to better protect personnel from rodent-borne diseases.

    2009-11-01

    Full Text Available The Gunungsewu area is a karst terrain with water scarcity, located in the Yogyakarta Special Province, adjacent to the open sea of Indian Ocean in the South. Shorelines of the Gunungsewu southern parts show fractal geometry phenomenon, and there can be found some groundwater outlets discharging to the Indian Ocean. One of the coastal outlets exists at the Baron Beach.The amount of water discharge from this spring reaches 20,000 l/sec in wet season, and approximately 9000 in dry season. In order to find other potential coastal springs, shoreline of the south coast is divided into some segments. By applying fractal analysis utilizing air photo of 1 : 30,000 scale, the fractal dimension of every shore line segment is determined, and then the fractal dimension value is correlated to the existence of spring in the segment being analyzed. The results inform us that shoreline segments having fractal dimension (D > 1.300 are potential for the occurrence of coastal springs.

    2014-06-01

    Full Text Available DOI: 10.17014/ijog.v7i3.142The carbonate sequence overlies conformably the tuffaceous sandstone unit, and in turn is conformably underlain by the tuff-sandstone unit, both of which are members of the Citarate Formation. The Citarate carbonate rocks were deposited in an open platform back reef environment, which was temporarily drowned by local sea level rise. Regional Middle Miocene deformation formed NNE-WSW trend faults and E-W trend folds in the researched area. This paper discusses the nature of diagenetic alteration of the Citarate carbonate rocks based on petrographic analyses of twenty surface samples. Carbonate rocks from bottom to top comprise algae packstone, packstone-grainstone, coral-algae packstone, and foraminifer wackestone-packstone. Fragments of coral, coralline red algae, and large foraminifera are the dominant bioclasts in most of the observed samples, whereas echinoids and bivalves are less abundant; they are set in a recrystallized micrite matrix. Planktonic foraminifera are abundant only in few samples. Fragments of plagioclase, igneous volcanic rocks, pyroclastic rocks (tuff, and much less abundant quartz are commonly present in all the studied samples. A generalized diagenesis includes early marine cementation by fibrous aragonite, compaction, aragonite dissolution and/or neomorphism, precipitation of equant-grained calcite cement in a phreatic environment, dissolution to form moldic porosities, dolomitization, the formation of stylolites and fractures, and precipitation of late ferroan calcite during burial. Multiple carbonate cements occur as pore-filling phases, with ferroan calcite cementation taking place during later-stage burial. Secondary porosities were formed during different stages in diagenetic processes, such as dissolution, dolomitization, and stylolite and fracture formations. Although precipitation of nonferroan and ferroan calcite cement occluded porosities, porosity enhancement during early selective

    Southwest Guizhou Province is one of the most important areas of disseminated, sediment-hosted-type Au deposits in China and is an important area of coal production. The chemistry of most of the coals in SW Guizhou is similar to those in other parts of China. Their As content is near the Chinese coal average, but some local, small coal mines contain high As coals. The highest As content is up to 3.5 wt.% in the coal. The use of high As coals has caused in excess of 3000 cases of As poisoning in several villages. The high As coals are in the Longtan formation, which is an alternating marine facies and terrestrial facies. The coals are distributed on both sides of faults that parallel the regional anticlinal axis. The As content of coal is higher closer to the fault plane. The As content of coal changes greatly in different coal beds and different locations of the same bed. Geological structures such as anticlines, faults and sedimentary strata control the distribution of high As coals. Small Au deposits as well as Sb, Hg, and Th mineralization, are found near the high As coals. Although some As-bearing minerals such as pyrite, arsenopyrite, realgar (?), As-bearing sulfate, As-bearing clays, and phosphate are found in the high As coals, their contents cannot account for the abundance of As in some coals. Analysis of the coal indicates that As mainly exists in the form of As5+ and As3+, perhaps, combined with organic compounds. The occurrence of such exceptionally high As contents in coal and the fact that the As is dominantly organically associated are unique observations. ?? 201 Elsevier Science Ltd.

  14. Use of attractant traps in area-wide control of vegetable insect pests in the Jiangxi province of China

    International Nuclear Information System (INIS)

    Full text: Plutella xylostella (L.), Prodenia litura (Fabricius) and Laphyqma exiqua Huebner are main insect pests of vegetables in the Jiangxi province. The long-term use of pesticides to control these pests has caused serious problems such as resistance to pesticides and resurgence of pests as well as pollution to environment and vegetables. Sex attractants have been used for area-wide control of these pests to solve these problems and to produce pollution-free vegetables. Based on the principles of effective, economic and operational implementation, two types of traps made of used plastic cola bottles (1.25L) and oil bottles (2.5L), have been used in 2,250 ha of vegetables in 2001-2003. Traps have been baited with pest-specific attractants incorporated in a rubber wick and placed in vegetable fields at a density of 45 traps per ha. The area-wide use of sex attractants to control these pests has resulted in the decrease of densities of male adults, eggs and larva of these pests and the increase of vegetable yield. An average of 2.34, 2.1, 2.85 male P. xylostella (L.), P. litura (Fabricius) and L. exiqua Huebner was trapped per day respectively with the cola bottle trap, and 3.22, 0.63, 4.33 male P. xylostella (L.), P. litura (Fabricius) and L. exiqua Huebner was trapped per day respectively oil bottle trap. Comparing trap area with non-trap area, egg density of P. xylostella (L.) on radish plants and cabbage plants was decreased by 84.48% and 85.38%, respectively and larva density of P. xylostella (L.) on radish plants and cabbage plants was decreased by 89.62% and 89.93%, respectively. The egg and larva density of L. exiqua Huebner was reduced by 66.67% and 64.47%, respectively and the percent of damaged host plants and leaves was reduced by 83.48% and 75.85%, respectively. The larva density of P. litura (Fabricius) was reduced by 24.92% and the percent of damaged host plants was reduced by 35.52%. The vegetable yield per ha has been increased by 30% on average

    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.

    Hunan province, Central South China, is a well-known nonferrous metal base in China. Mine exploiting and processing there, however, often lead to heavy metal pollution of farmland. To study the effects of mining activities on the soil environmental quality, four representative paddy fields, the HSG, SNJ, NT and THJ, in Y county, northern Hunan province, were investigated. It was found that the streams running through the HSG, SNJ and NT are severely contaminated due to the long-term discharge of untreated mineral wastewater from local indigenous mining factories. The stream at the HSG, for example, is brownish red in color, with high concentrations of Cu, Zn, Cd, Fe and Mn. The concentrations of Cu, Zn and Cd in all the stream water of the HSG, SNJ and NT exceed the maximum allowable levels of the Agricultural Irrigation Water Criteria of China. Correspondingly, the HSG, SNJ and NT are heavily polluted by Cu, Zn and Cd due to the long-term irrigation with the contaminated stream water. In comparison, both stream water and paddy fields of the THJ, far away from mining areas, are not contaminated by any heavy metals and hence regarded as a control in this study. The rice grain produced at the HSG, SNJ and NT has a high risk of Cd contamination. The rate of rice grain produced in the four paddy fields in Y county with Cd exceeding the safe level (Cd, 0.2 μg g-1) specified by the National Standards for Rice Quality and Safety of China reaches 90%. Cd content in the rice grain is positively significantly correlated with that in the paddy fields, especially with the content of diethylenetriaminepentaacetic acid (DTPA) - extracted Cd, suggesting that the heavy metal pollution of paddy fields has already posed a high risk to rice safety and human health. Soil enzyme activities and microbial biomass are significantly inhibited by the heavy metal pollution of the paddy fields. Microbial biomass C and N (MBC and MBN) at a severely contaminated site of the HSG are only 31

    The well-preserved seamount buildups are documented from the northwestern Qinling (秦岭) orogenic belts, Northwest China. The study sections are located in the Ganjia (甘加) area of the Xiahe (夏河) County, Gansu (甘肃) Province. The dark basalt and overlying massive reef carbonate characterize the Xiahe seamount buildup. Basalts are dominated by the olivine type of rocks and bear distinct porphyritic textures, and fumarole and amygdaloidal structures. The basaits are dominated by SiO2(up to 48.49 wt.%-52.29 wt.%) followed by (Na2O+ K2O) (3.80 wt.%-4.96 wt.%) and TiO2 (2.04 wt.%-2.52 wt.%). They are featured by considerably high content of Ti. The tholeilteseries rocks dominate the basalts, while calc-alkali-series rocks are also present. The REE of the basalts shows the LREE-enrichment type with distinct positive Eu abnormal. The trace elements of the basalts are characterized by the lack of P and high content of Ti. These geochemical signals suggest that the Xiahe basalts were formed in an ocean-island setting. The LA ICP-MS zircon U-Pb age of the basalts is 267.6±5 Ma, which is reinforced by the presnce of the fusuHnid Neoschwagerina Zone of the Wordian (Middle Permian) in the limestone interbeds of the basalts. Integration of petrological and geochemical studies of seamount basaits and lateral correlation of seamount buildups reveals that the Qinling-qilian-Kunlun orogenic belts were probably the archipelagtc oceans during the Permian.

    Three outcrops of the Libertad and Sauces Formations from the Los Sauces area La Rioja Province, western Argentina, yielded the nine palynoassemblages studied here. Two assemblage zones are defined on the basis of the stratigraphic distribution and ranges of seventy five species of palynomorphs (42 species of spores, 32 pollen taxa and one fungus). Only thirteen species are common to both assemblages and ten species are first records for the Paganzo Basin. Assemblage 1 from the Libertad Formation is dominated by trilete spores of Cristatisporites (lycophyte) and Punctatisporites (pteridophyte). Monosaccate pollen (Coniferales/Cordaitales) is frequently present. Pteridosperms, mostly represented by Cyclogranisporites, are especially abundant in one level together with scarce striate bisaccate pollen grains. Assemblage 2 of the Sauces Formation is dominated by trilete spores related to the Pteridophyta (e.g., Horriditriletes, Converrucosisporites, Granulatisporites) and Sphenophyta. Monosaccate (Cordaitales/Coniferales) and taeniate and non-taeniate bisaccate pollen grains (Pteridospermales/Coniferales), are equally subordinated. Monosulcate pollen (Cycadophyta) and fungi (Portalites gondwanensis) are rare. Assemblage 1 is mainly Moscovian; assemblage 2 Asselian-Sakmarian. This interpretation is based on correlation of assemblage 1 to the DMb (Mid Pennsylvanian) and assemblage 2 to the FS (Early Cisuralian) Biozones of the Paganzo Basin (Argentina). The taxonomic composition of the Ahrensisporites cristatus-Crucisaccites monoletus (Mid-Late Pennsylvanian) and the Protohaploxypinus goraiensis Subzone (Asselian-Sakmarian) of the Vittatina costabilis (Early Cisuralian) Biozones of the Parana Basin (Brazil) support this correlation. The continental freshwater depositional setting of this part of the Paganzo Basin is supported by the dominance of terrestrial palynomorphs and phytoclasts, the presence of coal and carbonaceous shales, and the occurrence of plant megafossils

    Rice paddy plantation is the dominant agricultural land use throughout Asia. Rice paddy fields have been identified as important sites for methylmercury (MeHg) production in the terrestrial ecosystem and a primary pathway of MeHg exposure to humans in mercury (Hg) mining areas. We compared the source and distribution of Hg species in different compartments of the rice paddy during a complete rice-growing season at two different typical Hg-contaminated mining sites in Guizhou province, China: an abandoned site with a high Hg concentration in soil but a low concentration in the atmosphere and a current-day artisanal site with a low concentration in soil but a high concentration in the atmosphere. Our results showed that the flux of new Hg to the ecosystem from irrigation and atmospheric deposition was insignificant relative to the pool of old Hg in soil; the dominant source of MeHg to paddy soil is in situ methylation of inorganic Hg (IHg). Elevated MeHg concentrations and the high proportion of Hg as MeHg in paddy water and the surface soil layer at the artisanal site demonstrated active Hg methylation at this site only. We propose that the in situ production of MeHg in paddy water and surface soil is dependent on elevated Hg in the atmosphere and the consequential deposition of new Hg into a low-pH anoxic geochemical system. The absence of depth-dependent variability in the MeHg concentration in soil cores collected from the abandoned Hg mining site, consistent with the low concentration of Hg in the atmosphere and high pH of the paddy water and irrigation water, suggested that net production of MeHg at this site was limited. We propose that the concentration of Hg in ambient air is an indicator for the risk of MeHg accumulation in paddy rice.

    Full Text Available Background: To differentiate Sarcocystis macro-cyst-forming species in slaughtered sheep in Babol area, Mazandaran Province, sequence analysis of 18S rRNA gene was performed.Methods: Overall, 150 slaughtered sheep were examined macroscopically in slaughterhouse, Babol and intra-abdominal and diaphragm muscles tissues infected with macro-cyst of Sarcocystis spp. were collected in 2013. One macro-cyst was isolated from the infected muscles of each sheep. The partial 18S rRNA gene was amplified by PCR and sequenced afterward.Results: The rate of infection with macro-cyst producing Sarcocystis spp. was 33.3% (50 / 150. The partial 18S rRNA gene of Sarcocystis species was amplified at the expected PCR product size (~1100 bp from all 50 macroscopic cysts samples. From 30 sequences DNA samples, 20 samples (66.7%, six (20% and four (13.3% isolates were identified as S. gigantea, S. moulei and Sarcocystis spp., respectively. Eight and thirty-four variations in nucleotide position were seen in partial sequence of the18S rRNA gene of S. gigantea and S. moulei.Conclusion: Sheep can be considered as an alternative intermediate host for S. moulei. Furthermore, multiple alignments showed some variations in the consensus sequences of the isolates obtained in the current study compared with previously published isolates. To understand better the genetic diversity among Sarcocystis species complete sequences of the18S rRNA gene or sequence analysis of other genetic loci would be beneficial.

    According to the cultivated land ecological security in major grain production areas of Northeast China, this paper selected 48 counties of Jilin Province as the research object. Based on the PSR-EES conceptual framework model, an evaluation index system of cultivated land ecological security was built. By using the improved TOPSIS, Markov chains, GIS spatial analysis and obstacle degree models, the spatial-temporal pattern of cultivated land ecological security and the obstacle factors were analyzed from 1995 to 2011 in Jilin Province. The results indicated that, the composite index of cultivated land ecological security appeared in a rising trend in Jilin Province from 1995 to 2011, and the cultivated land ecological security level changed from being sensitive to being general. There was a pattern of 'Club Convergence' in cultivated land ecological security level in each county and the spatial discrepancy tended to become larger. The 'Polarization' trend of cultivated land ecological security level was obvious. The distributions of sensitive level and critical security level with ribbon patterns tended to be dispersed, the general security level and relative security levels concentrated, and the distributions of security level scattered. The unstable trend of cultivated land ecological security level was more and more obvious. The main obstacle factors that affected the cultivated land ecological security level in Jilin Province were rural net income per capita, economic density, the proportion of environmental protection investment in GDP, degree of machinery cultivation and the comprehensive utilization rate of industrial solid wastes.

    Zircon U-Pb ages and geochemical analytical results are presented for the volcanic rocks of the Naozhigou, Ergulazi, and Sidaogou Formations in the Linjiang area, southeastern Jilin Province to constrain the nature of magma source and their tectonic settings. The Naozhigou Formation is composed mainly of andesite and rhyolite and its weighted mean 206Pb/238U age for 13 zircon grains is 2224±1 Ma. The Ergulazi Formation consists of basaltic andesite, basaltic trachyandesite, and andesite, and six grains give a weighted mean 206Pb/238U age of 131±4 Ma. The Sidaogou Formation consists mainly of trachyandesite and rhyolite, and six zircon grains yield a weighted mean 206Pb/238U age of113±4 Ma. The volcanic rocks have SiO2=60.24%-77.46%, MgO=0.36%-1.29% (Mg#=0.32-0.40) for the Naozhigou Formation, SiO2=51.60%-59.32 %, MgO=3.70 %-5.54% (Mg#=0.50-0.60) for the Ergulazi Formation, and SiO2=58.28%-76.32%, MgO=0.07%-1.20% (Mg#=0.14-0.46) for the Sidaogou Formation. The trace element analytical results indicate that these volcanic rocks are characterized by enrichment in light rare earth elements (LREEs) and large ion lithophile elements (LILEs), relative depletion in heavy rare earth elements (HREEs) and high field strength elements (HFSEs, Nb, Ta, and Ti), and negative Eu anomalies. Compared with the primitive mantle, the Mesozoic volcanic rocks in the Linjiang area have relatively high initial 87Sr/86Sr ratios (0.7053-0.7083) and low eNd(t) values (-8.38 to -2.43), and display an EMII trend. The late Triassic magma for the Naozhigou Formation could be derived from partial melting of a newly accretional crust with the minor involvement of the North China Craton basement and formed under an extensional environment after the collision of the Yangtze Craton and the North China Craton. The Early Cretaceous volcanic rocks for the Ergulazi and Sidaogou Formations could be formed under the tectonic setting of an active continental margin related to the westward snbduction of

    Urbanization is one of the driving forces for the land use change in type and structure, and its prominent effect is to convert rural land to urban land. This paper takes Shandong Province as an example to analyze the current situation of the mutual conversion between the urban and rural areas from the aspects of the structure of land use, the decreasing tendency of the cultivated land, the changes of land use in urban and rural residential areas. It points out that cultivated land is converted to residential area land, industrial and/or mining area land. The relationship between the urban area land and the cultivated land is more direct; meanwhile, the changes of rural residential area lag behind obviously. The decrease of the cultivated land and the decline of soil quality will be the two difficult problems in the process of urbanization.

    Full Text Available Introduction The Fanuj titaniferous placer deposits are located 35 km northwest of the Fanuj, Sistan and Baluchestan province (1 . The studied area comprises a (2 small part of the late Cretaceous Fanuj-Maskutan (Rameshk ophiolite complex (Arshadi and Mahdavi, 1987. Reconnaissance and comprehensive exploration programs in the Fanuj district (East of the 1:100000 Fanuj quadrangle map,Yazdi, 2010 revealed that the Upper Jogaz Valley area has the highest concentration of titaniferous placer deposits. In this study, geology and formation of the titaniferous placer deposits in Upper Jogaz Valley area are discussed. Materials and Methods (3 Forty samples were collected from surface and drainage sediments to evaluate the potential for titaniferous placers. Mineralogical studies indicated the high Ti (ilmenite bearing areas, which led to detailed exploration by 29 shallow drill holes and 9 trenches. A total of 61 sub-surface samples were collected for heavy mineral studies and ore grade determination. The exploration studies suggest that the the Upper Jogaz Valley area in the Fanuj district has a high potential for titaniferous placer deposits. Extensive exposures of black sands in the sreambeds of this area suggested detailed sampling, so that 12 holes were drilled (2-3 m depthfrom which 26 samples were collected, and five trenches were excavated to 2-4 m depth (4. The distribution of drill holes and trenches were plotted with “Logplot” software for further interpretation. Twenty-two samples from these drill holes were analyzed for TiO2. Results The reconnaissance and comprehensive exploration in Fanuj district shows that the Upper Jogaz Valley area has the highest concentration of titaniferous placer deposits. The general geology of the region and petrology and mineralogy of collected samples suggest that the source rock of the Upper Jogaz Valley titaniferous placers is the hornblende- and olivine-gabbro unit of the Fanuj-Ramesh ophiolites. The Ti

    Village-level economy is not only the important foundation for promoting grass-roots agricultural and rural modernization, but also an essential guarantee for sustainable development of small scale economy of rural farmer households. Research on this field will play a significant role in rural economic development of Guizhou Province. Taking the observation data from 1999 to 2009 in 10 fixed observation villages in Guizhou Province, we carried out empirical survey and analysis on land scale and use structure, scale and composition of fixed assets for production, level and composition of operational income, and level and composition of financial revenue and expenditure at village level. Finally, we put forward conclusions and recommendations.

  8. Geochronological Significance of the Post-Orogenic Mafic-Ultramafic Rocks in the Hongqiling Area of Jilin Province, Northeast China

    Mafic-ultramafic complexes are widespread in Hongqiling in central Jinlin Province, NE China. The Hongqiling complex comprises pyroxenite, olivine websterite, lherzolite, gabbro and leucogabbro. Based on the latest geochronological results, these intrusions yield a zircon U-Pb age of about 216 Ma, implying that they emplaced in the late Triassic period and that the mafic-ultramafic complexes are post-orogenic in origin. These ages are coeval with the emplacement of A-type granites in the area, but slightly younger than syn-orogenic granitic magmatism. The composition of the parent magma during the equilibration of the accumulated olivine crystallizing is basaltic with high MgO, and it comes from depleted or juvenile lithospheric mantle, according to the results of trace elements and Sr-Nd isotopes. Amount of crustal material contaminated the magmatic source, implying that the mafic-ultramafic rocks originate from the mixing product of crust- and mantle-derived magma. Therefore, the magmatic source was contaminated by an amount of crustal material, and the subsequent crystal fractionation resulted in the Cu-Ni mineralization. Dynamic analyses indicate that, after the collision of the North China Craton and Jiamusi Massif, the lithospheric delamination during post-orogeny resulted in the upwelling of asthenosphere and the intruding of the mass and underplating of the mantle-derived magma, which led to the formation of the primary mafic-ultramafic magma due to the mantle-derived magma and partial melting of the lower crust. This result suggests that the mafic-ultramafic complexes belong to a typically important magmatic suite that evolved during post-orogenic processes, and they were exposed as maficultramafic dyke swarms that existed in the post-orogenic extension environment. It also implies that the orogenic process finished ultimately in this regional geological setting. The widespread occurrence of mafic-ultramafic complexes in the Xing'an-Mongolia Orogenic Belt

    At present, China has achieved an initial establishment and gradual implementation of a framework for national essential drugs policy. With the further implementation of the national essential drugs policy, it is not clear how the policy works, whether it achieves the original intention of essential drugs policy, and what impact essential drugs policy exerts on the primary health care system. In view of it, we conducted a field research on sample areas of Shandong Province to understand the conditions of the implementation of the essential drugs policy in Shandong Province. From three perspectives of medical institutions, patients and medical staff, this thesis analyzes the impact of essential drugs policy on village-level and township-level health service system, summarizes the effectiveness of implementing essential drugs policy, discovers the problems of various aspects and conducts an in-depth analysis of the causes, and puts forward feasible suggestions to provide reference for improving the essential drugs policy. The assessment results show that the implementation of essential drugs policy in Shandong Province has played a positive role in promoting the sound development of the primary health care system, changed the situation of covering hospital expenses with medicine revenue in the past, contributed to the return of medical institutions to public welfare, and reduced the patient's economic burden of disease. But there emerge many problems as follows: impact on the doctor's diagnosis and treatment due to incompleteness of drug types, and distribution not in place, patient loss and operational difficulty of village clinic. Thus, this thesis makes recommendations of drugs catalog formulation, drug procurement, sales and use, and meanwhile points out that the supporting financial compensation policy and performance appraisal policy and other measures in place are a prerequisite for a positive role of essential drugs policy.

    The national data provided by ANMCO in 1978 show a total of 2.5 m heart cases in Italy, including 1.5 m instances of ischaemic cardiopathy, and an annual incidence of 105,000 new cases of myocardial infarct. An assessment was made of the 1976 and 1977 pattern of "cardiological emergency cases" (ISTAT codes 402, 410-14, 427-29, 441, 450, 519, 997) in the province of Florence and two of its social and health consortia: 39 (municipalities of Dicomano, Londa, Pelago, Pontassieve, Rufina, S. Godenzo), and 51 (municipalities of Borgata Ripoli, Greve, Impruneta, S. Casciano, Tavarnelle). The records of the S. Maria Nuova, Florence Hospital were used for in-patient data, since this is the only hospital in the province with automatic filing by discharge diagnosis according to the ISTAT code. Mortality in emergency cases in the two consortia m and the province fell from 14.68% and 17.17% to 11.20% and 18.11% respectively in the two years. In both populations, the highest incidence was between 70 and 74 yr of age in 1976, and between 65 and 69 yr in 1977. In the case of infarct, mortality moved from 18.75 to 7.58% (consortia) and from 22.40% to 20.93% (province), with maximum incidences in 1976 between 70 and 74 yr (consortia and province), and in 1977 between 65 and 69 yr (province) and between 55 and 59 yr (consortia). Admissions were greatest in number on Mondays (peak hours: 11 a.m. to 4 p.m.) whereas no difference was noted between one month and another. The Hospital Resuscitation Centre, which serves the two consortia, received 45 emergency cases in 1977, including 25 infarct patients. Total mortality was 13.33% (infarct 20%). The slight numeric discrepancy between in the latter data and those held in the computer suggests that the ISTAT code may not be easy to use and not always employed by physicians in a rational manner.

    Hyperspectral remote sensing is a frontier of remote sensing. Due to its advantage of integrated image with spectrum, it can realize objects identification, superior to objects classification of multispectral remote sensing. Taken the Mingshujing area in Gansu Province of China as an example, this study extracted the alteration minerals and thus to do metallogenic prediction using CASI/SASI airborne hyperspectral data. The Mingshujing area, located in Liuyuan region of Gansu Province, is dominated by middle Variscan granites and Indosinian granites, with well developed EW- and NE-trending faults. In July 2012, our project team obtained the CASI/SASI hyperspectral data of Liuyuan region by aerial flight. The CASI hyperspectral data have 32 bands and the SASI hyperspectral data have 88 bands, with spectral resolution of 15nm for both. The hyperspectral raw data were first preprocessed, including radiometric correction and geometric correction. We then conducted atmospheric correction using empirical line method based on synchronously measured ground spectra to obtain hyperspectral reflectance data. Spectral dimension of hyperspectral data was reduced by the minimum noise fraction transformation method, and then purity pixels were selected. After these steps, image endmember spectra were obtained. We used the endmember spectrum election method based on expert knowledge to analyze the image endmember spectra. Then, the mixture tuned matched filter (MTMF) mapping method was used to extract mineral information, including limonite, Al-rich sericite, Al-poor sericite and chlorite. Finally, the distribution of minerals in the Mingshujing area was mapped. According to the distribution of limonite and Al-rich sericite mapped by CASI/SASI hyperspectral data, we delineated five gold prospecting areas, and further conducted field verification in these areas. It is shown that there are significant gold mineralized anomalies in surface in the Baixianishan and Xitan prospecting

    Using the latest results of seismic tomography, we studied the deep tectonic settings of the moderate and strong earthquakes in Anhui Province and its neighboring areas (28°~ 39°N,112°~ 124°E). The results are as follows: (1) There exists a certain correlation between the location of moderate-strong earthquake, the geologic structure of the surface and the partitioning of active tectonic elements with the upper-crust velocity structure. Most earthquakes recording M ≥ 6.0 occur in high-velocity zones or in the transitional areas between high-velocity and low-velocity zones in the upper crust. Seismicity in the low-velocity zone has a lesser impact. Earthquakes occuring in the high-velocity zone are distributed mainly in the velocity variation area. The boundary belts and the interior of the North China plain fault block are the main active sites of moderate-strong earthquakes. Beneath the fault basins in the western and northern sides of the block, the upper crust is characterized by a wide discontinuous distribution in the low-velocity zone, and in the transition zone from the low- to higl velocities, the moderate strong seismicity shows a zonal distribution where active faults are developed. The NW-extension Zhoukou-Hefei-Xuancheng low-velocity zone separates the high-velocity zones of Dabieshan Mountains and west Shandong-Anhui, and moderate-strong earthquakes on its northern side bordering the high-velocity zones are relatively frequent. This low-velocity zone is probably an important and deeply structured boundary between the North China and the South China tectonic provinces. (2) The frequent moderate-strong earthquake recorded in the past and the recent small earthquake activities in the Huoshan-Lu' an area are the result of a low-velocity zone in the middle crust beneath the central part of Dabieshan and the two sets of deep faults that cut through the crust. (3) In terms of deep structures, the distribution of moderate-strong earthquake in Anhui

    Full Text Available Herbicides (atrazine, glyphosate and paraquat have been intensively used in Nan Province for a long time. Prior observations indicated that herbicide contamination and adverse health effects were found on the rice frog Fejervarya limnocharis living in paddy fields at Nan Province. Contamination of herbicides may influence disease emergence by acting directly or indirectly upon the immune system of amphibian or by causing disruptions in homeostasis, it is thus interesting to investigate potential effects of herbicide contamination in Nan Province on immune responses of the rice frog living in agricultural areas. Frogs were caught from a paddy field with no history of herbicide utilization (reference site and a paddy field with intensive herbicide utilization (contaminated site during 2010-2011. After dissection, frog livers were fixed in 10% neutral buffer formalin, processed by paraffin method and stained with hematoxylin and eosin. Number of melanomacrophage and melanomacrophage center (MMC were counted under a light microscope and used as markers of non-specific immune response. It was found that there was no significant sex-related difference in these numbers. However, there were significant seasonal differences in these numbers in both reference and contaminated site frogs, suggesting that seasonal difference in herbicide usage tend to affect frog's immune system in agricultural areas. Furthermore, numbers of melanomacrophage and MMC in early wet, late wet and early dry periods were markedly higher in the contaminated site frogs compared to those of the reference site frogs. The observation on amphibian's immune response to environmental contaminants could indicate the impacts of herbicide utilization on other vertebrates, as well as its role in amphibian declines.

    AIM: To study the main environmental and lifestyle factors that account for the regional differences in esophageal cancer (EC) risk in low- and high-risk areas of Jiangsu Province, China.METHODS: Since 2003, a population-based casecontrol study has been conducted simultaneously in lowrisk (Ganyu County) and high-risk (Dafeng County) areas of Jiangsu Province, China. Using identical protocols and pre-tested standardized questionnaire, following written informed consent, eligible subjects were inquired about their detail information on potential determinants of EC, including demographic information, socio-economic status, living conditions, disease history, family cancer history, smoking, alcohol drinking, dietary habits, frequency, amount of food intake, etc. Conditional logistic regression with maximum likelihood estimation was used to obtain Odds ratio (OR) and 95 % confidence interval (95% CI), after adjustment for potential confounders.RESULTS: In the preliminary analysis of the ongoing study, we recruited 291 pairs of cases and controls in Dafeng and 240 pairs of cases and controls in Ganyu,respectively. In both low-risk and high-risk areas, EC was inversely associated with socio-economic status, such as level of education, past economic status and body mass index. However, this disease was more frequent among those who had a family history of cancer or encountered misfortune in the past 10 years. EC was also more frequent among smokers, alcohol drinkers and fast eaters.Furthermore, there was a geographic variation of the associations between smoking, alcohol drinking and EC risk despite the similar prevalence of these risk factors in both low-risk and high-risk areas. The dose-response relationship of smoking and smoking related variables,such as age of the first smoking, duration and amount were apparent only in high-risk areas. On the contrary, a dose-response relationship on the effect of alcohol drinking on EC was observed only in low-risk areas

    In Lingyuan region of West Liaoning Province, the Zhangjiakou Formation (J3z) and the Yixian Formation (K1y) display an angular unconformity. That is, the Lower Mesozoic strata of the Zhangjiakou Formation are ENE (near E-W) oriented, while the overlying strata of the Yixian Formation exhibit an NNE orientation. The results of LA-ICP-MS zircon U-Pb ages show the Zhangjiakou Formation formed from about 130 Ma to 132 Ma in Lingyuan and 135 Ma to 136 Ma in Luanping (North Hebei Province), respectively. Three conclusions can be drawn: (1) The Zhangjiakou Formation in Lingyuan is comparable to that in Luanping, with the volcanic rocks of the Zhangjiakou Formation from Lingyuan being younger than those from Luanping. (2) 5-6 Ma difference between the top of the Zhangjiakou Formation and the bottom of the Yixian Formation in Lingyuan proves the angular unconformity between the two formations; and it reflects that the 5-6 Ma interval period is the main period of the transition of tectonic framework in Mesozoic in North Hebei and West Liaoning. In the interval period, the magmatic action went up to high tide in Mesozoic in the northeast of China. Moreover, after the interval period, the "Rehe fauna" developed into "erupted" period. This reflects that the interval period is also an important biological interface in Northern Hebei and Western Liaoning. (3) The Dabeigou Formation in Luanping should correspond to the upper part of the Zhangjiakou Formation, but not to the lower part of the Yixian Formation.

    Full Text Available The area is located 20 km northwest of Kashmar and about 4 km of Kalateh Taimour in Khorasan Razavi province. The study area is part of Tertiary volcanic-plutonic belt north of Daruneh fault and its situation in tectonic inliers between two important active faults, Doruneh and Taknar. Volcanic rocks are mainly intermediate to acid pyroclastic type. They formed during early Tertiary. The volcanic rocks of the Kalateh Taimour area are predominantly andesitic basalt, andesite, latite, trachyte, dacite and rhyodacite and are observed as lava, tuff, lapilli tuff and agglomerate. Field evidences and study show several subvolcanic bodies including quartz hornblende biotite monzodiorite porphyry, quartz biotite monzodiorite porphyry, quartz diorite porphyry and microdiorite which are intruded sometime in mid-Tertiary. In this belt, new methods of image processing were used for enhancing the alteration zones to help near infra red and short wavelength infrared and bands example band ratios and principle component method. Propylitic, sericitic and argillic are the main alteration types. Minor silicification is found in some areas. Alteration is extent but mineralization is limited. Mineralization is mainly controlled by fault system. Several mineralized faults are being discovered. Open space filling features are abundant. In the study area, disseminate and stock work mineralization are abundant. The amount of sulfide minerals is very small. Ancient mining is present in the area. Stream sediment geochemical study shows a very broad and high level of gold anomaly. Rock geochemical study show very high levels of Au, Ag, Cu, Pb, Zn and Au value is correlative to Cu, Pb, Zn and Ag values. Due to alteration modeling, non uniformity in mineralization and low abundance of sulfide mineralization suggest study in low sulphidation Au-Cu deposit.

    The biodiversity was studied in 26 communities with different structures in Maoershan National Park and Liangshui Natural Reserve of Northeast Forestry University in Heilongjiang Province, China. Composition index (CI) was taken as a parameter to quantify the community dynamics, which can nicely describe forest community dynamics, meanwhile, the relationship between diversity and community dynamics were also investigated and analyzed. Results showed that the total number species of community, richness, evenness, and Shannon-Wiener diversity index were obviously different in every community. The richness decreased with the increasing CI of every community, which means richness was in inverse proportion to community dynamics. The Shannon-Wiener index of every community increased from the initial stage to the middle stage of succession, and then decreased in the climax stage. The coverage weighted foliage-height diversity index increased along with the increase of CI, which was similar as the pattern diversity.

    Full Text Available Rapid Rural Appraisal (RRA methods were employed to document the use of ethnoveterinary medicinal plants in cattle by Setswana-speaking people in the Madikwe area of the North West Province of South Africa. The study indicated that Setswana-speaking people in the North West Province have a rich heritage of ethnoveterinary knowledge, which includes all aspects of ethnoveterinary medicinal plant use. Information was gathered from informants through individual interviews, group interviews, guided field walks and observations. Ethnoveterinary uses in cattle of 45 plant species representing 24 families were recorded. Plants were used in 84 % of the total number of recorded ethnoveterinary remedies. These plants were used alone (64 % or in mixtures (36 % for 29 indications. The most important indications were retained placenta, diarrhoea, gallsickness, fractures, eye inflammation, general ailments, fertility enhancement, general gastrointestinal problems, heartwater, internal parasites, coughing, redwater and reduction of tick burden. Plant materials were prepared in various ways including infusion, decoction, ground fresh material, sap expressed from fresh material, charred and dried. The most common dosage formwas a liquid for oral dosing. Other dosage forms included drops, licks, ointments, lotions and powders. Liquid remedies for oral dosing were always administered using a bottle. Medicinal plant material was preferably stored in a dried form in a cool place out of direct sunlight and wind. Lack of transfer of ethnoveterinary knowledge to younger generations puts this knowledge at risk. RRA was found to be a successful method of investigation for the study of ethnoveterinary medicine.

    In South America, cutaneous leishmaniasis is the most frequent clinical form of leishmaniasis. Bolivia is one of the countries with higher incidence, with 33 cases per 100,000 individuals, and the disease is endemic in 70% of the territory. In the last decade, the number of cases has increased, the age range has expanded, affecting children under 5 years old, and a similar frequency between men and women is found. An entomological study with CDC light traps was conducted in three localities (Chipiriri, Santa Elena and Pedro Domingo Murillo) of the municipality of Villa Tunari, one of the main towns in the Chapare province (Department of Cochabamba, Bolivia). A total of 16 specimens belonging to 6 species of the genus Lutzomyia were captured: Lu. aragaoi, Lu. andersoni, Lu. antunesi, Lu. shawi, Lu. yuilli yuilli and Lu. auraensis. Our results showed the presence of two incriminated vectors of leishmaniasis in an urbanized area and in the intradomicile. More entomological studies are required in the Chapare province to confirm the role of vector sand flies, the intradomiciliary transmission of the disease and the presence of autochthonous cases of cutaneous leishmaniasis.

    Full Text Available Development processes of a master plan formulation for flood protection and mitigation consists of the selection process of a targeted area based on risk level, developing a present and future flood inundation map and a flood risk map and identify direction and drainage capacity of the targeted area. Main causes of flooding in the area can be identified leading to designing flood protection and a flood drainage system in both structural and non-structural measures, prior to a public hearing process from stakeholders to finalize the master plan to provide maximum benefits and less negative impact. These processes are applied to Roi Et Province. Based on flood risk criteria, 24 municipalities with high risk are selected. The cause of flooding in the municipality area can be combined in 2 groups, flooding from low efficiency of storm drainage capacity and flooding from overbank flow from the Mun, Chi and Yang Rivers. Structural measures for the first and second group are the improvement of the existing system or changing a new drainage system and the improvement of existing river dikes and levees. It is also possible to design and construct a new one. Constructing a polder system for the community area, requires a budget about 3,338 million baht. To support structural measures, non-structural measures are required, for example, a flood warning system, an emergency response plan during flood disaster.

    Domestic combustion of coal for residential heating and food preparation is pervasive in the mountainous regions of Guizhou Province, SW China. The use of locally mined, high-arsenic (> 100 ppm) coals has caused an excess of 3,000 cases of arsenic poisoning restricted to several villages. Samples of several high-As coals are being studied to determine the concentrations, distributions, and form(s) of the arsenic. This information should help to determine the source of the As and better understand its behavior during the combustion process. Preliminary results from selected coal samples indicate that As contents are as high as 35,000 ppm, on a whole coal basis. The coals contain multiple As-bearing phases including arsenopyrite, As-bearing pyrite, arsenic sulfide (realgar?), Fe-As oxide, As-bearing K-Fe-sulfate (jarosite?), and As-bearing iron phosphate. Some of the organic matter appears to be suffused with organically-bound As or contains extremely fine particles of an As-rich phase, apparently an arsenate.

    OBJECTIVE To analyze positive rates of the specific proteins CagA, VacA, UreA and UreB of Helicobacter pylori (Hp) in people in Xinin city Qinghai Province, a district with a high prevalence of gastric carcinoma, and to examine the relationship among the incidence, gross diagnosis and pathologic diagnosis. METHODS The gastric tissue biopsy specimens taken under endoscopy were examined by CLO,WS and Western Blot to judge the condition of the Hp infection. The positive rates of Hp CagA,VacA,UreA and UreB that had infected patients were evaluated. RESULTS The positive rate of UreA was markedly lower in chronic superficial gastritis (CSG) than in duodenal ulcer (DU) and compound ulcer, and also lower than in chronic atrophic gastritis(CAG), gastric ulcer(GU) and gastric cancinoma. However the positive rate of UreB was notably lower in duodenal ulcer and gastric ulcer than in chronic superficial gastritis and atrophic gastritis. The rates of UreB found in intestinal epithelial metaplasia, atrophic gastritis and gastric carcinoma were notably lower than in other diseases, however, it was markedly increased in chronic superficial gastritis, No differences were found among CagA and VacA of specimens with different endoscopic diagnosis or pathologic diagnosis. CONCLUSIONS The UreA in Hp may be relevant to the pathogenic mechanism of severe gastric diseases. However, UreB may have some protective effect on severe gastric diseases.

    Background:Around 2000 plant species occur naturally in Lorestan Province of which 250 species are medicinal and myrtle is one of them. Myrtle is a shrub whose leaves and fruits have medicinal value and thus, if managed and harvested properly, could produce sustained economic benefits. In recent years, however, over half of the myrtle site areas was destroyed, due to inappropriate management and excessive harvesting practices. Thus, coming up with a practical harvesting approach along with identifying those factors damaging the sites, seems to be very crucial. Methods:In our investigation, we calculated the conservation value per hectare of myrtle in the Dooreh forest area in Lorestan Province. Using the Contingent Valuation (CV) and Double Bounded Dichotomous Choice (DBDC) methods, we determined the willingness to pay (WTP) for myrtle conservation. The WTP was estimated with a logit model for which indices were obtained based on a maximum precision criterion. Results:The results showed that 86.67 per cent of people were willing to pay for the conservation of these myrtle sites. Average monthly WTP per family was calculated as$0.79. The annual conservation value in terms of WTP for the preservation of the myrtle sites in Dooreh was estimated as$102,525. Among the variables of the model presented, education had a positive impact, while the amount proposed for payment and family size had a negative impact on the WTP. Conclusions:Our estimate of the value of myrtle conservation should provide justification for policy makers and decision making bodies of natural resources to implement policies in order to conserve the natural sites of this species more effectively.

    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.

    Full Text Available Background: Zhejiang Province, located in southeastern China, is frequently hit by tropical cyclones. This study quantified the associations between infectious diarrhea and the seven tropical cyclones that landed in Zhejiang from 2005–2011 to assess the impacts of the accompanying precipitation on the studied diseases. Method: A unidirectional case-crossover study design was used to evaluate the impacts of tropical storms and typhoons on infectious diarrhea. Principal component analysis (PCA was applied to eliminate multicollinearity. A multivariate logistic regression model was used to estimate the odds ratios (ORs and the 95% confidence intervals (CIs. Results: For all typhoons studied, the greatest impacts on bacillary dysentery and other infectious diarrhea were identified on lag 6 days (OR = 2.30, 95% CI: 1.81–2.93 and lag 5 days (OR = 3.56, 95% CI: 2.98–4.25, respectively. For all tropical storms, impacts on these diseases were highest on lag 2 days (OR = 2.47, 95% CI: 1.41–4.33 and lag 6 days (OR = 2.46, 95% CI: 1.69–3.56, respectively. The tropical cyclone precipitation was a risk factor for both bacillary dysentery and other infectious diarrhea when daily precipitation reached 25 mm and 50 mm with the largest OR = 3.25 (95% CI: 1.45–7.27 and OR = 3.05 (95% CI: 2.20–4.23, respectively. Conclusions: Both typhoons and tropical storms could contribute to an increase in risk of bacillary dysentery and other infectious diarrhea in Zhejiang. Tropical cyclone precipitation may also be a risk factor for these diseases when it reaches or is above 25 mm and 50 mm, respectively. Public health preventive and intervention measures should consider the adverse health impacts from tropical cyclones.

However, knowledge about the explanation of forest area changes is far from completeness. Therefore, this research integrates natural environmental information with socio-economic processes and policy changes to build the econometric model to explore the driving mechanism for forest area changes from 1988 to 2005. Tobit regression analysis was used to measure socio-economic and natural factors. The estimation results show that the influencing factors for forest area include population, per capita GDP and location factors on forest area changes. The research finds that one possible way to promote the reforestation is to improve the economic development level, particularly to quicken the pace of infrastructure construction, of less developed areas in Jiangxi Province. And promoting transfer of rural surplus labor of Jiangxi Province may also be beneficial to relieve stresses of deforestation for farmland reclamation. The research results could

    Full Text Available Rodent-borne disease surveillance was conducted at Nightmare Range (NM-R, near the demilitarized zone in northeast Gyeonggi Province, Republic of Korea, to identify hemorrhagic fever with renal syndrome (HFRS risks for a mountainous high-elevation (500 m military training site. Monthly surveys were conducted from January 2008-December 2009. A total of 1,720 small mammals were captured belonging to the Orders Rodentia [Families, Sciuridae (1 species and Muridae (7 species] and Soricomorpha [Family, Soricidae (1species]. Apodemus agrarius, the primary reservoir for Hantaan virus (HTNV, accounted for 89.9% (1,546 of all small mammals captured, followed by Myodes regulus (4.0%, Crocidura lasiura (3.9%, Micromys minutus (1.4%, Mus musculus (0.3%, Microtus fortis (0.2%, Apodemus peninsulae (0.2%, Tamias sibiricus (0.1%, and Rattus norvegicus (<0.1%. Three species were antibody-positive (Ab+ for hantaviruses: A. agrarius (8.2%, M. minutus (4.2%, and C. lasiura (1.5%. HTNV specific RNA was detected in 93/127 Ab+ A. agrarius, while Imjin virus specific RNA was detected in 1/1 Ab+ C. lasiura. Overall, hantavirus Ab+ rates for A. agrarius increased with weight (age and were significantly higher among males (10.9% than females (5.1% (P<0.0001. High A. agrarius gravid rates during the fall (August-September were associated with peak numbers of HFRS cases in Korea that followed high gravid rates. From 79 RT-PCR positive A. agrarius, 12 HTNV RNA samples were sequenced and compared phylogenetically based on a 320 nt sequence from the GC glycoprotein-encoding M segment. These results demonstrate that the HTNV isolates from NM-R are distinctly separated from HTNV isolated from the People's Republic of China. These studies provide for improved disease risk assessments that identify military activities, rodent HTNV rates, and other factors associated with the transmission of hantaviruses during field training exercises.

    The Chihuahua Basin and Range (CBR) is the eastern branch of the northern Mexican Basin and Range Province that, from a morphostructural point of view, presently is one amongst the lesser-known zones of the southern portion of the North America Basin and Range Province. The study area covers an approximately 800 km2-wide portion of the CBR and encompasses the fault-bounded Charco basin and its surrounding areas. The bedrock of the area pertains to the large siliceous-igneous province of the Sierra Madre Occidental and consists of volcanoclastic rocks including Oligocene dacite, rhyolite, rhyolitic tuffs, and polimitic conglomerates. The region is characterized by a series of NW-SE oriented valleys delimited by tilted monoclinal blocks bounded by high angle, SW-dipping, normal faults. Abrupt changes in elevation, alternating between narrow faulted mountain chains and flat arid valleys or basins are the main morphological elements of the area. The valleys correspond to structural grabens filled with Plio-Pleistocene continental sediments. These grabens are about 10 km wide, while the extensional fault system extend over a distance of more than 15 km. The mountain ranges are in most cases continuous over distances that range from 10 to 70 km including different branches of the extensional and transfer faults. The morphogenesis is mainly erosive in character: erosional landforms (such as rocky scarps, ridges, strath-terraces, erosional pediment, reverse slopes, landslide scar zones, litho-structural flat surfaces) dominate the landscape. In contrast, Quaternary depositional landforms are mainly concentrated within the flat valleys or basins. The Quaternary deposits consist of wide alluvial fans extending to the foot of the main ridges, fluvial and debris-slope deposits. The morphostructural characterization of the area integrated different methodologies, including: i) geomorphological and structural field analyses; ii) remote sensing and geo-morphometric investigations

    Human activity is the main driving force of the change of land cover and landscape patterns. However, there are few studies focusing on the mechanism of human-induced change of land cover and landscape patterns at village scale. In this study, taking low-slope hilly area of Dali City, Northwestern Yunnan Province as a case study area, high resolution satellite images were introduced to find out the rules of land cover and landscape pattern changes, i.e. GeoEye-1 of 2009 and World- View-3 of 2014. The object-oriented and human-computer-interaction approaches were applied to interpret the images using ArcGIS 10.2 and ENVI 5.2. The results showed that, the main land cover types in the study area were forest land, paddy field and dry land in 2009, with forest, bulldozed unbuilt ground and paddy field in 2014, accounting for 82.8% and 70.9% of the total area, respectively. The land cover transition showed that, during 2009-2014, the main land cover change flows were from forest land, paddy field and dry land, to bulldozed unbuilt ground and construction land. Furthermore, the area of bulldozed but unbuilt land had increased to be 531.57 hm² in 2014, which mainly came from forest land (42.8%), dry land (21.7%), and paddy field (14.2%). Landscape pattern change was characterized as the increase of patch quantity and density, the decrease of mean patch size, the complication of patch shape, the fragmentation of landscape patches, and the diversification of landscape patterns.

    Leal Insua, Maria Pilar

    This thesis is focused on the Scientific area of the Programs of Curricular Diversification, one of the Government actions for the attention to diversity in compulsory Secondary Education, established in the General Education Law (LOGSE: Ley de Ordenacion General del Sistema Educativo) of 1990. It has been carried out in Spain. In the thesis two different lines of work can be distinguished: (A) The analysis of material elaborated specifically for the mentioned area. We intent to know what materials have been elaborated and to analyze them; to this purpose we study the material spread in Congresses or Conferences, and also the articles published in magazines or specifically designed to be used in the Scientific area of the Programs of Curricular Diversification until year 2003. The analysis is made after classifying the material according to the format in which it appears (books, CDs, "Didactic Units"). (B) Two case studies, of evaluative character, carried out in two Secondary Schools in the province of Segovia (Spain), one of them in the city and another one in a rural population. The case studies are centered in the Scientific Area of the Programs of Curricular Diversification that last for two years. In the first of these Centers eight students took part in the Program; in the second, a total of seven. Throughout the investigation we observed that students who took part in the Programs obtained good academic results. Programs are proved to be effective in generating processes of academic success in pupils who were previously in situation of school failure and at risk of social exclusion. The success of these programs is fundamentally due to the following reasons: the low number of students involved, the fact that they are focused on basic knowledge, the reduced number of subjects studied. Besides, to offer the students the chance of a closer relationship with a few teachers increases their motivation and involvement in the programs. Key words: Attention to

  10. Deep-seated structure and metallogenic dynamics of the Ailaoshan polymetallic mineralization concentration area, Yunnan Province, China

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    The Ailaoshan poly-metallic mineralization concentrated area (MCA) consists of the well known Ailaoshan metallogenic belt and adjacent mineral districts and/or deposits. Located in an area of several complex and intersecting tectonic units, the Ailaoshan poly-metallic MCA is controlled by deep crustal and mantle tectonism. Through interpretation of remote sensing images, we identified a large ring structure system that surrounds the MCA. This ring structure encloses regional deep-crustal faults, ductile shear zones, geothermal anomalies, magmatic rocks, and the major mineral deposits, all of which are the reflections of deep tectonic geodynamics that have been long active in this area. Geophysical data indicate that the crust is comprised of relatively stable two or three layers, with some irregular lower-velocity belts. The Moho in the ring sutures occurs as an area of local uplift. There exists an obvious transitional zone between the crust and mantle boundaries. Asthenopheric mantle shows multi-layer upwelling, which indicates multiple events during different geological epochs. It is believed that these mantle events or pulses were responsible for the formation of the regional shear zones, magmatic rocks, and polymetallic orebodies. Furthermore, an integrated metallogenic dynamics model related to the asthenopheric upwelling pulses in the MCA is established, defining events as old as Late Paleozoic.

    The environmental behavior of the residents depends on their perception of environmental pollution. Hence, it is important for scientific and policy experts to research on the impact of the environmental pollution perception of local residents. Owing to the richness of natural resources, Hancheng coal mine areas are abound in heavy industries, and environmental pollution is serious and typical in this area, thus, the residents are anxious about their health. Using questionnaires, this paper surveys the perception of residents living in the coal mine area. The influential factors of environmental perception were analyzed by the Rank Sum Test. The results were: (1) the majority of the residents in the coal mine area are not satisfied with their living environment. The perception order of pollution severity is: air pollution > noise pollution > sanitation > water pollution. The residents think that pollution is mainly caused by coal processing. Hence, coal mining is not the main reason of the pollution in the coal mine area. (2) Age and length of residence have significant positive effects on perceptions of air, water, and noise pollutions; whereas education has a significant negative effect on perceptions of water and noise pollutions, as well as sanitation. This phenomenon can be explained by the various cultural groups having varied perceptions on the environmental pollution. In addition, proximity to mine has significant negative effect on perceptions of water and noise pollution. In conclusion, the paper discusses the effects of demographical and social factors on the perception of environmental pollution and gives suggestions on the planning and management of the environment.

    Vulnerability which quantifies the loss ratio under different hazard intensity is an important feature of the natural disaster system and has important significance to natural disaster risk assessment. Agriculture is an outdoor industry with high risk of meteorological disasters. The strong winds, heavy rain and storm surge are main typhoon hazard factors to crops. To provide a quantitative research method for the loss evaluation of crops due to typhoon disaster we first revised two vulnerability curves for crops under comprehensive intensity of typhoon based on the simulated hazard data and loss data related to historical typhoon events landing on China from 1949 to 2014;and then established a storm surge vulnerability matrix of crops regarding Zhanjiang City of Guangdong Province as the study area ; finally, we put forward three storm surge fragility curves for crops representing different states of loss. The results can effectively describe the typhoon vulnerability for crops in China coastal areas so as to provide the input to post-disaster loss assessments and catastrophe modeling applications.

    Based on the investigation data of the vegetations in Hegou valley in Wuqi County of Shaanxi Province, this paper studied the vegetation characteristics on the five typical micro-topography categories including shallow gully, gully, collapse, platform, and scarp in the loess area of north Shaanxi, with the undisturbed slope as the control. There existed distinct differences in the species composition, quantitative characteristics, and species diversity of plant communities on the five typical micro-topography categories and the undisturbed slope. After twelve years of enclosure recovery, the study area formed herbaceous plant community, with Artemisia sacrorum and Artemisia giraldii as the dominant species. Among the main companion species, shrubs such as Prinsepia uniflora and Caragana korshinskii were found in scarp and gully, and hygrophyte Phragmites australis appeared in platform. The coverage, height, and biomass of the plant communities on most of the micro-topography categories, especially on the gully and collapse, were larger than those on the undisturbed slope. The Shannon index on the micro-topography categories and undisturbed slope was in the order of scarp > gully > shallow gully > undisturbed slope > platform > collapse.

    Among strategies to prevent HIV, other sexually transmitted infections (STIs) and unwanted pregnancies, are programs that promote sexual abstinence among adolescents. However, literature suggests that there may be differences in the understanding of abstinence across adolescents, and this study sought to explore the understanding of sexual abstinence among both male and female learners in a secondary school in a semi-rural area of North West Province, South Africa. Focus group discussions were used to collect data from learners who were in grades 8-10 at the time of the study. The findings are that the learners in this area understand sexual abstinence as the decision not to have sex, and this was associated with prevention of HIV, STIs and unwanted pregnancies, which ensures a better future. Barriers to sexual abstinence include peer pressure, myths and wrong perceptions about sex, influence of drugs and alcohol and the influence of television. Based on how it is delivered, school-based sex education was viewed as both an enabler and barrier to sexual abstinence. It is recommended that programs to promote sexual abstinence be strengthened and such programs be community-based. PMID:27315574

    Background: Prenatal exposure to organophosphorous (OP) pesticides has been found to be associated with adverse effects on child neurodevelopment, but evidence on potential effects induced by both prenatal and postnatal OP exposure in infants is limited. Objectives: Our aim was to investigate the associations of both prenatal and postnatal OP exposure with birth outcomes and infant neurodevelopment. Methods: Exposure to OP in 310 mother–infant pairs was assessed by measuring dimethylphosphate (DM), diethylphosphate (DE), and total dialkylphosphate (DAP) metabolites in urines from pregnant women and their children at 2 years of age. The Gesell Developmental Schedules was administered to examine neurodevelopment of 2-year-old children. Results: Based on the Gesell Developmental Schedules, the proportions of children with developmental delays were < 6%. Adverse associations between head circumference at birth and prenatal OP exposure were demonstrated. Both prenatal and postnatal OP exposure was significantly associated with increased risk of being developmentally delayed. Specifically, odds ratio (OR) value for prenatal DEs was 9.75 (95% CI: 1.28, 73.98, p = 0.028) in the adaptive area, whereas in the social area, OR values for postnatal DEs and DAPs were 9.56 (95% CI: 1.59, 57.57, p = 0.014) and 12.00 (95% CI: 1.23, 117.37, p = 0.033), respectively. Adverse associations were observed only in boys, not in girls. Conclusions: Both prenatal and postnatal OP exposure may adversely affect the neurodevelopment of infants living in the agricultural area. The present study adds to the accumulating evidence on associations of prenatal and postnatal OP exposure with infant neurodevelopment. Citation: Liu P, Wu C, Chang X, Qi X, Zheng M, Zhou Z. 2016.

  5. Uranium Provinces in China

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

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

    根据2006年7月对江苏近海水域水环境调查的资料,对江苏近海的水质进行评价.结果表明:江苏近海水域pH、活性磷酸盐、砷、铜、镉、锌、总铬等指标均达到GB 3097-1997《海水水质标准》中Ⅱ类水质标准,但是溶解氧、总磷、总氮与铅超标率较高,超标率分别达到79.10%,54.35%,34.15%和41.46%,无机氮和汞浓度超标率较低.此外,海水中还有轻微的油污染.从北至南3个海域中海州湾水质相对较好,辐射沙洲与长江口北支海域污染较为严重,并且辐射沙洲海域超标站位分布凌乱,无规律可循.%Based on a survey of the marine environment in the coastal water areas of Jiangsu Province in July of 2006, an assessment of the quality of coastal water in Jiangsu Province was conducted. The results show that indices including pH, active phosphate, As, Cu, Cd, Zn, and total chromium all reached the Grade II standard of the National Marine Water Quality Standards (GB 3097-1997). However, the concentrations of DO, TP, TN, and Pb exceeded the Grade Ⅱ standard, by 79.10%, 54.35%, 34.15%, and 41.46%, respectively. The concentrations of inorganic nitrogen and Hg had relatively low standard-exceeding rates. In addition, the marine water was slightly polluted by oil. Of the three coastal water areas from the north to the south, the water quality in Haizhou Bay was relatively good, while the water pollution in the coastal zone of radial sand ridges and the north branch of the Yangtze Estuary were relatively serious. Furthermore, the distribution of the monitoring points with standard-exceeding rates was irregular in the coastal zone of radial sand ridges.

    Mine exploitation has a significant impact on the ecological environment status of the surroundings. To analyze the impact of Tonglvshan Mining area to its surroundings, this paper adopted the spatiotemporal methodology based on the extracted Eco-environmental Quality Index (EQI) to analysis the extent and degree of the effect. The spatiotemporal methodologies are based on two scales: buffers and administrative units. EQI includes Biological Abundance Index (BAI), Vegetation Index (VI), Water Network Density Index (WNDI), and Land Degradation Index (LDI). The weight of each Index was determined by the analytic hierarchy process (AHP) and scores of the experts. The calculating of EQI was referenced to the standard "Technical criterion for Eco-environment Status Evaluation" HJ/T192-2006 and the "Standards for Classification and Gradation of Soil Erosion" SL 190-96. Considering ecological and environmental characteristics relevant to China, this method has been widely used to study the environment status of specific regions in China. The assessment based on buffers adopted the radius of 300m, 500m, 700m, 1000m, 1500m, 2000m, 2500m, 3000m, 3500m, and 4000m as the buffers in 3 typical miners respectively. The calculated result indicates that, the REI is increasing with the radius and the increasing rate becoming smaller until REI is stable. Which means the effect of miner is getting weaker with the distance to the miner is increasing and the effect is diminished when the distance is far enough. The analysis of the 3 typical miner shows that the extent and degree of the effect of miner relates not only with the area of the miner, but also with type of mineral resource, the status of mining and the ecological restoration. The assessment was also carried out by calculating the EQI in 14 administrative units in Daye city in 2000, 2005, and 2010. The study shows that the EQI is decreasing in 14 units from 2000 to 2010. The spatiotemporal analysis of the type and area of land

    Water is the key factor in vegetation growth in a loess area. Researchers have been keen on the study of tree transpiration for a long time. To provide a scientific basis and practical instruction for vegetation reconstruction and recovery in a loess area, the paper measured and calculated the water consumption of potted Platycladus orientalis, Robinia pseudoacacia, Armeniaca vulgaris and Pyrus hopeiensis separately during the growing season (from Apr. to Nov,). The four were the main afforestation species in a loess area of western Shanxi based on the principle of water balance. Using data on soil water dynamics and the range of available moisture on potted mature trees, the relationship between water supply and consumption and soil moisture availability and deficit state were analyzed. Several conclusions are listed as follows: 1) In the dry year (2002), during the growing season the precipitation was 430.7 mm and the water consumption of potted trees was from 430 to 490 mm. More water consumption and less available water supply occurred, showing a serious water deficiency. In the rainfall-rich year (2003), during the growing season the precipitation was 870.2 mm and the water consumption of potted trees was from 480 to 515 mm. Due to the uneven distribution of rainfall, the water budget balance was slightly affected in May and November. 2) The curves of soil water content of different species had similar annual changes, although the trends were different in the same month, and those of the same tree species in different test plots also had different trends in the same month. 3) Non-available soil water content of Platycladus orien-talis, Robinia pseudoacacia, Armeniaca vulgaris and Pyrus hopeiensis was less than 8.0%, 8.4%, 9.2% and 9.7% respectively, which indicated that Pyrus orentalis used water more efficiently than the others. In the dry year (2002), for several months, soil water content of potted trees was lower than its threshold value for non

    International Nuclear Information System (INIS)

    The present study is a part of our investigations comprising (a) characterization of the tannery/leather industry effluents, (b) assessment of the pollution caused by these effluents to the environment, and (c) development of a simple but economical procedure for the pre-treatment and recycling of these effluents, to recover some valuable materials. In NWFP, the tanning industry has shown a rapid development in the late seventies, during which large-size industrial units were established at Peshawar, Charsadda and Jehangira. Since no pollution control measures are being adopted by these units, the hazards to the environment caused by the effluents and emissions from tanneries pose an acute problem in the country. The studies narrated below indicate that the under-ground water samples around tanneries have high concentrations of TDS, phenols, chromium and sulfides, which render the well-water in the area unsuitable for drinking and domestic uses.

    For improving the environmental quality and ensuring supply of wood and non-timber forest products, many forests have been planted in plain areas of China. Scientists have studied their benefits, almost all of the approaches were based on fixed-point data, and few was considered on the non-efficient factors and temporal scale effects. This paper studies the positive and negative benefits at a large temporal scale, and the effects of plain afforestation on stockbreeding and rural economy. The benefits of plain afforestation, correlation coefficiency of agroforestry and production factors are analyzed via stochastic frontier modeling in Huanghuaihai Plain Area of China; elastic coefficient of agroforestry, husbandry, farming, and total output of agricultural sector are calculated through adopting partial differential equation. Some conclusions can be drawn that, plain forests have an important effect on the development of plain agriculture. But shelterbelts and small-scale forests have different effect on the development of agricultural economy. Shelterbelts have negative effect on the industries, but small-scale forest has positive effect. On the whole, contribution of forest resource to value of animal husbandry and gross production value of agriculture is positive, and to the value of farming is negative.

    Full Text Available The Halak Abad prospect occurs in the northeastern part of Central Iran zone (Sabzevar structural zone. In this investigation, geochemical evolution, age and source of part of northeastern Iran magmatic arc (intrusive bodies in Halak Abad area in the Khorasan Razavi province has been studied. The exposed rocks consist of volcanic rocks with andesite and dacite nature, limestone, plutonic rocks mostly diorite, quartz diorite, monzodiorite, quartz monzonite, granodiorite and granite and sedimentary rocks such as limestone, sandstone and conglomerate. Magnetic susceptibility of intrusive rocks is >100 × 10-5 SI, so they belong to the magnetite-series (oxidized. This magmatism is mainly low-K (tholeiite series and meta-aluminous. The amounts of Zr, Th, Nb and Ti show depletion compared to N-MORB. Trace elements behavior shows a nearly flat pattern. Age of granodiorite body based on U-Pb zircon dating is 99.7±1.8 Ma (Mid-Cretaceous and 87Sr/86Sr initial ratio is 0.7047. The geochemical signature and 87Sr/86Sr initial ratio in the area suggest volcanic arc magmatism in subduction zone. This magmatism has characteristic such as high Na2O (3-7 %, low K2O (0.12-1 %, high CaO (4-5.7%, low Rb (1-20 ppm, low total REE (<40 ppm, high Ba/Nb, Sm/Yb<2, (La/YbN<5, 87Sr/86Sr initial ratio < 0.7045 and εNd: +4.5 show differences with normal granitoids in subduction zones. Geochemical and petrological characteristics indicate melting in relatively low pressure (shallow depth. The lines of evidence demonstrate that formation of this granitoid needs a suprasubduction zone.

    2016-10-01

    Full Text Available In this paper, we propose a multiple kernel relevance vector machine (RVM method based on the adaptive cloud particle swarm optimization (PSO algorithm to map landslide susceptibility in the low hill area of Sichuan Province, China. In the multi-kernel structure, the kernel selection problem can be solved by adjusting the kernel weight, which determines the single kernel contribution of the final kernel mapping. The weights and parameters of the multi-kernel function were optimized using the PSO algorithm. In addition, the convergence speed of the PSO algorithm was increased using cloud theory. To ensure the stability of the prediction model, the result of a five-fold cross-validation method was used as the fitness of the PSO algorithm. To verify the results, receiver operating characteristic curves (ROC and landslide dot density (LDD were used. The results show that the model that used a heterogeneous kernel (a combination of two different kernel functions had a larger area under the ROC curve (0.7616 and a lower prediction error ratio (0.28% than did the other types of kernel models employed in this study. In addition, both the sum of two high susceptibility zone LDDs (6.71/100 km2 and the sum of two low susceptibility zone LDDs (0.82/100 km2 demonstrated that the landslide susceptibility map based on the heterogeneous kernel model was closest to the historical landslide distribution. In conclusion, the results obtained in this study can provide very useful information for disaster prevention and land-use planning in the study area.

    Full Text Available Background Sporozoan protozoa and enteroparasites cause gastroenteritis. Sporozoa are the major cause of self-limiting diarrhea in immunocompetent patients, however they cause serious diseased in patients with immunosuppression. Objectives The current study aimed to identify the prevalence of sporozoa and enteroparasites among patients with gastroenteritis referred to the healthcare centers in seven provinces of Iran. Patients and Methods In this cross-sectional study, 4200 stool samples were randomly collected from patients with gastroenteritis in the selected hospitals of Gilan, East Azerbaijan, Qazvin, Kurdistan, Mazandaran, Tehran and Khorasan-e-Razavi provinces. Primarily samples were examined directly for enteroparasites. The samples were then filtered and concentrated using Paraseb kit. The pellets were fixed, stained by different assays including acid fast staining, Auramin Phenol Fluorescence, Giemsa and light microscopy. Results The results revealed the overall rate of infection, 3.86% (163 cases, as an indicator of parasitic enteropathogens in Iran. Among the provinces, Khorasan-e-Razavi and Mazandaran with 8.83% (53 cases and 0.34% (2 cases showed the highest and lowest rates of infection, respectively. The frequencies of sporozoa including Cryptosporidium, Microsporidium, Isospora and Cyclospora spp. were 0.1%, 0.1%, 0.07% and 0.02% respectively. Among the parasites, Giardia lambelia, Taenia saginata and Hookworms with 1.78% and 0.02% had the highest and lowest rates of infection, respectively. Regarding the age groups, the highest and the lowest rates of infection were in 0 - 10 (48% and 41 years old and above (6.7% groups, respectively. Conclusions Despite relatively low prevalence of sporozoa, giardiosis is the most prevalent agent for gastroenteritis amongst 3.86% of parasitic infections in Iran. The current study confirmed the abundance of infection in warm and wet seasons, and more frequency of infections among children than

    Marine environmental samples including seawater (filtered and unfiltered), suspended particles, and green mussels (Perna viridis) were collected from Sriracha and Angsira areas located in Chonburi province in order to determine Po-210 radioactivity. The former was chosen because it is generally believed that this area has been contaminated by one of the largest industrial estates in Thailand and others human-activities (non-nuclear activities) nearby such as oil refineries and Coal Power Plants. Discharges, ashes, and wastes released from these activities may result in an increase of Po-210 concentration in marine environment when compared to other areas. The later was designated to serve as a control site in this study since this area is unlikely to be impacted by industrial activities. Our results revealed that, in the filtered seawater, averaged values of Po-210 level were 0.26 + 0.14 mBq/L (Sriracha) and 0.56 + 0.42 mBq/L (Angsira) and, in the unfiltered seawater, means of Po-210 radioactivity were 2.37 + 0.32 mBq/L (Sriracha) and 4.20 + 2.78 mBq/L (Angsira). Furthermore, the suspended particles contained Po-210 concentrations with averaged values of 14.11 + 8.87 Bq/kg dw (Sriracha) and 102.21 + 51.49 Bq/kg dw (Angsira) while averaged Po-210 levels of 35.74 + 17.53 Bq/kg dw (Sriracha) and 71.12 + 62.88 Bq/kg dw (Angsira) were found in the green mussels examined. The present finding indicates that there is no radiological impact caused by those human activities to the marine environment at Sriracha. Radiation dose assessment was also performed in both the green mussels and human who consume green mussels. The results show that the green mussels farmed at Sriracha and Angsira received averaged radiation dose rates from Po-210 at 0.0007 and 0.0015 mGy/d, respectively. In addition, our results reveal that populations living in Chonburi province and ingesting the green mussels from these 2 locations received radiation dose rates from Po-210 at the means of 44.25 and

    Whole-rock Sm-Nd Isotopes were investigated for Cambrian-Ordovician strata from the Jinggangshan area beTween the Yangtze Block and Cathysla Block in South China. These strata were deposited as a greatly thick unit of muddy-sandy laminas with intercalated carbonate and organic carbon-bearing layers. They have low ε(t) values of -13.9 to -7.9 and old Nd model ages of 1842 to 2375 Ma. In t-tdiagram, they are far away from the concordant line but fall within the evolution zone of the Proterozoic crust of South China. This indicates that the Cambrian-Ordovician strata are mainly composed of mat-ters eroded from ancient Paleoproterozoic crust that may mainly consist of continental-derived detrital sediments with high maturity in the Cathyaia Block. However, the Ordovician Jueshangou Formation and Dui'erehi Formation have ε(t) values of -10.5 and -7.9 at the higher end of the above range and Nd model ages of 1842 to 2059 Ma at the lower end of the above range. This suggests involvement of more detritus that were eroded from the relatively juvenile crust from Late Paleoproterozoic to the Early Neoproterozoic. All the Nd model ages for the Cambrian-Ordovlcian sedimentary rocks in the Cathysia Block and the southeastern margin of the Yangtze Block are older than 1800 Ma, suggesting that no material from the Early Paleozoic depleted mantle-derived magmas was involved in these regions.

    OBJECTIVE To investigate the risk factors of colon cancer in Jiashan county, the highest incidence area in China and to provide a scientific basis for monitoring and prevention. METHODS With a population-based case-control study, 109 colon cancer patients with 1:7 matched controls were interviewed with uniform questionnaires. Conditional logistic regression was used for univariate and multivariate analysis of colon cancer. RESULTS High monthly pork consumption (OR=1.608), and high monthly animal fat consumption (OR=1.391) over a ten-year period, psychological depression (OR=9.887), negative emotion (OR=1.723), lower digestivetract diseases (OR=4.163), and history of colorectal cancer in first-degree relatives (OR=3.421) were the main risk factors of colon cancer. During that time, high monthly vegetable consumption was a protective factor for colon cancer (OR=0.422).CONCLUSIONS Colon cancer in Jiashan county was related to dietary factors. The research results support the colon cancer etiological hypothesis of "fat-bile acid" and "deficiency of dietary fibre". Psychological depression, in heritance and lower digestive tract diseases were also correlated with colon cancer.

    A seasonal rodent-borne disease surveillance program was established at Dagmar North Training Area located near the demilitarized zone, Republic of Korea, from 2001 through 2005. Selected habitats surveyed included earthen banks separating rice paddies, fighting positions along a 5 m rock-faced earthen berm, and extensive tall grasses with various degrees of herbaceous and scrub vegetation associated with dirt roads, rice paddies, ditches, ponds, or the Imjin River. Of the nine species of small mammals captured, the striped field mouse (Apodemus agrarius), the primary reservoir for Hantaan virus, was the most frequently collected, representing 92.5% of the 1,848 small mammals captured. Males were captured similarly to females during the spring and summer seasons but were captured less frequently during the fall and winter seasons. Gravid rates were highest in the fall (25.5-57.3%) with the lowest rates during the summer (0.0-2.2%). Capture rates were the lowest along earthen banks separating rice paddies (5.5%) and highest in unmanaged tall grasses and crawling vegetation (15.3-43.5%). An increased knowledge of ecological factors that impact the abundance and distribution of small mammals and the associated ectoparasites and pathogens they harbor is critical for developing accurate disease risk assessments and mitigation strategies for preventing vector- and rodent-borne diseases among soldiers training in field environments.

    Understanding mercury (Hg) methylation/demethylation processes and the factors controlling methylmercury (MeHg) production within the rice paddy ecosystem of Hg mining areas is critical to assess the risk of MeHg contamination in rice grain. Two typical Hg-contaminated mining sites, a current-day artisanal site (Gouxi) and an abandoned site (Wukeng), were chosen in this study. We qualified the in situ specific methylation/demethylation rate constants in rice paddy soil during a complete rice-growing season. Our results demonstrate that MeHg levels in rice paddy soil were a function of both methylation and demethylation processes and the net methylation potential in the rice paddy soil reflected the measured MeHg production at any time point. Sulfate stimulating the activity of sulfate-reducing bacteria was a potentially important metabolic pathway for Hg methylation in rice paddies. We suggest that bioavailable Hg derived from new atmospheric deposition appears to be the primary factor regulating net MeHg production in rice paddies. PMID:27176759

  7. Effects of modern and ancient human activities on mercury in the environment in Xi'an area, Shannxi Province, P.R. China

    International Nuclear Information System (INIS)

    Samples of water, soil, sediment, and pomegranate were collected from Xi'an and the Qinshihuang Mausoleum in Shaanxi Province, China to assess the effects of human activities on mercury in the environment. The total mercury concentrations ranged from 3.9 to 992.7 ng L-1 for the water samples, 40.6 to 2204.0 ng g-1 for the soil samples, 14.2 to 376.7 ng g-1 for the sediment samples, and 0.22 to 1.74 ng g-1 for the pomegranates samples. The higher values in the water samples collected from the rivers closer to and downstream of the city resulted from wastewater discharges.

    AIM: To characterize the protein files in blood from same patients with esophageal squamous cell carcinoma (ESCC)before and after operation at the high-incidence area for ESCC in Henan Province, China.METHODS: Two-dimensional electrophoresis, silver staining and ImageMaster 2-DE analysis software were applied to the determination of protein files in the blood obtained from normal controls and ESCC patients before and after operation.RESULTS: A total of 655, 662 and 677 protein spots were identified, respectively, from the normal controls and ESCC patients before and after operation. No significant difference in the number of protein spots was observed between the normal group and ESCC patients. A total of seven protein spots were identified with a dramatic difference among the samples before and after operation. Six protein spots were up-regulated and one protein spot was down-regulated in the group after operation compared with those in normal and before operation. Three protein spots were further characterized by matrix-assisted laser desorption/ionization time of flying mass spectrometry (MALDI-TOF-MS). The proteins from these three spots were identified as serum amyloid A(SAA), amyloid related serum protein and haptoglobin.CONCLUSION: Serum amyloid A, amyloid related serum protein and haptoglobin may be related with ESCC and/or surgery. The significance of these proteins needs to be further characterized. The present study provides informative data for the establishment of serum protein profiles related with ESCC.

    Lancang-Mekong River Basin is one of ecoregions with rich biodiversity and high ecological values in the world. The basin has been strongly affected by human activities, particularly by dam construction. This study was conducted to investigate the vegetation distribution patterns in the dam areas along middle-low reach of the Lancang-Mekong River in Yunnan Province of China, where eight cascade dams have been planned or are being constructed. To identify the vegetation composition and structure, we sampled 126 quadrats along the transects arrayed vertically to both side of river channel from the year of 2004 to 2010. We found that the forest, shrub and grass communities were widely spread along the riverside. In low reach watershed of the Lancang-Mekong River, the dominated vegetations were grasses and shrubs which were severely disturbed by human activity. In middle reach of the Lancang-Mekong River, the dry-hot valley vegetation was found in the low valley. At high altitude, the pine forest and semi-evergreen seasonal forest were found. As a result of dam construction and operation, the structure and compositions of riparian vegetation were strongly changed. Some plants declined or disappeared due to the alteration of their habitats. The protection or restoration interventions are urgently needed to mitigate the risk of vegetation damage associated with dam projects along middle and low reach of the Lancang-Mekong River.

  14. Willingness of Rural Households in Mountainous Areas towards Land Transfer——A Case of Beiliang Village, Wuxiang County, Shanxi Province

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    In this paper, the Beiliang Village, Wuxiang County of Shanxi Province is chosen as the study object. The methods investigation and interview are applied. And then the status quo of land transfer is analyzed from the aspects of private land transfer, the form of land transference, the land transfer fee, the contracts of the land transfer and farmers’ knowledge on land transfer law and so on. Through the investigation and research on peasant households’ willingness towards land transfer and the factors that affect the land transfer, the willingness of farmers’ land transfer in recent years are transferred. Farmers’ land transfer willingness in recent years is clear. On the strength of the analysis, the scientific basis for the reasonable transfer of land in mountainous areas is put forward for optimizing the land distribution and promoting the sustainable and healthy development of rural economy. The countermeasures aim at accelerating land transfer, increasing farmers’ income; stringing the development of rural education, increasing the support on three agricultural problems concerning agriculture, countryside and farmers, and standardizing the rural land transfer behaviors are put forwarded as well.

    Full Text Available The plant and tetrapod fossil record of the Cañadón Asfalto Formation (Middle to Late Jurassic found in Cerro Cóndor area (Chubut Province is summarized here. The flora is dominated by conifers (Araucariaceae, Cupressaceae sensu lato but also includes ferns and equisetaleans. The tetrapod fauna is composed of dinosaur taxa described in the 70's as well as other remains recently described and other vertebrate groups such as amphibians, turtles, and mammals. The amphibian remains have been interpreted as representatives of a new species of Notobatrachus, considered one of the most basal members of the anuran lineage. Similarly, turtle remains have been recently recognized as a new species of basal turtle, bringing valuable information about the early evolution of this group. The dinosaur remains are largely dominated by saurischian taxa, represented by basal forms of Eusauropoda and Tetanurae. In addition, three different mammalian species have been identified and considered as early representatives of an endemic Gondwanan mammalian fauna. The fossil record of this formation represents the most completely known biota from the continental Middle to Late Jurassic of the Southern Hemisphere and one of the most complete of the entire world.

    This study was conducted to evaluate the quality of surface water and shallow groundwater near a rare earth mining area in southern Jiangxi Province, China. Water samples from paddy fields, ponds, streams, wells, and springs were collected and analyzed. The results showed that water bodies were characterized by low pH and high concentrations of total nitrogen (total N), ammonium nitrogen (NH4 (+)-N), manganese (Mn), and rare earth elements (REEs), which was likely due to residual chemicals in the soil after mining activity. A comparison with the surface water standard (State Environmental Protection Administration & General Administration of Quality Supervision, Inspection and Quarantine of China GB3838, 2002) and drinking water sanitary standard (Ministry of Health & National Standardization Management Committee of China GB5749, 2006) of China revealed that 88 % of pond and stream water samples investigated were unsuitable for agricultural use and aquaculture water supply, and 50 % of well and spring water samples were unsuitable for drinking water. Moreover, significant cerium (Ce) negative and heavy REEs enrichment was observed after the data were normalized to the Post-Archean Australian Shales (PAAS). Principal component analysis indicated that the mining activity had a more significant impact on local water quality than terrace field farming and poultry breeding activities. Moreover, greater risk of water pollution and adverse effects on local residents' health was observed with closer proximity to mining sites. Overall, these findings indicate that effective measures to prevent contamination of surrounding water bodies from the effects of mining activity are needed.

    Full Text Available Background: Field studies confirmed that unusually long-tubed populations of Pelargonium dipetalum from between Swellendam and Albertinia, Western Cape Province, South Africa, are a distinct ecotype adapted to pollination by the long-proboscid fly, Prosoeca longipennis. The geographical and morphological isolation of these populations suggests that they are reproductively isolated from short-tubed populations, which are pollinated by bees.Objectives: To determine and describe the floral variation in P. dipetalum, with a view to recognising the long-tubed populations at some taxonomic level.Method: All available collections were measured and compared.Results: Populations of P. dipetalum were segregated into a short-tubed form with hypanthium 3 mm – 24 mm long and mostly pink petals that occurs from Betty’s Bay to Knysna, and a long-tubed form with the hypanthium 34 mm – 54 mm long and consistently white petals that is restricted to a small area east of Swellendam between Suurbraak and Albertinia. We described the long-tubed form as the new subspecies P. dipetalum subsp. stenosiphon.Conclusion: The new subspecies increases our understanding of the diversity in P. dipetalum and represents a new taxon of conservation concern.

    education of AIDS prevention.Conclusion: Even in the high-prevalent areas of AIDS epidemic, women's perception on the situation of AIDS epidemic in China is not appropriate. Women know little about the three ways of AIDS transmission. They were lacking the awareness related to risk of infecting HIV. They did not know which contraceptive method could protect themselves from HIV infection. They also had misunderstanding and misconception regarding the condom use. Such factors mentioned above resulted in a low rate of condom use and an extremely low rate of consistent use of condom.The voluntary counseling and testing (VCT) was not sufficiently adopted in the high-risk population. The needs of AIDS prevention were great and unmet in the high HIV prevalent areas. People urgently hope that FPS network could play an important role in AIDS prevention.

  1. δ13CSC values of the loess-paleosol sequence in Dali area, Shaanxi Province, China, and paleoenvironmental implications

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    The carbon isotopic ratios of carbonate in the two profiles of the Dali area were analyzed and some new understandings on the influencing factors of the δ13CSC value of the loess-paleosol sequence and its paleoenvironmental implications were discussed preliminarily in this report. The 13CSC value of the Dali loess-paleosol sequence is synchronizing with the variance of magnetic susceptibility basically and the negative peaks of the δ13CSC curves are corresponding to the different developmental periods of the paleosol. It is believed that the intervention of the CO2 produced by plants will cause the decrease of the δ13CSC value, the amplitude of which may be relevant to the paleovegetation density and the ancient humidity. The relative biomass of C4 plants in the vegetation will affect the sublevel change of the δ13CSC. Low δ13CSC value by and large indicates the environmental conditions of the relatively abundant vegetation and humid climate. During the last 250000 years, the period with the sparsest vegetation and the most arid climate is the phase of the loess in L2 depositing and the period with the most abundant vegetation and the most humid climate is the last interglacial period. The δ13CSC curves of Dali also show that the High Temperature and Large Precipitation Event of the Qinghai-Tibetan Plateau during 40-30 kaBP had affected the Central Shaanxi Plain with relatively humid climate, and had apparent influence on the local vegetation and humidity.

    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. In carbon emission reduction, we should strict control land transformation to construction land, increase the energy efficiency of construction land, and avoid excessive development of forest land and water. In carbon sink increase, we should

    Full Text Available Background & objectives: Kahnooj district in south of Iran is an endemic area for malaria where Anophelesstephensi (Liston is a main malaria vector and An. dthali (Patton a secondary vector. According tothe national strategy plan on monitoring of insecticides resistance, this study was performed on susceptibilityand irritability levels of An. stephensi and An. dthali to different insecticides in the district.Methods: The susceptibility and irritability levels of field strains of An. stephensi and An. dthali at theadult and larval stages to discriminative dose of different imagicides was determined as recommendedby WHO.Results: Using discriminative dose and WHO criteria it was found that An. stephensi is resistant toDDT and dieldrin with 36.1 + 2.3 and 62.2 + 1.95 mortality rates, respectively; but susceptible to otherinsecticides. An. dthali was found to susceptible to all tested insecticides. The larvae of An. stephensi,exhibited 100% mortality for temephos and malathion, but 44 + 4.32 for discriminative dose offenitrothion. The results of irritability level for DDT and pyrethroids showed that permethrin had themost irritancy effect on An. stephensi and An. dthali. DDT and deltamethrin showed the least irritancyeffect against An. stephensi with 0.42 + 0.08 and 0.77 + 0.12 take-offs/min/adult, respectively, however,lambdacyhalothrin had the least irritancy effect against An. dthali with 0.096 + 0.02 take-offs/min/adult. The mean number of take-offs/min/adult with permethrin showed significant difference to DDT,lambdacyhalothrin, cyfluthrin and deltamethrin.Interpretation & conclusion: Pyrethroid insecticides are being used as indoor residual sprays in Iran.Based on our results, the main malaria vectors in the region are still susceptible to pyrethroid insecticides.Therefore, we propose the use of pyrethroids with low irritancy effect in rotation with carbamateinsecticides in two interval seasonal peaks of malaria transmission.

    About 16,000 km of multichannel seismic (MCS), gravity and magnetic data and 28 sonobuoys were acquired in the Riiser-Larsen Sea Basin and across the Gunnerus and Astrid Ridges, to study their crustal structure. The study area has contrasting basement morphologies and crustal thicknesses. The crust ranges in thickness from about 35 km under the Riiser-Larsen Sea shelf, 26 28 km under the Gunnerus Ridge, 12 17 km under the Astrid Ridge, and 9.5 10 km under the deep-water basin. A 50-km-wide block with increased density and magnetization is modeled from potential field data in the upper crust of the inshore zone and is interpreted as associated with emplacement of mafic intrusions into the continental margin of the southern Riiser-Larsen Sea. In addition to previously mapped seafloor spreading magnetic anomalies in the western Riiser-Larsen Sea, a linear succession from M2 to M16 is identified in the eastern Riiser-Larsen Sea. In the southwestern Riiser-Larsen Sea, a symmetric succession from M24B to 24n with the central anomaly M23 is recognized. This succession is obliquely truncated by younger lineation M22 M22n. It is proposed that seafloor spreading stopped at about M23 time and reoriented to the M22 opening direction. The seismic stratigraphy model of the Riiser-Larsen Sea includes five reflecting horizons that bound six seismic units. Ages of seismic units are determined from onlap geometry to magnetically dated oceanic basement and from tracing horizons to other parts of the southern Indian Ocean. The seaward edge of stretched and attenuated continental crust in the southern Riiser-Larsen Sea and the landward edge of unequivocal oceanic crust are mapped based on structural and geophysical characteristics. In the eastern Riiser-Larsen Sea the boundary between oceanic and stretched continental crust is better defined and is interpreted as a strike-slip fault lying along a sheared margin.

    Full Text Available A 12-month study was conducted in 4 communal grazing areas in the Bushbuckridge region, Limpopo Province, South Africa. The main objective was to investigate the impact of reduced acaricide application on endemic stability to bovine babesiosis (Babesia bigemina and Babesia bovis and anaplasmosis (Anaplasma marginale in the local cattle population. To this end 60 cattle in each communal grazing area were bled at the beginning and the conclusion of the experimental period and their sera were assayed for B. bovis, B. bigemina and Anaplasma antibodies. Cattle in the intensively dipped group were dipped 26 times and maintained on a 14-day dipping interval throughout the study, whereas cattle in the strategically dipped group were dipped only 13 times. Three cattle, from which adult ticks were collected, were selected from each village, while immature ticks were collected by drag-sampling the surrounding vegetation. During the dipping process, a questionnaire aimed at assessing the prevalence of clinical cases of tick-borne disease, abscesses and mortalities was completed by an Animal Health Technician at each diptank. An increase in seroprevalence to B. bovis and B. bigemina and a decrease in seroprevalence to Anaplasma was detected in the strategically dipped group while in the intensively dipped group the converse was true. Amblyomma hebraeum was the most numerous tick species on the cattle, and Rhipicephalus (Boophilus microplus was more plentiful than Rhipicephalus (Boophilus decoloratus. Drag samples yielded more immature stages of A. hebraeum than of Rhipicephalus (Boophilus spp. The incidence of clinical cases of tick-borne disease and of abscesses increased in the strategically dipped group at the start of the survey.

    Full Text Available The Mandan and Deh-Now bauxite deposits are located 40 km northeast of Dehdasht in Kohgiloye and Boyer-Ahmad province in the Zagros simply folded belt. The deposits were formed in the oldest rocks of the area of late Cretaceous age. The bauxite horizon is situated between Sarvak and Ilam formations. The aim of this study is to determine the mineralogy and texture relations of the deposits in order to determine the environment and status of bauxite mineralization. In this way, samples were selected from these bauxite deposits for mineralogical studies based on microscopic and XRD techniques. The bauxite horizon in the Mandan deposit consists of white, gray, black, pisolitic, red and yellow bauxites. The sequence was repeated in the Deh-Now without black and gray bauxites. Mineralogy is similar in all bauxitic layers and the main textures are pisolitic-ooide, ooide-spheroid, pisolitic, pelitomorphic and pseoudomorphic. Bohmite, diaspore, kaolinite and calcite are the most important minerals in both bauxitic layers of the Mandan and Deh-Now deposits. Due to bohmite mineralization in the study area, erosional and intense weathering environment in the Touronian-Cenomanian could be suggested for the deposition of bauxite in these deposits. Existence of interclasts in the pisolites and ooides indicate that these bauxites were transformed from the primary in situ environment to karstic sedimentary basin as authigenic origin. These studies indicate that there are two mineralized facies with different environmental status: (1 oxidation facies with bohmite, diaspore, kaolinite and hematite minerals and (2 reduced facies with pyrite, diaspore and chlorite mineralization. The lack of reduced condition at the Deh-Now deposit shows that the deposit formed only in oxidation status.

    In current selective sequential extraction (SSE) methods, heavy metals associated well-crystallized iron oxyhydroxides are not well defined and considered, and usually fall into residual forms, which actually make their mobility and environmental risk underestimated. This study compared various fractions of heavy metals in samples of mining tailings and nearby soils under different land uses in Guangdong Province of China. Iron oxides in these soils were mainly Al-substituted goethites and/or hematites. Independent of the land uses, the percentages of various Cd fractions in the soils decrease in the order of well-crystallized iron oxyhydroxides-associated (27.2-91.2%) > residual (2.1-37.0%) > reducible FeMn oxides (3.2-45.7%) > exchangeable (1.0-28.2%) > organic-associated form (0-5.1%). Pb mainly existes in the residual fraction (25.9-74.5%), followed by crystalline iron oxyhydroxides-associated (0.4-69.0%) and reducible fractions (2.4-40.4%). Zn mainly exists in the residual fraction (25.4-85.9%), followed by the well-crystallized iron oxyhydroxides-associated fraction (6.4-55.0%). However, Cu mainly existes in the residual form and the fractionation of Cu varies obviously between samples. The association of these metals with crystalline iron oxyhydroxides in the soils decreases in the sequence of Cd > Pb > Zn > Cu. These results suggest that in heavy-metal-polluted weathered soils in tropical and subtropical areas enriched with iron oxides, it is essential to assess potential bioavailability and toxicity of heavy metals bound to well-crystallized iron oxyhydroxides with appropriate procedures in the fractionation measurement. The modified Tessier method present here can be used to quantify the fractions of heavy metals in such areas. PMID:27427775

  10. Characteristics and origins of primary fluids and noble gases in mantle-derived minerals from the Yishu area,Shandong Province, China

    2006-01-01

    Fluids and noble gases of mantle-derived materials are important tracers for the mantle information. Compositions of primary fluids and noble gases in mantle-derived minerals from the Yishu area, Shandong Province, China, were tested by the methods of heat-bursting and heat-melting respectively. The fluids are mainly composed of CO2, CO and H2, which account for about 90% of the total, and are similar to the mantle-derived rocks from other areas of eastern China; ratios of 3He/4He in almost all samples range from 0.82 Ra to 2.74 Ra, whereas 40Ar/36Ar from 299.5 to 758.8. Both ranges are much lower than those of the typical ocean mantle-derived samples (such as MORB) and primarily reflect the influences of the atmospheric components and the radiogenic isotopes. Ratios of C/3He range from 27.6×109 to 1050×109, N2/Ar from 927 to 56612, and N2/3He from 2.5×109 to 27×109, similar to those in western United States and New Zealand which belong to the tectonic plate collision regions. The ratios fall in the intersect of mantle-crust-atmosphere in the comprehensive tracer-charts, reflecting the influences of the atmosphere and the crusts with organic components. Our results suggest that the composition of the primary fluids and the isotopic ratios of the noble gases may either reflect the evolution process of mantle-derived rocks connected with the rise and eruption of magma, or the influence of the ancient subduction-plate on the continental mantle of this region.

    Full Text Available BACKGROUND: Access to health care is a major requirement in improving health and fostering socioeconomic development. In the People's Republic of China (P.R. China, considerable changes have occurred in the social, economic, and health systems with a shift from a centrally planned to a socialist market economy. This brought about great benefits and new challenges, particularly for vertical disease control programs, including schistosomiasis. We explored systemic barriers in access to equitable and effective control of schistosomiasis. METHODOLOGY: Between August 2002 and February 2003, 66 interviews with staff from anti-schistosomiasis control stations and six focus group discussions with health personnel were conducted in the Dongting Lake area, Hunan Province. Additionally, 79 patients with advanced schistosomiasis japonica were interviewed. The health access livelihood framework was utilized to examine availability, accessibility, affordability, adequacy, and acceptability of schistosomiasis-related health care. PRINCIPAL FINDINGS: We found sufficient availability of infrastructure and human resources at most control stations. Many patients with advanced schistosomiasis resided in non-endemic or moderately endemic areas, however, with poor accessibility to disease-specific knowledge and specialized health services. Moreover, none of the patients interviewed had any form of health insurance, resulting in high out-of-pocket expenditure or unaffordable care. Reports on the adequacy and acceptability of care were mixed. CONCLUSIONS/SIGNIFICANCE: There is a need to strengthen health awareness and schistosomiasis surveillance in post-transmission control settings, as well as to reduce diagnostic and treatment costs. Further studies are needed to gain a multi-layered, in-depth understanding of remaining barriers, so that the ultimate goal of schistosomiasis elimination in P.R. China can be reached.

    The Huashixia area in the Madoi County, Qinghai Province, western China is one of the most important areas for the studies of the formation and evolution of the A’nyemaqen mélange zone due to the well exposed, relatively complete tectonostratigraphic successions. However, the timing and evolu-tionary process of the A’nyemaqen paleo-ocean has long been poorly understood. Recently, we obtained abundant radiolarians from the siliceous rocks of the Maerzheng Formation of this mélange zone in Huashixia. Total 19 species in 10 radiolarian genera have been identified. They belong mainly to the Al-baillellaria, Spumellaria, Entactinaria, and Latentifistularia. Four radiolarian assemblage zones are es-tablished, including: thePseudoalbaillella rhombothoracata,Pseudoalbaillella scalprata,Ruzhencevispongus uralicus,andFollicucullus bipartitus-Follicucullussp. cf.F. ventricosus zones. Radiolarian faunal correla-tions suggest a late Artinskian–early Kungurian age and late Capitanian–early Wuchiapingian age for the first two zones from the lower part and the last two zones from the upper parts of the Maerzheng Forma-tion, respectively. All radiolarians are typical of deep water elements living in deep oceans in low latitudes during the Permian. Previously, the radiolarians of Early Carboniferous to Early Permian age and fusu-linids of Early–Middle Permian age have also been reported from the A’nyemaqen mélange successions. The combination of the newly found radiolarians with the previously reported faunal and microfloral as-semblages as well as radiometric ages obtained from the same stratigraphic units indicates that the A’nyemaqen paleo-ocean may have opened initially during the Early Carboniferous, expanded from the Early–Middle Permian, reached its acme in the early Late Permian, shrunk during the latest Permian to Early Triassic, and eventually was closed in the Middle Triassic.

    The adaptation and survive of introduced plants to local well brine groundwater irrigation is an important issue, while people introduce some plants to improve the local environment in the construction of urban greening oases in arid areas, north China. We measured some of the photosynthetic characteristics of introduced Bamboo willow irrigated by different local well brine groundwater in the wild controlled experiments, in May 2014 in Kelamayi city in north China, which to seek the most appropriate irrigation concentration of underground saline water, and to clarify the physiological ecological adaptation to the local habitat. The parameters, measured by Li-6400XT, a portable photosynthesis system, include the following ones, net photosynthetic rate (Pn), stomatal conductance (Gs), transpiration rate (Tr), the internal CO2 concentration (Ci) and efficiency of water application (WUE) of one-year old introduced Bamboo willow irrigated by set salinity groundwater gradient, as 0 g/L, 5 g/L and 10 g/L. the results showed that (1) In each salt water concentration, the diurnal variation curve of net photosynthetic rate showed as "bimodal curve" style, and obvious "midday depression". (2) The parameter Pn of Bamboo willow irrigated by salt water of 5g/L was highest compared with the other two, and the value Pn irrigated by salt water concentration of 10g/L down. The net photosynthetic rate would increase in the salt concentration of 10g/L. In conclusion, the salt groundwater concentration of 10g/L was the optimal concentration of local well brine groundwater irrigation for Bamboo willow introduced to the arid areas in northern Xinjiang province, China.

    Landslides are identified as one of the most important natural hazards in many areas throughout the world. The essential purpose of this study is to compare general linear model (GLM), general additive model (GAM), multivariate adaptive regression spline (MARS), and modified analytical hierarchy process (M-AHP) models and assessment of their performances for landslide susceptibility modeling in the west of Mazandaran Province, Iran. First, landslides were identified by interpreting aerial photographs, and extensive field works. In total, 153 landslides were identified in the study area. Among these, 105 landslides were randomly selected as training data (i.e. used in the models training) and the remaining 48 (30 %) cases were used for the validation (i.e. used in the models validation). Afterward, based on a deep literature review on 220 scientific papers (period between 2005 and 2012), eleven conditioning factors including lithology, land use, distance from rivers, distance from roads, distance from faults, slope angle, slope aspect, altitude, topographic wetness index (TWI), plan curvature, and profile curvature were selected. The Certainty Factor (CF) model was used for managing uncertainty in rule-based systems and evaluation of the correlation between the dependent (landslides) and independent variables. Finally, the landslide susceptibility zonation was produced using GLM, GAM, MARS, and M-AHP models. For evaluation of the models, the area under the curve (AUC) method was used and both success and prediction rate curves were calculated. The evaluation of models for GLM, GAM, and MARS showed 90.50, 88.90, and 82.10 % for training data and 77.52, 70.49, and 78.17 % for validation data, respectively. Furthermore, The AUC value of the produced landslide susceptibility map using M-AHP showed a training value of 77.82 % and validation value of 82.77 % accuracy. Based on the overall assessments, the proposed approaches showed reasonable results for landslide

    That area in the Province of Salta at North West of Argentina has a size not smaller than Belgium and low growing population, and is a specific example of combined natural, ecologic, agricultural and human evolution, where a main restriction is the necessity to avoid desertification, that is the soil quality loss studied now in several forums, the U.N.O. having said "Desertification has a very high incidence in the environmental and food security, socioeconomic stability and world sustained development". It is one of FAO's most important preoccupations as hunger in the world is increasing. Multiple factors are involved on it. Ones are in relation with natural phenomena like water and wind erosion. Others with human activities linked to soil use and water management, and finally with inappropriate activities. The parallel 24° S is central and sun is intense, annual rain is between 1000mm to 600mm being lower at East, and climate is agreable for humans specially at dry season from May to November. The soils came mostly as large deposits from rivers, from Andes Mountains, the large study area is rather flat with low mountains at SW, otherwise altitude is from 500m at NW to 200 at SE. The Bermejo is the greater river and at cross from NW to SE and has elevated land and consequently has migrated 50-100 km to NE letting a smaller channel in previous course. The city of Salta is out at West, organized since about 1588, and a main road runs N-S at the higher West of the area communicating it with Salta and towards distant Rio de la Plata for commerce, and with Bolivia at Nord. The use of land changes from West, which is now intensely cultivated and uses somewhere water from rivers, to East were the Wichi Indians live primitively and freely in a very large natural area using goats and "chanchos" (pigs) of European origin that grow in big numbers undomesticated, having somehow degraded original natural vegetation that contains now specific shrubs and small trees in areas

    A quasi-experimental study was conducted to develop a health education modification program based on self-efficacy and motivation regarding liver flukes and cholangiocarcinoma development in Keang Sanam Nang district, Nakhon Ratchasima province, Thailand. A total of 36 individuals were invited to participate in the program and were screened for population at risk of liver fluke infection and cholangiocarcinoma using SUT-OV-001 and SUT-CCA-001. Development of health education modification program regarding liver fluke and cholangiocarcinoma prevention included 3 steps: (1) preparation, (2) health education program, and (3) follow-up and evaluation. The study was implemented for 10 weeks. Pre-and-post-test knowledge was measured with questionnaires, Kuder-Richardson-20: KR-20 = 0.718,and Cronbach's Alpha Coefficient = 0.724 and 0.716 for perception and outcome expectation questionnaires. Paired and independent t-tests were applied for data analysis. The majority of the participants were female (55.6%), aged between ≤50 and 60 years old (36.1%), married (86.1%), education level of primary school (63.9%), agricultural occupation (80.6%), and income <4,000 Baht (44.4%). The results revealed that after the health education program, the experimental group had a mean score of knowledge, perception, and outcome expectation regarding liver fluke and cholangiocarcinoma prevention significantly higher than before participation and in the control group. In conclusion, this successful health education modification program for liver fluke and cholangiocarcinoma, therefore may useful for further work behavior modification in other epidemic areas.

    Full Text Available Human populations throughout much of the world are experiencing unprecedented changes in their relationship to the environment and their interactions with the animals with which so many humans are intimately dependent upon. These changes result not only from human induced changes in the climate, but also from population demographic changes due to wars, social unrest, behavioral changes resulting from cultural mixing, and large changes in land-use practices. Each of these social shifts can affect the maintenance and emergence of arthropod vectors disease or the pathogenic organisms themselves. A good example is the country of Pakistan, with a large rural population and developing urban economy, it also maintains a wide diversity of entomological disease vectors, including biting flies, mosquitoes, and ticks. Pathogens endemic to the region include the agents of piroplasmosis, rickettsiosis, spirocheteosis, and viral hemorrhagic fevers and encephalitis. The northwestern region of the country, including the Khyber Pakhtunkhwa Province (KPK, formerly the North-West Frontier Provence (NWFP, and the Federally Administered Tribal Areas (FATA are mountainous regions with a high degree of habitat diversity that has recently undergone a massive increase in human population density due to an immigrating refugee population from neighboring war-torn Afghanistan. Vector-borne diseases in people and livestock are common in KPK and FATA regions due to the limited use of vector control measures and access to livestock vaccines. The vast majority of people in this region live in abject poverty with >70% of the population living directly from production gained in animal husbandry. In many instances whole families live directly alongside their animal counterparts. In addition, there is little to no awareness of the threat posed by ticks and transmission of either zoonotic or veterinary pathogens.

    Full Text Available The study area is located at northwest of Sarbisheh in South Khorasan province and eastern border of Lut block. In this area, Tertiary (Eocene-Oligocene to Pliocene volcanic rocks consisting of basaltic andesite, dacite, rhyodacite, vitreous rhyolite (perlitic in some parts, tuff and ignimbrite are exposed. In the Daghar Mountain, A, B and C perlite layers with thicknesses of 102, 7 and 58 meters respectively, occur alternatively with volcanic-pyroclastic rocks. Zoning, sieve texture and embayment of plagioclase and roundness of minerals in the lavas indicate disequilibrium conditions during magma crystallization. Chemically, these are meta-aluminous, medium to high-K calc-alkaline, enriched in LILE and negative anomaly for Nb and Ti. Chondrite-normalized Rare Earth Elements (REE plots indicate enrichment of light REE in comparison with heavy REE, (La/YbN of 9.14-12.64, low negative anomaly for Eu in basaltic andesite (Eu/Eu*=0.91 and dacite (Eu/Eu*=0.78-0.87 and strong negative anomaly for Eu in the rhyolites (Eu/Eu*=0.18-0.35. Negative anomaly for Eu indicates calc-alkaline nature for these rocks. On the basis of chemical characteristics and magnetic susceptibility, these are I-type. Tectonically, the rocks belong to subduction zone and active continental margin and their parental magma originated from partial melting of enriched mantle and then crustal contamination during differentiation process. Dacites have an initial 87Sr/86Sr between 0.7048 and 0.7050 (average 0.7049 that confirm mantle source for the magma.

    Contaminated food through dietary intake has become the main potential risk impacts on human health. This study investigated concentrations of rare earth elements (REEs) in soil, vegetables, human hair and blood, and assessed human health risk through vegetables consumption in the vicinity of a large-scale mining area located in Hetian Town of Changting County, Fujian Province, Southeast China. The results of the study included the following mean concentrations for total and bio-available REEs of 242.92 ± 68.98 (135.85-327.56)μg g(-1) and 118.59 ± 38.49 (57.89-158.96)μg g(-1) dry weight (dw) in agricultural soil, respectively, and total REEs of 3.58 ± 5.28 (0.07-64.42)μg g(-1) dw in vegetable samples. Concentrations of total REEs in blood and hair collected from the local residents ranged from 424.76 to 1274.80 μg L(-1) with an average of 689.74 ± 254.25 μg L(-1) and from 0.06 to 1.59 μg g(-1) with an average of 0.48 ± 0.59 μg g(-1) of the study, respectively. In addition, a significant correlation was observed between REEs in blood and corresponding soil samples (R(2)=0.6556, p0.05). Mean concentrations of REEs of 2.85 (0.59-10.24)μg L(-1) in well water from the local households was 53-fold than that in the drinking water of Fuzhou city (0.054 μg L(-1)). The health risk assessment indicated that vegetable consumption would not result in exceeding the safe values of estimate daily intake (EDI) REEs (100-110 μg kg(-1)d(-1)) for adults and children, but attention should be paid to monitoring human beings health in such rare earth mining areas due to long-term exposure to high dose REEs from food consumptions.

    Obvious differences in mineralization characteristics exist between the southern and northern parts of the eastern part of the Jiangnan Uplift in northern Jiangxi Province and southern Anhui Province. The regional metallogeny is discussed, and the ore-forming fluid systems are classified in this article. It is proposed that the fluid ore-forming activities in the Jiangnan Uplift both in northern Jiangxi and southern Anhui have close relationships with the crustmantle interaction and magmatic-tectonic activities. The types and scales of the mineralization on the both sides of the eastern Jiangnan Uplift were determined by fluid ore-forming systems and geological backgrounds.

    Full Text Available The Norite Koppies Bushveld vegetation type boasts a distinctive and contrasting topography and species composition easily distinguished from that of surrounding areas. A phytosociological study was done on the leased mining area of the Impala Platinum Mining Company north of Rustenburg in the North-West Province. Similar norite koppies, situated west of the Norite Koppies Bushveld vegetation, and not yet mapped by Mucina & Rutherford (2006, were identified in the study area and phytosociologically described. Six plant communities and two subcommunities were identified. Multivariate statistical analyses (correspondence analyses confirmed that the species composition of these areas corresponds with and does therefore form part of the Norite Koppies Bushveld vegetation type as described by Mucina & Rutherford (2006. Some of these communities contain Boscia albitrunca, a protected plant species, and should therefore be considered as areas with conservation value.

    Human populations throughout much of the world are experiencing unprecedented changes in their relationship to the environment and their interactions with the animals with which so many humans are intimately dependent upon. These changes result not only from human induced changes in the climate, but also from population demographic changes due to wars, social unrest, behavioral changes resulting from cultural mixing, and large changes in land-use practices. Each of these social shifts can affect the maintenance and emergence of arthropod vectors disease or the pathogenic organisms themselves. A good example is the country of Pakistan, with a large rural population and developing urban economy, it also maintains a wide diversity of entomological disease vectors, including biting flies, mosquitoes, and ticks. Pathogens endemic to the region include the agents of piroplasmosis, rickettsiosis, spirochetosis, and viral hemorrhagic fevers and encephalitis. The northwestern region of the country, including the Khyber Pakhtunkhwa Province (KPK), formerly the North-West Frontier Provence (NWFP), and the Federally Administered Tribal Areas (FATA) are mountainous regions with a high degree of habitat diversity that has recently undergone a massive increase in human population density due to an immigrating refugee population from neighboring war-torn Afghanistan. Vector-borne diseases in people and livestock are common in KPK and FATA regions due to the limited use of vector control measures and access to livestock vaccines. The vast majority of people in this region live in abject poverty with >70% of the population living directly from production gained in animal husbandry. In many instances whole families live directly alongside their animal counterparts. In addition, there is little to no awareness of the threat posed by ticks and transmission of either zoonotic or veterinary pathogens.

    The Zhelin Bay is one of the most important bays for large-scale maricuhure in Guangdong Province,China.Owing to the increas-ing human population and the expanding marieuhure in the last two decades,the ecological environment has greatly changed with frequent harmful algal blooms.A monthly survey of water content,organic matter ( TOM ),and various forms of nitrogen and phosphorous in sediment from July 2002 to July 2003 in the bay was conducted.The results showed that the water content was cor-related significantly with TOM and various forms of nitrogen and phosphorus and can be used as proxy for quick and rough estimate of these factors in the future surveys.TOM was also correlated significantly with various forms of nitrogen and phosphorus,indica-ting that it was one of the key factors affecting the concentrations and distributions of nitrogen and phosphorus in the investigated waters. Average total Kjeldhal nitrogen (TkN) Content was( 1113.1±382.5 )μg/g and average total phosphorus (TP) content was(567.2 ± 223.3)μg/g, and both were much higher than those of similar estuaries in China and elsewhere. Average nitrogen and phosphorus tended to be higher inside than outside the bay,higher at aquaculture than non-aquacuhure areas,and higher at fish-cage culture than oyster culture areas,suggesting that large-scale mariculture inside the bay played an important role in the eutrophication of the Zhelin Bay.Various forms of nitrogen and phosphorus concentrations were higher during the warm season (July--September),which was due to the increased decomposition and concentration of organic matter resulted from the fast growth and high mortality of the cultured species.Compared with July 2002,TkN and TP contents were much higher in July 2003,in consonance with the eut~'ophication of the Zhelin Bay.Because exchangeable phosphorus ( Ex-P),iron-bounded phos-phorus (Fe-P) and organic phosphorus (OP) combined accounted for 34.3% of the TP and authigenie phosphorus (Au-P) ac

    Measles surveillance in Jiangsu Province started in 1999 by dividing the province into two sorts of areas. The first sort of area is economic well-developed area where EPI is carried out well and measles incidence is lower. The cities of this area investigated included Suzhou, Wuxi, Changzhou and Zhenjiang. The second sort of area included 9 cities (Nanjing, Xuzhou, Liangyungang, Nantong, Huaiyin, Suqian, Yangcheng, Yangzhou and Taizhou) where all the conditions are not as good as that mentioned in the first sort of area. The surveillance system of the province reported in 1999 a total of 938 suspected measles cases in 13 cities, of which 684 were confirmed as measles. The notifiable reporting system reported 846 suspected measles cases and 684 cases were confirmed. This indicated that the surveillance system operated well. The measles epidemiological features in two sorts of areas were compared. In first sort of area, including Nanjing, the measles cases of ≥15 years old accounted for 66.3% of the total cases. In second sort of area, not including Nanjing, the measles cases of <15 years old accounted for 90.8% of the total cases, and 73.2% of them were patients <10 years old. In 1999, there were 10 measles outbreaks occurred in the province and 218 measles cases were reported which accounted for 31.7% of the confirmed measles cases reported by the provincial measles surveillance system. 9% the 10 outbreaks occurred in the second sort of area, the cases were preschool and primary school children. The results showed that progression of EPI work was uneven in two sorts of areas of Jiangsu Province.%江苏省在1999年分两类地区开展了麻疹监测,一类地区为经济较发达、计划免疫工作基础好、麻疹发病水平较低的苏州等4个市;而以南京、徐州等9个市为二类地区。全年麻疹监测系统报告疑似麻疹938例,而法定传染病常规报告系统报告846例,前者比后者多92例。对两类地区麻疹发病

    Full Text Available Abstract Background The first 18 months of life are the most important for long-term childhood well-being. Anemia and malnutrition occurring in this key period have serious implications for individuals and societies, especially in rural areas in developing country. We conducted a cross-sectional study as the baseline survey to provide data for developing a policy-based approach to controlling infant anemia and malnutrition in rural areas of Shaanxi province in northwestern China. Methods We randomly sampled 336 infants aged 0–18 months in 28 rural villages from 2 counties of Shaanxi province. Anthropometric measurements and household interviews were carried out by well-trained researchers. The hemoglobin concentration was measured for 336 infants and serum concentrations of iron, zinc, and retinol (vitamin A were measured for a stratified subsample of 55 infants. Anemia was defined using World Health Organization (WHO standards combined with the Chinese standard for infants Results We found that 35.12% of infants in rural Shaanxi suffered from anemia, and the malnutrition prevalence rates were 32.14% for underweight, 39.58% for stunting, and 11.31% for wasting. Anemia was significantly associated with malnutrition (underweight, OR: 2.42, 95%CI: 1.50-3.88; stunting, OR: 1.65, 95%CI: 1.05-2.61; wasting, OR: 2.89, 95%CI: 1.45-5.76. Low birth weight, more siblings, less maternal education, low family income, crowded living conditions, and inappropriate complementary food introduction significantly increased the risk for infant anemia. Serum concentrations of iron, zinc, and retinol (vitamin A were significantly lower in anemic infants compared with non-anemic infants. Conclusions Specific socio-demographic characteristics and feeding patterns were highly associated with infant anemia in rural areas of Shaanxi province. Health education focusing on feeding practices and nutrition education could be a practical strategy for preventing anemia and

  18. The prevalence of Epstein-Barr virus infection in head and neck non-Hodgkin's lymphomas in Khorasan, northeast of Iran

    International Nuclear Information System (INIS)

    Objectives: To investigate the frequency and possible role of Epstein-Barr virus infection in non-Hodgkin's lymphomas of the oral cavity and maxillofacial region in Khorasan (Northeast of Iran). Methods: The cross-sectional retrospective study assessed the frequency of Epstein-Barr virus infection in non-immunosuppressed non-Hodgkin's lymphoma cases of the oral cavity and maxillofacial region. Formalin-fixed, paraffin-embedded tissue sections from 34 cases of head and neck non-Hodgkin's lymphoma (17 low-grade B-cell lymphoma, 14 diffuse large B-cell lymphoma, and 3 peripheral T cell lymphoma) were selected as a case group, and 10 normal lymph node sections were considered as a control group. Polymerase chain reaction was used to detect the EBV-DNA in tissue specimens. SPSS 16 was used for statistical analysis of the data. Results: EBV-DNA was detected in 26.5% of NHL samples. Among NHLs, Epstein-Barr virus was found to be positive in 50% cases with diffuse large B-cell lymphoma and 11.8% of low grade B-cell lymphomas. Epstein-Barr virus was not detected in any cases of peripheral T-cell lymphoma. Conclusion: Although it seems that Epstein-Barr virus appears to be an etiological factor in some subtypes of non-Hodgkin's lymphomas, especially in diffuse large B-cell lymphoma, more researches should be done to investigate the relationship between Epstein-Barr virus infection and head and neck non-Hodgkin's lymphomas.

  19. Granite, gabbro and mafic microgranular enclaves in the Gejiu area, Yunnan Province, China: a case of two-stage mixing of crust- and mantle-derived magmas

    2012-10-01

    Geochronological, geochemical, whole-rock Sr-Nd, and zircon Hf isotopic analyses were carried out on the Jiasha Gabbro, mafic microgranular enclaves (MME) and host Longchahe Granite samples from the Gejiu area in the southeast Yunnan province, SW China, with the aim of characterizing their petrogenesis. Compositional zoning is evident in the gabbro body as the cumulate textures and mineral proportions in the gabbro interior are distinct from the gabbro margin. The Longchahe Granite largely comprises metaluminous quartz monzonite with distinctive K-feldspar megacrysts, but also contains a minor component of peraluminous leucogranite. The MME have spheroidal to elongated/lenticular shapes with sharp, crenulated and occasionally diffuse contacts with the host granite, which we attribute to the undercooling and disaggregation of mafic magma globules within the cooler host felsic magma. Field observations, geochronology, geochemistry, Sr-Nd and zircon Hf isotopic compositions point to a complex petrogenesis for this granite-MME-gabbro association. Zircon 206Pb/238U ages determined by LA-ICP-MS for a mafic enclave, its host granite and the gabbro body are 83.1 ± 0.9 Ma, 83.1 ± 0.4 Ma and 83.2 ± 0.4 Ma, respectively, indicating coeval crystallization of these igneous rock units. Crystal fractionation processes can explain much of the compositional diversity of the Jiasha Gabbro. The geochemical features of the gabbro, such as high Mg# (up to 70) and Cr (up to 327 ppm), enrichment in LILEs (e.g., Rb, Ba, K2O) and LREEs, and depletion in HFSE (e.g., Nb, Ta, Ti), together with initial 87Sr/86Sr ratios of 0.708-0.709 and negative ɛNd(t) values (-5.23 to -6.45), indicate they were derived from a mantle source that had undergone previous enrichment, possibly by subduction components. The Longchahe Granite has a large range of SiO2 (59.87-74.94 wt%), is distinctly alkaline in composition, and has Sr-Nd-Hf isotopic compositions ((87Sr/86Sr)i > 0.712, ɛNd(t) = -6.93 to -7

    湖北省农村劳动力绝大部分向省外转移,省际转移呈现不均衡现象,其中又以东部和中等城市转移为主.从经济学原因分析湖北省农村劳动转移地区分布的成因.结果表明:农民迁移决策是理性的,符合其收益的最大化.农村劳动力转移与地区经济发展水平紧密相关,转移对收入差距的弹性有增大的趋势,省际间经济和收入差距不断扩大,直接影响到农村劳动力的迁入量.农村劳动力转移除了受机会成本的影响,还受迁入地区生活成本、两地空间距离以及农民自身因素的影响.顺应劳动力转移规律和自身经济发展状况,湖北应注重中小城市的建设,大力发展劳动密集型企业和外向型企业,增强湖北经济实力,为湖北农村劳动力转移提供更多的就业机会和就业岗位.同时进行政策与制度创新,建立农村劳动力技能培训机制、社会保障机制、信息传导机制以及统筹城乡居民的管理机制等.%The majority of rural labor in Hubei province transfer to the outside of the province. The inter-provincial transfer showed an imbalance phenomenon, the rural labors in Hubei province mainly transferred to the middle cities in the eastern China. The causes for area distribution of rural labor in Hubei province were analyzed from economics. The results showed that farmers' immigration decision is rational, which accord with maximization of theirs income. The rural labor transfer related to the developmental level of regional economy. The transfer will increase the elasticity of income gap, and the increasing gap of economy and income between provinces will directly influences the move in amount of rural labors. Besides opportunity cost, the rural labor transfer is influenced by living cost in move in area, spatial distance between two places and self-factors of farmers. Therefore, in order to provide more employment opportunities and employment posts for the rural labor

En effet, les écosystèmes marins sont essentiels, d’autant plus, qu’ils présentent en Nouvelle-Calédonie une grande richesse, notamment en termes de patrimoine culturel. Ce sont majoritairement les Kanak qui habitent sur la Côte Est de la Province Nord, où la Collectivité et le WWF collaborent à la mise en place de plusieurs aires marines protégées (AMP. Jusqu’à présent, la gestion coutumière Kanak a permis une relative préservation de ces écosystèmes dans un secteur littoral non soumis aux pressions de l’urbanisation, du tourisme ou de la navigation. L’étude s’attache à souligner les enjeux autour de la mise en place des AMP et des perspectives de développement local, sur le milieu marin et les populations locales. Il s’agit de voir comment cette expérimentation est envisagée par les différents acteurs (État, Province Nord, associations, coutumiers etc. et de s’interroger sur les mécanismes de gouvernance.This study allows a distinct approach to thinking about the marine resources in a protected area.

    Objective: To examine the prevalence and clinical manifestations of cutaneous leish-maniasis (CL) in Iran. Methods: This study was conducted in Iran between 2011 and 2013. Sampling, pre-paring, developing, and fixing of suspicious skin lesions were completed in healthcare centers in 31 Iranian provinces as well as in the Academic Reference Laboratory and the National Reference Laboratory. The information was then analyzed at the Ministry of Health's Information Management Center of Contagious Diseases. Results: Over a three-year period, the number of people identified with CL was 56 546. The highest incidence was reported in 2011 (27.5 per 100 000). Wet CL accounted for 43.7% of cases while 43.3% resulted from sporotrichoid leishmaniasis. The results showed that there was a higher incidence of CL due to Leishmania major (50.2%) than to Leishmania tropica. The results of this study found that the highest incidence of CL had happened respectively in Ilam, Fars and, Khorasan Razavi Provinces between 2011 and 2013. Conclusions: Although the incidence of the disease is declining, CL is still a public health concern and disease control protocols need to be established. Therefore, further studies are needed to identify the vectors, reservoirs, and disease species as well as to develop appropriate disease control strategies.

    The aim of the study was to survey perceptions of quality of (primary) health care services provided in rural communities in the Limpopo province. Ten focus groups discussions were held with community members chosen by convenience from public places from four villages in the central region of the Limpopo Province. The sample included 42 women and 34 men (76 participants). Results indicated perceived quality discussed within the following categories: (1) conduct of staff (reception, communication, discrimination, care and compassion, respect for privacy), (2) technical care (examination, explanation of treatment, responsiveness, treatment outcomes), (3) health care facility, (4) health care organisation, (5) drugs (availability, explanation, effectiveness, payment), and (6) waiting time. The findings suggest some satisfaction with free basic and preventive health care and social services provided but there is a need to look closely into the interpersonal dimension of the services provided, provision of medication with adequate explanation to patients on the medication given, and on structural aspects, there is need for the government to give support to the clinics to provide adequate services. Improving drug availability, interpersonal skills (including attitudes towards patients) and technical care have been identified as the three main priorities for enhancing perceived quality of primary health care and health policy action.

    Based on cross-dating tree rings from the Tianmu Mountain, Zhejiang Province, the tree rings α-cellulose δ 13C time series was measured. By spectrum analysis, the variation of tree-ring δ13C sequence shows a quasi periodicity of 4.4 years, which is coincident with the standard cycle of El Nino. After removing the long-term decrease trend of the δ13C variation related to atmospheric CO2 concentration, the response of the δ13C to climate elements was analyzed using meteorology data from a nearby weather station. The results suggest that there is a distinct relativity between high-frequency variation of tree ring δ 13C series and seasonal climate parameters, e.g. Temperature and precipitation, with a significant time-lag effect. In addition, the high frequency also reflects the strength change of the East Asian Monsoon. The multiple regression method was employed to reconstruct the historical climate, and to analyze the climate change and trend in the last 160 years in the northern Zhejiang Province.

    Full Text Available Background and Objectives:  Iranian chronic HBV carrier’s population has shown a unique pattern of genotype D distri- bution all around the country. The aim of this study was to explore more details of evolutionary history of carriers based on structural surface proteins from different provinces.Materials and Methods: Sera obtained from 360 isolates from 12 Different regions of country were used for amplificationand sequencing of surface proteins. A detailed mutational analysis was undertaken.Results: The total ratio for Missense/Silent nucleotide substitutions was 0.96. Sistan and Kermanshah showed the lowest rate of evolution between provinces (P = 0.055. On the other hand, Khorasan Razavi and Khoozestan contained the highest ratio (P = 0.055. The rest of regions were laid between these two extremes. Azarbayjan and Guilan showed the highest proportion of immune epitope distribution (91.3% and 96%, respectively. Conversely, Sistan and Tehran harbored the least percentage (66.6% and 68.8%, respectively. Kermanshah province contained only 5.2%, whereas Isfahan had 54.5% of B cell epitope distribution. In terms of T helper epitopes, all provinces showed a somehow homogeneity: 22.58% (Fars to 46.6% (Khuz- estan. On the other hand, distribution of substitutions within the CTL epitopes showed a wide range of variation between 6.6% (Khuzestan and 63% (Kermanshah.Conclusion: Further to low selection pressure found in Iranian population, the variations between different regions designate random genetic drift within the surface proteins. These finding would have some applications in terms of specific antiviral regimen, design of more efficient vaccine and public health issues.

    To determine the crustal stress field based on the basis of earthquake waves, we analyze data from fixed seismic stations in Gansu and surrounding provinces and the broadband portable seismic array in southeast Gansu province, where three blocks converge to create complex tectonic conditions. Two methods used to directly obtain such stress fields include those based on focal mechanism data and p-wave first motion data. In order effectively use small and microscale earthquake data, the latter method is used in our study. On the basis of near earthquake observation data recorded from November 1, 2010, to November 30, 2011, we use Zhang's Method to relocate earthquakes occurring in this area. As a result, 2 379 earthquakes and 12 129 p-wave polarity data are obtained through which the directions of principal stress axes are inferred. The inversion method and program are provided by Wan. Our study assumes a relative stress value of 0. 5. We calculate only the 2-D stress field because most earthquakes have occurred in the research area at depths of 5~20 km; the average depth of 12 km was chosen as the calculating depth. The direction of tectonic stress field in a 0.25°×0.25 grid in this area is presented for the first time. The orientation of P, B, and T axis azimuths are obtained by 1° × 1° × 1° grid searching. We treat these azimuths as stress flied directions when the contradictory ratio is the smallest. Results show that the maximum compressive stress axis strikes are presented in a radiated pattern; that is, they strike east-west from NEE in northern part to SEE in the east. These findings are similar to that reported in previous research, through which we can infer that the Qinghai -Tibet plateau moving to the northeast encountered the stable Ordos block and the South China block moving to the southeast; thus, the material moved southeast. The earthquakes occurring in this region were fewer and smaller than those west of 104° E; therefore, the stress field

    Gentile di maiale is a typical meat product prepared in some traditional plants of Latina Province (Central Italy). It is obtained from dehydration, salting, smoking and ripening of swine rectum. Aim of this study was to evaluate the influence of the traditional smoking process on polycyclic aromatic hydrocarbons (PAHs) content by means of high-performance liquid chromatographic/fluorescence detection. Polycyclic aromatic hydrocarbons detected in 8 samples of raw material (swine rectum) and samples of smoked gentile were: benzo[a]anthracene, chrisene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a] pyrene, benzo[a,h]anthracene. Their residues were detected in all samples of finished product. European Regulation 835/2011 established two levels of PAHs content in meat products. According to first levels, in force until September 2014, only 2 out of 8 samples exceeded legal limit. According to the subsequent, more restrictive, limits all samples would be non-compliant. An improvement and a standardisation of traditional smoking procedures are recommended.

Education is observed in terms of institutional and systemic approaches, and the post-reform stage of its development is analyzed in the context of the modernization theory. Historical-dynamic analysis and comparative-historical method are mostly used when systemizing factual data.Results. The article reveals basic stages and characteristics of elementary public schools in the Perm province countryside during pre-vseobuch (compulsory education period. The dynamics of the educational process in reference to the number of schools and enrollments is shown; the scale of the process and the participation of the «zemstvo system» (i.e. district council and the Orthodox Church in it are estimated. The clergy’s view on parochial schools as a special type of educational institutions is also described. Difficulties faced by public school policy during the implementation of rural compulsory education in the province are marked. It is shown that to achieve total literacy in the rural areas in the pre-revolutionary period was impossible in spite of the accelerated speed of the school education and substantial progress in the organization of the compulsory primary education.Scientific novelty. Turning to the history of compulsory elementary schools in terms of the «compulsory education paradigm» offers the possibility to set clear criteria for assessing the level of development of the education system and show how the compulsory education environment was formed.Practical significance.

    Strong research evidence has shown that medical male circumcision significantly reduces heterosexual HIV acquisition among men. However, its effectiveness is enhanced by behavioural factors such as condom use. Currently, little is known of unprotected sex associated with male circumcision (MC) among alcohol-drinking tavern-going men, or whether engagement in unprotected sex may differ between men who have been traditionally circumcised and those who have been medically circumcised. The study sought to determine the relative importance of alcohol consumption and MC as correlates of unprotected sex and to compare the risk of engaging in unprotected sex between traditionally circumcised and medically circumcised tavern-going men from two rural villages in North-West province, South Africa. Data from 314 adult men (≥18 years) were analysed. The men were recruited from four bars/taverns using systematic sampling. They responded to questions regarding their demographic characteristics, alcohol consumption, circumcision status and method (where applicable), and engagement in unprotected sex. Descriptive analyses and bivariate and multivariate logistic regression analyses were conducted. Age, education, relationship status, alcohol consumption and traditional male circumcision (TMC) were independently and significantly associated with unprotected sex. Specifically, probable alcohol dependence and traditional circumcision were independent risk factors for engaging in unprotected sex among tavern-going men. Traditionally circumcised men had a higher risk of engaging in unprotected sex than medically circumcised men. Interventions aimed at reducing alcohol consumption, encouraging protective behaviour among men who have undergone TMC, and increasing condom use are needed in bar/tavern settings. HIV prevention education must be urgently incorporated into TMC programmes.

    Multiple sulfur isotope ratios (34S/33S/32S) of Archean bedded sulfides deposits were measured in the Yanlingguan Formation of the Taishan Group in Xintai, Shandong Province, East of China; δ33S =-0.7‰ to 3.8‰,δ34S = 0.1‰-8.8‰, △33S = -2.3‰ to -0.7‰ The sulfur isotope compositions show obvious mass-independent fractionation (MIF) signatures. The presence of MIF of sulfur isotope in Archean sulfides indicates that the sulfur was from products of photochemical reactions of volcanic SO2 induced by solar UV radiation, implying that the ozone shield was not formed in atmosphere at that time, and the oxygen level was less than 10-5PAL (the present atmosphere level). The sulfate produced by photolysis of SO2 with negative △33S precipitated near the volcanic activity center; and the product of element S with positive △33S precipitated far away from the volcanic activity center. The lower △33S values of sulfide (-2.30‰ to-0.25‰) show that Shihezhuang was near the volcanic center,and sulfur was mostly from sulfate produced by photolysis. The higher △33S values (-0.5‰ to-2‰)indicate that Yanlingguan was far away from the volcanic center and that some of sulfur were from sulfate, another from element S produced by photolysis. The data points of sulfur isotope from Yanlingguan are in a line parallel to MFL (mass dependent fractionation line) on the plot of δ34S-δ33S,showing that the volcanic sulfur species went through the atmospheric cycle into the ocean, and then mass dependent fractionation occurred during deposition of sulfide. The data points of sulfur isotope from Shihezhuang represent a mix of different sulfur source.

    为了揭示广东省稻飞虱迁入路径和虫源地分布,为其精细化预测预报及源头治理提供科学依据,根据广东省清新县、广州番禺区2010、2011年稻飞虱虫情资料,利用HYSPLIT-4轨迹分析平台和图形处理软件GrADS进行稻飞虱迁入轨迹及虫源地分析。结果表明:稻飞虱发生初见日(迁入)及各高峰日当天、前1天、前2天观测到有降水,下沉气流和降水是迫使稻飞虱集中降落的主要原因;广东省早稻期间稻飞虱主要发生在5月上旬至7月上旬,低空急流、西南气流及偏南气流为稻飞虱迁入广东提供了运载气流,其稻飞虱迁入的虫源地主要分布在越南、老挝南部、海南省及两广南部;广东省晚稻期间稻飞虱主要发生在9月上旬至10月上旬,稻飞虱随偏北气流开始由北往南回迁,稻飞虱迁入的虫源地主要分布在湖南及江西等稻区。%In order to determine the immigration trajectory and source areas of rice planthopper in Guangdong Province, and to establish a basis for refined forecasting and source suppression, the geographic distribution of the source area of early immigrant rice planthopper was analyzed by GrADS (Graphics Processing Software), HYSPLIT-4, a trajectory analysis software for the simulation of migration pathways, and light trap catch data from 2 plant protection stations (including Qingxin, Panyu). The results indicated that precipitation was observed the immigrant and peaks days, as well as one day and two days ago. Downward airflow and precipitation were main two reasons of forcing rice planthopper to land focusly. The peaks of early immigrants of rice planthopper were from early May to early July for early-rice growth reason. Lower jet, southwest and south flows provided carrying force for immigrant rice planthopper, and most of the early immigrants came from Vietnam, southern Laos, Hainan Province, southern Guangdong Province and Guangxi Province

  13. Nitrate and nitrite contamination of sub-surface water in some areas of North West Frontier Province (N.W.F.P.) Pakistan

    International Nuclear Information System (INIS)

    Over the past few years, nitrate and nitrite contamination of sub-surface water samples from Peshawar, Charsada, Mardan and Nowshera districts of NWFP has been studied. In all the areas under study, nitrate concentration of sub-surface water was found to be below WHO approved limit of 45 mg/l. Whereas city area after 1987 showed a decreasing level of nitrate contamination of sub-surface water, it appeared to be on the increase in water samples from the outskirts of Peshawar-Charsada road. No uniform increasing or decreasing patterns of nitrate contamination were observed for water samples from cantonment, University and Hayatabad, areas of Mardan, Charsada and Nowshera under study. The nitrate contamination of sub-surface water appeared to be due to both the agricultural activities as well as human and animal wastes. A few sub-surface water samples from Peshawar city, Mardan and Nowshera areas indicated high concentration of nitrite, which is alarming in view of the earlier reports showing absence of nitrite in water samples from these areas. However, since 1993, nitrite presence has not been detected in sub-surface water samples from all the areas under present investigation. (author)

    Source spectra, corner frequency and zero frequency amplitudes in near-source conditions were measured using waveform data from 989 earthquakes with magnitudes larger than ML2. 0 observed by the Beijing Digital Telemetry Seismic Network in the Capital Circle Region of China and its surrounding areas from January 2002 to June 2006 by the Brune model. Relevant formulas that were used for the calculation of dynamic source parameters include rupture radius, seismic moment, seismic energy, stress drop, and apparent stress. Scaling relations and characteristics of temporal-spatial variations of these dynamic parameters before the Ms5.1 Wen'an earthquake in Hebei Province that occurred on July 20, 2006 were analyzed. Results show that apparent stress, stress drop, and the ratio of seismic energy to the rupture radius had relatively high values in some areas before the Wen'an earthquake. These high-value concentration areas were mainly distributed in the North China Plain seismic zone. As is seen from the time curves, parameters, such as apparent stress, stress drop, and ratio of seismic energy to rupture radius underwent significant ascending processes before the Wen'an earthquake, but the variation in the corner frequency showed a descending trend. This result might be related to the enhancement of stress in the North China Plain seismic zone before the earthquake.

    Full Text Available Introduction & Objective: Cutaneous Leishmaniasis is caused by obligatory intracellular parasite of genus Lieshmania. The disease is reported from more than half of Iran's provinces. Various species of sand flies are vector of the disease. Determination of vectors and gaining knowledge about them are important for devising of control program. Materials & Methods: This survey was performed as a cross-sectional study in order to determine the vector(s of cutaneous leishmaniasis in Damghan district during 2008-2009. Sand flies were collected from indoors and outdoors by sticky traps twice in month from April to November. Head and last abdominal segments of the samples were removed and mounted in a drop of Puri’s medium and identified. The rest of the sand flies' bodies was subjected to DNA extraction for molecular detection of Leishmania parasite by Nested PCR using specific primers of minicircle kinetoplast DNAResults: Totally, 6110 sand flies in 8 species were collected. P. papatasi had high density (46.7%. Examination of 280 female sand flies by Nested PCR showed that 28 sand flies (10%include 24 specimens P.papatasi (85.7% and 4 specimens P.caucasicus(14.3%were found naturally infected with L.major. The highest rate of infected sandflies were observed in rodents burrow (42.9%. Maximum rate of sand fly infection was in September (89.3%. Conclusion: With respect to high density of P.papatasi and isolation of L.major from it, this species was the main vector of the disease. Detection of L.major from P.caucasicus shows that this species was the secondary vector in rodent burrow. The highest rate of sand leis infected was in September, so personal protection in this month is very important and necessary. Regarding to the high density of vectors and high infection rate of them taking actions to decrease the sand fly abundance and prevention of human biting are suggested.(Sci J Hamadan Univ Med Sci 2012;18(4:47-52

  17. A geological and hydrogeochemical investigation of the uranium potential of an area between the Orange and Kuruman Rivers, northwestern Cape Province. V.1

    International Nuclear Information System (INIS)

    An extensive geological, hydrological and hydrochemical study was conducted to determine the uranium potential of an area which includes the greater part of the Gordonia District and part of the bordering Kuruman District. The area is situated between 21 and 22 degrees east, the Kuruman River in the north and the Orange River in the south. All berohole information germane to the area, such as Government and private drill records have been studied. As a result of this study maps of the area have been compiled, showing surface and pre-Karoo geology, the pre-Karoo and pre-Kalahari topography and the thickness of the Karoo and post-Karoo cover. Contour maps of water levels were compiled from which a regional east-west flow pattern was deduced, indicating a large groundwater basin which could be divided into four smaller basins. Hydrochemical studies substantiate the inferred flow pattern of the groundwater. Of prime importance in this investigation was the study of the distribution of uranium in the groundwater of the area and its association with the various lithologies encountered. Radiometric borehole logging of all accessible boreholes in the most promising areas delineated by this study confirmed the presence of uranium mineralisation in the depositional basins (in particular the Dwyka Tillite Formation) west of the granite-gneiss ridge. Uranium mineralisation in surficial deposits was also discovered as a result of the reassessment of radiometric airborne data obtained previously. It is concluded that potential economic uranium deposits may exist in the Dwyka Tillite Formation northwest of Upington and in the surficial diatomaceous earth deposits on the farm Rus-en-Vrede

    Full Text Available The objective of the proposed Highveld National Park (HNP is to conserve a considerable area of the poorly conserved Rocky Highveld Grassland and Dry Sandy Highveld Grassveld of the western Grassland Biome in South Africa. The park has not yet been proclaimed, but is currently under the management of the North West Parks and Tourism Board. The main aim of this study was to classify and describe the vegetation in the Spitskop area in the HNP. The areas affected by soil degradation were on the midslopes, footslopes, valley bottomland and the floodplains around the Spitskop hill. The concentrated grazing around the Spitskop area was also influenced by the existing dam in the floodplains. Floristic and soil degradation data were collected and used to classify and describe the plant communities of the Spitskop area. Vegetation sampling was performed by means of the Braun-Blanquet method and a total of twenty plots were sampled. A numerical classification technique (TWINSPAN was applied to the floristic data to derive a first approximation of the main plant communities. Further refinement was achieved by Braun-Blanquet procedures. The final results of the classification procedure were presented in the form of a phytosociological table, with three major communities and three subcommunities being described. Canonical correspondence analysis was used to determine the direct correlation between plant communities and soil degradation types. Soil compaction and sheet erosion were found to be the most significant variables determining plant community composition. Rill and gully erosion were shown to be of lesser significance in explaining the variation in plant communities. Conservation implications: Grasslands are amongst the most threatened biomes in South Africa, yet less than 1.3% are currently being conserved. The HNP has significant value for biodiversity conservation and the protection of this area will contribute to the preservation of the highly

    The Zhangwu-Heishan area is located to the east of the Fuxin-Yixian Basin and is mostly covered with volcanic rock.At various periods,different geologists had varying opinions about their age and periods of volcanic eruptions,especially on sequences between volcanic rock and main coal-beating strata,which affect the direction of searching for coal,as well as prospecting the entire research area.During our study,we carried out detailed field investigations in this research area; observed and recorded the main representative outcrops of volcanic rock.We collected over 20 volcanic rock samples and tested the Sensitive High Resolution Ion Microprobe Ⅱ (SHRIMP Ⅱ) U-Pb isotope age of 11 samples.The age of our volcanic rock samples ranged between 56.0 ± 2.9 and 132.3 ± 2.3 Ma.After taking earlier investigations into consideration,we concluded that,except for a suite of paleogene olivine basalt,the volcanic rock in the Zhangwu-Heishan area is younger than the coal-beating Shahai Formation.It is therefore most unlikely to find coal seams equivalent to those of the early Cretaceous Shahai Formation in Fuxin Basin below volcanic rock.

Usually there were more than 1 hydrogeological units in a mining area,which was very different to those in north China. In view of the uniqueness of Guizhou Province mining are-as,this thesis reviewed the mining area planning and analyzed characteristics of groundwater environ-ment in Zhijin Mining Area ,and then put forward comments for groundwater environmental impact assessment and predicting methods for Guizhou Province mining areas. For example,when we calcu-lated the height of water flowing fractured zone,influenced radius of groundwater and influenced wa-ter volume,plenty of typical mines should be included. When drinking water source was involved, each drinking spring should be analyzed.

  6. Neotectonics in the maritime provinces

    International Nuclear Information System (INIS)

    Seismic risk assessment in the Maritime Provinces requires input from not just historical, but also geological sources. A detailed search through published and unpublished geological literature reveals many examples - some probable, some possible -of neotectonic movement in the area. Examples range in tectonic significance from those that reflect exaggerated local imbalance to those that signify deep-seated stress. Evidence for neotectonism in the Maritimes is multidisciplined. It includes deformation in bedrock and quaternary deposits, and regional warping. Recent movement also is indicated by changes in relative sea level, in situ stress fields and geodetic fluctuations. Finally, and most unequivocally, neotectonism in the Maritime Provinces is manifested as the seismic events that have sporadically affected the area throughout its recent geological history, and continue up to the present day. 288 refs

    The Alkaline porphyries in the Beiya area are located east of the Jinshajiang suture, as part of a Cenozoic alkali-rich porphyry belt in western Yunnan. The main rock types include quartz-albite porphyry, quartz-K-feldspar porphyry and biotite-K-feldspar porphyry. These porphyries are characterised by high alkalinity [(K2O + Na2O)% > 10%], high silica (SiO2% > 65%), high Sr (> 400??ppm) and 87Sr/86Sr (> 0.706)] ratio and were intruded at 65.5??Ma, between 25.5 to 32.5??Ma, and about 3.8??Ma, respectively. There are five main types of mineral deposits in the Beiya area: (1) porphyry Cu-Au deposits, (2) magmatic Fe-Au deposits, (3) sedimentary polymetallic deposits, (4) polymetallic skarn deposits, and (5) palaeoplacers associated with karsts. The porphyry Cu-Au and polymetallic skarn deposits are associated with quartz-albite porphyry bodies. The Fe-Au and polymetallic sedimentary deposits are part of an ore-forming system that produced considerable Au in the Beiya area, and are characterised by low concentrations of La, Ti, and Co, and high concentrations of Y, Yb, and Sc. The Cenozoic porphyries in western Yunnan display increased alkalinity away from the Triassic Jinshajiang suture. Distribution of both the porphyries and sedimentary deposits in the Beiya area are interpreted to be related to partial melting in a disjointed region between upper mantle lithosphere of the Yangtze Plate and Gondwana continent, and lie within a shear zone between buried Palaeo-Tethyan oceanic lithosphere and upper mantle lithosphere, caused by the subduction and collision of India and Asia. ?? 2006 Elsevier B.V.

    Full Text Available This contribution introduces a fractal filtering technique newly developed on the basis of a spectral energy density vs. area power-law model in the context of multifractal theory. It can be used to map anisotropic singularities of geochemical landscapes created from geochemical concentration values in various surface media such as soils, stream sediments, tills and water. A geochemical landscape can be converted into a Fourier domain in which the spectral energy density is plotted against the area (in wave number units, and the relationship between the spectrum energy density (S and the area (A enclosed by the above-threshold spectrum energy density can be fitted by power-law models. Mixed geochemical landscape patterns can be fitted with different S-A power-law models in the frequency domain. Fractal filters can be defined according to these different S-A models and used to decompose the geochemical patterns into components with different self-similarities. The fractal filtering method was applied to a geochemical dataset from 7349 stream sediment samples collected from Gejiu mineral district, which is famous for its word-class tin and copper production. Anomalies in three different scales were decomposed from total values of the trace elements As, Sn, Cu, Zn, Pb, and Cd. These anomalies generally correspond to various geological features and geological processes such as sedimentary rocks, intrusions, fault intersections and mineralization.

    2006-01-01

    Previous studies on erosional relations between inter-gullied and gullied lands have mainly concentrated on exploration of water and sediment relations, with few quantitative studies of evolution relations between inter-gullied land and gullied landform erosion in small catchments. This paper, using information from a 1:5000 digital orthophotomap (DOM), digital elevation model(DEM), and topographic map of the same period and of the same scale, quantitatively analyzes the impact and interactions of inter-gullied and gullied land geomorphologic characteristics on the dissected extent of a catchment using orthogonal polynomial regression analysis. Results indicate that gullies play a leading role in the catchment morphologic evolution and extent of cracked ground surface. When inter-gullied land areas are the same, a 0. 1 km2 gullied land area has the maximum effect on the erosive evolution intensity of the catchment cracked degree. The smaller the catchment area is, the greater the extent of cracked ground surface and gully intensity would be. The geomorphologic evolution mechanism of gullied catchments can be explained as a function of geomorphologic indicators of inter-gullied and gullied land characteristics.

  12. Past and future fracturing in AECL Research areas in the superior province of the Canadian Precambrian Shield, with emphasis on the Lac du Bonnet Batholith

    International Nuclear Information System (INIS)

    The likelihood that future fracturing, arising from geologic causes, could occur in the vicinity of a nuclear fuel waste repository in plutonic rock of the Canadian Precambrian Shield, is examined. The report discusses the possible causes of fracturing (both past and future) in Shield rocks. The report then examines case histories of fracture formation in Precambrian plutonic rocks in AECL's Research Areas, especially the history of the Lac du Bonnet Batholith, in the Whiteshell Area, Manitoba. Initially, fractures can be introduced into intrusive plutonic rocks during crystallization and cooling of an intrusive magma. These fractures are found at all size scales; as late residual magma dyking, hydraulic fracturing by retrograde boiling off of hydrothermal fluids, and, in some cases, through local differential cooling. Subsequent fracturing is largely caused by changes in environmental temperature and stress field, rather than by alteration of the material behaviour of the rock. Pluton emplacement during orogeny is commonly accompanied by uplift and erosional exhumation, altering both the tectonic and the lithostatic stresses, the rock temperature gradient and the pore fluid characteristics

    Background: Imported malaria is a major threat to neighboring malaria-eliminating countries such as P.R. China and is difficult to monitor. A molecular survey of febrile patients with a history of traveling abroad along the Myanmar-China endemic border areas from January 2008 to August 2012 was carried out. The rates of infection with species of Plasmodium and compliance of microscopy diagnosis with nested PCR (Polymerase Chain Reaction) results were calculated. Results: Plasmodium genus-specific nested PCR confirmed that 384 cases were positive. Further species-specific nested PCR showed that the rate of Plasmodium vivax infection was 55% (213/384); that of Plasmodium falciparum was 21% (81/384) and 17% (67/384) of cases were co-infection cases of P. vivax and P. falciparum; the remaining 6% (23/384) of cases were caused by other species, such as Plasmodium ovale, P. malaria, P. knowlesi or mixed infections of Plasmodium. In total there was 13% (50/384) false microscopy diagnosis including 6% (22/384) error in species diagnosis and 7% (28/384) undiagnosed cases in co-infection or low parasitemia malaria cases. Conclusions: This study indicates that there are considerable numbers of malaria cases in the China-Myanmar endemic border areas that remain undiagnosed or misdiagnosed by microscopy, especially in low-level and/or complex co-infection cases. It is urgent to develop accurate rapid diagnostic tests and apply PCR confirmation for efficient surveillance. PMID:24954235

    Full Text Available Introduction: Over the last decade, the role of clinical librarians in assisting general practitioners to provide better health care has been proved. Rapid progress in telecommunication technology has emerged this question. Could clinical librarians be able to assist general practitioners working in rural and remote areas through Information and communication technologies? This project sought to evaluate whether clinical librarians are able to provide accurate and updated information to physicians. Method: Twenty general practitioners working in non rural working in remote areas of Kerman were requested to ask clinical librarians 5 questions through a phone line each over the period of two months whenever they felt they need to have more information on a matter related to their practice. Then all questions and answers were evaluated by expert medical specialists and pharmacists who were academic staff of Kerman University of Medical Sciences . Clinical librarians’ role was also evaluated by an electronic questionnaire sent to general practitioners. Results: Over 80 percents of the answers were evaluated as perfect and 10 percent as good. Only 10 percent of the answers were scored as wrong. Conclusion: Clinical librarians are able to provide reliable information to remote and rural physicians, The fact which has been also verified by the specialists. However, clinical librarians need to improve their English language and their knowledge about online search strategies and basic medication. Telecommunication infrastructure and suitable internet speed for online search by librarians are very important.

    Objective To look into the current distribution of iodine deficiency area in Shandong province and to guide the re-defined iodine deficiency area and to supplement iodine scientifically. Methods In 2008, 100 iodine deficiency counties(cities, districts), designated in Shandong province's "to supplement iodized salt to eliminate the hazard of iodine deficiency management regulations", were selected in the study. One to three samples were collected from water source which was used by the majority of local residents in the 100 iodine deficiency places and iodine concentration was tested by As3+-Ce4+ catalyzing spectrophotometry. Results A total of 65 716 water samples were collected. Sample recovery efficiency reached 99.8%(65 572/65 716). The median water iodine was 5.57 μg/L, with 82.05%( 1097/1337 ) of the township(town) met criteria for the classification of iodine deficiency areas(water iodine < 10 μg/L), 17.43%(233/1337) of the township (town) water iodine moderate(water iodine 10 - 150 μg/L), and 0.52%(7/1337)of the township(town) should be defined high iodine areas(water iodine > 150 - 300 μg/L). Conclusions The iodine deficiency areas should be redefined because water iodine concentrations of iodine deficiency areas have changed. We suggest that the smallest place to supply salt with different range of iodine content is set to the township(town).%目的 了解山东省碘缺乏地区居民饮水含碘量分布现况,指导碘缺乏地区的重新划定及科学补碘措施的实施.方法 2008年以划定的100个碘缺乏县(市、区)作为调查范围,以自然村为调查单位,采集1~3份饮用人数最多的水源样品,用砷铈催化分光光度法检测水碘.结果共收集水样65 716份,回收样品有效率达到99.8%(65 572/65 716),水碘中位数为5.57μg/L.有82.05%(1097/1337)的乡(镇)符合碘缺乏地区划分标准(水碘<10 μg/L),17.43%(233/1337)的乡(镇)水碘适中(水碘10~150μg/L),0.52%(7/1337)的乡(

  6. Association of PCB, PBDE and PCDD/F body burdens with hormone levels for children in an e-waste dismantling area of Zhejiang Province, China

    International Nuclear Information System (INIS)

    Increased electronic waste (e-waste) has raised public concerns regarding exposure to numerous toxic contaminants, particularly polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs). In China, the body burdens of PCBs, PBDEs and PCDD/Fs are associated with thyroid hormones in populations from e-waste dismantling sites; however, it is unclear whether this association occurs in children. In this study, we determined the serum levels of PCBs, PBDEs and PCDD/Fs and the endocrine hormones including free triiodothyronine (FT3), total triiodothyronine (TT3), free thyroxine (FT4), total thyroxine (TT4), thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), cortisol and growth hormone (GH) in 21 children from an e-waste dismantling area and 24 children from a control area. The results showed that the mean levels of ∑ PCBs and ∑ PBDEs in the exposure group were significantly higher than in the control group (40.56 and 32.09 ng g−1 lipid vs. 20.69 and 8.43 ng g−1 lipid, respectively, p < 0.01 for each), and the mean level of ∑ PCDD/Fs in the exposure group was higher than in the control group, but the difference was not significant (206.17 vs. 160.27 pg g−1 lipid, p > 0.05). For the endocrine hormones, we did not find significant differences between the exposed and control groups, although the mean levels of FT3, TT3, TT4, ACTH, cortisol and GH were higher, whereas the mean levels of FT4 and TSH were lower in the exposed group. The mean level of ∑ PBDEs was positively correlated with the mean levels of ∑ PCBs (r = 0.60, p < 0.05) and ∑ PCDD/Fs (r = 0.61, p < 0.05). Furthermore, the mean level of ∑ PBDEs was positively correlated with ACTH (r = 0.61, p < 0.05). In conclusion, our data suggested that exposure to e-waste dismantling environment increased the body burdens of PCBs and PBDEs in local children and that these contaminants released from the e

    We revisit the environmental Kuznets curve (EKC) hypothesis using 1987-1995 data for Chinese provinces. A comparison of off-sample (1996-2004) predictions to actual emissions indicates that more stringent rules are still needed to fight industrial (waste water and dust) pollution. Auxiliary regressions show that conditional on income, northern provinces have lower industrial waste water pollution; non-coastal and provinces with smaller secondary industry shares have lower industrial (waste wa...

    Full Text Available Hand, foot and mouth disease (HFMD has been a substantial burden throughout the Asia-Pacific countries over the past decades. For the purposes of disease prevention and climate change health impact assessment, it is important to understand the temperature–disease association for HFMD in different geographical locations. This study aims to assess the impact of temperature on HFMD incidence in an inland city and a coastal city and investigate the heterogeneity of temperature–disease associations. Daily morbidity data and meteorological variables of the study areas were collected for the period from 2007 to 2012. A total of 108,377 HFMD cases were included in this study. A distributed lag non-linear model (DLNM with Poisson distribution was used to examine the nonlinear lagged effects of daily mean temperature on HFMD incidence. After controlling potential confounders, temperature showed significant association with HFMD incidence and the two cities demonstrated different impact modes ( I2= 96.1%; p < 0.01. The results highlight the effect of temperature on HFMD incidence and the impact pattern may be modified by geographical localities. Our findings can be a practical reference for the early warning and intervention strategies of HFMD.

    Full Text Available During this study selected direct and indirect educational methods were evaluated as a means of decreasing the prevalence of schist some infections in school children living in a schistosomeendemic area. Two direct (puppet show and flip chart and three indirect (notice board, poster and education via parents or guardians educational methods were evaluated. Schist some infected learners were identified by means of parasitological methods, their knowledge concerningschistosomiasis was tested in a questionnaire and information regarding water and sanitation facilities at their disposal was collected. Local health authorities facilitated treatment for this disease, while local teachers were involved in conveying the various educational programmes. Anoticeable increase in the learner’s knowledge regarding schistosomiasis was evident after only two educational opportunities, while a significant decrease in the cumulative prevalence of infection was recorded during the investigation among all the groups receiving education. Statistical analyses revealed that the puppet show, flipchart and poster were the most effective methods used to lower the prevalence of infection, while involving parents or guardians in the process proved to be the least effective method employed during the study.

    Microbially induced sedimentary structures (MISSs) are commonly present in siliciclastic shallow marine settings following the end-Permian mass extinction, but have been rarely reported in the post-extinction terrestrial ecosystems. Here, we present six types of well-preserved MISSs from the upper Sunjiagou Formation and lower Liujiagou Formation of Induan (Early Triassic) age in the Yiyang area, Henan Province, North China. These MISSs include: polygonal sand cracks, worm-like structures, wrinkle structures, sponge pore fabrics, gas domes, and leveled ripple marks. Microanalysis shows that these MISSs are characterized by thin clayey laminae and filamentous mica grains arranged parallel to bedding plane as well as oriented matrix supported quartz grains, which are indicative of biogenic origin. Facies analysis suggests that the MISS-hosting sediments were deposited in a fluvial sedimentary system during the Early Triassic, including lake delta, riverbeds/point bars, and flood plain paleoenvironments. Abundant MISSs from Yiyang indicate that microbes also proliferated in terrestrial ecosystems in the aftermath of the Permian-Triassic (P-Tr) biocrisis, like they behaved in marine ecosystems. Microbial blooms, together with dramatic loss of metazoans, may reflect environmental stress and degradation of terrestrial ecosystems or arid climate immediately after the severe Permian-Triassic ecologic crisis.

    The old reservoir areas built in 1950s-1970s left behind many socio-economic problems, because of the administrative backward migration and little migration fund, and all these problems would be tied to land. Based on interviewing with peasant households, combining land use survey and socio-economic statistical index, this paper analyzed land use change and its corresponding driving forces in Linshui reservoir area of Dahonghe Reservoir. Results showed that land use change in the reservoir area was mainly embodied on low-lying land submergence and migration requisition land. The former changed the land use patterns, and the latter mainly reconstructed original land property and made land over-fragmented. Cultivated land per capita was 0.041ha in this area, below the cordon of cultivated land per capita enacted by FAO. Currently, there were still 30.25% of peasant households being short of grain in trimester of one year, and there were 35.27% of people living under the poverty line. The conditions of eco-environment in Linshui Reservoir Area were worse, and healthy and sub-healthy eco-environment accounted for less proportion, composed of green belt around the reservoir area and paddy field ecosystem, and economic forest and orchard ecosystem, respectively. The stress of the reservoir project was macroscopic background to analyze the driving factors of land use change, and real underlying diving factor of the land use change in the area was the change of cultural landscape under the stress of reservoir project. The rapid increase of population was the key factor to induce the change of man-land relationship in the reservoir area, the low level of rural economy was the crucial factor to decide how migrants input for production, and the belief of migrants, influencing the land use patterns in a certain extent, was the inducing factor to keep land use stable. The low-lying submergence and infrastructure construction accompanied the reservoir project were leading

    Full Text Available Blowfly strike and the methods used to combat blowfly strike were recorded on 33 properties in the Rûens area of South Africa during 2003/2004. Data were recorded on Merino and Dohne Merino hoggets (n = 4951 with at least 3 months’ wool growth. The following data were captured: presence or absence of strike, site of the strike (body or breech, presence or absence of dermatophilosis as well as subjective scores for wool quality and wool colour. Control measures recorded include: chemical treatment (preventative and spot treatment, crutching, mulesing and the use of the Lucitrap® system. Blowfly strike was not significantly influenced by gender or breed. Hoggets suffering from dermatophilosis were more likely to be struck, compared with contemporaries not suffering from the skin disorder (0.057 vs 0.027; P < 0.05. Merino hoggets generally had higher scores than their Dohne Merino contemporaries for wool quality (32.6 vs 27.4; P<0.05 and wool colour (29.0 vs 27.2; P<0.05. There was an indication that the Lucitrap® system may have reduced flystrike, but the effect was not statistically significant (P = 0.19 for overall strikes and P = 0.12 for body strike. The Mules operation benefited overall flystrike (0.013 vs 0.110; P < 0.05; mainly through an effect on breech strike (0.010 vs 0.109; P < 0.05. The proportion of fly strikes increased with wool length, and declined with an increase in farm size in wool colour score. None of the ethically acceptable control measures assessed could substantially reduce blowfly strike on their own, and an integrated pest management programme was proposed.

    目的 了解江苏省部分地区德国小蠊对溴氰菊酯、高效氯氰菊酯、敌敌畏、残杀威、乙酰甲胺磷5种常用杀虫剂的抗药性程度,以便通过抗性程度来指导科学、合理的用药.方法 药膜接触法.结果 江苏省4个地市的德国小蠊野外品系对上述5种杀虫剂的平均抗性系数分别为17.0、8.4、3.2、1.6和4.4.南京、南通、淮安品系对溴氰菊酯的抗性倍数最高,分别为22.9、20.6、16.1;丹阳品系对高效氯氰菊酯的抗性程度最高(R=10.9).各品系德国小蠊对残杀威的抗性程度较低(R=1.6).结论 江苏地区4个野外品系德国小蠊对溴氰菊酯、高效氯氰菊酯、敌敌畏和乙酰甲胺磷均产生不同程度的抗性.%Objective To estimate the susceptibility or resistance of Blattella germanica, including normal strain and four field-collected strain to deltamethrin, beta-cypermethrin, dichlorvos, propoxur and acephate in some areas in Jiangsu Province. Methods Contacting with chemical cover. Results The average resistance ratios of field-collected strains to deltamethrin, beta-cypermethrin, dichlorvos, propoxur and acephate were 17.0, 8.4, 3.2, 1.6 and 4.4 respectively. The resistance ratios of deltamethrin were high in Nanjing, Nantong and Huaian four tield - collected strain( R = 22. 9 , 20. 6 , 16.1). The resistance also reached the high level to beta - cypermethrin in Danyang strain ( R = 10. 9) . The average resistance ratios of field - collected strains to propoxur was low ( R = 1. 6). Conclusion Field collected strains of Blattella germanica in Jiangsu Province have already developed different resistance to four kinds of insecticides.
